Section 1 – Grain Bin Specifications









Section 2 – Bin Erection

Chief Industries, Inc. will not assume any responsibility for parts damaged due to faulty or

improper erection procedures.

Chief Industries, Inc. recommends that Bin Jacks be used for all bins taller than 8 rings

and all bins larger than 30’ in diameter.

WARNING:

The allowable lifting capacity of the BIN JACKS must never be exceeded. Always check Bin

weight to insure a safe and trouble free erection.

Grain Bin Color Codes

Chief Grain Bins are color coded based on bin diameter. Components such as Roof Rafters,

Wind Rings, and Base Angle will be marked with the following Color Codes to help identify

them.

Bin Size Color Code Bin Size Color Code

B. Checking Shipment

Check your shipment at the time of pickup and delivery against the packing list furnished

with the shipment. If a shortage exists or if any damaged material is evident, note such

shortage or damage on the freight bill before you sign for the shipment.

Claims of shortages will not be honored after thirty days from receipt of shipment.

Parts that are short or damaged are the responsibility of the delivering carrier, not the

manufacturer or dealer.

It is advisable to reorder damaged or missing parts immediately so that there will be no

delay in erecting the bin. After receiving the invoice for the reordered material, file a

claim with the delivering carrier at once.

The galvanized panels leave our plant in prime condition; store off the floor in a heated

room if possible. If stored outside, place panels down, off the ground. Upon arrival of

shipment if you are not certain whether or not moisture is present, store panels on edge or

on end allowing 1/4“ air space between panels until dry. Exposure to trapped moisture

can cause white rust, which will void the warranty.

C. Stop and Study

Before beginning erection of the bin, take the time to thoroughly study the construction

methods in this manual. It will save you both time and money.

Important: The peak load capacities listed under Auxiliary Roof Loads must not be exceeded. If your

application will exceed the listed values, contact Chief Industries for recommendations.

Chief Industries makes no warranty concerning parts, accessories or equipment not

manufactured by Chief Industries.

D. Site Selection

Choose a site that has good drainage away from the bin so that water will not stand around

the bin. The soil should be firm and preferably without fill. If fill is required, water and

compact the fill material to avoid uneven settlement. A field investigation of the soil

bearing conditions is recommended especially for larger grain bins where the foundation

loads and floor pressure become large. A licensed engineering firm should be employed to

take soil borings, determine the maximum allowable soil pressure and design the bin

foundations and floor slab accordingly.


E. Bin Jack Erection

Position the structure you provided to hold the Inner Ring at its approximate height,

centering the Inner Ring on the center of the Bin.

Use at least one Bin Jack per Sidewall Sheet. (For example, on the #18 Bin, use 18 Bin

Jacks, etc.)

The application of one bin jack per sidewall sheet will minimize sidewall distortion during

erection. Failure to use the proper quantity of jacks may result in inward-outward lay of the bin

sidewall or even permanent distortion of the bin sidewall sheets.

The recommendation of at least one Bin Jack per sidewall sheet is based on keeping the bin

round, refer to the warning below, and make sure the lifting capacity of the jack is

sufficient for the weight of the bin. Note that all jacks may not shift equally, Therefore

make sure the lifting capacity rating by the jack manufacturing is met.

WARNING:

If it is necessary to leave the construction site for any length of time before the Bin is

completed and anchored to the concrete, the Bin must be securely tied down.


F. Assembling Sidewall Sheets

All bolts are washer head bolts with sealing washers S.A.E. Grade 8, with whiz flange

nuts. Grade 8 bolts are marked with six radial lines on the bolt head as shown. If these

descriptions do not correspond with the bolts shipped with the bin, please contact the

customer service department immediately. Do not substitute any other Bolts.

Bin bolts must be TIGHT. The following table contains recommended minimum and

maximum torque values.

BOLT DIA. TORQUE FT. LBS

(INCHES) MINIMUM MAXIMUM

5/16" 22 28

7/16" 60 75

Tighten the bin bolts from the inside of the bin (nut end of the bolt) to eliminate “spin

off” of the sealing washer.

USE ONLY THOSE BOLTS SUPPLIED BY CHIEF INDUSTRIES.

THE SUBSTITUTION OF BOLTS FROM OTHER SOURCES IS NOT PERMITTED.

The top 2 rings of the bin and the roof should be assembled on the concrete bin floor.

Attach the lifting brackets to the bolts at the endlaps of the sidewall sheets. The lifting

brackets must be attached to the endlap by at least 8 standard bin bolts.

NOTE: Proper bolting sequence MUST be followed at all times.


The Sign Sheet must be installed in the second ring as shown in figures below.

(Shown installed on a 2 stiffened bin)

(Shown installed on a 3 stiffened bin)

Install the Sign Sheet by field drilling (6) six ½” holes in the Sign Sheet and stiffeners as shown

above. Bolt the Sign Sheet to the stiffeners with (6) six 7/16” bolts.


Assembling top ring

Locate the proper gauge of sidewall sheets needed for the top ring from the gauge chart. Lap and

caulk sheets as shown below. Locate top stiffeners and install on top ring.

Note: Top Sheets have special punching on the top of the sheet at the stiffener holes for the

rafter to attach to. Leave bolts out of top (4) stiffener holes until eave brackets are

attached.

Wipe off the outside ends of all the Sidewall Sheets to remove excess oil so that the Strip

Caulking will adhere to the metal. Place the Strip Caulking as near to the vertical inside edge of

sheet at every vertical seam.

On Bins 12 gauge or heavier a horizontal strip of caulking is needed on the inside at the center

bottom of the Sidewall sheet located on the hill near to the bottom holes. This strip of caulking

should fit where the endlap of the next ring Sidewall Sheets bolts up to this location.


G. Roof Panel Location

The rafters need to be bolted directly behind a top 2 ring stiffener, the roof panel rib will line up

directly above the rafter from the peak to the eave. (There is 1 Rafter and 4 roof panels per

sidewall sheet.)


H. Crane and Jack Capacities

Crane Capacity:

The total roof dead load for each of the respective bin roof sizes is shown in the table below.

This weight includes the roof panels and all structural members (roof beams, compression rings,

bolts, ect.)

When determining the crane capacity necessary to erect the roof structure, the booming distance

must be considered. If the cane sizes available will not lift the roof structure (using one crane),

two cranes may be used, utilizing a spreader bar. The spreader bar must be adequately designed

to carry the entire roof dead weight.

CB12 Total Roof Weight = 5,100 lbs.

Peak Heights

All peak heights listed below are to the bottom of the peak ring from the ground with (2) Titan

sidewall sheet rings installed. Deduct 42 1/2” from the peak heights when only one ring of

sidewall sheets are installed.

Ring Segments

After all rafters are installed, begin installing ring segments to the clips that are bolted to the

rafters as shown. Install ring segments with 1/2” x 1-1/2” bolts with washers against the ring

segments.


Roof Struts

Attach roof struts with 1/2” x 1-1/2” bolts between center set of holes in Rafter “A” and center of

ring segment as shown below. Struts are placed between every rafter.


Eave Brackets

Attach Left Hand and Right Hand Eave Brackets to the inside of the top sidewall sheet behind

the 2 ring top stiffener, with 7/16” x 1-1/2” bin bolts with bolt head inside the bin, as shown.

(Note: one L.H. and one R.H. Eave Bracket per sidewall sheet equally spaced around the bin)

When all ring segments and struts are installed tighten all bolts in structure.


D. Roof Panel Assembly

Attach flashing clips to peak ring with 7/16” x 1-1/4” bin bolts. Place plastic foam around peak

ring under flashing clips.


Roof Panel flashing extensions

The extensions come in 8 equal pieces install clockwise around the peak and attach with 7/16” x

1-1/4” bin bolts. (Note: Flashing Extensions must be started as shown to properly align roof

panels, Center first extension on hole that is aligned with rafter and flashing hole in peak ring.


Place Foam on edge of extension to seal between extensions.


Roof Panel Installation

1. Install strip caulking between top end of roof panels and roof panel flashing. Use 5/16” x 3/4”

bolts at top end of panel. Bolt roof panels to top angle with 5/16” x 3/4” bolts.

2. Proceed by installing additional roof panels in the following manner: Always working to the

right around the bin, place strip caulking on right rib of the previously installed roof panel (top

only). Placing roof panel in a vertical position, lock the left rib of the panel being installed over

the right rib of the previously installed panel. Tip the roof panel down. As each roof panel is set

into place, insert a lining punch through the hole in the rib at the bottom of each roof panel.

Temporarily clamp the two roof panels together with vise grips so that the punch can be removed

and a 5/16” x 3/4” bolt inserted and hand tightened. Continued installation of roof panels as

described in preceding steps.

3. All bins are equipped with one manhole and a roof ladder as standard. Extra manholes should

be spaced evenly around the bin.

4. When the last roof panel is placed, it will have to be interlocked by using a rubber mallet.

Starting at the top and working down, tap the vertical rib until it is sealed to the other panel.

Align roof panel holes and insert 5/16” x 3/4” bolts in the same manner as previously described.


5. Attach the roof panels to the roof joist using two #12 x 1” self-drilling screws per panel as

shown.


E. Cap Flashing

The cap flashing comes in 8 equal pieces; install the cap flashing to the peak ring with the 7/16”

x 1-1/4” bin bolts. After cap flashing pieces are attached to the peak ring drill screw cap flashing

together where it overlaps with #12 x 1-1/4” self-drilling screws.


Section 4 – Typical Roof Accessories

A. Top Lid

Overlap rails as shown and attach together with 5/16” x ¾” bin bolts.


E. Roof Vents

A. Goose Neck Vent Installation

1. Refer to the bulletin that comes with the vent for installation procedures

2. Locate Goose Neck Vent on the desired roof sheet. Typically slide Goose Neck Vent up the

roof sheet (Toward the small end) until the corners of the base intersect the roof sheet ribs.

3. Using the base as a template, mark and drill the 11/32” diameter mounting holes.

4. Apply (2) two beads of butyl sealant or mastic sealant as shown, between the Goose Neck

Vent base and roof sheet. Leave a 1” gap at the lower side of the outside bead.

5. Assemble Goose Neck Vent to roof sheet using 5/16” x 3/4” hex bin bolts and nuts. Tighten

all bolts and check sealant along upper end of Goose Neck vent base for any gaps or pockets.

Apply extra sealant as required.

6. Peen up edge on inside of Goose Neck Vent to make a water tight seal. The lip should be

approximately 1” all the way around.

7. Do Not Weld Goose neck vent to roof as rusting will result.


B. Low Profile Roof Vents

1. Install the Screen and clips on the roof vent body using 5/16” x 3/4” bin bolts, nuts and flat

washers as shown below. The bolt heads should be on the outside of the vent with the

washers and nuts on the inside (against the screen).

2. Locate the roof vent assembly on the roof panel (over the manhole) by aligning the holes in

the clips with the corresponding holes in the lower end of the roof panel.

3. Mark the outline of the roof vent with a marking pencil so that the vent can be returned to the

same position after the caulking is applied.

4. Remove the vent from the roof panel, turn upside down, and apply caulking to the mounting

surface of the sides and top.

5. At this time, install and tighten three 5/16” x 3/4” bin bolts and nuts in the holes directly

above and below the manhole (in the roof panel to prevent leakage).

6. Locate the roof vent on the roof panel in its original position and attach with the #14 x 3/4”

self-drilling screws provided. If a screw gun is not available, use the holes in the vent as a

guide and drill 3/8” holes through the vent and roof panel, and attach with 5/16” x 3/4” bin

bolts and nuts.

7. Install 5/16” x 3/4” bin bolts and nuts in the clips and bottom of screen as shown in detail on

previous page.

8. Tighten all bolts securely.

NOTE: Roofs with structural beams may require field installation of angles between beams at

both top and bottom of manhole opening if 20 PSF or 30 PSF live loading is required.


Section 5 –Temperature Cables

A. General Considerations

Follow temperature cable manufacturer’s recommendations for installation of temperature

cables. Be sure to allow adequate clearance for sweep augers or other internal equipment.

All temperature cables should be stabilized at floor level, to prevent cables from drifting out

towards the sidewall as bin is being filled. The use of light twine or monofilament line

double wrapped and secured to a recessed anchor, is a common practice.

Provide adequate sealant where temperature cable leads exit the bin.

Support of temperature cables by any means other than Chief Industries’ recommended

brackets may cause structural damage to the bin roof and will nullify the Chief Grain Bin

Warranty.

Note: Structured Roofs are designed for a maximum load of 2,000 lbs. per temperature cable. If this load is exceeded, this may cause structural damage to the bin roof and will nullify the Chief Grain Bin Warranty.

NOTE: All sheets must be installed with color code right side down as shown below. Check the

edges of the sheet for traces of the shop color code. The shop color code is always located on the

bottom edge of the sheet. The color codes and their corresponding gauges are listed in the table

below.



NOTE: Proper Bolting Sequence Must Be Followed At All Times.

(1) Tighten bolts in top 2 rings and top stiffeners.

(2) Select sheets of the proper gauge for the 3rd ring of the bin. Select proper gauge and

length of stiffeners.

(3) Install stiffener splice plates, to both ends of stiffeners with (2) 7/16” x 1-1/4” Bin

Bolts and whiz flange nuts per splice before securing the stiffener to the bin. Note: On

top stiffeners, splice plate is only required on the bottom end of the stiffener.

(3) Wipe excess oil from ends of the sheets and apply caulking as shown below

(4) Loosely assemble 3rd ring

(5) Loosely install stiffeners of the proper gauge to the exterior of the bin with 7/16” bin

bolts. Stiffener bolts are always placed with heads inside the bin. Using large

alignment punch, force stiffener up so that splices are tightly compressed. Tighten (4)

four bolts in 3rd ring to keep stiffeners compressed. Loosely install the (2) 7/16” x 1-

1/4” bolts connecting the stiffener splices to the stiffener splice plate above.


Note:

Blocks may be used to place under the stiffener splices to compress the stiffener splices.

Note:

Install bolts on sidewall sheets seam that are in the center of stiffener holes before installing

next stiffener.

(6) Lower the bin on to the foundation. This will force the 2 ring stiffeners in 2nd and 3rd

ring up to splices.

(7) Tighten stiffeners to sheets and stiffener splice to stiffener splice bolts.

(8) Tighten bolts in vertical seams in 3nd ring.

(9) Tighten bolts in horizontal seams between 2nd and 3rd ring beginning at center of sheet

and working both ways.

(10) Add ladder sections as required (See separate Ladder Manual)

(11) Repeat steps 1 thru 10 to add 4th ring and each additional ring. Proper bolting

sequence must be followed at all times to assure proper assembly.

NOTE: Use 7/16”x1 1/4” bin bolts at bottom sidelap of transition sheets. Use 5/16”x3/4” bin

bolts at the top sidelap at vertical seams of transition sheet.

NOTE: All bins have all 2 ring bottom stiffeners at the bottom, a 1 ring stiffener must be

placed at every other stiffener line in the 3rd ring.



B. Laminated Sheet Installation

(1). All rings, which require laminated sheets (indicated in the sheet and stiffener charts)

must be installed with the endlaps lapped as shown in the endlap detail below.

(2). Select the proper sheet gauge for each ring of the bin as indicated in the stiffener and

gauge chart.

Laminated Sheet Endlap

(3). Lap the bin sheets so that the outside ring of sheets follow this sequence: The right end of

each sheet is always on the outside of the bin and the left end is always on the inside

(looking from the outside). Refer to the endlap detail.

NOTE: This sequence is the same as the single sheet sequence.

(4). Lap the inner ring of the bin sheet so that they follow the same lapping sequence as the

outside ring of sheets. Refer to the endlap detail for lapping sequence.

(5). Follow the bolt installation procedure for bin sheet endlaps and sidelaps.

(6). Install stiffeners as outlined.


Caulking Detail on Laminated Sheets:

Apply caulking on endlaps as shown and along top horizontal seam in-between laminated sheets.


Note: Add neoprene washer in-between stiffeners and sidewall sheets on top stiffener hole on all

laminated sheets.


C. Base Angle Detail

(1) Bolt the base angle to the bottom of the bottom sheet as shown, with either 5/16” x 3/4“ with

a 3/8” flat washer between the whiz nut and the base angle or 7/16” bin bolts.

(2) Install base angle shims under all anchor brackets as shown.

(3) Seal base angle to concrete, using plastic cement or tar sealant. (NOTE: Sealant not supplied

by Chief Industries, Inc.)


Install Sealing Washers in-between bottom stiffeners and wall sheet on bottom two holes on

stiffener as shown.


D. One Ring Door

1. Place expandable foam around edges of frames as shown below.

2. Bolt the inner and outer frame to the bin sidewall with 7/16” x 3” bin bolts, making sure to

only place bolts in the holes shown in the detail below. The top eyebrow on the outer frame is to

be placed behind the sheet above the door. The bottom eyebrow is to be placed on the outside of

the sheet below the door. Bolt the inner and outer frames together with (10) 7/16 x 2” bin bolts

with whiz flange nuts.





E. Special Sidewall Sheets

On the Two-ring door there is an 81” short sheet to the left of the door and a special notched

sheet below the door. All sidewall sheets are installed on the outside of the doorframe, except the

walk door bottom sheet, which is installed behind the doorframe. (Note: when 5/16” bin bolts are

being used to install the door, install the 5/16” bin bolts with the nuts on the outside of the tank

where the door frame is bolted to the walk door bottom sheet all other bin bolts should be placed

with the head on the outside.) Special attention should be given to caulking around the doorframe

to insure a watertight seal.

On the Light Duty One-ring door there is an 81” short sheet, which is installed to the left of the

door, All sidewall sheets are installed on the outside of the doorframe, except for the sidewall

sheet directly below the door, which is installed behind the doorframe. Special attention should

be given to caulking around the doorframe to insure a watertight seal.

H. Light Bin Stiffener Anchor

All bins will have ALL 2 ring bottom stiffeners. Stiffened bins may have two or three Stiffeners

per sidewall sheet depending upon bin size and height.


Install Base Angle to bottom sheet of tank. Leave out bolts at stiffener locations.

Attach anchor to wall sheet as shown using center bolt hole. Place base angle shim under anchor.


Place Shim on top of anchor (Note: (2) shims come from factory spot welded together)

Attach bottom stiffener to wall and anchor using 7/16” bin bolts.

Place anchor channel over anchor bolt. Install square anchor washers over anchor bolt and place

nut on anchor bolt. Only finger tighten anchor bolts until bin is completely set down and

properly shimmed.


NOTE: Anchors placed over aeration trenches must be supported from the bottom of the trench.

If anchor bolt radius is not held, the bins warranty may be nullified.

All anchor bolts must project a minimum of 2” above the concrete floor. All anchor bolts, nuts

and washers shall conform to ASTM A307 (specification for carbon steel threaded standard

fasteners) unless otherwise noted. Anchor bolts and nuts are not provided by Chief Industries,

Inc.

I. Heavy Bin Stiffener Anchor

(1) All bins will have ALL 2 ring bottom stiffeners. Stiffened bins may have two or three

Stiffeners per sidewall sheet depending upon bin size and height.

(2) Bolt anchor brackets to 2-ring bottom stiffeners. DO NOT fully tighten, only finger

tighten at this time.

(3) After the bottom ring is attached, lower the bin carefully, placing all anchor brackets

over the anchor bolts.

(4) When full weight of the bin is on the concrete, shim the anchors as necessary by

sliding shim plates between the concrete and anchor bracket. All anchors must be

bearing upon the concrete or shimmed so that full bearing of the anchor is developed.

NOTE: Anchors placed over aeration trenches must be supported from the bottom of the

trench.

After all anchors brackets are shimmed snuggly, place two square washers over the

anchor bolts and tighten.

Plastic cement or tar sealant should be applied from inside the bin to seal the bottom ring

to concrete. (NOTE: Sealant is not furnished by Chief Industries, INC.)


Bin Stiffener anchors allow up to 3 anchor bolts to be used at each anchor location. There are (2)

1” diameter and (1) 1-1/2” diameter holes in each Bin Stiffener Anchor.

There are several different combinations that Chief Industries Recommends to anchor the bin to

the foundation.

1. One 1-1/4” x 12” anchor bolt may be used in the 1-1/2” diameter hole, if this is done the

anchor bolt must be pre set in the concrete

2. Two 3/4” x 12” anchor bolts may be used in the two 1” diameter holes. If this is done, at least

one of the two anchor bolts must be pre set in the concrete the second may be drilled in. (It is

recommended that both anchor bolts are pre-set.)

If anchor bolts are not pre set as stated above, and the anchor bolt radius is not held, the bins

warranty may be nullified.

Larger anchor bolts or the use of all three anchor bolts may be required if seismic conditions or

high wind loads exist. Chief Industries should be consulted for proper anchor bolts to be used.

All anchor bolts must project a minimum of 2” above the concrete floor.

All anchor bolts, nuts and washers shall conform to ASTM A307 (specification for carbon steel

threaded standard fasteners) unless otherwise noted. Anchor bolts, nuts and washers are not

provided by Chief Industries, Inc.

IMPORTANT: If expansion type anchor bolts are used to replace damaged anchor

bolts, the bolt radius circle must be checked at replacement locations so that the bin is

round when anchored. Chief Industries recommends using wedge anchors that meet

J. Transition Stiffeners

Aeration Trough Transition Stiffener Installations (for flush-floor aeration systems with two or

more fans)

(1) The formed concrete dimensions and the anchor bolt placement are important for the correct

installation of the transition stiffeners. When forming the concrete, the aeration troughs

should be located as specified in Chief’s aeration layout. The anchor bolt locations for the bin

need to be oriented to make sure that the number of anchors over the aeration trough is

minimized. When installing the anchor bolts, the bolt radius and bolt chord must be correct

and they must also be placed according to the details below.

IMPORTANT NOTE: Do NOT install the anchor bolts inside the aeration trench at this

time.

(2) When the bin is erected and located correctly (as illustrated above), insert the transition in the

aeration trough. Using the hole in the anchor bracket as a guide, drill a 3/4” hole through the

top of the transition. Slide the transition stiffener inside the transition and line it up with the

previously drilled hole. Loosely install the 5/8” x 1-1/2” A325 bolt. Rotate the transition

stiffener body so that it is centered under the bin wall anchor. See installation detail that

follows.

(3) The transition stiffener must be attached to the foundation with two (2) 5/8” x 6” expansion-

type anchor bolts. The holes for these anchor bolts should now be located. With an acetylene

torch, cut two holes in the bottom of the transition using the holes in the transition stiffener

base plate as guides. (This would mark the location of the anchor bolts in the concrete as

well.)

(4) Remove the transition stiffener and the transition.


Aeration Trough Transition Stiffener Installation Detail

(5) Locate the two anchor bolt locations (from cutting the holes in the bottom of the transition).

Set the transition stiffener over the locations to insure that the holes line up. Also, check to

insure that the transition stiffener is directly under and in line with the anchor. Make

adjustments if necessary. Drill the two holes for the 5/8” x 6” anchor bolts.

IMPORTANT NOTE: Do NOT install anchor bolts at this time.

(6) Enlarge the two holes in the bottom of the transition to 1” diameter.

(7) Reinstall the transition and slide the transition stiffener into position Loosely install the 5/8”

x 1-1/2” A325 bolt and rectangular washers at the anchor bracket location. The two 5/8” x 6”

expansion-type anchor bolts should now be installed and securely tightened the 5/8” bolts at

the anchor bracket. Caulking should be applied to seal the transition.

IMPORTANT NOTE: Transition stiffeners support the bin anchors. The transition must also

be supported inside the bin. See Chief’s aeration layout for supporting the transition.


K. Stiffener Upgrades for Goal Post (Optional)

When a goal post is being attached to bin, an extra layer of stiffeners are laminated over standard

stiffeners at goal post location from eave to base, as been is being erected.

Chief recommends that goal post be attached to the sidewall approx. 10’ below the eave of the

tank. (See separate goal post manual for attachment details)

Note: Listed below are the maximum loads that can be applied to upgraded stiffener columns.

16GA stiffener upgrade = 5,000 lbs. per column

14GA stiffener upgrade = 6,000 lbs. per column

2 stiffeners per sidewall


2 stiffeners per sidewall sheet

3 stiffeners per sidewall sheet




Section 8 – Wind Rings

A. Wind Rings

Consult the Chief catalog for the quantity of wind rings required for your bin. The quantity of

wind rings depends on the size of the bin and the application of any accessories (such as a

sidedraw system). For quantities and placement of wind rings required when a Sidedraw System

is installed on the bin, refer to the charts in this manual. The wind rings will be attached to the

sidewall using one bracket per stiffener spaced 58-5/16” apart (38-7/8” on 3 stiffened bins). The

brackets are specially formed and pre-punched to bolt directly to the sidewall stiffener holes. The

wind ring segments will be joined together using a bolted coupler.

NOTE: All wind ring segments are 248” long, and may need field cut to keep couplers in

between brackets.

(1) Working from outside the bin, determine the proper location for installation of the first wind

ring.

(2) Bolt the first wind ring bracket to the sidewall stiffener holes as shown in Detail below using

(2) of the stiffener attachment bolts and nuts with bolt heads on the inside. (Note: Wind ring

brackets may be installed below the endcaps if desired to allow for clearance of ladders and

platforms.)

(3) Move right to the next stiffener and repeat step 2.

(4) When 4 wind ring brackets have been installed, slide the first ring segment through the four

brackets leaving approximately 29 inches of the segment projection past the last bracket.

(5) Repeat step 2 through 3 until four more brackets have been installed.


(6) Slide the next wind ring segment through the four brackets and butt it firmly against the

previous segment.

(7) Connect pipes together with pipe coupler.

(8) Repeat steps 5 thru 7 until all wind rings have been installed.

(9) Pipes will need to be field cut to length to all the installation of the last wind ring.

(10) Check to see that all bolts in the complete wind ring are tight

Note: Some wind ring pipes may need field cut to allow coupler to land in-between

stiffeners.

Section 9 – Miscellaneous

A. Maintenance Instructions

ROOF: Annual inspection of the roof structure should be made to be sure there is

no holes in the roof panels and all connections are water tight. If leaks

should occur apply weatherproof caulk in the area of concern.

SIDEWALL: Sidewall inspection must also be conducted at least annually. Should leaks

occur apply caulk to area of concern.

Should spoilage occur, thoroughly clean surfaces. If oxidation is present,

remove oxidation and apply corrosive resistance paint.

BASE: Inspect base as often as possible for spoilage, as this is a direct indication

of excess moisture. If spoilage is present, thoroughly clean surface. If

oxidation is present, remove oxidation and apply corrosive resistance

paint. After paint has dried, apply base sealer to effected area.

DOORS: Inspect doors and manholes as often as possible to be sure proper seal is

maintained.

DECALS: Be sure all warning decals are installed in proper locations. Replace all

damaged or unreadable warning decals.
