INTRODUCTIONThe details in this handbook are a compilation of erection and bracing details that are issuedwith the roof layout supplied by the Prefabricated Timber Truss Fabricator as part of the sitedocumentation or incorporated in the workshop drawings. These details cover nearly all thestandard aspects of erecting and bracing all categories of timber roofs.

Alternative details may be issued by the design engineer, in which case these detailsoverride those published in this book for the particular structure that they have beendesigned for.

All trusses and all bracing requirements must be shown on the roof plan supplied by the truss

manufacturer.

Prevailing conditions must be considered where it may be necessary for the specification ofcorrosion proofed nails for securing of metal bracing strap, metal connectors, hangers andfixing of timber members.

The Magisterial districts or towns specified for treatment of sawn timber as published inSANS 10005:1994 (SABS 05:1994) could be used as a guideline for use of corrosion proofednails where doubt exists.

Note: All metal bracing, hangers, clips and the like must be fixed strictly in accordance withthe manufacturers instructions.

FOREWORD

ITC-SA gives recognition to engineers with substantial experience and provencompetence in timber engineering by accepting them as Engineer members.In order to ensure full compliance with all the provisions of both the NationalBuilding Regulations & Building Standards Act [Section 14 (2A)] and NationalBuilding Regulations [Clause A19]. These engineers may appoint, train andregularly re-train Inspectors to inspect erected Timber Roof Structures on

their behalf.

Engineer

to:Raise standards in the Nail Plated Timber Roof Truss Industry t h r o u g hthe development and supportive enforcement of appropriate technical,quality and ethical standards.Monitor adherence by ITC-SA members of relevant industry relatedstandards, SANS specifications and Codes of Practice and in so doing actas a protector of consumer interests.Foster and promote all ITC-SA members interests through appropriateadvertising and publicity by facilitating training and lobbying at all relevantlevels and forums.

The Institute for Timber Construction South Africa's - ITC-SA's - mission is

The ITC-SA Engineering Systems who are members of the ITC-SA, namelyAlpine Automation South Africa (Pty) Ltd, International Truss Systems (Pty) Ltd,MiTek Industries S.A. (Pty) Ltd, and 2009 Multinail Africa (Pty) Ltd, have alldeveloped computer software capable of designing timber roof structures incompliance with the relevant design codes of practise. The Systems ensurecompetent use of their design software through training of their licensedFabricators. The Systems also manufacture and supply the connector nail-plates and other necessary brackets and hardware upon which the softwaredesign criteria is based.


5/101

Fabricators/Truss Plants are licensed by the Engineering Systems to designand manufacture pre-fabricated, mono-planar nail-plated roof structures. Theyare audited by the ITC-SA on an annual basis to ensure compliance withITC-SA requirements and the National Building Regulations and to achieve aCertificate of Compliance for Truss Manufacture.

To further assist in developing the standards within the industry, ITC-SApresents a duel level estimator/designer course which upgrades the quality and

competency of personnel in truss plants.

ITC-SA approves Erectors who have undergone work evaluations and trainingin order to achieve a Certificate of Competence for Erectors. Of particular

relevance is their understanding and correct application of the bracing rules ascontained in the Roof Erector's Handbooks Volumes 1 & 2, which arecontinuously re-evaluated and updated through ITC-SA facilitation. Thesebracing details have been included in SANS10243 (The Manufacture andErection of Timber Trusses) and some are also included in SANS 10400 The

Application of the National Building Regulations- part L.

ITC-SA approved Engineers appoint and train Inspectors to inspect roofstructures. The Engineers accept responsibility for the design and structuralstability of the roofs after inspection and approval of the roofs by the Inspectors.This process is in compliance with Regulation A19 of the National BuildingRegulations, which then enables the home owner to obtain an occupancycertificate from the local authority.

= LESS THAN 3 MM OFF CENTRE.

TOLERANCE IS CRITICAL FOR BOTH A GOOD ROOF LINE AND EFFECTIVE BRACING.

A GUTLINE, PLUMBLINE OR LEVEL SHOULD BE USED.

1. TRUSSES TO BE ERECTED WITH OVERALL BOW IN ITS TOTAL RAFTER LENGTH LESS THAN

L/200 AND LESS THAN 50MM (L = CHORD LENGTH). THE BOW BETWEEN BATTENS OR

PURLINS MUST BE LESS THAN Lp/100 (Lp = BATTEN/PURLIN SPACING).

2. TRUSSES TO BE ERECTED WITH APEX NOT MORE THAN THE LESSER OF SPAN/200 OR

HEIGHT/50 FROM A VERTICAL PLANE THROUGH ITS SUPPORTS.

3. AT ANY SECTION, THE LOCAL OUT OF PLUMB SHOULD NOT EXCEED HEIGHT/50 OR 50MM.

WHICHEVER IS THE LESSER.

GENERALLY, IF A BOW OR TILT IS EVIDENT TO THE EYE, THE TRUSS HAS PROBABLY BEEN

ERECTED OUTSIDE THE TOLERANCES.
