CONSTRUCTIONDETAILS

Mediatheque Centre, SendaiArchitects: Toyo Ito & Associates, Tokyo

It conceive a piece of townscape, with its

transparent main façade, its free layout and

the clear stratification of the various floor

levels lend the building a quality of

permeability and openess.

The media centre houses a number of civic

amenities, including library, two galleries, an

information centre for the disabled, and a

multimedia library with an ancillary cinema,

as well as seminar rooms and a café.

Façade The glazed double skin extends up over the edges of the structural

floor slabs. The outer skin consist of clear or translucent glazing and opaque

aluminium panels. Some area such as staircase is laid out in a series of straight

flights and screened by a layer of vertical metal strips. The open, grid-like

coverings over the service structures on the roof are conceived as a fifth façade.

Glazed Double Skin Facade

University in SaitamaArchitects: Riken Yamamoto & Field Shop,

Yokohama

Situated outside on the outskirts of Tokyo, surrounded by housing

development and paddy field. It consist of seminar spaces beneath a

landscape deck, and the platform, in which the series of courtyard are

created, is flanked by two building tracts laid out parallel to each other.

Access to these tracts, which contains seminar rooms and laboratories,

is via four –storey galleries that open to the landscape platform through

finely articulated glazed façade. The rear-trussed construction of the

transparent skin consist of horizontal flat-steel members with vertical

tensioning rods. The façade of the building are attached with horizontal

aluminium sun shading louvers.

Typical effects of wind pressures

around buildings Wind load is part of the

consideration in the building construction where it

will be more important for the higher building.

The building consist of storey high glazing elements – transparent on the ground floor and translucent in the upper

levels. The walls, columns and exposed ribbed metal soffits of the floor slab are painted white, with the dark

parquet flooring striking a contrasting note. The strict axial grid of the load bearing structure allowed the dimensions

of the ground columns to be kept to the minimum. The building has a steel structure, the floors of which are

suspended from bracket fixed to the façade columns. As a result of this, the floors are not immediately visible from

the street. Their lines are merely indicated by the narrow fixing strips to the storey height façade glazing.

views of the construction method. Steel structures tend to

shrink and expand in respond to the changes of temperature.

Thus, there should be a little gap between end of the steel

joints.

3D Railing construction details Installed at

the edge of the concrete slab, which main part of the

railing, made of steel, is bolted to the concrete slab through

steel plate. Glass panels of the railing are clamped to the

steel structure.
