CONSTRUCTIONDETAILS

Mediatheque Centre, Sendai

Architects: 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 Saitama

Architects: 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.

High building

Low building

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.

Low and high buildings

Furniture Store in Tokyo

Architects : Kazuyo Sejima & Associates, Tokyo 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.

3D floor sectional floor construction Another 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.
