EXPERIMENTAL STUDY ON COMPOSING SANDWICH CURTAIN WALL

Abstract

In the previous report (1), a new method of composing Sandwich Curtain Wall is proposed. The Curtain Walls are made in the following way. 1. Steel-bar-grid is attached to the structural frame. 2. This grid is sandwiched between two special concrete plates. 3. These two are combined by concrete set between them. This experimental study is conducted on composing the Sandwich Curtain Wall under the following two cases. 1. Both sides of Sandwich Curtain Wall are composed by special concrete panels. These panels are made in our laboratory. 2. One side of Sandwich Curtain wall is composed by special concrete panels and the other sideis composed by tile panels and wood panels. The tile panels are used at the under half of the side and the wood panelsare used at the upper half of it. The results obtained are as follows : 1. The weight of a panel is only 6.1〜6.7kg. 2. Process of making each panel is simple and it is fitted mass production. 3. According to this method of composing Sandwich Curtain Wall, panels can be connected firmly and set precisely in its position. 4. The work of seting panels can be done even by one person. 5. This method of composing Sandwich Curtain Wall is easy, exact and rapid. 6. In this experiment the length of steel bars attached to the structural frame were 1.81m. This method is however practicable with in the steel bar length of 3m.
