1243226 V. Description of the invention (4)

Zhizhi can be divided into three types: metal curtain wall, P.C. curtain wall, and glass curtain wall. The main materials of metal curtain wall are: Ming material (the largest amount is used), 2 · steel material, 3. enamel plate material, 4 · stainless steel material, etc. Metal curtain wall can be roughly divided into straight frame system (MULLION TYPE), skirt system (SPANDREL TYPE), panel system (PANEL τγρΕ) and composite system according to its construction method and assembly type.預鑄 Concrete The structure of the curtain wall, whose main body is concrete, steel, barbed wire, etc., is placed in a pre-assembled frame mold, and after appropriate curing, it is demoulded and then placed on the building structure. The glass curtain wall is composed of a large area of glass and suspended installation. The glass is generally made by the production method of float precession plate glass, so the glass M used in the curtain wall is commonly known as floating glass. If the float glass is annealed, quenched, and fired ij, strengthened glass with high bending strength can be obtained. In addition, the heat-absorbing effect of MS glass can also be made into heat-absorbing glass and reflective glass. ^ f t construction of women's clothing needs to pay attention to whether the installation surface is accurate, and the anti-spinning effect of wind pressure is good, most of them are based on installation and construction. When sighing this leaf, you need to know if there are any unreasonable construction conditions.

Latitude m, ^ 1 ^ failure cases of curtain walls all occur in design considerations, and there are not many factors in the design. When k is a barrier, it is imperative that perfect design and accurate storage of curtain walls are indispensable. The performance of the above-mentioned external walls of the Jianye and the installation and construction openings are the same as those of the external doors of the Jianye, and the environmental control performance is required; t is the same as when designing the present invention.
