Folding fan-shaped hyperboloidal unit-type building curtain wall system and a construction method thereof

Abstract

The invention provides a construction method for forming a folding fan-shaped hyperboloidal unit-type building curtain wall by fitting plane unit body plates. The method mainly comprises the following steps of: dividing a hyperboloidal curtain wall into a plurality of units; performing a conversion of plane unit bodies on full curtain wall unit bodies; manufacturing unit bodies according to the converted plane unit bodies; and installing the unit bodies in a curtain wall structural system to form a curved surface by a cold twisting method. By using the construction method, complex processes for manufacturing panel unit bodies of the curved surface are avoided; and the plate unit bodies are molded into a hyperboloidal unit body in a structural system by cold twisting in installation, so that the defects of clear edges and corners and undesirable curved surface effect caused by forming the hyperboloidal curtain wall by using plate unit bodies in the prior art are overcome. The curved surface intent of the folding fan-shaped hyperboloidal unit-type building curtain wall of an architect is fully shown; and the guarantee of a method and a structure is provided. The invention also discloses the folding fan-shaped hyperboloidal unit-type building curtain wall system.

Description

technical field [0001] The invention belongs to the field of construction, and relates to a construction method for realizing a curved building curtain wall, in particular to a construction method for forming a fan-shaped hyperboloid unit curtain wall by fitting plane unit body plates (by cold bending on site), and also relates to The fan-folding hyperboloid unit type building curtain wall system. Background technique [0002] In the prior art, when the construction of the curved curtain wall of the building is involved, the following methods are generally considered to realize the curved surface: the glass hot bending method and the polyline fitting method. [0003] The glass hot bending method is to bend the unit glass under high temperature conditions in the factory to form the shape required for the curved curtain wall, and at the same time, the aluminum alloy keel or steel keel is also bent into a corresponding arc shape, and the above parts are processed into an arc sh...

AI Technical Summary

Problems solved by technology

The advantage is that the overall appearance of the curved surface of the curtain wall is smooth and beautiful. The disadvantage is that the hot bending treatment of the glass increases the cost a lot, especially when hollow, laminated or hollow laminated glass is used, the cost increases more. If the curved surface is complex and irregular , which will greatly increase the cost and difficulty

Its complex and irregular glass curtain wall surface requires a hot bending mold for each curved glass plate of the unit body. The amount of mold used is large and the cost is high, which is obvious

[0004] The broken line fitting method is to use flat glass units to fit the curved surface of the curtain wall. The cost is not high, but the surface effect is not ideal. The curved curtain wall produced has sharp edges and corners, and the curved surface effect is not ideal.

If you are making a hyperboloid curtain wall, sometimes you need to divide the plate into triangles. In addition, it is very difficult to waterproof the flat unit between the units.
