Curtain wall connecting structure with unaligned roof and floor deformation joint

Abstract

The invention relates to a curtain wall connecting structure with an unaligned roof and a floor deformation joint. The curtain wall connecting structure comprises a curtain wall arranged on a main building structure, wherein a curtain wall deformation joint is reserved at the place where the curtain wall corresponds to the floor deformation joint, and the width of the curtain wall deformation joint is consistent with that of the main building structure; a curtain wall deformation joint is reserved at the place where the curtain wall corresponds to a roof deformation joint, and the width of the curtain wall deformation joint is not less than the maximum inter-story displacement of the main building structure; the roof is connected with a roof support ear plate which is movably connected with a connecting plate; the curtain wall is connected with a curtain wall support ear plate which is movably connected with a connecting plate; the connecting plates are movably connected mutually by a stay bar. The invention can prevent the curtain wall system from being destroyed due to the vertical deformation of the roof, and can also prevent the curtain wall unit between the roof and the floor deformation joint from being destroyed due to the inconsistent deformation of the main structure unit on both sides of the deformation joint.

Description

(1) Technical field [0001] The invention belongs to the connection structure between a building exterior curtain wall system and a main structure. It is especially suitable for curtain wall systems where the scale and span of buildings such as railway passenger station buildings, airport terminals, and exhibition centers are large, and the deformation joints between the roof and the floor are not aligned. (2) Technical background [0002] For structures with large spans such as railway station buildings, airport terminal buildings, and convention and exhibition centers, the span of the floor load-bearing structure is much smaller than that of the light steel roof. In order to save costs and avoid excessive overhangs, deformation joints of the roof structure usually need to be set In the center of the column bay, it is not aligned with the deformation joint of the floor structure. For this kind of building, only one curtain wall deformation joint is set at the deformation jo...

AI Technical Summary

Problems solved by technology

because , the in-plane deformation capacity of the curtain wall is difficult to meet the requirements, and it is very easy to cause extrusion deformation in the curtain wall surface, which in turn leads to the separation of the glue joint between the glass panel and the frame or the collision and bursting of the glass panel and the point-supported support
