Framework glass curtain wall arborescent supporting vertical frame

Abstract

The invention provides a tree-like support mullion for a frame glass curtain wall, which solves the problems of the existing equal-section profile mullion, such as waste of material, small pre-tensioning force of the mullion, single shape, and poor visual effect. The supporting mullions, the technical points are: the supporting mullions are composed of a variable-section main mullion and two variable-section secondary mullions symmetrically supported obliquely in the middle of the variable-section main The frame is a T-shaped frame welded by the constant-section profile as the top plate and the variable-section profile as the web, and the variable-section secondary mullion is a frame welded by the variable-section profile as the support plate and the semicircular steel pipe as the reinforcement. Since the cross-sections of the above-mentioned variable-section main and secondary mullions change with different stress-bearing parts, their structural design is reasonable. The anti-destabilization ability and anti-deformation ability of the frame increase the appearance beauty of the curtain wall.

Description

technical field [0001] The present invention relates to a support structure for frame glass curtain wall, in particular to a large-span tree-shaped support mullion for frame glass curtain wall, which is mainly suitable for supporting the back of various large-span interlayer curtain walls, and belongs to frame glass curtain wall support technology field. Background technique [0002] At present, the method of curtain wall mullions adopts the method of hanging metal profiles with equal cross-sections on the outside of the civil structure. If there is a large room, the mullion can only be supported by double supports within the height range of the side beams of the civil structure to achieve reduction. The mullion section and the purpose of reducing mullion deformation, but these methods have at least the following deficiencies: 1. Since the material is selected as a profile mullion, its cross-section is equal everywhere, so in many sections within the entire length of the mul...

Problems solved by technology

[0003] The object of the present invention is to provide a tree-shaped support mullion for frame glass curtain wall, which solves the problems of waste material, small pre-tension force, single shape and poor visual effect of the existing equal-section profile mullion. Reasonable, the variable cross-section frame gives full play to the mechanical properties of the material, saves material, significantly improves the anti-instability and anti-deformation capabilities of the supporting mullion, and increases the appearance of the curtain wall
