Abstract

The invention relates to a cable safety protection device for a curtain wall and a daylighting roof with a cable structure, which is a safety protection device for a single-layer and monodirectional cable net structure in the glass curtain wall engineering and daylighting roof field. The structure comprises a pre-tightening bolt, an anchoring cartridge, a spring protective device, a steel pin shaft, a connecting ear plate, a body steel structure and a steel cable locknut, wherein, the anchoring cartridge comprises a left piece and a right piece and is fixedly connected with a vertical cable through a friction surface by the pre-tightening bolt; the vertical cable is connected with the body steel structure through the steel cable; the connecting ear plate is welded on the body steel structure; the structure of the spring protective device comprises a movable end connecting rod, a spring, a spring press block, a spring protective sleeve and a fixed end connecting rod; the movable end connecting rod and the fixed end connecting rod at two ends of the spring protective device are respectively connected with the anchoring cartridge and the connecting ear plate through the steel pin shaft; one end of the movable end connecting rod is connected with the spring press block through screw threads; the fixed end connecting rod is screwed in the spring protective sleeve by screw threads.

Description

technical field [0001] The cable structure curtain wall and daylighting roof cable safety protection device of the present invention relates to a cable safety protection device supported by a single-layer, unidirectional cable structure, which is applicable to the fields of glass curtain wall engineering and glass daylighting roof engineering. Background technique [0002] At present, single-layer, one-way cable net structure supporting glass curtain wall and glass daylighting roof have been gradually applied in the exterior decoration of modern buildings. Single-layer, one-way cable net structure supports glass curtain wall and glass skylight. High-strength pre-tensioned steel strands are used as the load-supporting structure of curtain wall or skylight. , The building facade is simple and other advantages, especially the one-way cable structure supporting the curtain wall. Therefore, this type of curtain wall and skylight is favored by owners and architects. However, due...

AI Technical Summary

Problems solved by technology

In addition, the single-layer and one-way cable net structure adopts the form of a single member, which is a statically indeterminate structure, without redundant constraints and members, and the cross-sectional area of ​​the cable members is usually small. High areas, so when rare earthquakes occur, the probability of component damage is greater

In addition, due to the process, equipment and other reasons of the pressure pipe joints of the cable components, micro-cracks invisible to the naked eye will occur in the joints during the pressing process, forming a safety hazard

Although the material strength of the cable components is high and the material safety factor is large, due to the existence of the aforementioned factors, the damage of the single-layer, one-way cable structure supporting the curtain wall and the lighting roof components, especially the vertical pull of the curtain wall's own weight The damage of the cable components and the cable components of the skylight may cause the glass plate to fall off at a high level, resulting in serious casualties, thus limiting the scope of use of this type of structural curtain wall and reducing the safety of the curtain wall and skylight structure
