Large decorative strip second fulcrum connection system and its installation method

Abstract

The invention discloses a second supporting point connecting system of a big decorative strip and an installation method of the second supporting point connecting system. The connecting system comprises a structure steel beam fixed on a main body structure; the outside of the structure steel beam is welded and fixed with a flat panel, and the flat panel is provided with a vertical through slot; the side face of the through slot faced to the structure steel beam is welded with a halfen slot, and the opening of the halfen is aligned to the through slot; a gliding T-shaped bolt is arranged in thehalfen; the outside face of the flat panel is provided with a horizontal connecting cross beam, and the side face of the connecting cross beam is fixedly connected with the flat panel through an L-type adaptor; the adaptor is provided with a first side face and a second side face which are perpendicular to each other; the first side face is fixedly connected with the flat panel through the T-shaped bolt and the second side face is fixedly connected with the connection cross beam through a fixing bolt. The second supporting point connecting system can avoid massive welding on site and realizeadjustable third-dimension; thus the installing quality can be effectively controlled, the safety hidden trouble is eliminated, the ability of absorbing structure bias is strengthened, and the damageto a finished product is reduced.

Description

technical field [0001] The invention belongs to the technical field of building curtain walls, in particular to a second fulcrum connection system of a large decorative strip and an installation method thereof. Background technique [0002] The existing method of installing the second fulcrum of the large decorative strip is that the adapter is directly installed on the main structure by welding. This technology has the following disadvantages: [0003] 1. A large number of welding methods are used on site, and the welding quality is difficult to control. During welding, due to the narrow operating space and overhead welding, the technical level of the workers is high, and the welding quality is difficult to control. The decorative strips are larger and the lateral force is larger, which poses a greater safety hazard. [0004] 2. It is not conducive to the protection of finished products. A large number of welding is used on site, and the installation gap is small. The ins...

AI Technical Summary

Problems solved by technology

[0003] 1. A large number of welding methods are used on site, and the welding quality is difficult to control

During welding, due to the narrow operating space and overhead welding, the technical level of the workers is high, and the welding quality is difficult to control, while the decorative strip has a large overhang and a large lateral force, which poses a large safety hazard

[0004] 2. It is not conducive to the protection of finished products

A large number of welding is used on site, and the installation gap is small. The installed aluminum and glass are easily burned, causing irreparable damage

[0005] 3. High installation accuracy requirements

After the welding is completed, the left and right cannot be adjusted, so the requirements for the positioning of steel parts are relatively high
