Non-welded base layer steel frame for indoor curtain wall decoration

Abstract

The invention discloses a non-welded base layer steel frame for indoor curtain wall decoration. The non-welded base layer steel frame comprises a transverse keel and a vertical keel which serve as a keel base layer steel frame body. At least one keel strip hole is formed in each of the transverse keel and the vertical keel in the axial direction. Anchor bolts are mounted in the keel strip holes ina sleeved mode. Elastic pressing plates are mounted at the threaded ends of the anchor bolts in a sleeving mode and fix the transverse keel and the vertical keel to an indoor structure wall in a detachable mode. The problem of a great quantity of electric welding operation in the mounting process of the base layer steel frame is avoided. Compared with a traditional electric welding type steel frame system, according to the connecting mode between the keel base layer steel frame body, special accessories of the keel base layer steel frame body and fasteners, the project quality is ensured through forming, standardization and industrialization of the special accessories, and free welding avoids fire hazards. By adopting the non-welded base layer steel frame for indoor curtain wall decoration, the construction period can be effectively shortened, the mounting quality is greatly improved, potential safety hazards on a site are effectively reduced, and safe and civilized construction on the site is ensured.

Description

technical field [0001] The invention relates to the technical field of building curtain wall engineering, in particular to a non-welded base steel frame for indoor curtain wall decoration. Background technique [0002] For a long time, the basic steel frame of building curtain wall decoration basically adopts welding process. The traditional welded dry-hanging steel frame system contains a large amount of steel, the material is heavy, and the installation is cumbersome. It needs to be welded and fixed, and it is easy to cause heat and deformation of the steel frame. Local damage to the galvanized layer affects the overall flatness and aesthetics. Welding will leave weld scars on the steel frame, and the weld scars need to be treated with slag removal and anti-rust treatment in the later stage. Improper treatment will easily oxidize and rust and affect the life of the steel frame. At the same time, the biggest defect of electric welding connection is that it is easy to produ...

Problems solved by technology

[0002] For a long time, the basic steel frame of building curtain wall decoration basically adopts welding process. The traditional welded dry-hanging steel frame system contains a large amount of steel, the material is heavy, and the installation is cumbersome. It needs to be welded and fixed, and it is easy to cause heat and deformation of the steel frame. Local damage to the galvanized layer affects the overall flatness and aesthetics

Welding will leave weld scars on the steel frame, and the weld scars need to be treated with slag removal and anti-rust treatment in the later stage. Improper treatment will easily oxidize and rust and affect the life of the steel frame

At the same time, the biggest defect of electric welding connection is that it is easy to produce false welding, causing the steel frame system to bury safety hazards

The construction site of electric welding is full of sparks, smog, and welding slag, which requires professional equipment and auxiliary equipment. The energy consumption is relatively large, and there is a fatal hidden danger of electric welding itself, namely fire.

Through the summary analysis of the traditional welded steel frame, it can be seen that the existing welded steel frame has the following shortcomings: ① electric welding itself has a fatal hidden danger, that is, fire; ② on-site electric welding processing, high management costs, and easy waste of materials; ③ Welding is easy to weld, and improper post-processing is easy to oxidize and rust, and will cause damage to steel; ④ The shortage of welders will directly restrict the progress of the construction period; ⑤ High energy consumption, smoke affects the construction environment, and professional equipment and auxiliary equipment are required
