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

Abstract

The invention discloses a non-welded base steel frame for indoor curtain wall decoration, which includes a horizontal keel and a vertical keel as the keel base steel frame, and at least one keel bar is respectively arranged on the horizontal keel and the vertical keel along the axial direction There are anchor bolts set in the keel bar holes, and elastic pressure plates are set on the threaded ends of the anchor bolts to fix the horizontal keel and vertical keel on the indoor structure wall in a detachable manner; avoiding a large number of electric welding operations during the installation of the base steel skeleton The problem is that the connection between the keel base steel frame and its special accessories and fasteners is compared with the traditional electric welding steel frame system. The special accessories are finalized, standardized and industrialized to ensure the quality of the project and avoid welding. fire hazard. Adopting the base steel frame of the present invention can effectively shorten the construction period, greatly improve the installation quality, effectively reduce potential safety hazards on site, and ensure safe and civilized construction on site.

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
