Large-area curtain wall keel structure and installation method thereof

Abstract

The invention relates to a large-area curtain wall keel structure and a mounting method thereof, and relates to the field of building steel structure construction technologies. Comprising a plurality of cylindrical stand columns and a plurality of vertical unit frames, the stand columns are used for integrally fixing the vertical main keels through the metal embedded parts, and the vertical unit frames are used for integrally fixing the vertical main keels through the metal embedded parts. Adjusting holes matched with the stand columns are formed in the vertical unit frames in the length direction of the vertical unit frames, and the stand columns are arranged in the adjusting holes in a penetrating mode and connected with the vertical unit frames in a sliding mode. According to the curtain wall unit installation structure, the vertical unit frame arranged on the stand column in the rotating and sleeving mode can make circumferential deflection of the vertical unit frame more suitable for installation of the curtain wall unit, the situation that the curtain wall unit is violently installed in the installation process is reduced, and meanwhile the adaptation degree between the vertical main keel and the curtain wall unit is improved; the situation that when the vertical main keel is installed, the installation gap is large when the curtain wall is installed due to the circumferential deflection error is reduced.

Description

technical field [0001] The present application relates to the field of building steel structure construction technology, in particular to a large-area curtain wall keel structure and an installation method thereof. Background technique [0002] In the practice of large venues, theaters and other buildings, in order to increase the overall sense and beauty, a large area of ​​curtain wall is often designed and installed on the outer wall of the building. The curtain wall structure generally includes vertical main keels fixed on the outer wall of the building and horizontal fixing The secondary keel between the main keels, wherein in order to facilitate the installation of the curtain wall unit, the two sides of the main keel are usually vertical plane structures. Multiple curtain wall units will be neatly arranged and installed on the keel structure to form the whole curtain wall. [0003] In the related art, metal components are generally embedded at the fixed position of th...

AI Technical Summary

Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor found that when installing the vertical keel, during the welding process, it is inevitable that installation errors will occur due to welding deformation, resulting in deflection of the circumferential fixed angle of the main keel

When the deflection angle caused by the error is large, it will hinder the installation of the curtain wall unit, or cause the installation gap between the curtain wall unit and the keel structure to be too large, especially when the curved curtain wall is installed, the main keel will appear circumferential Deflection has a particularly severe effect on the installation of curtain wall units
