Construction method of beam and column connection structure in glass curtain wall

Abstract

The invention discloses a connection structure between a beam and a column in a glass curtain wall and a construction method thereof. The connecting piece is inserted into the frame slot at the front end of the crossbeam, the horizontal positioning screw is fixed to the column through the screw hole and the connecting hole, and the longitudinal connecting screw is fixed to the crossbeam through the fixing hole; it also includes A rear-end positioning screw arranged perpendicular to the outer wall of the column, a limiting groove is provided on the rear side wall of the beam, and the rear-end positioning screw is connected to the column through the limiting groove and the positioning hole. In the present invention, the front end of the cross beam is connected to the cross bar and the upright column by means of screw insertion by the connecting piece, which is more convenient to connect and easy to disassemble and adjust. Prevent the beam from turning over, improve the installation accuracy and the aesthetics of the exterior wall.

Description

technical field [0001] The invention relates to the technical field of a glass curtain wall, in particular to a construction method for a connecting structure of a beam and a column in a glass curtain wall. Background technique [0002] Glass curtain wall is a kind of beautiful and novel building wall decoration method, and it is a remarkable feature in the era of modernism high-rise buildings. Usually, the glass curtain wall includes columns, beams and glass panels, and the glass panels are installed on the frame structure constructed by the columns and beams through an attached frame. [0003] When building a frame structure, the connection structure between the beam and the column is divided into two types: one uses an aluminum alloy corner bracket, installs a corner bracket on the beam, and fixes the corner bracket on the beam to the column by means of screws; the other The first adopts a combination of plug-in and spring pins. The plug-in is fixed on the side of the be...

Problems solved by technology

[0004] For the former, the open profile must be used to meet the installation requirements of the beam, but the torsion resistance of the open profile is weak. If the torsion resistance of the open profile is to be ensured, the section size of the profile must be increased, which will cause waste of materials and increase costs; the latter , although closed profiles can be used, the connection method of the spring pins requires relatively high processing accuracy of the profiles. Relying on the elastic force to insert into the pin holes on the column to form a connection, it is impossible to judge whether all the pins are in place during the installation process, so there are potential safety hazards. At the same time, this connection method is difficult to disassemble once connected, and has the disadvantage of inconvenient maintenance

In addition, due to the bending moment generated by the self-weight of the glass panel, the beam always has a tendency to tilt outward, and the spring pin is installed in the cavity at the back of the beam, away from the glass panel, causing the beam to always turn over, affecting the connection of the spring pin way of mounting accuracy
