Beam and column connection structure in glass curtain wall and construction method thereof

Abstract

The invention discloses a beam and column connection structure in a glass curtain wall and a construction method thereof. The beam and column connection structure is characterized by comprising a connecting piece at the position where a beam and a column are connected, transverse locating screws and longitudinal connecting screws, wherein the transverse locating screws and the longitudinal connecting screws are used for fixing the connecting piece. The connecting piece is inserted into an auxiliary frame insertion groove at the front end of the beam. The transverse locating screws are fixed with the column through screw holes and connecting holes. The longitudinal connecting screws are fixed with the beam through fixing holes. The beam and column connection structure further comprises a back end locating screw perpendicular to an outer wall of the column. A back side wall of the beam is provided with a limit groove. The back end locating screw is connected with the column through the limit groove and locating holes. The front end of the beam is connected with a cross rod and the column through the connecting piece in an screw inserting mode. The beam, the cross rod and the column can be connected conveniently and are easily to be dismantled and adjusted. The back end of the beam is connected with the column through the back end locating screw, the vertical position is limited by the limit groove to prevent the beam from overturning, and the installing precision and aesthetics of the outer wall are improved.

Description

technical field [0001] The invention relates to the technical field of a glass curtain wall, in particular to a connection structure of a beam and a column in a glass curtain wall and a construction method thereof. 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 o...

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
