A curtain wall beam-column connection structure and construction method

Abstract

The invention provides a curtain wall beam-column connection structure and a construction method, belonging to the field of curtain wall joists. It solves the problems of poor stability, poor versatility, inconvenient construction and poor safety of the existing curtain wall beam-column connection structure. The beam-column connection structure of the curtain wall includes a column and a beam. Pin holes are provided on the side wall of the column. An adapter is fixed at the end of the beam. The pin sleeve and adjusting sleeve; also includes the adjusting rod embedded in the adjusting sleeve; also includes the latch embedded in the pin sleeve, the inner end of the latch is fixed with a slide bar, the inner wall of the pin sleeve is provided with a reset groove, and the wall of the latch rod is provided with a reset The bolt is covered with a return spring two; the wall of the pin hole hole is provided with a card hole, the wall of the outer end of the bolt is fixed with a card block, the adapter is provided with an inner positioning block, and the outer end of the adjustment rod is fixed with an inner alignment block. The connection structure has stable structure, strong versatility, convenient construction and high safety.

Description

technical field [0001] The invention belongs to the technical field of curtain wall joists, and relates to a curtain wall beam-column connection structure and a construction method. Background technique [0002] When the column and the beam of the existing closed profile are connected, the connecting head with the spring pin is usually fixed on the end of the beam, and the spring pin is used to cooperate with the pin hole on the column. This structure has the disadvantage of inconvenient installation and cannot be disassembled. [0003] The existing application number is 201410136367.6, which is a Chinese invention patent named "Thread Drive Pin Type Curtain Wall Beam Connection System". Relatively fixed, so that the slider and the pin move simultaneously by rotating the bolt, so that the pin penetrates into the pin hole of the column to connect the beam and the column. Although it overcomes the defects of inconvenient installation and inability to disassemble existing in t...

AI Technical Summary

Problems solved by technology

Although it overcomes the defects of inconvenient installation and inability to disassemble existing in traditional spring pins, it still has the following problems:

[0004] 1. The pin can only penetrate the pin hole, but cannot be completely fixed with the pin hole, so that the beam cannot be completely fixed with the column. In order to stabilize the fixation, other structures are usually required to fix it, so the stability is poor;

[0005] 2. This structure can only be used for beams with convex-shaped protruding spaces, but not for beams of other structures, so the versatility is poor;

[0006] 3. The structure needs to be operated between the gap between the beam and the column, and the bolts need to be rotated parallel to the direction of the beam, so the construction is inconvenient;

[0007] 4. Bolts can be driven to rotate using ordinary tools, so the safety is poor
