Curtain wall beam-column connecting structure, construction tools and construction method

Abstract

The invention provides a curtain wall beam-column connecting structure, construction tools and a construction method, and belongs to the field of curtain wall keels. The problems that an existing curtain wall beam-column connecting structure is poor in stability, poor in universality, inconvenient to construct and poor in safety are solved. The curtain wall beam-column connecting structure comprises a stand column and a cross beam, a pin hole is formed in the side wall of the stand column, an adapter is fixed to the end of the cross beam, a plug pin is arranged on the adapter, an adjusting mechanism is arranged on the adapter, and the adjusting mechanism comprises a pin sleeve, an adjusting sleeve, an adjusting rod and a plug pin, wherein the pin sleeve and the adjusting sleeve are fixed to the adapter; the adjusting rod is embedded in the adjusting sleeve; the plug pin is embedded in the pin sleeve, a sliding rod is fixed to the inner end of the plug pin, a reset groove is formed in the inner wall of the pin sleeve, a reset block is arranged on the rod wall of the plug pin, and the plug pin is sleeved with a second reset spring; and a clamping hole is formed in the hole wall of the pin hole, a clamping block is fixed to the rod wall of the outer end of the plug pin, an inner positioning block is arranged on the adapter, and an inner alignment block is fixed to the outer end ofthe adjusting rod. The connecting structure is stable in structure, high in universality, convenient to construct and high in safety.

Description

technical field [0001] The invention belongs to the technical field of curtain wall keels, and relates to a curtain wall beam-column connection structure, a construction tool 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 disas...

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
