Curtain wall keel quick connecting structure and construction method thereof

Abstract

The invention provides a curtain wall keel quick connecting structure and a construction method thereof, and belongs to the field of curtain wall keels. The problems that existing keels are low in connecting strength and poor in safety are solved. The curtain wall keel quick connecting structure comprises a connector fixed to the end of a cross beam and a connecting hole formed in the side wall ofa stand column, and further comprises a connecting rod; a baffle is fixed at the inner end of the connector; a stop block and a compression spring are arranged in the connector; a stop groove is formed in the outer wall of the stop block; a hinge part is arranged on the inner wall of the connector; the inner end of the connecting rod is hinged to the hinge part through a hinge shaft; the hinge shaft is sleeved with a torsion spring; the outer ends of the connecting rod are bent to form a connecting hook; a pressing groove is formed in the outer wall of the stop block; the depth of the pressing groove is gradually decreased from the outer end to the inner end; pressing holes are formed in the connector and the cross beam and are of strip-shaped hole structures; the end of the cross beam and the outer end of the stop block abut against the outer wall of the stand column; the outer end of the connecting rod penetrates through the connecting hole; and the connecting hook is hooked on theinner wall of the stand column. A keel can be connected quickly and locked safely, disassembly is not needed and construction is convenient.

Description

technical field [0001] The invention belongs to the technical field of curtain wall joists, and relates to a quick connection structure of curtain wall joists and a construction method thereof. Background technique [0002] The curtain wall is composed of keels and panels, and is mainly used as a building envelope for decoration. The application number is 201220312729.9, and it is a Chinese utility model patent named "a new connection structure for curtain wall keels". Hole, set the pin slot on the beam, and set the spring pin in the pin slot to cooperate with the positioning hole to realize the connection of the keel. Although it can facilitate the connection of the keel, it has the following problems: [0003] 1. The positioning hole is affected by the processing accuracy, and some spring pins may not be inserted into the positioning hole, and because the connection part is located between the beam and the column, it is impossible to observe whether the spring pin is inser...

AI Technical Summary

Problems solved by technology

[0003] 1. The positioning hole is affected by the processing accuracy, and some spring pins may not be inserted into the positioning hole, and because the connection part is located between the beam and the column, it is impossible to observe whether the spring pin is inserted in place;

[0004] 2. When installing, you can install the column first, and then install the beam between the two columns, but when disassembling, you can only remove the beam after dismantling the column, and the beam cannot be removed from any two columns, that is, it cannot be disassembled in disorder;

[0005] 3. Since the spring pin can expand and contract laterally along the beam, it cannot completely fix the beam and column like traditional fasteners, so the connection strength of the keel is low, which in turn affects the safety of the building
