A curtain wall closed cavity keel system and its construction method

Abstract

The invention provides a curtain wall closed-cavity keel system and a construction method thereof, belonging to the field of curtain wall connection structures. It solves the troublesome disassembly and assembly of the keel of the existing curtain wall and the problems of unstable structure. The curtain wall closed-cavity keel system includes a closed-cavity column and a beam. The end of the beam is embedded with a connector, and a pin is fixed on the connector. The side wall of the column is provided with a pin hole. An adjustment seat is fixed, and an outer adjustment hole and an inner adjustment hole are provided on the connector and the adjustment seat. The rod wall near the outer end is provided with external threads, the adjustment seat is fitted with an adjustment sleeve, the end of the adjustment sleeve is fixed with an adjustment plate, the adjustment plate is fixed with a locking nail, the outer end of the locking nail is fixed with a lock head, and the side wall of the column is set. There is a lock hole, a tension spring 1 is arranged between the connecting head and the beam, and a tension spring 2 is arranged between the adjustment seat and the adjustment sleeve. The keel system is easy to assemble and disassemble, and the structure is stable.

Description

technical field [0001] The invention belongs to the technical field of curtain wall connection structures, and relates to a curtain wall closed-cavity keel system and a construction method thereof. Background technique [0002] The curtain wall includes keels and wall panels installed on the keels. The keels include interconnected beams and columns. The beams and columns can be divided into open-cavity profiles and closed-cavity profiles structurally. The beams of open-cavity profiles need to be matched with fasteners through corner codes. It is fixed on the column, so the operation is troublesome, and more keels use closed-cavity profiles; for example, the application number is 201720782762.0, and the Chinese utility model patent titled "A Reinforced Horizontal and Vertical Keel Connection Structure" discloses a common closed-cavity profile The profile keel structure connects the beam and the column by fixing the sleeve core at the end of the beam and fixing the spring pin ...

Problems solved by technology

[0002] The curtain wall includes keels and wall panels installed on the keels. The keels include interconnected beams and columns. The beams and columns can be divided into open-cavity profiles and closed-cavity profiles structurally. The beams of open-cavity profiles need to be matched with fasteners through corner codes. It is fixed on the column, so the operation is troublesome, and more keels use closed-cavity profiles; for example, the application number is 201720782762.0, and the Chinese utility model patent titled "A Reinforced Horizontal and Vertical Keel Connection Structure" discloses a common closed-cavity profile The profile keel structure connects the beam and the column by fixing the sleeve core at the end of the beam and fixing the spring pin on the sleeve core so that the spring pin fits with the pin hole on the side of the column to connect the beam and the column, but it has the following problems:

[0003] 1. Affected by the processing accuracy, some spring pins may not be inserted into the pin holes, and it is impossible to tell whether all the spring pins are inserted in place outside the keel, which has potential safety hazards, poor stability, and cannot be disassembled;

[0004] 2. The beam cannot be stably fixed to the column with the spring pin. Usually, an additional connection mechanism is required to further strengthen the beam and the column. The construction is very troublesome, and it is necessary to improve it
