Mortise lock type keel structure, construction tool and construction method

Abstract

The invention provides a mortise lock type keel structure, a construction tool and a construction method, and belongs to the field of curtain wall keels. The problems that an existing keel is limitedin disassembly and assembly and poor in stability are solved. The mortise lock type keel structure comprises cross beams and stand columns, fixing holes are formed in the side walls of the stand columns, fixing pieces are arranged at the ends of the cross beams and comprise inner fixing sleeves and outer fixing sleeves, the ends of the cross beams are fixed to the outer fixing sleeves, inner fixing plates and outer fixing plates are fixed to the inner ends of the inner fixing sleeves and the inner ends of the outer fixing sleeves, and first compression springs are arranged between the inner fixing plates and the outer fixing plates. Positioning magnetic blocks are fixed to one sides of the inner fixing plates, an inner inserting sleeve and an outer inserting sleeve are fixed to the inner wall of each inner fixing sleeve and the inner wall of each outer fixing sleeve, an inserting rod penetrates through each inner inserting sleeve and each outer inserting sleeve, a locking block is fixed to the outer end of each inserting rod, a stop sleeve is fixed to the rod wall of each inserting rod, a second compression spring sleeves each inserting rod, a limiting groove is formed at the innerwall of each inner inserting sleeve, and a limiting block is mounted on the wall of each inserting rod. Each fixing hole comprises an inserting hole and a lock hole. The keel structure can be inserted and locked at the same time, construction is convenient, and the structure is safe.

Description

technical field [0001] The invention belongs to the technical field of curtain wall keels, and relates to a plug-in lock type keel structure, a construction tool and a construction method. Background technique [0002] The keel of the curtain wall is fixed to the exterior wall and is used to install the panels of the curtain wall. Since the keel of the closed cavity structure has a great advantage in strength, a large number of beams and columns of the closed cavity structure are staggered to form the keel in the prior art; closed cavity The keel of the structure is connected through the elastic pins on the beams and the jacks on the columns, so it can only be installed in sequence, and the beams at any position cannot be removed at will, so there are limitations in the installation and removal methods. [0003] The application number is 201210276982.8, and the Chinese invention patent titled "a connection node between a curtain wall column and a beam" cleverly opens a round...

AI Technical Summary

Problems solved by technology

[0004] 1. It is necessary to open a round hole on the front side of the beam, which is cumbersome and destroys the integrity and stability of the beam;

[0005] 2. It is necessary to screw in the toothed pins one by one to penetrate the column for installation, and it is necessary to unscrew the toothed pins one by one to pass through the column for disassembly. The construction is troublesome

[0006] 3. The toothed pin can only penetrate the column horizontally, and cannot be completely fixed with the column, so the connection strength between the column and the beam is low
