H-shaped steel structure mortise and tenon self-locking connecting system and construction method thereof

Abstract

The invention relates to the technical field of building construction, and discloses an H-shaped steel structure mortise and tenon self-locking connecting system and a construction method thereof. The H-shaped steel structure mortise and tenon self-locking connecting system comprises a steel column, a cross beam connected to the steel column and a mortise and tenon component used for connecting the steel column and the cross beam; the tenon-and-mortise component comprises tenons and mortises which are connected in a clamped mode, the tenons are arranged at the two ends of the cross beam in the length direction and comprise webs with the end faces being inclined slopes, flange plates arranged on the upper sides and the lower sides of the webs and tenon plates arranged on the side faces of the webs, the outer side faces of the tenon plates are inclined slopes parallel to the end faces of the webs, and the bottom faces of the tenon plates are of Z-shaped broken line structures; an the mortise comprises two C-shaped steel structures which are symmetrically arranged in a back-to-back mode, a gap is reserved between the two C-shaped steel structures, inclined tenon grooves are formed in the gap and the inner sides of the C-shaped steel structures, the inner side faces of the inclined tenon grooves are inclined planes, the top faces of the inclined tenon grooves are of Z-shaped broken line structures, a plugging plate used for preventing the web from moving towards the inner side is arranged in the gap, and the plugging plate abuts against the outer side faces of the tenon plates and/or the end faces of the webs.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to an H-shaped steel structure mortise and tenon self-locking connection system and a construction method thereof. Background technique [0002] At present, prefabricated buildings have the advantages of environmental protection and fast construction speed, and become one of the important directions of future construction development. At present, the country is vigorously promoting prefabricated buildings and developing construction industrialization to improve the environment and control energy consumption. The prefabricated steel structure is one of the important components of the prefabricated building. In the past, in the prefabricated steel structure, the beam-column joints were mainly connected by welding, and the force between the beams and columns was transmitted by the weld. This kind of joint requires high welding quality, complex construction, large welding ...
