Built-in self-locking butt connector and its construction method

Abstract

The invention discloses a built-in self-locking butt connector, which comprises a lower connection square cylinder, an upper connection square cylinder, two symmetrically arranged connection plates and a spring clamped between the two connection plates, the lower connection square cylinder The left and right ends of the inner wall of the front side wall and the rear side wall are respectively provided with a plurality of positioning ribs arranged at intervals up and down, and positioning grooves are respectively provided on both sides of the bottom of the connecting plate, and the bottom of the connecting plate can be Insert into the lower connecting square cylinder and make the positioning groove match and engage with the positioning rib, the outer surface of the top of the connecting plate is provided with a plurality of normal longitudinal teeth, and the bottom end of the upper connecting square cylinder is provided with positioning port. The upper connecting cylinder and the lower connecting square cylinder of the present invention are respectively fixed on the inner wall of the steel pipe or the section of the column end. After the steel pipes are butted, there is no excess part protruding from the outer circumference of the steel pipes, which is especially suitable for the compact and precise on-site installation requirements of the integrated modular building.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a built-in self-locking butt connector and a construction method thereof. Background technique [0002] Integrated modular building is a new type of construction mode. The building modules with a high degree of completion complete more than 90% of the construction in the factory environment, and then transported to the construction site with large-scale transportation equipment for assembly. The assembly process is mainly through the on-site structural connection of the key module nodes to form the overall rigidity of the structure, followed by matching the joints between the building modules to ensure its safety, waterproof, sound insulation and anti-corrosion and other architectural requirements. Because of the limitations of transportation, lifting and installation, integrated modules are often produced, transported and installed in the form of cuboid modules. The longe...

Problems solved by technology

Although this form solves the problem of the small construction plane of the modular building site and improves the work efficiency of the site, it has poor seismic and wind resistance performance and is not suitable for medium and high-rise modular buildings.
