Connecting device for connecting modular steel frames and connecting method of connecting device

Abstract

The invention relates to a connecting device for connecting modular steel frames. The connecting device at least comprises first square steel tube columns and second square steel tube columns. The ends of the first square steel tube columns and the ends of the second square steel tube columns are hollow. The first square steel tube columns and the second square steel tube columns are connected through inner sleeves, the inner sleeves are in clearance fit with the first square steel tube columns and the second square steel tube columns, positioning blocks and bearing steel angles are arranged on the peripheral rings of the inner sleeves, the positioning blocks are located below the bearing steel angles, the lower edges of the positioning blocks are parallel to column openings of the first square steel tube columns, and the bearing surfaces of the bearing steel angles are parallel to column openings of the second square steel tube columns. The modular steel frames are partially machined in a factory in advance and then constructed on a construction site, the procedures of site construction are greatly reduced, the construction time is shortened, and the environment on site is not excessively influenced; the modular steel frames are welded to the inner sleeves, the firmness degree between the frames is greatly enhanced, and the risk caused by screw or bolt looseness is avoided.

Description

technical field [0001] The invention relates to the technical field of construction engineering equipment, and relates to a connection node structure between steel structure modules in a steel structure modular building, in particular to a connection device and a connection method for connecting modular steel frames. Background technique [0002] At present, my country's construction industry is in a period of rapid development, and the annual increase in housing construction has become the world's first. At the same time, it also increases the energy consumption of buildings in our country, which accounts for about 33% of the total energy consumption of the society. The problems of building energy consumption and environmental pollution have also attracted more and more attention. At present, domestic buildings are still constructed by traditional extensive and labor-intensive manual production methods, which have the characteristics of long construction period, high energy...

Problems solved by technology

However, the workload of this construction method is huge, and each screw hole needs to be fixedly connected, and the increase of the connection position will undoubtedly increase the risk of loosening and reduce the bearing capacity of the building
