Fully-assembled square steel tube beam-column connecting joint and construction method

Abstract

The invention discloses a fully-assembled square steel tube beam-column connecting joint and a construction method thereof. The fully-assembled square steel tube beam-column connecting joint comprisesan upper joint plate, a lower joint plate is fixedly connected to the lower end of the upper joint plate through bolts, a plurality of bolt holes are formed in the upper joint plate and the lower joint plate, and square holes are formed in the middle of the upper joint plate and the middle of the lower joint plate; sleeves are fixedly arranged on the upper joint plate and the lower joint plate; square steel pipe columns are arranged in the sleeves of the upper joint plate and the lower joint plate respectively in a sleeved manner and fixedly connected with the sleeves; a square steel cross beam and a square steel longitudinal beam are also included, and L-shaped steel connecting pieces are fixedly connected to the two sides and the upper surface of the square steel cross beam and the square steel longitudinal beam; one ends of the L-shaped steel connecting pieces at the two sides of the square steel cross beam and the square steel longitudinal beam are fixedly connected with the upperjoint plate, and the other ends of the L-shaped steel connecting pieces are fixedly connected with the square steel cross beam or the square steel longitudinal beam; and one ends of the L-shaped steel connecting pieces on the upper surfaces of the square steel cross beam and the square steel longitudinal beam are fixedly connected with the square steel pipe columns, and the other ends of the L-shaped steel connecting pieces are fixedly connected with the square steel cross beam or the square steel longitudinal beam. The fully-assembled square steel tube beam-column connecting joint is simplein construction, the workload of welding and assembling can be reduced, and the construction cost can also be saved.

Description

technical field [0001] The invention belongs to the technical field of building structures, and more specifically, the invention relates to a fully assembled square steel pipe beam-column connection node and a construction method. Background technique [0002] The prefabricated steel structure has the characteristics of material saving, energy saving and environmental protection, light weight, high strength, good flexibility, high degree of industrialization and industrialization, etc. In the 1980s, my country began to explore the research and exploration of prefabricated steel structure houses, but it stagnated in the later period due to the adjustment of the building structure industry. By 2016, my country's prefabricated steel structure is mainly concentrated in the public building system, and the prefabricated steel structure residential system accounts for only about 4% of the entire steel structure building. In order to promote supply-side structural reform and new ur...

Problems solved by technology

[0004] At present, the connection of beam-column joints in steel structures is mostly welded and bolted. Fully welded joints can effectively reduce the steel consumption and improve the strength and stability of the steel structure. However, the quality of welding is easily affected by the welding process. Welding personnel have high requirements, and there are certain problems in quality assurance. At the same time, when subjected to external forces, its plastic deformation tends to concentrate in the node domain, which cannot meet the building's seismic requirements of "strong nodes, weak components". According to the design specifications, only simple installation on site can meet the engineering requirements, and the quality is also guaranteed. The bolt connection involves the design of connecting plates, sleeves, etc. At this stage, the bolt connection between square steel pipe columns and H-shaped steel beams is relatively difficult. Many, the present invention develops a construction technology suitable for fully assembled square steel pipe beam-column connection nodes by optimizing the traditional design
