Regenerative block concrete connecting joint provided with H-shaped steel and U-shaped steel

Abstract

The invention discloses a regenerative block concrete connecting joint provided with H-shaped steel and U-shaped steel. The regenerative block concrete connecting joint includes a partial outsourcingH-shaped steel combined column provided with the H-shaped steel, a complete outsourcing U-shaped steel combined beam arranged horizontally in a crossed shape, two first rectangular steel plate connecting parts which are parallel to an H-shaped steel web plate, two second rectangular steel plate connecting parts which are perpendicular to the H-shaped steel web plate and a square outer ring plate with a threaded sleeve. According to the regenerative block concrete connecting joint, on the one hand, because no dense piercing parts are arranged in a joint core area, the problem of put construction of waste concrete blocks is solved, and in addition, the complete outsourcing U-shaped steel combined beam is used, so that the utilization ratio of waste concrete of a structural system can be significantly improved; and on the other hand, outsourcing profiled steel is used in a bean-column structure, so that the processes of steel bar binding and formwork erecting and dismantling can be reduced, meanwhile, a web plate of the U-shaped steel can directly penetrate through the partial outsourcing H-shaped steel combined column, beam shear force and bending moment are transferred better, and continuity of force transferring and safety of the joint are ensured.

Description

technical field [0001] The invention relates to the technical field of waste concrete recycling, in particular to a regenerated block concrete connection node with partially outsourced H-shaped steel composite columns and fully outsourced U-shaped steel composite beams. Background technique [0002] Concrete is currently the most widely used building material, widely used in the construction of industrial and civil buildings, municipal public works, highways and railways, ports and waterways, water conservancy and hydropower and other industries. With the rapid development of the construction industry, a large number of demolition and restoration of old buildings have produced a large amount of construction waste, of which concrete occupies a large proportion. This situation undoubtedly makes the recycling of waste concrete one of the urgent issues to be solved to realize the sustainable development of the construction industry, develop the circular economy, and establish an...

AI Technical Summary

Problems solved by technology

Due to the serious lack of design of the partially outsourced H-shaped steel composite column-fully outsourced U-shaped steel composite beam joints in China, it is rare to see the application examples and related researches of the partially outsourced H-shaped steel composite column-fully outsourced U-shaped steel composite beam structure system material
