Vertical joint connection joint of steel tube concrete prefabricated shear wallboards and assembling method thereof

Abstract

The invention relates to a vertical joint connection joint of a steel tube concrete prefabricated shear wallboards and an assembling method thereof, and belongs to the technical field of prefabricatedconcrete member structures. A connecting end of each prefabricated wallboard is provided with connecting grooves, protrusions and pre-embedded anchor ribs, one ends of the pre-embedded anchor ribs wrap reinforcing steel bars in the prefabricated wallboards, the other ends of the pre-embedded anchor ribs warp joint bars and a square steel tube, the protrusions and grooves of the prefabricated wallboards are combined and assembled to form a mortar injecting passage, and a grouting material is injected into one square steel tube hole and four joint bar holes. The vertical joint connection jointof the steel tube concrete prefabricated shear wallboards and the assembling method thereof can bear the vertical load, reduce the probability of overall instability caused by accidental load, avoid acontinuous collapse phenomenon of the structure, cast concrete in an important position part of a joint area, and achieve the equivalent cast-in-situ of a connection joint area of a prefabricated component, has good structural integrity and seismic performance, and has outstanding physical characteristics and significant progress compared to the prior art.

Description

technical field [0001] The invention belongs to the technical field of prefabricated assembled concrete member structures, and in particular relates to a vertical joint connection node of a steel pipe concrete prefabricated shear wall panel and an assembly method. Background technique [0002] At present, my country's traditional construction production methods mostly adopt on-site pouring. This method generally has high construction labor costs, large on-site operations, low production efficiency, and is greatly affected by the natural environment. Project quality and safety are worrying, serious environmental pollution, resources and Serious energy waste and other issues. Recently, with the gradual implementation of my country's construction industrialization policy, the construction industry has ushered in a new period of change, and the assembly rate of various components has gradually increased. As the main force-bearing wall, the wall has strict requirements on the perf...

Problems solved by technology

In the traditional prefabricated shear wall structure, the vertical joint connection is mainly through the reserved steel bar of the prefabricated shear wall, which is connected with the longitudinally stressed steel bar at the vertical joint position, and then the formwork is erected and the concrete is poured afterwards. This vertical joint connection technology exists The following problems are: difficult to connect steel bars, need to set up formwork and pour concrete, the process is complicated, the construction is difficult, the construction period is long, and the quality is difficult to guarantee. This requires the development of a fast connection, convenient construction, good construction quality, good earthquake resistance and ductility. Prefabricated prefabricated shear wall structure vertical seam connection nodes with superior mechanical properties simplify the connection structure of nodes during on-site construction on the premise of meeting the bearing capacity performance, facilitate on-site operation, simplify construction technology, and reduce assembly time
