UHPC (Ultra High Performance Concrete)-necking type profiled steel sheet composite template composite shear wall

Abstract

The invention discloses a UHPC (Ultra High Performance Concrete)-necking type profiled steel sheet composite template combined shear wall. The shear wall comprises two necking type profiled steel sheets, the two necking type profiled steel sheets are oppositely distributed, UHPC layers are formed on the outer sides of the two necking type profiled steel sheets in a pouring mode, J-shaped hooks are arranged on the two necking type profiled steel sheets, one ends of the J-shaped hooks are located in the UHPC layers, longitudinal shear keys and transverse shear keys are fixed to the ends of the J-shaped hooks, the other ends of the J-shaped hooks penetrate through the necking type profiled steel sheets, and the longitudinal shear keys and the transverse shear keys are fixed to the UHPC layers. J-shaped hooks are arranged on the two necking-down type profiled steel sheets, the J-shaped hooks on the two necking-down type profiled steel sheets are in one-to-one correspondence, the J-shaped hooks on one necking-down type profiled steel sheet are connected with the corresponding J-shaped hooks on the other necking-down type profiled steel sheet in an opposite pulling mode, and concrete is poured between the two necking-down type profiled steel sheets. And under the action of a horizontal load, the shear failure is not easy to occur.

Description

technical field [0001] The invention belongs to the technical field of steel structures, and relates to a UHPC-neck type profiled steel composite formwork combined shear wall. Background technique [0002] In the existing double-steel plate concrete composite shear wall structure, the exposed steel plate makes the fire performance of the structure poor, and the structure is prone to bulging under horizontal loads. At the same time, the traditional steel plate-concrete composite shear wall is only connected by the through connector without setting the shear key, which results in insufficient load transfer between the steel plate and the concrete, and makes the structure prone to shear failure under the action of horizontal load. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned shortcoming of prior art, provide a kind of UHPC-neck-type profiled steel plate composite formwork combination shear wall, the fireproof perfo...

[0002] In the existing double steel plate concrete composite shear wall structure, the exposed steel plate makes the fire performance of the structure poor, and the structure is prone to bulge phenomenon under the action of horizontal load

At the same time, the traditional steel plate-concrete composite shear wall only uses the connecting piece to connect without setting the shear key, resulting in insufficient load transfer between the steel plate and the concrete, making the structure prone to shear failure under the action of horizontal load
