External pre-stressed tendon reinforcing steering block for building structure

Abstract

The invention discloses an external pre-stressed tendon reinforcing steering block for a building structure. The external pre-stressed tendon reinforcing steering block comprises a U-shaped steel plate, an external tendon tension L-shaped steel plate and steering solid round steel, wherein the U-shaped steel plate consists of two side plates and a bottom plate; the external tendon tension L-shaped steel plate is formed by welding a horizontal top plate and a vertical plate; the horizontal top plate is welded together with the bottom plate of the U-shaped steel plate; an oval preformed hole is formed in the vertical plate; an external pre-stressed steel strand positioning steel plate is additionally welded beside a hole; the steel plate is also an L-shaped steel plate reinforcing rib; the steering solid round steel is a steering device for an external pre-stressed steel strand; limiting baffle plates are welded at the two ends of the steering solid round steel; an arc-shaped steering base plate is arranged at a steering point under the steering solid round steel; and the steering block is a tension anchoring end as well as a steering block. The external pre-stressed tendon reinforcing steering block has the advantages of simple structure, convenience in constructing and easiness in detaching; the tension end of the pre-stressed tension is combined with the steering block, so that space is saved; and the external pre-stressed tendon reinforcing steering block is particularly suitable for external prestress reinforcing engineering of a building structure beam body with four and less external pre-stressed reinforcing steel strands.

Description

technical field [0001] The invention relates to a civil engineering structural component, in particular to a building structure external prestressed tendon reinforced steering block, which is suitable for reinforcing and reforming existing building structural beams in construction engineering. Background technique [0002] Since the reform and opening up, my country's civil engineering construction has been changing with each passing day, and newly-built high-rise buildings, exhibition centers, railways, highways and bridges, ports, waterways and large-scale water conservancy projects have sprung up like mushrooms after rain. However, today when building energy conservation is vigorously advocated, we should also pay attention to the reinforcement and transformation of existing buildings while carrying out new civil engineering infrastructure construction. Existing buildings often have insufficient bearing capacity, cracks, and poor seismic performance of concrete structures...

AI Technical Summary

Problems solved by technology

[0004] Most of the existing steering blocks are designed for high-strength concrete bridge structures, but less involved in the reinforcement and transformation of existing houses in the field of construction engineering, and most of the steering blocks and tension anchorage ends are set separately, and the tension anchorage ends are generally set At the node where the beams and columns intersect, it needs to occupy a relatively large building space
