Truss rebar protecting jacket for PC component

Abstract

The invention discloses a truss rebar protecting jacket for a PC component. The truss rebar protecting jacket for the PC component comprises two clamping plates. A handheld end and a clamping end are arranged at the two ends of each clamping plate, a hinge joint portion is further arranged between the handheld end and the clamping end of each clamping plate, the hinge joint portions of the two clamping plates are connected with each other, and an elastic device which is used for driving the two clamping ends to be extruded with each other is further arranged between the two clamping plates. A clamping assembly is further arranged at each clamping end and comprises a rubber layer and a brush. The rubber layers and the brushes are connected to the end portions of the clamping ends and detachably connected to the inner surfaces and the outer surfaces of the clamping ends correspondingly, and the length of each brush is larger than the width of the corresponding rubber layer. The truss rebar protecting jacket for the PC component can fulfill a certain protection function on an upper main rebar, and a reasonable solution is provided for protection of the upper main rebar in truss rebars in the prior art. When string rebars are clamped, upward slide can be avoided, and the rebars can also be prevented from being inclined towards the horizontal plane in the clamping process.

Description

technical field [0001] The invention relates to a truss bar sheath for PC components, which belongs to the technical field of PC component protection. Background technique [0002] The prefabricated truss bar is composed of three straightened steel bars arranged in a triangle, and connected by resistance spot welding of two long wavy bent web steel bars. The steel bars have various types and stable spacing, and are suitable for sandwich concrete connecting concrete slabs and secondary pouring Between the connecting bars, the laminated floor slabs with steel trusses can withstand greater shear stress. [0003] During the manufacturing process of PC components (prefabricated concrete), prefabricated truss bars need to be used. In the prefabrication process of some products, only two of the three straightened steel bars need to be embedded in the structure. The top straightened bar is used for secondary pouring. This determines that the truss bars cannot be stained with concr...

AI Technical Summary

Problems solved by technology

This determines that the truss bars cannot be stained with concrete during the first pouring process, otherwise it will affect the quality of the second pouring, because the steel bars glued to the concrete will not be able to directly contact the concrete fully during the second pouring process , so that the bonding force between steel and concrete decreases

[0004] At present, there is a lack of special protective gear for the uppermost straightened steel bar in the existing technology. In the process of on-site construction, it is often wrapped with plastic film, newspaper, etc. to achieve the purpose of isolating the concrete, and the actual use effect is not good.
