Device for fixing straining pieces between urban utility tunnel construction formworks

Abstract

The invention discloses a device for fixing straining pieces between urban utility tunnel construction formworks. The device comprises two plates, first communication holes run through the side wallsof the two plates respectively, first installation grooves are formed in the side walls at the opposite ends of the two plates respectively, the first installation grooves are formed in the outer sides of the first communication holes, and two second installation grooves are symmetrically formed in the inner side walls of the two first installation grooves respectively. Clamping grooves are formedin the opposite inner side walls of the second installation grooves respectively, first installation blocks are placed in the two first installation grooves, two second installation blocks are fixedly connected to the side walls of the first installation blocks, and the two second installation blocks extend into the second installation grooves opposite to the second installation blocks and abut against the inner side walls of the second installation grooves respectively. The structural design is reasonable, it is convenient for constructors to fix the straining pieces, it is also convenient for the constructors to disassemble the straining pieces, and therefore, the construction efficiency of the constructors can be improved.

Description

technical field [0001] The invention relates to the technical field of urban construction, in particular to a tie rod fixing device between construction templates of an urban comprehensive utility gallery. Background technique [0002] In recent years, the development of my country's infrastructure construction has been very rapid. However, due to the low starting point of my country's infrastructure construction, the construction of urban comprehensive pipe corridors is still in its infancy, and the construction methods are relatively traditional, that is, scaffolding or wood plywood is still used And so on, the formwork error is large, which will affect the quality of construction. [0003] During the construction process, it is necessary to set a tie rod between two adjacent construction formworks. Under the action of the tie rods, it can ensure that the distance and position between the two adjacent construction formworks will not change, thereby ensuring that the constru...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problems of cumbersome installation and inconvenient disassembly of the existing tie rods, and proposes a tie rod fixing device between the construction templates of urban comprehensive pipe gallery, which can not only facilitate construction personnel to install the fixed tie rods, but also facilitate Construction personnel carry out disassembly work, which can improve the construction efficiency of construction personnel
