Building formwork fastening suite

Abstract

The invention provides a building formwork fastening suite. The building formwork fastening suite comprises a threaded pull rod, a first locking part and a second locking part, wherein the first locking part and the second locking part are mounted at the two ends of the threaded pull rod; the first locking part is arranged at one hexagonal end of the threaded pull rod and comprises a first rotating sleeve, a long round fixing cylinder, a handle ring and a semicircular block; the semicircular block enables the handle ring to be fixed to the threaded pull rod, and the semicircular block is matched with a handle movable groove and a safety buckle of the long round fixing cylinder to control the movement and locking states of a handle; and the second locking part comprises a second rotating sleeve and a pull rod nut, and the second locking part is matched with the first locking part. The relative distance between building formworks is adjusted, the stability of the formworks is enhanced, and the problems of deformation, formwork explosion and the like of the building formworks during concrete pouring are prevented. Compared with the prior art, the building formwork fastening suite is more convenient and faster to use and operate, firmer in adjustment, long in service life and capable of being operated by only one person, all suites are connected and fixed, the overall strength is improved, and the requirements for stability and safety required by construction are met.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a construction formwork fastening set. Background technique [0002] The building template fastening kit is a highly integrated prefabricated building kit, which is suitable for the construction of fixing reinforced concrete frame structure and shear wall structure formwork. The single module is made in the factory, and the assembly connection between the kits is in It is an important component to ensure the construction stability of steel cofferdams and formwork in construction projects. In the construction of concrete structure formwork, it is often used to fix the two ends of the threaded tie rods with locks or gaskets and nuts. However, when fixing large-volume steel cofferdams or large formworks, the strength of such ordinary fastening kits It cannot meet the requirements, the tensile force it can withstand is limited, and it is easy to be damaged.

AI Technical Summary

Problems solved by technology

In the construction of concrete structure formwork, it is often used to fix the two ends of the threaded tie rods with locks or gaskets and nuts. However, when fixing large-volume steel cofferdams or large formworks, the strength of such ordinary fastening kits It cannot meet the requirements, the tensile force it can withstand is limited, and it is easy to be damaged. When the tensile force on the outside of the threaded tie rod exceeds the range of the limit nut, the nut is easy to jump off, so that the stability and safety of the steel cofferdam and large formwork cannot be obtained. Assure

In addition, the common integral threaded tie rods rely on nuts to adjust the width. When in use, at least two workers are required to assist in the operation on both sides of the formwork wall. The work efficiency is low, time-consuming and laborious, and it cannot meet the various sizes of formwork in construction
