A building formwork fastening kit

Abstract

A building formwork fastening kit, comprising a threaded tie rod and a first locking part and a second locking part installed at both ends of the threaded tie rod, wherein the first locking part is arranged at one end of the hexagonal shape of the threaded tie rod, including a first rotating sleeve cylinder, oblong fixed cylinder, handle ring and semicircular block, the semicircular block fixes the handle ring on the threaded rod, cooperates with the handle movable groove and safety buckle of the oblong fixed cylinder to control the activity and locking state of the handle, and the second locking part It includes a second rotating sleeve and a tie rod nut, and the second locking part cooperates with the first locking part to adjust the relative distance between the building formwork, enhance the stability of the formwork, and prevent the building formwork from being deformed when pouring concrete. Compared with the existing technology, the building formwork fastening set is more convenient to use and operate, and the adjustment is more reliable. The operation only needs a single person, and the service life is long. The connection between each set is fixed, which improves the overall strength. Meet the requirements of stability and safety required for construction.

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. When the tensile for...

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
