Concrete construction formwork tensioning device

Abstract

The invention discloses a concrete construction template tensioning device which comprises an inserting rod capable of penetrating through a construction template, one end of the inserting rod is provided with a fastener used for limiting the construction template, the other end of the inserting rod is connected with a connecting piece, and the connecting piece is sleeved with a protection pipe. Compared with the prior art in which only one threaded rod is used, the template fixing device has the beneficial effects that the fastener for limiting the position of the template is arranged at the end part of the inserting rod, so that the template fixing device has a better positioning effect and a better tensioning effect on the template compared with the prior art in which only one threaded rod is used; and through the arrangement of the protection pipe, the threaded pipe and the steel wire can be conveniently withdrawn after the prefabricated part is manufactured.

Description

technical field [0001] The invention relates to the technical field of concrete construction formwork processing, in particular to a concrete construction formwork tensioning device. Background technique [0002] In the process of concrete construction, it is often necessary to prefabricate prefabricated parts of various specifications. In order to ensure the shape of the prefabricated parts, a tensioning device is required to limit the position of the construction formwork. The tensioning device of the concrete construction formwork in the prior art usually adopts threaded steel. However, in the actual operation process, due to the uncertainty of the installation position of the internal steel mesh, increasing the difficulty in the installation process, reducing the installation efficiency, increasing the time for pouring concrete, etc., a better concrete construction formwork is needed. Tighten the device. SUMMARY OF THE INVENTION [0003] The purpose of the present inv...

[0002] In the process of concrete construction, it is often necessary to prefabricate prefabricated parts of various specifications. In order to ensure the shape of the prefabricated parts, a tensioning device is required to limit the position of the construction formwork. The tensioning device of the concrete construction formwork in the prior art usually uses rebar , but in the actual operation process, due to the uncertainty of the installation position of the internal steel mesh, the difficulty of the installation process is increased, the installation efficiency is reduced, and the time for pouring concrete is increased, etc., so a concrete construction formwork with better effect is needed tensioning device
