Problems solved by technology
[0003] In the prior art, under the constraints of design requirements, construction environment, and support materials, the support rods are easy to bend after being stressed, and the verticality and flatness of the formwork must be controlled by the pull rods
The existing support rods can only be supported but not pulled, resulting in low accuracy of formwork fixing, and the use of other auxiliary tools will cause waste of construction materials

The invention discloses a symmetric support and symmetric pull rod device for fixing a template. The device adopts a symmetric structure, and comprises a symmetric support inner rod, a symmetric pull outer rod, a connecting block and a sleeve, wherein an internal thread is formed in the symmetric inner rod; an external thread is formed in the symmetric pull outer rod; the symmetric pull outer rod penetrates a through hole in the template and is screwed with the symmetric inner rod; the connecting block is fixedly connected with the symmetric pull outer rod; the outer diameter of the connecting block is larger than the inner diameter of the through hole; the sleeve is arranged on the symmetric support inner rod in a sleeving manner; the outer diameter of the sleeve is larger than the inner diameter of the through hole. According to the symmetric support and symmetric pull rod device provided by the invention, the symmetric inner rod has support function on the template, and the symmetric pull outer rod has pulling function on the template, so that the support and pulling of the template is realized, the verticality and the flatness of the template are guaranteed, the fixing accuracy of the template is improved, circulated use is facilitated, construction processes are reduced, working efficiency is increased, adjusting is flexible and convenient, the structure is simple, and the raw material is saved.
Description
technical field [0001] The invention relates to a pair of brace and tie rod device for fixing a formwork. Background technique [0002] Formwork fixing is a key process in concrete pouring construction. The accuracy of formwork fixing directly affects the personal safety of construction workers during concrete pouring and the quality of concrete after pouring. [0003] In the prior art, under the constraints of design requirements, construction environment, and support materials, the support rods are easy to bend after being stressed, and the verticality and flatness of the formwork must be controlled by tie rods. Existing support rods can only support but not pull, resulting in low formwork fixing accuracy, and the use of other auxiliary tools will cause waste of construction materials. Contents of the invention [0004] In order to support and pull the formwork at the same time, improve the accuracy of formwork fixing and save costs, the present invention provides a pai...
