In the process of pouring concrete walls and columns, the wall and column templates are deformed by larger lateral pressure of concrete, and a back ridge and opposite pulling reinforcing system is adopted to ensure the safety of the bearing capacity of the templates and the forming quality of the concrete.
Along with the continuous development of the building industry, the concrete forms also undergo the transition of wood forms, steel forms, plastic forms, aluminum alloy forms and the like, but the back edge of the corresponding forms has little change. The biggest problems among them are: the prior back edges for reinforcing walls and column templates are welded by section steel according to the shape and the size of the components, if the back edges are lengthened or cut according to the length change, the construction period of the template engineering can be seriously influenced, and the method leads each project and each component to be provided with corresponding back edges, so that the back edges are difficult to be commonly used. Even if the combined back edge is anchored by adopting the interpenetrating screw rod with the holes at the end part of the back edge, the fine adjustment can be realized, the problem that the specifications of different types of templates are not uniform is difficult to consider, and the problem of universality is not solved. Secondly, because the steel back is not too long due to the weight, the middle is lengthened by adopting a mode of adding a connecting piece and a screw rod, the connecting node is not only troublesome to install, but also is easy to loosen, and the construction progress and quality are often influenced. In addition, the steel back edge is easy to rust, the recovery value is low, the transportation and the cleaning are troublesome, and therefore the back edge is basically used up for one project and is scrapped, and the waste is serious.
