Description

Construction method and device for interior wall template

The invention relates to a construction method and device for interior wall formwork, and belongs to the construction method and installation of interior wall formwork.

During building construction, the two sets of internal and external formwork are often installed to maintain a certain distance for the grouting construction wall. When the grouting construction is completed, the concrete needs to be demoulded after the solidification, because the outer formwork is not subject to space. It can be easily dismantled due to space constraints. Due to space constraints, it is often necessary to pry or tap the formwork to demould it. Therefore, it is easy to generate side pressure on the fully solidified concrete and cause it to collapse, so it cannot be self-supporting when the concrete is solidified. Early demolding occurs at the time of strength. It usually takes 24 hours, or even more time to wait for the concrete to solidify. It takes more time and the speed of construction is limited. Therefore, the industry has been looking for methods of disassembly, such as Chinese patent applications. No. 95101674.1 (announcement number CN1127830A) discloses a method and a device for demoulding a building formwork, which has the disadvantages of complicated structure and inconvenient operation. In addition, Chinese Patent Application No. 98223894.0 (publication number CN2359390Y) discloses an internal wall formwork climbing device, which can avoid the friction between the formwork and the wall and reduce the occupation of the site, but it has the disadvantages After the internal wall formwork is climbed, the construction of the lower floor is required immediately, and the internal wall formwork must be supported after the floor has solidified. The construction speed is slow and the construction period is long. In addition, during the construction of the lower floor, the internal wall The formwork must be hung all the time, or it needs to be lifted away from other places. The lifting task is heavy and the operation is not convenient.
