Self-supporting structure of a self-supporting building formwork

Abstract

The invention discloses a self-supporting structure of an expandable building formwork, comprising a main board, a first motor, an electric telescopic rod and a second motor, the lower end of the main board is fixedly connected with a slider, and the left and right ends of the two-way threaded There is a support plate connected through it, and the monomers of the runners are connected by the first belt transmission. The middle part of the main board is provided with a chute, and the lower ends of the front and rear ends of the support plate are provided with adjustment grooves. The installation The lower end of the buckle is cross-connected with a folding left rod and a folding right rod through a hinge, an electric telescopic rod is installed and connected between the support plate and the bottom plate, and the lower end of the bottom plate is connected with a fixing device, and the main board is connected with a sub-board . The self-supporting structure of the unfolded building formwork has the function of automatically adjusting the height, and it is convenient to adjust the supporting area according to the needs. At the same time, it is also easy to be firmly installed on the ground, easy to disassemble, easy to fold and store, and avoids occupying space.

Description

technical field [0001] The invention relates to the technical field of building formwork, in particular to a self-supporting structure of an unfolded building formwork. Background technique [0002] The building formwork is mainly used in the construction of buildings. It is a temporary support device. The general building formwork is fixed by the supporting structure. According to the size and shape of the required building, the building formwork is enclosed and assembled, and finally the concrete is poured into it. To the inside of the formwork, so as to complete the manufacture of cast-in-situ slabs or prefabricated slabs, and the purpose of formwork support at the same time is to ensure the quality and safety of concrete projects, speed up the progress of the project, and reduce project costs. [0003] At present, the commonly used building templates still have large and small problems, which are not convenient for normal use during construction, such as the following de...
