Hollow plastic formwork

Abstract

The invention discloses a hollow plastic formwork. The hollow plastic formwork is formed by tightly splicing a plurality of formwork bodies in the longitudinal direction and the transverse direction respectively, and the outline of the formwork body is shaped like a cuboid; and the adjacent formwork bodies in the longitudinal direction are connected through a plurality of longitudinal splicing positioning pieces, and the adjacent formwork bodies in the transverse direction are connected through a plurality of transverse splicing positioning pieces. According to the hollow plastic formwork, thelongitudinal splicing positioning pieces and the transverse splicing positioning pieces are used for positioning connecting in the splicing process, so that subsequent matching construction of connecting pieces and supporting structures is convenient to achieved, the number of operators can be decreased, and the construction and disassemble working efficiency of building formwork structure can beimproved. Meanwhile, the structural strength and loading capacity of the formwork can be further improved, and formwork deformation is reduced. The reduction of the using number of the connecting pieces also reduces the operations such as drilling and grooving on the formwork, and the service life of the formwork is further prolonged.

Description

technical field [0001] The invention belongs to the technical field of plastic templates, in particular to a hollow plastic template. Background technique [0002] The formwork in the construction industry is a temporary support structure, which enables the concrete structure and components to be formed according to the specified position and geometric size, maintains its correct position, and bears the self-weight of the building formwork and the external load acting on it. The building formwork structure used in the construction of cast-in-place concrete structures is mainly composed of three parts: panels (formwork), support structures and connectors. The formwork is a load-bearing slab that directly contacts the newly poured concrete; the support structure is a temporary structure that supports the formwork, concrete and construction loads, ensuring that the building formwork structure is firmly combined without deformation or damage; the connector is to connect the form...

AI Technical Summary

Problems solved by technology

However, although the large-area single-block formwork is not heavy, it is too large. During the construction process, multiple people are required to coordinate positioning at different positions, and special personnel are required to use screws and other connectors to connect, which is inconvenient to operate.
