Injection section combination building template

Abstract

The invention relates to an injection section combination building template, which comprises at least more than two building templates made of a plastic material and is characterized in that a frame is arranged at four sides of each building template; connection holes are formed in the frame; various connection holes are connected through connection pins; a fastening locking head is arranged on the head part of each connection pin; the building template in the proposal is made of the plastic material and has the advantages of light weight, no corrosion, long service life and low cost; the building template is not stuck with concrete and can be recycled for many times; when being used, various building templates are flatly arranged; the connection holes on various building templates correspond with each other; the connection pins are inserted into the connection holes; the connection pins rotary so that the fastening locking heads on the head parts of the connection pins are clamped on the inner frame of the frame to fix; and various building templates are connected with each other together. According to the proposal provided by the invention, various building templates are mutually combined together in a matched manner through pin holes; and the building templates are simple in structure, convenient to install and easy to disassemble.

Description

technical field [0001] The invention relates to an injection-moulded building template, which is mainly used for pouring concrete in construction projects. Background technique [0002] In building construction, when concrete components such as beams, columns, and shear walls are poured on site, a large number of building formwork must be used. At present, the commonly used building formwork mainly includes steel formwork and wooden formwork. Wooden formwork is light in weight, but it is easy to rot due to water erosion during use, and it will be damaged after two to three times of use, so the number of repeated uses is low, and the use efficiency is low. , which brings inconvenience to the construction; in addition, a large amount of wood must be used for the wooden formwork, which consumes a large amount of forest resources. Steel formwork has a strong structure and can be reused more times than wooden formwork, but it is heavy, inconvenient to operate, easy to rust, hig...

AI Technical Summary

Problems solved by technology

Wooden formwork is light in weight, but it is easy to rot due to water erosion during use, and it will be damaged after two to three times of use, so the number of repeated uses is low, and the use efficiency is low. , which brings inconvenience to the construction; in addition, the wooden formwork must use a large amount of wood, which consumes a large amount of forest resources

Steel formwork has a strong structure and can be reused more times than wooden formwork, but it is heavy, inconvenient to operate, easy to rust, high in price, and increases construction costs, and also has the defect of being easy to bond with concrete when used. Difficult to demould and thus less convenient for construction

In particular, the above two formworks are very inconvenient to assemble. The wooden formwork usually needs to be fastened with nails, which is troublesome to assemble and disassemble; the steel formwork is usually fastened with bolts and nuts, which is also troublesome to assemble and disassemble.
