Abstract

The invention discloses a lightweight formwork for a building. The lightweight formwork comprises a middle layer, a lower layer and an upper layer. A plastic layer serves as the lower layer, a plastic layer serves as the upper layer, and a composite layer serves as the middle layer. The middle layer and the upper layer are glued and pressed together. The middle layer and the lower layer are glued and pressed together. A stepped groove is formed in one end of the upper layer. A protrusion table matched with the stepped groove is arranged on the other end of the upper layer. The lightweight formwork is composed of the plastic layers and the composite layer, so that the overall weight is low; through the design of the stepped groove and the matched protrusion table, the building formwork can be used in a spliced mode, the assembling efficiency is improved, gaps between formworks are not prone to occur, the defect that sewage such as mud is prone to being injected when the formwork is used is overcome, the overall intensity of the formwork is increased, and the service life of the formwork is prolonged.

Description

technical field [0001] The invention relates to the field of building templates, in particular to a lightweight building template. Background technique [0002] Building formwork is the formwork and bracket formed by pouring concrete. It is a temporary structure and an important construction tool in the construction of building structures. Building formwork is an important tool for concrete structure engineering construction. In cast-in-place concrete structure engineering, formwork technology directly affects the quality, cost and benefit of engineering construction, so it is an important content to promote the progress of my country's construction technology. [0003] There are metal and wooden building templates on the market. Wooden building formwork is easy to be damaged during the construction process. Due to the lack of water resistance, the wooden formwork has a short service life and low turnover times; thus, the existing wooden formwork has a large consumption of ...
