Problems solved by technology

Its advantage is that it can save a lot of wood, and can be reused many times. The turnover rate can reach 40 times. Weight limit, the area of ​​a single formwork is not large, and the number of splicing pieces in use is time-consuming and laborious; ④Steel formwork has a certain affinity with cement, and it is easy to scratch the surface of cement products such as columns or beams when disassembling the formwork, which affects the quality ; ⑤ steel formwork is easy to rust.

Abstract

The invention relates to the technical field of building templates, in particular to a novel PVC (polyvinyl chloride) board, the novel PVC board comprises a plant fiber base layer, and a resin layer covers the plant fiber base layer, the novel PVC board has the advantages that, the template has excellent characteristics of wood and plastic, and the produced product achieves the effect of really imitating the wood. Moreover, no toxic substances such as formaldehyde are avoided.

Description

technical field [0001] The invention relates to the technical field of building templates, in particular to a novel PVC board. Background technique [0002] Formwork engineering refers to a formwork formed by newly poured concrete and a complete set of structural systems to support the formwork. Among them, the structural part that touches the concrete and controls the predetermined size, shape and position is called the formwork; the rods, trusses, couplings, metal accessories, working bridges, etc. that support and fix the formwork constitute the support system; for the sliding formwork, the jack-up formwork is Increase the lifting power, lifting frame, platform and other components. Form work is a temporary structure in concrete construction. [0003] Commonly used building templates include bamboo plywood and steel formwork. Bamboo plywood was the earliest application. It uses moso bamboo as the main structure and filling material. Because it consumes a lot of wood, an...
