Plastic building template and manufacturing process

Abstract

The present invention relates to a plastic building form and its production method. Said invention adopts the waste plastics as raw material, and adopts the production processes of pug milling, mixing by using mill mixer, cooling, pressing and secondary cooling to obtain a plastic sheet. Said plastic sheet and wood chip can be alternately superimposed, heated and pressurized, and integrally-formed into the invented plastic wood composite form, and the above-mentioned plastic sheet and bamboo net also can be alternately superimposed, heated, pressurized and integrally-formed into the invented plastic bamboo composite form.

Description

technical field [0001] The invention relates to building materials, in particular to a plastic building formwork and its production process, especially to a plastic building formwork and its production process for the pre-casting of building reinforced concrete components. Background technique [0002] As we all know, according to the traditional construction technology, an average of about 2.65 square meters of building formwork is required per square meter of construction area, and the amount of wood consumed per 100 square meters of formwork: about 7.4 cubic meters for one-time use; When it is reused five times, it also needs to use 1.5 cubic meters; due to the high waste and damage when assembling or disassembling the formwork, it can only be reused two or three times in general, so in actual construction projects, natural resources such as bamboo and wood The consumption is extremely alarming; if steel formwork is used, its assembly and disassembly are also very trouble...

[0002] As we all know, according to the traditional construction technology, an average of about 2.65 square meters of building formwork is required per square meter of construction area, and the amount of wood consumed per 100 square meters of formwork: about 7.4 cubic meters for one-time use; When it is reused five times, it also needs to use 1.5 cubic meters; due to the high waste and damage when assembling or disassembling the formwork, it can only be reused two or three times in general, so in actual construction projects, natural resources such as bamboo and wood The consumption is extremely alarming; if steel formwork is used, its assembly and disassembly are also very troublesome, and in large-scale construction projects, storage is also very inconvenient;

[0003] At present, the formwork structure and materials used at home and abroad have made great progress. The problem of punching holes in the formwork has not been solved well. The formwork is damaged after being punched, especially the bamboo formwork and plywood formwork. The cement slurry in the concrete is corroded, the formwork is easily deformed, the gap between the formwork and the tension bolts is filled with cement slurry, and when the formwork is removed, the tension bolts have a great resistance, the formwork surface is destroyed quickly, and the designed number of times cannot be used, and The flatness is not good, it is easy to crack, and the service life is short, which urgently needs to be improved
