High-strength formwork for building and manufacturing method thereof

Abstract

The invention relates to a high-strength formwork for a building. The high-strength formwork for the building is characterized by being prepared with, by weight, 100-200g of polyvinyl chloride, 50-60g of coal ash, 50-60g of lignocellulose, 10-15g of sodium hydroxide, 50-60g of water-soluble fluoride resin, 2-10g of antifoaming agent and 60-80g of polymethyl methacrylate. The high-strength formwork for the building has the advantages of being firm, durable, high in strength, good in elasticity and not prone to deforming as the polyvinyl chloride, the polymethyl methacrylate and the fluoride resin are adopted; wood is saved, forest cover is protected against excessive lumbering; the quality of the formwork is improved; after raw materials are mixed, the formwork can be manufactured through a mold according to the shape requirement of an actual building.

Description

technical field [0001] The invention relates to a formwork, in particular to a formwork for construction. The formwork has high strength, low cost and can improve building quality. Background technique [0002] Formwork is an indispensable equipment in construction engineering. Most of the templates currently used in construction projects are wooden or steel templates. It is well known that steel formwork has many disadvantages. The first is high cost, the second is easy to deform, the third is easy to oxidize and rust, the fourth is easy to be corroded, and the fifth is high unit volume weight. The biggest problem with wooden formwork is that it is made of wood, and a large number of trees will increase the amount of forest harvesting, cause damage to the ecological environment, and even cause soil erosion, weakening the ability to resist natural disasters. [0003] In addition, the wooden formwork will absorb water when it is used, which will make the moisture ratio of t...

Problems solved by technology

We all know that steel formwork has many disadvantages. The first is high cost, the second is easy to deform, the third is easy to oxidize and rust, the fourth is easy to be corroded, and the fifth is high unit volume weight.

The biggest problem with wooden formwork is that it is made of wood, and a large number of trees will increase the amount of forest harvesting, cause damage to the ecological environment, and even cause soil erosion, weakening the ability to resist natural disasters

[0003] In addition, the wooden formwork will absorb water when it is used, which will make the moisture ratio of the concrete near the formwork unbalanced, affect its hydration, reduce the surface quality of the concrete structure, and reduce the strength
