Building formwork cast in engineering plastic

Abstract

The invention discloses a building formwork cast in engineering plastic. The joint between the formworks is of a structure with one concave portion and two protrusions, the bottom face of the joint is provided with a supporting protruding flat face, cement paste is prevented from flowing out of a gap, and the quality of the surface of a cast product is improved. PPR materials are used, and therefore cement paste can be more easily removed from the formwork. Meanwhile, corrosion which is caused by cement paste to the formwork is reduced, and the service life of the formwork is prolonged. The engineering plastic is used, and therefore production cost is reduced, the weight of the formwork is reduced, and the formwork is convenient to transport and use. During the popularization and application of the technology, the building formwork is a revolution in building construction history and has great significance.

Description

technical field [0001] The invention relates to the construction industry, and directly relates to an engineering plastic casting and forming building formwork. [0002] Background technique [0003] When building a large building, the construction components of the building must be poured on site, and the construction formwork is generally used to form the model of the construction components. Therefore, the construction formwork is an important tool in the construction industry. When pouring slabs or cement beams, since there is no protrusion at the bottom between the square steel formworks that are currently in the market, the cement slurry will flow out from the joints of the traditional steel formwork, so that the poured cement components will be uneven, affecting the quality of the components. At the same time, the traditional steel formwork is easy to be stained with cement and difficult to clean. Due to the corrosion of cement, the service life of the traditional s...
