Combined type plastic board formwork

Abstract

The invention discloses a combined type plastic board formwork, which comprises a plurality of plastic boards. Plastic board concave and convex cases are uniformly distributed on the plastic boards, and side ribs are disposed on four sides of each plastic board; the side ribs of the plastic boards are connected with steel frames; the steel frames comprise transverse steel frames and longitudinal steel frames; and the plastic boards are connected via U-shaped pins. The combined type plastic board formwork has the advantages of high integral rigidity and bearing ability, simple structure, convenience in operation, reusability and the like; shortcomings of all-metal or all-plastic formworks are overcome, and the large-width combined type formwork is manufactured by means of respective advantages of an all-metal formwork and an all-plastic formwork; the combined type plastic board formwork can be used for various concrete structures, and is particularly used for horizontal form erecting of floors, erecting and disassembling are fast, labor is saved, concrete surfaces are smooth, and turnover frequency is high; the turnover frequency of the combined type plastic board formwork is higher than the turnover frequencies of a steel mold and a combined board, the combined type plastic board formwork has the advantages of zero pollution, corrosion resistance, durability, easiness in demolding and the like, the boards can be replaced and recycled, and comprehensive economic benefits including energy conservation, environmental protection and the like are realized.

Description

technical field [0001] The invention relates to a formwork structure of cast-in-place concrete components, in particular to a combined plastic plate formwork, which belongs to the construction field. Background technique [0002] As a new type of building formwork, plastic formwork has the characteristics of good concrete surface forming effect, energy saving and environmental protection, and recyclability, but it also has low strength and rigidity, low bearing capacity, large coefficient of thermal expansion and contraction, and is less affected by temperature changes. Large and other shortcomings have hindered the popularization and application of plastic formwork in engineering. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a combined plastic panel formwork, which improves the rigidity of the panel surface and reduces the weight of the formwork, thereby reducing t...
