Manufacturing technology of plastic formwork for constructional steel plate inserts

Abstract

The invention relates to a plastic formwork of constructional steel plate inserts. The surface of the plastic formwork is smooth and cement-proof, so that surfaces of formed cement works are smooth. The plastic formwork has the same high strength as an iron formwork. The plastic formwork is light in weight, and is as 1 / 2 heavy as the iron formwork. Decay resistance of the plastic formwork is excellent, so that the plastic formwork is especially suitable for constructional use at waterfront and under water. Aging-resistance performance against environment is good, so that the plastic formwork can be thrown from a height of seven floors without damage in the north in winter, and cannot be damaged by beating. When the plastic formwork is used in a normal way, service life of the plastic formwork should not be less than 100 times.

Description

technical field [0001] The invention relates to the technical field of manufacturing construction tools for construction engineering, in particular to "manufacturing technology of steel plate insert plastic formwork for construction". Plastic inserts refer to metal parts embedded in plastic, and the plastic formwork of the present invention is a Embedded with steel plate inserts. 'Plastic formwork with steel plate inserts for construction' is successfully developed by combining all the advantages of the existing iron formwork, overcoming all its shortcomings and integrating all the advantages of the existing plastic formwork, overcoming all the shortcomings. The purpose is to replace the current second-generation building iron formwork as the third-generation building formwork. The so-called replacement must have a complete and superior comprehensive performance, rather than an improvement on a certain point or aspect of the original template. Background technique [0002]...

AI Technical Summary

Problems solved by technology

Plastics also have plasticity, large creep, under force, and will gradually deform over time, so pure plastics cannot be used as building templates; there are also patents declared by domestic people, and some have been approved, such as; ZL01250962.0 "Composite plastic-steel formwork for building construction", this patented formwork is made of metal frame poured with plastic, it only takes advantage of the advantages of plastic, but does not overcome the shortcomings of iron formwork, and there are still exposed metals, which does not solve the problem of iron formwork corrosion, nor does it Solve the problem of iron formwork weight fire; patent ZL93214999.5 "steel-plastic composite formwork", this formwork is basically an iron formwork with a layer of plastic on the surface, which does not solve the three fatal shortcomings of the iron formwork, but sticks cement on the surface There is an improvement, a little improvement
