Problems solved by technology

[0002] At present, the building formwork on the market is generally made of metal materials. The disadvantage of this building formwork is that the formwork is easy to rust, the formwork is firmly bonded to the concrete after use, the formwork is difficult to remove, and the formwork must be oiled before use. The oiled concrete needs to be polished before painting, otherwise the painted cement or paint will easily peel off
In addition, the surface of the concrete made with metal formwork is rough and needs secondary external powder. In order to overcome the above defects, it is necessary to develop a plastic-steel building formwork to replace the existing metal building formwork.

Abstract

A manufacturing method of a plastic steel building template adopts an intra-mould injection molding method to produce the plastic steel building template. The intra-mould injection molding method comprises placing a metal building template in a mould of an injection moulding machine, and utilizing plastic particles to produce the plastic steel building template by injection moulding in the injection moulding machine. Metal template portions of the produced plastic steel building template are totally covered by plastic materials, and the plastic steel building template has rigidity of a metal template and has the advantages of corrosion resistance, shock resistance and avoidance of adhesion to concrete of a nonmetal material. The plastic steel building template is lighter than a metal steel template, resistant to corrosion and free of rust, the surface of the template does not need oil coating, and the surface of the concrete cast by the plastic steel building template is smooth so that external whitewash is not needed.

Description

technical field [0001] The invention belongs to the technical field of building materials, and relates to a method for manufacturing a plastic-steel building formwork. Background technique [0002] At present, the building formwork on the market is generally made of metal materials. The disadvantage of this building formwork is that the formwork is easy to rust, the formwork is firmly bonded to the concrete after use, the formwork is difficult to remove, and the formwork must be oiled before use. The oiled concrete needs to be sanded before it can be painted, otherwise the painted cement or paint will easily peel off. In addition, the surface of the concrete made with metal formwork is rough and needs secondary external powder. In order to overcome the above defects, it is necessary to develop a plastic-steel building formwork to replace the existing metal building formwork. Contents of the invention [0003] The purpose of the present invention is to provide a manufactu...
