Embodiment Construction

[0031] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0032] The invention provides a construction technology of air film concrete construction formwork, specifically:

[0033] 1) Cut the membrane material 1 into sheets after calculating according to the shape of the building;

[0034] 2) After the membrane material 1 is cut, it is seamlessly spliced ​​into the shape of the building by using high-speed friction; mainly using the high-frequency principle to apply the membrane material 1 between the upper and lower poles of a high-frequency electromagnetic field, so that the internal molecules are intensified and high-speed motion rubs against each other to generate heat and melt. Welding is achieved under mold pressure.

[0035] 3) Fix the formed membrane material 1 on the ring beam of the building foundation, and then use air supply equipment to press air into the inside of the membrane material 1, so tha...

Abstract

The invention discloses a gas film concrete construction formwork construction technology. The technology comprises the steps that 1, a membrane material is calculated according to the shape of a building and then cut into flakes; 2, the membrane material is cut and then spliced into the shape of the building seamlessly by means of high-speed friction; 3, the formed membrane material is fixed to abuilding foundation ring beam, air is pressed into the membrane material through air supply equipment, and the pressure difference is generated inside and outside the membrane material; 4, after themembrane material inflates to reach the preset building shape, a polyurethane insulating layer is sprayed to the membrane material; 5, after the membrane material is formed through polyurethane insulating layer hardening, concrete is sprayed to the surface of the membrane surface, and a gas film concrete construction formwork is obtained. The gas film concrete construction formwork construction technology has the advantages of being easy to manufacture and form, prefabricated forming can be achieved, and the special-shaped cambered surface is made very easily.

Description

technical field [0001] The invention relates to a concrete special-shaped curved surface formwork, in particular to a construction process of an air film concrete construction formwork. Background technique [0002] At present, most of the domestic market uses wooden formwork or steel formwork for concrete pouring operations. Wooden formwork is prone to deformation or even mold explosion, resulting in uneven poured concrete and affecting the quality of the project. The steel mold is heavy, inconvenient to disassemble and assemble, and the cost is relatively high, so it is troublesome to reuse. The above two templates are very difficult to make special-shaped and curved surfaces. [0003] The purpose of this invention is to solve the core problems such as difficulty in making special-shaped concrete formwork and inconvenient disassembly and assembly. Using high-strength film as a formwork, the concrete formwork can be made into a special-shaped surface to meet the needs of m...
