Construction method with space gas film as formwork

Abstract

The invention relates to a construction method with a space gas film as a formwork. A gas film formwork is machined and formed in a factory according to project design, the gas film formwork is transported to a construction site after being machined, before the gas film formwork is fixed and inflated, a hydraulic crane, building materials and building equipment are transported into the gas film formwork and cover correct positions, the gas film formwork is unfolded and fixed to a foundation, the gas film formwork is inflated, and the hydraulic crane, the building materials and the building equipment are located on the floor inside a building of the gas film formwork after the gas film formwork is formed; after the gas film formwork is installed and inflated, air pressure in a bin is kept stable, polyurethane foam is sprayed onto the inner surface of the gas film formwork to form a polyurethane layer, constructional steel bars and wall structure steel bars are bound to the surface of the polyurethane layer, concrete is sprayed layer by layer to form reinforced concrete layers, when the concrete reaches the designed strength, an inflating fan is shut down, holes are formed in walls, and subsequent construction processes are carried out. Compared with a traditional construction method, the construction method with the space gas film as the formwork has the advantages that the construction period is short, labor and material are saved, the energy consumption rate is low, the safety coefficient is high, the external shape is beautiful, and seamless connection of the overall structure can be achieved.

Description

technical field [0001] The invention relates to a construction method of a large-capacity storage bin, in particular to a construction method using a space air film as a template. Background technique [0002] The construction of traditional buildings such as long-span and large-capacity storage warehouses requires a large amount of wood formwork, steel formwork, etc., a lot of auxiliary materials, and a long construction period, high energy consumption rate, and low safety factor. Contents of the invention [0003] The purpose of the present invention is to provide a construction method using space air film as a formwork, which solves the defects of the traditional construction method using wood formwork and steel formwork, many turnover materials, long construction period, high labor cost and low safety factor. [0004] The purpose of the present invention is achieved in the following manner: according to the specifications and models designed by the construction project...
