Problems solved by technology

[0003] However, the surface of the concrete shell is a curved surface, the construction of cast-in-place concrete is difficult, the material and manpower consumption is large, and the construction cost is high. In recent years, it has been gradually replaced by the steel reticulated shell structure

Abstract

The invention discloses a manufacturing method of a prefabricated gas film concrete shell. The manufacturing method includes a prefabrication stage, a planar assembly stage, an inflation jacking stage and a spatial assembly stage. The invention further discloses the prefabricated gas film concrete shell. The prefabricated gas film concrete shell comprises a block assembly, a tie grid and surface layer concrete, wherein the block assembly, the tie grid and the surface layer concrete form a shell body of the prefabricated gas film concrete shell, the tie grid is laid on the outer side of the block assembly, and the surface layer concrete is poured on the outer side of the tie grid. The prefabricated gas film concrete shell has the advantages that the manufacturing method is simple, precision is high, material and manpower consumption is small, and building cost is low, and can be applied to prefabricated structures in the fields of buildings, bridges, water projects and the like.

Description

technical field [0001] The invention relates to a concrete shell, in particular to a prefabricated assembled air film concrete shell and a manufacturing method thereof, which belong to the technical field of civil engineering and can be applied to prefabricated assembled structures in the fields of buildings, bridges, water conservancy projects and the like. Background technique [0002] Concrete shell is a structural form with excellent mechanical properties, and was once widely used in long-span engineering structures. The concrete shell uses the compressive performance of the material to resist external loads. The bending moment and shear force in the shell are very small, so it can give full play to the characteristics of the good compressive performance of concrete, and it is considered to be the most reasonable concrete structure. [0003] However, the surface of the concrete shell is a curved surface, the construction of cast-in-place concrete is difficult, the materi...
