Embodiment 1

[0024] Such as figure 1 , figure 2 As shown, the present invention is used in public and civil buildings. The shell structure includes a reinforced concrete layer 3, an air film layer 1, and the air film layer 1 is located outside the reinforced concrete layer 3, and the air film layer 1 and the reinforced concrete layer 3 are fixedly integrated. It also includes an insulation layer 2, the insulation layer 2 is located between the air film layer 1 and the reinforced concrete layer 3, and the insulation layer 2 is made of polyurethane material.

[0025] During construction, the air film layer 1 is constructed first, the air film is processed in the factory, and the film is blown by a blower on site; then the insulation layer 2 is made on the inner side of the air film layer 1, and the polyurethane material is sprayed on the inner side of the air film layer 1 to form an insulating layer ; Next, construct the reinforced concrete layer 3 on the inner side of the insulation laye...

Embodiment 2

[0027] Such as figure 2 , image 3 Shown, the present invention is used for industrial warehouse engineering. First construct the ring base 7; then carry out the construction of the ring wall 8 and the conveying corridor 9; then fix the air film on the ring wall by pre-embedding parts, and carry out the construction of the air film layer 10: the air film is processed in the factory, and the blower is used to blow the film on site Forming; then make the insulation layer 11 in the air film layer 10, and spray polyurethane material on the inside of the air film layer 10 to form the insulation layer 11; then construct the reinforced concrete layer 12 on the inside of the insulation layer 11: adopt a car crane for vertical transportation Tools, tying steel bars, layered shotcrete, finally forming a long-span reinforced concrete layer structure; finally, the filling of the funnel 13 and the construction of the roof platform 14 are carried out.

Abstract

The invention relates to an air-film reinforced concrete shell structure of a building and a construction method. The structure comprises a reinforced concrete layer; the structure is characterized by further comprising an air film layer which is located on the outer side of the reinforced concrete layer, and the air film layer and the reinforced concrete layer are fixedly connected into a whole; when construction is conducted, an air film is machined firstly, then a polyurethane material is sprayed to the inner side of the air film to form an insulating layer, and finally reinforcements are banded and concrete is sprayed in a layered mode on the inner side of the insulating layer to form the reinforced concrete.

Description

technical field [0001] The invention relates to an air film reinforced concrete shell structure of a building and a construction method. Background technique [0002] In the prior art, the air-film structure used in buildings has the advantages of fast construction speed and large span, but poor durability and poor thermal insulation; although the reinforced concrete structure is strong and durable, it is difficult to construct a large-span structure. Contents of the invention [0003] The object of the present invention is to provide an air-film reinforced concrete shell structure and construction method of a building. The shell structure has fast construction speed and is durable. [0004] Based on the same inventive concept, the present invention has two independent technical solutions: [0005] 1, a kind of air film reinforced concrete shell structure of building, comprise reinforced concrete layer, it is characterized in that: also comprise air film layer, air film l...
