Description

Technical Field

[0001] The utility model relates to the technical field of air film systems, in particular to a foldable structure of an air film system. Background Art

[0002] The full name of the air membrane is air-supported membrane structure, which is a new type of building form that has emerged with the development of new materials and new technologies. It uses special building fiber membrane materials as the "shell" and supports the "shell" through an automated pressurization and fresh air system to form an architectural form of building space. It is a new building form that integrates architecture, structural mechanics, new materials, mechatronics, automatic control and other technologies.

[0003] For example, a high-strength air-supported building in a Chinese patent (CN205577113U) includes an inflatable membrane structure and an anchoring structure. The inflatable membrane structure is connected to the ground through the anchoring structure to form a building space with the ground. The air-supported building also includes a steel cable system; the steel cable system covers the outer surface of the inflatable membrane structure and is connected to the anchoring structure to transfer the load borne by the inflatable membrane structure to the anchoring structure. The load borne by the inflatable membrane structure is transferred to the anchoring structure through the steel cable system covering the outer surface of the inflatable membrane structure, thereby greatly improving the load-bearing capacity of the air-supported building and making it possible to build an ultra-large span air-supported building.

[0004] The above scheme also has the following technical deficiencies: the above scheme is not convenient for folding and storing the inflatable membrane structure; the inflatable membrane of the above scheme lacks a fixed folding part when folding and storing, which makes it difficult to ensure that the folding part is the same each time; and the inflatable membrane has a large area, and needs to be folded multiple times when folding. The folded part is subjected to greater force, which can easily cause damage to the inflatable membrane after long-term use. Based on this, a foldable structure of an air membrane system is proposed.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a foldable structure of an air film system, comprising a bottom plate, an air mold mechanism provided on the top side of the bottom plate, an anchor mechanism provided inside the bottom plate, a support mechanism provided on the top side of the air mold mechanism and the anchor mechanism, and a plurality of inflation ports provided on the air mold mechanism;

[0007] The inflatable mold mechanism includes two connecting plates abutting the front and rear ends of the top side of the base plate, a plurality of inflatable membranes are fixed on the top side of the connecting plates, a folding part is fixed between the two inflatable membranes, a first folding groove is opened inside the top side of the folding part, and a plurality of second folding grooves are opened inside the top side of the connecting plate.

[0008] Furthermore, the anchoring mechanism includes multiple groups of anchor rods fixed in a sliding connection inside the base plate, a baffle is fixed on the top side of the anchor rod, a screw is connected to the internal thread of the anchor rod, an extension rod is fixed to the bottom end of the screw, and a cone head is fixed to the bottom end of the extension rod.

[0009] Furthermore, the support mechanism includes a longitudinal steel cable whose two ends are respectively fixed on each group of the anchor rods, a plurality of hanging rings fixed between each two adjacent longitudinal steel cables, a transverse steel cable fixed between the corresponding two hanging rings, and a covering net fixed between two adjacent transverse steel cables, wherein the covering net covers the outer surface of the inflatable membrane.

[0010] Furthermore, the positions of the first folding groove and the second folding groove correspond to each other, and the inflation port is fixed on the inflation membrane.

[0011] Furthermore, a plurality of through holes are provided inside the connecting plate, and the anchor rods can slide in the through holes.

[0012] Furthermore, a connection groove is provided on the outer surface of the anchor rod, and the longitudinal steel cable is wound in the connection groove.

At the same time, multiple inflatable membranes can be inflated separately, thereby improving the inflation efficiency of the inflatable membrane. The first folding groove and the second folding groove can facilitate the folding of the inflatable membrane and the connecting plate to avoid excessive force on the folding part causing damage to the inflatable membrane.
