Embodiment 1

[0046] The air-film thermal insulation structure adapting to changes in air pressure provided by the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. figure 1 As shown, the air film insulation structure provided in this embodiment includes an air film 2, a first differential pressure sensor 3, a first pressurizing device 5 and a control system.

[0047] Specifically, a base body 1 is pre-formed on the ground. The base body 1 may be formed by pouring concrete or a counterweight object. The edge of the air film 2 is sealed on the base body 1 to define a building space 10 below the air film 2 .

[0048] The first differential pressure sensor 3 is installed on the gas film 2, and one gas pipe is connected to the inside of the gas film 2, and one gas pipe is connected to the outside of the gas film 2, and is used to measure the pressure difference between the gas pressure inside the gas film 2 and the atmospheric pre...

Embodiment 2

[0089] This embodiment provides a construction method for constructing the air-film thermal insulation structure described in the embodiment, which specifically includes the following steps:

[0090] First, seal and fix the edge of the air film 2 to the base body 1 and define the building space 10;

[0091] Then, the air is inflated into the building space 10 to expand the air film 2 , and a thermal insulation sticker is attached to the inner wall of the air film 2 .

[0092] As a further improvement of the present embodiment, the building space 10 is inflated with air before attaching the thermal insulation layer to make the pressure difference between the inside of the building space 10 and the outside of the building space 10 greater than the preset pressure difference; A plurality of flexible heat insulating sheets 11 are attached to form a heat insulating layer, and finally the pressure in the building space 10 is reduced, so that the pressure difference between the build...

Abstract

The invention provides an air-film thermal insulation structure adaptable to changes in air pressure, which includes an air film whose edges are sealed on a substrate to define a building space; and a heat-insulating layer that is pasted on The inner wall of the gas film; the first differential pressure sensor measures the pressure difference between the gas pressure in the gas film and the atmospheric pressure outside the gas film; the first pressurizing device, the first pressurizing device is connected with the building space, Inflate the building space; control system, the control system is respectively connected with the first differential pressure sensor and the first pressurizing equipment; the control system controls the first pressurizing equipment to enter the building space according to the value measured by the first differential pressure sensor The speed of inflation keeps the gas pressure inside the air film and the atmospheric pressure outside the air film at the preset pressure difference. The invention can ensure the support of the air film to the building main body.

Description

technical field [0001] The invention relates to an air-film building, in particular to an air-film thermal insulation mechanism and a construction method adapting to changes in air pressure. Background technique [0002] In stadiums, warehouses, industrial plants, cold storage and other scenarios, air membranes are often used as building shells, equipped with a set of intelligent electromechanical equipment to provide positive pressure in the building space inside the air membranes to support the main body of the building. [0003] When using the air film as the building shell, it is necessary to ensure that the pressure of the building space inside the air film is higher than the atmospheric pressure outside, otherwise the main body of the building cannot be supported. However, in some extreme environments, temperature changes will cause pressure changes, so that the pressure in the building space inside the air film is lower than the atmospheric pressure outside, so that t...
