Embodiment 1

[0046] The air film heat preservation structure adapting to changes in air pressure provided by the embodiments of the present invention will be described in detail below in conjunction with 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 preformed on the ground, and the base body 1 may be formed by pouring concrete, or may be 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 membrane 2, one of its gas pipes communicates with the inside of the gas membrane 2, and one gas pipe communicates with the outside of the gas membrane 2, and is used to measure the pressure difference between the gas pressure inside the ga...

Embodiment 2

[0089] This embodiment provides a construction method for building the air film insulation structure described in the embodiment, which specifically includes

[0090] First sealing and fixing the edge of the air film 2 to the base 1 and defining the building space 10;

[0091] Then inflate the building space 10 to make the air film 2 expand, and install a thermal insulation layer on the inner wall of the air film 2 .

[0092] As a further improvement of this embodiment, first inflate the building space 10 so that the pressure difference between the building space 10 and the outside of the building space 10 is greater than the preset pressure difference before attaching the heat insulation layer; A plurality of flexible heat insulating sheets 11 are pasted to form a heat insulating layer, and finally the pressure inside the building space 10 is reduced, so that the pressure difference between the inside of the building space 10 and the outside of the building space 10 is mainta...

Abstract

The invention provides an air film heat preservation structure adapting to air pressure change. The air film heat preservation structure comprises an air film, a heat insulation pasting layer, a first differential pressure sensor, first pressurizing equipment and a control system, wherein the edge of the air film is sealed on a base body to define a building space; the heat insulation pasting layer is pasted on the inner wall of the air film; the first differential pressure sensor is used for measuring the differential pressure between the air pressure intensity in the air film and the atmospheric pressure intensity outside the air film; the first pressurizing equipment is connected with the building space and is used for inflating the building space; the control system is connected with the first differential pressure sensor and the first pressurizing equipment; and the control system controls the speed of the first pressurizing equipment for inflating the building space according to the numerical value measured by the first differential pressure sensor, so that the air pressure intensity in the air film and the atmospheric pressure intensity outside the air film are always maintained under the preset differential pressure. The air film heat preservation structure has the advantage that the support of the air film on a building main body can be ensured.

Description

technical field [0001] The invention relates to an air-film building, in particular to an air-film heat preservation mechanism and a construction method adaptable 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, which 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 greater than the external atmospheric pressure, otherwise the main body of the building cannot be supported. However, in some extreme environments, temperature changes will cause pressure changes, which will cause the pressure in the building space inside the air film to be lower than the outside atmospheric p...
