Abstract

The invention discloses a double-layer differential-pressure air-supported membrane structure. The double-layer differential-pressure air-supported membrane structure comprises an inner membrane and an outer membrane which are arranged on a bottom surface in an arched manner. A sealed inner membrane cavity is formed between the inner membrane and the bottom surface. A sealed double-layer membrane sandwich cavity is formed among the outer membrane, the inner membrane and the bottom surface. A communicating device is arranged between the inner membrane cavity and the double-layer membrane sandwich cavity. The communicating device comprises an inner-membrane ventilation hole formed in the top of the inner membrane and a sandwich ventilation pipe arranged in the double-layer sandwich cavity. The air inlet end of the sandwich ventilation pipe is connected with the inner-membrane ventilation hole. The air outlet end of the sandwich ventilation pipe is arranged at the bottom of the double-layer membrane sandwich cavity. A fan arranged outside the outer membrane supplies air for the inner membrane cavity. The pressure intensity of the inner membrane is larger than that of the outer membrane. The pressure intensity of the outer membrane is larger than the intensity of atmospheric pressure outside the outer membrane. The double-layer differential-pressure air-supported membrane structure has the advantages that the stability of the double-layer membrane structure is achieved through pressure intensity difference, and the double-layer differential-pressure air-supported membrane structure is convenient to mount and high in safety.

Description

technical field [0001] The invention relates to the field of air-film architecture, in particular to a double-layer differential pressure air-supported membrane structure. Background technique [0002] The membrane structure is a curved space structure with a certain rigidity and a certain external load that is formed by combining high-strength flexible film material and a support system. The membrane structure is divided into skeleton membrane structure, tensile membrane structure and inflatable membrane structure. The inflatable membrane structure is further divided into an air-finned membrane structure and an air-supported membrane structure. The air-supported membrane structure is fixed on the basic structure with the membrane material as the shell, and only relies on the air supply system to maintain a certain pressure inside the membrane to form, and has a certain rigidity to resist external forces. The existing air-bearing membrane structure generally adopts double-...
