Abstract

The invention discloses a mixed inflatable film structure in the technical field of building structures. The mixed inflatable film structure comprises an integral supporting film structure, an air bearing film, a film fixing edge, a boot pad, a supporting inflation system and a wrapping inflation system; the integral supporting film structure is fixed on the ground through the boot pad; the air bearing film is wrapped on the integral supporting film structure and fixed on the ground through the film fixing edge; and the integral supporting film structure and the air bearing film are connected with the supporting inflation system and the wrapping inflation system respectively. The mixed inflatable film structure is high in span, high in wind resistance, light and convenient to assemble and disassemble, can be used for a medium or large-span roof structure, and is suitable for multiple flat vertical building space layouts.

Description

technical field [0001] The invention relates to a device in the technical field of building structures, in particular to a hybrid inflatable membrane structure. Background technique [0002] The membrane structure began in 1952, and its typical forms are skeleton membrane, tensile membrane, air-bearing membrane and airbag membrane. Through cable tensioning and stabilizing the membrane, the air-bearing membrane is inflated to generate a pressure difference between the inside and outside of the building space to support the building membrane, and the airbag membrane is inflated to make the air chamber generate a pressure difference between the inside and outside to maintain the rigidity of the airbag for building structures. These structures are used Extensive research, among which: skeleton membrane and tensile membrane technology is mature and widely used at home and abroad. In the early days, the air-bearing membrane was a high-sag roof, such as the early radar dome in the...
