Hidden cable snow melting type carbon fiber bundle net gas film structure

Abstract

The invention discloses a hidden cable snow melting type carbon fiber bundle cable net gas film structure which comprises a gas film, a carbon fiber bundle cable, a crossed inhaul cable connecting fastener, a gas film fixing assembly, a cable end fixing assembly, a concrete foundation, an electromechanical system and an access control system, the gas film is fixed to the concrete foundation through the gas film fixing assembly, and a plurality of cable channels are formed in the surface of the gas film; the carbon fiber bundle cable penetrates through the cable channel to be fixed to the surface of the air film, the two ends of the carbon fiber bundle cable are fixed to the concrete foundation through cable end fixing assemblies, the intersection point of the carbon fiber bundle cable is fixed through a crossed inhaul cable connecting fastener, and the carbon fiber bundle cable is connected with a power line arranged along the outer edge of the foundation to form a heating loop. The electromechanical system is used for automatically adjusting the internal pressure of the gas film and supplying power for heating of the carbon fiber bundle cable. Carbon fiber heating and rapid snow removal can be achieved, meanwhile, the cable is embedded into the cable channel, stress is reasonable, the problem of cable film slippage is solved, the weight and the use amount of the cable are reduced, and the wind-resistant and snow-resistant capacity of the air film structure is improved.

Description

technical field [0001] The invention relates to the technical field of air-membrane construction, in particular to a hidden snow-melting carbon fiber bundle mesh air-membrane structure. Background technique [0002] Membrane structure, as a new form of tension structure representing the development level of modern building technology and material science, has the advantages of light weight and high strength, low thermal expansion coefficient, radiation resistance, chemical corrosion resistance and good processing performance, and is widely used in various building structures. . As an important type of membrane structure, air-membrane structure uses high-strength flexible film material, and uses the internal and external pressure difference to support the membrane to cover the large-span space. Now it has become one of the main forms of large-span space buildings. [0003] However, since the membrane can only withstand tension and not compression, when freezing rain or snow ...

Problems solved by technology

For example: "A Snow Removal Device Applied to Building Membrane Structures" 202023208557.4 proposes a snow removal device that automatically sprays tap water and snow-melting agent, and "A Membrane Structure with Snow-melting Function" 201911112807.3 proposes a method of recycling through boiler heating These patents all propose a snow-melting device, but they only spray water or snow-melting agent on the membrane surface to remove snow and ice, consume high energy, and cause harm to the environment. Solve the problem of snow accumulation on the surface, but it may cause ice on the membrane surface, and the snow accumulation will be more serious

In addition, in "Snow Melting Device for Air Film Building" 201510952396.4, although a snow melting device that inflates hot air into the air film is proposed, it requires a multi-layer film structure, which is costly, complex in structure, and troublesome to install.

In addition, a constant temperature electric heating snow removal system is proposed in "A Special Constant Temperature Electric Heating Snow Removal System for Air Film Building" 201620545616.1, but its heating device and induction device are installed on the external protective steel cable, which is not beautiful enough
