Description

Technical Field

[0001] The present invention belongs to the technical field of inflatable equipment, and particularly relates to an inflatable structure of an air-supported membrane structure. Background Art

[0002] The inflatable membrane structure is a special form of the membrane structure. By applying air pressure on the membrane surface, prestress is introduced to generate structural stiffness sufficient to resist external loads. Research shows that generally, only when the indoor air pressure is increased by 25 Pa compared to the atmospheric pressure, can the inflatable membrane expand to form a certain curved shape to support the membrane surface. The inflatable membrane can be supported on other building structures to form an auxiliary enclosure, or can form an independent building body.

[0003] In recent years, the environmental protection standards of domestic industrial enterprises have been continuously improved. Laws and regulations of government departments at all levels also clearly require the full enclosure of industrial sites with relatively large pollution and more exhaust gas emissions. The enclosed space made of membrane materials, after being fixed and inflated, is equipped with a special cable system to become a closed building that can resist wind, frost, rain, and snow. The internal pressure is the core factor for the structure to form stiffness and maintain stability. At the same time, it can also be used as a long-term load to maintain the reasonable stiffness of the structure under external loads and adjust the structure form. If the internal pressure is not controlled stably, it may cause snow accumulation and water accumulation on the outer membrane, and excessive deformation and membrane material failure and wrinkling may occur under long-term pressure.

[0004] In a harsh environment, the existing air-supported membrane is prone to aging under strong light and high temperature. Once it needs to be replaced, the roof needs to be directly disassembled to install a new air membrane, which has a great impact on the use of the venue, and even makes the venue unable to be used directly during the construction process. Summary of the Invention

[0005] In order to solve the technical problems that the air-supported membrane structure is difficult to achieve effective support in extreme rain and snow weather and the air-supported membrane structure is difficult to ensure the indoor temperature in severe cold in the prior art, the present invention provides a multi-layer air-supported membrane hollow hall that can effectively break ice and snow and prevent water accumulation.

[0006] To achieve the above object, the technical solution adopted by the present invention is: a multi-layer air-supported membrane hollow hall, including a first annular support wall and a first air-supported membrane. The first annular support wall is fixed on the base body. A first membrane installation ring beam is arranged at the top edge of the first annular support wall. The first air-supported membrane is fixed on the first membrane installation ring beam. The first air-supported membrane, the first annular support wall and the base body jointly enclose a hollow venue.

[0007] It further includes a second annular supporting wall and a second air-supported membrane. The second annular supporting wall is fixed to the base body. A second membrane-installing ring beam is arranged at the top edge of the second annular supporting wall. The second air-supported membrane is fixed to the second membrane-installing ring beam. The second annular supporting wall is arranged outside the first annular supporting wall, and there is a certain interval space between the first annular supporting wall and the second annular supporting wall. The second air-supported membrane is arranged above the first air-supported membrane. The first annular supporting wall, the second annular supporting wall, the first air-supported membrane, the second air-supported membrane and the base body jointly enclose an isolation protection chamber.

[0008] A plurality of third air-supported membranes are arranged at the top of the second air-supported membrane. An air valve is arranged in the third air-supported membrane. The air valve connects the second air-supported membrane and the third air-supported membrane. A channel for fluid to pass through is formed between adjacent third air-supported membranes.

[0009] A first air blower is arranged outside the first annular supporting wall, and the air outlet of the first air blower extends into the hollow venue.

[0010] A second air blower is arranged outside the second annular supporting wall, and the air outlet of the second air blower extends into the isolation protection chamber.

[0011] The height difference between the vertex of the second air-supported membrane and the vertex of the first air-supported membrane is not less than 0.1 m.

[0012] The third air-supported membrane and the second air-supported membrane are compacted by an aluminum pressing plate.

[0013] The air pressure in the isolation protection chamber is less than the air pressure in the hollow venue, and the difference between the air pressure in the isolation protection chamber and the air pressure in the hollow venue is 20 - 50 Pa.

[0014] The hollow venue further includes an intelligent pressure regulating system, which includes a main blower arranged at the air inlet of the air inlet pipe, a standby blower arranged in the air inlet pipe, an air inlet regulating component arranged in the air inlet pipe, a return air regulating component arranged in the return air pipe, a pressure regulating alarm device and a pressure regulating communication device. The pressure regulating alarm device and the pressure regulating communication device are both electrically connected to the controller.

[0015] The intelligent pressure regulating system further includes an electric control louver arranged at the air outlet. The electric control louver is electrically connected to the controller. By intelligently controlling the opening and closing of the electric control louver, the air intake volume can be adjusted to adjust the internal pressure of the air-supported membrane.

[0016] The hollow venue further includes an intelligent air-conditioning regulating system, which includes an air-conditioning unit and a pressure sensor, a temperature sensor, an air-conditioning alarm device and an air-conditioning communication device arranged in the isolation protection chamber. The air-conditioning alarm device and the air-conditioning communication device are both electrically connected to the controller.

[0017] A pressure sensor is arranged in the second air-supported membrane, and a pressure sensor is arranged in the third air-supported membrane.

[0018] The hollow venue is equipped with a pressure detection device and a safety valve. The safety valve connects the hollow venue with the external atmosphere, and both the pressure detection device and the safety valve are electrically connected to the controller.

[0019] Compared with the prior art, the specific beneficial effects of the present invention are as follows:

[0020] First, the present invention arranges a plurality of third air-bearing membranes at the top. When snow and ice accumulate on the roof, the third air-bearing membranes bulge, increasing the outer surface curvature of the entire air film structure and raising the temperature inside the third air-bearing membranes. The snow and ice break and melt, and the water drains quickly, improving the ability to resist snow pressure and wind pressure in extreme climates.

[0021] Second, the present invention adopts a membrane roof structure with three air films. The protective isolation chambers between adjacent air films can play a role in hollow heat preservation and constant temperature for the interior, improving the heat preservation and energy-saving effect of the interior of the air film building.

[0022] Third, the present invention adopts a membrane roof structure with three layers of air-bearing membranes. The outermost outer membrane can be replaced at any time according to the surface aging degree and the need for color tone change, without affecting the normal use of the interior, and without affecting the air film building structure.

[0030] A plurality of third air-supported films 10 are arranged on the top of the second air-supported film 8. An air valve 11 is arranged inside the third air-supported film 10. The air valve 11 connects the second air-supported film 8 and the third air-supported film 10. A channel for fluid to pass through is formed between adjacent third air-supported films 10.

[0031] A first air blower 12 is arranged outside the first annular support wall 1. The air outlet of the first air blower 12 extends into the hollow stadium 5.

[0032] A second air blower 13 is arranged outside the second annular support wall 6. The air outlet of the second air blower 13 extends into the isolation protection chamber 9.

[0033] The height difference between the vertex of the second air-supported film 8 and the vertex of the first air-supported film 3 is not less than 0.1 m.

[0034] The third air-supported film 10 and the second air-supported film 8 are compacted by an aluminum pressing plate.

[0035] The air pressure in the isolation protection chamber 9 is less than the air pressure in the hollow stadium 5. The difference in air pressure between the isolation protection chamber 9 and the hollow stadium 5 is 20 - 50 Pa, making the hollow stadium 5 and the isolation protection chamber 9 completely independent.

[0036] The hollow hall also includes an intelligent pressure regulating system, which includes a main fan arranged at the air inlet of the air inlet duct, a standby fan arranged in the air inlet duct, an air inlet regulating component arranged in the air inlet duct, a return air regulating component arranged in the return air duct, a pressure regulating alarm device and a pressure regulating communication device.

[0037] The intelligent pressure regulating system also includes an electric control louver arranged at the air outlet, and the electric control louver is electrically connected to the controller. The opening and closing of the electric control louver are intelligently regulated to adjust the air intake volume to adjust the internal pressure of the air film.

[0038] The hollow hall also includes an intelligent air-conditioning control system, which includes an air-conditioning unit and a pressure sensor, a temperature sensor, an air-conditioning alarm device and an air-conditioning communication device arranged in the isolation protection room 9. Both the air-conditioning alarm device and the air-conditioning communication device are electrically connected to the controller.

[0039] A pressure sensor is arranged in the second air-supported membrane 8 to monitor the pressure inside the second air-supported membrane 8 through the pressure sensor; a pressure sensor is arranged in the third air-supported membrane 10 to monitor the pressure inside the third air-supported membrane 10 through the pressure sensor.

[0041] The specific working process of the present invention is as follows: According to the monitored weather conditions, when it is monitored that there is a severe heat situation, the intelligent air-conditioning control system intelligently adjusts the air inlet temperature and air intake volume, and the intelligent air-conditioning control system sends cold air to control the temperature in the hollow venue 5 to a comfortable temperature; when there is a severe cold weather, the intelligent air-conditioning control system intelligently adjusts the air inlet temperature and air intake volume to control the temperature in the hollow venue 5 to a comfortable temperature; when there is a heavy rain weather, due to short-term rapid precipitation, water accumulation, wrinkles are likely to appear on the membrane top, and even the situation of collapse may occur. The intelligent pressure regulating system is started, the air valve 11 is opened, and the gas in the second air-supported membrane 8 enters the third air-supported membrane 10 through the air valve 11. The third air-supported membrane 10 bulges, and a channel for rainwater to pass through is formed between adjacent third air-supported membranes 10, and the rainwater is quickly discharged to ensure the stability and safety of the air-supported membrane structure; when there is snow accumulation, the intelligent pressure regulating system is started, the air valve 11 is opened, and the gas in the second air-supported membrane 8 enters the third air-supported membrane 10 through the air valve 11. The third air-supported membrane 10 bulges and forms a bulge. The temperature of the gas between the first air-supported membrane 3 and the second air-supported membrane 8 rises, and the ice and snow on the outer membrane surface break and quickly melt, and the snow water is discharged through the channels connecting adjacent third air-supported membranes 10, improving the resistance of the air-supported membrane building in extreme climates.

[0042] When it is detected that the pressure in the hollow venue 5 is too low, the intelligent air conditioning system is used to adjust the regulation of cold and hot air, and the control information is fed back to the intelligent pressure regulating system, and then the opening and closing of the air inlet valve and the air return valve are adjusted to adjust the air pressure in the hollow venue 5.

[0043] When the alarm system alarms, the intelligent pressure regulating system adjusts the pressure and temperature according to the alarm information.

[0044] When the pressure is too high, the safety valve automatically opens to release the pressure in time to ensure the safety of the air film building.

[0045] The present invention adopts a film top structure of three-layer air-supported membranes. The outermost outer film can be replaced at any time according to the surface aging degree and the need for color tone change, without affecting the normal use indoors and without affecting the air film building structure.

[0046] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the scope of the present invention.
