Description

Technical Field

[0001] This utility model belongs to the field of air-supported membrane structure buildings, and in particular relates to an air-supported membrane structure building that includes a fire sprinkler system. Background Technology

[0002] Air-supported membrane structures, made of flexible membrane materials, present several challenges when installing fire protection systems, such as fire sprinkler pipes. These challenges include the weight of metal pipes, difficulties in connecting them to the main structure, and the proper pipe layout. Traditionally, this involves erecting supports on the ground for individual fixing. For example, the air-supported membrane sprinkler structure and building disclosed in CN206964939U, while utilizing traditional methods, occupies valuable interior space. Furthermore, large-scale air-supported membrane structures requiring steel supports for fire pipes while maintaining structural strength necessitate substantial steel resources. In extreme weather conditions such as strong winds and heavy snow, the membrane structure may shift, making it unsuitable for rigid steel supports (fire pipes). Installing fire pipes across large spans is also impractical, contradicting the inherent advantages of air-supported membrane structures: low cost and rapid construction. Utility Model Content

[0003] (1) Technical problem to be solved: an air-supported membrane structure building containing a fire sprinkler system.

[0004] (2) The technical solution adopted by this utility model is as follows:

[0005] An air-supported membrane structure building including a fire sprinkler system includes an air-supported membrane structure main body. Fluid channels formed by membrane fabric are provided on the inner wall of the air-supported membrane structure main body. The membrane fabric is fixedly connected to the inner wall of the air-supported membrane structure main body. Multiple sprinkler heads are evenly distributed on the fluid channels. The multiple fluid channels are evenly distributed on the inner wall of the air-supported membrane structure main body and are connected to a main pipe. The main pipe is connected to a water supply device.

[0006] A further technical solution is that the end of the fluid channel is connected to a vertical branch pipe, and the lower end of the vertical branch pipe is connected to the main pipeline.

[0007] A further technical solution is that the fluid channel is formed by fixing the two sides of the membrane cloth in the width direction to the inner wall of the air-supported membrane structure building, and the two ends of the membrane cloth in the length direction are gradually attached to and fixed to the inner wall of the air-supported membrane structure building.

[0008] A further technical solution is that the fluid channel is formed by fixing the two sides of the membrane cloth together in the width direction and then fixing the fluid channel to the inner wall of the air-supported membrane structure building.

[0009] A further technical solution is that the fluid channel is formed by fixing the first membrane fabric to the inner wall of the air-supported membrane structure building body, and then fixing the second membrane fabric to the first membrane fabric on both sides in the width direction.

[0010] A further technical solution is that the spray head includes a spray head and a core tube. A first flange is provided at one end of the core tube. An assembly hole is opened at the bottom of the fluid channel. The core tube passes through the assembly hole. The first flange is located inside the fluid channel. An external thread is provided on the core tube. A gasket and a nut are provided on the core tube. A water passage hole is provided in the middle of the core tube. The spray head is threadedly connected to the core tube. The water passage hole communicates with the spray head and the fluid channel.

[0011] (3) Due to the adoption of the above technical solution, the beneficial effects of this utility model are: a fluid channel formed by membrane cloth is set on the inner wall of the air-supported membrane structure building body, the membrane cloth is fixedly connected to the inner wall of the air-supported membrane structure building body, and multiple sprinkler heads are evenly distributed on the fluid channel. By using the membrane cloth as a fluid channel, that is, a fire pipe, it can better fit with the material, shape and other factors of the air-supported membrane structure building body. The membrane cloth is relatively lighter than traditional pipes. Moreover, the inner membrane and the membrane cloth of the air-supported membrane structure building body are connected by welding, which can achieve direct connection. Thus, fire pipes are set inside the air-supported membrane structure building body, which is more cost-effective than traditional methods.

[0012] The fluid channels include multiple channels, which are evenly distributed on the inner wall of the air-supported membrane structure building. The multiple fluid channels are connected to a main pipe, which is connected to a water supply device. The water supply device supplies water to the fluid channels, and the water is sprayed out from the sprinkler heads to achieve spraying. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0023] like Figures 1-9 As shown.

[0024] Example 1: An air-supported membrane structure building including a fire sprinkler system includes an air-supported membrane structure main body 1. Fluid channels 3 formed by membrane fabric 2 are provided on the inner wall of the air-supported membrane structure main body 1. The membrane fabric 2 is fixedly connected to the inner wall of the air-supported membrane structure main body 1. Multiple sprinkler heads 4 are evenly distributed on the fluid channels 3. The fluid channels 3 include multiple types, evenly distributed on the inner wall of the air-supported membrane structure main body 1. The multiple fluid channels 3 are connected to a main pipe 5, which is connected to a water supply device 6. The fluid channels 3 are formed by fixing the membrane fabric 2 to the inner wall of the air-supported membrane structure main body 1 on both sides in the width direction, and gradually pressing and fixing the membrane fabric 2 to the inner wall of the air-supported membrane structure main body 1 at both ends in the length direction. Vertical branch pipes 7 are connected to the ends of the fluid channels 3, and the lower ends of the vertical branch pipes 7 are connected to the main pipe 5. The spray head 4 includes a spray head 10 and a core tube 11. A first flange 12 is provided at one end of the core tube 11. An assembly hole 13 is opened at the bottom of the fluid channel 3. The core tube 11 passes through the assembly hole 13. The first flange 12 is located inside the fluid channel 3. An external thread is provided on the core tube 11. A gasket 14 and a nut 15 are provided on the core tube 11. A water passage hole is provided in the middle of the core tube 11. The spray head 10 is threadedly connected to the core tube 11. The water passage hole communicates with the spray head 10 and the fluid channel 3.

[0025] The main body 1 of an air-supported membrane structure generally includes three layers: an outer membrane, an inner membrane, and a heat insulation layer between the outer and inner membranes. In this embodiment, the membrane fabric 2 is welded and fixed to the outer membrane of the main body 1 of the air-supported membrane structure on both sides in the width direction (the welding between membranes is done using a membrane high-frequency welding machine, also called a membrane material welding machine). A fluid channel 3 is formed between the membrane fabric 2 and the inner membrane. The two ends of the membrane fabric 2 in the length direction are gradually attached to the inner membrane and welded and fixed to it. The fluid channel 3 is made simultaneously with the construction of the main body 1 of the air-supported membrane structure (after welding the fluid channel 3 to the inner membrane, the main body 1 of the air-supported membrane structure is then constructed using the inner membrane).

[0026] The sprinkler head 4 is an existing open fire sprinkler head 10 (fire sprinkler heads 10 are divided into open and closed types. Closed fire sprinkler heads 10 are normally closed and are activated by a thermal element at high temperatures. Open fire sprinkler heads 10 are normally closed and the nozzle is always open without a thermal element) with an added core 11 as a connector to allow it to connect to the membrane cloth 2. Before the membrane cloth 2 in the fluid channel 3 is connected to the inner membrane, the sprinkler head 4 is installed first. Specifically, mounting holes 13 are opened at equal intervals on the membrane cloth 2. The core 11 passes through the mounting holes 13 and two sealing rings are fitted on the core 11. The two sealing rings are located on both sides of the membrane cloth 2. The gasket 14 and nut 15 are installed. After tightening the nut 15, the edges of the mounting holes 13 are pressed between the first flange 12 and the gasket 14. The sealing rings can ensure the sealing performance. The reason why this utility model does not use a closed fire sprinkler head 10 is that the air-supported membrane structure building has an air intake and exhaust system inside, and the airflow is circulating. If a closed fire sprinkler head 10 is used, the temperature may not be reached and spraying will not be possible. Therefore, considering all factors, the direct control method is more suitable.

[0027] A second flange 16 is installed at the top of the vertical branch pipe 7. The second flange 16 is connected to the membrane cloth 2 through the connecting pipe 17. The connecting pipe 17 passes through the membrane cloth 2 (the membrane cloth 2 has a reserved hole). A first pressure plate 18 is installed at one end of the connecting pipe 17 located in the fluid channel 3. Two sealing rings are also fitted on the connecting pipe 17. The two sealing rings are located on both sides of the membrane cloth 2. The connecting pipe 17 is provided with external threads, and a second gasket 19 and a second nut 20 are provided on the connecting pipe 17. After the second nut 20 is tightened, it presses and seals the area around the reserved hole. A third flange 21 is installed at the end of the connecting pipe 17 that is connected to the vertical branch pipe 7. A sealing gasket is provided between the second flange 16 and the third flange 21, and the second flange 16 and the third flange 21 are fixedly connected by bolts.

[0028] The water supply device 6 can be directly supplied by fire hydrants. The main pipe 5 is connected to the fire hydrants. When sprinkler spraying is needed, the fire hydrants can be opened. Alternatively, a separate water tank can be installed, and water can be supplied to the main pipe 5 by a water pump. When sprinkler spraying is needed, the water pump can be turned on.

[0029] This utility model adopts the method of arranging the fluid channel 3 along the longitudinal (length direction) of the air-supported membrane structure building. In actual use, it can also be adjusted according to the shape of the air-supported membrane structure building.

[0030] Example 2: Based on Example 1, the difference is that the fluid channel 3 is formed by fixing the two sides of the membrane fabric 2 together in the width direction and then fixing the fluid channel 3 to the inner wall of the air-supported membrane structure 1. In this example, the membrane fabric 2 is formed into a tubular structure, and then the whole structure is welded and fixed to the inner membrane of the air-supported membrane structure 1. The fluid channel 3 formed by the membrane fabric 2 in this example is equivalent to a complete flexible tube, and the ends are welded and sealed.

[0031] Example 3: Based on Example 1, the difference is that the fluid channel 3 is formed by fixing the first membrane fabric 2 to the inner wall of the air-supported membrane structure 1, and then fixing the second membrane fabric 2 to both sides of the first membrane fabric 2 in the width direction. In this example, the two membrane fabrics 2 are first joined together to form a tubular structure, and then welded and fixed to the inner membrane of the air-supported membrane structure 1. The fluid channel 3 formed by the membrane fabric 2 in this example is also equivalent to a complete flexible tube, which can be sealed by welding at the end.

[0032] The above are merely preferred embodiments of this utility model.
