Description

Technical Field

[0001] This utility model belongs to the field of air-supported membrane architecture, and in particular relates to an air-supported membrane structure building that includes a telescopic entrance and exit passage. Background Technology

[0002] Currently, air-supported membrane structures are used for purposes such as stadiums, exhibition halls, and warehouses. For warehouse-type air-supported membrane structures, they are generally equipped with pedestrian walkways and vehicle and equipment access routes. Pedestrian walkways typically have revolving doors at the entrance of the air-supported membrane structure, while vehicle access routes usually use roller shutter doors. Single-door air-supported membrane structures can cause excessive pressure loss when vehicles enter or exit, requiring high-powered fans to supply air. Later, in order to reduce the pressure loss of the air-supported membrane structure when vehicles enter or exit, a double roller shutter door system was adopted. The two roller shutter doors are sealed with a concrete structure to form a passage. When vehicles enter or exit, the outer door is opened first, the vehicle drives into the passage, the outer door is closed, the inner door is opened, and the vehicle drives into the air-supported membrane structure. This can reduce the pressure loss of the air-supported membrane structure. However, this type of passage is only used during vehicle entry and exit periods. For places with limited space, this type of passage permanently occupies the space, resulting in wasted space and increased costs. Utility Model Content

[0003] (1) Technical problem to be solved: an air-supported membrane structure building with telescopic entrance and exit passage.

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

[0005] An air-supported membrane structure building including a retractable entrance / exit passage is disclosed. The main body of the air-supported membrane structure building has an entrance / exit on its side. An inner door is fixedly installed at the entrance / exit. One side of the inner door frame is fixedly connected to and sealed to the main body of the building. The other side of the inner door frame is connected to the retractable entrance / exit passage. The retractable entrance / exit passage includes a retractable passage frame and a membrane fabric. One end of the retractable passage frame is fixedly connected to the inner door frame, and the other end of the retractable passage frame is connected to the outer door frame. The membrane fabric covers the retractable passage frame and is connected to the retractable passage frame. Tracks are provided on both sides of the lower part of the retractable passage frame. The retractable passage frame and the outer door frame are movably mounted on the tracks. A sealing device is provided between the membrane fabric and the tracks or the ground.

[0006] A further technical solution is that the telescopic passage frame includes a portal frame, and there are multiple portal frames. Adjacent portal frames are connected by a scissor telescopic mechanism. The scissor telescopic mechanism includes a first connecting arm and a second connecting arm. The first connecting arm and the second connecting arm cross and are connected to the portal frame by a pin. Each portal frame corresponds to at least two scissor telescopic mechanisms. Between adjacent portal frames, the first connecting arm corresponding to one portal frame is hinged to the second connecting arm corresponding to another portal frame by a pin, and the second connecting arm corresponding to one portal frame is hinged to the first connecting arm corresponding to another portal frame by a pin. The portal frame closer to the inner door is fixed to the inner door frame, and the portal frame closer to the outer door is fixed to the outer door frame.

[0007] A further technical solution is that the track is provided with a U-shaped groove, and pulley assemblies are provided at the bottom of the portal frame of the telescopic channel frame and at the bottom of the door frame of the outer door, with the pulley assemblies located inside the groove.

[0008] A further technical solution is that sealing grooves are provided on the outer sides of both tracks, second extension plates are provided on both sides of the bottom of the door-shaped bracket, and third extension plates are provided on both sides of the bottom of the door frame of the outer door. The lower ends of the second and third extension plates are located inside the corresponding sealing grooves. A first sealing brush is provided on the inner wall of the sealing groove. The two transverse ends of the membrane cloth are fixed to the second and third extension plates at the corresponding positions, and the membrane cloth is in contact with the first sealing brush.

[0009] A further technical solution is to provide a second sealing brush at the bottom of the door frame of the outer door.

[0010] (3) Due to the adoption of the above technical solution, the beneficial effects of this utility model are as follows: by fixing an inner door at the entrance and exit, the other side of the inner door frame is connected to a telescopic entrance and exit channel, wherein one end of the telescopic channel frame is fixedly connected to the inner door frame, and the other end of the telescopic channel frame is connected to the outer door frame, the membrane is covered on the telescopic channel frame, and the membrane is connected to the telescopic channel frame. The telescopic entrance and exit channel is realized by utilizing the movable outer door, the telescopicity of the telescopic channel frame, and the flexibility of the membrane. When the outer door moves towards the inner door, the telescopic channel frame contracts to shorten its length. This state is used when there is no need for vehicles to enter or exit the air-supported membrane building. When the outer door moves away from the inner door, the telescopic channel frame extends to lengthen its length. This state is used when vehicles need to enter or exit the air-supported membrane building. It can be used flexibly according to the actual situation to avoid occupying the site for a long time.

[0011] Tracks are installed on both sides of the lower part of the telescopic passage frame. Both the telescopic passage frame and the door frame of the outer door are movably mounted on the tracks, which facilitates the movement of the outer door to extend or retract the telescopic passage frame. A sealing device is installed between the membrane and the track or the ground to facilitate sealing of the bottom of the membrane and reduce air leakage. Attached Figure Description

[0028] 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.

[0029] like Figures 1-16 As shown.

[0030] Example 1: An air-supported membrane structure building including a telescopic entrance / exit passage. The main body 1 of the air-supported membrane structure building has an entrance / exit 2 on its side. An inner door 3 is fixedly installed at the entrance / exit 2. One side of the door frame of the inner door 3 is fixedly connected to and sealed to the main body of the building. The other side of the door frame of the inner door 3 is connected to the telescopic entrance / exit passage. The telescopic entrance / exit passage includes a telescopic passage frame 4 and a membrane 5. One end of the telescopic passage frame 4 is fixedly connected to the door frame of the inner door 3. The other end of the telescopic passage frame 4 is connected to the door frame of the outer door 20. The membrane 5 is covered on the telescopic passage frame 4 and connected to the telescopic passage frame 4. Tracks 6 are provided on both sides below the telescopic passage frame 4. The telescopic passage frame 4 and the door frame of the outer door 20 are movably mounted on the tracks 6.

[0031] In use, both the inner door 3 and the outer door 20 are roller shutter doors. The door frame of the inner door 3 is fixedly connected to the main body 1 of the air-supported membrane structure. At the same time, the bottom of the door frame of the inner door 3 is fixed to the ground by anchor bolts. In the existing technology, the membrane and the frame are generally connected by a pressure plate 19 and bolts to fix the membrane to the frame. The roller shutter door used in air-supported membrane structures has a sealing brush between the roller shutter and the door frame, and there is also a sealing gasket or sealing brush at the bottom of the roller shutter (these are also used in traditional air-supported membrane structures. The main improvement of this utility model is in the telescopicity of the passage). The telescopic passage frame 4 includes a gate-shaped support 7, and there are multiple gate-shaped supports 7. Adjacent gate-shaped supports 7 are connected by a scissor telescopic mechanism. The scissor telescopic mechanism includes a first connecting arm 8 and a second connecting arm 9. Two connecting arms 9, the first connecting arm 8 and the second connecting arm 9 cross and are connected to the gate-shaped bracket 7 by a pin 10. Each gate-shaped bracket 7 corresponds to at least two scissor telescopic mechanisms. Between adjacent gate-shaped brackets 7, the first connecting arm 8 corresponding to one gate-shaped bracket 7 and the second connecting arm 9 corresponding to another gate-shaped bracket 7 are hinged by a pin 21, and the second connecting arm 9 corresponding to one gate-shaped bracket 7 and the first connecting arm 8 corresponding to another gate-shaped bracket 7 are hinged by a pin 22. The gate-shaped bracket near the inner door 3 is fixed to the door frame of the inner door 3, and the gate-shaped bracket near the outer door 20 is fixed to the door frame of the outer door 20 (the length of the first connecting arm 8 and the second connecting arm 9 on the gate-shaped brackets at both ends of the telescopic passage frame 4 is only half. When the telescopic passage frame 4 is in the extended state, the membrane fabric 5 and the gate-shaped support are connected to the bolts via pressure plates 19. Both ends of the membrane fabric 5 hang down in the width direction, contacting the ground with some allowance. In the extended state, pressing heavy objects onto both ends of the membrane fabric 5 to make it adhere to the ground can also reduce air leakage. Because the air-supported membrane structure relies on real-time inflation and pressurization to achieve its shape, and also has exhaust ports, it maintains internal pressure balance while achieving ventilation. Therefore, the air leakage of the membrane fabric 5, outer door 20, and inner door 3 can be offset by increasing the air intake. The telescopic passage frame 4 and the door frame of the outer door 20 can be connected to the track 6 using sliders or pulleys. The two ends of the membrane fabric 5 in the longitudinal direction (telescopic direction) are fixed to the door frames of the outer door 20 and inner door 3, respectively. The membrane fabric 5 and the door frames are also connected to the track 6 via pressure plates 19 and bolts. The track 6 and the sealing groove 13 can be made into an integrated structure.

[0032] Example 2:

[0033] Based on the embodiment, the track 6 is provided with a U-shaped groove 11. Pulley assemblies 12 are provided at the bottom of the portal frame 7 of the telescopic channel frame 4 and at the bottom of the door frame of the outer door 20. The pulley assembly 12 is located inside the groove 11 and includes a T-shaped wheel frame 23. Bearings 24 are connected to both sides of the lower part of the wheel frame 23 via shafts. The bearings 24 contact the bottom of the groove 11. The upper part of the wheel frame 23 is bolted to the bottom of the corresponding portal frame 7 or the bottom of the door frame of the outer door 20. A cover plate is fixedly installed on the upper part of the track 6, with a slot in the middle. The wheel frame 23 passes through the slot. The cover plate is used to restrict the bearings 24, which act as wheels, to prevent them from detaching from the track 6. The upper surface of the track 6 is flush with the ground (concrete).

[0034] A sealing device is provided between the membrane fabric 5 and the track 6 or the ground. The sealing device includes a sealing groove 13 on the outer side of both tracks 6, with the top of the sealing groove 13 flush with the top of the track 6. A second extension plate 15 is provided on both sides of the bottom of the door-shaped bracket 7, and a third extension plate 16 is provided on both sides of the bottom of the door frame of the outer door 20. The lower ends of the second extension plate 15 and the third extension plate 16 are located inside the corresponding sealing groove 13. A first sealing brush 17 is provided on the inner wall of the sealing groove 13. The two transverse ends of the membrane fabric 5 are fixed to the second extension plate 15 and the third extension plate 16 at the corresponding positions, and the membrane fabric 5 is in contact with the first sealing brush 17. The second extension plate 15 and the third extension plate 16 are used to position the two ends of the membrane cloth 5 in the sealing groove 13, so that the ends of the membrane cloth 5 can move with the second extension plate 15 and the third extension plate 16 inside the sealing groove 13. The first sealing brush 17 can make the membrane cloth 5 better sealed to the ground and reduce the amount of air leakage. Since the inner door 3 is fixed, the membrane cloth 5 at the inner door 3 can be directly fixed to the door frame of the inner door 3 and the ground (the fixing method is also the same as the method of using pressure plate 19 and bolts).

[0035] A second sealing brush 18 is installed at the bottom of the door frame of the outer door 20 to improve the sealing between the outer door 20 and the ground and track 6, which can further reduce the amount of air leakage.

[0036] The portal frame 7 in this utility model can also be used as... Figure 16 The telescopic scissor telescopic structure in the present invention has a sliding groove, which is different from that in embodiment 1, the sliding groove is not required.

[0037] The first sealing brush 17 and the second sealing brush 18 in this utility model are both existing technologies that utilize dense bristles to block airflow exchange.

[0038] The above are merely preferred embodiments of this utility model.
