Description

Technical Field

[0001] This utility model relates to the field of air-supported membrane building technology, and in particular to an air-supported membrane building door structure and its installation structure. Background Technology

[0002] Air-supported membrane structures refer to building structures made of special architectural membrane materials, equipped with an intelligent electromechanical system that provides positive air pressure inside the membrane structure to support it. Due to their low cost, ease of assembly and disassembly, and lightweight nature, air-supported membrane structures are increasingly being used in various industries.

[0003] Because air-supported membrane structures are made entirely of air-supported membranes, their local support strength is limited. Existing doorways are too heavy to be directly installed on air-supported membrane structures. For example, the prior art patent (201610878869.5, titled "Air-supported Membrane Structure and its Door Structure") uses a separate door frame at the entrance of the air-supported membrane structure. This door frame is fixedly connected to the ground and sealed to the entrance / exit of the air-supported membrane structure. A door is then installed inside the door frame to allow entry and exit. While this door structure is stable and durable, it is complex, costly, and inconvenient to install. It is also unsuitable for large doors such as those for large vehicles or industrial trucks, and cannot be moved with the air-supported membrane structure when it needs to be moved. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an air-supported membrane building door structure and its installation structure that is simple in structure, lightweight, and easy to install and disassemble.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: An air-supported membrane building door structure includes a truss structure door frame and an airbag door body. The truss structure door frame has an internal cavity for accommodating the airbag door body. The airbag door body is disposed in the cavity. The outer wall of the airbag door body abuts against the inner wall of the truss structure door frame. The truss structure door frame limits the movement of each side of the airbag door body. Multiple wheels are fixedly provided at the bottom of the truss structure door frame. A number of pin locks are provided at the lower part of one side of the truss structure door frame. A hook structure is provided at the upper part of the side of the truss structure door frame with the pin locks.

[0006] The beneficial effects of this utility model are as follows: This utility model uses a truss structure door frame to support the airbag door body, which greatly reduces the weight of the door structure; because the truss structure door frame can limit and support each side of the airbag door body, it ensures the stability of the airbag door body installation and the strength of the entire door structure; by inserting a bolt lock into the bottom surface of the installation position of the door structure, and then connecting the upper part of the door structure through a hook structure, it is convenient to install and disassemble the door structure at the door installation opening, and also convenient to open and close the door structure.

[0007] Meanwhile, because this utility model adopts a truss structure door frame and airbag door body door structure, it can be easily opened and closed in extreme wind conditions and continuous wind conditions. The structure is stable, the cost is low, and there is no need to use steel structure to fix it to the ground. The size can be made to meet the needs of large vehicles and industrial trucks to enter and exit.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

The internal spaces of the circumferential frame, the transverse frame and the longitudinal frame are connected to form a receiving cavity for accommodating the airbag door body. The circumferential frame, the transverse frame and the longitudinal frame support and limit the various surfaces of the airbag door body from different directions, thereby improving the overall strength and rigidity of the door structure.

[0011] Furthermore, the number of circumferential frames, the number of transverse frames, and the number of longitudinal frames are all two or more. The two or more circumferential frames are evenly spaced along the thickness direction of the airbag door, the two or more transverse frames are evenly spaced along the length direction of the airbag door, and the two or more longitudinal frames are evenly spaced along the width direction of the airbag door.

[0012] The beneficial effect of adopting the above-mentioned further scheme is that the number of circumferential frames, transverse frames and longitudinal frames are all two or more, which further improves the strength of the truss structure door frame, thereby improving the strength of the door structure.

[0013] Furthermore, it also includes multiple diagonal braces, which are respectively located on the outer sides of both sides of the airbag door body, and the two ends of the diagonal braces are respectively fixedly connected to the transverse frame and / or the longitudinal frame.

[0014] The beneficial effects of adopting the above-mentioned further solution are: the diagonal tie rods are set on the outer sides of both sides of the airbag door body, and the two ends are fixedly connected to the horizontal frame and / or the longitudinal frame, which can further improve the connection strength between the horizontal frame and / or the longitudinal frame, improve the strength of the truss structure door frame, and thus improve the strength of the door structure.

[0015] Furthermore, the truss structure door frame has a bolt fixing structure in the middle of the side where the bolt lock is located, for inserting the bolt.

[0016] The beneficial effect of adopting the above-mentioned further solution is that the bolt setting enables the two door structures to be connected to the bolt fixing structure on both door structures simultaneously through the bolt when the door installation opening is closed using two door structures, thereby achieving the locking of the two door structures.

[0017] Furthermore, a rubber sealing strip is fixedly provided at the bottom of the truss structure door frame.

[0018] The beneficial effect of adopting the above-mentioned further solution is that the rubber sealing strip can block the wind.

[0019] Furthermore, the airbag door is provided with an air inlet, which is connected to one end of a retractable hose, and the other end of the retractable hose is connected to the output end of the air replenishment device.

[0020] The beneficial effects of adopting the above-mentioned further solution are: the installation of the retractable hose makes it convenient to inflate the airbag door, and due to the elasticity of the retractable hose, it will not affect the opening and closing process of the door structure.

[0021] This utility model, in order to solve the above-mentioned technical problems, also provides an air-supported membrane building door structure installation structure, including a door installation opening provided on the air-supported membrane building and the aforementioned air-supported membrane building door structure.

[0036] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0037] Example 1

[0038] like Figures 1 to 4 As shown, this embodiment discloses an air-supported membrane building door structure, including a truss structure door frame 1 and an airbag door body 2. The truss structure door frame 1 has an internal cavity for accommodating the airbag door body 2. The airbag door body 2 is disposed in the cavity, and the outer wall of the airbag door body 2 abuts against the inner wall of the truss structure door frame 1. The truss structure door frame 1 limits the movement of each side of the airbag door body 2. The bottom of the truss structure door frame 1 is fixedly provided with multiple traveling wheels 3. The traveling wheels 3 are universal wheels, preferably polyurethane universal wheels, which are installed without jamming to ensure smooth opening and closing of the door structure and improve the convenience of door structure movement. The lower part of one side of the truss structure door frame 1 is provided with a number of latch locks 4. The number of latch locks 4 is preferably two, and the two latch locks 4 are spaced apart on the lower part of one side of the truss structure door frame 1. The upper part of the side of the truss structure door frame 1 with the latch locks 4 is provided with a hook structure 5.

[0039] In this embodiment, the truss structure door frame 1 includes a circumferential frame 101, a transverse frame 102, and a longitudinal frame 103. The circumferential frame 101 extends circumferentially along the airbag door body 2, the transverse frame 102 extends transversely along the airbag door body 2, and the longitudinal frame 103 extends longitudinally along the airbag door body 2. Both ends of the transverse frame 102 are fixedly connected to the circumferential frame 101, and both ends of the longitudinal frame 103 are fixedly connected to the circumferential frame 101, such that the circumferential frame 101, the transverse frame 102, and the longitudinal frame 103 constitute a spatial truss structure. The interiors of the circumferential frame 101, the transverse frame 102, and the longitudinal frame 103 are interconnected to form the... The airbag door 2 is located inside the circumferential frame 101, the transverse frame 102, and the longitudinal frame 103. The outer wall of the airbag door 2 abuts against the inner wall of the circumferential frame 101, the inner wall of the transverse frame 102, and the inner wall of the longitudinal frame 103. The truss structure door frame 1 includes the circumferential frame 101, the transverse frame 102, and the longitudinal frame 103. The internal spaces of the circumferential frame 101, the transverse frame 102, and the longitudinal frame 103 are connected to form an accommodating cavity for accommodating the airbag door 2. The circumferential frame 101, the transverse frame 102, and the longitudinal frame 103 support and limit the various surfaces of the airbag door 2 from different directions, thereby improving the overall strength and rigidity of the door structure.

[0040] Preferably, the number of circumferential frames 101, the number of transverse frames 102, and the number of longitudinal frames 103 are all two or more. The two or more circumferential frames 101 are evenly spaced along the thickness direction of the airbag door body 2, the two or more transverse frames 102 are evenly spaced along the length direction of the airbag door body 2, and the two or more longitudinal frames 103 are evenly spaced along the width direction of the airbag door body 2. Using two or more of each of the circumferential frame 101, transverse frame 102, and longitudinal frame 103 further improves the strength of the truss structure door frame 1, thereby increasing the strength of the door structure.

[0041] Furthermore, the system also includes multiple diagonal braces 104, which are respectively disposed on the outer sides of both sides of the airbag door body 2. Preferably, at least two diagonal braces 104 are disposed on each side of the airbag door body 2, and the two diagonal braces 104 are arranged crosswise. The two ends of each diagonal brace 104 are fixedly connected to the transverse frame 102 and / or the longitudinal frame 103, respectively. The diagonal braces 104 are disposed on the outer sides of both sides of the airbag door body 2, and their two ends are fixedly connected to the transverse frame 102 and / or the longitudinal frame 103, which can further improve the connection strength between the transverse frame 102 and / or the longitudinal frame 103, improve the strength of the truss structure door frame 1, and thus improve the strength of the door structure.

[0042] In this embodiment, the truss structure door frame 1 is preferably made of wood or a lightweight metal such as aluminum alloy, with wood being the preferred material. In a preferred embodiment of this utility model, the circumferential frame 101, the transverse frame 102, and the longitudinal frame 103 are all made of bent square wooden strips, with the two ends of the square wooden strips fixedly connected to form a frame structure. Specifically, conventional fixing methods in the prior art, such as screw fixing, riveting, or mortise and tenon fixing, can be used for the fixed connection.

[0043] Preferably, the bends of the circumferential frame 101, the transverse frame 102, and the longitudinal frame 103 are made of arc-shaped transitions, forming a frame structure with arc-shaped transitions. This makes the structure of the circumferential frame 101, the transverse frame 102, and the longitudinal frame 103 more aesthetically pleasing, and thus makes the structure of the truss structure door frame 1 more aesthetically pleasing. At the same time, since the bends of the circumferential frame 101, the transverse frame 102, and the longitudinal frame 103 are made of arc-shaped transitions, the adjacent two surfaces of the airbag door body 2 are made of circular structures corresponding to the bends of the circumferential frame 101, the transverse frame 102, and the longitudinal frame 103. This makes the contact between the airbag door body 2 and the inner walls of the circumferential frame 101, the transverse frame 102, and the longitudinal frame 103 more tightly fitted, improving the sealing performance of the contact between the airbag door body 2 and the circumferential frame 101, the transverse frame 102, and the longitudinal frame 103.

[0044] After the circumferential frame 101, the transverse frame 102 and the longitudinal frame 103 are manufactured, they need to be polished to improve their smoothness and avoid damage to the airbag body and the air-supported structure 11.

[0045] In this embodiment, the hook structure 5 includes a steel plate 501 and an L-shaped steel column 502. The steel plate 501 is provided with a plurality of fixing holes evenly distributed, so that the steel plate 501 can be fixed to the truss structure door frame 1 by high-strength self-tapping screws. Specifically, the steel plate 501 is fixed to the horizontal frame 102 or the vertical frame 103. One end of the L-shaped steel column 502 is welded and fixedly connected to one side of the steel plate 501, and the other end of the L-shaped steel column 502 is set downward.

[0046] In this embodiment, the truss structure door frame 1 has a bolt fixing structure 6 for inserting a bolt 7 in the middle of the side where the bolt lock 4 is located. The bolt fixing structure 6 includes a fixing seat with a hole for inserting the bolt 7. The bolt 7 enables the two door structures to be connected to the bolt fixing structure 6 on both door structures simultaneously when the door mounting opening 12 is closed using two door structures, thereby achieving the locking of the two door structures.

[0047] In this embodiment, a rubber sealing strip 8 is fixedly provided at the bottom of the truss structure door frame 1, and the rubber sealing strip 8 can play a role in blocking the wind.

[0048] The airbag door 2 is provided with an air inlet 9, which is connected to one end of a retractable hose 10. The other end of the retractable hose 10 is connected to the output end of an air replenishment device. The retractable hose 10 facilitates the inflation of the airbag door 2. The airbag door 2 can be kept inflated by sealing the air inlet 9 with a plug, or by using an air replenishment device to keep the air inlet 9 inflated. A pressure sensor ensures that the air pressure inside the airbag door 2 is stable. At the same time, due to the elasticity of the retractable hose 10, it will not affect the opening and closing process of the door structure.

[0049] In this embodiment, the present invention uses a truss-structured door frame 1 to support the airbag door body 2, greatly reducing the weight of the door structure. Because the truss-structured door frame 1 can provide limiting support to each surface of the airbag door body 2, it ensures the stability of the airbag door body 2 installation and the strength of the entire door structure. A bolt lock 4 is inserted into the bottom surface of the door structure at the installation position, and then a hook structure 5 connects to the upper part of the door structure, facilitating the installation and disassembly of the door structure at the door mounting opening 12, and also facilitating the opening and closing of the door structure. Because the present invention uses a truss-structured door frame 1 and an airbag door body 2, it can be easily opened and closed in extreme and continuous high wind environments, has a stable structure, low cost, does not require a steel structure fixed to the ground, and can be customized to meet the needs of large vehicles and industrial trucks.

[0050] Example 2

[0051] like Figures 5 to 7As shown, this embodiment discloses an air-supported membrane building door structure installation structure, including a door mounting opening 12 provided on the air-supported membrane building 11 and the aforementioned air-supported membrane building door structure. The truss structure door frame 1 is located inside the door mounting opening 12. A hanging rope 1301 mechanism 13 is fixedly provided at the top of the door mounting opening 12. The hanging rope 1301 mechanism 13 is connected to the hook structure 5. The bottom of the door mounting opening 12 is provided with a pin hole 14 corresponding to the pin lock 4. The pin hole 14 is drilled after the door structure is installed on site to ensure that the pin hole 14 and the pin lock 4 are accurately aligned. A stainless steel edge ring is attached to the edge of the pin hole 14 to ensure that the edge of the pin hole 14 is not easily damaged during use. The pin lock 4 is inserted into the pin hole 14. The door structure is connected to the bottom surface of the door mounting opening 12 by means of a bolt lock 4, and then the upper part of the door structure is connected to the top of the door mounting opening 12 by means of a hanging rope 1301 mechanism 13 and a hook structure 5, thereby realizing the installation of the door structure at the door mounting opening 12. The bolt lock 4 and the hanging rope 1301 mechanism 13 are easy to open and close, realizing the quick opening and closing of the door structure.

[0052] In this embodiment, there are two door structures at the door mounting opening 12, and the two door structures are arranged side by side, so that a double door is formed at the door mounting opening 12.

[0053] In this embodiment, the inner walls on both sides of the door mounting opening 12 are provided with side additional membranes 15 extending into the door mounting opening 12, and the top of the door mounting opening 12 is provided with a top additional membrane 16 extending into the door mounting opening 12. The side additional membranes 15 and the top additional membrane 16 abut against one side of the truss structure door frame 1. The side additional membranes 15 and the top additional membrane 16 can seal the sides and top of the door structure.

[0054] The two side-attached membranes 15 are respectively fixed on the two side walls of the door mounting opening 12. After the side-attached membranes 15 are set, the two door structures can be fixedly connected to the side-attached membranes on their opposite sides. Specifically, they can be fixedly connected by aluminum plates or by columns fixedly connected to the door structures so that the door structures are fixedly connected to the side-attached membranes 15. At this time, the side-attached membranes 15 can not only block the wind, but also serve as the rotation axis for the door structures to rotate. After the bolt locks 4 of the two door structures are disengaged from the bolt holes 14 and the hook structures 5 are disengaged from the hanging ropes 1301, the door mounting opening 12 can be opened by rotating around the side-attached membranes 15 as the rotation axis.

[0055] In this embodiment, the hanging rope 1301 mechanism 13 includes a hanging rope 1301 and a hanging rope fixing member 1302. The hanging rope 1301 is fixed to the top of the door mounting opening 12 by the hanging rope fixing member 1302. The hanging rope fixing member 1302 can be made of rubber plate or other material. Both ends of the hanging rope 1301 are fixedly connected to the rubber plate or other material. The hanging rope fixing member 1302 can be glued to the air-supported membrane structure 11 or fixed to the air-supported membrane structure 11 by using a common fixing method in the prior art. The middle part of the hanging rope 1301 forms a hanging opening for hanging on the L-shaped steel column 502 of the hook structure 5. The hanging rope 1301 mechanism 13 uses a hanging rope 1301 and a hanging rope fixing member 1302, which has a simple structure and is convenient for connection and disassembly with the hook structure 5.

[0056] In the embodiments of this utility model, in addition to using the hanging rope 1301 and the hook structure 5 for hooking, the hanging rope 1301 mechanism 13 can also use other hooking structures, such as using a rigid connecting plate. One end of the connecting plate is hinged to the hanging rope 1301 fixing frame, and the other end of the connecting plate is provided with a hook opening. By rotating the connecting plate, the hook opening can be rotated to the hooking structure.

[0057] Because the air-supported membrane gate will deform after inflation, the hook structure 5 should be installed after the gate structure is installed in the door mounting opening 12, so as to ensure that the position of the hanging rope 1301 mechanism 13 and the hook structure 5 can be accurately connected.

[0058] In this embodiment, the airbag door 2 is installed after the truss structure door frame 1 is installed at the door mounting opening 12, and the shape of the inflated airbag perfectly fits inside the truss structure door frame 1.

[0059] Closing and opening the door structure: After the door structure is installed, push the two door structures to close the two doors in place. First, insert the door bolt fixing structure 6 in the middle of the two door structures with the wooden door bolt 7. Then, insert the bolt lock 4 at the bottom of the door structure into the bolt hole 14 in the ground. Finally, use the extended hook rod with hook to pull down the hanging rope 1301 and hook it onto the hook structure 5. This completes the fixing of the door structure. The reverse is the opening method.

[0060] The truss structure door frame 1 of this utility model adopts a wooden structure and adopts two door structures to achieve double opening. The interior of the truss structure door frame 1 is filled with an airbag door body 2 made of membrane material. The door structure is fixed in all directions by the cooperation of the bolt lock 4 with the bolt hole 14, the cooperation of the hanging rope 1301 mechanism 13 with the hook structure 5, and the cooperation of the bolt 7 with the bolt fixing structure 6 on the two door structures, so that the installation of the door structure is solid and reliable.

[0061] This utility model abandons traditional steel materials and uses wood instead, significantly reducing material costs and making the door structure lightweight, which better matches the theme of lightness and flexibility of the air-supported membrane structure 11, while ensuring strength and flexible opening and closing. When the air-supported membrane structure 11 needs to be moved to a different location, the door structure can also be moved accordingly, which is impossible with traditional steel structure doors.

[0062] In existing technologies, most entrance doors use steel structures as frames and are made with steel doors or steel-framed glass doors. Using wood instead would greatly reduce costs.

[0063] Traditional entrance doors are made entirely of steel structures. With the same amount of steel used, the door structure of this utility model is significantly lighter, and the lighter weight makes it easier to open and close manually.

[0064] Since the installation method involves connecting the side-attached membrane 15 to the door structure, no changes are needed to the door structure. Only the dimensions of the door structure are required to complete the design, thus achieving standardization.
