Description

Technical Field

[0001] The invention relates to the field of air film buildings, and in particular to a modular detachable air film facility and a construction method. Background Art

[0002] Air-supported buildings have been widely used in many fields due to their unique advantages, such as fast construction speed, flexible space utilization, energy saving and environmental protection. However, traditional air-supported buildings have obvious limitations when facing different scales and functional requirements. Most existing air-supported buildings are integral structures, and their scale and function are determined during the initial design and construction, making it difficult to effectively adjust and change them during subsequent use. When project requirements change, such as the need to expand or reduce the scale of the building, increase or change functional zoning, traditional air-supported buildings often require large-scale transformation or even reconstruction, which not only consumes a lot of manpower, material resources and time costs, but is also difficult to achieve in many cases due to site restrictions or complex construction conditions.

[0003] A Chinese patent (publication number CN 116180899 B, publication date 2023.05.30) discloses a closed inflatable membrane structure, including an air membrane main body, a fan assembly, a vehicle entry device, and a human entry device. The air membrane main body is connected to the fan assembly, the air membrane main body is connected to the vehicle entry device, the fan assembly is connected to the vehicle entry device, and the air membrane main body is connected to the human entry device. The eccentric shaft on the clamp is clamped in the pin notch, and one end of the clamp is pressed downward to fix the middle air membrane and the edge air membrane. This method is firm and fast, and it is convenient to disassemble the entire air membrane structure from the ground structure. The adjacent middle air membranes and the middle air membranes and the edge air membranes are respectively connected and installed by connecting pieces by thermoplastic connection. The use of thermoplastic connection is still not convenient for adjustment and change of air membrane buildings, and it is difficult to adapt to the needs of adjusting the scale and form of buildings. In addition, the connection methods of traditional air-supported buildings are usually more complicated. For example, the above-mentioned thermoplastic connection method requires professional construction personnel to use specific tools for installation and disassembly operations, which limits the promotion and application of air-supported buildings. Especially in some scenarios with high requirements for construction efficiency and relatively simple construction conditions, the disadvantages of traditional connection methods are more prominent, affecting construction efficiency and stability after construction. Summary of the invention

[0004] The purpose of the present invention is to provide a modular detachable air-film facility and a construction method in view of the defects of the prior art. The modular connection design of the magnetic card slot combined with the elastic pad solves the core pain points of the traditional air-film building connection method, such as rigid connection, complex construction and poor reusability, and achieves a technological breakthrough of rapid disassembly and assembly, high sealing and low-cost reuse. It is particularly suitable for scenarios that require flexible adjustment of scale, rapid deployment or limited construction conditions (such as post-disaster reconstruction, temporary warehousing, mobile exhibition halls), and promotes the development of air-film buildings towards lighter, smarter and more sustainable directions.

[0005] The first object of the present invention is to provide a modular detachable air membrane facility, which adopts the following scheme:

[0006] It includes multiple air film modules that are spliced ​​together, and a functional cavity is formed inside the spliced ​​air film modules. Connectors are installed at the corresponding splicing positions of the air film modules. The connectors include card slots and card blocks distributed along the splicing seams. A recess for accommodating the card block is formed in the card slot. An elastic pad is provided on the inner wall of the recess. The elastic pad is configured to fit the portion of the card block that probes into the card slot. The card block is provided with a flexible magnet and is configured to be detachably connected to the card slot, and the flexible magnet is adsorbed on the card slot.

[0007] Furthermore, the card slot forms an opening toward one side of the matching card block, the inner walls of the recess on both sides of the opening are provided with serrated protrusions, the card block is provided with serrated grooves adapted to the serrated protrusions, and the serrated protrusions and the serrated grooves are configured to be engaged with each other.

[0008] Furthermore, the elastic pad is arranged between the sawtooth protrusion and the sawtooth groove, and deforms along with the sawtooth protrusion and the sawtooth groove, and the elastic pad is connected to the card slot.

[0009] Furthermore, the air film module includes an end module and a basic module, the basic module is arched, and multiple basic modules are spliced ​​in sequence through connectors, and the end module is partially spherical shell-shaped, and the end module is spliced ​​at both ends of multiple basic modules.

[0010] Furthermore, the basic module is provided with a light-transmitting hole and a light-transmitting film is installed to serve as a lighting module, and some lighting modules are provided with ventilation holes and a fan is installed to serve as a ventilation and lighting module.

[0011] Furthermore, a first entrance and exit is set on the basic module and a door assembly is installed as a personnel entrance and exit module. The door assembly includes a door, an air pressure sensor, a hydraulic rod and a controller. The door is installed on the basic module through a door frame. The air pressure sensor measures the air pressure near the door assembly and sends it to the controller. One end of the hydraulic rod is connected to the door frame and the other end is connected to the door. The hydraulic rod is connected to the controller, and the controller is used to control the movement of the hydraulic rod.

[0012] Furthermore, a control room and a second inlet and outlet are arranged on the terminal module as a vehicle inlet and outlet module.

[0013] Furthermore, the air film module body is an air film body, which includes an air film outer layer, an air film interlayer and an air film inner layer distributed in sequence, and the air film interlayer is filled in a cavity formed by the air film outer layer and the air film inner layer.

[0014] Furthermore, one side of the air membrane module is connected to a card slot, and the other side is connected to a card block.

[0015] The second object of the present invention is to provide a construction method of a modular detachable air membrane facility as described in the first object, comprising:

[0016] Arrange multiple air film modules, and connect adjacent air film modules through the card slots and card blocks of the connectors, so that a seam is formed at the connection position, and a functional cavity is formed inside the air film module;

[0017] During expansion, the joints at the set positions are removed, the air film modules on at least one side of the joints are moved, and new air film modules are installed to establish connections with other air film modules;

[0018] When shrinking the building, the joints at the set positions are removed, some air film modules are removed, the positions of other air film modules are adjusted, and the connections between the remaining air film modules are re-established.

[0019] Furthermore, the seam position clamping block is clamped with the clamping groove, and the seam position is sealed under the action of the internal pressure of the functional cavity and the elastic pad.

[0020] Compared with the prior art, the present invention has the following advantages and positive effects:

[0021] In view of the problem that it is difficult to disassemble the modules of the current air membrane structure, which makes it difficult to adjust the scale or shape of the building, the adsorption effect of flexible magnets and card slots can be used to achieve rapid alignment and detachable connection of adjacent modules. No professional tools or high-temperature welding are required, and physical damage to the membrane material by traditional mechanical clamping is avoided, which significantly lowers the construction threshold. The elastic pad on the inner wall of the recess fits the card block and adapts to module deformation and air pressure fluctuations to avoid sealing failure due to installation errors or material expansion and contraction, thereby ensuring airtightness. Flexible magnet adsorption provides initial airtightness, and elastic pads further fill the gaps to form a redundant sealing layer to reduce the risk of air leakage (especially to adapt to changes in wind pressure or extreme climates). Modules can be flexibly increased or decreased or rearranged to adapt to temporary activities, emergency rescue and other scenarios that require rapid adjustment of scale.

[0022] In addition, the combination of elastic pads and flexible magnets can buffer the deformation of the membrane material caused by temperature changes or uneven loads, maintain the long-term stability of the joints, and eliminate the need for heavy metal components in the connectors, reducing the overall weight. It is suitable for sites with poor geological conditions, simplifies the construction process, and reduces dependence on professionals. The modules are reusable, reducing material waste.

[0023] The card slot forms an opening toward one side of the matching card block, and the inner walls of the recessed portion on both sides of the opening are provided with serrated protrusions, and the card block is provided with serrated grooves adapted to the serrated protrusions. The two are connected with each other, which greatly enhances the stability and firmness of the connection between the card slot and the card block. The elastic pad is arranged between the serrated protrusion and the serrated groove, follows their deformation, and is connected to the card slot, which can not only reduce friction loss, but also provide buffering, thereby improving the reliability and service life of the connection.

DETAILED DESCRIPTION

[0036] Example 1

[0037] In a typical embodiment of the present invention, Figure 1-Figure 10 As shown, a modular detachable air membrane facility is provided.

[0038] Traditional air-supported buildings have problems such as rigid connection methods, complex construction, and poor reusability. In practical applications, such as post-disaster reconstruction, temporary storage, mobile exhibition halls, etc., there is a need for an air-supported facility that can be quickly deployed, flexibly adjusted in scale, and efficiently constructed under limited construction conditions. However, existing air-supported buildings are difficult to meet these requirements, limiting the application and development of air-supported buildings in more fields. Based on this, the present embodiment provides a modular detachable air-supported facility, in which a plurality of air-supported modules are detachably connected using a connector 7, and the connector 7 adopts the matching form of a card slot 71 and a card block, and a card connection is formed between the card slot 71 and the card block. At the same time, the flexible magnet 72 provided on the card block can form a magnetic adsorption with the card slot 71 to ensure the stability of the card slot 71 and the card block after connection, and the gap at the card connection position is filled with an elastic pad to improve the sealing, thereby meeting the needs of rapid deployment and flexible adjustment.

[0039] like Figure 1 As shown, the modular detachable air film facility is composed of a plurality of air film modules that can be spliced ​​together. When these air film modules are spliced ​​together, a space with specific functions, namely a functional cavity, is naturally formed inside. At the splicing parts of the air film modules, connectors 7 are used to achieve a stable connection. The air film modules are produced in a factory prefabricated manner and can be transported and placed as a whole. Adjacent air film modules are spliced ​​together to form a splicing seam. The connector 7 is mainly composed of card slots 71 and card blocks that are orderly distributed along the splicing seam. The card slots 71 and the card blocks are distributed along the entire length of the splicing seam. After the adjacent air film modules are spliced ​​together, the splicing seam position uses the card slots 71 and the card blocks to form a stable connection and a good seal, which meets the requirements of the air film building for structural strength and sealing.

[0040] Among them, Figure 8 and Fig. 9As shown, the card slot 71 is provided with a recess for accommodating the card block, and the inner wall of the recess is tightly fitted with an elastic pad; the card slot 71 is a ferromagnetic metal sheet 711, which is bent to form a U-shaped cross-section groove structure, and the side walls of the metal sheet 711 corresponding to the two sides of the recess are bent multiple times to form the required serrated protrusions, and a flexible magnet 72 is provided on the card block, and the elastic pad can be a rubber pad 712, which is pasted on the side walls of the metal sheet 711 on both sides of the recess. When implementing the splicing operation, with the help of the inherent adsorption characteristics of the flexible magnet 72, the card block can be embedded in the recess of the card slot 71, thereby realizing the rapid connection between the air film modules. In this process, the elastic pad plays multiple roles: on the one hand, it effectively buffers the collision impact force generated by the card block and the card slot 71 at the moment of connection, avoiding structural damage that may be caused by hard contact; on the other hand, the card slot 71 and the card block squeeze the rubber pad 712, and the rubber pad 712 fully fills the connection gap between the card slot 71 and the card block after deformation, which significantly improves the sealing performance of the connection part and ensures that the sealing of the entire air membrane facility meets high standards.

[0041] like Figure 1 As shown, in terms of rapid assembly and disassembly performance, the design of the magnetic card slot 71 makes the splicing and disassembly operations of the air film module extremely simple and efficient, which can greatly shorten the construction period and is suitable for application scenarios that require rapid deployment, such as post-disaster reconstruction, temporary warehousing, and mobile exhibition halls. In terms of sealing performance, the intervention of the elastic pad fills the gap between the card block and the card slot 71, ensuring the overall sealing of the air film facility, allowing it to operate stably and reliably under various complex and harsh environmental conditions. The air film module and its connector 7 are both detachable and reusable, which reduces the long-term use cost and is suitable for application scenarios that require flexible adjustment of the scale according to actual conditions.

[0042] like Figure 8 and Fig. 9 As shown, the card slot 71 opens toward one side of the card block, and the inner wall of the recess is provided with a serrated protrusion, and the card block is correspondingly provided with a serrated groove, and the two are connected. The cooperation of the serrated protrusion and the serrated groove enhances the stability of the connection between the card slot 71 and the card block. Compared with simply relying on the adsorption of the flexible magnet 72, the serrated structure provides a mechanical bite, so that the air film module can still maintain a tight connection under the conditions of external pulling, vibration, etc., which greatly improves the overall structural strength and stability of the air film facility. The elastic pad is lined between the serrated protrusion and the groove, and follows the deformation of the serrated protrusion and the serrated groove. The elastic pad is connected to the card slot 71, which can not only buffer the impact force when the two are connected, but also use its deformation to ensure that good sealing performance can be maintained under various working conditions to avoid gas leakage.

[0043] like Figure 1As shown, in this embodiment, the air film module is composed of an arched basic module 4 and a partially spherical end module 1. The basic module 4 is the middle part of the entire air film facility, and the end module 1 blocks both ends of the middle part. Multiple basic modules 4 are spliced ​​in sequence through connectors 7, and the end modules 1 are spliced ​​at both ends of the basic modules 4. The combination of the basic module 4 and the end module 1 makes the shape of the air film facility more diverse and can meet different spatial layouts and functional requirements. Figure 4 As shown, the arched basic module 4 is conducive to dispersing the internal pressure and improving the bearing capacity of the air film; Figure 6 As shown, the partially spherical shell-shaped end module 1 can optimize the end structure of the air film facility and enhance the overall stability and aesthetics. At the same time, the modular splicing method makes the construction more convenient, and the scale and shape of the air film facility can be flexibly adjusted according to actual needs.

[0044] In order to meet the needs of personnel and vehicles entering and exiting the air membrane facility, as well as lighting and ventilation, various functional structures are preset on the basic module 4 and the end module 1 to form various functional modules. Figure 1 Taking the example shown, the modular detachable air membrane facility in this embodiment includes a lighting module 2, a ventilation and lighting module 3, a personnel entrance and exit module 5, a car entrance and exit module 6, etc.

[0045] Among them, Figure 5 As shown, a first entrance and exit is provided on the basic module 4 and a door assembly 51 is installed as a personnel entrance and exit module 5. The door assembly 51 includes a door 514, an air pressure sensor 511, a hydraulic rod and a controller 513. The door 514 is installed on the basic module 4 through a door frame. The door frame is connected and sealed to the air film module body. The air pressure sensor 511 of the door assembly 51 measures the air pressure near the door assembly 51 and sends it to the controller 513. One end of the hydraulic rod is connected to the door frame and the other end is connected to the door 514. The hydraulic rod is connected to the controller 513, and the controller 513 is used to control the action of the hydraulic rod.

[0046] In this embodiment, Fig.10 As shown, the door assembly 51 forms an intelligent opening and closing structure, the hydraulic rod is an articulated electric hydraulic rod 512, the air pressure sensor 511 is fixedly connected to the door frame, the air pressure sensor 511 monitors the air pressure near the door assembly 51 in real time and feeds back to the controller 513, and the controller 513 controls the action of the hydraulic rod according to the air pressure data, thereby realizing the automatic opening and closing of the door 514. In addition, the controller 513 calculates how much thrust the articulated electric hydraulic rod 512 needs to generate to assist in closing the door 514 by analyzing the data transmitted by the air pressure sensor 511; the controller 513 is fixedly connected to the door 514, which not only facilitates the entry and exit of personnel, but also effectively maintains the air pressure stability inside the air membrane facility, ensuring the normal operation of the air membrane.

[0047] like Figure 6As shown, a control room 61 and a second entrance and exit 62 are provided on the end module 1 as a vehicle entrance and exit module 6. The second entrance and exit 62 is used as a vehicle entrance and exit, which improves the function of the air film facility, so that it can meet the needs of both personnel passage and vehicle entry and exit, and expands the application scope of the air film facility. In this embodiment, the control room 61 and the second entrance and exit 62 both have an inner door 514 and an outer door 514, which can ensure that the gas inside the air film building is minimized from overflowing when personnel and vehicles enter and exit.

[0048] like Figure 2 As shown, a light-transmitting hole is opened on the basic module 4 and a light-transmitting film 21 is installed as the illumination module 2. A rectangular hole is taken at the top center of the basic module 4 as the light-transmitting hole. The light-transmitting hole is sealed by bonding the light-transmitting hole with the light-transmitting film 21 to form the required light-transmitting window, thereby ensuring that the interior of the closed air-film building has sufficient light, thereby ensuring the normal operation of the air-film. Figure 3 As shown, some lighting modules 2 are provided with ventilation holes and a fan 31 is installed as a ventilation lighting module 3. On the basis of the lighting module 2, ventilation holes are reserved to install the fan 31 to ensure air exchange inside and outside the air membrane, and the air intake and outlet can be adjusted according to the internal and external air pressure difference required by the air membrane building.

[0049] like Figure 7 As shown, the main body of the air film module is an air film body 8, and the air film module body is composed of an air film outer layer 81, an air film interlayer 83 and an air film inner layer 82. The air film interlayer 83 is filled in the cavity formed by the outer layer and the inner layer. The multi-layer structure design significantly improves the protective performance, thermal insulation performance and durability of the air film. The air film outer layer 81 can resist external physical impact, ultraviolet radiation, etc.; the air film interlayer 83 can play a role in heat insulation and reduce the loss of internal energy. The air film interlayer 83 is a thermal insulation material, which can ensure the temperature inside the air film during use; the air film inner layer 82 provides a smooth and comfortable interface for the internal space. The layers work together to enable the air film facility to operate stably under different climate and environmental conditions.

[0050] One side of the air membrane module is connected to the card slot 71, and the other side is connected to the card block, so that the direction of the air membrane module is clear when splicing, which is convenient for construction operation. At the same time, the regularity and stability of the splicing of the entire air membrane facility are guaranteed. The modular detachable air membrane facility is optimized and improved from multiple aspects such as connection structure, module composition, functional components and membrane structure, further strengthening the advantages of modular design.

[0051] Example 2

[0052] In another typical embodiment of the present invention, Figure 1-Figure 10 As shown, a construction method of a modular detachable air membrane facility is provided, using the modular detachable air membrane facility as in Example 1.

[0053] A construction method for a modular detachable air membrane facility, comprising:

[0054] Arrange multiple air film modules, and adjacent air film modules are spliced ​​together through the card slots 71 of the connector 7 and the card blocks, and the splicing positions form a splicing seam, and a functional cavity is formed inside the air film module;

[0055] During expansion, the joints at the set positions are removed, the air film modules on at least one side of the joints are moved, and new air film modules are installed to establish connections with other air film modules;

[0056] When shrinking the building, the joints at the set positions are removed, some air film modules are removed, the positions of other air film modules are adjusted, and the connections between the remaining air film modules are re-established.

[0057] Specifically, the construction method for constructing a modular detachable air film facility in this embodiment is centered on the splicing of air film modules, and the operation process is simple and clear. In the initial construction stage, it is only necessary to arrange multiple air film modules according to the plan, and use the card slot 71 of the connector 7 and the card block to splice them, so that an air film facility with a functional cavity inside can be quickly constructed. Compared with traditional building construction, the modular splicing method does not require complicated on-site pouring, hot melt welding and other processes, which greatly shortens the construction period and reduces the construction difficulty. It is particularly suitable for scenes with limited construction conditions.

[0058] In terms of facility scale adjustment, when expansion is needed, it is only necessary to remove the joints at the set position and move the air film modules on one side to place the new air film modules and re-establish the connection, thus easily expanding the scale of the air film facility. When reducing the scale, it is necessary to remove specific joints, remove some air film modules, adjust the positions of the remaining modules and reconnect them. The whole process is easy to operate and can flexibly change the size and layout of the air film facility according to actual needs, fully meeting the needs for dynamic adjustment of the scale of air film facilities in different scenarios.

[0059] The card block is connected to the card slot 71, and under the combined effect of the internal pressure of the functional cavity and the elastic pad, a good seal is achieved at the joint position. The internal pressure of the functional cavity will make the connection between the card block and the card slot 71 tighter, and the elastic pad fills the slight gap between the two, further enhancing the sealing effect. It not only ensures the stability of the air pressure inside the air film facility and ensures that the air film can be supported normally, but also effectively prevents the entry of impurities such as dust and rainwater from the outside, thereby improving the safety and durability of the air film facility.

[0060] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
