Description

Technical Field

[0001] This invention relates to the field of wind-resistant technology for movable membrane materials for membrane building ventilation openings, and particularly to an inflatable extrusion assembly and its application method on greenhouse facades and roof structures. Background Technology

[0002] The membrane structure envelope is composed of membrane materials, including fixed and movable membrane materials. Movable membrane materials are used for ventilation openings, while fixed membrane materials are used for the remaining areas. Traditionally, the movable membrane material is engaged with the steel structure by retracting and extending a roll-up rod, allowing for the sealing and unsealing of ventilation openings. When the roll-up rod retracts the membrane material, the ventilation opening opens; when the membrane material is lowered, the ventilation opening closes (e.g., ...). Figure 16 (As shown). Figure 16 The image shows a stand-alone film arched canopy with a total height of about 3 meters and a width of about 1 meter along the top and bottom edges of the ventilation openings. To resist wind loads, the fixed and movable membrane materials are usually secured to the steel structure with membrane-pressing ropes.

[0003] However, the tightness of the membrane structure tension rope directly affects the smoothness of the boom rotation. While overly tight ropes enhance wind resistance, they also cause excessive pressure between the boom and the steel structure, making rotation difficult. Conversely, overly loose ropes, while facilitating operation, compromise wind stability. Therefore, a contradiction exists between wind resistance and boom rotation, especially when the membrane structure's height exceeds 9 meters, the width of the facade ventilation openings exceeds 4 meters, and its length extends to over 100 meters. Figure 16 The traditional membrane pressing rope shown is difficult to continuously and reliably fix the movable membrane material and the roller. Under strong winds, the large-area movable membrane material, roller and membrane pressing rope system are easily damaged by the wind.

[0004] In practice, to mitigate the risk of wind damage, some users are forced to reduce the width of ventilation openings to less than 1 meter. While this method improves safety, it severely limits ventilation efficiency, resulting in hot indoor air not being effectively expelled in summer, with room temperature reaching over 50°C, seriously affecting usability. Summary of the Invention

[0005] The purpose of this invention is to provide an inflatable extrusion assembly and its application method on the exterior facade or roof structure of a greenhouse, thereby solving the aforementioned problems existing in the prior art.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: This invention discloses an inflatable extrusion assembly for use in the enclosure structure of membrane structures where frequent sealing and unsealing are required. Inflation compresses the movable membrane material and the roll rod for holding the movable membrane material against the steel structure. Deflating releases the compression on the movable membrane material and the roll rod, allowing the roll rod to be rotated to either seal the area of ​​the steel structure where the movable membrane material is located or to remove the membrane material from the steel structure to release the seal. The assembly includes strip-shaped air chambers, strip-shaped limiting chambers, tie rods, and an inflation / deflator mechanism. Two of the strip-shaped air chambers... The limiting cavities are arranged in parallel with a spacing corresponding to the outer diameter of the strip-shaped air cavity after it is inflated into a column shape. The strip-shaped air cavity is located between the two strip-shaped limiting cavities and is arranged parallel to them. The two tie rods are respectively inserted into the two strip-shaped limiting cavities, and the length of the tie rod is greater than the length of the strip-shaped limiting cavity. The length of the strip-shaped air cavity and the strip-shaped limiting cavity corresponds to the width of the extruded movable membrane material. The diameter of the strip-shaped air cavity after inflation corresponds to the total outer diameter of the extruded roll rod after it is wound around the movable membrane material. The two ends of the tie rod are connected to the steel structure of the enclosure structure where sealing and unsealing are frequently required. The strip-shaped air cavity is limited to working on one side between the two strip-shaped limiting cavities. The inflation and deflation mechanism is sealed and connected to the strip-shaped air cavity through the cavity wall of the preset part of the strip-shaped air cavity. The strip-shaped air cavity is inflated and deflated by the inflation and deflation mechanism. After the strip-shaped air cavity is inflated, it expands towards the steel structure and squeezes the movable membrane and the roll rod onto the steel structure. After the strip-shaped air cavity is deflated, the movable membrane is arranged or separated on the steel structure under the rotation of the roll rod.

[0007] Furthermore, the strip-shaped air cavity and the strip-shaped limiting cavity are formed by extruding plastic resin raw materials in a molten state through a first preset mold, so that the cavity wall of the strip-shaped air cavity and the cavity wall of the strip-shaped limiting cavity are integrated, sealing both ends of the strip-shaped air cavity, and connecting the inflation and deflation mechanism to the sealed cavity wall to make the first inflatable extrusion assembly.

[0008] Furthermore, the strip-shaped air cavity and the strip-shaped limiting cavity are made of cylindrical membrane material through a first type of preset heat sealing equipment, so that the cavity wall of the strip-shaped air cavity and the cavity wall of the strip-shaped limiting cavity are directly connected together at the heat sealing seam, sealing both ends of the strip-shaped air cavity, and connecting the inflation and deflation mechanism to the sealed cavity wall to form a second type of inflatable extrusion assembly.

[0009] Furthermore, the strip-shaped air cavity and the strip-shaped limiting cavity are respectively made of strip-shaped air cavity membrane material, strip-shaped limiting cavity membrane material and first strip-shaped connecting wall through a second type of preset heat sealing equipment. The cavity wall of the strip-shaped air cavity and the cavity wall of the strip-shaped limiting cavity are connected as one unit through the first strip-shaped connecting wall. The first strip-shaped connecting wall is located between the cavity wall of the strip-shaped limiting cavity and the cavity wall of the strip-shaped air cavity, sealing both ends of the strip-shaped air cavity. The inflation and deflation mechanism is connected to the sealed cavity wall to form a third type of inflatable extrusion assembly.

[0010] Furthermore, a second strip-shaped connecting wall is provided between the two strip-shaped limiting cavities. The two strip-shaped limiting cavities and the second strip-shaped connecting wall are formed into an integral structure by extruding plastic resin raw materials in a molten state through a second type of preset mold. The strip-shaped air cavity is welded to one side of the second strip-shaped connecting wall by a strip-shaped air cavity membrane material through a third type of heat sealing equipment, sealing both ends of the strip-shaped air cavity. The inflation and deflation mechanism is connected to the sealed cavity wall to form a fourth type of inflatable extrusion assembly.

[0011] Furthermore, a second strip-shaped connecting wall is provided between the two strip-shaped limiting cavities. The two strip-shaped limiting cavities and the second strip-shaped connecting wall are formed into an integral structure by extruding plastic resin raw materials in a molten state through a second preset mold. A membrane material hoop is welded at intervals on one side of the second strip-shaped connecting wall. A cylindrical membrane material liner is provided inside the membrane material hoop as the strip-shaped air cavity. The two ends of the strip-shaped air cavity are sealed. The inflation and deflation mechanism is connected to the sealed cavity wall to form a fifth type of inflatable extrusion assembly.

[0012] The present invention also provides a method for using an inflatable extrusion assembly on a greenhouse facade structure, including the aforementioned inflatable extrusion assembly and a greenhouse facade structure. The facade structure is arranged on the ground and / or on windows in the air. The facade structure includes facade beams, facade columns, movable membrane material, and roller rods. The facade columns are spaced apart below the facade beams and support and connect to the facade beams. The upper edge of the movable membrane material is fixedly connected to the facade beams. The movable membrane material is attached to the outer side of the facade columns and hangs freely. The roller rods are arranged parallel to the facade beams at the lower end of the movable membrane material, and the roller rods are wound and connected to the lower end of the movable membrane material. A tie rod connecting arm is provided on the facade beam at the upper end of the movable membrane material, and a tie rod fastening seat is provided at the lower end of the facade column. The horizontal extension length of both the tie rod connecting arm and the tie rod fastening seat is greater than the outer diameter of the roll rod. The inflatable extrusion assembly is located on the outside of the movable membrane material and is arranged vertically corresponding to the facade column. The upper end of the tie rod is connected to the tie rod connecting arm and the lower end is connected to the tie rod fastening seat so that the tie rod is in a taut state. The method of use includes the following steps: When it is necessary to wrap the movable membrane material around the roller and move it upward with the roller to release the facade blockage, the inflation and deflation mechanism is activated to deflate the strip-shaped air chamber, reducing the pressure on the roller and the movable membrane material. The roller is then rotated to wrap the movable membrane material around it. The roller carries the movable membrane material upward to a preset position and stops. The inflation and deflation mechanism is then activated again to inflate the strip-shaped air chamber. After the strip-shaped air chamber expands, it presses the roller and the movable membrane material against the facade column, preventing the movable membrane material and the roller from swaying in the wind. When it is necessary to release the movable membrane material from the roller and move it downwards with the roller to seal the facade, the inflation and deflation mechanism is activated to deflate the strip-shaped air chamber, reducing the pressure on the roller and the movable membrane material. The roller is then rotated to release the movable membrane material from the roller. The movable membrane material moves downwards with the roller to a preset position and stops. The inflation and deflation mechanism is then activated again to inflate the strip-shaped air chamber. After the strip-shaped air chamber expands, it once again presses the roller and the movable membrane material against the facade column, preventing the movable membrane material and the roller from swaying in the wind.

[0013] The present invention also provides a method for using an inflatable extrusion assembly on a greenhouse roof structure, comprising the aforementioned inflatable extrusion assembly, a ridge beam, an arch frame structure, a movable membrane material, and a roller rod. The top end of the arch frame structure is perpendicularly and fixedly connected to the ridge beam. The upper edge of the movable membrane material is fixedly connected to the ridge beam. The movable membrane material is attached to the outer side of the arch frame structure and extends freely downwards. The roller rod is arranged parallel to the ridge beam at the lower end of the movable membrane material, and the roller rod is wound and connected to the lower end of the movable membrane material. A tie rod connecting pile is provided on the ridge beam at the upper end of the movable membrane material, and a tie rod fastening pile is provided at the lower end of the arch frame structure. The inflatable extrusion assembly is provided on the outside of the movable membrane material corresponding to the arch frame structure. The tie rod is arranged in an arc along the arch frame structure. The upper end of the tie rod is connected to the tie rod connecting pile and the lower end is connected to the tie rod fastening pile so that the tie rod is in a taut state. The method of use includes the following steps: When it is necessary to wind the movable membrane material around the roller and move it closer to the ridge beam to release the roof blockage, the inflation and deflation mechanism is activated to deflate the strip-shaped air chamber, reducing the pressure on the roller and the movable membrane material. The roller is then rotated to wind the movable membrane material around it. The roller carries the movable membrane material and moves it closer to the ridge beam to a preset position and stops. The inflation and deflation mechanism is then activated again to inflate the strip-shaped air chamber. After the strip-shaped air chamber expands, it presses the roller and the movable membrane material against the arch structure, preventing the movable membrane material and the roller from bobbing up and down in the wind. When it is necessary to release the movable membrane material from the roller and move it away from the ridge beam to seal the roof, the inflation and deflation mechanism is activated to deflate the strip-shaped air chamber, reducing the pressure on the roller and the movable membrane material. The roller is then rotated to release the movable membrane material from it. The movable membrane material moves away from the ridge beam with the roller and stops at a preset position. The inflation and deflation mechanism is then activated again to inflate the strip-shaped air chamber. After the strip-shaped air chamber expands, it once again presses the roller and the movable membrane material against the arch structure, preventing the movable membrane material and the roller from bobbing up and down in the wind.

[0014] Compared with the prior art, the beneficial technical effects of the present invention are as follows: The inflatable extrusion assembly of this invention and its application method on the exterior facade or roof structure of a greenhouse achieves rapid and reliable switching between the compression state through dynamic control of inflation and deflation. When inflated, it provides strong and uniform frontal pressure, ensuring the stability of the movable membrane material and the roll rod in windy weather. When deflated, it instantly releases pressure, minimizing the resistance to roll rod rotation and making operation easy. This completely overcomes the inherent defects of traditional membrane-pressing ropes, which are difficult to rotate when compressed and have poor wind resistance when loose, due to the difficulty in achieving a balance between tightness and looseness. Furthermore, the extrusion assembly can be arranged along the entire length of the steel structure to form a continuous and uniform compression force, solving the problem of discrete compression in traditional membrane-pressing ropes. The uneven pressure caused by this invention allows it to be reliably applied to large ventilation openings with a height of over 9 meters, a width of over 4 meters, and a length of over 100 meters, breaking through the technical bottleneck of traditional methods in the application of large-scale membrane buildings. At the same time, this invention makes it possible to enlarge the vertical height of facade ventilation openings or roof ventilation openings to almost the same height as the facade. This design of maximizing ventilation openings ensures extremely smooth air convection inside and outside the greenhouse, effectively eliminating the hot air accumulated inside, and reducing the maximum indoor temperature in summer to basically the same as the outdoor natural environment. This fundamentally solves the problem of high temperature and stuffiness in greenhouses caused by the forced reduction of ventilation openings due to fear of wind disasters.

Detailed Implementation

[0018] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0019] In the description of this invention, it should be understood that the terms "length," "width," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0020] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0021] The technical solutions provided by the various embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0022] Example 1 like Figures 1 to 10 As shown, the inflatable extrusion assembly 30 of this embodiment 1 is used in the enclosure structure of membrane buildings where frequent sealing and unsealing are required. Through the inflation operation, the movable membrane material 3 of the enclosure structure and the roll rod 4 for rolling the movable membrane material 3 can be squeezed together and pressed against the steel structure 1. Through the deflation operation, the compression on the movable membrane material 3 and the roll rod 4 can be released so that the roll rod 4 can be rotated to cover the steel structure 1 at the location of the movable membrane material 3 to seal it or to remove the steel structure 1 at the location to unseal it. At this time, if the location is a facade, the steel structure 1 at the location is a facade column 12; if the location is an arched roof, the steel structure 1 at the location is an arch frame 22.

[0023] The inflatable extrusion assembly 30 of this embodiment 1 includes a strip-shaped air chamber 40, a strip-shaped limiting cavity 41, a tie rod 42, and an inflation / deflation mechanism 43. The length of the strip-shaped air chamber 40 corresponds to the width of the movable membrane material 3 being extruded, so that after inflation, most of the movable membrane material 3 can be extruded onto the steel structure 1 at the location in the width direction. The diameter of the strip-shaped air chamber 40 is slightly larger than the diameter of the winding rod 4, to ensure that after the movable membrane material 3 is completely wrapped around the winding rod 4, the winding rod 4 can still be accommodated in the space between the deflated strip-shaped air chamber 40 and the steel structure 1 at the location. This is related to the diameter of the winding rod 4 body and the width and thickness of the movable membrane material 3. The length of the strip-shaped limiting cavity 41 corresponds to the length of the strip-shaped air chamber 40, so that the strip-shaped limiting cavity 41 can cover most of the strip-shaped air chamber 40. The limiting function is implemented by arranging two strip-shaped limiting cavities 41 in parallel with each other. The distance between them corresponds to the outer diameter of the strip-shaped air cavity 40 after it is inflated into a column shape. The strip-shaped air cavity 40 is located between the two strip-shaped limiting cavities 41 and is arranged in parallel with them. This ensures that the center of force when the strip-shaped air cavity 40 is inflated and exerts a squeezing effect on the movable membrane material 3 and the roll rod 4 will not deviate, but will be centered between the two strip-shaped limiting cavities 41. This ensures that the working state of the inflatable extrusion assembly 30 is stable. The inner diameter of the strip-shaped limiting cavity 41 corresponds to the outer diameter of the tie rod 42. This ensures that after the tie rod 42 is connected to the strip-shaped limiting cavity 41, the strip-shaped limiting cavity 41 will not shake significantly in windy weather, causing severe friction with the tie rod 42 and shortening its service life. The length of the tie rod 42 is greater than the length of the strip-shaped limiting cavity 41.

[0024] A film greenhouse is a type of membrane architecture. The enclosure structure of a film greenhouse is a film. The steel structure 1 of the film greenhouse includes the facade columns 12 in the ground-level facade structure 10, the facade columns 12 in the air-level window structure, and the arch frame 22 in the arched roof. The parts of the film greenhouse that need to be frequently sealed and unsealed include the facade ventilation openings 6, the window ventilation openings 7, and the ridge ventilation openings 8 in the arched roof. The movable membrane material 3 arranged at these ventilation openings is usually a film, but it can also be other types of roll materials, such as shade net roll materials, foamed heat insulation roll materials, etc. This invention does not impose any restrictions. Inflating the inflatable extrusion assembly 30 compresses the membrane against the facade columns 12 and arches 22 to prevent wind damage. Deflating the inflatable extrusion assembly 30 releases the pressure on the membrane, allowing the rotating rod 4 to wind or release the movable membrane material 3. This correspondingly removes or covers the facade columns 12 and arches 22 at their locations. The facade ventilation openings 6, window ventilation openings 7, and ridge ventilation openings 8 are either unsealed or sealed. The strip-shaped air chamber 40 is then inflated again to maintain this state. The strip-shaped air chamber 40 is a flexible structure that can be sealed at both ends to form a strip-shaped air bladder. When deflated, it collapses into a deflated shape, thus losing its compressive effect on the rotating rod 4. The strip-shaped limiting cavity 41 is a strip-shaped sleeve structure used to keep the strip-shaped air chamber 40 in a preset working state. The tie rod 42 is a steel bar or spring steel bar of a preset diameter, or other wire with a preset tensile strength.

[0025] Optional, such as Figure 1 , Figure 3 As shown, the strip-shaped air cavity 40 and the strip-shaped limiting cavity 41 are formed by extruding plastic resin raw material in a molten state through a first preset mold 51, so that the cavity wall of the strip-shaped air cavity 40 and the cavity wall of the strip-shaped limiting cavity 41 are fused together, sealing both ends of the strip-shaped air cavity 40. An inflation / deflation mechanism 43 is connected to the sealed cavity wall to form the first inflatable extrusion assembly 30. Wherein, as... Figure 2 As shown, the first type of preset mold 51 is a common means of plastic resin extrusion molding or blow molding process. The inflation and deflation mechanism 43 can be a miniature blower with an air valve, which is directly connected to the wall of the strip-shaped air chamber 40 and works in a preset manner. Alternatively, it can be an air pipe with an air valve and a Roots blower assembly, with the air pipe connecting the strip-shaped air chamber 40 to the Roots blower. The present invention does not limit the inflation and deflation mechanism 43.

[0026] Optional, such as Figure 4 As shown, the strip-shaped air cavity 40 and the strip-shaped limiting cavity 41 are made of cylindrical membrane material 71 through a first type of pre-set heat sealing device 61, so that the cavity wall of the strip-shaped air cavity 40 and the cavity wall of the strip-shaped limiting cavity 41 are directly connected together at the heat sealing seam, sealing both ends of the strip-shaped air cavity 40. An inflation / deflation mechanism 43 is then connected to the sealed cavity wall to form a second type of inflatable extrusion assembly 30. Wherein, as... Figure 5As shown, the tubular membrane 71 is a circular closed-loop roll of material with a preset diameter, made by plastic resin extrusion molding or blow molding. It is stretched into a tubular shape. The first type of preset heat sealing equipment 61 includes at least a set of vertical clamping roller assembly 81, a set of horizontal support roller assembly 82, and two electro-heat sealing mechanisms 83. The tubular membrane 71 is squeezed into a T-shape 84 with inner wall abutting by the cooperation of the vertical clamping roller assembly 81 and the horizontal support roller assembly 82. The T-shape 84 can also be pre-folded by the preset folding equipment after the tubular membrane 71 is made by plastic resin extrusion molding or blow molding. The two electro-heat sealing mechanisms 83 perform heat sealing connection on the two preset parts of the T-shape 84, so that the tubular membrane 71, which originally has a large cavity, becomes a strip-shaped limiting cavity 41 with a large cavity and two small cavities and a strip-shaped air cavity 40. It should be noted that there are various processes for processing the cylindrical membrane material 71 into strip-shaped limiting cavity 41 and strip-shaped air cavity 40, and the present invention does not limit the process.

[0027] Optional, such as Figure 6 As shown, the strip-shaped air cavity 40 and the strip-shaped limiting cavity 41 are respectively made of strip-shaped air cavity membrane material 72, strip-shaped limiting cavity membrane material 73, and first strip-shaped connecting wall 74 through a second type of pre-set heat sealing device 62. The cavity wall of the strip-shaped air cavity 40 and the cavity wall of the strip-shaped limiting cavity 41 are connected as one unit through the first strip-shaped connecting wall 74. The first strip-shaped connecting wall 74 is located between the cavity wall of the strip-shaped limiting cavity 41 and the cavity wall of the strip-shaped air cavity 40, sealing both ends of the strip-shaped air cavity 40. An inflation and deflation mechanism 43 is connected to the sealed cavity wall to form a third type of inflatable extrusion assembly 30. Among them, as shown in the figure... Figure 7 As shown, the second type of pre-heat sealing device 62 includes at least one set of vertical clamping roller assembly 81, one set of horizontal support roller assembly 82, and four electro-heat sealing mechanisms 83. The strip-shaped air cavity membrane 72 is pre-folded into a T-shape 84. The middle part of the T-shaped strip-shaped air cavity membrane 72 is rolled and clamped by the vertical clamping roller assembly 81. The two sides of the T-shaped strip-shaped air cavity membrane 72 are laid on top of the first strip-shaped connecting wall 74, which is rolled and supported by the horizontal support roller assembly 82. The two strip-shaped limiting cavity membranes 73 are below the first strip-shaped connecting wall 74. The roller assemblies 85 of the four electro-heat sealing mechanisms 83 simultaneously heat seal the two sides of the strip-shaped air cavity membrane 72 and the two sides of the strip-shaped limiting cavity membrane 73 to the two sides of the first strip-shaped connecting wall 74, so that the original one strip-shaped air cavity membrane 72, one first strip-shaped connecting wall 74, and two strip-shaped limiting cavity membranes 73 become a strip-shaped limiting cavity 41 and a strip-shaped air cavity 40 with a large cavity and two small cavities. There are many ways to form a strip-shaped air cavity membrane 72, a first strip-shaped connecting wall 74, and two strip-shaped limiting cavity membranes 73 into a strip-shaped limiting cavity 41 and a strip-shaped air cavity 40, and the present invention does not limit them.

[0028] Optional, such as Figure 8As shown, a second strip-shaped connecting wall 75 is provided between the two strip-shaped limiting cavities 41. The two strip-shaped limiting cavities 41 and the second strip-shaped connecting wall 75 are formed into an integral structure by extruding plastic resin raw materials in a molten state through a second type of pre-set mold. The forming principle of the second type of pre-set mold is the same as that of the first type of pre-set mold 51. The strip-shaped air cavity 40 is formed by welding the strip-shaped air cavity membrane material 72 to one side of the second strip-shaped connecting wall 75 through a third type of pre-set heat sealing equipment 63, sealing both ends of the strip-shaped air cavity 40. An inflation and deflation mechanism 43 is connected to the sealed cavity wall to form a fourth type of inflatable extrusion assembly 30. As shown in the figure... Figure 9 As shown, the strip-shaped air cavity membrane 72 is pre-folded into a T-shape 84. The T-shape 84 and the second strip-shaped connecting wall 75 are fed into two rows of electrothermal sealing mechanisms 83 on both sides under the cooperation of the vertical clamping roller assembly 81 and the horizontal support roller assembly 82. They are then heat-sealed to form two heat-sealing lines, so that the originally independent strip-shaped air cavity membrane 72 and the second strip-shaped connecting wall 75 with two small cavities together constitute the cavity wall of the strip-shaped air cavity 40 and the cavity wall of the strip-shaped limiting cavity 41, and are indirectly connected together through the second strip-shaped connecting wall 75.

[0029] Optional, such as Figure 10 As shown, a second strip-shaped connecting wall 75 is provided between the two strip-shaped limiting cavities 41. The two strip-shaped limiting cavities 41 and the second strip-shaped connecting wall 75 are formed into an integral structure by extruding plastic resin raw materials in a molten state through a second type of preset mold. Membrane material hoop rings 76 are welded at intervals on one side of the second strip-shaped connecting wall 75. A cylindrical membrane material liner 77 is provided inside the membrane material hoop ring 76 as a strip-shaped air cavity 40. The two ends of the strip-shaped air cavity 40 are sealed. An inflation and deflation mechanism 43 is connected to the sealed cavity wall to form a fifth type of inflatable extrusion assembly 30.

[0030] The sealing method at both ends of the strip-shaped air cavity 40 is not limited. For example, the inner walls near both ends of the strip-shaped air cavity 40 can be joined together by heat sealing to achieve a seal.

[0031] Preferably, the inflation / deflation mechanism 43 includes an air pipe and a blower valve device. The blower valve device is connected to the tie rod 42 or the steel structure 1. The air pipe is sealed to the cavity wall of the strip-shaped air chamber 40 and is connected to the blower valve device. When the blower rotates in the forward direction, the valve opens, and outside air enters the strip-shaped air chamber 40 under positive pressure through the valve and the air pipe. After inflation is completed, the valve closes. When the blower rotates in the reverse direction, the valve opens, and the air in the strip-shaped air chamber 40 is drawn out under negative pressure through the valve and the air pipe, thus deflating the air.

[0032] In this embodiment 1, the two ends of the tie rod 42 are connected to the steel structure 1 of the enclosure structure where the sealing and unsealing are frequently required, so that the movable membrane 3 and the roll rod 4 of this part are located between the strip-shaped air cavity 40 and the steel structure 1. The strip-shaped air cavity 40 is confined to one side between two strip-shaped limiting cavities 41. The inflation and deflation mechanism 43 is sealed and connected to the strip-shaped air cavity 40 through the cavity wall of the preset part of the strip-shaped air cavity 40. The strip-shaped air cavity 40 is inflated by the inflation and deflation mechanism 43. Due to the limiting effect of the strip-shaped limiting cavity 41 and the tie rod 42, the strip-shaped air cavity 40 can only expand towards the steel structure 1 after inflation, and squeeze the movable membrane 3 and the roll rod 4 onto the steel structure 1. After the strip-shaped air cavity 40 is deflated by the inflation and deflation mechanism 43, the movable membrane 3 can be arranged or separated on the steel structure 1 by rotating the roll rod 4. Among them, the two ends of the tie rod 42 are connected to the steel structure 1 of the membrane building enclosure structure, which requires frequent sealing and unsealing, through a pre-set special connector.

[0033] The inflatable compression assembly 30 in this embodiment 1, through the provision of an inflatable and deflated strip-shaped air chamber 40, a strip-shaped limiting chamber 41 providing stable positioning, and a tie rod 42, together constitute a dynamic compression structure. This structure effectively solves the inherent contradiction between wind resistance and smooth rolling in traditional membrane rope methods: when inflated, it ensures the stability of the movable membrane material 3 and the rolling rod 4 in windy weather; when deflated, it can instantly release pressure, making the rotation of the rolling rod 4 extremely easy. This characteristic allows the present invention to be reliably applied to large and even super-large ventilation openings. Utilizing the movable membrane material 3 of the protective membrane structure ventilation opening of the present invention, whether on a floor-to-ceiling facade or a roof window, the width between the upper and lower edges of the ventilation opening can be enlarged to almost the same height as the facade, thereby ensuring extremely smooth air convection inside and outside the greenhouse, efficiently eliminating the accumulated hot air inside the greenhouse, and making the highest indoor temperature in summer almost the same as the outdoor temperature, completely solving the problem of extreme indoor high temperatures caused by the forced reduction of ventilation openings due to fear of wind disasters. In addition, the flexible extrusion method provides uniform pressure distribution, making it less prone to wear on the membrane material. Furthermore, the strip-shaped limiting cavity 41 effectively suppresses system shaking, significantly extending the service life of the overall component.

[0034] Example 2 The method of using the inflatable extrusion assembly 30 on the greenhouse exterior structure 10 in this embodiment 2 includes the inflatable extrusion assembly 30 and the greenhouse exterior structure 10. The exterior structure 10 is arranged on the ground 9 and / or on the windows in the air. The exterior structure 10 includes facade beams 11, facade columns 12, movable membrane 3 and roller rods 4. The facade columns 12 are arranged at intervals below the facade beams 11 and support and connect to the facade beams 11. The upper edge of the movable membrane 3 is fixedly connected to the facade beams 11. The movable membrane 3 is attached to the outer side of the facade column 12 and hangs freely. The roller rods 4 are arranged parallel to the facade beams 11 at the lower end of the movable membrane 3, and the roller rods 4 are wound and connected to the lower end of the movable membrane 3.

[0035] Among them, a tie rod connecting arm 13 is provided on the facade beam 11 at the upper end of the movable membrane material 3, and a tie rod fastening seat 14 is provided at the lower end of the facade column 12. The horizontal extension length of the tie rod connecting arm 13 and the tie rod fastening seat 14 is greater than the outer diameter of the roll rod 4. The inflatable extrusion assembly 30 is provided on the outside of the movable membrane material 3 and is arranged vertically corresponding to the facade column 12. The upper end of the tie rod 42 is connected to the tie rod connecting arm 13 and the lower end is connected to the tie rod fastening seat 14 so that the tie rod 42 is in a taut state.

[0036] The method of use includes the following steps: When it is necessary to wrap the movable membrane material 3 around the roller 4 and move it upward with the roller 4 to release the facade blockage, the inflation and deflation mechanism 43 is activated to deflate the strip-shaped air chamber 40, reducing the pressure on the roller 4 and the movable membrane material 3. The roller 4 is rotated to wrap the movable membrane material 3 around the roller 4. The roller 4 carries the movable membrane material 3 upward to the preset position and stops. The inflation and deflation mechanism 43 is activated again to inflate the strip-shaped air chamber 40. After the strip-shaped air chamber 40 expands, it presses the roller 4 and the movable membrane material 3 against the facade column 12 to prevent the movable membrane material 3 and the roller 4 from swaying in the wind. When it is necessary to release the movable membrane material 3 from the roller 4 and move it downward with the roller 4 to seal the facade, the inflation and deflation mechanism 43 is activated to deflate the strip-shaped air chamber 40, reducing the pressure on the roller 4 and the movable membrane material 3. The roller 4 is rotated to release the movable membrane material 3 from the roller 4. The movable membrane material 3 moves downward with the roller 4 to a preset position and stops. The inflation and deflation mechanism 43 is activated again to inflate the strip-shaped air chamber 40. After the strip-shaped air chamber 40 expands, it once again presses the roller 4 and the movable membrane material 3 against the facade column 12, preventing the movable membrane material 3 and the roller 4 from swaying in the wind.

[0037] like Figure 11The diagram shows a plan view of the application of the inflatable extrusion assembly 30 on the facade structure 10. The facade structure 10 can be a ground-level facade ventilation opening 6 and / or an aerial window ventilation opening 7, which includes facade columns 12 and facade beams 11, and is a component of the membrane structure steel structure 1. On the outer vertical surface of the facade beam 11, two membrane material fixing connectors 15 are arranged horizontally at intervals: the upper one is used to fix the bottom edge of the fixed membrane material 2 arranged on the roof, and the lower one is used to fix the top edge of the movable membrane material 3 wound on the roller 4. A tie rod connecting arm 13 is provided in the gap between the two membrane material fixing connectors 15. One end of the tie rod connecting arm 13 is fixedly connected to the facade beam 11, and the other end extends outward to connect to the upper end of the tie rod 42 of the inflatable extrusion assembly 30. A tie rod fastening seat 14 is provided at the bottom end of the facade column 12 to achieve a taut connection with the lower end of the tie rod 42 of the inflatable extrusion assembly 30. The specific method of tightening the connection is not limited. For example, a bolt and nut fastening method can be used, that is, a bolt is set at the lower end of the tie rod 42 and a nut is fitted on the tie rod fastening seat 14. The upper end of the movable membrane 3 is fixedly connected to the membrane fixing connector 15 of the facade beam 11, and its bottom edge is wrapped and connected to the roller rod 4. The movable membrane 3 and the roller rod 4 are confined between the strip-shaped air cavity 40 and the facade column 12. When the air pressure in the strip-shaped air cavity 40 reaches the preset value, the roller rod 4 and the movable membrane 3 are squeezed and fixed to the facade column 12 to effectively resist the influence of wind load. In practice, a fixed membrane 2 with a preset width is also provided at the lower part of the facade structure 10. When the movable membrane 3 is lowered to the lowest position with the roller rod 4, the movable membrane 3 and the fixed membrane 2 will partially overlap, which will play a good airtight insulation role.

[0038] like Figure 12 The diagram shows a plan view of the application of the inflatable extrusion assembly 30 on the three facade structures 10 of the membrane building. The roof truss structure 25 is supported at both ends by facade beams 11. The area below the facade beams 11 forms facade ventilation openings 6. Asymmetrical arches 22 are installed on the roof truss structure 25, thus forming vertical window ventilation openings 7. The facade columns 12 at these vertical window ventilation openings 7 are part of the roof truss structure 25. When the facade ventilation openings 6 on both sides and the vertical window ventilation opening 7 at the top are all open, a large-scale air convection can be formed inside and outside the membrane building, effectively promoting ventilation.

[0039] Example 3 The method of using the inflatable extrusion assembly 30 on the greenhouse roof structure 20 in this embodiment includes the inflatable extrusion assembly 30, the ridge beam 21, the arch frame structure 22, the movable membrane 3, and the roll rod 4. The top of the arch frame structure 22 is perpendicularly and fixedly connected to the ridge beam 21. The upper edge of the movable membrane 3 is fixedly connected to the ridge beam 21. The movable membrane 3 is attached to the outer side of the arch frame structure 22 and hangs naturally. The roll rod 4 is arranged parallel to the ridge beam 21 at the lower end of the movable membrane 3, and the roll rod 4 is wound and connected to the lower end of the movable membrane 3.

[0040] Among them, the ridge beam 21 at the upper end of the movable membrane 3 is provided with tie rod connecting piles 23, the lower end of the arch frame structure 22 is provided with tie rod fastening piles 24, the inflatable extrusion assembly 30 is provided on the outside of the movable membrane 3 corresponding to the arch frame structure 22, the tie rod 42 is arranged in an arc along the arch frame structure 22, the upper end of the tie rod 42 is connected to the tie rod connecting pile 23 and the lower end is connected to the tie rod fastening pile 24, so that the tie rod 42 is in a taut state.

[0041] The method of use includes the following steps: When it is necessary to wind the movable membrane material 3 around the roller 4 and move it closer to the ridge beam 21 to open the ridge ventilation opening 8, the strip-shaped air chamber 40 is deflated by the inflation and deflation mechanism 43 to release the pressure on the roller 4 and the movable membrane material 3; the roller 4 is rotated to wind the movable membrane material 3 around the roller 4, so that the roller 4 carries the movable membrane material 3 to move towards the ridge beam 21 to the preset opening position; the strip-shaped air chamber 40 is inflated by the inflation and deflation mechanism 43, so that the strip-shaped air chamber 40 expands and firmly presses the roller 4 and the remaining movable membrane material 3 onto the arch structure 22 to prevent it from undulating under the action of wind. When it is necessary to release the movable membrane 3 from the roller 4 and move it away from the ridge beam 21 to close the ridge ventilation opening 8, the strip-shaped air chamber 40 is deflated by the inflation and deflation mechanism 43 to release the pressure on the roller 4 and the movable membrane 3; the roller 4 is rotated to release the movable membrane 3, so that the movable membrane 3 moves away from the ridge beam 21 to the preset closed position; the strip-shaped air chamber 40 is inflated by the inflation and deflation mechanism 43, so that the strip-shaped air chamber 40 expands and firmly presses the roller 4 and the movable membrane 3 onto the arch frame structure 22 to ensure a sealed state and prevent swaying under wind load.

[0042] like Figure 13 The diagram shows a plan view of the application of the inflatable extrusion assembly 30 to the two exterior facade structures 10 and two exterior roof structures 20 of a membrane building. The roof truss structure 25 is supported at both ends by facade beams 11. The area below the facade beams 11 forms facade ventilation openings 6. Symmetrical arch frames 22 are installed on the roof truss structure 25, thus forming two ridge ventilation openings 8. When both facade ventilation openings 6 and the two ridge ventilation openings 8 are open, a large-scale air convection can be formed inside and outside the membrane building. It should be noted that when the inflatable extrusion assembly 30 is applied to the arch frame 22, its tie rods 42 can be made of spring steel bars to better conform to the arc-shaped contour of the arch frame 22.

[0043] It should be noted that, Figure 12 and Figure 13The illustration shows the application scenario of the inflatable extrusion assembly 30 on the ventilation opening 5 of a single-span membrane building. The inflatable extrusion assembly 30 can also be applied to the ventilation opening 5 of a multi-span membrane building, for example, to the ventilation opening of a multi-span film greenhouse.

[0044] It should also be noted that when the movable membrane material 3 is a type of bulky thermal insulation roll (such as polyethylene foam roll), and is arranged on the outside of the membrane building envelope for thermal insulation or to remove thermal insulation of the membrane building envelope, the inflatable extrusion assembly 30 provided by the present invention can still be used to inflate and extrude the movable membrane material 30 of the bulky thermal insulation roll for protection or to release the inflatable extrusion to allow it to roll up.

[0045] like Figure 14 The diagram shows a plan view of the application of the inflatable extrusion assembly 30 on the membrane building facade structure 10, illustrating the facade structure 10 in a sealed state. Multiple facade columns 12 are connected at intervals to the lower side of the facade beam 11. A single movable membrane 3 is fully unfolded and hangs down, partially overlapping with the lower fixed membrane 2. The upper edge of the movable membrane 3 is fixedly connected to the membrane fixing connector 15, and the lower edge is connected to the roller rod 4. The roller rod 4 has completely released the movable membrane 3, exposing its rod body. The upper edge of the facade ventilation opening 6 is located near the facade beam 11, and the lower edge extends to the upper end of the fixed membrane 2. The upper ends of two tie rods 42 are connected to form a U-shaped structure and suspended on the tie rod connecting arm 13. Their lower ends are separated and respectively connected to the corresponding tie rod fastening seats 14 for tensioning.

[0046] like Figure 15 The diagram shows a plan view of the application of the inflatable extrusion assembly 30 on the membrane building facade structure 10, illustrating the facade structure 10 in an unsealed state (i.e., a ventilated state). At this time, the middle part of the roller 4 is wrapped with the movable membrane material 3, with its end exposed, so that external force can be applied to rotate the roller for operation.

[0047] The inflatable extrusion assembly of this invention and its application method on the exterior facade or roof structure of a greenhouse achieves rapid and reliable switching between the compression state through dynamic control of inflation and deflation. When inflated, it provides strong and uniform frontal pressure, ensuring the stability of the movable membrane material and the roll rod in windy weather. When deflated, it instantly releases pressure, minimizing the resistance to roll rod rotation and making operation easy. This completely overcomes the inherent defects of traditional membrane-pressing ropes, which are difficult to rotate when compressed and have poor wind resistance when loose, due to the difficulty in achieving a balance between tightness and looseness. Furthermore, the extrusion assembly can be arranged along the entire length of the steel structure to form a continuous and uniform compression force, solving the problem of discrete compression in traditional membrane-pressing ropes. The uneven pressure caused by this invention allows it to be reliably applied to large ventilation openings with a height of over 9 meters, a width of over 4 meters, and a length of over 100 meters, breaking through the technical bottleneck of traditional methods in the application of large-scale membrane buildings. At the same time, this invention makes it possible to enlarge the vertical height of facade ventilation openings or roof ventilation openings to almost the same height as the facade. This design of maximizing ventilation openings ensures extremely smooth air convection inside and outside the greenhouse, effectively eliminating the hot air accumulated inside, and reducing the maximum indoor temperature in summer to basically the same as the outdoor natural environment. This fundamentally solves the problem of high temperature and stuffiness in greenhouses caused by the forced reduction of ventilation openings due to fear of wind disasters.

[0048] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention.
