Description

Technical Field

[0001] This invention relates to the field of air-supported membrane architecture, and more specifically, to an anchoring structure for PVDF (polyvinylidene difluoride) membrane materials in high-altitude, hot, dry valleys with strong winds. Background Technology

[0002] Air-supported membrane structures refer to a building structure system that uses special architectural membrane materials as the outer shell or roof, and is equipped with an intelligent electromechanical system that provides positive air pressure inside the structure to support the main body. Air-supported membrane structures are characterized by their large span and flexibility, and can be custom-made for large-scale buildings such as airports, airport terminals, industrial plants, and warehouses.

[0003] High-altitude, hot, dry valleys with strong winds are characterized by complex and variable wind fields due to the influence of local winds such as canyon winds and foehn winds. Therefore, the construction of air-supported membrane structures in high-altitude, hot, dry valleys with strong winds places higher demands on the sealing performance of the membrane roof and the anchoring connection to the foundation. Summary of the Invention

[0004] This invention discloses a membrane anchoring structure for high-altitude, hot, dry valleys with strong winds. Specifically, this invention improves the anchoring foundation to form an anchoring structure with better sealing with the membrane roof, thereby solving the technical problem of poor sealing at the connection between the edge of the membrane roof and the concrete anchoring in air-supported membrane structures.

[0005] To solve the above problems, the present invention adopts the following technical solution:

[0018] In some embodiments, the PVDF membrane anchoring structure also includes a cap nut, which is threadedly engaged with one end of the screw that passes through the anchoring plate.

[0019] In some embodiments, the PVDF membrane anchoring structure further includes a limiting plate and adjusting nuts disposed on opposite sides of the limiting plate. The limiting plate is disposed on the screw rod and is movable relative to the screw rod along its axial direction. The adjusting nuts are threadedly engaged with the screw rod. The limiting plate can be abutted by at least one adjusting nut, and the limiting plate can move along the screw rod and abut against the reinforcing steel frame under the action of the adjusting nut.

[0020] In some embodiments, the PVDF membrane anchoring structure further includes a sealing gasket. The sealing gasket is disposed on the first surface, and both sides of the sealing gasket in the width direction extend beyond the first surface and are in contact with the surface of the concrete filler. When the PVDF membrane anchoring structure is fixedly connected to the edge of the membrane roof, the sealing gasket is located between the membrane roof and the first mounting plate.

[0021] In some embodiments, the PVDF membrane anchoring structure includes fasteners for connecting the membrane cables. The anchoring base includes a first base and a second base. The second base is located on the side of the first base away from the interior of the air-supported membrane structure, and the height of the second base is less than the height of the first base. A mounting seat is disposed on the first base. Fasteners are disposed on the second base. A waterproof curtain is provided at the edge of the membrane canopy. The waterproof curtain covers the mounting seat and extends to the sidewall of the first base. The membrane cables are pressed against the surface of the waterproof curtain.

[0022] In some embodiments, the upper surface of the second base portion has multiple second protrusions. The second protrusions are arranged sequentially at intervals along the extending direction of the second base portion. Each second protrusion corresponds to a fastener.

[0027] In some embodiments, the upper surface of the first extension portion is flush with the second base portion.

[0028] In some embodiments, a flow interruption groove is provided on the lower surface of the first extension portion. The flow interruption groove is located adjacent to the side of the first extension portion away from the second base portion.

[0029] In some embodiments, the anchoring foundation further includes a retaining wall portion. The retaining wall portion is vertically disposed below the first foundation portion and the second foundation portion.

[0030] In some embodiments, the PVDF membrane anchoring structure also includes a galvanized copper cable. One end of the galvanized copper cable is connected to a screw, and the other end is connected to the membrane cable.

[0031] The technical solution adopted in this invention can achieve the following beneficial effects:

[0032] In the PVDF membrane anchoring structure for high-altitude, hot, dry valleys with strong winds provided in this application, the mounting plate is embedded in the concrete filler of the anchoring foundation, and the first surface of the first mounting plate is exposed for installing and fixing the edge of the membrane roof. This embodiment is beneficial to ensuring the flatness of the surface where the membrane roof edge is installed, thereby improving the sealing performance between the membrane roof edge and the anchoring foundation. The first mounting plate of the mounting base is embedded in the anchoring foundation, which on the one hand improves the reliability of the assembly between the mounting base and the anchoring foundation, and on the other hand, the concrete filler can be used to provide support for the mounting base, which helps to prevent the mounting base from deforming under stress. In addition, the screw passes through the first mounting plate, and the spacing between two adjacent screws can be constrained by controlling the spacing between the holes on the first mounting plate for the screw to pass through. Furthermore, the opening direction of the hole can be used to constrain the extension direction of the screw, thereby improving the installation accuracy of the screw and enabling the screw to better fit the mounting holes opened at the edge of the membrane roof.

[0043] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0044] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0045] The following is in conjunction with the appendix Figures 1 to 8 The present application provides a detailed description of the PVDF membrane anchoring structure for high-altitude, hot, dry valleys and windy areas through specific embodiments and application scenarios.

[0046] Reference Figure 1 and Figure 2 This application provides a PVDF membrane anchoring structure for high-altitude, hot, dry valleys with strong winds, which can be used for fixing and sealing the edge of the membrane roof 100 in air-supported structures.

[0047] Reference Figure 2 The PVDF membrane anchoring structure provided in this application includes an anchoring base 200, a mounting base 300, a bolt 400, and an anchoring plate 500. The anchoring base 200 is a basic structure that provides an installation foundation for other components.

[0048] Reference Figure 2 In some embodiments, the anchoring foundation 200 includes a reinforcing steel frame 210 and concrete filler 220. The concrete filler 220 is poured onto the reinforcing steel frame 210. Specifically, the specific structure of the reinforcing steel frame 210 can refer to the structure of concrete foundations for air-supported membrane structures in the prior art. Therefore, this embodiment does not limit the specific structure of the reinforcing steel frame 210.

[0049] Reference Figure 2 The mounting base 300 is embedded in the concrete filler 220 and connected to the reinforcing steel cage 210. (Refer to...) Figure 2 and Figure 6 The mounting base 300 has a first mounting plate 310. A first surface 311 on one side of the first mounting plate 310 in the thickness direction is flush with and exposed on the surface of the concrete filler 220. For example, the thickness direction of the first mounting plate 310 can be... Figure 2 The direction indicated by the y-axis.

[0050] The first surface 311 is flush with the surface of the concrete filler 220, meaning that no step is formed between the edge of the first surface 311 and the surface of the concrete filler 220 to which it is joined.

[0051] In some embodiments, reference is made to Figure 2 The anchor plate 500 overlaps with the first mounting plate 310. The anchor plate 500 and the first mounting plate 310 are used to clamp the two sides of the edge of the membrane roof 100. One end of the screw 400 is perpendicular to the first surface 311, passes through the first mounting plate 310 and is embedded in the concrete filler 220, and the other end of the screw 400 passes through the membrane roof 100 and the anchor plate 500 in sequence and is connected to the anchor plate 500.

[0052] For example, the first mounting plate 310 is a steel plate.

[0053] In related technologies, the connecting bolts in the anchoring structure used to fix the edge of the membrane roof are embedded in the concrete foundation at intervals. During the installation of the bolts, each bolt needs to be positioned to ensure that the distance between two adjacent bolts is equal to the distance between two adjacent mounting holes on the edge of the membrane roof. In addition, the posture of each bolt needs to be corrected to ensure that adjacent bolts are parallel to each other.

[0054] In the solution provided in this application, the opening in the first mounting plate 310 of the mounting base 300 can facilitate the installation and positioning of the screw 400 and help maintain the parallel posture of the screws 400, thereby simplifying the positioning and installation of the screws 400 and the anchoring foundation 200. In addition, the first mounting plate 310 directly forms an anchoring plane. Compared with the surface formed by concrete, the first mounting plate 310 can form a flatter plane, which is beneficial to the sealing fit between the edge of the membrane roof 100 and the first mounting plate 310, and improves the sealing performance between the edge of the membrane roof 100 and the anchoring foundation 200.

[0055] Reference Figure 2 In some embodiments, the mounting base 300 further includes a second mounting plate 320 perpendicularly connected to the first mounting plate 310. The mounting base 300 is connected to the reinforcing steel frame 210 via the second mounting plate 320, and the second mounting plate 320 is at least partially embedded in the concrete filler 220.

[0056] In the above embodiment, the second mounting plate 320 is perpendicularly connected to the first mounting plate 310 and embedded within the concrete filler 220. Thus, the second mounting plate 320 can provide the first mounting plate 310 with... Figure 2 The forces acting in the x-axis, y-axis, and opposite directions of the x-axis improve the reliability of the assembly between the mounting base 300 and the anchoring foundation 200. For example, Figure 2 In this system, the x-axis and y-axis are two mutually perpendicular coordinate axes.

[0057] In some embodiments, the mounting base 300 is an angle steel plate. Specifically, the mounting base 300 is a galvanized angle steel plate. Exemplarily, the second mounting plate 320 is completely embedded within the concrete filler 220, which on the one hand protects the second mounting plate 320 from corrosion; on the other hand, it also forms a seal within the concrete filler 220, which helps prevent or reduce leakage of rainwater or gas along the gap between the first mounting plate 310 and the concrete filler 220.

[0058] Reference Figure 1 and Figure 2 The second mounting plate 320 is connected to the side of the first mounting plate 310 adjacent to the exterior of the air-supported membrane structure. For example, Figure 2The x-axis indicates the direction from the outside of the air-supported membrane structure to the inside. (See reference...) Figure 2 The first mounting plate 310 is embedded relatively shallowly into the concrete filler 220. During installation, the joint between the first mounting plate 310 and the concrete filler 220 may separate due to external impact, creating a gap. The second mounting plate 320 is positioned perpendicular to the first mounting plate 310, allowing it to embed deeper into the concrete filler 220. Even if the mounting base 300 is impacted, the joint between the second mounting plate 320 and the concrete filler 220 will not completely separate. Therefore, the second mounting plate 320 is connected to the side of the first mounting plate 310 adjacent to the exterior of the air-supported membrane structure, thus preventing external rainwater from seeping into the interior.

[0059] Reference Figure 2 and Figure 4 The concrete filler 220 covers the reinforcing steel frame 210, and the concrete filler 220 forms a first protrusion 221. A first mounting plate 310 is embedded in the first protrusion 221, and the first surface 311 is flush with the top of the first protrusion 221. This embodiment is beneficial in preventing rainwater from the outside of the air-supported membrane structure from flowing into the air-supported membrane structure along the surface of the concrete filler 220. In addition, this embodiment is also beneficial in preventing rainwater from the air-supported membrane structure from reaching the mounting base 300, thereby preventing the mounting base 300 from being corroded. Furthermore, this embodiment is also beneficial in improving the airtightness of the air-supported membrane structure.

[0060] In some optional embodiments, the second mounting plate 320 has a clearance groove 321 for avoiding the first reinforcing bar 211 in the reinforcing bar cage 210 that intersects with the second mounting plate 320. Exemplarily, the extending direction of the first reinforcing bar 211 intersects the extending direction of the second mounting plate 320. Specifically, the extending direction of the second mounting plate 320 is perpendicular to the extending direction of the first reinforcing bar 211.

[0061] In the above embodiment, the second mounting plate 320, by providing a clearance groove 321, facilitates the avoidance of reinforcing bars in the reinforcing bar cage 210 that intersect with the second mounting plate 320. Furthermore, the clearance groove 321 allows the second mounting plate 320 to form a stop and limit with the reinforcing bar cage 210 in the extending direction of the second mounting plate 320, which helps improve the reliability of the connection between the second mounting plate 320 and the anchoring foundation 200.

[0062] For example, the clearance groove 321 can be a notch provided on the second mounting plate 320 or a through hole provided on the second mounting plate 320.

[0063] In some embodiments, the second mounting plate 320 is welded to the reinforcing bar cage 210. For example, the second mounting plate 320 may be welded to and fixed to the first reinforcing bar 211.

[0064] In some embodiments, the anchor plate 500 includes a first sub-plate 510 and a second sub-plate 520. The first sub-plate 510 and the first mounting plate 310 overlap, and the edge of the second sub-plate 520 is connected to the side of the first sub-plate 510 near the interior of the air-supported structure. Exemplarily, the junction of the first sub-plate 510 and the second sub-plate 520 forms an arc-shaped edge. Specifically, the anchor plate 500 is an angle steel plate.

[0065] In the above embodiment, the second sub-plate 520 is beneficial for stopping the edge of the membrane roof 100 and preventing the edge of the membrane roof 100 from scratching with the screw 400.

[0066] In some embodiments, the surface of the concrete filler 220 adjacent to the first mounting plate 310 is inclined downwards along the direction from the interior to the exterior of the air-supported membrane structure. Specifically, the direction from the interior to the exterior of the air-supported membrane structure can be... Figure 2 The opposite direction indicated by the x-axis. The surface of the concrete filler 220 adjacent to the first mounting plate 310 is the upper surface of the concrete filler 220. The above embodiment is beneficial in preventing rainwater from flowing into the room along the upper surface of the concrete filler 220, and further beneficial in preventing rainwater from seeping into the interior of the air-supported structure through the assembly gaps of the various components of the PVDF membrane anchoring structure.

[0067] In some embodiments, the screw 400 and the first mounting plate 310 are mutually restrictive in the extension direction of the screw 400. For example, the screw 400 may be threaded into the first mounting plate 310. This embodiment utilizes the restrictive engagement between the screw 400 and the first mounting plate 310 to control the height of the screw 400 protruding from the first surface 311, thereby helping to prevent the screw 400 from protruding too much from the first surface 311 and affecting the installation of the membrane roof 100.

[0068] In some embodiments, the screw 400 can be connected to the membrane roof 100 and the anchor plate 500 via a nut. This embodiment helps prevent the screw 400 from being too long and forming sharp edges or points, helps prevent the screw 400 from scratching the edge of the membrane roof 100, and thus helps protect the edge portion of the membrane roof 100.

[0069] In some embodiments, the end of the screw 400 that protrudes from the first surface 311 does not protrude from the side of the nut away from the anchor plate 500.

[0070] In some embodiments, reference is made to Figure 2 and Figure 7 The PVDF membrane anchoring structure also includes a cap nut 600, which is threadedly engaged with one end of the screw 400 that passes through the anchoring plate 500. Specifically, the end of the cap nut 600 is spherical, which helps to avoid scratching the edges of the membrane canopy 100.

[0071] In some embodiments, reference is made to Figure 6 and Figure 7 The screw 400 has a first threaded section 410, a second threaded section 420, and a limiting section 430 disposed between the first threaded section 410 and the second threaded section 420. The first threaded section 410 passes through the first mounting plate 310 and is threadedly engaged with the first mounting plate 310. The radial dimension of the limiting section 430 is larger than the radial dimension of the first threaded section 410, and the limiting section 430 abuts against a second surface 312 in the first mounting plate 310 opposite to the first surface 311. The second threaded section 420 is located within the concrete filler 220 and is connected to the reinforcing steel cage 210.

[0072] Specifically, the dimensions of the first threaded section 410 in the screw 400 can be customized as needed. During the installation of the screw 400, simply abutting the limiting section 430 against the second surface 312 can prevent the portion of the screw 400 protruding from the first surface 311 from being too long or too short, thereby simplifying the installation of the screw 400.

[0073] In some embodiments, the limiting segment 430 may be, but is not limited to, prism or cylindrical. In alternative embodiments, the limiting segment 430 is formed on a hexagonal prism axial step between the first threaded segment 410 and the second threaded segment 420 to facilitate the assembly of the screw 400 onto the mounting base 300.

[0074] Reference Figures 4 to 6 In some embodiments, the PVDF membrane anchoring structure further includes a limiting plate 700 and adjusting nuts 800 disposed on opposite sides of the limiting plate 700. The limiting plate 700 is disposed on the screw 400 and is movable relative to the screw 400 along the axial direction of the screw 400. The adjusting nuts 800 are threadedly engaged with the screw 400, and the limiting plate 700 can be abutted against at least one adjusting nut 800. The limiting plate 700 can move along the screw 400 under the action of the adjusting nuts 800 and abut against the reinforcing steel frame 210.

[0075] In the above embodiment, the mounting base 300 can be adjusted by the limiting plate 700 to prevent excessive bending deformation of the mounting base 300 from affecting the parallelism of two adjacent screws 400. It should be noted that after the mounting base 300 is bent, the parallelism between two adjacent screws 400 at the bent part will be poor. This will cause the distance between some screws 400 to be greater or less than the distance between the reserved holes at the edge of the membrane roof 100, thereby increasing the installation difficulty and affecting the sealing performance of the edge of the membrane roof 100.

[0076] For example, refer to Figure 4When the mounting base 300 bends downwards, the limiting plate 700 can stop it from hitting the top of a certain steel bar in the steel reinforcement cage 210, and the adjusting nut 800 can be rotated to allow the screw 400 to support the mounting base 300 to return to its original deformation. (Refer to...) Figure 5 When the mounting base 300 bends upward, it can be stopped by the limiting plate 700 against the bottom of a certain steel bar in the steel reinforcement cage 210, and the screw 400 can be pulled downward to restore the deformation by rotating the adjusting nut 800.

[0077] In addition, the limiting plate 700 and the adjusting nut 800 can also provide the screw 400 with a force along its extension direction, which is beneficial to improving the reliability of the screw 400 and the concrete filler 220.

[0078] Reference Figure 6 or Figure 7 In some embodiments, only a portion of the screw 400 is provided with a limit plate 700 and an adjusting nut 800. Specifically, the limit plate 700 and the adjusting nut 800 can be installed at corresponding positions according to the actual situation.

[0079] In some embodiments, reference is made to Figure 2 The PVDF membrane anchoring structure also includes a sealing gasket 900. The sealing gasket 900 is disposed on the first surface 311, and both sides of the sealing gasket 900 in the width direction extend beyond the first surface 311 and adhere to the surface of the concrete filler 220. For example, the width direction of the sealing gasket 900 is... Figure 2 The direction indicated by the x-axis. With the PVDF membrane anchoring structure fixedly connected to the edge of the membrane canopy 100, the sealing gasket 900 is located between the membrane canopy 100 and the first mounting plate 310.

[0080] For example, the sealing gasket 900 can be, but is not limited to, a rubber gasket.

[0081] In the above embodiments, the sealing gasket 900 is beneficial to improving the sealing performance of the PVDF membrane anchoring structure and the edge portion of the membrane roof 100. Furthermore, the fact that both sides of the sealing gasket 900 extend beyond the first surface 311 and adhere to the surface of the concrete filler 220 in the width direction also helps prevent rainwater from entering the joint between the mounting base 300 and the concrete filler 220, thereby improving the sealing performance of the PVDF membrane anchoring structure and the edge portion of the membrane roof 100.

[0082] In some embodiments, the surface of the first boss 221 that joins with the first surface 311 is an inclined surface. For example, along the direction from the interior to the exterior of the air-supported structure, the surface of the first boss 221 that joins with the first surface 311 on the side away from the interior of the air-supported structure slopes downwards. Along the direction from the exterior to the interior of the air-supported structure, the surface of the first boss 221 that joins with the first surface 311 on the side closer to the interior of the air-supported structure slopes downwards. Specifically, both sides of the sealing gasket 900 extend into the inclined surface where the first boss 221 joins with the first surface 311 in the width direction.

[0083] In the above embodiment, the sealing gasket 900 and the first protrusion 221 can be fitted together to prevent rainwater from seeping towards the mounting base 300, and the inclined surface formed by the first protrusion 221 can also be used to hinder rainwater from seeping towards the mounting base 300. Therefore, this embodiment is beneficial in preventing rainwater from leaking into the air-supported structure and also in preventing rainwater from corroding the mounting base 300.

[0084] Reference Figure 2 and Figure 3 In some embodiments, a waterproof curtain 110 is provided at the edge of the membrane canopy 100. The waterproof curtain 110 covers the mounting base 300. In this embodiment, the waterproof curtain 110 can completely cover the mounting base 300, the screw 400, and the anchor plate 500, thereby helping to prevent the mounting base 300, the screw 400, and the anchor plate 500 from being exposed, and thus helping to slow down or prevent corrosion of the mounting base 300, the screw 400, and the anchor plate 500. In addition, it also helps to prevent damage to the protective coating of the mounting base 300, the screw 400, and the anchor plate 500.

[0085] In some embodiments, the PVDF membrane anchoring structure includes a fastener 1100 for connecting the membrane cable 1000. The anchoring base 200 includes a first base portion 230 and a second base portion 240. Exemplarily, the first base portion 230 and the second base portion 240 are an integral structure. The second base portion 240 is located on the side of the first base portion 230 away from the interior of the air-supported membrane structure, and the height of the second base portion 240 is less than the height of the first base portion 230. A mounting base 300 is disposed on the first base portion 230. The fastener 110 is disposed on the second base portion 240. A waterproof curtain 110 covers the mounting base 300 and extends to the sidewall of the first base portion 230. Specifically, the waterproof curtain 110 extends to the sidewall of the second base portion 240 away from the first base portion 230.

[0086] In the above embodiment, the height of the second base portion 240 is less than the height of the first base portion 230. The step formed between the first base portion 230 and the second base portion 240 can be used to block external rainwater from flowing into the interior of the air-supported membrane structure. In addition, the waterproof curtain 110 covers the mounting base 300 and extends to the side wall of the first base portion 230, which can guide rainwater on the air-supported membrane to the second base portion 240, which helps to prevent rainwater from flowing back into the mounting base 300, thereby protecting the mounting base 300 and preventing rainwater from entering the interior.

[0087] In some embodiments, reference is made to Figure 2 and Figure 3 The membrane cable 1000 presses against the surface of the waterproof curtain 110. This embodiment uses the membrane cable 1000 to limit the waterproof curtain 110, preventing it from folding over. Furthermore, during routine inspection and maintenance of the air-supported structure, the membrane cable 1000 can be adjusted to fold over the waterproof curtain 110, exposing components such as the mounting base 300, cap nut 600, anchor plate 500, and screw 400, thus facilitating routine inspection and maintenance of the air-supported structure.

[0088] In some optional embodiments, the waterproof curtain 110 may also be provided with a fixing strip. For example, the waterproof curtain 110 can be fixed to the membrane cable 1000 by the fixing strip. For example, the fixing strip can be a Velcro strap or a binding rope.

[0089] Reference Figure 2 and Figure 8 In some embodiments, the edge of the first base portion 230 adjacent to the second base portion 240 is arc-shaped. Exemplarily, the membrane cable 1000 and the waterproof curtain 110 form a bent portion under the support of the edge of the first base portion 230. Optionally, a protective sleeve 1010 is fitted onto the bent portion of the membrane cable 1000. Exemplarily, the protective sleeve 1010 can be, but is not limited to, a rubber sleeve. This embodiment is beneficial in improving the fixing effect of the membrane cable 1000 on the waterproof curtain 110 and in preventing the waterproof curtain 110 from folding over.

[0090] In some embodiments, reference is made to Figure 4 and Figure 5 The upper surface of the second base portion 240 has a plurality of second protrusions 241. Along the extension direction of the second base portion 240, the second protrusions 241 are arranged sequentially at intervals, and each second protrusion 241 corresponds to a fastener 1100. The fastener 1100 passes through the second protrusion 241 and is connected to the steel reinforcement frame 210.

[0091] Specifically, rainwater flowing down from the membrane roof 100 can flow directly from between two adjacent second protrusions 241 in a direction away from the first base 230, which helps prevent rainwater from seeping through the gap between the fastener 1100 and the concrete filler 220 and helps slow down the corrosion of the fastener 1100.

[0092] In some embodiments, the upper surface of the first base 230 is inclined downwards along the direction from the interior to the exterior of the air-supported structure. This embodiment facilitates rainwater leakage along the first base 230 towards the exterior. This embodiment also helps to keep the surface of the first base 230 dry.

[0093] In some embodiments, the upper surface of the second base 240 is inclined downwards along the direction from the interior to the exterior of the air-supported structure. This embodiment facilitates rainwater leakage along the second base 240 towards the exterior. This embodiment also helps to keep the surface of the second base 240 dry.

[0094] In some embodiments, reference is made to Figures 3 to 5 The anchoring foundation 200 also includes a first extension portion 250. The first extension portion 250 is disposed on the side wall of the second foundation portion 240 away from the first foundation portion 230, and the upper surface of the first extension portion 250 is inclined downward along the direction from the interior of the air-supported membrane building to the exterior of the air-supported membrane building.

[0095] For example, the area below the first extension portion 250 can be used for installing cables and / or conduits.

[0096] In the above embodiments, it is beneficial to prevent rainwater from flowing down the side wall of the anchor foundation 200 and to keep the facade of the anchor foundation 200 dry.

[0097] In some embodiments, the anchoring foundation 200 further includes a second extension portion 260 disposed on the side wall of the first foundation portion 230 away from the second foundation portion 240.

[0098] For example, the area below the second extension 260 can be used to install cables and / or conduits.

[0099] Reference Figures 3 to 5 In some embodiments, the upper surface of the first extension portion 250 is flush with the second base portion 240.

[0100] Reference Figures 3 to 5 A flow-blocking groove 251 is provided on the lower surface of the first extension portion 250. The flow-blocking groove 251 is provided adjacent to the side of the first extension portion 250 away from the second base portion 240. The flow-blocking groove 251 helps to prevent rainwater from flowing along the lower surface of the first extension portion 250 towards the interior.

[0101] In some embodiments, a flow interruption groove 251 is provided on the lower surface of the second extension portion 260. The flow interruption groove 251 is provided adjacent to the side of the second extension portion 260 away from the first base portion 230.

[0102] In some embodiments, reference is made to Figure 3 The anchoring foundation 200 also includes a retaining wall portion 270, which is vertically disposed below the first foundation portion 230 and the second foundation portion 240. For example, the height of the retaining wall portion 270 ranges from 1m to 3m. It should be noted that... Figure 3 The steel reinforcement cage within the retaining wall section 270 is not shown in the diagram. Specifically, the structure, quantity, and type of steel reinforcement within the retaining wall section 270 can be adjusted according to the actual stress conditions of the retaining wall section 270 in the air-supported structure. Therefore, this embodiment does not limit the specific structure of the steel reinforcement cage within the retaining wall section 270.

[0103] The above embodiments help reduce the vertical height of the membrane roof 100, making the top surface of the membrane roof 100 flatter, which in turn helps reduce the swaying of the membrane roof 100 under wind force. In addition, the setting of the retaining wall 270 can also avoid the formation of narrow spaces at the internal edges of the air-supported membrane structure, which helps to improve space utilization.

[0104] Reference Figure 2 In some embodiments, the PVDF membrane anchoring structure further includes a galvanized copper cable 1200. One end of the galvanized copper cable 1200 is connected to the screw 400, and the other end is connected to the membrane cable 1000. Exemplarily, one end of the galvanized copper cable 1200 is provided with a connector 1210. Exemplarily, the connector 1210 can be a perforated metal sheet. Exemplarily, the connector 1210 is sleeved on the screw 400, and the galvanized copper cable 1200 is fastened to the connector 1210 by bolts. Specifically, the connector 1210 is located between the cap nut 600 and the anchoring plate 500. This embodiment is beneficial for achieving electrical connection between the anchoring plate 500 and the membrane cable 1000, and is beneficial for improving the lightning protection effect of the air-supported membrane structure. It should be noted that, in order to improve the corrosion resistance of the membrane cable 1000, the surface of the membrane cable 1000 and / or the surface of the fixing member 1100 are covered with an insulating protective layer. Therefore, the anchor plate 500 and the membrane cable 1000 can be electrically connected, which is beneficial for connecting to the ground through the screw 400 and the steel reinforcement frame 210. In addition, the galvanized copper cable 1200 is also beneficial for improving the reliability of the membrane cable 1000 and reducing the sway of the membrane cable 1000.

[0105] In some embodiments, the protective sleeve 1010 covers the portion where the galvanized copper cable 1200 connects to the membrane cable 1000. Exemplarily, the membrane cable 1000 is a steel cable with an external insulating and waterproof rubber layer. The galvanized copper cable 1200 is electrically connected to the steel cable inside the membrane cable 1000. The protective sleeve 1010 covers the portion where the galvanized copper cable 1200 connects to the membrane cable 1000 and provides a sealed connection with the external rubber layer of the membrane cable 1000. Specifically, the sealed connection between the protective sleeve 1010 and the external rubber layer of the membrane cable 1000 can be achieved by, but is not limited to, adhesive bonding, hot-melt welding, etc.

[0106] Reference Figure 8 In some embodiments, the edge of the membrane roof 100 is further provided with an edge rope 120. Exemplarily, the edge of the membrane roof 100 is folded over to wrap around the edge rope 120, forming a double-layer structure. Specifically, the edge rope 120 is located adjacent to the side of the first sub-plate 510 of the anchor plate 500 away from the interior of the air-supported membrane structure. Exemplarily, the edge rope 120 can create a thicker edge at the folded position of the membrane roof 100, which helps prevent the edge of the membrane roof 100 from sliding relative to the anchor plate 500 and the mounting base 300, thereby improving the reliability of the edge fixation of the membrane roof 100 and the continuity and integrity of the edge of the membrane roof 100 held by the anchor plate 500 and the mounting base 300.

[0107] In some embodiments, reference is made to Figure 2 and Figure 8 The width of the folded edge curtain formed after the edge of the membrane roof 100 is folded up is greater than the width of the anchor plate 500 and the mounting base 300, and the folded edge curtain extends towards the interior side of the air-supported membrane structure and covers the first protrusion 221. This embodiment is beneficial for protecting the anchor plate 500 and the mounting base 300.
