Description

Technical Field

[0001] This application relates to the field of cable adjustment, specifically to an inflatable membrane steel cable adjustment device. Background Technology

[0002] During the installation and construction of inflatable membrane structures, cable nets are needed to stabilize the surface of the membrane. Typically, the cable nets are first installed on the underlying civil engineering structure according to the design, and then the membrane is pressurized and shaped. However, in some cases, due to the complex and varied conditions of the installation site, the cable net structure cannot be installed on all civil engineering structures at once.

[0003] Traditionally, the method involves directly tensioning the cable and connecting it to the civil structure. However, during tensioning, the force acts directly on the cable, making its protective surface layer highly susceptible to damage. Once this protective layer is damaged, the cable itself comes into contact with the external environment, making it prone to oxidation or corrosion. This significantly impacts the cable's lifespan and aesthetics. Furthermore, directly tensioning the cable requires multiple steps during installation, including disassembly and reassembly, making the process quite complex. Utility Model Content

[0004] This application addresses the aforementioned shortcomings of the prior art by providing an inflatable membrane cable adjustment device to solve at least one of the above-mentioned technical problems. The specific structure is as follows:

[0005] An inflatable membrane steel cable adjustment device is used to adjust the position and direction of the connecting cable on the surface of the inflatable membrane. Specifically, it includes the connecting cable, the traction mechanism, and the base layer pre-embedded structure.

[0006] The base layer embedded structure is located on the installation surface of the inflatable membrane, and at least one embedded part is protruding from the base layer embedded structure;

[0007] At least one end of the connecting cable is provided with a snap-fit ​​structure; one end of at least one traction mechanism is connected to the connecting cable, and the other end of the traction mechanism is used to be externally tractioned to drive the connecting cable closer to the embedded part, and is detachably connected to one of the embedded parts through the snap-fit ​​structure.

[0008] In one specific embodiment, multiple connecting cables are arranged in a crisscross pattern, overlapping each other and spanning the surface of the inflatable membrane, forming a cable net system on the surface of the inflatable membrane to stabilize its shape.

[0009] In some specific embodiments, the connecting cable includes a steel cable with at least one protective layer covering its surface.

[0010] In some specific embodiments, there are multiple embedded parts, and each embedded part is separated by a preset distance; the embedded part includes a first embedded part and at least one second embedded part; the end of the traction mechanism away from the connecting cable passes through the first embedded part and at least one second embedded part in sequence; the buckle structure is detachably connected to the first embedded part.

[0011] In some specific embodiments, the traction mechanism includes a traction rope and a reinforcement component, wherein the traction rope is fixedly mounted on the connecting cable near the buckle structure by the reinforcement component.

[0012] In some specific embodiments, the reinforcement component includes at least one rope clamping mechanism, on which a fastening adjustment element is provided; the rope clamping mechanism is located on the connecting cable near the buckle structure, one end of the traction rope is fixed to the connecting cable through the rope clamping mechanism, and the fastening adjustment element is used to adjust the connection strength between the traction rope and the connecting cable.

[0013] In one specific embodiment, the fastening adjustment component can be a bolt structure. By adjusting the tightness of the bolt, one end of the traction rope can be fastened to the connecting cable, thus achieving a fixed connection between one end of the traction rope and the connecting cable. At the same time, the user can flexibly adjust the tightness of the fastening adjustment component according to the actual application.

[0014] In some specific embodiments, the reinforcement component includes a wire clamp; one end of the connecting cable passes through the fixed slot and is fixed in the fixed slot; the wire clamp includes a fixed block and a movable block that movably connects to the fixed block, the fixed block having a fixed slot and the movable block having a connecting hole;

[0015] One end of the traction rope has a movable knot that passes through a connecting hole, allowing the traction rope to be movably connected to the movable block.

[0016] In some specific embodiments, an external tensioning device and an adjusting mechanism are also included; the embedded part includes a connecting ring; at least one adjusting mechanism is provided on at least one connecting ring; the end of the traction rope away from the connecting cable passes through at least one adjusting mechanism and is connected to the external tensioning device through the adjusting mechanism;

[0017] The external tensioning device is used to stretch the traction rope. Specifically, it can stretch the traction rope toward the embedded part to bring the buckle structure of the connecting cable closer to the embedded part. Specifically, as long as the connection between the connecting cable and the embedded part can be achieved, the buckle structure can be directly connected to the connecting ring, or it can be indirectly connected to the connecting ring by connecting to the adjusting mechanism.

[0018] In some specific embodiments, the snap-fit ​​structure includes a heart-shaped buckle, the embedded part includes a connecting ring protruding relative to the base embedded structure, and the adjustment mechanism can be a shackle structure or a fixed pulley structure. In a specific application, the fixed pulley structure is set on the embedded part, one end of the traction rope is movably connected to the movable block of the wire clamp via a movable knot, and the other end passes through the fixed pulley structure and is connected to the external tensioning device. When the external tensioning device begins to apply tension to the traction rope, the tension in the traction rope drives the wire clamp to move, further pulling the connecting cable in the fixed slot of the wire clamp, so that the heart-shaped buckle on one end of the connecting cable gradually approaches the connecting ring on the base embedded structure, until the heart-shaped buckle and the connecting ring can be directly snapped together.

[0019] It should be noted that this application does not specifically limit the number of fixing components installed on each connecting cable or the number of traction ropes connected to each connecting cable. By setting traction ropes, the direction and point of force on the connecting cable can be changed during the installation process. The tension on the connecting cable that should be borne by the buckle structure is decomposed and the force is transferred to the embedded parts or adjustment mechanisms connected to the traction ropes, which can effectively reduce the stress on the ends of the connecting cables and the surface protective layer of the steel cable in the connecting cables.

[0020] In some specific embodiments, a limiting block is provided on the end of the traction rope that is connected to the reinforcement component. The limiting block is used to engage with the reinforcement component when the traction rope is pulled, so as to prevent the traction rope from coming out of the reinforcement component.

[0021] In some specific embodiments, the length of the traction mechanism is greater than the distance from the position of the traction mechanism on the connecting cable to the buckle structure. Specifically, the length of the traction rope may be greater than the distance from the reinforcing component on the connecting cable to the buckle structure.

[0022] In some specific embodiments, the pre-embedded structure of the base layer includes a retaining wall.

[0023] In practical applications, the density and number of embedded parts can be adjusted according to the stress distribution of the inflatable membrane structure. Multiple embedded parts can be evenly arranged on the retaining wall, or they can be arranged more densely in areas where the inflatable membrane is under greater stress than in other areas; the extension direction of the traction rope is parallel to the top surface of the retaining wall.

[0024] It should be noted that this application does not specifically limit the relative angle between the connecting cables and the retaining wall. In one specific embodiment, multiple connecting cables are arranged perpendicular to the plane where the top surface of the retaining wall is located, forming a crisscrossing cable net system on the surface of the inflatable membrane. This is suitable for scenarios where the load generated by the inflatable membrane is regularly distributed and can form a uniform stress system. Alternatively, multiple connecting cables can be inclined relative to the plane where the top surface of the retaining wall is located and intersect and overlap each other, forming acute or obtuse angles. This can form a triangular or rhomboid cable net system on the surface of the inflatable membrane, forming a bidirectional or tridirectional stress system. This allows the load on the connecting cables to be transmitted and dispersed in multiple directions, avoiding stress concentration.

[0025] In practical applications, the retaining wall is a concrete retaining wall used to fix the inflatable membrane, and the upper surface of the retaining wall is also equipped with metal fasteners for fixing the inflatable membrane.

[0026] In some specific embodiments, the protective layer includes a polyethylene protective layer, and / or a rubber protective layer, and / or a nylon protective layer. In practical applications, the steel cable contains steel bundles, and the outer surface of the steel cable is covered with a polyethylene protective layer, wherein the thickness of the polyethylene protective layer ranges from 1.5 to 2.0 mm. In practice, the thickness of the polyethylene protective layer on the surface of the steel cable varies depending on the specifications of the steel cable. For example, for conventional 16# and below steel cables, the polyethylene protective layer thickness is 1.5 mm; for 18# and above steel cables, the polyethylene protective layer thickness is 2.0 mm.

[0027] In one specific embodiment, depending on actual requirements, a partial protective sleeve may be further applied to the location on the connecting cable used for connection with the traction mechanism to reduce direct contact between the protective layer and the traction mechanism and extend the service life of the steel cable and the protective layer.

[0028] Beneficial effects: This application provides an inflatable membrane steel cable adjustment device, including a connecting cable, a traction mechanism, and a base layer pre-embedded structure; by setting a buckle structure on at least one end of the connecting cable; and by setting at least one end of the traction mechanism connected to the connecting cable, so that the other end of the traction mechanism is used to be externally tractioned to drive the connecting cable closer to the pre-embedded part, the force direction of the connecting cable can be changed, and the force of the connecting cable can be transferred through the traction mechanism, thereby adjusting the position of the connecting cable relative to the surface of the inflatable membrane and the direction of movement during installation. While traction is performed, the buckle structure of the connecting cable is not occupied, realizing a fast and efficient connection between the connecting cable and the pre-embedded part, which can effectively reduce the operation steps in the installation, improve the installation efficiency of the connecting cable, and achieve a stable installation of the inflatable membrane.

[0049] Example

[0050] This application provides an inflatable membrane steel cable adjustment device, the specific solution of which is as follows:

[0051] An inflatable membrane cable adjustment device is used to adjust the position and direction of the connecting cable 1 on the surface of the inflatable membrane 4. Specifically, it includes the connecting cable 1, a traction mechanism 2, and a base layer pre-embedded structure 3. The base layer pre-embedded structure 3 is located on the mounting surface of the inflatable membrane 4, and at least one pre-embedded part 31 protrudes from the base layer pre-embedded structure 3.

[0052] At least one end of the connecting cable 1 is provided with a snap-fit ​​structure 13; one end of at least one traction mechanism 2 is connected to the connecting cable 1, and the other end of the traction mechanism 2 is used to be externally tractioned to drive the connecting cable 1 closer to the embedded part 31, so that the connecting cable 1 passes through the surface of the inflatable membrane 4 and is detachably connected to one of the embedded parts 31 through the snap-fit ​​structure 13, as shown in the following figure. Figure 1 As shown.

[0053] In one specific embodiment, multiple connecting cables 1 cross and span the surface of the inflatable membrane 4, forming a net cable system on the surface of the inflatable membrane 4. This system can cover the surface of the inflatable membrane 4, stabilize the shape of the inflatable membrane 4, and prevent the inflatable membrane 4 from undergoing large deformation.

[0054] In some specific embodiments, the connecting cable 1 includes a steel cable 11, and the surface of the steel cable 11 is covered with at least one protective layer 12. Since the connecting cable 1 is a steel cable 11, the protective layer 12 on its surface can effectively prevent oxidation and corrosion of the steel cable 11, thereby extending the service life of the steel cable 11.

[0055] In some specific embodiments, there are multiple embedded parts 31, and each embedded part 31 is separated by a preset distance. The embedded part 31 includes a first embedded part 311 and at least one second embedded part 312.

[0056] The end of the traction mechanism 2 away from the connecting cable 1 passes sequentially through the first embedded part 311 and at least one second embedded part 312; the snap-fit ​​structure 13 is detachably connected to the first embedded part 311. Thus, the traction mechanism 2 can pull the connecting cable 1 toward the first embedded part 311, and finally achieve the connection between the connecting cable 1 and the first embedded part 311.

[0057] In some specific embodiments, the traction mechanism 2 includes a traction rope 21 and a reinforcing component 22. The traction rope 21 is fixedly mounted on the connecting cable 1 near the buckle structure 13 by the reinforcing component 22.

[0058] In practical applications, the first embedded part 311 and the second embedded part 312 are located on the same plane, that is, on the base embedded structure 3. By passing the traction rope 21 in the traction mechanism 2 through the first embedded part 311, the traction direction of the traction rope 21 on the connecting cable 1 can be positioned so that when the traction rope 21 is stretched outward, the connecting cable 1 can be moved towards the first embedded part 311. As the traction rope 21 stretches the connecting cable 1 further, the connecting cable 1 can move forward until it comes into contact with the embedded part 31. At this time, the stretching length of the connecting cable 1 meets the installation requirements, and the buckle structure 13 at one end of the connecting cable 1 can be connected to the embedded part 31. Specifically, the buckle structure 13 can be connected to the first embedded part 311 to realize the installation of the connecting cable 1.

[0059] In specific applications, by passing the traction rope 21 in the traction mechanism 2 through the first embedded part 311 and then further passing the traction rope 21 through at least one second embedded part 312, the tension of the traction rope 21 on the connecting cable 1 can be decomposed and transmitted outward. The tension is further decomposed into the first embedded part 311 and at least one second embedded part 312. Since the second embedded part 312 and the first embedded part 311 are on the same plane, in the actual stretching process, the first embedded part 311 and the second embedded part 312 can act like pulleys, stabilizing the stretching direction of the traction rope 21 and reducing the tension of the traction rope 21. It should be noted that this application does not specifically limit the specific shape of the first embedded part 311 and the second embedded part 312. As long as it can limit the stretching of the traction rope 21 and guide the stretching direction, the user can adjust the position and shape of the first embedded part 311 and the second embedded part 312 according to actual needs. In a specific embodiment, the first embedded part 311 and the second embedded part 312 may include a ring-shaped structure facing the stretching direction of the traction rope 21, such as... Figure 3 and Figure 4 As shown, it should be noted that this embodiment does not limit the setting direction of the ring structure. As long as the traction rope 21 can be pulled, the ring structure can be set with the opening facing the extension direction of the base embedded structure 3, or it can be set perpendicular to or inclined to the extension direction of the base embedded structure 3.

[0060] In one specific embodiment, the first embedded part 311 and the second embedded part 312 can also be an angle steel structure set at the edge of the air-supported membrane body for fixing the air-supported membrane, and a U-shaped shackle set on the angle steel structure, such as Figure 10 As shown in the side view, the U-shaped shackle is set on the angle steel structure. The traction rope 21 passes through the U-shaped shackles on the angle steel structure of the first embedded part 311 and the second embedded part 312 in sequence to further realize the traction of the connecting cable 1.

[0061] In some specific embodiments, such as Figure 2 and Figure 4 As shown, the reinforcement component 22 includes at least one rope clamping mechanism 222, and a fastening adjustment component 2221 is provided on the rope clamping mechanism 222. The rope clamping mechanism 222 is located on the connecting cable 1 near the buckle structure 13. One end of the traction rope 21 is fixed to the connecting cable 1 through the rope clamping mechanism 222. The fastening adjustment component 2221 is used to adjust the connection strength between the traction rope 21 and the connecting cable 1.

[0062] In one specific embodiment, the fastening adjustment component 2221 can be a bolt structure. By adjusting the tightness of the bolt, one end of the traction rope 21 can be fastened to the connecting cable 1, thereby achieving a fixed connection between one end of the traction rope 21 and the connecting cable 1. At the same time, the user can flexibly adjust the tightness of the fastening adjustment component 2221 according to the actual application.

[0063] In some specific embodiments, the reinforcement component 22 includes a wire clamp 221; one end of the connecting cable 1 passes through the fixed slot 2213 and is fixed in the fixed slot 2213; the wire clamp 221 includes a fixed block 2211 and a movable block 2212 that movably connects to the fixed block 2211, the fixed block 2211 is provided with a fixed slot 2213, and the movable block is provided with a connecting hole 2214;

[0064] One end of the traction rope 21 has a movable knot, which passes through the connecting hole 2214 so that the traction rope 21 can be movably connected to the movable locking block 2212.

[0065] In some specific embodiments, an external tensioning device and an adjusting mechanism 33 are also included; the embedded part 31 includes a connecting ring 32; at least one adjusting mechanism 33 is provided on at least one connecting ring 32; the end of the traction rope 21 away from the connecting cable 1 passes through at least one adjusting mechanism 33 and is connected to the external tensioning device through the adjusting mechanism 33.

[0066] The external tensioning device is used to tension the traction rope 21. Specifically, it can tension the traction rope 21 towards the embedded part 31, thereby causing the buckle structure 13 of the connecting cable 1 to move closer to the embedded part 31. Specifically, the buckle structure 13 can be directly connected to the connecting ring 32, or it can be indirectly connected to the connecting ring 32 by connecting to the adjusting mechanism 33.

[0067] In some specific embodiments, the snap-fit ​​structure 13 includes a heart-shaped buckle, the embedded part 31 includes a connecting ring 32 protruding relative to the base embedded structure 3, and the adjusting mechanism 33 can be a shackle structure or a fixed pulley structure fastened to the connecting ring 32, wherein the shackle structure is as follows: Figure 1 , Figure 2 as well as Figure 7 As shown, the fixed pulley structure is as follows: Figure 5As shown. In a specific application, the fixed pulley structure is set on the embedded part 31. One end of the traction rope 21 is movably connected to the movable locking block 2212 of the wire clamp 221 via a movable knot, and the other end passes through the fixed pulley structure and is connected to the external tensioning device. When the external tensioning device begins to apply tension to the traction rope 21, the tension in the traction rope 21 drives the wire clamp 221 to move, which further drives the connecting cable 1 in the fixed locking groove 2213 of the wire clamp 221 to be pulled, so that the heart-shaped buckle on one end of the connecting cable 1 gradually approaches the connecting ring 32 on the embedded structure 3 of the base layer, until the heart-shaped buckle and the connecting ring 32 can be directly interlocked. As can be seen, by using the traction mechanism 2 to pull the connecting cable 1, the position of the connecting cable 1 relative to the inflatable membrane 4 can be adjusted without occupying the buckle structure 13, thereby realizing the movement and stretching of the connecting cable 1. This allows the buckle structure 13 to be directly engaged with the connecting ring 32 after reaching the designated position, reducing the number of operation steps in the installation process and making the entire installation process more efficient and faster. At the same time, since the tension of the connecting cable 1 can be decomposed, the connecting cable 1 itself can also be better protected.

[0068] After the connecting loop 1 and the connecting ring 32 are fastened together, the connection between the traction rope 21, the connecting rope 1, and each embedded part 31 can be maintained to continue the traction on the connecting rope 1, distributing its tension to the multiple embedded parts 31; alternatively, the traction rope 21 can be removed, such as... Figure 6 As shown, the traction of connecting cable 1 is completed.

[0069] It should be noted that this application does not specifically limit the number of fixing components provided on each connecting cable 1 or the number of traction ropes 21 connected to each connecting cable 1. By providing traction ropes 21, the direction and point of force on the connecting cable 1 during installation can be changed, decomposing the tension on the connecting cable 1 that should be borne by the buckle structure 13, and transferring the force to the embedded part 31 or adjustment mechanism 33 connected to the traction rope 21, which can effectively reduce the stress on the end of the connecting cable 1 and the surface protective layer 12 of the steel cable 11 in the connecting cable 1.

[0070] In some specific embodiments, a limiting block 211 is provided on the end of the traction rope 21 that is connected to the reinforcing component 22. The limiting block 211 is used to engage with the reinforcing component 22 when the traction rope 21 is pulled, so as to prevent the traction rope 21 from coming out of the reinforcing component 22. By providing the limiting block 211 at the position where the traction rope 21 is fixedly connected to the connecting cable 1, the fixed connection between the traction rope 21 and the reinforcing component 22 can be further strengthened. This is suitable when the reinforcing component 22 includes a rope clamping mechanism, and can ensure that the external tensioning device can then stably stretch the traction rope 21.

[0071] In some specific embodiments, the length of the traction mechanism 2 is greater than the distance from the position of the traction mechanism 2 on the connecting cable 1 to the buckle structure 13. Specifically, the length of the traction rope 21 may be greater than the distance from the reinforcing component 22 on the connecting cable 1 to the buckle structure 13. The user can adjust the length of the traction rope 21 by stretching the connecting cable 1 as needed. Setting the length of the traction rope 21 longer allows for more flexible adjustment of the stretching direction of the connecting cable 1 and provides stability to the stretching direction.

[0072] In some specific embodiments, such as Figure 7 Side view diagram and Figure 8 As shown in the partial simplified schematic diagram, the pre-embedded structure 3 in the base layer includes a retaining wall.

[0073] In practical applications, multiple embedded parts 31 are distributed on the top surface of the retaining wall. The arrangement density and number of embedded parts 31 can be adjusted according to the stress distribution of the main body of the inflatable membrane 4. The multiple embedded parts 31 can be evenly arranged on the retaining wall, or they can be arranged more densely in the positions where the inflatable membrane 4 is under stronger stress than in other positions. Furthermore, the extension direction of the traction rope 21 is parallel to the top surface of the retaining wall.

[0074] It should be noted that this application does not specifically limit the relative angle between the connecting cable 1 and the retaining wall. In one specific embodiment, multiple connecting cables 1 are arranged perpendicular to the plane of the top surface of the retaining wall, forming a crisscrossing cable net system on the surface of the inflatable membrane 4. This is suitable for scenarios where the load generated by the inflatable membrane 4 is regularly distributed, and can form a uniform stress system; alternatively, it can be as follows... Figure 6 As shown, the connecting cable 1 is inclined relative to the plane containing the top surface of the retaining wall. Multiple connecting cables 1 are inclined and interlock, forming acute or obtuse angles, which can form a triangular or rhomboid cable net system on the surface of the inflatable membrane 4, such as... Figure 9 As shown, forming a bidirectional or tridirectional force system allows the load on the connecting cable 1 to be transmitted and dispersed in multiple directions, avoiding stress concentration.

[0075] In practical applications, the retaining wall is a concrete retaining wall used to fix the inflatable membrane 4, and the upper surface of the retaining wall is also provided with metal fasteners for fixing the inflatable membrane 4.

[0076] In some specific embodiments, the protective layer 12 includes a polyethylene protective layer, and / or a rubber protective layer, and / or a nylon protective layer. In practical applications, the steel cable 11 contains a steel bundle, and the outer surface of the steel cable 11 is covered with an insulating layer of polyethylene, wherein the thickness of the polyethylene protective layer ranges from 1.5 to 2.0 mm. In practice, the thickness of the polyethylene protective layer on the surface of the steel cable 11 varies depending on the specifications of the steel cable 11. For example, for conventional steel cables 16# and below, the thickness of the polyethylene protective layer is 1.5 mm; for steel cables 18# and above, the thickness of the polyethylene protective layer is 2.0 mm.

[0077] In one specific embodiment, depending on actual requirements, a partial protective sleeve may be further applied to the position on the connecting cable 1 where it is connected to the traction mechanism 2, so as to reduce the direct contact between the protective layer 12 and the traction mechanism 2 and extend the service life of the steel cable 11 and the protective layer 12.

[0078] This embodiment provides an inflatable membrane cable adjustment device, including a connecting cable, a traction mechanism, and a base layer pre-embedded structure. By setting a buckle structure on at least one end of the connecting cable and setting at least one end of the traction mechanism connected to the connecting cable, the other end of the traction mechanism is used to be externally tractioned to drive the connecting cable closer to the pre-embedded part. This can change the force direction of the connecting cable, decompose the force of the connecting cable and transfer it through the traction mechanism, adjust the position of the connecting cable relative to the surface of the inflatable membrane and the direction of installation movement, and not occupy the buckle structure of the connecting cable while traction is performed. This achieves the effect of the connecting cable passing through the surface of the inflatable membrane and quickly and detachably connecting to the pre-embedded part, which can effectively reduce the operation steps in traction, improve the installation efficiency of the connecting cable, and achieve stable installation of the inflatable membrane.

[0079] The above is a detailed description of the preferred embodiments of this application. However, the invention of this application is not limited to the embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of this application. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
