Description

Technical Field

[0001] This invention relates to the field of expansion joint filling technology, specifically to a stretchable aluminum alloy profile for expansion joints. Background Technology

[0002] Expansion joints, also known as expansion joints, are commonly found between buildings and on bridges. They are formed to prevent thermal expansion and contraction and reduce resonance between buildings, thereby improving stability and safety. Various materials are used to fill these joints, with aluminum alloy being just one method. When using aluminum alloy, it is typically corrugated to allow for stretching and compression, thus accommodating the deformation of the expansion joint. However, because the material is corrugated, prolonged use can lead to breakage at the joints. Breakage not only reduces building safety but also necessitates manual disassembly and replacement, increasing both the workload and maintenance costs. Furthermore, the stress and compressive elasticity of corrugated profiles are fixed during manufacturing and cannot be altered, limiting material versatility and reducing practicality and effectiveness.

[0003] Based on this, the present invention designs a stretchable aluminum alloy profile for expansion joints to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a stretchable aluminum alloy profile for expansion joints, so as to solve the problem mentioned in the background art that the material is prone to breakage due to long-term deformation during use.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A stretchable aluminum alloy profile for expansion joints includes an alloy plate, with multiple pairs of first springs fixedly connected inside the alloy plate. Multiple sliding grooves are provided on both the front and rear sides of the alloy plate, and sliding columns are slidably connected in the sliding grooves. A limiting mechanism is provided between every two sliding columns, and the limiting mechanism is located between each wave. Multiple reinforcing mechanisms are provided on the alloy plate, and the reinforcing mechanisms are located at the top of the wave.

[0007] As a further embodiment of the present invention, the alloy plate is corrugated, and the first spring is located between the corrugations of the alloy plate and the corrugations of the alloy plate.

[0008] As a further embodiment of the present invention, the limiting mechanism includes a fixed block, a telescopic mechanism, a threaded rod, a first conical tooth, a rotating rod, a second conical tooth, and an anti-blocking block. The fixed block is rotatably mounted on the sliding column, and a telescopic mechanism is provided between the two fixed blocks. A threaded rod is threadedly connected between the two fixed blocks. The threaded rod is a bidirectional thread, and a first conical tooth is mounted on the threaded rod. A rotating rod is rotatably connected to the telescopic mechanism, and a second conical tooth is mounted at one end of the rotating rod. The second conical tooth and the first conical tooth mesh with each other.

[0009] As a further embodiment of the present invention, an anti-slip block is installed at one end of the rotating rod, and the surface of the anti-slip block is provided with a rubber anti-slip layer.

[0010] As a further embodiment of the present invention, the telescopic mechanism includes a fixed shell, a limiting groove, a second spring, and a sliding plate. The fixed shell has limiting grooves on both the left and right sides. Two second springs are fixedly connected in the limiting grooves. A sliding plate is fixedly connected between the two second springs. One end of the sliding plate is fixedly connected to a fixed block.

[0011] As a further embodiment of the present invention, the reinforcement mechanism includes two connecting blocks, a rotating column and a torsion spring. Two connecting blocks are fixedly connected to the alloy plate, and a rotating column is rotatably connected between the two connecting blocks. A torsion spring is sleeved on the rotating column and is located between the two connecting blocks.

[0012] As a further embodiment of the present invention, mounting plates are provided on both the left and right sides of the alloy plate, the mounting plates are L-shaped, and the surface of the mounting plates is provided with an anti-corrosion coating.

[0013] As a further aspect of the present invention, the alloy plate is integrally pressed and molded, and the surface of the alloy plate is coated with an anti-corrosion coating.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] This invention controls and adjusts the distance of the limiting mechanism to suit the placement of the equipment in the expansion joint. Simultaneously, it changes the compression force of the alloy plate according to the needs of the expansion joint. During adjustment, the meshing of the first and second conical teeth causes the two fixing blocks to move closer or further apart, maintaining a constant wave distance within the alloy plate. This minimizes damage to the alloy plate during deformation and prevents damage when the force exceeds its maximum limit. The invention also allows for adjustment of the alloy plate's length to adapt to different expansion joints. When the alloy plate is placed within the expansion joint, the mounting plate is fixed for use. When the alloy plate is compressed or stretched, the length of the first spring is extended or compressed, and the spring force of the first spring can... To increase the stress on the alloy plate, the deformation force of the alloy plate is increased, avoiding damage to the equipment when deformation occurs due to insufficient deformation force of the alloy plate itself. During the deformation process, the alloy plate is squeezed into a wave shape, at which time the torsion spring is compressed, thereby further increasing the deformation force of the torsion spring. At the same time, when the alloy plate wave crest is repeatedly squeezed and stretched and eventually breaks during long-term use, the alloy plate in the equipment uses the first spring as the connection point, the rotating column and connecting block as the rotation point, and the torsion spring as the compression point, so that the equipment can still be used as filling material for the expansion joint. This reduces the need for equipment replacement and material consumption, making the equipment more convenient to use, more versatile in use, more durable, more effective, and more practical.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Please see Figures 1-6 The present invention provides a technical solution:

[0027] A stretchable aluminum alloy profile for expansion joints includes an alloy plate 1, with multiple pairs of first springs 2 fixedly connected inside the alloy plate 1. Multiple sliding grooves 3 are provided on both the front and rear sides of the alloy plate 1, and sliding columns 4 are slidably connected inside the sliding grooves 3. A limiting mechanism 5 is provided between every two sliding columns 4. The limiting mechanism 5 is located between each wave. Multiple reinforcing mechanisms 17 are provided on the alloy plate 1. The reinforcing mechanisms 17 are located at the top of the wave.

[0028] During operation, firstly, the limiting mechanism 5 is controlled, and its distance is adjusted to suit the placement of the equipment in the expansion joint. Simultaneously, the compression force of the alloy plate 1 is changed according to the needs of the expansion joint. During adjustment, the meshing of the first conical tooth 9 and the second conical tooth 11 causes the two fixing blocks 6 to move closer or further apart, thus maintaining a constant wave distance within the alloy plate 1. This minimizes damage to the alloy plate 1 during deformation and prevents damage when the force exceeds its maximum limit. The length of the alloy plate 1 can also be adjusted to adapt to different expansion joints. When the alloy plate 1 is placed within the expansion joint, the mounting plate 21 is fixed for use. When the alloy plate 1 is compressed or stretched, the length of the first spring 2 is extended or compressed, and the elastic force of the first spring 2 can... As the bearing of the alloy plate 1, the deformation force of the alloy plate 1 is increased, avoiding the situation where the deformation force of the alloy plate 1 is too small, which would lead to damage when the equipment is deformed. When the equipment is deformed, the alloy plate 1 is squeezed into a wave shape, at which time the torsion spring 20 is compressed, thereby further increasing the deformation force of the torsion spring 20. At the same time, when the crest of the alloy plate 1 is repeatedly squeezed and stretched and then breaks during long-term use, the alloy plate 1 in the equipment is connected by the first spring 2, and the rotating column 19 and the connecting block 18 are used as rotation points, and the torsion spring 20 is used as the pressure point, so that the equipment can still be used as filling material for the expansion joint, thereby reducing the need for equipment replacement and material consumption, making the equipment more convenient to use, more versatile in use, more durable, more effective, and more practical.

[0029] As a further embodiment of the present invention, the alloy plate 1 is corrugated, and the first spring 2 is located between the corrugations of the alloy plate 1;

[0030] During operation, when the alloy plate 1 is compressed by the deformation seal, the wave pattern of the alloy plate 1 contracts, and the first spring 2 is compressed simultaneously. When the deformation joint recovers, the first spring 2 resets. At this time, the first spring 2 is under the most force, which can effectively reduce the repeated folding force of the alloy plate 1, thereby effectively extending the service life of the alloy plate 1. When the alloy plate 1 breaks, the first spring 2, as a connecting part of the alloy plate 1, can continue to fill the deformation joint, allowing the internal parts to continue to work, thus making the equipment more convenient to operate and reducing material waste and replacement.

[0031] As a further embodiment of the present invention, the limiting mechanism 5 includes a fixed block 6, a telescopic mechanism 7, a threaded rod 8, a first conical tooth 9, a rotating rod 10, a second conical tooth 11, and an anti-slip block 12. The fixed block 6 is rotatably mounted on the sliding column 4. The telescopic mechanism 7 is provided between the two fixed blocks 6. The threaded rod 8 is threadedly connected between the two fixed blocks 6. The threaded rod 8 is a bidirectional thread. The first conical tooth 9 is installed on the threaded rod 8. The rotating rod 10 is rotatably connected to the telescopic mechanism 7. The second conical tooth 11 is installed at one end of the rotating rod 10. The second conical tooth 11 and the first conical tooth 9 mesh with each other.

[0032] During operation, rotating the rotating rod 10 causes the first conical tooth 9 to rotate. When the second conical tooth 11 rotates, it drives the first conical tooth 9 to rotate. When the first conical tooth 9 rotates, the threaded rod 8 rotates. When the threaded rod 8 rotates, the two fixed blocks 6 move closer or further apart, thereby pulling the waveform of the alloy plate 1 closer or further apart. When the waveform is subjected to pressure and moves closer or further apart, the sliding column 4 on the fixed block 6 slides in the groove 3, so that the limiting mechanism 5 can limit the movement without interfering with the deformation of the alloy plate 1. This makes the equipment more convenient and versatile to use. The movement of the waveform can effectively change the length of the alloy plate 1 and increase or decrease the force on the alloy plate 1, further making the equipment more convenient to use.

[0033] As a further embodiment of the present invention, a slider 12 is installed at one end of the rotating rod 10, and the surface of the slider 12 is provided with a rubber anti-slip layer.

[0034] During operation, the anti-slip block 12 can effectively increase the friction between the operator and the equipment, making the equipment more convenient to use and adjust, and further improving the ease of use of the equipment.

[0035] As a further embodiment of the present invention, the telescopic mechanism 7 includes a fixed shell 13, a limiting groove 14, a second spring 15 and a sliding plate 16. The fixed shell 13 has a limiting groove 14 on both the left and right sides. Two second springs 15 are fixedly connected in the limiting groove 14. A sliding plate 16 is fixedly connected between the two second springs 15. One end of the sliding plate 16 is fixedly connected to the fixed block 6.

[0036] During operation, when the two fixed blocks 6 approach each other, the sliding plate 16 slides within the limiting groove 14, thereby compressing the second spring 15. Conversely, when the two fixed blocks 6 move away from each other, the length of the second spring 15 is stretched, which in turn causes the sliding plate 16 and the fixed blocks 6 to move away from each other. This allows the device to maintain the meshing of the first conical tooth 9 and the second conical tooth 11 during use, making it more stable during operation.

[0037] As a further embodiment of the present invention, the reinforcement mechanism 17 includes two connecting blocks 18, a rotating column 19 and a torsion spring 20. Two connecting blocks 18 are fixedly connected to the alloy plate 1, and a rotating column 19 is rotatably connected between the two connecting blocks 18. A torsion spring 20 is sleeved on the rotating column 19 and is located between the two connecting blocks 18.

[0038] During operation, when the alloy plate 1 is compressed, the crest of the alloy plate 1 deforms. At this time, the connecting block 18 rotates around the rotating column 19 as the fulcrum, thereby compressing the torsion spring 20. When the torsion spring 20 is compressed, the elastic force of the alloy plate 1 increases simultaneously. When the crest of the alloy plate 1 is damaged or broken, the two connecting blocks 18 serve as the connection point of the alloy plate 1 and rotate around the rotating column 19 as the fulcrum. At this time, the torsion spring 20 becomes the point of force rebound, thus allowing the equipment to continue to be used, thereby reducing equipment replacement, making the equipment more convenient to use, and reducing resource waste.

[0039] As a further embodiment of the present invention, the alloy plate 1 is provided with mounting plates 21 on both the left and right sides. The mounting plates 21 are L-shaped and the surface of the mounting plates 21 is provided with an anti-corrosion coating.

[0040] During operation, the equipment is placed inside the expansion joint, and the mounting plate 21 is fixed in place, which makes the equipment more stable when it is in the expansion joint and avoids the equipment from shifting during use.

[0041] As a further embodiment of the present invention, the alloy plate 1 is integrally pressed and molded, and the surface of the alloy plate 1 is coated with an anti-corrosion coating.

[0042] During operation, the one-piece molded alloy plate 1 makes it more resilient and stable in use, while effectively extending the service life of the equipment. The anti-corrosion coating can also effectively extend the service life of the equipment.
