Description

Technical Field

[0001] This utility model belongs to the field of earthquake-resistant structure technology, and in particular relates to an earthquake-resistant structure for civil engineering. Background Technology

[0002] In the field of civil engineering, pipeline systems serve as the core carriers of basic functions such as water supply and drainage, gas transmission, heating and ventilation. Their operational stability is directly related to the normal functioning and safety of the overall building. Especially in areas with frequent seismic activity or in scenarios where there are vibration sources of equipment nearby, pipelines are prone to radial displacement, axial movement, or even torsional deformation due to external impacts and vibrations, which can lead to faults such as loose joints and cracked pipe walls. This not only affects the efficiency of medium transportation but may also lead to safety hazards such as leakage and explosion. Therefore, the design and application of seismic-resistant pipeline structures are receiving increasing attention.

[0003] Chinese patent application CN221443556U discloses a seismic-resistant structure for civil engineering, including an upper clamp, a lower clamp, and a rectangular frame. The upper clamp is located above the lower clamp, and both the upper and lower clamps are located inside the rectangular frame. A first connecting block is welded to both sides of the outer wall of the upper clamp and both sides of the outer wall of the lower clamp. A second connecting block is welded to each of the four corners inside the rectangular frame. Through the cooperation of the first and second connecting holes and connecting bolts, the upper and lower clamps can be connected to limit the movement of the pipeline. Through the cooperation of the first and second connecting blocks and connecting plates, the combination of the upper and lower clamps can be connected to the rectangular frame. When the pipeline vibrates due to external factors, the four hydraulic dampers can absorb and mitigate the vibration, thereby reducing the loosening of the pipeline caused by external vibration and enhancing its stability.

[0004] While this patent achieves pipe positioning through the mating clamping of the upper and lower clamps, and the inner wall shock-absorbing pad reduces rigid friction between the pipe and the clamps, the hinged assembly of the first and second connecting blocks and the hydraulic damper transfers the pipe vibration energy to the damper for absorption, effectively alleviating pipe loosening caused by vibration and enhancing pipe stability. However, this structure has significant limitations. The cross-sectional dimensions of the upper and lower clamps are fixed, and the clamping space formed by their combination cannot be adjusted, resulting in the device only being able to adapt to pipes of specific diameters. In civil engineering scenarios such as parallel laying of multiple pipe diameters and renovation of old pipelines, it is necessary to frequently replace components of different specifications, resulting in extremely poor versatility. At the same time, the connection position between the hydraulic damper and the connecting block is fixed, and its deformable buffer stroke cannot be adjusted according to the pipe weight, vibration intensity, and other working conditions. When dealing with lightly loaded pipes, excessive buffering force can easily lead to over-clamping, while under heavy loads or strong earthquakes, insufficient buffering distance can easily cause rigid collisions, making it difficult to achieve targeted seismic protection.

[0005] To address these issues, we provide a seismic-resistant civil engineering structure. Utility Model Content

[0006] The purpose of this utility model is to provide a seismic-resistant structure for civil engineering. By combining seismic-resistant components and adjustment components, it solves the problem that existing seismic-resistant structures for civil engineering cannot adapt to pipes of different diameters and cannot achieve targeted protection.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0008] This utility model relates to a seismic-resistant structure for civil engineering, comprising a fixed plate, a seismic-resistant component on one side of the fixed plate, and an adjusting component on one side of the seismic-resistant component. The seismic-resistant component includes a bidirectional lead screw, one side of which is rotatably connected to the fixed plate, and the other side of which penetrates the inner side of the fixed plate and extends to one side of the fixed plate. A movable plate is threadedly connected to the surface of the bidirectional lead screw, and the bottom of the movable plate is slidably connected to the fixed plate. A guide rod is slidably connected to the inner cavity of the movable plate, and a limit plate is fixedly connected to the other side of the guide rod. A spring is provided on the surface of the guide rod, one side of which is fixedly connected to the movable plate. Connecting rods are movably connected to both sides of the limit plate. A buffer block is movably connected to the other side of the connecting rod. A slot is opened on one side of the moving plate, and one side of the buffer block is slidably connected to the slot. A friction pad is provided on the surface of the buffer block, and the other side of the friction pad is fixedly connected to the moving plate. The limiting plate is semi-arc and has a buffer pad fixedly connected to its inner side, which can increase the contact area between the two and avoid the problems of local stress and poor fit that are easy to occur in planar limiting. The buffer pad can form a flexible contact when clamping the pipe fitting, avoiding damage to the pipe wall caused by direct rigid friction between the limiting plate and the pipe fitting. There are two limiting plates, which are symmetrically distributed on both sides of the bidirectional screw. The surface of the fixed plate is provided with mounting holes, and the device can be quickly installed in the designated position by bolts and other connecting parts.

[0009] The present invention is further configured such that the adjusting component includes an adjusting screw, the surface of which is slidably connected to a moving plate, the other side of which passes through the inner side of the moving plate and is threadedly connected to an adjusting plate, the bottom of which is slidably connected to the moving plate, a limit block is provided on one side of the adjusting plate, and one side of the limit block is fixedly connected to the adjusting screw. The self-locking property of the adjusting screw can ensure that the determined spring preload and buffer stroke do not deviate under complex working conditions such as long-term pipeline vibration and equipment operation impact.

[0010] The present invention is further provided with a rotating handle on one side of the fixed plate, and one side of the rotating handle is fixedly connected to a bidirectional lead screw. The rotating handle provides the operator with a more convenient bidirectional lead screw drive component.

[0011] The present invention is further configured such that a limiting rod is fixedly connected to the bottom of the fixed plate, and the surface of the limiting rod is slidably connected to the moving plate, thereby limiting the movement of the limiting plate.

[0012] The present invention is further configured such that a knob is provided on the inner side of the movable plate, and one side of the knob is fixedly connected to the adjusting screw. The knob can increase the contact area between the hand and the adjusting screw, thereby improving the convenience of the device.

[0013] The present invention is further configured such that a sliding rod is slidably connected to the bottom of the adjusting plate, and the other side of the sliding rod penetrates the surface of the adjusting plate and is fixedly connected to the moving plate. The sliding rod provides precise positioning and guidance for the adjusting plate.

[0014] The present invention is further configured such that a limiting groove is formed in the inner cavity of the moving plate, a limiting ring is slidably connected to the inner cavity of the limiting groove, and the inner side of the limiting ring is fixedly connected to the adjusting screw. The setting of the limiting groove and the limiting ring can limit the range of motion and operation mode of the adjusting screw.

[0015] The present invention is further configured such that a damping sleeve is provided on the surface of the guide rod, and one side of the damping sleeve is fixedly connected to the moving plate. The damping sleeve can increase the friction between the moving plate and the guide rod, and further reduce the return speed of the spring.

[0016] The present invention has the following beneficial effects.

[0017] 1. This utility model's seismic-resistant component can drive a movable plate to slide along a fixed plate via a bidirectional screw. By adjusting the distance between the two movable plates, it can flexibly adapt to pipes of different diameters, eliminating the need for custom-made components for specific pipe diameters. This effectively solves the problems of narrow adaptability and poor versatility of traditional fixed-size seismic-resistant structures, significantly reducing component replacement costs during construction and maintenance. When the pipeline vibrates, the limiting plate drives the guide rod to compress the spring, and the spring initially absorbs vibration energy through elastic deformation. At the same time, the limiting plate pushes the connecting rod, driving the buffer block to slide along the groove. The friction between the buffer block and the friction pad can further convert vibration energy into internal energy consumption.

[0018] 2. The adjustment component of this utility model drives the adjustment plate to slide along the moving plate by rotating the adjustment screw and using the threaded transmission. The adjustment plate can apply targeted tightening or loosening to the spring, thereby flexibly changing the initial preload and deformable buffer stroke of the spring. This solves the problem that the spring buffer parameters in traditional seismic structures are fixed and cannot be adapted to different working conditions. It can adjust the shock absorption performance according to the actual needs such as pipeline weight and vibration intensity, avoiding insufficient buffering under light load or excessive compression failure of the spring under heavy load.

[0028] Specifically: The limiting plate 204 is semi-arc and has a buffer pad fixedly connected to its inner side, which can increase the contact area between the two and avoid the problems of local stress and poor fit that are easy to occur in planar limiting. The buffer pad can form a flexible contact when clamping the pipe fitting, avoiding damage to the pipe wall caused by direct rigid friction between the limiting plate 204 and the pipe fitting. There are two limiting plates 204, which are symmetrically distributed on both sides of the bidirectional screw 201. The surface of the fixing plate 1 is provided with mounting holes, and the device can be quickly installed in the designated position through bolts and other connecting parts. Example

[0029] Please see Figure 1-5 Based on Embodiment 1, the adjusting assembly 3 includes an adjusting screw 301, the surface of which is slidably connected to the moving plate 202. The other side of the adjusting screw 301 passes through the inner side of the moving plate 202 and is threadedly connected to the adjusting plate 302. The bottom of the adjusting plate 302 is slidably connected to the moving plate 202. A limit block 303 is provided on one side of the adjusting plate 302, and one side of the limit block 303 is fixedly connected to the adjusting screw 301. A handle 4 is provided on one side of the fixed plate 1, and one side of the handle 4 is fixedly connected to the bidirectional screw 201. A limit rod 5 is fixedly connected to the bottom of the fixed plate 1. The surface of the limiting rod 5 is slidably connected to the moving plate 202. A knob 6 is provided on the inner side of the moving plate 202. One side of the knob 6 is fixedly connected to the adjusting screw 301. A slide rod 7 is slidably connected to the bottom of the adjusting plate 302. The other side of the slide rod 7 passes through the surface of the adjusting plate 302 and is fixedly connected to the moving plate 202. A limiting groove 8 is opened in the inner cavity of the moving plate 202. A limiting ring 9 is slidably connected to the inner cavity of the limiting groove 8. The inner side of the limiting ring 9 is fixedly connected to the adjusting screw 301. A damping sleeve 10 is provided on the surface of the guide rod 203. One side of the damping sleeve 10 is fixedly connected to the moving plate 202.

[0030] Specifically: the self-locking property of the adjusting screw 301 ensures that the preload and buffer stroke of the adjusted spring 205 do not deviate under complex working conditions such as long-term pipeline vibration and equipment operation impact; the handle 4 provides workers with a more convenient bidirectional driving component for the screw 201; the limit rod 5 restricts the movement of the moving plate 202; the knob 6 increases the contact area between the hand and the adjusting screw 301, improving the convenience of the device; the slide rod 7 provides precise positioning and guidance for the adjusting plate 302; the setting of the limit groove 8 and the limit ring 9 restricts the range of motion and operation of the adjusting screw 301; and the damping sleeve 10 increases the friction between the moving plate 202 and the guide rod 203, further reducing the reset speed of the spring 205.

[0031] The working principle of this utility model is as follows: In use, the fixing plate 1 is installed in the designated position through the mounting hole, and the pipe is placed inside the limiting plate 204. The knob 6 is turned, which drives the adjusting screw 301 to rotate. The adjusting screw 301 drives the adjusting plate 302 to move along the slide rod 7 and drives the guide rod 203 to move. The guide rod 203 moves, which drives the limiting plate 204 to move and compresses the spring 205. After adjusting to the appropriate preload and buffer distance, the handle 4 is turned. The handle 4 drives the bidirectional screw 201 to rotate and drives the two moving plates 202 on both sides to move inward at the same time. The moving plates 202 move inward through the guide rod 204. The guide rod 203 moves the limiting plate 204 and clamps and limits the pipe fitting. When subjected to impact force, the limiting plate 204, as the first part in contact with the pipe fitting, will be squeezed and moved. The movement of the limiting plate 204 drives the guide rod 203 to move and compress the spring 205. At the same time, it pushes the connecting rods 206 on both sides. The connecting rods 206 push the buffer block 207 to move along the slot 208 and convert the impact force into internal energy consumption through the friction pad 209. When the impact force disappears, the spring 205 extends and drives the limiting plate 204 and the guide rod 203 to reset. The connecting rods 206 and the buffer block 207 follow the limiting plate 204 to reset.
