Description

Technical Field

[0001] This utility model relates to the field of building electromechanical installation technology, specifically to a pipeline fixing device inside a concrete structural column. Background Technology

[0002] In subway stations, integrated utility tunnels, and large public buildings, to optimize spatial layout and ensure aesthetics, some pipeline systems are often pre-embedded within structural columns. This practice requires the pipelines to be positioned and fixed before concrete pouring, and to ensure no displacement occurs during the pouring process. Currently, common fixing methods mainly include pre-embedded steel plate welding and pre-embedded rigid clips. Pre-embedded steel plate welding involves fixing the pre-embedded steel plate to the designed position during the column reinforcement binding stage; after the formwork is erected, pipeline supports or clamps are welded to the steel plate. Pre-embedded rigid clips involve directly binding plastic or metal clips to the reinforcement cage before concrete pouring, and then inserting the pipelines into them. However, both methods have the following shortcomings in practical applications: First, it lacks flexibility and adjustability. Whether it is a pre-embedded steel plate or a rigid clip, its position and specifications are determined before pouring. Once there are deviations in pipeline elevation or position during construction, or if pipelines need to be replaced or expanded due to functional adjustments later, the original fixing points are difficult to adjust. Often, destructive demolition and reconstruction are required, which increases the construction period and cost.

[0003] Secondly, the adaptability to pipeline specifications is limited. Existing embedded parts are usually designed for specific pipe diameters. When multiple pipelines of different diameters are laid in the column, multiple specifications of embedded parts need to be prepared, which increases the complexity of material management and construction and cannot achieve "one thing for multiple uses".

[0004] Finally, the seismic and disturbance resistance performance needs to be improved. Welding and rigid fastening are hard connections, and there is a lack of effective buffer between the pipeline and the structure. Under the conditions of earthquake or long-term structural micro-vibration, stress is directly transmitted to the pipeline and connection point, resulting in the potential risk of pipeline interface loosening or pipeline damage.

[0005] Therefore, there is an urgent need for a pipeline fixing device in concrete structural columns that can adjust the pipeline position, adapt to various pipe diameters, and has buffering performance. Summary of the Invention

[0006] The purpose of this utility model is to provide a pipeline fixing device inside a concrete structural column, so as to at least solve the problems of current pipeline fixing devices inside columns being unable to adjust the position of pipelines, having limited adaptability, and lacking buffering.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A pipeline fixing device inside a concrete structural column includes multiple mounting blocks and connecting blocks; The mounting blocks are pre-embedded vertically within the column body; The connecting block has a sliding groove extending from top to bottom. The connecting block is sleeved on the mounting block through the sliding groove and fixed by a locking mechanism. The locking mechanism includes a support spring, a locking pin, and a locking hole. The locking pin is disposed on the front side of the support spring. The support spring and the locking pin are embedded in the mounting block. The locking hole is opened on the front side of the connecting block. Multiple clamping and buffering mechanisms are provided on the front side of the connecting block below the locking hole, and pipelines are fixed in the clamping and buffering mechanisms respectively.

[0008] Furthermore, the mounting block has an L-shaped vertical cross-section, and the connecting block is disposed on the vertical section of the mounting block. Furthermore, the vertical section of the mounting block has a through mounting hole.

[0009] Furthermore, the locking hole extends from the front side of the connecting block into the interior of the sliding groove.

[0010] Furthermore, the clamping and buffering mechanism includes two symmetrically arranged single-sided clamping components, and the pipeline is disposed between the two single-sided clamping components.

[0011] Furthermore, the single-sided clamping component includes a fastening block and a clamping block. The side end of the fastening block is located on the front side of the connecting block. The fastening block has multiple guide holes and multiple clamping springs on the side near the clamping block. The clamping block has multiple guide posts corresponding to the guide holes on the side near the fastening block. The clamping block is fixed to the fastening block by the guide posts.

[0012] Furthermore, the side of the clamping block away from the fastening block is arc-shaped, and the curvature of the arc is concave towards the side closer to the fastening block.

[0013] Furthermore, a rubber pad is provided on the arc-shaped side of the clamping block.

[0014] Furthermore, permanent magnets are embedded in the end of the locking post away from the supporting spring and in the locking hole, respectively.

[0015] Furthermore, the single-sided clamping component includes a fastening block and a flexible pouch. The side end of the fastening block is disposed on the front side of the connecting block, and the flexible pouch is disposed on the fastening block. The flexible pouch is connected to a manual pump.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model provides a pipeline fixing device inside a concrete structural column, which is equipped with multiple mounting blocks and connecting blocks. The connecting blocks are provided with sliding grooves, which allow the connecting blocks to slide and engage with mounting blocks of different heights. Furthermore, a locking column driven by a support spring forms a locking structure with the locking hole, thereby realizing rapid position adjustment and fixing of the connecting blocks on the mounting blocks. Even after the concrete is poured, the pipeline installation height can still be flexibly adjusted, greatly facilitating error correction during the construction phase and maintenance operations such as pipeline expansion and replacement during the usage phase. The deformation of the clamping spring in the clamping buffer mechanism allows the clamping blocks to automatically adapt to pipelines of different diameters, significantly reducing the requirement for the number of pre-embedded parts, reducing material management costs and inventory pressure, and improving the versatility of the device.

[0017] 2. The clamping spring and the rubber pad of the clamping block together form an elastic damping system. When an earthquake or structural micro-vibration occurs, this elastic damping system can effectively absorb and attenuate the vibration energy transmitted to the pipeline, buffer rigid impact, thereby greatly reducing the risk of pipeline and connection point damage due to stress concentration, and improving the safety and reliability of the entire pipeline system.

[0018] 3. The installation process of this utility model does not require complex operations such as on-site welding and drilling, which simplifies the installation process, greatly improves the installation speed, significantly improves the construction efficiency, and avoids open flame, smoke and dust pollution caused by welding, thus saving energy and protecting the environment.

The drawings illustrate preferred embodiments of this utility model. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

Therefore, they should not be construed as limitations on this utility model.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] Example 1: like Figure 1 and Figure 5 As shown, this embodiment provides a pipeline fixing device for a concrete structure column, which is set between the column 1 and the dry-hanging exterior wall. It includes three mounting blocks 2, connecting blocks 3, locking mechanisms and two clamping buffer mechanisms 4. The mounting blocks 2 are embedded in the column 1 as the foundation. The connecting blocks 3 are slidably connected to the mounting blocks 2 and fixed by the locking mechanisms. The clamping buffer mechanisms 4 are fixed on the connecting blocks 3 to form the final pipeline clamping unit.

[0025] Specifically, such as Figure 2 As shown, the mounting blocks 2 are embedded vertically in the column 1. The vertical cross section of the mounting block 2 is L-shaped, which facilitates the provision of a stable anchoring foundation. The vertical section of the mounting block 2 is provided with a mounting hole near the top. One mounting hole is provided on each mounting block 2.

[0026] In this embodiment, as Figure 3 As shown, the connecting block 3 has a sliding groove 301 extending from the top to the bottom. The connecting block 3 is fitted onto the vertical section of the mounting block 2 through the sliding groove 301. The outer surface of the vertical section of the mounting block 2 is in contact with the inner wall of the sliding groove 301. By fitting the connecting block 3 onto the mounting blocks 2 at different heights, the final installation height of the connecting block 3 can be adjusted. The connecting block 3 is fixed by a locking mechanism. In other embodiments, the number of connecting blocks 3 can be set according to actual needs.

[0027] The locking mechanism includes a support spring 201, a locking pin 202, and a locking hole 302. The locking pin 202 is welded and fixed to the front side of the support spring 201. The rear side of the support spring 201, away from the locking pin 202, is welded and fixed to the mounting hole of the mounting block 2. The diameter of the locking pin 202 is smaller than the inner diameter of the mounting hole. The locking hole 302 is located on the front side of the connecting block 3 and extends from the front side of the connecting block 3 into the interior of the sliding groove 301. The locking hole 302 is the same size as the mounting hole. Before the connecting block 3 is fitted, the support spring 201 is in a free length state. Before the connecting block 3 is fitted, pressing the locking pin 202 applies pressure to the support spring 201. Applying pressure compresses the support spring 201 until the front end of the locking pin 202 is on the same plane as the front end of the mounting block 2. The support spring 201 provides continuous elastic force to the locking pin 202, which then fits onto the connecting block 3. After the connecting block 3 is fitted onto and presses down on the locking pin 202, the pressure on the locking pin 202 is released, and the connecting block 3 compresses the locking pin 202 until the locking hole 302 of the connecting block 3 is aligned with the mounting hole of the mounting block 2. The locking pin 202 can then automatically engage with the corresponding locking hole 302 by the elastic force of the support spring 201, thereby fixing the connecting block 3 and facilitating subsequent disassembly and maintenance.

[0028] The connecting block 3 slides with the mounting blocks 2 at different heights via the sliding groove 301, and the locking pin 202 is driven by the support spring 201 to engage with the locking hole 302, so that the connecting block 3 can be quickly adjusted and fixed in position. This allows the installation height of the pipeline to be flexibly adjusted even after the concrete is poured, which greatly facilitates error correction during the construction phase and pipeline expansion, replacement and other maintenance operations during the use phase.

[0029] Specifically, in use, first press the locking pin 202, then put the connecting block 3 on, so that it contacts the outer surface of the mounting block 2 through the sliding groove 301 until the locking hole 302 is aligned with the locking pin 202. Then the compressed support spring 201 extends and drives the locking pin 202 to engage with the locking hole 302, thereby achieving the installation and fixation of the connecting block 3.

[0030] In this embodiment, two clamping buffer mechanisms 4 are provided on the front side of the connecting block 3 below the locking hole 302. The two clamping buffer mechanisms 4 are arranged horizontally and closely attached to each other, and pipelines are fixed in the clamping buffer mechanisms 4 respectively.

[0031] Specifically, the clamping and buffering mechanism 4 includes two symmetrically arranged single-sided clamping components, with the pipeline disposed between the two single-sided clamping components.

[0032] Among them, such as Figure 4 As shown, the single-sided clamping component includes a fastening block 401 and a clamping block 404. The side end of the fastening block 401 is welded and fixed to the front side of the connecting block 3. Two guide holes 402 are symmetrically opened vertically on the side of the fastening block 401 near the clamping block 404, and two clamping springs 403 are symmetrically welded and fixed horizontally on the side of the clamping block 404 near the fastening block 401. Two guide posts 405 are symmetrically welded and fixed vertically on the side of the clamping block 404 near the fastening block 401. The guide posts 405 are respectively arranged corresponding to the guide holes 402. The clamping block 404 is connected to the fastening block 401 through the guide posts 405. The guide hole 402 on the upper part is used to achieve precise lateral guidance and is fixed on the fastening block 401. The two ends of the clamping spring 403 are welded and fixed to the fastening block 401 and the clamping block 404 respectively. In this embodiment, the clamping spring 403 is a high-strength helical spring. The clamping spring 403 is set between the fastening block 401 and the clamping block 404 to provide a continuous radial clamping force. The clamping spring 403 applies an elastic thrust to the clamping block 404, so that the clamping block 404 can smoothly approach the outer surface of the pipeline, thereby fixing the pipeline.

[0033] The clamping block 404 is arc-shaped on the side away from the fastening block 401, and the arc is concave on the side closer to the fastening block 401, so that the clamping block 404 can fit more closely to the outer surface of the pipeline.

[0034] In this embodiment, a rubber pad is provided on the arc-shaped side of the clamping block 404. On the one hand, it increases the static friction with the pipeline surface, ensuring the firmness of the clamping and preventing the pipeline from slipping off. On the other hand, as a flexible medium, it avoids the metal clamping block 404 from directly contacting the outer wall of the pipeline, effectively preventing scratches or wear on the pipeline surface during fixing and vibration.

[0035] Specifically, the pipeline to be fixed is perpendicular to the surface of the column 1, aligned with the gap between the two clamping blocks 404, and the pipeline is pushed inward with force. The pipeline overcomes the force of the clamping spring 403 and pushes the two clamping blocks 404 to the sides. When the pipeline is fully inserted, the rebound force of the clamping spring 403 firmly holds the pipeline through the clamping blocks 404 and the rubber pad, thereby achieving the function of fixing the pipeline.

[0036] When it is necessary to disassemble the connecting block 3, press the locking pin 202 to compress the support spring 201 until the locking pin 202 exits from the locking hole 302. At this time, move the connecting block 3 upward. After the connecting block 3 presses down on the locking pin 202, release the pressure on the locking pin 202. The connecting block 3 continues to move upward along the vertical section of the mounting block 2 and disengages, thereby disassembling the connecting block 3 and meeting the needs of maintenance personnel.

[0037] In this embodiment, the clamping spring 403 can flexibly clamp and fix pipelines with different outer diameters, thereby reducing the variety of embedded parts, reducing material management costs and construction complexity. Furthermore, the clamping spring 403 and the rubber pad on the clamping block 404 together form an elastic damping system. When an earthquake or structural micro-vibration occurs, this elastic damping system can effectively absorb and attenuate the vibration energy transmitted to the pipeline, buffering rigid impacts, thereby significantly reducing the risk of pipeline and connection point damage due to stress concentration, and improving the safety and reliability of the entire pipeline system.

[0038] In this embodiment, a modular design and a "sliding-clamping" quick locking mechanism are adopted. The installation process does not require complex operations such as on-site welding and drilling, which simplifies the installation process, greatly improves the installation speed, and avoids open flame, smoke and dust pollution caused by welding, which meets the requirements of green and efficient modern construction.

[0039] The installation process in this embodiment is as follows: 1. Pre-embedding stage During the reinforcement binding process of column 1, three installation blocks 2 are fixed vertically to the reinforcement cage according to the design elevation and position, and then concrete is poured.

[0040] 2. Main body installation After the concrete has set, according to the target elevation, the connecting block 3 is aligned with the corresponding height of the mounting block 2 through the sliding groove 301 and inserted from top to bottom until the locking hole 302 is aligned with the locking post 202. At this time, under the action of the support spring 201, the locking post 202 automatically pops out and locks into the locking hole 302 at that position, thereby completing the quick fixing of the connecting block 3.

[0041] 3. Pipeline laying The pipeline is placed between the left and right symmetrical clamping blocks 404. Under the pushing force of the clamping spring 403, the two clamping blocks 404 move synchronously towards each other and adaptively adhere to and hug the pipeline through the friction pads on their inner sides, thereby completing the fixation of the pipeline.

[0042] Example 2: In this embodiment, permanent magnets are embedded in the end of the locking pin away from the support spring and in the locking hole, respectively. Preferably, the permanent magnets are neodymium iron boron magnets. When the locking pin approaches or enters the locking hole, the magnetic force of the permanent magnets will assist the locking pin in being attracted and centered, providing additional holding force to prevent accidental disengagement in a vibration environment, thereby further enhancing the reliability and vibration resistance of the locking mechanism.

[0043] The remaining structure and principle are the same as in Example 1.

[0044] Example 3: In this embodiment, the single-sided clamping component includes a fastening block and a flexible bladder. The side end of the fastening block is welded and fixed to the front side of the connecting block. The flexible bladder is fixed to the fastening block by bolts. The flexible bladder is connected to a manual pump through a micro-tube. In other embodiments, the flexible bladder can also be connected to an inflation / deflation valve. By injecting fluid (oil or air) into the flexible bladder, it expands to clamp the pipeline. The clamping force can be precisely controlled and can adapt to extremely irregular pipeline surfaces. It can also be remotely controlled and is suitable for special or high-risk environments.

[0045] The remaining structure and principle are the same as in Example 1.

[0046] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention. Those skilled in the art to which this invention pertains can make various simple deductions, modifications, or substitutions based on the concept of this invention.
