Description

Technical Field

[0001] This invention relates to the field of pipeline installation technology in building engineering, specifically to a pipeline installation bracket for building engineering and its operation method. Background Technology

[0002] In building construction, the overhead installation of various pipelines, such as water supply and drainage, HVAC, fire protection, and electrical cable trays, is an essential procedure. Currently, conventional pipeline installation supports are mostly fixed angle steel supports, which, together with U-bolts, clamps, and other fasteners, are used to press and fix the pipelines. During the installation process, workers need to use wrenches and other tools to tighten each fastener one by one. In high-altitude work scenarios, the operating space is limited, the construction is difficult, and a single pipeline needs to be tightened in multiple places, resulting in low overall installation efficiency and cumbersome subsequent maintenance and disassembly.

[0003] Some existing flexible clamping pipe supports rely on spring force to clamp the pipes. While this eliminates the need for fasteners, they generally lack a reliable rigid locking structure. During building use, when pipes are affected by factors such as fluid impact, thermal expansion and contraction due to temperature changes, and building structural vibrations, the clamping force is prone to weakening, leading to pipe loosening, displacement, or even detachment. This poses safety hazards and fails to meet the long-term stable fixing requirements of building projects.

[0004] Therefore, we propose a pipe installation bracket for building engineering and its operation method to solve the above problems. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the present invention provides a pipe installation bracket for building engineering and an operating method thereof. The pipe installation bracket provided by the present invention includes a base, a secondary lifting seat slidably connected to the top of the base, a first spring installed between the bottom of the secondary lifting seat and the inner wall of the bottom of the base, an installation groove provided at the center of the top of the secondary lifting seat, a primary lifting seat slidably connected within the installation groove along the Z-axis direction, and limiting grooves on both sides of the primary lifting seat. Clamping arms for clamping pipes are hinged to each limiting groove via hinge shafts. Torsion springs are sleeved on the hinge shafts, and the two ends of the torsion springs are respectively engaged with the clamping arms and the primary lifting seat. The top of the secondary lifting seat is provided with contour grooves on both sides of the mounting groove for fitting the outer wall of the clamping arm. When the pipe is not installed on the bracket, under the action of the torsion spring, when the outer wall of the clamping arm contacts the bottom wall of the limiting groove, the clamping arm is in an open state, and the top of the primary lifting seat extends out of the mounting groove. The outer wall of the clamping arm is in tangential contact with the secondary lifting seat. When the pipe is installed on the bracket, the pipe presses down on the primary lifting seat under its own weight, overcoming the torsion of the torsion spring. The primary lifting seat is fully installed in the mounting groove, and the contour groove is fully fitted and contacted with the outer wall of the clamping arm. The two clamping arms are on the same circumference and wrap around the pipe. The first-stage lifting seat has a locking hole on its side wall, and the second-stage lifting seat is equipped with a locking component that mates with the locking hole.

[0006] Preferably, a guide rod is fixed to the bottom inner wall of the base, and a first spring is sleeved on the outside of the guide rod. The bottom of the secondary lifting seat is provided with a receiving groove, and the guide rod is slidably connected in the receiving groove. Preferably, the side wall of the secondary lifting seat is provided with a waist-shaped anti-detachment groove, and an anti-detachment screw is threadedly connected to the base, with the threaded end of the anti-detachment screw set in the waist-shaped anti-detachment groove.

[0007] Preferably, the bottom of the primary lifting seat is symmetrically fixed with stepped anti-detachment rods, and the secondary lifting seat is provided with stepped holes, with the stepped anti-detachment rods slidably connected in the stepped holes.

[0008] Preferably, the locking assembly includes a slider, a locking rod, and a second spring. The secondary lifting seat has a groove, and the slider is slidably connected to the groove. A locking rod that mates with a locking hole is fixed on the slider. A second spring is installed between one side wall of the slider and the side wall of the groove to allow the locking rod to move out of the locking hole. The bottom of the slider has a first inclined surface. A drive rod is fixed to the bottom inner wall of the base. The secondary lifting seat has a clearance hole for avoiding the drive rod. The top of the drive rod has a second inclined surface that mates with the first inclined surface. Preferably, the end of the locking rod has a chamfer.

[0009] Preferably, there is a travel clearance between the second inclined surface at the top of the drive rod and the first inclined surface at the bottom of the slider.

[0010] Preferably, the top surface of the primary lifting seat is provided with a first contoured surface that mates with the outer wall of the pipe. Preferably, the top surface of the secondary lifting seat is provided with a second contoured surface that mates with the outer wall of the pipe, and when the locking hole mates with the locking rod, the first contoured surface and the second contoured surface are flush.

[0011] The present invention also provides an operating method for the pipe installation bracket used in the above-mentioned building engineering, comprising the following steps: S1 Initial standby preparation: The bracket is in a standby state without pipes installed. The first spring elastically supports the second-stage lifting seat upward to the upper limit position. The force of the torsion spring drives the clamping arm to open outward. The top of the first-stage lifting seat extends out of the mounting slot, and the locking component is in the unlocked state. S2 Pipe Placement and Clamp Arm Retraction: Place the pipe to be installed horizontally on the top surface of the first-stage lifting seat. The pipe presses down on the first-stage lifting seat by its own weight, causing the first-stage lifting seat to slide into the installation groove along the Z-axis. The clamp arm moves down synchronously with the first-stage lifting seat and retracts inward against the torsion of the torsion spring under the constraint of the inner wall of the contour groove. S3 First-stage seating and radial clamping: When the first-stage lifting seat is fully inserted into the installation groove, the outer walls of the two clamping arms are fully adapted and fitted to the contour groove, and the two clamping arms enclose and clamp the outer wall of the pipe to complete the radial clamping and positioning of the pipe. S4 Secondary Descending and Automatic Locking: Under its own gravity, the pipeline continues to descend, and the load is transferred to the secondary lifting seat, causing it to overcome the elastic force of the first spring and slide down into the base. The drive rod fixed to the bottom of the base moves upward relative to the secondary lifting seat. Through the cooperation of the inclined surfaces of the first and second inclined surfaces, the slider is pushed to slide laterally, so that the locking rod is inserted into the locking hole on the side wall of the primary lifting seat, completing the relative position locking of the primary and secondary lifting seats, and the pipeline installation and fixing are completed.

[0012] Compared with related technologies, the pipe installation bracket and operating method for building engineering provided by the present invention have the following beneficial effects: The support relies entirely on the pipe's own weight to trigger the clamping and locking action. No bolts or additional tools are required. Simply lower the pipe onto the support to automatically fix it, greatly reducing the difficulty of high-altitude pipe installation and significantly improving construction efficiency.

[0013] It adopts a two-stage sliding structure with a primary lifting seat and a secondary lifting seat connected in series, strictly following the action sequence of "first clamping the pipe with the clamping arm, then triggering the mechanical lock". The locking timing is controlled by the stroke gap to ensure that the clamping is fully in place before locking, thus avoiding the clamping failure problem caused by premature locking from the structure.

[0014] The two clamping arms form a complete circumferential surface to tightly hold the pipe. Combined with the rigid mechanical locking rod and locking hole, it can effectively resist the impact of pipe fluid, thermal expansion and contraction and external force disturbance caused by building vibration, eliminate the risk of loosening and displacement, and meet the long-term stable and fixed use requirements of building engineering.

[0015] The locking component is fully integrated inside the secondary lifting platform. It is automatically triggered by the vertical displacement of the secondary lifting platform. No additional drive components or power source are required. The overall structure is simple and compact, with low manufacturing cost. It also has no easily damaged electrical components, long service life, and low maintenance cost. Attached Figure Description

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0019] Please refer to the following: Figures 1 to 6 A pipe installation bracket for building engineering is mainly used for the overhead installation and fixing of various pipes such as water supply and drainage pipes, fire protection pipes, HVAC pipes, and cable trays in building engineering. The whole system relies on the gravity of the iron pipe itself to trigger the clamping and locking action, without the need for additional fastening tools, which can realize the rapid installation and reliable fixing of pipes.

[0020] I. Overall Structural Composition The pipe installation bracket mainly consists of three parts: a base bearing mechanism, a primary clamping mechanism, and a secondary locking mechanism. Specifically, it includes a base 1, a secondary lifting seat 2, a first spring 3, a primary lifting seat 5, a clamping arm 8, a torsion spring 9, and a locking assembly 12.

[0021] The base 1, serving as the mounting base for the overall support, adopts a grooved shell structure with an open top and an internal vertical mounting cavity. The bottom of the base 1 can be fixed to building walls, beams, columns, floor slabs, or cable tray beams using expansion bolts, providing a stable mounting foundation for the entire support. The secondary lifting seat 2 is integrally embedded in the mounting cavity of the base 1 and can slide smoothly relative to the base 1 vertically (Z-axis direction). The first spring 3 is vertically positioned between the bottom end face of the secondary lifting seat 2 and the bottom inner wall of the base 1, providing continuous upward elastic support for the secondary lifting seat 2, normally lifting it to its maximum lifting position.

[0022] The top center of the secondary lifting seat 2 has an installation groove 4 extending downward along the Z-axis. The primary lifting seat 5 is slidably installed in the installation groove 4 and can slide vertically up and down along the inner wall of the installation groove 4. The left and right sides of the primary lifting seat 5 have symmetrical limit grooves 6. The inside of each limit groove 6 is hinged to a clamping arm 8 through a horizontally arranged hinge shaft 7. The clamping arm 8 can rotate around the hinge shaft 7 within a certain angle range. The two clamping arms 8 are symmetrically arranged to clamp the outer wall of the pipe from the left and right sides.

[0023] Each hinge shaft 7 is fitted with a torsion spring 9. One end of the torsion spring 9 is fixed to the side wall of the clamping arm 8, and the other end is fixed to the inner wall of the limiting groove 6 of the first-stage lifting seat 5. The torsion spring 9 is in a pre-torsion state under normal conditions, continuously providing the clamping arm 8 with an outward opening elastic torque, so that the clamping arm 8 remains in an outward opening state when there is no external force constraint, and the inner side wall of the clamping arm 8 abuts against the bottom wall of the limiting groove 6, forming a mechanical limit on the opening angle.

[0024] The top end face of the secondary lifting seat 2, on both the left and right sides of the mounting groove 4, is symmetrically provided with inwardly recessed contour grooves 10. The inner wall contour of the contour groove 10 perfectly matches the outer wall contour of the clamping arm 8, forming an arc-shaped inclined surface that gradually tapers inward from top to bottom. When the clamping arm 8 moves downward with the primary lifting seat 5, the outer wall of the clamping arm 8 gradually fits into the contour groove 10. The inner wall of the contour groove 10 generates a radially inward constraint reaction force on the clamping arm 8, forcing the clamping arm 8 to overcome the torsion of the torsion spring 9 and rotate inward around the hinge shaft 7 to finally form a circular clamping surface.

[0025] The first-stage lifting seat 5 has a horizontally extending locking hole 11 on its side wall. The second-stage lifting seat 2 has a locking component 12 installed inside. The locking end of the locking component 12 can extend horizontally and be inserted into the locking hole 11. After the pipeline is installed in place, the relative positions of the first-stage lifting seat 5 and the second-stage lifting seat 2 are locked to prevent the first-stage lifting seat 5 from rebounding and the clamping arm 8 from opening, thus achieving permanent fixation of the pipeline.

[0026] II. Optimal Implementation Details of Each Component 1. Two-stage lifting seat guide and anti-slip structure As a preferred embodiment, in order to ensure the straightness and stability of the lifting process of the secondary lifting seat 2, a vertically arranged guide rod 13 is fixed at the center of the bottom inner wall of the base 1. The first spring 3 is coaxially sleeved on the outside of the guide rod 13. The guide rod 13 can radially limit the compression and rebound process of the first spring 3 to avoid the spring from being compressed and deviating or becoming unstable.

[0027] Correspondingly, a vertically extending receiving groove 14 is provided at the bottom center of the secondary lifting seat 2, and the upper end of the guide rod 13 is slidably connected in the receiving groove 14. The two are fitted with a clearance to provide precise linear guidance for the vertical sliding of the secondary lifting seat 2, ensuring that there is no swaying or jamming during the lifting process of the secondary lifting seat 2, and ensuring the alignment accuracy of the locking component 12.

[0028] Furthermore, to prevent the secondary lifting seat 2 from detaching from the base 1 under the elastic force of the first spring 3, vertically extending waist-shaped anti-detachment grooves 15 are provided on the left and right side walls of the secondary lifting seat 2. Anti-detachment screws 16 are threadedly connected to the corresponding positions on the left and right side walls of the base 1. The threaded end of the anti-detachment screw 16 passes through the side wall of the base 1, extends into the mounting cavity, and is embedded in the waist-shaped anti-detachment groove 15.

[0029] When the secondary lifting seat 2 rises to its highest position under the support of the first spring 3, the rod of the anti-detachment screw 16 abuts against the lower inner wall of the waist-shaped anti-detachment groove 15, restricting the secondary lifting seat 2 from continuing to move upward; when the secondary lifting seat 2 descends, the anti-detachment screw 16 slides upward relative to the waist-shaped anti-detachment groove 15, without interfering with the normal lifting stroke, and at the same time plays an auxiliary guiding role.

[0030] 2. Single-stage lifting seat anti-slip structure As a preferred embodiment, in order to prevent the first-stage lifting seat 5 from coming off the mounting groove 4, two vertically arranged stepped anti-detachment rods 17 are symmetrically fixed at the bottom of the first-stage lifting seat 5. The lower diameter of the stepped anti-detachment rod 17 is larger than the upper diameter of the rod body, forming a stepped shaft structure that is larger at the bottom and smaller at the top.

[0031] Correspondingly, vertically extending stepped holes 18 are symmetrically provided in the secondary lifting seat 2 below the mounting groove 4. The upper part of the stepped hole 18 has a smaller diameter and the lower part has a larger diameter, forming a stepped structure that matches the stepped anti-detachment rod 17. The stepped anti-detachment rod 17 is slidably connected in the stepped hole 18. When the primary lifting seat 5 rises to the highest position, the large-diameter section at the lower end of the stepped anti-detachment rod 17 abuts against the upper step surface of the stepped hole 18, restricting the primary lifting seat 5 from moving further upward, thus achieving the anti-detachment function, and also providing auxiliary guidance for the sliding of the primary lifting seat 5.

[0032] 3. The specific structure of the locked component In a preferred embodiment, the locking assembly 12 adopts a purely mechanical inclined plane drive structure, specifically including a slider 19, a locking rod 20, and a second spring 21. A laterally extending slide groove 22 is provided inside the secondary lifting seat 2 on one side of the mounting groove 4. One end of the slide groove 22 communicates with the side wall of the mounting groove 4. The slider 19 is slidably installed within the slide groove 22 and can slide laterally left and right along the slide groove 22.

[0033] A horizontally arranged locking rod 20 is fixed on the side end face of the slider 19 facing the mounting groove 4. The axis position of the locking rod 20 corresponds to the axis position of the locking hole 11 on the side wall of the first-stage lifting seat 5. The locking rod 20 can slide laterally with the slider 19 and insert or withdraw from the locking hole 11.

[0034] The second spring 21 is horizontally installed between the side wall of the slider 19 away from the mounting groove 4 and the inner wall of the slide groove 22. Under normal conditions, the second spring 21 is in a pre-compressed state, continuously providing the slider 19 with elastic force in the direction away from the mounting groove 4, so that the locking rod 20 remains in the unlocked state retracted into the slide groove 22 when there is no external force driving it, and does not interfere with the normal lifting and lowering of the first-stage lifting seat 5.

[0035] The bottom end face of the slider 19 is provided with a first inclined surface 23, which gradually slopes upward in the direction away from the mounting groove 4 to form an inclined driving structure. Correspondingly, a vertically arranged drive rod 24 is fixed on the bottom inner wall of the base 1. A vertically penetrating clearance hole 25 is provided on the secondary lifting seat 2. The clearance hole 25 communicates with the bottom of the slide groove 22. The top end of the drive rod 24 passes through the clearance hole 25 and extends into the slide groove 22. The top end of the drive rod 24 is provided with a second inclined surface 26 that cooperates with the first inclined surface 23. The inclination angle of the second inclined surface 26 is completely matched with that of the first inclined surface 23.

[0036] When the secondary lifting seat 2 slides downward relative to the base 1, the drive rod 24 fixed on the base 1 moves upward relative to the secondary lifting seat 2. The second inclined surface 26 contacts and presses against the first inclined surface 23, converting the vertical relative motion into the lateral sliding of the slider 19. This pushes the slider 19 to overcome the elastic force of the second spring 21 and move towards the mounting groove 4, thereby causing the locking rod 20 to extend and insert into the locking hole 11, thus completing the locking of the primary lifting seat 5.

[0037] Preferably, the insertion end of the locking rod 20 is provided with a chamfer 27 to form a tapered guide structure, which can reduce the alignment accuracy requirements between the locking rod 20 and the locking hole 11. Even if there is a small positional deviation due to processing and assembly errors, it can be smoothly inserted through the inclined surface guidance of the chamfer 27, avoiding jamming or jamming, and improving the reliability of the locking action.

[0038] Preferably, when the bracket is in its initial standby state, there is a vertical travel gap between the second inclined surface 26 at the top of the drive rod 24 and the first inclined surface 23 at the bottom of the slider 19. This travel gap corresponds to a section of the empty descent travel of the secondary lifting seat 2. During this travel, the secondary lifting seat 2 descends but the locking component 12 is not triggered. This ensures that the primary lifting seat 5 is fully descended and the clamping arm 8 fully grips the pipe before the drive rod 24 contacts the slider 19 to trigger the locking action. Structurally, this strictly ensures the action sequence of "gripping first, then locking," avoiding the problem of premature locking leading to incomplete pipe clamping.

[0039] 4. Pipeline load-bearing conformal structure As a preferred embodiment, in order to improve the stability and fit of the pipeline under load, the top surface of the first-stage lifting seat 5 is provided with a first contour surface 28. The first contour surface 28 is a concave arc surface that matches the curvature of the outer wall of the pipeline, which can increase the contact area with the outer wall of the pipeline, reduce local pressure, avoid damaging the anti-corrosion layer of the pipeline, and prevent the pipeline from rolling and shifting on the support.

[0040] Furthermore, the top surface of the secondary lifting seat 2 is provided with a second contour surface 29, which is also a concave arc surface adapted to the curvature of the outer wall of the pipe. When the locking rod 20 is fully inserted into the locking hole 11 and the support is in a locked and fixed state, the first contour surface 28 and the second contour surface 29 are on the same arc surface and are flush with each other, forming a continuous and complete arc support surface, which evenly bears the vertical load of the pipe, avoids stress concentration, and improves the load-bearing capacity of the support and the stability of the pipe fixation.

[0041] III. Operating Methods and Complete Working Process Please see Figure 7 The complete working process of the pipe installation bracket for building engineering described in this invention is as follows: S1 Initial Standby Preparation The bracket is in standby mode when no pipes are installed. The first spring 3 provides upward elastic support to the secondary lifting seat 2, placing the secondary lifting seat 2 at its maximum lifting position. The anti-detachment screw 16 abuts against the lower inner wall of the waist-shaped anti-detachment groove 15, preventing the secondary lifting seat 2 from continuing to detach upward. The torque of the torsion spring 9 drives the two clamping arms 8 to rotate outward around the hinge shaft 7. The inner sidewall of the clamping arm 8 abuts against the bottom wall of the limiting groove 6 to form an opening limit. At this time, the two clamping arms 8 are in the shape of an outwardly opening trumpet, which makes it easy for the pipe to be inserted from above. Under the reaction force of the torsion spring 9 and the limiting action of the stepped anti-disengagement rod 17, the first-stage lifting seat 5 is positioned at the upper end of the mounting groove 4, and the first contour surface 28 at the top extends out of the mounting groove 4. When the locking assembly 12 is in the unlocked state, the second spring 21 pulls the slider 19 to completely retract the locking rod 20 into the slide groove 22. A set travel gap is left between the second inclined surface 26 at the top of the drive rod 24 and the first inclined surface 23 at the bottom of the slider 19.

[0042] S2 Pipe placement and clamp retraction The iron pipe to be installed is hoisted horizontally, aligned with the center of the support, and lowered so that it rests on the first contour surface 28 of the first-stage lifting seat 5. The weight of the pipe itself presses down on the first-stage lifting seat 5, causing it to slide downwards along the inner wall of the mounting groove 4.

[0043] During this process, the two clamping arms 8 move downward synchronously with the first-stage lifting seat 5. The lower end of the outer wall of the clamping arm 8 gradually contacts and adheres to the inner wall of the contour groove 10 at the top of the second-stage lifting seat 2. The converging inner wall of the contour groove 10 generates a radially inward constraint reaction force on the clamping arm 8. This reaction force is transmitted to the hinge shaft 7 through the clamping arm 8, overcoming the torque of the torsion spring 9, and forcing the clamping arm 8 to rotate inward around the hinge shaft 7 and retract. The upper ends of the two clamping arms 8 gradually approach the outer wall of the pipe.

[0044] During this stage, since the initial supporting force of the first spring 3 is much greater than the axial resistance converted from the torsion spring 9, the second-stage lifting seat 2 remains stationary, and only the first-stage lifting seat 5 slides downward relative to the second-stage lifting seat 2. The torsion spring 9 gradually twists and stores force, and the first spring 3 does not compress temporarily.

[0045] S3 First-level seating and radial clamping When the first-stage lifting seat 5 is completely lowered to the bottom end face of the mounting groove 4, the stepped anti-detachment rod 17 descends to the lower end of the stepped hole 18, the relative sliding stroke between the first-stage lifting seat 5 and the second-stage lifting seat 2 is completely completed, and the first-stage lifting seat 5 sits on the second-stage lifting seat 2.

[0046] At this time, the outer walls of the two clamping arms 8 are fully adapted and fitted to the inner wall of the contour groove 10. The contour groove 10 provides complete radial support for the clamping arms 8. The inner sides of the two clamping arms 8 enclose a complete circumferential clamping surface, which tightly wraps around the outer wall of the pipe, completing the radial clamping and positioning of the pipe and restricting the lateral displacement and rolling of the pipe.

[0047] S4 Level 2 Descent and Auto Lock-up After the first-stage lifting seat 5 is fully seated, the entire vertical load of the pipeline is transmitted to the second-stage lifting seat 2 through the first-stage lifting seat 5. The total downward force exceeds the initial support force of the first spring 3, pushing the second-stage lifting seat 2 to slide smoothly down the guide rod 13 into the base 1, and the first spring 3 is gradually compressed.

[0048] During the descent of the secondary lifting seat 2, the drive rod 24 fixed to the bottom of the base 1 moves upward relative to the secondary lifting seat 2, first eliminating the initial stroke gap; then, the second inclined surface 26 at the top of the drive rod 24 contacts and abuts against the first inclined surface 23 at the bottom of the slider 19. As the secondary lifting seat 2 continues to descend, the two inclined surfaces press against each other, converting the vertical relative motion into the lateral sliding of the slider 19. The slider 19 overcomes the elastic force of the second spring 21 and moves towards the mounting groove 4, causing the locking rod 20 to extend laterally from the slide groove 22, align with and insert into the locking hole 11 on the side wall of the primary lifting seat 5. The chamfer 27 at the end of the locking rod 20 serves as a guide for alignment, ensuring smooth insertion even with slight positional deviations and guaranteeing reliable locking action.

[0049] When the secondary lifting seat 2 descends to the set low position, the locking rod 20 is fully inserted into the locking hole 11, and the relative position of the primary lifting seat 5 and the secondary lifting seat 2 is rigidly locked. The clamping arm 8 permanently maintains a tight grip on the pipeline and will not loosen due to pipeline vibration, thermal expansion and contraction, or external disturbances. At this time, the first contour surface 28 on the top surface of the primary lifting seat 5 and the second contour surface 29 on the top surface of the secondary lifting seat 2 are flush, forming a continuous arc support surface to bear the weight of the pipeline, and the pipeline installation and fixing are completed.

[0050] IV. Pipeline Disassembly Process When it is necessary to disassemble and maintain the pipeline, the pipeline is lifted upward using hoisting equipment, and the vertical pressure of the pipeline on the primary lifting seat 5 gradually disappears. The first spring 3 begins to rebound, pushing the secondary lifting seat 2 upward. The drive rod 24 moves downward relative to the secondary lifting seat 2, and the slider 19 slides away from the mounting groove 4 under the elastic force of the second spring 21, causing the locking rod 20 to exit from the locking hole 11 and release the locking state.

[0051] As the secondary lifting seat 2 continues to rise to its initial high position, the primary lifting seat 5 slides upward relative to the secondary lifting seat 2 under the torque of the torsion spring 9. The clamping arm 8 opens outward under the drive of the torsion spring 9, returning to its initial open state, so that the pipe can be easily removed from the bracket and disassembly can be completed.

[0052] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.

4. The pipe installation bracket for building engineering according to claim 1, characterized in that, The bottom of the first-level lifting seat (5) is symmetrically fixed with a stepped anti-detachment rod (17), and the second-level lifting seat (2) is provided with a stepped hole (18), and the stepped anti-detachment rod (17) is slidably connected in the stepped hole (18).

5. A pipe installation bracket for building engineering according to claim 1, characterized in that, The end of the locking lever (20) is chamfered (27).

6. A pipe installation bracket for building engineering according to claim 1, characterized in that, The top surface of the first-stage lifting seat (5) is provided with a first contour surface (28) that mates with the outer wall of the pipe.

7. A pipe installation bracket for building engineering according to claim 6, characterized in that, The top surface of the secondary lifting seat (2) is provided with a second contour surface (29) that cooperates with the outer wall of the pipe. When the locking hole (11) cooperates with the locking rod (20), the first contour surface (28) and the second contour surface (29) are flush.

8. A method for operating a pipe installation bracket for building engineering as described in any one of claims 1-7, characterized in that, Includes the following steps: S1: Initial standby preparation: The bracket is in standby state without pipes installed. The first spring (3) elastically supports the second-stage lifting seat (2) to the upper limit position. The spring force of the torsion spring (9) drives the clamping arm (8) to open outward. The top of the first-stage lifting seat (5) extends out of the mounting slot (4). The locking component (12) is in the unlocked state. S2: Pipe placement and clamp arm retraction: Place the pipe to be installed horizontally on the top surface of the first-stage lifting seat (5). The pipe presses down on the first-stage lifting seat (5) by its own weight, so that the first-stage lifting seat (5) slides into the installation groove (4) along the Z-axis. The clamp arm (8) moves down synchronously with the first-stage lifting seat (5) and retracts inward under the constraint of the inner wall of the contour groove (10) against the torque of the torsion spring (9). S3: First-level seat and radial clamping: When the first-level lifting seat (5) is fully inserted into the mounting groove (4), the outer walls of the two clamping arms (8) are fully adapted and fitted to the contour groove (10), and the two clamping arms (8) enclose and clamp the outer wall of the pipe to complete the radial clamping and positioning of the pipe. S4: Secondary descent and automatic locking: The pipeline continues to press down under its own gravity, and the load is transmitted to the secondary lifting seat (2) and drives the secondary lifting seat (2) to overcome the elastic force of the first spring (3) and slide down into the base (1). The drive rod (24) fixed at the bottom of the base (1) moves upward relative to the secondary lifting seat (2). Through the cooperation of the inclined surfaces of the first inclined surface (23) and the second inclined surface (26), the slider (19) is pushed to slide laterally, so that the locking rod (20) is inserted into the locking hole (11) on the side wall of the primary lifting seat (5), and the relative position of the primary lifting seat (5) and the secondary lifting seat (2) is locked, and the pipeline installation is completed.
