Description

Technical Field

[0001] The present invention relates to the technical field of building construction, in particular to an adjustable pipeline support and hanger and a construction method thereof. Background Art

[0002] During pipeline installation, supports and hangers play a crucial role in suspending the pipes. Traditionally, pipe suspension in concrete construction involves using expansion bolts to secure the supports and hangers. This involves drilling holes into the concrete structure, inserting expansion bolts, and then securing the prefabricated supports and hangers to the wall or floor.

[0003] Expansion bolt connections require drilling holes into the structure's surface, making them difficult to apply to specialized construction applications (e.g., steel structures). Furthermore, if pipe sizes vary between construction projects, supports and hangers must be customized accordingly, rather than reusing the same supports and hangers used for the previous project. Therefore, the traditional construction method of securing supports and hangers to structures with expansion bolts is less applicable and inefficient. Summary of the Invention

[0035] See again Figure 1 The adjustable pipe support and hanger provided in an embodiment of the present invention includes a steel beam 100, a fixture 200, a connecting assembly 300 and a hanger 400; the top of the fixture 200 is connected to the inner surface of the lower flange of the steel beam 100, and the bottom of the fixture 200 is detachably connected to the outer surface of the lower flange of the steel beam 100 through the connecting assembly 300; the hanger 400 is detachably connected to the fixture 200, and is parallel to the web of the steel beam 100.

[0036] In this embodiment, the adjustable pipe support and hanger is used in the field of prefabricated steel structures. Compared with the traditional method of hanging pipes by fixing with expansion bolts, the adjustable pipe support and hanger in this embodiment can clamp the fixture 200 to the inner and outer surfaces of the lower flange of the steel beam 100 through the connection assembly 300. Therefore, the clamping force required for construction can be met without pre-embedding or drilling holes in the structure, thus avoiding damage to the steel structure and greatly improving the adaptability of the support and hanger in prefabricated steel structures.

[0037] In addition, since the hanger 400 in this embodiment is detachably connected to the fixture 200, the connection method between the hanger 400 and the fixture 200 can be flexibly adjusted according to factors such as the model of the steel beam 100, the size of the pipe to be suspended, and the installation height of the pipe to be suspended, thereby greatly improving construction efficiency. For example, for small-sized pipes, the first hanger 410 is selected, the hanger 400 is inserted into the hanger through hole of the connecting bolt 310 on the side end face of the fixture 200, and then the pipe to be suspended is connected to the bottom of the first hanger 410, thereby meeting the suspension requirements for small-sized pipes. For large-sized pipes, the second hanger 420 is selected, the square steel is inserted into the rectangular hole 240 of the fixture 200, the second hanger 420 is inserted into the third hanger through hole on the square steel, and the pipe to be suspended is fixed at the bottom of the second hanger 420, thereby meeting the suspension requirements for large-sized pipes.

[0038] Specifically, the steel beam 100 serves as the basic load-bearing component of the entire support and hanger, and is usually made of high-strength steel such as Q235B or Q345B, and has good compression and bending resistance. The cross-sectional shape of the steel beam 100 is an I-shape, which includes an upper flange, a lower flange, and a web. The upper flange can be connected to other components in the building structure to provide a stable support; the lower flange is the key part of the connection fixture 200; the web is between the upper and lower flanges and its two ends are vertically connected to the upper and lower flanges respectively, thereby improving its ability to resist lateral deformation. The selection of high-strength steel ensures that the steel beam 100 can withstand the weight of the pipeline and itself and external loads, thereby ensuring the safety of the support and hanger.

[0039] The clamp 200 is a C-shaped steel, the top of which is placed on the inner surface of the lower flange of the steel beam 100, and the end face of the side facing the steel beam 100 is abutted against the end of the lower flange of the steel beam 100. A threaded circular hole 250 is provided at the bottom. The fastening bolt 320 in the connecting assembly 300 is passed through the threaded circular hole 250 and is continuously screwed into the outer surface of the lower flange of the steel beam 100 until it abuts against the outer surface of the lower flange of the steel beam 100, so as to achieve the fastening connection of the clamp 200 to the lower flange of the steel beam 100.

[0040] The top of the fixture 200 is tightly connected to the inner surface of the steel beam 100, and its bottom abuts against the outer surface of the lower flange of the steel beam 100 via fastening bolts 320, allowing the fixture 200 to be securely fixed to the steel beam 100, preventing displacement during pipeline operation. Furthermore, by adjusting the length of the fastening bolts 320 in the connection assembly 300 toward the outer surface of the lower flange of the steel beam 100, it can be adapted to connect to lower flanges of varying thicknesses. Therefore, this arrangement is suitable for steel beams 100 of varying sizes, enhancing the versatility of the adjustable pipe support.

[0041] It should be noted that, according to the same setting method as mentioned above, the adjustable pipe support and hanger in this embodiment can be set on one side of the lower flange of the steel beam 100 according to construction needs, or the adjustable pipe support and hanger in this embodiment can be set on both opposite sides of the lower flange of the steel beam 100.

[0042] The hanger rod 400 is typically made of round steel or seamless steel pipe, which has high tensile strength. One end of the hanger rod 400 is externally threaded. The end of the fixture 200 facing away from the steel beam 100 is secured with a bolt. This bolt has a hanger rod through-hole. After the hanger rod 400 is inserted through the through-hole, a nut is fitted onto the top of the hanger rod 400 to secure it to the bolt, enabling detachable installation of the hanger rod 400 and the fixture 200. The other end can be equipped with a connecting structure, such as a clamp or other connector for connecting to a pipe, as needed.

[0043] In one embodiment, a hanger rod 400 of appropriate length can be selected based on the installation height of the pipeline to meet the requirements of pipeline installation at different heights. For example, if the pipeline installation location is closer to the lower flange of the steel beam 100 (i.e., the pipeline needs to be installed at a higher position), a shorter hanger rod 400 is selected. After the fixture 200 is fixed to the lower flange of the steel beam 100 and the hanger rod 400 is installed and fixed to the fixture 200, the pipeline to be suspended and installed is fixed to the bottom of the hanger rod 400, thus achieving the requirement of installing the pipeline at a higher height. Conversely, if the pipeline installation location is farther from the lower flange of the steel beam 100 (i.e., the pipeline needs to be installed at a lower position), a longer hanger rod 400 is selected to achieve the requirement of installing the pipeline at a lower height.

[0044] In another embodiment, in order to meet the requirements of pipe installation at different heights, the hanger 400 can be set to a telescopic sleeve. For example, the hanger 400 is composed of two layers of inner and outer sleeves, and the inner sleeve can slide inside the outer sleeve. The outer sleeve is inserted into the hanger through hole on the fixture 200 to form a detachable connection with the fixture 200, and the bottom of the inner sleeve is connected to the pipe to be suspended and installed. A plurality of positioning holes are provided on the inner sleeve and the outer sleeve at intervals along the axial direction, and positioning pins are used to pass through the corresponding positioning holes to fix the relative positions of the inner and outer sleeves to achieve the adjustment of the length of the hanger 400. In order to prevent the inner sleeve from shaking during the sliding process, a guide groove and a guide block can be provided between the inner and outer sleeves to ensure the stability of the telescopic movement.

[0045] In this embodiment, the hanger 400 is made of high-strength material, which can effectively withstand the vertical load of the pipeline. The detachable connection method facilitates the installation and removal of the pipeline, facilitating construction and maintenance. At the same time, the adjustable pipe support and hanger can adapt to the installation requirements of pipelines at different heights, improving the versatility and applicability of the adjustable pipe support and hanger.

[0046] In one embodiment, if Figure 1 as well as Figure 2 As shown, the fixture 200 includes a vertical portion 210, a first horizontal portion 220 and a second horizontal portion 230; the first horizontal portion 220 and the second horizontal portion 230 are both vertically connected to the end surface of the vertical portion 210 facing the steel beam 100, wherein the first horizontal portion 220 is adjacent to the top of the vertical portion 210, and the second horizontal portion 230 is adjacent to the bottom of the vertical portion 210; the inner surface of the first horizontal portion 220 is connected to the inner surface of the lower flange of the steel beam 100.

[0047] In this embodiment, vertical portion 210 serves as the main support structure of fixture 200, and its specific thickness is determined based on the load-bearing capacity requirements of fixture 200. Using steel plates of appropriate thickness to construct vertical portion 210 can avoid material waste and reduce costs while meeting load-bearing requirements. Its height is designed based on the spatial distance from the lower flange of steel beam 100 to the pipeline installation location, ensuring sufficient space for installing hanger 400 and connecting the pipeline. By determining the appropriate height, the space required for installing hanger 400 and connecting the pipeline is guaranteed, ensuring the rationality of the overall structure of the support and hanger.

[0048] The first horizontal portion 220 and the second horizontal portion 230 have identical dimensions (length, thickness, and width) and materials (for example, Q355B low-alloy, high-strength structural steel), and both are rectangular plates. These identical dimensions, materials, and shapes ensure that the first horizontal portion 220 (connecting to the inner surface of the steel beam 100) and the second horizontal portion 230 (connecting to the outer surface of the steel beam 100) form a symmetrical load-bearing structure, avoiding stress concentration caused by dimensional differences. For example, when hoisting a pipeline, the upper and lower horizontal portions can evenly transfer load to the vertical portion 210, thereby improving overall stability.

[0049] As for the specific setting, in one embodiment, the first horizontal portion 220 and the second horizontal portion 230 are both vertically arranged on the end surface of the vertical portion 210 facing the lower flange of the steel beam 100, wherein the first horizontal portion 220 is located above the second horizontal portion 230 (more specifically, the first horizontal portion 220 is adjacent to the bottom of the vertical portion 210, and the second horizontal portion 230 is adjacent to the bottom of the vertical portion 210). The three can be formed as one piece during prefabrication in the factory.

[0050] In another embodiment, the first horizontal portion 220 and the second horizontal portion 230 can also be fixedly connected to the vertical portion 210 by welding. Specifically, a welding groove for fixing the first horizontal portion 220 and the second horizontal portion 230 is provided on the end face of the vertical portion 210 facing the steel beam 100. The angle of the groove is set to 45°-60°, for example, to ensure the welding quality. The welding groove at a specific angle ensures the welding quality with the first and second horizontal portions, so that the various parts of the fixture 200 are firmly connected. If welding is used for connection, double-sided fillet welds are used, and the weld height is not less than 8 mm, so as to ensure that the connection strength required for construction can be met.

[0051] In one embodiment, if Figure 2 as well as Figure 3 As shown, the fixture 200 further includes a rectangular hole 240 and a threaded circular hole 250 ; the rectangular hole 240 is disposed in the middle of the vertical portion 210 ; and the threaded circular hole 250 is disposed in the second horizontal portion 230 .

[0052] In this embodiment, the rectangular holes 240 are compatible with the square steel tubes 500. For the hanging of large-sized pipes, the fixtures 200 can be first fixed to the two ends of the lower flange of the steel beam 100, and then the square steel tubes 500 can be sequentially inserted from left to right (or from right to left) into the rectangular holes 240 on the fixtures 200 at the opposite ends of the lower flange of the steel beam 100. The horizontality and verticality of the square steel tubes 500 are adjusted to ensure that the central axis of the third hanger hole at the end of the square steel tube 500 is vertical. Subsequently, the second hanger 420 is inserted from top to bottom into the third hanger hole and fixed at a preset height by fitting with a nut.

[0053] In addition, the first preset distance between the center of the rectangular hole 240 and the lower surface of the first horizontal portion 220 is greater than the second preset distance between the outer surface of the lower flange of the steel beam 100 and the lower surface of the first horizontal portion 220, providing sufficient vertical space for the square steel to pass through the rectangular hole 240, avoiding interference between the square steel and the lower flange of the steel beam 100 due to insufficient space, and greatly reducing the difficulty of alignment during installation and the risk of mechanical collision.

[0054] Threaded circular holes 250 are provided in the second horizontal portion 230, with their central axis perpendicular to the lower flange of the steel beam 100. These holes are used to mate with the fastening bolts 320 to clamp the fixture 200 to the upper and lower surfaces of the lower flange of the steel beam 100. This vertical arrangement allows the axial force of the fastening bolts 320 to act directly on the upper and lower surfaces of the lower flange of the steel beam 100. This minimizes the force transmission path and ensures a clear direction. This avoids the decomposition of the clamping force (such as the generation of lateral force components) caused by angular deviation, thus ensuring the stability of the connection between the fixture 200 and the steel beam 100.

[0055] In one embodiment, if Figures 1 to 5 As shown, the connecting assembly 300 includes a connecting bolt 310 and a fastening bolt 320; the connecting bolt 310 is arranged on the end face of the vertical portion 210 facing away from the steel beam 100; the fastening bolt 320 is passed through the threaded circular hole 250 and abuts against the outer surface of the lower flange of the steel beam 100.

[0056] In this embodiment, at least one connecting bolt 310 is arranged on the end face of the vertical portion 210 facing away from the steel beam 100. After the hanger 400 is detachably connected to the connecting bolt 310, the pipe to be suspended is fixed at the bottom of the hanger 400. The hanger 400 can be adjusted to meet the installation requirements of pipes at different heights.

[0057] After the fastening bolt 320 is passed through the threaded circular hole 250, it is continuously screwed in toward the outer surface of the lower flange of the steel beam 100 until the fastening bolt 320 abuts against the outer surface of the lower flange of the steel beam 100. By continuously screwing in the fastening bolt 320 until it abuts against the lower flange of the steel beam 100, it is ensured that the clamp 200 and the steel beam 100 are tightly fitted, and the axial force of the bolt is used to form a reliable clamping force to avoid shaking or displacement caused by the gap. In addition, a gasket and a fastening nut can be set on the fastening bolt 320 on the side of the second horizontal portion 230 facing away from the outer surface of the lower flange of the steel beam 100 to reinforce the fastening bolt 320. The combination of the gasket and the fastening nut can effectively disperse the pressure on the bolt head and prevent the bolt from loosening under vibration or long-term load, and is particularly suitable for dynamic working conditions (such as the slight vibration scenario generated when transporting suspended pipes).

[0058] In one embodiment, if Figure 1 、 Figure 2 、 Figure 3 as well as Figure 5 As shown, the connecting bolt 310 includes a first bolt 311; the first bolt 311 is vertically arranged on the end face of the vertical portion 210 facing away from the steel beam 100, and is adjacent to the top of the vertical portion 210; the first bolt 311 is provided with a first hanger through hole, and the first hanger through hole is parallel to the vertical portion 210.

[0059] In this embodiment, two connecting bolts 310 (e.g., high-strength bolts) are vertically spaced apart on the end surface of the vertical portion 210 facing away from the steel beam 100. The connecting bolt 310 adjacent to the top of the vertical portion 210 is a first bolt 311. This arrangement adjacent to the top of the vertical portion 210 moves the connection point of the suspension rod 400 upward, shortening the vertical distance between the center of gravity of the suspension rod 400 and the fixture 200, reducing the lever torque during lifting, and lowering the risk of the vertical portion 210 tipping over or bending.

[0060] The first bolt 311 is provided with a first hanger through hole along the vertical axis, that is, the vertical center axis of the first hanger through hole is parallel to the vertical portion 210. The first hanger through hole is used to adapt to the first hanger 410. During construction, the first hanger 410 is passed through the first hanger through hole. In addition, the aperture of the first hanger through hole is slightly larger than the diameter of the first hanger 410 (the tolerance error is controlled at 0.2mm). Firstly, it is conducive to the first hanger 410 being able to pass through the first hanger through hole smoothly. Secondly, it enhances the space for the first hanger 410 to move under complex working conditions, avoiding installation restrictions caused by the small aperture of the first hanger through hole.

[0061] In one embodiment, if Figure 2 as well as Figure 3 As shown, the connecting bolt 310 also includes a second bolt 312; the second bolt 312 is vertically arranged on the end face of the vertical portion 210 facing away from the steel beam 100, and is adjacent to the bottom of the vertical portion 210; the second bolt 312 is provided with a second hanger through hole, and the second hanger through hole is vertically coaxially arranged with the first hanger through hole.

[0062] In this embodiment, the second bolt 312 has the same diameter as the first bolt 311 and is located directly below the first bolt 311, adjacent to the bottom of the vertical portion 210. Furthermore, the second hanger rod through-hole defined in the second bolt 312 is vertically coaxial with the first hanger rod through-hole defined in the first bolt 311. This dual-bolt structure splits the tensile force of the hanger rod 400 into two points, with the load borne by a single connecting bolt 310 accounting for approximately 50% of the total load. This prevents single-point overload or deformation of the vertical portion 210 due to localized overload.

[0063] In one embodiment, if Figure 1As shown, the suspension rod 400 includes a first suspension rod 410; the first suspension rod 410 is sequentially inserted into the first suspension rod through hole and the second suspension rod through hole.

[0064] In this embodiment, the first suspension rod 410 is used to suspend small-sized pipes. Its shape is compatible with the first suspension rod through hole and the second suspension rod through hole (for example, it is made of round steel or square steel), and its diameter or cross-sectional size needs to be compatible with the aperture of the first suspension rod through hole and the second suspension rod through hole.

[0065] During the specific construction, the first hanger 410 first passes through the first hanger through hole of the first bolt 311 at the top, and then passes downward through the second hanger through hole of the second bolt 312 at the bottom, forming a "top-down" through-type connection. The top of the first hanger 410 (that is, the end of one side of the first hanger 410 that fits into the first hanger through hole) is processed with threads (or welded rings) for installing nuts, washers or hooks to ensure effective transmission of force during hoisting and to fix the first hanger 410 to the first connecting nut. After completing the assembly of the first hanger 410 and the fixture 200, the pipe to be suspended can be fixed at the bottom of the first hanger 410, thereby meeting the hoisting and suspension requirements of the pipe.

[0066] In one embodiment, if Figure 5 As shown, the steel beam 100 further includes a square steel tube 500. The square steel tube 500 is inserted into the rectangular hole 240 and is adjacent to the outer surface of the lower flange of the steel beam 100. A third hanger hole is vertically defined at the end of the square steel tube 500. The hanger 400 includes a second hanger 420, which is inserted into the third hanger hole.

[0067] In this embodiment, the cross-sectional dimensions of the square steel tube 500 need to be smaller than the inner diameter of the rectangular hole 240. For example, a gap of 2-5 mm should be reserved to facilitate insertion. Avoiding excessively large gaps allows the outer wall of the square steel tube 500 to fit closely with the edge of the rectangular hole 240, forming a stable lateral support. Specifically, after the square steel tube 500 is inserted into the rectangular hole 240, it is moved axially to abut the outer surface of the lower flange of the steel beam 100. The geometric constraints of the rectangular hole 240 limit the vertical displacement of the square steel tube 500. At the same time, the horizontal end surface of the square steel tube 500 contacts the lower flange of the steel beam 100, forming a "surface support" structure.

[0068] A third hanger through hole is opened at each end of the square steel tube 500 (the two side ends along the length direction), and the third hanger through hole passes through in the vertical direction. The aperture of the third hanger through hole is adapted to the diameter of the second hanger 420 so that the second hanger 420 can pass through the third hanger through hole (for example, the diameter of the second hanger 420 is 20 mm, and the aperture of the third hanger through hole is 22 mm).

[0069] The second hanger 420 is a rod (such as round steel, chain or wire rope) arranged in the vertical direction. Specifically, after the fixture 200 is connected and fixed to the opposite ends of the lower flange of the steel beam 100, the square steel pipe 500 is sequentially inserted into the rectangular holes 240 on the two fixtures 200 in order from left to right (or from right to left). Subsequently, the horizontality and verticality of the square steel pipe 500 are adjusted so that the central axis of the third hanger through hole at its end is vertically perpendicular to the outer surface of the lower flange of the steel beam 100. The third hanger 400 is then inserted into the third hanger through hole from top to bottom, and a nut is mounted on the second hanger 420 on the side of the third hanger through hole facing the lower flange of the steel beam 100, so that the height of the second hanger 420 remains relatively fixed. Finally, fix the pipe to be hoisted at the bottom of the second hoist rod 420 (the bottom of the second hoist rod 420 is also the end of the second hoist rod 420 away from the lower flange of the steel beam 100), and the pipe can be hoisted or suspended.

[0070] like Figure 6 As shown, an embodiment of the present invention further provides a construction method of an adjustable pipe support and hanger, which is applied to the adjustable pipe support and hanger in any of the aforementioned embodiments, and the method includes:

[0071] S1. Adjust the horizontality and verticality of the steel beam and place the first horizontal part of the fixture on the inner surface of the lower flange of the steel beam.

[0072] In this embodiment, a high-precision level and theodolite can be used to measure the steel beam 100. The level measures the horizontality of the steel beam 100 and controls its deviation within ±2mm / m; the theodolite measures the verticality of the steel beam 100 and controls the deviation within ±3mm / m. After the measurement is completed, the first horizontal portion 220 of the fixture 200 can be placed on the inner surface of the lower flange of the steel beam 100, while the vertical portion 210 of the fixture 200 abuts against the end of the lower flange of the steel beam 100. High-precision measurement and leveling ensure the accuracy of the installation of the steel beam 100, laying a good foundation for the subsequent installation of supports and hangers and pipelines, and avoiding problems such as tilting and stress concentration after pipeline installation due to deviation of the steel beam 100.

[0073] S2. Screw the fastening bolts in the connection assembly into the threaded circular holes at the bottom of the fixture until they abut against the outer surface of the lower flange of the steel beam.

[0074] In this embodiment, a high-strength fastening bolt 320 (such as grade 8.8 or grade 10.9) that matches the specifications of the threaded circular hole 250 is selected. The length of the fastening bolt 320 is determined according to the thickness of the fixture 200 and the thickness of the lower flange of the steel beam 100 to ensure that the fastening bolt 320 has sufficient fastening length after being screwed in. Before screwing in the fastening bolt 320, apply thread locking agent on the surface of the fastening bolt 320 to prevent the fastening bolt 320 from loosening under a vibration environment. Use an electric wrench to tighten the fastening bolt 320. The torque value of the electric wrench can be set to 60-100 N·m (adjusted according to the bolt specifications) to ensure that the bolt tightening force is uniform and meets the design requirements. After tightening, use a feeler gauge to check the fit between the head of the fastening bolt 320 and the surface of the second horizontal portion 230 of the fixture 200. The gap does not exceed 0.1mm.

[0075] The use of high-strength bolts and threadlocker effectively enhances the connection between fixture 200 and the outer surface of the lower flange of steel beam 100, improving the vibration resistance of the adjustable pipe support and hanger. This prevents loosening of fastening bolts 320 caused by vibration during pipeline operation, ensuring the stability of the adjustable pipe support and hanger. The use of an electric wrench improves installation efficiency and precisely controls torque to avoid overtightening or undertightening bolts, ensuring connection quality.

[0076] S3. If the suspended object is a small-sized pipe, vertically pass the first suspension rod through the first suspension rod through hole and the second suspension rod through hole in sequence, and fix the first suspension rod with the first suspension rod nut.

[0077] In this embodiment, the first hanger 410 can be made of round steel with a diameter of 12-16 mm, and the surface is hot-dip galvanized to prevent rust. The hot-dip galvanized hanger 400 has improved corrosion resistance and extended service life. The diameter of the second hanger through hole is the same as the diameter of the first hanger through hole, and the diameters of the first hanger through hole and the second hanger through hole are both 1-2 mm larger than the diameter of the hanger 400, ensuring that the hanger 400 can pass through smoothly. During installation, first pass the first hanger 410 through the first hanger through hole, install a gasket and the first hanger 410 nut above the fixture 200, then continue to pass the first hanger 410 through the second hanger through hole, and install a gasket and a nut (i.e., the first hanger nut) that matches the first hanger 410 below the fixture 200. Use a wrench to tighten the nut, and use a symmetrical tightening method during the tightening process to ensure that the hanger 400 is evenly stressed. The rationally designed through-hole dimensions facilitate installation of the hanger rod 400. Furthermore, the symmetrical tightening of the nuts ensures vertical force on the hanger rod 400, preventing tilt and impacting pipeline stability. By adjusting the relative positions of the upper and lower nuts that mate with the first hanger rod 410 according to the design elevation, the height of the hanger rod 400 can be adjusted to within ±3mm. This precise control of the hanger rod 400 height ensures that the elevation of small-sized pipelines meets design requirements after installation, satisfying the operational needs of the pipeline system.

[0078] S4. If the suspended object is a large-sized pipe, insert the square steel pipe horizontally into the rectangular hole in the vertical part of the fixture, adjust the horizontal position of the square steel pipe to the target point, and insert the second suspension rod into the third suspension rod through-hole at the end of the square steel pipe. Secure the second suspension rod with the second suspension rod nut.

[0079] In this embodiment, the square steel tube 500 is preferably a Q235B square steel tube 500, and its length is determined according to the span and installation space of the large-sized pipeline (for example, the length is 80-100mm). Selecting a square steel tube 500 of appropriate specifications can effectively bear the weight of the large-sized pipeline and ensure the strength of the support bracket. Before inserting the square steel tube 500, apply lubricant (such as butter) to the inner wall of the rectangular hole 240 to facilitate the insertion and adjustment of the square steel tube 500. The use of lubricant facilitates the installation and adjustment of the square steel tube 500 and improves construction efficiency. After inserting the square steel tube 500, use a spirit level and a steel tape measure to measure the horizontal position of the square steel tube 500, and calibrate its horizontal position so that its deviation is controlled within ±5mm.

[0080] In the factory, a third hanger through hole with an inner diameter 1-2 mm larger than the outer diameter of the second hanger 420 is prefabricated. The position of the third hanger through hole is preset according to actual construction needs and is usually located in the area adjacent to the end of the square steel pipe 500. When installing the second hanger 420, gaskets and nuts that match the second hanger 420 (also known as second hanger nuts) are installed at the upper and lower ends of the square steel pipe 500, respectively. Use a socket wrench to tighten the nuts, adjust the second hanger nuts according to the design elevation, and control the height adjustment accuracy within ±5 mm. Accurately measure and control the horizontal position of the square steel pipe 500 and the height of the second hanger 420 to ensure that the large-size pipeline is accurately positioned after installation, meet the installation accuracy requirements of the pipeline system, and ensure that the pipeline is evenly stressed and operates stably.

[0081] S5. Fix the pipeline at the bottom end of the hanger, and adjust the first hanger nut or the second hanger nut to adjust the pipeline elevation, or adjust the horizontal position of the square steel pipe to adjust the horizontality of the pipeline.

[0082] In this embodiment, for small-sized pipes, a pipe clamp is used to fix the pipe to the bottom end of the first hanger 410, and a rubber pad is added between the clamp and the pipe to prevent damage to the pipe surface and to reduce vibration. The use of the rubber pad protects the pipe surface and also reduces vibration, reducing the transmission of vibration during pipe operation. For large-sized pipes, the pipe can be fixed to the connector at the bottom end of the second hanger 420 by welding or flange connection. Different pipe fixing methods are suitable for pipes of different sizes, ensuring the firmness of the connection between the pipe and the hanger 400.

[0083] When adjusting the first or second hanger nut, use a height gauge to measure the pipe elevation in real time, adjusting the pipe elevation by no more than 5mm at a time to gradually adjust the pipe elevation to the designed value. When adjusting the horizontal position of the square steel pipe 500, use a laser level for positioning. Fine-tune the pipe horizontality by placing a wedge-shaped pad between the square steel pipe 500 and the fixture 200, thereby controlling the pipe horizontal deviation to within ±2mm / m. This precise elevation and level adjustment method ensures that the pipeline installation meets design requirements, improves the installation quality and operational safety of the pipeline system, and reduces the risk of pipeline leakage and stress damage caused by installation deviations.
