Description

Technical Field

[0001] This utility model relates to the field of electromechanical installation technology in engineering construction, specifically to a multi-pipe channel steel welded load-bearing support and hanger that ensures the horizontality of the crossarm. Background Technology

[0002] Pipe supports are core load-bearing components for overhead piping systems (such as air ducts, water pipes, and process piping) in industrial and civil buildings. Their levelness and structural stability directly determine the operational safety and service life of the piping system. With the widespread application of liquid cooling technology and chilled water systems in data centers, the density of pipe laying has increased, placing higher demands on the "multi-pipe compatibility" and "crossarm levelness" of pipe supports.

[0003] When the existing support and hanger have inconsistent models of boom and crossbeam channel steel, the following key issues exist: Connection method defects: Bolted or special fastener connections require precise manual operation, resulting in low installation efficiency, high cost, and potential safety hazards due to loosening over long-term use; Levelness is difficult to guarantee: In traditional lap welding or bevel welding, the bevel angle between the boom and the crossarm cannot be precisely controlled, resulting in a large error in the levelness of the crossarm, which in turn leads to uneven stress on the pipeline; Poor compatibility with multiple pipes: Most pipe supports are only compatible with single pipes, which makes it difficult to meet the needs of parallel laying of multiple pipes in scenarios such as data centers; Insufficient structural strength: Angled welding reduces the weld area, and some designs cut the side ribs of the boom, resulting in a decrease in the overall load-bearing capacity of the support. Therefore, a multi-pipe channel steel welded load-bearing support is proposed to ensure the horizontality of the crossbeam. Utility Model Content

[0004] In view of this, the present invention provides a multi-pipe channel steel welded load-bearing support and hanger to ensure the horizontality of the crossarm, aiming to solve the problems of poor horizontality, weak compatibility with multiple pipes, complex construction and insufficient strength of existing supports and hangers, and to achieve the usage requirements of "quick installation, accurate horizontality, multi-pipe compatibility and long-term stability".

[0005] The technical solution of this utility model embodiment is implemented as follows: A multi-pipe channel steel welded load-bearing support for ensuring the horizontality of the crossbeam includes a boom assembly, a horizontal channel steel crossbeam, a fixing assembly and pipe clamps disposed on the side of the boom assembly. The fixing assembly includes a welded fixing steel plate, which is fixedly connected to the structural beam by expansion bolts. The boom assembly includes a first channel steel vertical boom, which is welded to the welded fixing steel plate. The back plate and one-sided rib plate of the first channel steel vertical boom are cut off at the connection between the left and right first channel steel vertical booms and the horizontal channel steel crossbeam, and the height of the cut part is consistent with the height of the horizontal channel steel crossbeam. The horizontal channel steel crossbeam and the first channel steel vertical boom are welded together. The pipe clamps are located on the upper part of the horizontal channel steel crossbeam.

[0006] A further preferred embodiment: the welding and fixing steel plate has an elongated slotted hole for adjusting the fixing position.

[0007] A further preferred embodiment: the upper rib of the horizontal channel steel crossarm is provided with a pipe clamp connection hole, and the pipe clamp is fixed to the horizontal channel steel crossarm by bolts passing through the pipe clamp connection hole.

[0008] A further preferred embodiment: the boom assembly further includes a channel steel telescopic boom, which includes a first channel steel, a second channel steel, a sliding block, an adjusting bolt, a second channel steel vertical boom, and a connecting plate.

[0009] A further preferred embodiment: the back sides of the first channel steel and the second channel steel are fitted together, and the back sides of the first channel steel and the second channel steel are provided with through slots for the adjusting bolt to pass through, and the other end of the adjusting bolt is threadedly connected to a sliding block.

[0010] Further preferred: the fixing assembly further includes a horizontal fixing plate and reinforcing ribs, the boom assembly includes a second channel steel vertical boom and a connecting plate, the bottom of the horizontal fixing plate is connected to the top two sides of the second channel steel vertical boom through reinforcing ribs, and the bottom of the opposite sides of the two sets of second channel steel vertical booms are welded to the horizontal channel steel crossarm through connecting plates.

[0013] This utility model has the following beneficial effects: 1. This utility model, through the design of "the height of the boom cutting is consistent with the height of the crossarm", combined with the welding fixing method, avoids the angle error of traditional oblique welding, ensures that the horizontality of the crossarm meets the engineering requirements after installation, and reduces the risk of uneven stress on the pipeline; 2. This utility model significantly improves the load-bearing capacity and deformation resistance of the support frame by retaining the side ribs of the vertical boom of the channel steel and extending the weld length between the boom and the crossbeam, thus meeting the long-term load-bearing requirements of scenarios such as data centers. 3.

[0018] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive. Embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0019] Example 1 like Figure 1 As shown, this utility model embodiment provides a multi-pipe channel steel welded load-bearing support for ensuring the horizontality of the crossbeam, including a boom assembly 20, a horizontal channel steel crossbeam 30, a fixing assembly 10 disposed on the side of the boom assembly 20, and pipe clamps 40. The fixing assembly 10 includes a welded fixing steel plate 101, which is fixedly connected to the structural beam by expansion bolts. The boom assembly 20 includes a first channel steel vertical boom 201, which is welded to the welded fixing steel plate 101. The back plate and one-sided rib plate 2011 of the first channel steel vertical boom 201 are cut off at the connection between the left and right first channel steel vertical booms 201 and the horizontal channel steel crossbeam 30, and the height of the cut part is consistent with the height of the horizontal channel steel crossbeam 30. The horizontal channel steel crossbeam 30 and the first channel steel vertical boom 201 are welded together. The pipe clamps 40 are located on the upper part of the horizontal channel steel crossbeam 30.

[0020] In this embodiment, specifically: the welding and fixing steel plate 101 is provided with an elongated slotted hole 1011 for adjusting the fixing position.

[0021] In this embodiment, specifically: the upper rib plate of the horizontal channel steel crossbeam 30 is provided with a pipe clamp connection hole, and the pipe clamp 40 is fixed to the horizontal channel steel crossbeam 30 by bolts passing through the pipe clamp connection hole.

[0022] The welded fixing steel plate 101 is made of rectangular steel plate with an elongated slotted hole 1011 (20-30mm long and 8-12mm wide) on its surface. Expansion bolts are passed through the welded fixing steel plate 101 and fixed to the building structure beam. The position of the welded fixing steel plate 101 can be finely adjusted during installation to ensure precise connection between the boom and the crossbeam. The welded fixing steel plate 101 is fully welded to the side of the first channel steel vertical boom 201 to ensure the vertical stability of the boom. The first channel steel vertical boom 201 is made of hot-rolled or cold-bent channel steel. The boom length H is determined according to the pipeline design elevation. At the connection between the boom and the horizontal channel steel crossarm (lower left and lower right sides), the back plate and one-sided rib plate 2011 of the boom are cut off (the other side rib plate is retained). The height of the cut part is completely consistent with the height of the horizontal channel steel crossarm to ensure that the crossarm and the boom can fit precisely when they are connected, and to avoid the crossarm tilting due to height deviation. The horizontal channel steel crossarm 30 is made of hot-rolled or cold-formed channel steel, and its specifications are not smaller than those of the vertical channel steel boom (e.g., the boom is made of 10# channel steel and the crossarm is made of 12# channel steel). The length L of the crossarm is determined according to the diameter and quantity of the pipe. Pipe clamp connection holes (the hole diameter matches the pipe clamp bolts) are pre-set on the upper rib plate of the crossarm for fixing the pipe clamps. First, fix the welding and fixing steel plate 101 to the structural beam, and then weld the first channel steel vertical boom 201 to the welding and fixing steel plate 101; then align the horizontal channel steel crossbeam 30 with the cut part of the first channel steel vertical boom 201, and connect them by full welding (the weld length matches the cut height to improve the connection strength); after the pipeline is hoisted into place, fix the pipeline clamp 40 to the crossbeam by passing bolts through the pipe clamp connection hole, and install one or more pipe clamps according to the number of pipelines.

[0023] In this embodiment, the horizontality error of the crossarm after the support and hanger is 0.8mm / m, which meets the high precision requirements of data center pipeline installation; two pipe clamps stably fix two DN80 pipes, and no pipe displacement or support deformation has occurred during long-term operation; the welded connection parts have been tested under load (500kg load-bearing capacity), and there is no weld cracking or structural damage, which meets the actual use requirements.

[0024] Example 2 like Figures 2-3 As shown, the difference from Embodiment 1 is that the boom assembly 20 further includes a channel steel telescopic boom 202, which includes a first channel steel 2021, a second channel steel 2022, a sliding block 2023, an adjusting bolt 2024, a second channel steel vertical boom 203, and a connecting plate 2031.

[0025] In this embodiment, specifically: the back sides of the first channel steel 2021 and the second channel steel 2022 are attached to each other, and the back sides of the first channel steel 2021 and the second channel steel 2022 are provided with through slots for the adjusting bolt 2024 to pass through, and the other end of the adjusting bolt 2024 is threadedly connected to a sliding block 2023.

[0026] The design of the first channel steel 2021 and the second channel steel 2022 with their backs touching each other allows them to slide relative to each other along the length direction, thereby changing the total length of the channel steel telescopic boom 202. The "through grooves" on the back of both provide a moving channel for the adjusting bolt 2024. Combined with the threaded connection of the sliding block 2023, when the length is adjusted to the "required length H" that matches the pipe elevation, tightening the adjusting bolt locks their relative positions, preventing length deviation. This structure eliminates the need for secondary cutting or welding of the boom on-site, solving the problems of "poor elevation adaptability and low construction error tolerance" inherent in traditional booms.

[0027] The channel steel telescopic boom 202 can compensate for the difference in installation height between the two booms by finely adjusting the length (sliding the first / second channel steel and locking it), ensuring that the two ends of the horizontal channel steel crossarm are at the same height when connected to the boom. This directly helps to achieve the design goal of "crossarm levelness compliance" and avoids the safety hazard of uneven pipeline stress caused by boom length deviation.

[0028] Example 3 like Figures 4-8 As shown, the difference from Embodiment 1 is that: a multi-pipe channel steel welded load-bearing support and hanger that ensures the horizontality of the crossarm, the fixing component 10 further includes a horizontal fixing plate 102 and a reinforcing rib 1021, the boom assembly 20 includes a second channel steel vertical boom 203 and a connecting plate 2031, the bottom of the horizontal fixing plate 102 is connected to the top two sides of the second channel steel vertical boom 203 through the reinforcing rib 1021, and the bottom of the opposite sides of the two sets of second channel steel vertical booms 203 are welded to the horizontal channel steel crossarm 30 through the connecting plate 2031.

[0029] In this embodiment, specifically: a pipe buffer bracket 50 is installed on the upper rib plate of the horizontal channel steel crossbeam 30. The pipe buffer bracket 50 includes a mounting plate 501, an arc-shaped support plate 502, and a buffer assembly 503. The buffer assembly 503 is placed between the mounting plate 501 and the arc-shaped support plate 502.

[0030] In this embodiment, specifically: the buffer assembly 503 includes a base 5031, a sleeve 5032, a spring 5033, a flange 5034, a piston 5035, and a limiting block 5036; A sleeve 5032 is fixedly connected to the top surface of the base 5031. A spring 5033 is provided inside the sleeve 5032. The top of the sleeve 5032 is connected to the flange 5034 by bolts. The bottom of the piston 5035 passes through the inside of the flange 5034 and is connected to the spring 5033 by a limiting block 5036.

[0031] Working principle: The horizontal fixed plate 102 serves as a transitional connection between the structural beam and the vertical boom 203 of the second channel steel. Its bottom is welded to both sides of the top of the boom through the reinforcing ribs 1021 to form a "triangular support structure" (fixed plate-reinforcing rib-boom). This can effectively disperse the bending and shearing forces generated by the vertical load of the boom, avoid deformation at the top of the boom due to concentrated force, and solve the problem that traditional booms are prone to tilting when only one side is welded. The reinforcing ribs 1021 are symmetrically connected to both sides of the boom. During installation, the welding of the reinforcing ribs can be used to position the boom, ensuring that the second channel steel vertical boom 203 is perpendicular to the horizontal fixing plate 102. This provides a "vertical reference guarantee" for the horizontality of the crossarm, which is in line with the core objective of the referenced document to "better guarantee the horizontality of the crossarm". Two sets of second channel steel vertical booms 203 are welded to horizontal channel steel crossarms 30 via connecting plates 2031. The connecting plates 2031 can be pre-processed to a uniform size and directly fit the bottom of the boom and the side of the crossarm during installation. This avoids the problem of misalignment between the boom and the crossarm in the traditional "direct welding" method, ensuring that the connection height at both ends of the crossarm is consistent and directly assisting in achieving "crossarm levelness standard". The connecting plate 2031 is welded to both the boom and the crossarm. Compared to the direct connection between the boom and the crossarm, this increases the weld length and contact area, conforming to the design principle of "longer welds result in higher strength" in the referenced document. It can withstand the weight of multiple pipes laid in parallel and is suitable for "multi-pipe support" requirements. The arc-shaped support plate 502 fits against the outer wall of the pipe. Compared to the "point contact" of traditional pipe clamps, the arc-shaped structure can disperse the pipe pressure and prevent the pipe from deforming due to excessive local stress. At the same time, multiple buffer brackets can be evenly arranged along the upper ribs of the horizontal channel steel crossarm 30 to support the parallel laying of multiple pipes. The buffer component 503 is placed between the mounting plate 501 and the arc-shaped support plate 502. It can absorb the vibration of the pipe during operation (such as the water flow impact vibration of data center chilled water pipes), preventing the vibration from being transmitted to the support body and causing the weld to loosen or the crossarm to shift, ensuring the "long-term stability" of the support and reducing the workload of later maintenance. The sleeve 5032 encloses the spring 5033 to prevent dust and moisture from corroding the spring and causing rust failure, thus extending the life of the buffer assembly. The flange 5034 is connected to the sleeve by bolts, facilitating disassembly and replacement if the spring is damaged later. The piston 5035 connects the arc-shaped support plate to the spring, and the limit block 5036 prevents the spring from being over-compressed or stretched, thus preventing permanent deformation and ensuring that the buffer assembly is always within its effective working range. This avoids pipeline displacement caused by buffer failure and further guarantees the "long-term stability" of the support.
