Description

Technical Field

[0001] This invention relates to the field of building engineering technology, and in particular to a method for insulating pipe supports. Background Technology

[0002] In modern industrial production environments, pipelines are a core component of building safety, and their stable operation is crucial. Depending on the industrial environment, additional protective measures are required during pipeline construction to ensure operational safety. For example, in industries such as petrochemicals, power generation, and metallurgy, pipeline systems often traverse complex electrical work areas or strong electromagnetic environments. If pipelines and their metal support structures are not effectively insulated from buildings (ground), stray current loops may form, leading to accelerated electrochemical corrosion, or electromagnetic interference may affect the stability of measurement and control signals, seriously threatening production safety and equipment lifespan.

[0003] In existing technologies, common insulation measures only use a single insulating gasket or sleeve, lacking a systematic insulation design from "pipe-support" to "support-building," resulting in incomplete insulation, insufficient reliability, or affecting the structural strength of the support. Therefore, there is an urgent need for a pipe support treatment method that can provide double, reliable insulation without affecting the stability of the supporting structure. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides a method for insulating pipe supports, which ensures the quality and safety of pipe installation, reduces the impact of current and electromagnetic fields on pipe equipment, extends service life, and better guarantees the functionality of the pipes.

[0005] To achieve this technical objective, the present invention adopts the following solution:

[0006] This invention provides a method for insulating pipe supports, comprising the following steps: S1. Weld the support steel plate and the support channel steel into an integral component, and install welding bolts on the embedded steel plate of the building. S2. Install the insulating sleeve, insulating pad, and support steel plate pre-assembled with the support channel steel onto the welding bolts in sequence. S3. Install the insulating washer, the second washer, and the second nut on the welding bolt in sequence and tighten them. S4. Install an insulating cap on the end of the welding bolt, and cover the second nut and the second washer with the insulating cap; S5. Place the pipe on the support channel steel and install an electrically insulating rubber tube at the contact point between the pipe and the support channel steel. S6. Use U-bolts, the first washer, and the first nut to clamp and fix the pipe and the electrically insulating rubber tube together on the support channel steel.

[0007] Furthermore, in step S2, the planar dimensions of the insulating pad are larger than the planar dimensions of the embedded steel plate.

[0008] Furthermore, in step S2, the diameter of the openings on the insulating pad and the support steel plate for the welding bolts to pass through is larger than the outer diameter of the insulating sleeve.

[0009] Furthermore, in step S5, the central axis of the electrically insulating rubber tube coincides with the central support surface of the support channel steel.

[0010] Furthermore, the insulating pads, insulating washers, and insulating caps are made of SMC-1 material.

[0011] Furthermore, the insulating sleeve is made of epoxy-laminated glass cloth tubing and is installed between the welding bolts and the insulating pad and the support steel plate.

[0012] Furthermore, the electrically insulating rubber tube is made of elastic rubber material.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] Double insulation for high safety: This invention sets up two independent insulation barriers, "support-building" and "pipe-support", forming a "double insurance" for electrical isolation, cutting off the path of stray current and induced current, and greatly improving insulation reliability.

[0015] Balancing structural strength and insulation performance: This invention uses SMC-1 material as the insulating component, so that the insulating layer also serves as the structural force transmission layer, avoiding the problem of weakening the strength of the connection node due to the introduction of insulating components.

[0016] Construction-friendly and quality-controllable: The flexible design of the insulating sleeve facilitates on-site installation and hole alignment; the dimensional design principles of each component are clearly defined, ensuring assembly accuracy and insulation effectiveness, which is conducive to standardized construction and quality control.

[0017] Good maintainability: Each insulating component is modular, and if local damage occurs, it can be replaced accordingly without dismantling the entire support or piping system, thus reducing maintenance costs. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments.

[0025] Please see Figures 1 to 5 This invention provides a method for insulating pipe supports, comprising the following steps: S1. According to the design, the support steel plate 8 and the support channel steel 1 are welded into an integral component, and the welding bolts 9 are precisely positioned and fully welded on the building embedded steel plate 6. S2. Install insulating sleeves 10 sequentially on welding bolts 9, then install insulating pads 7, and then install the overall assembly of bracket channel steel 1 and bracket steel plate 8; wherein the plane dimension of insulating pad 7 is larger than the plane dimension of embedded steel plate 6 to ensure that insulating pad 7 can completely cover embedded steel plate 6. The insulating pad 7 and the support steel plate 8 are provided with openings for the welding bolts 9 to pass through. The diameter of the openings is slightly larger than the outer diameter of the insulating sleeve 10 to ensure that the insulating sleeve 10 can be completely wrapped and does not bear shear force. S3. Install the insulating washer 11, the second washer 12 and the second nut 13 on the welding bolt 9 in sequence and tighten them; S4. Install an insulating cap 14 at the end of the welding bolt 9. The internal shape and size of the insulating cap 14 match the external dimensions of the second nut 13 and the second washer 12, so that the insulating cap 14 can completely cover the second nut 13 and the second washer 12, thereby achieving insulation and sealing of the connection point. S5. Place the pipe to be installed on the support channel steel 1, and install the electrically insulating rubber tube 3 at the contact point between the pipe and the support channel steel 1. Adjust the tube so that the central axis of the electrically insulating rubber tube 3 coincides with the central support surface of the support channel steel 1. S6. Using U-bolts 2, pass over the pipe and the electrically insulating rubber tube 3, with both ends passing through the holes on the flange of the support channel steel 1. Then, install the first washer 5 and the first nut 4 in sequence, and tighten the first nut 4 symmetrically and evenly to clamp and fix the pipe and the electrically insulating rubber tube 3 together on the support channel steel 1, thus completing the pipe installation and insulation fixation.

[0026] In one specific embodiment, the insulating pad 7, the insulating washer 11, and the insulating cap 14 are made of SMC-1 material (sheet film plastic). SMC-1 material has excellent electrical insulation properties, high mechanical strength, and dimensional stability, which can meet the dual requirements of insulation and structural strength of the support node.

[0027] In one specific embodiment, the insulating sleeve 10 is made of epoxy-laminated glass cloth tubing and is installed between the welding bolt 9 and the insulating pad 7 and the support steel plate 8. This material has a high insulation level, as well as high mechanical strength and structural stability, which can well support the internal structure and fix the external steel structure support, ensuring the stability of the structure.

[0028] In one specific embodiment, the electrically insulating rubber tube 3 is made of elastic rubber material, which not only provides reliable insulation, but its own elasticity can also effectively absorb and buffer the vibration and micro-displacement of the pipeline caused by thermal expansion and contraction and external environment, thus playing a role in vibration reduction and protection.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; if these modifications and variations fall within the scope of the claims of the present invention and their equivalents, they should all be considered to be within the protection scope of the present invention.
