Description

Technical Field

[0001] This utility model belongs to the field of building electromechanical water supply and drainage, specifically an eccentric anti-seismic pipe clamp that can be made of 3D printed polyurethane material. Background Technology

[0002] After prefabrication of standardized supports on-site, the supports often have uniform elevations. However, when the pipe diameter changes, the bottom elevation of the pipe changes, and the supports cannot provide adequate load-bearing capacity, affecting the straightness and aesthetics of the pipe and failing to meet relevant acceptance specifications. Secondly, traditional seismic and anti-sway supports for pipeline systems generally rely on diagonal bracing, which is made of high-strength C-channel steel. There is no special reinforcement for pipe clamps, so after lateral seismic forces occur, the load is concentrated on the pipe clamps, causing them to deform irreversibly. Thirdly, existing universal pipe clamps cannot be well matched with current seismic products on the market; different manufacturers have different standard bore diameters. Finally, the injection molding production cost of honeycomb structures is high.

[0003] Traditional prefabricated supports often result in uniform support elevations. However, when the pipe diameter changes, the bottom elevation of the pipe changes, causing the supports to fail to provide adequate load-bearing capacity, affecting the straightness and aesthetics of the pipe, and failing to meet relevant acceptance specifications. Furthermore, the seismic and anti-sway supports of the aforementioned pipeline systems are generally mainly diagonal braces made of high-strength C-shaped channel steel, without any special reinforcement for the pipe clamps. When lateral seismic forces occur, the load is concentrated on the pipe clamps, causing irreversible deformation. Summary of the Invention

[0004] To solve the above problems, this utility model provides an eccentric shock-resistant pipe clamp that can be made of 3D printed polyurethane material.

[0005] This utility model adopts the following technical solution: an eccentric anti-vibration pipe clamp that can be made of 3D printed polyurethane material, comprising: An eccentric pipe support, wherein a central circular hole is provided in the middle of the eccentric pipe support for supporting the pipe; U-shaped metal clips are used to cover and fix the eccentric tube support, and connecting ears with through holes are provided on the outer side; The seismic interface module is fixed to the outer wall of the U-shaped metal clamp and is provided with a connection hole; Fastening bolts, through holes, and connecting holes are used to connect and fix U-shaped metal clamps and anti-vibration interface modules; The eccentric tube support has a porous energy-absorbing structure inside, which undergoes elastic deformation when the tube clamp is subjected to lateral force.

[0006] In some embodiments, the eccentric tube support is integrally molded from polyurethane and manufactured by 3D printing.

[0007] In some embodiments, the porous energy-absorbing structure of the eccentric tube support has a honeycomb topology.

[0008] In some embodiments, the eccentric tube support is provided with a plurality of limiting posts arranged laterally, and the limiting posts can be fixed by U-shaped metal clamps.

[0009] In some embodiments, the seismic interface module has multiple sockets, and each socket is provided with a U-shaped metal clamp connecting ear. The through hole of the connecting ear corresponds to the connecting hole of the seismic interface module, and a fastening bolt is provided therein. The fastening bolt is secured with an anti-loosening nut.

[0010] In some embodiments, the seismic interface module is provided with a threaded connecting rod, and the connecting rod is threaded with an anti-loosening nut for connecting to the hinge.

[0011] In some embodiments, the shape of the central circular hole is the same as the outer diameter of the two pipes to be connected, which is achieved by modifying the parameters of the 3D printing model.

[0012] In some embodiments, the cell wall thickness of the honeycomb topology is 0.5-3 mm, and the cell pore size is 3-8 mm.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. Precise Elevation Fit: The adjustable eccentricity design of the flexible pipe support directly compensates for the height difference caused by pipe diameter changes, eliminating the need for support modification.

[0014] 2. Self-recovering seismic resistance: The porous energy-absorbing structure inside the pipe support dissipates energy through elastic deformation when encountering lateral seismic forces, and automatically resets after unloading.

[0015] 3. Immediate compatibility: Standardized seismic interfaces directly match existing bracing systems without the need for additional conversion parts.

[0016] 4. Triple safety protection: a synergistic protection mechanism consisting of limit protrusions to prevent loosening, elastomers to resist fracture, and honeycomb structure to resist fatigue.

[0017] 5. Overall cost optimization: Reduce prefabrication time for supports, reduce the quantity of storage specifications, and eliminate the cost of replacing pipe clamps after a disaster. Attached Figure Description

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] like Figure 1 As shown, an eccentric anti-vibration pipe clamp made of 3D-printed polyurethane material includes: an eccentric pipe support 1, with a central circular hole in the middle for supporting the pipe; a U-shaped metal clamp 2 for covering and fixing the eccentric pipe support 1, with a connecting lug having a through hole on its outer side; an anti-vibration interface module 5 fixed to the outer wall of the U-shaped metal clamp 2, with a connecting hole; and a fastening bolt 4 penetrating the through hole and the connecting hole for connecting and fixing the U-shaped metal clamp 2 and the anti-vibration interface module 5; the eccentric pipe support 1 has a porous energy-absorbing structure inside, which undergoes elastic deformation when the pipe clamp is subjected to lateral force.

[0021] Specifically, the eccentric tube support 1 is integrally molded from polyurethane and manufactured by 3D printing. The porous energy-absorbing structure of the eccentric tube support 1 has a honeycomb topology. The cell wall thickness of the honeycomb topology is 0.5-3mm, and the cell diameter is 3-8mm. Multiple limiting posts 6 are arranged laterally on the eccentric tube support 1, and the limiting posts 6 can be fixed by U-shaped metal clamps 2.

[0022] The U-shaped metal clamp 2 has elongated holes at its two feet, and bolts are installed in the elongated holes. After the U-shaped metal clamp 2 fixes the pipe in a certain position, it is secured by the bolts in the elongated holes.

[0023] The seismic interface module 5 has multiple sockets, each containing a U-shaped metal clip 2 with a connecting lug. The through hole of the connecting lug corresponds to the connecting hole of the seismic interface module 5, and a fastening bolt 4 is installed therein. The fastening bolt 4 is secured with a lock nut 3. The seismic interface module 5 is provided with a threaded connecting rod, on which a lock nut 3 is threadedly connected for connecting to a hinge.

[0024] The shape of the central circular hole in the middle of the eccentric pipe support 1 is the same as the outer diameter of the two pipes to be connected. This is achieved by modifying the parameters of the 3D printing model and is manufactured on-site according to different pipe designs.

[0025] In a specific embodiment, Cut and weld the profiles according to the elevation shown in the drawings. There is no need to consider pipe diameter changes. Arrange and install them according to the spacing requirements of the specifications.

[0026] Based on the straightness requirements of the upstream pipe core and specifications, calculate the pipe eccentricity and then fabricate the corresponding eccentric pipe support 1.

[0027] Drill holes according to the two hole dimensions W of the pipe clamp width. After completing the anti-corrosion treatment, install the pipe clamp and adjust the limit post 6 to the center position, ensuring it is vertical and not tilted.

[0028] Tighten the fastening bolts 4 and their anti-loosening nuts 3 to ensure that the flexible tube support undergoes slight compression deformation and the limiting post 6 does not shift.

[0029] Connect the connecting rod on the seismic interface module to the connecting hinge provided by the seismic product, and tighten the matching anti-loosening nut to secure it. Then install the diagonal brace and accessories provided by the seismic product normally.

[0030] Based on their construction experience, the project team's technical personnel, through discussion and experimentation, developed an eccentric seismic-resistant pipe clamp made of 3D-printed polyurethane material. This clamp allows for adjustment of the distance between the inner circle of the pipe support and the bracket, compensating for elevation differences caused by pipe diameter changes. Through a biomimetic seismic-resistant structure—specifically, the superimposed honeycomb-like self-deformation—it achieves wave damping and vibration reduction, lowering post-disaster recovery costs. Under the same construction environment, the use of this 3D-printed polyurethane eccentric seismic-resistant pipe clamp saves on the workload of prefabricated brackets, significantly improves safety, facilitates in-depth adjustments during construction, provides better seismic resistance, and results in a higher quality and more aesthetically pleasing finished pipeline system. This pipe clamp has already been used in the electromechanical section 2 of Beijing Metro Line 3 with significant results and has considerable potential for wider application. The analysis table is as follows: Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model 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 therein.
