Description

Technical Field

[0001] This utility model relates to the field of pipe clamp technology, and in particular to a weld-free water pipe clamp with longitudinal and lateral seismic resistance. Background Technology

[0002] In the field of building pipeline installation, the stability of seismic supports for water pipes is directly related to building safety, and pipe clamps, as the core components of seismic supports, are of paramount importance. Currently, most seismic support pipe clamps on the market rely on welding processes for forming, which has significant limitations. On the one hand, welding quality is greatly affected by the skill level of the operators, easily leading to problems such as weak welds and stress concentration, resulting in unstable mechanical properties of the pipe clamps and posing a safety risk of detachment and breakage under external forces such as earthquakes. On the other hand, the welding process is complex, has a long processing cycle, and requires specialized welding equipment and technicians, significantly increasing the overall cost of production and processing. Furthermore, the pollutants generated during welding are inconsistent with the development trend of green production. In addition, traditional welded pipe clamps require on-site fitting and welding during installation, resulting in poor flexibility and difficulty in disassembly during later maintenance, which is not conducive to pipeline inspection and replacement.

[0003] Therefore, it is necessary to provide a new weld-free water pipe clamp with longitudinal and lateral seismic resistance to solve the above-mentioned technical problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a weld-free water pipe clamp with longitudinal and lateral seismic resistance.

[0005] The weldless water pipe clamp with longitudinal and lateral seismic resistance provided by this utility model includes a semi-circular clamp piece. The semi-circular clamp pieces are arranged in pairs, and the upper and lower end faces of the semi-circular clamp pieces are fixedly fitted with mating lugs. Each semi-circular clamp piece is fitted with a semi-circular rubber pad.

[0006] A U-shaped cover is inserted between the two semi-circular clips, and curved bends are distributed on both sides of the U-shaped cover;

[0007] The U-shaped cover and two semi-circular clamps are equipped with a first screw, and a first nut with a threaded connection is installed on the first screw.

[0008] Preferably, the two sides of the semicircular rubber pad are bent towards the back to form an open U-shaped structure. The semicircular rubber pad is attached to the inner arc wall of the semicircular clip, and the bent part of the semicircular rubber pad is attached to the outer arc wall of the semicircular clip.

[0009] Preferably, both sides of the U-shaped cover have mating holes.

[0010] Preferably, the mating lugs above the two semicircular clips are inserted into the U-shaped cover and fit against the inner walls of both sides of the U-shaped cover.

[0011] Preferably, a second screw is inserted into the mating lugs below the two semicircular clips, and a second nut with a threaded connection is installed on the second screw.

[0012] Preferably, a first flat washer and a second flat washer are respectively fitted onto the first screw and the second screw.

[0013] Preferably, the upper surface of the U-shaped cover has mounting holes.

[0014] Compared with related technologies, the weld-free water pipe clamp with longitudinal and lateral seismic resistance provided by this utility model has the following beneficial effects:

[0015] This utility model adopts a combined assembly structure of semi-circular clamps, U-shaped covers, and screw nuts, completely eliminating welding processes and avoiding mechanical property fluctuations caused by welding. This makes the overall pipe clamp structure stable, with uniform stress, reducing safety risks. At the same time, the welding-free design simplifies the processing flow, eliminating the need for professional welding equipment and technicians, shortening the production cycle, and significantly reducing overall processing costs. Furthermore, the assembly process does not require on-site open flames, meeting green construction requirements. The curved bends evenly distributed on both sides of the U-shaped cover can effectively resist the torque force transmitted by the connecting lugs above the semi-circular clamps, giving the pipe clamp strong lateral and longitudinal seismic resistance, capable of coping with horizontal vibrations of the pipeline caused by external forces such as earthquakes. The semi-circular rubber pads fitted on the semi-circular clamps not only protect the pipeline surface from damage during clamping but also utilize the elastic buffering properties of rubber to further absorb vibration energy, while isolating noise generated during pipeline operation and reducing the transmission of noise to the building structure.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0022] Please see Figures 1 to 2 The present invention provides a weldless water pipe clamp with longitudinal and lateral seismic resistance, the weldless water pipe clamp with longitudinal and lateral seismic resistance includes a semi-circular clamp 1, a U-shaped cover 2 and a semi-circular rubber pad 3.

[0023] In the embodiments of this utility model, please refer to Figure 1 and Figure 2 The semicircular clips 1 are arranged in pairs, and the upper and lower end faces of the semicircular clips 1 are fixedly fitted with mating lugs 11. Each semicircular clip 1 is fitted with a semicircular rubber pad 3. Specifically, the two sides of the semicircular rubber pad 3 are bent towards the back and form an open U-shaped structure. The semicircular rubber pad 3 is attached to the inner arc wall of the semicircular clip 1, and the bent part of the semicircular rubber pad 3 is attached to the outer arc wall of the semicircular clip 1.

[0024] A U-shaped cover 2 is inserted between the two semi-circular clamping pieces 1, and curved bending parts 21 are evenly distributed on both sides of the U-shaped cover 2. The two side walls of the U-shaped cover 2 are provided with mating holes 2a. The mating lugs 11 above the two semi-circular clamping pieces 1 are inserted into the U-shaped cover 2 and fit against the inner walls of both sides of the U-shaped cover 2. The U-shaped cover 2 and the two semi-circular clamping pieces 1 are equipped with a first screw 4, and a first nut 41 with threaded connection is installed on the first screw 4. The mating lugs 11 below the two semi-circular clamping pieces 1 are inserted with a second screw 5, and a second nut 51 with threaded connection is installed on the second screw 5.

[0025] It should be noted that when clamping the pipe, the upper semi-circular rubber pads 3 are first fitted onto both semi-circular clamping pieces 1. Then, the two semi-circular clamping pieces 1 are attached to both sides of the pipe, and the upper and lower mating lugs 11 are kept in correspondence. Then, the U-shaped cover 2 is inserted into the mating lugs 11 above the two semi-circular clamping pieces 1. It is fixed by the bolt structure formed by the first screw 4 and the first nut 41. Then, the bolt structure formed by the second screw 5 and the second nut 51 is passed through the mating lugs 11 below the two semi-circular clamping pieces 1 for fixing. The clamping of the pipe can be completed.

[0026] Since both semicircular clamps 1 are fitted with semicircular rubber pads 3, on the one hand, the semicircular clamps 1 can improve the protection of the pipe clamping part, and on the other hand, the semicircular rubber pads 3 can be used to isolate pipe noise, thereby reducing the noise transmitted to the building structure through the semicircular clamps 1.

[0027] In addition, since curved bends 21 are evenly distributed on both sides of the U-shaped cover 2, the curved bends 21 can be used to resist the torque force transmitted from the mating lugs 11 above the semi-circular clamp 1, so that the whole set of pipe clamps can resist the force of lateral and longitudinal horizontal vibration of the pipe.

[0028] In this embodiment: the upper surface of the U-shaped cover 2 is provided with mounting holes 2b. Multiple sets of seismic bracing 6 are installed in the mounting holes 2b by bolts. The seismic bracing 6 is fixed to the concrete floor slab, thereby completing the hoisting of the water pipe by the weld-free water pipe clamp.

[0029] Furthermore, a first flat washer 42 and a second flat washer 52 are respectively fitted on the first screw 4 and the second screw 5. The installation of the first flat washer 42 and the second flat washer 52 increases the force-bearing area and disperses the concentrated pressure to a larger area, thereby effectively protecting the mating lug 11 from damage.

[0030] Therefore, this application adopts a combined assembly structure of semi-circular clamp 1, U-shaped cover 2 and screw nut, completely eliminating the welding process and avoiding the mechanical performance fluctuation problem caused by welding. This makes the overall structure of the pipe clamp stable, the force is uniform, and the safety risk is reduced. At the same time, the welding-free design simplifies the processing flow, eliminates the need for professional welding equipment and technicians, shortens the production cycle, and significantly reduces the overall processing cost. Moreover, the assembly process does not require on-site hot work, which meets the requirements of green construction. The curved bending parts 21 distributed on both sides of the U-shaped cover 2 can effectively resist the torque force transmitted by the connecting lug 11 above the semi-circular clamp 1, so that the pipe clamp has strong lateral and longitudinal seismic resistance and can cope with the horizontal vibration of the pipeline caused by external forces such as earthquakes. The semi-circular rubber pad 3 sleeved on the semi-circular clamp 1 can not only protect the surface of the pipeline and avoid damage during clamping, but also use the elastic buffering characteristics of rubber to further absorb vibration energy. At the same time, it isolates the noise generated by the pipeline during operation and reduces the transmission of noise to the building structure.

[0031] Furthermore, this weld-free water pipe clamp achieves rapid assembly via the first screw 4, the first nut 41, the second screw 5, and the second nut 51, requiring no complex tools and resulting in high installation efficiency. The mounting holes 2b on the U-shaped cover 2 facilitate connection and fixation with the seismic support 6, allowing for flexible adaptation to different hoisting requirements. During later maintenance, the components can be separated simply by disassembling the screws and nuts, facilitating pipe inspection and replacement and significantly reducing maintenance costs.

[0032] Among them, the semi-circular rubber pad 3 is made of modified rubber material that is resistant to aging and high temperature, such as EPDM rubber, thereby improving its service life and environmental adaptability. At the same time, an anti-aging coating can be applied to the surface of the semi-circular rubber pad 3 to further enhance its protective performance and slow down the aging rate.

[0033] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
