Description

Technical Field

[0001] The utility model relates to the technical field of seismic equipment, in particular to a novel connector. Background Technique

[0002] In construction projects, the pipeline system plays a crucial role. To reduce the damage to the pipeline system caused by earthquakes, the installation of seismic brackets becomes particularly critical. These brackets can effectively control the vibration of the pipeline during earthquakes and safely transfer the load to the structure of the building. When an earthquake occurs, the seismic brackets provide the necessary stability for the pipeline and resist the vibration impacts from all directions. All components of the seismic brackets should be prefabricated products, and the design should facilitate installation and operation. Currently, traditional seismic brackets mainly use U-shaped pipe clamp connectors to fix the pipeline, and cooperate with various seismic installation components to provide sufficient longitudinal and lateral supports to resist vibrations in different directions.

[0003] However, the existing U-shaped pipe clamp connectors have some design deficiencies. First, the assembly process of the U-shaped pipe clamp connector is relatively complex, and it is necessary to accurately align the through holes of the upper pipe clamp part and the lower pipe clamp part, which not only increases the operation difficulty but also affects the work efficiency. Second, the radial shear force at the hinge hole position of the U-shaped pipe clamp connector is completely borne by the through bolts. The through bolts are worn for a long time at this part, which is extremely easy to cause corrosion problems. This not only affects the strength of the bolts but also may cause bolt fracture, thus affecting the stability and safety of the entire pipeline system. Content of the Utility Model

[0004] The purpose of the utility model is to provide a novel connector to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A novel connector, characterized in that: it includes a U-shaped pipe clamp connector; the U-shaped pipe clamp connector includes an upper pipe clamp part arranged in a U shape, a lower pipe clamp part arranged in a U shape, and a through bolt, and the through bolt horizontally penetrates through both the upper pipe clamp part and the lower pipe clamp part to realize the hinge connection between the upper pipe clamp part and the lower pipe clamp part.

[0007] A pipeline clamping space is formed inside the U-shaped bend of the lower pipe clamp part, including a first U-shaped bend main body and first through holes respectively arranged at both ends of the first U-shaped bend main body; an insulating anti-slip sleeve is arranged on the contact surface between the lower pipe clamp part and the U-shaped bend of the pipeline.

[0008] The upper pipe clamp part is reversely hinged to the outside of the lower pipe clamp part, and includes a second U-shaped bending main body, cylindrical first limiting bumps fixedly arranged on one side of both ends of the second U-shaped bending main body close to the lower pipe clamp part, and a second through hole penetrating through both the first limiting bump and the second U-shaped bending main body along the axial line direction of the first limiting bump; the second through hole matches the through bolt.

[0009] The first through hole matches the outer diameter of the first limiting bump; during installation, first insert the first limiting bump into the first through hole to form a limiting pre-installation, and then align the through bolt with the second through hole to penetrate through both the upper pipe clamp part and the lower pipe clamp part to form a hinged connection.

[0010] Preferably, the insulating anti-slip sleeve is an EPDM insulating rubber inner lining, and its cross-section is C-shaped. It is detachably wrapped on the side of the first U-shaped bending main body close to the pipeline, with insulation, shock absorption, noise reduction, and oxidation resistance, and is convenient for disassembly, installation, and maintenance.

[0011] Preferably, the side of the insulating anti-slip sleeve in contact with the pipeline is provided with wavy anti-slip grooves to improve anti-slip performance.

[0012] Preferably, the side of the insulating anti-slip sleeve in contact with the first U-shaped bending main body is evenly distributed with no less than 3 limiting installation posts. Correspondingly, the first U-shaped bending main body is provided with limiting installation through holes matching the limiting installation posts; the limiting installation posts and the limiting installation through holes are in limiting abutment, which is convenient for installation and prevents displacement.

[0013] Preferably, a limiting sleeve is sleeved on the through bolt; the length of the limiting sleeve matches the U-shaped opening specification of the first U-shaped bending main body to prevent the upper pipe clamp part and the lower pipe clamp part from deforming due to excessive clamping of the through bolt.

[0014] Preferably, the height of the first limiting bump is equal to the thickness of the second U-shaped bending main body, which ensures the structural strength and improves the ability to resist radial shear force.

[0015] Compared with the prior art, a new type of connector of the present application has the following beneficial effects:

[0016] In the present utility model, a cylindrical first limiting bump is arranged on the hinged surface of the upper pipe clamp part. During installation, first completely place the first limiting bump into the first through hole of the lower pipe clamp part to quickly form a limiting pre-installation of the upper pipe clamp part and the lower pipe clamp part, which eliminates the step of precisely aligning the through holes of the upper pipe clamp part and the lower pipe clamp part for the subsequent installation of the through bolt, reduces the operation difficulty, and improves the work efficiency. In addition, the setting of the first limiting bump can assist the through bolt to bear the radial shear force at the hinged surface position, improve the service life of the through bolt, and ensure the structural stability and safety of this connector.

Specific embodiments

[0025] The following is a further detailed description through specific embodiments:

[0026] Embodiment 1

[0027] As Figures 1-3 shown, this embodiment shows a new type of connector, including a U-shaped pipe clamp connector 6; the U-shaped pipe clamp connector 6 includes an upper pipe clamp part 61 arranged in a U shape, a lower pipe clamp part 62 arranged in a U shape, and a through bolt 64. The through bolt 64 horizontally penetrates through both the upper pipe clamp part 61 and the lower pipe clamp part 62 to achieve the hinged connection between the upper pipe clamp part 61 and the lower pipe clamp part 62. In the case of an earthquake or other vibrations, the hinged connection between the upper pipe clamp part 61 and the lower pipe clamp part 62 can absorb and disperse the vibration energy through its rotatable characteristics, reducing the impact on the pipeline 5. Specifically, in the overall connection of the seismic support, the top of the upper pipe clamp part 61 can be bolted to the floor concrete structure 2 in the vertical direction through the full-thread screw 1, and one end of the through bolt 64 can be bolted to the floor concrete structure 2 in the lateral direction through the hinge 3 and the channel steel 4, having good lateral and longitudinal seismic performance; among them:

[0028] A pipe clamping space is formed inside the U-shaped bend of the lower pipe clamp part 62 for supporting and fixing the pipe 5. The lower pipe clamp part 62 includes a first U-shaped bend main body 621 and first through holes 622 respectively arranged at both ends of the first U-shaped bend main body 621; an insulating anti-slip sleeve 63 is arranged on the U-shaped bend contact surface between the lower pipe clamp part 62 and the pipe 5, which can prevent the pipe 5 from sliding while buffering vibration and reducing noise.

[0029] The upper pipe clamp part 61 is reversely hinged to the outside of the lower pipe clamp part 62, and includes a second U-shaped bend main body 611, cylindrical first limiting convex blocks 612 fixedly arranged on one side of both ends of the second U-shaped bend main body 611 close to the lower pipe clamp part 62, and a second through hole 613 penetrating through both the first limiting convex block 612 and the second U-shaped bend main body 611 along the axial line direction of the first limiting convex block 612; the second through hole 613 matches the through bolt 64.

[0030] The outer diameter of the first through hole 622 matches that of the first limiting convex block 612; during installation, first insert the first limiting convex block 612 into the first through hole 622 to form a limit pre-installation, and then align the through bolt 64 with the second through hole 613, and penetrate through both the upper pipe clamp part 61 and the lower pipe clamp part 62 to form a hinged connection. Specifically, during pre-installation, the first limiting convex block 612 can be quickly placed into the first through hole 622 to quickly form a limit connection between the upper pipe clamp part 61 and the lower pipe clamp part 62, eliminating the step of precisely aligning the through holes of the upper pipe clamp part 61 and the lower pipe clamp part 62 when installing the through bolt 64 in the traditional structure, reducing the operation difficulty and improving the work efficiency. At the same time, the first limiting convex block 612 is completely filled in the first through hole 622. In the traditional structure, one side of the hinged surface between the upper pipe clamp part 61 and the lower pipe clamp part 62 is subjected to the vertical downward pulling force of the pipe 5 in the lower pipe clamp part 62, and the other side is subjected to the vertical upward pulling force of the upper pipe clamp part 61. In this embodiment, the first limiting convex block 612 can assist the through bolt 64 to bear the radial shear force at the hinged surface position, improving the service life of the through bolt 64 and ensuring the structural stability and safety of this connector.

[0031] Embodiment 2

[0032] As Figures 1-3 and Figures 6-7As shown, another embodiment shows a new type of connecting piece based on Embodiment 1. In this embodiment, the insulating anti-slip sleeve 63 is an EPDM insulating rubber lining. EPDM insulating rubber, also known as ethylene propylene diene monomer rubber, is a synthetic rubber made from a terpolymer of ethylene, propylene, and non-conjugated diene. EPDM insulating rubber has good insulation, corrosion resistance, environmental friendliness, and antioxidant properties. In this embodiment, the cross-section of the EPDM insulating rubber lining is C-shaped and can be detachably wrapped around the side of the first U-shaped bend main body 621 close to the pipeline 5, facilitating disassembly and assembly.

[0033] Furthermore, in a further feasible implementation manner of this embodiment, as Figure 6 shown, on the side where the insulating anti-slip sleeve 63 contacts the pipeline 5, there are wavy anti-slip grooves 631, which improve the anti-slip property between the insulating anti-slip sleeve 63 and the pipeline 5. In some other further feasible implementation manners of this embodiment, as Figure 7 shown, on the side where the insulating anti-slip sleeve 63 contacts the first U-shaped bend main body 621, there are evenly distributed no less than 3 limit installation posts 632. Correspondingly, the first U-shaped bend main body 621 is provided with limit installation through holes matching the limit installation posts 632. When installing, the insulating anti-slip sleeve 63 with a C-shaped cross-section is sleeved on the first U-shaped bend main body 621. At this time, the limit installation posts 632 and the limit installation through holes are in limit abutment, having the functions of positioning and preventing displacement.

[0034] Embodiment 3

[0035] As Figures 1-5 shown, another embodiment shows a new type of connecting piece based on Embodiment 1. In a further feasible implementation manner of this embodiment, a limit sleeve 65 is sleeved on the through bolt 64; the length of the limit sleeve 65 matches the U-shaped opening specification of the first U-shaped bend main body 621, preventing the upper pipe clamp part 61 and the lower pipe clamp part 62 from being deformed due to excessive clamping of the through bolt 64, which affects the structural stability and safety.

[0036] Embodiment 4

[0037] As Figures 1-3 shown, another embodiment shows a new type of connecting piece based on Embodiment 1. In a further feasible implementation manner of this embodiment, the height of the first limit convex block 612 is equal to the thickness of the second U-shaped bend main body 611. On the one hand, it ensures the limit connection effect of pre-installation, and on the other hand, it ensures the structural strength and improves the ability to resist radial shear force.

It should be noted that for those skilled in the art, without departing from the structure of the present utility model, several modifications and improvements can be made, which should also be regarded as the protection scope of the present utility model, and these will not affect the implementation effect of the present utility model and the practicality of the patent.
