Description

Technical Field

[0001] This utility model relates to the technical field of horseshoe-shaped connectors, and specifically discloses a horseshoe-shaped connector for earthquake-resistant supports and hangers. Background Technology

[0002] In the seismic protection system of building engineering, seismic bracing and hangers, through the connection of pipelines, transfer seismic loads to the main structure of the building and are key facilities for preventing earthquake damage. Horseshoe-shaped connectors, as the core component of seismic bracing and hangers, have the core function of connecting pipelines to the supports and hangers. On the one hand, the lower U-shaped body, which fits against the pipeline, provides support and restraint; on the other hand, the upper U-shaped body connects to the supports and hangers, forming a complete force transmission chain of "pipeline → connector → supports and hangers → main structure".

[0003] The horseshoe-shaped connectors in the prior art usually adopt a split structure, mainly composed of an upper U-shaped body and a lower U-shaped body. The two are connected by a threaded pin: the upper U-shaped body is sleeved on the outside of the lower U-shaped body, and its end insertion hole is aligned with the pin hole of the lower U-shaped body. The upper U-shaped body and the lower U-shaped body are connected by a threaded pin. The connection hole opened on the outer wall of the upper U-shaped body is used to connect the seismic bracing and hanger.

[0004] However, the above design has significant shortcomings: First, both the upper and lower U-shaped bodies are rigid metal structures, and the pin locking alone can only provide limited support for the pipeline, lacking effective clamping and fixing functions. During an earthquake, the pipeline is prone to slippage due to reciprocating loads, causing the supports and hangers to fail to fully exert their seismic resistance. Second, the split structure relies on a single-point connection with a pin, and the upper and lower U-shaped bodies are prone to relative rotation around the pin axis. Especially when connecting lateral seismic supports and hangers, the upper and lower U-shaped bodies are in a vertical state. Due to the self-weight load of the pipeline, the upper and lower U-shaped bodies are very prone to relative rotation, causing the upper and lower U-shaped bodies to deviate from the vertical state, which in turn causes the pipeline to move.

[0005] Therefore, a horseshoe-shaped connector for earthquake-resistant bracing and hangers is needed to solve the above problems. Utility Model Content

[0006] This utility model proposes a horseshoe-shaped connector for earthquake-resistant supports and hangers, which facilitates the provision of effective clamping force for pipelines and prevents pipelines from slipping due to reciprocating loads; at the same time, it can limit the relative rotation of the upper U-shaped body and the lower U-shaped body, significantly improving the stability of the connection structure.

[0007] This utility model is implemented as follows: a horseshoe-shaped connector for earthquake-resistant support and hanger includes a lower U-shaped body, an upper U-shaped body and a pipe. Rectangular grooves are opened through both the left and right ends of the lower U-shaped body. A pressure plate is arranged between the interiors of the two rectangular grooves. A clamping block is fixedly connected to the lower end of the pressure plate. An arc-shaped groove is opened at the lower end of the clamping block. A locking mechanism is arranged on the lower side of the pressure plate.

[0008] Both ends of the lower U-shaped body are provided with through holes, and the interior of each of the two holes is rotatably connected to a steering column that is fixedly connected to the upper U-shaped body. A limit mechanism is provided between the lower U-shaped body and the upper U-shaped body.

[0009] The limiting mechanism includes first limiting holes respectively opened at the left and right ends of the lower U-shaped body. The left and right sides of the outer wall of the upper U-shaped body are threaded with screws. The opposite ends of the two screws are fixedly connected with limiting steel columns that extend into the two first limiting holes and are adapted to the first limiting holes. The opposite ends of the two screws are each equipped with a hexagonal head. The front and rear sides of the two round holes are provided with second limiting holes.

[0010] As a preferred embodiment of the horseshoe-shaped connector for earthquake-resistant support and hanger of this utility model, the locking mechanism includes two internally threaded cylinders fixedly connected to the lower end of the pressure plate, and perforated plates are fixedly connected to both the left and right ends of the lower U-shaped body. Bolts that are threadedly connected to the inner walls of the two internally threaded cylinders are inserted into the interior of the two perforated plates.

[0011] As a preferred embodiment of the horseshoe-shaped connector for earthquake-resistant support and hanger of this utility model, sliding grooves are provided on both the front and rear sides of the inner walls of the two rectangular grooves, and two sliders are installed on both the front and rear sides of the pressure plate. The four sliders are slidably connected to the four sliding grooves respectively.

[0012] As a preferred embodiment of the horseshoe-shaped connector for earthquake-resistant support and hanger of this utility model, the inner walls of the two circular holes are provided with annular grooves, and the interiors of the two annular grooves are slidably connected with annular slide rails that are respectively fixedly connected to the two steering columns.

[0013] As a preferred embodiment of the horseshoe-shaped connector for earthquake-resistant support and hanger of this utility model, both the inner wall of the lower U-shaped body and the inner wall of the arc groove are fitted with rubber pads that fit against the outer wall of the pipe.

[0014] As a preferred embodiment of the horseshoe-shaped connector for earthquake-resistant support and hanger of this utility model, each of the two limiting steel columns has a tapered guide head on its opposite side.

[0015] As a preferred embodiment of the horseshoe-shaped connector for earthquake-resistant support and hanger of this utility model, a connecting hole is provided through the upper side of the outer wall of the upper U-shaped body.

[0016] The beneficial effects of this utility model are:

[0017] 1. The pipe passes through the interior of the lower U-shaped body, and the rubber liner on the inner wall of the lower U-shaped body initially adheres to the outer wall of the pipe to achieve initial positioning; the locking mechanism applies a continuous downward locking force to the pressure plate, driving the rubber liner in the arc groove of the clamping block to adhere tightly to the upper surface of the pipe, and the U-shaped structure of the lower U-shaped body forms a two-way envelope clamping, thereby achieving the purpose of providing effective clamping force to the pipe and preventing the pipe from slipping due to reciprocating loads.

[0018] 2. When adjusting the angle, the upper U-shaped body drives the screw and the limiting steel column to rotate synchronously through the steering columns at both ends. When the limiting steel column is aligned with the first limiting hole of the lower U-shaped body, the upper and lower U-shaped bodies are distributed vertically. By tightening the hexagonal head of the screw with a wrench, the limiting steel column is driven to be fully embedded in the first limiting hole or the corresponding second limiting hole. With the high-precision dimensional matching between the limiting steel column and the limiting hole, the relative rotation between the upper U-shaped body and the steering column can be effectively restricted, thereby significantly improving the stability of the connection structure.

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0027] Please see Figure 1-5 A horseshoe-shaped connector for earthquake-resistant support and hanger includes a lower U-shaped body 1, an upper U-shaped body 2 and a pipe 3. Rectangular grooves 4 are opened through both the left and right ends of the lower U-shaped body 1. A pressure plate 5 is arranged between the interiors of the two rectangular grooves 4. A clamping block 6 is fixedly connected to the lower end of the pressure plate 5. An arc groove 7 is opened at the lower end of the clamping block 6. A locking mechanism is arranged on the lower side of the pressure plate 5.

[0028] Both ends of the lower U-shaped body 1 are provided with circular holes 12, and the interior of each of the two circular holes 12 is rotatably connected to a steering column 13 that is fixedly connected to the upper U-shaped body 2. A limit mechanism is provided between the lower U-shaped body 1 and the upper U-shaped body 2.

[0029] The limiting mechanism includes first limiting holes 14 respectively opened at the left and right ends of the lower U-shaped body 1, and screws 15 threaded through and connected to the left and right sides of the outer wall of the upper U-shaped body 2. Each of the two screws 15 has a limiting steel column 16 that extends into the two first limiting holes 14 and is adapted to the first limiting holes 14. Each of the two screws 15 has a hexagonal head 17 at the opposite ends. Second limiting holes 19 are opened on the front and rear sides of the two round holes 12.

[0030] In this embodiment: during use, the pipe 3 passes through the interior of the lower U-shaped body 1, and the rubber gasket 8 on the inner wall of the lower U-shaped body 1 is initially attached to the outer wall of the pipe 3, thereby achieving the initial positioning of the pipe 3.

[0031] Then, the locking mechanism provides a downward continuous locking force to the pressure plate 5, so that the rubber gasket 8 on the inner wall of the arc groove 7 of the clamping block 6 is tightly attached to the upper surface of the pipe 3, thereby providing a downward clamping force to the pipe 3. The arc groove 7 and the U-shaped structure of the lower U-shaped body 1 form a two-way enveloping clamp, thereby achieving the purpose of providing an effective clamping force to the pipe 3 and preventing the pipe 3 from slipping due to reciprocating loads.

[0032] When it is necessary to adjust the angle between the upper U-shaped body 2 and the lower U-shaped body 1, the upper U-shaped body 2 can rotate with the steering columns 13 at both ends. When rotating, the upper U-shaped body 2 drives the screw 15 and the limiting steel column 16 to rotate synchronously around the axis of the steering column 13. When the limiting steel column 16 corresponds to the first limiting hole 14 of the lower U-shaped body 1, the upper U-shaped body 2 and the lower U-shaped body 1 are in an up-down distribution state, which is suitable for the top installation of the seismic bracing. When the limiting steel column 16 corresponds to the corresponding second limiting hole 19, the upper U-shaped body 2 and the lower U-shaped body 1 are in a vertical state, which is suitable for the side installation. After the angle is adjusted to the correct position, the hexagonal head 17 of the screw 15 is turned by wrench to drive the limiting steel column 16 to move inward until it is completely embedded in the first limiting hole 14 or the corresponding second limiting hole 19. Since the limiting steel column 16 and the limiting hole are precisely matched, the relative rotation between the upper U-shaped body 2 and the steering column 13 can be effectively restricted, thereby significantly improving the stability of the connection structure.

[0033] As a technical optimization of this utility model, the locking mechanism includes two internally threaded cylinders 9 fixedly connected to the lower end of the pressure plate 5, and perforated plates 10 fixedly connected to both the left and right ends of the lower U-shaped body 1. Bolts 11, which are threadedly connected to the inner walls of the two internally threaded cylinders 9 respectively, are inserted into the interior of the two perforated plates 10.

[0034] In this embodiment: two bolts 11 are threaded through the hole plate 10 and connected to the two internally threaded cylinders 9 at the lower end of the pressure plate 5 to provide a continuous locking force to the pressure plate 5.

[0035] As a technical optimization of this utility model, sliding grooves are provided on both the front and rear sides of the inner walls of the two rectangular grooves 4, and two sliders are installed on both the front and rear sides of the pressure plate 5. The four sliders are slidably connected to the four sliding grooves respectively.

[0036] In this embodiment, the pressure plate 5 is embedded in the sliding groove of the rectangular groove 4 of the lower U-shaped body 1 by the sliders on the front and rear sides, ensuring that the pressure plate 5 can only slide vertically along the rectangular groove 4.

[0037] As a technical optimization of this utility model, the inner walls of the two circular holes 12 are provided with annular grooves, and the interiors of the two annular grooves are slidably connected with annular slide rails that are fixedly connected to the two steering columns 13 respectively.

[0038] In this embodiment, the annular slide rail on the outer wall of the steering column 13 and the annular slide groove on the inner wall of the circular hole 12 can improve the stability of the steering column 13 rotation.

[0039] As a technical optimization of this utility model, the inner wall of the lower U-shaped body 1 and the inner wall of the arc groove 7 are both equipped with rubber gaskets 8 that fit against the outer wall of the pipe 3.

[0040] In this embodiment, two rubber gaskets 8 are provided to facilitate the protection of the pipe 3.

[0041] As a technical optimization of this utility model, each of the two limiting steel columns 16 has a conical guide head on one side of its opposite side.

[0042] In this embodiment: by setting a tapered guide head, it is convenient for the limiting steel column 16 to enter the first limiting hole 14 or the second limiting hole 19.

[0043] As a technical optimization of this utility model, a connecting hole 18 is provided through the upper side of the outer wall of the upper U-shaped body 2.

[0044] In this embodiment, the connection hole 18 facilitates the connection of the seismic bracing and hanger.

[0045] The working principle and usage process of this utility model are as follows: When in use, the pipe 3 passes through the interior of the lower U-shaped body 1, and the rubber gasket 8 on the inner wall of the lower U-shaped body 1 is initially attached to the outer wall of the pipe 3, thereby achieving the initial positioning of the pipe 3.

[0046] The pressure plate 5 is embedded in the sliding groove of the rectangular groove 4 of the lower U-shaped body 1 by the sliders on the front and rear sides, ensuring that the pressure plate 5 can only slide vertically along the rectangular groove 4. Then, two bolts 11 are threaded through the hole plate 10 and connected to the two internal threaded cylinders 9 at the lower end of the pressure plate 5, which drives the pressure plate 5 to move downward along the sliding groove, so that the rubber gasket 8 of the inner wall of the arc groove 7 of the clamping block 6 is tightly attached to the upper surface of the pipe 3, thereby providing a downward clamping force to the pipe 3. The arc groove 7 and the U-shaped structure of the lower U-shaped body 1 form a two-way envelope clamping, thereby achieving the purpose of providing effective clamping force to the pipe 3 and preventing the pipe 3 from slipping due to reciprocating loads.

[0047] When the angle between the upper U-shaped body 2 and the lower U-shaped body 1 needs to be adjusted, the upper U-shaped body 2 can rotate with the steering columns 13 at both ends. The annular slide rail on the outer wall of the steering column 13 slides in conjunction with the annular groove on the inner wall of the circular hole 12 of the lower U-shaped body 1, ensuring stability during rotation. During rotation, the upper U-shaped body 2 drives the screw 15 and the limiting steel column 16 to rotate synchronously around the axis of the steering column 13. When the limiting steel column 16 corresponds to the position of the first limiting hole 14 of the lower U-shaped body 1, the upper U-shaped body 2 and the lower U-shaped body 1 are in an up-down distribution state, which is suitable for seismic bracing. When the upper U-shaped body 2 and the lower U-shaped body 1 are vertically aligned when the limiting steel column 16 corresponds to the corresponding second limiting hole 19, it is suitable for side mounting. After the angle is adjusted, the limiting steel column 16 is driven to move inward by turning the hexagonal head 17 of the screw 15 with a wrench until it is fully embedded in the first limiting hole 14 or the corresponding second limiting hole 19. Since the limiting steel column 16 and the limiting hole are precisely matched, the relative rotation between the upper U-shaped body 2 and the steering column 13 can be effectively restricted, thereby significantly improving the stability of the connection structure.
