Description

Technical Field

[0001] This utility model relates to the field of steel structure connection technology, and in particular to an adjustable cable rod connection clamp. Background Technology

[0002] With the continuous development of the steel structure industry, building structures are becoming increasingly diversified, and complex systems such as cable-stayed structures, suspension structures, tensioned beam structures, and cable domes are being used more and more widely. As the core component for achieving a reliable connection between steel cables, steel tie rods, and the main structure, the performance of the connecting clamps is directly related to the safety and stability of the overall project.

[0003] Currently, traditional cable-stayed rod connection clamps are mostly fixed structures with limited length and angle adjustment capabilities, making it difficult to adapt to different spatial positions and connection angle requirements. Especially at cable-stayed rod nodes with cross arrangements, it is often impossible to effectively stagger or flexibly adjust the connection position, resulting in low installation efficiency, poor adaptability, and limitations on the design and construction of complex structures, as well as poor installation accuracy and adaptability. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide an adjustable cable rod connection clamp.

[0005] The present invention adopts the following technical solution: An adjustable cable rod connecting clamp includes a first pipe clamp assembly, a second pipe clamp assembly, a connecting screw, and two locking nuts. The first and second pipe clamp assemblies have identical structures, and each assembly has a coaxially arranged pivot hole on its opposite side. Both ends of the connecting screw extend into the pivot holes on both sides, and the connecting screw is clearance-fitted into the pivot holes. The two locking nuts are threaded onto both ends of the connecting screw to achieve mutual locking of the first pipe clamp assembly, the second pipe clamp assembly, and the connecting screw. The first pipe clamp assembly and the second pipe clamp assembly are capable of rotating relative to each other about the axis of the connecting screw to adjust the relative angle between the first pipe clamp assembly and the second pipe clamp assembly; the first pipe clamp assembly and the second pipe clamp assembly are capable of moving along the axis of the connecting screw to adjust the relative distance between the first pipe clamp assembly and the second pipe clamp assembly.

[0006] Preferably, the first pipe clamp assembly and the second pipe clamp assembly have the same structure; the first pipe clamp assembly includes an upper pressure block, a lower pressure block and a locking assembly; the upper pressure block and the lower pressure block are arranged opposite each other and are locked to each other by the locking assembly to jointly clamp the cable rod.

[0007] Preferably, both the upper pressure block and the lower pressure block have a semi-circular arc-shaped structure.

[0008] Preferably, the upper pressure block has integrally formed upper connecting arms extending from both sides, and the lower pressure block has integrally formed lower connecting arms extending from both sides; the locking assembly is assembled on the upper connecting arms and the lower connecting arms to achieve mutual locking of the upper pressure block and the lower pressure block.

[0009] Preferably, both the upper and lower connecting arms have semi-circular protrusions at their ends; when the upper and lower pressure blocks are closed, the upper and lower connecting arms fit together, so that the two protrusions are joined together to form the pivot hole.

[0010] Preferably, both the upper and lower connecting arms are provided with clearance grooves that communicate with the pivot hole, and the clearance grooves are used to accommodate the end of the connecting screw and the locking nut.

[0011] Preferably, the clearance groove is arranged in a rectangular structure.

[0015] The beneficial effects of this utility model are as follows: The adjustable cable rod connecting clamp of this utility model is provided with a first pipe clamp assembly, a second pipe clamp assembly, and a connecting screw. The first and second pipe clamp assemblies are respectively connected to the two ends of the connecting screw. The first and second pipe clamp assemblies can rotate relative to each other about the axis of the connecting screw, flexibly adjusting the included angle between them. They can also move along the axial direction of the connecting screw, freely adjusting the spacing. This effectively adapts to the needs of cable rod cross-connections at different angles and distances, greatly improving the applicability and installation flexibility in complex steel structure systems.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or a connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0021] like Figures 1 to 5 As shown, the adjustable cable rod connecting clamp of this utility model includes a first pipe clamp assembly 10, a second pipe clamp assembly 20, a connecting screw 30, and two locking nuts 40. The first pipe clamp assembly 10 and the second pipe clamp assembly 20 have the same structure. The first pipe clamp assembly 10 and the second pipe clamp assembly 20 are respectively provided with coaxially arranged pivot holes 14 on opposite sides. The two ends of the connecting screw 30 extend into the pivot holes 14 on both sides, and the connecting screw 30 and the pivot holes 14 are clearance fit. The two locking nuts 40 are respectively threaded to the two ends of the connecting screw 30 to realize the mutual locking of the first pipe clamp assembly 10, the second pipe clamp assembly 20, and the connecting screw 30.

[0022] In actual construction, the first pipe clamp assembly 10 and the second pipe clamp assembly 20 respectively clamp different cable rods 50. The first pipe clamp assembly 10 and the second pipe clamp assembly 20 can rotate relative to each other about the axis of the connecting screw 30, and can also move along the axial direction of the connecting screw 30, thereby adjusting the included angle and spacing of the first pipe clamp assembly 10 and the second pipe clamp assembly 20 to adapt to the cross-connection requirements of cable rods 50 at different angles and distances. Among them, the clearance fit between the pivot hole 14 of the first pipe clamp assembly 10 and the connecting screw 30 effectively ensures the freedom of movement of the first pipe clamp assembly 10 and the second pipe clamp assembly 20. In this embodiment, the locking nut 40 is a hexagonal nut. After the assembly of the first pipe clamp assembly 10, the second pipe clamp assembly 20 and the connecting screw 30 are completed, the locking nut 40 is screwed into both ends of the connecting screw 30 with a wrench to lock the first pipe clamp assembly 10 and the second pipe clamp assembly 20 and prevent shaking.

[0023] The structure of the first pipe clamp assembly 10 and the second pipe clamp assembly 20 will be described in detail below. Since the structure of the first pipe clamp assembly 10 and the second pipe clamp assembly 20 is the same, only the first pipe clamp assembly 10 will be described to avoid redundancy.

[0024] The first clamping assembly 10 includes an upper pressure block 11, a lower pressure block 12, and a locking assembly 13. The upper pressure block 11 and the lower pressure block 12 are arranged opposite each other and locked together by the locking assembly 13 to clamp the cable rod 50 and apply pressure to the cable rod 50, thereby fixing and clamping it. The upper pressure block 11 and the lower pressure block 12 are both semi-circular arc structures. The upper pressure block 11 and the lower pressure block 12 close together to form a circular clamping space to accommodate the cable rod 50 with a circular cross-sectional shape.

[0025] Specifically, the upper pressure block 11 has integrally formed upper connecting arms 111 extending from both sides, and the lower pressure block 12 has integrally formed lower connecting arms 121 extending from both sides. This increases the connection area between the upper pressure block 11 and the lower pressure block 12, and provides assembly space for the locking assembly 13, thus better achieving mutual locking between the upper pressure block 11 and the lower pressure block 12. In addition, the ends of both the upper connecting arms 111 and the lower connecting arms 121 are provided with semi-circular bosses 112. When the upper pressure block 11 and the lower pressure block 12 are closed, the upper connecting arms 111 and the lower connecting arms 121 fit together, so that the two bosses 112 are joined to form the aforementioned pivot hole 14. Furthermore, both the upper connecting arm 111 and the lower connecting arm 121 are provided with clearance grooves 113 that communicate with the pivot hole 14. The clearance grooves 113 provide accommodating space for the ends of the connecting screw 30 and the locking nut 40. The two ends of the connecting screw 30 extend into the clearance grooves 113 after passing through the pivot hole 14. Then, the locking nut 40 is extended into the clearance grooves 113 and screwed onto the connecting screw 30. In this embodiment, the clearance grooves 113 are rectangular in shape to ensure sufficient space for the locking nut 40 to rotate. At the same time, the upper connecting arm 111 is provided with a first locking hole 114 for mounting the locking assembly 13, and the lower connecting arm 121 is provided with a second locking hole 122 for mounting the locking assembly 13. The first locking hole 114 and the second locking hole 122 are coaxially arranged.

[0026] Specifically, in this embodiment, there are four sets of locking components 13, symmetrically distributed in pairs on both sides of the upper pressure block 11 and the lower pressure block 12. Each locking component 13 includes a locking bolt 131, a locking nut 132, a spring washer 133 located at the top of the upper connecting arm 111, and a flat washer 134 located at the bottom of the lower connecting arm 121. When locking the upper pressure block 11 and the lower pressure block 12, the locking bolt 131 passes sequentially through the spring washer 133, the first locking hole 114, the second locking hole 122, and the flat washer 134. Then, the locking nut 132 is screwed onto the end of the locking bolt 131 and abuts against the outer surface of the flat washer 134. In this embodiment, the locking bolt 131 is a hexagonal head bolt, and the spring washer 133 is used in conjunction with the hexagonal head bolt. When the hexagonal head bolt is tightened, the standard spring washer 133 is compressed and undergoes elastic deformation, effectively preventing the nut from loosening and providing an anti-loosening function. The flat washer 134 is used to increase the contact area and prevent the lower surface of the lower pressure block 12 from being scratched when the locking nut 132 is tightened.

[0027] Compared to existing technologies, the adjustable cable rod connecting clamp of this utility model is provided with a first pipe clamp assembly 10, a second pipe clamp assembly 20, and a connecting screw 30. The first pipe clamp assembly 10 and the second pipe clamp assembly 20 are respectively connected to the two ends of the connecting screw 30. The first pipe clamp assembly 10 and the second pipe clamp assembly 20 can rotate relative to each other about the axis of the connecting screw 30, flexibly adjusting the included angle between them. They can also move along the axial direction of the screw, freely adjusting the spacing. This effectively adapts to the cross-connection requirements of cable rods 50 at different angles and distances, greatly improving the applicability and installation flexibility in complex steel structure systems. At the same time, the locking nut 40 and the synergistic effect of multiple locking assemblies 13 ensure the structural stability and anti-loosening ability of the connection point, enhancing the overall safety. Both the first pipe clamp assembly 10 and the second pipe clamp assembly 20 adopt an upper pressure block 11 and a lower pressure block 12 with a semi-circular arc structure to ensure that they fit in close contact with the surface of the cable rod 50. Combined with a uniformly distributed locking force, this effectively reduces stress concentration and avoids damage to the cable rod 50.

[0028] The above description merely illustrates the preferred technical solution of this utility model, and while the description is relatively specific and detailed, it should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and this utility model also intends to include these modifications and variations.
