[0031] It should also be noted that, in the description of the present invention, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections, direct connections, connections through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0032] like Figures 1 to 6 As shown in FIG. 1 , a double-cable support rod assembly structure of the present invention is used to clamp a cable 40, comprising a support rod 10, a cable clamp assembly 20, and a fastening assembly 30. The side wall of the support rod 10 is provided with two circular connecting holes 11, which are coaxially arranged and extend radially along the support rod 10. There are two cable clamp assemblies 20, which are connected to the connecting holes 11. Figure 2 As shown, the cable clamp assembly 20 can rotate around the connection axis; the cable clamp assembly 20 is used to clamp the cable 40. The fastening assembly 30 is connected to the cable clamp assembly 20 to connect the cable clamp assembly 20 to the connection hole 11 to prevent the cable clamp assembly 20 from falling off.

[0033] During construction, the double-cable support rod combination structure of the present invention is applied to the cable node, which can clamp two cables 40 at the same time; in addition, during the construction process, when the stress on the cable 40 changes, the cable clamp assembly 20 can rotate around the axis of the connecting hole 11, thereby adjusting the angle of the cable clamp assembly 20 to improve the stress distribution of the cable node; avoid the formation of excessively large inflection points at the cable node, reduce the difficulty of construction and installation, and be suitable for buildings with larger spans.

[0034] See also Figures 3 to 5 The cable clamp assembly 20 includes a base 21, a pressure cover 22, and a fastening bolt 23. When installing the cable 40, the cable 40 is placed on the base 21, and then the pressure cover 22 is locked to the base 21 using the fastening bolt 23. The cable 40 is clamped between the base 21 and the pressure cover 22. Specifically, a boss 211 is provided at the end of the base 21 facing away from the pressure cover 22. When the cable clamp assembly 20 is connected to the strut 10, the boss 211 cooperates with the connecting hole 11. The boss 211 is cylindrical, so it can rotate within the connecting hole 11, thereby achieving a rotational connection between the cable clamp assembly 20 and the connecting hole 11. At the same time, the boss 211 cooperates with the connecting hole 11 to withstand the axial force of the strut 10. A through hole 212 for structural connection is provided in the base 21 , and a clearance groove 213 is provided on a side of the base 21 facing the pressure cover 22 . The clearance groove 213 is provided around the through hole 212 and extends radially of the through hole 212 .

[0035] Furthermore, a first wire groove 214 is provided on the end of the base 21 facing the gland 22, and a second wire groove 221 is provided on the end of the gland 22 facing the base 21. Both the first wire groove 214 and the second wire groove 221 have semicircular cross-sections. When the gland 22 and the base 21 are assembled, the first wire groove 214 and the second wire groove 221 combine to form a wire passage 24 for accommodating the cable 40. A retaining groove 215 is also provided on the end of the base 21 facing the gland 22. When the gland 22 and the base 21 are connected, the gland 22 is engaged in the retaining groove 215. The retaining groove 215 acts as a limiter for the gland 22 to prevent it from shaking. The base 21 defines a first assembly hole 216, and the gland 22 defines a second assembly hole 222 coaxially disposed with the first assembly hole 216. Both the first assembly hole 216 and the second assembly hole 222 are threaded holes. The fastening bolt 23 passes through the first assembly hole 216 and the second assembly hole 222, respectively, to lock the base 21 and the gland 22. The cable clamp assembly 20 also includes a first washer 25 sleeved around the fastening bolt 23. When the fastening bolt 23 is locked into the gland 22 and the base 21, the first washer 25 abuts against the side of the gland 22 facing away from the base 21. The first washer 25 serves to enhance the locking stability of the fastening bolt 23.

[0036] See also Figure 6 The fastening assembly 30 includes a pin 31 and a locking nut 32. One end of the pin 31 is provided with an integral stopper 311. A second washer 33 is sleeved around the outer side of the pin 31 to enhance connection stability. The pin 31 is inserted into the connection hole 11. Both ends of the pin 31 extend through the connection hole 11 and connect to the cable clamp assemblies 20 on either side.

[0037] During actual assembly, the two bases 21 are clipped onto the two sides of the strut 10 through the cooperation of the boss 211 and the connecting hole 11; then the pin 31 passes through the through hole 212 of the base 21 and the connecting hole 11 of the strut 10 along the radial direction of the strut 10, and the fastening nut is locked into the end of the pin 31 away from the limit head 311, thereby fixing the two bases 21 to the two sides of the strut 10. After the pin 31 is locked, the limit head 311 and the locking nut 32 will be located in the air-avoiding groove 213, avoiding affecting the connection of the cable 40. The cable 40 is then placed on the base 21, and the gland 22 is locked by tightening the bolt 23 to complete the assembly.

[0038] Compared with the prior art, the double-cable strut combination structure involved in the utility model is applied to the design of cable nodes, including a strut, a cable clamp assembly and a fastening assembly; the strut is provided with two connecting holes that are coaxially arranged and extend radially along the strut, and the two cable clamp assemblies are respectively rotatably connected to the connecting holes; the cable is clamped by the cable clamp assembly, and the angle of the cable can change with the rotation of the cable clamp assembly; during the construction process, the angle of the cable clamp assembly changes continuously with the stress change, and can be rotated at any angle at any time to improve the stress distribution condition of the cable node, which is suitable for buildings with larger spans; in addition, the fastening assembly adopts a pin shaft, which on the one hand prevents the cable clamp assembly from falling off, and on the other hand ensures the rotation of the cable clamp assembly. The use of a pin shaft can bring convenience to construction and installation.

[0039] The above merely represents the preferred technical solution of the present invention. While the description is relatively specific and detailed, it should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art may make various modifications and improvements without departing from the concept of the present invention, and the present invention is intended to encompass such modifications and variations.
