Description

Technical Field

[0001] This utility model relates to the field of building structure technology, specifically to a combined cable clamp for sports stadiums. Background Technology

[0002] A ring cable clamp is a type of clamp that uses friction to fix circumferential and radial cables together, and is widely used in cable-stayed stadiums. Due to its complex structure and relatively large size, the ring cable clamp is difficult to manufacture, which impacts its production cycle and usability. Therefore, there is a need for a cable clamp that can guarantee the anti-slip force between the cable and the clamp while reducing the difficulty of manufacturing, thereby improving production efficiency.

[0025] The advantages of this utility model over the prior art are:

[0026] This utility model relates to a combined cable clamp for sports stadiums, which is a combination structure of the cable clamp main body and the cableway part. The combined structure of the cable clamp reduces the volume of the smallest unit of the cable clamp, reduces the requirements for the model of processing equipment during the processing, and thus reduces the processing difficulty. The combined structure of the cable clamp makes the cableway part universal and interchangeable, which can meet the needs of mass production, and reduces the installation difficulty of the cable clamp and improves construction efficiency.

[0027] This utility model relates to a combined cable clamp for sports stadiums. Fastening devices are added to both ends of the clamp cover plate. The two parts of the cableway are connected as a single unit by the reverse push of bolts. After the cableway is tightened against the limiting platform, it is securely connected to the clamp body by cableway pre-tightening bolts. Therefore, frictional resistance is generated between the cableway and the clamp body, and the limiting platform generates a reaction force on the cableway, overcoming the resultant force of the cable tension. The stable frictional resistance overcomes the difference in cable tension on both sides of the clamp, increasing the anti-slip force and ensuring the clamp's secure fixation of the cable.

[0048] The present invention will now be described in detail with reference to the accompanying drawings and embodiments:

[0049] This utility model relates to a combined cable clamp for sports stadiums. The cableway section clamps the cable through a structure to ensure its anti-slip function. It is then connected to the main body of the cable clamp by a bolt group to form a whole. A limiting platform is used to offset the shear force generated by the circumferential cable in the cableway section, thereby ensuring the safety of the connecting bolts and the stability of the cable clamp assembly structure.

[0050] In the prior art, the cable groove and the cable clamp are integrated into one structure, while in this invention, the cable groove is processed and formed separately.

[0051] like Figure 1 As shown, a combination cable clamp for sports venues,

[0052] Includes: a cable clamp body 1, with limiting platforms 2 respectively provided on the upper and lower surfaces of the cable clamp body 1; and a connecting ear plate 3 provided at the front end of the cable clamp body 1;

[0053] Cableway 4 is provided on the surface of the cable clamp body 1;

[0054] Cableway 4 is connected to cable clamp body 1 via cableway pre-tightening bolts 5;

[0055] Cableway 4 has 6 sections along its length;

[0056] A U-shaped groove 7 is provided in the middle of cableway 4 along the width direction;

[0057] A cable clamp cover plate 8 is provided inside the U-shaped groove 7;

[0058] The lower surface of the cable clamp cover plate 8 is provided with a semi-circular arc groove 9;

[0059] A cable 11 is provided between the cableway arc groove 6 and the cover plate semi-circular arc groove 9;

[0060] The top of cable 11 fits into the semi-circular arc groove 9 of the cover plate;

[0061] The bottom of cable 11 fits into the cableway's curved groove 6;

[0062] The cable clamp cover plate 8 is connected to the cableway 4 via cover plate pre-tightening bolts 10;

[0063] A cable clamp fastening device is provided between the cable clamp cover plate 8 and the inner wall of the U-shaped groove 7.

[0064] Preferably, the cableway 4 is located between two adjacent limiting platforms 2.

[0065] Preferably, the cable clamp cover plate fastening device includes grooves 12 provided at the four corners of the cable clamp cover plate;

[0066] A threaded hole is provided at groove 12 along the horizontal direction;

[0067] A locking nut 13 is provided on the fastening screw 14;

[0068] The front end of the fastening screw 14 is connected to the threaded hole;

[0069] The head of the fastening screw 14 fits against the inner wall of the U-shaped groove 7.

[0070] Preferably, the gap between the lower end face of the cable clamp cover plate 8 and the bottom of the U-shaped groove 7 is 2 to 8 mm.

[0071] like Figure 4 As shown: There is a lateral gap 16 between the side of the cable clamp cover plate 8 and the side of the U-shaped groove 7. The four corners of the cable clamp cover plate have grooves. Adjust the fastening screws at the four corners in sequence to make the cable clamp cover plate and the cableway tightly pressed together.

[0072] like Figure 7 and 8 As shown, in the working state, the cable clamp cover plate and the cable clamp body (i.e., the cableway) are simultaneously subjected to force. Friction prevents the cable from moving. The contact area between the cable clamp cover plate and the cable is smaller than the contact area between the cableway and the cable. The anti-slip force of the cable clamp cover plate is smaller than that of the cable clamp body, so it slips first. The slippage stops after the cover plate and the body are tightly pressed together without any gap in the lateral direction. Therefore, the pre-tightening bolts of the cover plate bear huge shear force, and the entire cable clamp is in an unstable state.

[0073] like Figure 9 There is a gap between the cable clamp cover plate and the side wall of the U-shaped groove of the cableway.

[0074] like Figure 10 Locking screws are installed between the cable clamp cover plate and the side wall of the cableway U-shaped groove, forming an integral structure with the cable clamp cover plate and the cableway U-shaped groove, which is equivalent to eliminating the gap.

[0075] This utility model relates to a combined cable clamp for sports stadiums. A locking nut secures the fastening screws, achieving zero gap between the cable clamp cover plate and the cableway. The resultant force of the cable forces on both sides of the clamp acts on the cableway, causing it to tend to move towards the limiting platform. Since the cableway is then tightened to the clamp body by cableway pre-tightening bolts, frictional resistance is generated between the cableway and the clamp body. The limiting platform then exerts a reaction force on the cableway, overcoming the resultant force of the cable forces. The stable frictional resistance overcomes the difference in cable forces on both sides of the clamp, ultimately achieving secure fixation of the cable by the clamp.

[0076] This utility model relates to a combined cable clamp for sports stadiums, which is a combination structure of the cable clamp main body and the cableway part. The combined structure of the cable clamp reduces the volume of the smallest unit of the cable clamp, reduces the requirements for the model of processing equipment during the processing, and thus reduces the processing difficulty. The combined structure of the cable clamp makes the cableway part universal and interchangeable, which can meet the needs of mass production, and reduces the installation difficulty of the cable clamp and improves construction efficiency.

[0077] This utility model relates to a combined cable clamp for sports stadiums. Fastening devices are added to both ends of the clamp cover plate. The two parts of the cableway are connected as a single unit by the reverse push of bolts. After the cableway is tightened against the limiting platform, it is securely connected to the clamp body by cableway pre-tightening bolts. Therefore, frictional resistance is generated between the cableway and the clamp body, and the limiting platform generates a reaction force on the cableway, overcoming the resultant force of the cable tension. The stable frictional resistance overcomes the difference in cable tension on both sides of the clamp, increasing the anti-slip force and ensuring the clamp's secure fixation of the cable.

[0078] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the structure of the present utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
