In the field of large-span tension structures, cables are often required to be connected with other members through cable clamps as important stressed members, so that the cable clamps are widely applied in the tension structure. When the tension structure is constructed, the existing method is that two rope clamp splints which can be combined together are directly placed at the appointed position of the inhaul cable, the two rope clamp splints are all provided with bolt holes, the two rope clamp splints are directly fixed on the inhaul cable through high-strength bolts, and other components are connected with the rope clamp splints through bolting or welding and other processes, so that a whole stressed together with the inhaul cable is formed. Whether the stay cable and other components of the main body structure can work cooperatively in the tension structure is critical to whether the connection between the stay cable and other components of the main body structure is reliable. In the tensioning process of the prestressed inhaul cable, the cable clamp needs to slide relative to the inhaul cable to a certain extent, and in the normal use process after tensioning, the cable clamp needs to be firmly fixed on the inhaul cable. Whether the prestress inhaul cable is tensioned or the whole structure is normally used, the phenomenon of stress concentration on the surface of the inhaul cable and the abrasion to local inhaul cable wires are prevented. The existing rigid cable clamp can often cause obvious stress concentration phenomenon on the surface of the cable at the edge of the cable clamp and other positions in the two processes, so that the local cable wires of the cable are worn, and once the problem occurs, the cable can not be replaced. To ensure that the inhaul cable fully plays a role, the proper cable clamp device is adopted, so that the phenomenon of stress concentration on the surface of the inhaul cable and the abrasion of local cable wires of the inhaul cable are eliminated, the durability of the inhaul cable and the bearing capacity of the whole structure are directly influenced, and the safety of the whole structure is further influenced.

the upper main clamping plate of the cable clamp and the upper auxiliary clamping plate of the cable clamp are connected with each other in a complementary shape, and are spliced and assembled to form the upper clamping plate of the cable clamp; grooves are respectively arranged on the lower surfaces of the connecting parts of the main clamping plate at the upper part of the rope clamp and the auxiliary clamping plate at the upper part of the rope clamp, the upper grooves are formed after the main clamping plate and the auxiliary clamping plate are spliced, and a soft cushion layer with low friction resistance is adhered on the surface of the upper grooves; the upper clamping plate of the cable clamp is fastened on the upper surface of the inhaul cable through a soft cushion layer with low friction resistance; The upper surface of the rope clamp lower clamping plate is provided with a lower groove, the surface of the lower groove is stuck with a high-friction-resistance soft cushion layer, and the rope clamp lower clamping plate is fastened on the lower surface of the inhaul cable through the high-friction-resistance soft cushion layer; the friction coefficient between the low-friction-resistance soft cushion layer and the inhaul cable is smaller than that between the upper clamping plate of the rope clamp and the inhaul cable, and the friction coefficient of the high-friction-resistance soft cushion layer is larger than that between the lower clamping plate of the rope clamp and the inhaul cable; a gap is formed between the lower surface of the upper clamping plate of the rope clamp and the upper surface of the lower clamping plate of the rope clamp in the area except the groove; a cylindrical space enclosed between the upper main clamping plate of the cable clamp, the upper auxiliary clamping plate of the cable clamp and the lower clamping plate of the cable clamp forms a cable duct; The space of the upper groove is larger than that of the lower groove; the upper surface of the main clamping plate at the upper part of the cable clamp is covered with a cable duct; a plurality of groups of bolt holes perpendicular to the stay cable duct are respectively formed in the upper main clamping plate of the stay cable clamp, the upper auxiliary clamping plate of the stay cable clamp and the lower clamping plate of the stay cable clamp and are positioned at two sides of the stay cable duct; in each group of bolt holes, the bolt hole at one side of the stay rope duct penetrates through the upper main plate of the stay rope clamp and the lower clamping plate of the stay rope clamp, and the bolt hole at the other side of the stay rope duct penetrates through the upper main plate of the stay rope clamp, the upper auxiliary clamping plate of the stay rope clamp and the lower clamping plate of the stay rope clamp; high-strength bolts are arranged in the bolt holes, so that the upper main clamping plate of the cable clamp, the upper auxiliary clamping plate of the cable clamp and the lower clamping plate of the cable clamp are fixed; A connecting piece is arranged on the upper surface of the main clamping plate at the upper part of the cable clamp and is opposite to the position of the inhaul cable, and the connecting piece is connected with the stay bar; In the using process of the tri-petal type cable clamp device, the stay bar transmits pressure to the upper clamping plate of the cable clamp through the connecting piece, the cable bends downwards, at the moment, the upper surface of the cable, namely the surface of the cable, which is contacted with the upper clamping plate of the cable clamp, is a main stress surface of the cable, the upper clamping plate of the cable clamp is a main stress component of the tri-petal type cable clamp device, in the tensioning process, the low-friction soft cushion layer adhered on the surface of the upper groove is equivalent to adding a layer of buffer layer between the cable and the upper clamping plate of the cable clamp, the pressure which is originally locally applied to the cable is dispersed to the surrounding area, the stress area is increased, the larger local stress is effectively reduced, the whole stress of the cable tends to be uniform, the friction coefficient between the low-friction soft cushion layer and the cable is smaller than the friction coefficient between the upper clamping plate of the cable clamp and the cable, thereby reducing the friction resistance of the upper clamping plate of the cable clamp to the cable in the relative sliding process and optimizing the stress of the surface of the cable in the tensioning process; Meanwhile, the high-friction-resistance soft cushion layer adhered on the surface of the lower groove is also equivalent to adding a buffer layer between the inhaul cable and the lower clamping plate of the rope clamp, so that local stress is effectively reduced, and the friction coefficient of the high-friction-resistance soft cushion layer is larger than that between the lower clamping plate of the rope clamp and the inhaul cable, so that the friction resistance of the lower clamping plate of the rope clamp to the inhaul cable is increased, and the two are prevented from sliding relatively within the allowable stress range of the three-flap type rope clamp device.
