the sleeves forming the lock head are respectively arranged at two ends of the steel twisted rope inhaul cable, and a plastic protective sleeve is arranged outside the steel twisted rope between the lock heads.
The utility model provides a pair of bridge beam supports cable tapered end compares with prior art, has following advantage: because one section of the end part of the steel stranded rope in the sleeve of the inhaul cable lock head is in a split and dispersed shape and is arranged in the sleeve, the resin anchoring agent is poured and filled in the sleeve, and the end part of the steel stranded rope and the sleeve are anchored and connected into an integral structure, the inhaul cable lock head formed by pouring the resin has the advantages of quick assembly, high mechanical strength, quick bearing, similar anchoring performance to a steel bar embedded part, large anchoring force, capability of bearing impact load in time, good fatigue strength and strong safety and stability; secondly, the stay cable lock head pouring forming process does not need specially-made or purchased forming equipment, the assembling operation is simple, the stay cable lock head can be assembled immediately after use, meanwhile, the simultaneous pouring operation and standardized operation of a plurality of stay cable lock heads can be realized, the performance stability and consistency of the stay cable lock head assembling are improved, and the standardized requirement of a bridge support product is met.
Drawings
Fig. 1 is the utility model relates to a bridge beam supports's cable tapered end structure sketch map.
Detailed Description
The structure and the working principle of the bridge support inhaul cable lock head provided by the utility model are further described in detail with the accompanying drawings.
Referring to fig. 1, the structure of the cable lock head for forming the bridge support comprises a sleeve 2 for anchoring the end of a steel strand 1, wherein the part of the end of the steel strand 1 in the sleeve 2 is in a split and dispersed shape 11, a resin anchoring agent 3 is poured and filled in the sleeve 2, and the end of the steel strand 1 is anchored in the sleeve 2.
The working principle is as follows: the end part of a steel stranded rope 1 of the inhaul cable is arranged in a sleeve 2 in a penetrating mode, the part, located in the sleeve 2, is subjected to strand breaking, dispersing and cleaning in advance, the length of the part is consistent with that of the sleeve 2, the tonnage and displacement limiting requirements of a corresponding inhaul cable damping bridge are met, a resin anchoring agent 3 is prepared, pouring and filling are carried out in the sleeve 2 until a cavity of the sleeve 2 is filled, one side of the sleeve 2 is sealed and blocked in the pouring process, overflowing is avoided, and the sleeve 2 is kept stand for 8 hours after pouring is finished, so that the optimal mechanical property is achieved.
In the structure of the dragline tapered end of the bridge bearing,
