Description

Technical Field

[0001] The present application relates to the technical field of engineering building materials, and in particular to an anchor cable assembly and an anchor cable connector. Background Art

[0002] In construction projects, anchor cables are used for anchor support. The main cable is divided into many steel bundles and anchored in anchor ingots. These steel bundles are called anchor cables. The anchor cable is fixed to the slope surface through the outer end, and the other end is anchored in the stable rock mass within the sliding surface. The prestressed steel strands passing through the sliding surface of the slope directly generate anti-slip resistance on the sliding surface, increase the anti-slip friction resistance, and put the structural surface in a compressed state to improve the integrity of the slope rock mass, thereby fundamentally improving the mechanical properties of the rock mass, effectively controlling the displacement of the rock mass, and promoting its stability, so as to achieve the purpose of regulating the layer, landslides, and dangerous rocks.

[0003] Anchor cables are used in most construction projects. Currently, most existing anchor cables are generally integral steel cable structures, which are prone to rust and heavy in weight during use. Steel anchor cables are not easy to cut, which causes obstacles in subsequent excavation construction, reduces the usability of the equipment, and is not conducive to the normal use of the equipment. Improvements are needed. At the same time, steel anchor cables are prone to rust, and anti-rust measures need to be taken, which increases a lot of costs. The use of composite anchor cables can avoid the problems of steel anchor cables being prone to rust and difficult to cut, but the shear force of composite anchor cables is not strong and is not suitable for tensioning. The utility model solves the above problems by combining the composite anchor cable at the anchoring end and the steel strand at the tensioning end. Utility Model Content

[0023] Specifically, the anchor cable connector 300 includes a first connector 310 and a second connector 320. The first connector 310 may be a tubular structure, the first rope 100 is inserted into one end of the first connector 310 and connected to the first connector 310, and the other end of the first connector 310 is provided with a connecting screw 330. The connecting screw 330 may be an integral structure with the first connector 310, or an independent structure, which is screwed with the inner wall thread 311 of the first connector 310, and is not specifically limited here. Optionally, in order to ensure the overall strength of the anchor cable connector 300, in this embodiment, the first connector 310, the second connector 320 and the connecting screw 330 may all be made of steel.

The connecting screw 330 cooperates with the thread 321 to realize the connection between the first connecting member 310 and the second connecting member 320, thereby realizing the connection between the first rope 100 and the second rope 200.

[0025] Optionally, the first rope 100 and the second rope 200 in this embodiment may both be steel strands, and the first rope 1000 and the second rope 200 may both be composite materials. Alternatively, the first rope 100 may be a steel strand and the second rope 200 may be a composite material; or the second rope 200 may be a steel strand and the first rope 100 may be a composite material. The composite material may be a glass fiber composite material, a carbon fiber composite material, a basalt composite material, etc. The features of this part are within the scope of understanding of those skilled in the art and will not be listed and described in detail here.

[0026] Optionally, see Figure 3In this embodiment, the first rope 100 may be bonded and fixed to the inner wall of the first connector 310, wherein the first rope 100 may be a composite material. In order to improve the bonding strength between the first rope 100 and the inner wall of the first connector 310, the inner wall of the first connector 310 may be completely covered with threads 311, and the bonding reliability between the first rope 100 and the inner wall of the first connector 310 may be improved by increasing the bonding area. In addition, the first rope 100 in this embodiment may fill the middle cavity of the first connector 310, and the end of the first rope 100 is supported on the connecting screw 330 and bonded and fixed to the end face 311 of the connecting screw 330, that is, in this embodiment, the first rope 100 is bonded to the inner wall of the first connector 310 through the side, and the top is bonded to the end 311 of the connecting screw 330, further improving the bonding reliability between the first rope 100 and the first connector 310.

Similarly, the inner wall of the second connector 320 is completely covered with threads 321, and the bonding reliability between the second rope 200 and the inner wall of the second connector 320 is improved by increasing the bonding area. In addition, please continue to refer to Figure 3 When the second connecting member 320 is connected to the first connecting member 310, the second rope 200 can fill the central cavity of the second connecting member 320 (except the remaining part for connecting with the connecting screw 330), thereby increasing the connection length between the second rope 200 and the inner wall of the second connecting member 320 and improving the reliability of bonding and crimping.

[0028] The purpose of the anchor cable assembly in the embodiment of the present application is to solve the shortcomings of the prior art that most anchor cables are not easy to cut (all steel strands), are easy to rust, have high manufacturing costs, are heavy, and are not easy to use, which is not conducive to the normal and widespread use of anchor cables. A cuttable (at least one side of the rope uses a composite material) prestressed tensioned anchor cable assembly is proposed. The anchoring end of the anchor cable assembly can use a composite anchor cable, which has the advantages of being cuttable and rust-proof. The tensioning end can use a steel strand, which avoids the disadvantage of the composite anchor cable having weak shear force. The anchor cable assembly structure in the embodiment of the present application meets the overall use strength while realizing the convenient disassembly of the anchor cable, solving the problems of the anchor cable structure in the conventional solution that is difficult to cut, easy to rust, and heavy, greatly improving the installation and recovery availability of the anchor cable, and having a very high use value.
