The present invention relates to a tie-cable binding device used to support a retaining plate which is installed to prevent the earth wall from flowing down or collapsing by earth pressure when excavating in civil engineering and building construction.

In more detail, in a tie cable installed between the opposing retaining plates in the retaining plate installed on the earth wall surface, the ends of the multiple strands of PC strands forming the tie cable are integrally compressed. Tie cable by squeezing the outer surface of the end of the binding head by inserting it into the clip and pressing it to form a unitary body, and inserting a crimping clip in which the ends of each PC strand are integrally inserted into the binding groove of the binding head. Tie the end of each PC strand and the crimping clip in one piece inside the binding bracket, and insert the bolt part formed at the rear end of the tie-cable binding bracket together with the support to the back of the H beam in the mounting hole of the H-beam supporting the retaining plate. It is necessary to provide a tie cable fastening device by fastening a nut to a protruding bolt part and engaging a protective cap to the outside of the nut. .

In civil engineering and building construction, the earth wall is formed by installing the earth plate to prevent the earth wall from collapsing or flowing down by earth pressure. When the earth plate (wall) is not able to withstand (resist) earth pressure, tie cable Reinforce and support the retaining plate (wall) using wire rope, rebar, etc.

As a conventional tie cable used as described above, Korean Utility Model Publication No. 20-1986-1705, Korean Utility Model Publication No. 20-1987-14932, Utility Model Publication No. 20 1988-16341, Utility Model Registration No. 20-277686, Patent Publication No. 10-1990-7120, and Japanese Patent Publication No. So50-14810 are known.

In Korea Utility Model Publication No. 20-1986-1705, 'Tie Cable for Pile Brace' is formed in one piece by inserting anchors at both ends of each tie cable. The thread was formed to bind the inlet frame to the beam, and the nut was attached to the threaded portion. 'Tie cable' of the Korean Utility Model Publication No. 20-1987-14932 and the Korean Utility Model Publication No. 20- 1988-16341 'anchor of tie cable' is to be fixed by inserting the anchors at both ends of the tie cable, respectively, and to be mounted on the beam by fastening the washer and nut to the threaded portion formed on the anchor.

However, they are formed as described above, because the anchors coupled to both ends of the tie cable are fixed to the beam (H beam or wall) by washers and nuts, there is a problem that the binding force between the tie cable and the anchor is weak, so that the bearing capacity is lowered. There is a problem that the anchoring force is separated (detached) to release the binding force.

In addition, the 'removable tie cable' of Utility Model Registration No. 20-277686, each anchor head is inserted into both ends of the strands (tie cable) to be built into the slide pipe, and each projecting to the rear of each anchor head At the end of the stranded wire (tie cable), a wedge formed in a conical shape is fixed and loaded inside the anchor head, but the anchor head mounted on one side of the stranded wire (tie cable) is inserted into the separately mounted fixed mounting head and fixedly mounted. The cap was put on the back of the head.

However, this is a problem that can not be mounted (fixed) on the beam (H beam or wall) because the anchor head and fixed mounting heads mounted on both ends of the strands (tie cables) are located outside the beam (H beam or wall). In order to adjust the length and tension of the stranded wire (tie cable), it is necessary to adjust the position of the wedge that is joined to the end (pull or artificially) while pulling the stranded wire (tie cable) from the outside of the beam (H beam or wall). There is a problem in that the length and tension of the (tie cable) cannot be easily adjusted.

'Tie cable' of Patent Publication No. 10-1990-7120, peels the coating layer at both ends of the PC steel wire cable, and fixes the binding port (binding cup) to the end of the steel wire exposed to the outside by drawing or extruding To the outside of the fastener (coupling cup), the threaded portion is coupled to the sleeve formed on the outer surface, and the sleeve is coupled to overlap the end of the coating layer, and the threaded portion formed on the outer surface of the sleeve is fastened to the washer and nut (screw coupling).

When the steel wires exposed at both ends of the PC steel wire cable are inserted and fixed by drawing or extrusion, the ends of the coating layers are overlapped and bonded to each other so that the sealing force is improved to block the inflow of outside air (humidity). This can prevent the rust from occurring in the steel wires.

However, since the entire steel wire exposed to both ends of the PC steel wire cable is inserted into the interior of the binding port (binding cup) and fixed integrally by drawing or extruding, even if the binding cup (binding cup) is drawn or extruded strongly, A gap (space) is generated between the steel wires inserted into the compressed wires, and when a gap is generated between the steel wires held inside the binding hole (binding cup), the binding force is weakened and the gap is generated due to vibration. In addition, there is also a phenomenon that the separation occurs, there is a problem that the binding force is reduced as rust is generated in the steel wire by the moisture penetrating into the gap generated in this way to corrode.

`` Tie Cable '' of Japanese Patent Publication No. SO 50-14810 forms a synthetic resin layer made of polyethylene or the like on the outer circumference of a PC steel wire cable composed of several strands of steel wire, and covers the synthetic resin layer coated on both ends of the PC steel wire cable. Remove and expose several strands of steel wire, and press and fix the sleeve (steel pipe) to the outside of the exposed multiple strand steel wire, and form a screw part on the outer circumference of the sleeve (steel pipe) to fasten the washer and the nut (screw coupling) It is.

This is because the steel wire is very strong, so even if multiple strands of wire are inserted into the sleeve (steel pipe) and the sleeve (steel pipe) is pressed and fixed with a strong pressure (force), the internal steel wires are connected to each other by point contact, so it is unstable. There is a problem of binding, and each steel wire is inserted into the sleeve (steel pipe) to be bound by a long time due to the unstable binding state, the binding state is weakened by vibrations, etc., the gap is generated while the gap occurs.

In addition, the sleeve (steel pipe) that compresses the steel wire exposed to both ends of the PC steel wire cable has an open type at the rear, and a space is generated between the sleeve (steel pipe) and the synthetic resin layer. There is a problem that rust occurs in the steel wire by the incoming moisture, which weakens the binding force.

In order to solve the above problems, I propose the tie-cable binding device 10 of Patent Application No. 10-2005-22041 as illustrated in FIG.

It forms a tie cable (1) with a plurality of strands of PC strands (2) with a built-in wire steel wire (3), the adapter 20 and the sealing ring (21) is tied to each end of each PC strand (2) The outer surface of the binding head 12 is crimped in the state of being inserted (engaged) into the binding groove 14 of the head 12, and the tie cable binding bracket 11 has an end portion and an adapter 20 of each PC strand wire 2 attached thereto. The bolt hole 13 formed at the rear end of the tie-cable binding bracket 11 is inserted together with the supporter 15 in the mounting hole 7-1 of the H-beam 7, which is integrally bound and supports the retaining plate. The nut 16 is fastened and mounted at the rear of the H beam 7, and the protective cap 18 is coupled to the outside of the nut 16.

However, this is a little cumbersome to insert the adapter 20 and the sealing ring 21 at the end of each PC strand (2), respectively, the binding groove (14) formed inside the tie cable ties (11). ) Is formed too short at the distal end portion, the end of each of the PC strand (2) in which the adapter 20 and the sealing ring (21) is inserted is inserted short, there is a fear that the binding force is dropped, coupled to the end of each PC strand (2) If the adapter 20 is not strongly compressed, the binding force may be reduced.

The present invention is to provide an improved tie-cable binding device to solve the above problems.

The present invention is a tie cable provided between the opposing earth plate in the earth plate installed on the earth wall surface to support the earth plate, wherein the ends of several strands of PC strands forming the tie cable integrally The inside of the crimping clip and crimp to form a unitary body.In the state where the crimping clip combined with the ends of each PC strand is integrally inserted into the binding groove of the binding head, the outer surface of the binding head is crimped.

The fastening nut is mounted to the rear, and the outer side of the nut is to provide a tie cable binding device by combining a protective cap.

Another object of the present invention is to integrally form the ends of the PC strands by integrally inserting the ends of each PC strands into the inside of the crimping clips and compressing them when the PC strands of the tie cables are fastened to the tie cable ties. Load the crimping clip, which is combined to the tip of the integrated PC strand, deeply into the inside of the tie cable ties, and press the outer periphery of the tip of the tie cable ties so that it tightly binds the PC strands by eliminating voids. It is possible to strongly bind PC strands by forming projections on the inner and outer surfaces of the crimping clip, and insert the bolt formed at the rear end of the tie cable binding bracket together with the support to insert the nut from the back of the H beam. Tightly install the multiple strands of the tie cable tied to the tie cable tie bracket by tightening The aim is to provide a tie-cable ties to prevent each strand of PC cable from breaking out.

Still another object of the present invention is to compress the crimping clips fitted on the outside of the caps joined to the ends of the PC strand and the PVC covered on the outside, and crimp the outer periphery of the distal end of the tie cable fastening bracket with the crimping clips inserted Tie cable that doubles the binding to strengthen the compressive force and prevents the outside air and moisture from penetrating into the end of the PC strand and the adapter to prevent rust from occurring at the end of the PC strand and to maintain the binding state.
