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

To explain this in more detail, in a tie cable installed between the opposing retaining plates in the retaining plate installed on the earth wall surface, the tie cable is formed of several strands of PC strands, and each of the PC strands At the end, the adapter and the sealing ring are inserted into the binding groove of the binding head, and the outer surface of the binding head is crimped, and the tie cable binding bracket is integrally bonded to the end of each PC stranded wire and the adapter, and supports the earthen board. The bolts formed at the rear end of the tie-cable fastening brackets are inserted into the mounting holes of the H-beams by fastening the nuts with the nuts protruding from the rear side of the H-beams. To provide a cable tie.

In civil engineering and building construction, earthen boards are installed to prevent earthen walls from collapsing or flowing down by earth pressure. When the earthen board (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 the domestic utility model publication No. 20-1986-1705, the tie tie for pile support is formed in one piece by inserting anchors at both ends of the tie cable. And to form a threaded portion to insert the inlet frame into the beam and bind the nut to the threaded portion to be mounted, and the 'Tie Cable' of the Utility Model Publication No. 20-1987-14932 and the Utility Model Publication No. 20 -'Anchor of tie cable' of 1988-16341 is to be fixed by inserting the anchors on both ends of the tie cable, respectively, and to attach the washer and nut to the threaded portion formed in the anchor to be mounted on the beam.

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. 50-14810 is a synthetic resin layer made of polyethylene or the like on the outer circumference of a PC steel wire cable made of several strands of steel wire and coated on both ends of the PC steel wire cable. Steel wires are exposed by removing the strands, and the sleeves (steel pipes) are pressed and fixed to the outside of the exposed strands of steel wires, and a screw part is formed on the outer circumference of the sleeves (steel pipes) to fasten washers and nuts (screw coupling) It is to be done.

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 resin layer, so it flows in between these openings and gaps. There is a problem that rust occurs in the steel wire by the moisture to weaken the binding force.

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

In the present invention, in a tie cable provided between the earthen boards facing each other from the earthen board provided on the earthen wall surface, the tie cable is formed of several strands of PC strands, and an adapter is provided at each end of each of the PC strands. And the sealing ring is inserted (combined) into the binding groove of the binding head, and the outer surface of the binding head is crimped and the tie cable binding bracket is integrally bonded to the end of each PC stranded wire and the adapter, and the H beam supports the retaining plate. In the mounting hole of the tie cable fastening bracket is formed by inserting the bolt portion formed with the support and tighten the nut protruding to the rear of the H-beam, and the outer side of the nut provides a tie cable binding device to combine the protective cap. I want to do that.

Another object of the present invention is to tighten the PC stranded wire by removing the air gap by crimping the outer circumference of the tie cable tied bracket when the PC stranded wire of the tie cable is fastened to the tie cable tie bracket. It is possible to fasten the bolts formed at the rear end of the tie cable binding bracket together with the support and fasten the nut at the back of the H-beam to install several strands of the tie cable tied to the tie cable binding bracket. The aim of the present invention is to provide a tie cable bundling device that can prevent the PC strands of the tie cable from falling off.
