Description

Tie Cable Binding Device for Tie Cable Binding Device {A Tie Cable Binder For Tie Cable Binding Device}

The present invention relates to a tie-cable ties for a tie-cable binding device, which is 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.

To explain this in more detail, the ends of the PC strands of several strands forming a tie cable are integrally inserted into the crimping clip and pressed to form a single piece, and a crimping clip integrally combined with the ends of each PC strand is formed. In the state of deep insertion (combination) into the binding groove of the tie cable binding bracket, the outer surface of the end of the binding head is crimped to bind the end of each PC strand and the crimping clip integrally to the inside of the tie cable binding bracket. Tie cable which inserts the bolt part formed at the rear end of tie cable fastening bracket together with the support in the mounting hole of H beam and fastens the nut to the bolt part protruding to the back of H beam. In the binding device, a crimping clip integrally coupled to the end of the tie cable is inserted to improve the tie cable fastening bracket. By strengthening the boundary between the binding head where the tie cable is bound and the bolt part that is bound to the H beam, that is, the edge of the boundary step part, the crack occurs at the boundary step between the binding head and the bolt part when the tie cable binding device is installed. To provide a tie cable ties for tie cable ties to prevent the phenomenon of being broken or broken.

In civil engineering and building construction, the earthen wall is formed by installing earthen board to prevent the earthen wall 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 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 the 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 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.

In order to solve the above problems, I propose a tie cable binding device 10 of Patent Registration No. 10-699334 (Patent Application No. 10-2005-22041) as illustrated in FIG.

It forms a tie cable (1) with several strands of PC strands (2) with a built-in wire steel wire (3), and an adapter (not specifically shown) and a sealing ring (specifically) at each end of each PC strand. (Not shown), the outer surface of the binding head 21 is crimped in the state of being inserted (coupled) into the binding groove 24 of the binding head 21, and each PC stranded wire 2 is attached to the tie cable binding bracket 20. The end portion of the coupling unit and the adapter integrally, the mounting hole (7-1) of the H-beam (7) for supporting the retaining plate in the bolt portion 22 formed at the rear end of the tie cable binding bracket (20) support (15) Inserted together with) to fasten the nut 16 from the rear of the H beam (7), and to the outer side of the nut 16 is to combine the protective cap 18.

As shown in FIGS. 2A and 2B, the tie cable binding bracket 20 includes a binding head 21 and a bolt portion 22 integrally formed therein, and the binding head 21 includes a plurality of binding grooves ( 24 is formed concentrically, and the front-end | tip of each binding groove 24 is formed similarly so that the boundary step part 23 may adjoin.

However, when the tie cable 1 is installed to support the retaining plate as illustrated in FIG. 1 by using the tie cable binding bracket 20 formed as described above, the binding force of the nut 16 and the tie cable 1 may be reduced. By the tension, the crack 25 is generated in the boundary step portion 23, which is the boundary line between the binding head 21 and the bolt portion 22, and the edge of each binding groove 24 is adjacent to the boundary step portion 23. Since it is formed in the same way so that pressure cannot be dispersed, cracks are easily generated, and even the boundary step 23 is completely damaged so that the binding head 21 and the bolt 22 are completely separated and the tie cable 1 ), There is a problem of losing the support.

The present invention is to provide a tie cable binding bracket for a tie cable binding device improved to solve the above problems.

The present invention, the end of the strands of PC strands of several strands forming a tie cable integrally inserted into the crimping clip and crimped to form a one-piece, the crimping clip integrally combined with the end of each PC stranded wire tie cable In the state of deeply inserting (coupling) into the binding groove of the binding bracket, press the outer surface of the end of the binding head together to bind the end of each PC strand and the crimping clip integrally to the inside of the tie cable binding bracket, and to support the soil plate. Tie cable bundling device that inserts the bolt part formed at the rear end of tie cable ties together with the support and fastens the nut to the bolt part protruding to the rear of the H-beam, and couples the protective cap to the outside of the nut. The improved tie-k which strengthens the boundary line between the binding head to which the tie cable is bound and the bolt part to be bound to the H beam, ie, the boundary step portion. The aim is to provide tie-cable ties for fastening devices.

Another object of the present invention is to form a boundary line between the binding head to which the tie cable is bound and the bolt portion to be bound to the H beam, that is, a rear part which can enhance the strength of the boundary step portion, and the tie head when the tie cable binding device is installed. The purpose of the present invention is to provide a tie-cable brace that prevents cracking or breakage of the boundary between the bolts.

It is still another object of the present invention to provide a tie cable bundling bracket which is capable of easily forming a rear portion formed between the binding head and the bolt portion, i.e., the outer side of the boundary step portion, by a simple process when forming the tie cable ties. I'm trying to.

Still another object of the present invention is to provide a binding groove formed concentrically on the binding head by zigzag-forming a tip of an adjacent binding groove so that a deviation d occurs, thereby dispersing the pressure applied to the boundary step portion. The aim is to provide a tie-cable brace that prevents the occurrence of

The rear part is integrally formed to reinforce strength,

The boundary line between the binding head to which the tie cable is bound and the bolt part to be bound to the H beam, that is, the rear part which can strengthen the strength of the boundary step part, is formed. Therefore, when the tie cable binding device is installed, the boundary step between the binding head and the bolt part is provided. To prevent cracks or breakage from occurring.

When forming the tie cable binding bracket, the rear portion formed between the binding head and the bolt portion, that is, the outer side of the boundary step portion can be easily formed by a simple process,

The binding grooves formed concentrically on the binding head are formed by zigzag forming the leading ends of the adjacent binding grooves in a zigzag to generate a deviation d, thereby preventing the occurrence of cracks by dispersing the pressure applied to the boundary step. .

The above and other objects and features of the present invention will be more clearly understood by the following detailed description based on the accompanying drawings.

3A and 3B show the tie cable ties 20-1 according to the present invention are formed as follows.

The binding head 21 to which the tie cable 1 is bound and the bolt portion 22 to be bound to the H beam 7 are integrally formed.
