Description

One-touch Quick-coupler for Connecting Reinforcing Rods

The present invention relates to a coupler for connecting reinforcing bars, and more particularly, to a coupler having a pair of couplers provided with a plurality of knobs having teeth-shaped protrusions for firmly fixing reinforcing bars, The present invention relates to a one-touch type reinforcing coupler capable of increasing a binding force by a hardening agent as a hardening agent is ruptured by a reinforcing bar by providing a capsule containing a hardening agent in each of the coupler bodies.

Conventionally, in order to connect reinforcing bars for use in concrete structures in various construction sites, reinforcing bars are conventionally bundled and fixed in a double layer structure. However, in this reinforcing bar fixing method, an operator has to wire the reinforcing bars around the reinforcing bars a plurality of times The work is troublesome and the center of the reinforcing bar is not vertical and is not straight, but the strength of the wire is weak, so that it is easily broken and the connection state is released.

In order to solve these problems, reinforcing bars (coupling devices) have been developed and used for easily and firmly connecting reinforcing bars by means other than wires.

However, most of the conventional reinforcing bars are structured by inserting the reinforcing bars into the housing and then screwing the housing into the housing, which is complicated in structure and difficult to connect the reinforcing bars. there is a problem.

In order to solve such a problem, Korean Registered Patent No. 0439305 (registered on June 28, 2004), Korean Registered Patent No. 0462291 (registered on December 2004), Korea Registered Patent No. 1003302, One-touch type reinforcing couplers are disclosed.

The conventional one-touch type reinforcing couplers have a plurality of assemblies for holding reinforcing bars inside the coupler. When the reinforcing bars are inserted, they naturally spread outwardly. When the reinforcing bars are completely inserted, When the tensile force is applied to the reinforcing bar, the wing acts as the wing is supported by the inclined surface of the coupler body so that the reinforcing bar is firmly supported from the coupler body.

However, the conventional one-touch type reinforcing couplers are required to maintain a widened state when the reinforcing bars are inserted, but it is difficult to maintain the predetermined position due to the elastic force of the spring disposed at the lower portion of the fitting. And there is a problem that the verticality of the reinforcing bar is not accurately displayed.

Conventionally, there has been used a method of forming a guide member between the assemblies to maintain the position of the assembled body or to form a receiving groove capable of maintaining its position while inserting the member into the inner surface of the coupler body. However, There is a problem in that an initial slip phenomenon occurs when the tensile force is applied to the reinforcing bars as the guide member interferes with the assembled body and the reinforcing bars escape. When the receiving groove is formed in the coupler body, There is a problem in that it is difficult to form an accurate size and shape.

In addition, since the conventional one-touch type reinforcing couplers fix the reinforcing bars only by the action of a bracket, there is a limit to the binding force, and there is a possibility that the phenomenon that the reinforcing bars are separated from the bracket may separate.

Korean Registered Patent No. 10-0439305 (registered on June 28, 2004) Korean Registered Patent No. 10-0462291 (Registered on December 8, 2004) Korean Registered Patent No. 10-1003302 (Registered on December 16, 2010) Korean Registered Patent No. 10-1259959 (Registered on April 25, 2013)

The first locking member 20a includes a plurality of (four in this embodiment) fixtures 21 and a plurality of fixtures 21 that are in contact with the inner surface of the fixture 21 at the inner side of the space between the fixtures 21 (25) for keeping the gap constant in a state in which the opening (25) is open.

The plurality of fixtures 21 constituting the first locking member 20a are installed in the hollow portion 11 of the upper coupler body 10a and the outer side surface is curved so that the taper portion of the hollow portion 11 12). The brackets 21 have the same shape and their lower ends are coupled to the knitting fastening portions 32 of the first breaking holder 30a to maintain a constant interval. When the reinforcing bars B are not inserted into the upper coupler body 10a, the fixtures 21 are spaced apart from each other by the first fracture holder 30a and the spacing holder 25, When the separating portion 31 of the first breaker holder 60 is inserted through the inlet 11a of the coupler body 10a and is pressed upward by the elastic member 40 to be disengaged, The locking protrusions 22 on the inner side are pressed against the outer surface of the reinforcing bar B to firmly fix the reinforcing bar B.

A plurality of locking protrusions 22 are formed on the inner surface of the fitting body 21 so as to support the rod P of the reinforcing bar B. The locking protrusions 22 are arranged at a constant pitch along the axial direction of the upper coupler body 10a and are provided with a ratchet so as to resist the tensile force applied from the node P of the reinforcing bar B, ) ≪ / RTI > The locking protrusions 22 are preferably formed at a pitch of 1 占 0.05 mm, but may be changed according to the standard of the reinforcing bars.

An engaging projection 23 having a size and shape corresponding to the engaging groove 34 formed in the engaging portion 32 of the first engaging portion 32 of the first breaking holder 30a protrudes downward from the lower end of the body 21 And the coupling protrusion 23 is fitted into the coupling groove 34 so that the coupling protrusion 23 is tightly fitted into the coupling groove 34 so that the lower end of the coupling body 21 is fixed to the knitting fastener portion 32.

The first fracture holder 30a is made of synthetic resin such as plastic. The first fracture holder 30a is installed at a lower side of the fixture 21 and supports the fixtures 21 at regular intervals while the reinforcing bars B are not inserted inside the upper coupler body 10a After the reinforcing bar B is inserted, the center part pressed by the end of the reinforcing bar B and the peripheral part joined with the fitting body 21 are separated from each other so that the fitting body 21 is separated by the first elastic member 40a It acts so that it can be pinched by movement.

4 and 5, the first fracture holder 30a includes a separator 31 which is pressed against the lower end of the reinforcing bar B inserted into the upper coupler body 10a, A flat portion 32 which is arranged at an edge portion of the separating portion 31 at regular intervals along the circumferential direction and into which the lower ends of the respective fittings 21 are inserted and joined, And a breaking portion 33 connecting the tab fastening portion 32 and being cut when the separating portion 31 is pressed downward by the lower end of the reinforcing bar B. [

In this embodiment, the separating part 31 is formed in a flat disk shape, and the breaking part 33 connects the outer peripheral surface of the upper end of the flat binding part 32 and the edge part of the separating part 31.

6, the separating portion 31 is formed in a cylindrical shape with the upper surface thereof being opened and the lower surface thereof being clogged so that the reinforcing bar B is separated from the separating portion 31 through the upper surface of the separating portion 31, It may be inserted into the inner space of the separating portion 31 to press the separating portion 31. At this time, in order to press the separating portion 31 while allowing the lower end of the reinforcing bar B to be accurately guided to the center portion of the separating portion 31, the lower end portion of the separating portion 31 is gradually reduced in diameter toward the lower side It is preferable that a holder tapered portion 37 is formed. This is for the purpose of enabling the reinforcing bars B to be correctly connected to the upper coupler body 10a without being twisted when the reinforcing bars B are inserted into the upper coupler body 10a and connected thereto to improve the vertical degree.

The tab fastening coupling portion 32 of the first fracture holder 30a is a portion for fixing and supporting the lower end of the coupling body 21 and has an arcuate coupling groove 34 are formed, and the individual knitting fasteners 32 are separated from each other. Therefore, when the break portion 33 connecting the single-piece fastening portion 32 and the separating portion 31 is cut, the individual fastening fastening portions 32 are completely separated from each other and become independent.

The lower end of the knit fastening part 32 comes into contact with the upper end of the first elastic member 40a and receives the elastic force of the first elastic member 40a.

The breaking portion 33 connecting the edge portion of the separating portion 31 and the tab fastening portion 32 to each other is formed in a state in which the reinforcing bar B does not press the separating portion 31, It is preferable that the connection portion of the fastening portion 32 is stably maintained and the reinforcing bar B has a shape and thickness that can be easily cut when the separating portion 31 is pressed. Or may be formed in the form of a ring integrally extending along the circumferential direction at the edge portion of the separating portion 31 or a shape in which a plurality of rupture portions 33 are arranged at regular intervals along the circumferential direction on the edge portion of the separating portion 31 .

The thickness of the rupturing portion 33 is preferably smaller than the thickness of the separating portion 31 so that the rupturing portion 33 can be cut smoothly. And may be formed to a thickness of about 20 to 70% of the thickness.

A plurality of auxiliary break grooves 36 extending radially from the center are formed on the upper surface or the lower surface of the separating portion 31 in order to smoothly cut off the break portion 33, 33, respectively.

Since the lower end of the body 21 is connected to and supported by the first breaking holder 30a, when the elastic force of the first elastic member 40a is applied upward, the upper portion of the body 21 is lifted to a certain degree, And the like. In this case, the rebar (B) is caught on the upper end of the body (21), and smooth insertion may not be achieved. Therefore, the space holding tool 25 is inserted into the space between the plurality of the bodies 21 to support the upper or intermediate part of the body 21 so that the body 21 can be maintained in a uniformly open state as a whole. The gap holding tool 25 has a circular ring shape with a hole formed at the center thereof so that the outer edge portion thereof contacts the locking protrusion 22 of the body 21 to maintain the distance of the body 21. When the reinforcing bars B are inserted into the spaces between the assemblies 21, the spacing retaining mouths 25 are inserted into the joints 21 So that the plate body 21 is pinched after the reinforcing bar B is inserted, but it does not interfere with the plate body 21 at all.

The first elastic member 40a is provided between the coupling socket 50 and the first coupling holder 32 of the first coupling holder 30a and is connected to the coupling socket 32 with respect to the coupling socket 50, And the coupling body 21 is urged in the axial direction to push the coupling bodies 21 toward the inlet 11a so that the coupling body 21 is brought into close contact with the tapered portion 12 of the upper coupler body 10a. The first elastic member 40a may be a compression coil spring or the like as in this embodiment, but may also be constructed using a high-elasticity plate spring.

The supporting member provided between the upper and lower coupler bodies 10a and 10b is formed of a connecting socket 50 for integrally connecting the upper coupler body 10a and the lower coupler body 10b to each other.

The connecting socket 50 is in the form of a circular tube having an upper surface and a lower surface opened. The upper end is inserted and coupled through the lower end of the hollow portion 11 of the upper coupler body 10a, The upper coupler body 10a and the lower coupler body 10b are fixed to each other while being inserted through the upper end of the hollow portion 11 of the coupler body 10b. To this end, the upper surface of the connecting socket 50 is provided with an upper male thread 53 and an upper male thread 53 which are respectively connected to the female thread 13 of the upper coupler body 10a and the female thread 13 of the lower coupler body 10b, And a lower male thread 54 is formed.

A partition wall 51 is formed at the center of the inner space of the connecting socket 50 so as to penetrate the through hole 52 vertically. The partition wall 51 serves as a stopper for restricting the insertion position of the reinforcing bar B together with the function of the supporting portion on which the capsule 80 is placed.

When the reinforcing bar is inserted into the upper coupler body 10a, the capsule 80 is ruptured and the hardening agent 82 flows out. At this time, the hardening agent 82 flows through the through hole 52 of the partition wall 51 There is a high possibility that the effect of strengthening the binding force by the curing agent 82 can not be obtained. Therefore, in order to prevent this, it is preferable that the through hole 52 of the connecting socket 50 is fitted with an inner stopper 60 made of an elastic resin such as rubber or silicone to close the through hole 52.

The inner stopper 60 has a fitting portion 61 that is press-fitted into the through hole 52 so as to have a shape and size corresponding to the through hole 52 and a flange portion (62).

In addition, if the concrete flows into the coupler body in which the reinforcing bars B are not inserted, the reinforcing bars B may not be fixed because the fittings 21 are not operated by the concrete. The upper end of the upper coupler body 10a or the lower end of the lower coupler body 10b of the lower coupler body 10b may be connected to the outer cap 11a of the lower coupler body 10b to prevent the inflow of concrete into the coupler body, 70 may be detachably coupled to close the inlet 11a.

The outer stopper 70 may also be made of an elastic resin material such as rubber or silicone. A cylindrical stopper body 71 which is press-fitted into the upper end inlet 11a of the upper coupler body 10a or the lower end inlet 11a of the lower coupler body 10b and a cylindrical stopper body 71 which is inserted into one end of the stopper body 71 in the radial direction And two flange portions 72 which are formed to protrude outward and come into close contact with the peripheral portion of the inlet 11a.

When the flange portion 72 is formed of two vertically spaced apart portions, the outer stopper 70 is press-fitted into the upper end inlet 11a of the upper coupler body 10a or the lower end inlet 11a of the lower coupler body 10b When the outer stopper 70 is dismounted after being closed, the operator can pull out the flange portion 72 of the outer periphery firmly by hand.

The outer surface of the cap body 71 is formed with a plurality of contact protrusions 73 protruding in a ring shape so as to be elastically deformed and attached to the inner circumferential surface of the inlet 11a.

The capsule 80 includes a curing agent 82 made of a one-pack type or two-pack type mortar or resin in a liquid or paste state in a thin resinous shell material 81 that can be easily ruptured by the reinforcing bars B It has a pack form. As the curing agent (82) of the capsule (80), an epoxy resin which is cured at room temperature and has excellent adhesion strength after curing can be used.

The above-configured one-touch type reinforced coupler of the present invention works as follows.

The lower end of the fitting body 21 disposed inside the upper coupler body 10a before inserting the reinforcing bars B into the upper coupler body 10a is inserted into the lower end portion of the fracture holder 30 as shown in Figures 2 and 7A, In a state of being coupled to the fastening portion 32, each of the fixtures 21 maintains a state in which they are spaced at a predetermined interval in the circumferential direction. At this time, the engaging projections 23 at the lower end of the body 21 are inserted into the engaging grooves 34 of the fastening fastening portions 32 in a nearly tight fit state.

The gap holding tool 25 is inserted into the space between the assemblies 21 so that the outer rim thereof is brought into close contact with the locking protrusion 22 on the inner side surface of the body 21 so that the upper portion of the body 21 is constantly opened State.

An inner stopper 60 is attached to the through hole 52 at the center of the partition 51 of the connecting socket 50 and the outer stopper 70 is inserted into the lower end inlet 11a of the lower coupler body 10b The inlet 11a is closed.

When the reinforcing bars B are inserted into the hollow portion 11 through the inlet 11a formed at the upper end of the upper coupler body 10a as shown in Figs. 3B and 7A in this state, And then descends.

The lower end of the reinforcing bar B inserted into the upper coupler body 10a is first pressed against the spacing holder 25 by bumping against the spacing holder 25 of the inner space of the body 21. The lower end of the reinforcing bar B contacts the separating portion 31 of the first breaking holder 30a and presses the separating portion 31 downward. At this time, the bottom of the first breaking holder 30a 32 are supported while being strongly urged upward by the first elastic member 40a so that the breaking portion 33 is cut and the separating portion 31 is moved downward (see FIGS. 3B and 7B). As a result, the knit fastening portions 32 are completely separated and the knit fastening portions 32 and the knitting needles 21 are elastically pressed upward by the elastic force of the elastic members 40, The tabs 12 are pressed against the inner surface of the tapered portion 12, and the tabs 21 are dislocated. As a result, the inner surface of the tubular body 21 is strongly pressed against the outer surface of the reinforcing bar (B).

The gap retaining tool 25 separated from the body 21 by the reinforcing bar B and the separating portion 31 of the first breaking holder 30a collide with the capsule 80 and the outer covering member 81 of the capsule 80 ). The hardening agent 82 flows and hardens after a predetermined time and the lower end of the reinforcing bar B and the fixture 21 are strongly fixed inside the upper coupler body 10a to greatly increase the binding force.

When a force is applied to the reinforcing bar B in the axial direction outer side of the upper coupler body 10a in the state where the reinforcing bars B are inserted into the upper coupler body 10a and a force for separating the reinforcing bars B is applied , The nip P of the reinforcing bar B hits the locking protrusion 22 of the fitting body 21 and presses the fitting body 21 upward. At this time, the tapered portion 12 becomes narrower toward the inlet 11a The joints 21 act as a wedge so that the reinforcing bars B do not come off but are tightly restrained inside the upper coupler body 10a. As described above, the binding force is further increased by the hardening agent 82 flowing out from the capsule 80, and the reinforcing bar B is further tightly restrained inside the upper coupler body 10a.

When the reinforcing bars B are inserted and fixed to the upper coupler body 10a, the concrete is poured and the upper coupler body 10a and the reinforcing bars B are fixed in the concrete. At this time, since the inlet 11a of the lower coupler body 10b is closed by the outer stopper 70, the concrete does not flow into the lower coupler body 10b.

After the reinforcing bars B are connected to the upper coupler body 10a and the concrete is poured, the outer cap 70 is separated from the inlet 11a of the lower coupler body 10b, The reinforcing bars B are inserted from the lower side of the inlet 11a of the body 10b and the reinforcing bars B are connected by pouring concrete.

As described above, when the reinforcing bars B are connected to the upper coupler body 10a and the lower coupler body 10b to connect the reinforcing bars of different diameters, the reinforcing bars B having a size corresponding to the diameter of the reinforcing bar B Coupler bodies can be used in conjunction with each other. At this time, if the connecting socket 50 is replaced with a coupler body of a changed size, it is possible to easily connect reinforcing bars of different diameters.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the present invention as defined by the appended claims. And it is to be understood that such modified embodiments belong to the scope of protection of the present invention defined by the appended claims.
