Description

Reinforcing bar coupler {Reinforcing bar coupler}

The present invention relates to a reinforcing bar connector, and more particularly, the connection work of reinforcing bars that form a skeleton in reinforced concrete construction or the connection of various rods in a construction work is convenient and quick, so that the workability is excellent and the joints are secured. The present invention relates to a reinforcing bar connector which is excellent and economically capable of greatly reducing manufacturing costs by using steel sheet material.

First, as a method of connecting reinforcing bars, some of the typical methods used so far include overlap joints, gas welding joints, and screw joints. Among them, the most common method is overlapping reinforcing bars in parallel with a ties. As a joint method, this method is very fragile in tensile load, and the gas welding joint is a method of joining by pressurizing with the end of reinforcing bar and heating with oxygen acetylene gas flame, which is cumbersome and time-consuming, There is a problem such that the connection part has to be lowered and the connection part should be inspected by ultrasonic method. Difficult to work on, already reinforcement cannot be threaded, long rebar Becomes thinner by a straight line aligning with the difficult task of screw threaded connections are threaded in height than the original, there is a reinforcement of reinforced weakening problems than the tensile strength of the reinforcing original.

In order to solve the problems of the conventional reinforcing bar connection method as described above, the reinforcing bar connection method filed by the applicant of the present invention and registered under registered utility model No. 308578 (name of the design: reinforcing bar connector), one side is completely in the axial direction Consists of the removed open sleeve, node piece, and wedge to connect the two rebars.The inner side of the sleeve is visually seen when connecting the reinforcing bars when the rebar is connected by making all of the sleeves open in the axial direction, leaving only the hooks. It is convenient to work, and it is possible to mass-produce by press using steel plate material, which can greatly reduce the production cost. Also, by connecting two reinforcing bars side by side in a place where rebar joint is required, the connection part of rebar is It is more rigid than overlapping joints by ties. However, in the rebar connector filed by the applicant of the present invention, as shown in FIGS. 46 to 48, two rebars 1 and 1a are installed side by side in the sleeve 2, and the wedge 4 is press-fitted and fixed. Since the bottom of the wedge (4) is flat, even if the diameter of the two reinforcing bars (1, 1a) is the same standard, if there is a slight deviation or if one bar is bent, the rebar can not be pressed at the same time, the play may occur In the inner bottom of the sleeve 2, the node grooves 27 into which the bars 12 of the reinforcing bars 1 and 1a are fitted are formed on the inner surfaces of the two reinforcing bar parts 22, respectively, but the two bars are respectively opposite to each other. In the part where they are sequentially connected to the rebar connector and meet each other, the fixed reinforcement cannot be adjusted in the longitudinal direction so that the nodes 12 of the two bars (1, 1a) can be simultaneously inserted into the node grooves 27 of the sleeve 2. Sometimes there will be no. In addition, when the two reinforcing bars (1, 1a) do not meet in a straight line and intersect, the structure is unable to join the intersection portion, the rib 11 of the two bars (1, 1a) toward the bottom of the inside of the sleeve (2) Even when it is turned, the bar of the reinforcing bar is not fitted into the nodular groove 27 of the sleeve 2 and may slip away even if the wedge 4 is driven.

In particular, until now, the two bars are orthogonally joined and fixed by binding lines so that the connection part is structurally weak. Therefore, the reinforcement of the reinforcing bar itself makes a strong structure. Only the method ensures the safety of the structure during the curing period when the concrete is completely cured.

Next, as a connecting method of rods, bolts and nuts are used for fixing clamps for installing two steel pipes in parallel or intersecting integrally, or for automatic clamping that can be used for cross angles. This method uses screw fastening method, which requires a lot of assembly and dismantling time because the clamp is fixed by screw type, and it is very tedious and inferior in workability to work while rotating and pressing the screw using a tool such as spanner. Even if the bolts are rusted or the concrete is only a little attached, there is a problem that the fastening or disassembly of the nut is difficult or not, and there is a limit to repeated use.

The purpose of the present invention is to register two applications of overlapping reinforcement only by the sleeve and wedge as shown in FIGS. 46 to 48 in the registered utility model No. 308578 filed by the applicant of the present invention (design name: rebar connector) In addition to the structure, the bottom surface of the wedge is formed to protrude long along the longitudinal axis, so that even if the diameter of the two bars is the same size, even if there is a slight deviation or one bar is bent, both bars can be pressed. Saw blade-shaped tooth surface is additionally formed on the bottom surface which is in contact with the outer circumferential surface of the reinforcing bar. When two bars to be connected are fixed without flowing in the axial direction, the bar of one bar does not fit into the sleeve groove of the sleeve. To prevent them from slipping off, and not to tie the intersection of the two reinforcing bars, It strengthens the safety of the reinforcement process and adds to the support method of the existing support during the casting and curing period of the concrete, rather than binding the two reinforcements together and temporarily tying them together only by the binding line. have.

Another object of the present invention is to install a reinforcing member, such as a bolt having a certain height on the bottom surface of the sleeve to float the reinforcement from the floor at regular intervals without a separate spacer as in the prior art by placing concrete enough on the floor to cover the thickness When the formwork top is the ceiling of a building, the socket is formed by tightening the female threaded socket so that the air conditioning duct facility, lighting system, ceiling device, sprinkler facility, piping, etc. can be easily installed in the socket after removing the formwork.

Another object of the present invention is to save the assembly and dismantling time by simply fixing the clamping method of connecting the steel pipes or integrally joining the intersections in the construction work with the sleeve and wedge only when installing a temporary material such as steel pipe scaffolding It is easy to assemble and dismantle only by hammer, and even if concrete is attached to the sleeve or wedge, it is easily detached by vibration caused by the hammer's blow, so as to meet the characteristics of the construction site aiming for convenience and safety of work.

Another object of the present invention is to manufacture the parts of the reinforcing bar by using a steel sheet material by plastic processing to provide a mass production per unit time, and to provide a great economic savings in the manufacturing cost, and to connect the reinforcing bars It is to replace the two reinforcing bars simply and securely.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 to 9 is a first embodiment of the present invention, consisting of a sleeve (2) and a wedge (4) is open on the entire surface of the rebar connector that can be connected in parallel overlapping the ends of the two rebar (1, 1a) Indicates.

The sleeve 2 has a cylindrical shape in which one surface is entirely open in the axial direction and the inside is exposed, and the inner surfaces of the reinforcing bars 1 and 1a are fitted so that the two rebars 1 and 1a can be inserted in parallel with each other in parallel. Reinforcing bar insertion portion 22 having a semi-circular cross section having an inner diameter corresponding to the outer diameter of the section 12 is formed in two parts adjacent to each other in parallel in the transverse direction, and both ends of the transverse direction of the two rebar insertion portions 22 are fishing. A hook ring 23 having an inclined surface 23a bent in the form of a needle and inclined at a predetermined angle in the axial direction is formed in two parts, so that the hook ring 45 of the wedge 4 described later is interlocked and pressed It works.

As shown in FIG. 1, the sleeve 2 has a rebar latching tooth surface 22c formed of a saw blade-shaped protrusion on the inner bottom of the two reinforcing bar insertion portions 22, and the reinforcing bars 1 and 1a are fitted therein. ), Even if tensile force is applied, it prevents slipping easily. Although not shown, the inner bottom surfaces of the two reinforcing bar insertion parts 22 may be knurled to form a plurality of quadrangular pyramid-shaped protrusions, which have the same effect. Also, in order to prevent sliding of the reinforcing bar, as shown in FIG. 8, a plurality of nodular grooves 27 are provided at the same interval as the reinforcing bar 12 so that the bar 12 of the reinforcing bar may be fitted to the inner bottom of the sleeve 2. Although not formed and illustrated, the inner surface between the nodular groove 27 and the nodal groove 27 forms a sawtooth-shaped tooth surface to press the outer peripheral surface of the reinforcing bar so that the reinforcing bars 1 and 1a cannot be easily separated from the sleeve 2. do.

The sleeve 2 has a function of increasing the tensile strength by the adhesion of concrete by forming a through hole 25 penetrating the inside and the outside so that the mortar is introduced into and attached to the outer surface of the rebar. Although not shown, the wedge 4 may also form such a hole.

As shown in FIG. 8, the sleeve 2 has an internal longitudinal axis groove 27b formed of a recess in which the ribs 11 of the rebars 1 and 1a are fitted in the axial direction on an inner bottom surface of the two rebar insertion portions 22. This is formed so that the rib 11 can be inserted when the reinforcing bar fitted to the inner surface of the reinforcing bar insertion portion 22 is inevitably rotated to be installed. However, when the sleeve 2 is processed into a press using an iron plate material to form the node grooves 27 and the inner longitudinal grooves 27b, ribs 21 and nodes 21a are formed on the outer surface at the same position by a mold. To improve adhesion to concrete.

As shown in FIG. 7, in the sleeve 2, a sawtooth surface 23b is formed on the inclined surface 23a formed on the bottom surface of the engaging ring 23 to form a sawtooth surface 45b of the wedge 4 described later. ) Is interlocked with the sleeve to prevent the wedge 4, which is fitted into the sleeve and presses the reinforcing bar, from falling out.

As shown in FIG. 9, the radiuses of the two reinforcing bar portions 22 of the sleeve 2 may be different from each other to connect two reinforcing bars 1 and 1a having different diameters.

The wedge 4 has an elongated plate shape, and both ends in the lateral direction are bent in the form of a fishing needle in one direction so that two hook rings 45 are formed, and the sleeves axially on both end surfaces of the hook rings 45. The inclined surface 45a inclined at the same angle as the inclined surface 23a of 2) is formed, and the widths of the two hooks 45 are formed at equal intervals so as to be fitted to the two hooks 23 of the sleeve 2. do. On the end surface of the inclined surface 45a, as shown in FIG. 7, a toothed surface 45b having a saw blade shape is formed and interdigitated with the tooth surface 23b of the sleeve 2 to be pressed into the sleeve 2. Falling in the reverse direction can be prevented.

The wedge 4 is formed in the diameter of the two reinforcing bars (1, 1a) of the same standard by forming a bottom projection (44) protruding in the V-shape in the direction of the bottom surface 43 in the axial direction along the center line in the transverse direction If the bottom surface 43 is flat when there is a deviation or bending, the inside of the two rebars is compensated for not sufficiently pressing one of the two rebars 1 and 1a even when the wedge 4 is pressed into the sleeve 2. The outer peripheral surface in the direction to be pressed.

The wedge (4) is formed on the striking portion 42, which is the end of the high inclination of the catching ring 45 to form a striking projection (42a) protruding in a V-shape from the bottom surface 43 to the outer surface direction, such as a hammer Facilitates the blow operation.

The wedge 4 is a long end along the bottom line of the hook 45, starting from the tip portion 41, which is a portion that is first introduced into the sleeve 2 as the end of the lower slope of the two hooks 45 The cut portions 45c are formed to press the wedges 4 into the sleeves 2 to press the two reinforcing bars 1 and 1a, and the bent portions 45c are laterally bent, respectively, and the wedges are reversed. You will not retreat.

Although not shown, the outer surface of the sleeve 2 and the wedge 4 is marked with an arrow to indicate the press-in direction of the wedge 4 so that the operator can easily assemble it, starting from the hitting portion on the outer surface of the wedge 4 at a predetermined interval. When connecting the bars of the same standard by displaying the ruler and the sequence number, the depth to be pressed into the sleeve (2) can be observed while watching the ruler to the depth that meets the standard to prevent the reinforcing of the reinforcing bar connection and to facilitate the supervision work. Uplift.

Referring to the operation of the first embodiment of the present invention configured as described above in detail by the coupling sequence as follows.

The front ends of the two reinforcing bars 1 and 1a to be connected overlap the inner surfaces of the two reinforcing bar parts 22 of the sleeve 2, and the wedge 4 is inserted into the hook 21 of the sleeve 2 with a high inlet. When the catching ring 45 of the tip end 41 is introduced into the inside of the side first, and hits the driving protrusion 42a with a tool such as a hammer, it is driven or pushed into the hydraulic press fitting mechanism. The inclined surface (23a) formed in the inclined surface and the inclined surface (45a) formed on the engaging ring 45 of the wedge (4) is sliding and contact with each other so that the bottom surface 43 of the wedge (4) is the inner surface of the sleeve (2) The steel bars 1 and 1a sandwiched between the two steel bars 1 and 1a are strongly pressed and connected to each other. In addition, by increasing the overlap length of the two reinforcing bars (1, 1a) by applying two or more connectors as shown in Figure 3, a stronger joint can be obtained.

10 to 14 is a second embodiment of the present invention, the configuration of connecting the reinforcing bars (1, 1a) only by the open sleeve (2a) and the wedge (4a) is the same as the first embodiment, the sleeve (2a) Transverse width of the opening portion 24 by forming the reinforcing bar insertion portion 22 of the c) as long as the transverse width where the outer circumferential surface of the rebar fits snugly on the inner surface and the length of the reinforcing bar insertion portion 22 is long enough to allow the two rebars to overlap each other. The reinforcing bar is slightly larger than the outer diameter of one bar, and the height of the sleeve 2a is characterized by being formed to the length of overlapping two bars, and the other structure is the same as in the first embodiment.

The wedge 4a forms a transverse width so as to correspond to the sleeve 2a in which the transverse width is adapted to the width of one of the rebars, and the rest of the structure is the same as in the first embodiment.

As shown in FIG. 14, the inner space of the reinforcing portion 22 of the sleeve 2a is made smaller in diameter and made larger in diameter so that the two reinforcing bars can be connected in different diameters. If the inner space of the part 22 is made larger in diameter and smaller in diameter, the inner space of the part 22 can be pulled only in the axial direction when the large diameter rebar is inserted into the sleeve 2a. Do.

The operation and coupling sequence of the second embodiment of the present invention configured as described above is the same as the first embodiment of the present invention, and only the engaging positions 23 and 45 of both hooks 23 and 45 of the sleeve 2a and the wedge 4a. Is located on the side of the reinforcing bar (1a) of one of the two rebar (1, 1a) can be used when the reinforcing connector of the first embodiment is difficult to apply due to the interference of the reinforcing bar is structurally. However, if you want to connect the reinforcing bars with different diameters by the sleeve (2a) and the wedge (4a) shown in FIG.

15 to 20 is a third embodiment of the present invention, unlike the first embodiment to the second embodiment does not have a structure that connects the ends of the two reinforcement in parallel and integrally the part where the two reinforcing bars cross vertically It is formed in a structure that is constrained by the coupling to the basic configuration consisting of the open sleeve (2b) and the wedge (4b) is the same as the first to second embodiments, in particular the reinforcing portion 22 of the sleeve (2b) ) Is a double structure with a stepped structure crosses at right angles and is installed and fixed at the intersection of the two rebars.

The sleeve 2b is formed with a size slightly larger than the diameter of the rebar so that one side of the cylindrical tubular body is fully opened and the rebar is fully enclosed so that the rebar is fitted to each other, and the height is the same as the diameter of the rebar. Reinforcing bars are formed so as to completely surround another rebar by extending the second reinforcing bar insertion part 22a and the second reinforcing bar insertion part 22a which are formed in the transverse direction, respectively. The second reinforcing bar insertion part 22a and the reinforcing bar insertion part 22 are formed by forming two parts slightly higher than the diameter of the two parts, respectively, and forming a locking ring 23 having the same shape as the locking ring 23 of the first embodiment. ) Centerlines intersect at right angles.

The nut 6 is attached to the sleeve 2b at the center of the bottom surface by welding or the like, and the bolt 5 is fastened or the stud bolt 5a is fastened to the nut 6 as shown in FIG. 19. The socket 6a having a female thread is connected to the stud bolt 5a, and then the hole of the socket 6a is plugged with a stopper 6b so that mortar or impurities are introduced into the socket 6a and hardened so that the bolt is not fastened. Prevent it from failing. In this way, attaching the bolts 5 to the bottom surface of the sleeve 2b is to secure the thickness of the concrete by installing a formwork horizontally and a certain distance from the bottom of the horizontal reinforcing bar installed at the bottom of the concrete construction. In addition, the installation of the stud bolts 5a and the socket 6a in the nut 6 attached to the bottom of the sleeve 2b can be carried out by removing the formwork after the formwork is removed. 6a) makes it easy to install air-conditioning ducts, sprinklers, ceiling plates, lighting, piping, etc., which eliminates the need for difficult construction to secure a separate anchor bolt later on the ceiling. In addition, the bolt part and the socket part may be integrally processed and used without the stud bolt 5a and the socket 6a installed on the nut 6 attached to the bottom surface of the sleeve 2b. ) And the length of the socket (6a) according to the specifications are used. However, there are separate spacers for reinforcing the reinforcing bars when reinforcing transverse reinforcement in the formwork, but this is merely a high role, while the reinforcing connector using the sleeves 2b and wedges 4b is in addition to restraining the reinforcing bars integrally. It can be used for multiple purposes.

The wedge 4b has the same shape as that of the second embodiment, and both ends of the transverse direction are bent in one direction so that the catch ring 45 is drawn into the two catch rings 23 of the sleeve 2. It is formed in two parts in width, and forms a through hole 47 in the center portion thereof, and then attaches the nut 6 to the stud bolts 5a by welding or the like, and fastens the stud bolts 5a to the stud bolts 5a. In order to join the upper bars in an orthogonal manner, another sleeve 2b having a nut 6 bonded to the bottom is joined and the bars are orthogonally inserted and then fixed with a wedge 4b to form a multilayer structure as shown in FIGS. 19 to 20. To achieve. Of course, this can be applied not only to the horizontal bar on the horizontal floor but also to the vertical bar on the wall or column.

As described above, as the reinforcing bar connector consisting of the sleeve 2b and the wedge 4b is coupled to the bars that meet at right angles, the coupling force is much stronger than that of the conventional binding line. In addition, even if the reinforcement in a multi-layered structure, the reinforcement itself is stronger than the simple stiff material like the conventional spacer, there is no flow in the reinforcement can be placed concrete while maintaining the position of the reinforcement. And by fixing a certain distance from the floor and maintaining the rebar spacing simultaneously solves the concrete cover thickness and rebar width fixing, and eliminates the need for wide anchorage, simplifying construction, reducing construction costs, and significantly increased strength than the ties.

Referring to the operation of the third embodiment of the present invention configured as described above by the coupling sequence as follows.

Position the sleeve 2b off the bottom of the formwork, insert one rebar 1 into the second rebar insert 22a of the sleeve 2b, and insert the other rebar 1a into the rebar insert 22 The two rebars 1 and 1a are installed at right angles, and then the wedge 4b is inserted into the sleeve 2b so that the inclined surface 23a of the sleeve 2b and the inclined surface 45a of the wedge 4b When the upper reinforcing bar 1 is pushed by sliding and contacting each other, the lower reinforcing bar 1a is also pushed at the same time, so that the cross section forms a skeleton to strengthen the reinforcement structure, there is no flow during concrete pouring, and simply stabbing A separate material such as a spacer is unnecessary.

21 to 24 show a fourth embodiment of the present invention, in which the reinforcing bar is connected to only the open sleeve 2c and the wedge 4c, as in the first embodiment, and one bar is connected to the sleeve 2c. Axially parallel to the bottom surface of the two sleeves 2c so that the two bars can be connected by restraining them with the wedge 4c and restraining the other bar with another sleeve 2c and the wedge 4c. It is characterized in that it is a structure that connects two bars in parallel by forming integrally.

The sleeve 2c has a cylindrical shape in which one surface is entirely open in the axial direction and the interior thereof is exposed, and a transverse cross section having an inner diameter corresponding to the outer diameter of the bar 12 of the reinforcing bar is fitted into the inner surface so that one reinforcing bar can be fitted. Phosphorus reinforcement insertion part 22 is formed, and both ends of the transverse direction of the reinforcement part insertion part 22 are bent in the form of a fishing needle, and a hook having an inclined surface 23a in which its bottom is inclined at an angle in the axial direction. (23) is formed in two parts to engage with each other and the engaging ring 45 of the wedge (4c) to be described later.

The sleeve 2c has a connecting portion 22b having a central portion protruding flat from the bottom surface thereof, and the other sleeve 2c formed in the same manner is coupled with the rivet 7 to parallel the two sleeves 2c.
