Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a manual clamping device for a Torque Shaper Coupler,

The present invention relates to a fastening device for a coupler, and more particularly, to a fastening device for a coupler which can easily be carried by a single worker in a complex and dangerous construction site and can be visually confirmed by fastening a deformed reinforcing bar and a coupler by using a force, To a manual fastening device for a coupler.

Generally, reinforcing bars are widely used to reinforce the strength of concrete structures embedded in concrete when reinforcing concrete structures in construction or civil engineering are applied. Especially, reinforcing bars are used for reinforcing concrete structures such as large structures, special structures, A large amount of rebar is used.

However, since these reinforcing bars are produced in a standardized size, they must be used in connection with large structures, special structures, and civil structures such as bridges.

In recent years, reinforcing bars have been used in the form of a cylindrical tube to connect both reinforcing bars at the connecting portion of the reinforcing bars, and reinforcing bars and mechanical screws The coupler that makes the connection was used.

The conventional method of connecting a plurality of reinforcing bars using a coupler has a structure in which both reinforcing bars are connected to each other by using a coupler screwed to the deformed reinforcing bars.

Therefore, a male thread portion is formed on the outer surfaces of both connection ends of the two deformed bars, and the two bars are integrally connected by a coupler by rotating the reinforcing bars and the coupler in opposite directions so that both connection ends of the deformed bar are in contact with each other.

At this time, in order to firmly connect the two deformed reinforcing bars to each other using a coupler which is threadedly connected, the coupler is mounted on both sides of the connecting ends of the one deformed reinforcing bars and the connecting ends of the other deformed reinforcing bars, It should be strongly tightened together with deformed reinforcing bars.

However, in the case of the coupler according to the related art, it is impossible to know whether the reinforcing bars and the coupler can be completely connected to each other until the reinforcing bars and the couplers are connected together for a long time. That is, the degree of tightening of the coupler to the reinforcing bars can be quantitatively controlled I could not do it, so I had to rely on my worker's ability and integrity.

That is, since the fastening degree of the coupler can not be determined according to the operator's will and skill, the quality control is not easy because the coupler can not be tightened even if the fastening of the coupler to the reinforcing bar is insufficient.

In order to solve such a problem, it is possible to visually confirm that the tightening of the coupler is made to a sufficient degree so as to prevent the situation where the coupler is insufficiently tightened by the operator, A TS coupler (Torque Shear Coulter) is introduced to make it easy to proceed.

The TS coupler according to the related art is composed of a tube-shaped member having a hollow having an inner diameter corresponding to the outer diameter of the deformed reinforcing bar at the center thereof. The outer surface of the TS coupler is formed into a hexagonal section, Are inserted and connected.

In the case of such a TS coupler, since the cross-sectional reduction portion having a reduced cross-sectional area is formed so as to have a smaller torque torque strength than the separation portion and the fastening body portion that are not reduced in cross section, the TS coupler is fastened to the separation portion in the longitudinal direction by the cross- Body part.

In such a TS coupler, a reinforcing bar is screwed to the threaded portion of the fastening body, another reinforcing bar is inserted into the hollow of the separated portion where no threaded portion is formed, and the fastening body is connected to the threaded portion of the fastening body through the separating portion, , A tool (spanner or wrench) is inserted into the separation part, and the reinforcing bars are connected to the TS coupler by rotating them in opposite directions.

At this time, when torque is applied to the fastening body portion and the separating portion in a state where the fastening body portion is positioned over the connection end portion of the double-sided reinforcing bars, when the cross-sectional reduction portion reaches a constant torque, shear fracture occurs, So that the magnitude of the torque introduced into the fastening body can be visually confirmed.

In other words, if the separating portion of the coupler is separated from the fastening body portion at the front end thereof and separated, the operator can visually confirm that the reinforcing bar has introduced a predetermined torque into the coupler.

However, since the conventional TS coupler has to rotate the reinforcing bars using a tool such as a pie french for each reinforcing bar, there is a limit to the problem that a worker rotates a plurality of reinforcing bars.

In other words, there is a limitation in that the worker puts the wrench on the coupler every time the reinforcing bar is used, and the work of tightening and rotating the wrench is repeated, thereby increasing the workload greatly, thereby deteriorating the work productivity.

An automatic coupler connecting apparatus developed to overcome the above limitations has been disclosed. The automatic coupler connecting apparatus will be described based on an example in which a connecting member is a coupler and a connecting member is a lower reinforcing bar and an upper reinforcing bar.

Such an automatic coupler connection device includes a fixed wrench portion that is fitted to a separating portion of a coupler and is mounted; And a turning wrench portion that is fitted in the lower and upper reinforcing bars and is connected to the rod end portion of the hydraulic cylinder by a turning joint portion to convert the reciprocating motion of the hydraulic cylinder into torque, And the upper reinforcing bars are automatically connected by the coupler.

The connecting end portion of the fixed wrench portion is connected to the reaction force supporting portion by a fixed joint portion, the reaction force supporting portion is connected to the body portion, a hydraulic cylinder for supplying torque is accommodated in the body portion, Shaped guide groove is formed.

The coupler for mounting the lower and upper reinforcing bars by the automatic coupler connecting device is provided with a separating portion for inserting the lower and upper reinforcing bars on one side in a state where no thread connecting portion is formed on the inner side

And a connecting body part connected to the screw connecting part formed on the inner side of the connecting screw part of the lower and upper reinforcing bars inserted through the separating part so that the lower and upper reinforcing bars are inserted and connected to the other side, Thereby forming a section reducing portion.

Therefore, when the tightening operation of the lower and upper reinforcing bars is completed, the separating portion is shearly broken from the fastening body through the section reducing portion, thereby indicating that the tightening operation of the lower and upper reinforcing bars has been completed successfully and can be visually confirmed.

However, in the process of applying torque to the fixed wrench portion fitted and attached to the separating portion of the coupler, the separating portion is excessively deformed and is not separated, or even if the separating portion is successfully separated, the separating portion is caught by the fixed wrench portion, A phenomenon in which the separating portion can not be separated occurs or an unreasonable torque is applied to the fixed wrench portion, the fixed wrench portion may be broken.

In addition, the automatic coupler connection device has a complicated structure due to the use of a separate power source, and has a problem that it is difficult to handle and move due to an increase in volume due to a power generating device and various connecting devices.

Accordingly, there is a demand for an improved coupler fastening device which does not require any additional power, has a small volume and is easy to handle by light weight, and improves workability by simple installation and operation.

[

First, the deformed reinforcing bar 200 will be briefly described. At the construction site of a nuclear reactor, a construction site, a civil engineering site, and a road, a deformed reinforcing bar is used to function as a frame before a concrete is laid. The ends of the cold-rolled screws are mechanically connected to each other by using a coupler.

That is, in order to fasten the deformed reinforcing bar 200 using a coupler, a male or female end is formed at both ends, and a coupler is positioned between both ends of the male and female ends.

In the present invention, the deformed reinforcing bar 200 is described as an upper deformed reinforcing bar 201 and the lower deformed reinforcing bar 202 as a lower deformed reinforcing bar 202, A female thread is formed on the inner surface and a body end 11 which is fastened to the lower deformed reinforcing steel 202 and a torque end 13 fastened to the upper deformed reinforcing steel 201 are connected to the fractured portion 12.

The rupturable portion 12 is formed in such a manner that when the body end 11 is fixed and the body end 11 is rotated by the torque of the torque end 13 and the torque of the torque end 13, The present invention is characterized in that the deformed reinforcing bar 200 is formed of a small diameter and a thin thickness designed according to the design of the body stage 11 and the torque stage 13 so as to be broken and cut off due to stress breakage when the allowable stress is exceeded. And the torque share coupler 10 by hand.

The reaction force member 20 is connected to the body end 11 of the torque share coupler 10 to be engaged with the torque end 13 connected to the separated breaking portion 12 when the set fastening force is exceeded .

The reaction force member 20 is formed such that the side surface of the upper deformed reinforcing bar 201 to which the torque sharing coupler 10 is fastened is inserted into the insertion space 21 and the center space 22 is seated on the upper surface of the torque end 13 .

A reaction force space 23 is formed in a lower portion of the inner space of the center space 22 so as to engage with the support portion 14 of the torque end 13 to prevent free rotation and to transmit a repulsive force. The reaction force space 23 of the torque stage 13 is supported by the support portion 14 formed in any one of a quadrangle, hexagon, octagon, twelve, gear, 23a may be formed along the inner surface.

The first gear 24a of the reaction force gear 24 is formed on the other circumferential surface except for the insertion space 21 into which the upper deformed reinforcing bar 201 is inserted.

That is, the reaction force space 23 is configured such that a corresponding support portion 23a protrudes toward the center of the reaction force space 23 and engages with the support portion 14 of the torque end 13. The shape of the corresponding support portion 23a is the same as that of the support portion 14 A hexagonal shape, a hexagonal shape, an octagonal shape, a twelve shape, a gear shape, and a sawtooth shape. However, in the present invention, the torque end 13 is formed in a hexagonal shape And each of the hexagonal faces constitutes the support portion 14. The corresponding support portion 23a is formed by four to five for example so that when the reaction force member 20 is engaged with the torque end 13, And the support portion 14 are not rotated in surface contact.

In addition, the size of the insertion space 21 may be varied depending on the diameter of the deformed reinforcing bar 200. The center space 22 is formed by the deformed reinforcing bars 200 introduced into the insertion space 21, And the top end of the torque end 13 is formed with a top end 22a which is larger than the diameter of the deformed reinforcing bar 200 and smaller than the diameter of the torque share coupler 10.

The first gear 24a of the reaction force gear 24 is formed on the other circumferential surface except for the insertion space 21 into which the upper deformed reinforcing bar 201 is inserted.

That is, the insertion space 21 and the center space 22 are formed on the same line, and the insertion space 21 and the reaction force space 23 are orthogonal to each other and are formed on the same line as the center space 22. [

The movable member 30 is coupled to move along the reaction member 20 and when the upper deformed reinforcing bar 201 is rotated while being clamped, a repulsive force is transmitted to the torque stage 13 through the reaction force member 20 So that the rupture portion 12 of the fixed body 11 is broken.

The movable member 30 is connected to the lower end of the rotary shaft 32 installed at the longitudinal center of the movable body 31 by being engaged / Thereby forming the gear 33.

Here, a pair of bearings are inserted and fastened to the inside of the movable body 31 for smooth rotation of the rotating shaft 32.

At this time, the rotary shaft 32 protrudes to the upper portion of the movable body 31, and is configured in a hexagonal shape to transmit the rotational force of the tightening handle 40 in the present invention.

The first and second clamps 34 and 35 are disposed orthogonally to one side of the upper portion of the movable body 31 to clamp the upper deformed reinforcing bar 201 in a three-point manner. The clamping portion 37 is constituted by the movable clamp 36 which performs the tightening and loosening functions.

The first and second clamps 34 and 35 are fixed to the movable body 31 and are disposed in a diaphragm arrangement with the movable clamp 36. The first and second clamps 34 and 35, The first and second protrusions 34a and 35a and the movable protrusions 36e are formed on the inner surface of the movable clamp 36 so as not to cause sliding when the movable member 30 clamps the upper deformed reinforcing bars 201, .

A support plate 38 is provided on the upper and lower surfaces of the movable gear 33 so that the support gear 38 is supported on the upper and lower surfaces of the reaction force member 20 when the movable gear 33 is gear- .

More specifically, the movable clamp 36 is disposed on one side of the upper portion of the movable body 31. The movable clamp 31 is provided on the movable shaft 31, One of the two engagement pins for fixing the bracket 36f and the movable body 31 in the state that the bracket 36f is raised to the upper portion of the movable clamp 36 is used as the movable shaft 36a.

The clamp handle 36c, which is screwed back and forth to the movable guide shaft 36b provided at the front side where the movable shaft 36a is located, is pushed by the movable clamp 36 to rotate the other end of the movable clamp 36, (201) is inclinedly clamped and the clamping force is lost by the unclamping rotation.

At this time, the clamp handle 36c is hooked to an arm spiral passing through a movable guide shaft 36b provided between the movable body 31 and the bracket 36f, for example, as a memory, and the movable guide shaft 36b And a snap ring 36c 'for preventing disengagement is connected to the end of the screw hole 36c.

The movable guide shaft 36b has a guide protrusion 36b 'inserted into the guide groove 36f' of the bracket 36f so as to prevent the forward / backward direction of the movable guide shaft 36b from being changed due to the screw engagement when the clamp handle 36c is rotated. .

The movable clamp 31 is connected to the rear side of the movable clamp 36 by the elastic member 36d so that the movable clamp 36 is elastically restored to the elastic force of the elastic member 36d during the release rotation operation of the clamp handle 36c, So as to quickly return to the non-clamping position.

In other words, the normally resilient member 36d is a tensile spring having a ring formed at both ends thereof. One end of the elastic member 36d is fastened to the rear surface of the movable clamp 36 along the longitudinal direction thereof, Which is coupled to one side of the upper surface of the housing.

The mobile strap 31 can be configured to be easily portable by providing a mobile strap 31a. The mobile strap 31a can be installed / disassembled and can be selectively used as needed. .

The fastening handle 40 for rotating the movable member 30 is formed on the rear side of the fastening hole 41 to be fastened to the upper portion of the rotary shaft 32, And a long handle bar 43 connected to the fastening hole 41 and capable of being gripped.

That is, the stopper 42 engages the fastener 41 in the direction of rotation for the operation of the movable member 30 to rotate the rotation axis 32, and the stopper 42 is rotated The fastening tool 41 and the fastening tool are rotated so that the fastening tool 41 rotates freely.

At this time, the fastening hole 41 of the fastening handle 40 is formed in a hexagonal shape so as to be coupled with the rotary shaft 32 so as to transmit the rotary movement force and may be changed according to the shape of the rotary shaft 32, It is also possible to combine an extension handle such as a separate pipe with the pin 43 to improve the fastening force with a smaller attraction force.

The manual fastening device 100 is configured such that no power is required, and portability and handling are improved.

Although the reaction gears 20 and the movable gears 33 of the movable member 30 are separated from each other in the present invention by a circular arc through-hole formed along the circumference of the reaction force member 20, The bolt passing through the through hole may be connected to the movable gear 33 to connect the reaction member 20 and the movable gear 33.

The major feature of the reaction force member 20 and the movable gear 33 in the present invention is that the diameter of the reaction force member 20 is formed larger than the diameter of the movable gear 33 so that the ratio is about 2: A large rotational force and a counter-reaction force are generated even with a small force when the movable member 30 is operated.

That is, in the present invention, the gear ratio of the reaction force member 20 and the movable gear 33 is set at a ratio of about 2: 1 based on the results of various design and fabrication tests during the manufacturing process, (20) can generate a large torque force by exerting a smooth actuation force of the movable member (30) even if the gear ratio of the gear member (33) is operated with a smaller force than when the gear ratio is 1: 1 or 1: 2 .

The operation and effect of the present invention constructed as described above will be described below.

1 to 10, in order to use the manual fastening device 100, the torque stage 13 of the torque share coupler 10 is connected to the tip of the male thread of the lower deformed reinforcing bar 202 of the deformed reinforcing bar 200, The torque sharing coupler 10 fastens the number of the upper deformed reinforcing bars 201 to the torque end 13 side and the tip end of the upper deformed reinforcing rods 201 to the torque share coupler 10.

The upper deformed reinforcing bar 201 is inserted into the reaction space 23 while the upper deformed reinforcing bar 201 is positioned at the center of the central space 22 while inserting one side of the upper deformed reinforcing bar 201 through the insertion space 21 of the reaction force member 20, Is provided so that the corresponding support surface (22a) of the torque end (13) engages with the support portion (14).

Next, the movable gear 33 of the movable member 30 is gear-engaged with the first gear 24a of the reaction force gear 24 forming the reaction force member 20, and the first and second clamps 34 35) and the movable clamp (36).

At this time, even if the movable gear 33 is disengaged from the first gear 24a of the reaction force gear 24, the support plate 38 is supported on the upper / lower surface of the reaction force gear 24, 30 are retained in a state of being engaged with gears without releasing, thereby securing the convenience of installation and stability.

Next, when the clamp handle 36c is rotated, the movable clamp 36 rotates with respect to the movable shaft 36a, and the upper deformed reinforcing bar 201 is tightly fixed together with the first and second clamps 34 and 35 So that the rotational torque force is transmitted to the reaction force member 20 through the upper deformed steel rod 201 even if a strong rotational force is applied.

When the operator holds the handle bar 43 and rotates in the clockwise direction of rotation in the clockwise direction after the fastening member 41 of the fastening handle 40 is inserted into the rotary shaft 32 of the movable member 30, The first and second clamps 34 and 35 and the movable clamp 36 are sequentially arranged in the order of the bar 43, the fastening hole 41, the rotary shaft 32, the movable gear 33, The rotational movement force of the gear 33 is transmitted to the reaction member 20 to be transmitted to the torque end 13 and the breaking end 12 to be influenced by the first and second clamps 34 and 35, The clamp 36 rotates with the upper deformed bar 201 clamped.

That is, when the movable member 30 is rotated along the reaction force member 20 using the clamping handle 40, the clamping of the first and second clamps 34 and 35 and the movable clamp 36 causes the upper The deformed reinforcing bars 201 are continuously rotated and come into contact with the ends of the lower deformed reinforcing bars 202 by screw tightening with the torque share coupler 10.

When the ends of the upper deformed reinforcing bars 201 and the lower deformed reinforcing bars 202 come into contact with each other, the rotational movement force of the movable member 30 is transmitted to the reaction force member 20. At this time, So that the reaction force member 20 is not rotated by the rotational force in the clockwise direction of rotation, and the support receives the support repulsive force.

The unrotated support repulsion force of the reaction member 20 due to the rotation of the movable member 30 is transmitted to the torque end 13 so that when the torsion stress is concentrated on the fracture portion 12, The portion 12 is shear-sheared.

The upper and lower deformed reinforcing bars 201 and 202 can be fixed to the movable member 30 and the reaction force member 20 without rotating the torque share coupler 10 due to the torsion cutting phenomenon of the breaking portion 12. [ And the torque sharing coupler 10 can be visually inspected to confirm that they are tightened with a safe safety value.

In other words, if the thickness of the rupture part 12 is large, the tightening force of the torque sharing coupler 10 should be increased. If the thickness is thin, the tightening force of the torque sharing coupler 10 is small. Thickness can be set according to the design.

Thus, the manual fastening device 100 does not require a power device such as a hydraulic device for fastening the torque-sharing coupler 10, and is characterized in that the handleability is improved using a worker having a small volume and light weight.

Further, since the reaction force member 20 can be fastened to the upper deformed reinforcing bar 201 and the torque share coupler 10 in any direction, there is no restriction on the directionality, and it is possible to easily install and operate through fitting, The time is short and the workforce is used but the worker is not fatigued because an excessive workforce is not required by using the fastening handle 40. [

In addition, when the reaction force member 20 and the movable member 30 are coupled by the gear connection and the rotational direction for rotating the movable member 30 can be arbitrarily selected, the movement amount can be adjusted according to the clamping position .

Further, there is a feature in that the user does not need to perform an action for separate gripping when moving the work site using the carrying strap 31a, and is not restricted by the behavior of the worker.
