Description

The present invention relates to a binding clip and rebar unit, in particular, it relates to a reinforcing bar unit comprising the reinforcing bars are bound by bundling clips and tie clips used in unity of two rebar.

  The foundation of a building is made by bundling a plurality of reinforcing bars such as a base muscle, a base auxiliary muscle, a main muscle, a rib muscle, an abdominal muscle, and a joint muscle, and pouring concrete from there. As a method of binding reinforcing bars, there is a conventional method of binding reinforcing bars by binding a binding wire such as an annealed iron wire using a hacker.

  However, when the reinforcing bars are bound by the binding wire, the binding wire becomes brittle due to rusting, and the binding wire may be cut off. In addition, it is necessary to knead the binding lines by hackers, and when the worker is not an expert, it takes time to bind and the work efficiency is low. Further, during the binding work, the binding wire may get caught on clothes and be damaged, or the hand may be injured. For this reason, the worker was forced to work carefully, and the work efficiency was low.

  In addition, in view of reducing the binding work between reinforcing bars at the building site and efficiently forming the foundation, before bringing the reinforcing bar into the building site, the intersection of the main and staggered muscles, the staggered muscles and the abdominal muscles in advance. There is a method of spot welding with a multi-spot welder. In this method, the stirrup and abdominal muscles are welded to form a reinforcing bar unit, the reinforcing bar unit is transported to the construction site, and the reinforcing bar unit is bound to the base bar.

  Patent Document 1 discloses a method for binding crossed reinforcing bars by using a driving machine to drive a resin clip into a crossing reinforcing bar without using a binding wire or performing welding. ing. This clip is composed of an abutment plate and two claws extending from the both ends of the abutment plate to one side. As a method for binding the clips, one reinforcing bar is accommodated in a space between two claws and in contact with the plate, and the other reinforcing bar is sandwiched between the two claws to bind the two reinforcing bars. is there.

  There is a case where a double reinforcing bar unit in which a pair of main bars is provided on each of an upper part and a lower part is used for a foundation of a wall requiring strength in a building. In the manufacturing method of the double bar arrangement unit, first, the main muscle, the stirrup muscle and the abdominal muscle are arranged in a plane in a superimposed manner at predetermined positions. Next, the main muscle, the stirrup muscle, and the stirrup and abdominal muscles are welded and joined by a multi-spot welder. Next, a bending process is performed by a bender so that four locations of each stirrup which is a portion intersecting with the main reinforcement in the double bar arrangement unit are at right angles to form a rectangular frame shape. Next, the double bar arrangement unit is completed by flaring the ends of the ribs.

  In the case of the method of forming a double bar arrangement unit by bending the stirrup after spot welding in this way, when forming a rectangular frame shape at the joint affected by the welding of the stirrup and the main reinforcement. Bending stress is applied. In such a case, the joint may be cracked due to plastic deformation due to the bending stress. As described above, the double bar arrangement unit having a crack in the joint portion does not satisfy a certain quality standard, and may be excluded before shipment as a defective product, resulting in low production efficiency.

  The joint portion is oxidized and rusted by touching the outside air, and is easily brittle. For this reason, it is not preferable to store the double bar arrangement unit including the joint portion for a long time, and it cannot be prepared for the time when production is concentrated, and the production efficiency is low.

  In addition, when the stirrup and main bars are bound by the resin clip disclosed in Patent Document 1 instead of the method of joining by welding, they may come off when the stirrup is bent by a bender. Specifically, when the main clip is accommodated in the space between the two tabs of the resin clip and in contact with the plate, and the resin clip is attached so that the ribs are pinched by the tab of the resin clip, the tab of the resin clip In some cases, the resin clip may come off due to the deformed ribs coming into contact with the edges. For this reason, it could not be used to bind two reinforcing bars in which one reinforcing bar is bent.

  This invention is made | formed in view of this subject, and it aims at improving the production efficiency of a reinforcement unit first, and it aims at improving the quality of a reinforcement unit secondly.

The above-described problem is a binding clip in which the binding clip according to the first aspect of the present invention is made of an elastic synthetic resin and binds two reinforcing bars by being pushed in, and is opened in an arc shape in one section. A main body part that extends in a direction perpendicular to the one cross section and accommodates a part of one reinforcing bar in a space inside the groove, and a space that is continuous with the groove of the main body part. A pair of extending portions extending in one direction from the main body portion, and the pair of extending portions are formed in an arc shape in another cross section perpendicular to the one cross section of the main body portion. Each of which has a recess formed in the opposite direction of the one direction from the end portion on the one direction side and opened to the one direction side, and the width of the opening portion of the recess is the other reinforcing bar The sides of the pair of extending portions facing each other are formed shorter than the diameter of the pair. The edge of the dent is formed along the outer periphery of the other reinforcing bar, and the edge surface on the main body side in the dent of the pair of extending portions is formed to be inclined with respect to each other in the one cross section. And at least one of the main body portion and the extending portion includes a protruding portion protruding from an outer surface of the main body portion or an outer surface of the extending portion, and the protruding portion is on an end side of the extending portion. This is solved by extending linearly from the direction toward the other direction .

By being configured in this manner, even if the binding clip is attached by binding two reinforcing bars, and the other reinforcing bar is bent (bending), the main body in the extension part of the binding clip The edge surface on the part side does not interfere. Therefore, even in the case of a reinforcing bar unit that requires bending at the binding site of the other reinforcing bar, such as a double reinforcing bar unit, the inner edge surface of the binding clip and the other reinforcing bar abut at the time of bending. There is nothing. For this reason, since the pulling-out by the contact of the reinforcing bar of the binding clip can be prevented, the binding clip can be used for binding a double reinforcing bar unit or the like. Moreover, according to the binding clip made of synthetic resin, the weather resistance is high and the quality is good because cracks due to rust do not occur. Furthermore, according to the binding clip made of a synthetic resin, the deterioration degree of the binding portion is remarkably low even when stored for a long time compared to the binding portion by welding, and the reinforcing bar unit can be made while avoiding the busy period. Therefore, production efficiency is high. Furthermore, since it can be easily bound using elastic deformation, the production efficiency is high. Furthermore, at least one of the main body part and the extending part includes a protruding part that protrudes from the outer surface of the main body part or the outer surface of the extending part, so that the protruding part is pushed into the protruding direction by a jig or the like. It becomes easier to apply force, and it becomes easier to fit the binding clip into the two reinforcing bars.

Further, it is preferable that the edge surface on the main body side in the recess of the pair of extending portions is formed so that an angle formed on the main body side is inclined to less than 90 degrees in the one cross section. . If it does in this way, when the other rebar will be bent within 90 degrees , the edge surface by the side of the main part in the extension part of a binding clip will not interfere.

Further, the protruding portion, the are a pair formed along the edge of the recess of the extending portion, a pair of the protrusion is preferable that extend parallel to each other. If it does in this way, when making it fit with the other rebar, the part which deforms in the extension part is formed thicker than other parts, and the probability of the breakage can be reduced.

  The synthetic resin is preferably an ABS resin. If a material having high impact resistance and appropriate elasticity such as ABS resin is employed, the binding clip can be easily attached to the two reinforcing bars.

  Further, a reinforcing bar unit according to a second aspect of the present invention includes at least one or more of the binding clip, the one reinforcing bar, and the other reinforcing bar, and at least one of the one reinforcing bar and at least one. The bent portion of the other reinforcing bar is bound and assembled by the binding clip.

  As described above, the reinforcing bar unit has high weather resistance and the quality of the reinforcing bar unit is excellent because the reinforcing bars as the constituent members are bound by the binding lip that does not cause rust cracks.

According to tying clip according to the present invention, it is possible to improve the production efficiency of the reinforcing bar unit. Furthermore, according to the reinforcing bar unit according to the present invention, the quality can be improved.

The protrusion 33 serves as a guide in the bending direction of the ribs 12 and also increases the rigidity of the claw 31 that is elastically deformed by increasing the thickness of the claw 31.

  Here, the pull-in bender 5 used for manufacturing the double bar arrangement unit 10 will be described. As shown in FIG. 8, the pull-in vendor 5 includes a mounting table 50, a pull-in hook 51, a rotation roller 52, and a spacer 53.

  The mounting table 50 has a substantially horizontal mounting surface 50a, and has a groove 50b having a predetermined width and a predetermined length. The pull-in hook 51 has a protruding portion 51a, is formed in an inverted J shape having a predetermined width and thickness, and is disposed so as to protrude from the groove 50b. The pull-in hook 51 is arranged to be movable in the vertical direction by a control unit and a drive unit (not shown).

  Further, a pair of rotating rollers 52 are disposed in the horizontal direction along both edges of the groove 50b in the vicinity of the lower side of the placement surface 50a. The rotating roller 52 is supported by the mounting table 50 so as to be rotatable about a horizontal axis, and rotates according to a rotational torque applied to the peripheral surface.

  The spacer 53 is made of a metal rigid material, and is a jig that holds the pair of main bars 11 and keeps the interval constant.

  Next, the manufacturing method of the double bar arrangement unit 10 is demonstrated. First, a manufacturing method using the pull-in vendor 5 will be described.

  First, a pair of abdominal muscles 13 are placed at predetermined positions on the plurality of ribs 12 in a direction perpendicular to the plurality of ribs 12. Next, a cross spot-abdominal muscle unit 10a is formed by spot-welding the intersection of a pair of abdominal muscles 13 and a plurality of rib muscles with a multi-spot welder. Next, a plurality of glasses clips 2 are attached to each of the two pairs of main muscles 11 and held at predetermined intervals. Next, as shown in FIG. 6, the main muscle 11 to which the eyeglass-shaped clip 2 is attached on the unit in which the plurality of ribs 12 and the pair of abdominal muscles 13 are joined is in a direction perpendicular to the ribs 12. Place it in place.

  Next, as shown in FIG. 7, the pushing portion 40 of the pushing jig 4 is brought into contact with the protruding portion 33 of the binding clip 3, and the pushing jig 4 is driven by a hammer or the like (not shown) so that the binding clip 3 is Push into the intersection of 11 and stirrup 12. At this time, a part of the main muscle 11 passes through the space 31 a and is accommodated in the internal space 30 b, and the ribbed muscle 12 is held between the claws 31 by expanding the depression 32. In this way, a flat planar bar arrangement unit 10b composed of the main muscle 11, the rib muscle 12, the abdominal muscle 13, the glasses clip 2 and the binding clip 3 is formed.

  Next, as shown in FIG. 8, the flat bar arrangement unit 10 b is mounted on the mounting table 50 of the pull-in bender 5. At this time, as shown to Fig.9 (a), it mounts so that any one main reinforcement | strut 11 may be arrange | positioned under the protrusion part 51a of the drawing hook 51 vertically.

  Next, as shown in FIG. 9B, the pull-in hook 51 is moved downward to a predetermined position where the stirrup 12 is bent substantially vertically. At this time, the main muscle 11 moves downward along with the movement of the pull-in hook 51 by contacting the protruding portion 51 a of the pull-in hook 51. As described above, the plural streaks 12 are bound to the main muscle 11 in the vertical direction by the binding clip 3. The plurality of stirrups 12 are supported at two places by the mounting table 50 or the pair of rotating rollers 52, and a downward force is applied along with the downward movement of the main bars 11 between the two places. Bends in an L shape. Thus, one corner of a plurality of stirrups 12 formed in a square frame shape in the double bar arrangement unit 10 is formed.

  In the process of pulling the main bar 11 by the pull-in hook 51, a force is applied from the pull-in hook 51 to one of the main bars 11 in a direction in which the pair of main bars 11 are separated from each other. Is maintained. On the other hand, the eyeglass-shaped clip 2 holds the main reinforcing bars 11 within a predetermined range. However, since the distance between the main reinforcing bars 11 is maintained by the spacer 53, the main clip 11 is not subjected to a load during this processing. In other words, the eyeglass-shaped clip 2 is not deformed and not damaged by the clearance between the main bar 11 and the groove 21a when the stirrup 12 is bent.

  Next, as shown in FIG. 9C, the pull-in hook 51 is returned to the upper position, and the flat bar arrangement unit 10 b is arranged with the other main reinforcing bar 11 vertically below the protrusion 51 a of the pull-in hook 51. To be placed.

  Next, as shown in FIG. 9D, the retracting hook 51 is moved downward to a predetermined position. At this time, the main muscle 11 moves downward along with the movement of the pull-in hook 51 by contacting the protruding portion 51 a of the pull-in hook 51. The plurality of stirrups 12 are supported at two places by the mounting table 50 or the pair of rotating rollers 52, and a downward force is applied along with the downward movement of the main bars 11 between the two places. Bends in an L shape. In this way, the other corner of the plurality of ribs 12 formed in a square frame shape in the double bar arrangement unit 10 is formed.

  Similarly, the other two main bars 11 are pulled in by the pull-in hook 51, and the plurality of ribs 12 are indirectly bent to form the other two corners. Then, both end portions 12a of the plurality of stirrups 12 are flare welded to form a square frame shape, and the double bar arrangement unit 10 is completed.

  Further, the double bar arrangement unit 10 may be manufactured by using the push-up bender 6 described below instead of the pull-in bender 5.

  As shown in FIG. 10, the push-up bender 6 includes a mounting table 60, a jig 61 that is fixed to the mounting table 60 and arranged in a row, and a support bar that supports the plurality of jigs 61. 62 and a cylindrical pushing roller 63.

  The mounting table 60 has a substantially horizontal mounting surface 60a, and has a stage 60b that protrudes in one direction on the horizontal plane and extends in the other direction perpendicular to the one direction. The stage 60b has a groove 60c extending in the other direction.

  The jig 61 is fixed to the stage 60b by a bolt 61b and a nut 61c through a groove 60c, and includes a support portion 61a having an arc-shaped cross section and extending in the other direction. The support portions 61 a of the plurality of jigs 61 are configured so that the stirrup 12 is placed on the mounting table 60, and the support bar 62 is placed on the stirrup 12 while contacting the side surface of the jig 61. It is formed at a height that covers the upper part of 62.

  The support bar 62 is a reinforcing bar having a diameter substantially the same as that of the main reinforcing bar 11. The pushing roller 63 extends in the other direction and is arranged so as to be swingable in an arc shape in the vertical direction by a control unit and a driving unit (not shown).

  In the method of manufacturing the double bar arrangement unit 10 using the pull-in bender 5 described above, the flat bar arrangement unit 10b is formed in advance by the eyeglass-shaped clip 2 and the binding clip 3, and then the stirrup 12 is bent by the pull-in bender 5. Apply. In addition, since it is the structure which carries out the bending process to the stirrup muscle 12 indirectly via the main reinforcement 11, it is possible to draw the main reinforcement 11 by the drawing bender 5 in the position away from the binding site | part of the main reinforcement 11 and the separate reinforcement 12. It is.

  On the other hand, in the push-up bender 6, since the stirrup 12 is directly bent by the push roller 63, the push bender 6 is close to the housing portion 21 of the eyeglass-shaped clip 2 or to the binding portion of the binding clip 3. The pushing roller 63 swings to the position where it moves. For this reason, the pushing roller 63 may come into contact with the glasses clip 2 and the binding clip 3 and be detached. Therefore, in the manufacturing method of the double bar arrangement unit 10 using the push-up bender 6, the details will be described next. After the stirrup 12 is formed in a rectangular frame shape by the push-up bender 6, the binding clip 3 is used. A method of binding two pairs of main muscles 11 is adopted.

  Next, a method for manufacturing the double bar arrangement unit 10 using the push-up bender 6 will be described.

  First, the pair of abdominal muscles 13 are placed at predetermined positions on the plurality of ribs 12 so as to be perpendicular to the plurality of ribs 12. Next, each crossing site | part of the abdominal muscle 13 and the several stirrup muscles 12 is spot-welded with a multi spot welding machine.

  Next, as shown in FIGS. 10 and 11A, the stirrup muscle 12 is protruded from the support rod 62 by a predetermined amount, and the stirrup-abdominal muscle unit 10 a is placed on the placing table 60 of the push-up bender 6. To do.

  Next, as shown in FIG. 11B, the pushing roller 63 is swung upward to a predetermined position. At this time, as the push roller 63 swings, the plurality of stirrups 12 abut against the upper portion of the push roller 63 and a bending moment is applied with the support rod 62 as a fulcrum. The plurality of ribs 12 bend in an L shape upward. Thus, one corner of the plurality of stirrups 12 formed in a rectangular frame shape is formed.

  Similarly, a plurality of stirrups 12 are bent at three locations at predetermined positions into an L shape to form a total of four corners, and both end portions 12a of the plurality of stirrups 12 are subjected to flare welding. It is formed in a rectangular frame shape as shown in FIG.

  Next, as shown in FIGS. 12 (a) and 13 (b), the pair of main muscles 11 held by the glasses-shaped clip 2 are placed on one side of the rib-abdominal muscle unit 10a formed in a lattice shape. Insert the other pair of main muscles 11 into the other side of the rib-abdominal muscle unit 10a.

  Next, as shown in FIGS. 12 (b) and 13 (c), the binding clip 3 is formed at the four corners of the plurality of stirrups 12 and at the portion where the two pairs of main muscles 11 and the plurality of stirrups 12 intersect. Is attached from the main muscle 11 side to bind the main muscle 11 and the stirrup muscle. The binding clip 3 is attached by driving the pressing jig 4 with a hammer or the like (not shown) in a state where the pressing portion 40 of the pressing jig 4 is in contact with the protruding portion 33 of the binding clip 3 as described above. It is made with. Thus, the double bar arrangement unit 10 is completed.

  As mentioned above, although this invention was concretely demonstrated based on embodiment, this invention is not limited to these embodiment. Various modifications, such as combining each feature, are possible without departing from the scope of the invention.

  For example, in the above-described embodiment, a reinforcing bar unit composed of a main bar having a diameter of 16 mm and a stirrup bar having a diameter of 10 mm has been described, but the present invention is not limited to this. As described above, it can be applied to rebars of other sizes by matching the size of the storage part of the glasses-shaped clip and the size of the groove and recess of the binding clip according to the size of the main and stirrup It is.

  Furthermore, the binding clip is not limited to the binding of reinforcing bars, but also the binding of metal wires intersecting the greenhouse, and the binding of bars fixed to the back of the display board and other bars perpendicular to this bar Or you may make it apply to the binding of the clothesline and a hanger.

  In addition, in the said embodiment, although demonstrated that the shape of the cross section of the main-body part in a binding clip was circular arc shape, the binding clip which concerns on this invention is not limited to this shape. For example, since the binding clip has a function of accommodating the main muscle, the inner edge of the main body portion only needs to have an arc shape, and does not need to be arc-shaped to the outer edge. Specifically, a plane perpendicular to the pressing direction may be formed on a part of the outer edge so that the pressing is facilitated.
