However, in the above-described conventional clip for reinforcing bar crossing portion, when the vertical bar hooking part is wound around the back side of the vertical bar from one side, the elasticity of the linear portion of the L-shaped vertical bar hooking part is increased. Since the horizontal muscles are pressed against the vertical muscles and locked by only such a restoring force, it is necessary for the operator to apply a large force to the fingertip when the vertical muscle hooking portion is hung around the vertical muscles. There was a problem that the worker felt pain in the fingertip during repeated operation and the work efficiency decreased.
On the other hand, in order to allow the operator to hang it with a small force, it is necessary to lengthen the dimension of the straight part of the vertical bar suspension part. Therefore, it cannot be used in a narrow space where the arrangement of reinforcing bars is complicated, and there is a problem that working efficiency is reduced by using a binding wire together.

Therefore, the present invention is to solve the problems of the above-described conventional techniques, that is, the object of the present invention is to apply a vertical force to the vertical stripes by applying a small force to the vertical stripes. It is to provide a compact clip for a reinforcing bar crossing part capable of firmly locking the.

The above-mentioned problems are solved by being integrally configured in the arrangement order.

In addition to the structure of the clip for rebar crossing parts described in claim 1, the invention according to claim 2 is characterized in that the torsion spring part is arranged so as to face the second vertical bar embracing bar, and the horizontal bar By forming the sandwiching space, the above-mentioned problems are solved.

The invention according to claim 3 is configured by the first horizontal bar retaining bar and the first vertical bar embracing bar in addition to the configuration of the reinforcing bar crossing clip described in claim 1 or claim 2. The first locking angle is configured to be substantially right angle, and the second locking angle formed by the second horizontal bar locking bar and the second vertical bar holding bar is configured to be larger than the first locking angle. By doing so, the above-mentioned problems are further solved.

In addition to the structure of the reinforcing bar crossing clip described in any one of claims 1 to 3, the invention according to claim 4 has the second horizontal bar locking bar and the vertical bar holding The second connecting angle formed by the tangential direction of the corner is formed at a substantially right angle, and the first connecting angle formed by the first horizontal bar locking bar and the tangential direction of the vertical line holding corner is greater than the second horizontal line locking. Also, the above-mentioned problems are solved by being configured at a small angle.

In addition to the configuration of the reinforcing bar crossing clip according to any one of claims 1 to 4, the invention according to claim 5 is characterized in that the vertical bar engaging lever is the second lateral bar link. The above-mentioned problem is solved by being configured to incline to the side opposite to the torsion spring portion with respect to the stop bar.

According to the clip for reinforcing bar crossing part according to claim 1 of the present invention, in the clip for reinforcing bar crossing part made of a metal wire rod that locks these reinforcing bars at the crossing parts of the vertical bars and the horizontal bars that are orthogonal to each other, A first horizontal bar locking portion including a first horizontal bar locking bar and a quarter-arc-shaped first horizontal bar locking corner, a linear first vertical bar holding bar, a semi-circular vertical bar holding corner and a straight line Of the vertical bar holding bar of the second vertical bar, and a second horizontal bar locking section composed of a second horizontal bar locking corner having a substantially quarter arc shape and a second linear horizontal bar locking bar, and a winding A horizontal torsion bar portion, a linear vertical bar hooking lever, a semi-arcuate vertical bar hooking corner, and a vertical bar hooking part composed of a linear vertical bar hooking bar. The locking portion, the vertical streak holding portion, the second horizontal streak locking portion, the torsion spring portion, and the vertical streak hook portion are the first horizontal streak locking portion, the vertical streak holding portion, the second horizontal streak locking portion, and the torsion spring. Section and vertical bar hooking section are arranged in a single unit in the order in which they are twisted when the vertical bar hooking section is rotated in the direction in which the vertical bar hooking section uses the second horizontal bar locking corner as a fulcrum. Since the spring portion is elastically deformed and the distance between the fulcrum force points is substantially increased, it is possible to hang the vertical streak engaging portion on the vertical streak with a small force.

According to the reinforcing bar crossing portion clip of claim 2 of the present invention, the torsion spring portion is arranged so as to face the second vertical bar embracing bar to form the horizontal bar sandwiching space.

According to the clip for reinforcing bar crossing portion of the third aspect of the present invention, the first locking angle formed by the first horizontal bar locking bar and the first vertical bar holding bar is configured to be substantially right angle, and the second horizontal bar engaging bar is formed. Since the second locking angle formed by the stop bar and the second vertical bar holding bar is configured to be larger than the first locking angle, the vertical bar hooking part is hooked on the vertical bar with the horizontal bar as a fulcrum. When turned, the second locking angle becomes smaller and approaches a right angle due to elastic deformation, so that the first horizontal muscle locking portion and the second horizontal muscle locking portion have substantially the same shape when viewed from the axial direction of the horizontal muscle. It becomes possible to press the horizontal line and lock it in a well-balanced manner.

According to the clip for reinforcing bar crossing part according to claim 4 of the present invention, the second connecting angle formed by the second horizontal bar locking bar and the tangential direction of the vertical bar embracing corner is formed at a substantially right angle, and Since the first connecting angle formed by the one horizontal bar locking bar and the tangential direction of the vertical bar holding corner is configured to be smaller than the second horizontal bar locking, the vertical bar hooking section with the horizontal bar as a fulcrum. Since the first locking angle increases due to elastic deformation and approaches a right angle when it is hung on the vertical bar, the first horizontal bar locking part and the second horizontal bar locking part are attached to both the vertical bar and the horizontal bar. When viewed in a direction orthogonal to each other, the shapes are almost the same, and the lateral streaks can be pressed, and more evenly balanced locking can be achieved.

FIG. 3 is a schematic view showing a state in which a vertical bar and a horizontal bar are mutually locked using a clip for a reinforcing bar crossing portion which is an embodiment of the present invention. The schematic diagram which shows the state which mutually locked the main bar and the stirrups using the clip for rebar crossing parts which is another Example of this invention.

A clip for a reinforcing bar crossing portion of the present invention is made of a metal wire rod, and a first horizontal bar locking portion composed of a linear first horizontal bar locking bar and a quarter arc-shaped first horizontal bar locking corner, a linear first vertical line. Longitudinal streak holding section consisting of streak holding bar, semi-circular vertical stirrup holding corner and linear second vertical streak holding bar, substantially quarter arc second horizontal stirrup engaging corner and straight second Second horizontal bar locking part consisting of horizontal bar locking bar, winding torsion spring part, linear vertical bar locking lever, semi-circular vertical bar locking corner and linear vertical bar locking bar The first horizontal bar engaging part, the vertical bar retaining part, the second horizontal bar engaging part, the torsion spring part and the vertical bar engaging part are the first horizontal bar engaging part. , The vertical streak holding part, the second horizontal streak locking part, the torsion spring part, and the vertical stirrup suspension part are arranged in an integrated sequence, and the vertical stirrup suspension part can be hung around the vertical stirrup with a small force. Any specific embodiment may be used as long as it is possible.

That is, the metal wire rod which constitutes the clip for reinforcing bar intersection of the present invention may have a circular cross section, a rectangular shape or other shapes as long as it can lock the reinforcing bar by the restoring force by elastic deformation. The spiral torsion spring portion may have a shape wound into an arc shape, a rounded corner triangular shape, a rounded corner quadrangular shape, or another shape, or may be wound plural times.

Further, the shape of the first horizontal bar locking corner, the vertical bar holding corner, the second horizontal bar locking corner and the vertical bar hooking corner of the reinforcing bar crossing clip according to the present invention, that is, the diameter of the arc inside the corner is , Can be set according to the diameter of the reinforcing bar to be locked.

For example, when using a D10 reinforcing bar, it is preferable to set the arc radius of each corner to half of the outermost diameter of 11 mm, that is, about 5.5 mm. Similarly, when the reinforcing bar of D13 is used, the radius of the arc of each corner is preferably about 7 mm, and in the case of D16, D19, and D22, the radius of the arc of the corner is 9 mm, 10.5 mm, and 12. It is preferably about 5 mm.

However, it is needless to say that even if the diameter of the reinforcing bar and the diameter of each corner do not exactly correspond to each other, the reinforcing bars can be locked to each other using the reinforcing bar crossing clip of the present invention.

Further, the distance between the second vertical bar holding bar and the torsion spring part of the reinforcing bar crossing clip according to the present invention, that is, the holding width of the horizontal bar holding space corresponds to the diameter of the reinforcing bar to be locked, It is preferable to set it to be slightly smaller than this.

For example, when using a D10 reinforcing bar, it is preferable to set the holding width to about 8.5 mm. Similarly, when the reinforcing bar of D13 is used, the holding width is preferably about 11.5 mm, and in the case of D16, D19 and D22, the holding width is preferably about 15 mm, 18 mm and 21 mm, respectively.

However, in the case of locking a reinforcing bar having a diameter larger than the clamping width, pressing and inserting the reinforcing bar into the lateral clamping space causes the torsion spring part to elastically deform, and the second vertical reinforcing bar and the torsion spring. By firmly sandwiching the reinforcing bar with the part, it can be firmly locked.

Therefore, when the sandwiching width is set to, for example, about 8.5 mm, not only the reinforcing bar of D10 but also the reinforcing bar of D13 can be locked, and when the reinforcing bar of D13 is used, it is more firmly engaged. You can stop.

Hereinafter, a clip for a reinforcing bar crossing portion according to an embodiment of the present invention will be described with reference to FIGS. 1 to 3B.

As shown in FIGS. 1 to 2F, the reinforcing bar crossing clip 100 according to the present embodiment is made of an iron wire material, and has a linear first horizontal bar locking bar 111 and a quarter arc-shaped first horizontal bar locking corner 112. A horizontal stirrup retaining section 110, a straight first vertical stirrup bar 131, a semi-arcuate vertical stirrup corner 133, and a second vertical stirrup bar 132. Section 130, a second horizontal bar locking section 120 consisting of a second horizontal bar locking corner 122 and a linear second horizontal bar locking bar 121, a spiral torsion spring section 140, and a linear A vertical bar hooking lever 152, a vertical bar hooking corner 153 having a semi-arcuate shape, and a vertical bar hooking part 150 including a straight bar hooking bar 151. The muscle holding portion 130, the second horizontal muscle locking portion 120, the torsion spring portion 140, and the vertical muscle hooking portion 150 include the first horizontal muscle locking portion 110, the vertical muscle holding portion 130, the second horizontal muscle locking portion 120, The torsion spring portion 140 and the vertical stirrup portion 150 are integrally formed in the order of arrangement.

More specifically, in the reinforcing bar crossing clip according to the present embodiment, the linear first horizontal bar locking bar 111, the quarter arc-shaped first horizontal bar locking corner 112, and the linear first vertical bar holding. Bar 131, semi-arcuate vertical bar embracing corner 133, linear second vertical bar embracing bar 132, substantially quarter arc arc second horizontal bar engaging corner 122, linear second horizontal bar engaging bar 121, The spiral torsion spring portion 140, the linear vertical bar hooking lever 152, the semi-circular vertical bar hooking corner 153, and the linear vertical bar hooking bar 151 are arranged in the order of arrangement described in this paragraph. It is configured as one.

As shown in FIG. 2C and FIG. 2D, while the second connecting angle β formed by the second horizontal bar locking bar 121 and the tangential direction of the vertical bar embracing corner 133 is configured to be substantially right angle, The first connecting angle α formed by the first horizontal bar locking bar 111 and the tangential direction of the vertical bar holding corner 133 is configured to be slightly smaller than the second connecting angle β.

As shown in FIG. 2A, the second vertical holding bar 132 and the second horizontal locking bar 121 are configured so that the second locking angle δ is substantially right, while in FIG. 2B. As shown, the first locking angle γ formed by the first vertical bar embracing bar 131 and the first horizontal bar locking bar 111 is configured to be slightly smaller than the second locking angle δ. ..

As shown in FIG. 2A, the vertical bar hooking lever 152 is configured to incline to the second horizontal bar locking bar 121 on the side opposite to the torsion spring portion 140. That is, the arm angle ε formed by the vertical bar hooking lever 152 and the second horizontal bar locking bar 121 is configured to be an angle slightly smaller than two right angles.

As shown in FIGS. 2C and 2D, the vertical streak engaging angle ζ formed by the vertical stirrup lever 152 and the vertical streak bar 151 is slightly larger than 0 degree, that is, a J-shape. It is configured so that the space between the two becomes a slight opening angle.

As shown in FIG. 2A and FIG. 2B, the torsion spring portion 140 is arranged so as to face the second vertical bar embracing bar 132, and the torsion spring portion 140, the second horizontal bar locking corner 122, and the second vertical bar. The muscle holding bar 132 forms a horizontal muscle holding space RS for holding the horizontal muscle.

Next, a procedure for locking mutually orthogonal reinforcing bars by using the reinforcing bar crossing clip 100 according to the present embodiment will be described. Here, as shown in FIG. 3A, an example will be described in which the horizontal muscle TR is locked to the vertical muscle LB at a predetermined height on the front side of the vertical muscle LB.

First, the horizontal muscle TR is lifted up to a predetermined height with respect to the vertical muscle LB, and the vertical muscle holding corner 133 is applied to the vertical muscle LB from the back side of the vertical muscle LB at a position higher than the horizontal muscle TR. The locking bar 111 and the second horizontal bar locking bar 121 are lowered to a position where they come into contact with the horizontal bar TR.

Here, when the vertical muscle embracing portion 130 holds the vertical muscle LB and is positioned so that the first horizontal muscle locking bar 111 abuts the horizontal muscle TR, the second vertical muscle embracing bar 132 and the second horizontal muscle engagement bar 132. The second locking angle δ formed by the stop bar 121 is configured to be substantially a right angle, while as shown in FIG. 2B, the first vertical bar retaining bar 131 and the first horizontal bar locking bar 111. Since the first locking angle γ formed by and is configured to be slightly smaller than the second locking angle δ, the second horizontal bar locking bar 121 is arranged at a position slightly floating from the horizontal bar TR. Will be done.

The distance between the second vertical strip embracing bar 132 and the torsion spring portion 140, that is, the sandwiching width of the horizontal strip sandwiching space RS is configured to be slightly smaller than the diameter of the horizontal strip, so the horizontal strip TR is inserted into the horizontal strip sandwiching space RS. In order to do so, it is necessary to press the second horizontal bar locking bar 121 in the direction of the horizontal bar TR for fitting.

Therefore, the vertical streak latch lever 152, which is configured to incline to the side opposite to the torsion spring portion 140 with respect to the second horizontal streak locking bar 121 and is located on the front side of the vertical streak LB, moves the vertical streak lever 152. When the horizontal bar TR is pressed so as to approach the LB, the horizontal bar TR fits into the horizontal bar sandwiching space RS formed by the torsion spring portion 140, the second horizontal bar locking corner 122, and the second vertical bar embracing bar 132.

At this time, the torsion spring portion 140 is elastically deformed and comes into contact with the lateral stripe at the horizontal streak pressing contact 141, but due to the restoring force of the torsion spring section 140, the torsion spring section 140 and the second vertical bar holding bar 132. With, the lateral muscle TR is firmly clamped.

Then, as shown in FIG. 3B, if the vertical streak hooking lever 152 is further pushed to the back side of the vertical streak bar LB, and the tip of the vertical streak bar 151 is wound around the vertical streak bar LB, Since the vertical streak hook angle ζ formed by the vertical streak bar 151 with respect to the lever 152 is set to open to about 5 degrees, the vertical streak corner 153 is set by the restoring force of the torsion spring portion 140. It is possible to deform the LB to a position in which it abuts from the back side and to hang the vertical bar hooking portion 150, and the vertical bar hooking bar 151 and the vertical bar hooking lever 152 sandwich the vertical bar LB, and the horizontal bar TR. The vertical streaks LB are firmly locked.

The size of the first locking angle γ, which is formed substantially at a right angle, when the vertical bar hooking portion 150 is wound around, the second locking angle δ decreases due to elastic deformation of the second horizontal bar locking corner 122. Since the first horizontal muscle locking portion 110 and the second horizontal muscle locking portion 120 have substantially the same shape when viewed from the axial direction of the horizontal muscle TR, the horizontal muscle TR can be pressed and balanced in a balanced manner. it can.

Further, when the vertical bar hooking portion 150 is wound around, the first connecting angle α increases due to the elastic deformation of the first horizontal bar locking corner 112, and the size of the second connecting angle β is formed substantially at a right angle. , The first horizontal muscle locking portion 110 and the second horizontal muscle locking portion 120 have substantially the same shape when viewed from the direction orthogonal to both the vertical muscle LB and the horizontal muscle TR, and press the horizontal muscle TR, Further, it can be locked with a good balance.

Next, a clip for a reinforcing bar crossing portion, which is another embodiment of the present invention, will be described with reference to FIG.

FIG. 4 is a schematic diagram showing a state in which a main bar and a stirrup bar are mutually locked by using a clip for a reinforcing bar crossing portion which is another embodiment of the present invention.

As shown in FIG. 4, a method of using the reinforcing bar intersection clip 100 of the present invention will be described when the ribs RR among the intersections of the main bars MR and the stirrups RR forming the beam are bent. To do.

When the ribs RR are bent at the intersection of the main muscles MR and the ribs RR, as shown in FIG. 4, the longitudinal muscles LB and the transverse muscles TR in Example 1 are respectively changed to the ribs RR and the main muscles MR. By replacing, it can be locked as in the first embodiment.
That is, even at the intersection where one of the reinforcing bars is bent, locking can be performed using the reinforcing bar intersection clip 100 having exactly the same shape as the case where the linear reinforcing bars intersect.

As described above, according to the reinforcing bar crossing clip 100 according to these examples, the vertical bar hooking portion 150 can be easily hooked on the vertical bar LB with a small force, and the horizontal bar TR can be connected to the vertical bar LB. In contrast, it can be locked firmly and in good balance.

The present invention relates to a reinforcing bar crossing clip made of a metal wire rod that interlocks these reinforcing bars at a crossing portion of vertical bars and horizontal bars that are orthogonal to each other.

Conventionally, in reinforcing bar assembly work performed at a construction site or the like, an iron binding wire having no spring property is used to bind and lock a vertical bar and a horizontal bar, or instead of such a binding wire, a vertical bar is used.

Further, the torsion spring portion is provided opposite to the second vertical strip embracing bar with the horizontal strip pressing contact that elastically deforms when the horizontal strip is fitted into the horizontal strip sandwiching space and contacts the horizontal strip. When a horizontal bar having a diameter larger than the clamping width is fitted in the lateral bar clamping space, the torsion spring part elastically deforms and the lateral bar pressing contact comes into contact with the lateral bar, so the torsion spring part is restored by the restoring force of the torsion spring part. The horizontal bar can be strongly clamped by the second vertical bar holding bar.

Further, the vertical bar hooking lever is configured to be inclined to the side opposite to the torsion spring part with respect to the second horizontal bar locking bar, so that the vertical bar holding section holds the vertical bar, and When the first horizontal bar locking bar is positioned so as to abut the horizontal bar, the vertical bar locking lever located on the front side of the vertical bar is pressed so as to approach the vertical bar, and the second horizontal bar locking bar is Since it is pressed in the direction of the horizontal line, the horizontal line having a diameter larger than the holding width can be easily fitted into the horizontal line holding space.

According to the reinforcing bar crossing clip according to claim 2 of the present invention, since the arm angle formed by the vertical bar hooking lever and the second horizontal bar locking bar is slightly smaller than two right angles , the vertical bar If you push the hanging lever to the back of the vertical bar, the tip of the vertical bar hook bar will be hooked around the vertical bar, so the vertical bar can be hooked on the vertical bar with a small force. The horizontal stripes and the vertical stripes can be firmly locked.

According to the clip for reinforcing bar crossing portion of the third aspect of the present invention, the first locking angle formed by the first horizontal bar locking bar and the first vertical bar holding bar is configured to be substantially right angle, and the second horizontal bar engaging bar is formed. Since the second locking angle formed by the stop bar and the second vertical bar holding bar is configured to be larger than the first locking angle, the vertical bar hooking part is hung around the vertical bar with the horizontal bar as a fulcrum. In doing so, the second locking angle becomes smaller and approaches a right angle due to elastic deformation, so that the first horizontal bar locking part and the second horizontal bar locking part have almost the same shape when viewed from the axial direction of the horizontal bar. The horizontal line can be pressed to lock in a well-balanced manner.

According to the clip for reinforcing bar crossing part according to claim 4 of the present invention, the second connecting angle formed by the second horizontal bar locking bar and the tangential direction of the vertical bar embracing corner is formed at a substantially right angle, and Since the first connecting angle formed by the one horizontal bar locking bar and the tangential direction of the vertical bar holding corner is configured to be smaller than the second horizontal bar locking, the vertical bar hooking section with the horizontal bar as a fulcrum. Since the first locking angle increases due to elastic deformation and approaches a right angle when it is hung on the vertical bar, the first horizontal bar locking part and the second horizontal bar locking part are attached to both the vertical bar and the horizontal bar. When viewed in a direction orthogonal to each other, the shapes are almost the same, and the lateral streaks can be pressed, and more evenly balanced locking can be achieved.

According to the clip for reinforcing bar crossing portion of the fifth aspect of the present invention, the vertical bar hooking angle formed by the vertical bar hooking bar with respect to the vertical bar hooking lever is set to open to about 5 degrees. As a result, if the tip of the vertical streak bar is wound around the vertical stirrup, the restoring force of the torsion spring deforms the vertical stirrup corner to the position where it abuts against the vertical streak. The portion can be hung around the vertical streak to hold the vertical streak by the vertical streak bar and the vertical streak lever.

The schematic diagram which shows the state which mutually locked the main bar and the stirrups using the clip for rebar crossing parts which is another Example of this invention.

The reinforcing bar crossing portion clip of the present invention is made of a metal wire rod, and has a first horizontal bar locking portion including a linear first horizontal bar locking bar and a quarter arc-shaped first horizontal bar locking corner, and a linear first bar. A vertical bar holding bar composed of a vertical bar holding bar, a semi-arcuate vertical bar holding corner and a linear second vertical bar holding bar, and a second quarter bar locking corner and a straight line of a substantially quarter arc shape. A second horizontal bar locking part consisting of a second horizontal bar locking bar, a spiral torsion spring part, a linear vertical bar hooking lever, a semi-circular vertical bar hooking corner and a linear vertical bar hook. and a vertical line train-around portion consisting of round bars, a first horizontal strip locking portion and the longitudinal muscle holding portion and the spring portion torsion second lateral stripes locking portion and the vertical line train-around portion, the first horizontal strip engagement The stopper, the vertical bar embracing part, the second horizontal bar locking part, the torsion spring part, and the vertical bar hooking part are arranged in the order of arrangement , and the torsion spring part, the second horizontal bar locking corner, and the second vertical bar The holding bar forms a horizontal streak holding space for holding the horizontal stirrup, and the torsion spring portion is provided with a horizontal streak pressing contact that elastically deforms and comes into contact with the horizontal streak when the horizontal streak is fitted into the horizontal streak holding space. It is arranged so as to face the two vertical bar embracing bars, and the vertical bar hooking lever is configured to incline to the side opposite to the torsion spring portion with respect to the second horizontal bar locking bar, so that the horizontal bar is within the horizontal bar clamping space. As long as it can be easily fitted and locked to, and is strongly clamped, and the vertical bar engaging portion can be hooked on the vertical bar with a small force, its specific embodiment is any It doesn't matter.

That is, the metal wire rod which constitutes the clip for reinforcing bar intersection of the present invention may have a circular cross section, a rectangular shape or other shapes as long as it can lock the reinforcing bar by the restoring force by elastic deformation. The spiral torsion spring portion may have a shape wound into an arc shape, a rounded corner triangular shape, a rounded corner quadrangular shape, or another shape, or may be wound plural times.

Further, the shape of the first horizontal bar locking corner, the vertical bar holding corner, the second horizontal bar locking corner and the vertical bar hooking corner of the reinforcing bar crossing clip according to the present invention, that is, the diameter of the arc inside the corner is , Can be set according to the diameter of the reinforcing bar to be locked.

For example, when using a D10 reinforcing bar, it is preferable to set the arc radius of each corner to half of the outermost diameter of 11 mm, that is, about 5.5 mm. Similarly, when the reinforcing bar of D13 is used, the radius of the arc of each corner is preferably about 7 mm, and in the case of D16, D19, and D22, the radius of the arc of the corner is 9 mm, 10.5 mm, and 12. It is preferably about 5 mm.

However, it is needless to say that even if the diameter of the reinforcing bar and the diameter of each corner do not exactly correspond to each other, the reinforcing bars can be locked to each other using the reinforcing bar crossing clip of the present invention.

Further, the distance between the second vertical bar holding bar and the torsion spring part of the reinforcing bar crossing clip according to the present invention, that is, the holding width of the horizontal bar holding space corresponds to the diameter of the reinforcing bar to be locked, It is preferable to set it to be slightly smaller than this.

For example, when using a D10 reinforcing bar, it is preferable to set the holding width to about 8.5 mm. Similarly, when the reinforcing bar of D13 is used, the holding width is preferably about 11.5 mm, and in the case of D16, D19 and D22, the holding width is preferably about 15 mm, 18 mm and 21 mm, respectively.

However, in the case of locking a reinforcing bar having a diameter larger than the clamping width, pressing and inserting the reinforcing bar into the lateral clamping space causes the torsion spring part to elastically deform, and the second vertical reinforcing bar and the torsion spring. By firmly sandwiching the reinforcing bar with the part, it can be firmly locked.

Therefore, when the sandwiching width is set to, for example, about 8.5 mm, not only the reinforcing bar of D10 but also the reinforcing bar of D13 can be locked, and when the reinforcing bar of D13 is used, it is more firmly engaged. You can stop.

More specifically, in the reinforcing bar crossing clip according to the present embodiment, the linear first horizontal bar locking bar 111, the quarter arc-shaped first horizontal bar locking corner 112, and the linear first vertical bar holding. Bar 131, semi-arcuate vertical bar embracing corner 133, linear second vertical bar embracing bar 132, substantially quarter arc arc second horizontal bar engaging corner 122, linear second horizontal bar engaging bar 121, The spiral torsion spring portion 140, the linear vertical bar hooking lever 152, the semi-circular vertical bar hooking corner 153, and the linear vertical bar hooking bar 151 are arranged in the order of arrangement described in this paragraph. It is configured as one.

As shown in FIG. 2C and FIG. 2D, while the second connecting angle β formed by the second horizontal bar locking bar 121 and the tangential direction of the vertical bar embracing corner 133 is configured to be substantially right angle, The first connecting angle α formed by the first horizontal bar locking bar 111 and the tangential direction of the vertical bar holding corner 133 is configured to be slightly smaller than the second connecting angle β.

As shown in FIG. 2A, the second vertical holding bar 132 and the second horizontal locking bar 121 are configured so that the second locking angle δ is substantially right, while in FIG. 2B. As shown, the first locking angle γ formed by the first vertical bar embracing bar 131 and the first horizontal bar locking bar 111 is configured to be slightly smaller than the second locking angle δ. ..

As shown in FIG. 2A, the vertical bar hooking lever 152 is configured to incline to the second horizontal bar locking bar 121 on the side opposite to the torsion spring portion 140. More specifically, the arm angle ε formed by the vertical bar hooking lever 152 and the second horizontal bar locking bar 121 is configured to be an angle slightly smaller than two right angles.

As shown in FIGS. 2C and 2D, the vertical streak engaging angle ζ formed by the vertical stirrup lever 152 and the vertical streak bar 151 is slightly larger than 0 degree, that is, a J-shape. It is configured so that the space between the two becomes a slight opening angle.

As shown in FIG. 2A and FIG. 2B, the torsion spring portion 140 is arranged so as to face the second vertical bar embracing bar 132, and the torsion spring portion 140, the second horizontal bar locking corner 122, and the second vertical bar. The muscle holding bar 132 forms a horizontal muscle holding space RS for holding the horizontal muscle.

Next, a procedure for locking mutually orthogonal reinforcing bars by using the reinforcing bar crossing clip 100 according to the present embodiment will be described. Here, as shown in FIG. 3A, an example will be described in which the horizontal muscle TR is locked to the vertical muscle LB at a predetermined height on the front side of the vertical muscle LB.

First, the horizontal muscle TR is lifted up to a predetermined height with respect to the vertical muscle LB, and the vertical muscle holding corner 133 is applied to the vertical muscle LB from the back side of the vertical muscle LB at a position higher than the horizontal muscle TR. The locking bar 111 and the second horizontal bar locking bar 121 are lowered to a position where they come into contact with the horizontal bar TR.

Here, when the vertical muscle embracing portion 130 holds the vertical muscle LB and is positioned so that the first horizontal muscle locking bar 111 abuts the horizontal muscle TR, the second vertical muscle embracing bar 132 and the second horizontal muscle engagement bar 132. The second locking angle δ formed by the stop bar 121 is configured to be substantially a right angle, while as shown in FIG. 2B, the first vertical bar retaining bar 131 and the first horizontal bar locking bar 111. Since the first locking angle γ formed by and is configured to be slightly smaller than the second locking angle δ, the second horizontal bar locking bar 121 is arranged at a position slightly floating from the horizontal bar TR. Will be done.

Since the distance between the second vertical strip embracing bar 132 and the torsion spring portion 140, that is, the sandwiching width of the horizontal strip sandwiching space RS is configured to be slightly smaller than the diameter of the horizontal strip TR , the horizontal strip TR is placed within the horizontal strip sandwiching space RS. In order to insert it, it is necessary to press the second horizontal bar locking bar 121 in the direction of the horizontal bar TR for fitting.

Therefore, the vertical streak latch lever 152, which is configured to incline to the side opposite to the torsion spring portion 140 with respect to the second horizontal streak locking bar 121 and is located on the front side of the vertical streak LB, moves the vertical streak lever 152. if pressed closer to LB, the horizontal stripes TR, makes easily fitting the lateral stripes clamping space RS that is formed by the torsion spring portion 140 and the second lateral stripes locking corners 122 and the second vertical stripe retaining bar 132 You can

At this time, the torsion spring portion 140 is elastically deformed and comes into contact with the lateral stripe at the horizontal streak pressing contact 141, but due to the restoring force of the torsion spring section 140, the torsion spring section 140 and the second vertical bar holding bar 132. With, the lateral muscle TR is firmly clamped.

Then, as shown in FIG. 3B, if the vertical streak hooking lever 152 is further pushed to the back side of the vertical streak bar LB, and the tip of the vertical streak bar 151 is wound around the vertical streak bar LB, Since the vertical streak hook angle ζ formed by the vertical streak bar 151 with respect to the lever 152 is set to open to about 5 degrees, the vertical streak corner 153 is set by the restoring force of the torsion spring portion 140. It is possible to deform the LB to a position in which it abuts from the back side and to hang the vertical bar hooking portion 150, and the vertical bar hooking bar 151 and the vertical bar hooking lever 152 sandwich the vertical bar LB, and the horizontal bar TR. The vertical streak LB is firmly locked.

The size of the first locking angle γ, which is formed substantially at a right angle, when the vertical bar hooking portion 150 is wound around, the second locking angle δ decreases due to elastic deformation of the second horizontal bar locking corner 122. Since the first horizontal muscle locking portion 110 and the second horizontal muscle locking portion 120 have substantially the same shape when viewed from the axial direction of the horizontal muscle TR, the horizontal muscle TR can be pressed and balanced in a balanced manner. it can.

Further, when the vertical bar hooking portion 150 is wound around, the first connecting angle α increases due to the elastic deformation of the first horizontal bar locking corner 112, and the size of the second connecting angle β is formed substantially at a right angle. , The first horizontal muscle locking portion 110 and the second horizontal muscle locking portion 120 have substantially the same shape when viewed from the direction orthogonal to both the vertical muscle LB and the horizontal muscle TR, and press the horizontal muscle TR, Further, it can be locked with a good balance.

Next, a clip for a reinforcing bar crossing portion, which is another embodiment of the present invention, will be described with reference to FIG.

FIG. 4 is a schematic diagram showing a state in which a main bar and a stirrup bar are mutually locked by using a clip for a reinforcing bar crossing portion which is another embodiment of the present invention.

As shown in FIG. 4, a method of using the reinforcing bar intersection clip 100 of the present invention will be described when the ribs RR among the intersections of the main bars MR and the stirrups RR forming the beam are bent. To do.

When the ribs RR are bent at the intersection of the main muscles MR and the ribs RR, as shown in FIG. 4, the longitudinal muscles LB and the transverse muscles TR in Example 1 are respectively changed to the ribs RR and the main muscles MR. By replacing, it can be locked as in the first embodiment.
That is, even at the intersection where one of the reinforcing bars is bent, locking can be performed using the reinforcing bar intersection clip 100 having exactly the same shape as the case where the linear reinforcing bars intersect.
