There are things to do. Furthermore, a handrail may be installed by fixing a column to a scaffold or a supporting work installed in advance.

JP-A-8-82102

  Since the mounting bracket described above is embedded in concrete, once embedded, it is very difficult to remove. Therefore, this mounting bracket has a problem that it cannot be easily attached to and detached from the reinforcing bars and cannot be diverted. Moreover, since each handrail mentioned above is removed at the time of slab formwork laying, the state without a safety fence will arise temporarily. Therefore, there is a problem that safety cannot be sufficiently ensured.

  An object of this invention is to provide the attachment metal fitting which can perform attachment or detachment with respect to a reinforcing bar easily, and can fully ensure safety | security, and the attachment method of an attachment metal fitting.

  A mounting bracket according to the present invention is a mounting bracket that is attached to a plurality of reinforcing bars arranged side by side, a base portion, a first folded portion that is folded at one end of the base portion and sandwiches the first reinforcing rod, and a base portion A distance between the first end of the base portion and the first tip of the first folded portion in the juxtaposition direction of the first reinforcing bar and the second reinforcing bar. Is L1, and the distance from the other end of the base portion to the second tip of the second folded portion is L2, L1 <L2 is satisfied.

  The mounting bracket is a mounting bracket that is attached to a plurality of reinforcing bars arranged side by side, and includes a first folded portion that sandwiches the first reinforcing bar and a second folded portion that sandwiches the second reinforcing bar. And in the parallel arrangement direction of a plurality of reinforcing bars, the distance from one end of the base part to the first tip of the first folded part is shorter than the distance from the other end of the base part to the second tip of the second folded part. ing. Therefore, the second rebar is first sandwiched by the long second folded portion, and then the mounting bracket is tilted to insert the first rebar between the first tip and the second tip, and the mounting bracket is slid to move the first folded portion. By attaching the first reinforcing bar, the mounting bracket can be easily attached to the reinforcing bar. When removing the mounting bracket from the plurality of reinforcing bars, the mounting bracket is slid to release the first reinforcing bar from being sandwiched by the first folding part, and then the mounting bracket is tilted to remove the second folding part from the second reinforcing bar. Since it is good, a mounting bracket can be easily removed from a plurality of reinforcing bars. Thus, since the mounting bracket is detachable, the mounting bracket can be diverted. Moreover, in the state which attached the attachment bracket to the 1st reinforcing bar and the 2nd reinforcing bar, since the 1st folding | returning part has pinched | interposed the 1st reinforcing bar and the 2nd folding | returning part has pinched the 2nd reinforcing bar, it is the 1st reinforcing bar. And rotation of the mounting bracket with respect to the second rebar is prevented. Therefore, a situation in which the mounting bracket rotates and comes off is prevented, so that safety can be ensured. Furthermore, since the length of the second folded portion is longer than the length of the first folded portion, the distance from the first reinforcing bar to the second reinforcing bar can be given a degree of freedom. That is, even if the distance from the first reinforcing bar to the second reinforcing bar is different, the reinforcing bars can be sandwiched by the folded portions, and can be attached to a plurality of reinforcing bars having different pitches. Can be attached.

  As a specific form that exhibits the above-described effects, in the parallel arrangement direction described above, one end of the first reinforcing bar located on the opposite side of the second reinforcing bar, and the other end of the second reinforcing bar located on the opposite side of the first reinforcing bar, , X1 is the distance between the first tip and the second tip, X2 is the distance between the inner surface of the other end of the base portion and the first tip, and X1 <Y1 and Y1 <X2. The structure which satisfy | fills is mentioned.

  Further, a third reinforcing bar is provided between the first reinforcing bar and the second reinforcing bar, and the interval between the first reinforcing bar and the third reinforcing bar is the same as the interval between the third reinforcing bar and the second reinforcing bar. When the interval between the second reinforcing bar and the third reinforcing bar is Y2 in the juxtaposed direction, L2 <Y2 may be satisfied. In this case, even if the third reinforcing bar is arranged between the first reinforcing bar and the second reinforcing bar, the mounting bracket can be attached, and the mounting bracket can be attached to a plurality of reinforcing bars having a finer pitch. it can.

  Moreover, the base part may be provided with the support | pillar attaching part to which the support | pillar of a fence is attached. As described above, since the situation in which the mounting bracket rotates and disengages is prevented, it is possible to avoid the situation in which the strut is detached from the reinforcing bar when the fence strut is attached to the strut mounting portion. Therefore, the safety in the fence can be improved.

  The mounting method according to the present invention includes a base portion, a first folded portion that is folded at one end of the base portion and sandwiches the first reinforcing bar, and a second folded portion that is folded at the other end of the base portion and sandwiches the second reinforcing bar. , A step of fitting the second folded portion into the second reinforcing bar, and a second folded portion of the second folded portion with the second folded portion fitted into the second reinforcing bar. A step of putting the first reinforcing bar between the second tip and the first tip of the first folded portion, and sliding the mounting bracket in a state where the first reinforcing bar is put between the second tip and the first tip, Maintaining the state where the second folded portion is fitted into the second reinforcing bar, and fitting the first folded portion into the first reinforcing bar. In this mounting method, the mounting bracket can be easily mounted on a plurality of reinforcing bars, and the same effect as the mounting bracket described above can be obtained.

  According to the present invention, it is possible to easily attach and detach the reinforcing bar, and it is possible to sufficiently ensure safety.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the description of the drawings, the same or equivalent elements are denoted by the same reference numerals, and redundant description is omitted.

  As shown in FIG. 1, the mounting bracket 1 according to the present embodiment is attached to the upper side in the vertical direction of a plurality of reinforcing bars F that are assembled vertically and horizontally. The mounting bracket 1 supports the column P on the reinforcing bar F by fitting with the column P of the fence H which is a handrail installed on the reinforcing bar F. The support P is, for example, cylindrical. A plurality of mounting brackets 1 are mounted on the reinforcing bar F, and the fence H is installed on the reinforcing bar F by fitting each of the plurality of support posts P to each of the plurality of mounting brackets 1. In addition, although the two cross members L spanned by the some support | pillar P are provided in the fence H, about the shape and magnitude | size of a fence, it can change suitably.

  As shown in FIGS. 2 and 3, the mounting bracket 1 includes a base portion 2 formed in a plate shape, a plate-like first folded portion 3 folded from one end E <b> 1 of the base portion 2, and a base portion 2. And a plate-like second folded portion 4 folded from the other end E2. Here, the base portion 2 is formed so as to extend in the direction D, and the direction D is a parallel arrangement direction of the plurality of reinforcing bars F to which the mounting bracket 1 is attached. For example, the base part 2, the first folded part 3, and the second folded part 4 all have the same width. The base part 2 and the first folded part 3 are formed by bending a single iron plate member. And the 2nd folding | turning part 4 is formed.

  The base portion 2 has, at both ends, a bending portion 2a that curves toward one end E1, and a bending portion 2b that curves toward the other end E2. The curved portions 2a and 2b have, for example, an arc shape, and the central angle of the arc portion is 90 degrees. Moreover, the base part 2 has the extension part 2c extended in the direction D between curved part 2a, 2b, and this extension part 2c is extended linearly.

  The 1st folding | turning part 3 has the curved part 3a extended from the end E1, and the extended part 3b extended in the direction D from the curved part 3a. The curved portion 3a has, for example, an arc shape, and the central angle of the arc portion is 90 degrees. The curved portion 3a of the first folded portion 3 is continuous with the curved portion 2a of the base portion 2 through one end E1, and forms a U-shaped portion folded back by 180 degrees between the curved portion 3a and the curved portion 2a. Yes. The extending part 3b extends linearly in the direction D from the end of the curved part 3a located on the opposite side of the one end E1.

  The second folded portion 4 has a curved portion 4a extending from the other end E2, and an extending portion 4b extending in the direction D from the curved portion 4a. The shape of the bending portion 4a is, for example, the same as the shape of the bending portion 3a, and the bending portion 4a of the second folded portion 4 is continuous with the bending portion 2b of the base portion 2 via the other end E2. The curved portion 4a and the curved portion 2b form a U-shaped portion that is folded back by 180 degrees. The extending part 4b extends linearly in the direction D from the end of the curved part 4a located on the opposite side of the other end E2.

  A U-shape formed by the curved portion 3a of the first folded portion 3 and the curved portion 2a of the base portion 2, and a U-shaped formed by the curved portion 4a of the second folded portion 4 and the curved portion 2b of the base portion 2. The character portions have the same curvature, for example, and have a curvature that can hold one reinforcing bar F. Further, the length of the extending portion 4 b of the second folded portion 4 is longer than the length of the extending portion 3 b of the first folded portion 3. That is, in the direction D, the distance from one end E1 of the base portion 2 to the first tip 3c of the first folded portion 3 (extending portion 3b) is equal to the second folded portion 4 (extending portion) from the other end E2 of the base portion 2. It is shorter than the distance to the 2nd front-end | tip 4c of the part 4b). Specific distances and the like in each part of the first folded part 3 and the second folded part 4 will be described in detail later.

  The base portion 2 includes a column attachment portion 2d to which the column P of the fence H is attached. The column attachment portion 2d is fixed to, for example, a surface on the upper side (outside or opposite to the first folded portion 3 and the second folded portion 4) of the extending portion 2c of the base portion 2, and the extending portion 2c. It has a cylindrical shape extending upward. The column attachment portion 2d is provided at the center portion in the direction D of the extending portion 2c. The strut mounting portion 2d is provided with a notch 2f formed in an L shape so as to extend downward from the upper end 2e and bend in the circumferential direction. The two notches 2f are the center of the strut mounting portion 2d. It arrange | positions in the position which becomes mutually symmetrical with respect to an axis.

  The outer diameter of the column mounting part 2d is slightly smaller than the inner diameter of the column P, and the column P is attached to the mounting bracket 1 by fitting the column P outside the column mounting part 2d. Specifically, a linear pin inserted through a hole penetrating in the direction perpendicular to the axis of the column P is fixed inside the cylindrical column P, and the column P is placed on the column mounting portion 2d. And the pins of the pillars P are notched into the notches 2f from above and the pillars P are rotated in the circumferential direction. As a result, when the column P is pulled up from the column mounting portion 2d, the pin inside the column P contacts the upper wall of the lower side portion (the portion extending in the circumferential direction) of the notch 2f. The column P is prevented from coming off from the portion 2d.

  As described above, it is possible to fit the column P into the column mounting portion 2d, but the shape, specific mounting structure, and arrangement position of the column mounting portion are not limited to the above example. For example, after the support P is fitted into the support mounting part, the support P may be fixed to the support mounting part by bolting.

  Further, the base portion 2 has a circular insertion hole 2g through which a bolt B for fixing the reinforcing bar F is inserted. In the base portion 2, the insertion hole 2 g is disposed on the first folding portion 3 side with respect to the column attachment portion 2 d, and the bolt B inserted through the insertion hole 2 g enters the first folding portion 3 and the reinforcing bar F <b> 1 (FIG. 7)) from above. Specifically, a nut N is disposed on the upper side of the insertion hole 2g, and a bolt B is screwed onto the nut N from the upper side, the bolt B is inserted into the insertion hole 2g, and the reinforcing bar F1 is pressed at the tip of the bolt B. As a result, the reinforcing bar F1 is held.

  Next, distances of the respective parts of the base part 2, the first folded part 3 and the second folded part 4 and each distance in the reinforcing bar F will be described with reference to FIG. First, in the direction D in which the plurality of reinforcing bars F are arranged side by side, the distance from one end E1 of the base portion 2 to the first tip 3c of the first folded portion 3 is L1, and the other end E2 of the base portion 2 is second folded. When the distance to the second tip 4c of the portion 4 is L2, L1 <L2 is satisfied. More specifically, L1 is the distance from the inner surface 2k of the one end E1 to the first tip 3c, and L2 is the distance from the inner surface 2h of the other end E2 to the second tip 4c.

  Further, the reinforcing bars F are assembled in advance vertically and horizontally as described above, and are assembled at a predetermined interval (pitch) Y2, for example. Here, the mounting bracket 1 is attached to the reinforcing bars F1 and F2 located at both ends of the plurality of (three) reinforcing bars F adjacent to each other. That is, the mounting bracket 1 is mounted on the reinforcing bar F in a state where a plurality of reinforcing bars F are bridged over the plurality of reinforcing bars F. Below, among the three reinforcing bars F arranged, the reinforcing bar F located at one end is provided between the first reinforcing bar F1 and the reinforcing bar F located at the other end is provided between the second reinforcing bar F2 and the first reinforcing bar F1 and the second reinforcing bar F2. The reinforcing bar F is defined as a third reinforcing bar F3. Note that the interval between the first reinforcing bar F1 and the third reinforcing bar F3 and the interval between the third reinforcing bar F3 and the second reinforcing bar F2 are the same interval Y2.

  First, in the direction D, the distance between one end G1 located on the opposite side of the second reinforcing bar F2 in the first reinforcing bar F1 and the other end G2 located on the opposite side of the first reinforcing bar F1 in the second reinforcing bar F2 is Y1, When the distance between the first tip 3c of the first folded portion 3 and the second tip 4c of the second folded portion 4 is X1, X1 <Y1 is satisfied. Thereby, while the 1st rebar F1 enters the 1st return part 3, the state where the 2nd rebar F2 entered the 2nd return part 4 is realized.

  Further, in the direction D, when the distance between the inner side surface 2h of the other end E2 of the base portion 2 and the first tip 3c of the first folded portion 3 is X2, Y1 <X2 is satisfied. Here, the inner side surface 2 h of the other end E <b> 2 of the base portion 2 indicates a portion located closest to the other end E <b> 2 among the inner side surfaces of the base portion 2. As a result, the first reinforcing bar F1 and the second reinforcing bar F2 are surrounded by the base part 2, the first folding part 3 and the second folding part 4 (the base part 2, the first folding part 3 and the second folding part 4 are surrounded. In the space). Further, in the direction D, the relationship between the distance L2 from the other end E2 of the base portion 2 to the second tip 4c of the second folded portion 4 and the interval Y2 that is the pitch of the reinforcing bars is L2 <Y2. .

  Since the distance between the parts of the mounting bracket 1 and the distances of the reinforcing bars F1, F2, and F3 are as described above, the mounting bracket 1 can be easily attached to the reinforcing bars F1, F2, and F3 without deformation. It is supposed to be. Below, the attachment method of this embodiment which attaches the attachment metal fitting 1 to the reinforcing bars F1, F2, F3 will be described with reference to FIGS. In FIGS. 5 to 7, for ease of illustration, the column attaching portion 2 d, the insertion hole 2 g, the bolt B and the nut N are omitted.

  First, as shown in FIG. 5, the mounting bracket 1 is tilted with respect to the direction D so that the first folded portion 3 is positioned upward, and the second folded portion 4 is hooked on the reinforcing bar F2. Specifically, the second reinforcing bar F2 is inserted into the U-shaped part formed by the curved part 4a of the second folded part 4 and the curved part 2b of the base part 2, and the second folded part 4 is hooked on the reinforcing bar F2 ( Step of fitting the second folded portion 4 into the second rebar F2).

  Next, as shown in FIG. 6, the first reinforcing bar F <b> 1 is inserted between the second tip 4 c and the first tip 3 c with the second folded portion 4 fitted into the second reinforcing bar F <b> 2. That is, the mounting bracket 1 is laid along the direction D and the reinforcing bars F1 and F3 are inserted between the first tip 3c and the second tip 4c (the first reinforcing bar between the second tip 4c and the first tip 3c). Step of inserting F1).

  Then, as shown in FIG. 7, the mounting bracket 1 is slid to the reinforcing bar F2 side and the first folded part 3 is hooked on the reinforcing bar F1 (step of fitting the first folded part 3 into the first reinforcing bar F1). In the state shown in FIG. 7, the mounting bracket 1 is hooked on the two reinforcing bars F1 and F2, and the rotation of the mounting bracket 1 with respect to the reinforcing bars F1 and F2 is prevented. Thereafter, the bolt B is screwed into the nut N and inserted into the insertion hole 2g, and the rebar F1 is pressed from above with the bolt B, whereby the attachment of the mounting bracket 1 to the rebars F1, F2, F3 is completed.

  In addition, after the attachment of the plurality of mounting brackets 1 to the reinforcing bars F1, F2, and F3 is completed, the fence H is formed by attaching the pillars P to the respective pillar attachment portions 2d and attaching the cross members L to the pillars P. Is done. Moreover, as a method of removing the mounting bracket 1 from the reinforcing bars F1, F2, and F3, the mounting bracket 1 is slid to the first folding portion 3 side to remove the first folding portion 3 from the first reinforcing bar F1, and then the first folding is performed. If the part 3 is lifted and the 2nd folding | returning part 4 is removed from the 2nd reinforcing bar F2, it will be completed.

  Next, the function and effect obtained by the mounting bracket 1 will be described. First, the mounting bracket 1 is attached to a plurality of reinforcing bars F1, F2, and F3, and includes a first folded part 3 that sandwiches the first reinforcing bar F1 and a second folded part 4 that sandwiches the second reinforcing bar F2. In the direction D, the distance from one end E1 of the base portion 2 to the first tip 3c of the first folded portion 3 is greater than the distance from the other end E2 of the base portion 2 to the second tip 4c of the second folded portion 4. Is also shorter.

  Therefore, the second rebar F2 is first sandwiched by the long second folded portion 4, and then the mounting bracket 1 is tilted so that the first rebar F1 and the third rebar F3 are inserted between the first tip 3c and the second tip 4c. The mounting bracket 1 can be easily attached to the reinforcing bars F1, F2, and F3 by sliding the mounting bracket 1 and sandwiching the first reinforcing bar F1 between the first folded portions 3. Furthermore, since the base part 2, the 1st folding | returning part 3, and the 2nd folding | turning part 4 form the U-shaped part, the attachment to the rebar F smooth is possible. Moreover, in the mounting bracket 1 of this embodiment, when mounting the mounting bracket 1 to the reinforcing bars F1, F2, F3, it is not necessary to deform the mounting bracket 1 itself. That is, in this embodiment, it is not assumed that the mounting bracket 1 itself is deformed and attached to the reinforcing bars F1, F2, and F3.

  When removing the mounting bracket 1 from the plurality of reinforcing bars F1, F2, F3, the mounting bracket 1 is tilted after the mounting bracket 1 is slid to release the first reinforcing bar F1 from being pinched by the first folded portion 3. Since the 2nd folding | returning part 4 should just be removed from 2 rebar F2, the attachment metal fitting 1 can be easily removed from the some rebar F1, F2, F3. Therefore, since the mounting bracket 1 is detachable, the mounting bracket 1 can be diverted.

  Further, in a state where the mounting bracket 1 is attached to the first reinforcing bar F1 and the second reinforcing bar F2, the first folded part 3 sandwiches the first reinforcing bar F1 and the second folded part 4 sandwiches the second reinforcing bar F2. Therefore, rotation of the mounting bracket 1 with respect to the first reinforcing bar F1 and the second reinforcing bar F2 is prevented. Therefore, the mounting bracket 1 is prevented from rotating and coming off, so that safety can be ensured.

  Furthermore, since the length of the 2nd folding | turning part 4 is longer than the length of the 1st folding | turning part 3, it can give a freedom degree to the distance from the 1st reinforcing bar F1 to the 2nd reinforcing bar F2. That is, the distance from the 1st reinforcing bar F1 to the 2nd reinforcing bar F2 can be changed in the range in which the 2nd reinforcing bar F2 enters the 2nd folding | returning part 4. FIG. As described above, even when the distance from the first reinforcing bar F1 to the second reinforcing bar F2 is different, the folded bars 3 and 4 can sandwich the reinforcing bars F1 and F2, and a plurality of reinforcing bars having different intervals (pitch) Y2 can be obtained. Since attachment becomes possible, the attachment metal fitting 1 can be attached to various reinforcing bars.

  In the direction D, the relationship between the distance L2 from the other end E2 of the base portion 2 to the second tip 4c of the second folded portion 4 and the distance Y2 between the second reinforcing bar F2 and the third reinforcing bar F3 is expressed as L2 < Y2 is satisfied. Accordingly, the mounting bracket 1 can be mounted even if the third reinforcing bar F3 is disposed between the first reinforcing bar F1 and the second reinforcing bar F2, so that the mounting bracket can be attached to a plurality of reinforcing bars having a finer pitch. 1 can be attached.

  Moreover, the base part 2 is provided with the support | pillar attaching part 2d to which the support | pillar P of the fence H is attached. As described above, since the situation in which the mounting bracket 1 rotates and disengages is prevented, it is possible to avoid the situation in which the support P is detached from the reinforcing bar F when the support P of the fence H is attached to the support mounting part 2d. Therefore, the safety in the fence H can be improved.

  Moreover, the attachment method of the attachment metal fitting of this embodiment is an attachment method which attaches the attachment metal fitting 1 to a plurality of reinforcing bars, the step of fitting the second folded portion 4 into the second reinforcing bar F2, and the second folded portion 4 The step of inserting the first reinforcing bar F1 between the second tip 4c and the first tip 3c in a state of being fitted to the second reinforcing bar F2, and the first reinforcing bar F1 between the second tip 4c and the first tip 3c. The mounting bracket 1 is slid in the inserted state to maintain the state where the second folded portion 4 is fitted to the second reinforcing bar F2, and the first folded portion 3 is fitted to the first reinforcing bar F1. In this attachment method, the attachment fitting 1 can be easily attached to the reinforcing bars F1, F2, F3, and the same effect as described above can be obtained.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to the above-mentioned embodiment, It deform | transformed in the range which does not change the summary described in each claim, or applied to others It may be a thing. That is, the present invention can be variously modified without changing the gist of each claim.

  For example, in the above-described embodiment, the insertion hole 2g of the base portion 2 is disposed on the first folded portion 3 side, and the bolt B is screwed into the reinforcing bar F1 that has entered the first folded portion 3, whereby the mounting bracket 1 is attached. Attached. However, the position, shape, and size of the bolt and the insertion hole can be changed as appropriate.

  For example, as shown in the mounting bracket 11 according to the first modification of FIG. 8, an insertion hole 2j positioned on the second folded portion 4 side is provided instead of the insertion hole 2g positioned on the first folded portion 3 side. It may be done. In this case, the bolt B is screwed into the reinforcing bar F <b> 2 that has entered the second folded portion 4, whereby the mounting bracket 11 is attached. Moreover, since the insertion hole 2j is a long hole extending in the direction D, the mounting bracket 11 can be attached to reinforcing bars having various pitches.

  In the above-described embodiment, the mounting bracket 1 having the cross section shown in FIG. 4A has been described, and the relationship among the distance X1, the distance X2, the distance Y1, and the distance Y2 has been described. FIG. 4A shows a cross section of the base portion 2, the first folded portion 3 and the second folded portion 4 cut along a plane extending in the vertical direction and in the direction D. All the cut parts have cross sections shown in FIG.

  However, the mounting bracket 1 does not have to have the cross section shown in FIG. That is, as shown in the second to fourth modifications described later, the mounting bracket 1 may partially have a cross-sectional shape different from that in FIG. 4A, and the distance X1 and distance X2 described above. And may have a portion that does not satisfy the relationship between the distance Y1 and the interval Y2. Thus, the shape of the mounting bracket 1 is not limited to the embodiment described above, and can be changed as appropriate.

  For example, the mounting bracket 31 of the second modification of FIG. 9A includes a first folded portion 33 and a second folded portion 34, and the cross section cut in the vertical vertical direction and in the direction D is a reinforcing bar F1, It differs depending on the position in the extending direction of F2. The first folded portion 33 includes an extending portion 33b that extends along the reinforcing bars F1 and F2 and a hooking portion 33a that protrudes inward from the extending portion 33b and is hooked on the reinforcing bar F1. The second folded portion 34 also has a similar extending portion 34b and hooking portion 34a. When viewed from below, the first folded portion 33 and the second folded portion 34 are both L-shaped. Yes.

  Further, in the mounting bracket 41 of the third modified example of FIG. 9B, the first folded portion 43 includes a protruding portion 43a that curves and protrudes from the end side toward the central side. The reinforcing bar F1 is hooked on the portion 43a. On the other hand, the second folded portion 44 of the mounting bracket 41 extends linearly in the diagonal direction of the reinforcing bars F1 and F2 from one end to the other end, and the reinforcing bar F2 protrudes from the second folded portion 44 inside. Is caught.

  Further, the mounting bracket 21 of the fourth modified example of FIG. 10 includes a base portion 22 that extends obliquely with respect to the reinforcing bars F <b> 1 and F <b> 2, a first folded portion 23 located at one end of the base portion 22, and the base portion 22. And a second folded portion 24 located at the end. The cross section obtained by cutting the base part 22, the first folded part 23, and the second folded part 24 in the vertical vertical direction and in the direction D differs depending on the positions of the reinforcing bars F1, F2 in the extending direction.

  As described above, in the mounting bracket according to the present invention, the length of the second folded portion is longer than the length of the first folded portion, and the second folded portion can be fitted first. The rebar F1 can be inserted between the two ends of each folded portion in the state of being fitted in F2, and the mounting bracket is slid to move the first folded portion with the reinforcing bar F1 inserted between the two ends. If it is possible to maintain the state where the second folded portion is fitted in the reinforcing bar F2 while keeping the fitting in the reinforcing bar F1, the shape can be changed as appropriate.

  Moreover, although the above-mentioned embodiment demonstrated the attachment metal fitting 1 attached to a reinforcing bar by the volt | bolt B being screwed in the reinforcing bar F, you may attach to a reinforcing bar by means other than the bolt B. For example, after the second rebar 4 is sandwiched by the second rebar F2 and the first rebar 3 is sandwiched by the first rebar F1, the mounting bracket may be attached by being tied to the rebar with a wire.

  In the above-described embodiment, the example in which the distance between the first reinforcing bar F1 and the third reinforcing bar F3 and the distance between the third reinforcing bar F3 and the second reinforcing bar F2 are the same is described. However, the distance between the first reinforcing bar F1 and the third reinforcing bar F3 and the distance between the third reinforcing bar F3 and the second reinforcing bar F2 may be different from each other.

  In the above-described embodiment, as illustrated in FIG. 4, the example in which the cross sections of the first reinforcing bar F1, the second reinforcing bar F2, and the third reinforcing bar F3 are circular has been described. Here, the diameters of the cross sections of the reinforcing bars F1, F2, and F3 may be the same or different from each other. Further, the cross section of each reinforcing bar F1, F2, F3 may be a shape other than a circle. Regardless of the cross-sectional shape and size of each of the reinforcing bars F1, F2, and F3, the interval Y2 between the second reinforcing bar F2 and the third reinforcing bar F3 is the end of the second reinforcing bar F2 opposite to the third reinforcing bar F3 (the other end). This corresponds to the distance between G2) and the end of the third reinforcing bar F3 on the second reinforcing bar F2 side.

  Further, the shapes of the base part 2, the first folded part 3 and the second folded part 4 can be changed as appropriate. The first folded portion 3 and the second folded portion 4 may not all have the same width. Moreover, the base part 2 does not need to have the support | pillar attaching part 2d. That is, in the above-described embodiment, the mounting bracket 1 that supports the support P on the reinforcing bar F has been described. However, the support target of the mounting bracket does not have to be the support P, and supports members other than the support of the fence. Also good.
