Description

The present invention relates to a horizontal reinforcing bar arrangement device that arranges horizontal bars in a position when binding multiple horizontal bars that extend horizontally to multiple vertical bars that extend vertically and are arranged side by side in the horizontal direction at their intersections.

Generally, at civil engineering and construction sites, multiple rebars are brought in together using a crane or similar device, and multiple workers ascend and descend a multi-story scaffold to place each rebar vertically and horizontally, one by one, and then tie together the multiple vertical bars that run vertically and the multiple horizontal bars that run horizontally at their intersections.

However, when multiple workers ascend and descend a multi-story scaffold to tie together multiple vertical and horizontal reinforcements that are arranged vertically and horizontally at their intersections, the arrangement directions of each vertical reinforcement and each horizontal reinforcement are perpendicular to each other, and the rebars themselves are heavy, so it is extremely difficult to position each vertical reinforcement and each horizontal reinforcement when tying them together at their intersections.

Therefore, a rebar handling device that uses a gripping device to grasp rebar and arrange it vertically and horizontally has been known to allow the vertical and horizontal rebars to be arranged freely regardless of the arrangement direction, and to easily position the rebars when tying them together at their intersections (see Patent Document 1).

Japanese Unexamined Patent Publication No. 64-87492

However, even with the above-mentioned conventional rebar handling devices, only one vertical rebar and one horizontal rebar can be placed with a single rebar. For example, even when placing horizontal rebars vertically for each vertical rebar that is erected horizontally, only one horizontal rebar can be placed for each vertical rebar, and the next horizontal rebar cannot be placed until the horizontal rebar has been placed and tied. For this reason, the placement of the next horizontal rebar must wait until the horizontal rebar, which can only be placed one at a time, has been tied at the intersection with multiple vertical rebars, resulting in extremely poor work efficiency.

The present invention was made in consideration of these points, and its purpose is to provide a horizontal reinforcing bar arrangement device that can arrange multiple vertical bars arranged side by side in the horizontal direction together with the horizontal bars positioned at their intersections with each vertical bar, thereby improving work efficiency when tying the bars together at the intersections.

In order to achieve the above object, the present invention is based on a horizontal reinforcing bar arrangement device that arranges horizontal reinforcing bars in a state where each horizontal reinforcing bar is positioned relative to each vertical reinforcing bar when multiple horizontal reinforcing bars extending in the horizontal direction are bundled at their intersections with multiple vertical reinforcing bars arranged in the horizontal direction. The device includes multiple support members that extend in the vertical direction while being lifted by a lifting device between the vertical reinforcing bars spaced apart by several bars in the horizontal direction, and multiple positioning jigs that are provided at equal intervals in the vertical direction of each support member and individually position each of the horizontal reinforcing bars in a state where they are arranged in the vertical direction. Each positioning jig also includes a temporary holding portion that temporarily holds each horizontal reinforcing bar relative to each support member, and a positioning means that positions the temporary holding portion so that each horizontal reinforcing bar is located at the intersection of each vertical reinforcing bar. The temporary holding section further comprises a generally U-shaped or generally C-shaped temporary holding section main body having an opening through which the horizontal bars can be inserted, and a bridging member that is hung between both ends of the temporary holding section main body to close the opening when the horizontal bars are inserted. The bridging member is hung between both ends of the temporary holding section main body to close the opening so as to temporarily hold the horizontal bars, while the opening of the temporary holding section main body is opened by an artificial operation to release the horizontal bars. In addition, a wing bolt is applied as the bridging member, which is inserted from one end of the temporary holding section main body on the upstream side in the insertion direction, and a bolt insertion hole or a nut member for screwing the wing bolt is provided on the other end of the temporary holding section main body on the downstream side in the insertion direction. The butterfly bolt is adapted to block the opening of the temporary holding portion main body by screwing it into the bolt insertion hole or the nut member, while the opening of the temporary holding portion main body is opened by an artificial action such as releasing the bolt insertion hole or the nut member from the bolt insertion hole or the nut member and removing it from the upstream side of the temporary holding portion main body in the insertion direction .

In contrast, in order to achieve the above-mentioned object, the present invention is based on a horizontal reinforcing bar arrangement device that arranges horizontal reinforcing bars in a state where each horizontal reinforcing bar is positioned relative to each vertical reinforcing bar when tying horizontal reinforcing bars at their intersections with each vertical reinforcing bar, and includes a plurality of support members that extend vertically while being lifted by a lifting device between adjacent vertical reinforcing bars spaced apart by several bars in the horizontal direction, and a plurality of positioning jigs that are provided at equal intervals in the vertical direction of each support member and individually position each of the horizontal reinforcing bars in a state where they are arranged vertically so that they can be arranged. Each positioning jig also includes a temporary holding part that temporarily holds each horizontal reinforcing bar relative to each support member, and a positioning means that positions the temporary holding part so that each horizontal reinforcing bar is located at the intersection of each vertical reinforcing bar. The temporary holding section further comprises a U-shaped or U-shaped temporary holding section main body having an opening through which the horizontal bars can be inserted, and a bridging member that is suspended between both ends of the temporary holding section main body so as to close the opening when the horizontal bars are inserted. The bridging member is suspended between both ends of the temporary holding section main body to temporarily hold the horizontal bars while closing the opening, while the bridging member is configured to release the horizontal bars while opening the temporary holding section main body by an artificial operation. The bridging member supports one longitudinal end of the temporary holding section main body via a bolt member that is screwed into a screw hole recessed in one end of the temporary holding section main body so as to be rotatable about the axis of the bolt member, and engages the other longitudinal end with a recess provided in the other end of the temporary holding section main body so as to close the opening between both ends of the temporary holding section main body. Furthermore, a screw member is screwed into a screw hole provided in the middle of the longitudinal direction of the hanging member until it abuts against the transverse bar inserted into the temporary-holding body. The hanging member is characterized in that the opening of the temporary-holding body is closed by screwing the screw member into the screw hole until it abuts against the transverse bar with the other longitudinal end of the hanging member engaged in a recess of the temporary-holding body, while the opening of the temporary-holding body is opened by an artificial operation such as rotating the screw member around the axis of the bolt member with the screw member loosened from the transverse bar.

In order to achieve the above object, the present invention is based on a horizontal reinforcing bar arrangement device that arranges horizontal reinforcing bars in a state where the horizontal reinforcing bars are positioned relative to the vertical reinforcing bars when tying the horizontal reinforcing bars at their intersections with the vertical reinforcing bars arranged in a horizontal direction, and includes a plurality of support members that extend vertically while being lifted by a lifting device between the vertical reinforcing bars spaced apart by several bars in the horizontal direction, and a plurality of positioning jigs that are provided at equal intervals in the vertical direction of the support members and individually position the horizontal reinforcing bars in a state where they are arranged vertically so that they can be arranged. Each of the positioning jigs also includes a temporary holding part that temporarily holds each of the horizontal reinforcing bars relative to each of the support members, and a positioning means that positions the temporary holding part so that each of the horizontal reinforcing bars is located at the intersection of each of the vertical reinforcing bars. The temporary holding section further comprises a temporary holding section main body having a generally U-shape or generally C-shape with an opening through which the horizontal bars can be inserted, and a bridging member that is hung between both ends of the temporary holding section main body to close the opening with the horizontal bars inserted therethrough. The bridging member is hung between both ends of the temporary holding section main body to close the opening so as to temporarily hold the horizontal bars, while the bridging member is hung between both ends of the temporary holding section main body to close the opening so as to release the horizontal bars with the opening of the temporary holding section main body opened by an artificial operation. The positioning means further comprises a positioning member that faces one side piece of the temporary holding section main body with the support member sandwiched therebetween, and a screwing means that immovably positions the temporary holding section main body by screwing it to the support member via the positioning member when the support member is lifted by the lifting device. Furthermore, the temporary holding portion is provided with a pair of long holes that are elongated in the left-right direction provided in the positioning member, a pair of long holes that are elongated in the left-right direction provided in one side piece of the temporary holding portion main body that faces each of the long holes of the positioning member, and a pair of long holes that are elongated in the left-right direction provided on the other side end side that faces the one side piece of the temporary holding portion main body. The hanging member has a pair of left and right legs, each of which is formed in an approximately hairpin shape, whose base ends are connected to a wound section formed by one turn so as to be biased in a direction so as to open the legs outward in the left-right direction, and is hung from one side end to the other side end of the temporary holding part body so as to close the opening of the temporary holding part body.The two legs are manually deformed in the closing direction against the biasing force of the hanging member, and are inserted from the long holes of the positioning member into the long holes of one side piece of the temporary holding part body and the long holes of the other side end of the temporary holding part body, and the manual deformation is released and the legs are engaged with the back edge of each of the long holes, thereby closing the opening of the temporary holding part body.On the other hand, the opening of the temporary holding part body can be opened by an artificial action of manually deforming the two legs in the closing direction against the biasing force, and then removing them from the positioning member and the long holes of the temporary holding part body to release them from the engagement with each of the long holes.

On the other hand, in order to achieve the above object, the present invention is based on a horizontal reinforcing bar arrangement device that arranges horizontal reinforcing bars in a state where the horizontal reinforcing bars are positioned relative to the vertical reinforcing bars when tying the horizontal reinforcing bars at their intersections with the vertical reinforcing bars arranged in a horizontal direction, and includes a plurality of support members that extend vertically while being lifted by a lifting device between the vertical reinforcing bars spaced apart by several bars in the horizontal direction, and a plurality of positioning jigs that are provided at equal intervals in the vertical direction of the support members and individually position the horizontal reinforcing bars in a state where they are arranged vertically so that they can be arranged. Each of the positioning jigs also includes a temporary holding part that temporarily holds each of the horizontal reinforcing bars relative to each of the support members, and a positioning means that positions the temporary holding part so that each of the horizontal reinforcing bars is located at the intersection of each of the vertical reinforcing bars. The temporary holding part further comprises a temporary holding part main body having an approximately U-shape or approximately C-shape with an opening through which the transverse bars can be inserted, and a bridging member that is hung between both ends of the temporary holding part main body to close the opening when the transverse bars are inserted. The bridging member is hung between both ends of the temporary holding part main body to temporarily hold the transverse bars while closing the opening, while the opening of the temporary holding part main body is opened by an artificial operation to release the transverse bars. The temporary holding part main body has a left-right extension part that is a long round steel bar having male screws at both ends and extends left-right along the transverse bars at the other end of the temporary holding part, and the left and right ends of the left-right extension part are bent toward one end of the temporary holding part in an approximately U-shape so that the opening is open so that the transverse bars can be inserted, and both ends extend upward along the support members. The bridging member is a long bolt member having a male screw at its tip and bridging from one side end of the temporary holding part body to the left-right extension at the other side end so as to close the opening of the temporary holding part body. The positioning means further includes a positioning member having a long hole through which the male screws at both ends of the temporary holding part body are inserted from below and through which the bolt member is inserted at one side end of the temporary holding part so as not to fall out, and a screwing means for screwing the temporary holding part body to the support member at equal intervals via the positioning member. The bolt member is adapted to close the opening of the temporary holding portion main body by inserting its head from the long hole of the positioning member at one side end of the temporary holding portion to the left-right extension portion at the other side end of the temporary holding portion and engaging it, while the opening of the temporary holding portion main body is opened by an artificial action of removing the head from the left-right extension portion and moving it to the long hole of the positioning member while releasing the engagement with the left-right extension portion.

In short, by providing multiple positioning jigs at equal intervals on multiple support members that extend vertically and are lifted by a lifting device between the vertical bars spaced apart from each other, arranged horizontally, the vertical bars are aligned vertically so that each horizontal bar can be positioned vertically. The temporary holding portion that temporarily holds each horizontal bar on each support member is positioned for each positioning jig by a positioning means so that each horizontal bar is positioned at its intersection with each vertical bar. This allows multiple horizontal bars to be positioned simultaneously at the intersections of each horizontal bar arranged horizontally, and each horizontal bar can be tied at the intersections of each vertical bar all at once, dramatically improving work efficiency.

In addition, by hanging a bridging member between both ends of the temporary holding part body with each horizontal bar inserted so as to close the opening, the temporary holding of the horizontal bar in each temporary holding part can be easily performed by attaching and detaching the bridging member.

Furthermore, by abutting the peripheral portion of the insertion hole of the temporary holding part, which opens to allow each support member to be inserted, against the locking devices installed at equal intervals on each support member, the temporary holding part is positioned so that it cannot move downward. This makes it possible to easily position the temporary holding part relative to each support member lifted by the lifting device, and with a simple configuration, each horizontal bar can be reliably positioned at the intersection with each vertical bar.

In addition, by providing the positioning means with screwing means for screwing the temporary holding part main body to the support members at equal intervals, it is not only possible to easily position the temporary holding part with respect to each support member lifted by the lifting device, but it is also easy to accommodate changes in the spacing of each cross bar.

The following describes a horizontal reinforcing bar arrangement device according to an embodiment of the present invention with reference to the drawings.

Figure 1 is a rear view showing the state in which each transverse reinforcement is temporarily held by multiple positioning jigs of the transverse reinforcement arrangement device according to the first embodiment of the present invention, and Figure 2 shows a left side view of the transverse reinforcement arrangement device of Figure 1 as seen from the left side.

In these figures, the horizontal reinforcing bar arrangement device, designated by reference number 1, comprises two wire members 2, 2 as support members extending vertically while being lifted by a lifting device (not shown) such as a crane, and a number of positioning jigs 3, 3, ... (24 in Figs. 1 and 2) that are provided at equal intervals (e.g., about 150 to 300 mm) on each wire member 2 and individually position a number of horizontal bars Y, Y, ... (24 in Figs. 1 and 2) arranged in a vertical line. Each wire member 2 is supported at intervals by a long support rod (not shown) in the horizontal direction and is lifted by the lifting device. At this time, the support rod is set longer than the length between the two temporary holding points of each horizontal bar Y temporarily held by the two positioning jigs 3, 3.

Figure 3 is a perspective view of the positioning jig in the horizontal reinforcing bar arrangement device 1 in Figure 1, and Figure 4 is a right side view of the positioning jig 3 in Figure 3 as seen from the right side. Also, Figure 5 is a rear view of the positioning jig 3 in Figure 4 as seen from the rear side, and Figure 6 is a plan view of the positioning jig 3 in Figure 4 as seen from above.

As shown in Figures 3 to 6, each positioning jig 3 is equipped with a temporary holding portion 31 that temporarily holds each horizontal bar Y to each wire member 2, and a positioning means 4 that positions this temporary holding portion 31 so that each horizontal bar Y is located at the intersection K with each vertical bar T (described later). In this case, each horizontal bar Y and each vertical bar T is made of deformed steel bar of D32 (nominal diameter 31.8 mm, outermost diameter 36 mm).

The temporary holding part 31 includes a generally U-shaped temporary holding part main body 32 with an opening that allows the horizontal bar Y to be inserted therethrough, and a butterfly bolt 33 as a bridging member that is hung between both ends of the temporary holding part main body 32 to close the opening with the horizontal bar Y inserted therethrough. In addition, bolt insertion holes 34, 35 are provided at both ends of the temporary holding part main body 32, and the butterfly bolt 33 is inserted through the bolt insertion hole 34 on the upstream side in the insertion direction, which is one end of the temporary holding part main body 32 (the right end in Figs. 4 and 6), and is screwed into the bolt insertion hole 35 on the downstream side in the insertion direction, which is the other end of the temporary holding part main body 32 (the left end in Figs. 4 and 6). At this time, the bolt insertion hole 34 on the upstream side in the insertion direction is formed as a large diameter hole into which the wing bolt 33 cannot be screwed, and the wing bolt 33 that falls from the bolt insertion hole 34 on the upstream side in the insertion direction in a state in which it is released from being screwed into the bolt insertion hole 35 on the downstream side in the insertion direction is connected to the temporary holding part main body 32 by the wire 36 so that it cannot fall.

Both ends of the wire 36 are annular rings, and one ring at one end is engaged with the bolt insertion hole 34 on the upstream side in the insertion direction. Meanwhile, the other ring at the other end of the wire 36 is inserted into the shaft of the wing bolt 33 in a loose fit that does not allow it to rotate with the wing bolt, and is engaged between the wing bolt 33 and the head by a nut 37 screwed onto the base of the wing bolt 33 so that it cannot fall out.

The positioning means 4 includes locking devices 21, 21, ... that are installed at equal intervals on each wire member 2 according to the number of horizontal bars Y, and a positioning cylinder 41 that is welded to the other end of the temporary holding part body 32 of the temporary holding part 31. The positioning cylinder 41 of each temporary holding part body 32 has an insertion hole 42 that penetrates in the vertical direction so that each wire member 2 located between adjacent locking devices 21, 21 in the vertical direction of each wire member 2 can be inserted at the other end of the temporary holding part body 62. When the wire member 2 is lifted by the lifting device, the peripheral portion (periphery of the insertion hole 42) abuts against each locking device 21, thereby positioning the temporary holding part 31 so that it cannot move downward. In this case, the locking devices 21 are fixed to each wire member 2 at equal intervals (for example, 150 mm to 300 mm).

Furthermore, each positioning jig 3 is provided with a tip-prevention plate 38 fixed to the side of the positioning cylinder 41 opposite the temporary holding portion 31. This tip-prevention plate 38 holds each positioning jig 3 individually in an upright position relative to the installation surface with the opening of the temporary holding portion 31 facing the base end of the wire member 2 (the upper side when the wire member 2 is in the lifted state).

Figure 7 is a front view showing the state in which each horizontal bar Y positioned at the intersection K with each vertical bar by the horizontal bar arrangement device 1 of Figure 1 has been tied, and Figure 8 shows an enlarged view of the positioning jig 3 of the horizontal bar arrangement device 1 of Figure 7. Also, Figure 9 is a right side view of the horizontal bar arrangement device 1 of Figure 7 as seen from the right side, Figure 10 is an enlarged view of the positioning jig 3 of the horizontal bar arrangement device 1 of Figure 9, and Figure 11 is a plan view of the horizontal bar arrangement device 1 of Figure 7 as seen from above.

As shown in Figures 7 to 11, when the horizontal reinforcing bar arrangement device 1 arranges multiple horizontal reinforcing bars Y, Y, ... for four vertical reinforcing bars T, T, ... that are arranged in a straight line in the horizontal direction and extend in the vertical direction, the temporary holding parts 31 are positioned so that each horizontal reinforcing bar Y is positioned at the intersection K with each vertical reinforcing bar T by the positioning means 4 of each positioning jig 3. Each wire member 2 of the horizontal reinforcing bar arrangement device 1 is arranged between two vertical reinforcing bars T, T that are separated from each other by two of the vertical reinforcing bars T when lifted by the lifting device. At this time, each horizontal reinforcing bar Y temporarily held by each temporary holding part 31 of the horizontal reinforcing bar arrangement device 1 is positioned at the intersection K with each vertical reinforcing bar T. Note that each vertical reinforcing bar T is erected at an interval (for example, an interval of 200 to 300 mm) according to the structure to be constructed, and the vertical reinforcing bars T, T may be directly connected vertically using a mechanical joint such as a coupler depending on the height of the structure.

Each horizontal bar Y is then tied to each vertical bar T at each intersection K with the vertical bar T by wire S. Once the tying with wire S has been completed at all intersections K, K, ..., the wing bolts 33 of each positioning jig 3 are released to open the openings of the temporary holding parts 31, allowing each horizontal bar Y to be removed through the openings of the temporary holding parts 31. At this time, each horizontal bar Y temporarily held by each positioning jig 3 of the horizontal bar arrangement device 1 is positioned relative to each vertical bar T from the other end of the temporary holding part main body 32.

Figure 12 is a front view of the horizontal reinforcing bar arrangement device 1 showing the state in which the temporary holding of each horizontal bar Y by each temporary holding portion 31 of each positioning jig 3 in Figure 7 has been released, and Figure 13 shows a right side view of the horizontal reinforcing bar arrangement device 1 in Figure 12 as seen from the right side. Also, Figure 14 shows an enlarged view of the positioning jig 3 of the horizontal reinforcing bar arrangement device 1 in Figure 13. Note that, for the sake of convenience, Figures 12 and 14 show the state in which the wing bolt 33 of each positioning jig 3 has been released from its screwed state, with the wing bolt 33 fastened in the bolt insertion hole 34 on the upstream side in the insertion direction.

As shown in Figures 12 to 14, once the wing bolts 33 of each positioning jig 3 have been released, each wire member 2 lifted by the lifting device is lowered a small amount (for example, about 100 mm), and each horizontal bar Y is released from the temporary holding portion 31 of each positioning jig 3 through the opening.

Figure 15 shows a right side view of the horizontal reinforcing bar arrangement device 1 as seen from the right side in a state in which the temporary retention of the horizontal reinforcing bars Y by the temporary retention portions 31 of each positioning jig 3 in Figure 11 has been released. As shown in Figure 15, when all the horizontal reinforcing bars Y are released through the openings of the temporary retention portions 31 of each positioning jig 3, the horizontal reinforcing bar arrangement device 1 becomes movable in preparation for the temporary retention of the next horizontal reinforcing bars Y, Y, .... Note that, for the sake of convenience, Figure 15 also shows the state in which the wing bolts 33 of each positioning jig 3 have been released from their screwing in a state in which they are fastened in the bolt insertion holes 34 on the upstream side in the insertion direction.

Next, the procedure for transporting each horizontal bar Y to the site while it is temporarily held by each positioning jig 3 of the horizontal bar placement device 1 will be explained with reference to the drawings.

Figure 16 is a perspective view of the horizontal reinforcing bar arrangement device 1 in Figure 15, and Figure 17 is an enlarged view of the positioning jig 3 of the horizontal reinforcing bar arrangement device 1 in Figure 16, viewed from the right side. For convenience, Figures 16 and 17 show the wing bolts 33 fastened to the bolt insertion holes 34 on the upstream side in the insertion direction in order to easily show the state of each positioning jig 3 prepared for screwing with the wing bolts 33.

As shown in Figures 16 and 17, the wire members 2 are laid parallel to each other along the installation surface G, and each positioning jig 3 is held in an upright position with the opening of the temporary holding portion 31 facing the base end side of the wire member 2 (the right end side in Figure 17) by anti-tip plates 38 at equal intervals on the installation surface G. At this time, by tensioning each wire member 2 with each anti-tip plate 38 installed on the installation surface G, the opening of the temporary holding portion 31 of each positioning jig 3 faces the base end side of the wire member 2.

Figure 18 shows a perspective view of the horizontal reinforcing bar arrangement device 1 showing the state in which each horizontal bar Y has been inserted through the opening in the temporary holding portion 31 of each positioning jig 3 in Figure 16. Also, Figure 19 shows an enlarged view of the positioning jig 3 from the left side showing the procedure up to temporarily holding the horizontal bar Y in the temporary holding portion 31 in Figure 16, where (a) shows the state before the horizontal bar Y is inserted into the temporary holding portion 31, (b) shows the state after the horizontal bar Y has been inserted into the temporary holding portion 31, and (c) shows the state in which the horizontal bar Y is temporarily held in the temporary holding portion 31. Note that, for convenience, in Figures 18 and 19 (a) and (b), the wing bolt 33 is shown in a state of being fastened in the bolt insertion hole 34 on the upstream side in the insertion direction in order to easily show the state in which each positioning jig 3 is prepared for screwing with the wing bolt 33.

As shown in Figure 18 and Figures 19(a) and (b), horizontal bars Y, Y, ... are inserted through the temporary holding parts 31 of the positioning jigs 3 of the wire members 2 laid parallel to each other along the installation surface G, via the openings at both ends of the temporary holding part main body 32. Then, as shown in Figure 19(c), the butterfly bolt 33 inserted through the bolt insertion hole 34 on the upstream side of the insertion direction of the temporary holding part main body 32 is screwed into the bolt insertion hole 34 on the downstream side of the insertion direction to close the opening, thereby temporarily holding each horizontal bar Y in the temporary holding part 31.

Figure 20 shows a left side view of the horizontal reinforcing bar arrangement device 1, in which the horizontal bars Y are temporarily held by the temporary holding parts 31 in Figure 18, as seen from the left side during lifting. As shown in Figure 20, the wire members 2 begin to be lifted by the lifting device while being spaced apart by the support rods.

Figure 21 shows a left side view of the horizontal reinforcing bar arrangement device 1 in Figure 20 after it has been lifted and folded in half. As shown in Figure 21, each wire member 2 lifted by the lifting device is gradually lowered to the installation surface G, and approximately half of the length of each wire member 2 is folded with the assistance of a worker.

Figure 22 shows a left side view of the horizontal reinforcing bar arrangement device 1 in Figure 21 in a fully folded state. As shown in Figure 22, the remaining wire members 2 that have been folded to approximately half their length are gradually lowered to the installation surface G by a lifting device, completing the folding of the horizontal reinforcing bar arrangement device 1.

Then, the horizontal reinforcing bar arrangement device 1, which is now completely folded and compact, is placed on the bed of a truck (not shown) and transported to the construction site.

Therefore, in this embodiment, a plurality of positioning jigs 3, 3, ... that individually position each horizontal bar Y in a vertically arranged state so that it can be arranged are provided at equal intervals on each wire member 2 that extends vertically between the vertical bars T, T that are arranged horizontally and vertically in a row, and the temporary holding portions 31, 31, ... that temporarily hold each horizontal bar Y on each wire member 2 are positioned for each positioning jig 3 by the positioning means 4 so that each horizontal bar Y is positioned at the intersection K with each vertical bar T. As a result, a plurality of horizontal bars Y, Y, ... are arranged for each vertical bar T arranged horizontally while being simultaneously positioned at each intersection K, and binding can be performed at the intersections K, K, ... in one go, dramatically improving work efficiency.

In addition, wing bolts 33 are screwed between both ends of the temporary holding portion main body 32 with each horizontal bar Y inserted to close the opening, so that the horizontal bars Y, Y, ... can be easily temporarily held and released in each temporary holding portion 31 by attaching and detaching the wing bolts 33.

In addition, the butterfly bolts 33 are connected to the temporary holding part main body 32 by wire S so that they cannot fall off, so the butterfly bolts 33 will not be lost and the horizontal bars Y can be securely temporarily held by the butterfly bolts 33 at each temporary holding part 31.

Furthermore, the positioning cylinder 41 inserted into each wire member 2 is abutted against the locking devices 21, 21, ... installed at equal intervals on each wire member 2, positioning the temporary holding portion 31 so that it cannot move downward. This allows the temporary holding portion 31 to be easily positioned relative to each wire member 2 lifted by a lifting device, and the simple configuration allows each horizontal bar Y to be reliably positioned at the intersection K with each vertical bar T.

Next, a second embodiment of the present invention will be described with reference to the drawings.

In this embodiment, the configuration of each positioning jig has been changed. The configuration other than each positioning jig is the same as in the first embodiment, and the same parts are given the same reference numerals and their description is omitted.

Figure 23 is a perspective view of the positioning jig 3 of the horizontal reinforcing bar arrangement device 1 according to the second embodiment of the present invention, and Figure 24 shows a right side view of the positioning jig 3 of Figure 23 as seen from the right side. Also, Figure 25 shows a plan view of the positioning jig 3 of Figure 23 as seen from above, and Figure 26 shows a rear view of the positioning jig 3 of Figure 23 as seen from the rear side.

That is, as shown in Figures 23 to 26, each positioning jig 5 includes a temporary holding portion 51 that temporarily holds each horizontal line Y on each wire member 2, and a positioning means 4 that positions this temporary holding portion 51 so that each horizontal line Y is positioned at the intersection K with each vertical line T.

The temporary holding part 51 comprises a roughly U-shaped temporary holding part main body 52 with an opening that allows the horizontal bar Y to be inserted therethrough, and a butterfly bolt 53 as a bridging member that is hung between both ends of the temporary holding part main body 52 to close the opening. In addition, nut members 50, 50 that face each other with their axes aligned are welded to one end and the other end of the temporary holding part main body 52. The butterfly bolt 53 is screwed into both nut members 50, 50 at one end and the other end so as to close the opening of the temporary holding part main body 52 with the horizontal bar Y inserted therethrough.

In this case, the temporary holding body 52 is formed by bending a deformed steel bar cut to a predetermined length (for example, about 150 mm) into a roughly U-shape. At this time, the butterfly bolt 53 is inserted into the nut member 50 on the upstream side in the insertion direction of the nut members 50, 50 at both ends of the temporary holding body 52 while being screwed into the nut member 50 on the downstream side in the insertion direction so as to close the opening of the temporary holding body 52.

The positioning cylinder 41 of the positioning means 4 is welded to the other end of the temporary holding part main body 52, which has the nut member 50 on the downstream side in the insertion direction. At this time, the butterfly bolt 53 is screwed into the nut members 50, 50 on the upstream and downstream sides in the insertion direction, respectively, so that even if the wing bolt 53 is released from the screwing of the nut member 50 on the downstream side in the insertion direction, it cannot fall off due to the screwing of the nut member 50 on the upstream side in the insertion direction.

In this embodiment, the wing bolts 53 are threadedly fastened to and span the nut members 50, 50 at one and the other ends of the temporary holding portion main body 52 with each horizontal bar Y inserted therethrough, so that the wing bolts 53 can be easily attached and detached to temporarily hold and release the horizontal bars Y, Y, ... at each temporary holding portion 51.

Next, the third embodiment of the present invention will be described with reference to the drawings.

In this embodiment, the configuration of each positioning jig has been changed. The configuration other than each positioning jig is the same as in the first embodiment, and the same parts are given the same reference numerals and their description is omitted.

Figure 27 is a perspective view of a positioning jig for a horizontal reinforcing bar arrangement device 1 according to a third embodiment of the present invention, and Figure 28 shows a right side view of the positioning jig in Figure 27 as seen from the right side. Also, Figure 29 shows a plan view of the positioning jig in Figure 27 as seen from above, and Figure 30 shows a rear view of the positioning jig in Figure 27 as seen from the rear side.

That is, as shown in Figures 27 to 30, each positioning jig 6 has a temporary holding portion 61 that temporarily holds each horizontal line Y on each wire member 2, and a positioning means 7 that positions this temporary holding portion 61 so that each horizontal line Y is located at the intersection K with each vertical line T.

The temporary holding part 61 is provided with a roughly U-shaped temporary holding part main body 62 with an opening that allows the end of the horizontal bar Y to be inserted therethrough, a bolt member 64 screwed into a screw hole 63 recessed in one end of the temporary holding part main body 62, a hanging member 66 whose one longitudinal end is supported rotatably around the axis of the bolt member 64 and whose other longitudinal end is engaged with a recess 65 provided in the other end of the temporary holding part main body 62 so as to close the opening of the temporary holding part main body 62, and a screw member 68 screwed into a screw hole 67 provided in the middle of the longitudinal direction of the hanging member 66 and tightened until it abuts against the horizontal bar Y inserted into the temporary holding part main body 62. The center of a rod material 69 extending horizontally is welded to the head of the screw member 68, so that the screw member 68 can be easily tightened and loosened by the rod material 69.

The bolt member 64 also includes a threaded portion 641 that is screwed into the threaded hole 63 over approximately two-thirds of its axial length, and a cylindrical portion 642 that protrudes from the threaded hole 63 over the remaining one-third of its axial length and is rotatably inserted into an insertion hole 661 at one longitudinal end of the hanging member 66. In this case, the hanging member 66 is formed by cutting a plate material with a laser.

The positioning means 7 includes a locking device 21 and an insertion hole 71 that penetrates vertically so that the wire member 2 can be inserted into the other end (the left end in Figs. 31 and 32) of the temporary holding part main body 62 of the temporary holding part 61. When the wire member 2 is lifted by the lifting device, the peripheral portion (periphery of the insertion hole 71) of the insertion hole 71 abuts against each locking device 21, thereby positioning the temporary holding part 61 so that it cannot move downward. The wire member 2 located between the locking devices 21, 21 adjacent to each other in the vertical direction is inserted into the insertion hole 71 of each temporary holding part main body 62.

In this embodiment, the hanging member 66 is rotated around the axis of the bolt member 64 to close the openings at one and the other ends of the temporary holding part main body 62 with each horizontal bar Y inserted therethrough, and the other longitudinal end is engaged with the recess 65 at the other end of the temporary holding part main body 62. Then, the screw member 68 is tightened by the rod member 69 to press the tip of the screw member 68 against the horizontal bar Y in the temporary holding part main body 62, making the hanging member 66 non-rotatable, thereby temporarily holding the horizontal bar Y. As a result, the hanging member 66 can be made non-rotatable or rotatable by tightening or loosening the screw member 68, and the horizontal bars Y, Y, ... can be easily temporarily held and released at each temporary holding part 61.

The present invention is not limited to the above-described embodiments, but includes various other modified examples. For example, in the above-described embodiments, two wire members 2, 2 are supported at a distance on the support rod and lifted by a lifting device, but a support rod on which three or more wire members are supported at a distance may be lifted by a lifting device. In this case, the support rod may be set to be longer than the length between the temporary holding points at both ends of each cross bar that is temporarily held by three or more positioning jigs.

In addition, in each of the above-described embodiments, the wire members 2 are arranged between the vertical muscles T, T that are spaced apart by two bars among the vertical muscles T arranged in the horizontal direction, but the wire members may be arranged between the vertical muscles that are spaced apart by one bar or three or more bars among the vertical muscles.

In addition, in each of the above-described embodiments, when transporting to the site while each horizontal bar Y is temporarily held by each positioning jig 3 of the horizontal bar arrangement device 1, each wire member 2 lifted by a lifting device is gradually lowered to the installation surface G while being folded and placed on the bed of a truck for transport to the construction site. However, at the construction site, each wire member of the horizontal bar arrangement device may be gradually lifted from its lowest position by a lifting device, and the horizontal bars may be temporarily held by each positioning jig 3 of each wire member each time. In that case, the lifting device prepared only at the construction site can simultaneously temporarily hold each horizontal bar and arrange the reinforcement for each vertical pipe, which is extremely advantageous in implementation.

In addition, in each of the above embodiments, the wire member 2 is used as the support member, but multiple support members such as chain members may be used, and this chain member can also perform temporary holding of each horizontal bar and reinforcement for each vertical pipe with a work procedure that is almost comparable to that of each wire member. On the other hand, if temporary holding of each horizontal bar and reinforcement for each vertical pipe are performed only at the construction site using a lifting device, multiple rod-shaped steel materials may be used as support members, and each steel material may be laid on the installation surface at the construction site, and one end (upper end) of each steel material may be lifted by a lifting device while the horizontal bars are temporarily held by each positioning jig for each steel material, and temporary holding of each horizontal bar and reinforcement for each vertical pipe may be performed.

In addition, in each of the above-described embodiments, each horizontal bar Y temporarily held by each positioning jig 3 of the horizontal bar arrangement device 1 is positioned relative to each vertical bar T from the other end side of the temporary holding unit main body 32, but each horizontal bar temporarily held by each positioning jig of the horizontal bar arrangement device may be positioned relative to each vertical bar from one end side of the temporary holding unit main body.

In addition, in each of the above embodiments, a D32 deformed steel bar is used for each vertical bar T and each horizontal bar Y, but the outer diameter is not limited to this, and deformed steel bars with a smaller or larger diameter may be used for each vertical bar and each horizontal bar, respectively. In that case, the temporary holding portion body needs to be changed to a size that can accommodate the maximum outer diameter of the deformed steel bar.

In addition, in each of the above embodiments, each horizontal bar Y is positioned relative to the vertical bars T, T, ... arranged in a straight line in the horizontal direction, but the horizontal bar arrangement device may position the horizontal bars relative to the vertical bars arranged in a curved horizontal direction. In that case, it is necessary to use curved horizontal bars and support rods so that they are positioned relative to each vertical bar that curves in the horizontal direction.

Furthermore, in the third embodiment, the plate material is cut by a laser to form the bridging member 66, but as shown in Figures 31 and 32, the positioning jig 8 may be formed by casting. The positioning jig 8 includes a temporary holding portion 81 that temporarily holds each horizontal bar Y to each wire member 2, and a positioning means 7. The temporary holding part 81 includes a roughly U-shaped temporary holding part main body 82 with an opening that allows the end of the horizontal bar Y to be inserted therethrough, a bolt member 64 screwed into a screw hole 63 recessed in one end of the temporary holding part main body 82, a hanging member 86 whose one longitudinal end is supported rotatably around the axis of the bolt member 64 and whose other longitudinal end is engaged with a recess 65 provided in the other end of the temporary holding part main body 82 so as to close the opening of the temporary holding part main body 82, and a screw member 68 screwed into a screw hole 67 provided in the middle of the longitudinal direction of the hanging member 86 and tightened until it abuts against the horizontal bar Y inserted into the temporary holding part main body 82. In this case, it is also possible to form a slim-shaped temporary holding part 81 by removing unnecessary parts that cannot be cut by laser, which is very advantageous in reducing material costs.

Next, the fourth embodiment of the present invention will be described with reference to the drawings.

In this embodiment, the configuration of each positioning jig has been changed. The configuration other than each positioning jig is the same as in the first embodiment, and the same parts are given the same reference numerals and their description is omitted.

Also, Figure 36 is a right side view of the temporary holding body of the positioning jig of Figure 33 seen from the right side, and Figure 37 is a rear view of the temporary holding part body of Figure 36 seen from the rear side. Furthermore, Figure 38 is a rear view of the positioning member of the positioning jig of Figure 33 seen from the rear side, and Figure 39 is an exploded perspective view of the positioning jig of Figure 33.

That is, as shown in Figures 33 to 39, each positioning jig 90 includes a temporary holding portion 91 that temporarily holds each horizontal line Y on each wire member 2, and a positioning means 92 that positions this temporary holding portion 91 so that each horizontal line Y is positioned at the intersection K with each vertical line T.

The temporary holding portion 91 has a roughly U-shaped temporary holding portion main body 911 with an opening that allows the horizontal stripe Y to pass through. One side piece 912 on one end side (the left side in FIG. 35) of this temporary holding portion main body 911 is formed in a roughly rectangular flat plate shape. In addition, the center in the left-right direction of the temporary holding portion main body 911 has a recess 913 that is recessed inward toward the side opposite the wire member 2 and has a roughly arc-shaped cross section.

The positioning means 92 includes a substantially rectangular flat positioning member 921 that faces one side piece 912 of the temporary holding part main body 911 with the wire member 2 sandwiched between them. A recess 922 that is recessed in a substantially arc-shaped cross section toward one side of the temporary holding part main body 911, which is the side opposite the wire member 2, is also provided in the center of the left-right direction of the positioning member 921. The one side piece 912 of the temporary holding part main body 911 and the positioning member 921 face each other in a sandwiched state with the wire member 2 positioned in each of the recesses 913, 922. Furthermore, the one side piece 912 of the temporary holding part main body 911 and the recesses 913, 922 of the positioning member 921 are provided with a plurality of protrusions 923 (only the recesses 922 of the positioning member 921 are shown) that protrude at equal intervals toward the wire member 2 side when the wire member 2 is sandwiched between the recesses 913, 922.

The positioning means 92 also includes screwing means 93 for screwing the temporary holding body 911 to the wire member 2 at equal intervals via the positioning member 921. The screwing means 93 includes stud bolts 931, 931, ... protruding from the four corners of one side piece 912 of the temporary holding body 911 toward the positioning member 921, bolt insertion holes 932, 932, ... that are opened at the four corners of the positioning member 921 and through which the stud bolts 931 are inserted while facing the one side piece 912 of the temporary holding body 911 with the wire member 2 sandwiched between them, and nuts 933, 933, ... that are screwed onto the tips of the stud bolts 931 that are inserted and exposed through the bolt insertion holes 932.

Furthermore, the temporary holding part 91 is provided with a hanging member 94 that is hung from one side end of the temporary holding part main body 911 to the other side end so as to close the opening of the temporary holding part main body 911. This hanging member 94 has a pair of left and right legs 941, 941 formed in a generally hairpin shape, and the base ends of both legs 941, 941 are connected to a winding part 942 that is wound once, and biases both legs 941, 941 in a direction to open outward in the left and right direction. The winding part 942 of the hanging member 94 is attached to the positioning member 921 via a string-like member 943, preventing the hanging member 94 from disappearing.

A pair of long holes 924, 924 that are long in the left-right direction are provided at approximately the center in the up-down direction of the positioning member 921. Furthermore, a pair of long holes 914, 914 that are long in the left-right direction are provided at approximately the center in the up-down direction of one side piece 912 of the temporary holding part main body 911, while a pair of long holes 915, 915 that are long in the left-right direction are provided at approximately the center in the up-down direction of the other side end side facing the one side piece 912.

As shown by the imaginary line (two-dot chain line) in FIG. 39, the legs 941, 941 of the hanging member 94 are deformed by hand against the biasing force toward the closing side, and are inserted from the long holes 924 of the positioning member 921 into the long holes 914 and the long holes 915 on the other side end side of the temporary holding part main body 911, and the deformation by hand is released, so that the hanging member 94 engaged with the rear edge of each long hole 915 is released by removing the legs 941, 941 from the long holes 924 of the positioning member 921 via the long holes 915 on the other side end side of the temporary holding part main body 911 and the long holes 914 on the one side end side of the temporary holding part main body 911, and the long holes 912 on the other side end side of the temporary holding part main body 911.

In this embodiment, the legs 941, 941 of the hanging member 94, which have been deformed by hand to the closing side against the biasing force, are inserted from the long holes 924 of the positioning member 921 into the long holes 914 and the long holes 915 on the other side end of the one side piece 912 of the temporary holding part main body 911, and the deformation by hand is released and the legs are engaged with the rear edge of each long hole 915, thereby temporarily holding the horizontal stripes Y. As a result, by inserting and releasing the legs 941, 941 from the long holes 924 of the positioning member 921 into and from the long holes 914 and the long holes 915 on the other side end of the one side piece 912 of the temporary holding part main body 911 while being deformed by hand to the closing side against the biasing force, the horizontal stripes Y, Y, ... can be easily temporarily held and temporarily released by each temporary holding part 91.

Next, the fifth embodiment of the present invention will be described with reference to the drawings.

In addition, between the left and right insertion holes 975, 975 of the upper and lower pieces 971, 972, there is provided a substantially U-shaped cutout hole 976 that opens to the other side (the right side in FIG. 41).

Furthermore, the vertical piece 973 of the positioning member 974 is provided with four round holes 977, 977, ... that open at positions corresponding to the four corners of the approximately square shape slightly to one side in the left-right direction (the right side in FIG. 45). Furthermore, the vertical piece 973 of the positioning member 974 is provided with a vertically long hole 978 that opens at the other end in the left-right direction (the left end in FIG. 45).

The temporary holding portion main body 961 has male screws 962, 962 at both ends inserted from below into the insertion holes 975, 975, ... of the upper and lower pieces 971, 972 of the positioning member 974, and is fastened to the male screws 962, 962 at both ends located above and below the upper piece 971 of the positioning member 974 by upper and lower nuts 979, 979 that are screwed in so as to sandwich the upper piece 971 from both above and below.

Furthermore, the positioning means 97 includes a screwing means 98 that screws the temporary holding portion main body 961 to the wire member 2 at equal intervals via a positioning member 974. The screwing means 98 includes a pair of upper and lower U-bolts 982, 982 that are substantially U-shaped and have male screws 981, 981 at both ends. The wire member 2 is inserted through the notched holes 976, 976 in the upper and lower pieces 971, 972 of the positioning member 974, and the male screws 981, 981 at both ends of the U-bolts 982, 982 are inserted through the left and right round holes 977, 977 of the vertical piece 973 with the wire member 2 contained inside from the other side, and the vertical piece 973 is fastened by nuts 984, 984 from the back side (left side in FIG. 41 ).

The temporary holding part 97 also includes a long bolt member 963 that serves as a bridging member that is bridged from one end of the temporary holding part main body 961 to the other end so as to close the opening of the temporary holding part main body 961. This bolt member 963 is inserted from the other side into a long hole 978 in a vertical piece 973 of a positioning member 974, and a nut 964 is screwed onto a male screw (not shown) at the tip to prevent it from falling out of the long hole 978.

As shown in Figures 40, 41 and 49, the head 965 of the bolt member 963 is inserted into the left-right extension 960 at the center of the temporary holding part main body 961 from above the left-right extension Y with the temporary holding part main body 961 inserted through the left-right extension Y and locked in place. On the other hand, the bolt member 963 with the head 965 locked in the left-right extension 960 at the center of the temporary holding part main body 961 is released from the head 965 by removing it from the left-right extension 960 at the center of the temporary holding part main body 961 and moving it to one side edge of the long hole 978 in the vertical piece 973 of the positioning member 974.

In this embodiment, the head 965 of the bolt member 963 inserted into the long hole 978 of the vertical piece 973 of the positioning member 974 is inserted into the left-right extension 960 at the center of the temporary holding part main body 961 from above the horizontal line Y while the horizontal line Y is inserted into the temporary holding part main body 961, and is engaged to temporarily hold the horizontal line Y. As a result, by inserting and removing the head 965 of the bolt member 963 from above the horizontal line Y of the temporary holding part main body 961 into and from the left-right extension 960 at the center of the temporary holding part main body 961, the horizontal lines Y, Y, ... can be easily temporarily held and released by each temporary holding part 96.
