In the stopper 64, the upper side 72 constitutes a first stopper surface and the side 76 constitutes a second stopper surface because the cross section is a quadrangle.

(Action and effect)
The operation and effects of mounting and supporting the cross bar 14 on the reinforcing bar support structure 10, the reinforcing bar support module 16 and the reinforcing bar support jig 12 of the present invention will be described below. Description will be made in chronological order unless otherwise specified. Further, after one operation is performed in a plurality of reinforcing bar support structures 10 (for example, three reinforcing bar support structures 10 shown in FIG. 1A), the next operation is performed.

  As shown in FIGS. 4 (a) and 6 (a), in the open state in which the upper portion of the reinforcing bar gripping portion 46 is opened, the cross bar 14 is placed on the reinforcing bar gripping portion 46 and gripped. At this time, the butterfly screw 62 is fastened to the leg 53 of the bolt 50 and the reinforcing bar restricting member 56, and the reinforcing bar restricting member 56 is fixed to the main body 44. Further, the contact surface 74 (shown in FIG. 6A) of the reinforcing bar restricting member 56 is in contact with the side 76 of the stopper 64, and the reinforcing bar restricting member 56 is engaged with the stopper 64. Then, the reinforcing bar 14 is fitted into the reinforcing bar gripping portion 46.

  The butterfly screw 62 is turned counterclockwise, and the butterfly screw 62 is loosened with respect to the leg 53 of the bolt 50 and is separated from the reinforcing bar restricting member 56 (in the negative direction shown in FIG. 2A). And the reinforcing bar restricting member 56 is in a rotatable state. At this time, a reaction force is applied to the contact surface 74 of the reinforcing bar restricting member 56 from the side 76 of the stopper 64. Therefore, even if the reinforcing bar restricting member 56 is not held and fixed by a tool or the like in order to loosen the butterfly screw 62, the reinforcing bar restricting member 56 does not rotate counterclockwise together with the butterfly screw 62.

The reinforcing bar restricting member 56 is rotated clockwise as shown in FIGS. 4 (b) and 6 (b). The reinforcing bar restricting member 56 is moved along the engagement groove 54 obliquely upward as shown in FIGS. 5 (a) and 7 (a). The reinforcing bar restricting member 56 is rotated clockwise as shown in FIGS. 5B and 7B, and is positioned above the reinforcing bar gripping portion 46.

  The reinforcing bar restricting member 56 is moved downward (in the Z-axis negative direction) along the restricting groove 60, engaged with the stopper 64 and stopped, and as shown in FIGS. 1 (a) and 2, The restriction member 56 is in a state of covering the upper portion of the cross bar 14 placed on the reinforcing bar holding portion 46. At this time, the leg portion 53 of the bolt 50 is fitted into the restriction groove 60, and the restriction groove 60 is engaged with the leg portion 53 of the bolt 50. The butterfly screw 62 is turned clockwise, and the butterfly screw 62 is tightened against the leg 53 of the bolt 50 to press the reinforcing bar restricting member 56. The reinforcing bar restricting member 56 is fixed to the main body 44 in a state in which the main body 44 is held by the head portion 51 (shown in FIG. 2B) of the bolt 50 and the reinforcing bar restricting member 56. As a result, a release restriction state in which the horizontal bars 14 are separated from the rebar holding portion 46 is set. When the butterfly screw 62 is turned clockwise, a reaction force is applied from the upper side 72 of the stopper 64 to the contact surface 74 of the reinforcing bar restricting member 56. Therefore, even if the reinforcing bar restricting member 56 is not held and fixed by a tool or the like in order to turn the butterfly screw 62, the reinforcing bar restricting member 56 does not rotate clockwise together with the butterfly screw 62.

As described above, when the stopper 64 loosens the butterfly screw 62 and places the cross bar 14 on the rebar holding portion 46 (in the state shown in FIGS. 4A and 6A), and the butterfly screw 62 When tightening and fixing the reinforcing bar restricting member 56 to the main body portion 44 (in the state shown in FIG. 1A), the rotation of the reinforcing bar restricting member 56 can be prevented. Further, the stopper 64 moves the reinforcing bar restricting member 56 downward (in the negative direction of the Z-axis) along the restricting groove 60 (from the state shown in FIGS. 5B and 7B to FIG. 1A) When moving to the state shown), the reinforcing bar restricting member 56 can be stopped. For this reason, one stopper 64 functions as a member for stopping the reinforcing bar restricting member 56 three times, and the entire reinforcing bar support structure 10 can be made compact.

  After the horizontal bars 14 are attached to the plurality of reinforcing bar support structures 10 as described above, the horizontal bars 14 are attached to the next plurality of reinforcing bar support structures 10, and each of the plurality of reinforcing bar support structures 10 Attachment of the horizontal bars 14 is performed. The work where attachment of the horizontal bars 14 is performed by a plurality of reinforcing bar support structures 10 uses a crane, and the reinforcing bar support jigs 12 are shown in FIG. 3 and FIG. It is carried out while lifting by When the attachment of all the cross bars 14 to the rebar support jig 12 is completed, the cross bars 14 and the rebar support jig 12 and the like are carried into the construction site in the state shown in FIG.

  According to the reinforcing bar support structure 10 according to the embodiment of the present invention, the engagement groove 54 is the reinforcing bar restricting member 56 in the release restricting state (state shown in FIG. 2) which restricts the horizontal bars 14 from being separated from the reinforcing bar gripping portion 46. The stopper 64 can restrict the rotation of the reinforcing bar restricting member 56 with respect to the reinforcing bar holding portion 46 while restricting the movement of the reinforcing bar holding portion 46 with respect to the bar. For this reason, even if the butterfly screw 62 is loosened by vibration, the reinforcing bar restricting member 56 does not move or rotate with respect to the reinforcing bar gripping portion 46, and the release restriction state is not released. Thereby, the lateral bars 14 can be more reliably prevented from falling from the reinforcing bar support structure 10 to further enhance the safety.

  As mentioned above, although one embodiment of the present invention was described, the present invention is not limited to the above-mentioned embodiment. For example, the reinforcing bar support structure 100 shown in FIG. 9 and a reinforcing bar support module including the reinforcing bar support structure 100 and a reinforcing bar support jig may be used. The reinforcing bar support structure 100 includes a main body 44, a reinforcing bar grip 46, a bolt (base shaft) 50, a reinforcing bar restricting member 56, and a stopper 64, as in the case of the reinforcing bar support structure 10 described above. The reinforcing bar support structure 100 is engaged with an engaging hole 210 provided in the main body 44 and an engaging hole 110 provided in the reinforcing bar restricting member 56 as an alternative to the butterfly screw (fixing means) 62 of the reinforcing bar support structure 10 Engaging pin 102 (fixing means).

The engaging pin 102 is called a flap pin and is commercially available, and has a cylindrical pin body 104 and a pivoting pawl 108 pivotable about a pivoting axis 106 with respect to the pin body 104. Prepare. The pin body 104 is provided with a groove 112 at its tip, as shown in FIG. 9 (a). The pivoting pawl 108 is provided in the groove 112, and is configured to be capable of pivoting around the pivoting shaft 106 in the groove 112 as shown in FIG. 9 (b). In order to allow the engagement pin 102 to penetrate, the main body 44 is provided with an engagement hole 210, and the reinforcing bar restricting member 56 is provided with an engagement hole 110. The length of the pivoting claw 108 is longer than the length of the engagement hole 210 and the engagement hole 110. The engagement pin 102 passes through the engagement hole 210 and the engagement hole 110 (Y in FIG. 9B) in a state where the rotation claw 108 is parallel to the pin body 104 (indicated by a broken line in FIG. 9B). Then, the pivoting pawl 108 is pivoted within the groove 112 about the pivoting shaft 106 in a direction perpendicular to the pin body 104 (shown by a solid line in FIG. 9B). It can be turned. At this time, due to the frictional force between the rotation claw 108 and the groove 112, the state of the rotation claw 108 in the direction perpendicular to the pin main body 104 is maintained. Since the length of the rotation claw 108 is longer than the diameters of the engagement hole 210 and the engagement hole 110, the pin body 104 never comes off from the engagement hole 110, and the engagement pin 102 becomes the main body 44 and the reinforcing bar restriction member The state engaged with 56 is maintained. Thereby, the reinforcing bar restricting member 56 is fixed to the main body 44 so that the reinforcing bar restricting member 56 does not rotate around the leg 53 of the bolt 50. In the vicinity of one end of the pin body 104, a wire hole 116 to which one end of the wire 114 is connected is provided. By connecting the other end of the wire 114 to the head 51 of the bolt 50, the engagement pin 102 can be prevented from falling. The nut 118 shown in FIG. 9B does not contact the reinforcing bar restricting member 56, and the reinforcing bar restricting member 56 is not fixed to the main body 44 by the nut 118.

In the rebar support structure 100, even if the engagement pin 102 is separated from the main body 44 by vibration, the engagement groove 54 regulates the movement of the rebar regulating member 56 relative to the rebar gripping portion 46, and the stopper 64 prevents the rebar regulating member 56. It is possible to regulate the rotation of the rebar holding portion 46 with respect to the Therefore, the reinforcing bar restricting member 56 does not move or rotate with respect to the reinforcing bar gripping portion 46, the release restricting state is not released, and the cross bars 14 do not fall from the reinforcing bar support structure 10.

  Although the embodiments of the present invention have been described above based on the drawings, the present invention is not limited to the embodiments described in the drawings, and various design changes can be made within the scope of the matters described in the claims. It is possible. For example, the direction of the restriction groove 60 is not limited to the direction parallel to the longitudinal direction of the main body 44 in the restricted state of the cross bar 14, and may be oblique to the longitudinal direction of the main body 44.
