[0012]
When the reinforcing bar clip 3 is attached to the setup bar 2, the first reinforcing bar fitting part 5 is attached by being fitted to the outer periphery of the setup bar 2. Next, a plurality of set-up bars 2 to which the reinforcing bar clips 3 are attached are arranged in parallel and in a plane on an interval. And the position of each row | line | column of the reinforcing bar clip 3 with which it attached to each setup reinforcement 2 and was located in a line in the direction orthogonal to the setup reinforcement 2 is aligned with the position of the main reinforcement 1 of each row | line | column, By inserting the main reinforcing bar 1 into the second reinforcing bar fitting portion 6 of the reinforcing bar clip 3, the main reinforcing bar 1 is held in a plane via the set-up bars 2 and the reinforcing bar clip 3, thereby obtaining the reinforcing bar unit T.
[0013]
Next, an assembling apparatus for carrying out this assembling method will be described with reference to FIG. 3 is a perspective view of a part of the assembling apparatus 10 as seen from above, FIG. 4 is a front view as seen from the direction of arrow IV in FIG. 3, FIG. 5 is a sectional view as seen from arrow V in FIG. It is VI arrow sectional drawing.
[0014]
As shown in FIG. 3 and FIG. 4, on the reinforcing bar 11 of the assembling apparatus 10, as shown in FIG. 3 and FIG. 4, a main reinforcing bar base 12 having receiving grooves 15 for holding the main reinforcing bar 1 at a predetermined pitch, A main reinforcing bar receiving bar 13 is provided that is moved up and down by a hydraulic cylinder 16) and dropped into the groove 15 by receiving the main reinforcing bar 1. A plurality of main reinforcing bar receiving bases 12 and main reinforcing bar receiving bars 13 are alternately arranged at appropriate intervals. The main reinforcing bar receiving base 12 is made of a steel material having a U-shaped cross section, and receiving grooves 15 are formed at a predetermined pitch at the upper end edge thereof. As shown in FIG. 5, the main reinforcing bar receiving bar 13 is supported by a link mechanism 17 so as to move up and down along a certain trajectory, and the main reinforcing bar is rolled on the receiving bar 13 in the raised state, and the V groove portion 14 at the upper edge of the receiving bar 13. The main reinforcing bar 1 can be dropped into the receiving groove 15 of the main reinforcing bar receiving base 12 by lowering the receiving bar 13.
[0015]
The steel material having a U-shaped cross section constituting the main reinforcing bar receiving base 12 is pre-mounted on the setting bar 2 by pushing and moving the setting bar 2 set in the direction perpendicular to the main reinforcing bar 1 in the longitudinal direction. A push-in mechanism 19 is provided for fitting the reinforcing bar clip 3 on the outer periphery of the main reinforcing bar 1. The pushing mechanism 19 includes a pushing bar 20 disposed along the longitudinal direction of the set-up bar 2, and a driving device (air cylinder or hydraulic pressure) that pushes and moves the pushing bar 20 in the longitudinal direction as shown in FIG. Cylinder) 22). And the clip press rib 21 for pressing each rebar clip 3 directly and making it fit in the outer periphery of the main rebar 1 is provided in the upper surface of the pushing rod 20. FIG. As shown in FIG. 3, a bracket 26 having a receiving groove portion 25 of the set-up bar 2 is provided in a steel material having a U-shaped cross section constituting the main reinforcing bar base 12.
[0016]
Next, a procedure for assembling a reinforcing bar unit using the above assembling apparatus will be described mainly with reference to FIG.
First, in a state where the main reinforcing bar receiving bar 13 is raised, the main reinforcing bar 1 is rolled on the main reinforcing bar 1 and the main reinforcing bar 1 is set in the V groove portion 14. Next, the main reinforcing bar receiving bar 13 is lowered, and the main reinforcing bar 1 is dropped into the receiving groove 15 of the main reinforcing bar receiving base 12. Thereby, the main rebar 1 is held at a predetermined pitch.
[0017]
Next, the set-up bars 2 to which the reinforcing bar clips 3 are attached in advance at a predetermined pitch are arranged on the steel material constituting the main reinforcing bar receiving base 12 and are fitted into the receiving groove portions 25 of the bracket 26. Under the present circumstances, it sets so that the entrance of the 2nd reinforcing bar fitting part 6 of the reinforcing bar clip 3 may be located in the pushing side with respect to the main reinforcing bar 1. By doing so, the reinforcing bar clips 3 are arranged in a line and placed on the main reinforcing bar 1.
[0018]
Next, the drive devices 22 of all the pushing mechanisms 19 are operated at the same time to slide the setup bars 2 in the pushing direction. Then, the second reinforcing bar fitting portion 6 of each reinforcing bar clip 3 is fitted into the outer periphery of the main reinforcing bar 1, thereby completing the reinforcing bar unit T (see FIG. 1) having a structure in which the main reinforcing bar 1 is held by the setup bar 2. To do. After completion, the reinforcing bar unit T may be removed from the assembling apparatus 10 using a lifting machine.
[0019]
【The invention's effect】
As described above, according to the assembling apparatus of the present invention, the reinforcing bar clip is attached to the secondary reinforcing bar in advance, and the secondary reinforcing bar and the main reinforcing bar are arranged in an orthogonal relationship, and then the reinforcing bar clip is fitted into the main reinforcing bar. As a result, an assembly method for completing the reinforcing bar unit can be performed, so that the work can be performed more easily and the construction efficiency can be increased and the cost can be reduced as compared with the case of connecting using welding or annealed iron wire. In addition, since the main reinforcing bar and the secondary reinforcing bar are connected by the reinforcing bar clip, there is no fear of strength deterioration and displacement, and the quality can be improved.
[0020]
Further, according to the assembling apparatus of the present invention, the main reinforcing bars are arranged on the reinforcing bar in a relationship orthogonal to the auxiliary reinforcing bars, and the reinforcing bar clip previously attached to the auxiliary reinforcing bars is used only by operating the pushing device. Since the main reinforcing bar and the secondary reinforcing bar can be connected, the above assembling method can be easily implemented. In particular, when the reinforcing bar clip is directly pressed by the clip pressing portion, the reinforcing bar clip can be securely fitted into the main reinforcing bar with a small force. Further, when the main reinforcing bar placed on the receiving bar is dropped into the receiving groove on the main reinforcing bar receiving base by the lifting mechanism, the main reinforcing bar can be set more easily.
