However, in the case of the prior art, there is a problem in the movement of the products between the respective steps of reinforcing bar arrangement, bundling of the reinforcing bars, and the production of the reinforcing bar cage. It was one of the factors that led to the high cost of reinforced cage production.

[0004] Therefore, the present invention provides a smooth and especially manual movement of products between each step of reinforcing bar arrangement, bundling, reinforced cage production, and storage of the produced reinforced cage in a storage cart. It is an object of the present invention to provide a method of manufacturing a reinforcing bar cage which can be performed without requiring a reinforcing bar and which can manufacture a reinforcing bar cage efficiently and inexpensively.

[0005]

According to the present invention, a rail is laid along the side wall of a caisson to be constructed, and a reinforcing bar reinforcing process, a reinforcing bar binding process, a reinforcing bar manufacturing process, In a method of manufacturing a reinforcing bar for performing a reinforcing bar erection / storage process, a reinforcing bar arranging machine arranges a longitudinal bar and a horizontal bar on a reinforcing bar assembling truck running on the rail, and arranges the reinforcing bar. The reticulated rebar assembling cart is moved to a reticulation binding process, reticulated by a reticulation device, and the reticulated reticulation is gripped by the reticulation device of the reconnection device. The reinforced basket assembly cart is transferred from the trolley to the trolley basket assembly cart traveling on the rail, and the reinforced basket assembly cart is moved to the reinforced cage manufacturing process. The above-described reinforcing cage assembly assembled into a reinforcing cage by stirrup reinforcement by expanding The carriage then moves to the rebar KagokenOkoshi & Shelves stroke fixed by KenOkoshi reaction force receiving mechanism, housed in rebar basket storage truck undergoing construction rebar cage by KenOkoshi device.

[0006] The movement of the products during the rebar arrangement process, the rebar binding process, the rebar cage production process, and the rebar cage construction / storage process is performed by a bogie that runs on the same rail. Movement is efficiently performed without any particular need.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a work process of caisson construction work in which a method of manufacturing a reinforcing cage according to the present invention is suitably employed.

[0008] Dozens of rebar materials T transported by the truck 1 are carried in a bundled state, and are temporarily placed in a ground storage with the bundle of the rebars.

The operator selects the reinforcing bar T from the bundled reinforcing bars temporarily placed, and arranges the reinforcing bar T in the reinforcing bar reinforcing step 2. In the reinforcing bar arrangement process 2, the rebar T is gripped by the handling device of the rebar arrangement machine 3 traveling on the rail R-1, and the gripped rebar T is lifted in the height direction (Z direction). (X, Y directions) to reinforce the reinforcing bars on the rebar assembling / transporting vehicle 4 traveling on the rail R-2 laid inside the rail R-1. The rebar assembly / transportation trolley 4 having completed the rebar arrangement is moved to the rebar binding process 5 and bound by the automatic binding machine 6.

[0010] The rebar T-1 having been bound is transferred from the rebar assembling / transportation truck 4 to the rebar cage assembling / transportation cart 8, and is moved to the rebar cage production process 7, where the reticulated rebar T-1 is bound. The extension hanging rod 9 is interposed therebetween, the jack of the extension hanging rod 9 is expanded, and the reinforced basket T-2 is assembled by the stapling bar.

The rebar cage assembling / transporting cart 8 assembled with the rebar cage T-2 is moved to a rebar basket building and erecting step 10, and the cart 8 is fixed by an erecting reaction force receiving mechanism 11. Basket T
-2 is erected and stored in the reinforced basket storage cart 13.

The reinforced cage T-2 is lifted and built by the cranes 13 using the rods of the extended hanging rods 9.

The caisson structure is a rectangular caisson K. As for the side wall formwork, the outer formwork 15 and the inner formwork 16 are also integrated, and after the concrete is cast and trained, the temporary equipment is moved to the formwork apparatus 17 by the formwork elevating device 17. Lift up with the top mounted.

In concrete placement, concrete is mechanically distributed and supplied by a concrete distributor, and the level of the entire discharge port is shifted according to the concrete placement situation. Opening / closing canopy device 1 during the construction period
Rain training by 8

FIG. 2 shows the details of the automatic tying machine 6 and the rail R of the rebar assembly truck 4 so that the rebar assembly truck 4 can pass therethrough.
Column members 61 that can extend and contract across the -2 are erected on the left and right, a beam member 62 is stretched between the left and right columns 61, and a plurality of automatic tying tools 63 are supported. Is moved right and left by the hydraulic cylinder 64. The automatic binding machine 6 binds the reinforcing bars arranged on the reinforcing bar assembly cart 4. Further, the automatic binding machine 6 is provided with a rebar gripping device 65 for lifting the rebar when transferring the reticulated rebar T-1 from the rebar assembling trolley 4 to the rebar basket assembling trolley 8.

In FIG. 2, the rebar assembling trolley 4 has a reduction gear 44 and a roller 4 on a trolley 41 by a motor 43.
5, a turntable 42 is provided, which turns through the turntable 5.
6 are arranged on the reticulation at intervals specified by the defining tool 46.

FIGS. 3 to 5 show details of the reinforced basket assembling trolley 8. The traveling trolley 81 has a raised frame 83 which is raised and lowered to a vertical position and a horizontal position shown in FIG. Is supported by a shaft 84, and the reinforcing bar cage T-
When the storage frame 2 is stored in the reinforced basket storage trolley 13, the elevating cylinder 82 is operated to raise the erected frame 83 from the horizontal position to the vertical position.

An extended suspension rod indicated by 9 is interposed between the two reticulated reinforcing bars T-1 to assemble the reinforcing bar T-2. The extended hanging rod 9 has three connecting rods 92 connected at one end by hanging rods 91. Each connecting rod 92 is provided with three pressure receiving plates 94 that are opened and closed by opening and closing cylinders 93 at intervals. I have.

When assembling the reinforcing bar cage, one end of the extended hanging rod 9 is fixed to the standing frame 83 by the connecting tool 95, and the opening / closing cylinder 93 is operated to expand the pressure receiving plate 94 so as to expand the upper mesh bar T-1. And the two reticulated muscles T-1 are bound by a stapling bar and assembled into a reinforcing bar cage T-2. The rebar basket T-2 assembled in this manner is stored in the rebar storage cart 13 as described above, and is built by the stowage crane 14.
