Abstract

PROBLEM TO BE SOLVED: To make wired bars forming a reinforced cage by means of a simple method and device. SOLUTION: Reinforcing bars mounted on a holding platform 33 of a reinforcing bar arrangement machine 30 are supplied on a turn-table 42 of a wired bar assembly truck 40 one by one to mount. Whenever the reinforcing bars are mounted on the turn-table one by one, the truck 40 is moved to the reinforcing bar arrangement machine 30 side by an arrangement interval. When the arrangement of vertical reinforcement is completed, the truck 40 is moved backward, the turn-table 42 is turned at 90 deg. to arrange horizontal reinforcement on the vertical reinforcement to obtain wired reinforcing bars.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reinforcing bar arranging device and a reinforcing bar arranging method which are used for manufacturing a large-scale concrete structure such as a caisson.

[0002]

2. Description of the Related Art At a caisson production site, dozens of rebar materials carried by trucks are transported in a bundled state, and the bundle of rebars is temporarily placed on a ground storage site. Then, the operator selects a reinforcing bar from among the bundled reinforcing bars temporarily placed, and arranges the reinforcing bar in the reinforcing bar in the rebar reinforcing process.

[0003] The work is performed by gripping the rebar with a handling device of a rebar arrangement machine and moving the gripped rebar in the height direction (Z direction).
And moving it in the front-rear and left-right directions (X and Y directions) to arrange the reinforcing bars on the reinforcing bar assembly truck.

[0004]

However, the conventional method and apparatus for arranging reticulations are complicated in that the operation (movement) thereof is three-dimensionally performed in the height direction and in the front-rear and left-right directions. In order to arrange vertical and horizontal streaks at an accurate pitch to form a net streak, a high degree of control is required and the apparatus becomes expensive.

[0005] Accordingly, the present invention provides a reinforcing bar arrangement device and a reinforcing bar arrangement method which can obtain a desired reticulation bar by arranging vertical and horizontal streaks at an accurate pitch with a simple method and apparatus. It was done for the purpose of doing.

[0006]

According to the present invention, there is provided a reinforcing bar arranging machine and a reinforcing bar assembling trolley. The reinforcing bar arranging machine includes a bogie that runs on rails and is erected on the bogie. A cradle for placing rebars on the top of the gantry, and a conveyor for transferring rebars one by one from the cradle to a rebar assembly trolley located below the cradle. A bogie that runs on a rail laid inside the rails of the machine, and a turntable that is provided on the bogie and places a rebar sent by a conveyor of a rebar arrangement machine,
The turntable is provided with a defining tool for defining a bar arrangement interval.

According to the present invention, the reinforcing bars placed on the cradle of the reinforcing bar arrangement machine are sent one by one to a rebar assembling trolley located below by a transport conveyor and placed on a turntable of the trolley. When the placement of one reinforcing bar is completed, the rebar assembling trolley is moved to the reinforcing bar arranging machine side by a bar arranging interval specified by the defining tool, and thereafter, the vertical bars (horizontal bars) are similarly placed on the turntable.
When the reinforcement of the vertical bars (horizontal bars) is completed, move the rebar assembling trolley away from the reinforcing bar machine and turn the turntable 90 degrees, and use the vertical bars (horizontal bars) as in the case of the vertical bars (horizontal bars). Arrange a horizontal line (vertical line) on the (horizontal line).

[0008] Reinforcing bars are sent one by one from a cradle of a reinforcing bar arrangement machine to a rebar assembling trolley one by one by a transport conveyor, placed on a turntable of the trolley, and the rebar arranging trolleys are rebar-arranged by the rebar arrangement interval. By moving it to the machine side, the arrangement of vertical streaks (horizontal streaks) is made.
Since the horizontal streak (vertical streak) arrangement is performed by performing a similar operation after turning 0 degrees, the vertical streak and the horizontal streak are arranged at an accurate pitch with a simple movement, and the net streak is arranged. Obtainable.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 12 shows a work process of caisson making work in which a net reinforcement arrangement and a net reinforcement method according to the present invention are suitably employed.

[0010] Dozens of rebar materials T conveyed 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 assembling / transporting trolley 4 having completed the rebar arrangement is moved to the rebar binding process 5 and bound by the automatic binding machine 6.

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

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

The reinforcing cage T-2 is lifted and built by the mounting crane 14 by using the lot of the extended hanging lot 9.

The caisson structure is a rectangular caisson K. For the side wall formwork, the outer formwork 15 and the inner formwork 16 are integrated together. Lift up with the top mounted.

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

As mentioned above, the reinforcing bar arrangement machine 3 used in the reinforcing bar arrangement process 2 in the caisson construction work grasps the reinforcing bar T with the handling device and raises the grasped reinforcing bar T as described above. In the vertical direction (Z direction)
In addition, since it is moved in the front / rear and left / right directions (X and Y directions) and the reinforcing bars are arranged on the reinforcing bar assembling / transporting vehicle 4, the operation (movement) is complicated, and the pitch is accurate. Arranging the vertical and horizontal streaks requires a high degree of control and makes the device expensive.

The present invention has solved the above-mentioned problems of the conventional reinforcing bar arrangement machine by means described below, and an embodiment thereof will be described with reference to the drawings.
