Abstract

PROBLEM TO BE SOLVED: To enhance safety and workability by suspending a raising-lowering mast by a laterally traveling carriage arranged in a self-traveling gate-shaped girder, and transferring product reinforcements by freezing a pair of clamp devices through a turing device and a derricking gear. SOLUTION: Reinforcement materials (s) are unloaded on material sending stands 2a and 2b from a material carrying-in truck 1 by a reinforcement assembling machine 10, and are inputted to a reinforcement cutter 3a and a reinforcement bender 3b. Next, worked product reinforcements S are transferred to a product reinforcement receiving stand 4a and a product reinforcement temporary storage place 4b, and a prescribed quantity of product reinforcements S is transferred to a temporary storage stand 27 of a girder 11. Next, in a net reinforcement assembling stand 5, longitudinal reinforcements S1 and lateral reinforcements S2 of the product reinforcements S are arranged, and after a net reinforcement is assembled by binding crossing parts of both reinforcements S1 and S2 together, it is transferred to a net reinforcement product storage place. These various works are consistently performed by a single reinforcement assembling machine 10. Therefore, workability is improved by a lightweight and inexpensive device, and cycle time can be shortened.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for assembling rebar at a construction site.

[0002]

2. Description of the Related Art Assembling rebar at a construction site
Since it will be a critical path for construction, it can be shortened by loading it into the site after prefabricating it into a net-like shape at a rebar processing plant.

Also in this field assembly, conventionally, a bundle of rebars that have been temporarily transported by a crane or the like is prepared beside the assembly range, and a plurality of rebar workers manually select one rebar and lift it to move it. It is made of wood. Also, a device has been developed in which a plurality of reinforcing bars are housed in a cartridge, mounted on a gantry or a hydraulic excavator, and distributed by a handling device or the like.

[0004]

SUMMARY OF THE INVENTION In the conventional manual assembly,
Workability is poor due to the cooperation of multiple reinforcing bars, and there are safety and health problems.

On the other hand, since the conventional mechanization device is provided with the cartridge, it has a strong structure due to its large weight, and its physical condition is low compared to the cost because of its maneuverability (cycle time etc.). Further, if the cartridge is set manually, the labor saving effect is impaired, and if it is mechanized, the weight and the cost are increased.

[0006] It is an object of the present invention to provide a lightweight and low-cost rebar assembly apparatus which improves safety and workability.

[0007]

According to the present invention, the rebar material yard, the processing machine, the product rebar yard, the net rebar assembly mount, and the rails laid on both sides of the net rebar product yard are arranged in series according to the present invention. A running net reinforcing bar assembling apparatus, wherein a traversing carriage provided on the self-propelled gate type garter, the net reinforcing bar assembling apparatus includes a self-propelled gate type garter, and an elevating mast suspended from the self-propelled cart. The lifting mast is provided at its lower end with a pair of clamp devices connected to each other via a turning device and a hoisting device.

The self-propelled gate type garter is provided with a rebar temporary mounting stand.

In the net rebar assembling apparatus constructed as described above, the gantry girder travels, the traverse of the traverse carriage, the elevating and lowering of the lifting mast, the turning of the clamp device, the undulation and the unloading and processing of the rebar material storage area by the clamp. It is possible to consistently move to the machine, move from the processing machine to the product rebar yard, install from the product rebar yard to the net rebar assembly mount, and move from the net rebar mount to the net rebar product yard.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings.

In FIG. 1, at the construction site, there are a material feed table 2a, 2a which is a rebar material storage area for wholesale of the rebar material s of the material loading truck 1, a rebar cutting machine 3a and a rebar bending machine 3b which are processing machines. The product cradle 4a and the product rebar temporary yard 4b, which are the product rebar yard, the net rebar assembly stand 5 and the net rebar product yard not shown are arranged in series, and the beams 6 and 6 are provided on both sides thereof. Rails 7, 7 (Fig. 2) are laid. Further, on the rails 7, 7, a reinforcing bar assembling machine generally designated by 10 is provided so that it can travel.

Referring also to FIGS. 3 to 6, the reinforcing bar assembling machine 1
0 is provided with a pair of saddles 11 that are driven by traveling wheels 12 and a traveling drive device 13.
1 is connected to each other in a gate shape by a garter frame 15 via a pair of columns 14. That gata frame 1
5, a pair of traverse rails 16 is laid, and a traverse carriage 17 driven by a traverse drive device 18 is provided on the traverse rails 16, 16. A mast 20 is vertically movable by a vertical mast lifting device 19 on the traverse carriage 17, and a turning device 21 is provided at a lower end of the mast 20. A base 22 is fixedly mounted on the swivel device 21, and the arm 2 is attached to one end of the base 22.
3 is pivotally mounted and is hoisted by a hoisting cylinder 24. A center of a shoulder frame 25 is fixed to the arm 23, and a clamp device 26 according to a known technique is provided at both ends of the shoulder frame 25. In the illustrated example, one saddle 11
In addition, a temporary stand 27 for the product rebar S is provided. In the figure, reference numeral 28 is a hydraulic unit, and 29 is a control panel.

Next, the assembling mode will be described.

The reinforcing bar assembling machine 10 runs on the rails 7, 7, traverses the traverse carriage 17, lifts the mast 20, swings the clamp devices 26, 26, and lifts and clamps the reinforcing bar material s and the product. The rebar S and the net rebar product can be gripped and transferred to any place.

With this rebar assembling machine 10, the rebar material s is wholesaled from the material loading truck 1 to the material feed bases 2a and 2b, and is fed into the rebar cutting machine 3a and the rebar bending machine 3b to be processed. 4a, product rebar is transferred to temporary storage 4b. Therefore, a predetermined amount of the product rebar S is transferred to the temporary placement stand 27 of the garter 11, and the longitudinal bar S1 and the lateral bar S2 of the product rebar S are laid on the net rebar assembly stand 5, and both bars S1 are formed by a known means. , S2 are assembled at the intersections of S2 to assemble the net rebar, and then the net rebar is transferred to the product area. These various operations are consistently performed by one rebar assembly machine 10. Therefore, unlike the conventional method, the product rebars are not distributed one by one from the product rebar temporary storage 4b to the net rebar assembly rack 5, so that the cycle time is shortened.

[0016]

Since the present invention is constructed as described above, it is possible to improve the safety and workability and shorten the cycle time by means of a lightweight and low-cost device.
