Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a reinforcing mesh unit reinforcing machine and a reinforcing method for producing a structure such as a nuclear power plant.

[Conventional technology]

2. Description of the Related Art Conventionally, when constructing a structure of a nuclear power plant, most of the assembling of the reinforcing bar unit has to rely on human power, and all the arrangement work of reinforcing bars at regular intervals has been performed manually.

However, the reinforcing steel used for the structure of a nuclear power plant has a large diameter of about 38 mm, and is often as long as about 12 M in length, and the workability is poor due to its weight (about 100 kg). It required a lot of staff and it took a long time to arrange the bars. For example, when assembling a mesh-like muscle unit,
It took 5 to 8 people and 2.5 hours of work time to arrange the bars.

However, the construction industry in Japan has recently faced a situation of aging workers and a shortage of skilled workers.
There is a demand for an improvement in the on-site production method, and a device in which a part of the assembling work of the reinforcing bar unit is mechanized has been developed (for example, JP-A-57-154343).

[Problems to be Solved by the Invention] However, in the above-mentioned Japanese Patent Application Laid-Open No. 57-154343, there is no automatic processing line for automatically arranging reinforcing bars and welding them into a reinforcing bar mesh shape.

Further, as shown in FIGS. 9 to 11 of the above publication, all of the supplied vertical streaks 2 are supplied between the claws 44a of the conveyor 44, and after the vertical streaks 2 are moved below the conveyor 44, Since the vertical stripes are arranged by moving the vertical stripes 2 by engaging the vertical stripes 2 with the grooves 29 of the rollers 30, the fixed stripes 47 and the movable stripes 48 are required by the number of the vertical stripes,
Further, since the entire weight of the vertical stripe is applied to the movable piece 48, there is a problem that the durability is reduced and the driving mechanism is also large. Further, the arrangement pitch of the vertical stripes is uniquely determined by the interval between the claws 44a, and there is a problem that a significant change in the automation line is required when manufacturing different pitch products.

The present invention solves the above-mentioned problem, and has a reinforcement mesh unit with a simple configuration, which enables a system for automatically producing all the assembly processes of a reinforcement mesh unit (including a bend mesh unit) and a reinforcement machine.

Next, another embodiment of the present invention will be described with reference to FIG. 7, FIG. 8 and FIG.

FIG. 7 is a conceptual diagram of a rebar prefabricated unit automatic assembling apparatus of the present embodiment.

In FIG. 7, reference numeral 101 denotes a plurality of jigs which are fixed at a predetermined pitch and are provided in at least two rows of chain conveyors which are rotated at the time of supplying vertical streaks, and which are provided so as to be able to move up and down between the chain conveyors. This is a reinforcing bar bed composed of a roller conveyor that is raised and rotated during supply. At the edge of the bar arrangement bed 101, a vertical line supply device 102 and a horizontal line supply device 103 are provided at right angles to each other, so as to supply pitch vertical lines and horizontal lines at predetermined intervals on the bar arrangement bed. . In addition, a binding machine 104 for connecting the vertical and horizontal streaks is provided adjacent to the horizontal streak supply device 103.

The vertical streak supply device 102 is composed of a pair of left and right supply devices, and one rebar is supplied from each supply device toward the center. Reference numerals 109 and 109 'denote chain conveyors for supplying vertical bars. The vertical bars placed on the chain conveyor are sequentially sent to a reinforcing bar size adjusting device 110. The rebar slides on the rolling surface 115 and fits into the groove 117 of the support bar 116. Next, rebar 1 in groove 117
19 is attracted by a magnet 121 which is moved up and down by a motor 120, and is placed on the bar arrangement bed 101.

Are moved in synchronization with the lowering operation of the magnet 121, so that the reinforcing bars supplied from the pair of left and right supply devices 102 are simultaneously arranged two by two on the chain conveyor 123. The chain conveyor 123 has jigs 124 of the number necessary for arranging the vertical streaks. Has
The operator of the reinforcing bar prefabricated unit automatic assembling apparatus can select a required pitch interval of the jigs 124 above and below the chain conveyor 123 before starting the bar arrangement operation.
The chain conveyor 123 rotates, and the first jig 124 in the selected row of jigs 124 is set below the elevating magnet 121.

In addition, although the figure consists of a pair of left and right supply devices, it may be composed of only a single bar arrangement device. Also,
Although not shown, a single horizontal streak supply device having the same structure as that of the pair of supply devices shown on the right side of FIG. 8 is used.

Further, as shown in FIG. 9, two upper and lower supply units may be provided. In this case, another support bar 125 is provided below the support bar 116, and by supplying a large-diameter rebar 119 'to the support bar 125, mesh units having different rebar diameters can be obtained every other bar. .

FIG. 10 shows a roller conveyor for moving the vertical streaks arranged at a predetermined pitch on the bar arrangement bed 101 by one pitch of the horizontal streaks. A drive roller 126 is rotatably supported below the chain conveyor 123. The roller conveyor is installed on a support 128 that can be moved up and down by an elevating mechanism 127. The roller conveyor goes down when the vertical bars are laid, but when the vertical bars are finished and the row of vertical bars is moved by one pitch of the horizontal bars for arranging the horizontal bars, it rises. As shown at 129, the vertical stripe 119 can be lifted from the chain conveyor 123. If the drive roller 126 is rotated in this state, the row of vertical stripes can be moved.

Note that the present invention is not limited to the above embodiment, and various modifications are possible.

For example, the bar arrangement bed, the vertical bar supply device, and the horizontal bar supply device can be disassembled into respective blocks, and further, can be disassembled into several blocks of a transportable size, thereby facilitating transport assembly. You may do so.

〔The invention's effect〕

As described above, according to the present invention, the arrangement of the vertical streaks and the arrangement of the horizontal streaks are performed by a mechanical device, thereby enabling a system for automatically producing all the assembly processes of the reinforcing bar mesh unit. Therefore, the number of personnel is small, and the time required for assembly is short. For example, when assembling a mesh-shaped muscular unit, four people required five to eight people for the arranging work, and 30 minutes required 2.5 hours of work time. I get stuck.

In addition, bend bars can also be arranged without being limited to the linear reinforcing bars, and there is versatility and productivity can be sufficiently improved.

Further, as compared with the vertical streak supply method disclosed in Japanese Patent Application Laid-Open No. 57-154343, a fixed piece, a movable piece and a drive mechanism are not required, and the structure can be simplified and the durability can be improved. Since it is a system in which the vertical streaks are supplied one by one to the reinforcing bar, it is possible to easily cope with a case where products of different pitches are manufactured.
