<< Embodiment >> An embodiment of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a front view showing the application of a preferred embodiment of a beam reinforcing bar assembly device according to the present invention.

In FIG. 1, reference numeral 1 is a beam reinforcing bar framing device according to the present invention, and 2 is a beam reinforcing bar framing device erected using the beam reinforcing bar framing device 1.

First, the beam reinforcing bar 2 is formed by arranging a plurality of beam main bars 20 in a predetermined arrangement to form a group, and a spiral reinforcing continuous reinforcement 21 is attached to the beam main bar group in the predetermined arrangement. At this time, a plurality of beam main bars 20 hold their longitudinal portions by the beam reinforcing bar assembling apparatus 1 in which a large number of them are continuously arranged on the long base 3 at appropriate intervals.

Next, this embodiment will be described with reference to FIGS.

This beam reinforcing bar framing device 1 is basically composed of arms 10 on which beam main bars 20 are placed, and columns 11 in which the arms 10 are horizontally arranged at intervals corresponding to the beam main bar group, And a hydraulic cylinder 12 serving as a driving means for moving the arm 10 arranged on the column 11 in the longitudinal direction thereof.

Then, the column 11 is formed by vertically arranging two sub columns 111, 111 on the base 110 with a space therebetween, and a hydraulic cylinder 13 for vertically sliding a slide block 100, which will be described later, is vertically erected on the tops of the sub columns 111, 111. Be prepared. This pillar 11 has a base 110.
The two bases 110 are slidable in the longitudinal direction of the base 3 when the bases 3 are installed on the base 3 by being fixed to the base 3, but when they are juxtaposed side by side as shown in FIG. And are connected to each other via a screw shaft 4. A handle lever 5 is fixed to one end of the screw shaft 4, and the base 3
A central portion of the support column 11 is axially supported by a bearing 6 projecting from the base 6. The two columns 11 and 11 arranged in parallel are connected to each other along with the rotation of the handle lever 5, that is, the rotation of the screw shaft 4. Sliding in the longitudinal direction, the distance between the two is adjusted appropriately.

A slide block 100, on which a brace 10 is arranged, is fitted between both sub-columns 111, 111 of the column 11 so as to be able to move up and down. In this embodiment, two slide blocks 100 are arranged at the upper and lower ends, respectively. The lower end of these slide blocks 100 is fixed to the base 110, and the upper end thereof is connected to the piston rod 130 of the hydraulic cylinder 13. Therefore, as the piston rod 130 of the hydraulic cylinder 13 expands and contracts, the upper end side slide block 100 connected thereto is moved up and down, and the interval between the upper and lower slide blocks 100, 100 is adjusted appropriately.

As shown in FIG. 4 to FIG. 7 in an enlarged manner, the slide block 100 is provided with a hole portion with which the armrest 10 is engaged, and the hole portion is in a state of being fitted upright. The slide block 100 is opened horizontally, and in this embodiment, two holes are provided slightly above and below the slide block 100, and the arm 10 is slidably inserted into the hole. It is projected from the slide block 100. That is, in this slide block 100, two arms 1
0s are spaced apart and arranged in parallel vertically, and these arms 10 and 10 are slidable in the longitudinal direction thereof.

The ends of the arms 10 connected in parallel vertically are connected to each other via a connection block 101, and the hydraulic cylinder 12 described above is arranged between the connection block 101 and the slide block 100. That is, this hydraulic cylinder 12
The main body is fixed to the slide block 100, and its piston rod 120 is connected to the connecting block 101. Therefore, as the piston rod 120 of the hydraulic cylinder 12 expands and contracts, the connecting block 101 connected to the piston rod 120, that is, the upper and lower arms 10 arranged in parallel vertically slide in the horizontal direction.

The arm bar 10 has a recess 102 formed on the upper surface of the end not connected to the connecting block 101, which engages with the circumference of the beam main bar 20, and the beam main bar 20 has a protrusion formed with the recess 102. Placed on the side.

On the other hand, the structure of the lower end side slide block 100 is similar to that of the upper end side slide block 100 described above except that it is fixed to the base portion 110, and therefore the description thereof will be omitted.

Therefore, when the beam reinforcing bar 2 is erected, first, the beam main bar 2 is attached to the arm bar 10 that horizontally protrudes from the slide block 100.
Place 0 to hold it. Where the upper and lower arms 1
By appropriately placing the beam main reinforcements 20 on 0, the beam main reinforcements 20 form a group having a predetermined arrangement. And
At this time, since the concave portion 102 is formed on the upper surface of the end portion of the arm bar 10, even if the placed beam main bar 20 slips, the concave portion 102 is not formed.
Therefore, the recess 102 can prevent the beam main bar 20 placed on the armrest 10 from slipping off. Further, since the interval between the upper and lower slide blocks 100, 100 can be adjusted appropriately by the expansion and contraction operation of the hydraulic cylinder 13, this means that the interval between the upper and lower arms 10 and 10 can be set appropriately. Arms 10
The vertical drive means for vertically moving up and down is provided, and the array size of the beam main bar 20 can be changed by changing the interval between the upper and lower arms 10 by the hydraulic cylinder 13, and various array sizes can be accommodated.

Next, the continuous shear reinforcing bar 21 in a spiral shape is fitted to the beam main bar group, and the beam main bar 20 is extended in the longitudinal direction,
They are fastened at appropriate intervals.
At the time of extension of 21, the arm 10 holding the relevant part for passing it is pulled out by the extension operation of the hydraulic cylinder 12, and after passing, it is made to project again by the shortening operation of the hydraulic cylinder 12, thereby Constructs the rebar 2 (ground structure). When the arm bar 10 is pulled out, the load of the beam main bar 20 which is being supported by the arm bar 10 is received by the arm bar 10 of the adjacent beam reinforcing bar framing device 1 arranged in parallel.

That is, according to such a configuration, the arm 10 is slid in the horizontal direction as the hydraulic cylinder 12 expands and contracts. Therefore, the arms 10 can be easily inserted and removed by detecting the extension of the shear reinforcing bar 21 by a sensor to automatically start the hydraulic cylinder 12, or by a simple instruction operation such as simply turning on the start switch of the hydraulic cylinder 12. 10 plugs can be automated. As a result, it is not necessary to manually insert and remove as in the conventional case, and the workability can be improved.

<< Advantages of Device >> As described in detail in the above, according to the beam reinforcing bar assembling device according to the present invention, the arms are moved in the longitudinal direction by the driving means, which causes the arms to move. Insertion and removal can be automated. Therefore, unlike the conventional case, it is not necessary to manually insert and remove, and the workability can be improved.
