[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a jig for assembling a reinforcing cage, and more particularly, to a plurality of assembling bars extending substantially parallel to a circumferential direction at required intervals, and an outer side of the assembling bars. The present invention relates to an assembling jig capable of efficiently performing a binding operation with a spiral muscle wound spirally.

[0002]

2. Description of the Related Art In the manufacture of a concrete cast product such as a concrete pile, a reinforcing steel basket is generally used as a core for reinforcing the product. In this cage, a plurality of reinforcing bars (hereinafter referred to as "axial bars") composed of long members are circumferentially separated at a required interval in parallel to form a substantially cylindrical shape, and another reinforcing bar is provided outside the cylindrical shape. Reinforcing bar made of length members
(Hereinafter, referred to as “assembled streaks”) are similarly arranged in a substantially cylindrical shape, and a wire called “spiral streaks” is spirally wound around the outer periphery of the cylindrical assembling streaks. In order to manufacture the reinforcing cage, first, the plurality of shaft bars and the assembling bars are horizontally fixed between a pair of support plates arranged at predetermined intervals in the axial direction, and both bars are appropriately fixed. Positioning and fixing are relatively performed by the holding member. Then
In a state where the spiral muscle is wound around the outer circumference of the plurality of assembling muscles, it is general that a portion where the assembling muscle and the spiral muscle intersect is bound with a wire or an appropriate clip. In this cage, strength is obtained by the shaft muscle and the spiral muscle, and the assembly muscle is used for holding the spiral muscle.
The basket is used not only as a core of a concrete pile, but also as a reinforcing core such as a water guide pipe having a polygonal cross section or a caisson for a submersion method.

[0003]

As described above, the assembling wire around which the helical muscle is wound around the outer periphery is supported with both axial ends fixed to the support plate. For this reason, if the assembling muscle becomes long, the assembling muscle will hang down between the two support plates, and when binding the assembling muscle and the helical muscle, the worker performs the binding operation while holding the assembling muscle. This had to be done, which was a very complicated task. In addition, in order to bind a large number of intersections between the assembling muscle and the helical muscle, it is necessary for an operator to move with respect to the stationary cage body which is fixedly located. That is, for example, when the binding of the intersection facing the side facing the worker is finished first,
At present, the worker moves to the opposite side of the reinforcing cage to perform the binding work. Further, depending on the height position at which the reinforcing basket is supported, the worker is forced to perform the binding operation in an unnatural posture in which the operator leans down, and there is a problem that the working efficiency is reduced.

[0004]

SUMMARY OF THE INVENTION The present invention has been proposed to solve the above problems inherent in the work of binding the reinforcing cage, and it has been proposed to suitably solve the problem. It is another object of the present invention to provide means for efficiently performing a binding operation in a comfortable posture.

[0005]

SUMMARY OF THE INVENTION In order to preferably overcome the above-mentioned problems and achieve the intended object, the present invention provides a plurality of assembling lines extending substantially parallel to a circumferential direction at required intervals, and the assembling lines.

(Supply Apparatus) As shown in FIG. 8, the supply apparatus 67 of the binding tool 64 has a guide member 69 capable of slidably loading a plurality of clips 65 in a series state. A moving body 71 moved forward and backward by the air cylinder 70 is provided. An air cylinder 72 orthogonal to the air cylinder 70 is provided at the tip of the moving body 71, and an engagement pin 73 is attached to a piston rod (not shown) of the air cylinder 72.
Is arranged. This engagement pin 73 is
By the forward / reverse biasing of (2), the clip 65 is set at a standby position where it does not interfere with the clip 65 loaded on the guide member 69 and at an operating position where the clip 65 is engaged with the fitting portion 65a. That is, the air cylinder 70 is loaded on the guide member 69 by biasing the air cylinder 70 in the forward direction in a state in which the engagement pin 73 is engaged with the fitting portion 65a of the clip 65 by biasing the air cylinder 72. The clips are transferred toward the coupling device 66 by a predetermined pitch. The stroke of the air cylinder 70 is set to a size that allows the clips 65 to be sent out to the coupling device 66 one by one.

(About the Coupling Device) As shown in FIG. 8, the coupling device 66 is used to open and close a pair of clipping jaws 74, 74 (only one is shown) and to open and close both clipping jaws 74, 74. And an air cylinder 75 to be operated. The coupling device 66 and the supply device 67 are connected to an air cylinder 75.
Are arranged so that the direction in which the clip extends and the direction in which the clip is delivered intersect, and the fitting portion 65 a of the clip 65 delivered from the supply device 67 is set so as to face the air cylinder 75. Further, the air cylinder 75 is provided with a gripping position at which the clipping jaws 74, 74 are lightly gripped by the clip 65, and a swaged portion 65b, 6 of the clip 65.
The urging control is performed so that 5b can be closed stepwise to the caulking position where "caulking" is performed.

(Regarding the moving device) As shown in FIG. 8, outside the air cylinder 75 constituting the coupling device 66, another air cylinder 77 disposed on the cylinder 75 can move reciprocally within a required range. A bar 76 is provided. The end of the moving bar 76 that faces the clipping jaw 74 is disposed and fixed to the guide member 69 of the supply device 67. Therefore, by urging the air cylinder 77 forward and backward, the moving bar 76 and the supply device 67 reciprocate within a predetermined range. The air cylinder 77 positions the supply device 67 at a supply position where the clip 65 can be supplied to the clipping jaws 74 and 74 of the coupling device 66 and a standby position where the clip device is retracted from the clipping jaws 74 and 74 to the air cylinder 75 side.

[0026]

Next, the operation of the jig for assembling the reinforcing cage according to the illustrated embodiment will be described.

First, with one half 18a of each of the second support plates 18 removed, the other half 18a is placed on the grooved rollers 28, 28 such that the open end of the other half 18a faces upward. Then, the shaft 12 is inserted into each of the second through holes 16b formed in the first support plates 16, 16 so as to be substantially cylindrical. At this time, the holding ring 47 is previously extrapolated outside the plurality of shafts 12 and the holding ring 47 is
The claw provided on the ring 47 is “slung” to each of the axial muscles 12 in a state of facing the position not interfering with the support plate 18. Further, outside the axial muscle 12, three sets of spiral muscles 49 tightly wound in a coil shape are extrapolated. In addition, one set of coiled spiral muscle 49
Is set to a length dimension that can be spirally wound around the assembling line 14 facing between the support plates 16 and 18 at a required interval in the axial direction.

Next, the assembling struts 14 are respectively inserted into the first through holes 16a formed in the first support plates 16 and 16 to have a substantially cylindrical shape. The helical muscle 49 faces. Also, the claws of the holding ring 47 extrapolated to the shaft bar 12 are “crimped” to the corresponding assembling bars 14 so that the shaft bars 12 and the assembling bars 14 are fixed to each other.

After the assembling studs 14 and the shaft studs 12 are held between the first supporting plates 16 and 16 in a substantially cylindrical shape, the half of the second supporting plates 18 and 18 is removed. 18a, 1
8a is fixed via fixing members 36 to the halves 18a, 18a supported by the grooved rollers 28, 28. At this time, the assembling line 14 is inserted into the through hole 18b of the second support plate 18.
And the axial muscle 12 face. Then, the hooks 46 of the support members 38 arranged on the respective second support plates 18 are hooked on the corresponding assembling bars 14 or the shaft bars 12, as shown in FIG.
Thereby, the assembling struts 14 and the shaft struts 12 inserted into the through holes 18b are held in a horizontal state with respect to each other, as shown in FIG. Also, the through holes 16a, 16b of each first support plate 16
Are fixed by the fixing means 42. As shown in FIG. 5, by screwing the bolt 32 of the fixing means 42 into the nut 30 facing the outside of the first support plate 16, the assembling line 14 and the axial line fixed to the bolt 32 via the bush 34. 12 will be pulled in the axial direction, and the streaks 14,
12 in a state where the bending and the like of the first support plate 12 are corrected.
It is held between 6,16.

As shown in FIG. 2, each spiral muscle 49, which is extrapolated to the assembling muscle 14 and closely wound in a coil shape, is loosened in the axial direction as shown in FIG. It is made to face the outside of the assembling line 14 so as to be spaced.

In this state, as shown in FIG.
For example, the bundling tool 64 is supported by a balancer 81 suspended by an overhead traveling crane (not shown) provided at a manufacturing site of the reinforcing cage. The operator holds the binding tool 64 and presses a required operation button 64a, so that the clip 65 loaded on the guide member 69 is connected to the joining device 66.
To supply. As a result, the clip 6 is attached to the clipping jaws 74, 74 which are waiting in the open state of the coupling device 66.
5 is gripped.

Next, the operator operates the clipping jaws 74,
The clip 65 gripped by 74 is positioned close to the intersection between the assembling line 14 of the reinforcing cage and the spiral 49, and the fitting portion 65 a of the clip 65 is fitted to the spiral 49. Then, by pressing the operation button 64a and closing both clipping jaws 74, 74 to the swaging position, as shown in FIG. 7, the two swaging portions 65b,
65b is "crimped" by the assembling line 14,
And the helical muscle 49 are firmly bound.

As described above, after the worker binds the binding portion (the intersection of the assembling muscle 14 and the spiral muscle 49) facing the one side of the reinforcing cage with the binding tool 64 with the clip 65,
The support motors 16 and 18 are rotated by a required angle by the index motor 20. As a result, the unbundled portion faces the side opposite to the worker, and the worker can continue the bundling work on the same side.

Further, after binding the facing support plates 16, 18 or the binding portion facing between the support plates 18, 18,
When binding the assembly muscle 14 and the helical muscle 49 where the second support plate 18 faces, all the assembly muscles 14
The support member 38 is removed from the shaft support 12 and the half body 18a facing the upper side of the second support plate 18 is removed. Then, in this state, a binding operation of a binding portion facing a position that does not interfere with the half body 18a is performed. Next, the support plates 16 and 18 are rotated by the indexing motor 20 to bind the remaining binding portions. The spiral muscles 49, 49 facing both sides of each second support plate 18 are bound in a state of being wrapped about one turn.

In the embodiment, the case where the base on which the first support plate and the second support plate are rotatably mounted is fixedly arranged on the floor has been described, but the present invention is not limited to this. . For example, if each base is movably mounted on a rail or the like, and each grooved roller is spline-connected to the drive shaft, the spacing between each support plate can be changed according to the length of the reinforcing cage. Can be done. In this case, each base can be configured to be movable and positioned by an appropriate driving unit.

[0036]

As described above, according to the jig for assembling the reinforcing cage according to the present invention, the assembling streak can be held horizontally by the first support plate and the second support plate. It is not necessary for an operator to hold the assembly muscle when binding the helical muscle with the assembly. In addition, since each support plate is configured to be rotatable and indexed, the operator can perform binding work at all binding locations simply by being on one side of the reinforcing cage held by the assembly jig. Efficiency can be improved. Further, since the binding portion of the reinforcing basket can be positioned at a position where the worker can perform the binding operation in an easy posture, there is an advantage that labor can be reduced.
