Description

[Detailed explanation of the invention] This invention is based on the idea that after a concrete column such as a concrete pile or a ball is shaped using a forming form consisting of an upper formwork and a lower formwork that are divided into upper and lower halves, the concrete column is This invention relates to a frame disassembly cart used to divide the body into upper and lower parts and disassemble the frame when removing the body from the modeling frame.

In the conventional formwork removal work, the formwork that has completed curing is rolled on a transfer table so that the fastening lugs of the upper and lower forms are approximately horizontal, and then the formwork is hoisted by a crane and transferred, for example, to a dolly or conveyor, and the fastening bolts fastening the fastening lugs are removed on the dolly, etc. However, since this method involves the rolling of the formwork and the crane hoisting operation, it has the disadvantage that the safety and efficiency of the work are easily compromised.

Therefore, this invention was proposed in order to solve the above-mentioned defects.In particular, it is equipped with a trolley for transporting the conventionally known concrete column forming form, and the floor at the bottom of the center of the trolley is Utilizing a device equipped with a cylinder on the surface, and using this as the conventional prior art, a support shaft parallel to the rail for running the truck is attached to the truck frame of the truck near the transfer part of the formwork containing the concrete column body. One end of the arm is pivotally supported on this support shaft, and the upper end surface of the piston 15 of the cylinder 16 provided on the floor adjacent to the transfer section 3 is brought into contact with the lower surface of the arm 9. The arm 9 is formed to be tiltable by the movement of the piston 15 in and out, and the support shaft is connected to a motor so that it can be driven, and a roller is rotatably supported at the other end of the arm. In addition, it is an object of the present invention to provide a cart for dismantling a concrete column forming form, characterized in that a roller is also fixed to the support shaft.

Hereinafter, embodiments of this invention will be described in detail with reference to the accompanying drawings. For convenience of explanation, conventionally known configurations will also be explained at the same time. As shown in FIG. 1, a transfer section 3 such as a transfer table or a transfer cart is provided to roll or transfer the formwork 2, which has been cured in the curing tank 1 and is still inside the concrete column, in the lateral direction. Therefore, the rails 4, 4 approaching the transfer end 3a of the transfer section 3 are arranged, and the trolley 5, which is large enough to transfer the formwork 2, is disassembled using the rails 4, 4. It will be possible to transport it to work area 6. and the second
As shown in the figure, a support shaft 8 parallel to the rails 4, 4 is provided in the cart frame 7 of the cart 5 close to the transfer end 3a, one end of an arm 9 is pivotally supported on this support shaft 8, and A wheel 10 is rotatably supported at the other end of the arm 9. Further, as shown in the illustrated example, the other roller 11 is fixed to the support shaft 8, and the support shaft 8 is connected to a motor (not shown) via a speed reduction mechanism so that it can rotate. In addition, this arm 9 can be moved to the second position by an ejecting rod 13 which is guided by a lock guide 12 attached to the bogie frame 7 and can protrude upward, or by the upper part of the bogie frame 7.
It is formed to support approximately horizontally as shown in the figure,
In this horizontal support position, the left and right wheels 10,
11 allows the tire portion 2a of the formwork 2 to be held stationary. Incidentally, if a plurality of rolling wheels 10 and 11 are provided along the direction of the rails 4, 4 as described above, the stability of supporting the formwork 2 can be improved.

When the truck 5 is in the transfer work area 14 as shown in the lower part of FIG. As shown in FIG. 3, the arm 9 is supported by a piston 15 in a position where the rollers 10 on the back side are on the upper side, and the formwork 2 before being dismantled is transferred from the transfer section 3 to this trolley. 5, when the formwork 2 is transferred to the rear wheel 10
When it comes into contact with the cylinder 16, the arm 9 is rotated downward while gradually discharging the pressurized air in the cylinder 16, either by manual insertion or by automatic operation such as by pushing a sensor such as a limit switch in the formwork 2. In this way, the arm 9 is lowered while damping the rolling impact force caused by the transfer of the formwork 2.
It is configured to be in the horizontal support position shown in FIG. At this time, the support shaft 8 is provided close to the transfer section 3 of the formwork 2 and is rotated gently by the motor, so that the formwork 2 is not transferred from the transfer section 3 onto the trolley 5. When it is rotated, the formwork 2 is rolled on both the wheels 10 and 11 as the roller 11 pivoted on the spindle 8 rotates. Therefore, the tightening bolt 1 of the formwork 2
The positions of 8, 18, . . . can be controlled to be vertical.

Since the frame disassembling trolley according to this invention is constructed as described above, in order to transfer the formwork 2 from the transfer section 3 to the trolley 5, the piston 15 is raised and the rolling wheels 10
Hold arm 9 so that
When the piston 15 is transferred to the trolley 5, the piston 15 is gradually lowered by manual or automatic operation.
At this time, the arm 9 returns to the horizontal support position while the rolling impact caused by the formwork 2 is buffered by the spring action of the compressed air remaining in the cylinder 16. At this time, the roller 1 fixed to the support shaft 8
If 1 is rotated by a motor not shown, formwork 2
Also, the left and right clamping ears 2d,
The posture can be adjusted so that 2e, 2d, and 2e are approximately horizontal. So, move the trolley 5 to the rail 4,
4 to the frame dismantling workshop 6, and tighten the bolts 1.
8 with a bolt loosener (not shown), the cart 5 is returned to the transfer work area 14, and, for example, the formwork 2 is transferred together with the concrete columns to a demolding work area (not shown) using a crane or the like. As mentioned above, the trolley 5 is returned to the transfer work area 14 again.
The arm 9 is rotated upward by the piston 15 on the side of the roller 10 using the support shaft 8 as a fulcrum,
As a result, the formwork 2 is maintained in the receiving preparation posture described above.

Therefore, according to this invention, by rotating the formwork 2 transferred to the trolley 5 together with the wheels 10 and 11, the tightening bolts 18 can be easily controlled to change to the vertical position. This makes it extremely easy to remove the tightening bolts 18.
