DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cast-in-place pile reinforced cage construction device.

[0002]

2. Description of the Related Art Cast-in-place pile reinforced cages have conventionally been constructed using large cranes or portal cranes.

[0003]

Accordingly, the construction site has a narrow construction condition (for example, the width is about 5 m, and the working head is 4 m).
), Large cranes and portal cranes cannot be used, so if the weight of the reinforced cage is large, the construction work becomes difficult.

[0004] It is an object of the present invention to provide a cast-in-place pile reinforced cage installation device for safely setting a cast-in-place pile reinforced cage in a narrow construction site with good workability.

[0005]

According to the present invention, there is provided a cast-in-place pile reinforced cage installation device provided with a gantry disposed so as to surround an opening of a stand pipe, and a pair of winches opposed to the gantry. A device is provided, and those winch devices are provided with a pulley attached to a bracket provided on a gantry so as to face the inside of the stand pipe, and a winch mechanism for winding a wire rope having a hook at an end thereof. The hook suspends the reinforced basket on the side, and the reinforced basket is suspended while being supported by the side.

[0006]

In the cast-in-place pile reinforced cage construction device constructed as described above, the device is installed in the opening of the stand pipe, and the reinforced cage unit is moved over the opening with a small crane and the built-in reinforcement is reinforced. Connect with basket unit. Next, it is supported by a wire rope of a winch device, and is lowered and fixed to a predetermined position. Kanzashi which is usually used is used for fixing. Thereafter, connection and lowering of the reinforcing bar are performed in the same manner.

[0007]

Embodiments of the present invention will be described below with reference to the drawings.

In FIG. 1 and FIG. 2, a mounting device indicated by reference numeral 1 is a flat U-shaped base 2 provided so as to surround an opening of a stand pipe 10, and is opposed to the base 2. And a so-called chill hole, which is a winch device indicated by reference numeral 4 and provided as a whole.

Referring also to FIG.
A pulley 5 is provided so as to face the inside of the stand pipe 10 through the bracket 3 via a bracket 3, and a winch mechanism (not shown) having an operation lever 6 is provided. The winch mechanism is configured such that the wire rope 7 having one end free and a hook 8 at the other end is lowered by operating the operation lever 6 in the direction of the arrow a, and is hoisted by operating the operation lever 6 in the direction of the arrow b.

Next, a description will be given of a mode of installing the reinforcing bar.

First, as shown in FIG. 4, the reinforced cage unit 11A is suspended from the opening of the stand pipe 10 by a 4.9 ton mini crane 9, for example.
Supported by the wire ropes 7 and 7.

Next, the next reinforced cage unit 11B is suspended and connected to the reinforced cage 11A.

Then, as shown in FIG. 5, the operating levers 6, 6 are operated in the direction of arrow a to lower the wire ropes 7, 7 and suspend the reinforced cage units 11A, 11B in the guide pipe 10. Hereinafter, similarly, the reinforcing bar cage units 11C are successively added and suspended, and the reinforcing bar cages are built.

When connecting the reinforcing bar cage and changing the hook 8, it is fixed with a normally used kansashi.

[0015]

The present invention is constructed as described above. Therefore, it is possible to build a cast-in-place pile reinforced cage in a narrow construction site with good workability without using a large crane or a portal crane. Can be.

Further, the present invention is effective not only for the construction of steel stakes, but also for the construction of steel pipe columns and timber columns.
