2. Description of the Related Art At a construction site or the like, excess ready-mixed concrete (remaining concrete) after pouring work or when washing a mixer truck is put in, for example, a unicycle, solidified, and then discarded at a disposal site.

[0003]

However, the unicycle is not stable and easily falls, and moving with the solidified concrete in it is a troublesome force work. Especially, a large unicycle is heavy. It is not only difficult to move, but also dangerous. Also, when removing solidified concrete from a unicycle, the concrete is difficult to separate from the unicycle, which is troublesome. On the other hand, if residual concrete is poured to the site (ground), it may flow into the gutter and become clogged, so this must also be avoided.

The present invention has been made in view of such conventional problems, and an object of the present invention is to provide a means capable of easily performing the disposal processing of the residual condensate.

[0005]

In order to achieve the above-mentioned object, the bucket for discarding residual concrete according to claim 1 of the present invention comprises:

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described below based on embodiments. FIG. 1 is a front view of a bucket for discarding residual concrete according to the embodiment, FIG. 2 is a right side view, and a plan view (top view).
Is shown in FIG. The bucket 1 for discarding residual consumables has a shape as shown in the drawings, and one part (half part) 10 and the other part of the same shape in which upper parts serving as opening parts are axially supported so that the bottom parts can be opened and closed. It consists of a part (half part) 11. Both half portions 10 and 11 have the same shovel shape, and a support shaft 12 is erected on the upper part that is an opening. Both half portions 10 and 11 can rotate in the arrow direction with the support shaft 12 as a fulcrum, and the bottom portion Can be opened and closed.

The two half portions 10 and 11 are attached to the support shaft 12 by forming holes in the pair of upper fulcrum portions 10a and 11a of the two half portions 10 and 11, respectively, and then attaching the support shafts to the holes. It is performed by inserting 12 (see FIG. 3).
reference). Upper fulcrum parts 10a, 11 of both half parts 10, 11
By expanding the fulcrum portion 10a to the outside of the fulcrum portion 11a of the a, the both half portions 10 and 11 can easily rotate without the fulcrum portions 10a and 11a contacting each other. Of course, for example, the end portion of the support shaft 12 is curved or a ring is fitted to the end portion so that the support shaft 12 does not come off from the fulcrum portions 10a and 11a.

On the front side of this bucket 1, both half portions 1
A fixture is provided to lock the 0, 11 closed state. Here, the fixture includes a U-shaped lever 20, a shaft 21 that rotatably supports one end of the lever 20, and a shaft 22 that fits into the U-shaped notch 20a at the other end of the lever 20. Composed of. The shaft 21 is attached to the side surface of the half portion 11, the shaft 22 is projectingly provided on the side surface of the half portion 10 so as to correspond to the shaft 21, and the lever 20 is rotatable in the arrow direction with the shaft 21 as a fulcrum. In addition, these levers 20 and shafts 21 and 22
Similarly, the fixing device constituted by may be provided on the rear side of the bucket 1, and by providing the fixing device on the front and rear sides, it is possible to reliably lock the closed state of the half portions 10 and 11.

Legs 30 for supporting the bucket 1 are provided at the four corners of the bottom of the bucket 1. A flat plate-shaped pedestal 32 is attached to the lower end of each leg 30, and a caster 33 is detachably attached to each pedestal 32. Since the casters 33 are attachable / detachable, the bucket 1 is supported by the pedestal 32 when the casters 33 are removed.

Further, hook hooks 15 are attached to the upper four corners of the bucket 1 so that the bucket 1 can be lifted by a crane vehicle or a unic truck. By using this hook hook 15, the bucket 1
Can be easily moved to a higher place. In addition, two hook hooks 17 are attached to the lower parts of the half parts 10 and 11, respectively, and when it is difficult to open the half parts 10 and 11, pull a rope with a hook or the like on the hook hooks 17. You can easily open it with.

A reinforcing member 31 is installed between the leg portion 30 and the bottom portions of the half portions 10 and 11. Further, in order to reinforce the entire bucket 1, a reinforcing member 40 extending in the lateral direction is provided on the front side, the rear side, and the lateral side of the half portions 10 and 11, and a reinforcing member 41 extending in the longitudinal direction is provided on the lateral side. Has been. In the bucket 1 configured as described above, the half portions 10 and 11 are closed, and the notch 20a of the lever 20 is attached to the shaft 2.
After fitting to No. 2, pour the remaining concrete to the appropriate level through the upper opening. When left as it is, when the remaining condensate in the bucket 1 is solidified, the bucket 1 is moved to the disposal site (the bucket 1 may be placed in the disposal site from the beginning), the notch 20a of the lever 20 is removed from the shaft 22 and locked. Is released, and as shown in FIG. 4, the half portions 10 and 11 are pulled up obliquely upward (in the arrow direction). Then, bucket 1
The bottom of the box opens wide, and the solidified concrete 50 inside drops into the ground.

According to this bucket 1, the casters 33 are
Since it is attached, it is easy to move even if the concrete remains inside, and when discarding the solidified concrete, since the half portions 10 and 11 can be pulled up to the side, it is also easy to discard. Therefore, use of this bucket 1 simplifies the disposal of residual concrete at a construction site or the like.
The bucket 1 is an example, and various modifications can be made. For example, although the bucket 1 has a quadrangular shape in plan view, it may have a hexagonal shape in plan view as shown in FIG. In this case, in each corner of the bottom of the half 10 ', 11',
The two legs 35 are extended, and the casters 3 are provided at the intersections thereof.
If the pedestal 32 with 3 is attached, the bucket 1
Is stable.

In particular, the solidified concrete in the bucket 1 tends to adhere to the corners and corners inside the bucket 1 and tends to be caught in the corners and corners so as not to drop from the bucket 1. 1 It is preferable that the inside has a surface as gentle as possible. An example of this is shown in FIGS. In the bucket 1 shown here, the lower portions of the half portions 10 and 11 are curved, and the solidified concrete is easier to separate from the bucket 1 than those shown in FIGS. 1 and 2.

Further, the shapes of the half portions 10 and 11 shown in FIG. 8 in plan view are gentler than those in FIG. 5, so that the solidified concrete does not get caught in the corners as much as possible. Alternatively, as shown in FIG. 10, the shape of the half portions 10 and 11 in plan view may be semicircular, and the lower side may be curved as shown in FIGS. 6 and 7. In this case, since the corners and corners are completely eliminated, the solidified concrete is more likely to drop.

On the other hand, in the bucket 1, the half portion 10,
11 (10 ', 11') are rotatably supported by a single long support shaft 12 which is laid horizontally, but only the fulcrum portions 10a, 11a (10'a, 11'a) at the respective positions. Each of them may be provided with a short support shaft. The solidified concrete formed using the bucket 1 as described above can be recycled as construction waste material. For example, recycled crushed stone by crushing solidified concrete with a crusher [Concrete crushed stone: No. 0 (1 m / m) to 40 m / m]
Make the roadbed material under the asphalt, the foundation of the building,
Used as a base material for the base of a retaining wall (discarded concrete). Conventionally, purchased crushed stones and crushed stones were used for such construction, but now, with the administrative guidance of the Ministry of Construction, recycled crushed stones are used, and the solidified concrete is further processed as described above. By doing so, it can be reused, which leads to the effective use of the remaining concrete.

[0019]

Since the bucket for discarding residual concrete according to claim 1 of the present invention is constructed as described above, not only is it easy to move even when concrete is still contained, but solidified concrete is used. When discarding, one side and the other side can be pulled up to the side, so that the disposal is easy. Therefore, the use of this bucket simplifies the disposal of residual concrete at a construction site or the like.

Further, in the method for discarding residual concrete according to the third aspect, since the bucket according to the first aspect is used, the residual concrete can be easily discarded similarly. Further, the obtained solidified concrete can be crushed to make recycled crushed stone, which can be reused, which is useful for effective utilization of residual concrete.
