Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bottom portion of a gutter constructed by a free-gradient type gutter block having an opening for attaching a lid on the upper surface and the whole or a part of the bottom portion being an open type. The present invention relates to a concrete placing machine for placing concrete according to a base concrete and a drainage gradient.

[0002]

2. Description of the Related Art Conventionally, in the construction of gutters of this type, since the whole or a part of the bottom surface of the gutter block is open type, the base concrete for installing the gutter block and the securing of drainage gradient and the opening part It was necessary to pour the invert concrete twice in order to maintain the strength, and the work of piling the concrete twice was complicated.

[0003]

In particular, when placing an invert, inking is performed for adjusting the height of the finished surface in a narrow gutter block having a narrow width, and the leveling and compaction of concrete and the adjustment of the waterway slope are performed. It is a work such as finishing, which is difficult and difficult to be done by a contractor, and there is a demand for a method capable of accurately and easily placing and finishing this concrete.

In order to solve this problem, the applicant previously developed an automatic concrete placing machine such as Japanese Patent Application No. 4-343093. This makes it easier to construct a gutter canal compared to conventional construction, but it is necessary to put a large amount of concrete in the gutter in advance and the concrete hopper will be large, so the site of gutter construction will be large. There was a drawback that it was difficult to work in a curved place.

[0005]

The present invention was developed in order to solve such problems, and short rails are made continuous to form one rail, and this rail is formed in the central longitudinal direction in the gutter. The hopper can be easily moved even if the gutter construction site is curved because one concrete hopper is erected in the gutter, or two concrete hoppers are erected on two rails on both sides inside the gutter by a freely rotating trolley. Further, in a place where the curve is strong, it is possible to easily place concrete on the bottom of the gutter in accordance with the drainage gradient by providing small hoppers continuously.

[0006]

The concrete placing machine for the bottom of the gutter of the present invention is
Concrete is supplied from a concrete hopper that is erected by a trolley to a rail that is installed on the center or on both sides of the buried gutter and that is aligned with the drainage gradient, via a vibrator. Concrete is not only the surface with the drainage slope at the bottom of the gutter,
The gutter block can be filled into the lower space of the installation of the gutter block sufficiently to eliminate double work of base concrete and invert concrete as in the conventional method.

Further, since the concrete hopper is mounted by a trolley that automatically rotates, the hopper can be easily moved even if the rail is curved, and if the curve of the side groove is tight, connect a small hopper. By doing so, it became possible to automatically supply concrete even at the curve.

[0008]

FIG. 1 is a sectional view showing a main part of a concrete placing machine A of the present invention, in which a rail (1) having a groove section or an I section is provided on a side groove B at an upper opening edge (B-1). ), A concrete hopper (suspended to the drainage gradient by a suspending tool suspended in the center of the gutter by a height adjusting tool (2)) and suspended by a trolley (3) on the lower surface of the rail (1) ( 4) is provided and the concrete is placed while moving the concrete hopper while vibrating the concrete in the hopper with the rod-shaped vibrator (5). When the concrete hopper is stopped or moved, concrete C is sequentially supplied to the concrete hopper, which is shaken vertically and horizontally by a bar-shaped vibrator (5), and a leveling plate (6) provided at the rear of the hopper.
While leveling the concrete, add an appropriate amount of concrete to the bottom of the gutter and wrap around the pillow block (7) and every corner of the gutter bottom.

The trolley device (3) for mounting the concrete hopper (4) is loosely mounted on the rotating shaft (16) and can swing freely, and freely moves inside the side groove installed in a straight or curved shape. it can. However, the concrete hopper cannot be lengthened to move the curve,
There is a shortage of concrete capacity. For this reason, when the amount of concrete is low, such as under the reinforcing beam of the gutter, due to the supply state of concrete at the bottom of the gutter, it is necessary to move the hopper while pulling it back, not only in the traveling direction shown in the figure. Therefore, in the case where the concrete hopper is placed inside the gutter installed in a straight line, the concrete hopper can be made long and large, and it is not necessary to pull back the hopper. The finishing of the top surface of the concrete that has been cast into the bottom of the gutter is carried out by moving the finishing machine by vibrating it with a rod-shaped vibrating machine after the completion of pouring and leveling with a placing machine.
