Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gutter block which is provided at a boundary between a sidewalk and a road to collect water.

[0002]

2. Description of the Related Art In a conventional gutter block, as shown in FIG. 3 (A), a curb block 72 is provided at a boundary portion separating a sidewalk 70 and a roadway 71.
It is located at a higher level. Further, a U-shaped block 74 having a water collecting groove 73 for draining the pedestrian road is provided along the curb block 72 at an end on the side of the road adjacent to the curb block 72.

The white line on the roadside is 500 from the curb to the roadside.
The conventional U-shaped block 7 is pulled to a position of mm.
Since 4 having a width of about 400 mm from the curb is used, a white line may be drawn near the gutter, and a white line may be drawn on the gutter block, which is difficult to visually recognize.

Therefore, as shown in FIG. 3B, in Registered Utility Model No. 3027407, the bottom of the curbstone 75 is entirely placed on the top surface of the gutter member 76, and the width of the gutter opening is set. Gutter block 7 with a diameter of about 250 mm
7 is disclosed. With such a configuration, the white line is separated from the side groove block 77, so that the white line can be easily visually recognized.

[0005]

However, in the conventional gutter block 77, the width of the opening is made smaller in order to make the overall width narrower, so that not only the water collecting ability is lowered but also the cleaning work is performed. There is a problem that it will be difficult. In addition, it is necessary to newly create and use a gutter lid or grating (lattice lid) to be attached to the narrow opening, which is more expensive than standard gutter lids and gratings. ing.

On the other hand, as shown in FIG.
Although the curbstone structure 79 in which the curbstone member 80 is fixed to the central upper part of the grating 78 of the standard product is disclosed in Japanese Patent Publication No. 00-282560, since the curbstone structure 79 is a structure that can flow from both sides of the curbstone member 80, The use range is limited, and it is not possible to form a sidewalk having a step, for example. Further, since the gap above the grating 78 is small, the curb member 80 and the grating 78 have to be fixed from the back side in an upright state before being installed in the gutter, and workability is poor. Further, even when it is desired to remove only the grating 78 after the curbstone structure 79 is installed, it is necessary to integrally handle the curbstone member 80 and the grating 78, and there is a problem in that workability is deteriorated due to the large weight.

[0007] Therefore, the problem to be solved by the present invention is
Provide a gutter block that is easy to handle because the width of the gutter is narrowed while keeping the drainage performance and cleaning work performance, and the overall shape is made compact and the water passage lid can be handled separately from the curb member. Especially.

[0008]

In order to solve the above problems, a gutter block of the present invention is provided with side plate portions on both sides of a bottom plate portion, and a ceiling plate portion for connecting the both side plate portions is provided on a ceiling surface, A gutter having an underdrain block in which an opening communicating with the inside and outside is formed in the top plate portion, a water passage lid detachably fixed to the opening portion, and a curb block provided on the top plate portion. In the block, on the water lid,
A curb member in which one side portion is fixed to one of the side plate portions, and an intermediate portion and the other side portion are arranged above the water passage cover with a gap is continuously provided in the curb block.

The water passage lid is a lid having an opening and having a function of causing drainage to flow downward. For example, a grating made of a steel material in a lattice shape can be used.
Since the middle portion and the other side portion of the curb member are arranged above the water passage cover with a gap, rainwater or the like can be guided from the other side portion to the entire surface of the water passage cover and drained. Further, since one side portion of the curb member is fixed to one of the side plate portions, the height of the road surface connected to the one side can be freely set.

The curb member is composed of a bent metal plate,
It is also possible to detachably fix to the side plate portion from above together with one mounting portion of the water passage lid. Since the curb member is made of a metal plate, it can be made lightweight and easy to handle, and since it can be attached to the side plate portion together with one mounting portion of the water passage lid, the curb member, the water passage cover,
The side plate portion can be separated from each other. Furthermore, since it is detachable from the upper side, the curb member can be fixed after fixing the water passage cover, and the assembly becomes easy. It is also possible to have a structure in which only the water passage lid is independently attached and detached while the curb member is fixed.

The curb member may be made of resin concrete and integrally fixed to the upper part of the underdrain type block. Since the curb member is fixed to the upper part of the underdrain type block, only the water passage lid can be independently attached and detached.

It is also possible to form one or a plurality of through holes for collecting water which vertically penetrate the top plate portion. The through hole is formed so as to avoid the opening, and has a circular shape, a rectangular shape, a slit shape, or another shape. By providing the through hole, drainage from the opening can be assisted.

It is also possible to form the through hole for collecting water in a slit shape which divides the top plate portion into two in the longitudinal direction. By forming the slit shape, drainage can be evenly assisted along the longitudinal direction.

It is also possible to provide the top plate portion with a positioning projection which projects from the wall portion on the other side adjacent to the through hole toward one side and positions the curb block laterally. Since the positioning projections are provided, it is possible to accurately perform the positioning by reducing the portion contacting the curb block. Further, it is possible to prevent the through hole from being blocked by the curb block.

Side plates are provided on both sides of the bottom plate, and a ceiling plate connecting the both side plates is provided on the ceiling surface. The ceiling plate has a through hole for dividing the ceiling plate in two in the longitudinal direction. In a gutter block having an underdrain type block formed along with, and a curb block provided on the top plate portion,
The top plate portion is provided with a positioning protrusion that projects from one wall portion adjacent to the through hole toward the opposite wall portion to perform lateral positioning of the curb block.
With this configuration, it is possible to reliably position the curb block with the positioning protrusions, to secure the opening width of the through hole, and to secure the drainage performance.

It is also possible to integrally form the curb block on the top plate portion. With such a configuration, the number of parts can be reduced and a product can be accurately formed.
