Description

  The present invention relates to a gutter on a road, and further to a drainage device for rainwater or the like laid at the entrance of a building.

Recently, drainage grooves have been laid in the office district to prevent rainwater overflowing on the sidewalk from flowing into the building.
This drainage ditch device has a concrete U-shaped drainage groove buried under the road surface, and a rectangular metal intermediate frame that secures a rainwater inflow channel is placed at the upper end opening of the U-shaped drainage ditch. Further, a grating lattice frame made of a plurality of long grating gratings made of stainless steel is placed over the entire length of the metal intermediate frame to finish it almost flush with the road surface.
By the way, this U-shaped drainage groove under the road surface is adopted as wide as possible considering the storage and drainage capacity of rainwater.

Correspondingly, naturally, the grating lattice frame is also widened, and it is possible to increase the number of long grating materials or increase the interval.
Increasing the number and increasing the interval is not suitable for today's society.
In other words, in an office district, it cannot be identified as drainage on a roadway, etc. If the width of the grating lattice frame is widened, women in the office district, especially women in skirts, will be conscious of taking a wide step and will be shunned. .
Further, if the gap between the long grating materials is widened, an unnatural walk that adjusts the stride is performed so that the heel of the high heel does not fall between the long grating materials.

In order to cope with the above-mentioned problems, the applicant has made an invention with the contents shown in Patent Document 1.
That is, a small vertical left and right vertical piece is made upright on the top plate of a metal intermediate frame seated in the upper end opening of the U-shaped drainage groove, and a stainless steel left and right grating long material is welded to the left and right vertical piece. A road surface material such as a tile or a brick is laid and finished between the left and right grating long material and the top plate.
As a result, the U-shaped drainage channel below the road surface maintains the rainwater storage and drainage capacity, and does not increase the width of the grating grid frame on the road surface. So as not to impair the sense of incongruity.
Thus, there is a need to remove the grating grid frame from the grating grid frame when dropping small items such as coins and key holders into the U-shaped drainage groove, and for temporary cleaning.

However, as in Patent Document 2, if the drainage device is close to a roadway that does not take into account the office district at all, the lateral width of the grating grid can be widened, so that it is possible to attach and detach screws with bolts and nuts. This is the reason why the width of the grating lattice frame is narrow and the above Patent Document 1 cannot be identified.
Japanese Patent No. 4811688 JP 2009-97311 A

The U-shaped drainage channel below the road surface maintains the rainwater storage and drainage capacity, does not increase the width of the grating grid on the road surface, and reduces the number of long grating materials as much as possible.
