 An embodiment embodying the present invention will be described below with reference to FIGS. As shown in FIG. 2, the grating G of this embodiment is laid on a pair of step portions D formed on the upper side of the side groove S having a groove width of a predetermined interval.

As shown in FIGS. 1 and 3, the grating G is composed of a steel main body 1 in the form of a lattice, and a pair of square pipes 2 for raising provided on the bottom surface of the main body 1. The main body 1 includes a pair of plate-shaped end members 3, and a plurality of (11 in this case) plate-shaped main members 4 are provided in the longitudinal direction between the end members 3 in a direction orthogonal to the end members 3. It is welded and fixed at intervals. The pair of main members 4 welded and fixed to both ends of the end member 3 are outer shape main members 4 a and 4 b forming the outer shape of the main body 1. The outer shape of the main body 1 is formed in a rectangular shape by the end members 3 and the outer shape main members 4a and 4b.

Further, as shown in FIG. 4, a notch 5 having a predetermined width W and a predetermined depth D is formed in the central portion of the main member 4 located at the center. A plate-shaped plate 6 as a plate member having a decorative property is fitted in the notch 5. The plate 6 is formed in a rectangular shape having the same length as the width W in the lateral direction and the same length as the length between the main member 4 in the longitudinal direction and the pair of main members 4 adjacent on both sides. The plate 6 is formed to have the same thickness as the depth D of the cutout portion 5, and the city badge 7 is press-molded on the surface thereof. The plate 6 is fitted in the notch 5 so that the city badge 7 faces upward, and the fitting portion and each side end in the longitudinal direction in contact with each main member 4 are arc welded. Are welded together and fixed to the main member 4. Therefore, the plate 6 is buried in the central portion of the main body 1, and the surface thereof and the upper end surface of the main member 4 are flush with each other. Further, the plate 6 has a strength sufficient to withstand a load when a pedestrian walks or a vehicle runs.

As shown in FIGS. 1 and 3, on the upper part of the main member 4, a plurality of (three in this case) substantially rectangular rod-shaped horizontal members 8 are arranged in a direction orthogonal to the main member 4. Welded and fixed so that they are embedded so that they are parallel to each other. The horizontal member 8 fixed at a position that traverses the plate 6 is divided into two parts that are short by the length of the plate 6 and welded and fixed to the main members 4 other than the central main member 4. A plurality of openings 9 are defined by the main member 4 and the lateral member 8. Further, a pair of the square pipes 2 for raising the main body 1 having the same length as the end member 3 are welded to both end portions of the end surface where the plate 6 of the main member 4 is not fixed, on the end member 3 side. It is fixed.

When the grating G configured as described above is used, as shown in FIG. 2, the grating G is laid so that the square pipe 2 is located at each step D of the side groove S. At this time, the upper surface of the side groove S and the upper surface of the main body 1 are flush with each other. In this state, the rainwater that has flowed out during rainfall flows down into the gutter S through each opening 9. At this time, since the plate 6 is embedded and fixed in the central portion of the main body 1, rainwater that enters the opening 9 from the upper surface of the side groove S is not blocked by the plate 6 and drainage performance is reduced. There is no such thing.

When a pedestrian (not shown) walks on the grating G, the surface of the plate 6 and the upper end surface of the main member 4 are flush with each other. There is nothing wrong with it and it does not interfere with walking.

As described above, in the grating G of this embodiment, the plate 6 on which the city badge 7 is press-molded is fitted and fixed to the notch 5 formed in the main member 4, thereby improving water drainage and walking. It can contribute to beautification and decoration of the townscape by improving the appearance without any hindrance.

Further, since the grating G itself has a simple configuration, even if the plate 6 is smaller than the main body 1, it is likely to be caught by the eyes of a pedestrian or the like traveling on a sidewalk. Therefore, it is possible to appeal the pedestrian or the like to the city chapter 7 and to ventilate the attachment to the city chapter 7.

In addition, since the owner is specified by press-molding the city badge 7 on the plate 6, it is possible to prevent theft and prevent personal use as much as possible. .
