Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a grating supporting device for supporting a grating provided as a lid for covering the upper end of a drain groove inside or outside a building.

[0002]

2. Description of the Related Art Conventionally, a grating which is laid as a cover for covering the upper end of a drain groove depends on the length of the drain groove, but usually a plurality of grooves are used for one drain groove. At present, in order to prevent floating of the grating from above and prevent theft, etc., adjacent gratings are connected by bolts and nuts.

However, in the work of connecting adjacent gratings with, for example, bolts and nuts, the main bars, which are the constituent materials of the gratings located at the ends, are brought close to each other, the bolts are inserted into both main bars, and the nuts are attached to the bolts. Although it is carried out by screwing, it is difficult to insert the bolt into the main bar and screw the nut into the bolt in a narrow space inside the main bar, and there is a problem that skill is required. In addition, the bolts and nuts must be attached and detached every time maintenance such as cleaning of the drainage groove is performed, which causes a problem that the maintenance is very troublesome.

The engaging plate members 11 and 12 projecting from a and 8b are provided in a state of being divided into two, respectively, but may be provided in a continuous state. Further, the side plate portions 8a, 8b of the main body 8 are
Is connected in the length direction of the main body 8, but it may be cut out in the middle to be divided. Furthermore, a plurality of drain holes may be provided in the horizontal plate portion 8c of the main body 8 so that the water that has entered the main body 8 is dropped into the drain groove 2.

Next, the second embodiment shown in FIGS. 7 and 8 will be described. In this second embodiment, a plate portion 8f which rises at a right angle from the widthwise center of the horizontal plate portion 8c of the main body 8 is provided. The slits 9 and 10 are formed at the lower end of the portion 8f,
Engaging plate bodies 11 and 12 are fitted in the slits 9 and 10, and the end portions of the grating adjacent to both surfaces of the plate portion 8f are arranged between the outer end plate portions 11c and 12c of the engaging plate bodies 11 and 12. Projecting pieces 8d and 8e sandwiched between are provided. The other structure is the same as that of the first embodiment and functions similarly to the first embodiment.

Next, the third embodiment shown in FIGS. 9 and 10 will be described. In this embodiment, both ends of the main body 8 in the longitudinal direction are plate portions 8g which are perpendicular to the side plate portions 8a and 8b and are oriented in the vertical direction. Is provided, a screw hole 22 is formed in the plate portion 8g, and a bolt 23 is screwed into the screw hole 22 so that the tip of the screw hole 22 protrudes horizontally from the plate portion 8g. When the supporting device 7 is set on the receiving portion 3, the tip of the bolt 23 is configured to be in pressure contact with the rising wall 3a of the receiving portion 3 of the drain groove 2, whereby the supporting device from the drain groove 2 is configured. 7. By extension, theft of the grating 1 can be prevented more reliably.

[0016]

As described above, according to the present invention, the supporting device is positioned between the adjacent gratings, and the outer end plate portion of the engaging plate body provided on the main body is engaged with the inside of the adjacent grating end portions. And, by sandwiching the end portion of the adjacent grating between the projecting portion provided on the main body and the outer end plate portion of the engaging plate body, the play between the adjacent gratings is eliminated,
The grating can be firmly attached to the drain. This work may be performed between gratings, and requires more skill than the conventional work of inserting a bolt into a main bar in a narrow space inside the main bar and screwing a nut onto the bolt as in the conventional case. It is easy to perform, and there is no major difficulty in maintenance, and workability can be improved.
