<First Embodiment>
The configuration of the grating 1 will be described with reference to FIGS. 1 to 6. In FIG. 2, a cross-shaped pattern is attached so that the veneer portion 5 described later becomes clear, but this pattern is not actually provided (the same applies to FIG. 11).
The grating 1 is for closing the upper opening of a gutter such as a road, and is made entirely of iron material. As shown in FIG. 1, the grating 1 includes a pair of end angles 3 hung on the upper left and right upper edges of the gutter W, and a plurality of main bars 2 provided so as to be erected between the two end angles 3. A center bar 4 is provided in which the center of the main bar 2 is provided in the length direction of the grating 1. As shown in FIG. 4, the end angle 3 is formed by bending an elongated iron plate material into an L-shaped cross section. In general grating, the width dimension L and the height dimension M of the end angle are configured to be substantially the same. However, in the grating 1, the width dimension L is made longer than the height dimension M in order to adjust the rattling of the wide gutter W in the width direction (L> M).

At both front and rear ends of the grating 1, the assembly plate portion 5 is welded and fixed so that the left and right end angles 3 are erected on the lower surface side of the main bar 2. The veneer portion 5 has a size that closes between the pair of front and rear main bars 2. Bolt insertion holes 12 through which the screw shaft portions of the bolts 7 can be inserted are opened in pairs (4 in total) near the left and right ends of the assembly plate portion 5. Width variable members 10 are attached to the left and right sides of the lower surface of the veneer portion 5. The width variable member 10 is formed by bending a plate material cut into a predetermined shape. The width variable member 10 is provided with a bottom plate portion 14, a side edge contact portion 11 that is bent vertically upward from the bottom plate portion 14, and a slide operating portion 6 that is similarly bent vertically upward (FIG. 5). reference). The base portion of the slide operation portion 6 is a horizontal projecting portion 15 extending horizontally from the bottom plate portion 14. Further, in the center of the bottom plate portion 14, a slide groove 13 is opened in the length direction of the main bar 2 (the left-right width direction of the grating 1). The diameter of the slide groove 13 is formed to be larger than the diameter of the screw shaft portion of the bolt 7.
Further, a rectangular plate-shaped fixing plate 8 is attached to the lower surface side of the width variable member 10. The fixing plate 8 is provided with two bolt assembly holes 9 provided with female threads to which the male threaded portion of the bolt 7 can be turned. Further, a nut 16 to which the bolt 7 can be turned is provided on the lower surface side of the fixing plate 8.

Next, the operation and effect of the present embodiment will be described with reference to FIGS. 7 to 10.
Prior to closing the gutter W with the grating 1, the variable width member 10 and the fixing plate 8 are placed on the lower surface side of the assembly plate portion 5 in an overlapping manner. At this time, the positions of the bolt insertion hole 12, the slide groove 13, and the bolt assembly hole 9 are aligned. Here, the male screw portion of the bolt 7 is passed through the bolt insertion hole 12 and the slide groove 13 and lightly turned around the bolt assembly hole 9 and the nut 16 (temporary assembly state: see FIG. 7). In this temporarily assembled state, the width variable member 10 operates the slide operation portion 6 or the horizontal projecting portion 15 with the two bolts 7 inserted through the slide groove 13, whereby FIG. 7A is shown. It is possible to slide in the directions of the arrows P and Q in the middle. That is, as shown in FIGS. 7 (A) and 7 (B), the side edge contact portion of the width variable member 10 for a predetermined length (specifically, according to the length of the slide groove 13). The position of 11 can be displaced laterally.

Next, as shown in FIG. 8, the temporarily assembled grating 1 is covered so as to close the upper surface opening of the gutter W. Here, with respect to the left and right width variable members 10 from above the main bar 2, the slide operation portion 6 (or the horizontal protrusion portion 15) is operated with a finger or a jig (for example, a screwdriver) to slide and move in the width direction. , The side edge contact portion 11 is set to hit the side edge X of the side groove W. At this position, turn the bolt 7 completely with a screwdriver to bring it into the final assembly state. In this assembled state, the grating 1 can be installed in the gutter W without rattling (see FIG. 9).
In the grating 1 of the present embodiment, as shown in FIG. 10, the variable width member 10 can be attached upside down. In this case, the width variable member 10 is slid and moved in the left-right width direction of the grating 1 with the side edge contact portion 11 hanging downward. Depending on the state of the gutter W and the side edge X, this form can also be used. In this case, the horizontal projecting portion 15 is used for the slide movement of the width length variable member 10.

As described above, according to the present embodiment, even if there is a slight error in the groove width of the gutter W, it is possible to provide the grating 1 capable of absorbing the error.
Further, the bolt assembly hole 9 is integrally formed with the fixing plate 8. Therefore, as compared with the case where the nut is separately provided, it is possible to avoid a situation in which the nut falls when the bolt 7 is turned.
Further, after the grating 1 is placed on the gutter W, the position of the width length variable member 10 can be determined from the space above the grating 1 by using the slide operation unit 6, so that the operability is improved.
Further, since the width length variable member 10 is provided on both sides of the left and right end angles 3 and 3, the fixing position of the grating 1 is set to the gutter W as compared with the case where the width length variable member 10 is provided only on one side. Can be placed near the center. Therefore, the stability at the time of installation becomes better.
Further, since the width length variable member 10 is provided on both the front end and the rear end of the end angle 3, the grating 1 can be positioned on both the front and rear sides of the end angles 3 and 3.
