DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a metal cover which is installed so as to cover an opening of a side groove called grating.

[0002]

2. Description of the Related Art As shown in FIG. 4, a grating (metal cover) 40 is provided at an opening 31 of a side groove 30 such as a drainage channel so as to be opened and closed for inspection and cleaning. The grating 40 is directly mounted on a horizontal lid contact surface 33 formed on the upper surface of the side wall 32 of the side groove 30 as shown. The grating 40 may be placed via a receiving frame (not shown). Reference numeral 35 in the figure indicates the groove bottom of the side groove 30.

In recent years, as shown in FIG.
The entire surface of the contact surface portion 53 for the lid on the upper surface of the side wall 52 of the side groove 50 is formed into a curved surface, and the contact surface portion 61 (side surface in the side groove direction) of the lid 60 is formed with respect to the contact surface portion 53 for the curved surface of the side groove 50. A configuration has been proposed in which the side grooves 50 and the lid 60 are closely contacted with no gap between them. With this configuration, the lid 60 is stably mounted on the side groove 50 due to the characteristic of the curved surface, and noise due to vibration when the vehicle or the like passes is reduced, and at the same time, the side groove 50 and the lid 60 are damaged. Can also be prevented. In the drawings, reference numeral 51 denotes a side groove 5.
An opening of 0 and 55 also represent a groove bottom.

However, the contact surface 6 of the lid 60
1 is formed into a curved surface, if the lid 60 is made of a metal grating, the curved contact surface 61 is replaced with the lid 60.
Forming it on the side surface is inconvenient in design and manufacturing, and is also disadvantageous in terms of cost. When laying a paving material such as interlocking around the side groove 50, the surface of the lid 60 needs to be installed higher than the upper surface of the side wall 52 of the side groove 50 so as to be flush with the surface of the paving material. is there. In such a case, it is difficult to adjust the height of the lid 60 having the above-described configuration in design.

[0005]

DISCLOSURE OF THE INVENTION The present invention has been proposed in view of such circumstances, and has a simple structure and can be stably installed in an opening of a side groove economically.
Moreover, it is intended to provide a grating that can be easily adjusted in height.

[0006]

That is, the present invention provides:
A contact surface member made of a metal pipe having a curved surface similar to the curved contact surface portion on the upper surface of the side wall of the side groove in which the lid body is disposed, at least in the direction of the lower surface side groove of the lid body where the outer frame is made of metal. The grating according to the present invention is characterized in that the stopper is fixedly provided, and a stopper member engaged with an inner side wall of the side groove is fixed inside the contact surface member.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the accompanying drawings. FIG. 1 is a perspective view showing a grating according to an embodiment of the present invention, FIG. 2 is a sectional view showing a state where the grating shown in FIG. 1 is installed in an opening of a side groove, and FIG.
It is sectional drawing which shows the contact surface member of grating.

The grating 10 of the present invention shown in FIGS. 1 and 2 is installed as a gutter cover for inspection or drainage so as to cover the opening 21 of the gutter 20 as shown in FIG. 11, contact surface member 15 and stopper member 1
7 are provided. Reference numeral 22 in the figure denotes a side wall of the side groove 20, 2
Reference numeral 3 denotes a curved contact surface formed on the upper surface of the side wall 22, and reference numeral 24 denotes an inner surface of the side wall 22. The illustrated side groove 20 has U
Although a U-shaped groove is used, an inverted U-shaped groove may be used.

The lid body 11 is a main part of the grating 10 which covers the opening 21 of the side groove 20 so as to be openable and closable. In this example, as shown in FIG. Outer frame 12 made of metal such as stainless steel or a casting, and a crossbar 13 bridged within the outer frame 12, and a twist bar disposed on the upper surface of the crossbar 13 at right angles to the crosswise direction of the crossbar 13. 14

The contact surface members 15 are fixedly provided on both sides of the lower surface of the lid body 11 in the side groove direction, and are placed on the curved contact surface portion 23 on the upper surface of the side wall 22 of the side groove 20. The contact surface member 15 has a curved contact surface portion 23 of the side groove 20 on the outer surface side.
And a metal pipe having a curved surface 16 similar to the above. This contact surface member 15 is formed by molding a straight tubular metal pipe into a predetermined irregular cross-sectional shape by known drawing or the like. The contact surface member 15 is fixed to the lower side of the lid body 11 by welding or the like.

When the grating 10 on which the contact surface member 15 is provided is placed on the curved contact surface portion 23 on the upper surface of the side wall 22 of the side groove 20, as shown in FIG. When the curved contact surface portion 23 of the side groove 20 is in close contact, the grating 10 is attached to the side groove 2.
0 is stably mounted on the upper surface of the side wall 22 to reduce vibration when a vehicle or the like passes, and to prevent noise or damage to the grating 10 and the side groove 20.

The contact surface member 15 also serves as a raising material for defining the surface height of the grating 10.
In this example, the surface of the grating 10 (the lid body 11) is adjusted to be the same height as the upper surface of the side wall 22 of the side groove 20. Although not shown here, the side grooves 2
When laying a paving material such as interlocking around zero, the surface of the grating 10 needs to be installed higher than the upper surface of the side wall 22 of the side groove 20 so as to be flush with the surface of the paving material. Even in such a case, unlike the prior art in which the side surface in the side groove direction of the lid 60 is a curved contact surface portion 61 (see FIG. 5), the contact member 15 is not used.
It is easy and quick to respond simply by adjusting the height of the device, which is advantageous in design and manufacturing.

The stopper member 17 is a portion fixed to the inside of the contact surface member 15 and engaged with the inside 24 of the side wall 22 of the side groove 20. The stopper members 17 are made of a substantially L-shaped plate material such as metal, and are fixed to a predetermined position inside the contact surface member 15 by welding or the like. In this example, a total of four stopper members 17 are arranged below the bar 13 at the outermost side (near the outer frame 12) of the lid body 11, and are provided not only on the inside of the contact surface member 15 but also on the lower surface of the bar 13 Are also fixed by welding or the like.

The provision of the stopper member 17 prevents a problem that one side of the grating 10 falls into the side groove 20 during the operation,
Since it can be placed on the curved contact surface portion 23 on the upper surface of the side wall 22, the working efficiency is improved. Further, even after the mounting, the strength of the contact surface member 15, particularly, the joining property between the lid body 11 and the contact surface member 15 is reinforced, and
Can be prevented from being displaced.

[0015]

As shown and described above, according to the grating of the present invention, since the contact surface member similar to the curved surface contact surface portion of the side groove is provided in the direction of the lower surface side groove of the lid body, it is extremely simple. With a simple structure, it can be stably installed in the opening of the gutter, and can improve noise problems and safety problems such as breakage of the lid or the gutter, and are economical. Further, even when it is necessary to set the height higher than the upper surface of the side wall of the side groove, the height can be easily adjusted only by changing the height of the contact surface member, which is advantageous in design and manufacturing.
