Abstract

PURPOSE:To make it possible to install a low weight and high rigidity cover in a stabilized manner by inserting the side of a stopper plate vertically installed under both ends of a rectangular-shaped steel plate main body which is slightly wider the width of a road ditch along the inner wall of the ditch. CONSTITUTION:Stopper plates 2, which are slightly narrower than the with of a main body 1 and substantially equivalent to the cross section of a ditch are installed vertically and as opposed below both ends of a main body 1 on either side fabricated with a rectangular-shaped steel plate which is slightly wider than the width of a road ditch and uneven-surfaced on the top on the opposite side. The lower ends of the stopper plates 2 are set to be slightly higher than a normal water level in the ditch. When the main body is inserted and installed continuously along the inner wall in edges 3 of both ends of the stopper plates 2, this construction makes it possible to exert resistance to curved deformation in the front and rear direction of the main body 1 and in the longitudinal direction of the ditch or either direction, thereby stabilizing the cover.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a groove cover for covering a groove provided along a road, and more particularly to a groove cover using a steel plate.

[0002]

2. Description of the Related Art Generally, a road is provided with a gutter for draining rainwater and the like, which is covered with a gutter lid so that pedestrians and vehicles do not fall into the gutter. .

Usually, the groove lid is often made of concrete, but since it is heavy and cannot be easily attached / detached, when it is necessary to remove the groove lid for cleaning the inside of the gutter, etc. A steel plate groove lid that can be made lighter is used.

FIG. 5 is a bottom perspective view showing a conventional example of a steel plate groove lid, in which a pair of left and right angles (102) are formed in the longitudinal direction on both edges of the bottom surface of a rectangular steel plate body (101). It is welded parallel to.

The main body (101) is often made of a steel plate having a non-slip surface.

The width of the main body (101) is made wider than the width of the side groove to be installed, and the distance between the pair of left and right angles (102) is set to be slightly smaller than the facing distance between the inner walls of the side grooves.

FIG. 6 is a cross-sectional view showing a state in which a conventional steel plate groove lid is installed in the gutter, and in the gutter (104) provided along the road (103) or across the road, Body
Both edges of (101) are placed on the upper part of the inner wall (105) of the side groove (104), and a pair of left and right angles (102) are fitted between both inner walls (105).

[0008]

In the conventional groove lid made of steel plate, one edge of the main body (101) is disengaged from the inner wall (105) of the gutter as shown by a chain line in FIG. ) It may fall within.

For example, when an automobile passes over the groove lid at a high speed and a considerable load is momentarily applied to the groove lid, the steel plate body (101) is temporarily moved downward. After being bent to, the elasticity may cause it to rapidly return to a flat state and bounce up from the installed position. If the degree of bounce up is large, the groove lid will fall into the gutter (104).

In order to prevent this, the steel plate constituting the main body (101) may be thickened to increase the strength, but the weight of the groove lid becomes large, which makes it inconvenient to handle and it is difficult to handle on the road surface. On the other hand, a large step is formed, which causes inconvenience such as a pedestrian tripping.

An object of the present invention is to provide a gutter lid for a road gutter that has solved these disadvantages.

[0012]

[Means for Solving the Problems] The present invention for achieving the above object is configured as follows.

A groove lid main body which is rectangular and has opposite front and rear edges placed on the upper edges of both inner walls of the road side groove to cover the groove.
A groove cover for a road groove, which has a pair of left and right locking plates that have a shape that substantially matches the cross section of the groove on the lower surfaces of the left and right edges of the groove cover body and that are vertically installed so as to be inserted into the groove. .

It is desirable that both side edges of the locking plate closely face both inner walls of the groove and that the lower edge of the locking plate be separated from the bottom surface of the groove.

Filling members for filling the gaps between the side walls of the opposing grooves may be mounted on both side edges of the locking plate,
The filling member may be a plastic member having a U-shaped cross section.

[0016]

Operation: By vertically suspending locking plates having a shape that substantially matches the cross-sectional shape of the groove on both edges of the main body of the groove lid and inserting it into the groove, the groove lid is stably placed at a predetermined position on the groove. Can hold

The rigidity of the main body is increased by suspending the locking plates at both edges.

The groove lid can be held more stably by mounting a filling member on the side edge of the locking plate to fill the gap with the inner wall of the opposite side groove.

[0019]

FIG. 1 is a perspective view showing an embodiment of the groove lid of the present invention.

The groove lid is provided with locking plates (2), which extend in the front-rear direction, hanging downward at both left and right ends of a main body (1) made of a steel plate having an uneven surface.

The width of the main body (1) in the front-rear direction intersecting the groove is set larger than the width of the groove to be installed, and the locking plate
The width between both side edges (3) of (2) is set to be slightly smaller than the width of the groove so that the locking plate (2) can be inserted into the groove.

FIG. 2 is a sectional view showing a state in which the groove lid is installed in the groove. Both edges of the main body (1) are placed on the inner walls (6) of the groove (5) and locked. Both side edges (3) of the plate (2) closely face and face the inner wall (6).

The lower edge of the locking plate (2) has a bottom surface (7) of the groove (5).
Is set at a position away from. That is, the locking plate
The dimension of (2) in the height direction is selected to be smaller than the depth of the groove (5).

The distance between the lower edge of the locking plate (2) and the bottom surface (7) of the groove is such that the lower edge is higher than the water surface in the normal amount of the drainage (8) flowing in the groove. It is selected so as not to obstruct the flow.

In the groove lid of the above-mentioned embodiment, since the locking plates (2) perpendicular to the surface of the body (1) are connected to both the left and right ends of the body (1), the body (1) has a groove. It is possible to construct a groove lid with sufficient strength by using a relatively thin steel plate that has a high resistance against the bending in the front-back direction that hangs down.

On the other hand, as shown in FIG. 3, when the main body (1) is curved in the lengthwise direction of the groove, both front and rear edges of the main body (1) are placed on the upper side walls of the groove. Even if a load (W) is applied, it does not normally bend, but when the side wall is broken, it also bends in this direction.

In this case, the locking plates (2) vertically provided at the left and right ends are urged outward and press the locking plates of the groove lids installed adjacent to each other. A reaction force (R) against the pressing force (S) is generated from the locking plate of the adjacent groove lid, and a force resisting the bending deformation of the main body (1) is generated. It is possible to form a groove lid having various strengths.

The method of producing the groove lid shown in FIGS. 1 and 2 is as follows. One end of a rectangular steel plate is bent to form a U-shape, and both U-shaped sleeve plates are locked by a locking plate (2 ), Both side edges thereof may be appropriately cut off to have a size suitable for the width of a desired side groove.

Alternatively, separately formed locking plates (2) may be welded to the left and right ends of the steel plate of the main body (1).

The groove lid of the present invention is constructed as described above, but the side edge (3) of the locking plate (2) and the side wall of the side groove.
If the distance from (6) is large, the margin for the mounting position of the groove lid in the front-rear direction becomes too large, and the groove lid rattles and becomes unstable, or the direction of the connected groove lid is disturbed. However, there are inconveniences such as an unsightly appearance.

FIG. 4 is a partial perspective view showing a means for preventing such an inconvenience, and a locking plate vertically provided on the main body (1).
The filling member (10) is auxiliary attached to the side edge (3) of (2).

The filling member (10) is made of an appropriate plastic material in the shape of a rod having a U-shaped cross section, and has a groove portion in the U-shaped shape.
Fit (11) on the side edge (3) of the locking plate (2).

The thickness of the bottom surface of the U-shaped groove (11) of the filling member (10) and the back surface of the member is determined by the side edge (3) of the locking plate (2) and the inner wall of the groove.
By matching the size of the gap with (6), when mounted in the groove, the gap between the locking plate (2) and the inner wall (6) of the groove is closed, and unstable movement of the groove lid is prevented. In addition, a large number of groove lids can be aligned and mounted under certain conditions.

[0034]

【The invention's effect】

(a) It is possible to construct a groove lid having sufficient strength by using a relatively thin steel plate.

(B) Since the locking plate having a shape suitable for the cross-sectional shape of the groove is inserted and installed in the groove, it can be installed stably.

(C) When a large number of groove lids are installed in series, the installation positions of the individual groove lids are uniform, so that they can be easily aligned.
