Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a gutter lid device such as a gutter for drainage, a transverse gutter, or a collecting basin installed on a road, a parking lot, a plaza, a park, or the like.

[0002]

[Prior art]

 Conventionally, as seen in Japanese Utility Model Publication No. 4-4270, etc., a grid-shaped groove cover is fitted to a receiving frame member having an L-shaped section at the upper surface opening of a drainage gutter, a transverse groove, or a water collecting basin. Although a groove cover device is provided so that they can be supported together, in this type of conventional groove cover device, the groove cover is entirely intimately intimately contacted with the inner surface of the bottom plate of the receiving frame material, so that the drainage is poor and the freeze There was a problem that it was difficult to open and close the groove lid due to rust and rust.

[0003]

[Problems to be solved by the device]

 The problem to be solved by the present invention is to solve the above-mentioned problems and to prevent the groove lid from being completely intimately contacted with the inner surface of the bottom plate of the receiving frame material, and to open and close the groove lid with rust and rust. It is to provide a groove lid device that does not become difficult.

[0004]

[Means for Solving the Problems]

 The groove lid device of the present invention, which has solved the above-mentioned problems, is a groove lid device in which a groove lid is fitted and supported on a receiving frame material having an L-shaped cross section, and a vertical plate portion of the receiving frame material is provided on the inner surface of the receiving frame material. The narrow groove extending from the upper edge to the outer edge of the bottom plate is arranged at a required interval to improve drainage between the receiving frame and the groove lid. The interior angle of the L-shaped frame member may be 90 °, but in order to make it easier for water that reaches the bottom plate to be drained, the L-shaped frame member should have an internal angle slightly larger than 90 °. You can leave it. In addition, as a measure against noise, packing may be inserted between the bottom plate of the receiving frame and the groove lid. There will be no hindrance.

[0005]

[Action]

 If such a groove lid is provided in the side groove, the transverse groove, or the upper opening of the water collecting basin, rainwater can be drained from the gap between the lateral members of each groove lid, as in the conventional groove lid device of this kind. However, since the receiving frame material that is arranged on the inner surface of the receiving frame material at a required interval has a narrow groove that extends from the upper edge of the vertical plate portion to the outer edge of the bottom plate portion, between the receiving frame material and the groove lid. The infiltrated rainwater is properly discharged from the outer edge of the bottom plate through the narrow groove.

[0006]

【Example】

 Hereinafter, the present invention will be described in detail with reference to the embodiment shown in FIG. Reference numeral 1 denotes a receiving frame member having an L-shaped cross section, which is provided at a side groove, a transverse groove, or an opening edge of an upper surface of a water collecting basin, and 11 denotes a groove lid fitted and supported by the receiving frame member 1. The receiving frame member 1 has a large number of narrow grooves 2 arranged at required intervals so as to reach from the upper edge of the vertical plate portion 1a to the outer edge of the bottom plate portion 1b. Further, the receiving frame member 1 of the embodiment has a bottom plate portion. In order to make it easier for the reached water to be discharged, it is set to about 92 ° to 97 °, which is slightly larger than 90 °, but there is no particular problem if it is 90 °.

On the other hand, the groove lid 11 fitted and supported by the receiving frame member 1 has a horizontal member 14 stretched over the vertical girder member 3 which is a main member composed of a side plate 12 made of strip steel and a vertical girder member 13. Although it is a well-known type in which leg portions 15 made of square pipes are formed on the lower surfaces of both sides, a packing 16 interposed between the bottom plate portion 1b of the receiving frame member 1 and the groove lid 11 is attached to the bottom surface of the leg portions 15. There is.

The thus constructed device is provided at a side groove, a transverse groove (not shown) or the upper edge of the opening of the water collecting basin, and when used in the same manner as a conventional groove lid device of this kind, the lateral member 14 of the groove lid 11 is provided. , The rainwater will be properly discharged from the gap between them, and the inner wall of the receiving frame member 1 has a narrow groove 2 extending from the upper edge of the vertical plate portion 1a to the outer edge of the bottom plate portion 1b. Since the rainwater that has entered between the receiving frame member 1 and the groove lid 11 flows down through the narrow groove 2 to the outer edge of the bottom plate portion 1b accurately and is discharged into the groove, the receiving frame member 1 is provided. The contact area between the groove lid 11 and the groove lid 11 is significantly reduced, and the water pool is almost completely eliminated. There is no difficulty in opening and closing the lid. Moreover, since the large number of narrow grooves 2 increase the strength of the receiving frame member 1 due to the rib effect, the receiving frame member 1 can be thinned.

Further, if the inner angle of the receiving frame member 1 having an L-shaped cross section is set to be slightly larger than 90 ° as described in the embodiment, the bottom plate portion 1b is inclined downward and the water is discharged more smoothly. Therefore, it is more preferable. Further, when the packing 15 is interposed between the bottom plate portion 1b of the receiving frame material 1 and the groove lid 11, water can flow down due to the narrow groove 2 on the inner surface of the receiving frame material 1, so that no noise is caused in drainage. The prevention effect can be expected.

[0010]

[Effect of device]

 As will be apparent from the above description, the present invention provides a groove lid device in which a groove lid is fitted and supported by a receiving frame material having an L-shaped cross section, from the upper edge of the vertical plate portion to the outer edge of the bottom plate portion on the inner surface of the receiving frame material. Since a large number of narrow grooves to reach are arranged at the required intervals, the rain cover is not completely intimately contacted with the inner surface of the bottom plate of the receiving frame material, but rainwater is properly discharged through the narrow grooves, and the receiving frame material and the groove cover are properly discharged. There is an advantage that water can be accumulated in the meantime and frozen or rusted to make it difficult to open and close the groove lid. Therefore, the present invention is of great practical value as a groove lid device that solves the conventional problems.
