Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sealing member for a lid which covers an opening of a side groove provided on a road shoulder or the like or a sewer groove (hereinafter simply referred to as a sewer groove) provided so as to cross a road.

[0002]

2. Description of the Related Art Conventionally, there are sewage gutters for draining rainwater and the like, in which an opening on the upper surface is covered with a lid made of concrete or a grid-like lid called grating. In addition, in the sewer groove with the opening covered with a lid, the size of the lid is slightly smaller than the size of the opening of the sewer groove to facilitate work during construction. Usually, there is a gap between the lid and the lid.

[0003]

Therefore, when a vehicle such as an automobile passes on the lid, the lid vibrates and causes noise, or cracks occur in the concrete drainage gutter and the lid, resulting in an early stage. There is a problem such as being damaged. When rainwater, etc., flows into the sewer ditch, the sediment on the road surface flows into the gap together with the rainwater, so the sand and sand invade between the sewer ditch and the lid, causing the lid to float up and prevent the passage of vehicles. There were also problems such as hindrance. The present invention has been made to improve such a problem, and a sealing member for a lid body in a sewer groove that absorbs vibration of the lid body and prevents dirt and the like from entering between the sewer groove and the lid body. It is intended to be provided.

[0004]

In order to achieve the above-mentioned object, the present invention has a lid body fitted in the opening to cover both sides of the lid in a sewer groove. An upright portion provided along a vertical portion of the side plate, a seal / buffer portion that is continuously provided on the upper portion of the upright portion and is bendable along the lower surface of the horizontal portion of the side plate, and is horizontal from the outer surface of the upright portion. A seal member main body composed of a rib protruding in a direction is formed of an elastic body, and the seal / buffer portion of the seal member main body is located between the upper surface of the sewage groove and the lid body, and the tip of the rib. Is interposed between the sewer groove and the lid so as to contact the inner surface of the opening of the sewer groove.
In addition, the seal-cum-buffer section connected to the upright section is made thinner than the upright section so that the seal-cum-buffer section can be easily bent.
In the upright portion of the seal member main body, a plurality of mounting recesses for fixing the upright portion to the side plate of the lid body by the fixing means are formed at intervals in the longitudinal direction, and a notch is formed in a part of the rib that matches the mounting recess. Is formed.

[0005]

[Operation] With the above structure, the seal / buffer unit seals the gap between the sewer groove and the lid, so that it is possible to prevent rainwater and dirt from entering between the sewer groove and the lid. Even if a vehicle or the like passes over the lid and vibration is generated in the lid, the buffer section absorbs the vibration, so that noise is not generated and the sewer groove and the lid are not damaged by the vibration.
In addition, the rib tip is in contact with the inner side surface of the opening of the sewage groove, so that the lateral displacement of the lid can be regulated, and the sealing and cushioning part can be made thinner than the upright part, so that it easily bends along the side plate surface of the lid. Become. Further, by attaching the seal member main body to the lid body in advance by the fixing means, it is possible to easily cover the sewage groove with the lid body, and there is no fear of the seal member body slipping or falling off after construction.

FIG. 5 is a perspective view, and FIG. 5 is an enlarged view within a circle C in FIG.

In these figures, 1 is a seal member body,
A long strip-shaped upright portion 1a, a seal-cum-buffer portion 1b formed by making the upper portion of the upright portion 1a thinner than the upright portion 1a, and a horizontal direction from the side surface of the upright portion 1a. The rib 1c is provided so as to project, and the whole is integrally formed of an elastic body such as rubber and has a length of, for example, about 50 cm to 1 m.

The rib 1c has substantially the same thickness as the upright portion 1a,
The upright portion 1a is slightly thinner than the upright portion 1a, the tip side of which is bendable in the up-down direction, and on the outer surface of the upright portion 1a on the protruding side of the rib 1c, circular mounting recesses 1d are arranged at equal intervals in the longitudinal direction. Are formed. The mounting recess 1d is for fixing the seal member main body 1 to the side surface of the lid body 3 by a fixing means 4 such as a screw, and a thin recess 1e is formed by further providing a small recess at the center of the mounting recess 1d. When the seal member main body 1 is attached to the lid body 3, the thin portion 1e is easily pierced by the fixing means 4, and a part of the rib 1c matching the mounting recessed portion 1d is formed as shown in FIG. The notch 1f is formed,
The rib 1c does not interfere with the insertion of the fixing means 4.

On the other hand, the sewage groove 2 is, for example, a side groove laid on the road shoulder or a U-shaped groove laid across the road, and is made of concrete, and the lid 3 is provided in the opening 2a.
Can be fitted. The lid 3 is made of concrete or a grid made of metal called grating as shown in FIGS. 4 and 5, and angle side plates 3a are provided on both sides, and the lower surface of the horizontal part 3b of the side plate 3a is provided. It contacts the upper surface of the sewage channel 2. Further, a gap L is formed between the vertical portion 3c of the side plate 3a and the opening 2a, and the length of the lid 3 is substantially the same as the unit length of the sewer groove 2.

Next, the operation of the seal member constructed as described above will be explained. First, in covering the opening 2a of the sewer groove 2 provided so as to cross the road shoulder or the road with the lid 3, the seal member main body 1 is first described. As shown in FIG. 5, the upright portion of the seal / buffer portion 1b is bent so that the seal / buffer portion 1b is along the lower surface of the horizontal portion 3a of the side plate 3a provided on both sides of the lid body 3, as shown in FIG. 1a is brought into close contact with the outer surface of the vertical portion 3c, and in this state, the fixing means 4 is screwed from the mounting recess 1d to attach the seal member body 1 to the lid 3. Next, the opening 2 of the sewer 2
When the lid 3 is fitted to the a to cover the opening 2a, as shown in FIG. 4, the seal / buffer portion 1b is interposed between the upper surface of the sewer groove 2 and the horizontal portion 3b of the lid 3, and The tip of the rib 1c protruding from the upright portion 1a is brought into contact with the inner surface of the opening 2a of the sewer groove 2. At this time, even if there is variation in the gap L between the inner surface of the opening 2a of the sewer groove 2 and the lid 3, the tip side of the rib 1c bends in the vertical direction to follow the gap L, so the inner surface of the opening 2a The tip of the rib 1c can be reliably brought into contact with the.

As a result, since the sealing portion / buffer portion 1b prevents dirt and the like from entering between the upper surface of the sewage groove 2 and the lid body 3, the lid body 3 does not float up due to the earth and sand and the like. Even if a vehicle such as an automobile passes on the lid body 3 and the lid body 3 vibrates, noise is generated or cracks are generated in the sewer groove 2 and the lid body 3 because the vibration is absorbed by the seal / buffer section 1b. There is no problem such as occurrence of.

[0012]

As described above in detail, according to the present invention, when the opening of the sewer groove is covered with the lid, the seal / buffer portion of the seal member body is interposed between the upper surface of the opening of the sewer groove and the lid. Thus, the seal / buffer section can seal between the sewer groove and the lid. This prevents rainwater from entering the space between the upper surface of the sewer and the lid together with rainwater, so that the lid does not float up, so the lid does not obstruct traffic. In addition, even if a vehicle etc. passes over the lid and vibration occurs in the lid, the seal and cushioning part absorbs it, which causes noise and cracks in the drain and the lid, causing sewerage. Problems such as early damage to the groove and the lid can be eliminated.

Further, a rib protruding in the horizontal direction from the upright portion of the seal member main body abuts on the inner surface of the opening of the sewer groove,
Since the lid is prevented from shifting laterally, the lid does not slip into the sewer groove, and even if there is a variation in the gap between the sewer groove opening and the lid, the rib tip ends up and down. Since it bends in the direction and absorbs this variation, the tip of the rib can be reliably brought into contact with the inner surface of the opening of the sewer groove. Moreover, since the seal member main body is attached to the lid body in advance by the fixing means, the work of covering the sewer groove with the lid body is facilitated, so that the work efficiency is improved and the seal member body is displaced due to vibration after the construction. Since it does not fall off or fall off, there is no concern that the sealing effect and the cushioning effect will be reduced at an early stage.
