BACKGROUND ART Conventionally, drainage grooves such as gutters for draining rainwater have been provided on shoulders of roads, and
At the opening of the drainage gutter such as the gutter, a gutter lid is installed to prevent a person, a vehicle, or the like passing through the road from falling.

[0003] Generally, the groove lid installed at the opening of the drain groove, so-called drain groove groove lid, is made of steel, cast iron, or the like having a high strength so as to withstand the passage of heavy objects such as vehicles. The drain groove is made of a material and has a width approximately the same as the drain groove and a length of about 500 to 1000 mm, and a plurality of the drain groove and the drain groove are provided at the opening of the drain groove. Are arranged in series along the extension direction of.

By the way, since such a drainage groove lid has the above-described structure and arrangement, when an unbalanced load, an impact load, or the like is applied by the passage of a vehicle or the like,
The repulsive force may cause floating and rattling, and in extreme cases, jumping may occur, and there is even a risk of being detached from the opening of the drainage ditch.

For this reason, conventionally, in order to prevent such floating and rattling, such a groove lid is usually provided continuously to the opening of the drain groove in a state as shown in FIGS. 19 and 20. It was That is, the receiving frame 78 in which the bolts 76 are integrally erected upright at a predetermined plurality of locations (here, four locations) on the inner peripheral portion, and the through holes 80 at a predetermined plurality of locations (here, four locations) on the outer peripheral portion. Using the drain groove groove cover 82 provided with the above, the receiving frame 78 is installed at the opening of the drain groove 84, and each bolt 76 provided on the receiving frame 78 can be inserted into each through hole 80. Then, the groove lid 82 is placed on the receiving frame 78, and the nuts 86 are respectively fastened to the bolts 76 to fix the groove lid 82 to the receiving frame 78. It could be fixedly installed in the opening of the groove 84.

However, when the drain groove cover 82 is installed in the opening of the drain groove 84 as described above, the nuts 86 are fastened to the plurality of bolts 76 to install one groove cover 82. Since it is necessary to install a large number of groove lids 82, it is extremely troublesome and requires a lot of labor, such as fastening the nuts 86 individually to a large number of bolts 76. That is, the work efficiency in the installation work of the drain gutter groove cover 82 at the opening of the drain groove 84 is significantly reduced.

[0007]

The present invention has been made in view of the above circumstances, and a problem to be solved by the present invention is that lifting and rattling due to an impact when a vehicle passes can be effectively prevented. Another object of the present invention is to provide a drain groove groove lid connection structure in which a plurality of groove lids can be connected to the opening of the drain groove with good work efficiency.

[0008]

According to the present invention, in order to solve such a problem, an opening of a drainage groove provided on a road is continuously provided along an extension direction of the drainage groove, In the connection structure of a plurality of groove lids that cover the opening of the drainage groove,
In adjacent ones of the groove lids, a first engaging member made of an elastic material is provided on the surface of one groove lid facing the other groove lid, while the other one of the other groove lids is provided. A second engaging member made of an elastic material, which engages with the first engaging member, is provided on the surface facing to, and the first and second engaging members are engaged with each other, and they are adjacent to each other. Connection structure of drain groove groove lids configured such that the groove lids are connected to each other so that the adjacent groove lids are restrained from each other, and the floating or rattling of one groove lid can be suppressed by the other groove lid. Is its characteristic.

According to a preferred aspect of the drain groove groove lid connection structure according to the present invention as described above, the first engaging member is such that irregularities are alternately arranged in the height direction of the groove lid and the width thereof is wide. Direction has a corrugated or sawtooth-shaped first concavo-convex portion that continuously extends in the direction, while the concavo-convex groove is alternately formed so that the second engaging member can engage with the first concavo-convex portion. It has a wave-shaped or sawtooth-shaped second uneven portion arranged in the height direction of the lid and continuously extending in the width direction, and the adjacent groove lids are engaged by the engagement of the first and second uneven portions. Will be configured to be realized.

[0010]

In other words, in the drain groove groove lid connection structure according to the present invention, the first engaging member and the second engaging member are respectively provided on the facing surfaces of the groove lids adjacent to each other. By engaging and, the adjacent groove lids are restrained from each other, and the groove lids of one of the groove lids can be connected in a state where the rising or rattling of the groove lids can be suppressed by the other groove lid. Therefore, even if an unbalanced load or impact load is applied to the groove lid when the vehicle is passing under the condition that the groove lid is continuously connected to the opening of the drain groove, the groove lid may float up due to its repulsive force. The rattling can be effectively suppressed based on the mutual restraining force between the adjacent groove lids. Moreover, in such a drain groove groove lid connecting structure, the first engaging member and the second engaging member which are interposed between the adjacent groove lids and connect the groove lids in a mutually restrained state are provided. Since the engaging member and the engaging member are each made of an elastic material, the repulsive force against the impact when the vehicle passes can be effectively absorbed based on the elastic deformation action of the two engaging members. Therefore, the lift and rattling of the groove lid due to the repulsive force can be more effectively reduced.

Therefore, according to the drain groove groove lid connecting structure according to the present invention as described above, the first engaging member and the second engaging member are simply provided on the facing surfaces of the groove lids adjacent to each other. Just by engaging and connecting the groove lids,
It is possible to extremely effectively prevent the groove lid from being lifted or rattling due to an impact when the vehicle is passing, etc., and further, jumping or detaching from the opening of the drain groove can be very effectively prevented. At the time of installation, it is possible to eliminate the conventional work of tightening and fixing the nuts to the bolts provided on the receiving frame, and the labor required for that can be advantageously reduced, thus draining multiple groove lids. Therefore, the efficiency of the work performed when the grooves are connected to the opening of the groove can be dramatically improved as compared with the conventional case.

Further, in the present invention, the first engaging member has corrugations or sawtooth-shaped first irregularities in which irregularities are alternately arranged in the height direction of the groove lid and continuously extend in the width direction. On the other hand, the corrugations are alternately arranged in the height direction of the groove lid and extend continuously in the width direction so that the second engaging member can engage with the first concavity and convexity portion. When it is configured to have a second uneven portion having a shape or a sawtooth shape and the connection between the adjacent groove lids is realized by the engagement of the first and second uneven portions, The one engaging member and the second engaging member can be securely engaged with each other by a plurality of concaves and convexes having a large engaging area, and the elastic deformation of the concaves and convexes causes the engaging state of both the engaging members to change. It is easy to obtain and easy to dismantle, so that adjacent groove lids, and thus all Groove lid of the can relative to the opening of the drainage grooves, and than could be more easily and reliably provided continuously, even at the opening, the so that the can be easily removed.

By the way, in the rib 12 which constitutes such a groove lid 10, one side (left and right direction in FIG. 2) of the groove lid 10 corresponding to the continuous direction of the groove lid 10 is provided with a first side. One engaging member 16 and two second engaging members 18 on the other side are provided, each having a width substantially equal to the height of the rib 12 and a predetermined length.

As shown in FIGS. 5 and 6, the first engaging member 16 is made of a rubber plate material having a substantially rectangular shape, and one surface in the thickness direction has a short side direction. One side is a sawtooth-shaped first uneven portion 19, and the other end is a first lip portion 22. More specifically, the first concave-convex portion 19 has three convex stripes 20 having a triangular shape in the vertical cross section and two concave grooves 21 having a V-shape in the vertical cross section. The engaging members 16 are alternately arranged in the short side direction and are formed so as to extend continuously in the long side direction. The first lip portion 22 has a predetermined width, and is formed in a planar shape on the extension surface of the deepest portion of the concave groove 21 of the first concave-convex portion 19.

Further, in the first engaging member 16, a bolt hole 30 into which a mounting bolt 26 described later is inserted is provided at a substantially central portion thereof so as to penetrate therethrough in the thickness direction. And a nut groove 24 extending from the other end in the short side direction toward the bolt hole 30 at the central portion in the long side direction thereof. It is formed with a predetermined depth so as to engrave the uneven portion 19.

On the other hand, as apparent from FIGS. 7 and 8, the second engaging member 18 is also made of a rubber plate material having a rectangular shape, and the first engaging member 16 has the first engaging member 16. It has a second concave-convex portion 23 and a second lip portion 25 which have the same structure as the concave-convex portion 19 and the first lip portion 22. However, in the second engagement member 18, the formation positions of the second concave and convex portion 23 and the second lip portion 25 are reversed from those of the first engagement member 16. On one surface in the thickness direction, one end in the short side direction is a second lip portion 25, and the other end is a sawtooth-shaped second uneven portion 23. Further, also in the second engaging member 18, although the bolt hole 30 is provided at the substantially central portion thereof, unlike the first engaging member 16, the nut groove 27 is
The central portion in the long side direction is formed so as to extend from one end edge portion in the short side direction toward the bolt hole 30.

In short, one of the first engaging member 16 and the second engaging member 18 is rotated by 180 degrees around the bolt hole 30 about the bolt hole 30. , And is constructed so as to overlap the other one.

Thus, in the first engaging member 16 and the second engaging member 18, as shown in FIG. 9, the first uneven portion 19 and the second uneven portion 23 face each other. In this state, by being brought into contact with each other, two of the three ridges 20 of the first uneven portion 19 located on the side of the first lip portion 22 are two Of the three ridges 20 of the second concave-convex portion 23, two of which are located on the side of the second lip portion 25 while being pushed into the concave groove 21, are two of the first concave-convex portion 19. The first concave-convex portion 19 and the second concave-convex portion 23 are engaged with each other by being inserted into the concave groove 21,
As a result, the respective ridges 20 of both the uneven portions 19 and 23 are
Also, the relative movement of the concave grooves 21 in the arrangement direction and the relative movement of the concave grooves 21 in the twisting direction can be restricted at the same time.

Two first engaging members 16 and two second engaging members 18 having such a structure are used, and the ribs 12 are connected in the direction in which the groove lid 10 is connected. The first engaging members 1 are attached to both sides in one direction corresponding to each of the first engaging members 1 as shown in FIGS. 1 and 2.
6, the rib 12 is brought into contact with both end portions of the end surface 32 on one side in one direction on the surface opposite to the first concavo-convex portion 19, and the first concavo-convex portion is formed. 19

Are inserted into the bolt holes 30 of the first engaging members 16, and the nuts 2 are attached to the mounting bolts 26.
8 are fastened together so that they can be attached. In addition, each second engagement member 18
Then, at both end portions of the end surface 34 on the other side in one direction of the rib 12, at positions corresponding to the respective first engaging members 16 provided on the end surface 32 on the one side, similar to those. Then, they are brought into contact with each other and attached. In this case, the tip end of the leg portion of the mounting bolt 26 and the nut 28 are housed in the bolt grooves 24, 27 of the first and second engaging members 16, 18, respectively. And thereby each concave groove 2 of the first and second concave and convex portions 19 and 23.

The engagement state of 9, 23 can be ensured satisfactorily.

Thus, the two first engaging members 16 are attached to the end surface 32 on one side of the rib 12 in one direction, that is, the end surface 32 on the one side in the direction in which the groove lid 10 is connected to the side groove 15. On the other hand, two of the second engaging members 18 are the end faces 34 of the rib 12 on the other side in one direction, that is, the groove lid 1.
It is attached to the end surface 34 on the other side in the continuous installation direction of 0, whereby the first engagement is made on the facing surfaces of the adjacent groove lids 10 in the continuous installation state with the side groove 15. The member 16 and the second engagement member 18 are provided.

Therefore, the groove lid 10 having such a structure.
When a plurality of the above are placed on the receiving frame 17 and continuously provided in the opening of the side groove 15, first, as shown in FIG. , The end face 32 provided with the first engagement member 16 and the second fitting member 18
Is arranged so as to face the end surface 34 provided with
Then, as shown in FIG. 10B, the first concave-convex portion 19 of the first engaging member 16 and the second concave-convex portion 23 of the second engaging member 18 are engaged and connected. If
The adjacent groove lids 10 and 10 form the first uneven portion 19
And relative movement in the arrangement direction of each ridge 20 and each groove 21 of the second uneven portion 23 and their relative movement in the twisting direction, in other words, in the height direction of the groove lid 10. The movement and the rotation about the connecting direction are mutually restrained so that they can be regulated at the same time.
And thereby, those adjacent groove lids 10, 10
Lifting and rattling of one of the groove lids 10 can be effectively suppressed by the other groove lid 10.

Therefore, in such a groove lid 10, even if an unbalanced load or an impact load is applied by the passage of a vehicle or the like under the condition that the groove cover 10 is continuously connected to the opening of the side groove 15, the repulsive force of the groove cover 10 It is possible to effectively prevent the floating and rattling, and it is also possible to effectively prevent the jumping and the separation of the side groove 15 from the opening.

Moreover, in the groove lid 10, when the groove lid 10 is continuously provided in the opening of the side groove 15, it is simply placed on the receiving frame 17 provided in the opening, and the receiving frame 17 as in the conventional case is provided. Since there is no fixing of bolts and nuts to the

Further, in the groove cover 10, since the first engaging member 16 and the second engaging member 18 are made of a rubber material, they are repelled against a shock or the like when the vehicle passes. The force can be effectively reduced by the elastic deformation action of both of the engaging members 16 and 18, and the effect of preventing lifting and rattling based on the repulsive force can be enhanced more effectively.

Further, in the groove cover 10 according to this embodiment, the first engaging member 16 and the second engaging member 18 are formed so as to extend continuously in the long side direction thereof. The strips 20 are made to project into a plurality of recessed grooves 21 which are also formed so as to continuously extend in the long side direction thereof, and have a large engaging area and are engaged at a plurality of locations. Therefore, the engaged state of both the engaging members 16 and 18 can be obtained with high reliability.

Furthermore, in the groove cover 10, the first engaging member 16 and the second engaging member 18 are the first concave and convex portion 19 and the second concave and convex portion 23 of the serrated line. The first engaging member 16 is elastically deformed by the elastic deformation of the first and second concave and convex portions 19 and 23.
The engagement state between the second engagement member 18 and the second engagement member 18 can be easily obtained, and the second engagement member 18 can be easily eliminated, and the connection and removal of the adjacent groove lids 10 and 10 can be easily performed. As a result, the work of connecting or removing a large number of groove lids 10 to the opening of the side groove 15 can be performed more easily and efficiently.

Further, in the groove cover 10, since the first engaging member 16 and the second engaging member 18 are made of a rubber material, both the engaging members 16 and 18 are formed. Even if there is a dimensional error between the respective ridges 20 and the respective concave grooves 21 provided in the above, the dimensional error can be advantageously absorbed by the elastic deformation of the respective ridges 20 or the respective concave grooves 21.

Further, in the groove cover 10, the first engaging member 16 and the second engaging member 18 are shaped so as to have a point-symmetrical relationship about the bolt hole 30. Therefore, it is possible to use both the first engaging member 16 and the second engaging member 18 with one type of shape. Therefore, in this embodiment, both of these engaging members are engaged. The advantage is that the members 16 and 18 can be easily manufactured.
