Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a gutter structure which is embedded in a side portion of a general road and used as a drainage channel.

[0002]

[Prior art]

 In the conventional gutter structure, for example, the gutter body and the gutter lid are opposed to each other at the inclined surface portions, and these are engaged via packing so as to avoid noise generation when the vehicle travels on the gutter lid. The above is proposed (Japanese Utility Model Publication No. 62-14280).

Further, as another conventional gutter structure, as shown in FIG. 4, a gutter skeleton body 21 and a gutter groove cover 22 are brought into close contact with each other by curved surfaces 21a, 22a which are geometrically similar to each other, so that when the vehicle is traveling, It has been proposed to avoid noise generation and damage to the gutter body 21 and the gutter lid 22.

[0004]

[Problems to be solved by the device]

 However, in the case of a gutter structure in which the packing is interposed between the gutter body and the gutter lid, it is necessary to embed the packing in the concrete, which is difficult to handle at the time of molding processing and construction laying. However, there was a problem that it was large and annoying.

Further, in the case where the gutter body 21 and the gutter lid 22 are closely adhered by the similar curved surfaces 21a and 22a, it is necessary to use a highly accurate steel mold, which increases the cost of the mold and the molding. There was a problem that it was necessary to manage the dimensions sufficiently, and there were difficulties in terms of economic efficiency and workability.

Further, in the case where the curved surfaces 21a and 22a are closely attached, the gutter cover 22 is likely to be fitted obliquely to the gutter body 21, and the gutter cover 22 projects upward by K at one end in the width direction. At the other end, there is a problem that the upper surface of the adjacent gutter lid 22 does not have a uniform horizontal surface and becomes uneven, as it sinks downward by K minutes.

The present invention solves the above-mentioned problems, and can secure sufficient strength for running of a vehicle, prevent rattling of the gutter lid, and prevent the gutter after passing the vehicle. An object of the present invention is to provide a gutter structure excellent in economy and workability, which can prevent the gutter lid from protruding or sinking in the width direction while preventing the lid from jumping up.

[0008]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, a gutter structure according to the invention of claim 1 has an upper inclined surface portion formed on an inner surface of a side groove wall facing a gutter frame body, and a substantially horizontal extending continuously downward from the upper inclined surface portion. A wall-side horizontal plane portion, a wall-side curved surface portion that extends downward from the wall-side horizontal surface portion, and a wall-side small inclined surface portion that extends downward from the wall-side curved surface portion. And a gutter lid, which is substantially vertical to the upper inclined surface portion and is opposed to the upper inclined surface portion with a gap, and which extends downwardly continuously from the upper lid vertical surface portion. A substantially horizontal lid-side horizontal plane section facing the side-horizontal plane section through a gap, a lid-side curved plane section that extends downwardly continuously from the lid-side horizontal plane section and makes line contact with the wall-side curved plane section, and It is extended continuously downward to the curved surface on the lid side and faces the small inclined surface on the wall side with a gap. Those constructed from the wall side small inclined surface portion.

Further, in the gutter structure according to the invention of claim 2, the gap between the wall-side horizontal surface portion and the lid-side horizontal surface portion is defined by the wall-side lower horizontal surface portion and the gutter lid bottom surface which are continuous with the wall-side small inclined surface portion. It is designed to be larger than the gap.

[0010]

[Embodiment of the invention]

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a vertical sectional view showing a side groove structure of the present invention, and FIG. 2 is an enlarged sectional view of a main part thereof.

In FIG. 1, the gutter skeleton body 1 is provided with upper sloped surface portions 2a and 2b formed on the inner surfaces of the side groove walls 2A and 2B facing each other, and extending downward from the upper sloped surface portions 2a and 2b. Substantially horizontal wall-side horizontal planes 3a and 3b, wall-side curved planes 4a and 4b extending downward from the wall-side horizontal planes 3a and 3b, and wall-side curved planes 4a and 4b. Has wall-side small inclined surface portions 5a and 5b continuously extended downward, and wall-side lower horizontal surface portions 6a and 6b extended below the wall-side small inclined surface portions 5a and 5b.

On the other hand, the gutter lid 7 is connected to the lid-side upper vertical surface portions 8a and 8b and the lid-side upper vertical surface portions 8a and 8b which are substantially vertical to face the upper inclined surface portions 2a and 2b with a gap therebetween. Substantially horizontal lid-side horizontal plane portions 9a and 9b that are extended downward and face the wall-side horizontal plane portions 3a and 3b with a gap, and the lid-side horizontal plane portions 9a and 9b are continuous. Lid-side bent curved surface portions 10a and 10b extending downward and in line contact with the wall-side bent curved surface portions 4a and 4b, and extending downward continuously from the lid-side bent curved surface portions 10a and 10b, It has the lid side small inclined surface portions 11a and 11b facing the wall side small inclined surface portion with a gap, and the gutter lid bottom surface 12 extending downward continuously from the lid side small inclined surface portions 11a and 11b. .

Here, the outer diameter of the gutter lid 7 is formed smaller than the minimum inner diameter portion of the upper inclined surface portions 2a and 2b of the gutter body 1, and a gap G1 is provided that slightly expands toward the upper portion. The length of the wall-side horizontal planes 3a and 3b is longer than that of the lid-side horizontal planes 9a and 9b, and a small gap H is formed between the wall-side horizontal planes 3a and 3b and the lid-side horizontal planes 9a and 9b. Are formed.

Further, a minute gap G2 is provided between the wall-side small inclined surfaces 5a, 5b and the lid-side small inclined surfaces 11a, 11b, and further, the bottom surface of the gutter lid near the lid-side small inclined surfaces 11a, 11b. A gap h is provided between the wall 12 and the lower horizontal surfaces 6a and 6b on the wall side.

In the gutter structure having such a configuration, when the gutter lid 7 is fitted into the gutter body 1, as shown in FIG. 3, first, the wall-side horizontal plane portions 3 a and 3 b of the gutter body 1 are first attached. On the other hand, the gutter lid 7 is erected horizontally and supported so that both ends of the lid-side upper vertical surface portions 8a and 8b are placed.

Subsequently, the gutter lid 7 is slowly laid down in the direction of the arrow A, and as shown in FIG. 1, the lid-side horizontal plane portions 9a and 9b are separated from the wall-side horizontal curved surface portions 3a and 3b. The lid-side curved surface portions 10a and 10b are laid so as to face 4a and 4b, and the periphery of the gutter lid bottom surface 12 of the gutter lid 7 faces the wall-side lower horizontal surface portions 6a and 6b, respectively.

Therefore, when the gutter lid 7 is attached to the gutter skeleton body 1, the lid side curved surface curved portions 10a and 10b are always in line contact with the wall side curved curved surface portions 4a and 4b, and the side groove curved portions 4a and 4b are in contact with each other. A load such as a vehicle weight applied on the lid 7 is received by all of the wall-side curved surface portions 4a, 4b and stably supported.

At this time, the wall-side horizontal plane portions 3a, 3b and the lid-side horizontal plane portions 9a, 9b face each other with a gap H 2, and the gutter lid bottom surface 12 of the gutter lid 7 and the wall-side lower horizontal plane portions 6a, 6b. Since they are opposed to each other via a gap h, the above-mentioned load is not applied to the gutter lids 2A and 2B from here.

Then, the gaps H and h are limited to very small dimensions, and the lid-side curved surface portions 10a and 10b may be displaced vertically with respect to the wall-side curved surface portions 4a and 4b. However, the deviation is projected to only one side by joining the lid-side horizontal plane portions 9a, 9b to the wall-side horizontal plane portions 3a, 3b or by joining the periphery of the gutter lid bottom surface 12 and the lid-side lower horizontal plane portions 6a, 6b. Alternatively, a large dent does not occur, and the upper surface of the gutter lid 7 can be maintained substantially horizontal as a whole.

In addition, by setting the relationship of the gap H> the gap h, it is possible that the peripheral portion of the bottom portion of the gutter lid 7 and the wall-side lower horizontal surface portions 6a and 6b collide with each other due to the above-mentioned displacement, so that they are slightly crushed. Even if there is, the lid-side horizontal plane portions 9a and 9b do not join to the wall-side horizontal plane portions 3a and 3b, and it is possible to avoid the occurrence of a large crack in the main body portion of the gutter lid 7.

Further, by setting the gap G2 between the wall-side small inclined surface portions 5a and 5b and the lid-side small inclined surface portions 11a and 11b and the length of the gap G2 to an arbitrary minute dimension, the wheels of the vehicle are provided with the gutters. Even when the gutter lid 7 tries to bounce up by riding on the lid 7 and concentrating the load on a part thereof, the lid-side small inclined surface portions 11a and 11b are separated from the side wall small inclined surface portions 5a and 5b. Since they collide with each other, it is possible to prevent the gutter lid 7 from further jumping up, thereby avoiding the occurrence of a major accident.

Further, since there is a gap G1 between the substantially vertical lid-side upper vertical surface portions 8a and 8b of the gutter lid 7 and the upper inclined surface portions 2a and 2b of the gutter frame body 1, opening / closing operation of the gutter lid 7 is performed. It has the advantage of being easy. This gap G1 can be adjusted by forming the lid-side upper vertical surface portions 8a, 8b of the gutter lid 7 substantially parallel to the upper inclined surface portions 2a, 2b of the gutter frame body 1. When the gap G1 is narrowed, the gap G1 can be adjusted. It is possible to reduce the invasion of earth and sand into the ground.

By providing a reinforcing member or a holding member made of plastic or steel in the contact portion of the gutter frame body 1 with each portion of the gutter lid 7, wear and loss of the contact portion at the time of closing the lid can be prevented. It can be effectively prevented.

[Effect of the invention]

 As described above, according to the first aspect of the present invention, the gutter frame body is provided with the upper inclined surface portion formed on the inner surface of the facing gutter lid, and the substantially horizontal wall side extending continuously downward from the upper inclined surface portion. Consists of a horizontal surface portion, a wall-side curved surface portion that extends downward continuously from the wall-side horizontal surface portion, and a wall-side small inclined surface portion that extends downwardly continuously from the wall-side curved surface portion. The gutter lid is a substantially vertical lid-side upper surface facing the upper inclined surface portion with a gap, and the gutter lid is continuously extended downward from the lid-side upper vertical surface portion to extend to the wall-side horizontal surface. A substantially horizontal lid-side horizontal surface portion facing the surface portion through a gap, a lid-side curved surface portion that extends downwardly continuously from the lid-side horizontal surface portion and is in line contact with the wall-side curved surface portion, and the lid. A small sloped surface on the lid side that extends downward from the curved surface of the side wall and faces the small sloped surface on the wall side with a gap. Since it is made up of two parts, it is possible to secure sufficient strength for running the vehicle, prevent rattling of the gutter lid, and prevent the gutter lid from jumping up after passing the vehicle, while keeping the gutter lid in the width direction. The effect is that it can be prevented from protruding or sinking.

According to the second aspect of the present invention, the gap between the wall-side horizontal surface portion and the lid-side horizontal surface portion is formed between the wall-side lower horizontal surface portion and the gutter lid bottom surface that are continuous with the lid-side small inclined surface portion. Since it is configured to be larger than the gap, even if the lower horizontal part on the wall side or the bottom part of the gutter lid is partly crushed, the occurrence of cracking due to shear fracture in the main part of the gutter lid 7 is avoided. Therefore, it is possible to effectively prevent the occurrence of cracks in the entire gutter lid.
