TECHNICAL FIELD OF THE INVENTION
The present invention relates to a gutter body and a gutter cover, and more particularly to a joining structure between a gutter body and a gutter cover and a joining structure between gutter covers in a case where the gutter cover is attached to an upper surface opening of the gutter body. It is.
[0002]
[Prior art]
Gutters are provided on the side of the road and on the site as drainage channels for rainwater and the like. As the side groove, for example, a side groove main body having a substantially U-shaped cross section with an open upper surface and a plurality of side groove lids closing the upper surface of the side groove main body are known. The gutter main body is composed of a pair of left and right side walls and a bottom wall forming a water channel together with these side walls, and has a gutter-like appearance as a whole. In addition, a lid contact surface that contacts the bottom surface of the gutter cover and mounts the gutter cover is formed on an upper portion of each side wall.
[0003]
In addition, the lid contact surface is curved with a substantially constant radius of curvature, and both end portions in the width direction of the bottom surface of the side groove cover (side groove contact surface) are formed into curved surfaces corresponding to the shape of the lid contact surface. Is also known. According to this, both the gutter contact surface and the lid abutment surface are formed into similar curved surfaces, so that both abutment surfaces are in close contact with each other, particularly when a load is applied from above the gutter lid. , The load is dispersed at the point of contact between the two contact surfaces. For this reason, the adhesion between the two contact surfaces is further increased, and even if a load of an automobile or the like is applied to the gutter cover, rattling of the gutter cover is suppressed.
[0004]
Generally, two or more gutter lids are attached to one gutter body with their end faces abutting each other. In particular, in the case where the upper surface opening of the gutter main body is opened over the entire surface, when the gutter main bodies are arranged adjacent to each other, a plurality of gutter lids are attached in a row.
[0005]
At the time of filing the present application, the applicant has found the following documents describing the above-mentioned prior art.

[Problems to be solved by the invention]
However, in the above-mentioned gutter, although the lid abutment surface and the gutter abutment surface formed at the left and right ends of the gutter lid are formed into similar curved surfaces, it is possible to prevent rattling in the left-right direction. The end in the length direction of the gutter cover (that is, the traveling direction of the vehicle) fluctuates in the vertical direction due to passage or the like, and as a result, noise may be generated or the corner may be damaged. In other words, when the load of the vehicle is applied only to one end in the length direction of the gutter cover, the other end is lifted with the fulcrum around the center of the gutter cover, and then the other end fluctuates downward as the load moves to the vicinity of the center. It collides with the lid contact surface. Further, when the load further moves forward, the load is applied to the other end side, so that the one end side is lifted. Thereafter, when the vehicle passes, the one end side fluctuates downward due to its own weight and collides with the lid contact surface. As described above, each time the tire of the vehicle passes over the gutter lid, the gutter lid swings like a so-called seesaw and collides with the lid contact surface, thereby causing noise and breakage.
[0007]
In the first place, since the gutter lid needs to be detached when cleaning or inspecting the inside of the gutter, it is mounted so that a slight gap is formed between the gutter lid and the upper surface opening, that is, around the gutter lid. Was. For this reason, when the position to which the load is applied changes with the passage of time due to the passage of the vehicle or the like, the end portion is lifted up or swings like a seesaw.
[0008]
In addition, if there is a gap around the gutter, not only the fluctuation in the vertical direction, but also if the gutter cover is pushed in the length direction by the rotation of the tire, the gutter cover moves in the length direction, In some cases, sound was generated due to collision between the lid and the gutter main body or between the gutter lids. In particular, since the end face in the length direction of the gutter cover and the face opposing it are formed as vertical planes, the planes collide with each other, causing a loud noise.
[0009]
Further, in a gutter in which a plurality of gutter covers are laid in a row, the plurality of gutter covers may be sequentially displaced, and in this case, the gaps provided between the gutter covers may accumulate, resulting in a large gap. Was. In particular, when such gutters are provided along a slope, a plurality of gutter covers are biased downward, so that a large gap is easily formed. If a large gap is formed on the side of the road, it is difficult to ensure the safety of pedestrians and vehicles.
[0010]
In view of the above circumstances, an object of the present invention is to provide a gutter body and a gutter cover capable of suppressing generation and damage of noise due to collision between the gutter cover and the gutter body, or between the gutter covers. is there.
[0011]
[Means for Solving the Problems]
The gutter cover according to the first aspect of the present invention is a gutter cover attached to an upper surface opening of the gutter main body, and having a longitudinal end face opposed to the inner standing surface of the gutter main body, wherein the inner standing surface has A projection is formed integrally with the opposed end face, and protrudes from a lower portion of the end face toward the inner standing surface.
[0012]
Here, the “longitudinal direction” means a vertical direction with respect to the upper surface of the gutter cover. The “projection” may be formed over the entire width of the end face, or may be formed only on a part of the end face. When attaching the gutter to the opening on the upper surface, it is desirable to make the tip of the protruding portion abut on the inner erected surface, but it is not always necessary to make it abut, and noise is generated due to fluctuation and displacement in the vertical direction. A small gap may be formed as long as it is not within the range. Hereinafter, the expression “substantially abutting” is used to include such a state.
[0013]
Therefore, according to the gutter cover of the first aspect of the present invention, when the gutter cover is mounted on the upper surface opening of the gutter body, the end face of the gutter cover faces the inner standing surface of the gutter body and the tip of the protrusion formed on the end face. Is substantially in contact with the inner standing surface.
[0014]
For this reason, in a state where the gutter cover is attached to the upper surface opening, that is, in a normal use state, even when the vehicle passes over the upper surface of the gutter cover, the protrusion that is a part of the gutter cover is provided on the inner standing surface. Due to the substantial contact, lifting of the gutter cover due to a change in load is suppressed, and displacement of the gutter cover in the length direction due to rotational force of a tire or the like is suppressed. As a result, the generation of noise due to the collision is prevented, and the corner of the gutter is prevented from being damaged.
[0020]
A gutter cover according to a second aspect of the present invention is a plurality of gutter lids attached to the upper surface opening of the gutter main body with their longitudinal end faces abutting each other, and is formed integrally with at least one of the end faces. And a protruding portion protruding from a lower portion of the end face toward the other end face to be abutted.
[0021]
Therefore, according to the gutter cover of the fourth aspect, when a plurality of gutter covers are attached to the upper surface opening of the gutter main body, the end faces of the adjacent gutter lids face each other, and the protruding portions formed on the end faces are formed. The tip is substantially in contact with the end face of the other adjacent gutter cover. In other words, the same effect as in the case where the inner standing surface in the invention of claim 1 is replaced with the end surface of the other side groove cover is exerted. For this reason, in a state where the plurality of gutter lids are attached to the upper surface opening, lifting of the gutter lid and displacement of the gutter lid in the length direction are suppressed. Further, since no displacement occurs, it is possible to arrange a plurality of gutters at equal intervals.
[0022]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, a gutter 1 according to a first embodiment of the present invention will be described with reference to FIGS. FIG. 1 is an exploded perspective view showing a configuration of the side groove 1, and FIG. 2 is an explanatory diagram showing a configuration of a main part in the side groove 1. The side groove 1 of the present embodiment includes a side groove main body 2 and a side groove cover 3. The gutter main body 2 is a secondary concrete product, and includes a pair of side walls 4 opposed to each other and an upper wall 5 for closing an upper surface of a water channel formed by these side walls 4, and has an inverted U-shaped cross section. ing. A rectangular upper surface opening 6 is provided in the center of the upper wall 5 so as to penetrate the upper wall 5, and an upper part of each side wall 4, that is, a lower part of the left and right ends of the upper surface opening 6 is opposed to each other. A curved lid contact surface 7 that is curved with a substantially constant radius of curvature is formed so that the interval between the side walls 4 becomes smaller toward the lower side. The inner standing surface 8 in the length direction L of the upper opening 6 is a vertical plane.
[0023]
On the other hand, the gutter lid 3 is a secondary concrete product like the gutter body 2 and has a flat rectangular parallelepiped appearance. The gutter cover 3 is attached to the upper surface opening 6 of the gutter body 2, and the upper surface opening 6 is closed by, for example, two gutter covers 3. Specifically, at the left and right lower end portions of each gutter lid 3, a gutter contact surface 14 having a shape similar to the shape of the lid abutment part 7 is formed, and when the gutter lid 3 is inserted into the upper surface opening 6. The lid contact portion 7 and the gutter contact surface 14 are in contact with each other, and the gutter cover 3 is supported while being placed on the lid contact portion 7. When the gutter cover 3 is mounted, the height of the upper surface 10 of the gutter cover 3 matches the height of the upper wall 5 and becomes substantially the same. The end face 11 in the length direction of the side groove cover 3 has a holding recess 13 depressed in the length direction L side, and a protrusion protruding toward the opposed inner standing surface 8 side or the other side groove cover 3 side. A part 12 is formed. The holding recess 13 is provided at the center of the end face 11, and the protrusion 12 is provided only at the lower end corner of the end face 11. When a plurality of (for example, two) side groove lids 3 are attached to the upper surface opening 6, the protrusion length of the protrusion 12 is such that the tip of the protrusion 12 contacts the inner standing surface 8 and the other side groove cover 3. The length is set to be in contact with or very close to. Here, the gutter cover 3 corresponds to the gutter cover according to the first aspect of the present invention.
[0024]
As described above, in this example, the protrusion 12 is provided at the lower end corner of the gutter cover 3, and the entire length is adjusted so that the tip of the protrusion 12 abuts on the inner standing surface 8 and the other gutter cover 3. With the setting, the gutter cover 3 is prevented from being inclined when the gutter cover 3 is attached to the upper surface opening 6. For example, when the vehicle passes through the upper surface 10 of the gutter cover 3, the gutter cover 3 is closed. Even when a load is applied to one end of the side groove 3, the other end of the side groove cover 3 is prevented from lifting. Further, since the gap around the side groove cover 3 is reduced, there is no displacement in the length direction L. For this reason, the generation of noise due to the collision can be prevented, and the corner of the side groove cover 3 can be prevented from being damaged.
[0025]
Further, since a relatively wide gap is formed around the upper side of the gutter cover 3, when removing or attaching the gutter cover 3, it becomes possible to insert a hand or a tool into the gap. .
[0026]
Next, a side groove 21 according to a second embodiment of the present invention will be described with reference to FIG. FIG. 3 is a cross-sectional view showing the configuration of the side groove 21. The side groove main body 22 of this side groove 21 is substantially the same as the configuration of the side groove main body 2 of the first embodiment, and only the shape of the inner standing surface 26 is different. That is, a protruding portion 28 protruding toward the end surface 27 of the gutter cover 23 is formed at the lower end corner of the inner standing surface 26, and the protruding portion 28 is so arranged that the tip of the protruding portion 28 substantially abuts the facing end surface 27. Is set. In other words, when two gutters 23 are attached, the length L3 of the upper surface opening 24 except for the portion above the protrusion 28 is substantially equal to twice the length L4 of the gutter 23. The protrusion length of the protrusion 28 is set. Here, the side groove main body 22 corresponds to the side groove main body according to the second aspect of the present invention.
[0027]
On the other hand, no projecting portion is formed on the end surface 27 of the side groove cover 23, and the end surface 27 is a vertical plane except for the portion where the holding concave portion 13 is formed. That is, the present embodiment is characterized in that the protrusion 28 is provided on the inner standing surface 26 side as compared with the side groove 1 of the first embodiment.
[0028]
As described above, the projection 28 is provided at the lower end corner of the inner standing surface 26 and the entire length is set so that the tip of the projection 28 abuts on the end surface 27. Even if the vehicle passes, lifting of the gutter 23 and displacement in the length direction L are prevented. That is, the generation of noise due to the collision can be prevented, and the corner of the gutter 23 can be prevented from being damaged.
[0029]
Also, when removing one gutter cover 23 from the upper surface opening 24 of the gutter main body 22, it is necessary to lift the gutter cover 23 straight up to a height at which the bottom surface of the gutter cover 23 is higher than the upper surface of the projection 28. However, if the height exceeds the height, a relatively wide gap is formed around the gutter cover 23, so that the gutter cover 23 can be lifted even in a slightly inclined state. On the other hand, when the gutter cover 23 is attached to the upper surface opening 24 of the gutter body 22, the gutter cover 23 can be inserted even in an inclined state until the bottom surface of the gutter cover 23 is lower than the upper surface of the protrusion 28. In short, regarding the attachment and detachment of the gutter cover 23, the protrusion 28 is formed only at the lower end corner of the inner erected surface 26, thereby restricting the thickness in the thickness direction, similarly to the case where the depth of the upper surface opening 24 is reduced. Is alleviated.
[0030]
In particular, in the side groove 21 of the present example, the tip corner 28a is cut out in a round shape or a linear shape so that the upper surface of the protruding portion 28 becomes a downward slope. For this reason, when attaching the gutter cover 23 to the upper surface opening 24, even if the lower end corner of the gutter cover 23 is placed on the protruding portion 28, the gutter cover 23 is guided by the tip corner 28a and is smoothly inserted. You. That is, workability is improved, and the burden on the operator can be further reduced.
[0031]
Next, a side groove 51 according to a third embodiment of the present invention will be described with reference to FIGS. FIG. 4 is a perspective view showing a configuration of the side groove 51, and FIG. 5 is an explanatory diagram showing an arrangement state of the side groove cover 53 in the side groove 51. As shown in FIG. 4, the side groove 51 of the present example includes a side groove main body 52 and a side groove cover 53. The gutter main body 52 is a concrete secondary product, and includes a pair of side walls 54 facing each other, and a bottom wall 55 that forms a water channel together with these side walls 54, and has an overall gutter-like appearance. On the upper part of each side wall 54, a curved lid contact surface 56 curved with a substantially constant radius of curvature is formed so that the distance between the opposing side walls 54 becomes smaller toward the lower side. Note that two or more gutter lids 53 are attached to one gutter main body 52. In particular, since the upper surface of the gutter main body 52 is open throughout the lengthwise direction L, a plurality of gutter lids 53 are laid in a line by arranging the gutter main bodies 52 adjacent to each other. It becomes possible.
[0032]
On the other hand, the gutter lid 53 is a secondary concrete product like the gutter main body 52, and has a flat rectangular parallelepiped appearance. The gutter cover 53 is placed on the lid contact surface 56 of the gutter body 2 and closes the upper surface of the gutter body 52. Note that, similarly to the first embodiment, the lower left and right portions of the side groove lid 53 have a shape similar to the shape of the lid contact surface 56 (excluding congruence). A projecting portion 60 projecting in the horizontal direction is formed on one end face 59 of the side groove cover 53. The protrusion 60 is provided only at the lower end corner of one end face 59. The other end surface 61 is a vertical plane except for the holding concave portion 62. Here, the gutter cover 53 corresponds to the gutter cover according to the fourth aspect of the present invention.
[0033]
As described above, in this example, by providing the protruding portion 60 on one end face 59 of the gutter cover 53, when laying the plurality of gutter covers 53, the end face 59 of the predetermined gutter cover 53 (specifically, the Even if the front end) abuts against the end face 61 of the other side groove lid 53, it can be easily attached and detached by the same operation as the second embodiment. Then, by making the end of the protruding portion 60 and the end face 61 that are opposed to each other substantially contact each other, lifting of the end portion of each side groove cover 53 and displacement of the side groove cover 53 in the longitudinal direction L are eliminated, and the collision may occur. Generation of noise can be prevented. Further, since the formation of a large gap due to the cumulative displacement is prevented, the safety of pedestrians and drivers can be improved. In particular, if the gutter cover 53 of the present embodiment is applied as a gutter cover laid along a slope, a great effect can be obtained.
[0034]
As described above, the present invention has been described with reference to three preferred embodiments. However, the present invention is not limited to these embodiments, and as described below, various modifications may be made without departing from the spirit of the present invention. And design changes are possible.
[0035]
That is, in the above three embodiments, the present invention is applied to a concrete gutter, but the present invention is applied to a metal gutter (grating) or a cast gutter (tag tile). May be applied.
[0036]
In the above-described first and second embodiments, the protrusion is provided at the lower part of the gutter, but may be provided at the upper part. However, if provided in the lower part, a gap is formed between the tip of the protrusion and the end face of the gutter cover or the inner standing surface of the gutter body, and the end side of the gutter cover is lifted. Also, the protrusion does not protrude upward from the upper surface of the side groove main body. For this reason, it is possible to prevent the side groove cover from being returned to the original state due to the protrusion and being prevented from being damaged. Further, when the protrusion is provided at the lower part, a gap is formed at the upper part, so that the workability at the time of attachment and detachment can be improved.
[0037]
Further, in the above three embodiments, the protrusion is formed integrally with the gutter body or the gutter cover, but the protrusion formed by a separate member is attached to the gutter body or the gutter cover. Is also good. However, if the protruding portion is formed by integral molding as described above, the assembling work or the like becomes unnecessary, and the work can be prevented from becoming complicated.
[0038]
Furthermore, in the above-mentioned three embodiments, the lid contact surface and the side groove contact surface are formed with curved surfaces to prevent rattling. It may be prevented. Further, the present invention may be applied to a conventional side groove having no backlash prevention means, that is, a normal side groove in which both a lid contact surface and a side groove contact surface are formed at right angles.
[0039]
【The invention's effect】
As described above, according to any one of the first to fourth aspects of the present invention, by forming the protruding portion on the end face or the inner erected surface, it is possible to change the up-down direction and the lengthwise displacement of the side groove cover. Is suppressed, and collision between the gutter lid and the gutter body or between the gutter lids can be prevented. For this reason, generation of noise is prevented, and corners of the gutter cover are prevented from being damaged, so that the durability of the gutter and the comfort of residents can be improved. Further, according to the third aspect of the present invention, it is possible to relatively easily attach and detach the side groove cover, and it is possible to reduce the burden on the operator and the like.
