Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a revetment block.

[0002]

2. Description of the Related Art A revetment block is a substantially rectangular block made of concrete and is used for protection of a shore. Conventionally, this type of revetment block has various shapes.

[0003]

However, the conventional revetment blocks are emphasized in terms of their functionality and manufacturability, and it is an exaggeration to say that no consideration was given to the aesthetics of the shore. Was not.

Further, when stairs are provided on a conventional revetment wall, a block for stairs is separately used, but it is inconvenient if the revetment wall can only rise and descend from the stairs. It often happens that In order to avoid this, it is sufficient to increase the number of stairs, but this staircase is performed by using a separate stair block. The staircase block was made only for the convenience of people going up and down, and the aesthetic aspect was not considered at all. Therefore, in addition to the conventional revetment block which has not been produced in consideration of aesthetics, it is not preferable in terms of aesthetic appearance of the revetment wall to provide such stairs.

The present invention has been proposed in order to solve the aesthetic problems of the above-mentioned conventional revetment wall having stairs. The stairs are provided on the entire revetment wall, and the entire revetment wall is uniform. The purpose is to provide a shore protection block that can be made beautiful.

[0006]

In order to achieve the above-mentioned object, the present invention forms a spherical convex portion on a portion which becomes a quay wall surface of a revetment block, and forms a step portion on the spherical convex portion. The feature is that

[0007]

According to the present invention, since the surface of the revetment wall is provided with the spherical convex portion, it is possible to give an aesthetically-friendly impression, and the spherical convex portion is formed with a step portion as a pattern. Therefore, when constructing a revetment wall using this revetment block, a stair function is added to any part, and a person can easily climb up and down from any place.

[0008]

Embodiments of the present invention will now be described with reference to the accompanying drawings.

As shown in FIGS. 1 and 2, the revetment block 1 according to the first embodiment of the present invention has a base portion 10 having a square plate shape in plan view, and the center of the plane surface of the base portion 10 is provided. At the position, a spherical convex portion 11 having a diameter slightly smaller than the length dimension of the side of the base portion 10 is formed to project. Then, a part of the spherical convex portion 11 is cut and removed in the shape of an inclined plane, whereby a circular step portion 13 is formed. It should be noted that the ratio of the diameter dimension of the spherical convex portion 11 and the step portion 13 to the side dimension of the base portion 10 is not limited to the illustrated one, and the spherical convex portion 1
The diameter ratio of 1 to the step portion 13 is not limited to the illustrated one.

The step portion 13 is installed so that a person is going up and down the revetment wall so that it is horizontal when the revetment wall is in a completed state.
The angle θ formed by 3 and the base 10 is set in correspondence with the slope inclination angle of the seawall. That is, FIGS. 3A and 3B
As shown in FIGS. 4 (a) and 4 (b), the angles θ1 to θ4 formed by the step portion 13 and the base portion 10 can be set to various angles, and the inclination angle θ of the slope of the revetment wall can be set.
The larger X is, the larger the angle (θ1 to θ4) between the step portion 13 and the base portion is.

Grooves 15 for preventing slippage are formed in parallel in the step portion 13 at a predetermined interval. In order to prevent slippage, instead of such a groove 15, a convex strip may be provided, a mesh pattern may be provided, or an irregular specification such as rough gravel may be provided. It is a thing.

Next, a second embodiment of the present invention is shown in FIGS. Block 2 for revetment in the second embodiment
Has an elliptic spherical convex portion 21 formed at the center of a base portion 20 having a square plate shape in plan view. In the major axis direction of the elliptical spherical convex portion 21, a step portion 23 is formed which is an elliptical (oval) flat surface portion which is eccentric by being cut and removed into an inclined surface shape.

Although the step portion 23 is shown as a smooth surface in the figure, it is also in the second embodiment that the above-mentioned first portion is formed.
It goes without saying that the grooves, ridges, mesh pattern, rough gravel, etc. similar to those in the above embodiment may be formed. Further, the shape of the step portion 23, that is, the elliptic angle is not limited to that shown in the drawing.

Next, a third embodiment of the present invention is shown in FIG. Similarly, the revetment block 3 in the third embodiment also has a plate-shaped base portion 30 having a square plane. A spherical convex portion 31 is formed so as to project at the center of the base portion 30. Further, the spherical convex portion 31 is formed with a step portion 33 having a horizontally long rectangular shape close to a square. The step portion 33 is also configured as a flat surface portion as in the above embodiments. That is, the planar step portion of the first embodiment is circular, whereas the third embodiment is a rectangular step portion 33.

Next, a fourth embodiment of the present invention is shown in FIG. The revetment block 4 in the fourth embodiment also has a base portion 40 having a square plate shape in the same manner as in the above embodiments, and a spherical convex portion 41 is formed at the center of the base portion 40 so as to project. Has been done. Then, the spherical convex portion 41 is formed with a square square step portion 43. The step portion 43 is also formed as a flat surface portion as in the above-described embodiments. That is, the flat step portion of the first embodiment is circular, whereas the fourth embodiment is a square square step portion 43.

Next, FIG. 9 shows a fifth embodiment of the present invention. The revetment block 5 in the fifth embodiment also has a plate-shaped base portion 50 having a square plane, and a spherical convex portion 51 is formed at the center of the base portion 50 so as to project. The step portion 5 formed on the spherical convex portion 51 in the fifth embodiment.
3 is configured in an elliptical plane shape.

In the above third to fifth embodiments, the step portions 21, 31, 41 and 51 are smooth surfaces, but in these embodiments as well, the same as in the above first and second embodiments. It goes without saying that grooves, ridges, mesh patterns, rough gravel, etc. may be formed on the surface of the step portion.

Also in these embodiments, the angle formed by the step portion and the base portion is not particularly limited,
It may be set according to the slope angle of the revetment wall.

In the first to fifth embodiments described above, the revetment wall is configured such that the step portion is provided on the top end face side in view of the step function, but for the revetment of the present invention. If the block does not have a stair function and is merely intended for the aesthetic appearance of the revetment wall, the revetment block is oriented in the opposite direction to that shown in Fig. 3, that is, with the step portion facing downwards. You may comprise. Further, it goes without saying that the revetment wall may be configured so that the step portions are located laterally.

Further, in the present invention, it is not necessary to construct the revetment wall using only one type of revetment part block,
The revetment wall may be configured by combining the revetment blocks of each example.

[0018]

As described above, according to the present invention, since the step portion is formed in the spherical convex portion, when the revetment wall is constructed using the revetment block of the present invention, it can be located at any position. There is a staircase function, and it is not necessary to use a block for stairs separately on the revetment wall, and the appearance of the revetment wall can be improved.

Further, even if such a staircase function is provided,
When the revetment wall is viewed from the horizontal direction, the step portion is hidden by the spherical convex portion. Further, the presence of the spherical convex portion can give a gentle impression to the seawall.
