Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a revetment block that is stacked to cover a shore such as the sea or a river.

[0002]

[Prior art]

 There is a concrete revetment block that has a square front part with a side of about several tens of cm when viewed from the front and an anchor part at the rear.

[0003] This type of revetment block is stacked on a shore such as a pond or river like a stone wall, and the front portion of the revetment block generally has only a slight unevenness for forming a pattern. It is made substantially planar.

[0004]

[Problems to be solved by the invention]

 If a large pond, river, or seashore is covered with a conventional revetment block, an elderly person or a child may fall into the pond, river, sea, or other shore by mistake, and there is nothing to catch on the shore. You cannot escape from it quickly, which can have unfortunate consequences.

[0005] An object of the present invention is to provide a revetment block that can solve such a problem.

[0006]

[Means for Solving the Problems]

 In order to achieve the above objectives, the revetment block of the present invention will be provided with a hole on the front side for hooking hands and feet.

[0007] When this block is used on the shore of a pond or a river, if the water depth of the shore is large, even if an elderly person or a child accidentally falls on the shore of the pond or river, the old person And children can hang their hands in the hole and grab them on the revetment block, and they can also climb their shore by hanging their feet.

[0008] The above invention is embodied as follows. That is, the cross-sectional shape of the hole is a circle, or a polygon such as a square or a triangle. The hole is provided so as to substantially coincide with the orthogonal center line on the front surface, and has a representative cross-sectional dimension of about 7 cm or more and a depth of about 10 cm or more.

[0009] Furthermore, the front surface is, for example, rectangular, and the length of one side thereof is about 50 cm 2 or less.

[0010]

[Embodiment of the invention]

 FIG. 1 is a view showing one embodiment of the present invention, and FIG. 2 is a view showing another embodiment of the present invention. As shown in FIG. 1, the revetment block of the present invention includes a front part 1 having a rectangular shape in a front view, and an anchor part 2 integrated with the front part 1.

The front part 1 has a horizontal dimension a of about 40 cm, a vertical dimension b of about 25 cm, and a thickness dimension c of about 7 cm. The periphery of the front face 1 a is chamfered, and the central part has an external appearance. A slight dent d is formed to improve the performance.

The anchor portion 2 is extended approximately 40 cm rearward from the center on the rear surface side of the front portion 1, and its outer shape is firmly supported by the ground.

Although the above-mentioned configuration is not different from the conventional revetment block, in the present invention, the front portion 1 is provided with a hole 3 for hanging a hand or a foot. The hole 3 is provided substantially coincident with a center line orthogonal to the front surface 1a, has a circular cross section, a typical diameter of approximately 7 cm or more, and a depth of approximately 10 cm or more. I have.

Here, the provision of the hole 3 substantially in line with the center line orthogonal to the front surface 1a makes the appearance in a front view good, and also makes the overall weight balance good. In addition, the hole 3 having a diameter of about 7 cm or more and a depth of about 10 cm or more is a size convenient for hanging a person's hand or foot.

In the example shown in FIG. 1, the cross-sectional shape of the hole 3 is circular. However, the present invention is not limited to this. For example, the hole 3 may be square as shown in FIG. 2A or may be formed as shown in FIG. 2B. It may be a triangle or the like. At this time, the length of one side, which is a typical dimension of the cross-sectional shape of the hole 3, is about 7 cm or more. In this way, the hole 3 has an appropriate size, and the hand or foot hooked on the corner of the square or the triangle is easily caught in the hole 3.

When manufacturing the product of the present invention, for example, a mold having an overall shape is prepared, and concrete is poured into the mold, whereby the product is efficiently manufactured. In the product of the present invention, the hole 3 reduces the overall volume and weight by about 10 to 15% compared to the conventional seawall black. This decrease reduces the amount of concrete used as material and also makes seawall blocks. To reduce the fatigue of workers who handle

The use of the present invention is performed in the same manner as the conventional revetment block. In this case, the present invention alone may be used to cover the ground of a pond, a river, or a seashore. Articles and conventional revetment blocks may be used to cover it. However, in the latter case, the devices of the present invention must be arranged in a scattered manner so that the other devices of the present invention are located far enough to reach the limbs of the grasped person.

[0018]

[Effect of the invention]

 According to the present invention as described above, if a person accidentally falls into a place with a large depth of water on a shore such as a pond, river, or sea covered with a seawall, even a person who cannot swim can hook his hand into the hole and grab the seawall. It is possible to climb the shore by hanging your toes in a hole, and it is possible to safely escape from the waterside such as a pond.

Further, the presence of the holes can save concrete as a material, and can reduce the total weight, for example, by about 10 to 15%, and can reduce the labor of workers during handling.

According to the second aspect, the characteristic due to the difference in the cross-sectional shape of the hole is exhibited. For example, when the hole is circular, the production by the molding die is compared with the case where it is polygonal. It becomes easy, and if it is square or triangular, the hand or foot will be easily caught in the hole.

According to the third aspect, the position of the hole makes the weight balance and appearance good, and the size of the hole is convenient for hooking the hands and feet.

According to the fourth aspect, the effect of the present invention is obtained because the frequency of use is high and the hole interval becomes appropriate regardless of the position and number of holes when used on the shore. It will be prominently demonstrated.
