[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a block that can be used as a water promenade just by connecting and joining together.
In particular, the present invention relates to a water promenade block structure in which the inside of the block also functions as a place for laying and growing fish.

[0002]

2. Description of the Related Art Seawall protection for rivers, lakes and marshes is effective in most rivers and the like because it is effective in preventing disasters and preventing weathering. Furthermore, since rivers and the like are often places for recreation, there are often cases where a step near the water surface is used as a promenade as a revetment.

[0003]

[Problems to be solved by the present invention] However, conventionally, such a water promenade was constructed by cast-in-place concrete, but since many parts are immersed in the water, the construction becomes very large and requires a lot of labor and time. Was expensive.

[0004] In addition, in the case of fish, which once flourished with aquatic plants and used as spawning and breeding sites, the current environment in which plants were difficult to grow and did not evacuate was very poor, and people strolled along this promenade. Even so, it is supposed that they are just walking on the bare concrete surface while watching the river where fish do not live. Therefore, in the present situation where the destruction of nature has become a social problem, there has been a demand for the development of a product that does not impair the revetment function and can also maintain the natural environment.

[0005]

Means for Solving the Problems In view of the above-mentioned situation, the present inventor has finally made the present invention as a result of intensive research. A rectangular parallelepiped concrete block for forming a water promenade, which has a hollow portion inside, and an opening communicating with the hollow portion is provided on a side surface, and has an upper surface. One ridge is formed with an eave portion extending flush with the upper surface.

[0006] Here, the "water promenade" refers to a sidewalk installed near rivers, lakes and other shores. The required strength is low, unlike seawalls that have the strength to withstand running of trucks and the like. Also, the revetment function does not need to be large, and is basically a facility to be added to existing revetment facilities. It may be provided in contact with and parallel to the revetment wall, or it may be provided so as to protrude from the revetment.

[0007] The block according to the present invention is a unit for constructing the water promenade, and is a promenade if it is continuously provided and joined with mortar or the like. In addition, the revetment is generally rarely perpendicular to the water surface, and is slightly inclined, so that the revetment can be installed along such revetment.

That is, after forming a rectangular parallelepiped, the eaves are extended from one side of the upper surface. The rectangular parallelepiped is used to facilitate connection, and the eaves are provided to facilitate installation along the sloped revetment. When it is installed, a gap corresponding to the inclination is formed on the upper surface side). In addition, the rectangular parallelepiped is originally “a hexahedron in which all adjacent surfaces intersect at right angles”. Since the size and the shape are not limited, the concept of a rectangular parallelepiped includes a rectangular plate having legs extending downward from the four vertices. Of course, a cube is also a part of a rectangular parallelepiped.
Furthermore, although the overall shape is substantially a rectangular parallelepiped, a continuous surface that is in contact with the surface when it is continuously provided is not flush, and an uneven surface such as an interlocking block also belongs to the category of a rectangular parallelepiped. Further, since the eave portion is a portion that becomes a promenade surface together with the upper surface, it is formed flush with the upper surface.

Further, since the frame is made of concrete, it may be difficult to say that it is suitable as a promenade in terms of appearance. In particular, when natural stone is used, the stone is beautiful, and the degree of abrasion caused by walking is smaller than that of concrete alone, so that the stone is hardly deteriorated and is very suitable. Furthermore, if a natural stone or artificial stone is stuck on the front surface, or if a pseudo stone pattern is applied by providing irregularities or rough surfaces on the front side contact part of the construction formwork, When viewed, it is beautiful, so that the landscape of rivers and the like is improved, and moss is easily attached to the surface, which is more suitable for growing fish.

[0010] Further, the block of the present invention has a hollow portion inside in order to secure an area necessary for spawning and growing fish, and an opening communicating with the hollow portion is provided on a side surface. The shape and number of the openings are not limited. However, judging from the habit of general fish, it is better that the hollow portion communicates with the adjacent hollow portion than the independent one, and it can be said that the hollow portion is preferable for the water body itself such as a river.
Therefore, it is better to have an opening in the flow direction of water. The front side is not necessarily required as long as it is in communication with the cavity when the top faces are joined.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in more detail with reference to the embodiments shown in the drawings.

FIG. 1 shows an example of a water promenade block 1 (hereinafter referred to as “the present invention block 1”) according to the present invention.
A flat rectangular upper plate 2, a front plate 3 that hangs at right angles from the front ridge, two vertices of the rear ridge of the upper plate 2, legs 4 and 4 that hang down slightly from the front position, and Front plates 3 and 2
This is a concrete block constituted by a lower plate 5 which is a rectangular portion connecting the lower portions of the two legs 4. Further, the front plate 3 has two openings 6, whereby the cavity 7 of the block 1 of the present invention communicates with the outside on all four side surfaces.

When a portion surrounded by the front plate 3 and the two legs 4 is considered as a rectangular parallelepiped, the lower plate 5 substantially matches the bottom surface of the rectangular parallelepiped, while the upper plate 2 is located behind the top surface of the rectangular parallelepiped. There is an extended part. The eave-shaped portion 21 is provided to prevent the lower side of the block 1 of the present invention from hitting the quay when the quay or the like to be installed is inclined. It is installed continuously so that the shape part 21 side contacts a quay etc. In the case where the eaves-like portions 21 are installed so as to protrude without being along the quay or the like, the eaves-shaped portions 21 may be connected to each other while being in contact with each other (not shown).

In the block 1 of the present invention, a natural stone is worked on the surface of the upper plate 2 and the inside of the mold is worked on the surface of the front plate 3 to cast concrete to form a rough surface and a groove. Thus, the pseudo stone pattern 9 is rendered. The surface treatment of the upper plate 2 is a work in which thinly sliced natural stones 8 are appropriately spread, and are integrated by a method such as temporarily fixing the natural stones 8 to the corresponding portions of the molding die of the main body. Of course, the natural stone 8 may be attached after the main body is completed.

FIG. 2 schematically shows a state where the present invention block 1 is actually laid on the riverbank. The illustrated riverbank is masonry, the surface of which is slightly uneven, and has a curved inclined surface. The block 1 according to the present invention is constructed by a crane or the like (not shown) after the riverbed is leveled, and the mortar 10 is filled in the gap between the joints and the shore to form a promenade.

FIG. 3 shows another example of the present invention. Unlike what has been described so far, there is no portion to be called a "front plate", and the upper plate 2 and the lower plate 5 are divided into four parts. The structure is such that they are connected by the legs 4. Therefore, when the portion surrounded by these four legs 4 is regarded as a rectangular parallelepiped, and the portion connecting the cavity 7 inside the rectangular parallelepiped to the outside is considered as an opening, the opening 6 in this example is very large. It can be said.

FIG. 4 shows still another example of the present invention, in which the opening 6 does not exist as a hole on the front surface 3 side. However, the width of the front surface 3 is smaller than the width of the upper surface 2 so that a gap 11 is formed when the front surface 3 is continuously provided. Although it is not clear from the drawings, the opening 6 is provided on the side surface on the side of the continuous block of the present invention block 1, so that the fish entering from the gap 11 can follow the connecting direction of the present block 1. Can move to the cavity 7 below the adjacent block one after another.

[0018]

As described in detail above, the water promenade block according to the present invention is a rectangular parallelepiped concrete block for forming a water promenade by being continuously provided along the revetment wall. It has a hollow part,
An opening communicating with the hollow portion is provided on each of the four peripheral surfaces, and an eave portion extending flush with the upper surface is formed at one ridge of the upper surface. This is a practically extremely useful device having various effects as described below. Since a promenade can be constructed in addition to the existing revetment facilities, costs can be reduced and the construction period can be shortened. The work is simpler than the cast-in-place method, since it is only necessary to connect the blocks and connect the individual parts with mortar or the like. Since there is an eaves part, it can be installed in contact with the revetment even if it is inclined. There is a cavity inside, and there is an opening communicating with this cavity on the four peripheral surfaces, so that it becomes a spawning and growing place for fish and the like that inhabit the water area. When a rough surface is formed on the front plate surface, the appearance is improved and water moss is easily attached, which is suitable for growing fish and the like.
