Abstract

PROBLEM TO BE SOLVED: To provide a constructing block applicable to a retaining wall, shore protection and a fish nest by opening an upper face part, and composing a hollow block providing with a notch in a part forming both the side faces, and locating a recessed part enclosed with parts for forming each opposed face of both the side faces of the block and the front at a lower position on the front side. SOLUTION: An upper face part is opened to compose a hollow block provided with a through hole 32 on both side face plates 3, 3. A recessed part 25 enclosed with each opposed face and a front plate 2 of both the side face plates 3, 3 of the block is located at the lower position of the front plate 2. The block is laminated by fitting a projection 33 in a recessed groove 34. In the case of laminating, since a recessed part 25 exists, an opened part for the getting in and out of a fish is formed in front of the upper face of each block, and can be utilized for a fish rest block, and in the case of laminating the blocks with staircaselike shift, the opened part can be set up large to be utilized for a planting block. Thus it can be utilized for a sand and stone charging type block and a fish-nest block.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a construction block used for a retaining wall block, a seawall block, a fish nest block, and the like.

[0002]

2. Description of the Related Art Concrete blocks for construction are used in various forms for various works for residential land development, flood control, environmental protection and the like. The use of blocks has many advantages compared to the case of complete on-site construction, such as a shorter construction period, the need for high-level construction work is not required, and many other advantages. The main construction is being carried out by stacking blocks in parallel.

The structure of this block is basically a hollow body having a rectangular parallelepiped shape, although there are many exceptions. In the case of a retaining wall block, etc., the hollow portion is filled with debris, and in the case of a fish nest block, This hollow part is kept as a space and is filled with river water or seawater, and this is where fish live and spawning places. In addition, in the case of a block in which the earth and stone can be put, a large opening portion is not provided in the front plate so that the earth and stone does not fall out from the front surface of the retaining wall after construction. On the other hand, in the case of a fish nest block, it is necessary that the block internal space and the outside can freely enter and exit, so that the front plate portion of the block has an opening as a hole or notch, or the front plate itself is not provided. Like that.

[0004]

However, the blocks for constructing the retaining wall and the blocks for constructing the fish nest have many similarities when judging from the overall shape and the basic construction method in a large sense. Despite this, it was actually a completely different block with no versatility.

[0005] For example, in actual construction, a seawall may be constructed of a hollow block on a hollow fish nest block. In such a case, the connection between the two blocks is often unsuccessful because they are completely different blocks, and in particular, the imbalance due to the difference in design could not be corrected.

Another problem is that the strength of the entire structure is reduced by providing holes or cutouts in the front plate of the fish nest block. In other words, in the case of a fish nest block, not only the internal space and the outside need to communicate with each other, but also the blocks need to communicate with each other. This is because there are holes and notches on the three surfaces. Therefore, conventional holes and notches are small because they are openings that allow fish and water to enter and exit, taking into account the reduction in strength.

[0007]

Means for Solving the Problems In view of the above points, the present inventors have finally made the present invention as a result of intensive research, and the feature of the present invention is that the top face and both side faces constituting a hexahedron are provided. , Front, back, at least both sides out of the bottom, front and back sides are formed on both sides,
There is a front plate and a back plate, and the top surface parallel to the bottom surface is open, and both side plates are integrally formed hollow blocks provided with holes or cutouts that become holes when laminated. Thus, the point that the concave portion surrounded by each opposing surface of the both-side plate and the front of the front plate exists at a position below the front plate.

[0008] That is, the present invention is characterized by the structure of a "frontal slab" which forms the front surface of a rectangular parallelepiped concrete block whose top surface (or top and bottom surfaces) is open. It can be said that

[0009] The "front plate" is a plane if it is a rectangular parallelepiped block, and both sides are vertically contacted with each other via one ridge line. However, in the case of the present invention, it is not a plane. Or, it does not contact both sides perpendicularly through one ridge line. It is characterized in that a concave portion surrounded by each facing surface of the two-sided printing plate and the front surface of the front plate exists below the front plate. Due to the presence of this concave portion, when the building blocks according to the present invention are laminated,
An opening for communicating the block internal space with the outside can be obtained without relying on a means of notching a hole.
Furthermore, if the form of lamination can be adapted to both direct stacking and stepwise, the size of this opening can be changed inevitably, and it can be suitably used as a planting block.

When used as a planting block, in areas where there is a large amount of snow in winter, the accumulated snow blocks the sun and applies a load, creating an environment that is extremely inconvenient for plants. Therefore, it is preferable to make the block structure a structure that makes it difficult for snow to pile up during snowfall, and to prevent it. Specifically, the upper portion of the front plate and the front end surface of the side plate may be formed on the same plane, and the recess at the front lower portion of the front plate may be provided in a form with "hisashi".

The hollow block is not limited to the block of the present invention, and often has a thick portion such as a rib provided for improving the strength of a portion subjected to a vertical load. And the like are actually complicated shapes such as having a radius portion and a protruding portion. Therefore, it is easily expected that an actual product has such a structure also in the building block according to the present invention. In that sense, what is called a front version, a side version, or a rear version does not always have a clear boundary.

[0012]

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

FIG. 1A shows an example of a construction block 1 according to the present invention (hereinafter referred to as the present invention block 1). As is clear from the drawing, the block 1 of the present invention is a substantially rectangular parallelepiped concrete block integrated molded product having an open top and bottom surface. However, the lower part of the part forming the front (hereinafter referred to as the front plate 2) is not perpendicular to the bottom but is inclined. The lower portion of the front plate 2 is inclined, but a portion forming a side surface (hereinafter referred to as a side plate 3) is perpendicular to the bottom surface, so that the front lower portion of the side plate 3 projects forward from the front plate 2. A protruding piece 31 is formed.
In other words, a concave portion 25 surrounded by the side plate 3 exists at a front position below the front plate 2. The front plate 2 is provided with a small hole for draining water, or a concave portion is provided at the top end of the back plate, but both are present in the conventional hollow block. It will not be described here in detail.

As shown in FIG. 1B, the front plate 2 in the illustrated example has a front surface bent, and a front surface 21, a lower surface 22, and a rear wall surface 23 of the hessian portion.
It consists of two faces (sides in the figure). Due to such a bent structure, the block 1 of the present invention, when directly stacked to form a retaining wall, has the front end surface 35 of the side plate 3 and the front surface 21
Together form a single plane, so that the appearance is good. If planting is performed in the recess 25 formed at that time,
Since the eaves are formed, direct sunlight or its reflection is hardly irradiated on the soil surface of the concave portion 25, and the structure is such that strong winds and a large amount of snow can be avoided. When a fish nest is constructed, there is no member projecting from the fish nest surface formed by the entire eaves portion front surface 21 of the block constituting the fish nest. No more disturbing concerns.

The side plate 3 has a through hole 32, which is an opening through which adjacent blocks communicate with each other when the blocks 1 of the present invention are continuously provided. Further, one projection 33 is provided on the upper surface of the side surface plate 3 and three concave grooves 34 are provided on the lower surface, respectively. As well as to prevent displacement in the front-rear direction.

Next, FIG. 2 schematically shows a state in which the blocks 1 of the present invention shown in FIG. 1B are stacked, and the front end face 35 of the side plate 3 constitutes a vertical plane as a whole. It is clarified that the front plate 2 forms the recess 25 so that the opening 4 is formed in front of the open portion of the top surface.

FIG. 3 shows an example of a state in which the vicinity of a revetment is constructed by the block 1 of the present invention. Exactly the same block 1 of the present invention is used as the retaining wall A and the revetment wall B.
It is clear that they are also used as fish nests C and planting slopes D. Since the blocks used are the same, the appearance of unity is very high, and it is easy to apply a unique process to the surface of the front slab to create a unique seawall or the like.

Although the revetment wall B and the fish nest C are constructed by the same block, the block 10 at the lowermost end of the revetment wall B is not open at the bottom and has a bottom plate 5. As a result, the interior space of the block is a space in which debris is put in the revetment wall B, and a fish nest C is a space where fish come and go and where they live. In addition, instead of separately preparing a block having the bottom plate 5, a plate member having a connecting member is fitted into the stacking gap of the block 1 of the present invention described above without the bottom plate 5. It is also possible (not shown).

On the planting slope D, the blocks 1 of the present invention are laminated in a stepwise manner. The deviation width is determined by fitting the projection 33 on the upper surface of the side plate 3 of the block 1 of the present invention into any one of the three concave grooves 34 of the upper layer block, and includes three types including direct stacking. There is a way of loading. However, not only three types of slopes, including vertical, can be selected from the slope obtained by block construction, but the slope can be set steplessly by not setting the bottom surface of the block to be installed parallel to the horizontal plane. FIGS. 4 (a) and 4 (b) schematically show such a case.
4 shows two examples, that is, an example in which the bottom surface is parallel to the horizontal plane (FIG. 9A) and an example in which the bottom is not parallel (FIG. 9B).

The block 1 of the present invention has been described only by way of example in which blocks having the same shape are stacked.
You may combine things from which a shape differs. FIGS. 5A and 5B show one such example.
As is clear from the figure, the block 1 of the present invention having the largest size is placed at the bottom, and a retaining wall is constructed by sequentially stacking smaller blocks thereon. Due to the difference in stacking, a vertical retaining wall is formed in appearance in the case of FIG. 3A, and a planting retaining wall having a step shape is formed in the case of FIG.

FIG. 6 shows a block 1 of the present invention relating to the overall shape.
In this example, the block 1 of the present invention is not a rectangular parallelepiped but has a parallelepiped shape in which the angle between the bottom surface and the side surface is vertical, and the angle between the bottom surface and the front surface 21 of the hessian portion is not vertical. It has become. In addition, since the front plate 2 is formed with the cutting part front surface 21 aligned with the front end surface 35 of the side plate 3 in the same manner as the blocks shown up to now, when the blocks are constructed with these surfaces aligned, a slope is formed. Will be done. For example, when this is used as a planting block in a heavy snowfall area, the slipping of the snow is facilitated by the presence of the front surface 21 of the eaves portion, and the effect that the planted plant is less damaged by snowfall is reduced. In the case of a shape like this example in which the protruding piece 31 is present below the front side of the rectangular parallelepiped instead of the rectangular parallelepiped, the stability (resistance) of the block 1 of the present invention alone and the entire structure increases. . Although the back plate 6 of this example is parallel to the front plate 2 in consideration of the alignment of the back surface during lamination, it is not limited to this, and may be, for example, perpendicular to the bottom surface (not shown). ).

[0022]

As described in detail above, the building block according to the present invention comprises a top surface and both side surfaces constituting a hexahedron,
At least both sides, front and back sides of the front, back and bottom sides, there are a double-sided version, a front version and a back version that form these, and the top face part parallel to the bottom face is open and both sides are open. The face plate is an integrally formed hollow block provided with a hole or a notch serving as a hole at the time of lamination, and a concave portion surrounded by each of the opposing surfaces of the side face plates and the front face of the front plate is positioned below the front plate. The present invention is a highly advanced invention having various effects as described below.

Since the front plate is not provided with holes or cutouts, it can be used for blocks of a type that can contain earth and stones. Since the front plate is inclined, when stacked, an opening is formed in front of the top surface of each block, so that it can be used as a fish nest block. If the stacking form is not directly stacked but is shifted step by step in small steps, the size of the opening can be set large and can be used as a planting block (of course, the opening formed by direct stacking) It is also possible to plant in). Since various types of retaining walls and fish nests can be constructed with the same type of blocks, the design, manufacture and construction can be unified, which is economical.
