BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building block that can be piled up on a slope such as a mountain area or a residential land development site, and has a curved slope or an inclined fan shape. Is also designed to ensure a firm build.

[0002]

2. Description of the Related Art In order to prevent landslides in mountainous areas, residential land reclamation areas, and other slopes, and to improve the appearance of the slope, a hole is drilled at a position 1/4 from the side edge. It is common practice to stack building blocks that have the left and right vertical reinforcing bar insertion holes, and when stacking blocks, the blocks are generally in the form of a pile and are located above. The blocks located below and the blocks located below are laterally displaced by half the width, and vertical reinforcing bars are inserted in series through the reinforcing bar insertion holes that connect the vertically stacked blocks to fill interstitial concrete and cure and cure. And then fix it.

For example, Japanese Utility Model Publication No. 63-
The building block described in Japanese Patent No. 23473 is
A cloth having a projecting portion on the upper surface portion, a receiving groove on the lower surface portion, a reinforcing bar insertion hole formed vertically at a position 1/4 from the side end portion, and a lateral groove portion provided on the back surface. This is an example of blocks that can be stacked, and is effective as a block wall that can be constructed extremely strongly.

[0004]

However, in the above-mentioned conventional block, although it is effective for a mere flat slope, the slope is curved so as to bulge forward or has a fan shape. If so, there is a problem in that the vertical positions of the reinforcing bar insertion holes of the blocks stacked one above the other do not match vertically.

For example, of course the slope of a mountain or the like is such that the upper part of the slope inclines so that the upper part faces rearward, but it is further curved along the lateral direction, and the lateral width of the lower end and the lateral width of the upper end. Is a fan-shaped case where they are different.

[0006] In the slope of the above-mentioned form, it is not possible to simply lay one uniform block,
At the construction site, you have to deal with some of them by hitting them on site. Therefore, not only is the strength of the constructed concrete block wall unreliable, but also the workability is extremely hindered.

SUMMARY OF THE INVENTION The present invention has been proposed in order to solve the above-mentioned drawbacks and problems. In the present invention, an adjacent block main body is provided on the rear surface of a front portion which is in contact with the adjacent block main body. The main body of the block, which has a retaining portion that can hold the gap even if the front portions are in contact with each other, is a long hole in the horizontal direction in the cross section. The left and right sides of the block body are provided with lateral projections on a part of the lateral width of the block body on the upper surface, and the lateral receiving grooves on the lower surface correspond to the aforementioned projections. Provided over the entire length of the construction block, and further, the left and right side end portions of the front surface portion are formed as tapered surfaces inclining rearward and inward so that the lateral width of the block body is shortened. It is a thing.

[0008]

Therefore, when the block main bodies are stacked side by side, since the side end portions of the front surface portion are tapered surfaces inclining toward the rear inside, the side end portions of the adjacent block main bodies are brought into contact with each other. As a result, the surface formed by each block body can be formed to be curved along the left-right direction. In addition, since the reinforcing bar insertion hole has a laterally elongated shape, when the reinforcing bars are vertically inserted between the vertically stacked block bodies, the positioning of the reinforcing bar insertion hole is reliable. . Furthermore, the upper and lower surfaces of the block main body are provided with protrusions along the horizontal direction in a part of the horizontal width, and receiving grooves are provided over the entire length of the horizontal width, so that when the block main bodies are stacked vertically. The protruding portion fits in the receiving groove to stabilize the upper and lower stacked states of the block and to change the stacked state.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the embodiments of the drawings. The concrete block body 1 of the present invention
Is on the rear surface of the front part 2 in the shape of a slab whose surface is treated with makeup,
The block body 1 has a horizontal width of 600 to 1 and is formed by integrally forming a reserve portion 3 having a width slightly shorter than the front surface portion 2.
500 mm, height is 500-800 mm, depth of front part 2 is 50-120 mm, width of reserve part 3 is 500-1200 mm, depth of reserve part 3 is 300-880 mm, block The entire depth of the main body 1 is 350 to 10
The range of about 00 millimeters is freely set according to the purpose of use and application.

A pair of left and right reinforcing bar insertion holes 4 are vertically formed in the block main body 1 at a predetermined interval. The reinforcing bar insertion holes 4 are a quarter of the width of the block main body 1 in cross section. It is a hole that is long in the lateral direction to a certain extent, and has a reverse taper shape in which the lateral width at the upper end is longer than the lateral width at the lower end. The center of each of the reinforcing bar insertion holes 4 described above is formed from the side end part 5 of the front surface part 2 to a position of a quarter of the lateral width of the block body 1, and the distance between the centers of the left and right reinforcing bar insertion holes 4 is set. It is desirable that the width be about half the width of the block body 1. Further, although the reinforcing bar insertion holes 4 described above are provided at the base end of the retaining portion 3 in the illustrated embodiment, they may be provided at the front surface portion 2.

On the upper surface of the block body 1 described above, a protrusion 6 is provided in the space between the left and right reinforcing bar insertion holes 4 along the lateral direction, and on the lower surface, a position corresponding to the protrusion 6 is provided. We will set up a horizontal course 7. Since the above-mentioned protruding portion 6 is as long as the distance between the left and right reinforcing bar insertion holes 4,
It is a part of the lateral width of the block body 1, and the receiving groove 7 is formed along the entire length of the lower surface of the block body 1. However, the protrusion 6 may be shorter than the interval length of the reinforcing bar insertion hole 4 described above. Further, the protrusion 6 is formed on the lower surface of the block body 1 in a part of the lateral width, and the lecture 7 is the block body 1
You may form in the full length of the upper surface part of. Therefore, when the block bodies 1 are vertically stacked, the protruding portions 6 of the block body 1 located on the lower side and the block body 1 located on the upper side 6
And the receiving groove 7 are fitted to stabilize the stacked state of the upper and lower block bodies, and since the projecting portion 6 is a part of the lateral width of the block body, the front portion 2 of the block body 1 located on the lower side is An angle difference can be provided between the surface and the surface of the front part 2 of the block body 1 located above. This angle difference is determined by the dimensional difference between the projecting portion 6 and the receiving groove 7 and the length of the projecting portion 6.
The larger the difference from the outer dimensions of the above, and the shorter the lateral width of the protruding portion 6, the larger. In an extreme case, if the protrusion 6 is hemispherical, the angle difference between the surfaces of the lower block body 1 and the upper block body 1 can be 90 degrees.

The left and right side end portions 5 of the front portion 2 are
Since the block main body 1 has a taper surface that inclines rearward and inward so that the width becomes gradually shorter, when the block main bodies 1 are arranged side by side, the side ends 5 of the block main bodies 1 that are horizontally adjacent to each other are brought into contact with each other. As a result, the surface formed by each block body 1 can be formed in a state of being gently curved along the lateral direction. Also, the adjoining spare parts 3
Since they maintain a sufficient gap even when the front surface portions 2 are in contact with each other, they can be installed side by side even on a slope with a large curvature, and along the sloped surface that is curved so as to project forward. However, they can be installed side by side. The bending state when the block main bodies are arranged side by side can be freely selected depending on the inclination angle of the side end portion 5 and the dimensions of the projecting portion 6 and the receiving groove 7 of the block main body 1 described above.

FIG. 8 shows a state in which a block wall 1 is constructed by laminating the block main body 1 of the present invention on the slope which has become a part of the truncated cone-shaped surface. As described above, in the truncated cone-shaped block wall a, since the lateral width of the lower end is longer than the lateral width of the upper end, the block body 1 having a relatively long lateral width is used in the lower portion, and a part of the block main body 1 is wider than that. The block main body 1 having a slightly short width is interposed to adjust the overall horizontal length, and the block main body 1 having a relatively short width is mainly used in the upper portion.

For example, in the block wall a, the lowermost block row b1 is formed by sequentially arranging three blocks having a width of 1500 mm and one block having a width of 1200 mm in parallel, and the second block row b2 from the bottom is 15
Blocks of 00 mm and blocks of 1200 mm are alternately arranged in parallel, and the third block row b3 from the bottom is composed of one block of 1500 mm and two blocks of 1200 mm in parallel in order. Block row bn- located at the second position from the top
1 is 3 blocks with a width of 1000 mm and 60
One block of 0 mm is alternately arranged in parallel, and the block row bn located at the uppermost stage is composed of blocks of 1000 mm and blocks of 600 mm alternately arranged in parallel. In this way, blocks having different horizontal widths are appropriately used to form a horizontal block row, and by stacking the block rows upward, it is possible to form a fan shape as a whole. In this case, since the reinforcing bar insertion hole 4 of each block main body 1 has a long horizontal width, even if the block main bodies having different horizontal widths are appropriately stacked,
Since the reinforcing bar insertion holes 4 of each block body are communicated in the vertical direction, the vertical reinforcing bars 8 can be inserted to fill the filling concrete.

Further, the block main bodies 1 which are laterally adjacent to each other
As described above, the angle of the surface can be adjusted by the taper surface of the side end portion 5 of the block body 1 and the relationship between the protrusion 6 and the receiving groove 7, so that the block wall a as a whole is fan-shaped and arc-shaped. A surface can be constructed. Moreover, if the block rows of each stage are formed into a straight line in the horizontal direction, the block wall a
Is fan-shaped and has a flat surface. The block wall a
The gravel or the like is filled between the back surface and the slope and in the space between the retaining portions 3 of the left and right block bodies 1.

The present invention has been described above based on the embodiments of the drawings. However, the present invention is not limited to the above-mentioned embodiments, and the present invention is not limited to the embodiments described below unless the configuration described in the scope of claims for utility model is changed. It can be carried out at any time.

[0017]

In summary, according to the present invention, the block main body having the front portion and the back portion integrally projected to the rear surface of the front portion is provided with a longitudinal reinforcing bar insertion hole which is a long hole in the horizontal direction in the cross section. Is provided on the left and right, and a horizontal protrusion is provided on the upper surface or the lower surface in a part of the horizontal width of the block main body.
A lateral receiving groove is provided on the lower surface or the upper surface along the entire length of the width of the block main body so as to correspond to the above-mentioned projecting portion. Since it is characterized in that it becomes a tapered surface that inclines toward the rear inward so as to be short, no matter what shape the slope is, the inclined state, or the curved state,
The block bodies can be stacked sufficiently corresponding to their slope conditions, and the block wall can be formed by firmly and firmly stacking and constructing. Also, when the block main body is constructed by stacking, vertical rebars can be surely inserted, and the protrusions can be surely fitted into the receiving grooves, so that the block wall is stable and has sufficient strength. It will be possible to build it, and it will be of high practical value.
