Description

[Detailed description of the invention] This invention relates to concrete blocks that are laid on a slope.

Conventionally, as shown in Fig. 1, this type of book has a hexagonal main plate a formed by cutting out the four corners of a rectangular plate, and has a frame raised along the outer periphery, and is connected from the cutout. It is constructed by protruding reinforcing bars C, and the blocks are stacked vertically and horizontally on the slope.
The connecting reinforcing bars C are connected to each other in a joint space surrounded by the cutout portions of each block, and the blocks are joined by filling the space with joint concrete.

However, due to rainwater flowing from above the slope on the surface of the conventional block masonry, dust accumulates on the upper edge of the lower frame of the block, as shown in Figure 2, and the aesthetic appearance of the slope is significantly impaired. I felt regret.

In order to eliminate such defects, the inventors of the present invention have decided to file 1975 Utility Model Registration Application No. 111608 (Utility Model Application No. 111608
No. 8677), a hexagonal main plate is provided with notches perpendicular to the diagonal at each of the four corners of a rectangular plate, and a block is provided with protruding ridges located along the notches at the four corners of the hexagonal main plate. However, this block is made up of a hexagonal main plate with four corners cut out from a rectangular plate, so it is cumbersome to manufacture. Because the reinforcing bars protruding from the cutout must be connected in the void created and joint concrete placed, construction is complicated and difficult, and it is not suitable for locations where the ground is stable or where the slope is gentle. In places where connecting reinforcing bars are not required, it is inevitable that it will be uneconomical.

The present invention has been proposed in order to eliminate such defects, and includes providing protrusions at each of the four corners of the square plate, the inner edges of which are perpendicular to the diagonal line, and The present invention relates to a block characterized in that a low flow area for rainwater, etc. is formed between adjacent end portions of protruding portions.

The block related to this proposal is configured as described above,
The same blocks are laid out vertically and horizontally on a slope.

As described above, the block of the present invention is provided with protrusions at the four corners of the rectangular main plate, the inner edges of which are perpendicular to the diagonal line, and the adjacent ends of the protrusions on each side of the rectangular plate. Since the space between the sections is formed into a low rainwater circulation area, rainwater flowing down from above the slope is mainly absorbed from the low rainwater circulation area between the left and right opposing protrusions on the upper edge of each block. It is guided by the surface of the plate, further guided by the inner edges of the protrusions disposed on the main plate, and guided by the inner edges of the protrusions opposite to the left and right at the lower end edge of the rectangular plate of the falling waist block. Rainwater is guided to the main surface of the lower block from the low flow area between the two protrusions.

At this time, since the inner edges of each of the protrusions are disposed perpendicularly to the diagonal line at the four corners of the main plate, the inner edges are disposed obliquely to the horizontal line on the main plate. As a result, rainwater flowing down the slope is guided by the inner edge of the ridge and flows downward, and there is no risk that debris carried by the rainwater will accumulate on the ridge. This eliminates the risk of spoiling the aesthetic appearance of the slope, which is the case when the conventional blocks are used.

In addition, the block according to the present invention is easy to manufacture because the corners of the rectangular main block are not cut out, and unlike the conventional block, the blocks are formed at the corners of vertically and horizontally adjacent blocks. There is no need to connect reinforcing bars for joints in the space provided and fill with joint concrete, and it is sufficient to simply lay masonry vertically and horizontally on the slope, which greatly simplifies construction.

The present invention will be described below with reference to the illustrated embodiments.

Reference numeral 1 designates a rectangular main plate, and protrusions 2 whose inner edges are perpendicular to the diagonal line are arranged at each of the four corners of the rectangular main plate 1. It is formed in areas where low rainwater flows.

Further, in the center of the main plate 1, there is provided a protrusion 3 in the shape of a truncated quadrangular pyramid, each side of the bottom being parallel to the inner edge of each of the protrusions 2.

゛The protruding portion 3 may be formed into any shape such as a circular tomb or other polygonal tomb.

The blocks A constructed as described above are laid out in rows and columns on a slope B as shown in FIGS. 7 and 8.

As shown by the arrow in Figure 7, the rainwater flowing down from above the slope is mainly flowing from the low rainwater flowing part between the adjacent protrusions 2, 2 on the upper edge of the main plate 1 of block A. It flows down on the main version 1, guided by the central protrusion 3 and the inner edges of the four corner protrusions 2, and flows down on the main version 1, so that the upper edge of the lower block A on the main version 1 is adjacent to the upper edge of the lower block A. The rainwater is guided from the gap between the protrusions 2 and 2 onto the main plate 1 of the block A at the same lower level, and in the same manner, rainwater, etc. flows down the block masonry surface and is carried by the rainwater etc. to the surface of the block A. There is no danger that garbage will accumulate.

FIG. 9 assumes a three-point support test for the block, and the presence of the central protrusion 3 increases the central cross-section of the block A, so that it can sufficiently withstand a large load.

FIGS. 10 to 12 show other embodiments of the proposed blocks. The block A shown in FIG. 10 has a recess 4 cut out on the back surface, and the block A shown in FIG. A retaining piece 5 is provided in a protruding manner, and the central protruding portion 3 is omitted in the block A shown in FIG.
