Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to a retaining wall concrete block that can be used for general roads, farm roads, forest roads, earth retaining works for residential land development work, revetment work, and hillside work.

[0002]

[Prior art]

 Conventionally, a T-shaped block structure has been known as a concrete block for this type of retaining wall. In this T-shaped block structure, T-shaped blocks are stacked on a basic block to form a retaining wall. At that time, since each stacking block has a T-shaped back plate on the back surface, it is stably supported by the back embankment.

Further, since reinforcing bars are arranged along the T-shaped block back plate, the strength at the time of installation is further improved.

[0004]

[Problems to be solved by the device]

 However, although the above-mentioned conventional concrete blocks for retaining walls are excellent in vertical strength, no consideration has been given to the connection of the left and right blocks, and the connecting parts are misaligned, which makes them unattractive. However, there was a danger that the relevant part would collapse.

Further, reinforcing the portion with a reinforcing bar or the like also has a drawback that the installation work takes too much time and a sufficient reinforcing effect cannot be obtained.

This invention is intended to eliminate the above-mentioned drawbacks, and the right and left blocks are surely connected to each other to provide a good-looking appearance, and there is no danger that the relevant parts will collapse or the like. It is intended to provide blocks.

[0007]

[Means for Solving the Problems] That is, the concrete block for a retaining wall of the present invention comprises a flat board, and connecting plates which are provided on the backs of the left and right ends of the flat board so as to project substantially at right angles to the flat board. This is a concrete block for a retaining wall, which comprises a flat substrate and a hollow plate that protrudes at a substantially right angle in the approximate center of the back surface of a flat substrate. By connecting and forming hollow portions also between the connecting plates, reinforcing bars are respectively arranged in the hollow plates and between the connecting plates.

[0008]

[Action]

 In the concrete block for a retaining wall of the present invention configured as described above, the left and right blocks are securely connected to each other, and the retaining wall has a good appearance, and there is no danger that the relevant portion will collapse. We can provide concrete blocks for use.

Further, even when the portion is reinforced with a reinforcing bar or the like, it is possible to provide a concrete block for a retaining wall which can be easily installed on site and has a sufficient reinforcing effect.

【Example】

 An embodiment of a concrete block for a retaining wall of the present invention will be described below with reference to the drawings.

In FIG. 1 to FIG. 3, reference numeral 1 denotes a flat plate substrate having a hole 2 for draining water in the center thereof. The flat plate substrate 1 is connected to the left and right ends of the back face at substantially right angles to the flat plate substrate 1. The plate 3 is projected. The connecting plate 3 has a concave portion 4 formed on the outer side surface thereof, and a bolt hole 5 formed at the root portion thereof.

On the other hand, a hollow plate 6 is provided substantially at the center of the back surface of the flat plate-like substrate 1 at a right angle to the flat plate-like substrate 1 similarly to the connecting plate 3, and the hollow plate 6 extends along the length direction thereof. A flat hollow portion 7 is provided. This hollow portion 7 has a closed cross-sectional shape in the middle in consideration of ease of demolding from the mold, work for inserting reinforcing bars and the like, and flow of concrete to be filled.

Since the concrete block 11 for the retaining wall having the above structure is configured in multiple stages according to the height of the retaining wall, it is possible to use a plurality of sizes in which the connecting plate 3 and the hollow plate 6 have different lengths. It is necessary to. It is desirable that the connecting plate 3 and the hollow plate 6 provided on the back surface of each flat substrate 1 have substantially the same length.

When using the concrete wall 11 for retaining walls, as shown in FIG. 4, the concrete blocks 11 for retaining wall having long connecting walls 3 and hollow plates 6 are connected to each other on the foundation block 12. The plate 3 is connected using bolt holes 5 by joining them with bolts and nuts. On the upper step is a slightly shorter retaining wall concrete block 11 'of the connecting plate 3 and the hollow plate 6, and on the upper step is a shorter retaining wall concrete block 11 "of the connecting plate 3 and the hollow plate 6. Pile up.

Since hollow portions similar to the hollow plates 6 are also formed between the connecting plates 3, the reinforcing bars 13 are provided in the hollow portions 7 of the hollow plate 6 and between the connecting plates 3, respectively. Arrange. The reinforcing bars 13 are arranged so as to intersect with each other between the retaining block concrete blocks 11, 11 'and 11 "in each stage. In the figure, the prosecution block 12 and the retaining block concrete block 11 in the lower stage are shown. Reinforcing bars 13 are arranged so as to intersect with each other.Of course, depending on the height of the retaining wall, each of the concrete blocks 11, 11 'and 11 "for the retaining wall may have the same size. It is also possible to stack them.

FIG. 5 shows another example of the use of the retaining wall concrete block, and shows a case where the retaining wall concrete blocks 11 ′ and 11 ″ are installed at an inclination.

That is, the concrete blocks 11 ′ and 11 ″ for the retaining wall are installed on the inclined surface 14 formed on the upper surface of the foundation block 12 ′, and the inside of the hollow portion 7 of the hollow plate 6 and the connection plate 3 are connected. By arranging the reinforcing bars 13 in each of the hollow portions, the retaining wall surface can be inclined and constructed.

With the above-mentioned structure, the connecting portion between the concrete blocks for the retaining wall will not be displaced, and the risk of falling down at the location can be prevented.

Further, when reinforcing the connecting portions between the concrete blocks for the retaining wall with reinforcing bars or the like, the installation work was simple, and a sufficiently satisfactory reinforcing effect was obtained.

[0020]

[Effect of device]

 In the concrete block for a retaining wall of the present invention configured as described above, the left and right blocks are securely connected to each other, and the retaining wall has a good appearance, and there is no danger that the relevant portion will collapse. We can provide concrete blocks for use.

Further, even when reinforcing the relevant part with a reinforcing bar or the like, it is possible to provide a concrete block for a retaining wall which can be easily installed on site and has a sufficient reinforcing effect.
