Abstract

(57) [Summary] [Purpose] Any bending angle can be accommodated without making a special block or connecting metal fitting to match the bending angle at the site, and the connecting metal fitting is used just like the straight part. To provide a retaining wall block that can be firmly connected. [Structure] In an L-shaped, U-shaped, B-shaped retaining wall block having a vertical wall portion and a bottom slab portion, two block pieces can be connected and integrated with a flexible band embedded in the vertical wall portion to be freely bendable. It is a retaining wall block characterized by being formed in. The flexible band is a band made of a material that can be easily deformed and bent, such as rubber or metal, and is embedded over the entire length or a part of the vertical wall portion.

[Industrial applications]

 INDUSTRIAL APPLICABILITY The present invention is a retaining wall block suitable for use in an L-shaped, U-shaped, B-shaped retaining wall block having a vertical wall portion and a bottom slab portion, and particularly for a bent portion such as a corner portion. Regarding

[0002]

[Prior Art]

 BACKGROUND ART Conventionally, a retaining wall has been constructed by continuously laying a large number of L-shaped, U-shaped or B-shaped retaining wall blocks each having a vertical wall portion and a bottom slab portion. Since this method produces blocks in a factory, it is said that the site work is significantly reduced, the work efficiency is excellent, and the cost is low. When construction must be performed along a curve or at corners, the blocks must be connected at an angle rather than in a straight line. For corners that bend 90 degrees, special blocks for corners are also manufactured and dealt with, but it is rather rare to bend at 90 degrees, and in most cases other than 90 degrees. Is the angle. In such a case, the bending angle is measured at the site and the connecting metal fitting suitable for the angle is manufactured to connect the blocks, or the construction is performed without using the connecting metal fitting.

[0003]

[Problems to be solved by the device]

 As described above, it is extremely complicated to measure the bending angle at the site and manufacture the connecting metal fittings corresponding to the angle, especially when a large number of different angles have to be manufactured such as curve construction. Greatly affects work efficiency and cost. If the connecting metal fittings are not used, the strength naturally becomes weak, and after the construction, the pressure tends to shift to the connecting part due to earth pressure or uneven settlement, causing misalignment and unsightly.

[0004]

[Means for Solving the Problems]

 The present invention relates to an L-shaped, U-shaped, B-shaped retaining wall block having a vertical wall portion and a bottom slab portion, in which two block pieces are connected and integrated by a flexible band embedded in the vertical wall portion. It is a retaining wall block characterized by being made flexible and bendable. The flexible band is a band-shaped member made of a material such as rubber or metal that can be easily deformed and bent, and is embedded over the entire length of the vertical wall portion or in part thereof.

[0005]

[Action]

 In the retaining wall block of the present invention, two block pieces are connected and integrated by a flexible band embedded in a vertical wall portion. Therefore, by bending the flexible band portion, each block piece can be mutually bent at an arbitrary angle. You can Therefore, it is not necessary to measure the bending angle of the site to manufacture the connecting fitting, and the block can be bent and laid according to the angle of the site.

【Example】

 Hereinafter, the present invention will be described in detail with reference to the drawings illustrating an embodiment. FIG. 1 is a perspective view of a retaining wall block 1 as one embodiment of the present invention, FIG. 2 is a central longitudinal sectional view of the retaining wall block 1, FIG. 3 is an explanatory diagram showing an example of construction of the retaining wall block 1, and FIG. 10 is a central vertical sectional view of a retaining wall block of another embodiment, and FIG. 5 is a central vertical sectional view of a retaining wall block 20 of still another embodiment.

As shown in FIG. 1, the retaining wall block 1 has a structure in which two block pieces 1 a and 1 b are connected and integrated by a flexible band 4. The block pieces 1a and 1b are formed in an L shape by the vertical wall portion 2 and the bottom plate portion 3, and are connected and integrated by a flexible band 4 embedded in the vertical wall portion. On the outer end surface of the vertical wall portion, two connecting fittings 5 are provided on each side, for a total of four. A notch surface 6 is formed near the connecting portion connected by a flexible plate, and it has a V-shaped notch shape when viewed from above, so that it does not interfere with bending at the flexible band. There is. Such notches are appropriately formed depending on the purpose of use of the block and the required bending angle. The flexible band 4 is embedded in the retaining wall block 1 before the concrete hardens when it is manufactured. The flexible band 4 is made of a thin stainless plate, and both ends are bent into a hook shape so that tensile force acts Even so, it is hard to come off from the concrete. In this embodiment, as shown in FIG. 2, the flexible band 4 is embedded over the entire length of the vertical wall portion 2, but it does not necessarily have to be the entire length and may be one portion.

When the retaining wall block 1 is used for curve construction, as shown in FIG. 3, the flexible band 4 is bent and laid at a bending angle suitable for the site. Since the connecting portion 7 can be connected in a straight line in close contact with each other, the connecting metal fitting does not need to be special, and the one used for normal linear construction can be used.

FIG. 4 shows the present invention applied to a B-shaped retaining wall block. The retaining wall block 10 has a vertical wall portion 11, a bottom plate portion 12 and a floor plate portion 13 and has an O shape. The two block pieces having such a shape are connected and integrated by the flexible band 14 embedded in the vertical wall portion. FIG. 5 shows the present invention applied to a U-shaped retaining wall block. The retaining wall block 20 comprises a vertical wall portion 21, a bottom slab portion 22, and a floor plate portion 23, which are U-shaped. Two block pieces having such a shape are connected and integrated by a flexible band 24 embedded in the vertical wall portion.

[0010]

[Effect of the device]

 Since the retaining wall block of the present invention can be bent at any angle by bending it with a flexible band, it is not necessary to manufacture a special block or connecting fitting according to the bending angle of the site, and the laying work is easy. is there. The connection can be firmly connected using the connecting metal fittings just like the straight part.
