DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slope building block used for embankment or revetment.

[0002]

2. Description of the Related Art As a conventional slope building block for a slope, for example, the one shown in FIG. 5 is known. The slope building block B includes a front plate 101, a bottom plate 102, and a rear plate 1
03 and a planter portion 100 formed in a substantially U-shaped cross section, and a back plate 105 is provided behind the planter portion 100 while holding a rear plate 103 and a space 104. In this case, The rear plate 103 and the back plate 105 are flat
The flat plate 106 had a long hole 107 formed therein.

[0003] When the slope building block B is constructed, the rear plate 10 is piled up.
The space 104 between the base plate 3 and the back plate 105 is filled with concrete, and the upper and lower blocks B, B are integrally connected via the concrete flowing into the elongated hole 107.

[0004] Further, when this slope building block B is constructed on a curved slope, the adjacent blocks B, B are adjacent to each other at an angle. For example, as shown in FIG. 5, at the time of the outer curve, the ends of the back plates 105, 105 are abutted with each other at an angle.
A gap T1 occurs between zero. For this reason, a separately manufactured panel is attached to the gap T1.

[0005]

However, the above-described conventional slope building block B has the following problems.

[0006] At the time of construction on a curved slope, no measure has been taken to reduce the gap T1 simply by making the adjacent blocks B, B adjacent to each other simply at an angle. Therefore, there is a problem that the panel attached to the gap T1 becomes large, which is disadvantageous in terms of cost and installation work.

The rear plate 103 and the back plate 105 are
Since the flat plate 106 has the elongated hole 107 formed therein, when the space 104 is filled with concrete, the flat plate 106 blocks the inflow of concrete. For this reason, concrete must be cast every time block B is piled up, for example, block B is piled up one level and concrete is cast, and then block B is piled up one level and concrete is casted. No. Therefore, there is a problem that work efficiency is poor and a construction period is lengthened.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and it is possible to reduce the gap between adjacent blocks when constructing a curved slope. A main object of the present invention is to provide a sloped building block that is advantageous in terms of cost and mounting work by reducing the size of a panel to be mounted in the gap.

[0009] In addition, after the blocks are stacked in a predetermined number of stages, the space between the rear plate and the back plate can be immediately filled with concrete from the uppermost block, thereby improving work efficiency and shortening the construction period. A second object is to provide a slope building block capable of achieving the following.

[0010]

In order to solve the above-mentioned problems, a slope building block according to claim 1 of the present invention comprises:
A front surface, a bottom plate, and a rear plate have a planter portion formed in a substantially U-shaped cross section. Behind the planter portion, a rear plate and a back plate for holding a space are provided. In the block,
Thin portions are formed at both ends from the front plate to the bottom plate and at both ends of the back plate.

According to a second aspect of the present invention, there is provided a slope building block having a planter portion having a substantially U-shaped cross section formed by a front plate, a bottom plate, and a rear plate. In a slope stacking block provided with a back plate while holding a space between the rear plate and the back plate, thin portions are formed at both ends from the front plate to the bottom plate and at both ends of the back plate, and The plate and the back plate are connected by a vertical plate.

[0012]

In the slope building block according to the first aspect, thin portions are formed at both ends from the front plate to the bottom plate and at both ends of the back plate. Therefore, construction on a curved slope, for example, in the case of an outside curve, after removing the thin portion formed at the end of the backboard, butting the ends of the backboard at an angle, The gap generated between the front plates can be reduced. Similarly, at the time of the inside curve, after removing the thin portion formed at the end from the front plate to the bottom plate and then abutting the ends of the front plate at an angle, the gap generated between the back plates Can be reduced.

[0013] When applying to a straight slope that is not curved, adjacent blocks are directly adjacent to each other without stripping the thin portion, and the thin portion is stripped as necessary. Only as described above, it is possible to cope with a curved slope.

According to a second aspect of the present invention, there is provided a slope building block.
The rear plate and the back plate are connected by a vertical plate. Therefore, when filling the space between the rear plate and the back plate with concrete, there is nothing to block the inflow of concrete, and the concrete can flow straight.

Therefore, after the blocks are stacked in a predetermined number of stages, the space between the rear plate and the back plate can be immediately filled with concrete from the top block, thereby improving work efficiency and shortening the construction period. Can be planned.
