Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a concrete block formed on a side surface such as a side gutter where a sidewalk or a roadway is laid underground with at least an upper surface exposed.

[0002]

2. Description of the Related Art Conventionally, this type of concrete block molded body includes, for example, a step block, a boundary block of a roadway, a gutter and an L-shaped lid of the gutter, and the like. When laying, it is buried first.

[0003] Next, when these concrete block moldings are buried, the work of laying a road or a sidewalk is started. During this laying work, a crushed stone layer or a slab layer, a gravel layer, a concrete layer, an asphalt layer, and the like are sequentially deposited on the excavated ground surface.

In forming each of these layers, the deposition thickness of each layer varies depending on the area in which the layers are to be laid and the use conditions. When the specified thicknesses are determined, a predetermined section is required to lay the layers at the specified thickness (level). Stand a pair of piles inside,
Stretch the string horizontally at a certain height position corresponding to the thickness of each layer,
Each layer was laid based on this string.

[0005]

However, when determining the thickness of each layer as described above, when laying in a predetermined section based on a string of a level corresponding to the thickness of each layer, when setting the level, Since the thickness of the layers was determined in order based on the excavated ground surface, more construction man-hours were required than necessary, which was a factor of extending the construction period.

[0006] However, even if the leveling is carried out by using the man-hours, the depth of the ground surface to be excavated is not always accurate. Occurs.

For this reason, an error occurs in the upper surface of the asphalt layer or the concrete layer laid as the uppermost layer with respect to the reference surface (for example, the upper surface) of the concrete block molded body previously buried. It is adjusted by the asphalt layer or concrete layer laid on the top layer.

[0008] In this case, there is a possibility that the thickness of the essential uppermost layer varies, and when used for a long period of time, cracks may occur on the surface of the portion that cannot bear the weight.

On the other hand, when a buried concrete block molded body is repaired on a road or a sidewalk laid on a side surface thereof or when a concrete block molded body is excavated, it is excavated to a predetermined depth. In order to know the thickness in advance, a method has been adopted in which a hole is excavated in a predetermined place such as asphalt to check the thickness of the layer before excavation work.

[0010] As described above, when confirming the spot-like thickness at a specific narrow place, the thickness differs depending on the place where it is laid, and the prediction of the excavation depth is incorrect, which is a factor that hinders workability.

According to the present invention, there is provided a crushed stone or crushed stone layer, a gravel layer, a concrete layer or an asphalt layer based on a level line formed on a side surface of a concrete block molded article. It is an object of the present invention to provide a concrete block molded body in which the thickness of each layer to be laid is accurately and easily set, the efficiency of laying work is improved, and the construction period can be shortened.

[0012]

In order to achieve the above object, a concrete block molded article according to the present invention is a concrete block molded article buried in a ground where a road or a sidewalk is laid at least with its upper surface exposed. A substantially linear level line is formed in parallel at a predetermined interval on a side surface of the concrete block formed body. According to this feature, on the side surface of the concrete block molded body, straight level lines are formed parallel to the upper surface or the lower surface at predetermined intervals, so that the crushed stone layer or the crushed stone layer, the gravel layer, the concrete layer Alternatively, the thickness of the asphalt layer or the like can be accurately and easily set, the number of laying work steps can be reduced, and the construction period can be shortened.

The molded concrete block of the present invention comprises:
It is preferable that the level lines are displayed in different colors in units of the level lines. In this way, the reference line of each concrete block molded body is not mistaken.

[0014] The molded concrete block of the present invention comprises:
It is preferable that the level lines have position indicating means on the side surface of the block molded body to indicate the position of each level line with reference to the upper surface of the block molded body. By doing so, the position of the level line can be confirmed by looking at the position display means, which makes it easy to confirm how many layers are already buried.

[0015] The concrete block molded product of the present invention comprises:
The position display means is a graphic display that is at least line-symmetric with respect to a virtual center line, and is formed in a similar shape based on the upper surface such that an end of the graphic on the virtual center line is in contact with each of the level lines. It is preferable to do so. By doing so, the figure is displayed in a graphic display that is at least line-symmetric with respect to the virtual center line with respect to the upper surface, so that the position where the graphic edge contacts can be easily estimated, and the position of the level line can be confirmed. This makes it easy to check how many layers are already buried.
