2. Description of the Related Art Conventionally, as shown in FIG. 13, an embankment 5 is placed on the ground 3.
In this case, in order to prevent ground subsidence due to the embankment load, there is an example in which lightweight foamed resin blocks 1 are stacked to form an embankment structure. There is also an example in which this is carried out as an alternative to the conventional retaining wall structure due to the self-supporting property of the edge portions of the stacked foamed resin blocks 1.

However, the foamed resin block 1 which has been used as a conventional embankment or a self-supporting wall is not integrated as the structure 4, but the foamed resin blocks are simply stacked to form the foamed resin block structure 4, and the upper surface thereof is formed. Only the pavement structure 2 etc. were provided in the above. In this case, the integrity of the foamed resin blocks 1 only depends on the frictional resistance of the contact surface, and there is a risk that the foamed resin block structure 4 may collapse due to an external force exerted on the embankment 5 such as an earthquake or inflow water.

Therefore, the inventors have developed a novel technique of holding the structure of a foamed resin block structure by fixing the foamed resin blocks constituting the structure with a fixture such as a binding metal fitting or a restraint. . By applying this technology to the foamed resin block construction, the foamed resin block construction is integrated, the risk of collapse of the foamed resin block construction due to external force is avoided, and the structural stability of the foamed resin block construction is greatly improved. It will be improved to.

On the other hand, a concrete retaining wall or a masonry retaining wall is laid on the entire surface of a conventional upright embankment surface, and the earth pressure applied to the retaining wall is counteracted by the retaining weight of the retaining wall and the structural member so as to counteract this. Stabilization was planned. The concrete retaining wall, etc., which is placed on the wall surface of the structure, has its structure, that is, the length of the leg portion of the concrete retaining wall, the thickness of the wall portion, in consideration of the falling, sliding, etc. of the portion of the structure receiving the earth pressure. It was complicated because it was necessary to determine the tilt angle.

The complexity of the construction of this construct has been eliminated by applying the above technique. In other words, when constructing a building such as a self-supporting wall with foamed resin blocks and fixing the foamed resin blocks to each other to integrate the construction itself, it is placed on the wall surface of the construction to stabilize the construction because of the self-supporting property of the foamed resin block. Structural facilities such as concrete retaining walls are unnecessary.

However, the wall surface of the foamed resin block structure is expected to be deformed or damaged by direct sunlight or an external force, and from this point, the inventors of the present invention have also conducted research aimed at protecting the wall surface of the structure. .

[0008]

The present invention has been completed as a result of the above research, and it is easy to attach a corrugated plate covering a wall surface of a foamed resin block structure in order to keep the structure in a more stable state. The object is to provide a concrete block for a foamed resin block construction that can be leveled.

[0009]

In order to achieve the above object, the invention according to claim 1 is "concrete which is placed on the wall surface of a foamed resin block structure in which foamed resin blocks are stacked and fixed to each other. The gist of the concrete block is a concrete block for a foamed resin block structure, which is characterized in that the concrete block is formed in an inverted T shape and has bolt holes at its ends. The foamed resin block referred to in the present invention refers to a foamed resin block molded into a specific shape. To fix
It means that the foamed resin blocks are connected to each other so that the foamed resin blocks are not displaced or separated from each other.

[0010]

The concrete block for a foamed resin block structure of the present invention will be described in more detail below with reference to the drawings. The foamed resin block structure of the present invention is formed by stacking foamed resin blocks and fixing the foamed resin blocks to each other.
