Description

  The present invention relates to a lightweight embankment structure constructed by stacking foamed resin blocks in multiple stages on the ground.

  As a conventional lightweight embankment structure, a foamed resin block with a wall material made of lightweight mortar integrally attached to only one of the four side surfaces of the main body block is used. The thing of the structure which piles up in multiple steps and constructs a wall surface structure is known while installing in line.

  The construction of such a lightweight embankment structure is shown in FIG. 8 in order to prevent deterioration of the block due to the exposed surface of the foam resin main body block after the construction of the foam resin block on the ground is completed. As described above, as a joint treatment between the wall surface material 102 attached to the main body block 101 of the foamed resin block 100 and the wall surface material 102 of the foamed resin block 100 adjacent to the top, bottom, left, and right, between the end portions of the wall surface materials 102 and 102. After a rod-shaped foam material 104 called a backup material is pushed into the joint 103, the surface of the foam material 104 is filled with a liquid sealing material 105 to fix the foam material 105 to the joint 103 (for example, patents).

In the conventional construction method, since the joint treatment is performed, after the construction work of the foamed resin block is completed, a working scaffold must be newly installed along the foamed resin blocks stacked in multiple stages. It took time and effort.
Also, if it takes time to install the work scaffolding and start the joint treatment after the completion of the foam resin block laying work, the exposed joints will become dirty or the surface will deteriorate due to direct sunlight. There was a possibility that water drops due to rain, morning dew, etc. impregnate the joints and cause poor adhesion, resulting in variations in construction quality.
Furthermore, the wall structure has a structure in which a plurality of foam resin blocks are stacked substantially vertically, and the joint treatment is only a foam material fixed on the joint around the wall material. Since the material does not have a function of fixing the material, there is a problem that the fall of the wall material cannot be suppressed when a force in the direction of peeling the wall material is applied for some reason.

  In view of such problems of the prior art, the present invention forms joints in parallel with the laying operation of the foamed resin block in forming the wall structure using the foamed resin block to which the wall material is integrally attached. The wall structure is robust with the ability to prevent the foamed resin block from deteriorating by reliably closing the joint by joint treatment, and to prevent the wall material from peeling off. It is an object to have a simple configuration.

In order to solve the above problems, the present invention provides a foamed resin block in which a wall surface material is integrated with a side surface on one side of a main body block, and the direction of the surface on which the wall surface material is attached is aligned in the same direction. In a lightweight embankment structure constructed and stacked in multiple stages on it,

In this joint cover material, the insertion surface portion inserted in the overlapping portion of the main body blocks on both sides of the joint portion is fixed to the surface of the main body block by the fixing means provided on the insertion surface portion and fixed to the joint portion. Thus, the seam portion is covered with the cover surface portion that overlaps the outer surface of the edge portion of both wall surface materials across the wall surface material on both sides of the seam portion .

The lightweight embankment structure having the above-described structure includes a plurality of foamed resin blocks obtained by integrating wall materials on one side surface of the main body block, and a joint portion between the foamed resin blocks when the foamed resin blocks are arranged in a row . It is inserted into the overlapping part of the main body block of the foamed resin block on both sides of the band-shaped cover surface part that spans the wall material on both sides and overlaps the edge part of both wall material and the seam part, and is fixed to the surface of the main body block Using a joint cover material that is configured by integrally providing an insertion surface portion on the back surface of the cover surface portion,
