2. Description of the Related Art Conventionally, in the construction or rehabilitation of a building such as a road or a platform for a railway station, a narrow area of a limited area is secured in a heavy traffic of people and vehicles.
The existing facilities were destroyed, and then embankments and rebars were assembled to construct new structures mainly composed of concrete. Therefore, large-sized transportation equipment cannot be used in construction work under such circumstances, and therefore, transportation of crushed material such as earth and sand or concrete in the rehabilitation area, or the use of materials such as concrete hardening forms, etc. Transportation work has to rely on human power. In addition, the conventional method of hardening with concrete requires several days to obtain concrete of the required strength, so the construction period becomes longer, and the traffic and traffic safety of people and vehicles during that period are increased. We had to give due consideration to it. Therefore, in order to shorten the construction period, some of the present inventors
A method of stacking and constructing foam resin blocks instead of embankment and concrete casting ( Japanese Utility Model Publication No. 4-33714 )
Suggested.

[0003]

However, even when foamed resin blocks are piled up and constructed, the foamed resin blocks are exposed on the top and side surfaces of the stacked structure, which is the surface layer of the structure. It is necessary to construct a surface layer material.For example, in the case of a platform for a railway station, on the upper surface portion, a floor layer made of a cement hardened material and a further floor layer thereon for transporting heavy loads and frequent movement of people. Forming a surface material layer such as asphalt,
In order to increase the strength of the train against foreign matters such as heat and gravel of a train, a wall member such as a concrete plate or a sheet pile must be installed, which is troublesome. The present invention solves the above-mentioned conventional problems in the above-mentioned foamed resin block stacking method, and very simply constructs a surface layer material on the upper surface and side surfaces of the foamed resin block stacked structure, or newly. It is an object of the present invention to provide a structure using a structural member for civil engineering and building, which can form a surface layer such as a floor or a wall of a building without performing construction.

[0004]

That is, the first aspect of the present invention.
It is one surface of the foamed resin block, with cement cured layer are laminated in less <br/> least a portion of the second surface or third surface
The cured cement layer is reversed with respect to the foamed resin block.
Civil and architectural structural members integrated by tapered joining means are stacked so that the hardened cement is located on the surface, and a foamed resin block without a hardened cement layer is stacked inside. The second aspect of the present invention is the civil engineering / building structure described above, wherein a floor member is formed on the upper surface of the structural body.

Hereinafter, the present invention will be described in more detail with reference to the drawings. As shown in FIG. 1, a structural member 1 for civil engineering and construction used in the present invention has a foamed resin block 2 provided with a hardened cement layer 3 on at least one surface. Here, the block means any shape as long as it can be stacked substantially without gaps by arranging or stacking a large number of them, or further combining other foams of the same or different shape on or in the middle. It may be. The simplest shape of the block is a cube, a rectangular parallelepiped, or the like. Further, two opposing surfaces may be inclined in parallel, or may have a phase structure.

The foamed resin block 2 constituting the structural member 1 for civil and architectural use used in the present invention can be formed of various foamed resins. Examples thereof include polystyrene, polyethylene, polypropylene, polyurethane, A foamed resin such as polyvinyl chloride can be used. Generally, the foamed resin block 2 preferably has a density of 0.01 to 0.05 g / cm3.
Although the size is not particularly limited,
For example, 100-200cm in height, 50-100cm in width, thickness 5
0-100cm is good. It is preferable that the foam of such a foamed resin block 2 has cells independent from a water-resistant surface and a strength surface.

The cement hardened material layer 3 constituting the structural member 1 for civil engineering and construction can be formed of a water-hardened material of various cements such as concrete and mortar. As the hydraulic cement, for example, ordinary Portland cement is used. Portland cement, such as Portland cement, moderate heat Portland cement, early strength Portland cement, low sulfate Portland cement, white Portland cement, hydraulic lime, Roman cement, natural cement, alumina cement, blast furnace cement, silica cement, expansion cement,
There are colored cements and the like. Among these, Portland cement, hydraulic lime, natural cement, blast furnace cement,
It is preferable to use expanded cement and colored cement.
Also, various aggregates, reinforcing materials, lightening materials, water glass, and the like can be added to the cement. As aggregate,
There are ordinary aggregates such as silica sand and silica foam, and artificial lightweight aggregates such as expanded clay, perlite and expanded slag. Examples of the reinforcing material include various organic and inorganic fibers such as slag fiber, carbon fiber, nylon, and polyester fiber. Examples of the lightening material include foamed particles of a resin such as polystyrene resin, polyvinyl chloride resin and polypropylene resin having a density of 0.008 to 0.1 g / cm3 and a particle size of 2 to 15 mm. In particular, when foamed resin particles are mixed into the hardened cementitious material layer 3, it is lightweight and has excellent heat insulating properties. In addition, when constructing asphalt as a surface material when constructing a railway platform or a road, cement is used. The foamed resin particles present on the surface of the hardened material layer are melted by the heated asphalt, and as a result, asphalt enters the holes of the particles after melting, and the adhesiveness between the asphalt and the cement hardened material layer is excellent. Become. The mixing ratio of the expanded resin particles is usually 0.2 to 30 parts by weight based on 100 parts by weight of cement. The thickness of the cement hardened material layer 3 is usually 2 to 15 cm.

As shown in FIG. 2, when the structural member of the present invention is provided at the corner of the structural body, the cement hardened material layer 3 has the upper surface portion and one side surface portion of the foamed resin block.
It may be provided on the surface. Further, the cement hardened material layer 3 may be provided on three surfaces, that is, the upper surface portion and the continuous two side surface portions of the foamed resin block, for the upper corner of the structure.

In order to manufacture the structural member 1 for civil engineering and building,
The foamed resin block 2 may be placed in a mold, and an uncured cement mortar may be poured, cured, and cured to form a cured cement layer 3. Conversely, the cured cement layer 3 may be formed by suppressing and curing the foamed resin block 2 from above the cement mortar placed in a predetermined amount in the mold frame.

[0010] Alternatively, the foamed resin block 2 and the cement hardened material layer 3 may be separately prepared, and the two may be integrated using an adhesive. As shown in FIGS. 1 and 2, for example, as shown in FIGS.
It is preferable that the cured product layer 3 is not separated if it is integrated by a reverse taper type joining means. Such a structure can be easily obtained by providing a concave portion having an inverse taper when molding the foamed resin block 2 in advance, and integrating and curing the cement mortar.

When a wall member such as a sheet pile or a concrete plate is provided further outside the hardened cementitious material layer 3 located on the side surface of the structure, as shown in FIG. What is necessary is just to make it the structural member for civil engineering / architecture in which the receiving jig 4 for fixing the wall member is embedded in the material layer 3. Jig 4
Can be freely selected by a fixing jig for a wall member provided on the outside. Further, the number of the cement hardened material layers 3 may be any number, but is usually 1 to 2 or more. By using the receiving jig 4, the wall member provided outside the hardened cement material layer 3 can protect the inner foamed resin block 2, so that the hardened cement material layer 3 in this case is It is not necessary that the resin block 2 be laminated on one entire surface. That is, it is sufficient that the area has an area in which the receiving jig 4 that can fix the outer wall member can be embedded. However, even if the cement hardened material layer 3 is too small, the strength will be weakened on the contrary, so that an appropriate size must be selected.

As shown in FIGS. 4 and 5, when constructing a platform 10 for a railway station as a civil engineering / building structure using the structural member 1, for example, after shaving or embankment, A conventional foamed resin block 7 having no cement hardened material layer and a structural member 1 on the upper surface and side surfaces thereof are laid on a foundation 6 which is laid with sand or gravel and subjected to tamping work from above to solidify. A hardened cement layer 3 is laid on the surface to form a stacked structure, and a floor member 8 is formed on the upper surface of the structure by asphalt, concrete, tile, or the like. Further, if necessary, a wall member 9 such as a concrete plate or a sheet pile is installed and fixed on the side surface portion by using the structural member 1 in which the jig 4 is embedded in the hardened cement layer 3. I do. 5 is a rail. In this case, it is sufficient that the wall member 9 can be fixed.
Need not be buried. Also, in this case,
The structural member 1 in which the receiving jig 4 is embedded is protruded from other structural members 1 at regular intervals to form a side surface of the structure, for example, between the fixed wall member 9 and the side surface of the structure. The heat insulating space 11 can also be formed.

[0013]

[Effects of the Invention] Since the structural members for civil engineering and construction used in the present invention are block-shaped, they are lightweight and convenient to carry. Further, since the hardened cement layer is integrated with the foamed resin block in advance, when constructing a building, for example, a platform for a railway station, by the foamed resin stacking method, the conventional method is applied to the upper surface and side surfaces of the stacked structure. In the above, since the floor slab layer which had to be constructed again has already been formed, the floor and the wall of the platform can be formed only by simple construction. Furthermore, by using a structural member in which a receiving jig is embedded in the hardened cement layer, it is possible to easily provide a wall member such as a sheet pile on a side surface portion of the platform structure, and, of course, to provide a wall member and a platform structure. A heat-insulating space that can prevent thermal deterioration of the foamed resin block between the side wall and the side wall can be easily formed.
