BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a railway station platform, and more particularly, it is possible to construct the surface layer of a building very easily or without the need to construct it. The present invention relates to a railway station platform that does not cause any deviation in force.

2. Description of the Related Art Conventionally, in the construction or repair work of a building such as a platform for a railway station, an existing facility is destroyed by securing a narrow area in a limited area under heavy traffic of people and vehicles. After that, embankment and rebar were assembled to construct a new structure mainly composed of concrete. Therefore, in construction under such circumstances, large-sized transport equipment cannot be used,
Therefore, the work of transporting crushed material such as earth and sand or concrete in the repaired portion, or the transporting of materials such as a concrete hardening formwork must rely on human power. In addition, the conventional construction method using concrete requires several days to obtain the concrete of the required strength, so the construction period is long, 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 have proposed a method of stacking and executing a foamed resin block instead of embankment or concrete driving ( Japanese Utility Model Laid-Open No. 4-33714 ).

[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.On the upper surface, for the transport of heavy objects and frequent movement of people, a floor layer layer made of hardened cement and a surface layer such as asphalt are formed on it. Also, in order to increase the strength of the train against foreign matter such as heat and gravel of the train, a wall member such as a concrete plate or a sheet pile must be installed, which is troublesome.
Therefore, some of the present inventors have found a construction member in which a foamed resin block and a cement hardened material layer are integrated ( actually,
Japanese Unexamined Patent Publication No. Hei 4-119512 ). However, when a foamed resin block stacking structure is constructed using the building members on the upper surface and side surfaces, when a force is applied from the side due to an earthquake or the like,
Since the foamed resin blocks were not fixed to each other, there was a problem that displacement occurred. The present invention has also solved the above-mentioned problems in the above-described foamed resin block stacking method, and therefore, the present invention provides a very simple method of forming a surface layer material on the top and side portions of the foamed resin block stacked structure. It is an object of the present invention to provide a railway station platform which can be constructed or need not be constructed, and does not shift even when a force is applied from the side due to an earthquake or the like.

[0004]

As a result of diligent studies, the present inventors have achieved the above object by adopting the following configuration. That is, the present invention provides a railway station platform construction member in which a cement hardened material layer is laminated on at least one surface of a foamed resin block, and a hole is provided through the cement hardened material layer and the foamed resin block.

A railway station platform characterized by:

Hereinafter, the present invention will be described in more detail with reference to the drawings. In one embodiment, it is used in the present invention
As shown in FIG. 1, the construction member 1 for a railway station platform has a cement hardened material layer 3 provided on at least one surface of a foamed resin block 2 and penetrates the cement hardened material layer 3 and the foamed resin block 2. The hole 4 is provided. This hole 4 is used to insert a suitable connecting means so as to allow the platform to withstand a laterally applied force when the railway station platform is constructed using the construction member 1, and to fix the construction member. Things. The shape of the hole 4 penetrating the cement hardened material layer 3 and the foamed resin block 2 is not particularly limited, but is usually a circular shape, and the two are linearly penetrated.
The size of the hole 4 penetrating the cement hardened material layer 3 and the foamed resin block 2 may be any size as long as the connecting means can penetrate it, and usually has a diameter of 5 to 100 mm.
The hole 4 can be provided at one or more locations at any location.
For example, each of the height direction and the lateral direction of the
/ 2 places (FIG. 1), and two places where the height direction is 1/2 and the horizontal direction is 1/4. Here, the height direction and the lateral direction of the foamed resin block 2 mean the height and the lateral direction of the railway station platform when the railway station platform is constructed using the construction member 1, respectively. The hardened cement layer 3 is also installed on the upper surface of the foamed resin block 2 when the building member 1 is installed on the upper part of the platform structure, as shown in FIG. Become. The cured material layer 3 on this upper surface
Needless to say, it is not necessary to provide holes. 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.

[0006] A foamed resin block 2 constituting the construction member 1
Can be formed by various foamed resins,
Examples thereof include foamed resins such as polystyrene, polyethylene, polypropylene, polyurethane, and polyvinyl chloride. Generally, the foamed resin block 2 preferably has a density of 0.01 to 0.05 g / cm3. The size is not particularly limited, but is, for example, 100 to 200 cm long and 5 cm wide.
The thickness is preferably 0 to 100 cm and the thickness is 50 to 100 cm. 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 construction member 1
Can be formed of various cements such as concrete and mortar, and as the hydraulic cement, for example, ordinary Portland cement, moderate heat Portland cement, early strength Portland cement, low sulfate Portland cement, Portland cement such as white Portland cement, hydraulic lime, Roman cement, natural cement, alumina cement, blast furnace cement, silica cement, expanded cement, colored cement and the like. Among these, it is preferable to use Portland cement, hydraulic lime, natural cement, blast furnace cement, expanded cement, and colored cement. Also, various aggregates, reinforcing materials, lightening materials, water glass, and the like can be added to the cement. Examples of the aggregate include ordinary aggregates such as silica sand and silica foam, and artificial lightweight aggregates such as expanded clay, perlite, and expanded slag. Also, as a reinforcing material,
Various organic and inorganic fibers, such as slag fiber, carbon fiber,
There are nylon and polyester fibers. Further, as the lightening material, a density of 0.008 to 0.1 g / c of a resin such as a polystyrene resin, a polyvinyl chloride resin, or a polypropylene resin is used.
m3, foamed particles having 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 asphalt as a surface material is constructed when constructing a railway station platform, the hardened cementitious material is used. The foamed resin particles present on the surface of the layer are melted by the heated asphalt, and as a result, asphalt enters the holes of the particles after melting,
The adhesiveness between the asphalt and the hardened cement layer becomes excellent. The mixing ratio of the expanded resin particles is as follows:
It is usually 0.2 to 30 parts by weight with respect to 00 parts by weight.
The thickness of the cement hardened material layer 3 is usually 2 to 15 cm.

In order to manufacture the structural member 1, the foamed resin block 2 is placed in a mold, and an uncured cement mortar is poured into the mold so as to have a desired shape.
Cured and cured to form a hardened cement layer 3, and conversely, cured and hardened the foamed resin block 2 from the cement mortar placed in a predetermined amount in a mold frame to cure the hardened cement layer 3. A hole 4 may be formed and penetrated through the cement hardened material layer 3 and the foamed resin block 2 by a known technique. The hole 4 may be provided at the time of manufacturing the construction member 1 as described above, or a composite block having no hole may be manufactured, and the hole may be provided at a construction site by a nichrome wire cutter or the like.

Further, the foamed resin block 2 and the cement hardened material layer 3 can be separately manufactured, and the two can be integrated using an adhesive. If the cement hardened material layer 3 is integrated with the foamed resin block 2 by, for example, a reverse taper type joining means as shown in FIG.
Is preferable because it does not peel off. 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 cement hardened material layer 3 located on the side surface of the platform , as shown in FIG. The train station platform construction member 1 in which the receiving member 5 for fixing the wall member is embedded in the layer 3 may be used. The size and shape of the receiving jig 5 can be freely selected by a fixing jig for the 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.

As shown in FIGS. 4 and 5, when the railway station platform 11 is constructed using the construction member 1, after shaving or embankment, sand or gravel is laid and compacted from above. The conventional foamed resin block 7 having no cement hardened material layer is stacked on the foundation 6 hardened by performing the operation, the building member 1 is provided on the side surface, and the cement hardened material layer 3 is provided on the surface.
Lay them side by side so that they are positioned. Next,
The floor member 8 is formed on the upper surface of the platform 11 by asphalt, concrete, tile, or the like. The conventional foamed resin block 7 is preferably provided with a hole so that the connecting means can pass through the building member 1 and the conventional foamed resin block 7. If the foamed resin block constituting the uppermost surface is provided with a cement hardened material layer on the upper surface, the subsequent work can be simplified. The fixing of the construction member 1 and the conventional foamed resin block 7 is performed by applying the connecting means 9 to the through hole 4. Such connecting means 9
The present invention is not particularly limited, and examples thereof include a metal connecting rod such as iron and a wire. When a connecting rod is used, its thickness is determined by the size of the hole provided, but usually a diameter of 5 to 100 mm can be used. Preferably, both or one end of the connecting rod is threaded so that it can be stopped with a fastener 10 such as a nut. When the connecting rod 9 is fixed with the stopper 10,
Even if this stopper 10 comes out of the hardened cement layer,
It doesn't have to be out. In the case where the stopper 10 comes out of the hardened cement layer and becomes an obstacle, the periphery of the stopper may be covered with a rubber plate, a urethane plate, a plastic plate, or the like. If the building elements 1 are arranged on both sides of the platform 11, the connecting means 9 are fixed between the cement hardened material layers 3 of both building elements 1. However, when the building member 1 constitutes one side and another structure such as a wall of a station building is provided on the other side, the connecting means 9 tightens the wall and the cement hardened material layer 3. I do. Further, if necessary, a cement hardened material layer 3 may be provided on the side surface of the platform.
Using the construction member 1 in which the receiving jig 5 is embedded
Install and fix wall members such as concrete boards and sheet piles. In this case, it is only necessary that the wall member can be fixed, and it is not necessary that all of the laid construction members 1 have the receiving jig 5 embedded therein. When the wall member is installed, the building member 1 does not need to be provided on the entire side surface of the platform. Furthermore, the construction member 1 in which the receiving jig 5 is embedded
Can be protruded from other construction members 1 at regular intervals to form a side surface of the structure, or the like, to form a heat insulating space between the fixed wall member and the side surface of the structure. Note that 12
Is a rail.

[0012]

[Effect of the Invention] Since the construction member for the railway station platform used in the present invention has a block shape, it is lightweight and convenient to carry. In addition, since the hardened cement layer is integrated with the foamed resin block in advance, when constructing a railway station platform, it is necessary to reconstruct the top and side surfaces of the stacked structure in the conventional method. Since the floor layer and the wall portion which have been formed are already formed, the floor portion and the wall portion of the platform can be formed only by simple construction. Furthermore, by using a building member in which a receiving jig is buried in the hardened cement layer, it is possible to easily provide a wall member such as a sheet pile on the side surface of the platform. A heat insulating space that can prevent thermal deterioration of the foamed resin block can be easily formed therebetween. In addition, it used in the present invention
Since the building members used are provided with holes that penetrate the cement hardened material layer and the foamed resin block, the railway station platform constructed using this is constructed such that each of the building members is connected by a connecting means such as a metal rod. Since it is firmly fixed, the building member does not shift even if a force is applied from the side due to an earthquake or the like.
