Definitions

  • the present invention relates to a method of constructing a floor between floors by forming a floor on the ground without leaving a space under the floor, and making the floor excellent in heat insulation, moisture resistance, sound insulation and the like.
  • the construction of the floor is done by embankment as necessary, adjusting the ground height, laying the split chestnuts, and then separating the plastic film (hereinafter referred to as “film”) and the heat insulation material separately. And concrete is placed on top of it.
  • film plastic film
  • a rigid synthetic resin foam board hereinafter referred to as a “foam board”
  • the film functions as a moisture-proof layer.
  • the top surface of the split chestnut is sprinkled with some sand to smooth the surface, but if this sand is thickly covered with the split chestnut layer, the floor becomes unstable. It is inevitable that the split chestnut will abut the film and insulation on it.
  • the film and the heat insulating material are laid separately and over a wide area, when laying the heat insulating material after laying the film, the heat insulating material must be laid on the film. It cannot be obtained, and after laying the heat insulating material, the concrete must be laid on this.
  • the film and the heat insulating material are often stepped on the split chestnut, so the film may hit the corner of the split chestnut during the laying work, or the worker may break the film. There is a possibility that the desired moisture resistance may not be obtained.
  • foamed foam is used as heat insulating material, it is not only easy to crack due to work aging, but also lightweight. As a result, the rupture is scattered by the wind and is lost, which may cause a decrease in new heat property.
  • the invention aims to prevent a decrease in moisture resistance due to film breakage during construction of a soil floor and a decrease in heat insulation due to cracked and missing foam boards.
  • the above-mentioned object is achieved by laying stone on the ground, laying foam on which a film is bonded on the lower surface or both surfaces in advance, and laying a concrete thereon. .
  • the film for imparting moisture-proof property to the slab to be constructed and the foam, which is a newly matured material, are joined in advance, both are laid at the same time. Therefore, the workability is better than the conventional method of laying the film and laying the foam board separately. Also, since the film and foam can be laid directly on the film without the need for workers, and because the film is pre-bonded and integrated with the foam board, it is less likely to break during construction. It is unlikely that the film becomes damaged due to film damage.
  • the foam board is reinforced, and even if an operator rides on the foam board at the time of placing concrete, the foam board is not damaged. It is difficult to crack. Also, even if the foam board breaks, the broken part is held by the film and is not blown away by the wind, so there is no significant drop in heat insulation due to the missing part.
  • the moisture-proof structure is made up of the upper and lower films, which provides a synergistically high moisture-proof effect, and foams between both films.
  • the reinforcement of the foam board can be enhanced.
  • FIG. 1 is constructed using foam ⁇ 4 with film 3 joined to the lower surface in advance.
  • FIG. 2 is a longitudinal sectional view showing a part of the soil floor, which is constructed by using a foam plate 4 in which films 3a and 3b are previously joined to both sides
  • FIG. Fig. 3 is an explanatory view of laying a foam board 4 to which a film 3 has been previously bonded to the lower surface.

  • the height of the ground 1 inside the foundation is adjusted by embankment as necessary. It is preferable to provide a heat insulating material 7 on the outer surface of the foundation 6 in order to prevent heat from escaping from the side.
  • the heat insulating material 7 may be made of the same material as the foam plate 4 described later, or may be made of another material.
  • the stone 2 is laid on the ground 1 inside the foundation 6.

  • the thickness of the layer of the stone 2 may be appropriately determined according to the hardness of the ground 1 and the like. Further, it is preferable that sand 8 is spread on the surface of the stone 2 so as to fill the gap between the stones 2 and the upper surface thereof is made substantially flat. By doing so, the film 3 or the foam plate 4 with the films 3a and 3b to be laid next can be easily installed horizontally, and the floor can be easily made horizontal.
