式断熱構造物）。◇ Conventional technology ◇ Small-sized freezers and refrigerators are constructed by assembling insulation panels (fabricated insulation structures), or inumen bond freezers and refrigerators are constructed by building frames made of steel frames, reinforced concrete, etc. It was constructed by pasting and laying insulation panels (built-in insulation structure).
そして、組立式冷凍・冷蔵庫も築造式冷凍・冷蔵庫も床
コンクリートを打設する型の断熱床はまず、基礎間に割
栗石が敷設され、その上に、ベースコンクリートが打設
される。In the case of prefabricated refrigerators and freezers, as well as built-in refrigerators and refrigerators, in the case of concrete-cast insulating floors, cracked stone is first laid between the foundations, and then base concrete is poured on top of that.

が打設されて、断熱床が構築されていた。Further, on top of the base concrete layer, a heat insulating material such as foamed urethane, phenol, or styrene board, which has a certain load capacity but has weak water permeability, is laid to form a heat insulating layer. Next, a floor concrete layer of a certain thickness is poured on the heat insulating material layer to construct a heat insulating floor.

層も完全な不透水機能を有さないため、やがて水分が床
コンクリート層及び断熱床を浸透してゆき、その水分が
冷凍庫内の冷熱により凍結されて、床コンクリート層の
凍上及び破壊を引き起していた。However, since neither the insulation layer nor the concrete floor layer has a completely water-impermeable function as described above, moisture eventually permeates through the concrete floor layer and the insulation floor, and that moisture is frozen by the cold heat in the freezer. This caused frost heaving and destruction of the concrete floor layer.

工程とコストと工期を必要としていた。◇Problems to be solved◇ However, the conventional floor structure requires the use of many expensive large-diameter PVC pipes, requires many construction steps, and requires pre-prepared through holes in the foundation. There is a need,
For this reason, constructing a frost heaving prevention insulation floor required a considerable amount of process, cost, and construction time.

トで固定し土台を設は上記４４ケ。(Patent Application No. 167-198 to 167501) Saranko The insulation panels for walls with ventilation holes used in the present invention are Type 1, which has joint frames 70 on the top and bottom, left and right sides, and Type 1, which has joint frames 70 on the top, bottom, left and right sides, and the innermost side. It is possible to use any of the following types of panels: Type 2 on the top end, Type 3 on the top, left and right sides, and Type 4 on the left and right sides and the top end of the inner surface. First, construct the foundation (underground beam) 2 at the location. Next, a split stone layer 4 is laid between the foundations 2, and a base concrete layer 10 is placed on top of the split stone layer 4. At this time, formwork such as vinyl chloride pipes, wood, square pipes, etc. is partially or completely buried from the upper surface of the base concrete layer IO, and is removed after the base concrete layer has hardened. Then, a cold air flow passage 14 was formed on the top surface of the base concrete layer, fixed with anchor bolts, and a foundation was established.

た断熱材を使用する必要がある。Next, a heat insulating material having load bearing capacity and high cold insulation properties such as expanded polystyrene, foamed phenol, foamed urethane, etc. is laid on the base concrete layer 1o to form a heat insulating material layer 18. At this time, it is necessary to use a heat insulating material in which the upper half of the cold air circulation groove is carved at a position corresponding to the cold air circulation groove provided on the insulation layer.

。It is also possible to provide only the lower part of the heat insulating layer 18 without providing the entire cold air flow passage 14 on the 1-Scottcrete I stomach, but in this case, it is not preferable in view of the cold insulation properties of the heat insulating floor.

断熱床よりも凍上の危険は少ないといえる。The insulation floor constructed by placing and laying M-cut J tunnel 22 is M-cut J tunnel 22. The flannel 22 itself has water impermeability and heat insulation properties, and the joints (floor to floor and floor to wall) also have water impermeability and heat insulation properties, so this is an insulated floor constructed by pouring floor concrete. It can be said that the risk of frost heaving is lower than that of
