On the other hand, the mold member 11 is formed by integrally forming a flat mold portion 19 extending in the horizontal direction and supporting legs 20 provided at a plurality of places where the mold portion 19 is to be supported. It is a thing. The support leg portion 20 is formed in a cylindrical shape that protrudes downward from the mold frame portion 19, and is formed such that an outer diameter thereof gradually decreases downward. The support 16 of the form support member 10 is inserted into the support leg 20 of the form member 11, and the lower end of the form member 11 is detachably fitted to the step 18 of the pedestal 15. Thus, the form supporting member 10 is supported by the form supporting member 10 in a state of floating from the foundation floor F.

Next, a first embodiment of a method for constructing a wet floating floor according to the present invention using the floating floor formwork having the above-described configuration will be described with reference to FIGS. First, as shown in FIG. 2, the level of the floor base is determined, and after attaching the wall trimming material 21, a level thread 22 is stretched using a level ruler. Next, as shown in FIG. 3, the plurality of form support members 10 and the support columns 16 are inserted into the support legs 20 at predetermined positions on the base floor F, and the lower ends of the support members 10 are stepped portions of the pedestal portions 15. A form for a floating floor comprising the form member 11 fitted to 18 is laid over the entire surface of the base floor F, and a fibrous reinforcing material such as fiber is provided on the form member 11. I do. At this time, the mortar (elastic curable material) 23 is filled in the hole 17 of the support 16 in the form support member 10 before or after it is mounted on the base floor F, and is hardened. A nail member 24 is cast in the inside 23. And
As shown in FIG. 4, on the upper end surface 16a of the support portion 16, a top-end floating formwork 25 that defines the upper surface of the floating floor is attached using the nail member 24. Here, as shown in FIGS. 10 and 11, the top-end floating mold frame 25 is a plate-like member formed of, for example, foamed polypropylene, and has a lower surface 25a formed flat. Reinforcing ribs 26 are formed in a lattice shape on the upper surface of the top-end floating form 25, and two sides 25b of the outer periphery are engaged with two sides 25b of the adjacent top-end floating form 25. The connection reinforcing rib 25c is formed.

The top-end floating form frame 25 has a cushion member 27 made of a foam molded body adhered to a lower surface 25a thereof, and then has a hole 28 formed at the intersection of the reinforcing ribs 26 in the hole 28. The nail member 24 is attached to the upper end surface 16a of the support portion 16 by being inserted. After attaching the top-end floating form 25 to the entire surface of the section forming the floating floor in this way, as shown in FIG. 5, the mortar is injected into the injection hole 29 formed in the top-end floating form 25.

According to the floating floor form having the above structure,
Since the floating floor formwork is constituted by the formwork support member 10 and the formwork member 11 formed of foam synthetic resins different from each other, similar to the conventional one shown in FIG. By setting the mechanical strength and hardness appropriately, it is possible to construct a floating floor that meets the various requirements required for each part. In the method of constructing a wet floating floor using the
On the top 5, a support 16 is formed integrally with an upper end 16a extending to the top position of the floating floor, and a top floating formwork 25 that defines the upper surface of the floating floor is attached to the upper end of the support 16; A mortar 12 is provided between the floating floor form and the top floating form 25.
, The mortar 12 is prevented from contaminating the surroundings such as walls and floors due to scattering at the time of casting, and there is no need to level the soil or press down the surface from within the mortar 12. Therefore, the surroundings are not contaminated by workers entering and leaving the mortar. Therefore, the work for curing the surroundings and the cost required for the surroundings can be greatly reduced, and by attaching the top-end floating form frame 25 to the support 16, it is easy and uniform without skill. A remarkable effect that a floating floor with high precision can be constructed can be obtained.

In addition, since the worker does not ride on the floating floor formwork to perform the work, it is not necessary to use a high-strength wire mesh as a reinforcing material for the mortar 12, and the fiber-like reinforcement such as fiber can be used. Since the material can be used, there is no danger of damaging the room, and the installation cost can be reduced. In addition, since the floating floor form itself can be softened, it is possible to achieve both weight reduction and cost reduction.
Further, since the hole 17 is formed in the support 16 and the mortar 23 is filled in the hole 17 and hardened, the top floating frame 25 can be directly attached to the mortar 23 by nailing. Therefore, the work is easy, and a wet floating floor base that can be nailed can be constructed.

Further, the mortar 1 is provided by attaching a cushion material 27 to the lower surface of the top floating frame 25 in advance.
Since the cushioning material 27 can be integrally driven into the upper surface of the base material 2, a floating floor substrate having excellent softness and sound insulation performance can be constructed without using a costly surface finishing material with a cushioning material. The cushion material 27
Thereby, the curing of the cracks due to the surface drying of the mortar 12 can be performed at the same time. In addition, since a foam molded article is used as the cushion material 27, it is possible to prevent the occurrence of defects such as pinholes due to air accumulation on the surface when the mortar 12 is injected, and to the space of the cushion material 27. Since the mortar 12 penetrates, the mortar 12 can be driven into the upper surface of the mortar 12 without using an adhesive, so that the number of bonding steps in the surface finishing of the floating floor can be reduced, and the cost can be reduced. . In addition, since foamed polypropylene is used for the top-end floating formwork 25, the weight can be reduced to 1/3 to 1/6 as compared with the case where ordinary wood is used.
Therefore, the handling becomes extremely easy, and since there is no hygroscopicity and the peeling off from the mortar 12 is easy, there is no danger of curling and the diversion is excellent. In addition, since the cutting work can be easily performed with a blade or the like, the work is simple, and there is no danger of damaging surrounding walls and fittings due to lateral holding or swinging.
