Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor structure of an apartment house having a RC structure, a gymnasium, an office building, a classroom, etc., and more particularly, to a support leg capable of adjusting a level. The present invention relates to a floor structure provided with: 2. Description of the Related Art As a floor structure which is required to have a floor impact sound insulation property on a floor, a construction method called a floor placement method has been used. As shown in FIG. 10, an elastic body 3 of a support leg 2 is placed on a floor base 1 such as a concrete slab, and a predetermined gap S is formed between the panel bodies 4 to which the support leg 2 is attached. The disposing material 100 is stuck on these panel bodies 4 without gaps. Then, as shown in FIG. 11, the finishing material 101 was stuck on the piling material 100 to constitute a floor structure. In the conventional floor structure, a wood-based material, such as particle board, plywood, or a damping material sandwich panel, is often used for the panel body 4, but these materials are used under the floor. There were inconveniences such as warping due to the moisture accumulated in the space and lowering the durability. Further, regarding the sound insulation performance of the floor, when an impact force is applied to the floor panel, the elastic body 3 is deformed and tries to buffer the impact force. However, since the air layer under the floor is sealed, this is the spring resistance. As a result, the buffer effect was reduced. Accordingly, the present invention improves durability and sound insulation by rapidly releasing air in the underfloor space into the room above the floor, and corrodes a wooden panel body without keeping moisture under the floor. It is an object of the present invention to provide a floor structure that does not have any problem. SUMMARY OF THE INVENTION In order to achieve the above-mentioned object, the present invention relates to a wooden panel having a level-adjustable supporting leg having an elastic body at a lower end thereof and a floor panel such as a concrete slab. In a floor structure in which a flooring material and a finishing material are affixed on a base board at predetermined intervals and a discarding material and a finishing material are adhered, a skirting board is attached to a wall through a rim, and a gap on the back side of the skirting board is provided. Thus, the underfloor air and the indoor air are always circulated. Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. In the first embodiment shown in FIG. 1, a panel body 4 having a level-adjustable support leg 2 having an elastic body 3 at its lower end is laid at predetermined intervals on a floor base 1 such as a concrete slab. A disposing material 5 is stuck on these panel bodies 4. A finishing material 6 is provided on the waste material 5,
The finishing material 6 is made of a material having air permeability such as a tatami mat or a carpet.
A rim 7 is attached to the wall 9 and a skirting 8 is attached to the rim 7. Air under the floor is constantly circulated on the floor from the gap on the back side of the skirting 8. As shown in FIG. 2, the body edge 7 is formed with grooves extending vertically at regular intervals. This groove forms a gap on the back side of the baseboard 8.
The finishing material 6 does not necessarily need to be a material having air permeability. In a second embodiment shown in FIG. 3, a panel body 4 having a level-adjustable and supporting leg 2 having an elastic body 3 at its lower end is laid at predetermined intervals on a floor base 1 such as a concrete slab. On the panel body 4, a waste material 5 is stuck at a predetermined interval. The gap 5A formed between the waste materials 5, 5 constitutes a ventilation means. A skirting board 8 is attached to the wall 9 via a rim 7. In the third embodiment shown in FIG. 4, the pruning material 51 is stuck on the panel body 4 without any gap, and
1 were formed with holes 51A, and these holes 51A were used as ventilation means. The formation positions of the large number of holes 51A are formed at the positions of the gaps S formed by separating the panel bodies 4 from each other. FIG. 5 shows a modification of the third embodiment.
1A is formed in a different place. In these embodiments, the finishing material 6, the rim 7 and the baseboard 8 are not shown, but they are provided in the same manner as in the first embodiment. In the fourth embodiment shown in FIG. 6, an expanded metal is used as the pruning member 52. The holes of the expanded metal constitute the ventilation means. The expanded metal has a larger effective aperture ratio than that of the above-described embodiment, allows smooth air to escape, and improves ventilation performance. Tatami is preferred as the finishing material 6 provided on a material using expanded metal.
Also in this embodiment, the rim 7 and the baseboard 8 are attached to the wall 9. In the fifth embodiment shown in FIG.
The panel body 4 is set so that the interval S provided between the panel members 4 is in the longitudinal direction of the panel body 4, and the gap 5 A between the pruning members 5, 5 is set to be orthogonal to the interval S. Things. Such a configuration is suitable for a floor structure of a school classroom or the like. In this embodiment, the wall 9 is formed similarly to the first embodiment.
A baseboard 8 is attached to the side. In the sixth embodiment shown in FIG. 8, the panel body 4 is formed of a zinc-plated steel deck plate, unlike the above-described embodiments in which the panel body 4 is formed of a wood-based material. Panel body 4 consisting of this deck plate
The piling material 51 provided on the top may be the piling material 5 shown in FIG. 3 or FIG. Further, the disposing material 52 shown in FIG. 6 may be used. In the case where a deck plate is adopted as the panel body 4, the underfloor air flows through the groove portion of the deck plate and flows over the entire surface of the disposing material 51 having the hole 51A, so that more ventilation can be achieved. Further, the use of a perforated deck plate or the use of a damping steel plate can further improve the sound insulation performance. The baseboard 8 is also provided in this embodiment, but is not shown. The graph shown in FIG. 9 shows the result of sound insulation measurement when an impact is applied by a heavy floor impact source based on JIS A1418. The concrete slab is 150 mm.
, The dotted line is the conventional floor structure shown in FIGS. 10 and 11,
The solid line is the data of the embodiment of the present invention in which an effective ventilation area of 20% was secured on the floor. As is clear from this graph, the sound insulation performance was improved by 3 to 8 dB over each frequency in the case where the ventilation means was provided. Furthermore, when a smoke tube was placed under the floor and the state of ventilation was checked, smoke was clearly observed from the floor opening. L-40 and the like indicating the sound insulation grade in the graph are as follows. [Table 1] As described above, according to the present invention, a wooden panel having a level-adjustable support leg having an elastic body at its lower end is provided on a floor base such as a concrete slab at a predetermined interval. In a floor structure in which a paneling material and a finishing material are stuck on these panel bodies, a skirting board is attached to the wall via the rim, and the air under the floor and the room are connected through the gap on the back side of the skirting board. Since the configuration is such that the air is constantly circulated, it is possible to prevent moisture from being trapped under the floor, warping the floor surface, and rotting the floor panel. In addition, even if an impact is applied to the floor, the air under the floor can quickly escape to the floor, and the air under the floor acts as a spring and a resistance without reducing the buffering effect and improving the floor impact sound insulation. be able to.
