Description

[Detailed explanation of the idea]

This invention relates to floor structure, especially sound absorption, sound insulation effect,
and a floor structure with excellent vibration-proofing effects. Conventionally, when floors are made of plywood, the plywood itself has poor sound absorption and insulation effects, so noise from upstairs,
In particular, there was almost no protection against the impact sounds of dropped objects, children's voices, vibrations, etc. echoing downstairs. Therefore, in the past, measures have been taken to absorb some of the impact noise by creating a structure that cushions and supports floor joists, joists, etc., but this has not been able to achieve a sufficient effect. In view of this, the present invention was developed with the aim of providing a floor structure that not only has excellent sound absorption and insulation effects, but also has a cushioning effect.
A structure in which the upper plate floats relative to the lower plate by interposing aggregate made of elastic material between the lower plate that is directly or indirectly fixed to the floor joist side and the upper plate that makes up the upper surface of the floor. At the same time, the side edges are separated from the wall components by intervening seismic insulation materials to achieve the above objective. Hereinafter, the present invention will be described with reference to embodiments shown in the drawings. As shown in FIG. 1, a board 1 used as a floor board is made up of an upper board 2 and a lower board 3 that constitute the upper and lower surfaces of the board 1, and an elastic aggregate 4 interposed between these upper and lower boards 2 and 3. The upper plate 2 and the lower plate 3 have
Wooden boards, plywood plywood, various boards, metal plates, and other appropriate materials are used. The elastic aggregate 4 is made of natural rubber, synthetic rubber, or other similar elastic material that can be bonded, and as shown in FIG. flat surface for adhesion 5,

The beam portions 6, 6... are connected to the adhesive flat surfaces 5, 5.
These beam parts 6,
Long fibers 7 having a hair length of approximately 1 to 3 m/m are flocked as densely as possible on both sides of the adhesive 6 and on the back surfaces of the adhesive flat surfaces 5, 5, etc., by electrostatic flocking or the like. The plate material 1 is constructed by adhering and interposing the adhesive flat surfaces 5, 5, . On the longitudinal side end face of the upper plate 2, a protrusion 8 is formed on one side and a grooved line 9 is formed on the other side, and when the plate material 1 is laid down, the protrusion 8 and the grooved line 9 fit together. The so-called "honzane process" is applied to join the parts by mating. The plate material 1 constructed in this way has a length of 1800 m/
m, width 900m/m, or length 1800m/m, width
It is formed to standard dimensions such as 300m/m. As shown in FIG. 8, the vibration-proof edge material 10 is made of natural,
It is made of an elastic material such as synthetic rubber and has a substantially U-shaped cross section, and has a vertical surface portion 10a,
The vertical surface portion 10a has an upper edge portion 10b extending at right angles to one side of the upper end of the vertical surface portion 10a, and a lower edge portion 10c extending parallel to the upper edge portion 10b at the lower end of the vertical surface portion 10a. is shorter than the upper edge 10b,
The upper edge 10b has a height dimension such that when the end surface of the lower edge 10c is brought into contact with the end surface of the lower plate 3 of the plate material 1, the upper edge 10b is placed on the upper surface of the upper plate 2 (see FIG. 3). Next, an example of building a floor structure will be explained. Figure 1 shows an example of the flooring structure of a general wooden house.A board 1 is laid on the joists 12, 12, which are arranged and fixed at predetermined intervals on the main drawer 11, and below the board 1. Connect the end of board 3 to joist 1 as shown in Figure 2.
2 with nails 13. Note that the lower plate 3 may be fixed by adhesion in addition to nailing. Even if the lower plate 3 of the plate material 1 is fixed to the joists 12 as described above, the upper plate 2 is supported in a floating manner by the elastic aggregate 4, and the ridges 8 of the upper plate 2 and the recesses are formed on the joists 12, 12... The floating support of the upper plate 2 does not change even if the strips 9 are sequentially fitted and laid down. In the case of the above embodiment, it is desirable that the arrangement interval of the joists 12, 12, . . . be 300 m/m or less in order to prevent resonance. At the end of the floor, as shown in FIG. 3, the seismic edging material 10 is placed along the side edge of the board 1, its lower edge 10c is placed on the joist 12, and the end surface of the lower edge 10c is placed along the side edge of the board 1. The upper edge 10b of the board 1 is placed along the upper surface of the upper board 2 of the board 1, and fixed to the upper board 2 with nails 14 or adhesive.
A baseboard 15 constituting the wall portion is constructed so as to be placed on top of this upper edge 10b. The surface of the upper plate 2 of the plate material 1 stretched as described above is used as a cloth finish by oil stain coating, laying of carpets, etc., flooring, and rough flooring of tatami mats. FIG. 4 shows an example of a modified construction when laying the floor. An underlay plywood 16 is fixed on the joists 12, 12, etc. by nailing, etc., and the lower board 3 of the board 1 is placed on top of the underlay plywood 16. This is a case where it is covered with adhesive. According to this embodiment, the board material 1 is covered with plywood 16
Since it is stretched upward, the thickness of the lower plate 3 is substantially increased, and sufficient strength can be obtained even when the joist spacing is wide, making it suitable for renovation work. Moreover, it can be installed using only adhesive. FIGS. 5A and 5B show still another modified construction example, in which the building is made of concrete and the floor is laid on a concrete frame 17. To lay a floor on such a concrete frame 17, as shown in FIG. It is fixed by embedding it in a layer of mortar 19 cast on top of the mortar 17. In the above case, the thickness of the mortar 19 is 40 to 50
m/m, the height of the anchor member 18 is 30 m/m.
m, and the lower end of the anchor member 18 is made not to contact the concrete frame 17. Further, as shown in FIG. 5B, leg members 18', 18', . A grounding body 18'' made of material is attached, and the grounding body 1 of the leg members 18', 18'...
8'', 18''... may be grounded on the concrete frame 17 and the plate material 1 may be stretched. In this case, the tensioning work can be further facilitated by making the leg member 18' or the grounding body 18'' adjustable in the height direction with screws or the like. In the case of Fig. 5, the seismic edging material 10 is used in the same manner. Several representative construction examples have been described above.
In either case, the upper plate 2 of the plate material 1 constituting the floor is elastically supported in a floating manner via an elastic aggregate 4 with respect to the lower plate 3 which is fixed to the floor structural material, that is, the joist 12, the concrete frame 17, etc. Since the side ends are also insulated by the seismic edging material 10, the impact applied to the upper plate 2 is absorbed by the elastic aggregate 4 made of elastic material and the seismic edging material 10, and the impact is absorbed by the lower plate 3 and, by extension, the floor. This prevents the impact from being directly transmitted to the structural material, effectively blocking the impact. In addition, sound waves such as impact sounds and noises applied to the upper plate 2 are attenuated while being propagated to the upper adhesive flat surface 5 of the elastic aggregate 4, the beam portion 6, and the lower adhesive flat surface 5. The reflected waves are absorbed by the fiber material 7, which exhibits sound absorption and sound insulation effects, resulting in a high sound insulation effect. Furthermore, the compressive strength of the elastic aggregate 4 is reduced by applying flocking to the other surfaces of the elastic aggregate 4 except for the flat surface 5 for adhesion, in order to prevent heavy objects from being placed on the board 1 or from impact. As shown in the table, it has increased significantly.

[Table] In the table above, single lamination refers to the case where one piece of elastic aggregate 4 is used, and double lamination refers to the case where 2 pieces of elastic aggregate are used.
This is the case when they are used in stacks. As described above, by flocking the elastic aggregate 4, it has a compressive strength approximately twice as high as that without flocking, and it is possible to provide strong cushioning properties without increasing the hardness of the elastic material. Therefore, there is no problem that elasticity decreases when the hardness is increased, and a strong and elastic floor structure can be obtained. In addition, the elastic aggregate 4 interposed between the upper and lower plates 2 and 3 of the plate material 1 is a single piece as in the above embodiment;
This elastic aggregate 4 is stacked in two stages as schematically shown in FIGS. 9 and 10, and the direction of the beam part 6 is
By making them the same as shown in the figure, or by making them intersect as shown in FIG. 10 and bonding them using mutual adhesive flat surfaces 5, strength, sound absorption, and sound insulation effects can be further enhanced. As explained above, the present invention provides a flat surface that serves as an adhesive surface between a lower plate that is fixed to a floor structure material such as a joist or concrete frame and an upper plate that constitutes the floor surface, and a flat surface that serves as an adhesive surface. An elastic aggregate made of natural, synthetic rubber, or similar elastic material with a zigzag cross section in which trapezoids are alternately continuous with the beams connecting the joints, and with fibrous material flocked on the other surfaces except the flat surface, is interposed and bonded. to create a floating support structure for the upper plate relative to the lower plate,
Furthermore, the plates are fitted and connected by protrusions and grooves, and the side ends of the plates are connected to the floor structure material and wall material through seismic insulation material made of the same elastic material as above and having a U-shaped cross section. Due to its structure, it has excellent sound absorption and sound insulation effects, excellent cushioning properties, and no deformation such as warping. Therefore, when applied to floors above, the transmission of shock, noise, and vibration to downstairs is significantly reduced. It has various effects that cannot be obtained with conventional floor structures.
