Definitions

  • the present invention relates to a floor structure arranged on a slab of a building such as a multiple dwelling house, and a floor base panel used for the floor structure.
  • a dry type sound shielding double floor is used as the floor structure of the building of the multiple dwelling houses such as an apartment house.
  • Conventional dry type sound shielding double floor is structured in such a manner that a vibration-proof support leg is arranged on the slab which is a concrete floor, at a predetermined interval, each edge of the floor base panel constituted by a particle board or plywood is adhered and fixed on the support board of the vibration-proof support leg, and the finishing lining such as the flooring is conducted on the floor base panel.
  • the sound shielding is not enough although the finishing lining is conducted on the floor base panel.
  • the rubber mat is laid between the floor base panel and the finishing lining so that a countermeasure of the sound proof is conducted.
  • the interval of the vibration proof support leg is increased, it is considered that the strength is increased by increasing the thickness of the floor base panel, however, because the weight of the floor base panel is increased by the amount, a problem that conveying cost is increased, and the conveyance at the time of operation becomes troublesome, or a problem that it is not suited for the application to the floor of the very high building dwelling house, is generated.
  • the present invention is attained, and the object of the present invention is to provide a floor structure which is light weight, and by which the floor impulsive sound level can be reduced, and a floor base panel used for the floor structure.
  • the invention is characterized by having the following arrangement.
  • Fig. 1 is a view showing the sound shield floor of the dry type sound shield double floor according to the first embodiment of the present invention.
  • This sound shield floor 10 includes a vibration proof support leg 30 arranged with a space on a slab 20 which is a body of the building, hollow base panel 40 supported by the vibration proof support leg 30, and finishing material 50 placed on the hollow base panel 40.
  • the finishing material 50 is flooring material, tatami, and carpet, and an adhesive material may also be arranged between the finishing material 50 and the hollow base panel 40 at need.
  • the vibration proof support leg 30 is constituted by a support bolt 32 rotatably supported by a cone frustum vibration proof rubber 31, and a support board 33 screwed on the support bolt 32.
  • a hexagonal hole 34 is formed, and as shown in Fig. 1, the hollow base panel 40 is structured so as to be placed on the support board 33 with a space so that the hexagonal hole 34 can be looked from the upside.
  • the height of the hollow base panel 40 can be adjusted (leveled) by rotating the support bolt through the hexagonal hole 34 by using by using a hexagonal wrench.
  • the hollow base panel 40 may be adhered and fixed on the support board 33, or it may be fixed on the support board 33 by using a screw or bolt.
  • the hollow base panel 40 is a wood thin strip laminated plate in which a wood thin strip is laminated, and is the floor base panel structured so that substantially trapezoidal cavities 41 are formed with a predetermined interval in the longitudinal direction (floor surface parallel direction), and the strength and weight reduction can stand together.
  • Fig. 3 is a view showing an enlarged view of the side surface of the hollow base panel 40.
  • the hollow base panel 40 is so structured that the lamination direction of the wood thin strips between the cavities 41 are respectively at the about 60° obliqueness and 120° obliqueness (an area shown by signs ⁇ , ⁇ ). Therefore, in the hollow base panel 40, because the force applied in the perpendicular direction to the floor surface (Y direction) , and in the parallel direction to the floor surface (X direction) acts in almost compression direction to the longitudinal direction of the wood thin strip, the strength to the force applied from these directions becomes high.
  • the lamination direction of the wood thin strip between the cavity 41 and the cavity 41 is alternately laminated in the left and right symmetrical inclination angle to the perpendicular direction to the floor surface, the strength against the force applied from any direction of the left and right direction of the parallel direction to the floor surface is maintained uniformlyhigh. Accordingly, although the weight is reduced by providing the hollow structure to the hollow base panel 40, the strength (rigidity) in the perpendicular direction to the floor surface and in the parallel direction to the floor surface can be maintained high. Thereby, because this hollow base panel 40 can increase the strength/weight ratio as compared with the particle board or lamination plate generally used as the floor base panel, even when the strength equal to the conventional floor base panel is provided, the panel weight can be reduced.
  • the hollow base panel 40 is formed, as shown in Fig. 1, such that, in the area on the support board 33 of the vibration proof support leg 30, the cavity 41 does not exist.
  • the perpendicular area to the floor surface on the support board 33 of the hollow base panel 40 is formed solid.
  • the vibration energy propagated from the impact point of the hollow base panel 40 is repeatedly reflected before it is transmitted to the support board 33, when it repeatedly passes the complicated transmission path of the hollow portion, it is attenuated in a short time.
  • the vibration energy transmitted from the hollow base panel 40 to the slab 20 through the vibration proof support leg 30, or the sound energy transmitted by the vibration of the hollow base panel 40 to the slab 20 can be reduced, and the sound shielding floor 10 can greatly reduce the floor impact sound level.
  • the panel dimension can be made larger than the conventional one. Accordingly, when the dimension of the length and width of the hollow base panel 40 per one sheet is increased, the arrangement interval of the vibration proof support leg 30 can be increased, and the number of use of the vibration proof support leg 30 can be reduced. When the number of use of the vibration proof support leg 30 can be reduced, because the height adjustment (horizontal leveling) operation of the hollow base panel 40 is simplified, the material cost and the operation cost can be reduced.
  • the resonance frequency of the floor base panel is near the resonance frequency of the slab 20, and the sound shielding property is reduced.
  • this hollow base panel 40 because not only the dimension of the length or width of the hollow base panel 40, but the degree of freedom of the design work of the thickness dimension is increased, the shape can be easily designed so that the resonance frequency of the base floor panel is separated from the resonance frequency of the slab 20.
  • the sound shielding floor 10 having a predetermined rigidity and sound shielding property can be easily designed.
  • the resonance frequency of the hollow base panel 40 can be changed.
  • This hollow base panel 40 is produced as follows. As shown in Fig. 4, after the binder is adhered to the wood thin strip, a core 55 constituted by the trapezoidal aluminum bar connected at the equal interval by a connection plate 55a is arranged on the first layer - several layers (a plurality of layers) of the wood thin strip, and after the amount of one layer - several layers of the wood thin strip is applied thereon, the core 55 constituted by the trapezoidal aluminum bar connected at the equal interval by a connection plate 55b is arranged thereon, and the wood thin strips is further applied. In this case, the core 55 connected by the connection plate 55a and the core 55 connected by the connection plate 55b are arranged so that the trapezoid is reversed upwardly and downwardly.
  • the laminated body 70 in which the wood thin strip are laminated is thermal pressure molded at the temperature 140 - 220 °C, pressure 15 - 40 kg/cm, for 6 - 15 minutes, and thermal pressure molded until the thickness is 1/3 - 1/30, and after the core 55 is pulled out after the cooling, by trimming the outer periphery of the laminated body 70, the hollow base panel 40 can be produced.
  • the wood thin strip normally, an akamatsu (Japanese red pine), karamatsu(Japanese larch), ezomatsu(Saghalin spruce), todomatsu (Soghalin fir), aspen, and lodge pole pine are used, and the kind of wood is particularly not limited.
  • the wood thin strip may be arranged in such a manner that the grain of wood is arranged in almost one direction, or the wood thin strip may be laminated in such a manner that it is made three layer structure, and the direction of grain of wood of the adjoining layers is perpendicular to each other, however, particularly it is not limited.
  • a plurality of kinds of wood thin strips may be mixed, or the mixing rate of the wood thin strip and the binder may be changed in response to Corresponding to the strength or rigidity of the hollow base panel 40 which is a target.
  • any one of the foaming binder resin, no-forming binder resin, and their mixture, may be used.
  • the foaming binder resin is preferable. Because the foaming binder resin combines the wood thin strips with each other, and the resin itself foams, the amount of use of the resin is reduced by spreading the gap of the wood thin strips by the foaming cell, and the density of the hollow base panel 40 can be reduced. Further, the heat insulation effect or sound shielding effect of the hollow base panel 40 can be increased by the foaming cell.
  • the foaming binder resin either one of the self-foaming foaming resin, or mixing foaming resin in which the foaming agent is added to the non-foaming resin such as phenol, urea, epoxy, or acrylic resin, may be used.
  • the self-foaming foaming resin the foaming polyurethane resin, isocyanate resin, or preferably PMDI (poly -metallic MDI or coarse MDI) can be listed.
  • an amount of the binder to the wood thin strip is 3.5 - 20 weight parts to the wood thin strip 100 weight parts (absolute dry weight).
  • the density and strength of the hollow base panel 40 can also be changed.
  • the hardener, curing catalyst, hardening accelerator, diluent, thickener, dispersing agent, or water repellant agent may be added to the binder as the need arise.
  • the wood thin strip is previously acetylated.
  • Fig. 5 is a view showing a sound shielding floor of a dry type sound shielding double floor according to the second embodiment of the present invention. Because this sound shielding floor 100 is the same as the sound shielding floor 10 according to the first embodiment except a point that a weight 60 is arranged between the hollow base panel 40 and the finish material 50, the same sign is attached to the same portion, and the duplicated explanation is omitted, and only the different portion will be described below.
  • Fig. 6 is a view showing the arrangement position of the weight 60 arranged on the hollow base panel 40.
  • the weight 60 is arranged on the upper surface of the hollow base panel 40 in such a manner that it is arranged on the upper side position of the support board 33 of the 6 sets of vibration proof support legs 30 supporting the hollow base panel 40. That is, although the hollow base panel 40 is vibrated in the arrowed direction as shown in Fig. 7 when the impact is received, the deflection or vibration speed (vibration frequency) at the time of the vibration is reduced by arranging the weight 60 as shown in Fig. 8, and the exciting force of the slab 20 can be reduced.
  • Fig. 9 As the simulation result of a case where the weight 60 is not arranged, and it is arranged, is shown, in the case where the impact is applied on the center of the hollow base panel 40, when the weight 60 is not arranged, the exciting force of the maximum about 1.0 kgf is generated, and particularly, at 57 Hz close to the resonance frequency of the slab 20, the exciting force of about 0.5 kgf is generated largely.
  • the maximum exciting force is reduced to a half, that is, about 0.5 kgf, and because the exciting force at not smaller than 40 Hz is reduced to not larger than 0.2 kgf, it can be confirmed that the exciting force at the resonance frequency of the slab 20 is greatly reduced.
  • the vibration (vibration mode) in which, when one side of the hollow base panel 40 on one support board 33 is deflected upwardly, the other side is deflected downwardly, is generated, when the weight 60 is not arranged, the vibration proof support leg 30 is swung, and the vibration is transmitted to the slab 20, however, by arranging the weight 60, because the vibration of the hollow base panel 40 can be suppressed, the effect that the stability of the vibration proof support leg 30 is increased, and the vibration proof function can be sufficiently functioned, can also be obtained.
  • the sound shielding floor 100 according to the present invention can greatly reduce the exciting force of the slab 20, in addition to the effect of the first embodiment, the floor impact sound level can be further reduced.
  • the weight 60 is formed into a rectangular parallelopiped shape, is shown in a view, however, it is needless to say that it may be an arbitrary shape.
  • the present invention can be applied to various modes, not limiting to the above-described embodiments.
  • the following modified embodiment can be carried out.

  • the vibration on the support board 33 of the hollow base panel 40 is suppressed, or the swing of the vibration proof support leg 30 accompanied by the vibration of the hollow base panel 40 is reduced, and the exciting force of the slab 20 can be reduced by the method in which the weight is arranged between the hollow base panel 40 and the support board 33 as shown in Fig. 13, or by the method in which the end portion of the hollow base panel 40 is covered by the weight 60 as shown in Fig. 14, or by the method in which the weight 60 is inserted in the predetermined area on the support board 33 of the hollow base panel 40 as shown in Fig. 15.
  • the weight 60 is attached to the support board 33 itself and by increasing the moment of inertia of the vibration proof support leg, a case where the vibration proof support leg 30 is swung by the vibration of the hollow base panel 40 can be avoided.
  • the case where the hollow base panel 40 described in the first embodiment is used is described, however, when the desired floor impact sound level can be obtained by only arranging the weight 60, the conventional floor base panel such as the particle board can be used.

In this case, it is preferable that they are superimposed so that the extending direction of the cavity 41 of each hollow base panel 40 is different. When the extending direction of the cavity 41 is made different, it is for the reason in which, because the propagation speed of the vibration to the same direction is different for each hollow base panel 40, by the shift of the vibration of the mutual hollow base panels 40, the vibration energy can be attenuated.
