Detailed description of the invention
Below, with reference to accompanying drawing, embodiments of the present invention are described.In addition, following embodiment is the example that the present invention is specialized, the technical scope be not intended to limit the present invention.
< the 1st embodiment >
With reference to Fig. 1 and Fig. 2, the flooring structure 1 involved by the 1st embodiment possess many joists 2 (shown in figure two joists 2), the multiple anti-vibration members 3 be arranged on joist 2, multiple floor plates 4 be arranged at from the top of anti-vibration member 3 joist 2, with the connecting member 5 (thickness 5mm) be arranged at across the mode of each floor plate 4 on this each floor plate 4 and the floor member 6 be arranged on connecting member 5.Wherein, floor member 6 comprises floor base material (such as, shaving board: thickness 15mm) and is arranged at the Floor Covering material (such as, earth material: thickness 13.5mm) on floor base material, in figure, floor member 6 is shown as parts.
Each joist 2 is configured to be parallel to each other.Below, if the direction that each joist 2 extends is longitudinally, be laterally with longitudinally orthogonal direction.
Floor plate 4 is extruding cement boards, and it in roughly rectangular flat shape, and has the gauge of 97mm.Floor plate 4 with make its long side direction towards the state of transverse direction across two joists 2 between.In this case, multiple floor plates 4 are to be arranged on each joist 4 along the state that horizontal plane longitudinally and is laterally adjoining each other.
Anti-vibration member 3 to correspond to the relative movement of floor plate 4 pairs of joists 2 and the parts of elastic deformation, such as, be made up of polyurethane.Overlook and see, anti-vibration member 3 is configured in four corners of each floor plate 4.By the elastic deformation of this anti-vibration member 3, vibration can be suppressed to be delivered to joist 2 from floor plate 4.
Connecting member 5 is configured to the whole upper surface covering multiple floor plates 4, is connected by each floor plate 4.In addition, as shown in Figure 3, connecting member 5 possesses the cover plate 5a covering multiple floor plates 4 from top and the vibration-damped component 5b be arranged between cover plate 5a and each floor plate 4.
Cover plate 5a is made up of the galvanized steel plain sheet of thickness 4.5mm.
When the soffit of cover plate 5a and the upper surface of each floor plate 4 are to during along the direction relative displacement on each surface, there is shear strain in vibration-damped component 5b, thus absorbs the energy of described relative displacement.Specifically, vibration-damped component 5b is made up of the chlorinated polyethylene resin with tack, by cover plate 5a and the bonding laminating of each floor plate 4.
Like this, connecting member 5 links multiple floor plates 4 across vibration-damped component 5b by cover plate 5a, thus limits the relative displacement of each floor plate 4 to each joist 2.Specifically, because multiple floor plates 4 are interconnected by connecting member 5, therefore when a floor plate 4 will rotate or reverse, vibration-damped component 5b produces shear strain between this floor plate 4 and cover plate 5a, thus can suppress (decay) described rotation or torsion.
Below, with reference to Fig. 4, the effect of described flooring structure 1 is described.
Represent with the curve shown in chain double-dashed line in Fig. 4, do not link the characteristic of the intrinsic vibration of the flooring structure involved by comparative example of each floor plate 4 (described connecting member 5 is not set).According to this characteristic, because each floor plate 4 can vibrate respectively, vibrating body (each floor plate 4) lightweight, so it is higher to make amplitude become the frequency f 1 of peak value P1.Therefore, the performance of the regarding weight level floor impact sound judged according to the amplitude of the frequency band f3 at 63Hz is not good.
In addition, represent with the curve shown in a pecked line in Fig. 4, only link each floor plate 4 and the characteristic of the intrinsic vibration of the flooring structure involved by comparative example of vibration-damped component 5b is not set.According to this characteristic, because each floor plate 4 is integrated, the heavier-weight of vibrating body (union body of each floor plate 4), so as shown in arrow Y1, the frequency f 2 making amplitude become peak value P2 becomes lower than described frequency f 1 (characteristic of intrinsic vibration is to lower frequency side displacement).Thus, the performance of regarding weight level floor impact sound is improved.
At this, when making the characteristic of intrinsic vibration to lower frequency side displacement as described above, the people be positioned on flooring structure easily feels floor vibration, but, adopt flooring structure 1 involved in the present invention as above, this floor vibration can be reduced.
Specifically, as shown in the solid line of Fig. 4, the energy absorption that the flooring structure 1 possessing connecting member 5 is brought by the shear strain of vibration-damped component 5b, the vibration of each floor plate 4 of can decaying.Therefore, as shown in arrow Y2, the peak value P2 of amplitude can be reduced to peak value P3.
Thus, and in the diagram with compared with the comparative example shown in chain double-dashed line, as shown in arrow Y3, heavyweight floor impact sound can be reduced, and as shown in arrow Y2, can floor vibration be reduced.
As mentioned above, because multiple floor plates 4 are interconnected by connecting member 5, therefore when a floor plate 4 will rotate or reverse, vibration-damped component 5b produces shear strain between this floor plate 4 and cover plate 5a, thus can suppress (decay) described rotation or torsion.
Therefore, by rotation and the torsion of the floor plate 4 on restriction joist 2, can suppress to produce vibration on flooring structure 1.
In addition, according to the 1st embodiment, following effect can be obtained.
Because flooring structure 1 possesses anti-vibration member 3, as mentioned above, the reduction of heavyweight floor impact sound and the reduction of floor vibration can be realized in the lump.
In addition, because connecting member 5 is configured to the whole upper surface covering multiple floor plates 4, therefore can limit rotation and the torsion of floor plate 4 on the whole surface on floor, effectively suppress to produce vibration on flooring structure 1.
Because cover plate 5a is made up of the steel plate of thickness 4.5mm, so can give to cover plate 5a the bending strength and hot strength that can bear the power of bending direction and the power of draw direction produced on cover plate 5a because of the rotation of floor plate 4 and torsion.
