DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
Hereinafter, embodiments of the invention will.
be described w~.th reference to the accompanying drawings.
First embodiment Fig_ 1 is a schematic perspective view of a hollow panel according to a first embodiment, and Fig_ 2 is an end view of a part of the hol.~.ow panEl.
Referring to the figures, a hollow panel 10 that can be used as a construction material such as a wall panel, a floor panel, and a ceiling panel comprises a pair of flat outer sides 11 which are substantially parallel to each other, and plural.
hollow portions 12 which are positioned betweEn the outer sides 11 so as to be arranged in a substantially same plane.
Each of the hollow portions 12 has a shape which J
linearly extends in a direction perpendicular to the plane of the sheet of Fig. 2. The hollow portions 12 are formed so that partition walls 13 which axe arranged at predetermined intervals in the lateral b directions in the figure are inclined by an approximately same angle and to alternately different directions. As a result, each of the hollow portions J.2 shows an approximately trapezoidal section shape_ In the embodiment, first hollow portions 12A having a smaller J.atexal width w1, and second hollow portions having a lateral width W2 which is larger than the lateral width W1 are formed so as to be alternately positioned along the lateral. direction in Fig. 2, so that the adj acent hollow portions 12A and 12B are disposed to be alternately different or nonuniform in sectional area. In the figure, the lateral widths W1 and W2 of the first and second hollow portions 12A and 12B are indicated as those at the respective middle positions in the panel thickness direction because of the following reason. since the partition walls 13 are inclined, the thicknesses are shown with reference to the respective middle positions for the sake of 2o convenience. Altex~natzvely, the partition walls 13 may not be inclined, and may be modified so as to have a sinusoidal waveform, or an approximately pulse-like waveform so that the partition walls 13 are perpendicular to the outer sides in the panel thickness direction. As shown in Fig. 3, the hollow panel 10 may further comprise third hollow portions 12C which have a more larger width.
In the hollow panel. 10, the lateral ends 10A
1.0 in Fig. 1 have a closed structure in which the hallow portions 12 are not formed. ,According to the configuration, the rigidity is provided so that lateral end portions of the outer sides 11 are prevented from being bent in a direction 15 perpendicular to the panel plane, whereby the shape retention property can be maintained.
According to the thus configured first embodiment, when the whole of the single hollow 20 panel 10 is considered, the first and second hollow portions 12A and 12B are formed so as to have different sectional areas, and hence the relationships are attained in which the surface densities of areas substantially corresponding to 2~ the hollow portions 12A and 12B are different.
Therefore. a structure where the resonance frequency of the panel due to the sectional areas or sizes of the hollow portions is riot unifoxm in the panel plane but dispersed is formed, and a lack T of sound insulation caused by resonance at a specific frequency can be effectively suppressed_ Next, other embodiments of the invention will be described. Tn the following description, components which are identical with or equivalent to those of the first embodiment are denoted by the same reference numerals, and their description is omztted oz' simplified.
1.5 Second Embodiment Fig. 9 shows a second embodiment ofi the invention. The embodiment is CharaCtex'zZed in that, although the ho J. low portions 12 have the same sectional area, different thicknesses x1. and T2 of the partition walls 13 between the hollow portions 12 alternately appeax. The th~.ckz~esses are set so as to have a relationship of T1 > T2.
In the second embodiment also, the area of the 2:~ thickness T1 is higher in surface density than that of the thickness T2, or higher in rigidity.
Therefore, the embodiment has a structure where the panel resonance frequency is not uniform in the plane of the hollow panel J.O, and can exert the same b sound insulation effect as that of the first embodiment.
Third Embodiment Figs. 5 and 6 show a third embodiment of the 14 invention. T~-ce embodiment is characterized in that a solid portion 15 is formed in a specific region where a hollow portion is to be originally formed.
As shown in Fig. 5, the sol,i.d poxtzon 15 may be foz~zned linearly in a region corresponding to a single 15 hollow portion, or alternatively formed so as to extend over plural hollow portions 12. xn the ~.J.lustrated example, the solid portion 15 linearly extends. However, the manner of the extension ~.s not J.imited to a linear one. It is possible to say 20 that the embodiment is realized by extrEmely increasing the thicknesses of specific PneS Of the partition waJ.7.s 13.
Also the embodiment can exert the same effect 25 as that of the afore-described embodiments.
Fourth Embodiment Fig. 7 shows a fourth embodiment of the invention. In the embodiment, a rod-like member 16 serving as a solid portion foaming member is inserted into one of the hollow portions 12. The rod--like member has a section shape which generally corresponds to a section shape of the hollow portion. There~oxe, the surface density is partially differentiated, so that the above-mentioned sound insulation effect is attained. This configuration can be easily applied to a prevz.ouslx shapEd hollow panel, so that the invention can be applied to an existing hollow panel. When the insertion position of the rod-like member 16 is changed, it is possible to arbitrary determine the region of a different surface der~szty.
As shown in Fig. B, the rod-like member 16 may be placed in a direction intersecting with, for example, perpendicular to the direction along which the hollow portions 12 extend.
2u As described above, although the best configuration, method, and the J~ike for embodying the invention have been disclosed in the above description, the invention is not limited to them.
Namely, although the invention has been illustrated and described with respect to specific embodiments, these skilled in the art can variously modify as required the abo~re-described embodiments with respect the shape, the position; the arrangement, or the like without departing from the technical concept and objECt of the invention. Fox example, the embodiments and modifications can be arbitrarily combined with each other. The number of the rod-like member 16 may be adEquately increased or decreased as required. Various kinds of the rod-like members 16 of different masses may be used to enable the distribution of the surface density to be finely differentiated.
As described above, according to the invention, i.t is possible to provide a hollow panel.
that exerts an excellent effect in which the resonance frequency of the panel is not uniform in the paz~eJ. pZar~e but dispersed and hence a lack of sound zz~sulati.on due to resonance can be Z5 suppressed, and which cannot be exerted in the conventional art. Since the hollow portions are arranged in a substantially same plane, the thickness of the hollow panel ca.n be reduced.
In the case where the configuration in which a rod~-like member is inserted into a hollow portion is employed, a portion where the surface density is partially dif~ezentiated can be axbztrarily determined to be placed, and therefore the invention can be easily applied to suppress a lack of sound insulation.

As shown in Fig. 3, the hollow panel 10 may further comprise third hollow portions 12C which have a more larger width.
In the hollow panel. 10, the lateral ends 10A
1.0 in Fig. 1 have a closed structure in which the hallow portions 12 are not formed. ,According to the configuration, the rigidity is provided so that lateral end portions of the outer sides 11 are prevented from being bent in a direction 15 perpendicular to the panel plane, whereby the shape retention property can be maintained.
According to the thus configured first embodiment, when the whole of the single hollow 20 panel 10 is considered, the first and second hollow portions 12A and 12B are formed so as to have different sectional areas, and hence the relationships are attained in which the surface densities of areas substantially corresponding to 2~ the hollow portions 12A and 12B are different.
Therefore. a structure where the resonance frequency of the panel due to the sectional areas or sizes of the hollow portions is riot unifoxm in the panel plane but dispersed is formed, and a lack T of sound insulation caused by resonance at a specific frequency can be effectively suppressed_ Next, other embodiments of the invention will be described. Tn the following description, components which are identical with or equivalent to those of the first embodiment are denoted by the same reference numerals, and their description is omztted oz' simplified.
1.5 Second Embodiment Fig. 9 shows a second embodiment ofi the invention. The embodiment is CharaCtex'zZed in that, although the ho J. low portions 12 have the same sectional area, different thicknesses x1. and T2 of the partition walls 13 between the hollow portions 12 alternately appeax. The th~.ckz~esses are set so as to have a relationship of T1 > T2.
In the second embodiment also, the area of the 2:~ thickness T1 is higher in surface density than that of the thickness T2, or higher in rigidity.
Therefore, the embodiment has a structure where the panel resonance frequency is not uniform in the plane of the hollow panel J.O, and can exert the same b sound insulation effect as that of the first embodiment.
Third Embodiment Figs. 5 and 6 show a third embodiment of the 14 invention. T~-ce embodiment is characterized in that a solid portion 15 is formed in a specific region where a hollow portion is to be originally formed.
As shown in Fig. 5, the sol,i.d poxtzon 15 may be foz~zned linearly in a region corresponding to a single 15 hollow portion, or alternatively formed so as to extend over plural hollow portions 12. xn the ~.J.lustrated example, the solid portion 15 linearly extends. However, the manner of the extension ~.s not J.imited to a linear one. It is possible to say 20 that the embodiment is realized by extrEmely increasing the thicknesses of specific PneS Of the partition waJ.7.s 13.
Also the embodiment can exert the same effect 25 as that of the afore-described embodiments.
Fourth Embodiment Fig. 7 shows a fourth embodiment of the invention. In the embodiment, a rod-like member 16 serving as a solid portion foaming member is inserted into one of the hollow portions 12. The rod--like member has a section shape which generally corresponds to a section shape of the hollow portion. There~oxe, the surface density is partially differentiated, so that the above-mentioned sound insulation effect is attained. This configuration can be easily applied to a prevz.ouslx shapEd hollow panel, so that the invention can be applied to an existing hollow panel. When the insertion position of the rod-like member 16 is changed, it is possible to arbitrary determine the region of a different surface der~szty.
As shown in Fig. B, the rod-like member 16 may be placed in a direction intersecting with, for example, perpendicular to the direction along which the hollow portions 12 extend.
2u As described above, although the best configuration, method, and the J~ike for embodying the invention have been disclosed in the above description, the invention is not limited to them.
Namely, although the invention has been illustrated and described with respect to specific embodiments, these skilled in the art can variously modify as required the abo~re-described embodiments with respect the shape, the position; the arrangement, or the like without departing from the technical concept and objECt of the invention. Fox example, the embodiments and modifications can be arbitrarily combined with each other. The number of the rod-like member 16 may be adEquately increased or decreased as required. Various kinds of the rod-like members 16 of different masses may be used to enable the distribution of the surface density to be finely differentiated.
As described above, according to the invention, i.t is possible to provide a hollow panel.
that exerts an excellent effect in which the resonance frequency of the panel is not uniform in the paz~eJ. pZar~e but dispersed and hence a lack of sound zz~sulati.on due to resonance can be Z5 suppressed, and which cannot be exerted in the conventional art. Since the hollow portions are arranged in a substantially same plane, the thickness of the hollow panel ca.n be reduced.
In the case where the configuration in which a rod~-like member is inserted into a hollow portion is employed, a portion where the surface density is partially dif~ezentiated can be axbztrarily determined to be placed, and therefore the invention can be easily applied to suppress a lack of sound insulation.
