JP4256493B2 - Low-frequency vibration isolation structure for roof and / or bottom plate of aluminum sash bay window - Google Patents

Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an anti-vibration structure for a roof and / or a bottom plate of an aluminum sash bay window used in a building near a place where low-frequency noise occurs such as an airfield or a base.
[0002]
[Prior art]
As shown in FIG. 5, the roof 1 and the bottom plate 2 of the aluminum sash bay window are composed of an outer material 3 made of a long and wide aluminum extrusion mold material, and an inner material 4 made of steel or aluminum for supporting the outer material 3. ing.
[0003]
[Problems to be solved by the invention]
However, according to such a configuration, the outer member 3 and the inner member 4 form a hollow portion 5, which is sound-insulating in the low range due to resonance transmission in the vicinity of low-frequency noise such as an airfield or a base. Has become an obstacle for the purpose of reducing indoor noise.
[0004]
Therefore, for example, foaming damping material 5 (for example, registered trademark Grite) that also serves as heat insulation is adhered to the inside of the outer material 3 by means such as spraying to prevent the generation of noise due to resonance. Is a long and wide aluminum extrusion mold, and its thickness has a limit due to extrusion processing, and therefore there is a problem that it is impossible to prevent the generation of resonance due to vibration.
[0005]
[Means for Solving the Problems]
Accordingly, the present invention provides a low-frequency vibration-proofing of a roof and / or a bottom plate of an aluminum sash bay window composed of an outer material made of a long and wide aluminum extrusion mold and an inner material made of steel or aluminum that supports the outer material. in the structure, the inside of the roof and / or bottom plate inside properly the inner material of the outer member of ridge-like vibration-proof material in the longitudinal direction of the roof and / or bottom plate in the vicinity of the center in the width direction of the roof and / or bottom plate was the inner member and the rigid structure also outside material properly disposed linearly inside the inner or inner member of the outer member of the roof and / or bottom plate by attaching damping material, bay windows by the inner material of the roof and / or bottom plate It is characterized by being fixed to the outer frame and the casing .

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings.
First Embodiment FIG. 1 is an explanatory view showing a first embodiment. In the figure, reference numeral 6 denotes a roof, and an outer member 7 and an outer member 7 made of a long and wide aluminum extrusion die are shown. It is comprised with the inner material 8 by the steel and aluminum which support.
[0007]
Reference numeral 9 denotes a bottom plate, which is also composed of an outer material 7 made of a long and wide aluminum extrusion mold material and an inner material 8 made of steel or aluminum for supporting the outer material 7.
The roof 6 and the bottom plate 9 are fixed to the bay window outer frame 10 and the casing 11 with screws or the like by the inner member 8.
[0008]
Reference numeral 12 denotes an anti-vibration material, which is a long material whose cross-sectional shape is made of aluminum, steel, stainless steel, synthetic resin, wood, or the like. Such an anti-vibration material 12 is fixedly arranged in the longitudinal direction of the roof 6 and / or the bottom plate 9 in the vicinity of the center in the width direction of the roof 6 and / or the bottom plate 9 so that the outer material 7 has a rigid structure. The attachment means may be any means such as adhesion with an adhesive, adhesion with a double-sided tape, spot welding and the like.
[0009]
Further, the cross-sectional shape is not limited to the above-mentioned angle shape. For example, as shown in FIG. 2, the cross-sectional shape may be any shape such as a triangle, a quadrangle, a mountain shape, a corrugated shape, and the attached outer member 7 has a rigid structure. Any shape that can be configured may be used.
In addition, although the arrangement | positioning location is attached to the inner side of the outer material 7 in drawing, it may be made to protrude outside and when it is attached to the inner side, the appearance is good. If installed outside, it has the effect of preventing the rain from blowing up.
[0010]
In the above description, the vibration isolator 12 is attached to the outer member 7. However, the vibration isolator 12 may be attached to the inner member 8 in the same manner, and the vibration isolator 12 may be attached to both the outer member 7 and the inner member 8. It may be attached.
Reference numeral 5 denotes a foaming vibration damping material (for example, registered trademark Grite) which also serves as heat insulation attached to the inside of the outer material 7 and / or the inner material 8. In addition, in the case where the appearance is not particular, it may be attached to the outside.
[0011]
Further, although not shown, a vibration-damping paint (for example, registered trademark Gelnac) may be applied instead of the vibration-damping material 5.
Thus, by attaching the vibration isolator 12 to the outer member 7 and / or inner member 8 of the roof 6 and / or the bottom plate 9, the outer member 7 and / or inner member 8 has a rigid structure, and sound insulation in a low sound range is achieved. As can be seen from FIG. 3, the sound transmission loss is improved in a low frequency range of 500 Hz or less.
[0012]
Second Embodiment In the following description, the same parts as those described above will be described using the same reference numerals.
FIG. 4 is an explanatory view showing a second embodiment. In the figure, reference numeral 6 denotes a roof, which is an outer material 7 made of a long and wide aluminum extrusion mold material, and steel or aluminum that supports the outer material 7. It is comprised by the inner material 8.
[0013]
Reference numeral 9 denotes a bottom plate, which is also composed of an outer material 7 made of a long and wide aluminum extrusion mold material and an inner material 8 made of steel or aluminum for supporting the outer material 7.
In the vicinity of the center in the width direction of the outer material 7 of the roof 6 and / or the bottom plate 9 described above, the ridge-shaped vibration isolating material 13 is integrally formed in the longitudinal direction of the roof 6 and the bottom plate 9 to make the outer material 7 a rigid structure. Although this formation location is formed on the inner side of the outer member 7 in the drawing, it may be formed so as to protrude outward, and the same effect as described above can be obtained.
[0014]
When the vibration isolator 13 is molded, a thick portion having a desired width that forms an angle with the vibration isolator 13 is preferably formed on the base portion, although not shown.
In the above description, the vibration isolator 13 is formed on the outer member 7. However, the inner member 8 may be provided in the same manner as described above. Further, both the outer member 7 and the inner member 8 are provided with the vibration isolator. 13 may be formed.
[0015]
Reference numeral 5 denotes a foaming vibration damping material (for example, registered trademark Grite) which also serves as heat insulation attached to the inside of the outer material 7 and / or the inner material 8. In addition, in the case where the appearance is not particular, it may be attached to the outside.
Further, although not shown, a vibration-damping paint (for example, registered trademark Gelnac) may be applied instead of the vibration-damping material 5.
[0016]
The roof 6 and the bottom plate 9 are fixed to the bay window outer frame 10 and the casing 11 with screws or the like by the inner plate 8.
As described above, the outer material 7 and / or the inner member 8 is integrally formed with the outer member 7 and / or the inner member 8 of the roof 6 and / or the bottom plate 9, so that the outer member 7 and / or the inner member 8 has a rigid structure. As in the case of the embodiment, the sound insulation in the low sound range is remarkably improved.
[0017]
In each of the above-described embodiments, the description has been given on the case where the vibration isolating material is provided in a single row in the longitudinal direction of the roof and the bottom plate near the center in the width direction of the outer material and / or the inner material. Of course, more effects can be expected.
[0018]
