Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a vibration damping structure, and more particularly to a vibration damping structure suitable for a general wooden house or the like.
[0002]
[Prior art]
FIG. 1 is a diagram showing an embodiment of the present invention. Since the structure of pillars and the like is the same as that of the prior art, the prior art will be described with reference to FIG.
[0003]
A foundation 2 is provided on the concrete foundation 1, and pillars 3 and 4 are erected on the foundation 2, and beams 5 are provided on the upper portions of the pillars 3 and 4.
[0004]
Various types of vibration control devices have been proposed which are provided in the wall surface 6 including the base 2 of the wooden house, the columns 3 and 4 and the beam 5 and prevent the building from resonating and collapsing due to the vibration of the earthquake.
[0005]
As an example thereof, as shown in FIG. 1, a lower panel 6 for transmitting the horizontal displacement of the base 2 and an upper panel 7 for transmitting the horizontal displacement of the beam 5 are provided, and the vibration control means is provided between the two panels. There is one provided with a damper 9.
[0006]
Although not shown as another method, there is also known a vibration damping device in which one of two metal panels sandwiching a viscous rubber is fixed to the base 2 and the other is fixed to the pillar 3.
[0007]
Inside the wall surface provided with such vibration damping means, an internal structure such as a damper 9 is provided, which is a complex shaped space.
[0008]
For this reason, the glass wool etc. which can change a shape easily were used as a heat insulating material of a house.
[0009]
[Problems to be solved by the invention]
However, in such a vibration damping structure, the vibration damping means is provided in the wall surface, and since this vibration damping means is made of metal, condensation tends to occur. In addition, the gap between the vibration control means and the outer wall (not shown) on the front side in the figure is small, and glass wool does not enter so much that it is more likely to condense. There was a problem that the wood was corroded.
[0010]
The present invention relates to a vibration damping structure that solves such problems.
[0011]
[Means for Solving the Problems]
In order to solve the above problems, the present invention has the following features.
[0012]
The present invention provides a metal damping means for applying a damping force to a deformation of one wall surface composed of a base and a beam and two adjacent columns, between the base and the beam, In the vibration damping structure provided between at least one of the beams and the column, between the outer wall provided on the one wall surface and the vibration damping means, a heat insulating panel is partially provided in the wall surface space. In addition, the heat insulating material made of a deformable material is provided in the other wall surface space of the one wall surface.
[0013]
DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the present invention will be described with reference to FIGS. In addition, FIG. 1 is a figure before arrange | positioning the below-mentioned heat insulation panel 10 and glass wool 11, and FIG. 2 is a figure after arrange | positioning both members.
[0014]
A base 2 made of wood is provided on the concrete foundation 1, and pillars 3 and 4 are erected on the base 2. A beam 5 is provided above the columns 3 and 4.
[0015]
Further, between the adjacent columns 3 and 4, a plurality of trunk edges 12 are provided horizontally on both sides of the inner wall side and the outer wall side.
[0016]
A lower panel 7 is fixed to the base 2 as a displacement transmission means for transmitting the horizontal displacement of the base 2, and the beam 5 is also used as a displacement transmission means for transmitting the horizontal displacement of the beam 5. The upper panel 8 is fixed, and a damper 9 as a vibration damping means is provided between the panels.
[0017]
As the damper 9, a hydraulic shock absorber in which oil is sealed in a metal cylinder and a rod protrudes from one end through a seal, a friction damper that generates a damping force due to friction with the metal cylinder, or the like is used. .
[0018]
Between the damper 9 in the wall surface and an outer wall (not shown) provided on the front side in the figure, a plate-like heat insulation panel 10 made of foamed urethane is provided. This heat insulation panel 10 is provided so as to be sandwiched between two trunk edges 12 and is positioned in the vertical direction. The front-rear direction is positioned by the upper and lower panels 6 and the outer wall.
[0019]
As described above, in the present embodiment, the heat insulating panel 10 is fixed using the existing trunk edge 12 or the like, but if there is no such thing, it may be fixed inside the outer wall material with an adhesive or the like. Good.
[0020]
A gap is provided between the heat insulating panel 10 and the pillars 3 and 4 on both sides to prevent the heat insulating panel 10 from cracking when the wall surface is deformed by an earthquake.
[0021]
Further, the remaining wall surface space is filled with cotton-like glass wool 11. This glass wool may be cotton-like, but it may be glass wool of a type attached between two aluminum foils, or crushed cellulose fiber or urethane, and can be easily deformed. Anything can be used. However, a cotton-like or powdery thing is desirable.
[0022]
With the above configuration, resonance is suppressed by the damper 9 in the event of an earthquake, and a vibration control effect is obtained.
[0023]
In addition, even when condensation is likely to occur due to a temperature difference between the inside and outside of the room, a heat insulating panel 10 having a high heat insulating effect is provided in a narrow gap between the metal damper 9 and the outer wall where condensation is likely to occur. Condensation is difficult to occur, rusting of the damper 9 can be prevented, and corrosion of the wood can also be prevented.
[0024]
In addition, since glass wool or the like that can be easily deformed is provided in other complicated spaces, the whole can be filled with a heat insulating material, and condensation can be effectively prevented.
[0025]
Furthermore, the upper and lower panels 7, 8 and the inner wall and the heat insulating panel 10 can secure a space with only the side surface opened, and the damper 9 is provided in this space, so that glass wool is slightly in this space from the side opening. Although it penetrates, it is possible to prevent a large amount of glass wool from touching the damper, and it is possible to prevent the rod or seal of the damper from being damaged by the glass wool. Furthermore, by providing a heat insulating panel between the inner wall and the damper 9, it is possible to further prevent the glass wool from entering.
[0026]
In the above-described embodiment, the vibration control device using the panels 7 and 8 and the damper 9 is shown. However, the vibration control device is not particularly limited, and the pillar 3 adjacent to the base 2 or the beam 5 is used. , 4, the present invention is effective if it is a metal damping device that gives a damping effect to the deformation of the quadrangle.
[0027]
In the above embodiment, the first floor portion has been described, but the same applies to the second floor and the third floor. In this case, the first-floor beam is the second-floor base, and the second-floor beam is the third-floor. It becomes the foundation part.
[0028]
In addition, the heat insulation panel of the said embodiment may be various heat insulation panels, such as a wood fiber type, a polystyrene type, a phenol type other than urethane type.
[0029]
【The invention's effect】
According to the present invention, a heat-insulating panel having a high heat-insulating effect is provided between the metal damping means that is likely to condense and the outer wall, and a heat-insulating material such as glass wool that is easily deformed is provided in the other wall space. Therefore, sufficient heat insulation can be obtained and condensation can be prevented.
