Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to, for example, a vibration damping device which is mounted between pillars of a skeleton and forms a wall surface together with a panel, and is used to reduce shaking due to an earthquake or traffic vibration. The present invention relates to a vibration damping device suitable for use in a low-rise building.

[0002]

2. Description of the Related Art Conventionally, as a vibration damping device as described above, for example, a horizontal member is installed between columns so as to face each other, and a pair of first support shafts and a pair of second support members are mounted on these horizontal members. A first plate rotatably supported by the first support shaft, and a second plate rotatably supported by the second support shaft and facing the first plate. There is a configuration in which a viscoelastic body is provided between, in this vibration damping device, by arranging a plurality of types of viscoelastic bodies having different mechanical characteristics in the longitudinal direction of the horizontal member, vibration having a large amplitude and Any of the vibrations having a small amplitude can be reduced (Japanese Patent Application Laid-Open No. 9-170352).

[0003]

However, in the above-described conventional vibration damping device, since a plurality of types of viscoelastic bodies are arranged in the longitudinal direction of the horizontal member, an effect of suppressing vibrations having different amplitudes is expected. Although it is possible, if you try to arrange as many viscoelastic bodies as necessary to suppress various vibrations,
The length dimension of the lateral member becomes large.

[0004] This vibration damping device accommodates a horizontal member between columns having dimensions determined for convenience of being arranged at a portion other than the opening of a building, that is, for convenience of being arranged at a FIX portion. Inevitably, there is a problem that the vibration damping device may not be used depending on the situation, and solving this problem has been a conventional problem.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and is capable of reliably reducing both shaking caused by an earthquake and traffic vibration without being restricted in use. It is intended to provide a vibration damping device.

[0006]

According to a first aspect of the present invention, there is provided a vibration damping device, comprising: an earthquake vibration damping rubber; a traffic vibration damping rubber thinner than the earthquake vibration damping rubber; Elongate first holder having a connecting portion with the panel,
A second holder having an elongated shape having a connection portion with the frame or a panel mounted on the frame, and a third holder having an elongated shape having a connection portion with the first holder;
The holder and the third holder are arranged side by side in the indoor and outdoor directions,
The seismic vibration damping rubber positioned along the longitudinal direction between the first holder and the second holder is joined to each of the holders, and the rubber is positioned along the longitudinal direction between the second holder and the third holder. The traffic vibration damping rubber thus formed is joined to both holders, and the structure of the vibration damping device is a means for solving the conventional problems.

According to a second aspect of the present invention, there is provided a vibration damping device comprising: an earthquake vibration damping rubber; a traffic vibration damping rubber thinner than the earthquake vibration damping rubber; and a skeleton or a panel mounted on the skeleton. An elongated first holder having a connecting portion and a second elongated holder having a connecting portion with a panel mounted on a frame.
A first holder, a second holder, and a third holder having an elongated shape having a connection portion with the first holder;
The holders are arranged side by side in the indoor and outdoor directions, and the first holder and the second
The vibration and vibration damping rubber positioned along the longitudinal direction between the holders is joined to each of the holders, and the traffic vibration damping is positioned between the second holder and the third holder along the longitudinal direction. Rubber is bonded to both holders, and the structure of the vibration damping device is used as means for solving the conventional problems.

In the vibration damping device according to a third aspect of the present invention, the third holder is detachable from the first holder, and the third holder is mounted side by side with the first and second holders in the indoor and outdoor directions. In such a case, the traffic vibration damping rubber is positioned along the longitudinal direction between the second holder and the third holder and is joined to both holders, respectively. , At least one of the first holder and the second holder has an earthquake vibration damping rubber compression projecting toward the other holder by a distance slightly smaller than the thickness of the earthquake vibration damping rubber. A deformation limiting portion is provided, and at least one of the second holder and the third holder projects toward the other holder by a distance slightly smaller than the thickness of the traffic vibration damping rubber. That is a traffic vibration damping rubber compressive deformation limiting portion provided configuration.

[0009] In the vibration damping device according to the present invention, the length (dimension in the left-right direction) is determined according to the length of the panel, that is, determined according to the dimension between the columns, and the height (up and down). Regarding the direction dimension), if it is too large, the vibration damping device itself will rotate regardless of the magnitude of the viscoelasticity of the seismic vibration damping rubber and the traffic vibration damping rubber.
It is desirable to stop it at about 0 mm.

Next, when considering the thickness (dimensions in the indoor and outdoor directions) of the vibration damping device according to the present invention, timber of 90 to 110 mm square is usually used for the beam constituting the wall. It is preferable to suppress the thickness to about 70 mm in consideration of the thickness of the installed brace.

Here, according to the standard of earthquake-resistant building, seismic intensity 6
The floor displacement H is set to H / 200 so that the house is not collapsed when an earthquake having a magnitude of (shaking acceleration 250 to 400 gal) to seismic intensity 7 (shaking acceleration 400 to 1500 gal) occurs. You.

That is, in the case of a house having a floor height H of 3500 mm, when an earthquake having a seismic intensity of 6 or more occurs, an interlayer displacement exceeding 17.5 mm is generated. Use a material obtained by heating and kneading the main components of petroleum asphalt and thermoplastic rubber, and if the deformation of three times (300%) of the thickness is allowed, reduce the thickness of the traffic vibration damping rubber. Assuming that the thickness of the seismic vibration damping rubber is 5 mm and the thickness of the seismic vibration damping rubber is 10 mm, according to the data on the low-rise building of the third floor or lower of the steel frame (or wooden) frame structure, as shown in the graph of FIG. In an amplitude range T of traffic vibration smaller than the amplitude range S, the traffic vibration damping rubber has a greater damping effect than the seismic vibration damping rubber, but as shown in the graph of FIG.
Is 15 mm, which is less than the interlaminar displacement amount of 17.5 mm when an earthquake with a seismic intensity of 6 or more occurs. Therefore, the traffic vibration damping rubber alone breaks.

On the other hand, the seismic vibration damping rubber has an allowable limit of deformation M of 30 mm, so that it does not break even when an earthquake with a seismic intensity of 6 or more occurs, and exhibits high vibration damping properties.

Therefore, in the vibration damping device according to the present invention, the thickness of the seismic vibration damping rubber having the above composition is 10 mm, the thickness of the traffic vibration damping rubber is 5 mm, and the thickness of the entire device exceeds 70 mm. It is preferable to use a plurality of vibration damping rubbers laminated in a range that does not exist. In this case, seismic vibration damping rubber (or traffic vibration damping rubber)
Can be laminated by sandwiching it with traffic vibration damping rubber (or seismic vibration damping rubber), and a configuration can be adopted in which earthquake vibration damping rubber and traffic vibration damping rubber are alternately laminated. be able to.

As shown in the graph of FIG. 6, the seismic vibration damping rubber of the vibration damping device according to the present invention has an effect of attenuating traffic vibration, though inferior to that of traffic vibration damping rubber. However, in the present invention, the vibration damping rubber having the remarkable effect of damping the seismic vibration is used as the seismic vibration damping rubber, and the thin vibration damping rubber having the remarkable effect of damping the traffic vibration is used as the traffic vibration damping rubber. And

[0016]

In the vibration damping device according to the first and second aspects of the present invention, the seismic vibration damping rubber for suppressing the vibration having a large amplitude and the traffic vibration damping rubber having a small thickness for suppressing the vibration having a small amplitude comprise the first vibration damping rubber. Since the holder, the second holder, and the third holder are arranged side by side in the indoor and outdoor directions, even if a plurality of vibration damping rubbers having different thicknesses are arranged to suppress vibrations having different amplitudes, the width in the left-right direction is different from the conventional case. The increase is avoided.

In the vibration damping device according to claim 3 of the present invention,
With the above-described configuration, two types of specifications can be selected: a specification in which only the seismic vibration damping rubber is attached, and a specification in which the traffic vibration damping rubber is attached together with the seismic vibration damping rubber. In other words, it is easy to change from a high-rise building vibration damper to a low-rise building vibration absorber that is heavy and hardly affected by high-frequency traffic vibration. As a result, there is no need to separately manufacture a vibration damping device for a high-rise building and a vibration damping device for a low-rise building, and the management becomes easier by that much.

In the vibration damping device according to claim 4 of the present invention,
The seismic vibration damping rubber compression deformation limiting portion provided on at least one of the first holder and the second holder prevents the seismic vibration damping rubber from being excessively compressed during manufacturing or transportation. And likewise,
The traffic vibration damping rubber is prevented from being greatly shrunk during manufacturing or transportation by the traffic vibration damping rubber compression deformation limiting portion provided on at least one of the second holder and the third holder. Therefore, the damping function of the damping rubber is maintained for a long time.
