DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building provided with a vibration control structure against an earthquake.

[0002]

2. Description of the Related Art In a high-rise building or the like, in order to reduce the shaking caused by an earthquake, a passive weight for absorbing vibration by arranging a weight having a vibration characteristic similar to that of the building in a building body has conventionally been used. Incorporation of a vibration damping device or an active vibration damping device that mechanically controls vibration has been performed. In a unit-type building for a detached house, an outer wall is constituted by an outer wall panel, and the outer wall panel is sandwiched between a waterproof foam polyethylene stud and a small pillar (stud) for fixing the outer wall panel. It is fixed to a small pillar for fixing the outer wall panel.

[0003]

SUMMARY OF THE INVENTION Incorporating a passive vibration damping device or a mechanical vibration damping device into a building body is necessary as a building structure even if it can be applied to a large-scale high-rise building or the like. Since a device other than a simple one is required, it may be difficult to apply to a medium- to small-scale medium to low-rise building, particularly a unit-type building for a detached house, from the viewpoint of installation space and cost.

[0004] Polyethylene foam has a vibration damping property due to elastic deformation. However, in a conventional building, a polyethylene film having a very low frictional resistance is bonded to a joint surface of the polyethylene foam to an outer wall panel. Even when a relative displacement occurs between the outer wall panel and the small pillar for fixing the outer wall panel during an earthquake, the outer wall panel slides against the polyethylene film on the polyethylene foam surface, and vibration energy is not transmitted to the polyethylene foam. Polyethylene foam exhibits only a waterproof effect and does not exhibit a vibration damping effect.

In view of the above, the present invention focuses on the above-described problems, and it is possible to attenuate the building vibration with the structure of the building structure itself without incorporating a special passive vibration damping device or a mechanical vibration damping device. It is another object of the present invention to provide a building in which a damping effect can be obtained by a waterproof material sandwiched between an outer wall panel and a small pillar for fixing the outer wall panel.

In order to achieve the above object, according to the first aspect of the present invention, a decorative material for covering a joint between panels constituting an inner wall, a ceiling or a floor is provided at a corner in a room. In the building provided along, the decorative material is fixed to the panel with an adhesive exhibiting vibration damping properties.

[0007] According to this configuration, since the decorative material is fixed to the panel with an adhesive exhibiting vibration damping properties, the fixing strength of the decorative material to the panel is increased, and the panels are connected by the decorative material. This makes it possible to increase the rigidity against deformation of the inner wall, ceiling or floor due to external force and suppress the shaking of the entire building, and furthermore, it acts as an anti-vibration rubber due to the adhesive layer existing at the fixed part of the decorative panel. It is possible to obtain a vibration damping (vibration prevention) effect of damping vibration.

According to the second aspect of the present invention, in a building having a steel frame structure in which an outer wall panel is attached to a skeleton steel frame, the outer wall panel has a weight corresponding to an absorber weight, and the upper or lower part is movable.

According to this configuration, a vibration damping device is constructed in which the outer wall panel is weighted by the absorber and the frame steel frame is a spring. When the outer wall panel is displaced by the vibration of the building, the frame steel frame supporting the frame is elastically deformed. By this elastic deformation, vibration energy is absorbed, and the vibration of the building can be attenuated. In the invention according to claim 3,
In a building in which a wall panel is attached to a skeleton steel frame, the wall panel is displaceably attached to the skeleton steel frame, and a vibration absorbing member is interposed between the wall panel and the skeleton steel frame. Configuration.

According to the fourth aspect of the invention, the vibration absorbing member is made of an adhesive exhibiting an elastic property after curing. According to this configuration, when the wall panel is displaced with respect to the skeleton steel frame due to the vibration of the building, the displacement is attenuated by the elastic deformation (internal friction) of the adhesive forming the vibration absorbing member, and the shaking of the building is reduced. .

According to a fifth aspect of the present invention, the vibration absorbing member is an adhesive tape having elasticity. According to this configuration, when the wall panel is displaced with respect to the skeleton steel frame due to the vibration of the building, the displacement is attenuated by the elastic deformation (internal friction) of the adhesive tape forming the vibration absorbing member, and the shaking of the building is reduced. .

In the invention according to claim 6, the wall panel has a weight corresponding to an absorber weight, and is attached to the frame steel frame so as to vibrate in accordance with the natural period of the vibration of the building. . In this configuration, the wall panel vibrates in response to the natural period of the vibration of the building, and the vibration is attenuated by the vibration absorbing member, and the shaking of the building is reduced.

The building according to claim 7, wherein in the building having an outer wall panel, a tape made of a damping material having waterproof property is sandwiched between the outer wall panel and a pillar for fixing the outer wall panel, and the tape is provided. Has a structure in which one surface is adhered or adhered to the column and the other surface is adhered or adhered to the back surface of the outer wall panel in a state of high frictional resistance. With this configuration, when a relative displacement occurs between the outer wall panel and the column for fixing the outer wall panel during an earthquake, vibration energy is transmitted to the tape, and the tape exerts a vibration damping effect.

It is bonded and fixed to the inner wall panel 5 and the ceiling panel 6 so as to cover the joint between the ceiling panel 6 and the inner panel.

Thus, the inner wall panel 5 and the ceiling panel 6
And the rigidity against deformation due to external force is increased, and the shaking of the whole building is suppressed. In addition, a small or medium-sized earthquake, traffic vibration, or external force such as wind does not cause a gap or a gap between the inner wall panel 5 and the ceiling panel 6, so that the interior finishing material attached to the surface has cracks. No more.

Moreover, the adhesive 72 has a vibration-damping effect due to the function of a vibration-proof rubber, and even if a displacement occurs between the inner wall panel 5 and the ceiling panel 6, the adhesive 72 buffers the displacement and reduces vibration. Further, since only the use of the adhesive 72 is used, a great effect can be obtained as compared with the influence on the volume and workability, and it is an inexpensive construction method. This is due to the joint, and the effect on the structure of the building can be suppressed.

The surrounding edge 7 and the inner wall panel 5, the surrounding edge 7
Adhering the ceiling panel 6 and the ceiling panel 6 sufficiently is also effective in improving the airtightness and sound insulation at that portion. FIG. 2 is a perspective view showing a mounting structure of the outer wall panel.

The vibration of the building is attenuated by the elastic deformation of the frame steel frame 20 accompanying the displacement of the outer wall panel 30.

Thus, a vibration damping device having the outer wall panel 30 as an absorber weight and the frame steel frame 20 as a spring is constituted, and the outer wall panel 3 is adapted to the natural period of the vibration of the building.
0 is displaced. When the building vibrates greatly, the outer wall panel 30 is greatly displaced accordingly, and the frame steel frame 20 supporting the outer wall panel 30 is elastically deformed, whereby the vibration energy is absorbed by the elastic deformation, and a separate vibration damping device is used. Building vibration is damped without need.

Reference numeral 00 denotes a rigid frame structure composed of beams 101 and columns 102, and forms a building frame (structure) that flexibly responds by being deformed by wind and other external forces. The outer wall panel 110 includes fasteners 120 such as bolts and rivets.
Frame frame 1 in a manner not completely restrained
00 is displaceably mounted. Exterior wall panel 11
Numeral 0 has a weight corresponding to the absorber weight, and vibrates relative to the skeleton steel frame 100 in response to the natural period of the vibration of the building. The outer wall panel 110 is manufactured separately in a factory or the like, and is a panel to which the frame steel frame 100 is attached on site.

A joint material 130 is disposed between the frame steel frame 100 and the outer wall 110.

0 is poured. The adhesive 140 sufficiently adheres to both the skeleton steel frame 100 and the outer wall 110 by curing,
It functions as a vibration absorbing member between the skeleton steel frame 100 and the outer wall 110.

According to the above configuration, when the frame steel frame 100 is vibrated by an external force, the vibration energy is transferred to the outer wall panel 110 and resonates, and is absorbed and dissipated by the internal friction due to the elastic deformation of the adhesive 140. The vibration of the building itself is reduced. When the excitation force is small, the adhesive 140 increases the rigidity of the building by the resistance to the deformation, and produces the effect of reducing the shaking by increasing the rigidity of the building. When an excessive displacement such as a large earthquake is applied, the structure is broken to avoid an influence on the structure (deformation of the steel frame 100).

The installation of the vibration absorbing member by the adhesive 140 can be of a type in which the adhesive 140 is poured after the outer wall panel 110 is attached as usual, and the construction can be simplified.

An adhesive tape 150 is sandwiched between the frame 100 and the outer wall panel 110. Accordingly, when the frame steel frame 100 is vibrated by an external force, the vibration energy is transferred to the outer wall panel 110 and resonates, and is absorbed and dissipated by the internal friction due to the elastic deformation of the adhesive tape 150, and the vibration of the building itself is reduced. Reduce.

Also in this case, the adhesive tape 150
When the excitation force is small, the rigidity of the building is increased by the resistance to deformation, and the effect of reducing the shaking by increasing the rigidity of the building is produced. In addition, when an excessive displacement such as a large earthquake is applied, it is broken to avoid an influence on the structure. In addition, since it is only necessary to attach the adhesive tape 150 to one of the attachment surfaces of the outer wall panel 110 and the skeleton steel frame 100, the construction can be simplified.
