Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique for improving the vibration isolation of a building of a panel type curtain wall.

[0002]

2. Description of the Related Art A curtain wall is a non-bearing wall constituting an outer periphery of a building, and is attached to a building frame via a fastener. The curtain wall is required to have wind resistance, earthquake resistance, shock resistance, heat insulation, sound insulation, watertightness, airtightness, durability, and the like. Regarding the earthquake resistance, the curtain wall is locked with respect to the building frame during a large deformation of the building due to the earthquake, so that safety against falling and breakage of the curtain wall is secured.

[0003]

Since the curtain wall is made of PC concrete or the like, the curtain wall itself has sufficient rigidity.

However, in order to enable the above-mentioned locking, the curtain wall has a so-called hanging structure or the like which is attached to a fastener installed on a beam as a building frame. For this reason, despite the rigidity of the curtain wall, the rigidity is not utilized for improving the building rigidity. From the above, it can be said that the anti-vibration property at the time of minute vibration from the outside is low, and the anti-vibration property of the entire outer wall is inferior to that of the bearing wall.

The above-mentioned minute vibrations from the outside may include traffic vibrations generated from a general road, an expressway, an elevated Shinkansen, and the like. Since buildings near these traffic vibration sources are constantly affected by minute vibration, it is necessary to improve the rigidity of the building during the minute vibration. In particular, in a house, a minute vibration is received even in the early morning or at night, so that it is not possible to sleep comfortably, and there is a case where the livability is impaired. In addition, since people are less likely to feel fast shaking and easy to feel slow shaking, by increasing the rigidity of the building, by increasing the frequency of the shaking of the building for the same vibration,
This can reduce the sensation of shaking.

In view of the above problems, the inventor has devised that the rigidity of the curtain wall itself is used to improve the rigidity of the building against minute vibrations. That is, the object of the present invention is to maintain the security by the locking function of following a large deformation of a building during an earthquake, and to use the rigidity of the curtain wall itself for minute vibrations such as traffic vibrations. Is to improve. Note that the curtain wall targeted by the present invention is one in which the construction method is a panel method, and refers to a PC curtain wall, foamed concrete, or an ALC plate, and a metal curtain wall or the like in which the construction method is a cubic method. Shall not.

That is, as described in claim 1, in a vibration-damping structure of a building that forms an outer wall with a curtain wall, a vibration-damping member that bridges an adjacent curtain wall includes a curtain wall, a fixture for the curtain wall, and a fastener. It was sandwiched between.

According to a second aspect of the present invention, the vibration isolating member is constituted by a plate having a long hole to be attached to a fixture.

According to a third aspect of the present invention, the vibration isolating member comprises a pair of left-right symmetric members, and the members are connected to each other by a connecting member.

According to a fourth aspect of the present invention, there is provided an anti-vibration structure for a building in which an outer wall is constituted by a curtain wall, wherein an inner wall surface of an adjacent curtain wall is bridged by an anti-vibration member.

According to a fifth aspect of the present invention, the vibration damping member is constituted by a plate having a plurality of long holes, and is screwed to the inner wall surface of the curtain wall through the long holes.

When the building undergoes a large deformation, the stress between the curtain walls 1... Disengages the lateral wedge receivers 40 and the lateral wedges 41 so that each of the curtain walls 1. Is locked. With the above configuration, the rigidity of the whole building against minute vibrations can be improved, while being able to cope with the rocking state at the time of large deformation of the building.

As a sixth embodiment, as shown in FIG. 20, guide projections 45A and 45B are provided on stepped portions 43A and 43B of the horizontal wedge receiver 40, and a guide groove 46 is formed in the horizontal wedge 41. This eliminates displacement when driving the lateral wedge 41 and improves workability.

Further, as a seventh embodiment, as shown in FIG. 21, the screw holes 34 of the horizontal wedge receiver 40 may be formed at two locations above and below the horizontal wedge receiver 40. As an eighth embodiment, in FIG. 22, the guide projections 45A / 4
5B shows an embodiment in which 5B is configured.

The fixing wedge and the insertion wedge described in the fourth to eighth embodiments are molded products made of a hard resin or the like because they are easy to manufacture and can adjust the sliding load. It is desirable.
