Abstract

PROBLEM TO BE SOLVED: Conventionally, an earthquake-resistant structure of a building has braces attached to the frontage in a brace shape, and the building becomes rigid on the contrary, and the reaction such as indoor scattering and damage increases. According to the present invention, an elliptical or circular elastic body is attached to the frontage. As a result, in the event of an earthquake, the shaking can be absorbed gently, and damage to the building can be minimized. Accordingly, since the room can be accommodated by gentle shaking, damage such as scattering and breakage in the room can be reduced. [Selection] Figure 1

Description

  It relates to a cushioning earthquake-resistant structure of a building that reduces damage to the building and the room during an earthquake.

  Conventionally, since the seismic structure of a building has braces attached to the frontage in a brace shape, the building becomes rigid on the contrary, and the reaction such as indoor scattering and breakage increases.

  The present invention protects a building with an elastic body so that damage is minimized and indoor damage is also minimized.

And FIG. 1 of the problem-solving means of the present invention is that a frame is attached around the opening of a building, and an elliptical elastic body having a slightly smaller diameter than the frame is formed by a flat steel spring or the like, and is provided at four places on the circumference. A bolt-through hole is formed, a U-shaped fixture is formed, a long hole having a lower portion opened downward from the center of the bottom is formed, and a taper liner that overlaps the bottom of the fixture is formed. Open the same long hole as the fixture, then temporarily tighten the elastic body to the frame with bolts and nuts, insert the fixture into the bolt visible from the gap between the frame and the elastic body, then taper liner After that, the bolts and nuts are tightened to integrate the frame and the elastic body.
FIG. 2 shows a circular elastic body combined with an elliptical elastic body and a brace. FIG. 3 is implemented in a house, and an elliptical elastic body may be attached instead of a circular shape. FIG. 9 shows a case where it is applied to a large building such as a factory or a supermarket, and a brace is used in combination with a circular elastic body.

In FIG. 1 of the problem solving means, since the elliptical elastic body is attached to the building, the vibration can be absorbed gently and the damage can be minimized during an earthquake.
Therefore, since the room is gently shaken and stored, damage such as scattering and breakage in the room can be reduced. This structure is graceful in appearance.
In FIG. 2, since the elliptical elastic body and the brace are used in combination with the circular elastic body, the respective characteristics are combined and effectively act, and the damage of the earthquake can be minimized.
Since FIG. 3 is attached to a house, the damage can be minimized, and it is also resistant to subtle shaking caused by strong winds, so that the life of the house can be extended.
In FIG. 9, since a circular elastic body and a brace are used in combination in a large building such as a factory or a supermarket, the damage of the earthquake can be minimized by taking advantage of each characteristic.

1 of this invention is the frame attached to the frontage of a building, and is formed with steel materials, such as clean steel and I type steel. Reference numeral 2 denotes an elliptical elastic body having a slightly smaller diameter than the frame, which is formed by a flat steel spring or the like, and has bolt through holes at four places on the circumference. In addition, when a building is large or in an earthquake-prone area, a plurality of flat steel springs are stacked.
Reference numeral 5 denotes a U-shaped attachment, which has a long hole 6 with a lower portion opened downward from the center of the bottom. 7 is a taper liner, and the taper liner 7 has a long hole 6 that is the same as the attachment device 5.
Thus, the elastic body 2 is temporarily fastened to the frame 1 with a bolt nut 8, and the attachment device 5 is inserted into the bolt visible from the gap between the frame 1 and the elastic body 2, and then the taper liner 7 is driven into close contact. After that, the bolts and nuts 8 are tightened, and the frame 1 and the elastic body 2 are integrated.
In addition, in preparation for the case where the gap is not filled with the taper liner 7 alone, a flat liner without a taper is prepared, and this liner is driven first, and then the taper liner 7 is driven.
Further, since a heavy load such as shearing or tension is applied to the bolt nut 8, an elevation bolt nut is used. In addition, it is better to use a cap nut in consideration of grace.

  In FIG. 2, an elliptical elastic body 2 and a brace 4 are used in combination with a circular elastic body 3.

  In FIG. 3, a circular elastic body 3 is attached to a house.

  FIG. 9 shows a case where the present invention is applied to a large building such as a factory or a supermarket, and the brace 4 is used in combination with the circular elastic body 3.

  Although the above elastic bodies 2 and 3 were attached to the frontage, they may be attached to appropriate locations in the building. Further, in some cases, the attachment device 5 may not be used, and the attachment may be performed via the taper liner 7, or the frame 1 may not be provided and the attachment device 5 may be directly attached to a building column or beam.

Claims (1)

Attaching an opening circumferential Riniwaku buildings, also forms an oval or circular elastic body slightly smaller diameter than the frame in flat steel spring or the like, opening the bolt through holes in the periphery four points, also co-like attachment of Forming a taper liner that opens downward from the center of the bottom and forming a taper liner that overlaps the bottom of the fixture, and the taper liner has a slot that is the same as that of the fixture. Then, temporarily tighten the elastic body to the frame with bolts and nuts, insert the fixture into the bolt visible from the gap between the frame and the elastic body, then drive the taper liner into close contact, and then tighten the bolts and nuts. Cushioning seismic structure of the building which united with the elastic body.
