It is described that the ball bearing is formed on the inner surface of an upper plate portion of the C-shaped steel, and a mechanism for adjusting the mounting height of the ball bearing is provided.
これに対し、本発明の免震フリーアクセスフロアは、以下のように構成されている。  On the other hand, the seismic isolation free access floor of the present invention is configured as follows.
建造物のコンクリート床スラブ上に複数の支柱を一定の配置にて立設し、該支柱の先端に球体保持部を有し、該複数の球体保持部において回転自在に保持された球体を介してフロアパネルに積層された薄鋼板を支持することを特徴とし、建造物のコンクリート床スラブ上に配置された複数の支柱のうち、防振材を介して形成された支柱が含まれていることを特徴とし、地震時にフロアパネルが球体上をスライドするとき、防振材を介して形成された支柱のスライド抵抗が大きく、防振材を介して形成された支柱が首振り状態になり、フロアパネルに積層された薄鋼板より離脱して、フロアパネルの全重量が防振材を介していない他の支柱に付加されるように構成したことを特徴とし、且つ、フロアパネルの全重量が防振材を介していない全支柱に付加される場合、地震時には、フロアパネルが水平全方向にスライドしても、球体が回転するのでスライド抵抗が小さく、十分な免震効果を得ることができるように構成した免震フリーアクセスフロアを提供する。  A plurality of pillars are erected on a concrete floor slab of a building in a fixed arrangement, and a sphere holding part is provided at a tip of the pillar, and a sphere held rotatably in the plurality of sphere holding parts is provided. It is characterized by supporting thin steel sheets laminated on floor panels, and among a plurality of pillars arranged on a concrete floor slab of a building, a pillar formed via a vibration isolator is included. The feature is that when the floor panel slides on a sphere during an earthquake, the sliding resistance of the strut formed through the vibration isolating material is large, the strut formed through the vibration isolating material swings, and the floor panel Characterized in that the entire weight of the floor panel is separated from the thin steel sheet laminated on the other, so that the entire weight of the floor panel is added to another support not via the vibration isolating material. All branches not through wood When the earthquake occurs, even if the floor panel slides in all directions horizontally, the sphere rotates, so the slide resistance is small and the seismic isolation free access floor is configured to obtain a sufficient seismic isolation effect. I will provide a.
フロアパネルに積層された下向凹状鋼板は、フロアパネルの隣接ジョイント補強と撓み防止の効力を有している。  The downward concave steel plate laminated on the floor panel has the effect of reinforcing the adjacent joint of the floor panel and preventing bending.
また、建造物のコンクリート床スラブ上に複数の支柱を一定の配置にて立設し、該支柱の先端に球体保持部を有し、該複数の球体保持部において回転自在に保持された球体を介してフロアパネルに積層された下向凹状薄鋼板を支持し、球体の移動量が復元可能に構成したことを特徴とし、コンクリート床スラブ上に立設された支柱の基部がベースプレートに溶接されており、先端部は支持プレートを介して球体保持部が固定され、該球体保持部に回転自在に保持された球体は球体保持部内の摩擦材に制動されながら下向凹状薄鋼板を支持し、該下向凹状薄鋼板の端部で球体の移動が休止した後、復元方向へ移動することを特徴とし、支柱には設置時の高さ調節用の長ナットとロックナットが具備されていることを特徴とする免震フリーアクセスフロアを提供する。  Also, a plurality of pillars are erected in a fixed arrangement on a concrete floor slab of a building, a sphere holding part is provided at a tip of the pillar, and a sphere held rotatably in the plurality of sphere holding parts is provided. It is characterized by a structure in which the downwardly concave thin steel plate laminated on the floor panel is supported and the amount of movement of the sphere can be restored, and the base of the column erected on the concrete floor slab is welded to the base plate The sphere holding part is fixed at the tip part via a support plate, and the sphere rotatably held by the sphere holding part supports the downward concave thin steel sheet while being braked by the friction material in the sphere holding part, After the movement of the sphere is stopped at the end of the downward concave thin steel plate, the sphere moves in the restoring direction, and the support column is provided with a long nut and a lock nut for height adjustment at the time of installation. Characteristic seismic isolation free access To provide a floor.
図2に示すように、防振材43を介して立設された支柱40は、防振材43の材質が合成ゴム等の弾力性材質で構成され、球体4をフロアパネル1の下面に積層された薄鋼板2へ押圧しているので、防振材を使用していない他の支柱30,50に比べて、フロアパネル1の水平スライドの抵抗が大きい。  As shown in FIG. 2, the support 40 erected through the vibration isolator 43 is made of a resilient material such as synthetic rubber, and the sphere 4 is laminated on the lower surface of the floor panel 1. Since the pressure is applied to the thin steel plate 2, the floor panel 1 has a greater horizontal sliding resistance than the other columns 30 and 50 that do not use the vibration isolator.
その結果、フロアパネル1がスライドする場合、防振材43を介して形成された支柱40が図2に示すように首振り状態になり、フロアパネル1に積層された薄鋼板2より離脱して、フロアパネル1の全重量が防振材を介していない他の支柱30及び支柱50に付加され、球体3及び球体5が回転するので、スライド抵抗は小さく、フロアパネル1が球体3及び球体5の上を水平全方向にスライド可能になり免震効果を得ることができる。  As a result, when the floor panel 1 slides, the strut 40 formed via the vibration isolator 43 is swung as shown in FIG. 2 and detaches from the thin steel plate 2 laminated on the floor panel 1. Since the entire weight of the floor panel 1 is added to the other support 30 and the support 50 not via the vibration isolating material, and the spheres 3 and 5 rotate, the slide resistance is small, and the floor panel 1 is connected to the spheres 3 and 5. Can be slid horizontally in all directions, and a seismic isolation effect can be obtained.

本発明は、図1に示すように、基本的に建造物のコンクリート床スラブ6上に複数の支柱30、40、50を一定の配置にて立設し、該支柱の先端に球体保持部31、41、51を有し、該複数の球体保持部31、41、51において回転自在に保持された球体3、4、5を介してフロアパネル1に積層された薄鋼板2を支持する構造が基本である。  In the present invention, as shown in FIG. 1, a plurality of columns 30, 40, 50 are basically erected in a fixed arrangement on a concrete floor slab 6 of a building, and a sphere holding portion 31 is provided at the tip of the column. , 41, 51, and supports the thin steel plate 2 laminated on the floor panel 1 via the spheres 3, 4, 5 rotatably held by the plurality of sphere holding portions 31, 41, 51. Basic.
フロアパネル1に積層された薄鋼板2が水平スライドする時、図2に示すように、自重による摩擦抵抗の影響を受けて支柱40が首振り状態となり、球体4はフロアパネル1に積層された鋼板2より離脱する。  When the thin steel plate 2 laminated on the floor panel 1 slides horizontally, as shown in FIG. 2, the column 40 is swung under the influence of the frictional resistance due to its own weight, and the sphere 4 is laminated on the floor panel 1. Separates from steel plate 2.
その結果、フロアパネル1及び薄鋼板2の全重量が防振材を介していない他の支柱30及び支柱50に付加される。As a result, the entire weight of the floor panel 1 and the thin steel plate 2 is added to the other columns 30 and columns 50 that do not interpose the vibration isolator.
球体3及び球体5が回転するので、スライド抵抗は小さく、フロアパネル1が球体3及び球体5の上を水平全方向にスライド可能になり免震効果を得ることができる。  Since the sphere 3 and the sphere 5 rotate, the slide resistance is small, and the floor panel 1 can slide on the sphere 3 and the sphere 5 in all horizontal directions, so that a seismic isolation effect can be obtained.
また、他の実施例として図3乃至図4に示すように、建造物のコンクリート床スラブ6上に複数の支柱60,60・・・を一定の配置にて立設し、該支柱の先端に球体保持部61を有し、該複数の球体保持部61において回転自在に保持された球体7を介してフロアパネル1に積層された下向凹状薄鋼板200を支持し、球体7の移動が下向凹状薄鋼板200の端部に達した後、反動で元の位置に復元可能に構成されている。  As another embodiment, as shown in FIGS. 3 and 4, a plurality of columns 60, 60... Are erected in a fixed arrangement on a concrete floor slab 6 of a building, and It has a sphere holding part 61, and supports the downward concave thin steel sheet 200 laminated on the floor panel 1 via the spheres 7 rotatably held in the plurality of sphere holding parts 61, so that the movement of the sphere 7 is lower. After reaching the end of the concavo-convex thin steel plate 200, it is configured to be able to return to its original position by reaction.
したがって、球体7の移動範囲は他の球体に比べて広いので、地震の長周期の揺れに対応することができ、フロアパネル1が他の球体の上を水平全方向にスライド可能になるので、短周期の場合の免震効果を得ることができる。  Therefore, since the moving range of the sphere 7 is wider than the other spheres, it is possible to cope with the long-period shaking of the earthquake, and the floor panel 1 can slide on the other spheres in all horizontal directions. The seismic isolation effect in the case of a short cycle can be obtained.
コンクリート床スラブ6上に立設された複数の支柱60の基部がベースプレート66の溶接部67に溶接されており、先端部は支持プレート62を介して球体保持部61が固定され、該球体保持部61に回転自在に保持された球体7は球体保持部61内の摩擦材63に制動されながら下向凹状薄鋼板200を支持し、該下向凹状薄鋼板200の端部で球体71の移動が休止した後、復元方向へ移動する。  The bases of the plurality of columns 60 erected on the concrete floor slab 6 are welded to the welded portion 67 of the base plate 66, and the tip is fixed to the sphere holding portion 61 via the support plate 62, The sphere 7 rotatably held by 61 supports the downward concave thin steel plate 200 while being braked by the friction material 63 in the sphere holding portion 61, and the movement of the sphere 71 at the end of the downward concave thin steel plate 200. After pausing, move in the restoration direction.
支柱60には設置時の高さ調節用の長ナット64とロックナット65が具備されているので、フロアパネル1とコンクリート床スラブ6との空間部に合わせて高さ調節が可能に構成されている。  Since the support column 60 is provided with the long nut 64 and the lock nut 65 for height adjustment at the time of installation, the height can be adjusted according to the space between the floor panel 1 and the concrete floor slab 6. I have.
