収する装置を設置するものの３通りである。 In other words, there are devices that simply put anti-vibration rubber or roller bearings under the floor assembly, free-access floor types that install pillars with anti-vibration rubber etc. between the floor assembly and slabs, and devices that absorb horizontal vibrations. There are three ways to install the .
しかしながら以上の方法はいずれも床の面内剛
性を高め、水平方向の防振に機能するに過ぎず、
耐震性能としての減衰性能、特に鉛直方向にも有
効な減衰性能までをも発揮するものではない。 However, all of the above methods only work to increase the in-plane rigidity of the floor and provide vibration isolation in the horizontal direction.
It does not exhibit damping performance as earthquake resistance, especially effective damping performance in the vertical direction.

衰させる、粘性減衰性能を発揮するものである。 A viscous damping device is fixed to a slab, and is fixed to a rising wall that will rise from this, and a hanging wall that is fixed to a floor assembly and hangs down from there. It is constructed by filling a viscous material or a viscoelastic material, and this viscous material, etc. It exhibits viscous damping performance, which dampens vibrations in the horizontal and vertical directions through the viscous resistance of the material.

とともに床荷重を負担する。 As shown in Fig. 2, the support member 3 is made up of pillars 3a and anti-vibration rubber 3, similar to the conventional free access floor type.
b, or consists of roller bearings,
A viscous damping device 4 is arranged between the slab 1 and the floor assembly 2, for example under the nodes of the grid of the floor assembly 2 as shown in FIG.
It also bears the floor load.
