Since the structure exhibits a behavior different from that of the building, a relative displacement occurs between the seismic isolation floor 4 and the building wall 2. Among the above relative displacements, the relative displacement in the horizontal direction that occurs between the seismic isolation floor 4 and the building wall 2 is due to the sliding between the closing plate 8 and the gap formed around the seismic isolation floor 4.

えなかつた。[Problems that the invention aims to solve] However, earthquakes are not limited to horizontal shaking, but can also be vertical shaking, or a combination of horizontal shaking and vertical shaking, and the conventional seismic isolation floor shock absorber is not effective. If the closing plate 8 is fixed to the building wall 2 so that its position cannot be changed, the relative displacement in the vertical direction that occurs between the seismic isolation floor 4 and the building wall 2 cannot be absorbed. Ta. Therefore, the vibration in the vertical direction of the building is transmitted to the seismic isolation floor 4, which also vibrates, making it unsuitable for use as a floor for installing equipment that is sensitive to vibration.
そこで、本考案は、免震床周辺部と建屋壁との

にする。 1 and 2 show an embodiment of the present invention, in which the space between the peripheral part of a seismic isolation floor 4 having the same configuration as the conventional seismic isolation floor shown in FIG. 3 and the building wall 2 is shown. A gap 3 formed in the space is closed by an extensible plate 10 hinged to a seismic isolation floor 4 and a building wall 2 so as to be rotatable in the vertical direction. That is, the expandable plate 10 that closes the gap 3 between the peripheral part of the seismic isolation floor 4 and the inner surface of the building wall 2 is made of a plate material 11,
It consists of a sheath part 12 that slidably accommodates one side of the plate material 11, and the free end side of the plate material 11 is attached to the periphery of the seismic isolation floor 4 with a hinge 13 so as to be freely rotatable in the vertical direction. In addition, the free end side of the sheath is attached to the building wall 2 at a required height position, that is, at a position where the telescopic plate 10 can be stood upright in the most shortened state, with a hinge 14 so as to be freely rotatable in the vertical direction, and the seismic isolation floor 4 and the building wall 2 can be absorbed by the expansion/contraction and tilting of the expansion/contraction plate 10.

する。 In addition, in the corner part of the room surrounded by the building wall 2, the board material 11 attached around the seismic isolation floor 4
It is necessary to connect both sides of the base isolation floor 4 and both ends of the sheath part 12 to form a series, but in this case, there are two directions of relative displacement in the horizontal direction between the seismic isolation floor 4 and the building wall 2: the front-back direction and the horizontal direction. Therefore, if the plates 11 are rigidly connected to each other at the corners, the connection will be strained when there is relative displacement in the horizontal direction, so rubber plates 15 are attached to both ends of the plates 11, and the rubber plates 15 form the corner parts. Make it. Furthermore, the connections at the corner portions between the sheath portions 12 are not made rigid to prevent strain on the connection portions during relative displacement in the horizontal direction.

ある。 The surrounding area of the seismic isolation floor 4 and the building wall 2 are usually
As shown by the solid line in the figure, there is a certain gap 3.

より吸収できる。 In the above state, when an earthquake occurs and lateral shaking occurs, the seismic isolation floor 4 and the building wall 2 behave differently in the horizontal direction, and there is a gap between the peripheral part of the seismic isolation floor 4 and the building wall 2. causes a relative displacement in the horizontal direction. In this case, the relative displacement in the left-right direction (X-axis direction) can be absorbed by the expansion and contraction and tilting of the expandable plate 10 on the X-axis side, and at this time, the expandable plate 10 located in the front-rear direction (Y-axis direction) 10 can absorb displacement in the X-axis direction by horizontally sliding the plate member 11 and sheath portion 12. In addition, in the case of relative displacement in the Y-axis direction, the telescopic plate 10 located in the Y-axis direction
expansion/contraction and tilting, and expansion/contraction plate 1 on the X-axis direction side
This can be absorbed by horizontally sliding the plate material 11 and the sheath part 12.

より容易に相対変位を吸収することができる。 Furthermore, when pitching occurs due to an earthquake and a relative displacement occurs in the vertical direction between the seismic isolation floor 4 and the building wall 2, the extensible plate 10 expands and contracts in an inclined state to easily absorb the relative displacement. I can do it.

従でき、免震床４に振動を伝えることがない。 Furthermore, if a combination of pitching and lateral shaking occurs, causing relative displacement between the seismic isolation floor 4 and the building wall 2 in the horizontal and vertical directions, this is indicated by the two-dot chain line in Figure 1. If the building wall 2 is displaced upward from the normal state shown by the solid line with respect to the seismic isolation floor 4,
On the other hand, if they approach and are displaced downward, even in this case, the expansion/contraction plate 10 can follow the displacement by expansion/contraction and tilting, and vibrations will not be transmitted to the seismic isolation floor 4.

However, plate material 11
may be attached to the building wall 2, and the sheath 12 may be attached around the seismic isolation floor 4.Also, although the sheath 12 of the extensible plate 10 is shown as an integrated body in the lateral direction, It may be divided into a plurality of parts to form a split type.Furthermore, in order to improve the slidability between the plate material 11 of the telescopic plate 10 and the sheath portion 12, a ball or the like may be rotatably inserted between the two. .
