Field of the Invention
The present invention relates to a base isolation floor structure that is used, for example, as a floor structure, such as a free access floor, and operates a base isolation function against vibration and displacement of a building on earthquake or the like.
Description of the Conventional Art
Examples of the ordinary base isolation floor structure include a base isolation floor structure 2 shown in
The ordinary base isolation floor structure 2 contains plural horizontally moving structures 4 (i.e., base isolation structure) that are provided horizontally movably on the floor surface 5a of the sole plates 5, and thereby vibration and displacement in the horizontal direction of the building caused by earthquake or the like are prevented from being transmitted directly to a floor board 6 fixed on the horizontally moving structures 4 and a free access floor or the like, which is not shown in the figure, disposed on the floor board 6.
The horizontally moving structure 4 of the ordinary base isolation floor structure 2 has a space S having an annular horizontal cross sectional shape between a convex spherical surface 10a of an inner member 10 and a concave spherical surface 12a of an outer member 12. The horizontally moving structure 4 is provided horizontally movably with respect to the floor surface 5a of the sole plates 5 through guidance of plural balls 8 (i.e., rolling members) disposed between the floor surface 5a and a bottom surface 10b of the inner member 10 and inside the space S.
An upper surface 12b of the horizontally moving structure 4 has the floor board 6 in the form of a flat plate placed thereon. The floor board 6 is fixed to the outer member 12 through screw engagement of an external thread of a bolt 14 and an internal thread 12c of the outer member 12. An upper surface 6a of the floor board 6 has an free access floor, which is not shown in the figure, placed thereon and fixed thereto.
In the ordinary base isolation floor structure 2, the floor board 6 can move freely in any direction within the approximately horizontal surface on the floor surface 5a through horizontal movement of the plural horizontally moving structures 4 fixed to the floor board 6 with respect to the floor surface 5a of the sole plates 5.
JP-A-2000-266115
However, the ordinary base isolation floor structure 2 does not have such a structure that the balls 8 are retained by the horizontally moving structure 4 or the like, and thus has such a problem that in the case where a foundation floor surface 3 has a portion having unevenness (i.e., inclination and roughness that impair the flatness) formed thereon, the floor surface 5a of the sole plates 5 also has unevenness formed thereon, and between the floor surface 5a and the bottom surface 10b of the inner member 10, a part of the balls 8 of the horizontally moving structure 4 are released off from the bottom surface 10b of the inner member 10, thereby deteriorating the base isolation performance.
In the ordinary base isolation floor structure 2, furthermore, in the case where the floor board 6 are floated up due to vibration and displacement of a building caused by earthquake or the like, there is such a problem that the horizontally moving structures 4 fixed to the floor board 6 are also floated up simultaneously, and also in this case, a large number of the balls 8 are released and scattered off from the bottom surface 10b of the inner member 10, thereby deteriorating the base isolation performance.
As measures for solving the problems, it may be considered that a smooth surface without unevenness is formed on the foundation floor surface 3, the sole plate 5 having a large thickness is used, and the weight of the floor board 6, the free access floor or the like is increased to prevent the horizontally moving structures 4 from being floated up, but these measures have a problem of large amounts of labor and cost.
An object of the invention is to provide such a base isolation floor structure that even when the floor surface has a portion having unevenness formed thereon, or when the base isolation frame is floated up due to earthquake or the like, the base isolation floor structure is prevented from suffering deterioration of the base isolation performance thereof caused by releasing the rolling members off from a part of the base isolation structure.

even when the floor surface has a portion having unevenness formed thereon, or when the base isolation frame is floated up due to earthquake or the like, the base isolation floor structure is prevented from suffering deterioration of the base isolation performance thereof caused by releasing the rolling members off from a part of the base isolation structure.

Embodiments for carrying out the base isolation floor structure according to the invention will be described specifically with reference to the drawings.
A base isolation floor structure 40 of this embodiment has a base isolation frame 42 having frames 46 and 48 and a joint member 50, and the base isolation frame 42 is supported from below with plural base isolation bearings 44.
In the base isolation frame 42, the frames 46 and 48, each of which is formed of an H-section steel, are disposed in such a manner that the longitudinal directions thereof intersect with each other approximately perpendicularly in the horizontal plane, and plural frames 46 and 48 are combined and disposed in the form of a lattice as viewed from the above.
The frames 46 and 48 are connected at the adjacent parts thereof through a joint member 50 and are fixed to each other.
Specifically, the plate-like portion at the cross sectional center of the H-section of the frame 48 is superimposed on one of the plate-like portions of the joint member 50 in the form of a plate having been bent at 90°, and is fixed to the joint member 50 through screw engagement of an external thread of a bolt 51 penetrating through the through holes formed in the plate-like portions and an internal thread of a nut 53. The frame 46 is also fixed to the other plate-like portion of the joint member 50 in the same manner.
A supporting leg 49 of a free access floor is placed on the upper flange of the frame 46 as in
A base isolation bearing 44 under the frames 46 and 48 has a mounting member 52, a connecting member 54, a bolt 56 (i.e., a rod member), a coil spring 58, a horizontally moving structure 60 (i.e., a base isolation structure), a plate member 62 and cushion rubber 64 (i.e., an elastic plate member), and the base isolation bearing 44 is disposed on a floor surface 43a of plural sole plates 43 in the form of a thin plate laid on a foundation floor surface.
The mounting member 52 of the base isolation bearing 44 has a flat plate portion 52a having a approximately square plate shape and a cylinder portion 52b having a hexagonal outer shape protruding downward from the center of the flat plate portion 52a, and the cylinder portion 52b has an internal thread 52c on the inner circumferential portion thereof (see
The flat plate portion 52a of the mounting member 52 is in contact with the lower flange of the frame 46 as in
The connecting member 54 of the base isolation bearing 44 has a flat plate portion 54a having a approximately square shape and a protruding portion 54b protruding upward from the center of the flat plate portion 54a as shown in
As shown in
The mounting member 52 and the connecting member 54 are fixed to each other non-relatively rotatably by screwing an external thread of a locking screw 66 into an internal screw hole, which is not shown in the figure, formed on the lower end of the mounting member 52.
The flat plate portion 54a of the connecting member 54 has at the four corners thereof through holes 54c, through each of which an intermediate portion in the longitudinal direction of an external thread 56a of the bolt 56 penetrates with an allowance.
The plate member 62 of the base isolation bearing 44 has the same shape as the flat plate portion 54a of the connecting member 54 as shown in
The plate member 62 is placed on an upper surface 74c of an outer member 74 of the horizontally moving structure 60. Four coil springs 58 and cushion rubber 64 are placed on the plate member 62.
The cushion rubber 64 of the base isolation bearing 44 is formed in a approximately square plate shape as shown in
The cushion rubber 64 is shown in the figures other than
Specifically, the cushion rubber 64 has, as shown in
The cushion rubber 64 has plural grooves 64e that are recessed in a squared U-shape from a bottom surface 64c thereof, extend in one edge that is in parallel to the horizontal direction as in
The cushion rubber 64 can be deflected and can decrease the thickness dimension thereof on application of pressure.
The cushion rubber 64 is held between the flat plate portion 54a of the connecting member 54 and the plate member 62 as shown in
The four bolts 56 shown in
The four bolts 56 are fixed to the horizontally moving structure 60 through screw engagement of tip ends of the external threads 56a thereof that protrude downward from the plate member 62 with internal threads 74f (see
The horizontally moving structure 60 of the base isolation bearing 44 shown in
The inner member 72 is formed in a disk shape having a convex spherical surface 72a on the outer circumference cross section and has a cylinder portion 72b that protrudes upward from the center of the upper side of the inner member 72 and is integrated therewith. An upper surface 72c of the cylinder member 72b has four internal threads 72e opened thereon.
The outer member 74 is formed in a approximately cylindrical shape having a small height, and has on the inner cross sectional surface thereof a concave spherical surface 74a corresponding to the convex spherical surface 72a of the inner member 72. The outer member 74 has on the bottom surface thereof an opening 74g opened on the concave spherical surface 74a, and has above the opening 74g a recessed portion 74b recessed upward from the surrounding as in
The outer member 74 has in the center portion on the upper surface 74c thereof four dish-shaped holes 74e penetrating through the upper surface 74c to the ceiling surface of the recessed portion 74b.
The outer member 74 is fixed to the inner member 72 in such a manner that the cylinder portion 72b of the inner member 72 is inserted into the recessed portion 74b of the outer member 74, external threads 76a of countersunk screws 76 are inserted into the dish-shaped holes 74e of the outer member 74, and the tip ends of the external threads 76a are screwed in and engaged with the internal threads 72e of the inner member 72.
As shown in
The balls 70 are disposed adjacent to each other along the center lines of the space S and a space between the bottom surface 72d of the inner member 72 and the floor surface 43a of the sole plate 43.
The balls 70 are disposed between the bottom surface 72d of the inner member 72 and the floor surface 43a of the sole plate 43, and thereby the bottom surface 74d of the outer member 74 is disposed slightly above away from the floor surface 43a to prevent the bottom surface 74d from being in contact with the floor surface 43a.
When the horizontally moving structure 60 moves horizontally on the floor surface 43a of the sole plate 43, under the bottom surface 72d of the inner member 72, the balls 70 that are positioned on the opposite side of the moving direction of the horizontal movement enter into the space S and move circularly, and the balls 70 that are positioned on the side of the moving direction of the horizontal movement move toward the opposite side to the moving direction of the horizontal movement of the horizontally moving structure 60.
When the horizontally moving structure 60 moves horizontally, accordingly, the balls 70 move horizontally or move circularly by following the horizontal movement, and the base isolation frame 42 can move freely in any horizontal direction on the floor surface 43a of the sole plate 43 according to such an operation of the horizontally moving structure 60 guided by the balls 70.
The base isolation bearing 44 on setting up is adjusted to such a height that the connecting member 54 and the cushion rubber 64 are in contact with each other, and the cushion rubber 64 and the plate member 62 are in contact with each other, as shown in
The external thread 56a of the bolt 56 is inserted loosely with an allowance into the through hole 54c of the flat plate portion 54a of the connecting member 54, the interior of the coil spring 58 and the through hole 62a of the plate member 62, but does not fix them.
Accordingly, the axial line of the external thread 56a of the bolt 56 can be inclined to a prescribed angle with respect to the axial line of the through hole 54c. According to the procedure, the horizontally moving structure 60 is allowed to rotate to a prescribed angle with respect to the flat plate portion 54a of the connecting member 54.
As shown in
In this case, in the left half as in
In the base isolation floor structure 40 according to this embodiment, the relative angle of the horizontally moving structure 60 with respect to the flat plate portion 54a of the connecting member 54 can be changed to a certain extent corresponding to unevenness (i.e., inclination and roughness that impair the flatness) of the foundation floor surface 41 or the floor surface 43a of the sole plate 43, and therefore even when unevenness is formed on the foundation floor surface 41 or the floor surface 43a of the sole plate 43, the balls 70 positioned between the bottom surface 72d of the inner member 72 of the horizontally moving structure 60 and the floor surface 43a of the sole plate 43 can all be made in contact with the floor surface 43a.
The length dimension between the lower surface of the head portion of the bolt 56 and the upper surface 74c of the outer member 74 of the horizontally moving structure 60 is larger than the total thickness dimension of the flat plate portion 54a of the connecting member 54, the plate member 62 and the cushion rubber 64, and thereby the horizontally moving structure 60 supports from below the flat plate portion 54a of the connecting member 54 through the plate member 62 and the cushion rubber 64 or is separated downward therefrom, corresponding to the change of the distance between the lower surface of the flat plate portion 54a of the connecting member 54 and the floor surface 43a of the sole plate 43.
Specifically, in the case where the distance between the floor surface 43a of the sole plate 43 and the flat plate portion 54a of the connecting member 54 is small, and the lower surface of the head portion of the bolt 56 and the flat plate portion 54a of the connecting member 54 are separated from each other certainly largely as shown in
In the case where the distance between the floor surface 43a of the sole plate 43 and the flat plate portion 54a of the connecting member 54 is larger than the distance in
Accordingly, the bolt 56 has such a length that when the tip end of the external thread 56a thereof is screwed in and engaged with the internal thread 74c of the horizontally moving structure 60 in the normal state, the lower surface of the head portion thereof faces the upper surface of the flat plate portion 54a of the connecting member 54 with a certainly large distance, but in the case where the horizontally moving structure 60 descends largely due to unevenness of the foundation floor surface 41 or the floor surface 43a of the sole plate 43, there is an increased possibility of contact of the lower surface of the head portion of the bolt 56 with the upper surface of the flat plate portion 54a of the connecting portion 54, and the horizontally moving structure 60 and the flat plate portion 54a of the connecting member 54 are close to the most separated state.
Thus, in the case where unevenness is formed on the foundation floor surface 41 or the floor surface 43a of the sole plate 43, on which one base isolation bearing 44 among the plural base isolation bearings 44 supporting the base isolation frame 42 is placed, and the height position of the floor surface 43a is lower than the floor surface 43a having the other base isolation bearings 44 placed thereon, the horizontally moving structure 60 descends downward by increasing the distance from the lower surface of the flat plate portion 54a of the connecting member 54, thereby making the balls 70 in contact with the floor surface 43a, as shown in
In the case where base isolation frame 42 is floated up due to earthquake or the like, the horizontally moving structure 60 descends downward by increasing the distance from the lower surface of the flat plate portion 54a of the connecting member 54, thereby making the balls 70 in contact with the foundation floor surface 41.
In the case where the distance between the floor surface 43a and the flat plate portion 54a of the connecting member 54 is increased due to unevenness of the foundation floor surface 41 or the floor surface 43a of the sole plate 43, the horizontally moving structure 60 descends by the own weight thereof, thereby maintaining the contact state with the floor surface 43a as shown in
As shown in
In the base isolation floor structure 40 according to this embodiment, the vertical distance between the flat plate 54a of the connecting member 54 and the horizontally moving structure 60 can be changed corresponding to the change of the height of the foundation floor surface 41 or the floor surface 43a of the sole plate 43 or the float-up of the base isolation frame 42 due to earthquake or the like, and thereby the balls 70 of the horizontally moving structure 60 can all be made in contact with the floor surface 43a of the sole plate 43 even when the floor surface 43a has a portion that has a height different from the other most portions, or the base isolation frame 42 is floated up.
In the base isolation floor structure 40 according to this embodiment, the base isolation bearing 44 is constituted by the mounting member 52, the connecting member 54, the supporting rod member 56 and the horizontally moving structure 60 to provide a simple structure for the base isolation bearing 44, and thus the material cost and the production cost thereof can be reduced.
In the base isolation floor structure 40 according to this embodiment, it is not necessary that the foundation floor surface 41 is formed as a smooth surface without unevenness, the thickness of the sole plate 43 is increased, or the weight of the base isolation frame 42, the free access floor or the like supported by the base isolation bearing 44 is increased, and thereby the material cost and the production cost of the base isolation floor structure 40 can be reduced.
According to the base isolation floor structure 40 according to this embodiment, as described above, even when the floor surface 43a has a portion having unevenness formed thereon, or the base isolation frame 42 is floated up due to earthquake or the like, the balls 70 can be prevented from being released off from a part of the horizontally moving structure 60, thereby preventing the base isolation performance from being deteriorated.
The base isolation floor structure 80 according to this embodiment is different from the base isolation floor structure 40 according to the first embodiment in the point shown in
As shown in

The connecting member 84 has a convex spherical surface portion 84f at the tip end of the downward protruding portion 84e. The convex spherical surface portion 84f is in contact with the center of the upper surface 74c of the outer member 74 of the horizontally moving structure 60.
As shown in
Accordingly, the horizontally moving structure 60 is allowed to rotate to a prescribed angle with respect to the flat plate portion 84a of the connecting member 84.
As shown in
In this case, the horizontally moving structure 60 is rotated with the part where the convex spherical surface portion 84f of the downward protruding portion 84e of the connecting member 84 is in contact therewith as the supporting point.
The length dimension between the lower surface of the head portion of the bolt 56 and the upper surface 74c of the outer member 74 of the horizontally moving structure 60 is larger than the total of the thickness dimension of the flat plate portion 84a of the connecting member 84 and the height dimension of the downward protruding portion 84e, and thereby the horizontally moving structure 60 of the base isolation bearing 82 supports from below the flat plate portion 84a of the connecting member 84, or the flat plate portion 84a of the connecting member 84 is separated from the upper surface 74c of the outer member 74 of the horizontally moving structure 60, corresponding to the change of the distance between the lower surface of the flat plate portion 84a of the connecting member 84 and the floor surface 43a of the sole plate 43.

The base isolation floor structure 100 according to this embodiment is different from the base isolation floor structure 80 according to the second embodiment in the point shown in

As shown in
The plate member 108 of the base isolation bearing 102 is formed in a approximately square plate shape as shown in
The plate member 108 has on the lower surface thereof the second round rod member 110, and is integrated with the second round rod member 110 through welding between the lower surface and the outer circumferential surface of the second round rod member 110.
As shown in
As shown in
The second round rod member 110 is disposed on the upper surface 74c of the outer member 74 of the horizontally moving structure 60, and the outer circumferential surface thereof is in contact with the upper surface 74c of the outer member 74 rotatably within a limited angle range.
As shown in
Accordingly, the horizontally moving structure 60 is allowed to rotate to a prescribed angle with respect to the flat plate portion 104a of the connecting member 104.
As shown in
In this case, the horizontally moving structure 60 is rotated with the part where the outer circumferential surface of the second round rod member 110 is in contact therewith as the supporting point.
In the case where the floor surface 43a of the sole plate 43 is inclined in the anteroposterior direction as in
In this case, the horizontally moving structure 60 is rotated with the part where the outer circumferential surface of the first round rod member 106 is in contact with the upper surface of the plate member 108 as the supporting point.
The length dimension between the lower surface of the head portion of the bolt 56 and the upper surface 74c of the outer member 74 is larger than the total of the thickness dimension of the flat plate portion 104a of the connecting member 104 and the plate member 108 and the diameter dimension of the first round rod member 106 and the second round rod member 110, and thereby the horizontally moving structure 60 supports from below the flat plate portion 104a of the connecting member 104, or the flat plate portion 104a of the connecting member 104 is separated from the upper surface 74c of the outer member 74, corresponding to the change of the distance between the lower surface of the flat plate portion 104a of the connecting member 104 and the floor surface 43a of the sole plate 43.
The base isolation floor structure 100 according to this embodiment provides the same advantageous effects as in the base isolation floor structure 40 according to the first embodiment.
The base isolation floor structure 120 according to this embodiment is different from the base isolation floor structure 40 according to the first embodiment in the point shown in
