Description

  The present invention relates to a seismic isolation floor coupling structure that is a structure that allows a base and a fixed floor to meet each other. In particular, the present invention relates to a seismic isolation floor coupling structure that enables smooth traffic between the seismic isolation floor and the fixed floor even in an operating state.

Seismic isolation floors that are supported by seismic isolation mechanisms are often used in rooms that store valuable items.
For example, in a room that houses a server computer, the server computer is placed on a seismic isolation floor supported by a seismic isolation mechanism.
For example, an art object is placed on a seismic isolation floor supported by a seismic isolation mechanism in a museum.
A fixed floor is placed around the seismic isolation floor.
A seismic isolation floor coupling structure is used to establish a connection between the base isolation floor and the fixed floor supported by the base isolation mechanism.
For example, the base isolation mechanism supports the base isolation floor. The seismic isolation floor assembly structure consists of a panel floor that is passed between the seismic isolation floor and the fixed floor.
For example, the part near the fixed floor of the panel floor is gently fixed.
The seismic isolation floor coupling structure transitions between a non-operating state and an operating state.
In the non-operating state, the panel floor straddles the gap between the base isolation floor and the fixed floor. A person goes back and forth between the base isolation floor and the fixed floor via the panel floor.
For example, when an earthquake occurs, the seismic isolation mechanism operates to try to suppress the displacement and acceleration of the seismic isolation floor within a predetermined range. As a result, the seismic isolation floor moves horizontally or vertically, and the gap between the seismic isolation floor and the fixed floor increases or decreases.
The edge of the panel floor on the side of the base isolation floor moves relative to the base isolation floor.
For example, the panel floor swings around a location on the fixed floor side.
A person can go back and forth between the base isolation floor and the fixed floor via the swinging panel floor.

The fixed floor side panel floor is provided so as to be adjacent to the fixed floor, and is restrained so that it can move up and down or swing so that it does not move relative to at least one or more locations close to the fixed floor in a direction approaching or separating from the fixed floor. Floor structure. The floor structure is such that the panel floor on the seismic isolation floor is adjacent to the base isolation floor. The other edge of the seismic isolation floor side panel floor far from the boundary with the seismic isolation floor is the other edge far from the boundary between the seismic isolation floor side panel floor free edge and the fixed floor side panel floor. The edge of the fixed floor side panel floor free edge is called a fixed floor side panel floor free edge, and the gap between the seismic isolation floor side panel floor free edge and the fixed floor side panel floor free edge in an inoperative state when viewed from above When a horizontal direction that appears to be extended is referred to as a gap direction and a horizontal direction that is orthogonal to the gap direction is referred to as a gap orthogonal direction, the intermediate mechanism is fixed to a foundation, and at least the gap is defined by the first intermediate mechanism. A second intermediate mechanism that is supported so that relative movement in the orthogonal direction is restricted and relative movement in the vertical direction is made free. The second intermediate mechanism is supported by the seismic isolation mechanism so as to move up and down in conjunction with the vertical movement of the seismic isolation floor and to freely move in the horizontal direction. In the non-actuated state, the seismic isolation floor side panel floor free edge and the fixed floor side panel floor free edge face each other. In the operating state, the base isolation floor side panel floor and the fixed floor side panel floor move relatively horizontally, and one of the base isolation floor side panel floor and the fixed floor side panel floor is the base isolation floor side panel. It sinks under the other of the floor and the fixed floor side panel floor.
As a result, it is possible to go back and forth between the base isolation floor and the fixed floor via the panel floor at any time in the non-operating state and the operating state.

As described above, the base isolation floor coupling structure according to the present invention has the following effects due to its configuration.
An intermediate mechanism with a sliding surface on the top is installed in the space between the base isolation floor and the fixed floor, and the panel floor on the base isolation floor is placed so as to be adjacent to the base isolation floor by loosely constraining the part close to the base isolation floor. The fixed floor side panel floor is loosely restrained at a location close to the fixed floor so as to be adjacent to the fixed floor, and the edge of the base isolation floor side panel floor and the edge of the fixed floor side panel floor are in an inoperative state. Since the upper part of the intermediate mechanism is opposed to a slight gap, the seismic isolation floor side panel floor and the fixed floor side panel floor slide on the sliding surface in the operating state so that one can sink under the other. It is possible to go back and forth between the base isolation floor and the fixed floor via the panel floor at any time in the non-operating state and the operating state.
In addition, the first intermediate mechanism fixed to the foundation supports the second intermediate mechanism having the sliding surface on the upper side so as to restrain the relative movement in the horizontal direction and make the relative movement in the vertical direction free. Since the mechanism supports the second intermediate mechanism so that the horizontal relative movement is free, the seismic isolation floor supported by the swing mechanism and the second intermediate mechanism supported by the swing mechanism are interlocked. Then, the seismic isolation floor side panel floor and the fixed floor side panel floor slide on the sliding surface of the second intermediate mechanism, and are exempted via the panel floor at any time in the non-operating state and the operating state. You can go back and forth between the seismic floor and the fixed floor.
In addition, the first intermediate mechanism fixed to the foundation supports the second intermediate mechanism having the sliding surface on the upper side so as to restrain the relative movement in the horizontal direction and make the relative movement in the vertical direction free. Since the mechanism supports the second intermediate mechanism so that the relative movement in the horizontal direction is made free and moves up and down in conjunction with the vertical movement of the base isolation floor, the base isolation floor side panel floor and the fixed floor side The panel floor slides on the sliding surface of the second intermediate mechanism that moves up and down in conjunction with the vertical movement of the seismic isolation floor. You can go back and forth between.
Further, the first intermediate mechanism fixed to the foundation restrains the movement of the second intermediate mechanism having the sliding surface on the upper part in the gap direction and the direction perpendicular to the gap direction so that the relative movement in the vertical direction is free. And the seismic isolation mechanism supports the second intermediate mechanism so that it can move in the horizontal direction and move up and down in conjunction with the vertical movement of the base isolation floor. The floor and the fixed floor side panel floor slide on the sliding surface of the second intermediate mechanism that moves up and down in conjunction with the vertical movement of the seismic isolation floor, and are exempted via the panel floor at any time in the non-operating state and the operating state. You can go back and forth between the seismic floor and the fixed floor.
In addition, the shape of the gap between the seismic isolation floor-side panel floor free edge and the fixed floor-side panel floor free edge in the non-operating state as viewed along the gap direction moves from top to bottom. The seismic isolation floor side panel floor free edge and the fixed floor side panel floor free edge slide in contact with each other when viewed in the gap direction in the operating state. One of the panel floor and the fixed floor side panel floor can stably sink under the other of the base isolation floor side panel floor and the fixed floor side panel floor.
Further, an upward inclined surface that is inclined so as to become thinner as it moves to the tip is formed on one upper side of the base-isolated floor-side panel floor free edge and the fixed floor-side panel floor free edge, A downward inclined surface that is inclined so as to become thinner as it moves to the other side, and the shape of the upward inclined surface and the shape of the downward inclined surface as viewed along the line of sight along the gap direction, Since the seismic isolation floor side panel floor free edge and the fixed floor side panel floor free edge are in contact with each other in one direction when viewed in the gap direction, the seismic isolation floor side panel slides. One of the floor and the fixed floor side panel floor can stably sink under the other of the base isolation floor side panel floor and the fixed floor side panel floor.
Further, an upward inclined surface that is inclined so as to become thinner as it moves to the tip is formed on one upper side of the base-isolated floor-side panel floor free edge and the fixed floor-side panel floor free edge, A downwardly inclined surface that is inclined so as to become thinner as it moves to the other side, and is formed between the upwardly inclined surface and the downwardly inclined surface as viewed along the line of sight in the gap direction in the operating state. A contact moves between the surface of the upward inclined surface and the surface of the downward inclined surface, and an inclination angle from a horizontal plane of at least a surface of the upward inclined surface in which the contact is moved is an angle of the downward inclined surface Since at least the inclination angle from the horizontal plane of the surface in the range in which the contact moves is larger, the seismic isolation floor-side panel floor free edge and the fixed floor-side panel floor free edge are in the gap direction in the operating state. See In Mogurikomeru contact one of the sliding said MenShinyuka side panel floor and the fixed floor side panel floor is stable under the other of the fixed bed side panel floor and the MenShinyuka side panel floor.
In addition, the first intermediate mechanism fixed to the foundation restrains the movement in the direction perpendicular to the gap direction of the second intermediate mechanism having the sliding surface on the upper part, thereby allowing the relative movement in the gap direction to be free and the relative movement in the vertical direction. Since the seismic isolation mechanism supports the second intermediate mechanism so that the relative movement in the horizontal direction is free and moves up and down in conjunction with the vertical movement of the seismic isolation floor. The seismic isolation floor panel floor and the fixed floor panel floor slide on the sliding surface of the second intermediate mechanism that moves up and down in conjunction with the vertical movement of the seismic isolation floor. You can go back and forth between the seismic isolation floor and the fixed floor.
In addition, the first intermediate mechanism fixed to the foundation restrains the movement in the direction perpendicular to the gap direction of the second intermediate mechanism having the sliding surface on the upper part, thereby allowing the relative movement in the gap direction to be free and the relative movement in the vertical direction.

I can come and go.
In addition, since the first intermediate mechanism fixed to the foundation supports the second intermediate mechanism having a sliding surface on the upper side so that the relative movement in the horizontal direction is restricted and the relative movement in the vertical direction is restricted.

Further, the first intermediate mechanism 111 fixed to the foundation G supports the second intermediate mechanism 112 having the sliding surface S on the upper side so as to restrain the relative movement in the horizontal direction and free the relative movement in the vertical direction. Since the seismic mechanism 400 supports the second intermediate mechanism 112 so as to make the relative movement in the horizontal direction free, the seismic isolation floor 300 supported by the seismic isolation mechanism 400 and the first supported by the seismic isolation mechanism 400 are used. The two intermediate mechanisms 112 move up and down in conjunction with each other, and the seismic isolation floor side panel floor 130 and the fixed floor side panel floor 120 slide on the sliding surface S of the second intermediate mechanism 112, and the non-operating state and the operating state are You can always go back and forth between the seismic isolation floor 300 and the fixed floor 200 via the panel floor.
Further, the first intermediate mechanism 111 fixed to the foundation G supports the second intermediate mechanism 112 having the sliding surface S on the upper side so as to restrain the relative movement in the horizontal direction and free the relative movement in the vertical direction. Since the seismic mechanism 400 supports the second intermediate mechanism 112 so that the relative movement in the horizontal direction is made free and moves up and down in conjunction with the vertical movement of the seismic isolation floor 300, the seismic isolation floor side panel floor 130 is fixed. The floor-side panel floor 120 slides on the sliding surface S of the second intermediate mechanism 112 that moves up and down in conjunction with the vertical movement of the seismic isolation floor 300, and is exempted via the panel floor at any time in the non-operating state and the operating state. You can move between the seismic floor 300 and the fixed floor 200.
Further, the first intermediate mechanism 111 fixed to the foundation G restrains the movement in the direction perpendicular to the gap direction P and the gap direction P to the second intermediate mechanism 112 having the sliding surface S on the upper part, and the relative movement in the vertical direction is free. Since the seismic isolation mechanism 400 supports the second intermediate mechanism 112 so that the relative movement in the horizontal direction is free and moves up and down in conjunction with the vertical movement of the seismic isolation floor. The floor-side panel floor 130 and the fixed floor-side panel floor 120 slide on the sliding surface S of the second intermediate mechanism 112 that moves up and down in conjunction with the up-and-down movement of the seismic isolation floor 300, so that the non-operating state and the operating state are always available. The seismic isolation floor 300 and the fixed floor 200 can be moved back and forth via the panel floor.
Moreover, as the shape seen along the gap direction P of the gap space at the boundary between the seismic isolation floor-side panel floor free edge 132 and the fixed floor-side panel floor free edge 122 in the non-operating state moves from top to bottom. Since it spreads, the seismic isolation floor side panel floor free edge portion 132 and the fixed floor side panel floor free edge portion 122 come into contact with each other in the gap direction P in the operating state, and the sliding seismic isolation floor side panel floor 130. One of the fixed floor side panel floor 120 and the fixed floor side panel floor 120 can stably sink under the other of the seismic isolation floor side panel floor 130 and the fixed floor side panel floor 120.
Further, an upward inclined surface S1 that is inclined so as to become thinner as it moves to the tip is formed on one upper side of the base-isolated floor-side panel floor free edge 132 and the fixed floor-side panel floor free edge 122, A downwardly inclined surface S2 that is inclined so as to become thinner as it moves toward the tip is formed on the lower side of the other, and when viewed along the gap direction P, the shape of the upwardly inclined surface S1 and the shape of the downwardly inclined surface S2 are Since they are different from each other, the seismic isolation floor side panel floor free edge 132 and the fixed floor side panel floor free edge 122 come into contact with each other in the gap direction P in the operating state and the sliding seismic isolation floor side panel floor 130 is in contact with each other. One of the fixed floor side panel floor 120 and the fixed floor side panel floor 120 can stably sink under the other of the seismic isolation floor side panel floor 130 and the fixed floor side panel floor 120.
Further, an upward inclined surface S1 that is inclined so as to become thinner as it moves to the tip is formed on one upper side of the base-isolated floor-side panel floor free edge 132 and the fixed floor-side panel floor free edge 122, A downwardly inclined surface S2 that is inclined so as to become thinner as it moves to the tip is formed on the lower side of the other, and the contact point between the upwardly inclined surface S1 and the downwardly inclined surface S2 when viewed along the gap direction P in the operating state. Moves between the surface of the upward inclined surface S1 and the surface of the downward inclined surface S2, and the inclination angle θ1 from the horizontal plane of at least the surface of the upward inclined surface S1 where the contact point moves is at least of the downward inclined surface S2. Since the inclination angle θ2 degrees from the horizontal plane of the surface where the contact moves is larger than the horizontal plane, the seismic isolation floor-side panel floor free edge 132 and the fixed floor-side panel floor free edge 122 are in the gap direction P in the operating state. See One of the sliding base isolation floor side panel floor 130 and the fixed floor side panel floor 120 can stably sink under the other of the base isolation floor side panel floor 130 and the fixed floor side panel floor 120 by contact at the contact point.
Further, the first intermediate mechanism 111 fixed to the foundation G restrains the movement of the second intermediate mechanism 112 having the sliding surface S on the upper side in the direction orthogonal to the gap direction P, and allows the relative movement in the gap direction P to be freely made up and down. And the seismic isolation mechanism 400 supports the second intermediate mechanism 112 so as to move up and down in conjunction with the vertical movement of the seismic isolation floor 300. Since the seismic isolation floor side panel floor 130 and the fixed floor side panel floor 120 slide on the sliding surface S of the second intermediate mechanism 112 that moves up and down in conjunction with the vertical movement of the seismic isolation floor 300, it does not operate. It is possible to go back and forth between the seismic isolation floor 300 and the fixed floor 200 via the panel floor at any time in the state and the operating state.
Further, the first intermediate mechanism 111 fixed to the foundation G restrains the movement of the second intermediate mechanism 112 having the sliding surface S on the upper side in the direction orthogonal to the gap direction P, and allows the relative movement in the gap direction P to be freely made up and down. The seismic isolation mechanism 400 restrains the relative movement in the gap direction P and the relative movement in the gap orthogonal direction Q freely moves up and down the seismic isolation floor 300. The second intermediate mechanism 11 in which the seismic isolation floor side panel floor 130 and the fixed floor side panel floor 120 move up and down in conjunction with the vertical movement of the base isolation floor 300 is supported. Can be moved between the seismic isolation floor 300 and the fixed floor 200 via the panel floor at any time in the non-operating state and the operating state.
Further, since the first intermediate mechanism 111 fixed to the foundation G supports the second intermediate mechanism 112 having the sliding surface S on the upper side so as to restrain the relative movement in the vertical direction, the seismic isolation floor side panel floor 130 and the fixed floor side panel floor 120 slide on the sliding surface S of the second intermediate mechanism 112 in which the vertical movement is restricted, and are fixed to the seismic isolation floor 300 via the panel floor at any time in the non-operating state and the operating state. You can go to and from the floor 200.
Further, the first intermediate mechanism 111 fixed to the foundation G supports the second intermediate mechanism 112 having the sliding surface S on the upper side so that the relative movement in the horizontal direction is restricted and the relative movement in the vertical direction is restricted. Therefore, the seismic isolation floor side panel floor 130 and the fixed floor side panel floor 120 slide on the sliding surface S of the second intermediate mechanism 112 in which the vertical movement is restricted, and always pass through the panel floor in the non-operating state and the operating state. Thus, the seismic isolation floor 300 and the fixed floor 200 can be moved back and forth.
Further, the first intermediate mechanism 111 fixed to the foundation G is constrained to move in the gap direction P by the second intermediate mechanism 112 having the sliding surface S on the upper side, and is restricted in relative movement in the gap orthogonal direction Q. The seismic isolation floor side panel floor 130 and the fixed floor side panel floor 120 slide on the sliding surface S of the second intermediate mechanism 112 in which the vertical movement is restrained and are not operated. It is possible to go back and forth between the seismic isolation floor 130 and the fixed floor 120 via the panel floor at any time in the state and the operating state.
In addition, the first intermediate mechanism 111 fixed to the foundation G has the second intermediate mechanism 112 having a sliding surface S on the upper side, and the relative movement in the gap direction P is freed and the relative movement in the gap orthogonal direction Q is restricted. Since it supported so as to restrain relative movement, the seismic isolation floor side panel floor 130 and the fixed floor side panel floor 120 slide on the sliding surface S of the second intermediate mechanism 112 whose vertical movement is restricted, The seismic isolation floor 300 and the fixed floor 200 can be moved back and forth via the panel floor at any time in the non-operating state and the operating state.
In addition, the seismic isolation floor panel floor 130 is restrained so as to be movable up and down or swingable so that it does not move relative to at least the direction away from the seismic isolation floor 300, and the fixed floor side panel floor 120 is at least fixed floor 200. Since it is restrained so that it can move up and down or swing freely so as not to move relatively in the direction of moving away from the base, the seismic isolation floor side panel floor 130 and the fixed floor side panel are interlocked with the movement of the base isolation floor 300. The floor 120 can move up and down or swing.
Further, the base isolation floor panel floor 130 is restrained so as to be movable up and down or swinging so as not to move relative to at least the direction away from the base isolation floor 300 and to move relative to the gap direction P. Since the side panel floor 120 is constrained to move up and down or swing so as not to move relative to at least the fixed floor 200 and move relative to the gap direction P, the seismic isolation floor is used. In conjunction with the movement of 300, the base isolation floor side panel floor 130 and the fixed floor side panel floor 120 can move up and down or swing.
Further, the base isolation floor side panel floor 130 is constrained so as to be movable up and down or swinging so that it does not move relative to at least the direction away from the base isolation floor 300 and is free to move relative to the gap direction P. Since the fixed floor side panel floor 120 is restrained so as to be movable up and down or swingable so as not to move relative to at least the direction away from the fixed floor 200, the fixed floor side panel floor 120 is interlocked with the movement of the seismic isolation floor 300. The seismic isolation floor panel floor 130 and the fixed floor panel floor 120 can be moved up and down or rocked.
Further, the seismic isolation floor panel floor 130 is restrained so as to be movable up and down or swingable so as not to move relative to at least the direction away from the seismic isolation floor 300, and the fixed floor panel floor 120 is at least from the fixed floor 200. Since it is restrained to move up and down or swing freely so as not to move relatively in the direction of separation and to move in the gap direction P, in conjunction with the movement of the seismic isolation floor 300, The seismic isolation floor panel floor 130 and the fixed floor panel floor 120 can move up and down or swing.
The intermediate mechanism 110 is provided in a space between the base isolation floor 300 and the fixed floor 200, the base isolation floor side panel floor 130 is provided adjacent to the base isolation floor 300, and the fixed floor side panel floor 120 is placed in the gap direction P. And is provided so as to be adjacent to the fixed floor 200 by restricting a portion close to the fixed floor 200, and in an inoperative state, the edge of the base-isolated floor-side panel floor 130 and the edge of the fixed floor-side panel floor 120. Since the seismic isolation floor-side panel floor 130 and the fixed floor-side panel floor 120 slide on the sliding surface S so that one of them can sink under the other in the operating state, It is possible to go back and forth between the seismic isolation floor 300 and the fixed floor 200 via the panel floor at any time in the state and the operating state.
