Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a support member for a cover plate that covers a space between two adjacent building members and a mounting structure for the cover plate.

[0002]

2. Description of the Related Art The width of a building (building) is limited according to its height and depth by the Building Standards Law. For this reason, when it is desired to have a width greater than the limited width at the height or depth, the building should be constructed with two adjacent buildings, and the space sandwiched between the two side surfaces of these two buildings should be the front side of the building. In many cases, a method of making the building look like a single building is adopted by covering it with a cover plate.

By the way, in the above-mentioned two-building building, each building vibrates independently due to an earthquake or the like, or the ground supporting one building sinks deeper than the other ground (differential settlement). As a result, both buildings may move to the left or right, or shift in the front-back direction or the vertical direction. In order to be able to cover the above space without damage even in such a case, a cover plate support member of pantograph structure that changes in expansion and contraction etc. following the movement of the building is installed between both buildings, thereby A method of supporting a plate is conventionally known.

In Japanese Utility Model Publication No. 7-47530, a cover plate support member having such a pantograph structure is attached to a building via a hinge to increase the amount of movement in each direction, and to prevent the amplitude from changing during an earthquake. It is shown that it can be applied to high-rise parts that grow larger and buildings built on soft ground such as landfills.

[0005]

However, in such a conventional cover plate support member, when the left and right buildings to which the cover plate support members are attached move vertically relative to each other, the structure of the pantograph causes There was a possibility that the upper end or the lower end would come into contact with the side surface of the building. Also, with the conventional cover plate support member, a large amount of movement could not be taken for the movement of shifting both ends of the pantograph link (fixed part to the building) in the link plane in the direction perpendicular to the expansion and contraction direction. , This cover plate support member is used laterally (the support parts at both ends are located above and below), and a seismically isolated building (with an isolator between the lower part of the building and the upper part of the building, the building swayed due to an earthquake, etc.) It was sometimes difficult to apply it to buildings where the amplitude of the upper part of the building was suppressed.

The present invention has been made in view of the above problems, and a cover plate supporting member and a cover plate that can obtain a large movable amount as compared with the conventional one and can be sufficiently applied to a seismic isolated building. It is intended to provide a mounting structure for.

[0007]

In order to achieve such an object, the present invention has a front surface portion and side surface portions extending at right angles from the end portions of the front surface portion, and the front surface portion is in the same plane. Is provided in a space between two adjacent building members (for example, the buildings 70 and 80 in the embodiment) which are located so as to face each other at their side surfaces, and cover the space from the front surface side. A cover plate supporting member for supporting the cover plate, which is fixed at a position facing each of the ends of both building members such that the direction of the swing axis is the same as the extending direction of the ends. A pair of hinges to which the pieces are attached and one end of which one ends are pivotally connected to the respective movable pieces of the pair of hinges so as to be rotatable about the front-rear axis 2
First arm member, one second arm member whose both ends are pivotally connected to the other ends of the two first arm members so as to be rotatable around the front-rear axis, and the central portion is the second arm. A third arm member pivotally connected to the central portion of the member so as to be rotatable around the front-rear axis and slidably mounted on the two first arm members at both ends in the axial direction; An elastic member (for example, the spring 51 in the embodiment) that urges the part on the one end side toward the hinge-side rotation shaft of the first arm member to which the one end is attached, The cover plate is attached to the center of the second arm member so as to be rotatable around the front-rear axis. Here, the length of the member means the distance between the rotary shafts at both ends.

In the cover plate supporting member having such a structure, the first arm member, the second arm member, and the third arm member.
A link mechanism composed of arm members is expandable / contractible within the link mechanism plane in response to a change in the three-dimensional position of a pair of hinges supporting both ends thereof, and is rotatable around the swing axis of the hinge. The two first arm members are always kept in parallel by the action of the third arm member biased by the elastic member, and the central portion of the link mechanism (that is, the central portion of the second arm member).
Is always in the middle of both hinges. Therefore, the cover plate can be stably supported even when both building members move in all directions in the up, down, front, back, left, and right due to an earthquake, etc., and the movable amount in each direction is greater than that of the conventional pantograph structure. Because it can be bigger,
It is also possible to use it in places where the shaking of the building could not be applied so far. Further, since the movable amount for the movement of shifting both ends of the link mechanism in the link plane in the direction perpendicular to the expansion / contraction direction can be made larger than in the conventional case, it can be sufficiently applied to a base-isolated building.

Here, if the third arm member has the same length as the second arm member, the third arm member can be positioned so as to overlap the second arm member, so that the above-mentioned link is provided. It can be maximally extended (it is then in a straight line) and maximally contracted. At this time, the movable amount of the cover plate supporting member becomes maximum. Here, the length of the member also means the distance between the rotary shafts at both ends.

In another cover plate supporting member according to the present invention, the direction of the swing axis is the same as the extending direction of the end portions of the two building members at the positions facing each other. And a pair of hinges having fixed pieces attached thereto, and two first arm members having one end pivotally connected to each movable piece of the pair of hinges so as to be rotatable around the front-rear axis. A second arm member whose both ends are pivotally connected to the other ends of the two first arm members so as to be rotatable around the front-rear axis, and a center portion of the second arm member rotates around the front-rear axis. A third arm member that is movably pivoted, and two fourth arms, one end of which is pivotally connected to both ends of the third arm member and the other end of which is pivotally connected to each of the two first arm members. And an arm member, and the cover plate includes a second arm member. It is adapted to be mounted for longitudinal-axis rotation at the center portion. With the cover plate supporting member having such a structure, the same effect as that of the cover plate supporting member having the above structure can be obtained.

The cover plate mounting structure according to the present invention is a cover plate mounting structure which is provided in a space between two adjacent building members and covers the space from the front surface side. A plurality of cover plate support members having any of the above configurations are provided in the extending direction of the end portions of both building members to support the cover plates, and the front faces of both building members are the same as the end portions. A pair of cover members (for example, the inner covers 91 and 92 in the embodiment) extending in the direction are provided, and the cover members cover both ends of the cover plate.

In the cover plate mounting structure having such a structure, since the cover members provided on both the building members cover both end portions of the cover plate, for example, the two building members move in the direction of separating from each other. Even if a gap occurs between the front surface of the building member and the cover plate (swings), such a gap cannot be seen from the front surface side of the building member, so the appearance is not impaired.

c and 42c are swingable around swing shafts 41a and 42a (vertical shafts).

The two first arm members 11 and 12 are the first
The arm member 11 is attached to the third movable piece 41c of the hinge 41 on the left side.
The first arm member 12 is rotatably pivoted about the front-rear axis by a pin P3, and the first arm member 12 is a movable piece 42 of the hinge 42 on the right side.
It is pivotally connected to c by a fourth pin P4 so as to be rotatable around the front-rear axis. Therefore, both the first arm members 11 and 12 are rotatable in the upper and lower planes with the third pin P3 or the fourth pin P4 as a fulcrum. The two first arm members 11 and 12 have the same length, that is, the length between the rotating shafts (pins) at both ends is equal.

The upper end side is pivotally connected to the other end of the right first arm member 12 (the side not pivotally connected to the hinge 42) by a sixth pin P6 so as to be rotatable around the front-rear axis. The length of the second arm member 21, that is, the length between the rotary shafts (pins) at both ends is substantially the same as that of the first arm members 11 and 12.

The third arm member 31 has a second central portion.
A seventh pin P7 is pivotally connected to the central portion of the arm member 21 so as to be rotatable around the front-rear axis. Further, as shown in FIGS. 4 and 5, at both end portions at the same distance from the central portion of the third arm member 31 (that is, the seventh pin P7), the roller 33 is provided with the roller 33 by the roller support bolt 32.
1 is mounted so as to be located on the front surface side of the first arm member 1 and the rollers 33 are formed on the rear surface side of the first arm members 11 and 12 (the groove portion 11 of the first arm member 11 on the left side).
(a is shown in FIG. 4) to the first arm members 11 and 12. Therefore, the third arm member 31 is in a state of being slidably mounted on the two first arm members 11 and 12 having both ends in the axial direction (axial direction of the first arm members 11 and 12). . Here, the distance between both rollers 33 is set to be equal to the distance between the fifth pin P5 and the sixth pin P6, so that the two first arm members 11 and 12 are always kept in parallel. You can do it. In addition, the fifth of the two first arm members 11 and 12
An end cap for preventing the rollers 33 from falling off is provided at the end on the side where the pin P5 or the sixth pin P6 is attached (the end cap 11b provided on the first arm member 11 is 1 and 4).

Further, as shown in FIGS. 1 and 3, a first hook 52 is provided on the rear surface side of the third arm member 31, and a second hook 53 provided on a base material 83 of the right building 80. A spring 51 is attached between the and.
Here, the first hook 52 is provided on the upper end side (on the side of the first arm member 12 on the right side) of the central portion of the third arm member 31, and the second hook 53 holds the first arm member 12 on the right side. Since the spring 51 is provided on the front and rear axis of the fourth pin P4 pivotally connected to the hinge 42, the spring 51 is
The upper end of the third arm member 31 is connected to the hinge 42 side pivot shaft of the right first arm member 12 (that is, the fourth pin P).
It is always biased toward 4).

As described above, the cover plate supporting member 1 having such a structure has the space S between the left and right buildings 70, 80.
A plurality of them are provided side by side vertically. As shown in FIG. 2, the cover plate supporting member 1 is attached such that the second arm member 21 is tilted slightly to the right as compared to the vertical state, but this is an example, and it may be mounted vertically or leftward. I do not care.

The cover plate 90 is a rectangular plate member extending in the direction of the space S, and is provided on the rear surface side of the cover plate 90.
Each of the mounting portions 90b (see FIG. 3) is supported in the space S by being coupled to the front end portion of the seventh pin P7 of the cover plate supporting member 1 (see FIG. 3). Also,
As shown in FIG. 7, there is a gap h between the lower end surface and the upper end surface of the two cover plates 90 provided on the upper and lower sides, and the buildings 70, 80 sway and the upper and lower cover plates 90 are shaken. Both cover plates 90 do not interfere with each other even when 90 moves toward each other. Further, the gap h is closed by a back plate 90a provided on the rear surface side of the lower cover plate 90, so that the upper and lower cover plates 90 can be continuously seen in appearance.

Further, as shown in FIG. 3, the left and right hinges 4 are provided.
On the front side of the movable pieces 41c, 42c of 1, 42, inner covers 91, 92 that are located rearward of the cover plate 90 in parallel with the cover plate 90 are provided extending vertically along the base materials 73, 83. (See also Figure 6). In addition, the front surface portion 73 of each of the left and right base materials 73, 83
Outer covers 93, 94 are provided on the outer side of both hinges 41, 42 of a, 83a (see FIG. 3), whereby the base materials 73, 74 and these base materials 7 are provided.
It covers the rows of hinges 41 and 42 arranged vertically along 3, 73 (see FIG. 6).

Next, the movement of the cover plate supporting member 1 will be described. Here, as shown in FIG. 2, it is assumed that the cover plate support member 1 is attached in a state in which the second arm member 21 is slightly inclined to the right rather than the vertical state.

First, a case will be described in which the left and right buildings 70, 80 are moved (swayed) in the left and right opposite directions due to an earthquake or the like. In addition, in FIGS. 8 to 12 used in the following description,
Cover plate support member 1 and building 7 supporting it
Only part of 0,80 is shown. FIG. 8A shows a standard state (initial state) in which both buildings 70 and 80 are not shaken. When the two buildings 70, 80 swing and move away from each other, the hinges 41, 42 also separate, so that the first arm members 11, 12 also separate from each other. At this time, the second arm member 21 rotates about the seventh pin P7 in the direction of arrow B in FIG. 8A, and the third arm member 31 moves to the seventh pin P7.
Rotate in the direction of arrow A around.

As shown in FIG. 8B, when the first arm members 11 and 12 are perpendicular to the second arm member 21, the third arm member 31 overlaps with the second arm member 21. At this time, the first arm member 1 of the third arm member 31
The roller 33 on the first side overlaps with the fifth pin P5, and the roller 33 on the first arm member 12 side of the third arm member 31 overlaps with the sixth pin P6. In this state, the third arm member 3
1 is a thought point, but since the upper end side is urged toward the fourth pin P4 side by the spring 51, both buildings 70,
When 80 is further separated, the third arm member 31 remains overlapping with the second arm member 21, and the seventh pin P7
Rotate in the direction of arrow B.

FIG. 8C shows a state in which the cover plate supporting member 1 is maximally extended. At this time, the link mechanism including the first arm members 11 and 12, the second arm member 21, and the third arm member 31 is in a linearly extended state. When the link mechanism is extended to the maximum extent as described above, the length of the link mechanism in the left-right direction is about 1.5 times that in the standard state shown in FIG.

On the other hand, when the two buildings 70, 80 are moved (swayed) from the standard state shown in FIG. , 12 also approach each other. At this time, the second arm member 21 rotates about the seventh pin P7 in the direction of arrow A in FIG. 9A, and the third arm member 31 rotates about the seventh pin P7 in the direction of arrow B. (See FIG. 9B). Figure 9
(C) shows a state in which the cover plate supporting member 1 contracts to the maximum extent. When the cover plate supporting member 1 is contracted to the maximum extent as described above, the horizontal length of the link mechanism is about 0.5 times the distance in the standard state shown in FIG. 9 (A).

Next, a case where the left and right buildings 70, 80 move (sway) upside down will be described. Figure 1
0 (A) shows a standard state in which both buildings 70 and 80 are not shaken. When both buildings 70 and 80 swing and the left building 70 moves downward and the right building 80 moves upward, the left hinge 41 descends and the right hinge 4 moves.
2 rises. At this time, the first arm member 11 on the left side moves the fifth pin P5 to the right, and the first arm member 1 on the right side is moved.
2 moves the 6th pin to the left. As a result, the second arm member 21 rotates in the direction of arrow A in FIG. 10A, and the third arm member 31 rotates in the direction of arrow A at a faster rotation speed than the second arm member 21.

As shown in FIG. 10B, when the first arm members 11 and 12 are perpendicular to the second arm member 21, the second arm member 21 and the third arm member 31 overlap each other. At this time, the roller 33 of the third arm member 31 on the first arm member 11 side overlaps with the fifth pin P5, and the roller 33 of the third arm member 31 on the first arm member 12 side is the sixth pin P5.
It overlaps with the pin P6. In this state, the third arm member 31 becomes a consideration point, but since the upper end side is urged toward the fourth pin P4 side by the spring 51, both buildings 7
When 0 and 80 further move up and down, the third arm member 31 rotates in the direction of arrow B about the seventh pin P7 while keeping the state of overlapping with the second arm member 21. Figure 10
(C) shows a state in which the cover plate supporting member 1 is maximally extended, and at this time, the link mechanism is in a linearly extended state.

On the other hand, when the building 70 on the left side moves upward and the building 80 on the right side moves downward from the standard state shown in FIG. 11A, the hinge 41 on the left side moves up and the hinge 41 on the right side moves up. The hinge 42 descends. At this time, the first arm member 11 on the left side moves the fifth pin P5 leftward, and the first arm member 12 on the right side moves the sixth pin P6 rightward. As a result, the second arm member 21 rotates in the direction of arrow B in FIG. 11A, and the third arm member 31 rotates in the direction of arrow A.

As shown in FIG. 11B, when the first arm members 11 and 12 are perpendicular to the second arm member 21, the second arm member 21 and the third arm member 31 overlap each other. In this state, the third arm ratio 31 becomes a consideration, but since the upper end side is biased toward the fourth pin P4 side by the spring 51, when both the buildings 70 and 80 move further up and down. , The third arm member 31 remains overlapped with the second arm member 21, and the seventh pin P7
Rotate in the direction of arrow B. FIG. 11C shows a state in which the cover plate supporting member 1 is maximally extended, and at this time, the link mechanism is in a linearly extended state.

Next, the case where the left and right buildings 70, 80 have moved (swayed) in the front and rear opposite directions will be described. 12
(A) shows a standard state in which both buildings 70 and 80 are not shaken. When the two buildings 70, 80 swing and the left building 70 moves backward and the right building 80 moves forward, the left hinge 41 moves backward and the right hinge 42 moves forward. Move to. At this time, the first arm member 1
1, 12, second arm member 21 and third arm member 31
The link mechanism consists of the movable piece 4 of the left and right hinges 41 and 42.
While swinging 1c and 42c around the swing shafts 41a and 42a, the left side is rotated backward and the right side is rotated forward. At the same time, this link mechanism extends as if the buildings 70, 80 were separated in the left-right direction.

FIG. 12B shows the cover plate supporting member 1
Shows the state of being extended to the maximum. At this time, the link mechanism is in a linearly extended state. However, it is necessary to set the shape of the base material 83 so that the first arm member 12 and the base material 83 do not interfere with each other in this state. When the building 70 on the left moves forward and the building 80 on the right moves backward, the operation of the cover plate support member 1 is completely opposite to the above case (the explanation of the operation is omitted). .

As described above, in the cover plate supporting member 1, the link mechanism including the first arm member 11, 12, the second arm member 21, and the third arm member supports the pair of hinges 41, 42 supporting both ends thereof. The hinge 4 can be expanded and contracted in the plane of the link mechanism in response to changes in the three-dimensional position of
The first arm members 11 and 12 are kept parallel to each other by the action of the third arm member 31 urged by the spring 51. The central portion of the link mechanism (that is, the central portion of the second arm member 21) is always located at the intermediate position between the hinges 41 and 42. Therefore, even when both buildings 70, 80 move in all directions of up, down, front, back, left, and right due to an earthquake or the like, the central portions of the two upper and lower cover plate support members 1 (that is, the seventh pin P7) are always on the same straight line. The cover plate 90 can be stably supported while being kept in the position. In the above example, the cover plate 90 is attached by the upper and lower cover plate support members 1, but it is not necessary that the cover plate 90 is the two cover plate support members 1 and the cover plate support members 1 are three or more. You can attach it with.

Since the movable amount in each direction can be made larger than that of the conventional pantograph structure, it can be used in a place where the shaking of the building cannot be applied so far. The table shown in FIG. 13 shows the left and right buildings 7
This cover plate supporting member 1 when the distance (building gap) between the side surfaces 72, 82 of 0, 80 is 400 mm
The movable amount in each direction of (this product) is shown in comparison with a cover plate supporting member (conventional product) having a conventional pantograph structure having the same size as the cover plate supporting member 1. From this table, it is understood that the cover plate supporting member 1 can have a significantly larger movable amount than the cover plate supporting member having the conventional pantograph structure.

If the third arm member 31 has a length equal to that of the second arm member 21 as in the cover plate supporting member 1 (as described above, the term "length" means the rotation axis of both ends). Between the second arm member 31 and the second arm member 31
Since it is possible to overlap with the arm member 21, the link mechanism including the first arm members 11 and 12, the second arm member 21, and the third arm member 31 can be extended to the maximum extent (this Sometimes becomes straight),
Moreover, since the contraction can be maximized, the movable amount of the cover plate support member 1 can be maximized.

In the case where the two buildings 70 and 80 are separated from each other, for example, when the two buildings 70 and 80 are separated from each other in the left-right direction or are moved in the front-rear direction, the left and right ends of the cover plate 90 are removed. The parts are separated from the ends of the buildings 70, 80 to form a gap, but the inner covers 91, 92 are provided at the ends of the structures 70, 80 (base materials 73, 83) as described above. Therefore, such a gap is covered, and the space S cannot be seen from the front surfaces 71, 81 of the buildings 70, 80. Further, as described above, the base materials 73, 84 and the hinges 41, 42 are covered with the outer covers 93, 94, and these members are not visible from the front portions 71, 81.

A modification of the cover plate supporting member 1 is shown in FIG. The cover plate support member 101 is
Third arm member 31 in the cover plate support member 1
Instead of the second arm member 21
The third pivotally connected by a pin P7 so as to be rotatable around the front-rear axis
One end is pivotally connected to the arm member 103 and both ends of the third arm member 103 by an eighth pin P8 and a ninth pin P9, and the other end is a tenth member to each of the two first arm members 11 and 12. It is configured to have two fourth arm members 104 and 105 pivotally connected by a pin P10 and an eleventh pin P11. The spring 51 used in the cover plate supporting member 1 described above is unnecessary.

In the cover plate support member 101 having such a structure, the link mechanism composed of the first arm members 11 and 12, the second arm member 21, the third arm member 103 and the fourth arm members 104 and 105 is used. It is expandable and contractable in response to a change in a pair of three-dimensional positions supporting both ends, and is rotatable around the swing shafts 41a, 42a of the hinges 41, 42, and is located at the central portion (second arm member) of the link mechanism. Since the central portion (21) is always located at the intermediate position between the hinges 41 and 42, the cover plate supporting member 1 having the above-described configuration is
The same effect as can be obtained.

Here, the distance between the seventh pin P7 and the eighth pin P8 and the distance between the seventh pin P7 and the ninth pin P9 are both the distance between the seventh pin P7 and the fifth pin P5 (or the seventh pin P7). The distance between the pin P7 and the sixth pin P6), and the eighth
Distance between pin P8 and tenth pin P10 and ninth pin P9
It is preferable that the distances between the 11th pin P11 and the eleventh pin P11 are both equal to the distance between the seventh pin P7 and the fifth pin P5 (or the distance between the seventh pin P7 and the sixth pin P6). With this configuration, the third arm member 103 can be positioned so as to overlap the second arm member 21, and thus the first arm member 1
1, 12, second arm member 21, third arm member 103
Since the link mechanism including the fourth arm members 104 and 105 can be extended to the maximum extent (in a straight line at this time) and can be contracted to the maximum extent, the cover plate supporting member 101 can be moved. The amount can be maximized.

Further, in such a cover plate supporting member 1, since the movable amount for the movement of displacing both ends of the link mechanism in the direction perpendicular to the expansion / contraction direction within the link plane can be made larger than in the conventional case, It is fully applicable to quake buildings. Squid will be described for the case where the cover plate support member 1 is used in a seismic isolated building.

The seismic isolated building shown in FIG.
Isolator 1 in the space S between 0 and the upper part 120 of the building
30 and is configured to suppress the amplitude of the upper part 120 of the building when the building shakes due to an earthquake or the like. The lower part 110 of the building and the upper part 120 of the building have their front parts 111, 121 located in the same plane, and side parts (upper surface part and lower surface part) extending at right angles from the end parts of these front part 111, 121. 112 and 122 are provided so as to face each other vertically. Further, the Z-shaped base materials 113 and 123 extending in the left-right direction are attached to the end portions (these base materials 113 and 123 have the same structure as the base materials 73 and 83 described above, and therefore the detailed description will be omitted). (Illustration is omitted).

When the cover plate supporting member 1 is attached to such a seismic isolated building, the above-mentioned two buildings 7 are installed.
Unlike the case where it is provided between 0 and 80, as shown in FIG. 16, both hinges 41 and 42 are vertically opposed to each other and one hinge 4
The other hinge 42 is provided above 1, and the cover plate supporting member 1 is attached in the most contracted state (this is the standard state). This is because the height dimension of the isolator 130 is kept constant, and the cover plate supporting member 1 does not at least contract (it may expand, as will be described later). The cover plate support member 90, the inner covers 91 and 92, and the outer covers 93 and 94 are attached in the same manner as the left and right buildings 70 and 80 so as to extend in the left and right direction.

In such a base-isolated building, the movement of the cover plate supporting member 1 when the upper part 120 of the building moves relative to the lower part 110 of the structure (sways) to the right due to an earthquake or the like will be described. FIG. 17A shows a standard state in which the seismic isolated building is not shaken. Top 12 of the building
When 0 moves relative to the lower part 110 to the right, the upper hinge 42 moves to the right relative to the lower hinge 41. This causes the second arm member 21 to move to the position shown in FIG.
(B) rotates in the direction of arrow B, and the third arm member 31 rotates in the direction of arrow A.

As shown in FIG. 17C, when the first arm members 11 and 12 are perpendicular to the second arm member 21, the second arm member 21 and the third arm member 31 overlap each other. At this time, the roller 33 of the third arm member 31 on the first arm member 11 side overlaps with the fifth pin P5, and the roller 33 of the third arm member 31 on the first arm member 12 side is the sixth pin P5.
It overlaps with the pin P6. In this state, the third arm member 31 becomes a thought point, but since the upper end side is biased by the spring 51 toward the fourth pin P4 side,
When 20 further moves to the right, the third arm member 3
1 rotates in the direction of arrow B about the seventh pin P7 while keeping the state of overlapping with the second arm member 21. FIG. 17 (D)
Shows a state in which the cover plate supporting member 1 is maximally extended. At this time, the first arm members 11, 12,
The link mechanism including the arm member 21 and the third arm member 31 is in a linearly extended state.

On the other hand, when the upper part 120 of the building moves relative to the left side of the lower part 110 of the structure (sways) from the standard state shown in FIG. 18A, the upper hinge 42 is the lower hinge. Relative to the left with respect to 41. This makes the second
The arm member 21 rotates in the direction of arrow B in FIG. 18B, and the third arm member 31 rotates in the direction of arrow A.

As shown in FIG. 18C, when the first arm members 11 and 12 are perpendicular to the second arm member 21, the second arm member 21 and the third arm member 31 overlap. At this time, the roller 33 of the third arm member 31 on the first arm member 11 side overlaps with the fifth pin P5, and the roller 33 of the third arm member 31 on the first arm member 12 side is the sixth pin P5.
It overlaps with the pin P6. In this state, the third arm member 31 becomes a thought point, but since the upper end side is biased by the spring 51 toward the fourth pin P4 side,
When 20 further moves to the left, the third arm member 3
1 rotates in the direction of arrow B about the seventh pin P7 while keeping the state of overlapping with the second arm member 21. FIG. 18 (D)
Shows the state where the cover plate support member 1 is extended to the maximum, and at this time, the link mechanism is in a state where it is extended in a straight line.

Next, the upper part 120 of the building is the lower part 11 of the structure.
Description will be made regarding the case of moving relative to 0 (shaking). FIG. 19 (A) shows a standard state where the seismic isolated building is not shaken. The upper building 120 is the lower building 110
On the other hand, when the hinges 42 move forward relative to each other, the upper hinge 42 moves forward relative to the lower hinge 41. At this time, the above-mentioned link mechanism operates the movable piece 41 of the upper and lower hinges 41 and 42.
The c and 42c are rotated so as to rotate the upper side forward while swinging the swing shafts 41a and 42a. At the same time, this link mechanism, in the example of the buildings 70, 80,
The two buildings 70, 80 extend as if they were separated in the left-right direction.

FIG. 19B shows the cover plate supporting member 1
Shows the state of being extended to the maximum. At this time, the link mechanism is in a linearly extended state. However, it is necessary to set the shape of the base material 123 so that the first arm member 12 and the base material 123 do not interfere with each other in this state. Also,
When the upper part 120 of the building moves rearward relative to the lower part 110 of the structure, the operation of the cover plate supporting member 1 is completely opposite to the above case (the explanation of the operation is omitted).

As described above, the cover plate supporting member 1 is provided between the building lower part 110 and the building upper part 120, which face each other with the isolator 130 in between, in the base-isolated building 110. It is possible to cover the space (i.e., the isolator 130), and it is possible to obtain the same effect as in the case where the space is provided between the left and right buildings 70 and 80 described above. It is preferable that the cover plate supporting member 1 is attached in the most contracted state as described above because it can correspond to the large relative movement of the upper part 120 of the building, but it is not always in the most contracted state. You don't have to attach it.

The table shown in FIG. 20 shows side surfaces (upper surface and lower surface) 112 of the lower building 110 and the upper building 120.
A conventional pantograph having the same amount of movable amount in each direction of the cover plate supporting member 1 (this product) when the distance between the 122 (upper and lower clearances) is 200 mm. It is shown in comparison with a cover plate supporting member (conventional product) having a structure. However, since the conventional pantograph structure cannot be installed between the upper and lower gaps of 200 mm, the upper and lower gap is set to 282 mm which is the minimum distance in which the conventional product can be installed. As can be seen from this table, the movable amount of the cover plate supporting member 1 can be made significantly larger than that of the cover plate supporting member having the conventional pantograph structure even in the base-isolated building. The cover plate supporting member 101 shown in FIG. 14 can be used for the above-described seismic isolated building.

[0051]

As described above, in the cover plate supporting member according to the present invention, the first arm member and the second arm member are provided.
A link mechanism including an arm member and a third arm member,
A pair of hinges that support both ends of the hinge can expand and contract within the plane of the link mechanism in response to changes in the three-dimensional position of the hinge, and can rotate around the swing axis of the hinge. Three
By the action of the arm members, the two first arm members are always kept in parallel, and the central portion of the link mechanism (that is, the central portion of the second arm member) is always located at the intermediate position between the hinges. Therefore, the cover plate can be stably supported even when both building members move in all directions in the up, down, front, back, left, and right due to an earthquake, etc., and the movable amount in each direction is greater than that of the conventional pantograph structure. Since it can be made larger, it can be used in places where the shaking of the building could not be applied so far. Further, since the movable amount for the movement of shifting both ends of the link mechanism in the link plane in the direction perpendicular to the expansion / contraction direction can be made larger than in the conventional case, it can be sufficiently applied to a base-isolated building.

Further, in the cover plate mounting structure according to the present invention, since the cover members provided on both building members cover both end portions of the cover plate, for example, in the direction in which both building members are separated from each other. Move (sway)
Even if there is a gap between the front surface of the building member and the cover plate, such a gap cannot be seen from the front surface side of the building member, so the appearance is not impaired.
