BACKGROUND OF THE INVENTION
The present invention relates to a structure of an expansion / contraction crossing passage provided between passages of two buildings adjacent to each other.
[0002]
[Prior art]
FIG. 8 is a horizontal cross-sectional view showing a conventional crossover path 200 in a simplified manner. This conventional technique is disclosed in Japanese Patent Laid-Open No. 10-131307. In this conventional technique, the first and second buildings 201 and 202 which are adjacent to each other with a gap G in the substantially horizontal first direction A1 and A2 are substantially in the second direction perpendicular to the first direction A1 and A2. First and second passages 203 and 204 extending along B1 and B2 are provided, and each side portion on the side close to each other of the passages 203 and 204 is upward (front side perpendicular to the paper surface of FIG. 8). Standing passage side walls 205 and 206 are provided, respectively.
[0003]
Passage openings 207 and 208 are formed in the respective passage side walls 205 and 206 so as to face the first directions A1 and A2, and the passage side wall 205 of one building 201 is connected to the passage 203 through the passage opening 207. A cantilever passage structure 209 that communicates with the passage side wall 205 is formed integrally with the cantilever passage structure 209 and the passage 204 of the second building 203.
[0004]
In the crossing passage 200, one end portion on the first building 201 side is supported by a roller (not shown) so as to be movable in the first direction A1, A2, and the other end portion on the second building 202 side is supported on the passage 204 in the second direction B1, The floor body 210 is movably supported by B2, and has a pair of handrails 211, 212 fixed to the left and right sides of the floor body 210 in the first direction A1, A2.
[0005]
The handrails 211 and 212 extend along the first directions A1 and A2 and are fixed to the floor body 210 in parallel with each other, and the second building of the first handrail portions 213 and 214. 202 has second handrail portions 215 and 216 extending from the end portion on the 202 side and extending substantially perpendicularly in directions away from each other in the second directions B1 and B2.
[0006]
  Each first handrail portion 213, 214Is the horizontal direction (in FIG. 8) with respect to the inner surfaces 217 and 218 of the passage opening 208 in the initial installation state in which the first and second buildings 201 and 202 are not relatively displaced in the second direction B. Are spaced apart at substantially equal intervals ΔL1 and ΔL2 in the direction parallel to the paper surface.
[0007]
  Even when the buildings 201 and 202 are displaced relative to each other in the second directions B1 and B2 due to an earthquake or the like by the intervals ΔL1 and ΔL2, the first handrail portions 21 are provided.3, 214Is prevented from coming into contact with the inner surfaces 217 and 218, and the intervals ΔL1 and ΔL2 are separated from the passage side wall 206 by the second handrail portions 215 and 216 (see FIG.8In the second direction B1, B2 between the buildings 201, 202 can be allowed.
[0008]
Further, since the floor 210 is movably supported by the cantilever passage structure 209 of the first building 201, the buildings 201 and 202 are relatively displaced in the first directions A1 and A2 by the earthquake or the like. Even if this occurs, displacement of the cantilever passage structure 209 and the floor body 210 in the first directions A1 and A2 can be allowed.
[0009]
As described above, in this conventional technique, the passages 200 and 204 are parallel to each other, and the crossing passage 200 is spanned between the passages 203 and 204 at a substantially right angle so that the handrail is substantially continuous. A crossing passage is realized.
[0010]
FIG. 9 is a perspective view showing a simplified transition passage 300 according to another conventional technique. This conventional technique is disclosed in Japanese Patent Laid-Open No. 9-317118. In this conventional technique, the first and second buildings 301 and 302 that are adjacent to each other with a gap G in the substantially horizontal first directions A1 and A2 are substantially straight along the first directions A1 and A2. Extending passages 303 and 304 are respectively provided, and a cantilevered passage structure 306 is continuous with the passage 303 in the first direction A1 and A2 on the opposing wall surface 305 facing the second building 302 of the first building 301. Formed.
[0011]
One end portion of the floor body 307 is supported by the cantilever passage structure 306 so as to be movable in the first directions A 1 and A 2, and the other end portion of the floor body 307 extends from the opposing wall surface 308 of the second building 302. It is supported by a support portion 309 protruding toward the first building 301 side. In the cantilever passage structure 306, handrail walls 311 and 312 rising upward are formed on both left and right sides of the floor slab 310 in the first direction A1 and A2.
[0012]
On the opposite wall surface 308 of the second building 302, handrails 317 and 318 are attached to both sides of the passage opening 316 by hinges 314 and 315 so as to be angularly displaceable in the directions of arrows C1 and C2; D1 and D2 around the vertical axis. It is done. Pins 319 and 320 are respectively fixed to the free ends of the handrail walls 311 and 312, and both vertical ends of the pins 319 and 320 are close to the free ends of the upper and lower portions of the handrails 317 and 318. The guide slots 321 and 322 are formed so as to be movable. The handrails 317 and 318 are configured such that the relative displacements of the buildings 301 and 302 in the second directions B1 and B2 by the angular displacement and the relative displacements in the first direction A1 and A2 by the pins 319 and 320, respectively. It can accept | permit according to the displacement in the guide long holes 321 and 322, respectively.
[0013]
Thus, in this conventional technique, even if the first and second buildings 301, 302 are relatively displaced in the first direction A1, A2 and the second direction B1, B2 due to an earthquake or the like, the displacement is reduced. A continuous passage between the passages 303 and 304 of the buildings 301 and 302 is formed regardless of the relative displacement between the buildings 301 and 302 so as not to allow a dangerous gap for a passerby. It is configured so that it can be realized.
[0014]
[Problems to be solved by the invention]
In the conventional technique shown in FIG. 8 (Japanese Patent Laid-Open No. 10-131307), it is substantially perpendicular to the direction in which the passages 203 and 204 of the buildings 201 and 202 extend, that is, the second directions B1 and B2. Since the passage 200 is provided in the first directions A1 and A2, the handrails 211 and 212 extend along the first directions A1 and A2 and are parallel to the floor body 210 as measures for preventing the passers-by from falling. The first handrail portions 213 and 214 to be fixed and the first handrail portions 213 and 214 bend and extend substantially at right angles in the directions away from each other in the second directions B1 and B2 from the end of the second building 202 side. Each of the second handrail portions 215 and 216 has a structure in which each of the second handrail portions 215 and 216 is expanded to both sides (that is, the first direction A1 and A2) on the passage space side to avoid interference with the passage side wall 206. Adopt However, when the passages 203 and 204 extend substantially straight in the first direction A1 and A2 with respect to the crossing passage 200, particularly when the passage 204 of the second building 202 extends in the first direction A1 and A2. In this case, spaces m1 and m2 for allowing movement of the second handrail portions 215 and 216 corresponding to the intervals ΔL1 and ΔL2 must be secured on both sides of the second handrail portions 215 and 216.
[0015]
Therefore, the 2nd building 202 which can employ | adopt this transit passage 200 will be restricted to the structure which can ensure the space m1, m2 for permitting the said movement at least in the vicinity of the opening 208 for passages. There's a problem. As one of the cases where the spaces m1 and m2 cannot be secured, a building structure in which the passage side wall on the second building 202 side extends in parallel with the first directions A1 and A2 is assumed. In this case, it can be considered that one or both of the second handrail portions 215 and 216 are formed in the respective side walls of the passage extending in the first direction A1 or A2 so that the second handrail portion 215 or 216 can freely play in the second direction. When one or both of the second handrail portions 215 and 216 are inserted into such an opening, one or both of the second portions 215 and 216 that are inserted through the opening protrude from the passage side wall to the outside, and the building There is a problem that the aesthetics of the design will be degraded.
[0016]
Further, in the conventional technique shown in FIG. 9 (Japanese Patent Laid-Open No. 9-317118), the passages 303 and 304 and the crossing passage 300 are provided in a substantially straight line. On the outer side, the handrail walls 311 and 312 of the cantilever passage structure 306 are provided, and an interval ΔL3 between the handrail walls 311 and 312 is determined by the width W1 of the passage 303 of the first building 301 and the second building 302. It must be configured to be larger than the width W2 of the passage 304 (ΔL3> W1> W2) to avoid interference when the handrails 317 and 318 are angularly displaced. Therefore, the first building 301 requires areas m3 and m4 to which cantilevered passage structures 306 including handrail walls 312 and 313 can be attached on both sides of the passage opening 323 on the opposite wall surface 324, and There is a problem that the transition passage 300 cannot be provided unless the first building 301 can secure the areas m1 and m2.
[0017]
Accordingly, an object of the present invention is to provide an expansion / contraction passage that can be easily installed without deteriorating the appearance of each building and without requiring a large mounting area compared to the passage of each building. It is.
[0018]
[Means for Solving the Problems]
  In the first aspect of the present invention, a floor plate is provided over each passage opened in each opposing wall surface of the first and second buildings adjacent to each other with a gap in a substantially horizontal first direction,
  The first and second buildings each have a handrail wall that rises upward from an end portion on the outdoor side of the passage,
  The floor plate is supported by the first building so as to be displaceable in the first direction within the passage, and is supported so as to be displaceable in a substantially horizontal second direction that intersects the first direction outside the passage with respect to the second building. And
  The left and right sides of the floor plate with respect to the first direction are respectively provided with fixed handrails that rise upward,
  A movable handrail portion is provided between at least one of the fixed handrail portions and the second building,
  The movable handrail part isInside the handrail wallIt has two fence bodies that are provided in a state where they are folded over each other,
  One end of one fence body and one end of the other fence body are connected so as to be angularly displaceable around a vertical axis,
  The other end of the one fence body is connected to a passage surface facing the passage of the handrail wall so as to be angularly displaceable around a vertical axis,
  The other end of the other fence body is an expansion / contraction passage characterized by being connected to the fixed handrail portion so as to be angularly displaceable about a vertical axis.
[0019]
According to the present invention, at least one of the handrails is constituted by a fixed handrail portion and a movable handrail portion, and the movable handrail portion itself is configured to be bendable around a vertical axis. When moving in a first direction that is relatively close to or away from the ground due to an earthquake or the like, or when it is displaced in a second direction that is the front-rear direction when each building is viewed in front, the movable handrail section itself bends. The relative displacement of each building can be absorbed and allowed without significantly protruding from the outer wall surfaces of the first and second buildings.
[0020]
The handrail having such a movable handrail portion and the fixed handrail portion may be provided on both sides of the floor plate, or may be provided only on one side that is not desired to protrude from the building.
[0021]
The floor plate on which each handrail is provided is supported by the first building so as to be displaceable in the first direction in the passage, and is substantially horizontal in the second building and intersects the first direction outside the passage. Since it is supported so as to be displaceable in two directions, the displacement in the first direction in which the buildings are relatively close to or apart from each other can be absorbed by the movement in the first direction in the passage of the first building. The relative displacement of each building in the second direction can be absorbed by the floor plate moving in the second direction with respect to the second building outside the passage of the second building. In this way, a crossing passage is provided between the passages of each building without requiring a large attachment area compared to the passage width, and a large gap is generated such that a passerby falls or a foot fits in. Without it, a continuous passage can be realized in traffic.

A handrail 13 can be provided.
[0048]
Further, from the initial state as shown in FIG. 7 (1), due to an earthquake or the like, for example, as shown in FIG. If the floor plate 12 to which the handrails 13 and 14 are fixed is guided by the guide rail 29, the same as the first building 2 with respect to the second building 3 Displace in the direction. The handrail 13 follows the displacement of the first and second buildings 2 and 3 as described above, and the movable handrail portion 16 is angularly displaced counterclockwise around the axis L1 with respect to the handrail wall 11 as viewed from above. At the same time, it can be displaced with respect to the floor plate 12 and the fixed handrail portion 15 in the extending direction of the movable handrail portion 16, and can be angularly displaced about the axis L2 counterclockwise as viewed from above. Accordingly, the handrail 13 can be provided continuously between the handrail walls 10 and 11 while allowing the first and second buildings 2 and 3 to be displaced to the state shown in FIG. Moreover, the handrail 14 has the part 14b extended in the 2nd direction B along the building main body 5 of the 2nd building 3, and a state as shown in FIG. 7 (4) of the 1st and 2nd buildings 2 and 3 Even if the floor plate 12 and the outer wall of the second building 3 are separated from each other by the displacement, the handrail 14 can be provided continuously between the outer walls 17 and 18.
[0049]
Further, from the initial state as shown in FIG. 7 (1), due to, for example, an earthquake, as shown in FIG. If the floor plate 12 to which the handrails 13 and 14 are fixed is guided by the guide rail 29, the same as the first building 2 with respect to the second building 3 Displace in the direction. The handrail 13 follows such displacement of the first and second buildings 2 and 3, and the movable handrail portion 16 is angularly displaced clockwise around the axis L <b> 1 with respect to the handrail wall 11 as viewed from above. At the same time, it can be displaced in the extending direction of the movable handrail portion 16 with respect to the floor plate 12 and the fixed handrail portion 15, and can be angularly displaced clockwise around the axis L2 as viewed from above.
[0050]
Accordingly, the handrail 13 can be provided continuously between the handrail walls 10 and 11 while allowing the first and second buildings 2 and 3 to be displaced to the state shown in FIG. The handrail 14 extends to the building main body 5 of the second building 3, continues to the outer wall 18 of the building main body 5, and continuously between the outer walls 17 and 18 via the outer wall 3 a facing the first building 2. A handrail 14 can be provided.
[0051]
Thus, the passage 35 can be formed by the floor plate 12 over the passages 8 and 9 of the first and second buildings 2 and 3, and in order to prevent a passerby from falling on the floor plate 12, Handrails 13 and 14 rising from both sides are respectively provided. One handrail 13 has a fixed handrail portion 15 and a movable handrail portion 16. The fixed handrail portion 15 is provided along the handrail wall 10 of the first building 2, and the floor plate 12 moves relative to the first building 2 with relative displacement of the first and second buildings 2 and 3. Even if it is displaced, a large gap is not formed between passersby and the handrail wall 10.
[0052]
In addition, since the two rails are connected to the movable handrail portion 16 so as to be angularly displaceable around the vertical axis L3, the fixed handrail portion 15 can be arranged as close as possible to the second building 3. A large gap is not formed between the second building 3 and the fixed handrail portion 15 so that a passerby can be fitted therein. As described above, even when the relative displacement between the first and second buildings 2 and 3 is utilized to the maximum extent of the gap G between the first and second buildings 2 and 3, and the movable handrail portion 16 is angularly displaced. It is possible to allow a large relative displacement between the buildings 2 and 3 in the first and second directions A and B without generating a large gap.
[0053]
As a result, even if the first and second buildings 2 and 3 are relatively largely displaced, a large continuous displacement passage can be provided across the handrail walls 10 and 11 while allowing the large displacement. it can.
[0054]
Further, by configuring the handrail 13 with the fixed handrail portion 15 and the bendable movable handrail portion 16, the handrail 13 extends along the handrail walls 10 and 11 in the initial installation state. 11 does not protrude outward. Therefore, it has an excellent appearance, and is provided on the floor plate 12 for connecting the passages 8 and 9 formed outside the building main bodies 4 and 5 as described above. It can be suitably implemented as a handrail on the space S side.
[0055]
Further, in the handrail attachment structure 60, the handrails 13 and 14 can be attached by fixing the support 63 to the plate-like floor plate 12 by forming the rising portion 62 on the plate-like floor plate 12. The rising portion 62 is connected to the base portion 61 by two ribs 66 and 67 arranged on both sides of the column 63, and an external force is applied to the handrails 13 and 14 by a passerby pressing the handrails 13 and 14, for example. Even if the sway acts, it is possible to prevent the rising portion 62 that fixes the lower end portion 63a of the column 63 from being angularly displaced with respect to the base portion 61, and the handrails 13 and 14 can be firmly attached to the floor plate 12. . This attachment structure part 60 can be suitably implemented as an attachment structure for the handrails 13 and 14 of the stretchable floor plate 12 provided between the two buildings 2 and 3.
[0056]
In another embodiment of the present invention, the handrail 13 having the movable handrail portion 16 and the fixed handrail portion 15 as described above may be provided on both sides of the floor plate 12. Also with such a configuration, it is possible to achieve the same effect as the above-described embodiment.
[0057]
【The invention's effect】
  According to the present invention, at least one of the handrails is configured by a fixed handrail portion and a movable handrail portion, and the movable handrail portion itself is configured to be bendable around a vertical axis, so that each building When moving in a first direction that is relatively close to or away from the ground due to an earthquake or the like, or when it is displaced in a second direction that is the front-rear direction when each building is viewed in front, the movable handrail section itself bends. The relative displacement of each building can be absorbed and allowed without significantly protruding from the outer wall surfaces of the first and second buildings.
  In addition, since the two handrails are connected to the movable handrail portion so as to be angularly displaceable around the vertical axis, the fixed handrail portion can be arranged as close as possible to the second building. A large gap is not formed between the door and the fixed handrail portion so that a passerby can be fitted therein. In this way, the relative displacement of the first and second buildings can be maximized using the gap between the first and second buildings, and even if the movable handrail portion is angularly displaced, a large gap is not generated. It is possible to allow a large relative displacement between the buildings.
  Accordingly, even if the first and second buildings are relatively displaced, it is possible to allow a large displacement and to provide a substantially continuous transition passage when passing through each handrail wall.
[0058]
The floor plate on which each handrail is provided is supported by the first building so as to be displaceable in the first direction in the passage, and is substantially horizontal in the second building and intersects the first direction outside the passage. Since it is supported so as to be displaceable in two directions, the displacement in the first direction in which the buildings are relatively close to or apart from each other is absorbed by the movement in the first direction in the passage of the first building, and each building The relative displacement in the second direction is absorbed by the movement of the floor plate in the second direction with respect to the second building outside the passage of the second building. Compared to the passageway without requiring a large attachment area, a continuous passageway can be realized without causing a large gap where a passerby falls or a foot fits. .
