Description

[Technical Field]

[0001] The present invention relates to a joint covering device. [Background technology]

[0002] 13 to 15 of Patent Document 1 discloses a joint cover device having a shielding member that extends from one adjacent building to the other building to cover the joint between the two buildings, a cover that extends from the other building to the first building below the shielding member, and a pivotable support member located directly below the cover. The pivotable support member has a horizontal support rod at its top and is connected to the side wall surface of the other building so as to be pivotable horizontally, and is normally held in a position protruding diagonally forward from the side wall surface of the other building by the biasing force of a biasing means.

[0003] Each pivotable support member is provided with a pressed end. The pressed end protrudes forward from the tip of the support rod below the support rod and can abut against the side wall surface of the other building. As the joint width narrows during an earthquake, the pressed end is pressed against the side wall surface of one building, causing each pivotable support member to rotate toward the other building, and the cover hangs downward sequentially from the tip side. This prevents the cover from colliding with the side wall surface of the other building.

[0004] In the event that the joint width widens significantly during an earthquake, the free end of the shielding member is supported by a cover, and the area of ​​the joint that cannot be covered by the shielding member is also covered by the cover. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Patent No. 5231971 [Patent Document 2] Patent No. 6322515 Summary of the Invention [Problem to be solved by the invention]

[0006] In the conventional examples described in Patent Documents 1 and 2, if there is an intersection where joints meet around the other building, and if one of the buildings moves diagonally relative to the joint during an earthquake, causing the joint at the intersection to widen significantly, depending on the dimensions of the shielding member and cover, a gap may appear at the intersection that is not covered by either the shielding member or the cover.

[0007] An object of the present invention is to provide a joint cover device that can cover gaps between covers that occur at the intersections of joints while ensuring the operation of the covers. [Means for solving the problem]

[0008] The joint cover device of the first aspect comprises a shielding member that is extended from one adjacent building to the other adjacent building via a joint and covers the joint; a cover that is extended from the other building to the one building below the shielding member and covers the joint; a support member that is provided on the side wall surface of the other building and is biased to support the cover in an extended state in an overhanging state protruding toward the one building, and when pressed against the one building, the overhang toward the one building is reduced, putting the cover in a hanging state; and a gap filling member that is biased to protrude from the end of the cover in the direction of the joint where the cover is provided at the intersection where the joints extending in two directions intersect, and covers the gap at the intersection of the joint that cannot be covered by the shielding member and the cover, and is pushed into the inside of the cover when pressed against the opposing building.

[0009] This joint cover device covers the joint with a shielding member that extends from one adjacent building to the other adjacent building across the joint, and a cover that extends from the other building to the first adjacent building below the shielding member. The cover is supported by a support member and is in an extended state. The support member is provided on the side wall surface of the other building and is normally biased to extend toward the first building. When the support member is pressed against the first building, the extension toward the first building decreases, causing the cover to hang down.

[0010] At an intersection where joints extending in two directions intersect, if one of the structures moves diagonally relative to the joint during an earthquake, causing the joint at the intersection to widen significantly, a gap may form at the intersection that is not covered by either the shielding member or the cover. With this joint cover device, the biased gap filling member protrudes from the end of the cover in the direction of the joint where the cover is installed, thereby preventing the formation of such a gap.

[0011] Furthermore, when the gap filling member is pressed against one of the opposing structures, it is pushed into the cover, thereby suppressing interference between the structure and the cover. If the cover were to be expanded to provide an enlarged section to prevent gaps from forming, interference would occur between the enlarged section and the one of the structures during an earthquake. By replacing this enlarged section with a gap filling member that moves in and out of the cover, it is possible to both suppress the formation of gaps and prevent interference between the cover and the one of the structures.

[0012] In a second aspect, in the joint cover device of the first aspect, the gap filling members are respectively provided at the ends of the two covers adjacent to each other at the intersection, and when the covers adjacent to each other at the intersection are respectively in an extended state, the adjacent gap filling members are closely opposed to each other.

[0013] In this joint cover device, when adjacent covers at an intersection are extended, adjacent gap filling members face each other closely, allowing for more dense coverage of gaps that occur at the intersection of joints.

[0014] A third aspect is a joint covering device according to the first or second aspect, which has two adjacent shielding members at an inside corner of one of the buildings and two adjacent covers at an outside corner of the other building, and the gap filling member is configured to cover the gap formed between the ends of the two shielding members facing the other building and the ends of the two covers.

[0015] In this joint covering device, the gap formed between the end portions of the two shielding members on the other building side and the end portions of the two covers can be covered with the gap filling member.

[0016] A fourth aspect is a joint cover device according to any one of the first to third aspects, wherein the cover has a hollow portion, and the gap filling member is configured to be forced from inside the hollow portion to enter and exit the hollow portion.

[0017] In this joint cover device, the gap filler is biased from inside the hollow portion of the cover to move in and out of the hollow portion. Therefore, compared to when the gap filler is placed outside the cover, interference between the gap filler and surrounding parts can be reduced and an increase in the thickness of the cover can also be reduced.

[0018] A fifth aspect is a joint cover device according to the fourth aspect, wherein the cover is formed by connecting a plurality of cover elements extending in the direction of the joint, and the hollow portion is provided in the cover elements.

[0019] In this joint cover device, the cover is made up of multiple connected cover elements, and the gap filler is biased from inside the hollow portion of the cover element to move in and out of the hollow portion. This increases the degree of freedom in arranging the gap filler, and allows the gap filler to be appropriately positioned depending on the range of the gap that is not covered by either the shielding member or the cover. [Effects of the Invention]

[0020] According to the present invention, in the joint covering device, it is possible to cover the gap between the covers that occurs at the intersection of the joints while ensuring the operation of the covers. [Brief explanation of the drawings]

[0022] Hereinafter, embodiments of the present invention will be described with reference to the drawings. Components indicated by the same reference numerals in each drawing are the same or similar components. Note that duplicated descriptions and reference numerals may be omitted in the embodiments described below. Furthermore, all drawings used in the following description are schematic, and the dimensional relationships and ratios of elements shown in the drawings do not necessarily correspond to the actual ones. Furthermore, the dimensional relationships and ratios of elements between multiple drawings do not necessarily correspond to the actual ones.

[0023] 1 to 3, a joint covering device 10 according to this embodiment is installed in a joint 16 between two adjacent buildings 12 and 14. The first building 12 is a building with a seismic isolation structure, the lower part of which is supported by a seismic isolation device (not shown), for example. The joint 16 is formed with a predetermined width along the periphery of the first building 12, and is designed to absorb relative horizontal shaking between the first building 12 and its surrounding building (the second building 14) during an earthquake.

[0024] The joint covering device 10 according to this embodiment includes a shielding member 26, a cover 34, a plurality of pivotable support members 36 as an example of a support member, and a gap filling member 20.

[0025] (Shielding member) As shown in Figure 3(A), a sliding receiving frame 24 is disposed on the side edge of the other building 14. At the intersection where the joints 16 extending in two directions intersect at approximately right angles, a shielding member 26 protrudes from the inside corner of one building 12 toward the other building 14.

[0026] The shielding member 26 is formed in the shape of a flat rectangle with a predetermined thickness that matches the depth of the sliding receiving frame 24, and its base end is swingably connected to the side edge of one of the buildings 12 via connecting means 28. The tip side of the shielding member 26 is a free end, and an end shielding plate 30 that can swing slightly up and down is provided to protrude from the outer end of this free end.

[0027] 3(A), the shielding member 26 is extended from one building 12 to the other building 14, covering the joint 16, and its free end is slidably mounted on the sliding receiving frame 24. The upper side of the operating gap 32 formed between the free end and the sliding receiving frame 24 is shielded by the end shielding plate 30. Note that "normal" means that the rotating support member 36, which will be described later, is in its restored state.

[0028] (cover) 1 to 3, cover 34 is a member that extends from one building 14 toward the other adjacent building 12 across joint 16, covering joint 16. Cover 34 extends in a direction along joint 16 and is supported from below by a pivotal support member 36. Cover 34 includes a divided cover plate 34A located at the base end and multiple divided cover plates 34B, and with divided cover plates 34A, 34B aligned in the width direction of joint 16, its overall shape is formed into a substantially flat rectangular plate.

[0029] The ends of adjacent divided cover plates 34B are connected to each other so that they can rotate up and down. The divided cover plate 34A and the divided cover plate 34B adjacent to the divided cover plate 34A are also connected to each other so that they can rotate up and down. The divided cover plate 34A at the base end is attached to the other building 14.

[0030] (rotation support member) In Figures 1, 3(A), 4, and 5, the pivoting support member 36 is provided on the side wall surface 14A of the other building 14, and is biased to support the cover 34 in an extended state in a protruding state toward one of the buildings 12, and when pressed against one of the buildings 12, the protrusion toward one of the buildings 12 decreases, causing the cover 34 to hang down.

[0031] In this embodiment, two pivotal support members 36 are used for one cover 34. The pivotal support members 36 are pivotally supported on first fulcrums 41 provided on the side wall surface 14A of the other building 14, allowing them to pivot horizontally. In other words, one first fulcrum 41 is provided for one pivotal support member 36. The first fulcrum 41 is provided on a mounting frame 48 fixed to the side wall surface 14A.

[0032] Each of the multiple pivot support members 36 includes an upper edge portion 36A that supports the cover 34. Each pivot support member 36 is formed into a substantially rectangular frame shape by the upper edge portion 36A, a front frame portion 36B, a shaft portion 36C, and a lower frame portion 36D. The upper edge portion 36A and the front frame portion 36B are integrally formed, for example, by bending a round pipe into an L-shape. The front frame portion 36B extends downward from the tip of the upper edge portion 36A via a curved portion 36E. The shaft portion 36C is connected to the base end of the upper edge portion 36A, extends vertically, and is pivotally supported by a first fulcrum 41. The lower frame portion 36D extends substantially horizontally and connects the lower end of the shaft portion 36C to the front frame portion 36B. The first fulcrum 41 pivotally supports the upper and lower ends of the shaft portion 36C.

[0033] The second fulcrums 42 provided at the tip ends of the pivotal support members 36 are pivotally connected to each other by a connecting member 44, thereby forming a parallel link mechanism 46. The connecting member 44 is provided below the lower frame portion 36D on an extension of the front frame portion 36B. The connecting member 44 also extends horizontally and is disposed parallel to the side wall surface 14A of the other building 14 in a plan view.

[0034] A roller 40 serving as a pressing member is provided on one of the buildings 12 at a position facing at least the connecting member 44, for example, on the side wall surface 12A. When one of the buildings 12 approaches the other building 14 relatively, the roller 40 presses the connecting member 44. When the roller 40 is in contact with the connecting member 44, the roller 40 rolls on the connecting member 44 in response to relative displacement between the connecting member 44 and the rotating support member 36 due to rotation of the connecting member 44. When the roller 40 is separated from the connecting member 44, the pair of rotating support members 36 are inclined in the same direction and at the same angle relative to the side wall surface 14A in a plan view. When the roller 40 presses the connecting member 44, a moment is generated in a direction in which the rotating support member 36 folds.

[0035] 3(A), the height position of the upper side 36A of the pivot support member 36 may decrease from the first fulcrum 41 side toward the second fulcrum 42 side. In the example shown, the upper side 36A is linearly inclined downward from the first fulcrum 41 side toward the second fulcrum 42 side. This ensures space for the cover 34 in the restored state to move upward.

[0036] The pivot support member 36 has a middle frame 72. The middle frame 72 vertically connects the middle portion of the upper side portion 36A and the middle portion of the lower frame portion 36D, reinforcing the pivot support member 36. In other words, the middle frame 72 is a type of reinforcing member. A spring retainer 64 is attached to the middle frame 72. A plurality of tension springs 38 are stretched between the spring retainer 64 and the mounting frame 48. When the pivot support member 36 is in the restored state, the tension springs 38 are stretched to a certain extent compared to their free state, constantly biasing the pivot support member 36. This prevents unnecessary movement of the pivot support member 36.

[0037] (Return assist device) 4 and 5, the connecting member 44 may be provided with a return assist device 74. The return assist device 74 has an assisting rotation member 76 and a tension spring 78.

[0038] The auxiliary rotation members 76 are, for example, a pair of angle bars that are pivotally supported by the connecting member 44 to be horizontally rotatable and that extend toward the other building 14. Each auxiliary rotation member 76 is rotatably attached to the upper and lower surfaces of the connecting member 44. A roller 80 is rotatably supported at the tip of the auxiliary rotation member 76. The axial direction of the roller 80 is the up-down direction (vertical direction). The outer circumferential surface of the roller 80 is attached so as to protrude beyond the tip of the auxiliary rotation member 76 toward the other building 14, regardless of the angular position of the auxiliary rotation member 76.

[0039] When the rollers 80 are separated from the side wall surface 14A of the other building 14, the pair of auxiliary rotation members 76 are inclined in the same direction and at the same angle relative to the connecting member 44 in a plan view. When the side wall surface 14A presses against the rollers 80, a moment is generated in the direction in which the auxiliary rotation members 76 are folded toward the connecting member 44.

[0040] The tension spring 78 is stretched between the tip of the auxiliary rotation member 76 and the connecting member 44, and is a member that rotates the auxiliary rotation member 76 in a direction in which the tip (roller 80) of the auxiliary rotation member 76 moves away from the connecting member 44. When the auxiliary rotation member 76 is in the return state, the tension spring 78 is stretched to a certain extent compared to its free state, and constantly urges the auxiliary rotation member 76. This prevents unnecessary movement of the auxiliary rotation member 76.

[0041] (Gap filling material) 1 and 2, the gap filling member 20 is a member that is biased to protrude from the end of the cover 34 toward the joint 16 where the cover 34 is installed at the intersection where the joints 16 extending in two directions intersect. The gap filling member 20 is also a member that covers the gap S at the intersection of the joints 16 that cannot be covered by the shielding member 26 and the cover 34. The shielding member 26 protrudes from the inside corner of one building 12 to the outside corner of the other building 14. If the joint 16 widens significantly, a gap S will be formed between the end (end shielding plate 30) of two adjacent shielding members 26 at the inside corner of one building 12, which is on the side of the other building 14, and the end of two adjacent covers 34 at the outside corner of the other building 14. This gap S corresponds to the hatched area in FIG. 14.

[0042] The cover 34 is configured by connecting split cover plates 34A, 34B as multiple cover elements extending in the direction of the joints 16. Each of the split cover plates 34A, 34B has a hollow portion 34C. In this embodiment, the split cover plates 34A, 34B are configured to be hollow as a whole, but the hollow portion 34C may be provided in only a portion of the split cover plates 34A, 34B.

[0043] 2 and 8, the gap filling members 20 are configured to be biased from the inside of the hollow portions 34C of, for example, three divided cover plates 34B, and to move in and out of the hollow portions 34C. Specifically, in FIG. 6, a base 50 to which a guide shaft 52 is fixed is housed in the hollow portions 34C of the divided cover plates 34B. The bases 50 are, for example, pipes, and are fixed to the divided cover plates 34B with screws. The gap filling members 20 are, for example, configured by fixing angle bars 56 to both side surfaces of a square pipe 54, and are inserted into the hollow portions 34C.

[0044] The guide shaft 52 is, for example, a round pipe, and is inserted inside the square pipe 54 of the gap filling member 20. A compression spring 58 is provided between the gap filling member 20 and the base 50. The gap filling member 20 is biased by the compression spring 58 in a direction that causes it to protrude from the end of the divided cover plate 34B. Furthermore, when the gap filling member 20 is pressed against one of the opposing structures 12, it is pushed into the cover 34.

[0045] The tip of the guide shaft 52 extends, for example, to near the end of the cover plate 34B, but does not protrude from the hollow portion 34C. In this embodiment, the length of the guide shaft 52 provided on each of the three divided cover plates 34B is the same. The length of the guide shaft 52 is set so as to allow all of the gap filling members 20 with the longest stroke to be pressed into the cover plate 34B (FIG. 2).

[0046] 3(B), 6 and 7, the end of the cover plate 34B is provided with, for example, two stoppers 60 that restrict the amount of protrusion of the gap filling member 20. The angle members 56 on both sides are each provided with a hook portion 56A that engages with the stoppers 60. When the gap filling member 20 protrudes to a predetermined amount, the hook portion 56A abuts against the stopper 60, restricting the gap filling member 20 from protruding any further.

[0047] As shown in Fig. 2, the gap filling members 20 are provided at the ends of two adjacent covers 34 at the intersection of the joint 16, for example. When the adjacent covers 34 at the intersection of the joint 16 are in the extended state, the adjacent gap filling members 20 protrude from the ends of the covers 34 and are arranged to closely face each other, for example, in a diagonal direction (line X) of the intersection. The tips of the gap filling members 20 are formed along the diagonal direction (line X) so that they closely face each other in the diagonal direction (line X). In other words, the tips of the gap filling members 20 are inclined with respect to the direction in which the gap filling members 20 expand and contract.

[0048] The gap filling members 20 may be arranged to face each other in a staggered manner, as in Modification 1 shown in Fig. 15. Furthermore, as in Modification 2 shown in Fig. 16, the gap filling members 20 may be configured to protrude from the end of only one of two covers 34 that are adjacent to each other at the intersection of the joint 16.

[0049] (action) This embodiment is configured as described above, and its operation will be described below. In this embodiment, the joint 16 can be covered by a shielding member 26 extending from one adjacent building 12 toward the other adjacent building 14 via the joint 16, and a cover 34 extending from the other adjacent building 14 toward the one adjacent building 12 below the shielding member 26. The cover 34 is supported by a pivotable support member 36 and is in a protruding state (FIG. 3(A)). The pivotable support member 36 is provided on the side wall surface 14A of the other adjacent building 14, and its tip is biased in a direction that protrudes toward the one adjacent building 12, and is normally in a protruding state. Furthermore, when the tip of the pivotable support member 36 is pressed against the one adjacent building 12, the protrusion toward the one adjacent building 12 decreases, causing the cover 34 to hang down (FIG. 13(A)).

[0050] 14, at an intersection where joints 16 extending in two directions intersect, if one of the structures 12 moves in a diagonal direction (in the direction of arrow A) relative to the joint 16 during an earthquake and the joint 16 at the intersection widens significantly, a gap S may be created at the intersection that is not covered by either the shielding member 26 or the cover 34. In this embodiment, the biased gap filling member 20 protrudes from the end of the cover 34 in the direction of the joint 16 where the cover 34 is provided, and the formation of such a gap S can be suppressed.

[0051] The gap filling member 20 moves in and out of the hollow portion 34C of the cover 34 by being biased from inside the hollow portion 34C of the cover 34. Therefore, compared to when the gap filling member 20 is disposed outside the cover 34, interference between the gap filling member 20 and surrounding parts can be reduced, and an increase in the thickness of the cover 34 can also be reduced.

[0052] Furthermore, the cover 34 is configured by connecting multiple cover elements (divided cover plates 34A, 34B), and the gap filling member 20 is biased from inside the hollow portion 34C of the divided cover plate 34B to move in and out of the hollow portion 34C (FIGS. 6 and 8). This increases the degree of freedom in arranging the gap filling member 20, and allows the gap filling member 20 to be appropriately positioned depending on the range of the gap S that is not covered by either the shielding member 26 or the cover 34.

[0053] In this embodiment, when adjacent covers 34 at the intersection are each in a protruding state, adjacent gap filling members 20 face each other closely, so that the gap S occurring at the intersection of the joints 16 can be covered more densely.

[0054] 9 and 10, when one building 12 and the other building 14 come close to a certain extent in the diagonal direction (the direction of line X) of the intersection of joint 16, joint 16 is covered by shielding member 26, and cover 34 is also covered by shielding member 26, so the above-mentioned gap S does not occur. Although the ends of covers 34 of each gap filling member 20 protrude, they are not exposed upward because they are covered by shielding member 26.

[0055] In Figure 11, if an earthquake causes the other building 14 to displace, for example, in the direction of arrow B and approach the one building 12, the rollers 40 come into contact with the connecting members 44, pressing the connecting members 44 and displacing them toward the side wall surface 14A of the other building 14. Because the connecting members 44 and the pivoting support members 36 form a parallel link mechanism 46, the displacement of the connecting members 44 causes the multiple pivoting support members 36 to pivot horizontally and synchronously toward the side wall surface 14A of the other building 14 against the biasing force of the tension springs 38 and fold. At this time, the rollers 40 roll on the connecting members 44 in contact with them as they are displaced relative to the connecting members 44 by the rotation of the pivoting support members 36. At this time, the rollers 80 of the return assist device 74 are pressed against the side wall surface 14A of the other building 14, causing the auxiliary pivoting members 76 to also fold.

[0056] 11 to 13, as the pivotal support member 36 pivots horizontally and folds, the cover 34 hangs down smoothly. This prevents the cover 34 from colliding with one of the buildings 12. At this time, the shielding member 26 rides up onto the sliding receiving frame 24. When the tip of the gap filling member 20 is pressed against the opposing building 12, it is pushed into the cover 34, thereby preventing interference between the building 12 and the cover 34. If the cover 34 were expanded to provide an enlarged portion without using the gap filling member 20 to prevent the formation of the gap S, interference would occur between the enlarged portion and the building 12 during an earthquake. By replacing this enlarged portion with the gap filling member 20 that extends and retracts from the cover 34, it is possible to both prevent the formation of the gap S and prevent interference between the cover 34 and the building 12.

[0057] When the first building 12 and the second building 14 move apart, the pivoting support members 36 pivot synchronously due to the biasing force of the tension springs 38, protruding toward the first building 12 ( FIG. 3(A) ). Accordingly, the cover 34 is smoothly lifted by the pivoting support members 36 and projected from the second building 14 toward the first building 12. When the pivoting support members 36 begin to return, the auxiliary pivoting members 76 also begin to return due to the biasing force of the tension springs 78. The return of the auxiliary pivoting members 76 facilitates the return of the pivoting support members 36. As a result, even if the joint 16 is wide and the cover 34 is relatively long and heavy, the hanging cover 34 can be lifted and projected toward the first building 12 when the pivoting support members 36 are folded. Therefore, the return assisting device 74 is suitable for a structure in which the joint 16 is relatively wide. When the joint 16 is relatively narrow, the return assisting device 74 may be omitted.

[0058] As described above, according to this embodiment, the joint covering device 10 can cover the gaps S between the covers 34 that occur at the intersections of the joints 16 while ensuring the operation of the covers 34. This makes it possible to provide an improved joint covering device 10.
