Description

[Technical field]

[0001] The present invention relates to a joint cover device that covers a joint between wall surfaces of left and right frameworks via a joint, and a joint cover support device used in this joint cover device. [Background technology]

[0002] A known example of a conventional wall joint device is a wall joint cover device that includes at least two or more telescopic link mechanisms having three central pivot parts in the center, both ends of which are pivotally supported on the outer wall surfaces of the joint parts of the left and right buildings provided through the joint parts, U-shaped cover plates that are open on the left and right building sides and are pivoted to the central pivot parts on both sides of these telescopic link mechanisms with pivot pins fixed to the center of the inner plate, end cover plates that are pivotally supported on the pivot parts at both ends of the telescopic link mechanisms and have their tips inserted into the interior by sliding to come into contact with the outer plate of the cover plate, and a central cover plate whose both ends pivoted to the central pivot part at the center of the telescopic link mechanism overlap with the outer plate of the cover plate and can slide'' (Patent Document 1).

[0003] However, in such a wall joint device, even if multiple expansion link mechanisms are provided in the vertical direction to prevent deflection of the cover plate and mounting members, if the left-right dimension of the joint is also large, the central portion of the expansion link mechanism having multiple link parts will bend and displace downward, and since each of the multiple pivot parts in such an expansion link mechanism bends, even if multiple expansion link mechanisms are provided in the vertical direction, it is difficult to prevent deflection in the front-back direction due to strong winds, etc.

[0004] On the other hand, in an extension link mechanism having only one link portion and multiple pivot points provided on this one link portion, the dimensions of the link portion become large, making it difficult to provide multiple extension link mechanisms in the vertical direction.

Effect of the Invention

[0015] As is clear from the above description, the present invention provides the following effects. (1) In each of the inventions described in claims 1 and 4, a first telescopic link mechanism and a second telescopic link mechanism are used, so that the load applied to the joint cover, etc. when the joint cover, etc. is installed can be efficiently distributed. Therefore, even when subjected to a load such as strong wind, the load can be dispersed and damage to the joint cover support device, etc. can be prevented. (2) Furthermore, the use of these telescopic link mechanisms makes it possible to safely absorb shaking caused by earthquakes. (3) Since the first telescopic link mechanism, which is generally triangular or inverted triangular in shape, and the second telescopic link mechanism, which is horizontally elongated, are used in combination, the length by which the telescopic link mechanism extends in the vertical direction can be reduced even when the joint portion is narrower than when a telescopic link mechanism having a generally diamond shape is used. Therefore, a large number of telescopic link mechanisms can be attached, the load can be better distributed, and by using these telescopic link mechanisms in combination, the area supported by the telescopic link mechanisms is increased, making it possible to withstand wind pressure caused by strong winds. (4) In the inventions recited in claims 2 and 5, the same effects as those in (1) to (3) can be obtained, and the strength of the second telescopic link mechanism can be improved, allowing it to withstand a larger load. (5) The inventions described in claims 3 and 6 can obtain the same effects as those described in (1) to (4) above, and by further providing an extendable arm mechanism, the load can be further distributed and the strength can be improved.

[0017] The present invention will be described in detail below with reference to the embodiments shown in the drawings. In this specification, the left-right direction, the top (top of the drawing) and the bottom (bottom of the drawing) directions are based on Fig. 5. The front (bottom of the drawing) and rear (top of the drawing) directions are based on Fig. 6.

[0018] In addition, in the present invention, the term "structure" refers to a structure such as a building, road, slab, elevator shaft, etc. in which a joint plate can be installed, and the term "entrance / exit" refers not only to an entrance / exit with a door or gate, but also to a passageway through which people, vehicles, etc. can pass.

[0019] In the first form for implementing the present invention shown in Figures 1 to 9, 1 is a joint cover support device that supports a joint cover device X (e.g., Figure 5) that covers a joint 2 between one structure 3 and the other structure 4.

[0020] As shown in FIG. 1, this joint cover support device 1 includes one or more first telescopic link mechanisms 7 each having one end attached to the one frame 3 and the other end on the opposite side attached to the other frame 4, and being interposed between the frames and having a plurality of first pivot parts 6 that do not displace in the vertical direction; and a second telescopic link mechanism 7 each having one end attached to the one frame 3 and the other end on the opposite side attached to the other frame 4, and being interposed between the frames in the same manner as the first telescopic link mechanism 7. The telescopic link mechanism 9 is made up of one or more second telescopic link mechanisms 9 having a plurality of second pivot parts 8 that do not move in the vertical direction, a plurality of long rod-shaped mounting members 10 that are pivotally supported by the first pivot part 6 and the second pivot part 8, respectively, and to which a joint cover 21 (e.g., Figure 7) can be attached, and an telescopic arm mechanism 11 (e.g., Figure 4) having one end attached to one of the bodies 3 and the other end attached to the other body 4, and having a support member 17 connected to at least one of the mounting members 10.

[0021] The first telescopic link mechanism 7 is attached to the one body 3 or the other body 4, and is composed of a pair of first long links 12 whose protruding ends are connected to each other so as to form an upwardly or downwardly convex shape in a front view, and a plurality of first link members 13 each pivotally supported by the first long link 12 and connected in a pivoted state so that their lower or upper ends become first pivot parts 6, and is formed into a substantially triangular or substantially inverted triangular shape as a whole. Note that, with reference to Fig. 2, a large number (e.g., seven) of first pivot parts 6 are positioned on substantially the same horizontal line at a predetermined interval.

[0022] When the first long link 12 is connected in an upward convex shape as viewed from the front, the pivot parts at the lower ends of the first long link 12 and the first link material 13 become the first pivot parts 6, and when the first long link 12 is connected in a downward convex shape as viewed from the front, the pivot parts at the upper ends of the first long link 12 and the first link material 13 become the first pivot parts 6.

[0023] The first pivot portions 6 in the embodiment preferably also include pivot portions on one end side of the first long link 12, and these first pivot portions 6 are provided in positions that do not displace in the vertical direction even when the first telescopic link mechanism 7 telescopes in the horizontal direction.

[0024] A plurality of first telescopic link mechanisms 7 may be provided at predetermined intervals in the vertical direction, as shown in FIG.

[0025] As shown in FIG. 3, the second telescopic link mechanism 9 is composed of a number of second link members 14, one end of which is attached to one body 3 and the other end of which is attached to the other body 4, and which are connected in a roughly pantograph shape as a whole.

[0026] This second telescopic link mechanism 9 may be a simple pantograph-like mechanism in which substantially square-shaped link portions 15 are arranged in a substantially straight line in the left-right direction, but in this embodiment, it is composed of a large number of substantially square-shaped link portions 15 arranged in a substantially straight line in the left-right direction and reinforcing link portions 16 formed between adjacent substantially square-shaped link portions 15. Such a mechanism is also included in the link mechanism of the present invention composed of second link members 14 connected in a substantially pantograph shape.

[0027] In this embodiment, the reinforcing link portion 16 is configured by extending the second link material 14 forming the link portion 15 upward or downward and connecting its ends to share two sides with the link portion. By further providing such a reinforcing link portion 16, the strength of the second telescopic link mechanism 9 against deflection in the forward and backward directions can be improved.

[0028] These first pivot parts 6 and second pivot parts 8 are arranged so as to form a straight line in the up-down direction (vertical direction) as shown in Fig. 1, for example, and a mounting member 10 is pivotally supported by the first pivot parts 6 and second pivot parts 8 which are aligned in the up-down direction. It is preferable to configure the number of first pivot parts 6 and second pivot parts 8 to be the same. By configuring in this way, even if the width of the joint part 2 changes, the first pivot parts 6 and second pivot parts 8 are positioned so as to form a straight line in the vertical direction, and it is possible to prevent the mounting member 10 from tilting.

[0029] In this embodiment, the mounting member 10 is a rod-shaped or bar-shaped member, and is in a substantially vertical state when pivoted to the first pivot part 6 and the second pivot part 8. Although a bar-shaped mounting member 10 is used in this embodiment, any shape of mounting member 10 may be used as long as it can attach the joint cover to the pivot parts 6 and 8.

[0030] As shown in Fig. 4, the telescopic arm mechanism 11 is composed of one arm member 18, one end of which (left side in Fig. 4) is attached to one of the frames 3 and the protruding end is inserted into the case-like support member 17 with both ends open, the other arm member 19, one end of which (right side in Fig. 4) is attached to the other frame 4 and the protruding end is inserted into the case-like support member 17, and the support member 17 connected to at least one of the many mounting members 10, the mounting member 10 located at the approximate center of the joint portion 2. In the embodiment, the case-like support member 17 with both ends open is fixed to the mounting member 10 at the approximate center, and the load applied to the mounting member 10 can be supported by the left and right frames by the arm members 18 and 19, and the provision of such a telescopic arm mechanism 11 can further distribute the load. In addition, when connecting multiple mounting members 10 and support members 17, it is preferable to connect them via a rail or the like so as not to hinder the sliding of the mounting member 10 in the left and right direction.

[0031] The support member 17 is formed to a size that will not collide with the left and right frameworks 3, 4 even if the joint portion 2 becomes narrower due to an earthquake.

[0032] In this embodiment, the support member 17 has two arm member insertion holes in the vertical direction, and one arm member 18 and the other arm member 19 are inserted into the arm insertion holes 20. These arm members 18, 19 are formed to have dimensions that do not fall off the support member 17 even if the joint portion 2 widens due to an earthquake, and do not collide with the opposing bodies 3, 4 if the joint portion 2 narrows. The arm members 18, 19 and the support member 17 may be provided with a fall prevention means that prevents the arm members 18, 19 from falling off the support member 17.

[0033] The first telescopic link mechanism 7, the second telescopic link mechanism 9, and the telescopic arm mechanism 11 are attached to the left and right frames 3, 4 via hinge members, respectively. At least one of the first telescopic link mechanism 7, the second telescopic link mechanism 9, and the telescopic arm mechanism 11 are provided at a predetermined interval in the vertical direction, and the number of each may be one or more, and the orientation of the first telescopic link mechanism 7 (triangular or inverted triangular) can be changed as appropriate. It is desirable that the first pivot part 6 of the first telescopic link mechanism 7, the second pivot part 8 of the second telescopic link mechanism 9, and the center of the support member 17 of the telescopic arm mechanism 11 are provided so that they can be connected to the mounting member 10 at approximately equal intervals in the vertical direction. By providing the first telescopic link mechanism 7, the second telescopic link mechanism 9, and the telescopic arm mechanism 11 in this manner, the load applied to the joint cover 21 and the mounting member 10 can be evenly distributed.

[0034] Furthermore, in addition to these telescopic link mechanisms 7 and 9 and telescopic arm mechanism 11, other known telescopic link mechanisms may be used in combination. In this embodiment, from the top of Fig. 1, there are provided the telescopic arm mechanism 11, a first telescopic link mechanism with an upward convex shape, the second telescopic link mechanism 9, the telescopic arm mechanism 11, and a first telescopic link mechanism with a downward convex shape. Note that this telescopic arm mechanism 11 does not necessarily have to be provided if the first telescopic link mechanism 7 and the second telescopic link mechanism 9 are capable of supporting a load or the like.

[0035] The joint cover device X of the present invention using such a joint cover support device 1 is composed of the joint cover support device 1 of the present invention having one end attached to one structure and the other end attached to the other structure, as shown in Figures 5 and 6, and a joint cover 21 that is attached to the mounting member 10 of the joint cover support device 1 and covers the joint portion 2.

[0036] As shown in Fig. 7, this joint cover 21 uses a plate-like joint cover 21 formed in a roughly crank shape, one end of which is fixed to the mounting member 10. The other end overlaps with the adjacent joint cover 21, and during an earthquake, the overlap width changes to absorb the shaking caused by the earthquake. Note that the joint cover 21 is not limited to this structure, and for example, a soft, sheet-like joint cover 21 may be used and fixed to the mounting member with some slack in the front-to-rear direction to close the joint.

[0037] When an earthquake causes the left and right frames 3, 4 to shake so that the joint 2 narrows, as shown in Figure 8, the first telescopic link mechanism 7, the second telescopic link mechanism 9 and the telescopic arm mechanism 11 contract in the left-right direction and displace so that the overlap width of adjacent joint covers 21 increases, absorbing the shaking caused by the earthquake.

[0038] When an earthquake causes the left and right bodies 3, 4 to shake so that the joint section 2 widens, as shown in Figure 9, the first telescopic link mechanism 7, the second telescopic link mechanism 9 and the telescopic arm mechanism 11 extend in the left and right directions and displace so that the overlap width of adjacent joint covers 21 becomes smaller, absorbing the shaking caused by the earthquake. [Industrial Applicability]

[0039] The present invention finds application in the industry of manufacturing joint cover devices. [Explanation of symbols]
