  The present invention relates to a wall joint cover device that covers between outer wall surfaces of left and right buildings provided through joint portions.

2. Description of the Related Art Conventionally, this type of wall joint cover device supports a plurality of slidably overlapping cover plates that cover a joint portion by a pantograph-shaped telescopic link mechanism.
For this reason, even if the expansion / contraction link mechanism expands / contracts, the width dimension of the cover plate must be set so that no gap is generated, the degree of freedom of the setting is low, and the pantograph-shaped expansion / contraction link becomes long and sufficient There was a drawback that a sufficient strength could not be obtained.

  In view of the conventional drawbacks as described above, the present invention uses a telescopic link mechanism that can set the width dimension of the cover plate located on both sides of the central cover plate relatively easily and obtain sufficient strength. An object of the present invention is to provide a wall joint cover device that can be used safely and has sufficient strength.

The above and other objects and novel features of the present invention will become more fully apparent when the following description is read in conjunction with the accompanying drawings.
However, the drawings are for explanation only and do not limit the technical scope of the present invention.

  In order to achieve the above-described object, the present invention provides at least two or more central pivots in the central part where both ends are pivoted on the outer wall surfaces of the joints on the left and right buildings provided via the joints. A telescopic link mechanism, a central cover plate that is pivotally supported by a central pivot portion of at least two or more telescopic link mechanisms, covering a half of the joint portion, both ends of the central cover plate, and the joint portion At least two pairs of both side telescopic link mechanisms having at least one central pivot part pivoted at both ends on the outer wall surface on the side, and a rear end on the central pivot part of the at least two pairs of both side telescopic link mechanisms At least one pair of slide cover plates that are slidably supported on the center cover plate or adjacent to each other, and at least two pairs of both sides of the telescopic link machine A wall joint cover device is constituted by a pair of fixed cover plates whose rear end portions are pivotally supported on the outer wall surface side of the joint portions and whose front end portions are slidably overlapped with the at least one pair of slide cover plates. doing.

As is clear from the above description, the present invention has the following effects.
(1) According to the first aspect of the present invention, it is possible to use a both-side expansion / contraction link mechanism having a smaller expansion / contraction amount than the expansion / contraction amount of the expansion / contraction link mechanism.
Therefore, the movement amount of at least one pair of the slide cover plates that are slid by the both-side telescopic link mechanism can be set small, and the large shaking movement that the joint portion becomes wide or narrow as a whole can be absorbed. .
(2) According to the above (1), the center cover plate is supported by the expansion / contraction link mechanism so as to be located at the center of the joint portion, and the pair of fixed cover plates and the pair of slide cover plates are supported by the both side expansion / contraction link mechanisms. Because it is supported, the load applied to the expansion / contraction link mechanism is increased compared to the conventional one that supports all of the expansion / contraction link mechanism, and the expansion / contraction is weakened by using a large number of square frame links. The link mechanism may not be used.
(3) According to the above (1), the expansion / contraction amount of the both-side expansion / contraction link mechanism may be a dimension between the joint wall side outer wall surface of the left and right buildings and the center cover plate, so that the both-side expansion / contraction link mechanism can be easily set. In addition, the width dimension of the pair of slide cover plates and the pair of fixed cover plates can be easily set so as not to cause a gap.
(4) In claim 2, the same effects as in the above (1) to (3) can be obtained.

  The telescopic link mechanisms 7 and 7 include a rectangular frame-shaped link 17, hinge members 4 and 4 pivotally supported by pivot pins 18 and 18 at both ends of the link 17, and the link 17. The central arm 20 is formed by a central arm 20 having both ends pivotally supported by pivot pins 19, 19 and a central pivot 6 formed at the center of the central arm 20. ing.

  The both-side telescopic link mechanisms 11, 11, 11, 11, 11, 11 are pivoted to a rectangular frame-shaped link 21 smaller than the link 17 of the telescopic link mechanism 7 and pivots 22, 22 at both ends of the link 21. Hinge members 24, 24 pivotally supported by support pins 23, 23, a central arm 26 whose both ends are pivotally supported by pivot pins 25, 25 at the center of opposing arms 21 a, 21 a of the link 21, The central pivot 26 is formed at the center of the central arm 26.

  The wall joint cover device 1 having the above configuration attaches two or more telescopic link mechanisms 7 and 7 to the outer wall surfaces 3a and 3a on the joint portion side.

  At this time, the central cover plate 9 may be attached to the central pivots 6 and 6 of the two or more telescopic link mechanisms 7 and 7 in advance, or attached after the two or more telescopic link mechanisms 7 and 7 are attached. May be.

  Thereafter, three pairs of both side telescopic link mechanisms 11, 11, 11, 11, 11, 11 are attached between the end of the central cover plate 9 and the outer wall surface 3a, 3a on the joint portion side, and the central pivot portion thereof.

  When the joint part 2 becomes wide due to the earthquake, the center cover plate 9 is supported by the two telescopic link mechanisms 7 and 7 so that the center part is located at the center part of the joint part 2 as shown in FIG. Since the pair of both-side telescopic link mechanisms 11, 11, 11, 11, 11, 11 extend, the tip portions of the pair of slide cover plates 14, 14 slide and move toward both ends of the center cover plate 9. The front ends of the fixed cover plates 15 and 15 are also slid toward the rear ends of the pair of slide cover plates 14 and 14 to absorb the shaking motion.

  When the joint portion 2 becomes narrow due to the earthquake, the center cover plate 9 is supported by the two telescopic link mechanisms 7 and 7 so that the center portion is located at the center portion of the joint portion 2 as shown in FIG. Since the pair of both side telescopic link mechanisms 11, 11, 11, 11, 11, 11 contract, the tip portions of the pair of slide cover plates 14, 14 slide and move so that the overlap with the central cover plate 9 increases. The distal ends of the pair of fixed cover plates 15 and 15 are also slid so that the overlap with the pair of slide cover plates 14 and 14 is increased, and the shaking motion is absorbed.

When the left and right buildings 3 and 3 swing in different front and rear directions due to an earthquake, as shown in FIG. 8, the hinge members 4, 4, 4, 4 and 3 pairs of both sides of the two telescopic link mechanisms 7 and 7 expand and contract at both ends. By swinging the hinge members 24, 24, 24, 24, 24, 24, 24, 24, 24, 24, 24, 24 at both ends of the link mechanism 11, 11, 11, 11, 11, 11, the swinging motion is Absorb.
In addition, when the shaking motion of the earthquake stops, it automatically returns to the original state.
