Description

  The present invention relates to a wall surface joint device for covering joint portions between wall surfaces of left and right buildings provided through joint portions.

  Conventionally, a wall joint device has a joint cover in which one end covering the joint is attached to the outer wall of one building and the other end is biased to the outer wall of the other building, and the joint is widened by an earthquake. In this case, a pantograph-shaped telescopic link that supports the joint cover is used.

  This pantograph-shaped expansion / contraction link does not cause a problem when the joint part becomes wide, but when the joint part becomes narrow, even if the pantograph-shaped expansion / contraction link contracts, the link member overlaps and the dimension that cannot be contracted is large. Therefore, there is a drawback that the joint portion has to be set large for the telescopic link.

Japanese Patent No. 3691777

  In view of the conventional drawbacks as described above, the present invention does not prevent the swinging movement even if it is set to a joint dimension that can absorb the shaking movement of the left and right buildings during an earthquake, hardly considering the dimensions of the expansion link when contracted.
