Description

  The present invention relates to an expandable joint cover device that covers a gap that is interposed as a joint between each frame of two adjacent buildings.

  A typical prior art is disclosed in Patent Document 1, for example. In this prior art, even if each frame of two adjacent buildings is displaced in a direction approaching or separating from each other due to an earthquake or the like, the displacement is allowed and the state in which the space between the frames is covered is maintained. In addition, the present invention proposes an expandable joint cover device that includes a joint cover body that is mounted between the housings, one end portion is locked to one housing, and the other end portion is movably supported by the other housing.

  The joint cover body is realized by so-called grating in which a plurality of bearing bars made of steel or stainless steel and a plurality of under bars are connected in a lattice form according to an explicit theory.

  Therefore, when laying a plurality of joint cover bodies in alignment with the extending direction in which the gap extends across the housings, the horizontal cover is installed at the end in the extending direction more than the width of the joint cover body in the extending direction. In the case where the width is short, as joint joints arranged at the end in the extending direction, different joint cover bodies having different width dimensions in the extending direction of the remaining joint covers are provided with different numbers of installation widths. However, there is a problem that the number of types of joint cover bodies increases.
