Description

  The present invention relates to a non-land adjustment spacer used when forming an outer wall or the like.

  An outer wall is formed by attaching a plurality of exterior materials to the outdoor side of the wall base in a vertical and horizontal direction. When attaching the external material to the wall base, a plurality of walls are provided on the outdoor side of the wall base. A material fastener is provided, and the exterior material is held on the wall material fastener. However, in the case of a wall surface with a large uneven surface such as a mortar wall, the protruding position of each wall material fastener from the outdoor surface of the wall substrate varies, so the exterior material cannot be held on the wall material fastener. Even if it can be held, there is a problem that a step is generated between the exterior materials, and the smoothness of the outdoor side surface of the outer wall is impaired. Therefore, depending on the size of the unevenness, it is performed to insert a finely cut plywood between the wall base and the wall material fastener, but it is troublesome to cut the plywood each time Further, when the plywood is inserted as it is, there is a problem that the plywood falls if the work is not performed while holding the plywood by hand, so that the work is difficult to perform.

Therefore, it is conceivable to insert a spacer for adjusting the unevenness between the wall base and the wall material fastener, but for example, in Patent Document 1, since the spacer is inserted from the bottom between the wall material and the hardware, A long groove (slit) must be formed in the spacer to prevent it from falling off, and it takes time to manufacture the spacer, or it must be moved to the L shape according to the shape of the long groove when installing the spacer. In other words, there was a problem that it took a lot of work.
