Description

  The present invention relates to a wall substructure.

  Conventionally, since an outer wall material such as reinforced concrete and a metal fixing member such as an anchor bolt embedded in the outer wall material have almost the same linear expansion coefficient, no countermeasures by thermal expansion and contraction have been taken.

  However, recently, there is a configuration in which a metal body edge is fixed to the outside of an outer wall material such as concrete by a fixing means for fixing the body edge (see, for example, Patent Document 1).

JP 2004-251031 A

  However, when the trunk edge is disposed outside the outer wall material as in Patent Document 1 described above, the trunk edge has a smaller heat capacity than the outer wall material, and thus is easily affected by heat.

  Due to recent typhoons, even in relatively large buildings where the effects of thermal expansion and contraction are likely to occur, the difference in thermal expansion and contraction between the outer structure and the inner structure was not necessarily taken into account in terms of the fixing method. It was found that when the outer structure dropped out, it was discovered that the fixing means and the surrounding area were damaged by thermal expansion and contraction of the trunk edge. For this reason, if the outer edge of the shell is thermally expanded and contracted, the outer wall material may be damaged if the outer wall is a hard material such as concrete, or the outer wall may be soft, such as ALC (lightweight cellular concrete). In the case of this material, there is a possibility that the fixing means for the trunk edge may damage the outer wall material.

  The present invention solves the above-described problems, and an object thereof is to stabilize the trunk edge even when the trunk edge is thermally expanded and contracted in a configuration in which the trunk edge is disposed outside the outer wall material. It is intended to provide a substructure of the wall that can be held.

In order to achieve the above object, the lower structure of the wall according to the present invention includes a body edge on which a guide portion is formed in the longitudinal direction and a holding portion on which the guide portion is slidably held in the longitudinal direction. A body edge fixing tool having a member and a fixing means for fixing the holding member to the wall surface, the fixing means being fixed to the wall surface, and the holding member being fixed to the fixing means by screws. it, as the guide portion of the furring strip is slidable along the grip portion, the barrel edge is fixed relative to the wall surface, the overhang is provided on the lower portion of the wall to the barrel edge drained The board is fixed, The exterior material arrange | positioned on the outer side of the said overhanging draining board was fixed to the said trunk edge, It is characterized by the above-mentioned.

  The wall lower structure according to the present invention is a wall lower structure in which the trunk edge is disposed outside the outer wall material, and the trunk edge is stably held even when the trunk edge is thermally expanded and contracted. It is possible to stably support the overhanging drainage plate that is fixed to the trunk edge and is provided at the lower part of the wall and the exterior material that is disposed outside the overhanging drainage board and is fixed to the trunk edge.
