Description

  The present invention relates to a wall fixture, a wall structure, and a method of manufacturing the fixture.

  Conventionally, there exist some which were disclosed by patent documents 1-4 in the fixture of wall material. These attachments are for attaching wall materials to the structure. These fixtures include a fixing portion that can be fixed to the structure, a support portion that is provided at a position protruding from the fixing portion, and a locking portion that is provided so as to protrude from the support portion.

  In the fixtures disclosed in Patent Documents 1 and 2, the protruding distance of the support portion at the position protruding from the fixed portion is relatively short. For this reason, in general, in these fixtures, in order to provide a desired gap between the wall material and the structure, the fixing portion is fixed to the structure with a spacer such as a trunk edge interposed. The On the other hand, in the fixtures disclosed in Patent Documents 3 and 4, the protruding distance of the support portion at the position protruding from the fixed portion is sufficiently long, and the above-described spacer is unnecessary. For this reason, even if a fixing | fixed part is directly fixed to a structure, these fixtures can provide a desired clearance gap between a wall material and a structure.
