Description

  The present invention relates to an architectural board support used when constructing an architectural board such as an outer wall material, an architectural structure of an architectural board using the architectural board support, and an architectural board construction method.

  Patent Document 1 discloses a conventional construction structure of an exterior material. The construction structure of the exterior material described in Patent Document 1 is an outer wall structure in which a plurality of wall materials are constructed in an armor shape. The armored outer wall structure is a structure in which a plurality of wall materials are arranged next to each other in the vertical direction, and a part of the upper wall material of these wall materials is overlapped from the outdoor side of the lower wall material. This is the structure.

  By the way, in general, in order to attach the wall material to the wall foundation in an armored shape, after fixing the lower wall material to the ground, the upper wall material is partially overlapped with the lower wall material on the outdoor side Arrangement is made, and a sticking tool such as a nail is hit against the upper wall material while maintaining this state. At this time, in order to hit the fixing member on the upper wall member, it is necessary to press the upper wall member against the base with a hand or an arm so as not to deviate from the arranged position.

  However, when the size of the wall material is large, it may be difficult to maintain the position because the weight increases. In this case, it is difficult for one person to work, and even if one person works, for example, the wall material is tilted during the work, and the wall material is fixed while tilted. Defects can occur.

  On the other hand, in the construction structure of the armor-like exterior material of Patent Document 1, a support member having an inverted L-shaped cross section is fixed to the indoor surface of the upper wall material with an adhesive or the like. When attaching and installing the upper wall material, the support member is temporarily held by being hooked on the upper end surface of the lower wall material, and in this state, the fixing member is hit against the upper wall material to perform the main fixing.

  As a result, the load on the upper wall material can be supported by the lower wall material, which not only facilitates construction, but also allows the upper wall material to be stably held at a position determined by design. Therefore, it becomes easy to work alone.
