BACKGROUND OF THE INVENTION1. Field of the Invention
The preferred embodiments of the present invention relate to a siding boards attachment structure for securing external walls to a structural body such as a building frame with securing members in a rabbet joint manner.
2. Description of the Related Art
The following description sets forth the inventor's knowledge of related art and problems therein and should not be construed as an admission of knowledge in the prior art.
As shown in
In the aforementioned siding boards attachment structure 9, however, there is a portion where the securing member 95 cannot be used. For example, as shown in
Accordingly, the cut end portion 923 of the size adjusting external wall member 920 is secured to the furring strip 93 horizontally fixed to the structural body 90 by putting in a nail 99 from the surface side. In this state, since the securing member 95 is engaged with the upper side lower-ledge 921 at the upper side of the size adjusting external member 920, a spacer 98 is disposed between the size adjusting external wall member 920 and the furring strip 93 to make the external construction surface flush with each other.
However, the nailing against the size adjusting external wall member 920 causes a deterioration of the appearance. In other words, although the securing members 95 are used to create the excellent appearance of the external wall, nailing is required to secure certain portions where the securing member cannot be used, resulting in deteriorated external appearance.
Furthermore, the nailed portion requires patching coating to improve the external appearance, causing deteriorated construction efficiency, which in turn causes increased construction costs. In addition, the nailing may cause cracks of the external wall member and/or water leakage. Especially, in cases where a hard member such as a fired material is used as the external wall member, the nailing may cause damages such as cracks to the external wall member.
The aforementioned problems may arise not only at an assortment portion connecting with a lower roof, but also at another portions, e.g., an upper or lower side of an opening portion, or an overhang portion, using a size adjusting external wall member.
The description herein of advantages and disadvantages of various features, embodiments, methods, and apparatus disclosed in other publications is in no way intended to limit the present invention. For example, certain features of the preferred embodiments of the invention may be capable of overcoming certain disadvantages and/or providing certain advantages, such as, e.g., disadvantages and/or advantages discussed herein, while retaining some or all of the features, embodiments, methods, and apparatus disclosed therein.
