Therefore, there are the following problems.
Originally, all the length of nails, screws, etc. is driven into the interior of the wood, increasing the frictional resistance and making it difficult to pull out, so it is desirable to make maximum use of the strength against the load. A nail, a screw, or the like driven into the outer wall material is detached because the small end (the narrow surface in the longitudinal direction) of the middle column of the panel is narrow, and penetrates the plywood material and protrudes into the middle space portion of the wall panel.
However, in recent years, working with electric tools and tools using compressed air has been carried out, so there is no reaction even if nails and screws are removed, and they have been exposed to wind and rain and direct sunlight for many years. Decreasing watertightness of water treatment coking materials causes warping and distortion in the outer wall material, opening gaps, and intrusion of rainwater may cause off-wall corrosion, mold, etc. There was a problem that a decrease in waterproofness and a lack of strength were often pointed out.
The present invention has been made to solve these problems.
