Attaching the fittings that support this finishing material involves a second step of incorporating the adjacent finishing materials into the fittings and arranging them, and a second step of placing an iron plate that supports the fittings on the upper end surface of the fittings. and a fourth step of fixing the base frame, the framework of which is composed of vertical and horizontal materials and supporting the finishing material, by interposing the iron plate to the metal fittings.
It is characterized by having a process.

Further, the method for manufacturing a dry curtain wall according to claim (2) is characterized in that, in the first step, finishing materials to which fittings are attached in advance are laid out.

Furthermore, the dry curtain wall manufacturing method according to claim (3) is characterized in that in the first step, the finishing materials are laid out while arranging gap members to ensure joint spacing between the finishing materials.

Further, in the method for manufacturing a dry curtain wall according to claim (4), a framework is constructed by welding the vertical members and the horizontal members onto a steel plate, and during this welding, they are temporarily fixed to each other, causing welding distortion. It is characterized by preventing

Furthermore, the fitting according to claim (5) is characterized in that support legs for transmitting reaction force when fixed to the base frame between the iron plate and the finishing material are arranged on both sides of the fixing means. .

Further, the base frame according to claim [6] is characterized in that the side opposite to the iron plate is open for insertion of a fixing device, since the fixing means for fixing to the fitting is applied.

[Effect]

In the invention of claim (1), the finishing material is laid out on the steel bed. Since this finishing material constitutes the outer wall of the building after being attached to the building, natural stone cut into thick slabs is used for boat fishing. Next, fittings are attached to the ends of the arranged finishing materials, and the finishing materials are successively laid out on the steel bed via these fittings. Accurate spacing can be maintained by placing block-shaped gap members between each finishing material.
