It is fixed to the building frame 1 via. Reference numeral 10 is a synthetic resin foam made of a closed-cell foam structure, which fills the gap between the vertical rims 9 and closes the space formed by the vertical rims 9, the wall 2, and the outer wall material to be described later. The purpose is mainly to provide insulation to the new exterior walls and prevent condensation. Reference numeral 11 is a starter that is fixed horizontally on the mounting part 6 of the foundation drainer 5 , and is mainly used to lock and fit the external wall material 16, and also to prevent wind and rain from entering the lower end of the new wall. be. Its shape consists of an elongated body with a cross section as shown in FIGS. 3a to 3f. That is, figures a to c are suitable for attaching a hook type exterior wall material 16, and figures d to f are a drop type exterior wall material 16. Specifically, we roll-form metal sheets,
It is made up of a nail driving part 12, a bottom part 13, and an engaging part 14 by pressing or the like. 15
This is a new exterior wall in which dry-type exterior wall materials 16 are successively roofed in the horizontal direction.The exterior wall materials 16 have a cross section as shown in FIG. It consists of one type of plate or the like. The connection structure of the outer wall material 16 is either a hook type or a depressed type. 17: Drain the base with nails 5 , Starter 1
