きる。FIG. 7 shows a modified example of the outer wall material according to the present invention. The outer wall material 1 of the present embodiment has an outer wall base material 2 formed in a horizontally long shape, and an outer surface member 4 divided into two pieces in the longitudinal direction is attached to the outdoor side of the outer wall base material 2. The structure for attaching the outer surface material 4 to the outer wall base material 2 is the same as in the above-described embodiment. A predetermined gap 20 is formed between the adjacent outer surface members 4. A connecting member 21 having a substantially U-shaped cross section made of, for example, an extruded aluminum material is provided on the back surfaces of the outer surface members 4 so as to straddle the gap 20. Has been passed over. When the concrete is poured into the formwork to form the outer wall base material 2, the connecting member 21 removes the concrete from the gap 2 between the outer surface materials 4.
It has a function of preventing leakage from zero. Also,
A seal member 22 is provided between the back surface of the adjacent side edge of the outer surface member 4 and the concave portion of the connecting member 21. In the outer wall member 1 configured as described above, it is preferable that the washer of the stud bolt disposed near the connecting member 21 is fixed to the mounting member 3, and thereby, the outer surface members 4 are provided.
Is restricted in both longitudinal directions of the outer wall substrate 2. Further, in the outer wall material 1, since the outer surface material 4 is divided into a plurality of parts in the longitudinal direction with respect to the laterally long outer wall base material 2, the amount of thermal expansion displacement in the longitudinal direction can be reduced.
