It is accumulated, then flows along the frame member 5 in the longitudinal direction of the frame member 5, and is discharged from the end portion of the frame member 5. Therefore, in the configuration of the present embodiment, the rain stain occurs only below the longitudinal end portion of the frame member 5, so that the rain stain becomes inconspicuous.

In the configuration of FIG. 8, rainwater is discharged using both ends of the frame member 5 in the longitudinal direction as discharge ports. Similarly, it is possible to set the location where the rain stain occurs to a desired position. Therefore, also in the present embodiment, the end portion of the frame member 5 may be separated from the one side wall surface 2b to serve as the discharge port, or the two frame members 5 may be spaced from each other in the longitudinal direction. Alternatively, the gap may be used as the discharge port.

Also in the present embodiment, as shown in FIG. 9, by attaching the cover material 3 illustrated in FIGS. 3 to 5 to the side wall surface 2c, rain can be generated by the groove-shaped member 3a as in the embodiment of FIG. It is possible to cover the stains and prevent deterioration of the appearance due to rain stains. Note that FIG. 9 shows a state in which the end portion of the side plate 5a is partially cut away, and in FIG. 9, 5d is a discharge port provided in the connecting plate 5b, and like the embodiment of FIG. Is attached to the side wall surface 2c so that one end of the groove member 3a faces the discharge port 5d and the other end is located near the lower end of the side wall surface 2c, so that the rain stain is covered by the groove member 3a. It is possible to prevent deterioration of the appearance of the wall-shaped body 2 due to rain stains.

In addition, in the case of wall-like bodies such as the corridors of apartments and apartments such as the corridors and handrails of balconies, etc. The body is divided into predetermined gaps, and the gaps are filled with a caulking material having elasticity and connected. That is, the two wall-shaped bodies have a connecting portion connected in the horizontal direction via a caulking material.

Since the surface of the caulking material 6 is recessed in the portion, a gap is present between the surface of the caulking material 6 and the frame material 4, as shown in FIG. 10B. Therefore, the gap can be used as the discharge port 4a, the rainwater that has fallen on the top surface 2a flows toward the frame member 4 due to the inclination of the top surface 2a, and the rainwater that has accumulated on the frame member 4 side can be 4 along the longitudinal direction of the frame member 4, and is discharged from the discharge port 4a at the connecting portion.

Since the rainwater discharged from the discharge port 4a travels down the surface of the caulking material 6 and falls downward, by covering the caulking material 6 with the cover material 7 as shown in FIG. Rain stains generated on the side wall surface 2c around the material 6 can be covered. In the case of the present embodiment, since the surface of the caulking material 6 is recessed inward from the surface of the side wall surface 2c to form a groove, the cover material 7 may be a long flat plate, one end of which is continuous with the frame material 4, It may be attached so that the other end is located near the lower end of the side wall surface 2c. Although the upper end of the cover member 7 is attached to the lower end of the frame member 4 in FIG. 10C, it may be attached so that the upper end of the cover member 7 overlaps the outer side of the frame member 4. ..
