The width of the sealing material is substantially the same. A slit 46 is formed on the lower surface of the inner hollow portion 22, that is, the concave contact surface 16 b, with a width S in which an outer bead described later can be fitted.
[0024]
With reference to FIG.
[0025]
A concave portion 8 is formed in the core material 5, a surface decorative steel plate 6 is pasted on the surface of the core material 5, a back decorative steel plate 7 is pasted on the back surface, and a concave decorative steel plate 9 is pasted on the concave portion 8. .
[0026]
A required number of simple embedded nuts 32 are inserted from the front side of the surface-coated steel sheet 6 along the periphery of the recess 8. The simple embedding nut 32 has a spring piece 33 that contracts toward the center, and the tip of the spring piece 33 bites into the groove of the screw so that the screw is held.
[0027]
A pilot hole corresponding to the position of the simple embedding nut 32 is formed in the fixed surface 16 a of the decorative frame 14. The drilling position of the lower hole coincides with the scoring groove 28, and in order to correspond to the simple embedding nut 32, it is only necessary to take a dimension along the scoring groove 28. Further, the V-groove shape of the scribe groove 28 has a function of positioning the drill tip.

The sealing material 35 and the sealing material 36 are highly elastic and highly deformable materials. For example, a double-sided tape is preliminarily pasted on both the upper and lower surfaces of the sealing material 35 and the sealing material 36. The thickness and the amount of deformation are sufficiently larger than the processing error that occurs when the concave portion 8 is formed.
[0031]
In addition, the sealing material should just be a highly elastic and highly deformable material. For example, it is preferably made of a soft synthetic resin such as vinyl chloride or urethane, or rubber, and these sponge-like porous materials are preferred.
[0032]
Further, the sealing material may be structured to be sealed with the same quality material, but may be structured to seal a plurality of different materials in series, parallel or overlapped, and further, a plurality of different materials. It is good also as a structure sealed with the composite material processed and formed beforehand.

The attachment of the decorative frame 14 is completed simply by pushing the tapping screw 34 into the simple embedding nut 32, which is a one-touch operation. By pressing the outer hollow portion 20 evenly against the surface decorative steel plate 6, the sealing material 35 is in close contact with the surface decorative steel plate 6 in a sufficiently compressed state, and the sealing material 36 is against the concave decorative steel plate 9. Adhering in a sufficiently compressed state, the surface-coated steel sheet 6 and the outer hollow portion 20 and the recess 8 and the inner hollow portion 22 are liquid-tightly sealed. Accordingly, rainwater or the like is prevented from entering between the door body 1 and the decorative frame 14. Further, the deformation error of the concave portion 8 is absorbed by the deformation of the sealing material 35 and the sealing material 36, so that the surface decorative steel plate 6 and the outer hollow portion 20 are interposed between the concave portion 8 and the inner hollow portion 22. A gap can be prevented from being generated.
[0035]
Next, FIG. 2 shows a case where a decorative frame 37 composed of the same decorative molding 16 as the decorative frame 14 described above is used as a decorative frame for a window.
[0036]
