<p>PROBLEM TO BE SOLVED: To work a hole simply by inclining and supporting a handrail member by the end section of a support while forming the closing cross section of the handrail member by mutually engaging half members and forming the hole by mutually connecting recessed notched sections at the opposed end sections of the half members. SOLUTION: A plurality of upper materials 5 and lower materials 6 are juxtaposed in series in the longitudinal direction of a handrail member 4, and the handrail member 4 in specified length is formed by engaging the engaging sections of the upper material 5 and the lower material 6. The mutually adjacent places B of the lower materials 6 are conformed to the places of supports 3, and the upper ends of the supports 3 are penetrated into holes 7 formed at the adjacent places B and reach the inside of the handrail member 4. Recessed notched sections 7A and 7B formed at the mutually opposed end sections of the mutually adjacent lower materials 6 are connected in the holes 7. Since the upper ends 3A of the supports 3 are tilted in the horizontal direction, the handrail member 4 has an angle of inclinationαto the supports 3, and connecting members 9 are crossed onto pairs of projections 8 of the lower materials 6. Accordingly, the holes can be worked simply.</p> |
