In an interior decorating plate 14, upward linear projections 9, 10 are formed along the width direction, long nuts 16 connectable to stringers 11 are fitted to both ends of the linear projections 9, 10, and both of the front/rear directional end parts of the decorating plate 14 are erected diagonally to form erected elements 11, 12. The decorating plate 14 is placed on and fixed to an upper surface 6a of the bottom plate 6, and front ends 11a, 12a of the erected elements 11, 12 are brought into contact with the joint elements 2, 4 to form a landing unit 20. Pathway units 20, 20 are arranged to be adjacent in the front/rear direction. The joint elements 2, 4 provided in the front and rear are overlapped with each other and are fixed to side plates 22, 22, and mortar is filled to form a landing. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
