SHAPE STEEL SASH FRAME, SHAPE STEEL SASH UNIT AND SHAPE STEEL SASH COMPOSITE UNIT

摘要

PROBLEM TO BE SOLVED: To make a sash frame small size, high strength and a low cost by provide a main body part and a projection part orthogonal thereto, and combining the depth size of the main body part with shape steel larger than the size of the projection chart of the projection part to form an opening. ;SOLUTION: A shape steel sash unit 2 constitutes a shape steel sash frame by combining frame material 10 constituting an upper frame and a vertical frame and frame material 12 of a lower frame, and an opening division material is constituted by frame material 11 constituting an intermediate frame. The frame material 10 is provided with a main body part 10A disposed in the direction of depth and a projection part 10B projected in the direction of a projection chart, and formed of an L-shaped cross section. The frame material 11 is also provided with a main body part 11A and a projection part 11B, and formed of a T-shaped cross section. Design and visibility are improved by making the depth sizes of the main body parts 10A, 11A of the respective frame materials 10, 11 larger than the projection chart sizes of the projection parts 10B, 11B. Since hot extrusion formation shape steel is used for the frame materials 10, 11, the projection chart size can be suppressed to a minimum.;COPYRIGHT: (C)1998,JPO
