PURPOSE:To eliminate the need for welding for the assembling of frame elements and using a simple means such as bolting for the assembling, by assembling corner metallic fixtures opened in an angle freely and providing link pieces. CONSTITUTION:The corner metallic fixture 11 consists of a combination of a couple of members 12, 12' for the corner metallic fixture, and the members 12, 12' comprise cylindrical coupling sections 13, 13' and the link pieces 14, 14' provided incorporatedly with the sections 13, 13' as shown in figure. Further, an inner circumference surface 18 of a projection 16 is formed tapered. The longiitudinal link piece 14 is formed incorporatedly with the outer circumference of the cylindrical coupling section 13 and the upper end surface of the link piece 14 is arranged for the height so as to be mated with the upper end surface of the other corner metallic fixture member 12'. Moreover, a step 19 to insert the outer side surface of the frame elements 10 without a step difference is provided for the outer side surface of the link piece 14. |
