PROBLEM TO BE SOLVED: To make it possible to mount surrounding plates used for roof or exterior wall to beam without using any bolt and screw. SOLUTION: Rise sections 4a an 4b are formed on both sides of each of metal surrounding plates 4, and an outside fitting section and an inside fitting section are respectively to the upper parts of the rise sections 4a and 4b. A plurality of surrounding plates 4 are prepared, their rise sections 4a and 4b are connected to each other and, at the same time, a plurality of outside and inside fitting sections are fitted to each other to arrange them in parallel. A slide interlocking section 6b of a metal fixture 6 is fitted to a fitting section between the surrounding plates 4 and 4 in a slidable manner, and a holding section 6a of the metal fixture 6 is fitted to a horizontal section 2a of a beam 2. By the constitution, the surrounding plates 4 can be mounted to the beam without using any bolt and screw. |
