<p>PURPOSE: To improve the execution property by surrounding the periphery of a rectangular panel with a folding frame body made of an aluminum molded frame material, and pivotally connecting the frame body with two connecting members. CONSTITUTION: This built-up panel 1 is formed with a rectangular panel 2 made of a plastic corrugated sheet and an aluminum molded frame body 3 constituted of a pair of mating vertical frames 3a and a pair of horizontal frames 3b. The vertical frames 3a are pivotally connected by two connecting members 32 while the coupling grooves are arranged face to face, frames 33 are provided at both end sections of the connecting members 32, and they are pivotally fitted to pivotal shafts 34. When the connecting members 32 are moved near to each other in parallel, both vertical frames 3a are located outside the connecting members 32, and this built-up panel 1 can be folded. The panel 1 is simplified in design, it is made lightweight, and its durability can be improved.</p> |
