CONSTITUTION:A L-shaped supporting metal fitment 2 with a hole 3 is attached to each corner of a base 1 with holes 4. A lower end of each post 5 formed with troughs 6, 7 is provided with a hole 3 and a threaded connecting pin 9, and an upper end of each post 5 is formed into L-shape and provided with a hole 11. Each beam 12 is provided with connecting pins 13 and a U-shaped horizontal trough outwardly extending from a lower side of the beam and formed with a slit 14A at a center of the trough. An upper end of each center post 15 which also acts as a trough is provided with a hole 16, and a lower end 17 of the center post is provided with a hole to be communicated with the hole 4 and to be fitted with a connecting pin. The posts 5 and center posts 15 are placed in position initially by inserting the connecting pins 9 into the holes 3, 4 and then remaining holes not inserted with the connecting pins are inserted with bolts. Then the threaded connecting pins 13 of the beams 12 are caused to be inserted into the holes 11, 16 of the posts 5 and center posts, and a roof 20 and doors 21 are attached to complete the assembling. |
