PROBLEM TO BE SOLVED: To reinforce a strut without increasing a hole number or welding, and prevent coming-off of a beam material in a framework shelf equipped with a strut having an opening extending vertically. SOLUTION: Plural locking parts 15 are formed in the vertical direction on the fitting surface of a strut 10 having nearly a U shaped cross section having an opening extending vertically. Locking pawls 33 are formed at a pitch same as that of the locking parts 15, on the L-shaped gusset 32 in the end part of a main beam 30, and the beam 30 is installed in a hooked condition to the strut 10 by locking parts 15 and the pawls 33. A fixing pin 50 for fixing the strut 10 and the beam 30 in a hooked condition has two sets of regulating pins 52a and 52b on a pin rod 51, and is inserted in the penetrating condition of the pin 50 through the gasset 32 and the strut 10, then is turned about 90 deg. to be assembled; and in this inserted condition, two sets of the pins 52a and 52b nip a nipping side wall 13 to be made into a connected condition via the pin 50.
