PURPOSE: To make it possible to connect a scaffolding board easily and definitely by opening both ends and inserting the scaffolding board into an aluminum-made square cylinder-shaped scaffolding connector to which a bulkhead is installed in the central part from both ends and pushing the scaffolding connector upward with a fixing screw rod threaded with a screw hole installed to the bottom.

CONSTITUTION: Both ends of a square cylinder-shaped body 1 are opened. In the substantially central part of the body, there is installed a bulkhead 13 in the radial direction, which is divided into two scaffolding sections 9 and 11. When wooden scaffolding boards 3 and 4 are inserted, some upper and lower clearances are arranged to exist and the square cylinder- shaped body is manufactured of aluminum. Square cylinder-shaped reinforcing members 21, 23 and 25 are outwardly fitted in both ends and the central part of the square cylinder- shaped body 1 where the wooden scaffolding boards 3 and 4 are inserted in the scaffolding insertion parts 9 and 11 from both opening ends. A presser screw rod 15 is threaded with the scaffolding board insertion parts 9 and 11 and a screw hole installed on the bottom of the reinforcing members 21, 23 and 25, thereby pressing the scaffolding boards 3 and 4 upward so that they may be fixed. A plurality of non-slip holes 27 are installed on the top of the scaffolding insertion parts 9 and 11, thereby reducing the weight of the square cylinder-shaped body 1.
