Kind Code:
B2
Abstract:
To provide a connection joint for vertically connecting a metal pipe column in a temporary scaffold.SOLUTION: In regard to a locking mechanism (8) for preventing an upper support (1b) from coming off and engaging the upper support in an inserted state in which the upper support is externally inserted into an upper insertion tube (5) in a connection joint, the locking mechanism is composed of: a lock piece (21) which moves between a lock position (P1) and an unlock position (P2) with respect to a guide hole (5a) from an inside of the upper insertion body; a spring member (22) configured to bias the lock piece toward the lock position; and an operation mechanism (23) for moving the lock piece to the unlock position via the spring member. When a moving body (29) is moved from a standby position (Q1) to an operating position (Q2), the operating mechanism (23) is configured such that a driving unit (30) of the moving body presses and elastically deforms the spring member (22) to move the lock piece (21) to the unlock position (P2); in this state, engagement means (31) is provided for engaging and holding the moving body (29) at the operating position (Q2) by turning the moving body from a release position (R1) to an engagement position (R2) around the shaft of the moving body.SELECTED DRAWING: Figure 8
