Description

[Brief explanation of drawings]

Figures 1 to 7 each show an embodiment of the scaffolding structure for construction work of the present invention, and Figure 1 is a partially cutaway front view showing the joint structure between the support and the connecting member at the locked position of the rotating member. , FIG. 2 is a partially cutaway front view showing the coupling structure of FIG. 1 in the released position of the rotating member, and FIG.
The figure is a front view showing multiple types of struts with different lengths, FIG. 4 is a front view showing multiple types of tie materials with different lengths, and FIG. 5 is an exploded perspective view showing the joints of the tie materials. FIG. 6 is a side view showing the connection structure between the support and the bracket, and FIG. 7 is a perspective view showing the overall structure of the scaffold for construction work. FIGS. 8 and 9 are perspective views showing an example of the connection of columns and tie members in a conventional scaffolding structure for construction work. In the figure, 2... Support, 3...

Claims (1)

[Claims for Utility Model Registration] (1) A support that stands approximately vertically; a connecting protrusion that protrudes from the outer surface of the support and has a large-diameter head at its tip; and a position corresponding to the connecting protrusion. a connecting member disposed substantially horizontally; a terminal member fixed to the end of the connecting member and having a contact portion that abuts the outer surface of the support; and a terminal member fixed to the terminal member and hooked from above to the coupling protrusion. a locking member that restricts downward and horizontal movement of the tie member with respect to the support column; and a rotation member that is rotatably supported by the terminal member and has a locking portion that can be engaged with the coupling protrusion from below. and a rotatable member movably coupled to the terminal member, the rotatable member being pivotally arranged in a locked position in which the locking portion is located below the coupling protrusion and in a released position in which the locking portion is spaced apart from the coupling protrusion. Scaffolding structure for construction work, characterized by comprising: an operating member for controlling the operation; (2) The operating member is connected to the terminal member so as to be movable in a substantially vertical direction, and at its lower position positions and holds the rotating member at the locked position, and at its upper position moves the rotating member to the released position. The scaffolding structure for construction work according to claim 1, further comprising an engaging portion for disposing. (3) The scaffold structure for construction work according to claim 1, wherein the contact portion of the terminal member is formed in an arc shape with substantially the same curvature as the support column. (4) a support that stands approximately vertically; a connecting protrusion that protrudes from the outer surface of the support and has a large-diameter head at its tip; and a bracket that supports a scaffold board at a position corresponding to the connecting protrusion; an end member that is fixed to the end of the bracket and has an abutting portion that comes into contact with the outer surface of the column; and a terminal member that is fixed to the terminal member and hooked to the coupling protrusion from above so as to extend the bracket downwardly and horizontally relative to the column. a locking member that is rotatably supported by the terminal member and has a locking portion that can be engaged with the coupling protrusion from below; a pivoting member that is movably connected to the terminal member; an operating member for rotating the rotating member between a locking position in which the locking portion thereof is located below the coupling protrusion and a release position in which the locking portion is spaced apart from the coupling protrusion; and an operating member disposed below the terminal member. 1. A scaffolding structure for construction work, comprising: a holding member which is provided to the support member and which holds the bracket substantially horizontally by contacting the outer surface of the support column.
