Detailed Description
The invention will be further described with reference to specific embodiments. It is to be understood that the following description is only for purposes of clearly illustrating the present invention and is not to be taken in a limiting sense.
Referring to fig. 1 to 6, the scaffold gangboard is composed of a gangboard frame 1, cross bars 2, longitudinal bars 3 and the like. The springboard frame 1 is of a rectangular structure, and two ends of the cross rod 2 are respectively and vertically welded to the inner sides of two short edges of the springboard frame 1. Two L-shaped buckles 4 are welded above one of the short edges of the springboard frame 1, as shown in fig. 2, and are used for connecting adjacent springboards. The long limit of one side of springboard frame 1 is equipped with the trompil of a plurality of equipartitions, and the diameter of trompil matches with the diameter of vertical pole 3, supplies vertical pole 3 to pass in the trompil. After the vertical rod 3 passes through the opening, one end of the vertical rod is vertically welded on the long edge of the springboard frame 1 which is not provided with the opening, and the other end of the vertical rod exceeds the long edge provided with the opening. Three longitudinal rods 3 with threads 7 are arranged at the positions beyond the ends, one longitudinal rod is positioned in the middle of the springboard frame 1, and the other two longitudinal rods 3 are respectively arranged at the two ends of the springboard frame 2. Taking the vertical rod positioned at the middle position as an example, one end of the vertical rod 3 provided with threads is provided with a movable clamping piece 6 with an arc, and as shown in fig. 3 and 4, the movable clamping piece 6 with the arc is fastened through a nut 8 and a gasket 9; and a fixing clamping piece 5 with an arc is arranged on the outer side of the long edge where the other end of the longitudinal rod 3 is positioned, as shown in figure 2.
