Abstract

The utility model discloses a composite scaffold, which consists of rectangular module units connected with each other in X, Y and Z directions. Each rectangular module unit includes an upright bar, a cross bar, and a vertical diagonal stay and a horizontal diagonal stay, and the upright bars of the rectangular module units are connected with each other through a sleeve in the Z direction. The composite scaffold is characterized in that four butterfly-shaped clips are symmetrically arranged at the upper end and the lower end of each upright bar to connect the upright bar, the cross bar and the vertical and horizontal diagonal stays together to form the rectangular module unit; and the rectangular module units are connected with each other through the butterfly-shaped clips in the X and Y directions. The butterfly-shaped clips as the main connector can achieve effective connection of all bars on the nodes of the scaffold while ensuring intersection of the axes of the bars, so that the bars form a concurrent force system after bearing force. Accordingly, each bar has no additional stress to ensure the stable structure of the scaffold system.

The specific embodiment

The utility model is described in further detail below in conjunction with drawings and Examples.

As Fig. 1, Fig. 2, shown in Figure 3, a kind of combined scaffold is made of along space X, Y, the connection of Z direction the rectangular module unit, and the rectangular module unit is connected by sleeve 5 by vertical rod along space Z direction; Each rectangular module unit comprises vertical rod 1, cross bar 2, vertical and horizontal cable-stayed

support

3,4, each vertical rod upper and lower end all is arranged with four butterfly cards 7 becoming cross all around and vertical rod, cross bar, level and vertical cable-stayed support are linked together constitutes the rectangular module unit, and by this butterfly card the rectangular module unit is linked together along space X, Y direction.

As shown in Figure 3, Figure 4, butterfly card 7 is two parallel wing structures, and is affixed by block 8 between the both wings, and the chamber is inserted at the formation center; The upper and lower butterfly hook that is arranged with of the every wing of butterfly card, the hook angle of bend forms wedge shape space greater than 180 ° between hook hook end and the vertical rod.
