This paper aims to show the applicability of the scissors system to the temporary structure. Since the traditional scissors has the simple "deployable mechanism", it has the merit that it is possible to save the time of the assembly work. On the other hand, in the traditional scissors there are structural problems which are not only that the stiffness of structures after completion is not sufficient to resist load but that the bending moment generated at the main members is relatively large. To solve these problems, in this paper, authors propose String Scissors Structure (SSS). SSS is reinforced with the strings, and it is applied to the truss which the bending moment doesn't occur to. Authors demonstrate the structure property of SSS, and propose new concept of method of reinforcement and manpower construction.
