Abstract
The utility model relates to a truss reinforcing bar stair which comprise a low-end beam, a high-end beam and a stair plate which lengthwise extends from the low-end beam to the high-end beam. The stair plate comprises multiple steps which are lengthwise arranged. The length direction, perpendicular to the lengthwise direction, of the steps is the horizontal direction. The truss reinforcing bar stair is characterized in that the stair plate comprises a lengthwise truss which is lengthwise arranged and a horizontal truss which is horizontally arranged. Thus, the truss reinforcing bar stair can form a bidirectional space stress structure which is more stable and more reasonable. On one hand, good strength and rigidity are achieved as dependency on concrete does not exist and on the other hand, a homogeneous elastic body different from traditional reinforced concrete can be formed by the truss reinforcing bar stair and concrete. Thus, the stair has superior rigidity and superior all-direction mechanical property which are proved by tests and becomes firmer. In addition, the thickness and the dead weight of the stair plate can be greatly reduced by means of the structure, and therefore space and concrete materials are saved and design and construction of a stair support supporting structure can be easier and more convenient.
