Example (b): a prefabricated steel reinforcement framework for stairs, which is shown in figure 1, comprises an upper steel reinforcement mesh layer 1 and a lower steel reinforcement mesh layer 2 which are sequentially arranged in parallel from top to bottom. The upper reinforcing steel bar net layer 1 and the lower reinforcing steel bar net layer 2 are respectively formed by a plurality of threaded steels in a criss-cross mode, and the threaded steels are fastened through hooping steel wires.
Referring to fig. 1, reinforcing pipes 3 are laid between an upper mesh reinforcement layer 1 and a lower mesh reinforcement layer 2, four reinforcing pipes 3 are in a group, and each group of reinforcing pipes 3 is arranged in a W shape. Each set of reinforcement pipes 3 is distributed between the upper mesh layer 1 and the lower mesh layer 2 along the length direction of the upper mesh layer 1. In order to improve the connection strength between two adjacent reinforcing pipes 3, a connecting reinforcement 4 is welded between the two adjacent reinforcing pipes 3.
Referring to fig. 1, the reinforced pipe 3 is clamped between an upper mesh layer 1 and a lower mesh layer 2, and the reinforced pipe 3 is fixedly connected to the upper mesh layer 1 and the lower mesh layer 2 by welding. The reinforcing pipe 3 has the capability of bearing longitudinal load, and is matched with the upper reinforcing mesh layer 1 and the lower reinforcing mesh layer 2, so that the longitudinal bearing capability of the steel bar framework can be further improved.
