Energy-saving and heat-insulating prefabricated stair

The utility model provides an energy-saving heat-preservation prefabricated stair which comprises a stair body, through holes are formed in the inner side of the stair body, reinforcing steel bars are arranged in the stair body, and a heat-preservation mortar layer is arranged at the bottom of the stair body. According to the energy-saving and heat-insulating prefabricated staircase, the weight of the staircase body can be effectively reduced through the arrangement of the through holes, hoisting is facilitated, the material consumption is reduced, more materials are saved, the structural strength of the staircase body can be improved through the use of the reinforcing steel bars, the overall structure is simple and practical, and cost is low. The problem that hoisting is inconvenient due to the fact that the weight of the ladder body is large is effectively solved, more energy and materials are saved, and the structural strength is high. 本实用新型提供一种节能保温的预制楼梯包括梯体，所述梯体的内侧开设有通孔，所述梯体的内部设置有钢筋，所述梯体的底部设置有保温砂浆层。本实用新型提
