Prestressed steel strand-concrete combined step plate structure and construction method
The prestressed steel strand-concrete combined step plate structure comprises a flat-plate-shaped prefabricated concrete step, embedded steel bars are arranged at the two ends of the bottom face of the prefabricated concrete step respectively, the top ends of the embedded steel bars are embedded into the prefabricated concrete step, and the bottom ends of the embedded steel bars are exposed; tensile rib plates are arranged at the upper ends and the lower ends of the embedded steel bars respectively, and the exposed ends of the embedded steel bars located at the two ends are connected through prestressed steel strands. The stair beam bearing steel parts are fixed on the stair beams and located at the two ends of the bottoms of the prefabricated concrete steps, and each stair beam bearing steel part comprises an L-shaped body, a grouting baffle and a stiffening rib, wherein the grouting baffle and the stiffening rib define a rectangular box body with an opening in the top; a reserved wire groove is formed in the top of the grouting baffle, the prestressed steel strand is embedded into the reserved wire groove, the bottom end of the embedded steel bar is located in a rectangular box defined by the grouting baffle, and concrete grouting materials are poured into the rectangular box. The device is light in weight, low in mounting precision requirement and high in mounting speed.
本发明涉及一种预应力钢绞线‑混凝土组合踏步板结构及施工方法，包括平板形状的预制混凝土踏步，预制混凝土踏步的底面两端分别设有预埋钢棒，预埋钢棒的顶端嵌入预制混凝土踏步内部，预埋钢棒的底端外露，预埋钢棒的上下两端分别设有抗拉肋板，位于两端的预埋钢棒的外露端之间通过预应力钢绞线连接。还包括固定在梯梁上且位于预制混凝土踏步底部两端的梯梁承托钢件，梯梁承托钢件包括L型本体、围合成顶部敞口矩形箱体的灌浆挡板、加劲肋；灌浆挡板顶部形成预留线槽，预应力钢绞线嵌入预留线槽内，预埋钢棒的底端位于灌浆挡板围合的矩形箱体内，矩形箱体内灌入混凝土灌浆料。本发明重量轻、安装精度要求低、安装速度快。
