High-strength prefabricated stair, mounting structure and construction method of high-strength prefabricated stair
The invention provides a high-strength prefabricated stair, a mounting structure and a construction method of the high-strength prefabricated stair. The prefabricated ladder comprises a ladder beam top building surface layer, a connecting bolt is arranged on the ladder beam top building surface layer and can be inserted into a matching hole of a prefabricated ladder body, a guiding circular truncated cone is arranged on the ladder beam top building surface layer, and the lower bottom face of the guiding circular truncated cone is connected to the ladder beam top building surface layer; and the connecting bolt vertically penetrates through the middle part of the guide circular table and extends to a position above the guide circular table. And the connecting bolt and the matching hole are concentric, so that the centering property between the connecting bolt and the matching hole is improved to the greatest extent, and the overall connecting strength is greatly improved.
本发明提供了一种高强度预制楼梯、安装结构及其施工方法。本发明包括梯梁顶建筑面层，梯梁顶建筑面层上设有连接螺栓，连接螺栓可插入到预制梯体的配合孔内，梯梁顶建筑面层上设有导向圆台，导向圆台的下底面连接于梯梁顶建筑面层，连接螺栓垂直贯穿于导向圆台的中部且延伸至导向圆台上方位置。连接螺栓与配合孔相互同心，从而最大程度提高连接螺栓与配合孔之间的对中性，整体连接强度得到了大幅度的提升。
