Rotating beam type stair single-limb beam step component and rotating beam type stair construction method
The invention discloses a rotating beam type stair single-limb beam step component and a rotating beam type stair construction method, and belongs to the technical field of rotating beam type stair construction. The rotating beam type stair single-limb beam step component comprises a component body, the component body is of a 7-shaped structure, the transverse outer side of the upper portion and the transverse inner side of the lower portion of the component body are provided with preset steel bars extending out of the outer side of the component body, the longitudinal inner side of the component body is provided with anchoring steel bars extending out of the outer side of the component body, and a weight reduction structure is arranged in the component body. Through the arrangement of the stepping component, based on the characteristics of large bearing capacity and light self weight, the stair can be used for design and construction of spiral stairs with different treads and special-shaped stairs overhung on one side; single components are identical in specification and size, and a unified single mold is adopted, so that the construction cost can be reduced; prearranged steel bars are arranged on the step components and matched with a jacking and supporting tool, and jacking and supporting formwork of the stair can be achieved. Based on the structural design of the jacking tool, the formwork erecting angle can be adjusted, and the requirements of different construction working conditions are met.
旋转梁式楼梯单肢梁踏步构件及旋转梁式楼梯施工方法，属于旋转梁式楼梯施工技术领域。旋转梁式楼梯单肢梁踏步构件，包括构件本体，构件本体呈7字型结构，其上部横向的外侧及下部横向的内侧设有延伸出构件本体外侧的预置钢筋，其纵向的内侧设有延伸出构件本体外侧的锚固钢筋，构件本体的内部设有减重结构。本发明通过设置的踏步构件，基于承载大，自重轻的特点，能够用于不同踏面的旋转楼梯和单侧悬挑的异形楼梯的设计施工；单一构件，规格尺寸相同，采用统一的单一模具，能够降低施工成本；踏步构件上设置有预置钢筋，配合顶撑工具，能够实现楼梯的顶撑支模；基于顶撑工具的结构设计，能够调整支模角度，满足不同施工工况的需求。
