Old building reverse demolition method based on centralized control synchronous jacking system
The invention relates to an environment-friendly demolition method for an old building, relates to a reverse demolition method for the old building based on a centralized control synchronous jacking system, and belongs to the technical field of building demolition. According to the technology, a steel slide way and a horizontal support are used for horizontal limiting, a movable upper bracket is installed at the bottom of a beam and connected to a frame column through a high-strength steel bar, a fixed lower bracket is fixed to the bottom of the frame column, and the movable upper bracket and the fixed lower bracket transmit loads through an underpinning short column and a jack. A centralized control synchronous jacking system is adopted to operate a jack to jack an upper bracket, then underpinning of an original structure is completed, and cutting and dismantling can be started. The reverse demolition method for the old building is only implemented in the bottom protective layer, the protective layer has the dust removal and noise reduction effects, large equipment such as a tower crane is not needed, the danger of falling objects from high altitudes is avoided, and the method is high in automation degree and convenient to construct, shortens the construction period and saves the cost.
本发明涉及一种老旧建筑绿色环保拆除法，涉及一种基于集中控制同步顶升系统的老旧建筑逆向拆除法，属于建筑物拆除技术领域。该技术发明包括钢滑道和水平支撑进行水平限位，可移动上牛腿安装在梁底，通过高强度钢棒连接在框架柱，固定式下牛腿固定在框架柱底部，可移动上牛腿和固定式下牛腿通过托换短柱和千斤顶传递荷载，采用集中控制同步顶升系统操作千斤顶顶住上牛腿后完成对原结构的托换，可以开始切割拆除。本发明所述的老旧建筑逆向拆除法仅在底部防护层内实施，防护层具有除尘降噪的效果，且不需要塔吊等大型设备，不存高空坠物的危险，该方法自动化程度高、施工方便，节约工期，节约成本。
