Emergency rescue and reinforcement treatment method for sudden damage of existing building center pillar
The invention relates to the technical field of building center pillar reinforcement, in particular to an emergency rescue reinforcement treatment method for sudden damage of an existing building center pillar. Comprising the following steps that a plurality of steel plate sleeves are additionally arranged on the periphery of a damaged center pillar, and the multiple steel plate sleeves are sequentially stacked between the bottom of an upper floor and the ground of a lower floor; the hollow reinforced concrete underpinning column with the steel bars on the inner side, the steel plate sleeve on the outer side and filled high-strength concrete as a whole is formed by pouring in the steel plate sleeve. Before construction, a plurality of hydraulic supporting devices are pre-installed between the upper floor bottom and the lower floor ground of the damaged middle column; vertical steel stirrups are additionally arranged on the periphery of the damaged middle column in advance before pouring, and the steel stirrups are supported between the bottom of an upper floor slab and the ground of a lower floor; the hollow reinforced concrete column has the beneficial effects that the hollow reinforced concrete column is adopted for underpinning load treatment, and through pouring, the problem that comprehensive closed supporting and reinforcing cannot be conducted is solved.
本发明涉及建筑中柱加固技术领域，更具体的说是既有建筑中柱突然损坏的抢险加固处理方法；包括以下步骤：在破坏的中柱周边增设多个钢板套，多个钢板套依次堆叠设置在上楼板底和下楼地面之间；通过在钢板套内浇筑，形成以内侧为钢筋、外侧为钢板套、填充高强砼三者为一体的空心劲型钢筋砼托换柱；在施工前先预安装多个液压支撑装置在破坏的中柱的上楼板底和下楼地面之间；在浇筑前预先在破坏的中柱周边增加竖向的钢箍筋，钢箍筋支撑在上楼板底和下楼地面之间；本发明的有益效果为通过采用空心劲型钢筋砼柱进行托换荷载处理通过浇筑，进而解决无法进行全面封闭的支撑加固的问题。
