Existing building elevator foundation deepening four-wall supporting construction method
The invention relates to an existing building elevator foundation deepening four-wall supporting construction method and belongs to the technical field of elevator reinforcement. The existing buildingelevator foundation deepening four-wall supporting construction method comprises the following steps: statically cutting an opening on an original elevator four-wall position according to a snapped external edge line; drilling holes on the original structural foundation of the periphery of the original elevator four-wall position at mounting column underfoot steel plates; mounting steel columns and steel beams; and carrying out settling observation. Through the formation of the opening on the original elevator four-wall position and through the supporting of the steel beams, the load of the upper part of the elevator four-wall position directly acts on a steel structure supporting system, the layer-by-layer erection of full scaffolding is not needed, and the influence on the constructionor normal use of an upper-part building is prevented; the existing building elevator foundation deepening four-wall supporting construction method is convenient and rapid, lower in material consumption and lower in cost; the flat area occupied by the supporting system is reduced; and the construction progress is accelerated.
本发明涉及既有建筑电梯基础加深四壁支撑施工方法，属于电梯加固技术领域。包括在原电梯四壁依据所弹外边线进行洞口静力切割、在安装柱脚下钢板处的原电梯四壁外围原结构基础上打眼成孔、钢柱钢梁安装以及沉降观测等步骤。本发明通过在原电梯四壁开洞，支设钢梁，电梯四壁上部的荷载直接作用在钢结构支撑体系上，不需要逐层搭设满堂脚手架，不影响上部建筑的施工或正常使用，具有方便快捷、节省材料，降低成本，减少了支撑体系占用的平面面积，加快了施工进度。
