Complex steel support structure close to existing subway and mounting and dismounting construction method
The invention relates to the technical field of constructional engineering, in particular to a complex steel support structure close to an existing metro and a mounting and dismounting construction method.The complex steel support structure close to the existing metro comprises a positioning steel plate arranged on the side face of an underground diaphragm wall, a bottom plate arranged at one end of the positioning steel plate, a full-length steel plate arranged on the side face of the bottom plate, a steel support arranged on the side face of the full-length steel plate and a supporting plate arranged at the bottom of the steel support; a bracket and a fixing plate are arranged on the side face of the underground diaphragm wall, a positioning ring is sleeved with the fixing plate, and a pull rod is arranged on the side face of the positioning ring. The dismounting method has the beneficial effects that the dismounting is carried out in a layered manner from bottom to top, when the steel support is dismounted, the bracket is adopted to support the steel support to be dismounted, then the jack is used for applying pre-pressure to dismount the movable end locking device, the end connecting part of the steel support is cut off by gas welding, the steel support is lifted out in sequence, and then the positioning steel plate, the bracket and the like are dismounted in sequence; stress on one side of the subway is prevented from sudden change.
本发明涉及建筑工程技术领域，具体为临近既有地铁复杂钢支撑构造及安拆施工方法，包括：地下连续墙侧面设置有定位钢板，定位钢板一端设置有底板，底板侧面设置有通长钢板，通长钢板侧面设置有钢支撑，钢支撑底部设置有托板，地下连续墙侧面设置有托架和固定板，固定板内套设有定位环，定位环侧面设置有拉杆；有益效果为：当进行拆卸时自下而上分层进行，拆除钢支撑时采用托架托住待拆除的钢支撑，然后在用千斤顶施加预压力卸去活动端锁定装置，用气焊切开钢支撑端头连接部位，依次吊出钢支撑，然后在依次将定位钢板、托架等进行拆卸，防止地铁一侧受力发生突变。
