Construction method of anti-deformation profile steel combined type platform for fire fighting corridor
The invention discloses a construction method of an anti-deformation profile steel combined platform for a fire-fighting corridor, which relates to the technical field of building engineering construction, and comprises the following steps: reserving a floor U-shaped pull ring hole in an elevator front room floor when the main body structure of the lower two floors of the fire-fighting corridor to be built is constructed, and erecting a cantilever girder by using the elevator front room floor; a cantilever main beam is fixed through a floor anchoring device, end beams are installed on the suspended side close to the cantilever main beam, longitudinal beams are connected to the end beams on the left side and the right side in a lap joint mode, and bearing beams are connected to the longitudinal beams on the upper side and the lower side in a lap joint mode. The lap joint positions of the longitudinal beams and the bearing beams are bound and connected through steel wire ropes and then tied to a shear wall so as to prevent sinking deformation, and a safe and reliable formwork supporting system platform is provided for a high-altitude overhanging outdoor fire fighting corridor without supporting points at the bottom. Therefore, cost is reduced, and concrete forming appearance quality is improved.
本发明公开了一种消防连廊用防变形型钢组合式平台施工方法，涉及建筑工程施工技术领域，包括：在需建设的消防连廊下两层，主体结构施工时，在电梯前室楼板预留楼板U型拉环洞口，利用电梯前室楼板搭设悬挑主梁，通过楼板锚固装置固定悬挑主梁，在靠近所述悬挑主梁悬空一侧，安装端梁，纵向梁搭接在左右两侧的所述端梁上，承接梁搭接在上下两侧的所述纵向梁上，所述纵向梁与所述承接梁搭接节点处用钢丝绳捆绑连接后拉结至剪力墙上以防止下沉变形，为底部无支撑点的高空悬挑的室外消防连廊提供一个安全可靠的模架支撑体系平台，通过本发明的方法将施工平台变形降至最低，从而降低成本，提高混凝土成型外观质量。
