Fabricated beam string structure steel support construction technology
The invention discloses an assembly type beam string structure steel support construction technology, and belongs to the technical field of building construction. The construction method is realized through the seven steps of processing preparation, storage yard pre-assembly, embedded part construction, bracket beam construction, steel support installation, secondary grouting and prestress application. The beam string structure and the truss steel support can apply prestress through the prestress applying device to increase the nominal rigidity of the structure, deformation of the foundation pit is reduced, and the stability of the foundation pit is guaranteed. Earthwork below the supporting beam is excavated through a small excavator, the earthwork is coiled out of the supporting beam and then carried away through a large excavator, a specially-assigned person is commanded during mechanical operation, and the supporting beam is prevented from being collided. The on-site material storage area is close to the construction area, the horizontal transportation distance of the hoisted object is shortened, the hoisting transportation time of the hoisted object is shortened, and the risk is reduced. In the hoisting process, the large arm is kept towards the interior of the enclosure, and the probability of influencing the surrounding environment is reduced.
本发明公开了一种装配式张弦梁钢支撑施工工艺，属于建筑施工技术领域。本发明通过加工准备、堆场预拼装、预埋件施工、支架梁施工、钢支撑安装、二次灌浆和预应力施加这七个步骤予以实现。本发明中张弦梁及桁架钢支撑可通过预应力施加装置施加预应力增加结构的名义刚度，减少基坑变形，保证基坑的稳定性。本发明中支撑梁下面的土方采用小型挖机开挖，盘出到支撑梁外再用大挖机运走，机械作业时专人指挥，防止碰撞支撑梁。本发明中现场材料存放区靠近施工区域，减少吊物的水平运输距离，减少吊物吊装运输时间，降低风险。吊装过程中保持大臂朝向围挡内，减少对周边环境造成影响的几率。
