High-speed rail station building main body steel structure construction method
The invention discloses a construction method of a high-speed rail station building main body steel structure. The method comprises the following steps: prefabricating each component, and transporting to a construction site after prefabricating; then, strain sensors are arranged at the corresponding positions of the latticed columns and used for monitoring deformation in the construction process; the support is lifted on site, after the lifting mechanism is erected, the lifting part is lifted, then the foundation section and the branch section are hoisted, the rod pieces are embedded, and installation of the whole steel structure is completed; and finally, step-by-step unloading is conducted, and deformation monitoring is conducted on the latticed column in the unloading process through a strain sensor. And after unloading is completed, the lifting support is detached. All the components are prefabricated in a factory so as to shorten the construction period, and standardization and construction period shortening are facilitated. Compared with high-altitude scattered splicing, high-altitude operation can be reduced to a great extent, the operation intensity can be reduced, the number of splicing nodes is relatively small, stress and strain monitoring can be conveniently carried out during unloading, and the construction safety can be improved. And on the other hand, the using amount of hoisting machinery can be reduced, energy consumption is reduced, noise is reduced, and the environment friendliness of construction is improved.
本发明公开了一种高铁站房主体钢结构施工方法。本方法先预制各部件，预制完成后运输至施工现场。然后在格构柱对应位置布设应变传感器用于在施工过程中监测变形；现场提升支架、提升机构搭设完成后，提升提升部，再吊装基础段、分支段并嵌补杆件，完成整个钢结构的安装；最后逐级卸载，通过应变传感器对卸载过程中格构柱进行变形监测；卸载完成后拆除提升支架。各部件在工厂预制以便缩短工期，利于实现标准化和缩短工期。相较高空散拼，能够极大程度上的减少高空作业，降低作业强度，并且拼装节点相对较少便于在卸载时进行应力应变监测，利于提高施工安全性。另一方面，能够减少吊装机械用量，降低能耗，减少噪音的产生，利于提供施工的环保性。
