摘要
对某高层住宅大悬挑阳台高支模架的构造及施工作了介绍,通过对模架在混凝土浇筑过程中的荷载、变形和振动响应的实时监测,发现了支模架立杆上的恒荷载与设计计算值较接近,而施工荷载差别较大,施工过程中的人员与振捣荷载一般不超过1k N/m^2;同时发现混凝土输送泵的作业对支模架的整体稳定有一定影响,需要加以重视。
The structure and construction of a large cantilevered balcony with high formwork support were introduced in this paper. By the site measurement for the loads, deformation and shaking respond, it is founded that permanent load of upright tube is similar between the designed value with the measuring one and the construction load is more difference, and the vibrating load of vibrator and personnel load are not greater than 1kN/m^2, and the influence of the concrete pump is fairly obvious for the stability of the formwork support as a whole and more attention could be paid to.
