Load box for efficient self-balancing static load test and test method
The invention relates to a load box for an efficient self-balancing static load test and a test method, and belongs to the technical field of building construction. Comprising a top plate, a bottom plate and a hydraulic cylinder which are sequentially connected from top to bottom, and further comprises a distance measuring mechanism and a displacement detector, the distance measuring mechanism is vertically installed between the top plate and the bottom plate and used for detecting the distance variation between the top plate and the bottom plate, and the displacement detector is installed on a ground reference frame and used for detecting the distance variation between the bottom plate and the reference frame; the distance measuring mechanism is arranged in the load box to detect the displacement amount of the top plate and the displacement amount of the bottom plate in the load box, then the displacement amount of the top plate is obtained by subtracting the displacement amount of the bottom plate, the static load test is completed, and the problems that in the existing self-balancing static load test process, when a displacement observation system is built, efficiency is low, and meanwhile measurement errors are large are solved.
本发明涉及一种高效自平衡静载试验用荷载箱以及试验方法，属于建筑施工技术领域。包括自上而下依次连接顶板、底板和液压缸，还包括测距机构和位移检测器，测距机构垂直安装于顶板和底板之间并用于检测顶板与底板之间的距离变化量，位移检测器安装于地面基准架并用于检测底板与基准架的距离变化量；本发明通过在荷载箱内设置测距机构来检测荷载箱内顶板和底板的位移量，然后减去底板的位移量来获得顶板的位移量，以此来完成静载试验，解决了现有的自平衡静载试验过程中搭建位移观测系统时效率低的同时测量误差大的问题。
