Connecting device between main beam and jack in plate load test
The invention discloses a connecting device between a main beam and a jack in a plate load test, and relates to the technical field of on-site in-situ plate load tests, in particular to the connecting device between the main beam and the jack in the plate load test. The connecting device comprises a pressure bearing plate, the jack installed on the pressure bearing plate, a pressure sensor installed on the jack, a force transmission support installed on the pressure sensor and a bottom threaded connector installed between the force transmission support and the pressure sensor, and a clamping groove is formed in the force transmission support. According to the connecting device between the main beam and the jack in the plate load test, through arrangement of a handle, position adjustment and installation of the connecting device can be facilitated, and convenience is improved; by adopting an inverted special-shaped circular truncated cone made of high-strength steel, the contact area between the jack and a main beam support can be increased, and the problem that due to the small contact area, the main beam is locally sunken and deformed excessively is effectively solved; an arranged rubber thin pad can be used for increasing the horizontal friction force between the upper surface of the force transmission support and the main beam in the loading process, and the slipping is prevented.
本发明公开了一种平板载荷试验中主梁与千斤顶间的连接装置，涉及现场原位平板载荷试验技术领域，具体为一种平板载荷试验中主梁与千斤顶间的连接装置，包括承压板、安装在承压板上的千斤顶、安装在千斤顶上的压力传感器、安装在压力传感器上的传力支座，以及安装在传力支座与压力传感器之间的底部螺纹接头，所述传力支座上开设有卡槽。本发明通过把手的设置，可便于连接装置位置的调整和安装，增加便捷性；通过采用高强度钢制作的倒立式异形圆台，能够增大千斤顶与主梁支架安间的接触面积，有效减小因接触面积小导致的主梁局部凹陷变形过大的问题；通过设置的橡胶薄垫可用于加载过程中增加传力支座上表面与主梁之间的水平向摩擦力，防止打滑。
