Arched truss ground counter-force pre-pressing device
The invention discloses an arched truss ground counter-force pre-pressing device which comprises a body, and the body comprises a pre-pressing pedestal formed by connecting a transverse rod and a vertical rod in a perpendicular crossing mode and a counter-force beam fixedly connected to the bottom of the vertical rod. The pre-pressing pedestal is horizontally placed on the ground, an arched truss piece is laid on the pre-pressing pedestal, a limiting pier is fixedly arranged at the joint of the vertical rod and an arch ring of the truss piece of the pre-pressing pedestal, and the arch ring and the vertical rod are fixedly connected through the limiting pier; a counter-force pier base fixed on the vertical rod is supported at the bottom end of the counter-force beam, and a forcing device is arranged between the top end of the counter-force beam and a truss bottom beam of the truss piece. The invention aims to provide the ground counter-force pre-pressing device which can prevent the bracket from being in an upright state, and is short in construction period and high in arch truss pre-pressing efficiency.
本发明公开了一种拱形桁架地面反力预压装置，包括本体，所述本体包括由横杆和竖杆垂直交叉连接构成的预压台座，以及固定连接在竖杆底部的反力梁；所述预压台座平放在地面上，预压台座上铺设有拱形的桁架片，预压台座在竖杆与桁架片的拱圈交接处固定设置有限位墩，限位墩将拱圈与竖杆固定连接；所述反力梁的底端支撑有固定在竖杆上的反力墩座，反力梁的顶端与桁架片的桁架底梁之间设置有加力装置。本发明旨在提供一种避免支架处于直立状态，施工工期短，拱形桁架预压效率高的地面反力预压装置。
