Curved bridge transverse limiting device based on steel stop blocks
The invention belongs to the technical field of bridge deviation prevention, and particularly relates to a curved bridge transverse limiting device based on steel stop blocks. The device comprises an upper bottom plate and a lower bottom plate which are arranged in parallel; a plurality of steel baffles which are arranged at equal intervals are vertically arranged at the bottom of the upper bottom plate, a trapezoidal plate is arranged between every two adjacent steel baffles, the bottom end of each trapezoidal plate is vertically fixed to the upper surface of the lower bottom plate, the two sides of the top end of each trapezoidal plate are detachably connected with hemispherical force transmission keys, and the hemispherical force transmission keys make contact with the steel baffles; when a load acts on a bridge, the upper baffle and the lower bottom plate generate relative transverse displacement, transverse displacement occurs between the steel baffle and the trapezoidal plate by taking the hemispherical force transmission key as a force transmission point, so that the bottom of the trapezoidal plate generates buckling deformation, and the buckling deformation of the trapezoidal plate consumes energy generated by the load to limit the displacement of a beam and a bridge pier. The anti-deviation device is better in anti-deviation effect; and repeated utilization or local replacement can be realized, so that the cost is greatly reduced.
本发明属于桥梁防偏技术领域，具体涉及一种基于钢挡块的曲线桥梁横向限位装置。本发明包括平行设置的上底板和下底板；所述上底板的底部垂直设有若干等间距间隔设置的钢挡板，两相邻钢挡板之间设有梯形板，梯形板的底端垂直固定在下底板的上表面，梯形板顶端的两侧可拆卸连接有半球形传力键，半球形传力键与钢挡板接触；当荷载作用在桥梁上，上挡板与下底板产生相对横向位移，以半球形传力键为传力点，钢挡板与梯形板之间发生横向错动，使梯形板底部产生屈曲变形，梯形板的屈曲变形消耗荷载产生的能量，以限制梁与桥墩的位移。本发明防偏移效果更好；可重复利用，或者局部更换，大大降低成本。
