Foam concrete filled pyramid-shaped three-dimensional lattice sandwich structure pier anti-collision device
The invention discloses a foam concrete filled pyramid-shaped three-dimensional lattice sandwich structure pier anti-collision device which comprises inner and outer side steel plate anti-collision layers, a foam concrete filled pyramid-shaped lattice structure buffer energy absorption layer, angle steel connecting pieces, high-strength bolts and joint filling materials. Corresponding anti-collision sandwich structures and connecting pieces can be selected according to different pier section shapes and working conditions, and the anti-collision structures are connected through angle steel connecting pieces and high-strength bolts. Compared with a traditional rigid anti-collision device, the device can absorb collision energy through plastic deformation and brittle deformation of a composite material, the collision force peak value is reduced, and the safety of a pier and a vehicle can be protected at the same time. The device is convenient to manufacture and replace, small in occupiedarea and small in adverse effect on urban traffic.
本发明公开了一种泡沫混凝土填充金字塔型三维点阵夹芯结构桥墩防撞装置，包括内外侧钢板防撞层，泡沫混凝土填充金字塔型点阵结构缓冲吸能层，角钢连接件，高强螺栓和填缝材料。本装置可根据不同的桥墩截面形状和工况选择相应的防撞夹芯结构和连接件，防撞结构之间通过角钢连接件和高强螺栓连接。与传统刚性防撞装置相比，本装置可通过复合材料的塑性变形和脆性变形吸收撞击能量，降低撞击力峰值，能同时保护桥墩和车辆的安全。本装置制作、更换方便且占地面积较小，对城市交通造成的不利影响较小。
