Bucking of preventing in bridge antidetonation retrains supporting member

The utility model discloses a bucking of preventing in bridge antidetonation retrains supporting member, enclose the frame before including and enclose the frame after with, before enclose the frame with after enclose and all be equipped with the restraint in the frame and support, before enclose the frame with after the space of enclosing between the frame to enclose formed the cross cavity, be equipped with the kernel in the cross cavity and support, wherein, for restraint surrender section in the middle of the kernel supports, the kernel supports both ends and is unconstrained non - surrender section, for retraining non - surrender section between unconstrained non - surrender section that the kernel supported and the restraint surrender section. The beneficial effect of the utility model: simple structure, quality are light, the construction is simple and convenient, it is convenient to safeguard, the security performance is good, have still improved bridge anti under earthquake and other accidental action simultaneously and have collapsed, have resisted ability of coming off and power consumption ability.
