Elevated rail bridge

一种高架轨道桥

Abstract

The utility model relates to an elevated rail bridge which comprises pillars, a reinforced concrete foundation and a steel rail, the pillars are mounted on the concrete foundation through a foundation embedded part; meanwhile, pillar base plates are connected on the upper end surfaces and the lower end surfaces of the pillars, the pillar upper base plate is connected with a steel rail iron base, the left end and the right end of the steel rail iron base in the vertical direction are respectively provided with a mounting boss, elastic bar III type fasteners are mounted on the bosses, two sides of the steel rail are tightly clamped through elastic bars of the elastic bar III type fasteners, thereby fixing the steel rail on the pillars and connecting the pillar lower base plate with the foundation embedded part. As the new connecting way is adopted between the pillars and the ground, the construction is convenient; when the foundation of the rail bridge is settled after use, a cushion can be added for repair, thereby having good applicability; meanwhile, the insulation and shock absorption between the steel rail and the pillars can be realized under the action of the elastic bar III type fasteners, thereby ensuring the safety of maintenance operation, reducing walking vibration of a rail motor car and effectively preventing the steel rail from creeping.
本实用新型涉及一种高架轨道桥,包括支柱、钢筋混凝土基础以及钢轨,支柱通过基础预埋件安装在混凝土基础上,同时,支柱上下端面连接支柱座板,支柱上座板连接钢轨铁座,所述钢轨铁座竖直方向的左右两端各有一安装凸台,弹条III型扣件安装在凸台上,通过弹条III型扣件的弹条将钢轨两侧卡紧,从而将钢轨固定在支柱上,支柱下支柱座板与基础预埋件连接。由于支柱和地面之间采用了新的连接方式,施工方便,当轨道桥基础使用后沉降时,可以加垫修复,具有良好的适用性,同时,钢轨与支柱之间在弹条III型扣件的作用下能绝缘和减震,从而确保维修作业安全,减少动车行走震动,并能有效防止钢轨爬行。
