Fabricated steel rail structure for urban rail construction and construction method thereof
The invention discloses a fabricated steel rail structure for urban rail construction and a construction method thereof.The fabricated steel rail structure comprises a steel rail body, an outer protective layer is arranged outside the steel rail body, a damping layer is arranged in the outer protective layer, reinforcing ribs are integrally connected to the inner wall of the outer protective layer, and the reinforcing ribs are inserted into the damping layer; a mass block is arranged in the damping layer, a reinforcing layer is arranged in the outer protection layer, a conducting layer is arranged on the outer wall of one side of the reinforcing layer, and a sound absorption layer is arranged on the outer wall of the other side, away from the reinforcing layer, of the conducting layer. The steel rail has the beneficial effects that the sound absorption layers make direct contact with the outer walls of the two sides of the steel rail body, a better noise absorption effect is achieved, the sound absorption layers are matched with the damping layers internally provided with mass blocks, the vibration and noise reduction effect is better, noise can be greatly reduced, and a reinforcing screw is rotated to drive an extrusion block to move downwards to extrude the inclined faces of the protrusions; and the protrusions can drive the moving plates and the inserting blocks to move, and the inserting blocks can be inserted into the reinforcing blocks reserved on the urban rail prefabricated slab.
本发明公开了一种城市轨道施工用装配式钢轨结构及其施工方法，包括钢轨本体，钢轨本体的外部设置有外护层，且外护层的内部设置有阻尼层，外护层的内壁上一体连接有加强筋，且加强筋插接在阻尼层的内部，阻尼层的内部设置有质量块，外护层内部设置有加强层，且加强层一侧的外壁上设置有传导层，传导层远离加强层另一侧的外壁上设置有吸音层。本发明有益效果吸声层直接与钢轨本体的两侧外壁接触，具有更好的吸收噪音效果，与内部设有质量块的阻尼层配合，使得减振降噪效果更好，能够大大降低噪音，转动加固螺丝带动挤压块下移对凸起的倾斜面挤压，能够使凸起带动移动板和插块移动，能够使插块插接在城市轨道预制板上预留的加固块内部。
