Vulcanization bonding vibration reduction fastener with low installation height
The invention provides a low-installation-height vulcanization bonding vibration reduction fastener which comprises a lower base plate, a middle layer and an upper base plate, and the lower base plate, the middle layer and the upper base plate are vulcanized into a whole through an adhesive. The lower base plate is of a fully-constrained frame structure, the upper base plate is embedded into the frame structure of the lower base plate, and the middle layer fills a gap between the lower base plate and the upper base plate. Outer shoulder structures are arranged at two ends of the lower base plate, inner shoulder structures are arranged at two ends of the upper base plate, and anti-pull-off limiting structures are arranged between the inner shoulder structures and the outer shoulder structures; a full-constraint structural design concept is adopted, the whole fastener adopts a frame embedded structural design, the low mounting height design of the fastener is realized, a retaining shoulder structure and an anti-pull-off limiting structure are adopted to realize full constraint on an upper iron base plate, the mounting height of the fastener can be effectively reduced by the full-constraint structure, and meanwhile, the stability of a track is greatly improved. Meanwhile, the middle layer is of a high-torsion nail column type structure, and the horizontal overturning effect can be effectively resisted through the staggered arrangement of the nail column type structure.
本发明提供了一种低安装高度硫化粘接减振扣件，包括下垫板、中间层和上垫板，其中下垫板、中间层、上垫板通过胶黏剂硫化为一体；下垫板采用全约束框架式结构，上垫板嵌入下垫板的框架结构内，中间层填充下垫板和上垫板的空隙。下垫板两端设置外挡肩结构，上垫板两端设置内挡肩结构，内挡肩结构和外挡肩结构之间设置防拉脱限位结构；采用全约束结构设计理念，扣件整体采用框架嵌入式结构设计，实现扣件低安装高度设计，采用挡肩结构和防拉脱限位结构实现对上铁垫板全约束，全约束结构可有效降低扣件安装高度，同时大大提高轨道稳定性。同时中间层采用高扭抗钉柱式结构，通过错列排布钉柱式结构，可有效抵抗水平向翻转作用。
