    • Modular expansion joints made from aluminum extrusions providing longitudinal frames and longitudinal rails. The rails have an Ibeam-like structure with upwardly opening channels respectively receiving and interlocking therein deformable beads on the lower surface of an elastomer tread with hollow, V-sections deforming downwardly as the joint width becomes narrow. The elastomer tread completely covers and spans the joint. The longitudinal rails are supported by solid load-bearing beams having a greater width than depth, and coil springs are interposed between contiguous rails.
    • 由铝挤压件制成的模块化伸缩接头,提供纵向框架和纵向导轨。 轨道具有I形梁状结构,其具有向上开口的通道,分别在弹性体胎面的下表面上接收和互锁可变形的胎圈,并且随着接头宽度变窄,中空的V形部分向下变形。 弹性体胎面完全覆盖并跨越接头。 纵向轨道由具有比深度更大的宽度的固体承载梁支撑,并且螺旋弹簧插入在相邻轨道之间。
