    • A combination expansion joint-seal having longitudinal frames made from aluminum extrusions extending longitudinally of an expansion joint for pavements and bridge decks. The expansion joint and seal are designed for joints of relatively small width and movement, e.g., between one-half inch minimum opening and 3 1/2 to 4 inches maximum opening. The longitudinal frames are mounted in new concrete or on previously laid pavement or bridge decks to be resurfaced with asphalt or other resurfacing material. The tread-seal is fixedly held in the longitudinal frames by elongated tongue and groove means and the joint space is spanned by at least one shallow, V-shaped, elastomer wall which deforms downwardly as the joint width becomes narrower.
    • 一种组合膨胀接头密封件,其具有由用于路面和桥面板的膨胀接头纵向延伸的铝挤压件制成的纵向框架。 膨胀接头和密封件设计用于相对较小宽度和运动的接头,例如最小开口的1/2英寸和最大开口31/2至4英寸之间。 纵向框架安装在新的混凝土或预先铺设的路面或桥面上,用沥青或其他表面重铺材料重铺。 胎面密封件通过细长的榫槽装置固定地保持在纵向框架中,并且关节空间被至少一个浅V形的弹性体壁横跨,随着接头宽度变窄,该密封件向下变形。

    • Modular expansion joint made from aluminum extrusions providing the longitudinal frames, longitudinal rails, and load-bearing support beams. The rails have an I-beam structure with downwardly and upwardly opening channels respectively receiving a lip of the frames and receiving and interlocking therein deformable longitudinal beads on the lower surface of an elastomer tread which completely covers and spans the joint. The load-bearing, length-variable beams extend through the rails, and coil springs are interposed between contiguous rails. The rails are composed of aligned rail segments with contiguous ends slidably spliced together.
    • 由铝挤压件制成的模块化膨胀接头,提供纵向框架,纵向导轨和承重支撑梁。 导轨具有工字梁结构,其具有向下和向上开口的通道,分别容纳框架的唇缘并且在弹性体胎面的下表面上容纳和互锁其中可变形的纵向珠,其完全覆盖并跨越接头。 承载的长度可变的梁延伸穿过导轨,并且螺旋弹簧介于连续的轨道之间。 轨道由对准的轨道段组成,其连续的端部可滑动地拼接在一起。
