    Abstract: An expansion dowel includes an axially elongated sleeve-shaped dowel body slit in the axial direction from the leading end. A spiral-shaped expansion body is located in the dowel body in the axially extending region of the slit. By axially displacing the expansion body toward the leading end of the dowel body it widens radially outwardly and in turn expands the axially slit region of the dowel body providing the required anchoring effect.

    Abstract translation: 膨胀销包括从前端沿轴向方向的轴向细长的套筒形定位销主体狭缝。 螺旋形膨胀体位于狭缝的轴向延伸区域中的定位销主体中。 通过将膨胀体朝向销钉体的前端轴向移位，其径向向外变宽，并且进一步扩大销钉体的轴向狭缝区域，从而提供所需的锚固效果。

    Abstract: A spike retainer which may be forcibly driven through an aperture in a tie plate into a wood cross tie includes an upper lip for engaging a flanged base of a rail supported by the tie plate. A movable wedge attached to the spike retainer is forced between the cross tie and the tie plate when a spike is forcibly inserted into the spike retainer, thereby clamping the tie plate and the flanged base of the rail between the upper lip and the movable wedge. The spike retainer is initially inserted into a pre-drilled hole in the cross tie by means of an insertion tool having a channel which permits the spike retainer to be forcibly inserted into the hole without engaging the movable wedge.

    Abstract translation: 可以被强制地通过连接板中的孔驱动成木制十字架的钉保持器包括用于接合由连接板支撑的轨道的带凸缘的基座的上唇缘。 当钉被强制地插入到钉保持器中时，附接到钉保持器的活动楔被强制在十字架和连接板之间，从而将连接板和带凸缘的基座固定在上唇缘和活动楔之间。 尖钉保持器通过具有通道的插入工具最初插入十字架中的预钻孔中，该通道允许尖钉保持器被强制插入孔中而不与活动楔接合。

    Abstract: A railroad spike retainer is disclosed which may be driven into a railroad tie together with the spike it retains. The retainer exerts a retention force both against the spike to prevent its regression from the retainer and also against the tie to prevent the regression of the retainer itself from the tie.

    Abstract: The fastener has a spirally wound anchor sleeve which is circumferentially expanded within its mounting hole by inserting into the sleeve an anchor bolt or screw having a cross-section larger than the initial internal peripheral outline of the sleeve thereby locking the sleeve to the surrounding wall material. Initial grip of the sleeve in the mounting hole is provided and locking is further strengthened by providing on the outside of the sleeve teeth which bite into the wall material when the sleeve is inserted and expanded.
