    摘要： A composite load bearing structure comprises a main body portion having a top surface and a bottom surface defining a dimension of thickness therebetween, first and second side surfaces defining a dimension of width therebetween, first and second end surfaces defining a dimension of length therebetween, and a first longitudinal axis oriented along the length of the main body portion. The thickness is significantly less than at least the length of the load bearing structure. The main body portion is made of a first composite material comprising a binding constituent in a proportion of about 10% to about 20% by volume, and an aggregate material in a proportion of about 80% to about 90% by volume. The binding constituent comprises polyethylene or a polyethylene blend having at least 10% polyethylene. The aggregate material is in the form of irregular multi-faceted pieces of crushed furnace slag, crushed gravel, crushed limestone, crushed granite, crushed basalt, crushed trap rock, and mixtures thereof, and the pieces of aggregate material are distributed and otherwise arranged within the main body portion so that opposed surfaces of the pieces of aggregate material have at least partial contact, one with another, in a contiguous manner. An inner strengthening member is disposed within the main body, and may comprise reinforcing bars; rolled, drawn, or cast ferrous sections; rolled, drawn, or cast composite alloy sections; plastic, metallic, and carbon based fibers; wire mesh, and expanded metal mesh.

    摘要： A rail-tie fastening assembly for connecting a rail having a rail flange to a tie comprising a rail seat assembly and a rail anchor. The rail seat assembly is connectible to the tie and includes an anchor slot and a seat hook assembly. The seat hook assembly is adapted to extend a distance over an upper surface of the rail flange. The rail anchor includes an anchor hook assembly adapted to extend over on the upper surface of the rail flange in an assembled position of the rail anchor to the rail seat assembly. The rail anchor is insertible through the anchor slot in the rail seat assembly to the assembled position. The seat hook assembly is spaced a distance from the upper surface of the rail flange to cooperate in permitting vertical movement of the rail in the assembled position of the rail anchor to the rail seat assembly. Tne anchor hook assembly engages one side of the rail flange and the seat hook assembly engages the opposite side of the rail flange to restrain lateral movement. A base anchor is connected to the rail seat assembly and the base anchor in disposable in a cavity formed in an upper surface of the tie and the base anchor is secured to the tie, thereby securing the rail seat assembly to the tie.

    摘要翻译： 一种用于将具有轨道法兰的轨道连接到包括轨道座椅组件和轨道锚固件的连接件的轨枕紧固组件。 轨道座椅组件可连接到系带并且包括锚定狭槽和座椅钩组件。 座椅钩组件适于在导轨凸缘的上表面上延伸一段距离。 轨道锚固件包括锚钩组件，其适于在轨道锚固件的组装位置延伸到轨道座椅组件的上表面上。 轨道锚固件可通过导轨座组件中的锚定槽插入到组装位置。 座椅钩组件与导轨凸缘的上表面隔开一段距离，以配合以允许轨道在轨道锚固件的组装位置中垂直移动到轨道座椅组件。 锚钩组件接合轨道法兰的一侧，并且座钩组件与轨道法兰的相对侧接合以限制横向运动。 基座锚固件连接到轨道座椅组件，并且基座锚固件一次性地连接在形成在系杆的上表面中的空腔中，并且基座锚固件固定到系带上，从而将轨道座椅组件固定到系带上。
