摘要： According to one aspect of the invention there is provided a prefabricated rail sleeper [10] suitable for use in erecting a track structure [30]. The rail sleeper [10] comprises an elongate body portion [12] for supporting rails [14], the body portion [12] including a top surface [12,1], a bottom face [12.1] and at least two side faces [12.3], and terminating at least at one end thereof in a transition joint formation [16] dimensioned matingly to engage a complimentarily dimensioned transition joint formation [16] of an adjacent rail sleeper [10] in use so as to form a substantially continuous track structure. The sleeper [10] also includes a series of block formations [20], each of which is at least partially outwardly flared and extending beyond the side faces [12.3] of the body portion [12] so as to increase shear interlock of the sleeper [10] with the track bed to reduce longitudinal creep; as well as a series of transverse drainage ducts [26] extending underneath the rail sleeper [10] for allowing rainwater drainage between different side faces [12.3] of the body portion [12] and away from the rail sleeper. The invention extends to a ballast-free track structure [30] comprising at least two rail sleepers [10] according to the invention wherein the sleepers are located in spaced parallel orientation on a ballast-free track bed so as to define a centre drain [32] between the sleepers; and including a mesh [34] located between the sleepers [10] for reinforcing the centre drain [32].

摘要： In a prestressed concrete cross tie, a layer of steel reinforcements are located at or near the neutral axis of the cross tie section to minimize fatigue stress fluctuations. Deviation from the neutral axis is not great enough to cause stress fluctuations to exceed the endurance limit of the material. Because fatigue failure of prestressed concrete members is principally associated with reinforcement failure, increased fatigue life of the cross tie is achieved.
摘要翻译：在预应力混凝土十字架中，一层钢筋加固件位于交叉连接部分的中性轴线处或附近，以最小化疲劳应力波动。与中性轴的偏差不足以引起应力波动超过材料的耐久极限。由于预应力混凝土构件的疲劳破坏主要与加固失效有关，因此可以提高十字架的疲劳寿命。

摘要： A concrete pouring form accessory includes a post which supports a slidably removable sleeve and insert threaded thereto in a mold or pouring form during pouring of a concrete railroad tie. Following hardening of the railroad tie, the tie is readily slidably removed from the support post thereby leaving the sleeve disposed within the insert to protect threads of the insert until the sleeve has been unscrewed from the insert (usually at the time of bolting rails to the railroad tie). A resilient annular cone-shaped sealing element forms a plug behind the insert and sleeve to preclude the application of blocking concrete behind the sleeve and the support post.

摘要： A fiber-reinforced prestressed reinforced concrete sleeper is integrally cast and includes a sleeper body and two rail bearing regions. A rail clamping base is arranged on a surface of the each rail bearing region. The two rail bearing regions are located under rails on both sides of the sleeper and the two rail bearing regions are located above the sleeper body. A reinforcing fiber is mixed into the two rail bearing regions only, and a reinforcing rib is arranged in the sleeper body. The reinforcing fiber is concentrated in a main stress region under the surface of the rail bearing regions. The reinforcing fiber arranged in a region with a large stress is more than the reinforcing fiber arranged in a region with a small stress.

摘要： Prestressed concrete railroad ties are formed in molds which are supported by existing track near the area where they are to be installed. Each mold will form a number of ties. Reinforcement strands are located within a plurality of longitudinally spaced molds. Concrete is then poured into the molds and the ties are formed bottoms up in the molds. A group of ties are simulatenously removed from a given mold by a special extractor which first simultaneously clamps the reinforcing strands extending outwardly from a given mold, and then lifts the strands as a group from the mold by a suitable crane. Preferably the center of gravity of ties is spaced from a pivot point which will cause 180.degree. rotation locating the ties in upright position to be loaded on a railway car or other vehicle to take them to the site where they are to be installed.

摘要： An improved concrete product formed with an attachment device of a type having female threads adapted to cooperate with the threaded ends of bolts or the like inserted thereto. The threads are continuously protected by a sealed plug until ready for use. The interior of the plug serves further the purpose of readily releasing the precast body of concrete from its pouring form. Thus, when the product is ready for use, it is a simple matter to merely drive a screwdriver into the plastic sleeve and unscrew same from insert 17.
