摘要： A prestressed pavement has apparatus to prestress the slabs, has slab abutments to resist the prestress force, has short-life friction-reducing medium to prevent the slab early cracking, has restraints to prevent the slab buckling, and has accumulators to control the prestress. The pavement does not need longitudinal tensile material, and can be built by continuous and one-time concrete casting. The prestressing is simple, fast, and may be delayed or made by stages. The techniques can be used to convert existing non-prestressed concrete pavements to prestressed pavements.
摘要翻译：预应力路面具有对板坯进行预应力的装置，具有抵抗预应力的板状基台，具有短寿命的减摩介质，防止板坯早期开裂，具有防止板坯屈曲的限制，并具有控制预应力的蓄能器。路面不需要纵向拉伸材料，可以通过连续和一次性混凝土浇筑来建造。预应力是简单，快速，可能会延迟或分阶段制作。这些技术可用于将现有的非预应力混凝土路面转换为预应力路面。

摘要： A concrete contraction and expansion joint with a mechanism providing adjustable height, enabling fast, efficient pouring of concrete over layout surfaces, achieving accurate thickness and desired slope of the concrete slab. In a preferred embodiment, the concrete section joint assembly (35) is pre-formed by using longitudinal sections having a channel (37) for holding elastomeric material (42), with the section supported from its underside by shaped support units, each mounted on two threaded studs (24). A specially designed nut (28) threaded on each stud (24) provides height adjustability and by rotation raises or lowers the height of support unit sides. The height adjustment, provided from above the assembly, can be performed before concrete pouring is completed and an upper edge portion of the elastomeric material or the upper edges of the channel are visible with the concrete surface, providing a reference height and slope for the concrete surface. Another embodiment provides a surface level guide for mortar or plaster work in wall finishing.
摘要翻译：具有可调节高度的机构的混凝土收缩和伸缩接头，能够快速有效地将混凝土浇注在布置面上，实现混凝土板坯的精确厚度和所需的坡度。在优选实施例中，通过使用具有用于保持弹性体材料（42）的通道（37）的纵向部分预先形成混凝土部分接合组件（35），其中该部分从其下侧由成形的支撑单元支撑，每个安装在两个螺柱（24）。在每个螺柱（24）上螺纹的专门设计的螺母（28）提供高度可调节性，并且通过旋转提升或降低支撑单元侧的高度。在混凝土浇注完成之前可以进行高度调节，并且弹性材料的上边缘部分或通道的上边缘与混凝土表面一起可见，为混凝土提供参考高度和坡度表面。另一实施例提供了用于墙面精加工中的砂浆或石膏工作的表面水平引导件。
