Shrinkable fiber reinforced plastic rib for reinforced pavement
According to the shrinkable fiber reinforced plastic rib for the reinforced pavement, fiber bundles penetrate through isolating membranes for protection, and gaps are reserved between the isolating membranes according to the design length of fixed force transmission blocks. And a fixed force transmission block is arranged at the gap of the isolating membrane, is fixedly connected with the fiber bundle at the corresponding position, and is connected with the end part of the isolating membrane. The auxiliary tensioning ends are arranged at the ends of the fiber reinforced plastic ribs or arranged at intervals according to the designed distance. The arrangement depth control devices are arranged at the bottoms of the fixed force transmission blocks or the auxiliary tensioning ends, and for fiber reinforced plastic ribs of the single reinforced pavement, the arrangement depth control devices can be arranged in pairs or multiple. The system is low in manufacturing cost, easy to use, convenient to arrange and good in durability. The problem of water corrosion does not exist, synchronous deformation with a pavement base material is easy, and the peeling damage with concrete is not easy tooccur. New cracks caused by mismatching of modulus and deformation of the reinforcing ribs and the pavement base material in the temperature shrinkage process of the pavement base material are avoided, and the density of concrete temperature cracks is reduced.
一种用于配筋路面的可收缩纤维强化塑料筋，将纤维束穿过隔离膜保护，隔离膜间按照固定传力块的设计长度留出间隙。在隔离膜间隙处，设置固定传力块，固定传力块与相应位置纤维束固结，并同时连接隔离膜端部。辅助张紧端设置在纤维强化塑料筋端部或按设计距离间隔设置。布置深度控制装置设置在固定传力块底部或辅助张紧端处，对于单体配筋路面的纤维强化塑料筋，布置深度控制装置可成对或多个设置。本发明造价低，使用简单，布设方便，耐久性好。不存在水腐蚀问题，易于与路面基体材料同步变形，不易出现与混凝土的剥离病害。避免在路面基体材料温度收缩过程中由于强化筋与路面基体材料模量、变形不匹配而产生的新裂缝，降低混凝土温度裂缝的密度。
