Novel expansion joint structure of continuous reinforced concrete pavement
The novel expansion joint structure comprises a left concrete block and a right concrete block, anchoring rib bodies are fixedly connected to the interiors of the left concrete block and the right concrete block, longitudinal profile steel is fixedly connected to the surfaces of the anchoring rib bodies, and anti-skid grooves are formed in the tops of the longitudinal profile steel; a connecting belt is fixedly installed between the left concrete block and the right concrete block, and a reinforced concrete sleeper beam is arranged at the bottom of the left concrete block. By adopting the expansion joint structure, the problem of thermal expansion of the concrete slab can be solved, the concrete slab can be freely expanded and contracted, the treatment mode of restraining internal force of the continuous reinforced concrete pavement expansion joint anchoring pier is changed, the defects of common anchoring piers are overcome, and the design and construction of the continuous reinforced concrete pavement are simplified; early damage of the continuous reinforced concrete slab and damage to adjacent structures due to jacking are avoided, the design of the anchoring part of the continuous reinforced concrete slab is greatly simplified, and investment is saved.
本发明公开了一种连续配筋混凝土路面新型伸缩缝结构，包括左混凝土块和右混凝土块，左混凝土块和右混凝土块的内部均固定连接有锚固筋体，锚固筋体的表面固定连接有纵向型钢，纵向型钢的顶部设置有防滑槽，左混凝土块和右混凝土块之间固定安装有连接带，左混凝土块的底部设置有钢筋混凝土枕梁，属于交通土建工程技术领域。本发明采用伸缩缝结构可消除混凝土板热胀伸缩问题，让其自由伸缩，改变连续配筋混凝土路面伸缩缝锚固墩约束内力的处理方式，消除常用锚墩缺陷，简化连续配筋混凝土路面设计及施工，避免了连续配筋混凝土板早期破坏及顶坏相邻结构物病害的发生，并大大简化了连续配筋混凝土板锚固部分设计，节约了投资。
