Polyurethane concrete bridge deck continuous structure
The invention discloses a polyurethane concrete bridge deck continuous structure which is characterized in that inclined planes are arranged at the ends of main beams, inverted-cone-shaped bases are arranged between bridge deck concrete layers on the two main beams, the inverted-cone-shaped bases abut against the inclined planes, leveling base plates are arranged above the inverted-cone-shaped bases, cushion blocks are fixedly arranged at the tops of the inverted-cone-shaped bases, damping spring columns are arranged on the cushion blocks in a sleeving mode, and the damping spring columns are arranged on the damping spring columns in a sleeving mode. The two ends of the damping spring columns abut against the inverted-cone-shaped base and the leveling base plate respectively, the polyurethane concrete pavement layer is laid on the leveling base plate, and a kerf at the connecting position of the polyurethane concrete pavement layer and the bridge deck concrete layer is filled with oil-immersed battens. According to the polyurethane concrete bridge deck continuous structure, the polyurethane concrete pavement layer is arranged, so that the polyurethane concrete bridge deck continuous structure is high in strength, small in elastic modulus and excellent in compression resistance and fracture resistance, cracks are not prone to being generated when the polyurethane concrete bridge deck continuous structure is affected by vibration of a beam plate or thermal expansion and cold contraction, and therefore the driving safety can be guaranteed.
本发明公开了一种聚氨酯混凝土桥面连续结构，主梁的端部设置有斜面，两个主梁上的桥面砼层之间设置有倒锥型底座，且倒锥型底座与斜面抵接，倒锥型底座上方设置有找平垫板，垫块固设于倒锥型底座顶部，减震弹簧柱套设于垫块上，且减震弹簧柱两端分别与倒锥型底座和找平垫板抵接，聚氨酯混凝土铺装层铺设于找平垫板上，聚氨酯混凝土铺装层与桥面砼层连接处的切缝内填充有浸油木条。本发明提出的一种聚氨酯混凝土桥面连续结构，通过设置聚氨酯混凝土铺装层，其强度高、弹性模量小，并有着优异的抗压和抗折性能，在受到梁板的振动或热胀冷缩的影响时不易产生裂缝，从而能够保证行车的安全性。
