Construction method of novel bridge deck expansion joint structure
A construction method of a novel bridge deck expansion joint structure comprises the steps that a first rigid unit, an elastic unit, a second rigid unit, a third rigid unit and a fixing assembly are prefabricated; the first rigid units and the elastic units are alternately arranged on the two sides of the second rigid units to form a telescopic structure, and the two third rigid units are clampedon the two sides of the telescopic structure; the telescopic mechanism is pre-pressed according to the air temperature during construction, and then the third rigid unit and the telescopic mechanism are fixed through a fixing clamping plate; the telescopic structure is placed on a bridge expansion joint, the telescopic structure and the third rigid unit are fixed to a bridge through the fixing assembly, then the fixing clamping plate is detached, and when the bridge deck expansion joint stretches out and draws back, the first rigid unit and the elastic unit can slide back and forth on the twosides of the second rigid unit. According to the construction method, operations such as steel bar welding and cast-in-place cement concrete are not needed, construction is more convenient, and the construction period is shorter.
一种新型桥面伸缩缝结构的施工方法，包括：预制第一刚性单元、弹性单元、第二刚性单元、第三刚性单元和固定组件；将若干第一刚性单元和弹性单元在第二刚性单元两侧交替排列成伸缩结构，将两个第三刚性单元夹在伸缩架构两侧；根据施工时的气温对伸缩机构进行预压，之后用固定夹板固定住第三刚性单元和伸缩结构；将伸缩结构放置于桥梁伸缩缝上，通过固定组件将伸缩结构、第三刚性单元固定在桥梁上，之后拆除固定夹板，在桥面伸缩缝伸缩变化时，第一刚性单元和弹性单元可在第二刚性单元两侧来回滑动。本发明的施工方法，不需要焊接钢筋以及现浇水泥砼等作业，施工更加便捷、施工周期更短。
