Telescopic device used in reserved road expansion joint and construction method of telescopic device
The invention relates to the field of road construction, in particular to a telescopic device used in a reserved road expansion joint and a construction method thereof. The telescopic device comprises two oppositely-arranged toothed plates, wherein an expansion joint is formed between the two toothed plates; the toothed plates are connected with reinforced concrete panels on the two sides; the toothed plates are provided with fixing holes for steel bars in the reinforced concrete panels to penetrate through; a prestress multidirectional displacement system is arranged in the expansion joint and comprises a plurality of multidirectional expansion assemblies located in the expansion joint; each multidirectional telescopic assembly comprises sliding blocks slidably connected to the two toothed plates in the vertical direction, a telescopic rod hinged between the two sliding blocks in the horizontal direction and a first spring arranged on the outer side of the telescopic rod in a sleeving mode; and the two ends of the first spring are fixedly connected to the sliding blocks. The telescopic device has the effect of improving the stability between the reinforced concrete panels.
本发明涉及道路施工领域，尤其是涉及一种用于预留公路伸缩缝中的伸缩装置及其施工方法，其包括两块相对设置的齿板，两个齿板之间形成伸缩缝，所述齿板用于和两侧的配筋混凝土面板连接，所述齿板上开设有用于配筋混凝土面板内钢筋穿设的固定孔，伸缩缝内设置有预应力多向变位系统，所述预应力多向变位系统包括位于伸缩缝内的多个多向伸缩组件，多向伸缩组件包括沿竖直方向滑动连接在两块齿板上的滑动块、沿水平方向铰接在两块滑动块之间的伸缩杆、套设在伸缩杆外侧的第一弹簧，所述第一弹簧两端均固定连接在滑动块上。本申请具有提高配筋混凝土面板之间的稳定性的效果。
