Bridge expansion joint structure and bridge expansion joint structure construction method
The invention discloses a bridge expansion joint structure and a bridge expansion joint structure construction method. The bridge expansion joint structure comprises an asphalt layer, a rubber layer, an air bag, a concrete layer and a base. The rubber layer is connected with the concrete layer through the base, the air bag is located in a first gap between the two ends of the rubber layer and the concrete layer, and the asphalt layer is connected to the upper surface of the rubber layer and located on the upper surface of the air bag, so that the rubber layer of the bridge expansion joint structure can be prefabricated, and the field operation time is shortened; a first gap between the rubber layer and the concrete layer is sealed through an air bag, so that the sealing effect is similar to that of an elastic material solidified on site; the rubber layer and the asphalt layer are combined, so that a steel plate does not need to be embedded in the rubber layer to support vehicles on the bridge floor, the section of the rubber layer is simple in shape and not prone to water accumulation, a good invisible effect is achieved through covering of the asphalt layer, and the technical defects in the prior art are overcome. The bridge expansion joint structure construction method is used for constructing the bridge expansion joint structure.
本发明公开了一种桥梁伸缩缝结构及桥梁伸缩缝结构施工方法，该桥梁伸缩缝结构包括沥青层、橡胶层、气囊、混凝土层、底座。橡胶层通过底座和混凝土层相连接，气囊位于橡胶层的两端和混凝土层之间的第一缝隙，沥青层连接于橡胶层的上表面，并位于气囊的上表面，使得该桥梁伸缩缝结构的橡胶层可以预制，减少了现场作业工时；且橡胶层和混凝土层之间的第一缝隙通过气囊密封，使得其密封效果与现场凝固的弹性材料近似；橡胶层和沥青层结合，使得橡胶层内无需预埋钢板来对桥面车辆提供支承，橡胶层的截面形态简单不易积水，沥青层的覆盖又带来了良好的隐形效果，避免了现有技术的技术缺陷。该桥梁伸缩缝结构施工方法用于施工该桥梁伸缩缝结构。
