Bridge expansion joint structure and construction method
The invention relates to the technical field of bridge expansion joints, in particular to a bridge expansion joint structure and a construction method. The structure comprises an expansion joint body, the expansion joint body comprises a bridge body, cement concrete and the like are laid on the top face of the bridge body, stirrups are embedded in the bridge body, reinforcing ribs are fixedly installed on the side faces of the middles of the stirrups, reinforcing bolts are fixedly installed on the rear sides of the stirrups, and impact-resistant bodies are fixed to the top faces of the reinforcing bolts through nuts. The impact force of a vehicle load is reduced through the impact-resistant bodies, and the service life of the expansion joint is prolonged; through the arrangement of the reinforcing bolts and the nuts, the construction difficulty of the expansion joint body is reduced, and the construction quality is improved; and the pouring type concrete is arranged on the top face of the expansion joint body, smooth transition between the pouring type concrete and bridge deck pavement asphalt concrete is achieved, vibration during driving is reduced, impact resistance is improved, driving noise is reduced, and driving comfort is improved.
本发明涉及桥梁伸缩缝技术领域，具体为一种桥梁伸缩缝结构及施工方法，包括伸缩缝本体，所述伸缩缝本体包括桥体，所述桥体的顶面铺设有水泥混凝土等，所述桥体内部预埋有箍筋，所述箍筋的中部侧面固定安装有加强筋，所述箍筋的后侧固定安装有加强螺栓，所述加强螺栓的顶面通过螺母固定抗冲击体。本发明通过抗冲击体减少车辆荷载的冲击力，延长伸缩缝的寿命；通过加强螺栓和螺母的设置，降低伸缩缝本体的施工难度，提高了施工质量；通过伸缩缝本体顶面设置浇注式混凝土，实现和桥面铺装沥青混凝土刚度的平稳过渡，减少行车时震动，提高抗冲击性，进而减小行车噪声，提高行车舒适性。
