Elastic abutted seam for bridge widening structure and construction method of elastic abutted seam
The invention relates to an elastic abutted seam for a bridge widening structure and a construction method of the elastic abutted seam. The elastic abutted seam comprises a new and old bridge splicing structure longitudinal seam, and an elastic splicing seam is arranged on the longitudinal seam. The elastic abutted seam is characterized in that a stiffening steel butt strap is arranged on the longitudinal seam, rubber is arranged on the periphery of the steel butt strap, the steel butt strap is filled with elastic materials, the elastic materials are fixed to a bridge body through anchoring parts, and two ends are embedded and fixed through concrete. According to the seam splicing construction method, materials needed by seam splicing are all common building materials in the market and do not need to be specially made, installation is easy, construction is convenient, applicability is high, the problem that the vertical displacement difference is large when the new bridge and the old bridge are spliced can be thoroughly solved, and the seam splicing construction method can effectively prevent water and cracks structurally and is safe and durable.
本发明涉及一种用于桥梁拼宽结构的弹性拼缝及其施工方法。包括新老桥梁拼接结构纵缝，所述纵缝上设置有弹性拼缝，其特征在于所述纵缝上设置加劲钢搭板，钢搭板周围设置橡胶，钢搭板上填充弹性材料，所述弹性材料用锚固件与桥梁梁体固定，两端用混凝土嵌固。本发明所述的拼缝施工方法，拼缝所需材料均为市场常见建材，无需特制，安装简单，施工方便、适用性强，可彻底解决新老桥拼接时竖向位移差大的问题，且构造上能有效防水防裂，安全耐久。
