Prefabricated assembled bridge expansion joint device and preservation construction method thereof
The invention discloses a preservation construction method for a polyurethane composite material composite structure prefabricated assembled bridge expansion joint, and relates to a bridge seamless expansion joint structure which comprises polyurethane inner filler and an assembly type polyurethane seamless expansion device. The bridge assembly type polyurethane seamless telescopic device comprises a telescopic framework, polyurethane prefabricated pouring and reliable connection between the telescopic device and a beam plate. The method mainly comprises two processes of prefabrication processing and field installation, and comprises the following steps: welding and positioning an angle steel assembly; comb tooth steel plates are machined, spliced and fixed; mounting a horizontal displacement control rod; mounting a template; pouring a polyurethane mixture; trimming a beam end area; welding an elevation control frame; splicing the telescopic device; pouring fiber concrete; and the wear-resistant layer is constructed and fully fused with the polyurethane reserved holes to form a mortise and tenon joint structure, and seamless connection is formed between the wear-resistant layer and the pavements on the two sides.
本发明公开了一种聚氨酯复合材料组合结构预制拼装桥梁伸缩缝的保全施工方法，涉及到桥梁无缝伸缩缝结构，桥梁无缝伸缩缝结构包括聚氨酯内填料和装配式聚氨酯无缝伸缩装置，所述桥梁装配式聚氨酯无缝伸缩装置包括可伸缩骨架，聚氨酯预制浇筑，伸缩装置与梁板的可靠连接。主要分为预制加工和现场安装两个流程，包括以下步骤：焊接定位角钢组件；梳齿钢板加工及对拼固定；水平位移控制杆安装；模板安装；聚氨酯混合料浇筑；梁端区域修整；标高控制架焊接；伸缩装置拼接；纤维混凝土浇筑；耐磨层施工与聚氨酯预留孔洞充分融合形成“榫卯”结构，并与两侧路面之间形成无缝连接。
