Assembly type bridge guardrail
The invention relates to the technical field of bridge anti-collision guardrails, in particular to an assembly type bridge guardrail which is installed on a bridge deck. The assembly type bridge guardrail comprises a plurality of connecting screw rods arranged in parallel and penetrating the bridge floor, connecting columns, and a guardrail body; the connecting columns are of hollow structures, the connecting columns are installed on the bridge floor through the connecting screw rods, a positioning bolt is installed in a cavity of each connecting column, the positioning bolts and the connecting columns are coaxially arranged, and the positioning bolts extend out of the connecting columns from the tops of the connecting columns; connecting sleeves are installed on the guardrail body and arranged on the connecting columns in a sleeving mode, the inner diameters of the connecting sleeves are larger than the outer diameters of the connecting columns, and first concrete is poured between the connecting sleeves and the connecting columns. In the bridge guardrail mounting process, only holes need to be punched in an existing bridge deck; meanwhile, the inner diameters of the connecting sleeves are larger than the outer diameters of the connecting columns, the requirement for the hoisting precision of the guardrail body is low, mounting is more convenient, construction is easy, and theconstruction period for mounting the bridge guardrail on an existing bridge can be shortened.
本发明涉及桥梁防撞护栏技术领域，具体涉及一种装配式桥梁护栏，安装在桥面上，包括：连接螺杆，平行设置有多个，连接螺杆贯穿桥面设置；连接柱，为空心结构，连接柱通过连接螺杆安装在桥面上，连接柱的空腔内安装有定位螺栓，定位螺栓与连接柱同轴设置，且定位螺栓从连接柱顶部延伸至连接柱外；护栏本体，护栏本体上安装有连接套筒，连接套筒套设在连接柱上，且连接套筒的内径大于连接柱的外径，连接套筒与连接柱之间浇筑有第一混凝土。在安装桥梁护栏过程中，只需在已有的桥面上打孔即可，同时连接套筒的内径大于连接柱的外径，对护栏本体的吊装精度要求较低，安装更加方便，施工简单，能够缩短在已有桥梁上安装桥梁护栏的施工工期。
