Beam column type steel guardrail opening structure
A beam column type steel guardrail opening structure comprises stand columns, cross beams, rotating sleeves, rotating bolts, connecting pins and a foundation, the stand columns are longitudinally arranged on the foundation at intervals and connected with the cross beams through the bolts, the cross beams are arranged in three or more rows in the height direction, and openings are formed between every two spaced stand columns. A plurality of rows of cross beams are longitudinally disconnected at the opening positions, and the ends of the cross beams are provided with vertically-through mounting grooves, rotary sleeves are clamped into the mounting grooves, a left rotary sleeve and a right rotary sleeve are arranged in each row, one end of one rotary sleeve is provided with connecting channel steel with the same cross section size as the cross beams, the connecting channel steel covers the end of the other rotary sleeve, and the two rotary sleeves are connected into a whole through a connecting pin. The rotating sleeve is connected with the cross beam through the rotating bolt and the limiting pin, and the rotating sleeve rotates to be perpendicular to or horizontal with the cross beam with the rotating bolt as the axis. The opening position of the guardrail meets the safety protection requirement of the bridge guardrail; the vertical opening structure is convenient for operators to quickly open and close; only an existing structure needs to be changed, manufacturing cost is low, and installation and construction are convenient.
一种梁柱式钢护栏开口结构，包括立柱、横梁、旋转套管、旋转螺栓、连接销、基础，所述立柱纵向间隔设基础上，通过螺栓与横梁连接，横梁在高度方向设三至多排，开口设在间隔的两立柱间，若干排横梁在开口位置纵向断开且端部设上下贯通安装槽，旋转套管卡入安装槽，每排设左右两个旋转套管，一个旋转套管一端设与横梁横截面尺寸相同的连接槽钢，盖在另一旋转套管端部，通过连接销将两个旋转套管连为整体，旋转套管与横梁通过旋转螺栓和限位销连接，旋转套管通过旋转螺栓为轴心转动至与横梁垂直或水平。护栏开口位置满足桥梁护栏安全防护需求；竖向开口结构方便作业人员快速开启和关闭；仅需改动已有结构，低造价，方便安装施工。
