Height-limiting protective frame adopting light composite material cross beam
The invention belongs to the field of traffic infrastructures and particularly relates to a height-limiting protection frame adopting a light composite material cross beam. The frame comprises a crossbeam, two upright posts and two inclined struts, wherein the cross beam transversely penetrates through two stand columns supported on two sides of a road, bottom ends of the stand columns are fixedto a bottom foundation through anchor bolts, the two inclined struts are obliquely arranged on back faces of the two stand columns respectively and are perpendicular to a plane formed by the cross beam and the stand columns, top ends of the inclined struts are connected with the stand columns, and bottom ends of the inclined struts are fixed to a bottom foundation through anchor bolts, and the cross beam is made of a pultrusion continuous fiber reinforced foaming polyurethane composite material. The height-limiting protection frame has advantages of being light, high in strength, capable of absorbing energy, buffering and easy to install, besides the function of warning passing motor vehicles that the height exceeds the limit, energy generated by collision of the ultrahigh motor vehicles can be consumed, and the probability that casualties are caused by collapse of the cross beam is reduced as much as possible.
本发明属于交通基础设施领域，具体涉及一种采用轻质复合材料横梁的限高防护架，包括一根横梁、两根立柱和两根斜撑；所述横梁横穿支撑于道路两侧的两根立柱之上，所述立柱的底端通过锚固螺栓固定在底部基础上；两根斜撑分别倾斜设置在两根立柱的背车面，且垂直于所述横梁和所述立柱组成的平面，所述斜撑的顶端与所述立柱相连，所述斜撑的底端通过锚固螺栓固定在底部基础上；所述横梁采用拉挤成型的连续纤维增强发泡聚氨酯复合材料制成。本发明所述限高防护架具有轻质、高强、吸能缓冲、安装简单的优点，除了具有警示过往机动车高度超限的功能外，还可以消耗超高机动车撞击产生的能量，尽最大可能减小横梁倒塌致人伤亡的概率。
