Metal guardrail with high impact resistance
The invention discloses a metal guardrail with high impact resistance. The guardrail is characterized in that two same upright posts are fixedly connected to two sides of a bottom plate, a top plate is fixedly connected to the tops of the upright posts, five parallel handrails are fixedly connected to the top of the bottom plate, the tops of the handrails are fixedly connected with the bottom of the top plate, and four same rollers are arranged on the front surfaces of the handrails; and bearings are fixedly connected to the two ends of each roller. An arranged buffer filling layer can play arole in buffering when the guardrail is impacted, meanwhile, the rollers can rotate when the guardrails are impacted, impact force is decomposed into force in the tangential direction of impact pointsof the rollers and acting force on the guardrails, the force borne by the guardrails is greatly reduced, and anti-cracking strips on the outer walls of the upright posts can protect the upright posts, the upright posts are prevented from being collided and scratched, meanwhile, the supporting effect can be achieved when the upright posts are collided, and therefore the effect of being high in impact resistance is achieved.
本发明公开了一种抗冲击能力强的金属护栏，底板的两侧固定连接有两个相同的立柱，立柱的顶部固定连接有顶板，底板的顶部固定连接有五个相互平行的栏杆，该栏杆的顶部与顶板的底部固定连接，栏杆的正面设置有四个相同的滚筒，所述滚筒的两端固定连接有轴承。通过设置的缓冲填充层能够在护栏受到撞击时，起到一个缓冲的作用，同时滚筒还可以在受到撞击时转动，将受到撞击地力分解为滚筒撞击点相切方向的力以及对护栏的作用力，大大减小了护栏所受到的力，且立柱外壁的防裂条能够对立柱进行保护，防止被磕碰划伤的同时，又能够在立柱受撞击时起到支撑的作用，以达到抗冲击能力强的效果。
