  插拔护栏的简单介绍


  插拔护栏网是一种公路钢护栏,其结构是将原有护栏立柱分为上下两部分,上立柱的钢管下端套在下立柱的钢管上端内,有螺栓横穿其中,将上下立柱钢管连接在一起。它通过对下立柱的加强,即使用套管或者其他工艺来防止下部护栏立柱的变形,同时对上部立柱的局部减弱或全部减弱来控制护栏立柱的变形位置,这样虽力臂减小,但截面抗弯模量也同时减小,从而保证防撞等级不低于原标准设计。本护栏易于施工,在车辆碰撞后能够方便地更换,而且不但适用于土路肩,挡墙和桥梁等位置,还适用于各种形式的钢护栏本产品具有美观耐用,不变形,安装快捷,是一种较为理想的金属护栏产品。使用范围:主要用于公园/动物园围栏、校园/场区围界、道路交通隔离、临时隔离带。


  A simple introduction to the fence


  Plug the fence is a highway steel guardrail, the structure of the original column is divided into two parts, steel pipe is sheathed on the column in the column under the pipe in the upper end of the bolt, across which the upper and the lower column steel pipes are connected together. It is through the strengthening of the column, using the casing or other process to prevent the deformation of the bottom column, while local weakening of the top column or all weakened position to control the deformation of the guardrail column, so the moment arm is reduced, but the flexural modulus also decreased, so as to ensure the anti-collision level not less than the original design standard. The utility model is easy for construction, can be easily replaced in the vehicle collision, and is not only suitable for the soil shoulder, retaining wall and bridge position, also suitable for various steel guardrail this product is beautiful and durable, non deformation, quick installation, is an ideal metal fence products. Scope of application: mainly used in the park / zoo fence, campus / field area, road traffic isolation, temporary isolation belt.
