波形护栏为什么是“波形”的

发布时间:2020-09-21 11:13:56人气:
  常见的高速公路护栏大多都是采用波形板为主材制作而成,也就是我们常说的高速波形护栏。那么这种护栏为什么用采用“波形”这种奇怪的板材制作高速公路护栏呢?
 
  波形板,顾名思义就是形状像波浪一样的金属板材,这是一种镀锌钢材,可以保证护栏在室外条件下拥有很长的使用寿命。
 
  而之所以采用这种板材,主要有以下两个方面的原因。其一:波形板拥有更好的强度和抗冲击能力。我们可以通过一个小实验进行证明,一张平面的硬纸板并不能承受多大的重量,很轻易的就会变形。但是将其折叠为波浪形之后,就可以承受数倍的重量。这是一种物理结构上带来的好处。
 
  其二:节约材料。在达到防撞要求的前提下,波形护栏可以节约更多的材料。高速护栏使用广泛,这样可在根本上节约成本并保证防撞性能。
 
  The common highway guardrail is mostly made of corrugated board,which is what we often call high-speed corrugated guardrail.So why is this kind of guardrail made of such strange plates as"waveform"?
 
  Corrugated board,as the name implies,is a kind of metal plate with wave like shape.It is a kind of galvanized steel,which can ensure that the guardrail has a long service life under outdoor conditions.
 
  The reason why this kind of plate is used is mainly due to the following two aspects.One:corrugated plate has better strength and impact resistance.We can prove through a small experiment that a flat piece of cardboard can't bear much weight and will easily deform.But when folded into a wavy shape,it can bear several times the weight.This is a physical structural benefit.
 
  Second,saving materials.On the premise of meeting the anti-collision requirements,the corrugated guardrail can save more materials.High speed guardrail is widely used,which can fundamentally save cost and ensure anti-collision performance.
