今天由本人为大家讲述一下的零部件，护栏板的零部件一共有6种，分别是立柱、防组块、护栏板托架、端头、立柱防雨帽与螺栓。 Today by me for everybody about parts of rail, guardrail plate parts a total of six, respectively is the pillar, anti block, guardrail plate bracket, end, column rain proof hat and bolt. 每个零部件的作用都非常重要，缺少哪种零部件都不能达到有效的防护效果。下面我们一一介绍每个零部件的作用。 The role of each component is very important, the lack of which parts can not achieve effective protective effect. Below we one one introduce the role of each component. 护栏板立柱可分为镀锌立柱、浸塑立柱、法兰立柱、普通立柱等。立柱的直径有多种，可根据工程需求选择合适的直径与厚度。护栏板固定在路基上，与路基和为一体达到共同防护的效果。 The column can be pided into galvanized column, dip plastic column, flange column, the general column, etc.. The diameter of the column is varied, and the diameter and thickness can be selected according to the demand of the project. The fence board is fixed on the roadbed, and the roadbed and the effect of the common protection are achieved. 护栏板立柱防雨帽的作用也非常重要，如果没有防雨帽，立柱里面会积压很多雨水，雨水有很多酸性离子，即使防腐效果再好的立柱，长期下来也会飞腐蚀。 Guardrail column rain hat is also very important, if there is no rain hat, inside the post will backlog a lot of rain, rain a lot of acidic ion, even if again good antiseptic effect of column, come down for a long time will also fly corrosion. 护栏板防组块与托架一般选择其一，将护栏板与立柱链接在一起，防组块的防护效果要高于托架，因为防组块的变形幅度更大，通过零部件的变形来减缓汽车的动力。 Block and the bracket generally choose the protection of guardrail plate, guardrail board and post links together, anti block the protective effect to be higher than the bracket, because of the greater anti block deformation amplitude, through the deformation of parts to slow down the car. 护栏板端头的使用量比较小，在每组护栏板的两头安装一个，让每组护栏板看起来更加美观。 The use of the end of the fence plate is relatively small, in each of the two sides of the fence board to install one, so that each of the fence board looks more beautiful. 螺旋就不用介绍了，主要介绍一下螺栓的防腐性能也非常重要，防腐性能好的螺栓可以更大程度上提高护栏板的使用寿命 The guard rail board screw does not need to introduce, mainly introduces the bolt's anticorrosion performance is also very important, the anti corrosion performance of the bolt to a greater extent, improve the service life of the fence board
