鍍鋅格柵板承載力為什么？如何知道安全承載力的多少？為客戶更好的提供哪一種格柵板扁鋼？

客戶問：溝寬1500mm過4噸的車用什么規(guī)格的扁鋼？

客戶問：跨度2000mm經(jīng)過10車用什么規(guī)格的扁鋼？

客戶又問：溝寬50公分用30*3mm扁鋼做格柵板能過5噸的車嗎？

鍍鋅格柵板廠家采集整理資料貢獻(xiàn)給大家，最安全的條件下采購(gòu)熱鍍鋅鋼格柵板，以免發(fā)生意外。

承載力圖表中    C 為中心承載力(1千牛為單位）

                     U為均布承載力（1千牛為單位）

                     D為格柵板受外力的撓度(單位為毫米）

     荷載表的數(shù)值計(jì)算基于靜止荷載的材料強(qiáng)度設(shè)計(jì)值(對(duì)于碳素結(jié)構(gòu)鋼，強(qiáng)度設(shè)計(jì)值取170×10³ KN/m²)，包括考慮了鋼格板的重量。

    當(dāng)設(shè)計(jì)用于交通道路上的鋼格板時(shí)，還應(yīng)考慮沖擊和疲勞的因素。

   荷載表的數(shù)值計(jì)算根據(jù)承載扁鋼的公稱尺寸進(jìn)行的，如果承載扁鋼是負(fù)公差，應(yīng)當(dāng)考慮一個(gè)折減系數(shù)。同樣，

 

   承載扁鋼由于沖齒開孔開槽等造成截面尺寸的變化，都應(yīng)當(dāng)考慮折減
