注:計(jì)算常用型材理論重量計(jì)算公式:
m=F×L×ρ
m—質(zhì)量Kg ;F—斷面積m2 ;L—長(zhǎng)度m ;ρ—密度*Kg/m3
☆其中:F斷面積計(jì)算方法:
1、方鋼F= a2
2、鋼管 F=3.1416×$(D-$) D—直徑 $—厚度
3、鋼板、扁鋼 F= a×$ a—寬度
密度:
鋼材:7.85*103 kg/m3
鋁:2.5~2.95*103
銅:8.45~8.9*103
鑄鐵:6.6~7*103
尼龍:1.04~1.15*103
鋼材分量
無(wú)縫鋼管鋼材的實(shí)際分量是按鋼材的公稱尺寸和密度(已往稱為比重)盤算得出的分量稱之為實(shí)際分量。這與鋼材 的長(zhǎng)度尺寸、截面面積和尺寸容許偏向有間接干系。因?yàn)殇摬脑谥圃鞖v程中的容許偏向,因而用公式盤算 的實(shí)際分量與實(shí)踐分量有肯定收支,以是只作為預(yù)算時(shí)的參考。
