计算负荷

用于指定美国宽翼缘梁尺寸的标准方法是例如W 6 x 25,其  深6英寸,重量为25 lb / ft

I形截面梁:

  • 英国:通用梁(UB)和通用柱(UC)
  • 欧洲:IPE。他。HL。高清和其他部分
  • 美国:宽法兰(WF)和H型截面

 

工字钢的理论重量计算公式

计算单位:kg/m

计算公式:W=0.00785×[hd+2t(b–d)+0.615(R2–r2)]

公式说明:h=高,b=腿长,d=腰厚,t=平均腿厚,R=内弧半径,r=端弧半径

计算举例:求250mm×118mm×10mm的工字钢每m重量。从金属材料手册中查出该工字钢t为13,R为10,r为5,则每m重量=0.00785×[250×10+2×13×(118–10)+0.615×(102–52)]=42.03kg

槽钢(kg / m)W = 0.00785×[hd + 2t(b – d)+0.349(R²–r²)]h =高度
b =腿的长度
d =腰的
厚度t =腿的平均厚度
R =内弧
半径r =端弧半径
每磅计算重量为80毫米×43毫米×5毫米的槽钢的重量。该槽钢的t为8,R为8,r为4,如在冶金产品目录中所见,则每m的重量= 0.00785×[80×5 + 2×8×(43 – 5 )+0.349×(82–4 2)] = 8.04kg
工字钢
(kg / m)
W = 0.00785×[hd + 2t(b – d)+0.615(R²–r²)]h =高度
b =腿的长度
d =腰的厚度
t =腿的平均厚度
R =内弧
半径r =端弧半径
计算尺寸为250mm×118mm×10mm的钢制I形梁的每m重量,这对I形梁为13,R为10,r为5,这可以在冶金材料手册中找到,然后,每平方米重量= 0.00785×[250×10 + 2×13×(118 –10)+0.615×(102 –5 2)] = 42.03kg

工字钢的形状和结构

工字钢由两个水平平面(称为法兰)组成,通过一个垂直组件或腹板连接。凸缘和腹板的形状形成“ I”或“ H”横截面。我的大多数横梁都使用结构钢,但有些是用铝制成的。诸如碳素结构钢和高强度低合金结构钢之类的金属结构具有不同的应用-例如建筑框架,桥梁和一般结构用途。

我的横梁具有各种重量,截面深度,法兰宽度,腹板厚度和其他用于不同目的的规格。订购工字钢时,买家根据其材料和尺寸对其进行分类。例如,一个11x20 I的光束的深度为11英寸,每英尺的重量为20磅。建筑商根据特定建筑物的需要选择特定尺寸的工字钢。建造者必须考虑许多因素,例如:

  1. 偏转。建造者将选择厚度以最小化梁的变形。
  2. 振动。选择一定的质量和刚度以防止建筑物振动。
  3. 弯曲。工字钢横截面的强度应适应屈服应力。
  4. 屈曲。选择法兰以防止局部,侧向或扭转屈曲。
  5. 张力。建造者选择的工字钢的腹板厚度在张力下不会失效,弯曲或起伏。

工字钢的设计使其能够在高应力下弯曲而不是弯曲。为了实现这一点,工字钢中的大多数材料都位于沿轴向纤维的区域中-承受最大应力的位置。理想的梁具有最小的横截面面积,需要尽可能少的材料,同时仍能达到所需的形状。

工字钢的用途

工字钢在钢结构建筑行业中具有多种重要用途。它们通常用作建筑物中的关键支撑桁架或主要框架。工字钢横梁以无穷的强度和支撑力确保结构的完整性。工字钢的强大功能减少了包含众多支撑结构的需要,既节省了时间和金钱,又使结构更加稳定。工字钢的多功能性和可靠性使它们成为每个建造者梦co以求的资源。

工字钢由于其高功能性而成为结构钢建造的首选形状。工字钢的形状使其非常适合平行于腹板的单向弯曲。水平凸缘抵抗弯曲运动,而腹板抵抗剪切应力。它们可以承受各种类型的载荷和剪切应力而不会弯曲。它们也具有成本效益,因为“ I”形是不使用多余钢材的经济设计。对于多种I光束类型,几乎可以满足任何要求的形状和重量。工字钢的通用功能是它的通用名称,即UB。

工字钢制造

当您需要工字钢用于任何类型的建筑应用时,请考虑使用钢梁制造以实现快速,高效和经济的订单履行。钢梁制造需要大量的经验,知识,辛勤的工作和专门的工具才能成功。不要只相信任何一家拥有我的公司。请与金利恒不锈钢加工厂联系以进行各种类型的定制焊接和金属加工。
