载荷表数据说明 Load table data exploration (Show)
U=外加安全均布面载荷,单位kPa.  U=Sate uniformly distributed load in kPa.
C=加在正交于扁钢方向(垂直方向)上的安全外加线载荷,用千牛顿、米宽表示。
  C=Safe concemtrated load at vertical flat-steel direction in KN/m width.
D=变形挠度,单位mm。   D=deflection in mm
表中粗线左边各跨度相对就的挠度,在4kPa均匀载荷F小于5mm。
  Spans to the left of the heavy line in table produce a deflection of less than 5mm under a uniform load of 4kPa.
假定受荷扁钢是简单支承的无齿扁钢       Suppose bearing-bar flat-steel is simple supporting non-serrated flat-steel.
钢格板的自重计算是按无表面外理层考虑的。 The weights of the steel grating depends on finishing.
载荷是按许用挠曲应力171.6MPa(0.66Fy)计算的。  Load is calculated on the allowable deflection strength 171.6MPa.
经深加工的钢格板的重量会随装配、连接、附件、表面处理的增加而增加,例如,包边和热浸锌,使重量增加约一系列12%、二系列14%,三系列16%。
  The fabricated weights of steel-grating will increase, with the equipment, conjunction,additional part, finishing, such as edging.galvanizing
  This makes its weights increase 12-16%
