支架形式的选择，应考虑现场施工条件与帽梁的高度还应考虑经济成本和尽量能就地取材。
The choice form, should consider the spot construction term and the high degree of the hat beam, should still consider the economic costs with can acquire necessary material locally to the best.
当“井”字梁结构外露，特别是梁的高度与宽度都较大时，对消防喷头的布置带来很大影响。
When the grillage beam structure is exposed outside, especially when the height and width of the beam are relatively large, the spray head layout will be greatly influenced.
再利用此模型，通过变换组合梁的高度和各钢板的厚度等参数比较分析梁的承载能力，应力，挠度的变化等。
Again USES the model, through transformation composite beam highly and various steel plates parameter comparative analysis beam and support capacity, stress, deflection change and so on.
