construction section steel的意思|示意

It's large size of section, a mass of consumption of concrete and reinforcing steel bar, and uncertain factors, cause notable difficulty to the construction and quality control of transfer floor.

同时转换层截面尺寸大，混凝土和钢筋的用量都非常大，且施工过程中的不确定性因素多，给转换层的施工及其质量控制带来了很大的难度。

The main construction of the machine is section steel bar with sheet metal cover.

设备主要结构采用钢方通及钣金件。

Following the process of construction, considering the worst loads, according to the assumption of plane section, the steel girder alone and the composite girder are computed respectively.

按照实际施工过程，考虑最不利计算荷载，根据平截面假定，分别对钢梁单独受力和钢-混凝土组合梁两种工况进行计算。
