预应力混凝土双T板结构性能检验方法探讨

Study on testing method for structural performance of prestressed concrete double Tplate

预应力混凝土双T板跨度长,自重大,结构性能检验要注意其特点,做好充分准备。要准备足够的辅助人员、场地、支墩、四个支座、吊装机械、足够的荷重块、、大量程百分表、加长杆表座。四个支座的圆钢直径和钢垫板的厚度要足够,圆钢的长度要等于试验结构构件肋宽。

A prestressed concrete double T plate has a longer span and heavy weight.The tester should pay attention to its characteristics.He must prepare fully for the testing. He must prepare a good field,two hard abanurus,four bearings,a hoisting machinery,enough load block,a wide range dialgage and a gauge stand with extension bar.
