Equal-inner-section reinforced concrete box girder structure and prefabricating method
According to an equal-inner-section reinforced concrete box girder structure, an inner cavity of a box girder is provided with identical equal sections from the head end to the other end, and the portions, close to the two ends, of a web are gradually thickened outwards. The structure that a traditional reinforced concrete box girder is large in middle cavity and narrow in outlets in the two endscan be changed, mounting and dismounting of an inner mold during prefabrication are facilitated, and positioning of a steel bar protection layer can be effectively guaranteed.
等内截面钢筋混凝土箱梁结构，箱梁内空腔从头端到另一端为完全相同的等截面，腹板在接近两端部位向外逐渐加厚。本发明可改变传统钢筋混凝土箱梁中间空腔大，两头出口窄小的结构，有利于预制时内模的安装和拆除，并能有效的保证钢筋保护层的定位。
