Prestressed steel strand reinforced concrete beam structure
The invention discloses a prestressed steel strand reinforced concrete beam structure which is characterized in that a steel beam is arranged below a concrete beam, the steel beam is a steel channel,a main bar of the concrete beam is welded to the steel beam, a central bearing point steel strand is arranged in a midspan position of the concrete beam, the central bearing point steel strand is located in the middle of the section of the concrete beam, a steel anchored hoop connected to the central bearing point steel strand is arranged in a position 600-700 mm above a concrete floorslab, the concrete beam is provided with side bearing point steel strands in a 1/4 position and a 3/4 position along a span direction, the side bearing point steel strands penetrating a pre-penetrated hole and areserved hole of the concrete floorslab are fixed to the steel anchored hoop, and the steel anchored hoop connected to the side bearing point steel strands is arranged in a position 300-400 mm above the concrete floorslab.
本发明公开了一种预应力钢绞线加固混凝土梁结构，其特征是在混凝土梁下面设置钢梁，钢梁采用槽钢，混凝土梁的主筋与钢梁焊接，混凝土梁跨中位置设置中支点钢绞线，中支点钢绞线位于混凝土梁截面中部，与中支点钢绞线联接的钢锚固箍设置在混凝土楼板上方600～700mm位置，混凝土梁沿跨度方向1/4位置和3/4位置均设置边支点钢绞线，边支点钢绞线穿过预穿孔和混凝土楼板预留孔固定在钢锚固箍，与边支点钢绞线联接的钢锚固箍设置在混凝土楼板上方300～400mm位置。
