Concrete column enlarged section reinforcing structure and construction method thereof
The invention relates to a concrete column section increasing reinforcing structure and a construction method thereof. The concrete column section increasing reinforcing structure comprises an original concrete column, newly-added vertical load-bearing steel bars, newly-added stirrups, a newly-added reinforced concrete surface layer and newly-added foundation bent bars. The diameter of the newly added vertical stressed steel bar is phi 14; the diameter of the newly added stirrup is not less than phi 8; the strength of the newly-added reinforced concrete surface layer is not smaller than the concrete strength of an original concrete column and an original foundation and is not lower than C30. The diameter phi of the newly added basic bending rib is not less than 12; the method has the most remarkable advantages that the concrete columns are adopted to enlarge the cross section to reinforce the structure, the overall shock resistance of the original structure can be improved, new and old structures jointly bear the earthquake action, and therefore the toughness of a house is enhanced, and structural collapse is prevented.
本发明涉及一种混凝土柱加大截面加固结构及其施工方法，包括原混凝土柱、新增竖向受力钢筋、新增箍筋、新增钢筋混凝土面层、新增基础弯筋；所述的新增竖向受力钢筋直径为φ14；所述的新增箍筋直径不小于φ8；所述的新增钢筋混凝土面层强度不小于原混凝土柱、原基础的混凝土强度，且不低于C30；所述的新增基础弯筋直径不小于φ12；本发明最显著的优势在于采用混凝土柱加大截面加固结构，可以提高原结构的整体抗震能力，使新旧结构共同承担地震作用，从而增强房屋的韧性，防止结构倒塌。
