Partial prefabricated reinforcing structure of existing H-shaped steel column and construction process thereof
The invention discloses a partial prefabricated reinforcing structure of an existing H-shaped steel column. The structure comprises the existing H-shaped steel column, prefabricated concrete sections,horizontal pull rods and a grouting material. The plurality of prefabricated concrete sections are stacked one by one in two semi-closed cavities defined by flanges and a web of the existing H-shapedsteel column; the horizontal pull rods are arranged in the longitudinal direction of the existing H-shaped steel column at a certain interval, and the two ends of the horizontal pull rods are respectively welded with the two flanges of the existing H-shaped steel column; a formwork is adopted to wrap the existing H-shaped steel column, and then the grouting material is filled with the gaps between the H-shaped steel column and the prefabricated concrete sections; and after the formwork is removed, partial prefabricated reinforcing columns are formed. The invention further discloses a construction process of the partial prefabricated reinforcing structure of the existing H-shaped steel column. The prefabricated concrete sections are convenient for industrial production and high in construction efficiency; and the grouting material can combine the prefabricated concrete sections and the existing H-shaped steel column into a whole, so that the bearing capacity of an original component isremarkably improved.
本发明公开了一种既有H型钢柱的部分预制加固结构，包括：既有H型钢柱、预制混凝土节段、水平拉杆和灌浆料。将若干预制混凝土节段逐个叠放在既有H型钢柱的翼缘与腹板围成的两个半封闭空腔内。沿既有H型钢柱纵向按一定间隔设置水平拉杆，将水平拉杆两端分别与既有H型钢柱的两块翼缘板焊接。采用模板将既有H型钢柱包裹起来，随后向既有H型钢柱与预制混凝土节段之间的空隙填充灌浆料。撤去模板后即形成部分预制加固柱。本发明还公开了上述既有H型钢柱部分预制加固结构的施工工艺。本发明采用的预制混凝土节段，工厂化制作方便，施工效率高。灌浆料可将预制混凝土节段与既有H型钢柱组合成整体，显著提升原构件的承载能力。
