Built-in sleeve grouting connecting steel pipe concrete superposed column and construction method thereof
The invention discloses a built-in sleeve grouting connecting steel pipe concrete superposed column and a construction method thereof, and relates to the technical field of steel pipe concrete superposed column grouting connection. After an upper exposed center steel pipe and a lower exposed center steel pipe of the steel pipe concrete superposed column are grouting and connected through a steel pipe butt joint sleeve, a middle outer pouring concrete layer is poured outside the steel pipe butt joint sleeve, and the steel pipe butt joint sleeve wraps the interior of the middle outer pouring concrete layer. The middle outer pouring concrete layer is good in fire resistance and corrosion resistance, and the service life of the prefabricated steel pipe concrete superposed column is effectivelyprolonged.
本发明公开一种内置套筒灌浆连接钢管混凝土叠合柱及其施工方法，涉及钢管混凝土叠合柱灌浆连接技术领域，该内置套筒灌浆连接钢管混凝土叠合柱的上外露中心钢管和下外露中心钢管通过钢管对接套筒灌浆连接后，在钢管对接套筒的外部浇筑中部外浇混凝土层，钢管对接套筒包裹于中部外浇混凝土层内部，中部外浇混凝土层抗火及抗腐蚀性能好，有效延长了预制式钢管混凝土叠合柱的使用寿命。
