UHPC formwork-concrete filled steel tube composite short column and construction method thereof
The invention discloses a UHPC formwork-steel pipe concrete composite short column which comprises a steel bottom plate, a core steel pipe welded to the top of the steel bottom plate and core concrete poured in the core steel pipe, a reinforcement cage and a UHPC outer wrapping formwork are further arranged at the top of the steel bottom plate, and interlayer concrete is poured between the reinforcement cage and the UHPC outer wrapping formwork. Embedding holes are axially symmetrically formed in the top of the steel bottom plate, a vertical steel pipe is embedded in the steel bottom plate, a chemical adhesive is arranged in the vertical steel pipe, and a glass cover is fixedly connected to the top of the vertical steel pipe. When the steel reinforcement cage is installed, the outer-layer vertical steel reinforcement ring and the inner-layer vertical steel reinforcement ring in the steel reinforcement cage can be aligned with the embedding holes, the glass cover is crushed and enters the vertical steel pipes, and therefore chemical adhesives are distributed between the steel reinforcement cage and the vertical steel pipes and between the steel reinforcement cage and the embedding holes; and the dried chemical adhesive can stabilize the reinforcement cage outside the core steel pipe, so that the reinforcement cage does not need to be welded for multiple times to influence the outer side structure of the core steel pipe.
本发明公开了一种UHPC模板‑钢管混凝土叠合短柱，包括钢底板、焊接在钢底板顶部的核心钢管和浇筑在核心钢管内部的核心混凝土，钢底板的顶部还设置有钢筋笼和UHPC外包模板，钢筋笼和UHPC外包模板之间浇筑有夹层混凝土，钢底板的顶部轴对称开设有嵌入孔，钢底板的内部嵌装有竖钢管，竖钢管的内部设置有化学粘接剂，竖钢管的顶部固定连接有玻璃盖。本发明在安装钢筋笼时，钢筋笼中的外层竖钢筋圈和内层竖钢筋圈能够与嵌入孔对齐、压破玻璃盖并进入竖钢管的内部，从而使得化学粘接剂分布于钢筋笼与竖钢管之间以及钢筋笼与嵌入孔之间，而干化后的化学粘接剂能够将钢筋笼稳固在核心钢管的外部，无需对钢筋笼进行多次焊接而影响核心钢管的外侧结构。
