Concrete pouring construction method for fabricated steel structure building foundation

The invention discloses a concrete pouring construction method for a fabricated steel structure building foundation, which comprises the step of installing a concrete pump pipe to construct a concrete pump pipe supporting structure of the fabricated steel structure building foundation. The inverted triangular cone is hooked on the longitudinal reinforcing steel bars on the lower portion of the surface bars through the barbs so that the inverted triangular cone can be flexibly adjusted in the environment of the bundled surface bars to support the concrete pump pipe, and the problem that the gravity of a concrete pier is large, and the concrete pier cannot be flexibly adjusted in the environment of the bundled surface bars to support the concrete pump pipe conveniently is solved. 本发明公开了一种装配式钢结构楼体基础的混凝土浇筑施工方法，包括进行混凝土泵管安装步骤，构建出装配式钢结构楼体基础的混凝土泵管支撑结构。倒立三角椎通过倒钩勾在面筋下部的纵向钢筋上能便于在捆扎好的面筋环境中进行灵活调整来进行支撑混凝土泵管，解决了混凝土墩重力较大，存在不便于在捆扎好的面筋环境中进行灵活调整来进行支撑的问题。
