Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of building construction, specifically relates to a support suitable for one-time installation of stiff steel column and column foot anchor bolt. BACKGROUND

[0002] In the current field of building construction, steel column installation as a crucial basic link, its traditional construction technology depends on the method of column bottom secondary grouting. Specifically, in the actual operation process, first, the initial pouring operation of foundation concrete needs to be completed. After the initial pouring concrete gradually coagulates until reaching the specified strength grade, the construction team can start the installation process of the first stiff column, and then fill the gap by secondary pouring. Although this construction method guarantees the stability and reliability of the structure to some extent, it has quite obvious drawbacks from the perspective of engineering progress. Because sufficient time must be reserved for the strength growth of concrete, the entire construction period is greatly lengthened. In some large-scale building projects with tight schedules and heavy tasks, the long waiting process not only easily leads to the delay of subsequent series of processes, increases the idle cost of manpower and equipment, but also may face the risk of default due to the lag of the overall construction period, bringing many obstacles to the smooth progress of the project.
