Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and more specifically, to a rapid installation and dismantling operation platform for casting steel structure columns with good protection. Background Technology

[0002] Traditional steel pipe column core grouting employs a concrete jacking process, which involves significant investment of labor, materials, and machinery, resulting in complex and slow construction. With technological advancements and the application of scientific and technological achievements, a self-made steel structure operating platform combined with a vibration-free, self-compacting concrete core grouting process has been adopted. This saves labor days spent sealing grouting holes, and the steel plates used for sealing the grouting holes no longer require a tower crane for core grouting, significantly accelerating construction progress and shortening the construction period. Many existing steel pipe concrete column pouring platforms are fixed installations, leading to significant time commitments during initial installation and subsequent dismantling, thus impacting the pouring schedule and overall project progress. Therefore, a highly protective, rapid installation and dismantling operation platform for steel pipe concrete column pouring is needed. Utility Model Content
