AI Technical Summary
In existing technologies, scaffolding needs to be erected and dismantled during the construction of pre-reserved openings in floor slabs, which increases construction costs. In addition, traditional wooden formwork scaffolding systems occupy space and affect construction progress.
The non-removable mechanism, composed of steel plates, screws, angle steel, steel sheets, and square tubes, achieves stable installation of steel plates on the concrete floor slab surface through threaded connections and magnetic attraction. It is retained as a permanent structure, enhancing the tightness of the new concrete slab in the opening area and the load-bearing capacity of the surrounding floor slab, and avoiding the need for scaffolding erection and dismantling.
It reduces construction costs, improves the load-bearing capacity and integrity of the floor slab, simplifies the construction process, saves materials, does not occupy the space below the opening, and improves construction efficiency.
