AI Technical Summary
Technical Problem
The internal struts of a single row of steel bars in a cast-in-place concrete vertical slab cannot be stably fixed, leading to the risk of water seepage in the vertical slab and making subsequent construction complex and costly.
Method used
The system employs a combined internal strut mechanism, consisting of a main strut, an adjustable conical block, and a retaining ring. The retaining ring is engaged with a single row of steel bars to achieve stable support, and the system is sealed after dismantling to prevent water seepage.
Benefits of technology
This achieved stable positioning of the internal struts, ensured consistent thickness of the vertical plate cross-section, improved water resistance, simplified the construction process, and reduced costs.

Abstract
This invention discloses a method for supporting internal struts in concrete pouring formwork for single-row reinforced vertical slabs, solving the problem of how to stably and reliably position the internal struts and eliminate the risk of water seepage in the vertical slabs. A combined internal strut mechanism is constructed, consisting of a main strut and adjustable conical blocks at both ends. The three components are connected and supported between two vertical formwork panels, providing stable support. A cross-shaped reinforcing wing plate is provided on the main strut, and a vertical reinforcing bar connecting movable block and a horizontal reinforcing bar connecting movable block are respectively embedded between adjacent wing plates. A vertical retaining ring seat is screwed onto the vertical reinforcing bar connecting movable block, and a vertically rotatable retaining ring is movably connected to the vertical retaining bar in the single row of reinforcing bars. This achieves stable fixing of the main strut to the single row of reinforcing bars. The positioning of the internal strut between the two vertical formwork panels is achieved by the compression and positioning of the combined internal strut.
