Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a reinforcing device for anti-slope concrete formwork of balconies and bathrooms. Background Art

[0002] The specification requires that bathrooms and balconies be equipped with plain concrete counter-edges no less than 200mm high from the finished surface in accordance with waterproofing requirements. Depending on the requirements of different projects, the height of the counter-edge is generally between 250mm and 400mm.

[0003] 1. The existing anti-cantilever formwork includes wooden formwork and aluminum formwork. When wooden formwork is used for anti-cantilever formwork, the anti-cantilever reinforcement method is to use wooden squares to form a U shape and make holes in the vertical square wood, reinforce with screws, and support concrete strips inside the formwork. When pouring concrete, the wooden squares are prone to fracture and deformation at the perforated positions, and the horizontal square wood that serves as the upper connection is prone to loosening, causing the lower mold to expand. When aluminum formwork is used for anti-cantilever formwork, the anti-cantilever reinforcement is set with angle aluminum on the upper part of the aluminum formwork to ensure effective connection of the upper part of the aluminum formwork. The lower part of the aluminum formwork has no support and relies entirely on the strength of the aluminum formwork itself, which often causes the lower part of the anti-cantilever to expand.

[0004] 2. After the reinforcement of the anti-ridge formwork is completed, when pouring concrete, due to lateral pressure, it cannot be completely matched with the masonry structure. During the construction process, it is generally adopted to first drill holes on the concrete slab that has been poured, and then insert steel bars into the holes to fix the formwork so that it does not move. Although the process is simple, the method is rough and can easily cause water seepage on the main structure slab. The reinforcing steel bars need to be removed later, which not only poses a safety and quality risk, but is also time-consuming and laborious. Utility Model Content

The technical solution is that it includes two groups of symmetrically arranged vertical poles, connecting rods, and bolts. The two groups of vertical poles can move relative to each other through the connecting rods. The upper part of the vertical poles is connected with a support assembly, and the support assembly includes a support inner rod, a support outer tube, and a connecting piece. The vertical pole is connected to the support inner rod through the connecting piece, and the support inner rod is sleeved with the support outer tube.

[0006] Preferably, the vertical pole is made of square steel, a plurality of through holes are provided on the upper portion of the vertical pole, and a triangular steel frame is welded to the bottom of the vertical pole.
