Description

Technical Field

[0001] This invention relates to the field of construction technology for the main structure of building engineering, and in particular to a detachable and reusable two-section steel structure formwork reinforcement device and method for the lowered slab area. Background Technology

[0002] A suspended formwork reinforcement device is a reinforcement device used to strengthen suspended formwork. With the development of the construction industry, the application of steel structure buildings is becoming increasingly common. In structural construction, suspended formwork construction in the lowered slab area is unavoidable. Conventional devices use tie rods to fix the formwork to the reinforcing bars during suspended formwork construction in the lowered slab area.

[0003] 1. A Chinese patent discloses a formwork reinforcement device for the lowered section of a floor slab structure (Publication No.: CN217353535U), comprising a base rod, a first support rod, and a second support rod. The base rod is located in a horizontal plane, and the first support rod is vertically connected to the base rod. The second support rod includes an inclined section, a horizontal section, and a vertical section, all located in the same plane. The vertical section and the inclined section are located on the upper and lower sides of the horizontal section, respectively. The first support rod is positioned at the connection point between the inclined section and the horizontal section, with its top extending above the horizontal section. The portion of the first support rod extending above the horizontal section, together with the horizontal and vertical sections, forms a template placement groove for placing the formwork. The width of the template placement groove is adjustable. This formwork reinforcement device for the lowered section of a floor slab structure provides stable structure and solid support for the formwork, effectively improving the forming quality of the misaligned section. Furthermore, the adjustable width of the template placement groove allows for a wider range of applicable template thicknesses, enhancing its applicability.

[0004] 2. A formwork reinforcement device for cast-in-place strips of precast composite floor slabs (Publication No.: CN214785938U), comprising a composite slab and an aluminum alloy formwork, further comprising transverse reinforcing bars, formwork tie plates, pins, and pin plates. The formwork tie plates have notches on both sides, with a connecting section above the notch and a supporting section below. The top of the connecting section is fixedly connected to the middle of the transverse reinforcing bars, and pin holes are provided on the supporting section. The composite slab comprises a first composite slab and a second composite slab. The transverse reinforcing bars and the connecting section are located between the first and second composite slabs. The aluminum alloy formwork is located on the outside of the second composite slab and fixed to the formwork tie plates by means of pins and pin plates. The structure is reasonably laid out, easy to install and dismantle, has high overall structural strength, is conducive to improving construction quality, has good forming effect, and can prevent misalignment and grout leakage, making it highly practical.

[0005] Existing suspended formwork reinforcement devices require the tie rods to remain in the concrete for waterproofing, making the tie rods unusable. Furthermore, they are prone to bulging and formwork misalignment during concrete pouring and vibration. In steel structures, where steel is the main structural material, conventional suspended formwork devices are not well-suited for steel structures.

[0055] Beneficial effects of this invention;

[0056] (1) Rotating the nut can remove the mountain-shaped clamp, rotating the outer rod can separate the outer rod from the conical nut, and pulling the outer rod can remove the outer rod from the concrete formwork. The outer rod and the mountain-shaped clamp can be recycled for reuse, thus saving material costs. The four corners of the right side of the mountain-shaped clamp are set with an arc-shaped structure, which can improve the reinforcement effect.
