In order to study the parameters of the automatic tying equipment for steel skeletons of precast shear walls, 19 precast-shear-wall projects and 16,036 precast-shear walls have been explored, with the thickness of the steel skeletons being studied according to the specifications and sleeve diameters, and the difference between production with and without edge forms being analyzed. The study displays that the automatic tying equipment for steel skeletons should be able to produce wall panels with a height of 2.5–2.95 m and a width of 0.8–5.9 m; the equipment should be able to produce 6–25 types of reinforcement bars with a diameter of 6–25 mm; the minimum spacing between the steel skeletons produced by the equipment should be 5 mm; the equipment should be able to produce shear-wall skeletons with a thickness of 150–170 mm; in case that the equipment producing the steel skeletons with side forms is more problematic, they should be produced without such edge forms. |
