Abstract:
Disclosed in the present invention are a combined accessory of a concrete mold-free-forming bearing component and a preparation method. The combined accessory is composed of concrete and a mesh mold, wherein the concrete is coarse-fine mixed aggregate concrete or unitary fine aggregate concrete, the unitary fine aggregate concrete being 3-D printing concrete; the coarse-fine mixed aggregate concrete has fine aggregate having a particle size of 0.08 mm to 4.75 mm and coarse aggregate having a particle size greater than or equal to 5 mm, and has a fluidity greater than or equal to 70 mm and less than or equal to 250 mm; the 3-D printing concrete has fine aggregate having a particle size of 0.08 mm to 4.75 mm, and has a fluidity greater than or equal to 110 mm and less than or equal to 190 mm; the mesh mold is a rib mesh or a steel plate mesh, with the diameter of ribs being greater than or equal to 0.5 mm, and the pore diameter of a mesh of the rib mesh is less than or equal to 7.5 times the maximum particle size of the fine aggregate, and is greater than or equal to 7.5 times the minimum particle size of the fine aggregate; and after first-layer concrete printing concrete is poured, the mesh mold is wrapped in the concrete and combined with the mesh mold into a whole, and after the concrete has solidified and hardened, a support can be formed, that is, subsequent multi-layer concrete consecutive pouring and stacking can be performed thereon.
