Description
Technical Field
The invention relates to a method for manufacturing a concrete precast slab, in particular to a method for manufacturing a cobblestone concrete embossed decorative precast slab; belongs to a method for processing a concrete prefabricated member.
Background
Cobblestones are a pure natural stone material, which has been widely used in parquet pavements in parks, courtyards, scenic spots, etc.; it is popular with people because of its simple and elegant oriental style.
At present, the manufacturing process of a cobblestone pavement is generally as follows: firstly concrete mortar is paved on the road surface, then cobblestones are embedded into the mortar one by one according to a pre-designed scheme, and the cobblestone road surface is finished after the mixed collar soil is solidified. The method has the defects of long site construction period, high labor intensity and construction difficulty, high technical requirement on cobble pattern arrangement, incapability of realizing large-scale industrial production and the like. In addition, due to the adoption of manual operation, the embedding depth is difficult to control, the leveling effect of the pattern surface is influenced, the phenomenon of loosening and falling is easy to occur, and the quality is difficult to ensure. The wall pattern made of cobblestones has the defects of high construction difficulty, easy falling of cobblestones and the like.
For this reason, patent document "CN 107662280A" discloses a "production process of a novel cobble preform". The technical scheme is that patterns are drawn or etched on a mold in advance, and cobblestones with different colors and sizes are closely arranged and paved on the bottom of the mold according to the pattern requirements of the bottom of the mold by a mold pattern worker; filling the mould with concrete slurry or colloid, turning over the mould, removing the concrete slurry or colloid from the surface of the prefabricated cobble part to expose one-half to one-eighth of the cobble, drying and solidifying the prefabricated cobble part, taking out, packing and packing. The method has the following defects:
1) because the patterns are drawn or etched, cobblestones paved at the bottom of the mold are easy to move and dislocate due to the extrusion of concrete mortar during pouring and mixing, so that the parquet patterns are changed;
2) the manual picture arrangement efficiency is low and the labor intensity is high;
3) the pattern is easy to be blurred due to abrasion, and meanwhile, the pattern is easy to be polluted by concrete, so that the pattern is required to be cleaned, and labor and time are wasted;
4) the brick has the defects of weak strength, easy breakage and the like because no reinforcing rib is arranged.
Disclosure of Invention
Aiming at the defects in the prior art, the invention aims to provide the manufacturing method of the cobblestone precast slab, which has the characteristics of high production efficiency, low labor intensity, good pattern matching effect, good product strength, difficulty in falling of cobblestones and the like.
In order to achieve the purpose, the invention adopts the following technical scheme, and the specific steps are as follows:
1) arranging a latticed positioning frame in a die cavity of a die, and ensuring that the bottom end of the positioning frame is 1-2 cm away from the bottom surface of the die cavity;
2) placing the mould on a vibration frame, and then putting cobbles with basically the same size and shape;
3) starting the vibration frame until the cobblestones fall into all the positioning grids on the positioning frame;
4) picking up redundant cobbles;
5) placing a latticed reinforcing rib net with the same shape and size as the positioning frame on the cobblestones, and ensuring that more than 70% of the cobblestones fall into positioning meshes of the reinforcing rib net;
6) injecting concrete into the mould, and vibrating and compacting;
7) turning the die by 180 degrees and demoulding;
8) and removing the concrete on the surface of the product before the concrete is solidified until the cobblestones are exposed.
In the technical scheme, a plurality of positioning grids on the positioning frame form a preset pattern, adjacent positioning grids are fixedly connected through reinforcing ribs, the size and the shape of each positioning grid are the same, and the width of each positioning grid is slightly larger than the thickness of a cobblestone; the length of each positioning grid is slightly smaller than the width of the cobblestones, and the distance from the top surface of the positioning frame to the bottom surface of the concave cavity is larger than one half of the length of the cobblestones.
In the technical scheme, a plurality of positioning grids on the positioning frame form a preset pattern, adjacent positioning grids are fixedly connected through reinforcing ribs, the size and the shape of each positioning grid are the same, and the width of each positioning grid is slightly larger than the thickness of a cobblestone; the length of each positioning grid is smaller than the length of the cobblestones but larger than the width of the cobblestones, and the distance from the top surface of the positioning frame to the bottom surface of the concave cavity is larger than one half of the width of the cobblestones.
The further technical scheme of the invention is as follows: the positioning grid is rectangular, rhombic or elliptical.
Compared with the prior art, the invention adopts the technical scheme, and has the following advantages:
1) because the latticed positioning frame is adopted, the cobblestones can be quickly arranged vertically or laterally in a vibration mode, the production efficiency can be greatly improved, and the labor intensity can be reduced;
2) the latticed positioning frame can effectively restrain cobblestones and avoid the cobblestones from moving and dislocating under the action of external force (such as vibration and concrete extrusion impact);
3, the cobblestones are arranged vertically or laterally, so that the contact area between the cobblestones and concrete can be increased, the adhesive force of the cobblestones is improved, and the defect that the cobblestones are easy to loosen and fall off in the traditional method is effectively overcome;
4) the cobblestones are screened, so that the cobblestones have basically the same size; therefore, when the cobblestones are positioned upright or side-erected in the positioning grids of the positioning frame, the height and the size of the exposed parts of the cobblestones can be ensured to be basically consistent, and the smooth and attractive patterns can be ensured;
5) the latticed reinforcing rib net arranged in the grid is added, so that the strength of the product can be improved, the product can be prevented from being broken, the cobblestone can be limited, and the cobblestone can be prevented from loosening and falling off.
