Description

Technical Field

[0001] The utility model belongs to the technical field of concrete forming equipment, and more specifically relates to a prefabricating device for special-shaped concrete blocks. Background Art

[0002] Concrete precast blocks are mainly used in auxiliary projects and are part of the highway construction process. In order to ensure the quality of the finished precast blocks, they are usually produced in a centralized precast yard and then transported to the construction site for installation.

[0003] For example, a Chinese patent with application number 2021208614435 discloses a special-shaped concrete precast block mold, which aims to solve the technical problems that existing plastic molds have different degrees of bulging, and are prone to collisions of edges and corners during demolding, resulting in poor appearance quality. The mold comprises a bottom mold, side molds respectively arranged on both sides of the bottom mold, and end molds respectively arranged at both ends of the bottom mold; the bottom mold matches the shape of the bottom surface of the special-shaped concrete precast block; the side mold comprises a side plate, a first angle steel respectively fixed around the side plate, and a second angle steel fixed at the upper and lower ends of the side plate, a bolt hole is provided on the first angle steel near one end of the side plate close to the end mold, and through holes are respectively provided on the second angle steel, the bottom mold is clamped between the two side plates, and the side plates on both sides of the bottom mold are fixed by tension bolts passed through the through holes; the end mold comprises an end plate, and the end plate is provided with bolt holes corresponding to the bolt holes at the left and right ends of the side mold, and the end plate is fixed to the side mold by bolts.
