Description

Technical Field

[0001] The invention belongs to the technical field of slope protection frame moulds, and in particular relates to a slope protection arch frame prefabricated component mould and a use method thereof. Background Art

[0002] Slope protection refers to the general term for various paving and planting on the slope surface to prevent the slope from being eroded. Slope protection arch frame prefabricated parts are commonly used skeleton structure components for slope protection. A large number of skeleton prefabricated parts are spliced ​​in an orderly manner to form a complete slope protection skeleton. Slope protection arch frame prefabricated parts are made by pouring and shaping concrete using special molds.

[0003] The utility model patent with application number 2024226360943 discloses a slope protection arch frame prefabricated component and its mold. The prefabricated component is in a 'Y' shape as a whole. When in use, the prefabricated components can be assembled horizontally to form a complete arch, and can be assembled vertically to form a multi-layer arch. Compared with the complete arch prefabricated components, it is easy to transport and not easy to damage. The mold includes a base plate, and the base plate is in a 'Y' shape. The base plate includes a longitudinal section and two arc sections. The two arc sections are bent to the left and right sides respectively and are both in the shape of a quarter circle. The tangent at the lower end of the arc section is vertical, and the tangent at the upper end is horizontal. A transverse section is formed between the inner ends of the outer edges of the two arc sections. The inner wall of the horizontal plate two is fixedly connected to the protrusion three, and the inner wall of the horizontal plate one forms a groove three outward, and the protrusion three corresponds to the groove three. The lower half of the end plate one is concave inward, and the lower half of the end plate two is convex outward.

[0004] Since the overlapping surfaces of the left and right ends and the upper and lower ends of the prefabricated part need to form a splicing mechanism, the inner wall of the end plate at the corresponding position of the mold is not a vertical plane. When the mold proposed in the above scheme is demolded, it is necessary to remove the bolts of each end plate and manually remove the end plate outwards, and then remove the remaining side panels to take out the product.

There is a uniform distance between the edge of the lifting plate 11 and the edge of the inner bottom of the casting cavity. The bottom of the bottom plate 1 is a base 12, and a control cavity is arranged inside the base 12. A lifting driving mechanism is arranged inside the control cavity.
