Description
Technical Field
[0001] The utility model relates to the field of precast concrete block processing, in particular to a precast concrete block rotary body forming machine. Background Art
[0002] Precast concrete components are concrete building elements prefabricated in a factory or specialized production site. After a certain period of curing, they are transported to the construction site for installation. These components are widely used in modern construction and infrastructure projects. Precast concrete components offer several advantages: Factory production allows for better control of concrete mix proportions and construction processes, improving product quality; precast components can be produced concurrently with on-site construction, shortening the construction cycle; and factory production is relatively safe, reducing safety hazards associated with on-site construction. Precast concrete components are widely used in various construction projects, including residential and commercial buildings, industrial plants, bridges, tunnels, and roads. With advancements in construction technology, the design and application of precast concrete components are also evolving, with the introduction of more and more innovative materials and technologies, improving their performance and flexibility.

[0027] In the embodiment, a suitable forming mold is selected according to the shape and size of the cylindrical concrete component to be formed; after the forming mold is selected, the position height of the support base 2 is appropriately adjusted, and the rotating shaft at the bottom end of the forming mold is passed through the limit guide column 21 of the support base 2.
