Description

Technical Field

[0001] The utility model relates to the technical field of casting imitation wood grain concrete piles, in particular to a tenon-under-type mould for casting imitation wood grain concrete piles in a single mould. Background Art

[0002] In the process of casting imitation wood grain concrete piles, molds are usually used for casting. In order to adapt to the installation and casting of the internal skeleton of the imitation wood grain concrete pile, the existing molds are usually designed with detachable side molds. The closing of the side molds is used to form the casting cavity and fix the internal skeleton. The disassembly of the side molds facilitates the demoulding of the imitation wood grain concrete pile after forming.

[0003] However, in the actual molding process, since the inner frame needs to be cast in the concrete pile, the inner frame needs to be fixed before pouring, and the existing fixing methods mostly fix the inner frame on one side, resulting in insufficient fixing stability and easily causing eccentric mold during concrete pouring.
