Description

Variable Mold Apparatus The present invention relates to a variable mold device capable of finely adjusting the length, width, and height to fit the specifications of a concrete member. In general, precast concrete, distinct from cast-in-place concrete, can be applied in concrete construction. Since precast concrete utilizes prefabricated concrete components manufactured in advance, it offers advantages such as shortened construction time, improved workmanship, and the ability to impart superior structural and functional performance through various treatments during the molding process. Such precast concrete can be utilized for a wide range of applications, including general structural materials, walls, interior and exterior finishes, pipe or foundation components, concrete railway sleepers, and railway facilities. Furthermore, precast concrete components are widely used in construction projects that require a large number of components of the same specifications. The aforementioned precast concrete members are manufactured in a mold apparatus. Mold apparatuses are generally constructed using materials such as steel plates to enable repeated reuse. In other words, traditional precast concrete is formed by welding mold members of fixed shapes and dimensions. Since such mold apparatuses have fixed shapes and structures, a separate new mold must be manufactured and used when changes to the shape or dimensions of the object to be molded are required. However, while the overall shape of the molded members does not vary significantly in most applications of precast concrete, there are often cases where multiple types of members are required in terms of detailed specifications, with foundation members for various plant structures being a prime example. Furthermore, despite most foundation members having a rectangular shape, different molds are typically applied due to minute differences in detailed specifications such as width, length, and height. Accordingly, there is a demand for technology that enables the precise adjustment of mold device specifications.
