BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a mold making technique, and more particularly, to a mold making method for quickly and cost-effectively manufacturing a beam formwork.
Formwork is sometimes called a formwork as a temporary structure that cures unreinforced concrete to cure concrete structures to a certain shape or size and cures and supports them until strength is reached. Particularly, in the whole area of the building, beams are formed to reinforce the supporting force, and a mold capable of casting concrete is installed to form beams.
The formwork is manufactured using materials such as plywood or rigid fiberboard, synthetic resin, aluminum panel, steel plate, etc., and forms such as euro form, sliding form, vertical form form, table form form, tunnel form form, waffle form, have. In recent years, various methods have been developed to secure sufficient strength to formwork and to secure work with less manpower.
Generally, the form is composed of a side panel panel welded to both sides of a support panel and a support panel. However, in the related art, the size of the support panel and the side panel panel are different shall.
As a result, when a mold is manufactured according to the prior art, it takes a lot of time to manufacture and it can not cope with the amount of customized products.

The prior art is not suitable for a mass production system because the shape of a mold to be molded is complicated and diverse and the cost of the molding equipment is excessively increased and the time required for changing the roll of the molding machine is considerably required.
However, according to the present invention, it is possible to manufacture the formwork of a desired size at an economical cost and time by standardizing the form of the formwork and fabricating the formwork side plate and the bottom plate by appropriately combining basic basic units. Especially, the molding equipment cost can be saved by standardizing the bottom plate with the same standard as the side plate.
The perpendicular bending portion inside the lower part applied in the present invention is advantageous in that rigidity in the longitudinal direction is strengthened, deformation due to external impact at the time of transportation and installation is prevented, and the concrete is poured and the bending force is exerted during the axial load after the installation .
