Description

Technical Field [0001] The present invention relates to an angle mold apparatus for fixing a stone,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an angle mold apparatus for fixing a stone for cutting and bending an angle for stably fixing a building stone such as marble, granite, or artificial stone made of a plate having a predetermined thickness to a wall, To an angle mold apparatus for fixing a stone, which can produce standardized high quality angles while reducing the manufacturing time and manufacturing cost by simplifying the manufacturing process by automatically bending the bent angle through the bending mold.

Typically, buildings are finished with exterior finishes using a variety of finishes such as paint, tile, brick, metal or stone to make the exterior look beautiful. It is more aesthetic than the finishing materials of other materials. It can change the color saturation according to the degree of abrasion without having to undergo a separate coloring process. It is also possible to select the surface roughness and various expressions are possible. Stone finishes are widely popular.

As the stone finishing material, a stone wall board cut to a certain size and thickness of stone such as marble, granite and artificial stone is used. Such a stone wall board is made with a relatively high weight due to its material properties. Accordingly, a metal fixing stone for fixing the stone to the outer wall of the building is used. The angle of the stone fixing angle is formed by a structure bent approximately in the "b" or "d" shape to fix and support the heavy-weight stone wall plate stably to the outer wall of the building.

The angle of the stone fixing angle was manufactured by heating the bent portion of the angle at the site with a torch and then bending it by tapping with a hammer. However, since this method requires the operator to repeatedly perform the heating process and the bending process repeatedly, Manpower and time were consumed. In particular, it was virtually impossible to produce standardized high quality angles.
