Reference numeral 1 denotes a terrazzo block mold, and the lower support member 2a of the terrazzo block mold 1 is installed in parallel with a constant distance therebetween, and is formed on the upper surface of the lower support member 2a. A plurality of angle members (3) formed in cross-section "b" shape are welded, and each of the angle members (3) has adjacent ends having both ends formed in "b" shape supported on the upper surface of the lower support member (2a). The welded and fixedly installed in contact with each other, each of the angle members (3) constitutes the bottom of the mountain-shaped uneven surface.

One side (right side in the drawing) of each of the angle members 3 installed as described above has a suitable thickness and one flat bottom member 31 is installed, and the bottom member 31 is a metal material and each of the angle members 3 is provided. It is welded to, or bolted together and fixed in riveted construction.

Both side wall plate members 4 having a suitable height are fixedly fixed at both ends of the plurality of angle members 3 fixed to the lower support member 2a.

One side upper end of the angle member 3 installed at the rear end of the angle member (right end in the drawing) of the angle members is in close contact with the upper end of the bottom member 31 on the opposite side where the bottom member 31 is not installed. The fixed plate member 5a is installed to be inclined to form a flat surface with the inclined surface 32, and both ends of the fixed plate member 5a are fixed to the inner surfaces of both side wall plate members 4 by welding.

In addition, the movable plate member 5b is detachably installed one by one at the upper end portion of each angle member 3 in front of the angle member 3 at the rearmost end at which the fixing plate member 5a is installed. Each of the movable plate members 5b is installed so that the fixed plate member 5a has the same inclination angle, and each of the movable plate members 5b has an inclined surface 32 in a state where the lower end thereof is in close contact with the upper end of the bottom member 31. ) Is installed to form a flat surface.

A length adjusting member 5c is inserted into both sides of each of the forming spaces 6 formed between the fixed plate member 5a and the plurality of movable plate members 5b, and the length adjusting member 5c is formed in the forming space. It acts to support the movable plate members 5b in the inserted state (6), and also selects and inserts a wider and narrower left and right width, and the left side of the terrazzo block (T) formed in the molding space (6). , Right is responsible for adjusting the length.

The length adjusting member 5c is made of a material such as rubber rubber, which is not bonded to artificial marble mortar.

When the fixed plate 5a and the movable plate 5b are installed at a sharp inclination angle, the front and rear widths of the terrazzo block frame can be narrowed, while the terrazzo block is installed at a gentle inclination angle. Although the upper and lower heights of the mold can be lowered, when the fixed plate and the movable plate are installed at a sharp inclination angle, the crushed stone of artificial stone mortar appears to be downward. The problem is that the angle of inclination of the fixed plate and the movable plate is so that when the artificial mortar is placed in each molding space 6, the artificial stone mortar is evenly filled in the molding space and the crushed stone is not driven to one side (lower side). It is a preferred configuration to install so as to have an angle (preferably in the range of 30 to 50 degrees) that can maintain an even distribution.

The pressing member 7 is installed in the front of the movable member at the front of each of the movable members 5b so as to be rotatable as a hinged structure to the lower supporting member 2a, and the pressing member 7 When forming the terrazzo block (T) to press the movable member (5b) at the very front, each movable member (5b) can withstand the placing pressure of the artificial stone mortar.
