Claims

[Scope of utility model registration request]

A plurality of oval-shaped depression-bottomed platform-like projections 2 are provided vertically in parallel on the inner surface of the front panel 1, and U-shaped anchor reinforcing bars 3 are installed above the upper end and below the lower end of the platform-shaped projections.
The legs 4 are embedded and attached to the front plate 1 so that they are vertical, and the back plate 5 is formed to have the same shape and size as the front plate 1, and is fitted to the left and right sides of the upper and lower surfaces of the front plate 1.
A protrusion 6 and a recess 7 are provided, and an oval trapezoidal protrusion 8 and a U-shaped anchor reinforcing bar 9 are provided on the inner surface of the back plate 5 in the same shape and shape as the oval-shaped bottom trapezoidal protrusion 2 and U-shaped anchor reinforcing bar 3 on the front plate. A front plate 1 and a back plate 5 made of concrete blocks, which are formed to be large in size and facing each other, and are provided with receiving protrusions 10 on the left and right sides of the upper inner surface of the back plate 5 so that the upper surface thereof is flush with the upper surface of the back plate.
Rings 12 are formed at the four corners of the U-shaped portions of the U-shaped anchor reinforcing bars 3 and 9 provided on the inner surface of the U-shaped anchor reinforcing bars 3 and 9, and the four corner rings 12 of the cross-shaped reinforcing bars 11 welded at the intersections of the reinforcing bars are overlapped, and bolts 13 are attached to both. This relates to a prefabricated concrete block formed by inserting and tightening the front plate and back plate with cross-shaped reinforcing bars.
