The prefabricated wall panel includes a first concrete block, a second concrete block, and an insulation panel sandwiched between the two concrete blocks. A plurality of spaced-apart hollow tubes extend between the top side and the bottom side of the prefabricated wall panel and each tube has a flange at its a periphery. The tubes reinforce the first concrete block, and the flanges are supported on the top side of the wall. The horizontal beam is fastened to these flanges. The prefabricated wall panel further includes a U-shape beam that extends from the top side to the bottom side and is positioned at or near the left side or the right side of the prefabricated wall panel. A plurality of slings spaced apart run along a length of the U-shape beam and can provide for assembling two wall panels.
