[0028] Referring to FIG. 1 which shows a perspective view of a prefabricated wall panel 100 according to an exemplary embodiment of the present invention. The disclosed prefabricated wall panel 100 can be made from concrete and reinforced using metal mesh and thick steel rebars. FIG. 1 shows the prefabricated wall panel 100 has two concrete blocks, a front concrete block 110 and a rear concrete block 120, and an insulation layer 130 sandwiched between the two concrete blocks. A section of the prefabricated wall panel is shown without concrete to illustrate the different components within the front concrete block. The thickness of the two concrete blocks can be varied and usually, one concrete block can be thicker than the second concrete block. The thinner concrete side can face outside the building and one or more suitable coatings can be applied to the thinner concrete block, for example, a stone veneer can be applied on the outer surface of the thinner concrete block. The rear concrete block 120 in FIG. 1 is the thinner concrete block.

[0029] A rebar mesh 140 can be seen embedded throughout an area of the front concrete block 110, wherein the rebar mesh 140 can provide for reinforcing the structure. The rebar mesh 140 can include metal wires arranged in a grid-like fashion such that a square void is formed between the interlocking metal wires. In one implementation, a 4 mm steel wire can be used for the rebar mesh 140 with square voids throughout.

[0030] The strength of the structure can be further enhanced by rebar truss 150. The rebar truss 150 can be used to reinforce the wall panel and can be disposed around doors and windows and sides for added strength. The reinforcement of the concrete wall panels using the rebar mesh and rebar truss are known in the art and hence not further described herein. Also, the thickness of the two concrete blocks and the sandwiched insulation layer can be varied without departing from the scope of the present invention. In one implementation C30 concrete can be used for the two concrete blocks, the C30 concrete is known in the art. Also, disclosed is a method for reinforcing the insulation panel by using metal U-type connectors 160 for fastening the two concrete blocks and the insulation panel. The insulation panel can be extruded polystyrene insulation (XPS) panels commercially available, such as from OWENS CORNING®. It is understood, however, that any wall insulation panel known to a skilled person for use in precast wall panels can be used without departing from the scope of the present invention. The insulation panel, also known as an insulation board, can act as a sound barrier, heat barrier, and can also prevent moisture seeping into the walls from outside. Additionally, the exposed surface of the thinner concrete block that faces outside of the building can be treated with waterproof coatings.

[0031] FIG. 1 also shows a switch box 165 and an electrical functional box 170 built into the wall panel 100. The switch box and the electrical functional box can be supported by the rebar mesh or rebar truss, and then the concrete can be filled into the front concrete block. The switch box and the electrical functional box can be any standard electrical components known and approved for use in a residential and commercial building. The location of the switch box and the electrical functional box can be predetermined and accordingly positioned in the wall panel. The provision of the built-in switch box and the electrical functional box offers a great advantage preventing later cutting off the wall to make room for the switch and electrical boxes that is messy, laborious, time-consuming, and increase the overall construction cost. Suitable conduits and extruded holes 175 can also be provided in the front concrete block 110 for electrical wires and plumbing that has to travel through the wall. The switch and electrical boxes can have connected conduits that open at the top of the wall panel and can be used for passing the electrical wires. FIG. 1 shows a single switch and electrical box; however, it is understood that more than one switch and one electrical box can be provided without departing from the scope of the present invention. The unused extruded holes can be filled with concrete at the job site.

[0032] On the left side and the right side of the wall panel 100 can be seen a U-shape beam 180 that extends from top to bottom of the first concrete block 110. The U-shape beam 180 can be made from a planar sheet that can be folded twice at a spaced-apart distance to form a three-sided or substantially U-shape beam. The U-shape beam 180 can be provided at the ends or near the ends of the wall panel for interlocking one wall panel to another wall panel while assembling the wall panels at the job site. The position of the U-shape beam 180 in a wall panel can depend upon the position and angle at which the two wall panels must be coupled. Steel slings 185 can also be provided along a length of the U-shape beam 180 at regular intervals to reinforce a joint between the two adjacent wall panels. The slings 185 can be fastened to a base of the U-shape beam 180 and extends outwards and away from the wall panel and in between the two plates of the U-shaped beam 180. In use, the two wall panels that have to be assembled can be bought close to each other such that the slings 185 of the two wall panels are one above the other and the two U-shaped beam 180 of the two wall panels can form an enclosed volume. Thick rebar can be inserted which passes through the overlapping slings of the two wall panels. Once the rebar is through, concrete can then be poured into the enclosed volume to join the two wall panels. It is understood that the slings can be provided on other portions of the front concrete block, as shown in FIG. 1. The slings can be loop-shaped and fastened to the U-shape beam, the rebar, and/or rebar mesh. The loop-shaped slings can be replaced by U-shape brackets, and such U-shape brackets are within the scope of the present invention. Also, shown in FIG. 1 are the connectors for steel girders.

[0033] Also, it can be seen in FIG. 1 are the tubes 190 run top to bottom at regularly spaced intervals. The tubes 190 can be hollow and made from a durable material that can provide additional reinforcement to the prefabricated wall panel 100. In one implementation, the tubes can be made of steel with an outer diameter of about 40 mm and the two tubes in the prefabricated wall panel can be spaced about 900 mm from each other. On top of the tube can be seen a flange 195 extending perpendicular from a periphery of the tube. The flange can be welded to the periphery of the tube and can rest upon the top side of the wall panel. Additionally, the flange can be fastened into the concrete of the wall panel using suitable fasteners. The flange can also be made from a durable material, such as steel. These flanges can provide support for the horizontal beams that are mounted on the top of the wall panels.

[0034] The horizontal beams can be mounted on the top of the wall panels and run along the length of the wall panels. The horizontal beams can allow mounting a ceiling on the top of the assembled wall panels.

[0035] Referring to FIG. 2 which shows a prefabricate wall panel apparatus 205 having the prefabricated wall panel 200 and a horizontal beam 210 mounted on the top of the prefabricated wall panel 200. The horizontal beam 210 can include a top plate 220 and a bottom plate 230 those could be parallel to each other. The bottom plate of the horizontal beam can rest upon the top of the wall panel 200 and can be welded to the several flanges of the tubes disposed in the wall panel 200. Additionally, the steel plates can be used to join the horizontal beam to the wall panel or the two wall panels, wherein the steel plates can be of a rectangular shape, T-shape, or an L-shape.

[0036] The horizontal beam 210 can have several spaced apart bores 240 of a square shape therethrough between the top plate and the bottom plate. The space between the two adjacent bores of the horizontal beam can be equal to the space between the two adjacent tubes in the wall panel. In use, when the horizontal beam is mounted on the top of the wall panel such that the bottom plate of the horizontal beam rests upon the top of the wall panel, the horizontal beam can be positioned so that the bores of the horizontal beam can be coaxially aligned with the bores in the tubes of the wall panel. A ceiling panel can be mounted on the horizontal beams of the assembled wall panels, and the ceiling panel can also have bores through which rebars can be inserted, wherein the rebars can passthrough the bores of the horizontal beams into the tubes or extruded holes of the assembled wall panels. The bores in the horizontal beam can be square shape or cylindrical, FIG. 2 shows square shape bores.

[0037] Referring to FIG. 3 which shows the prefabricated wall panel 300 of the disclosed prefabricated wall panel apparatus as shown in FIG. 2 but without the horizontal beam. The disclosed prefabricated wall panel 300 may differ from the prefabricated wall panel 100 shown in FIG. 1 by omitting a few features such as the extruded holes, girders, and U-shape beam. In a preferred embodiment, the prefabricated wall panel 300 can include a rear concrete block 305, an insulation panel 310, and a front concrete panel 315, the structure and functioning of the three has been described for the prefabricated wall panel 100 and hence not repeated here. The disclosed prefabricated wall panel 300 can also include wire mesh bar 320 that has been previously described for the prefabricated wall panel 100. Wire mesh 325 can also be seen in FIG. 3 that is typically dense wire mesh and can be used around doors and windows for added strength. The prefabricated wall panel 300 can further include steel rebars 330 for reinforcement and structural support. Steel rebars of a diameter of about 12-16 mm can be used, and more preferably, of about 16 mm can be used such that a building can easily withstand hurricanes, earthquakes, and the like natural disasters. The prefabricated wall panel 300 can further include a U-shape or rectangular or square grooves 335 in the front concrete block for the water pipes to run up the wall. The prefabricated wall panel 300 can further include electrical switches 340 and electrical functional boxes 345 both have been described for the prefabricated wall panel 100 and hence not repeated here. Tubes 350 can also be seen in FIG. 3 that has been previously described for the prefabricated wall panel 100 in FIG. 1. The tubes 350 can be hollow and shown to be of square in shape. The steel tubes 350 can provide for additional reinforcement. Also, these tubes 350 can act as a support for mounting other elements, such as the horizontal beam. The flange 355 at a periphery of a square shape aperture can be welded to a periphery of the tube 350 and the flange can also include fasteners for anchoring to the concrete block, also described for the prefabricated wall panel 100 and not repeated here.

[0038] The prefabricated wall panel 300 can also include another U-shaped concrete molded U-beam 360 that can be stronger and better than using a metal U-shaped beam 180 in FIG. 1. The concrete molded U-beam can be molded at the time of manufacturing. A rigid double steel sling 365 can also be seen in FIG. 3 that extends from the U-shaped concrete molded U-beam 360. As described for the prefabricated wall panel 100, the U-shaped concrete molded U-beam 360 and the rigid double steel sling 365 can be used for joining two prefabricated wall panels, and the process is not repeated here. The rigid double steel sling 365 in comparison to the slings 185 shown in FIG. 1 can provide better strength and functionality. As shown in FIG. 3, a loop of the slings 360 can be wrapped around the tube 350 adjacent to the U-shaped concrete molded U-beam 360 and the end of the sling 365 can be further embedded into the concrete. A lifting point stiffer 370 can also be seen in FIG. 3 that can be used to lift the prefabricated wall panels 300 and floor foundations into place. Also shown in FIG. 3 is a C-type angle bracket 375 for horizontal section.
