Description

FIELD OF INVENTION

The present invention is related in general to a composite wall and, in particular, to a system, method and apparatus for providing a sound absorbing composite wall.

BACKGROUND OF THE INVENTION

There are a variety of modular and pre-fabricated wall designs which are increasingly popular in construction. Most commonly, these wall designs include lightweight panels which are stacked and connected to enclose a given space.

Current composite wall designs are limited to eight feet typically in an L/240 design. Additionally, current composite wall designs are required to be formed of plastic-based materials which are not aesthetically pleasing such as Polyvinyl Chloride (PVC), Polypropylene (PP) and the like. These plastic-based materials also have poor sound absorbing properties. For this reason, current composite wall designs have a limited appeal compared to traditional wood and brick wall designs.

What is needed is a light weight wall system which can be over eight feet in an L/240 design. Further, a composite wall system is needed which allows for improved aesthetic appeal. Further, a composite wall system is needed which has improved sound-absorbing qualities.

SUMMARY OF THE DISCLOSURE

The present invention overcomes the limitations of the prior art by providing a light weight, composite wall system. According to a preferred embodiment, the present invention includes a sound absorbing wall assembly system which includes a wall beam with detachably mounted wall panels. According to further aspects of the present invention, the wall beam preferably includes an upper surface, a lower surface and a back beam surface which is connected between the upper and lower surfaces. According to further aspects of the present invention, the upper surface of the wall beam includes a corrugated rib and an upper connecting flange, and the lower surface includes a lower corrugated rib and a lower connecting flange.

According to further aspects of the present invention, the detachable face panel of the present invention may include a front surface having grill openings, and a rear surface which includes upper clips and lower clips. Further, the present invention may further include insulation material which is enclosed between the wall beam and the face panel to absorb sound.

According to further aspects of the present invention, the face panel of the present invention may attach to the wall beam by inserting a lower clip of the face panel over the lower connecting flange and securing the upper clip over the upper connecting flange to create a frictional fit.

Other goals and advantages of the present invention will be further appreciated and understood when considered in conjunction with the following description and accompanying drawings. While the following description may contain specific details describing particular embodiments of the invention, this should not be construed as limitations to the scope of the invention but rather as an exemplification of preferable embodiments.

FIG. 1 shows a side, perspective view of a beam wall assembly 100 in accordance with a first preferred embodiment of the present invention. As shown, a beam wall assembly 100 may include an extended wall beam 102 with a detachable face panel 104. The beam wall assembly 100 preferably includes sound absorbing features as will be discussed further below. According to a preferred embodiment, the wall beam 102 may preferably be formed of fiberglass. Alternatively, the wall beam 102 may be formed of any other rigid, lightweight materials such as plastic, aluminum, or the like. As shown, the wall beam 102 is preferably hollow and formed as a shell to provide strength and stability to the beam wall assembly 100 to achieve an L/240 value at greater than 14 feet. The beam wall assembly 100 is preferably further designed so that the face panel 104 may be detachably mounted to the wall beam 102 as detailed below.

With reference now to FIGS. 2 and 3, an exemplary wall beam 102 in accordance with a first preferred embodiment of the present invention shall now be discussed. FIG. 2 provides a first perspective view of an exemplary wall beam 102 and FIG. 3 shows a side cutaway view of the same. As shown, the wall beam 102 is preferably formed as a length of beam having an upper surface 106, a back beam surface 116 and a lower surface 111. As shown, the upper surface 106 preferably includes at least one corrugated rib 108 and an upper connecting flange 110. The back beam surface 116 may be smooth or may include central ridges 118 to allow for flexibility and/or added strength within the wall beam 102. The lower surface 111 may preferably include corrugated ribs 112 and a lower connecting flange 114. As shown, the top corrugated rib 108 may preferably mate with the lower corrugated ribs 112 so that one wall beam assembly 100 may be stacked on another to form a larger wall as shown in FIGS. 9 and 10.

With reference now to FIG. 4, a front view of an exemplary face panel 104 in accordance with a preferred embodiment of the present invention shall now be discussed. As shown, the face panel 104 includes a front face 105 which preferably includes a plurality of grill openings 107 to assist with sound intake and sound absorption. According to preferred embodiments, the face panel 104 may formed of nylon plastic or the like. Alternatively, any material may be used to meet the aesthetic and weight requirements of a given installation. Importantly, the design on the front face 105 may be changed to show any given design. For example, the front face 105 may include a faux brick look which may be created by providing slotting on the front face 105 to resemble a brick face. Further, the grill openings 107 may be arranged to resemble grout lines or the like. Further, the amount of open space on the front face 105 may be changed as required. Preferably, the grill openings 107 and/or the entire front face may be covered in wired mesh or the like to prevent ingress of debris and flying insects. Any such mesh may be attached via ultrasonic welding or other process.

With reference now to FIG. 5, a rear surface 132 of the face panel 104 is shown. When attached to the wall beam 102, the rear surface 132 faces the wall beam 102 so that the rear surface 132 is enclosed within the beam assembly 100. As further shown, the face panel 104 further includes upper clips 124, 126 and lower clips 128, 130 for securing the face panel 104 to the wall beam 102 as discussed further below.

With reference now to FIG. 6, a side cutaway view of a fully assembled beam wall assembly 100 is shown. As shown, the face panel 104 is attached to the wall beam 102 preferably at two points. According to a preferred embodiment, the face panel 104 may be attached by inserting one or more lower clips 130 (clip 128 not shown) of the face panel 104 over the lower connecting flange 114 and then pressing the upper clips 126 (clip 124 not shown) against the upper connecting flange 110 so that the upper surface 106 bends and the upper clip 126 snaps over the upper connecting flange 110 to create a frictional/tension fit. As further shown in FIG. 6, the beam wall assembly 100 may preferably enclose foam insulation 122 or the like to aid noise reduction. According to a preferred embodiment, the foam insulation 122 may preferably be sufficient to provide a Noise Rating Coefficient (NRC) greater than 0.85 and a Sound Transmission Class (STC) above 30.

FIG. 7 shows a side cutaway view of the beam wall assembly 100 shown in FIG. 6 labelled with exemplary dimensions. As shown, the beam wall assembly 100 may preferably be approximately 12.5 inches in total height with 11 inches of the front face 105 visible.

FIG. 8 shows a perspective view of an extended beam wall assembly 100 in accordance with a further preferred embodiment of the present invention. As shown, a single wall beam 102 may be of any length and may attach to any number of face panels 104a-d as needed to extend horizontally. Further, each wall beam 102 may be stacked with other wall beams as shown in FIG. 9. As shown, groups of wall beam assemblies 100a-100d preferably interlock to form a wall of the desired height. FIG. 10 provides an example of a fully formed wall 134 which includes multiple, stacked wall assemblies and faux brick face panels.
