Abstract
Description
- This U.S. Non-Provisional patent application is a Continuation of and claims the benefit of priority from U.S. patent application Ser. No. 15/236,162, filed Aug. 12, 2016, now U.S. Pat. No. 10,183,462, which claims the benefit of priority from U.S. Provisional Patent Application Ser. No. 62/205,101, filed Aug. 14, 2015, the entire disclosures of which are incorporated by reference herein.
- The present disclosure relates generally to modular building units and structures. More specifically, the present disclosure relates to a pre-fabricated ceiling assembly with a plurality of layered materials or components, and methods of forming the same.
- Known ceiling structures for modular building unit structures comprise highly labor-intensive structures and associated methods of forming. Typically, prior art systems comprise cutting or shaping a ceiling panel from multiple pieces of fiber rock or sheet rock. The panel or panels are typically formed by computer-numerical-control systems and devices, but may also be machined or formed by hand or more conventional methods. Steel studs and reinforcing structures are cut and formed to fit a particular ceiling panel, and a stud frame is assembled for each particular ceiling. A jig table is typically used for such assembly processes. The cut fiber rock is then formed into place on the stud frame by known securing methods including fasteners and adhesives. It is also known to provide the assembled ceiling panel on a vertical finishing table and employ a multi-step process to finish the panel to a level five finish, which is desirable or required for areas and rooms where lighting is an important consideration. As used herein, “level five” finishes include, for example, those described in the Gypsum Association published standard GA-214-10.
- Prior art devices are generally labor intensive, expensive, and generally fail to provide a prefabricated ceiling structure that is adapted to and operable to be provided with a prefabricated building unit or structure. Further, these devices generally fail to disclose or provide enhanced safety features including, but not limited to flame retardant features.
- In view of the limitations present in modular ceiling assemblies, embodiments of the present disclosure provide novel pre-fabricated modular ceiling assemblies which are more efficient to manufacture, more systematic and organized for installation and more versatile in application and operation and more cost effective for mass manufacturing purposes, as shown and described herein.

FIG. 1 is a top perspective view of apre-fabricated ceiling assembly 2 comprising a main ceiling panel 4, at least oneelectrical conduit 6, at least one lighting orfan assembly 8, a plurality of reinforcingmembers 10, and related adhesives and installation fixtures and hardware. In certain embodiments, the main ceiling panel 4 comprises a mono-formed composite ceiling with a prefinished texture including, for example, a polyester surface veil impregnated with unsaturated resin solution. - In various embodiments, a main ceiling panel is provided and comprises a plurality of layers. In one embodiment, the layers comprise a fiberglass or woven glass layer, such as an 1808 woven roving glass layer; a fire-retardant layer, such as an ASTM E84 polypropylene tripolymer honeycomb layer; an additional glass layer, such as an 1808 woven virgin glass layer; and a surface layer, such as a veil for aesthetic and/or acoustic purposes.
- As shown in
FIG. 1 , the main ceiling panel 4 comprises a plurality of reinforcingmembers 10, such as steel studs, to provide structural support to the panel 4 and related components and accessories. The number and type of reinforcingmembers 10 may be varied based on the size, shape, thickness, structure, etc. of an associated ceiling panel 4. The ceiling panel 4 is preferably shaped, cut, or sized to fit aprefabricated building unit 12. Theprefabricated building unit 12 may comprise any number and type of building units including, but not limited to, modular prefabricated bathroom units. -
FIG. 2 is a partially exploded perspective view of apre-fabricated ceiling assembly 2 comprising a main ceiling panel 4. As shown, the main ceiling panel 4 comprises a plurality of pre-formed cut-outs orapertures 14 to accommodate lighting and ducting features, for example. -
FIG. 3 is an exploded, cross-sectional elevation view of components or layers for forming a ceiling structure according to one embodiment of the present disclosure. As shown, a ceiling panel or portion of a ceiling panel in accordance with one embodiment of the present disclosure comprises afirst finishing mat 20 a as a lower or base layer of the panel or structure. A firststructural fiberglass mat 22 a is provided above thefirst finishing mat 20 a. A fireresistant layer 24 is provided as an interior layer, the fire resistant layer preferably comprising a honey-comb core layer with at least some fire resistant properties or treatment. The fireresistant layer 24 is provided between the firststructural fiberglass mat 22 a and a secondstructural fiberglass mat 22 b. As shown, a fireresistant veil 26 is provided vertically above the secondstructural fiberglass mat 22 b. Asecond finishing mat 20 b is provided as an upper layer of the ceiling panel. - In various embodiments, including but not limited to the embodiment provided in
FIG. 3 , the layers are preferably laminated, joined or formed using a linear pultrusion impregnation system with unsaturated polyester resin solution at a temperature range of approximately 250-500 degrees Fahrenheit, and preferably approximately 325 degrees Fahrenheit. The pultrusion process of the present disclosure comprises a process wherein at least some of the layers provided inFIG. 3 , for example, are bonded under heat and pressure. U.S. Patent Application Publication No. 2001/0048175 to Edwards et al., which is hereby incorporated by reference in its entirety, discloses a process for in-line forming of pultrusion composites. Processes and features of Edwards et al. may be employed in embodiments of the present disclosure. The present disclosure contemplated methods of forming a ceiling panel using pultrusion processes as opposed to convention wet molding of layers. U.S. Pat. No. 8,182,643 to Fanucci et al., which is hereby incorporated by reference in its entirety, provides a process for fabricating structure including a pultrusion process. Such features and methods are contemplated for use in combination with embodiments of the present disclosure. Pultrusion processes contemplated for use in forming ceiling structures according to various embodiments of the present disclosure have provided unforeseen and novel advantages over known construction and formation methods. For example, the use of an in-line pultrusion process in forming ceiling structures of the present disclosure have been shown to reduce or avoid the occurrence of swelling or bulging of the ceiling structure during and after formation. The application of heat and pressure to the various layers shown and described herein provides distinct advantages over known devices and methods. In certain embodiments, the bonding process is accomplished with the addition of a fire-resistant resin and finishing the product with a fire-resistant bonding coat.
