FIELD
The present disclosure relates generally to the field of flooring. Specifically, various embodiments of the assemblies disclosed herein relate to a unique tapered floor and drain assembly.
BACKGROUND
Prior art modular building structures, specifically modular bathrooms such as that described in U.S. Pat. No. 8,596,021 to Van Ravenhorst, which is hereby incorporated by reference in its entirety, provide a flooring system referred to as the “Unifloor” system, and which is described as a composite construction (laminated fiberglass reinforced plastic) floor which can embody a simulated tile pattern, serves as the finished floor of the bathroom. In upscale environments such as high end commercial buildings and hotels, simulated finishes are not desirable.
U.S. Pat. No. 5,742,956 Tarver, which is hereby incorporated by reference in its entirety, teaches a modular bathroom unit floor fabricated of, for example, foam core material such as plywood sides having polystyrene foam or the like juxtaposed there between. Besides the well-known limitations of plywood as a moisture barrier, the moisture retention properties of plywood and resulting mold or mildew issues that can occur make plywood a less than desirable choice for flooring solutions in an environment that may be exposed to water. The use of plywood also results in increased weight to the bathroom module unit which increases shipping cost of the units.
SUMMARY
In view of the limitations now present in the prior art systems for flooring and drain system, embodiments described herein provide a novel tapered floor and drain assembly which is more efficient to manufacture, more systematic and organized for installation and more versatile in application and operation than known prior art systems. In certain embodiments, a modular system is provided wherein a drain assembly comprises multiple components and/or flooring members.
An object of certain embodiments of the disclosed system is to provide a new tapered floor and drain assembly for use within a modular building structure that will increase efficiency during the manufacturing, assembly, and installation processes. It is also a purpose of the disclosure to provide a new tapered floor and drain assembly that has many novel features not offered by the prior art, such as lightweight honeycomb flooring lower sub-panels and bisected honeycomb upper subpanels that allow for precision tapering of the floor towards the drain component as well superior structural support while reducing the overall weight of the floor. These are a few of the novel features that result in a new and unique tapered floor and drain assembly which is not apparent, obvious, or suggested, either directly or indirectly by any of the prior art device apparatus, or methods.
In various embodiments, subfloor panel members are provided that may be selectively customized. For example, in certain embodiments, at least one of an upper subfloor panel and a lower subfloor panel as shown and described herein comprises a honeycomb panel wherein the panel may be shaved, cut, molded, shaped, and/or compressed to provided a desired slope to the panel. For example, a honeycomb panel may extend substantially horizontally as a flat flooring surface along a portion of its area, while being shaped, angled, or tapered toward a drain feature surrounded by the panel(s).
There is a need for a bathroom unit flooring solution that is not only lightweight and structurally durable, and further allows for authentic finishes such as marble, granite, tile, stone, epoxy, composite or vinyl to be installed over the subfloor. Embodiments of the disclosure provide such a solution. The properties of the honeycomb material provide superb strength and structural support in the sub floor materials. The honeycomb material also allows the bisected honeycomb upper subfloor to be easily fabricated with a controlled, designed, tapered slope towards the drain unit to ensure that liquids will be gravity fed to the drain unit.
In various embodiments, lower and upper subfloor panels can be machine fabricated to provide increased accuracy and precision of fit as well as efficient modular production. The adhesives used are intended to be industry accepted materials for adhering and securing the component materials in position. The use of a water proof membrane in certain embodiments ensures that any water introduced into the environment will be collected and guided to the drain unit without causing damage to the main floor system components.
In one embodiment, a drain assembly is provided for a gravity fed floor drain, the assembly comprising a subfloor panel, a drain member comprising a drain outlet extending downwardly into the subfloor panel, and a flange extending laterally away from the drain outlet over at least a portion of the subfloor panel. An adhesive layer is provided to secure an underside of the flange to the subfloor panel. A flooring surface is provided, the flooring surface comprising a material that is substantially non-permeable to liquids, the flooring surface extending outwardly away from the drain member, and wherein the flooring surface comprises a first slope and a second slope. The first slope is provided at a location distal to the drain member, and the second slope is provided at a location vertically above and/or within an area defined by the flange, and the second slope is greater than the first slope to promote drainage into the drain member.
It is anticipated that the honeycomb subfloor panels can be fabricated as a single piece floor unit or as an assemblage of smaller section that when combined create a complete floor unit.
In certain embodiments, drain bodies of the present disclosure comprises circular drain members. Such circular drain members may be rotated even when in provided in a recess or cutout of the subfloor panel or other flooring components, thereby facilitating insertion and/or threading of a drain body with additional plumbing fixtures or features.
In certain embodiments, the present disclosure provides for methods for constructing a floor drain assembly. In one embodiment, a method for constructing a floor drain assembly is provided, the method comprising the steps of providing a first subfloor panel to a slab or foundation, the foundation comprising a void or aperture for plumbing. A second subfloor panel is provided and adhered to the first subfloor panel. A drain module is provided, the drain module at least partially extending into the void or aperture of the foundation. A primary flooring layer is provided on top of the second subfloor panel, and wherein the primary flooring layer extends over at least a portion of the drain module. In certain embodiments, the primary flooring layer is compressed or secured between a portion of the drain module and a drain cover. The drain cover may be secured to the drain module by one or more fasteners. In certain embodiments, the first and/or second subfloor panel is tapered, shaped, contoured, and/or compressed such that a portion of the panel(s) located generally distal to the drain module comprises a flat portion and wherein a portion of the panel(s) located proximal the drain module comprises a slope or taper to facilitate drainage of liquid from the flooring member(s) to the drain module.
It is further contemplated that the entire completed floor assembly can be installed as a single flooring unit or the floor assembly can be installed one layer at a time to thereby create the completed floor while still performing the intended purpose and function of the disclosure.
