Description

BACKGROUND

1. Field of Embodiments

The disclosed embodiments relate to an insulated floor system for wet and high humidity space, and more specifically to water impervious and insulated flooring deck and floor for a basement.

2. Description of Earlier Related Developments

In order to improve the appearance and feel of a concrete floor, most people cover them with some type of flooring system. Traditionally, to create a subfloor for the concrete floor, an installer would first put down wood “sleeper” studs. Between each stud one had the option of then placing a foam board for insulation. With or without the insulation board, the subfloor would be finished with a sheet of plywood over top of the studs concealing the concrete floor below. With the subfloor now in place a finishing material could be applied to it to finish the floor, such as a carpet or hardwood. Typically, these subfloors were applied in a basement. In the event of a leak or water vapor penetrating the concrete floor, the subfloor being made of wood created a situation for mold and mildew growth and rot. An alternative to the “sleeper” stud plywood finishing system is to provide a free floating subfloor that consists of an upper layer and a lower layer. The upper layer being made of a sheet material such as plywood and the lower layer being made of a plastic that would not promote growth or rot. Such a system is disclosed in the U.S. Pat. No. 6,918,215. A problem with such a system arises in the fact that the plastic material provides no insulation. Accordingly, there is a desire to provide a subfloor system upon which a finished surface can be applied that does not mold or rot and that provides the insulation desired in applications with a concrete floor.

DETAILED DESCRIPTION OF THE EXEMPLARY EMBODIMENT(S)

FIG. 1 illustrates a flooring deck system 100 in accordance with an aspect of the disclosed embodiment. Although the aspects of the disclosed embodiment will be described with reference to the drawings, it should be understood that the aspects of the disclosed embodiment can be embodied in many forms. In addition, any suitable size, shape or type of elements or materials could be used.

According to the aspects of the disclosed embodiment, a flooring deck system 100 for application over for example a concrete basement slab 101 is provided. Although, the flooring deck system 100 of the disclosed embodiment will be described below with specific reference to application onto a concrete basement slab 101, in alternative aspects the flooring deck system 100 may be used with, and the features of the disclosed embodiment are equally applicable to installation on any desired type of subfloor. Referring to FIG. 1, a flooring deck system 100 is shown situated on a concrete basement slab 101. The flooring deck system 100 may be used for example to finish an unfinished basement and provide a more comfortable living space. By placing the flooring deck system 100 on the concrete basement slab 101, the deck system may provide, for example, an even surface offset from the slab and suited for placement of a finishing floor material 103 creating a finished floor 104. The flooring deck system 100 may also provide a surface that a finishing floor material 103 can more easily be attached to rather than the concrete basement slab 101.

The flooring deck system 100 may also serve to insulate the finished floor 104 and the basement interior as a whole. Typically, a concrete basement slab 101 effects a heat drain from the basement interior and the basement floor feels cold to the touch. By placing the flooring deck system 100 on top of the concrete basement slab 101 this effectively insulates the finished floor 104, reducing the heat lost from the basement interior and reducing the heat loss from the finished floor 104 so that when it is walked on it will not be cold to the touch.

Generally, accumulation of water in a basement is not uncommon, with the corresponding possibility for water damage to occur. Most homes maintain pipes to provide water to the home in the basement. When a pipe bursts the water usually ends up collecting in the basement. Water may also collect in the basement through ground water penetrating the concrete basement slab 101 and basement walls. If this happens, anything and everything in the basement is subject to getting wet and in turn becoming damaged, whether it be conventional wood “sleeper” studs rotting and losing structural integrity and any other conventional finishing floor material placed on the floor becoming damaged. The flooring deck system 100 protects the finished floor 103 from water damage, as it is water impervious and elevates the finishing floor material 103 off the concrete basement slab 101 where any water would collect. The flooring deck system 100 would remain unaffected by the water that has collected while protecting anything else that may be placed upon it by creating a barrier impervious to water between the concrete basement slab 101 and the materials to be protected.

Accomplishing these aspects of the flooring deck system 100 includes providing a plurality of flooring deck panels 102 and placing them on the concrete basement slab 101 in a manner that produces a uniform flooring deck system 100. These flooring deck panels 102 include a foam layer that provides the insulation for the room and the finished floor 104. The foam layer also provide structural integrity for the panels 102 allowing them to have the load bearing capacity of a floor without being, for example, damaged or buckling when a load such as a human or furniture is applied to the flooring deck system 100.

Referring now to FIG. 2, a partial view of the flooring deck system 100 is shown. The flooring deck system 100, as previously stated, includes a plurality of flooring deck panels 102. The flooring deck panels 102 include a first layer 201. The first layer 201 may be made solely of a substantially rigid sheet material such as magnesium oxide or any other suitable material including, but not limited to, substantially inorganic cement board. The first layer may alternatively be multiple layered rigid sheets or a composite layer stacked on a sheet of inorganic material to remain water impervious. The first layer 201 provides a surface where the finishing floor material 103 may be situated. The first layer 201 is generally rigid to help maintain structural integrity and prevent the finished floor 104 from bowing and buckling.

The flooring deck panel 102 also includes a second layer 202. The second layer 202 is made of a rigid foam material such as extruded polystyrene or any other suitable material including, but not limited to, expanded polystyrene, polyisocyanurate, expanded polyurethane, and extruded polyurethane. The second layer 202 is formed by cutting a block of the desired material the second layer 202 will be formed of and down to the desired size, using a hot wire cutting process or any other suitable manner in which to cut the block. The second layer 202 provides the insulative properties desired for the insulated flooring deck system 100. The rigid foam material may vary in thickness depending on desired insulative properties, the thickness range including, but not limited to, 0.5″, 1″, 2″, and 3″. As shown in FIG. 2, the second layer 202 provides structural support to the flooring deck panel 102 by having the load capacity, for example, of a floor. As may be realized, the substantially rigid first layer may serve to distribute local loads to the second layer, and the second layer carries the floor loads to the underlying concrete basement slab 101. The floor load capacity defined by the second rigid foam layer includes both static and live loads as gauged for a floor.

The second layer 202, as previously stated, is substantially inorganic and water impervious. When any water collects between the second layer 202 and the concrete basement slab 101, coming into contact with the second layer 202, the second layer 202 is not affected. The second layer 202 does not promote any growth of mildew or mold.

The flooring deck panels 102, may be formed in any suitable manner, for example, the first layer 201 and the second layer 202 may be joined together to form an integral panel. In order to join the first layer 201 to the second layer 202 any suitable methods may be utilized. These methods for example may include, but are not limited to, applying an adhesive to one or more of the rigid layers 201, 202 and joining the surfaces with adhesive together. Also, using an adhesive laminate between the two layers or a fastener may be another method to join the layers to one another.

Referring now to FIG. 3, a flooring deck panel 102 is shown. When installing the flooring deck system 100 into a basement, the flooring deck panels 102 may be connected together to create one uniform flooring deck system 100. The panels may be self-connecting, incorporating an integral coupling member in each panel as will be described further below. In order to connect the flooring deck panels 102, the first layer 201 or second layer 202 may be configured with an interlocking member, for example a tongue or groove of a rabbet type coupling configuration. Either of the first layer 201 or second layer 202 may have a tongue 302 protruding on one side of the flooring deck panel 102 and a groove 301 on the opposite side as seen in FIG. 3. The coupling configuration maybe molded into the second layer during its formation or alternatively, formed by removing excess material after the formation of the second layer by way of hot wire cutting or any other suitable way to remove the excess material. In an alternative aspect of the flooring deck panel 102, the flooring deck panel 102 may have a tongue 302 protruding from two adjacent or opposite sides of the flooring deck panel 102 and grooves 301 on the sides without tongues 302. The grooves 301 on each flooring deck panel 102 are configured to accept any tongue 302 of a subsequent panel and the tongues 302 on each flooring deck panel 102 are configured to interface with any complementing groove 301 of a subsequent adjoining panel. When interfacing, the flooring deck panels 102 are joined together to create a uniform flat surface that, as stated previously, can support a load such as furniture or a human and can have a finishing flooring material 103 applied to it if desired. The flooring deck panels 102 may interlock via any other suitable interlocking coupling configuration. Alternatively, each flooring deck panel 102, if desired, may be placed and abutted to the wall or an adjacent panel without interlocking at all.

Referring now to FIG. 4, the bottom surface 400 of the second layer 202 is shown. In order to effectuate drying and draining of moisture that may collect between the concrete basement slab 101 and the second layer 202 it would be beneficial to include a way for air to circulate and the moisture to flow freely beneath the flooring deck panels 102. One way in which to achieve these aspects includes, but is not limited to, adding a global drain and vent channel 401 to the bottom surface 400. These drain and vent channels 401 would provide a passage for which air could circulate and the moisture could drain away from the flooring deck system 100 preventing it from penetrating up into the second layer 202. The drain and vent channels 401 may be added to the bottom surface 400 by notching or carving the drain and vent channels 401 into the bottom surface 400 or any other way that may be suitable for creating a channel, for example, using a hot wire to melt the channels into the bottom. The drain and vent channels 401 may traverse the entire bottom surface 400 or a portion thereof and may traverse in any manner, such as in a diamond pattern as seen in FIG. 4. Alternatively, the drain and vent channels 401 may traverse in any pattern that is suitable for effectuating the ventilation and drainage desired including, but not limited to, a square pattern.

Referring now to FIG. 5, another exemplary representation of the bottom surface 400 in shown. In this aspect, along with the drain and vent channels 401, a merging channel 501 is shown. When laying the flooring deck panels 102, in order to create a more structurally stable flooring deck system 100, it may be best to stagger the flooring deck panels 102 in a way that would not create a single long seam where the flooring deck panels 102 connect. If the flooring deck panels 102 are staggered the ends of the drain and vent channels 401 from two adjacent flooring deck panels 102 may not directly match up. This would create a situation where an installer would have to manually line up the channels of adjacent flooring deck panels 102 to ensure that there is a continuous channel across the flooring deck system 100. Adding a merging channel 501 along a perimeter of the bottom surface 400 would enable the drain and vent channels 401 to merge and create the continuous channel and also eliminate the need for the installer to manually line up each drain and vent channel 401.

Referring now to FIG. 6, a block diagram 600 of a method of installing a flooring deck system 100 is shown. The method, as shown in block 601, includes an installer providing a first panel having a first layer and a second layer joined together that is configured to support both a static and live load gauged for a floor. The method, as shown in block 602, also includes an installer providing a second panel having a first layer and a second layer joined together that is configured to support both a static and live load gauged for a floor. The method, as shown in block 603, subsequently includes an installer then interlocking both the provided panels to form the flooring deck system 100. Finally, the method, as shown in block 604, includes the installer engaging the formed flooring deck system 100 with the concrete basement slab 101 completing the system. Alternatively, the system may include a finishing floor material 103 to finish the basement.
