Waterproof cementitious furniture method

Abstract

A furniture construction method comprising cementitious sheets for a layered method of adhering various layers of cementitious board to form a solid waterproof piece of furniture with the cementitious layers. These layers of cementitious sheets form a laminate which has structural integrity to provide for vertical members of support for horizontal members comprising a piece of furniture.

A method of constructing said laminate is to apply water submersible laminating glue to cementitious board, after cutting cementitious board to desired size and cure for 6 hours. Next is to trim said laminate to final size requirements. A coat of epoxy is applied to all surfaces.

Cementitious boards are mainly cement bonded particle boards and cement fiber. There are various types of cementitious boards that are included in the present disclosure for the construction of furniture and other similar construction.

DETAILED DESCRIPTION OF THE INVENTION

[0022] Incorporated by reference is Provisional Patent U.S. 63,205,411 filed Dec. 11, 2020, by inventor and applicant Thomas S. Martin.

[0023] Presented in this disclosure is of the present invention is a construction method comprising cementitious sheets for a layered method of adhering various layers of cementitious board to form a solid waterproof piece of furniture with the cementitious layers. These layers of cementitious sheets have structural integrity to provide for vertical members of support for horizontal members comprising a piece of furniture.

[0024] Cementitious boards are mainly cement bonded particle boards and cement fiber. There are various types of cementitious boards that are included in the present disclosure for the construction of furniture, sinks, fireplace mantels and other similar construction.

[0025] One such cementitious board are cement bonded particle boards that have treated wood flakes as reinforcement, whereas in cement fiber boards have cellulose fiber, which is a plant extract as reinforcement. Cement acts as a binder in both cases. The fire resistance properties of cement bonded blue particle boards and cement fiber boards are the same. In terms of load bearing capacity, cement bonded particle boards have higher capacity than cement fiber boards. Cement particle boards are manufactured from ¼ to 1 9/16 inches in thickness making it suitable for high load bearing applications.

[0026] In this disclosure the application of cementitious board for furniture construction will vary as to required strength of the furniture members.

[0027] The cementitious boards disclosed in this invention are made of a homogeneous mixture and hence are formed as single layer for selected thickness. Cement fiber boards are more used in decorative furniture and can be manufactured from ⅛ to 13/16 thickness. Fiber boards are made in very thin layers, making it adaptable for varying furniture piece members. Manufacturers use additives like mica, aluminum stearate and other additives to achieve certain board qualities. Typical cement fiber board is made of approximately 40-60% of cement, 20-30% of fillers, 8-10% of cellulose, 10-15% of mica. Other additives like above mentioned aluminum stearate and PVA are normally used in quantities less than 1%.

[0028] Cement board has long term performance as it will not allow mildew or physically break down in the continued presence of moisture or leaks. This makes cementitious board used in the present disclosure ideal for sinks and other areas around the presence of water.

[0029] There is a class of cement board strictly constructed of a Portland cement-based core with glass fiber mat reinforcing both faces. These panels can be immersed in water without any degradation. These panels do not require the sealing of edges and penetrations to maintain their structural integrity. These Portland cement-based boards are smaller in size compared with other cementitious boards.

[0030] Cement board is a combination of cement and reinforcing fibers formed into sheets, of varying thickness that are typically used as a tile backing board. Cement board can be nailed or screwed to wood or steel studs to create a substrate for vertical tile and attached horizontally to plywood for tile floors, kitchen counters.

[0031] Cement board adds impact resistance and strength to a surface as compared to gypsum board or other construction boards. Cement board is also fabricated in thin sheets with polymer modified cements to allow bending for curved surfaces.

[0032] Presented in this disclosure is of the present invention is a construction method comprising cementitious sheets for a layered method of adhering various layers of cementitious board to form a solid waterproof piece of furniture with the cementitious layers. These layers of cementitious sheets have structural integrity to provide for vertical members of support for horizontal members comprising a piece of furniture. FIG. 1 is an isometric drawing of the laminate 10 used throughout the various construction of the following FIGS. 1 through FIG. 8. Shown in FIG. 1 is a bottom cementitious board 5 adhered to a top cementitious board 5, said boards are adhered by laminating glue 3. On the surface of said top cementitious board 5 is a layer of epoxy 2.

[0033] A method of constructing the laminate 10 of FIG. 1 is to apply water submersible laminating glue 3 to cementitious board 5, after cutting cementitious board 5 to desired sizes and cure for 6 hours. Next is to trim laminate 10 to final size requirements.
