The present invention relates to a self-contained modular home which can be removed from the foundation system. More particularly, the present invention relates to a self-contained modular home comprising a first section, a second section and a top section, each section having an interior which is 100% complete and an exterior which requires only siding or other exterior finish for completion. The three sections of self-contained modular home are designed to be transported on a low boy trailer or other transport system to a permanent foundation site.
The construction and assembly of modular homes is well known in the prior art. Typically, the standard modular home arrives at the building site in component modules that are about 80% to 90% complete, thereby requiring the builder to finish the modular home at the building site. Each component module of the standard modular home usually is set on the foundation with a crane, using straps and/or cables which cradle the outer side and under side of the home. The typical modular home then is attached to a conventional foundation such that a crawl space or air space of at least eighteen inches (18″) is created under the home in order to meet current building codes. Following the setting and securing of the component modules to the foundation, a roof system is attached to the modules. Most modular homes utilize a tilt up roof system that is cumbersome and very time consuming in setting up. In contrast, the present invention provides a modular home that is 100% finished prior to leaving the factory, incorporates a unique steel cable lifting system within the floor system which enables the modules to be set on the foundation with or without the use of a crane, uses a concrete slab foundation to which the modular home is bolted, thereby decreasing the crawl/air space to 1½″ and employs a one half truss system with a separate roof cap.
Accordingly, it is an object of the present invention to provide a self-contained modular home that can be quickly and easily installed on a permanent slab foundation and that can be removed from the foundation system at a later date.
It is another object of the present invention to provide a self-contained modular home comprising a first section, a second section and a top section, each section being 100% finished except for exterior siding or other exterior finish when it leaves the factory.
It is also an object of the present invention to provide a self-contained modular home that can be bolted to a permanent foundation slab in such a manner that only an inch and one half (1½″) air space is created.
It is a further object of the present invention to provide a self-contained modular home having a roof truss system comprising a half truss with a separate roof cap attachment.
It is an additional object of the present invention to provide a self-contained modular home having a plumbing system that is 100% complete when it leaves the factory.
It is still another object of the present invention to provide a self-contained modular home which can be bolted to a permanent foundation and be connected to water/sewer service and electrical service within a period of hours, rather than days.
It is yet another object of the present invention to provide a self-contained modular home which can be set onto the foundation without the use of a crane.
Additional objects, advantages and novel features of the invention will be set forth in part of the description which follows, and in part will become apparent to those skilled in the art upon examination of the following specification or may be learned by practice of the invention.
The present invention will be better understood with reference to the appended drawing sheets, wherein:
The present invention relates to a self-contained modular home 100 as shown in
The foundation is an integral part of the present invention. The foundation can be in the form of a concrete slab, curtain wall, pier or other permanent foundation onto which the self-contained modular home can be bolted. Preferably, the foundation is a concrete slab foundation. Referring now to
A plurality of structural bolts 105 are placed horizontally through the foundation forms 102 to establish permanent attachment points in the permanent foundation 101 (hereinafter sometimes referred to as the “concrete slab” or “slab”). More particularly, a first end 105a of each of the plurality of structural bolts extends within the area encompassed by the foundation forms. Once the concrete is poured and cured, the foundation forms are removed and the first end of each of the plurality of structural bolts remains embedded in the concrete slab and the second end 105b of each of the plurality of structural bolts extends outside along the perimeter 106 of the permanent foundation. As shown in
Each of the first foundation system 128 and second foundation system 158 comprise a floor joist 108, a plywood floor 109 and a bottom plate 110. The floor joist 108 of the modular home is composed of 2″×8″ treated material, such as studs having a belly board vapor barrier attached to the bottom thereof. When the modular home 100 is set on top of the treated sill 107, a one and one half inch crawl/air space 118 is created underneath the modular home foundation since the 2″×6″ treated material actually are one and one half inch thick. The modular home then is bolted to the slab by a plurality of structural steel plates 112 (hereinafter sometimes referred to as “steel straps”). Each steel strap first is attached to the second end 105b of one of the plurality of structural bolts 105 extending out of the foundation. Lag screws 114 are used to further attach the modular home into the floor joist 108, and into a 2″×6″ attachment stud 116 which is used in addition to the conventional exterior studs 117 but which are turned sideways to the exterior of the wall for stronger attachment. Lag screws 114 also are used to attach the 2″×6″ sideway studs 139 to each of the conventional exterior studs 117. All of the structural bolts 105 and lag screws 114 can be removed at a later time and the home can be moved to another location if desired.
In addition to the steel strap securing arrangement, a bottom steel plate 110, preferably a 3″×6″ steel plate, is nailed two foot on center to the treated sill 107 and the floor joist 108. Both these attachment arrangements provides the secured modular home with 160 mph wind protection, which is far greater than the typical 80 mph to 100 mph offered by most site or stick built homes currently on the market.
As described above, the foundation system of the present invention creates an air space 118 of approximately one and one half inch between the slab and the bottom of the 2″×8″ floor joists. This air space can be vented with one or more foundation vents 119 as shown in
Typically, a modular home is set with a crane using either cables or straps that are placed around the side and bottom of each component module. The lifting system used to set the modular home onto the permanent foundation is novel to the present invention. More particularly, and referring to
The roof truss system of the self-contained modular home of present invention comprises a half truss with a separate roof cap attachment 180 as shown in
Referring now to
The second section 150 is the living section, comprising a family room, kitchen and dining area and utility room, the living section also is completely finished on the inside prior to leaving the factory. The finished living section includes a self-contained heat and air system including duct work, plumbing contained within the double utility wall and floor joist, eight foot sheetrock walls, flooring (e.g. carpet/vinyl), a complete kitchen including cabinets, sink, dishwasher, stove and refrigerator, and a front porch.
The plumbing system of the self-contained modular home also is novel to the present invention. All of the plumbing is 100% complete prior to leaving the factory. The plumbing system is built inside the 2″×8″ floorjoist and travels with the home. The plumbing extends to outside walls 125 and 155 and then is turned downwardly toward the corresponding recessed area 103 cut out of the slab. In the first section 120, a three inch (3″) pipe is used. The hot and cold water lines extend to the marriage wall 140 at the hall bath vanity. Under the hall bath vanity and on the opposite marriage wall is a removable access panel exposing a 15″×15″ opening within which the hot and cold water lines can be connected together in about few minutes. In the second section 150, a two inch (2″) pipe is used. A waste pipe is introduced from the street to the recessed area 103 disposed in the slab. Once the home is set on the slab, two elbow joints are used to connect the house plumbing to the waste pipe. This operation can be performed in about ten minutes.
The marriage wall 140 comprises five painted (finished) doors which are hung in place with the casing on one side (such as the second section side) and five painted (finished) door casings on the other side. Once the first section 120 and second section 150 are bolted to the slab, these five entries are completed simply by securing a pre-finished/painted 1″×6″ trim board over the marriage wall joint. The trim board covers the joint and also acts as a door stop, rather than the ¾″ door stop currently used.
The self-contained modular home also contains a whole-house fresh water cut offthat is place in line from the street to the house. The cut off valve is located in the utility room for easy access in the event of an emergency.
The self-contained modular home of the present invention is designed to be less than thirty two feet (32′) wide. Thus, both the first section 120 and second section 150 are less than sixteen feet (16′) wide. There are two reasons for designing a modular home of this width. First, each module can be transported on low boy trailers and meets the sixteen (16′) maximum width for highway use. Second, most inner city lots are fifty foot (50′) wide. Thus, a thirty two foot wide modular home of the present invention is suited perfectly for such a lot size, including side line setbacks.
In operation, once the modular home of the present invention arrives at the construction site, the home can be set and bolted to the concrete slab, made weather tight, connected to the local plumbing and electrical services and an be operational in about three hours.
The self-contained modular home of the present invention also can include a car port 200. Referring now to
The self-contained modular home of the present invention also can include an attached garage 300. Referring now to
