Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
   This application claims the benefit of Provisional Patent Application Ser. No. 60/802,473 filed May 22, 2006 by Douglas Overmyer, Jr. and Russell Matthew Wilber and titled “Special Cement-like Coated Mobile Building and Process to Manufacture”. 

   FIELD OF INVENTION 
   This invention relates to buildings, especially mobile homes and the process to construct the building. Particularly, this device is a special high durability building that has no materials subject to rotting or decay. This is achieved with available products combined in a new manner with specific process steps that will be demonstrated below. 
   FEDERALLY SPONSORED RESEARCH: Not Applicable at this time although HUD and FEMA are aware of this new invention. 
   SEQUENCE LISTING OR PROGRAM: Not Applicable. 
   BACKGROUND 
   Field of Invention and Prior Art 
   The new Special Cement-like Coated Mobile Building device and Process to Manufacture described in this specification is a building device and method that is designed to easily and quickly provide a durable and economical alternative to current manufactured and mobile homes. 
   A. Introduction of the Problems Addressed 
   The concept of an improved shelter gained momentum with the vision of such a concept in terms of disaster shelters currently available to victims, responders and evacuees. This feature is important for disaster relief and has the attention of HUD and FEMA for use in disaster relief. As will be explained in detail below, this Cement-like Coated Mobile Building and the process to construct uses available materials to answer the need for durable, lower cost construction in many areas. 
   B. Prior Art 
   Historically, manufactured and mobile homes have been built with wood, metal and other materials. The natural materials such as wood have been susceptible to rot and decay with time and the presence of moisture and temperature variations. Likewise, the surface materials of the walls, ceilings and some roofs have not been resilient or durable enough to withstand exposure to high use and the natural elements. The maintenance to keep these types of buildings in good condition has been excessive, especially when exposed to migrant tenants with short rent and lease occupancy. Several attempts to improve the building system have been made, but with little success. In use, the prior art devices were often complex, difficult to install and limited in improving durability. The new Special Cement-like Coated Mobile Building device and Process to Manufacture addresses these limitations and provides a solution to the stated problems. 
   Examples of some prior building systems with panels and the like begin with U.S. Pat. No. 4,645,374 issued to Erickson, et al (1987). This teaches a plurality of upright panels and a top with a connector to secure the objects. The use of center structures with the foam and cementitious coatings as utilized with the innovative Special Cement-like Coated Mobile Building device and Process to Manufacture is not mentioned or anticipated. Another U.S. Pat. No. 4,691,490 issued to Leaver (1987) presents an earthquake useful design that incorporates Cementitious materials in panels that are connected with complex flanges and fasteners. The modular panel and panel assembly have upstanding edges that form flanges to orient and contain part of the panel. The complex system relies on self supporting and individual resistance by each successive panel. 
   Another U.S. Pat. No. 4,841,705 issued to Fuhrer (1989) provides a building wall covering system for application to a wall support such as masonry block. The system comprises a layer of insulative material and an overlying layer of matting which is attached to the wall support structure. The idea claims to provide some structural strength by the matting to the cementitious coating material applied thereto. In the U.S. Pat. No. 4,858,398 issued to Ricchini (1989), a prefabricated construction system is taught. The modular building construction system uses rectangular wall and roof panels and triangular gable panels. The panels are secured together with simple fasteners inserted through aligned openings in adjacent edges of the panels and turned to lock them in place. No cementitious coating or interior and exterior coating is taught. Individual panel are taught unlike the series of contiguous core material as in the Special Cement-like Coated Mobile Building device. 
   Other prior art includes the U.S. Pat. No. 5,172,532 issued to Gibbar, Jr. (1992). This is another prefabricated polymer and concrete building wall panel which teaches generally a section of polystyrene, as a slab, which is sculpted to form grooves by hot wire cutting or other cutting means, and into which reinforcement rods may be located. This is in preparation for the pouring or pumping of concrete therein, to form a concrete built skeletal structure for reinforcing the panel. The panels are erected into a building wall structure. Insulative materials may be applied over the open grooved side either before or after concrete is poured therein. The grooves cut into the polystyrene panel may be a design shaped for enhanced reinforcement to strengthen the panels. A mobile home building system is featured in U.S. Pat. No. 5,218,792 issued to Cooper (1993). The mobile housing structure is provided having a pair of side walls with vertical support posts extending upward from a chassis and connecting to an elongated side wall honeycomb configuration. A modular roof section is formed of a sandwich construction with Styrofoam block members adhesively connected to panels. The roof joint members can be riveted to the side joint members. There is no mention of cementitious coatings, plastic-like structural members, or contiguous Styrofoam that forms a running wall. Surface durability appears less an objective than weight of the overall design configuration. 
   In U.S. Pat. No. 5,398,468 issued to Erickson (1995), a panel and connector assembly building system is taught. The system is comparatively complex to the Special Cement-like Coated Mobile Building device. Erickson teaches a series of upright panels, joined together with vertical connectors and horizontal inserts. Adjacent edges of the panels have complimentary beveled faces and aligned grooves. Special configuration of the connectors and special flanges cooperate with the panel configurations to hold the panels in a structural engagement. Another building system of prefabricated panels is demonstrated by U.S. Pat. No. 5,471,804 issued to Winter, IV (1995). The system uses prefabricated building panels with a foam core. The fastening components and raceway components used with the panels are essentially placed during the prefabrication. The method for the assembling of a building incorporates locking mechanisms integrated with a raceway system. This system connects wall panels together in edge-to-edge relationship to form walls. Further complexity is shown with the ram-lock and cam-lock devices. No description or anticipation of cementitious coating for strength or surface durability is taught. 
   In U.S. Pat. No. 5,524,400 issued to Schmechel (1996) a wall assembly is shown. The wall assembly utilizes a plurality of panels having preformed grooves and supports which interface with these grooves. Supports are positioned within the various grooves of each of the panels and are interconnected. These panels are made from Styrofoam and the supports are generally U-shaped, steel studs. Several panels may be positioned adjacent to each other to provide the structure. Surface coating to strengthen the overall structure is not addressed nor is mobility mentioned. The overall system is complex as compared to the Special Cement-like Coated Mobile Building device. Another building structure is taught in U.S. Pat. No. 5,584,151 issued to Abou-Rached (1996). The system is a very complex structure for earthquake, wind and fire resistance devised of pre-fabricated framed building panels. The frame members are connected together at the perimeter of the panels. There are series of fasteners and connector plus configured voids which may ultimately form a web of steel and concrete when the entire sections are cast with a substance. The connections absorb and distribute seismic forces to the entire structure and some frame members act to absorb residual seismic forces reaching the individual panels. 
   In the U.S. Pat. No. 5,758,463 issued to Mancini, Jr. (1998) a composite modular building panel is shown and taught. These are fully pre-cast panels, not structures of Styrofoam built in place and then coated. The modular building panel is a single, monolithic, planar slab formed primarily of cellular concrete and having a pair of parallel linear members. The slab extends between the webs of the linear members. It does not teach the complete structure for a mobile building nor does it teach exterior and interior coating for strength. 
   Next in U.S. Pat. No. 5,953,875 issued to Harkins (1999), a slide-in building insulation system is taught. There are shown a set of slide tracks secured to the wall and roof system. The insulative material is then held in place. This has insulative properties but is considerably unlike the Special Cement-like Coated Mobile Building device. There is no continuous building process anticipated. In the U.S. Pat. No. 6,735,917 issued to Notermann (2004), a connected frame structure and method of connecting frame members is taught. The interlocking joint structure has a tubular frame member with a key-shaped slot to slidably accommodate a second elongated T-shaped frame member. An adhesive is used to bond the first and second frame members together. The system anticipates sectional panel to interlock and shows no anticipation as to a cementitious coating to add strength to the overall structure and durability to the surface. 
   As far as known, there are no housing or building products or processes at the present time which fully meet this need with as few of components and superior operation as the present Special Cement-like Coated Mobile Building device and Process to Manufacture. It is believed that this device is made with fewer parts, of a more durable design, and with much less expense than any previous mobile housing or building device. The overall combination and configuration is not demonstrated or anticipated by other patents on their face. 
   SUMMARY OF THE INVENTION 
   A Special Cement-like Coated Mobile Building device and Process to Manufacture has been developed for use to create durable buildings not subject to normal decay and rotting. The new Special Cement-like Coated Mobile Building permits the construction of mobile homes and other buildings with minimal or no use of non-durable materials such as wood, nails, screws and others. Specifically, the preferred embodiment of the Special Cement-like Coated Mobile Building device is essentially comprised of a base or chassis, an expanded poly styrene foam, structural members (of various materials and shapes) inside the foam and a cement based material sprayed on the exterior of the foam. The configuration is such that the walls, floor, and roof are rigidly attached to each other yet maintain good flexural strength to resist wind loads and temperature changes. The materials are easily processed to provide many other optional features within the normal course of constructing a mobile home and other buildings. The floor plans for a traditionally built mobile home or other building are easily achieved with lower costs and higher strength and durability as explained in detail below. 
   The new use of a process is to spray a cementitious polymer-based material onto a substrate of expanded polystyrene foam walls, flooring, interior, and roof structures. The process yields a durable, reusable design that is easily deployed and made livable for as long as may be necessary. 
   The newly invented Special Cement-like Coated Mobile Building device features very few parts and may be built quickly in the process described below. In operation, the new Special Cement-like Coated Mobile Building device may be easily transported to wherever it is needed and quickly attached to existing utilities or special emergency systems as required. 
   Shelters are designed with an exterior and interior that is coated with a concrete based substance. These surfaces will withstand severe punishment without need of repair or repaint. The walls of the shelters are formed with no wood or other material that may decay or rot while being used. The resilience and properties of the interior wall, floor and ceiling surfaces will provide a unit that will be reusable when faced with only normal wear and tear. This surface will also allow for ease of cleaning and a quick turn-around time for people in need. 
   Objects and Advantages 
   There are several objects and advantages of the Special Cement-like Coated Mobile Building device and Process to Manufacture. There are currently no known building devices or processes that are effective at providing the objects of this invention. 
   One advantage and object of the present invention is that it is very durable. The cement based material that is sprayed and troweled on the entire exterior resists moisture, humidity, mold and abnormal wear and tear. Abnormal wear and tear is often seen in areas of temporary, housing for disaster relief. The occupants do not own the building and sometimes do not care as much for the building as one they will be in permanently. This ability to withstand severe punishment reduces the need of repair or repaint of the units before re-use. This durable unit, therefore may be re-used for disaster relief. 
   Another advantage is that the Special Cement-like Coated Mobile Building resists shocks, fire, wind, and other natural or un-natural calamities. The whole structure is securely connected through the cement-like coating on exterior and interior surfaces of the walls, floor and roof. This structural shell creates a very strong building unit to withstand much environmental abuse from nature. 
   A further advantage is that it is less labor intensive to build, uses simple processes to manufacture, uses fewer parts, and uses common, non-natural materials. Therefore the process and resulting device is less expensive. 
   A somewhat hidden advantage is that it is lighter when finished. The foam, while strong with the outer cementitious material, is lighter than the normal wood and sheet metal. This lighter unit means there is a less expensive transportation cost. 
   Finally, other advantages and additional features of the present Special Cement-like Coated Mobile Building and Process to Manufacture device will be more apparent from the accompanying drawings and from the full description of the device. For one skilled in the art of building devices and processes to manufacture, it is readily understood that the features shown in the examples with this mechanism are readily adapted to other types of building devices and processes.

   DETAILED DESCRIPTION OF PREFERRED EMBODIMENT 
   The present device is a mechanism for constructing a very durable mobile home and other buildings called a Special Cement-like Coated Mobile Building  31 . The preferred embodiment of the device is essentially comprised of a base or chassis  50 , an expanded poly styrene foam  47 , structural members  46  (of various materials and shapes) inside the foam and a cement based material  68  sprayed on the exterior of the foam (and then finished with a trowel, brush, or other means). The configuration is such that the walls, floor, and roof are rigidly attached to each other yet maintain good flexural strength to resist wind loads and temperature changes. The materials are easily processed to provide many other optional features within the normal course of constructing a mobile home and other buildings. A person having ordinary skill in the field of manufactured housing and general construction appreciates the various means that may be used to physically permit this Special Cement-like Coated Mobile Building  31  to be produced and utilized. 
   The improvement over the existing art is providing a device that:
         a. is very durable.   b. may be re-used for other disaster relief.   c. resists shocks, fire, wind, and other natural or un-natural calamities.   d. is less expensive.   e. is lighter when finished and   f. is less expensive to transport.       

   There is shown in  FIGS. 1-13  a complete operative embodiment of the Special Cement-like Coated Mobile Building device  31 . In the drawings and illustrations, one notes well that the  FIGS. 1-13  demonstrate the general configuration and use of this invention. The preferred embodiment of the device is comprised of only a few parts as shown in the drawings. These structural members or parts are comprised of and include, but are not limited to, a base or chassis, an expanded poly styrene foam, structural members (of various materials and shapes) inside the foam and a cement based material sprayed on the exterior of the foam. The configuration is such that the walls, floor, and roof are rigidly attached to each other yet maintain good flexural strength to resist wind loads and temperature changes. The materials are easily processed to provide many other optional features within the normal course of constructing a mobile home and other buildings. Various important features of these member components are delineated in  FIGS. 1-13  of the drawings and are described below in appropriate detail for one skilled in the art to appreciate their importance and functionality to the Special Cement-like Coated Mobile Building device  31 . 
   The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate an embodiment of the Special Cement-like Coated Mobile Building device  31  that is preferred. The drawings together with the summary description given above and a detailed description given below serve to explain the principles of the Special Cement-like Coated Mobile Building device  31 . It is understood, however, that the Special Cement-like Coated Mobile Building device  31  is not limited to only the precise arrangements and instrumentalities shown. 
     FIG. 1  is a depiction of the general device.  FIG. 1A  is a sketch of the general wall section  32 . Here the various members to build a typical wall are shown. These are described below.  FIG. 1B  is a drawing of the model  31  of the Special Cement-like Coated Mobile Building. This model serves as a tool to further describe the components and features in the descriptions below. Next is  FIG. 1C  is a layout  33  of the floor plan for a Cement-like Coated Mobile Building  31 . 
     FIGS. 2A through 2C  are the same general sketches and drawings of the device with components identified and depicted.  FIG. 2A  is a sketch of the general wall section  32 . Here the expanded polystyrene foam (EPS)  47  sections are shown as part of the main structural base for a wall section  32 . This section may be various widths. The preferred size is two layers, 3 inches thick to provide a total of six inches of foam with an outstanding “R” factor for insulation for heating and cooling. One skilled in the art of wall systems well appreciates that the foam might be of other equal propertied materials and may, as technology advances, embrace new composite materials not yet released or even developed for the building trades. However, these other foams and materials are well within the spirit and scope of components for this device known as the Special Cement-like Coated Mobile Building  31 . 
   Within the wall section  32  are structural members  46 . These members  46 , like reinforcing steel bars for reinforced concrete, serve to strengthen the whole wall system  32 . Anticipated for the structural members  46  are various materials including, but not limited to, plastic (PVC, BUTYRATE, STYRENE, ACRYLIC, COPOLYESTER, and the like), metal (steel, aluminum, brass, etc), and other composite materials of equal or greater strength. The structural members  46  will be connected to other members by means of a connector or fusing process  48 . Here a typical connector/adaptor may be used to join members  46  or a fusing/connecting process such as adhesion, welding, brazing and the like. Various members to build a typical wall are shown. These are described below. The exterior vertical wall members  32  are connected directly to the chassis or base  50  through apertures  70  (openings) in the chassis  50 . These structural members  46  are held to the chassis  50  by means of a press fit, an adhesive (not shown), or a flange  49 . Anticipated by this concept are some adhesion or fusion means that require no flanges  49 A. Finally, the actual width and length, as well as the thickness, of the EPS may vary for different requirements per engineering and architectural plans. 
   In  FIG. 2B  is a drawing of the model  31  of the Special Cement-like Coated Mobile Building. This model serves as a tool to further describe the components and features in the descriptions below. Here several components are depicted including the roof section  42 , the roof peak  51 , the sidewall  55 , and the corners  54 . Additionally, the entry door  53  and windows  52  are depicted. These features are anticipated as part of the normal features required for mobile homes and other buildings that use the new cement coated foam building system. Next is  FIG. 2C . This is a layout  33  of the floor plan for a Cement-like Coated Mobile Building  31 . Shown are the front  36 , the rear  35 , the kitchen end  38  and the opposite of the kitchen end  39 . 
     FIG. 3  is the general architectural drawings  34  of the floor plan  33 , elevations  35  and  36 , end views  38  and  39 , and section  37  of the Cement-like Coated Mobile Building  31 . These are each discussed in detail in the paragraphs below. 
     FIG. 4  is a floor plan  33  with many of the components that comprise the Cement-like Coated Mobile Building  31  identified. One skilled in the art of mobile home and building floor plans realizes and appreciates the plethora of plans that a builder might provide. These various options and sizes are anticipated and fall within the scope and spirit of this building device and method or process to construct. Here, many of the features and options for the Special Cement-like Coated Mobile Building  31  are demonstrated. The windows  52  are shown in various locations. These may be of any size specified and fit easily into the foam/cement wall of the Special Cement-like Coated Mobile Building  31 . Likewise the entry doors  53  may vary in location, quantity and size. Next, the exterior wall  55  and corner  54  are shown. The interior walls  44  and interior doors  56  are also demonstrated. Again, this layout has infinite combinations and permutations, yet is still anticipated in the scope and spirit of the concept behind the Special Cement-like Coated Mobile Building  31 . 
   Other features of this layout  33  include the depictions of the various rooms. Included are the kitchen/living area  58 , the bathrooms  61 , the bedrooms  62  and the large or master bed room  65 . Built in features in these various rooms include the structures for the corner bench  57 , the seat and kitchen table  59 , the counters  60 , bed platforms  63  and  63 A and closets and storage means  64 . All of these features mentioned are placed prior to spraying the cement-like material  68 . This provides these features with a very tough and durable finish. After spraying the material  68 , the surface may be troweled, brushed and even coated with other materials to provide the desired finish to the surface. This is discussed further in the description of  FIG. 8 , below. One skilled in building and layouts appreciates these are examples and not limitations to the Special Cement-like Coated Mobile Building  31 . 
     FIGS. 5A  and B are elevations of the Cement-like Coated Mobile Building device  31  with features noted. In  FIG. 5A , the rear side elevation is shown. Here the windows  52 , the ends  38  and  39 , the wheel and axle system  66 , the side walls  55 , the roof section  42  and the peak  51  are demonstrated. These are all described in detail in the section drawings, below. In  FIG. 5B , the Front elevation, these same features are shown as well as the entry doors  53 . 
     FIGS. 6A through 6C  are the End views ( FIG. 6B and 6C ) and a section view ( FIG. 6A ) of the Cement-like Coated Mobile Building  31  with additional components identified. The trailer tongue or kitchen elevation  38  is shown in  FIG. 6B . This sketch shows the end windows  52 , the roof section  42 , the peak  51  and the wheel and axles  66 . Similarly, the opposite end to the kitchen  39  is shown in  FIG. 6C . 
   In  FIG. 6A , a cross section of the trailer is shown. Here several important and significant components and features are demonstrated. The wheel and axle system  66  supports the chassis or base  50 . In turn, the pre-sprayed floor panel  83  is placed onto the expanded wire mesh  69  that has been rigidly attached (by a connection means such as welding or fastening) to the chassis  50 . In turn the exterior walls  55 , the vertical columns  46 B and the interior walls  44  are placed onto the chassis  50  or mesh  69  and floor panels  83 . One notes that the structural members  46  run within the EPS foam  47 . In turn the roof  42  is supported by the columns  46 B and ridge beam  46 A 
     FIG. 7  is a top view  40  of the base or chassis  50  upon which the Cement-like Coated Mobile Building  31  is built. Onto the chassis  50  or base is a wire mesh of expanded metal  69 . Likewise, the chassis  50  have specific apertures  70  to receive the structural members  46  (not shown) that run interior to and reinforce the exterior walls  55 . Specific apertures  70  are designed to receive structural members  46  and then secured to one another by press fit, fusion, welding, adhesive or other fastening means. 
     FIGS. 8A through 8C  are the wall sections with components identified. In  FIG. 8A , a sidewall  32  is shown which is identical to the view shown in  FIG. 2A , above. It is repeated here for easy reference to the other figures shown here. The description of  FIG. 2A  is incorporated here by reference.  FIG. 8B  is a cross section  41  of a typical wall section. The structural members  46  are centrally located between two sections of EPS  47 . The members  46  are glued or connected to the EPS  47  by an adhesive or equal. The location for the members  46  is pre-located in the EPS  47  by a pre-process means such as hot wire cutting, molding, or heat melting the cavity or recess into each half of the wall sections  47  of the EPS material. The member  46  is then placed between the EPS  47  as the assembly is made. Note the connection means  48  between horizontal EPS panels. 
   After the wall is erected, the surface of the EPS  47  is sprayed with a cement-like material  68  such as Permacrete™ or the like. An alternative means for the external coating is to pre-spray the surface of the EPS  47 , then embed a mesh  72 , and then final spray the cement-like material  68 . In all cases, after the coating  68  is applied, the surface is then troweled or brushed. For some surfaces, a patterned array or template may be used to give a common style and color to the surface. Finally, in some instances, such as for counter tops, an acrylic finish may be incorporated to provide FDA approved food grade finishes. The cement coating  68  as a one-step, pre-spray or final spray is a resilient, cementitious material that has strong flexural strength and rapid curing. 
   One such example of a suitable cementitious material (offered as an example but not as a limitation) is known as Permacrete™. Further exemplary data about a suitable example of a cementitious material such as Permacrete™ (or the like) includes a three-part, acrylic polymer cementitious resurfacing system of over 6000 PSI compressive strength that provides an architectural, load-bearing surface. The surface is sealed and non-porous, resists chemicals and withstands freeze-thaw cycles as well as intense heat and ultraviolet sun rays. The coating material can easily be applied over such existing surfaces as concrete, aggregate, masonry, steel, asphalt, or foam. The mix includes A matrix mix of high early-strength concrete compounds and specially blended additives; a chemical bonding additive; and acrylic resin sealer (water based) application(s). The material may have color and texture built into the mixture. It is normally sprayed or troweled onto the accepting base surface and then lightly troweled to finish the surface. The application results in an outstanding, durable and attractive surface which is amazingly easy to maintain with normal household detergents. Safety considerations are enhanced by the increased slip resistance of the materials for the floor surfaces. 
   Example architectural specifications for an exemplary (but not limiting) cementitious coating is shown in TABLE A.

   Other materials are available that may, (by simple empirical test for strength, flexibility, moisture resistance, and other engineering characteristics)prove suitable. Anticipated in the scope and spirit of materials to accomplish this Special Cement-like Coated Mobile Building  31  are other composite materials that will equal or exceed the properties of Permacrete™. Use of the mesh  72  is the preferred process for this Special Cement-like Coated Mobile Building  31 . The mesh  72  is a cloth or mesh “fabric” made of Fiber Glass. Alternatives of other composite materials, metal screens, nylon mesh, and other cloths may be equally suited and anticipated in the scope of this device with appropriate empirical testing. However, natural materials, subject to decay or rot are not recommended for this embodiment. 
   In  FIG. 8C , several structural members  46  are shown and denoted as various members  71 . Here, the internal structural members  46  are not limited to a specific material or structural shape. One skilled in the art of structural members realizes and appreciates various plastics (PVC, BUTYRATE, STYRENE, ACRYLIC, COPOLYESTER, and the like), steels, other metals, and other composite materials may fully support the scope of some of the components for the Special Cement-like Coated Mobile Building  31 . The various shapes are shown in the  FIG. 8C  and the following Table B.

     FIGS. 9A through 9C  are some examples of roof peak optional embodiments for the Cement-like Coated Mobile Building  31 .  FIG. 9A  is the preferred embodiment of a peak  76  without any cover or cap. The support means of the columns and beams are described in  FIG. 10A , below. Here, the empirical tests show that the cement coating  68  such as Permacrete™ or the like provides adequate expansion and contraction adaptability to remove any need for a cap or cover. As an alternative to applying just the cementitious materials  68 , an alternative moisture prevention sealant may be applied to the roof and/or exterior sidewalls. Further, in  FIG. 9B , an alternative embodiment shows a roof cap  77  being placed along the ridge of the roof. While not expected to be required, this alternative embodiment may have some usefulness for large buildings or the plethora of other floor plans than those exemplified in the present descriptions. In  FIG. 9C , another embodiment  42 B showing a radiused peak  78  is shown. This configuration may relieve the stresses commonly present with abrupt angular connections. 
     FIGS. 10A through 10F  are depictions of wall elevations and sections that show various components of the Cement-like Coated Mobile Building  31 . In  FIG. 10A , the typical column and beam cross section  43  is shown. Here the column  46 B rests on the floor section on a base plate  73 . The ridge beam  46 A is securely affixed and fastened at the top of the column  46 B. This beam  46 A in turn supports the roof section comprised of the EPS  47 , the structural members  46 , the mesh  72  and the cement-like coating  68 . Note well the EPS foam  47  is a two piece assembly as an example and not a limitation. The roof section is similarly configured as the wall sections described above. One also notes that the base plate  73  rests on the pre-sprayed floor  83  and ultimately on the mesh  69  and chassis  50  of the Special Cement-like Coated Mobile Building  31 . 
   In  FIG. 10B , a typical interior wall  44  is shown. Here, the walls are constructed similarly to the exterior and column walls. The EPS foam  47  is vertical and rests inside of a channel or set of angle structures  74  to locate the interior wall  44 . The wall  44  rests on top of the floor system comprised of the wire mesh  64 , the foam  47 , the mesh  72 , and the coating  68 . The interior walls  44  may or may not have the structural members  46 .  FIG. 10C  show an alternative corner system. One skilled in the art appreciates that most wall intersections result in a 90 degree corner inside and out. This is one anticipated configuration. As an alternative embodiment,  FIG. 10C  demonstrates a radiused interior  75  with a foam filled plenum  47  and an augmented angular structural member  71 F. With the spray on cementitious coating  68 , this radius may provide stress reduction to the corner members  54  of the Special Cement-like Coated Mobile Building  31 . 
   In  FIGS. 10D ,  10 E and  10 F, various configurations at key junctions  82  for walls, roofs and floors are shown. These configurations are provided as examples and not limitations to the many different step manners  82  to configure the joints. These intersections demonstrate that the walls, roofs and floors may well be configured in various ways and still be well within the scope and spirit of the Special Cement-like Coated Mobile Building  31 . 
     FIGS. 11A through 11C  are drawings of the model Cement-like Coated Mobile Building from various angles. This model, from various views, shows the Special Cement-like Coated Mobile Building  31  and a front entry view  38  and rear view of the Special Cement-like Coated Mobile Building  31 . 
     FIGS. 12A through 12C  are additional drawings of the model Cement-like Coated Mobile Building  31  with the roof section removed. These drawings permit many of the various components for the Cement-like Coated Mobile Building  31  to be demonstrated. Similarly to the floor plans depicted above in  FIG. 4 , the various features and components are delineated in these drawings. 
   All of the details mentioned here are exemplary and not limiting. Other specific components specific to describing a Special Cementlike Coated Mobile Building and Process to Manufacture  31  may be added as a person having ordinary skill in the field of building devices and methods to manufacture such devices well appreciates. 
   Operation of the Preferred Embodiment 
   The new Special Cement-like Coated Mobile Building device  31  has been described in the above embodiment. Once built, the Special Cement-like Coated Mobile Building device  31  is transported to an area of need, connected to utilities, and is ready for immediate occupancy by persons in need of shelter. The manner of how the device is built is repeated below. One notes well that the description above and the operation described here must be taken together to fully illustrate the concept of the Special Cement-like Coated Mobile Building device  31 . 
   The preferred embodiment described above is essentially comprised of only a few parts as shown in the drawings. This preferred embodiment is comprised of and includes, but is not limited to, a base or chassis  50 , an expanded poly styrene foam  47 , structural members  46  (of various materials and shapes) inside the foam and a cement based material  68  sprayed on the exterior of the foam. The configuration is such that the walls, floor, and roof are rigidly attached to each other yet maintain good flexural strength to resist wind loads and temperature changes. The materials are easily processed to provide many other optional features within the normal course of constructing a mobile home and other buildings. 
   The uses for the mobile home and other devices are many. This same type of Special Cement-like Coated Building  31  could easily be adapted for other uses. The following TABLE C shows some examples and not limitations of this building concept.
