The present invention relates to the construction industry. More specifically, the present invention relates to modular construction of buildings.
Present day construction of a typical building involves extensive time, materials, and attendant costs. This known fact is especially true for residential construction. For a typical structure, an area is surveyed and the land prepared to receive the foundation. A foundation crew builds the forms for the foundation, places reinforcement bar or bar screen mesh within the form, coordinates the delivery of the concrete, and smoothes or otherwise finishes the slab. After several days of curing, the frame of the foundation form is removed and the framing crew begins its efforts. The framing crew is responsible for erecting the framing around the house, including the bottom plates, studs, headers, top plates, joists, rafters, soffits, and other structures to the walls, ceiling and roof. The framing crew also generally places an insulation barrier on at least exterior walls to prepare for an outside finish. A roofing crew then arrives to place a roof, typically shingles or tile, on the framed deck prepared by the framing crew. This process is known as “drying in.” If the exterior surface is to receive a masonry exterior, then a masonry crew then begins the process of laying brick, stone, stucco, or other exterior surfaces. Alternatively, if wood is desired, then the framing crew can apply the boards to the exterior. A finishing crew is responsible for the interior cabinetry, trim, wall coverings, and other internal aspects. At various points along the process, the plumbing, electrical, heating and air conditioning, and other crews are responsible for roughing in, wiring, and installing the various lights, fans, built-in appliances, duct work, outlets, commodes, showers, bathtubs, sinks, and other aspects of a building. The above process can take from start to finish several months and in current prices can be in the range of $75 to $200 per square foot of construction depending on the style and design. The price is increasing as materials become more expensive, especially wood products.
An alternative to the above typical construction is trailer housing. Trailer housing is less expensive and portable, but is generally not of the quality of the above construction. However, trailer construction offers an alternative and in many cases very practical alternative. Typically, the trailer housing is similar to the above construction. However, the foundation is a foundation of steel beams and plates. Similar to the above, the walls are erected, a “skin” of metal or wood is generally placed on the outside of the interior, and interior paneling, plastic or other covering, is placed on the inside with insulation therebetween. The plumbing and electrical specialties are installed at various points of the process. The trailer housing can still be relatively expensive. Further, while the trailer housing is portable, special rigs and expertise must be hired to move the trailer to the site location.
Yet another alternative, at least for large commercial buildings, is tilt wall construction. Generally, the slab foundation is formed as described above. Tilt walls, fabricated offsite, are delivered to the site in relatively large panels weighing several tons. The panels require cranes and other heavy equipment for the erection of the walls with specialized expertise. Further, the tilt wall construction is generally applicable only to exterior walls. Interior walls are still required. Typically, the interior walls will include framing, such as steel framing, and exterior covering to the framing, such as paneling, sheetrock, or other coverings.
Thus, those seeking a new structure are generally required to choose between extensive onsite construction that is expensive and time consuming, purchased trailer housing that can still be expensive, and tilt wall construction that requires specialized equipment and trade skills.
Thus, there remains a need for relatively simple construction system that is efficient in use of time and resources.
The present invention provides a simplified construction module system and method to form a structure by a minimal crew with little specialized trade skills and minimum equipment in a relatively short time period. Relatively lightweight construction modules can be brought to a construction site and linked together to form the structure. In at least one embodiment the present invention includes foundation modules, wall modules, ceiling modules, and roof modules. Further, the modules can be subdivided into specific modules that can be interchanged with other modules, including a door module, window module, and sub-modules. A designer can simply choose between the various modules depending on the size and layout desired. Other building trades such as finishers, plumbing, and electrical can complete the structure as needed. One or more of the modules can be filled after erection on the jobsite with a filler to add strength or stability to the structure.
The disclosure provides a construction module system, comprising: a first module having multiple surfaces around a cavity forming a three dimensional object with a hollow portion, the module having an opening through at least one first module surface, the first module further comprising a protrusion; a second module having multiple surfaces around a cavity forming a three dimensional object with a hollow portion, the module having an opening through at least one second module surface, the second module further comprising a receiver adapted to receive the protrusion to couple the second module with the first module to form an assembled structure; and the first module and the second module being adapted to communicate a pourable material between the opening in the first module surface and the opening in the second module surface when the modules are coupled together.
The disclosure provides a construction module system, comprising: a first foundation module comprising a first series of protrusions, receivers, or combination thereof; a second foundation module comprising a second series of protrusions, receivers, or combination thereof, the second module being adapted to be coupled with the first module to form a foundation of a structure; a wall module comprising a series of protrusions, receivers, or combination thereof adapted to be coupled to the first and the second series of protrusions, the receivers, or combination thereof; wherein the first series of protrusions, the receivers, or a combination thereof is preformed prior to coupling the foundation modules together to coordinate with the second series of protrusions, receivers, or a combination thereof so that a wall formed of one or more of the wall modules can span the first and second foundation modules and be coupled with both of the first and second series of protrusions, receivers, or combination thereof.
The disclosure further provides a method of protecting a building structure, comprising: building a removable at least partial protective shell around the building structure by coupling a plurality of removable modules together, the modules comprising multiple surfaces around a cavity forming a three dimensional object with a hollow portion and a series of preformed protrusions, receivers, or combination thereof to allow the coupling.
A more particular description of the invention, briefly summarized above, can be realized by reference to the embodiments thereof that are illustrated in the appended drawings and described herein. However, it is to be noted that the appended drawings illustrate only some embodiments of the invention. Therefore, the drawings are not to be considered limiting of its scope, for the invention may admit to other equally effective embodiments. Like elements will be numbered consistently throughout the figures.
In the description that follows, like elements are marked throughout the specifications and drawings with the same reference numerals, respectively. The drawing figures are not to scale. The elements are generally shown in schematic form in the interest of clarity and conciseness.
The size, shape, and layout of the modules can vary. If necessary, the modules can be coded in some fashion, such as by color or numerically, to identity its respective position in the overall structure to assist in assembly. A software program can be used to allow a designer or other persons such as the end user assistance in selecting and laying out an intended structure. Further, the design or layout can include openings, modules, and other places for heating, venting, and cooling in the floor, walls, or ceilings.
The foundation 4 can include one or more foundation modules 6. A foundation module 6 can be coupled joined at a foundation seam 8 to another foundation module. The foundation module can vary as described in more detail in reference to
Similarly, the wall 10 can include one or more wall modules. For example, the wall 10 can include a wall end module 12, a door module 14, a window module 16, and other modules. One or more of the modules can have an opening such as a door opening 15 in the door module 14 and a window opening 17 in the window module 16, generally collectively referred to as “pass through openings” herein. Advantageously, the modules are generally interchangeable so that the position of the respective modules, such as the door module, can be interchanged with other modules around the structure.
Further, the wall 10 with its respective modules (or other portions of the structure's modules) can include sub-modules. For example, a window sub end module 18 can be smaller than a regular sized wall module. Advantageously, the sub-modules can be incrementally sized, such as one-half or one-third, of a wall module to help maintain interchangeability between the various modules, if desired. Further, a sub-module can assist in staggering a seam of a wall module, such as seam 9, at a different location than a foundation seam 8. This staggering, similar to laying brick on a wall, can help provide structural integrity. The wall 10 can also include one or more wall universal modules 20 and other sub end modules 22 that may or may not have various openings therethrough.
The modules of the wall 10 or other portions of the structure can further include a first surface layer 24, which can be an outer layer. The first surface layer may be coupled to the wall 10 or other portion, including integrally formed thereon. The first surface layer 24 can be formed in a decorative fashion, such as representing brick, stone, wood siding, stucco, or other attractive appearances.
The roof 30 can be formed from one or more roof modules. For example, a roof end module 32 can be disposed at appropriate locations on the roof, such as at an end. The roof end module 32 can be coupled to a roof universal module 34. Further, the roof 30 can include a roof opening module 36. The roof opening module 36 can include one or more openings 37. The opening 37 can provide a preformed opening for a vent through the roof, piping, or even a chimney.
An end of the roof may need enclosing relative to the wall 10. To provide a transition, the construction module system 2 can include a wall-to-roof transition portion 40. The transition portion 40 can include a tapered module 42. The tapered module 42 can form a transition between the generally horizontal level surface of the wall 10 to the angular portion of the roof 30. A transition universal module 46 can be coupled to the tapered module 42 to fill in additional space. The tapered module 42 can be disposed adjacent the universal module 46 to transition to the other side of the roof 30, as appropriate. The number of tapered modules 42 and universal modules 46 can vary depending upon the size of the construction module system 2 and the number of foundation and wall modules used. A top cap module 44 can complete the transition between the wall 10 and the roof 30. For efficiency, the roof 30 can have a constant angle with respect to the wall 10 to assist in uniformly producing and erecting the transition portion 40, although the number of pieces may vary depending upon the width of the structure being assembled.
Further, the wall, roof, and/or foundation modules may be hollow in that the surfaces of the modules may form a cavity therein. For example, the foundation 4 may have a hollow portion 52 and the wall 10 may have a hollow portion 26. In general, it will be advantageous to fill with a pourable the hollow portions of at least some of the modules with a substance to add structural integrity, insulation, or other desired effects to the modules. In some embodiments, the filling however may be unnecessary or undesirable. If filling is used, then one or more openings, such as opening 60 into wall 10 and/or opening 64 in the foundation 4, may be formed through which filler can be placed in the modules. In at least one embodiment, the filler can be hardenable fluid such as concrete, a foaming insulation, a moldable product, or other structural materials. In another embodiment, the filler can be a pourable sand or other granulated substance that can be hardenable or can remain in loose fashion. In yet another embodiment, the filler can be a liquid or gel that again can be hardenable or stay in a liquid or gel form. For ease of assembly, it is believed that the modules will generally be erected first and then the filler placed therein. However, in some embodiments, it may be advantageous to place the filler in the module prior to modular placement.
The schematic also illustrates one or more protrusions 48 coupled to the wall modules that can engage the foundation 4 as described in reference to
If the wall module is sufficiently high, then additional wall modules may be used to complete the height of the desired wall 10. Therefore, additional receivers 54, similar to the receiver 54 in the foundation described in reference to
Further, the modules may include a cross member 80. The cross member 80 can assist in supporting the module across the hollow portion 26 or other hollow portions formed in the module by providing structural integrity across the void. Further, a pair of cross members 80 can form an opening 82 therebetween. The opening 82 can be filled with filler, as has been described above. Alternatively, the opening 82 can provide a passageway for plumbing, electrical, vents, and other utility and appliance connections. For example, an opening 88 can be formed in a portion of the module through which plumbing, such as piping or electrical conduit or wiring, can enter the space adjacent the module. The cross members on either side of the opening 82 can seal adjacent hollow portions so that the adjacent hollow portions can still be filled at least partially with a filler. The opening 88 can provide also a mounting surface for various utility service outlets such as electrical outlets, water faucets, drain lines, and other utilitarian functions that need access through a wall, ceiling, roof, or even a foundation.
The modules of the foundation 4 can be coupled to each other by a similar receiver/protrusion relationship. For example, one edge of a module can include a protrusion 91 and a receiver 93. Another edge can include a protrusion 90 and a receiver 92. The relative spacing and placement of the protrusions and receivers can allow adjacent foundation modules to be coupled to each other. Further, an opening 94 can be formed through a protrusion and/or receiver to allow a connector 96 to be inserted through the receiver and/or protrusion when an adjacent module is coupled thereto to help secure the coupling between the adjacent modules. In some embodiments, it may be desirable to offset the engagement axis of the opening 94 on one side of the module from an engagement axis on another side of the module. In such instances, the engagement axis could be at a different elevation. Such an offset would need coordination with an adjacent module to ensure proper coupling, as necessary.
The aforementioned modules are exemplary only and can be arranged in various fashion to accommodate the design of the structure. For example, kitchen modules can be placed at various locations and various interior and exterior walls coupled thereto, as may be desired or planned. The “T” module 102 can be used at interior portions such as adjacent to the cross module 116 to define a series of supports for interior walls that form a larger room overlapping two or more modules. Similarly, “T” modules and/or “L” modules can be coupled to the kitchen modules 112 to accommodate larger rooms that may overlap two or more modules. Further, such positioning with the respective receivers can be used to create intermediate walls, counters, and other surfaces.
As described above, the various modules can include receivers (or protrusions) as may be suitable for the particular module. It is believed that a representative variety of foundation modules, wall modules, roof modules, and ceiling modules can provide sufficient customization for many structural needs and desires of the consumer.
The modules can include one or more series of coupling elements, such as the receivers described above. For example, the universal module 100 can include a first series 118, a second series 119, a third series 120, and a fourth series 121. In the arrangement illustrated (and only for illustrative purposes) the universal module 100 can be placed at a corner so that the first series 118 and the fourth series 121 can be used to support an external wall. One or more of the interior series 119, 120 can be used to support an internal wall if appropriate. Similarly, the “T” module 102 can include a first series 123 and a second series 124. In the arrangement illustrated in
Similar combinations can be made with the kitchen module 112 in combination with its series 132 and adjacent series 136 and 138 of the adjacent module 114, and series 134 of an adjacent module on another edge of the kitchen module 112 as shown. For example, the main kitchen could be formed on the kitchen module 112 and extended to series 134. Series 136 and 138 could form a pantry with a suitable interior wall having a door opening. A second door opening in an interior wall could be mounted on one of the series in the cross module 116 to allow ingress and egress into the kitchen area.
The bathroom module 106 can include one or more openings in the module. For example, an opening 126 can either be a partial opening that does not substantially go through the entire thickness of the module 106 or can be an opening that goes fully therethrough. The opening 126 can provide access for other building trades, such as a plumber, to lay drainage, sewage, and water lines therethrough. The opening can afterwards be sealed with some substance, such as concrete, poured into the opening, so that appliances or fixtures can be mounted thereon, such as commodes, shower stalls, and so forth. Opening 128 can be a larger opening that might accommodate a bathtub or other larger opening and through which various utility lines may be placed. In a similar fashion, an opening 130 in the kitchen module 112 can be used to place drainage lines, water lines, electrical and other utility connections for sinks, waste disposals, and other appliances.
Thus, a building structure can be completed by the proper selection and then assembly of the modules in a relatively short and standardized fashion. In general, it is believed that the foundation modules will include receivers below the top surface of the foundation module. Thus, any receivers that are not used may be filled with a filler, such as a hardenable material like concrete, to facilitate walking over the surfaces. Still further, other form of coverings can be mounted to the foundation surfaces, such as carpet, vinyl, and other floor coverings.
The upper surface of the foundation 4a can be formed with receivers 54 and interior receivers 54a as may be appropriate to the particular layout. The foundation 4a could be used to support the wall modules, ceiling modules, roof modules, and other modules described above.
The upper portion of the interior walls can contain one or more interior recesses 54a and support surfaces 68a similar to the receiver 54 and support surface 68, described in reference to
The construction module system 2 can also be used to build a structure 3 as a protective shell around another structure 164. The protective shell can includes one or more walls, a roof, a foundation, or a combination thereof. In at least one embodiment, a roof can be formed over the structure 164 that can include roof modules as described above. Alternatively, the roof can be a conventional roof with metal, asphalt shingles, tiles, and so forth. The walls are generally formed at least partially with a plurality of wall modules 12 described above. The wall modules can be coupled together in sections as appropriate.
The walls can be moved between a first position and a second position, where one of the positions is more protective than the other position. In at least one embodiment, the wall modules can be rotatably coupled together in a vertical fashion that can be raised and lowered as needed for protection. A plurality of columns 168 can assist in supporting and guiding the wall modules. For example and without limitation, the column 168 can form a guide channel 172 in which a guide 174 can move, where the guide 174 is coupled to the wall module 12. The guide 170 can be a wheel, post, or other guiding element. One or more sections can be raised and lowered when there are multiple sections coupled together. Alternatively, the wall modules can simply be removed and reassembled as necessary and thus a guide 174 may not be particularly useful.
The modules can be at least partially filled with the pourable material described above on site, such as when the modules are in a protective position to the protected structure. At least a portion of the pourable material can be emptied from the modules when the protective need ends to facilitate easier removal or movement of the modules.
