     BACKGROUND OF THE INVENTION 
     Field of the Invention 
     The inventions herein relate to structures, such as dwellings and other buildings for residential occupancy, commercial occupancy and/or material storage, and to components for such structures. 
     Description of the Related Art 
     In the field of residential housing, the traditional technique for building homes is referred to as “stick-built” construction, where a builder constructs housing at the intended location using in substantial part raw materials such as wooden boards, plywood panels, and steel columns. The materials are assembled piece by piece over a previously prepared portion of ground, for example, a poured concrete slab or a poured concrete or cinder block foundation. 
     There have been a variety of efforts to depart from the conventional construction techniques used to create dwellings, as well as commercial spaces and like, in an effort to reduce costs. In this regard, significant advancements in the construction of dwellings and commercial space have been made by the current inventors, as exemplified by their patent documents, including U.S. Pat. Nos. 8,474,194, 8,733,029, 10,688,906, 10,829,029, 10,926,689 and 11,220,816. In one aspect, these patents pertain to fabricating wall, floor and roof components in a factory that are folded together into a compact shipping module, and which are then transported to the intended location and unfolded to yield a fully formed structure. 
     SUMMARY OF THE INVENTION 
     The present inventions describe advancements in the design of appurtenances for building structures, particularly for the wall components of such structures. 
     In a first aspect, the present inventions are directed to a toe screw housing for securing abutting enclosure components together. The toe screw housing comprises a bearing plate with a planar interior face, a planar exterior face and a beveled upper edge beveled at a non-perpendicular first angle relative to the exterior face. There is provided a toe screw well, joined to and extending away from the interior face of the bearing plate, which includes a fastener shelf, and there is provided a toe screw support that is joined to the interior face of the toe screw housing, and which is also joined to and extending away from the fastener shelf. The toe screw support distal from the fastener shelf includes a planar support surface oriented perpendicular to the interior face. A fastener bore passes through the fastener shelf, the toe screw support and the support surface, and is inclined at a non-perpendicular second angle relative to the interior face of the bearing plate. 
     In a second aspect, the present inventions are directed to a baseboard for masking a toe screw bearing plate that has a beveled upper edge. The baseboard comprises a planar elongate member having an elongate interior face, an elongate top edge and an elongate bottom edge. An elongate hook ledge is joined to the top edge of the base board to form a wedge-shaped angled slot that is oriented to be open in the direction of the bottom edge, with the wedge-shaped angled slot configured to be positioned over the beveled upper edge of the bearing plate. There is provided an elongate linear first step positioned on the interior face below the angled slot to form an elongate first recess on the interior face configured to receive the toe screw bearing plate, and there is provided an elongate second step positioned on the interior face below the elongate first step to form an elongate second recess on the interior face. 
     These and other aspects of the present inventions are described in the drawings annexed hereto, and in the description of the preferred embodiments and claims set forth below.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     An embodiment of the foldable, transportable structure  150  in which the inventions disclosed herein can be implemented is depicted in  FIGS. 1 through 5 . When fully unfolded, as exemplified by  FIG. 1 , structure  150  has a rectangular shape made of three types of generally planar and rectangular enclosure components  155 , the three types of enclosure components  155  consisting of a wall component  200 , a floor component  300 , and a roof component  400 . As shown in  FIGS. 1 and 2 , the perimeter of structure  150  is defined by first longitudinal edge  106 , first transverse edge  108 , second longitudinal edge  116  and second transverse edge  110 . For convenience, a direction parallel to first longitudinal edge  106  and second longitudinal edge  116  may be referred to as the “longitudinal” direction, a direction parallel to first transverse edge  108  and second transverse edge  110  may be referred to as the “transverse” direction; and a direction parallel to the vertical direction in  FIG. 1  may be referred to as the “vertical” direction. Structure  150  as shown has one floor component  300 , one roof component  400  and four wall components  200 ; although it should be understood that the present inventions are applicable to structures having other configurations as well. 
     Enclosure components  155  (wall component  200 , floor component  300  and roof component  400 ) can be fabricated and dimensioned as described herein and positioned together to form a shipping module  100 , shown end-on in  FIG. 3 . The enclosure components  155  are dimensioned so that the shipping module  100  is within U.S. federal highway dimensional restrictions. As a result, shipping module  100  can be transported over a limited access highway more easily, and with appropriate trailering equipment, transported without the need for oversize permits. Thus, the basic components of structure  150  can be manufactured in a factory, positioned together to form the shipping module  100 , and the modules  100  can be transported to the desired site for the structure, where they can be readily assembled, as described herein. 
     Enclosure Component ( 155 ): General Description 
     The enclosure components  155  of the present invention include a number of shared design features that are described below. 
     A. Laminate Structure Design 
     Enclosure components  155  can be fabricated using a multi-layered, laminate design. A particular laminate design that can be used to fabricate enclosure components  155  comprises a first structural layer  210 , a foam panel layer  213 , a second structural layer  215  and a protective layer  218 , as shown in  FIG. 7  and described further below. 
     In particular, first structural layer  210  is provided in the embodiment of enclosure component  155  that is depicted in  FIG. 7 . First structural layer  210  in the embodiment shown comprises a sheet metal layer  205 , which can be for example galvanized steel or aluminum. Sheet metal layer  205  is made from a plurality of generally planar rectangular metal sheets  206  positioned adjacent to each other to generally cover the full area of the intended enclosure component  155 . 
     Referring again to  FIG. 7 , there is next provided in the depicted embodiment of enclosure component  155  a foam panel layer  213 , comprising a plurality of generally planar rectangular foam panels  214  collectively presenting a first face  211  and a second opposing face  212 . Foam panels  214  are made for example of expanded polystyrene (EPS) foam. A number of these foam panels  214  are positioned adjacent to each other and superposed first face-down on first structural layer  210  to generally cover the full area of the intended enclosure component  155 . The foam panels  214  of foam panel layer  213  preferably are fastened to first structural layer  210  using a suitable adhesive, preferably a polyurethane based construction adhesive. 
     In the embodiment of the enclosure component  155  depicted in  FIG. 7 , there is next provided a second structural layer  215 , having a first face that is positioned on the second opposing face  212  of foam panels  214  (the face distal from first structural layer  210 ), and also having a second opposing face. Second structural layer  215  in the embodiment shown comprises a sheet metal layer  216 , which can be for example galvanized steel or aluminum. Sheet metal layer  216  is made from a plurality of generally planar rectangular metal sheets  217  positioned adjacent to each other and superposed first face-down on the second opposing face of foam panel layer  213  to generally cover the full area of the intended enclosure component  155 . The metal sheets  217  of second structural layer  215  preferably are fastened to foam panel layer  213  using a suitable adhesive, preferably a polyurethane based construction adhesive. 
     In the embodiment of the enclosure component  155  depicted in  FIG. 7 , there is optionally next provided a protective layer  218 , having a first face that is positioned on the second opposing face of second structural layer  215  (the face distal from foam panel layer  213 ), and also having a second opposing face. Optional protective layer  218  in the embodiment shown comprises a plurality of rectangular structural building panels  219  principally comprising an inorganic composition of relatively high strength, such as magnesium oxide (MgO). The structural building panels  219  are positioned adjacent to each other and superposed first face-down on the second opposing face of second structural layer  215  to generally cover the full area of the intended enclosure component  155 . The building panels  219  of protective layer  218  preferably are fastened to second structural layer  215  using a suitable adhesive, preferably a polyurethane based construction adhesive. Protective layer  218  can be used if desired to impart a degree of fire resistance to the enclosure component  155 , as well as to provide a pleasing texture and/or feel. 
     Other embodiments of multi-layered, laminate designs that can be used to fabricate the enclosure components  155  of the present invention, are described in U.S. Nonprovisional patent application Ser. No. 16/786,130, entitled “Foldable Building Structures with Utility Channels and Laminate Enclosures,” filed on Feb. 10, 2020 and now issued as U.S. Pat. No. 11,118,344. The contents of that U.S. Nonprovisional patent application Ser. No. 16/786,130, entitled “Foldable Building Structures with Utility Channels and Laminate Enclosures” and filed on Feb. 10, 2020 are incorporated by reference as if fully set forth herein, particularly including the multi-layered, laminate designs described for example at  0034-57 and depicted in FIGS. 4A-4D thereof. 
     B. Enclosure Component Exterior Edge Reinforcement 
     The exterior edges of each enclosure component  155  (i.e., the edges that define the perimeter of enclosure component  155 ) can be provided with exterior edge reinforcement, as desired. Exterior edge reinforcement generally comprises an elongate, rigid member which can protect foam panel material that would otherwise be exposed at the exterior edges of enclosure components  155 . Exterior edge reinforcement can be fabricated from one or more of laminated strand lumber board, wooden board, C-channel extruded aluminum or steel, or the like, and is generally secured to the exterior edges of enclosure component  155  with fasteners, such as screw or nail fasteners, and/or adhesive. 
     C. Enclosure Component Partitioning 
     Enclosure components  155  in certain instances are partitioned into enclosure component portions to facilitate forming a compact shipping module  100 . In those instances where an enclosure component  155  is partitioned into enclosure component portions, any exterior edge reinforcement on the exterior edges defining the perimeter of the enclosure component is segmented as necessary between or among the portions. 
     The enclosure component portions can be joined by hinge structures or mechanisms to permit the enclosure component portions to be “folded” and thereby contribute to forming a compact shipping module  100 . 
     D. Enclosure Component Interior Edge Reinforcement 
     An enclosure component  155  partitioned into enclosure component portions will have interior edges. There will be two adjacent interior edges for each adjacent pair of enclosure component portions. Such interior edges can be provided with interior edge reinforcement. Similar to exterior edge reinforcement, such interior edge reinforcement generally comprises an elongate, rigid member which can protect foam panel material that would otherwise be exposed at the interior edges of enclosure components  155 . Interior edge reinforcement can be fabricated from one or more of laminated strand lumber board, wooden board, C-channel extruded aluminum or steel, or the like, and is generally secured to the interior edges of enclosure component  155  with fasteners, such as screw or nail fasteners, and/or adhesive. 
     E. Enclosure Component Load Transfer 
     In the case of enclosure components  155 , it is necessary to transfer the loads imposed on their surfaces to their exterior edges, where those loads can be transferred either to or through adjoining walls, or to the building foundation. For enclosure components  155  that are horizontally oriented when in use (floor component  300  and roof component  400 ), such loads include the weight of equipment, furniture and people borne by their surfaces, as well as vertical seismic loads. For enclosure components that are vertically oriented when in use (wall component  200 ), such loads include those arising from meteorological conditions (hurricanes, tornadoes, etc.) and human action (vehicle and other object impacts). 
     For this purpose, multi-layered, laminate designs as shown in  FIG. 7  will function to transfer the loads described above. To add additional load transfer capability, structural members, such as beams and/or joists, can be utilized within the perimeter of the enclosure components  155 , as is deemed appropriate to the specific design of structure  150  and the particular enclosure component  155 , to assist in the transfer of loads to the exterior edges. Particular embodiments of such structural members, which also incorporate hinge structures, are described in U.S. Nonprovisional patent application Ser. No. 17/527,520 entitled “Folding Beam Systems”, filed Nov. 16, 2021 and having the same inventors as this disclosure. The contents of that U.S. Nonprovisional patent application Ser. No. 17/527,520 entitled “Folding Beam Systems”, filed Nov. 16, 2021 and having the same inventors as this disclosure, is incorporated by reference as if fully set forth herein, particularly the description of the hinged load transfer components set forth for example in  0074-0089 and 0104-0126 and in FIGS. 8A-13E and 15A-24A thereof, as well as the description of the associated end hinge assemblies set forth for example in  0090-0093 and 0127-0132 and in FIGS. 14A-14B, 24B and 25A-25D thereof. 
     F. Enclosure Component Sealing Systems 
     Structure  150  comprises a number of wall, floor and roof components with abutting or exposed exterior edges, as well as a number of partitioned wall, floor and roof components with interior edges. In this regard, sealing structures can be utilized, with the objective to limit or prevent the ingress of rain water, noise and outside air across these exterior and interior edges into the interior of structure  150 . 
     Particular sealing structures for accomplishing the foregoing objective are described in PCT Patent Application No. PCT/US21/56415, entitled “Enclosure Component Sealing Systems,” filed on Oct. 25, 2021 and having the same inventors as the present application. The contents of that PCT Patent Application No. PCT/US21/56415, entitled “Enclosure Component Sealing Systems,” filed on Oct. 25, 2021 and having the same inventors as this disclosure, are incorporated by reference as if fully set forth herein, particularly including the sealing systems described for example at  0080-0167 and depicted in FIGS. 9-20 thereof, and also including the exemplary placements for such sealing systems described in  0168-0174 and depicted in FIGS. 8A-8B thereof. 
     Further design details of wall component  200 , floor component  300 , and roof component  400  are provided in the sections following. 
     Wall Component ( 200 ) 
     Typically, structure  150  will utilize four wall components  200 , with each wall component  200  corresponding to an entire wall of structure  150 . 
     A. General Description 
     Wall component  200  has a generally rectangular perimeter. As shown in  FIG. 1 , wall components  200  have plural apertures, specifically a door aperture  202 , which has a door frame and door assembly, and plural window apertures  204 , each of which has a window frame and a window assembly. The height and length of wall components  200  can vary in accordance with design preference, subject as desired to the dimensional restrictions applicable to transport, described above. In this disclosure, structure  150  is fashioned with all sides of equal length; accordingly, its first and second longitudinal edges  106  and  116 , and its first and second transverse edges  108  and  110 , are all of equal length. It should be understood however, that the inventions described herein are applicable to structures having other dimensions, such as where two opposing wall components  200  are longer than the other two opposing wall components  200 . 
     As indicated above, wall components  200  of the present inventions can utilize a multi-layered, laminate design. In the embodiment depicted in  FIGS. 1 through 6 , wall component  200  utilizes the multi-layered, laminate design shown in  FIG. 7  employing these particular elements: sheet metal layer  205  of first structural layer  210  is 24 gauge galvanized steel approximately 0.022-0.028 inch thick, the foam panels  214  of foam panel layer  213  are EPS foam approximately 5.68 inches thick, the sheet metal layer  216  of second structural layer  215  is 24 gauge galvanized steel approximately 0.022-0.028 inch thick, and the building panels  219  of protective layer  218  are MgO board approximately 0.25 inch (6 mm) thick. 
     The perimeter of each wall component  200  is generally provided with exterior edge reinforcement. As exemplified by wall component  200  shown in  FIG. 6 , the exterior edge reinforcement for wall component  200  is a floor plate  220  along the bottom horizontal edge, a ceiling plate  240  along the top horizontal edge and two end pieces  270  respectively fastened at each vertical edge of wall component  200 . In the case of a wall component  200 , exterior edge reinforcement provides regions for fastening like regions of abutting wall components  200 , roof component  400  and floor component  300 , in addition to protecting the exterior edges of foam panel material. In the embodiment shown in  FIGS. 1 through 6 , the exterior edge reinforcement for wall component  200  provided by floor plate  220 , ceiling plate  240 , and end pieces  270  is fabricated from laminated strand lumber board 5.625″ deep and 1.5″ thick. 
     B. Partitioned Wall Components 
     Referring to  FIG. 2 , structure  150  has two opposing wall components  200 , where one of the two opposing wall components  200  comprises first wall portion  200   s - 1  and second wall portion  200   s - 2 , and the other of the two opposing wall components  200  comprises third wall portion  200   s - 3  and fourth wall portion  200   s - 4 . Each of wall portions  200   s - 1 ,  200   s - 2 ,  200   s - 3  and  200   s - 4  has a generally rectangular planar structure. As shown in  FIG. 2 , the interior vertical edge  192 - 1  of wall portion  200   s - 1  is proximate to a respective interior vertical edge  192 - 2  of wall portion  200   s - 2 , and the interior vertical edge  194 - 3  of wall portion  200   s - 3  is proximate a respective interior vertical wall edge  194 - 4  of wall portion  200   s - 4 . Interior edge reinforcement can be provided at any one or more of vertical edges  192 - 1 ,  192 - 2 ,  194 - 3  and  194 - 4 . In the embodiment shown in  FIGS. 1 through 6 , the interior edge reinforcement provided at vertical edges  192 - 1 ,  192 - 2 ,  194 - 3  and  194 - 4  is fabricated from laminated strand lumber board 5.625″ deep and 1.5″ thick. 
     Referring again to  FIG. 2 , first wall portion  200   s - 1  is fixed in position on floor portion  300   a  proximate to first transverse edge  108 , and third wall portion  200   s - 3  is fixed in position on floor portion  300   a,  opposite first wall portion  200   s - 1  and proximate to second transverse edge  110 . First wall portion  200   s - 1  is joined to second wall portion  200   s - 2  with a hinge structure that permits wall portion  200   s - 2  to pivot about vertical axis  192  between a folded position and an unfolded position, and third wall portion  200   s - 3  is joined to fourth wall portion  200   s - 4  with a hinge structure to permit fourth wall portion  200   s - 4  to pivot about vertical axis  194  between a folded position and an unfolded position. 
     Notably, first wall portion  200   s - 1  is longer than third wall portion  200   s - 3  by a distance approximately equal to the thickness of wall component  200 , and second wall portion  200   s - 2  is shorter than fourth wall portion  200   s - 4  by a distance approximately equal to the thickness of wall component  200 . Furthermore, wall portion  200   s - 1  and wall portion  200   s - 3  are each shorter in length (the dimension in the transverse direction) than the dimension of floor portion  300   a  in the transverse direction. Dimensioning the lengths of wall portions  200   s - 1 ,  200   s - 2 ,  200   s - 3  and  200   s - 4  in this manner permits wall portions  200   s - 2  and  200   s - 4  to nest against each other in an overlapping relationship when in an inwardly folded position. In this regard,  FIG. 2  depicts wall portions  200   s - 2  and  200   s - 4  both in their unfolded positions, where they are labelled  200   s - 2   u  and  200   s   4 - u  respectively, and  FIG. 2  also depicts wall portions  200   s - 2  and  200   s - 4  both in their inwardly folded positions, where they are labelled  200   s - 2   f  and  200   s   4 - f  respectively. When wall portions  200   s - 2  and  200   s - 4  are in their inwardly folded positions ( 200   s - 2   f  and  200   s - 4   f ), they facilitate forming a compact shipping module. When wall portion  200   s - 2  is in its unfolded position ( 200   s - 2   u ), it forms with wall portion  200   s - 1  a wall component  200  proximate first transverse edge  108 , and when wall portion  200   s - 4  is in its unfolded position ( 200   s - 4   u ), it forms with wall portion  200   s - 3  a wall component  200  proximate second transverse edge  110 . 
     The hinge structures referenced for securing first wall portion  200   s - 1  to second wall portion  200   s - 2 , and third wall portion  200   s - 3  to fourth wall portion  200   s - 4 , can be surface mounted or recessed, and of a temporary or permanent nature. The provision of interior edge reinforcement, as described above, can provide a region for securing hinge structures. Suitable hinge structures can be fabricated for example of ferrous or non-ferrous metal, plastic or leather material. 
     C. Unpartitioned Wall Components 
     As compared to the two wall components  200  proximate first and second transverse edges  108  and  110 , which are partitioned into wall portions, the remaining two wall components  200  proximate first and second longitudinal edges  106  and  116  do not comprise plural wall portions, but rather each is a single piece structure. However, one of these wall components  200 , which is sometimes denominated  200 P in this disclosure, and which is located on floor portion  300   b  proximate first longitudinal edge  106 , is pivotally secured to floor portion  300   b  to permit wall component  200 P to pivot about horizontal axis  105  shown in  FIG. 3  from a folded position to an unfolded position. Pivotally securing wall component  200 P also facilitates forming a compact shipping module  100 . The remaining wall component  200 , sometimes denominated  200 R in this disclosure, is rigidly secured on floor portion  300   a  proximate second longitudinal edge  116  and abutting the vertical edges of first wall portion  200   s - 1  and third wall portion  200   s - 3  proximate to second longitudinal edge  116 , as shown in  FIG. 2 . 
     The hinge structures described above, for securing wall component  200 P to floor portion  300   b,  can be surface mounted or recessed, and of a temporary or permanent nature. The provision of exterior edge reinforcement, as described above, can provide a region for securing hinge structures. Suitable hinge structures can be fabricated for example of metal, plastic, leather, ferrous or non-ferrous material. 
     D. Wall Component Appurtenances 
     Certain appurtenances can be fitted to wall components  200  to facilitate fastening them to floor component  300  (described below), as well as to improve the interior appearance and speed fabrication. 
     As a first appurtenance that can be fitted to wall components  200 ,  FIGS. 8A-8C  depict a toe screw housing  288 , whose principal components comprise a bearing plate  292 , a toe screw well  289  and a toe screw support  221 . Bearing plate  292  is a planar plate of a select thickness having a rectangular perimeter, and includes an exterior face  293 , an opposed interior face  294  and a top, bevel edge  297 . Toe screw well  289  comprises a semi-cylindrical wall  298  having an axial centerline  198 , shown in  FIG. 8C , which is oriented at an angle (pi from a line normal to the interior face  294  of bearing plate  292 . Angle φ 1  can be in the range of forty-five) (45°) to seventy (70°) degrees, such as sixty (60°) degrees. The exterior face  293  of bearing plate  292  defines an aperture that renders the interior volume of toe screw well  289  accessible from the exterior face side of toe screw well  289 . 
     An upper portion of semi-cylindrical wall  298  is angularly sectioned, for example at an angle of ninety degrees (90°) minus φ 1 , relative to axial centerline  198 , for example in the range of forty-five (45°) to twenty (20°) degrees, such as thirty (30°) degrees, with the upper portion so sectioned joined to interior face  294 . A lower portion of semi-cylindrical wall  298  is further sectioned parallel to axial centerline  198 , with each of the resultant two axially-oriented edges joined to a respective triangular gusset  299 . The two gussets  229  are spatially opposed and joined to the interior face  294  of bearing plate  292 . Toe screw well  289  also includes a fastener shelf  239 , visible in  FIG. 8A , which is joined to semi-cylindrical wall  298  and each of the two gussets  299 . The interior volume of toe screw well  289 , which is defined by fastener shelf  239 , gussets  299  and semi-cylindrical wall  298 , forms a recess within toe screw well  289  for receiving a fastener head. Fastener shelf  239  has a planar upper face that is perpendicularly oriented to the axial centerline  198  of semi-cylindrical surface  298 , and a planar opposed lower face that is perpendicularly oriented to the axial centerline  198  of semi-cylindrical surface  298 . It should be noted that the upper face of fastener shelf  239  will correspondingly be oriented at angle (pi relative to interior face  294  and exterior face  293 . 
     The lower face of fastener shelf  239  is joined to a toe screw support  221 . Toe screw support  221  comprises a semi-cylindrical solid  222  and a triangular wedge  223 . Semi-cylindrical solid  222  has an axial centerline  197 , shown in  FIG. 8C , which is oriented at an angle φ 2  from a line normal to the interior face  294  of bearing plate  292 . Angle φ 2  can be in the range of forty-five (45°) to seventy (70°) degrees, such as sixty (60°) degrees, and preferably φ 1  equals φ 2 . Centerlines  197  and  198  can be, but need not be, co-linear. The upper portion of semi-cylindrical solid  222  is sectioned normal to axial centerline  197 , with the sectioned portion joined to the lower face of fastener shelf  239 , and is further sectioned parallel to axial centerline  197  and joined to triangular wedge  223 . In turn, the upper surface of wedge  223  is joined to the lower face of fastener shelf  239 , and wedge  223  is further joined at its narrow end to the interior face  294  of bearing plate  292 . The diameter of semi-cylindrical solid  222  is less than the diameter of semi-cylindrical wall  298 , in the embodiment shown in  FIGS. 8A-8C . 
     Toe screw support  221  also includes a support surface  224  defined by the lower surfaces of semi-cylindrical solid  222  and wedge  223 . Support surface  224  is perpendicularly oriented to the interior face  294  of bearing plate  292 . A groove  199  is cut into the planar lower surface of support surface  224 . Groove  199  is oriented parallel to the interior face  294  of bearing plate  292 , and, in the embodiment shown in the figures, is spaced from interior face  294  a distance approximately equal to the thickness of protective layer  218 . 
     A fastener bore  225  passes through fastener shelf  239  and toe screw support  221 , with an exit orifice in support surface  224 , thereby forming a passage through toe screw support  221  for a fastener, the head of which can be positioned against the upper face of fastener shelf  239 . Preferably, the axial centerline of fastener bore  225  is co-linear with the axial centerline  197  of semi-cylindrical wall  222 , so that the axial centerline of fastener bore  225  is not perpendicular to the exterior face  293  of bearing plate  292 , but rather is oriented at angle φ 2  from a line normal to the exterior face  293  of bearing plate  292 . 
     Bevel edge  297  of toe screw housing  288  forms an angle φ 3  with exterior face  293  to provide a sloped bevel surface between the end of bevel edge  297  and interior face  294  of bearing plate  292 . Accordingly, angle φ 3  is not perpendicular to the exterior face  293  of bearing plate  292 , but rather is an acute angle, such as forty-five degrees (45°) or less, and in particular twenty degrees (20°). 
     As a second appurtenance that can be fitted to wall components  200 ,  FIGS. 9A-9C  depict an interior baseboard  140 . Interior baseboard  140  is a planar elongate member with a planar elongate exterior face  141 , a planar elongate interior face  142 , an elongate top edge  143  and an elongate bottom edge  144 . An elongate hook ledge  145  is joined along the top edge  143  of interior baseboard  140  and forms a downward facing wedge-shaped angled slot  146  that has an interior angle φ 4 , shown in  FIG. 9C , which is preferably the same as angle φ 3  of bevel edge  297 , or nearly so. Interior face  142  has an elongate linear first step  147  positioned below angled slot  146 , so as to define an elongate bearing plate recess  148  between angled slot  146  and first step  147  sufficiently wide to receive bearing plate  292 . Positioned below first step  147 , interior face  142  has an elongate linear second step  137  that extends a distance from bottom edge  144 , so as to define a fastening recess  138  between first step  147  and second step  138 . 
     For wall components  200  utilizing the laminate design shown in  FIG. 7 , a plurality of toe screw housings  288  can be fastened at space-apart intervals in proximity to the bottom of the wall components  200 , as shown in  FIG. 10C . As shown in  FIG. 10A , each toe screw housing  288  is positioned so that the support surface  224  of its toe screw support  221  rests upon the floor plate  220  of the wall component  200 . Select portions of the foam panel layer  213 , sheet metal layer  216  and protective layer  218  are removed to provide a space to receive the toe screw well  289  and toe screw support  221  of the toe screw housing  288 , and so that the interior face  294  of bearing plate  292  of the toe screw housing  288  lies against protective layer  218 . As described above, the distance from groove  199  to interior face  294  of bearing plate  292  is approximately equal to the thickness of protective layer  218 . When so dimensioned, groove  199  can engage the edge of sheet metal layer  216  immediately below the removed portion thereof, as shown in  FIG. 10A . 
     Plural toe screw housings  288  can be utilized to fasten both partitioned and unpartitioned wall components  200  to floor component  300  (described below). For example, referring to  FIGS. 10B and 10C , toe screw housings  288  are shown being utilized in connection with both wall portion  200   s - 4  and wall component  200 P. Following their unfolding (described below), a fastener, such as a SIP screw  136  can be inserted into fastener bore  225 , as illustrated in  FIG. 10A , and driven into the exterior edge reinforcement of both the wall component  200  and the underlying floor component  300 , specifically floor plate  220  and footing beam  320  respectively, as shown in  FIG. 10B , to fasten the wall component  200  to the floor component  300 . 
     Plural toe screw housings  288  can also be utilized to fasten each of fixed wall component  200 R, fixed wall portion  200   s - 1 , fixed wall portion  200   s - 3  and pivoting wall portion  200   s - 2  to floor component  300 . In the case of wall component  200 R and fixed wall portions  200   s - 1  and  200   s - 3 , the fastening operation just described can be undertaken during factory fabrication of fixed space portion  102 , described further below. 
     In using toe screw housings  288  to fasten wall component  200 P to floor section  300   b,  it can be seen in  FIG. 10B  that one or more screws  136  will also pass through two sealing structures, wall end cap  246  and floor top plate  252 , which are present at the junction of wall component  200 P and floor portion  300   b.  A similar sealing structure arrangement is present in the cases of the junction between wall component  200 R and floor portion  300   a,  the junction between fixed wall portion  200   s - 1  and floor portion  300   a,  and the junction between wall portion  200   s - 3  and floor component  300   a.  A more detailed description of these sealing structures is set forth in PCT Patent Application No. PCT/US21/56415, entitled “Enclosure Component Sealing Systems,” filed on Oct. 25, 2021 and having the same inventors as the present application, for example in  0092, 0097-0101 and 0112-0120, and in connection with FIGS. 12 and 15, of that application. The contents of that PCT Patent Application No. PCT/US21/56415, entitled “Enclosure Component Sealing Systems,” filed on Oct. 25, 2021 and having the same inventors as this disclosure, are incorporated by reference as if fully set forth herein, particularly including the wall end cap 246 and floor top plate 252 described for example at  0092, 0097-0101 and 0112-0120, and in connection with FIGS. 12 and 15, of that application. 
     In using toe screw housings  288  to fasten wall portions  200   s - 2  and  200   s - 4  to floor portions  300   a  and  300   b,  one or more screws  136  will also pass through sealing structures that are present at the junction of pivoting wall portion  200   s - 2  in its unfolded position and floor portions  300   a/   300   b,  and at the junction of pivoting wall portion  200   s - 4  in its unfolded position and floor portions  300   a/   300   b.  However, these sealing structures, namely wall end interlock A  262  (not shown) and floor top interlock  261  (not shown), differ from wall end cap  246  and floor top plate  252 , in that they are designed to permit the lateral movement of wall portions  200   s - 2  and  200   s - 4  relative to floor portions  300   a  and  300   b.  A more detailed description of these sealing structures is set forth in PCT Patent Application No. PCT/US21/56415, entitled “Enclosure Component Sealing Systems,” filed on Oct. 25, 2021 and having the same inventors as the present application, for example in  0136-0147 and in connection with FIG. 17 thereof. The contents of that PCT Patent Application No. PCT/US21/56415, entitled “Enclosure Component Sealing Systems,” filed on Oct. 25, 2021 and having the same inventors as this disclosure, are incorporated by reference as if fully set forth herein, particularly including the wall end interlock A 262 and floor top interlock 261 described for example at  0136-0147 and in connection with FIG. 17 thereof. 
     After the fasteners are driven into the toe screw housings  288 , the housings can be masked from view by placing an interior baseboard  140  of an appropriate length over the toe screw housings, as shown in  FIG. 10A . The size of interior baseboard  288  can be adjusted prior to installation to accommodate flooring finishes of different types. For this reason, the interior face  142  is provided with a first elongate linear notch  149  (see  FIGS. 9B, 9C ) above bottom edge  144  a sufficient distance to indicate the cut line for accommodating thin flooring, such as floor tiles, and a second elongate linear notch  139  (see  FIGS. 9B, 9C ), above notch  149  a sufficient distance to indicate the cut line for accommodating thicker flooring, such as hardwood flooring. 
     In use, the hook ledge  145  of interior baseboard  140  engages the bevel edge  297  of the toe screw housings  288  positioned along the bottom of the wall component  200 , which thus facilitates the rapid and accurate placement of interior baseboard  140 . The interior baseboard  140  can be secured in place by providing for example hook-and-loop fasteners, or adhesive material, in the fastening recess  138  of the interior baseboard  140 . Toe screw housings  288  and interior baseboard  140  can be made from aluminum, plastics and the like. It is preferred to fabricate the toe screw housing  288  and interior baseboard  140  from foamed polyvinyl chloride (PVC), particularly Celuka foamed PVC. 
     Floor Component ( 300 ) 
     Typically, structure  150  will utilize one floor component  300 ; thus floor component  300  generally is the full floor of structure  150 .

Thus to realize the accordion folded configuration shown in  FIG. 3  roof portion  400   a  is joined to roof portion  400   b  with hinge structures provided between interior edge  412   a  of roof portion  400   a  and second interior edge  412   b  of roof portion  400   b.  Such hinge structures are adapted to permit roof portion  400   b  to pivot through up to one hundred and eighty degrees (180°) of arc about a horizontal axis  405   a,  located proximate the top of roof component  400  and shown in  FIG. 4 , between the roof fully folded position shown in  FIG. 3 , where roof portion  400   b  lies stacked flat against roof portion  400   a,  and the fully unfolded position shown in  FIG. 4 . In turn, roof portion  400   b  is joined to roof portion  400   c  with hinge structures provided between first interior edge  412   b  of roof portion  400   b  and interior edge  412   c  of roof portion  400   c.  Such hinge structures are adapted to permit roof portion  400   c  to pivot through up to one hundred and eighty degrees (180°) of arc about a horizontal axis  405   b,  located proximate the bottom of roof component  400  and shown in  FIG. 4 , between the folded position shown in  FIG. 3 , where roof portion  400   c  lies stacked flat against roof portion  400   b  (when roof portion  400   b  is positioned to lie flat against roof portion  400   a ), and the fully unfolded position shown in  FIG. 4 . 
     Particular embodiments of structural members, which also incorporate hinge structures suitable for joining roof portion  400   a  to roof portion  400   b,  and for joining roof portion  400   b  to roof portion  400   c,  are described in in U.S. Nonprovisional patent application Ser.

Optionally, metal sheets  206  and  217  can be provided with edge structures that facilitate placement of sheets and panels during manufacture. 
     Particular edge structure designs for metal sheets  206  and  217  are described in U.S. Nonprovisional patent application Ser. No. 17/504,883 entitled “Sheet/Panel Design for Enclosure Component Manufacture,” having the same inventors as the inventions described herein and filed on Oct. 19, 2021. The contents of U.S. Nonprovisional patent application Ser. No. 17/504,883 entitled “Sheet/Panel Design for Enclosure Component Manufacture,” having the same inventors as the inventions described herein and filed on Oct. 19, 2021, are incorporated by reference as if fully set forth herein, particularly including the exterior and interior edge structure designs described for example at  00187-00205 and 00212 and in FIGS. 8, 9A-9C, 23A-23J and 24A-24B thereof. 
     A facility suitable for the manufacture of enclosure components  155 , as well as exemplary manufacturing steps, are also described in U.S. Nonprovisional patent application Ser. No. 17/504,883 entitled “Sheet/Panel Design for Enclosure Component Manufacture,” having the same inventors as the inventions described herein and filed on Oct. 19, 2021. The contents of U.S. Nonprovisional patent application Ser. No. 17/504,883 entitled “Sheet/Panel Design for Enclosure Component Manufacture,” having the same inventors as the inventions described herein and filed on Oct. 19, 2021, are incorporated by reference as if fully set forth herein, particularly including the facility suitable for manufacturing the enclosure components  155  of the present invention, as well as exemplary manufacturing steps, described for example at  00178-00186 and 00206-00222, and in FIGS. 22, 23A-23J and 24A-24B. 
     Fixed Space Portion Build-Out and Finishing 
     Referring to  FIGS. 2 and 10A-10C , structure  150  includes a fixed space portion  102  defined by roof component  400   a  (shown in  FIG. 3 ), floor component  300   a,  wall component  200 R, wall portion  200   s - 1  and wall portion  200   s - 3 . (Fixed space portion  102  is also shown edge-on in the shipping module  100  depicted in  FIG. 3 ). It is preferred that the fixed space portion  102  be fitted out during manufacture with internal components, such as kitchens, bathrooms, closets, storage areas, corridors, etc., so as to be in a relatively finished state prior to shipment of shipping module  100 . 
     For example, interior partition walls as desired can be put into fixed space portion  102  during manufacture. Referring to  FIGS. 2 and 10A-10C , there is shown a longitudinal partition wall  126  and a transverse partition wall  127 . Partition walls  126  and  127  each can comprise a foam panel layer, for example three inches (3″) thick, with building panels such as magnesium oxide (MgO) board approximately 0.25 inch (6 mm) thick fastened to each face of the foam panel using a suitable adhesive, preferably a polyurethane based construction adhesive. 
     As shown for example in  FIG. 11A , a first vertical edge of longitudinal partition wall  126  abuts wall portion  200   s - 1 , and a first vertical edge of transverse partition wall  127  abuts wall component  200 R. The second vertical edge of transverse wall portion  127  abuts the longitudinal partition wall  126  proximate to the latter&#39;s second vertical edge, such that partition walls  126  and  127 , with wall component  200 R and wall portion  200   s - 1 , form a rectangular enclosed area that, in the embodiment shown in  FIGS. 2 and 11A-11C , is a bath room  128 . In the embodiment shown, bath room  128  is fitted out during manufacture to include a shower enclosure, a toilet and a wash sink. 
     The open area between transverse partition wall  127  and wall portion  200   s - 3  in the embodiment shown in  FIGS. 2 and 11A-11C  is a kitchen area  129 . In the embodiment shown in  FIGS. 11A-11C , kitchen area  129  is fitted out during manufacture to include cabinets, countertops and cooking facilities. 
     Also, in the embodiment shown in  FIGS. 1 and 2 , wall components  200  are fitted during manufacture and prior to shipment with all necessary door and window assemblies, with the enclosure components  155  being pre-wired for electrical needs. 
     Carrying out the foregoing steps prior to shipment permits the builder, in effect, to erect a largely finished structure simply by “unfolding” (deploying) the positioned components of shipping module  100 . 
     Enclosure Component Relationships and Assembly for Transport 
     It is preferred that there be a specific dimensional relationship among enclosure components  155 . 
       FIG. 2  shows a top schematic view of structure  150  shown in  FIG. 1 , and includes a geometrical orthogonal grid for clarity of explaining the preferred dimensional relationships among its enclosure components  155 . The basic length used for dimensioning is indicated as “E” in  FIG. 2 ; the orthogonal grid overlaid in  FIG. 2  is 8E long and 8E wide; notably, the entire structure  150  preferably is bounded by this 8E by 8E orthogonal grid. 
     Roof portions  400   a,    400   b  and  400   c  each can be identically dimensioned in the transverse direction. Alternatively, referring to  FIG. 3 , roof portion  400   c  can be dimensioned to be larger than either of roof portion  400   a  and roof portion  400   b  in the transverse direction to reduce the chances of binding during the unfolding of roof portions  400   b,    400   c.  Further specifics on dimensioning roof portion  400   c  in the foregoing manner are described in U.S. Nonprovisional application Ser. No. 17/569,962, entitled “Improved Folding Roof Component,” filed on Jan. 6, 2022. In addition, as described in U.S. Nonprovisional patent application Ser. No. 16/786,315, entitled “Equipment and Methods for Erecting a Transportable Foldable Building Structure,” filed on Feb. 10, 2020 and now U.S. Pat. No. 11,220,816, as well as in U.S. Nonprovisional application Ser. No. 17/569,962 mentioned above, friction-reducing components can be used to facilitate unfolding roof component  400 , such as by positioning a first wheel caster at the leading edge of roof portion  400   c  proximate to the corner of roof portion  400   c  that is supported by wall portion  200   s - 2  as roof portion  400   c  is deployed, and by positioning a second similar wheel caster at the leading edge of roof portion  400   c  proximate to the corner of roof portion  400   c  that is supported by wall portion  200   s - 4  as roof portion  400   c  is deployed. 
     In  FIG. 2 , the four wall components  200  are each approximately 8E long, and each of roof portions  400   a  and  400   b  is approximately 8E long and 2.5E wide. Roof portion  400   c  is approximately 8E long and 2.9E wide. In  FIGS. 2 and 3 , each of floor components  300   a  and  300   b  is 8H long; whereas floor component  300   a  is just over 3E wide and floor component  300   b  is just under 5E wide. 
     As shown in  FIG. 2 , fourth wall portion  200   s - 4  is folded inward and positioned generally against fixed space portion  102 , and second wall portion  200   s - 2  is folded inward and positioned generally against fourth wall portion  200   s - 4  (wall portions  200   s - 2  and  200   s - 4  are respectively identified in  FIG. 2  as portions  200   s - 2   f  and  200   s - 4   f  when so folded and positioned). The three roof components  400   a,    400   b  and  400   c  are shown unfolded in  FIG. 1  and shown folded (stacked) in  FIG. 3 , with roof component  400   b  stacked on top of roof component  400   a,  and roof component  400   c  stacked on top of the roof component  400   b.  Wall component  200 P, shown in  FIGS. 2 and 3 , is pivotally secured to floor portion  300   b  at the location of axis  105 , and is vertically positioned against the outside of wall portions  200   s - 2  and  200   s - 4 . In turn, floor portion  300   b  is vertically positioned proximate fixed space portion  102 , with wall component  200 P pending from floor portion  300   b  between floor portion  300   b  and wall portions  200   s - 2  and  200   s - 4 . 
     Sizing the enclosure components  155  of structure  150  according to the dimensional relationships disclosed above yields a compact shipping module  100 , as can be seen from the figures. Thus shipping module  100  depicted in  FIG. 3 , when dimensioned according to the relationships disclosed herein using an “E” dimension (see  FIG. 2 ) of approximately 28.625 inches (72.7 cm), and when its components are stacked and positioned as shown in  FIG. 3 , has an overall length of approximately 19 feet (5.79 m), an overall width of approximately 8.5 feet (2.59 meters) and an overall height of approximately 12.7 feet (3.87 meters). These overall dimensions are less than a typical shipping container. 
     Each of the wall, floor and roof components  200 ,  300  and  400 , and/or the portions thereof, can be sheathed in protective film  177  during fabrication and prior to forming the shipping module  100 . Alternatively or in addition, the entire shipping module  100  can be sheathed in a protective film. Such protective films can remain in place until after the shipping module  100  is at the construction site, and then removed as required to facilitate enclosure component deployment and finishing. 
     Shipping Module Transport 
     The shipping module  100  is shipped to the building site by appropriate transport means. One such transport means is disclosed in U.S. Nonprovisional application Ser. No. 16/143,628, filed Sep. 27, 2018 and now U.S. Pat. No. 11,007,921, issued May 18, 2021; the contents of that U.S. Nonprovisional application Ser. No. 16/143,628, filed Sep. 27, 2018 are incorporated by reference as if fully set forth herein, particularly as found at paragraphs 0020-0035 and in FIGS. 1A-2D thereof. As an alternative transport means, shipping module  100  can be shipped to the building site by means of a conventional truck trailer or a low bed trailer (also referred to as a lowboy trailer), and in the case of over-the-water shipments, by ship. 
     Structure Deployment and Finishing 
     At the building site, shipping module  100  is positioned over its desired location, such as over a prepared foundation; for example, a poured concrete slab, a poured concrete or cinder block foundation, sleeper beams or concrete posts or columns. This can be accomplished by using a crane, either to lift shipping module  100  from its transport and move it to the desired location, or by positioning the transport means over the desired location, lifting shipping module  100 , then moving the transport means from the desired location, and then lowering shipping module  100  to a rest state at the desired location. Particularly suitable equipment and techniques for facilitating the positioning of a shipping module  100  at the desired location are disclosed in U.S. Nonprovisional patent application Ser. No. 16/786,315, entitled “Equipment and Methods for Erecting a Transportable Foldable Building Structure,” and filed on Feb. 10, 2020, now U.S. Pat. No. 11,220,816. The contents of that U.S. Nonprovisional patent application Ser. No. 16/786,315, entitled “Equipment and Methods for Erecting a Transportable Foldable Building Structure,” and filed on Feb. 10, 2020, are incorporated by reference as if fully set forth herein, particularly including the equipment and techniques described for example at  126-128 and in connection with FIGS. 11A and 11B thereof. 
     Following positioning of shipping module  100  at the building site, the appropriate portions of wall, floor and roof components  200 ,  300  and  400  are “unfolded” (i.e., deployed) to yield structure  150 . Unfolding occurs in the following sequence: (1) floor portion  300   b  is pivotally rotated about horizontal axis  305  (shown in  FIGS. 3 and 4 ) to an unfolded position, (2) wall component  200 P is pivotally rotated about horizontal axis  105  (the general location of which is shown in  FIG. 3 ) to an unfolded position, (3) wall portions  200   s - 2  and  200   s - 4  are pivotally rotated about vertical axes  192  and  194  (shown in  FIG. 2 ) respectively to unfolded positions, and (4) roof portions  400   b  and  400   c  are pivotally rotated about horizontal axes  405   a  and  405   b  (shown in  FIGS. 3 and 4 ) respectively to unfolded positions. 
     A mobile crane can be used to assist in the deployment of certain of the enclosure components  155 , specifically roof portions  400   b  and  400   c,  floor portion  300   b,  as well as the wall component  200 P pivotally secured to floor portion  300   b.  Alternatively, particularly suitable equipment and techniques for facilitating the deployment of enclosure components  155  are disclosed in U.S. Nonprovisional patent application Ser. No. 16/786,315, entitled “Equipment and Methods for Erecting a Transportable Foldable Building Structure,” and filed on Feb. 10, 2020, now U.S. Pat. No. 11,220,816. The contents of that U.S. Nonprovisional patent application Ser. No. 16/786,315, entitled “Equipment and Methods for Erecting a Transportable Foldable Building Structure,” and filed on Feb. 10, 2020, are incorporated by reference as if fully set forth herein, particularly including the equipment and techniques described for example at  132-145 and depicted in FIGS. 12A-14B thereof. 
     After unfolding, the enclosure components  155  are secured together to finish the structure  150  that is shown in  FIG. 1 . If any temporary hinge structures have been utilized, then these temporary hinge structures can be removed if desired and the enclosure components  155  can be secured together. During or after unfolding and securing of the enclosure components  155 , any remaining finishing operations are performed, such as addition of roofing material, and making hook-ups to electrical, fresh water and sewer lines to complete structure  150 , as relevant here.
