Abstract
PREFABRICATED COMPACT SERVICE CORE
ABSTRACT OF THE DISCLOSURE
Walls of the prefabricated compact service core structure are higher than the total height of the floor, wall and ceiling structure of an ordinary one-storey resi-dential building, but lower than the total height of a two-storey building of any kind. The height of the walls is large enough to e.g. accommodate the serviced fixtures of complete main floor bathroom, kitchen, and possibly laundry and utility rooms, as well as lower parts of the same rooms of the second storey of a two-storey structure.
On the other hand, the height is small enough to make the prefabricated compact service core structure possible to ship on standard low trailers anywhere in the world. The prefabricated compact service core structure allows for factory completion of all major plumbing, heating, ventil-ation, and electrical work for a two-storey building, and easy on site hook-up to sewer, water, gas and electrical services from the bottom of the prefabricated compact service core structure ventilation and possibly electrical services may be extended above the top of the core through one or more extension service panels. As all portions of the floor of both storeys and high plumbing wall are suspended, premanufacturing of the service core in the plan can easily match all custom designed floor heights or deviations from them usually originating from the supply of building lumber of irregular dimensions.

Description
PREFABRICATED COMP~CT SERVICE CORE
FIELD CF THE INVENTION
The present invention relates to prefabricated buildings and more particularly to service cores for multi-storey prefabricated bulldings.
~ACKGROUND
:
one problem area in the prefabrication, shipment and assembly of two-storey prefabricated buildings is the installation and assembly of the building services, for example plumbing, heating, ventilation and electrical services. With a prefabricated building it is often desired to have the services concentrated in the service core of the building. To effect thls, some manufacturers are prefabricating either plumbing walls or complete single storey service units. Multi-storey units are not manufactured because a two-storey structure providing plumbing, heatln~, ventilation and electrical servlces ls not transportable either in a vert~cal or horlzontal posltion.
Whlle attempts have been made to stack two one-storey servlce unlts, thls ls not practlcablé for a number of reasons. The resultant assembly has a double structure including the celllng of the lower unit and the floor structure from the upper unit. In addition, access to ~ q~

- -. . . :
-` 20~1308 service connections between the stacked units must be maintalned. Furthermore, this requires the performance of highly professional service connecting work on the build-ing site. This makes the prefabrication of stacked units of this type ineffective.
The present inventlon addresses this problem and provides a service core for a multi-storey building that may conveniently be shipped and that maximizes the factory content of the plumbing, heating, ventilation and elec~ri-cal work.
SUMMARY
Accordlng to the present inventlon there is pro-vided a prefabrlcated service core for a building having first and second stories, the servlce core comprlsing:
a service wall extending the height of the flrst storey and a part of the helght of the second storey;
upper and lower floor sections secured to the service wall to provide a first storey core section there-between and a second store~ core section above the upper floor section;
servlced f ixtures mounted ln the flrst and second storey core sections; and buildlng services carried by the service wall and coupled to each of the servlced flxtures.

20~308 Because the service core of the invention is more than one storey hlgh, it includes not only the entire serviced space of the first storey, but also the lower part of the serviced space of the second storey. The upper part of the second storey can easily be erected on site from factory premanufactured extension panels during the erectlon of the entire bullding structure. one or more of the extension panels may include a small propor-tion of the services, for example a single vent stack from the sewer lines, a ventilation duct from the upper part of the second storey of the service core, and some other com-ponent6 if needed. All of the extenslon wall panels can be shlp~ed from the plant to the bulldlng slte ln a separ-ate panel package.
The system may easily be applied to four-storey bulldings and to each two additional floors. In apartment and hotel develoPments where the sources of heat and hot water are centrally located, the second floor plan may be exactly the same as the ~lrst floor plan. The service core may be arranged to accommodate any layout of the plumbing flxtures and servlced faclllties. It may accom-modate any shape of the structure, whatever is needed for the convenlence of the servlce layout.
The service core is preferably a rectangularly ;, . . ~ -. . . . .
3(~8 shaped structuxe with three perimeter walls and an intern-al service wall that accommodates plumbing, heating, ven-tilation and electrical services for a back t~ back layout of the serviced fixtures. Four perimeter walls may be employed lf desired.
Preferably, the two side walls perpendicular to the service wall are load-bearing walls that support the two floor sections.
The three side walls may be constructed with exterior wall sheathing on thelr lnside faces. Similar sheathing may be used on the faces of the servlce wall.
This ln combinatlon with the floor sections creates a rlg-ld box structure to support such fragile wall finishes as ceramlc tlle applled over drywall. Thls protects the wall flnlsh against cracking durlng loadlng, unloadlng and other rou~h handllng of the servlce core structure.
The walls may be constructed with double plates at the top and bottom, wlth the plates of two ~olnlng walls overlapping at the corners. This provldes a secure, rlgid connectlon Or the w811s to one another. Thls rlgld-lty may further be enhanced by 8crewed connectlons of the ~loor headers to the walls.
The top Or the servlce core ls protected agalnst the weather by a sloped deck arrangement and a protectlve .~.,, ` . , ~

. Openings in the walls of the core are also preferably weather protected and arranged so as not to obstruct the erection of the building. They are arranged to allow for easy removal of those portions of the sheathing over lntended wall openlngs whenever needed dur-i lng the constructlon of the bulldlng.
The ends of the load-bearlng slde walls have double end studs that are provlded wlth plck up holes so that the complete unit can be suspended from a cable assembly.
Those are ~arts of the protective sheathing of the core which are to be removed during or after the bulldlng erectlon are factory pre-cut to minimize the creatlon of dust ln the service core.

DETAILED DESCRIPTION
Referring to the accompanylng drawings there is lllustrated a servlce core 10 for a two-storey building.
The servlce core lncludes a servlce wall 12 fabrlcated from a double top plate 13, vertlcal studs 14 and a double bottom plate 15. A sheath 16 of structural materlal, for example an approprlate grade of plywood, ls secured to the studs and plates on one slde o~ the wall. On the other slde of the wall is a sheath 18 that is secured over the studs after services have been installed in the service wall. The service wall accommodates the varlous servlces reguired by the building includlng water plpes 20, draln plpes 22, electrlcal llnes 24 and alr ducts 26. Mounted on the service wall 12 ls a lower floor wlth a sectlon 28 ,. : , . ....

~, ;~0:11308 on one side of the wall and a section 29 on the opposite side. The floor includes ~oists 30 that run parallel to the servlce wall and are secured at opposlte ends to headers 32 as lllustrated most partlcularly ln Figure 3.
The ~ois~s and headers support floor panels 34 and 35. An upper floor with sectlons 36 and 38 ls llkewlse composed of joists 38 parallel to the service wall 12 and headers 40 supoprting floor panels 42 and 43.
The floor headers are fastened to two side walls 44 and 46 extended across the opposlte ends of the servlce wall 12. These are load-bearlng walls, each wlth a double top plate 47, a serles of vertlcal studs 48 and a double bottom plate 49. A structural load-bearlng sheath 50 ls secured to the studs and the plates of each wall, on the lnslde. At each end of the wall are double studs 52.
An additional perlmeter wall 54 extends between the slde walls 44 and 46, parallel to and spaced from the servlce wall 12. Wall 54 has a double top plate 55, ver-tlcal studs 56 and a double bottom plate 57. Sheathlng 58 covers the lnslde face of the wall except for two openlngs 60, one between the upper and lower floors and one above the upper floor. Double studs 62 are located on opposlte ~;
~ sldes of the openlng 60. A slmllar openlng 68 18 provided ;~ ln the wall 46, again with double studs 64 on lts opposite ' - ~

20~1308 sides.
The top plates 47 and 55 of the walls overlap at the corners and are fastened together ~nd to the double studs at the corners to provlde a rlgid box structure that resists deformatlon.
Fastened to the studs on each side of each open-lng 60 are blocks 64 that support removable decks 66 whlch close the openlngs for transportatlon purposes.
A transverse brace 68 extends between the slde walls 44 and 46, near the top on that slde of servlce wall 12 opposlte the wall 54. Thls brace 68 supports a sheath 70 that covers the slde of the servlce core opposlte the wall 54. As lllustrated most partlcularly ln Flgure 6, certaln areas of the sheath 70 are outllned by long slots 72 through the sheath so that those areas can be opened readily durlng or after lnstallation wlth a minimal amount of dust qeneratlon.
The top of the service core ls closed wlth two decks 74. These are supported on blocks 76 extendlng along the top o~ the servlce wall 12, so that the ed~es of the deck8 are 8upported above the top o~ the wall. At the plate 55 Or wall 54, blocks 78 are lower and are posl-tloned 80 that the top surface o~ the deck 74 ls flush wlth the top of the double plate 55. Along the opposlte r . ~

20il308 side of the service core, the deck is supported on the top of the brace 68 at the same level as on the blocks 78.
The decks 74 thus slope downwardly away from the service wall.
A waterproof membrane 80 is placed over the top of the entire core and fastened in place.
Figure 1 illustrates an alternative to the wall 54 with its opening 60. In this case, the wall is a solld wall 82 wlth no openings, access to the servlce core being through openlngs ln wall 46.
The servlce core as illustrated includes a lower floor bathroom 84 between the lower and upper floors.
Thls lncludes a tollet 86, a slnk 88 and a bath tub 90 all mounted ln the unlt and coupled to the appropriate plumb-ing lines ln the service wall. Immedlately above the bathroom 84 ls a second bathroom 92 e~ulpped wlth a toilet 94, a slnk 96 and a bath tub 98, agaln coupled to the water and drain llnes in the service wall.
On the opposite side o~ the service wall ~rom bathroom 84 i8 a kltchen servlce area 100. Thls accommo-dates a ran~e 102, a counter 104 wlth a slnk 106, cup-boards 108 and 110 and a range hood 112. Electrical and plumblng connectlons are made to the approprlate supplles wlthin the servlce wall.
' : ' `
' . '~ , ' ' ~ '' ' 20~1308 Above the kitchen area 100 is a furnace room with a floor 114 raised on joists 116 above the floor 37.
This leaves a chamber 118 for air return ductlng and the llke. The furnace room accommodates a furnace 148 and a water heater lS0.
The upper bathroom 92 is illustrated as including stairs 120 leading up to the upper access open-ing 60 whlch ls at the same level as the raised floor 114 ln the furnace room. As lllustrated ln Figure 5, thls level is colncldent wlth the floor level of the upper storey of the bullding. This arrangement can be used to shorten the servlce core somewhat where thls is deslred.
In alternatlve embodlments, the stalrs may be ellmlnated or lndeed may lead to a raised floor in the service core.
The service core ls completed durlng erectlon of the buildlng by lnstalllng wall extensions above the walls of the partial upper storey of the service core. Where openlngs are provlded ln the walls of the upper storey, the blocks 64 are removed, the double plate is cut at the top of the openlng and ~rame tles 122, whlch are addltlon-al stuas, are lnstalled on elther 81de of the openln~.
The8e are secured tO stud9 62 and stud8 extendlng along the 81de8 of matchlng openlngs in the wall extensions.
As lllustrated most partlcularly ln Flgure 7, . .

::. .: : : :: -;Z011308 the extension walls may include extension walls 123 and 124 that are secured to the tops of the load-bearing walls 44 and 46 respectively of the service core. A further extension wall 125 mounts on the top of the addltional wall 54. The service wall may be extended with an extens-ion wall 126 that includes a vent pipe 12B exposed at the bottom of the extension wall throu~h a notch 130 so that it ls accessible for connection to the matchlng vent pipe in the service wall. The extenslon of the service wall may have an upwardly extended section that pro;ects beyond the ceillng of the second storey where this is desired.
As shown most particularly in Figures 1 and 6, the installation of the extension walls on the service core can be done without removing the top decks 74. The extension of the decks above the ad~acent top plates pro-vides for appropriate alignment of the extension walls.
In the case of the extension of the servlce wall, it is simply necessary to remove a thin strlp of the membrane between the raised edges of the top decks and to lnsert the bottom edge of the extenslon lnto the slot between the decks. The rai5ed edges of the decks also protect the upper end of the vent plpe where lt emerges from the top o~ the servlce wall.
The openlngs ln the wall sheathlng may be closed .- . , : ~
20~L~3(~8 by integral parts of the sheathing outlined with slots 132 so that the openlngs can be formed wlth a minlmal amount of sawlng, leaving a mlnimum amount of sawdust in the service core ln the completed building. An arrangement of this sort is shown in Figure 4, where the removable panel 134 is separated from the remainder of the sheath 58 by slots 132.
AS illustrated in Figure 6, openings 140 are formed in the corners of the service core, through the double studs at the corners. These serve for the connec-tion of a sling 142 to the unit. The sling is used for loading and unloadlng the service core for shipping. The wall 46 ls shown ln Figure 6 as havlng two air return ducts 144 and two air supply ducts 146 for connection to the heating system of the remainder of the bullding.
These are connected through the servlce wall to the ~urnace 148. A serles of electrlcal outlets 152 are carried on the wall 46 as well. Where desired a servlce cabinet 154 may be built ln to house a breaker panel, a water meter and the like. Thls lnterlor wall of the service core may also accommodate a thermostat 156 and a humidlstat 158.
While one particular embodlment of the lnventlon has been described ln the foregoing, it is ~o be under-.
2~1i30~3 stood that other embodiments are possible within the scope of the inventlon. In particular, the layout of the serv-lce core equipment and the arrangement of the pipes and ducts may be arranged in a variety of different ways. The fixtures illustrated ln the accompanying drawings may be replaced with alternative forms of fixture. The invention is therefore to be considered limited solely by the scope of the appended Cla1ms.

::. .: : : :: -;Z011308 the extension walls may include extension walls 123 and 124 that are secured to the tops of the load-bearing walls 44 and 46 respectively of the service core. A further extension wall 125 mounts on the top of the addltional wall 54. The service wall may be extended with an extens-ion wall 126 that includes a vent pipe 12B exposed at the bottom of the extension wall throu~h a notch 130 so that it ls accessible for connection to the matchlng vent pipe in the service wall. The extenslon of the service wall may have an upwardly extended section that pro;ects beyond the ceillng of the second storey where this is desired.
As shown most particularly in Figures 1 and 6, the installation of the extension walls on the service core can be done without removing the top decks 74. The extension of the decks above the ad~acent top plates pro-vides for appropriate alignment of the extension walls.
In the case of the extension of the servlce wall, it is simply necessary to remove a thin strlp of the membrane between the raised edges of the top decks and to lnsert the bottom edge of the extenslon lnto the slot between the decks. The rai5ed edges of the decks also protect the upper end of the vent plpe where lt emerges from the top o~ the servlce wall.
The openlngs ln the wall sheathlng may be closed .- . , : ~
20~L~3(~8 by integral parts of the sheathing outlined with slots 132 so that the openlngs can be formed wlth a minlmal amount of sawlng, leaving a mlnimum amount of sawdust in the service core ln the completed building. An arrangement of this sort is shown in Figure 4, where the removable panel 134 is separated from the remainder of the sheath 58 by slots 132.
AS illustrated in Figure 6, openings 140 are formed in the corners of the service core, through the double studs at the corners. These serve for the connec-tion of a sling 142 to the unit. The sling is used for loading and unloadlng the service core for shipping. The wall 46 ls shown ln Figure 6 as havlng two air return ducts 144 and two air supply ducts 146 for connection to the heating system of the remainder of the bullding.
These are connected through the servlce wall to the ~urnace 148. A serles of electrlcal outlets 152 are carried on the wall 46 as well. Where desired a servlce cabinet 154 may be built ln to house a breaker panel, a water meter and the like. Thls lnterlor wall of the service core may also accommodate a thermostat 156 and a humidlstat 158.
While one particular embodlment of the lnventlon has been described ln the foregoing, it is ~o be under-.
2~1i30~3 stood that other embodiments are possible within the scope of the inventlon. In particular, the layout of the serv-lce core equipment and the arrangement of the pipes and ducts may be arranged in a variety of different ways. The fixtures illustrated ln the accompanying drawings may be replaced with alternative forms of fixture. The invention is therefore to be considered limited solely by the scope of the appended Cla1ms.
