Description
This invention relates to multistory buildings.
One of the major problems in the attempts to lower the cost of
construction for homes is the necessity for installing the various
service facilities such as water supply, waste, gas, vent, and the
like on the job. This not only necessitates the use of skilled
personnel but, in addition, requires proper programming of the use
of these personnel in order that it will fit into the overall
construction program.
Among the objects of this invention are to provide a building
construction wherein most efficient use is made of skilled
personnel for supplying services; wherein a prefabricated service
wall core unit is provided that is brought in assembled relation to
the job site; and wherein maintenance problems of the final
building are minimized.

DESCRIPTION
Referring to FIGS. 1, 3 and 5, the building embodying the invention
comprises a plurality of horizontally spaced precast concrete
foundation beams 20 resting on foundations 21. Horizontal planks 22
of prestressed or post-tensioned concrete are provided between the
beams to form a first floor and vertical load bearing walls 23 are
provided in overlying relationship to the beams. Additional
prestressed floor planks 24 are extended over the upper ends of the
walls 23 to form the second floor and additional vertical load
bearing walls 25 are provided in overlying relationship to the wall
23 on the planks 24.
The interior of each unit between the walls 23 and floor 24 is
formed with additional nonloading bearing walls dividing the
building into various living areas.
Referring to FIG. 4, the prefabricated foundation beam 20 includes
spaced conduits 26, 27, 28. Conduit 26 is for water supply and
comprises an inlet 29 at the bottom of the beam and an outlet 30 at
one side of the beam. Conduit 27 is for gas supply and has an inlet
31 and an outlet 32 in the side of the beam. Conduit 28 is for
waste or sanitary disposal and comprises an outlet 33 and an inlet
34. Conduits 26-28 are preferably made of plastic and are embedded
in the concrete.
Referring to FIG. 2, a prefabricated service wall core unit 40 is
supported on the floor plank 22 and in part in overlying
relationship to one of the foundation beams 20 and extends upwardly
through the second floor substantially to the roof of the building
so that overall height of the unit is two stories. The core unit
comprises parallel horizontally spaced vertical studs 41, 42 and
top member 43, bottom member 44 and end members 45, 46. A water
conduit 47 is embedded in the unit 40 and supported between the
rows of studs 41, 42. The lower end of the conduit has an inlet
that extends to one wall surface of the core unit 40 as at 48 which
is connected by a connecting pipe 49 to the outlet 30 in the
foundation beam 20 (FIG. 3). The conduit 47 has a portion 50 for
supplying a sink at the lower floor with cold water, a portion 51
for supplying a hot water tank 52 at the lower level, and a portion
53 for supplying cold water to a lavatory 54, water closet 55 and
tub and shower 56 at the upper level. Water flows from the tank 52
through a hot water supply pipe 57 to the lavatory 54 and tub and
shower 56 (FIG. 3).
Similarly, a gas supply pipe 60 is embedded in the wall and extends
through the bottom of the wall core unit and is connected to the
outlet 32 of the foundation beam. Pipe 60 extends to the hot water
tank 52 and furnace 61.
Referring to FIG. 7 which is a view showing the wall core unit with
only a portion of the conduit therein, a waste conduit 65 extends
vertically through the bottom and top walls of the core unit 40,
the top forming a venting stack. The lower end of the pipe is
connected by a coupling 66 to a conduit 67 that extends to the
waste inlet 34 in the foundation beam 20. Interconnecting portions
68 extend from the lavatory 54 on the upper level, interconnecting
portion 69 extends from the tub and shower 56 on the upper level,
and interconnecting portions 70, 71 extend from the sink and washer
connection at the lower level, respectively. These portions 69, 70,
71 are vented in accordance with required plumbing practice through
vent portions 72, 73, 74 and 75 to the stack.
Referring to FIG. 7 the service wall core unit further includes an
electrical connection box 80, an electrical service conduit 81
extending from the box to an end wall of the core unit 40. The box
has a plurality of coiled wires 82 to 90 therein. Each wire is a
predetermined length and coded, as by color coding, so that it can
be fished out of the wall and extended to various portions of the
building. The unit further includes a clothes chute 91 having an
inlet 92 above the second floor and an outlet 93 below the second
floor.
As further shown in FIGS. 2 and 3, a vertical stack 96 extends and
provides a vent from furnace 61 and hot water tank 52. A dryer, not
shown, may be similarly vented to a stack 97.
In practice, the service wall core unit 40 is prefabricated at a
point removed from the job site with all of the pipes and
electrical connections embedded therein. The unit is then
transported to the job site where all that is necessary is to make
the connections to the service inlets and pull the wires for wiring
the various portions of the building.
Inasmuch as the conduits embedded in the building extend for the
full height of two stories thereby enabling supply to the two
stories, the number of connections made on the job is minimized not
only facilitating construction but maintenance as well.
In accordance with the invention, the various conduits embedded in
the wall are preferably made of plastic except for the water and
gas pipes which may be made of metal.
In the form of the invention shown in FIG. 9 the core unit is shown
as comprising a body of foam plastic material in which the various
conduits are formed.
In each of the forms of the invention, in the exposed areas of the
wall surfaces of the core unit 40, prefabricated sheets can be
provided with openings at the various conduit connections to form a
finished surface. These sheets can be applied either at the point
where the core unit is made or at the job site.
In the form of the invention shown in FIG. 9, the integral
two-story wall is molded in a single piece. In the form of the
invention shown in FIG. 10, the wall, similar to FIG. 9, is molded
in a rectangular frame 94 which has a bottom wall 95 during
molding. The frame 94 becomes an integral part of the core unit and
performs the same function as the frame defined by members 43, 44,
45 and 46 in the form of the invention shown in FIGS. 1-8. The wall
95 also becomes an integral part of the core unit and forms one
vertical surface when the core unit is erected. The wall contains
the various surface elements as in the form shown in FIG. 9.
