Multiple Story Building Construction

Abstract

A multistory building comprising a plurality of laterally spaced parallel foundation beams which have prestressed horizontal planks thereon and vertical load bearing walls on the planks. A second set of prestressed horizontal planks are provided to form a second floor. A service wall core unit is mounted on the first floor. The service wall core unit comprises a body which has service conduits therein that are connected to supply conduits in the foundation beams.

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.
