ABSTRACT:
This invention relates to a water closet carrier and waste discharge system which is useful, for example, in a building module which provides readily-accessible utility connection or connections for a room, having plumbing fixtures therein, for a building, such as single or multiple family dwellings, condominiums, apartment houses, motels, hotels, offices, industrial or other kinds of buildings. Also, the module may be used to provide two rooms which are constructed adjacent each other, and installed at a building site as a single, larger building module.
This invention is primarily concerned with construction of a water closet carrier which is readily installable on flooring structure as well as a waste discharge system which is installed on or above the flooring structure. Such “flooring structure” includes any kind of support structure having suitable strength to support a building module or upon which the module is intended to be placed. “Flooring structure” includes, of course, rough flooring, slab flooring, finished or unfinished flooring or any other suitable support structure upon which a room or rooms can be built. “Flooring structure” also includes “subflooring” structure provided it is suitable, or made suitable, to receive and hold the module as part of a building.
The water closet carrier and the waste discharge system are particularly useful in a building module which is comprised of two adjacent, parallel frames, each of which are approximately the size of a wall of a room. The parallel frames are comprised of vertical studs. A wall may be readily built upon each frame, each wall forming one wall of a room. “Adjacent” means that they are disposed near each other. The frames are fixedly spaced apart approximately 12 to 18 inches, preferably about 14⅛ inches.
Within the two parallel frames, there is included a water closet carrier for supporting one or more off-the-floor water closets disposed on opposite sides of the frames and the walls which may be constructed on such frames. Waste conduits, waste conduit junctions, hot and cold water conduits and other utility conduits and lines are conveniently located between the two frames. Such conduits and lines preferably extend to the ends, or near the ends, of the frames, where they are readily accessible for connection to the sewer, hot and cold water supply, electrical service supply, gas supply or other utility supply, outside the module. The bottom structure of the module lies in a plane. By “bottom of the module” is meant such bottom plane. It is to be appreciated that the module could have downward extensions, which would extend downwardly through such bottom plane, but that is not preferred. It is preferred that the bottom of the module be flat and sit flat on “flooring structure”. “Flooding structure” includes “subflooring” and other structure suitable to receive and hold the module. Thus, a compact module is provided, to which all or most utility connections can readily be made during its own manufacture and during the construction of the building in which it is to be placed.
The larger building module, in its simplest form, has no floor and preferably has a ceiling although it is not required that there be a ceiling. The larger building module is adapted to be built and transported to a building site and set in place on flooring structure. A convenient size for the larger module is approximately 8½ feet wide and approximately 15 feet long. The ceiling comprises drywall screwed, riveted or otherwise attached to ceiling joists which extend across the top of the larger building module. The larger module may comprise one room, but is preferably comprised of two rooms which are toilet and bath or shower combinations. The great convenience of the larger building module is that it retains the convenience of the smaller building module. That is, the larger building module likewise has ready accessibility to all of the plumbing connections and utility connections, for plumbing, electrical and other fixtures inside or outside the building in which it is to be placed. Thus, accessibility for connections to sewer, electricity, gas, hot and cold water and dryer vent and any other desired utility is provided in such larger building module, just as in the smaller building module.
“Plumbing fixtures” includes off-the-floor water closets, lavatories, sinks, vanities, urinals, baths, showers, or combinations thereof, and any other equipment which requires water supply or waste discharge.
The smaller building module is readily incorporated in the larger building module which is preferably comprised of two rooms, with the smaller building module forming the partition, or “chase wall” as it is called in the trade, between the two rooms. Thus, a wall constructed on each side of the smaller building module forms one wall of each room. Mounting connections for off-the-floor water closets, lavatories or other plumbing fixtures may readily be included on or in the smaller building module. Waste conduit connections, vent connections, hot and cold water connections, electrical connections, gas connection and dryer conduit connections for all plumbing and light fixtures are conveniently provided by the smaller building module, even when it is incorporated in a larger building module.
Vertical vents are required for each plumbing fixture. Such vertical vents may readily be disposed along the waste discharge lines and may be combined within the smaller module by nearly horizontal connections. Each vertical vent must extend at least 6 inches above the plumbing fixture before turning approximately horizontal. In the modules, vertical vents may readily be extended two, three or four feet before turning to combine with other vents.
The preferred embodiment of the larger building module has no floor and is constructed, preferably, of four walls to be set on flooring structure. Of course, the larger building module may be constructed so as to have more than four walls. Preferably and most efficiently, the two rooms of the larger building module are comprised of two toilets and two bath and shower combinations. However, only bath or shower may be included, as desired. Also, lavatory, or wash basin, vanity, medicine cabinet, mirror and light fixtures may be provided in one or both rooms, as desired. Connection to all such fixtures is provided by the smaller building module as previously discussed. Finished flooring may be completed after the module is installed. Alternatively, the module may include a floor, but that is a less efficient and less economical method of construction.
The rooms, while preferably toilets with lavatory, or wash basin, bath and shower, may otherwise be laundry rooms, kitchens, custodian rooms, rest rooms or other kinds of rooms requiring one or more waste conduits to carry away waste water and, likely, requiring cold water and electricity and, possibly, hot water. Such rooms may further require gas, dryer vent and other lines or conduits. The smaller module is readily adapted to provide the needs of all such rooms. The larger module is also readily adaptable to meet the requirements of a handicapped facility.
BACKGROUND OF THE INVENTION
In the prior art, previous off-the floor-water closet carriers have used the waste conduit junction to connect and to support the front and back of water closet carriers. While such waste conduit junction may be used to add strength to the carrier in this invention, the strength and rigidity of the carrier in this invention comes primarily from structural means, such as, for example, two side plates, which are independent of the waste conduit junction.
In the prior art, connections to waste disposal conduits are made under the flooring of a house. Such construction method is time-consuming and does not always produce the workmanlike results that can be produced in a shop. Nor does the prior art method lend itself to a production line as does the building module concept of the invention.
The smaller module, comprised of the two parallel frames, provides readily-accessible was
