No. 705,391 Int. Cl. E041) 1/348; E04c 3/34 US. Cl. 52-79 12 Claims ABSTRACT OF THE DISCLOSURE A building constructed from a number of prefabricated modules. Each of the modules has solid spacing ribs on its outer surface, which ribs cooperate with similar ribs on adjacent modules to define a series of spaces between adjacent modules. The modules are stacked and arranged according to a predetermined building plan, and selected spaces defined *by adjacent sets of cooperating spacing ribs are filled with poured concrete to form support columns for the building.

This invention relates to a building construction in which a number of building modules are arranged to form the structure.

ADVANTAGES OF THIS INVENTION There are numerous advantages to a system in which prefabricated building modules are arranged to form a building structure. For example, conventional building structures require the erection of forms, the insertion of reinforcing steel and the pouring of concrete to construct the building framework at the site. The modular construction of the present invention requires only a basic support underlying the entire building, and a conventional build ing framework is not required or used.

Additionally, the modular building construction of the present invention obviates the problem of damage to mechanical facilities which often occurs with prior art reinforced concrete systems. For example, in prior art systems, piping, conduit and duct work are generally installed in the concrete forms before the concrete is poured. Often these components will be damaged during the pouring of the concrete, and in order to repair the damage after pouring, it is necessary to tear up the concrete. In contrast, as is described below, with the modular building construction of the present invention, the mechanical facilities are installed after the modules are in place. In this manner, alterations or repairs to mechanical facilities are simplified and can be made without tearing up the concrete.

Furthermore, in accordance with the illustrative embodiment of the present invention, the modules are cast of concrete so that all interior surfaces are completely finished. Hence, there is no need to apply plaster or other wall surfacing to the interior walls of the modules. Such modules are fireproof, and the arrangement of-the modules according to the present invention provides excellent soundproof qualities.

In the illustrative embodiment, some of the modules are the size of a small room so that they can be finished and equipped as a complete room unit subsequent to casting thereof. Thus, these modules can be assembled at the site without need to install additional interior equipment. The only remaining installation required is the connecting of mechanical facilities.

Various other advantages of the modular building construction of the present invention will become apparent from the following description thereof.

United States Patent SUMMARY OF THE INVENTION In accordance with the present invention, there is provided a building comprising a number of prefabricated building modules having a horizontal wall member and at least two opposing, vertically disposed side walls. Each of the modules has solid spacing means extending outwardly from the exterior surface of at least one of the opposing side walls to provide space between the sides of adjacent modules. The solid spacing means of each module is in contact with the adjacent module to define chases for receiving a flowable, hardenable material, such as concrete. A flowable, hardenable material fills some but not all of the chases to connect adjacent modules to each other and to provide support columns for the building.

The spacing means in the illustrative embodiment of the invention comprise ribs having the same lateral location on respective sides of modules. When modules are placed vertically, one above the other, the contacting ribs of adjacent modules will form continuous vertical chases for receiving the flowable, hardenable material.

The use of support columns formed by pouring a flowable, hardenable material in selected chases defined between adjacent modules is unique and offers a modern structure with much air space between adjacent modules. Hence, ready access between adjacent modules is provided so that it is not necessary to drill through a thick wall if a service connection is subsequently necessary between the modules. In contrast, prior art prefabricated systems such as disclosed in US. Pat. No. 3,331,170 and French Pat. No. 1,269,080 require that concrete be poured to fill all air spaces between adjacent modules. In such prior art systems the modules must be relatively close to each otherotherwise the amount of concrete required to fill all air spaces would be very large and prohibitively expensive. The relative closeness of adjacent modules of such prior art systems does not allow much space for mechanical facilities, and in addition limits the soundproofing qualities of the structure.

In the illustrative embodiment, the exterior surfaces of the opposing sides of the modules are bevelled with respect to a vertical plane. This expedient achieves a positive mechanical purchase between the modules and the hardened material between adjacent modules, and makes it possible to provide the hardened material in only selected chases between adjacent modules.

DESCRIPTION OF SPECIFIC EMBODIMENT The building illustrated in FIG. 1 is formed of a number of modules 22 which are stacked vertically and aligned horizontally. 'Each of these modules 22 is formed of pre-cast reinforced concrete and has solid spacing ribs 24, 26 and 28 (best seen in FIGS. 4-6) integrally cast therewith and extending outwardly from the side walls 30, 32 and top wall 34. The spacing ribs of each module have the same lateral location on respective side walls 30 and 32 and on top Wall 34. In this manner, spacing ribs of adjacent modules can be placed in contact with each other and vertical chases will be formed between adjacent modules. Such chases provide air space to achieve soundproofing qualities and also within selected chases there is poured concrete which, when hardened, provides support columns 110 for the structure.

The internal corners 36, 37, 38 and 39 are coved to achieve maximum strength. The external surfaces 40 and 41 of side walls 30 nd 32 are bevelled with respect to a vertical plane (surface 41 being bevelled upwardly and outwardly), as shown most clearly in FIG. 4. This expedient is useful to provide a positive mechanical purchase when the concrete is poured between the side walls of adjacent modules.

In the illustrative embodiment, the spacing ribs on the top wall 34 of the modules contact the exterior surface of the bottom wall, i.e., the fiat undersurface 45, of the module directly thereabove. The air spaces between vertically adjacent modules provide excellent soundproofing qualities and mechanical facilities can be provided in both the vertical and horiontal chases formed between adjacent modules. If desired, concrete may be poured to fill some of the horizontal chases and thus form horizontal beams extending between and supported by vertical support columns formed in vertical chases located on opposite sides of a given module, which horizontal beams provide additional lateral stability for the vertical columns and, when the beams are in direct contact with the fiat undersurfaces 45 of the modules immediately above, help to support those vertically adjacent modules. As shown in FIG. 7, inserts 46 are provided to close the openings defined by vertically adjacent modules. Trim 47 is connected to the otherwise exposed ends of inserts 46 at the building facade, to provide an attractive appearance.

As best seen in FIGS. 4 and 9, the walls of each module define four apertures 48, 49, 50 and 51 which extend the entire length of the module, and are preferably located near the corners formed by adjoining walls of the module. These apertures are provided in a manner so that when the modules are aligned end to end, the apertures defined by one module will register with the apertures defined by the adjacent modules, thereby providing openings for tie rods (see FIG. 6) connecting end to end modules to each other. Nuts 62 are screwed onto the ends of the tie rods to retain them within the apertures. Such tie rods provide additional support for the structure.

Where a hallway is desired, floor planks 66 and ceiling planks 68 may be inserted as shown most clearly in FIGS. 3 and 10. The floor and ceiling planks also define apertures for receiving the tie rods 60; and the ends 69 of the planks are cemented to the ends of the contacting modules (FIG. 10).

A typical floor plan is illustrated in FIG. 8, in which twelve modules are aligned to provide an efficiency apartment 70 and a two-bedroom apartment 72-. The efiiciency apartment 70 includes a living room-sleeping area 76, a dining room-kitchen 78, an entrance hall and a bathroom 82 The two-bedroom apartment 72 includes a living room-dining room area 84, a kitchen 86, two bedrooms 88, 89, an entrance hall 90, two bathrooms 92, 93 a large walk-in closet 94 and a balcony 96.

The modular units are formed by pouring concrete into molds in which are positioned the necessary reinforcing steel rods. After the modular units are formed, certain special components, including kitchen and bathroom cabinets, counter tops, plumbing fixtures, heating and air-conditioning systems, windows and doors, ceramic tile, lighting fixtures, etc., are installed. The module can now be shipped to the site of construction and it can be placed in a predetermined position with all of the interior fixtures already in place.

The construction of the building commences with the preparation of the underlying support structure 42, as shown most clearly in FIG. 2. In the embodiment shown, structure 42 is poured in monolithic form. The first module is then set in place, and any mechanical facilities which are to be connected to the first unit or adjoining units are set in place. Reinforcing steel 98 is set in the areas in which structural columns will be provided. In some in stances, transverse horizontal beams are required. To this end, some of the modules are formed with sections of the spacing ribs omitted, as shown in FIG. 9. In this manner, when two rows of adjacent modules have been aligned, mold members 101 and 102 are placed in opening at the bottom thereof, reinforcing rods 103 are placed in the opening, and concrete is poured in the opening to provide transverse horizontal beams 104 that extend between and are supported by vertical support columns formed in vertical chases between horizontally adjacent modules. To facilitate placement of the mold members, member 101 may be trapezoidal in cross section and member 102 may be a parallelogram in cross section. They may be formed of any suitable fire-proof material.

Once the first unit is set in place, adjacent units are then set around it. Concrete is thereupon poured in the areas where reinforcing has previously been installed, to form support columns (best seen in FIGS. 1, 3 and 6). Additional units are subsequently added, as called for in the plans.

As a specific example, in the illustrated embodiment of the invention, the modules are twelve feet wide by eight feet high by ten feet deep. These dimensions can of course be varied without departing from the invention. In the illustrative embodiment, each module is pro-cast of reinforced concrete as a single monolithic unit. Such construction provides excellent fireproof quality and production efiiciency.

It is to be understood that the embodiment shown is for illustrative purposes only, and many modifications or substitutions may be made without departing from the spirit and scope of the present invention.
