Field of the Invention This invention relates to the field of modular building construction in which building modules are manufactured in an assembly-line process in the field or in the factory, and thus fully precompleted with all trades integrated to the largest possible extent, building mod u'les are assembled into the form of the building i.e. into a modular cluster.

2. Description of the Prior Art This invention has found its antecedence in the related invention of this applicant filed under the title Coordinated Modular Building Construction as mentioned in the preceding chapter. It represents its preferred embodiment with respect to the problem of the construction of doubled walls and doubled floor structures.
The problem of the duplicity of the structure, which is inherent to any modular technique using fully, or partly the assembly mode described before, is well known in the technical society in the world today and it is described in the literature under an inaccurate term The Problem of the Structural Redundancy. It is generally believed, that the mentioned problem is detrimental to any modular construction employing such redundant structural concept.
This applicant submits, that such standpoint is narrow and superficial and contends, that successful solution can be found by a thorough scientific exploration of the problem in it complexity. The economical analysis indicates, that the costs of the structure performed in accordance with this invention do not exceede the cost of the conventional construction technique, thus offering substantial savings achieved through the advantage of modular construction with all trades integrated before installation to place.
OBJECT OF THE INVENTION The primary object of this invention is to confirm the economical feasibility of the concept described in the preceding invention submitted under the title Coordi nated Modular Building Construction, thus achieving all objects described there.

This particular invention deals with the very critical consequence of such a mode of assembly, namely with the problem of the doubled wall structure and the doubled floor structure.
More specifically, this invention deals with particular features of the concept disclosed in the closely related invention cited before.
Modular structure, therefore, recognizes coordinating dimensions denoted as the modular height, modular width, and modular depth expressed in multiples denoted as the segmental depth.
Modular structure is constructed of components flat panels assembled in an assembly line process with the assistance of a special mechanical apparatus denoted as the mechanical jig. Advantages of such a method are explained in the above cited invention.
Connecting means needed for the structural interconnection of modules are integrated within modular structure and their position governed by the coordinating system described in the cited related invention.
Congruent horizontal structural components, i.e. floorand ceiling panels of adjacent modules, are combined by a laminating process during the modular assembly on site into one structural unit denoted as the doubled floor structure.
Structural components are designed substantially in a ribbed slab shape which offers following advantages:
1. The shape reduces the weight of the structure and the quantity of concrete mixture.
2. The shape lends itself to the most advanced method of manufacture of flat panels known today, i.e. to the method of hydraulic pressing.
3. Structural components, when combined into a doubled structure, create a cellular sectional profile which offers very conveniently a space for the distribution of mechanical equipment within the modular structure, such as specifically the electrical-signal conduits, thus eliminating the inconveniency of the embed ment of such an equipment during a process of the manufacture of panels.
In order to facilitate the distribution of conduits between horizontal and vertical components, flutes of the ribbed-slab structure are generally aligned.
Vertical pipes embedded in wall panels and vertical reinforcement bars are both used advantageously for vertical reinforcement of the structure and as well as dowels needed for the interconnection of components during the process of manufacture of modules. Moreover, lifting nuts welded inside pipes at the top, are used for the purpose of the attachment of the lifting frame.
DESCRIPTION OF THE PREFERRED EMBODIMENTS In order to simplify the matter, the invention deals only with the structural aspects of the construction of the building. Itis to be understood, that the structural enclosure of the building module, denoted as the modular structure, has to be complemented with all other parts of the building to become the building module,
which then constitutes the particular portion of the modular cluster, which is the substantial portion of the total building.
The applicability of the invention is demonstrated here on a simple example ofa building section consisting of3 bays and 3 habitable stories. Openings for stairwells, elevator shafts, plumbing chases, doors, windows, etc., the exterior enclosure of modules, balconies, terraces, roof parapets and similar features are not illustrated.
The coordinating system applied here in accordance with the related invention cited before introduces coordinating dimensions denoted as:
a. the modular height MH (FIGS. 2,3,8-10,17) which is eventually specified as the bottom-, intermediate-, topmodular height BMI-I, IMI-I, TMH;
b. the modular width MW (FIGS. 1,2,17);
c. the segmental depth SD of which a certain multiplicity, not less than 2 SD, constitutes the depth of the module (FIGS. 1,3,4,7,13-l7);
d. the modular depth MD (FIGS. 3,15,17).
The coordinating system governs also the disposition of connecting means, in this particular case represented by steel pipes l embedded in wall panels at distances D from SD-coordinates and at distances T from MW-coordinates (FIGS. 4,6,7,9,14-17).
The typical modular structure of an interior-bay intermediate-story building module is illustrated in FIG. 17. It consists of two wall panels, a floor slab and a ceiling slab. For structural reasons, as a rule, wall panels are manufactured as a one-piece panel. Horizontal slabs, however, as a rule will be divided in panels of which the width will be determined by the dimensional capacity of the manufacturing method. In most cases, the width of the floorand ceiling-panel will be equal to SD, some methods will allow for the width equal to 2 X SD, or more.
Wall panels are designed and manufactured substantially in the sectional profile denoted as the ribbed slab. The flat surface is oriented typically toward habitable space, thus a couple of wall panels between adjacent modules creating a doubled wall structure (FIGS. 4,8-10). In cases of the simple wall structure, typically, flat surface is oriented toward the exterior of the building and the ribbed interior surface is enclosed by panels 3 (FIGS. 7,12) eventually comprizing a layer of thermal insulation. For structural reasons, any portion of the section may be solid, such as around pipes, door openings, etc. Stiffening rims 5 (FIGS. 10, 12, 17,18) are provided at both top and bottom (FIG. 17), or, where manufacturing method does not lend itself readily to creation of both rims, such as the method of pouring in vertical batteries, the stiffening rim is provided only at the bottom of the wall panel (FIG. 18). Rims provide for larger bearing area and facilitate the application of the grout, so that the process of grouting can eventually be automated. Openings are located typically within SD distance which offers the advantage of uninterrupted vertical interconnection of the modular structure. Reinforcement bars 2 and pipes 1, both protruding at top and bottom of wall panels, function as vertical reinforcement of the building structure and simultaneously as dowels needed for the interconnection of modular structure. In addition, pipes with lifting nuts 20 (FIG. 19) welded near the top serve as connecting means for the structural interconnection of modules and simultaneously for the attachment of the lifting frame.
Floor and ceiling panels are similarly designed and.
manufactured in the sectional profile of a ribbed slab with flutes generally aligned with flutes of wall panels. Stiffening rims 4 (FIGS. 8,12,17) are provided at both wall ends in order to complete the wall panel for its final function as the vertical structural element. Holes 6, 7 (FIGS. 5,6,17) are provided at both rims, matching the position of pipes 1 and bars 2 of wall panels. In cases, where manufacturing method cannot produce stiffenning rims, such as the method of extrusion, the volume of rims is created by an additional fill 19 (FIG. 17) during the manufacturing process, or during the process of the assembly of the modular structure in the assembly jig.
The structural interconnection of the modular structure performed in the process assisted by the assembly jig, is secured by the adhesion of the epoxy grout 17 (FIGS. 5,6,10,12) applied on contacting surfaces between components, and by the bond between pipes and bars and the grout filling holes 6,7 (FIGS. 5,6).
Electrical-signal raceways are distributed within modular structure in spaces provided by flutes in all panels connected by notches 12 in floor and ceiling panels (FIGS. 13,17) and notches 13 in wall panels (FIGS. 10,12,17); by grooves (FIGS. 11, 17) in ceiling panels; by specially shaped holes 8 (FIGS. 11,17) in ceiling panels; and, where applicable, by vertical holes 9 (FIGS. 11,17) in the top stiffenning rim of wall panels.
The process of the lamination of the combined floorand ceiling panels into one doubled floor structure is accomplished during the process of the assembly of building modules in the following procedure:
1. Stopping strips 18 (FIGS. 12,13) are applied at the perimeter of the building structure on the top of modules at each story in order to prevent the grout 16 (FIGS. 5,6,8-10,12) from oozing out to the exterior.
2. Grout of suitable properties, such as the epoxy grout, is applied on the top surface of rims 4 of the ceiling panel and also within an adequate length on the top surface of ribs of ceiling panels.
3. Spacers of suitable material and the thickness equal to that of the connecting plates (if such hardware is used for the horizontal interconnection of modules) are distributed in the layer of the grout spread at wall ends.
4. The gravity of the upper module installed, distributes the grout uniformly, while spacers secure the necessary presence of the grout at any point of lamination.
Thermal insulation of floor and ceiling panels which are exposed to the exterior climate can be provided by two modes:
a. Exposed portions of horizontal slabs are made of concrete with the proper insulative capacity. If needed, an additional insulation 11 may be provided (FIGS. 14,16).
b. Conventional concrete is used and rigid thermal insulation is provided on top of such slab (FIG. 15). In the case of the projected slab, however, the exposed slab portion must be depressed in order to level the top surfaces of adjacent floor panels. The bottom floor panel (FIG. 16) usually does not require insulation because of the heated space below.
Electrical-signal raceways are installed during the process of the assembly and manufacture of building modules. Each module functions as a separately prewired unit. The electrical-signal interconnection between building modules is provided byspecial fittings 15 (FIGS. l0,1-3,16,17) applied during the process of 5 the assembly of the modular cluster on site. Such fittings are placed in accordance with particular conditions between junction boxes 14 (FIGS. '10,13,16,l7), in grooves 10 (FIGS. 11,17), and notches 12 (FIGS.
