Description

Monolithic module structure to build constructions and method for its manufacture
Field of the invention.
The present invention refers to methods and systems to build constructions, particularly to methods for the manufacture of construction modules that are integrated from a plurality of harnesses, and in conjunction with a flat roof, it is possible to build a great variety of constructions of the monolithic type, the dimensions, capacities and uses of these constructions are allowed to vary implementing in each module a plurality of panels. The field of application of the present invention is in regard to any construction, particularly constructions of prefabricated houses, classrooms and constructions with ample interior spaces, among others.
Background of the invention.
The traditional construction systems have distinguished themselves by creating edifications at the same place were they will reside through the gradual construction of diverse structural elements; however, these types of methodologies consume too much time, labor and their costs are too high. In this sense, the use of constriction processes for edifications using prefabricated elements, such as panels and diverse support structures that are subsequently assembled, represent superior alternatives, since they significantly reduce the existent inconvenients of the traditional construction systems. Traditionally, the construction systems for buildings of the prefabricated type, have agreed to manufacture modules coated with concrete, which supported on metallic structures or concrete pillars are used to replace the traditional walls built with thin wall and concrete or any other material of this type to cover empty spaces between flanks of the structural elements of the building. At the moment diverse solutions of construction systems from prefabricated elements and methods to obtain such are known.
Corredera1 describes a building construction system that combines traditional or non-structural construction with structural construction, whereby concrete is used in both walls and slabs. According to this system, a concrete slab serves as a foundation means and reinforced concrete structural pillars are arranged thereon. On the other hand, cover plates are used to produce the walls, based on a light concrete which is reinforced using electrically welded mesh. In addition, gypsum panels or similar ones are connected to the inner faces of the walls, thus defining the final finish of the interior walls. Furthermore, other panels of expanded gypsum are placed on the interior of the gypsum panels that are connected to the inner faces of the walls in order to provide thermal and acoustic insulation. Finally it is described that the gypsum panels or similar are also provided on the cover plates corresponding to the slabs and in this case, the panels are humidity proof and are used to form the apparent face of the ceilings. Another system that shows the limitations of the inventions in this field is described by Grace2 , in which convertible buildings and the methods for their production are divulged. Particularly this system refers to a building construction method that comprises the stages of the construction of a floor, the construction of the walls over the floor and above them the construction of the ceiling, where at least one of the walls contains at least one opening to pass though it. Likewise mechanic and electric internal connections are fixed at least alongside the floor, the walls, the openings and the roof on a predetermined route and are connected to the corresponding external connections. Another step is to cover the mechanic and electric internal connections with detachable adornments that assume the appearance of aesthetic or functional counterparts that are found in non-convertible apartments, in such a way that the mechanical and electrical routes are not perceived, but are always accessible to be transformed without having to demolish the floor, the ceiling or the walls.
However the described systems above do not eliminate the necessity to produce the majority of construction elements, such as walls or structural elements, on the site where the building will reside.
Another alternative to create edifications in less time is represented by the construction systems that create inhabitable modules prefabricated outside the site where buildings will reside, and which will be later transported from the factory to the construction site where they will be mounted and assembled. In this sense, OIesch3 describes modular transportable edifications created from diverse elements previously constructed within a factory, and which are assembled in the site where the building will reside. The edification is created by the assembly of one factory module that is joined to a reinforced foundations previously placed on the terrain, placing horizontal and vertical segments that are assembled on the module to create habitable spaces attached to the main module. In this case, all the construction elements are made with light material panels (for example wood) and are reinforced with fillings of dense materials to provide them with resistance.
De Quesada4 describes multi-floor edifications made by the assembly of diverse modules composed of floor and roof segments connected among each other through a plurality of vertically extended columns that are placed on the corners of the module, in such a way that the columns, as well as the floor and the roof have assembly means which permits to connect them with other modules of similar dimensions. Once the structure of the module has been made, the walls are manufactured placing panels of diverse materials, generally light, that permit to produce the complete module. Vicino5 describes modular monolithic construction structures made from demouldable molds made with rigid external matrices and internal inflatable and collapsible molds, allowing the molding of the module form. The modules are integrated with the application of a gypsum layer covered by a reinforcement steal fiber layer, which is formed over the exterior walls of the internal collapsible mold where the molding segments for doors and windows are temporarily placed.
Subsequently, over the settled layers of material the external mold is placed creating a space between this and the layers, the empty space is filled with cementing material that is submitted to a curing and drying process. Over the cured and dried surface obtained, panels of diverse materials (wood, for example) are placed in order to form the walls, which contain a layer of gypsum that permits the joining of the surfaces. Finally the obtained structure, fit with a roof, walls, doors and widows, is joined with a foundations slab previously formed to create the complete module. Hopkins6 describes modular prefabricated structures that can be assembled between each other to create edifications of various floors and storeys. The non monolithic modules are designed to vertically align themselves one above the other and are fit with assembly means to generate the building; in addition they are composed of a plurality of panels, which configure the habitable space of the edification's interior. The walls formed by semi-light materials, are assembled over a monolithic concrete slab to create the first edification level over which similar modules are placed later on.
Coday7 describes monolithic construction modules prefabricated with concrete composed of a vertical wall, a horizontal roof and a pair of support structures in the way of columns fixed to the roof and localized on the opposite side of the wall. Panels of diverse materials can be placed over the monolithic structure, as well as diverse systems to provide residence services. Such modules can be placed one above the other or else adjacent to each other to create diverse constructions.
The former systems allow the transport and assembly of the module at the edification residence site, with which the inconvenients of the traditional systems and of assembly of prefabricated structural elements are eliminated, despite that such systems have the inconvenient of using light materials for the walls, thus the residences formed by such modules have a reduced stability, are less durable and don't have a convenient structure for environments with extreme ambient temperatures.
It is thus desirable to rely on efficient construction systems that allow the creation of stable and trusted edifications from prefabricated elements such as modules, to build durable, flexible and easily transportable monolithic constructions, which at the same time represent structural and economic advantages.
Objectives of the invention.
One of the objectives of the present invention is to provide prefabricated construction modules whose functional and structural resistance characteristics allow the edification of monolithic constructions of long durability that fulfill the quality and security standards established for such constructions. Another objective of the present invention is to provide easily transportable prefabricated construction modules that can be used as structural elements for the generation of durable monolithic edifications, of great stability and that efficiently insulate the residences from the environment. Another objective of the present invention is to provide prefabricated construction modules for versatile constructions that may be combined among each other to generate multiple construction types according to the particular construction necessities.
Another objective of the present invention is to provide with a module fabrication method for monolithic constructions, from which modules are obtained whose functional and structural resistance characteristics allow the construction of long durable buildings that fulfill the quality and security standards established for such constructions.
Another objective of the present invention is to provide with a module fabrication method for monolithic constructions that allows the fabrication of such modules at high volumes and competitive costs. Another objective of the present invention is to provide with a module fabrication method for monolithic constructions whereby the obtained modules can be stored, transported and placed in a fast and easy way at the places originally conceived for each stage.
Even another objective of the present invention is to provide with a module fabrication method for monolithic constructions, so that through the obtained modules it is possible to construct buildings of creative and sustainable solutions for the necessities of an increasing and demanding society like ours.

Detailed description of the invention.
Contrary to the function of the modules known until today, which is reduced solely to their utilization as false walls, the present invention describes the creation of pre-constructed modules that are used as structural elements in a construction, from which and in all possible combinations with a plurality of interior panels used at convenience for space and functionality, define by themselves monolithic structures of construction, which can be easily transported, easily arranged on the conceived site for the construction of the edification, and that above all result in an option that is economic, fast in its process, and versatile, so as to adapt to the different construction necessities of the communities where it is implemented. The modules of the present invention provide a thermal and acoustic insulation to the residence, superior to the one obtained by traditional construction systems, at the same time they provide with structural stability and construction durability, which translates into security of the created edifications. To obtain the invention modules light cementing materials that also provide structural stability are used, allowing thus a substantial reduction in the weight of the manufactured modules making their transport and assembly at the construction site an easy task. Moreover, the modules can be manufactured in different sizes and assembled among each other, with which multiple combination options can be created to produce buildings of different applications, for example houses, classrooms, multiple use rooms, dinner rooms, community centers, additional bathroom modules, etc. The invention modules (figure 13) comprise a foundations slab (25) over which the module walls (23) are placed, the walls composing a single space between each other and are integrated into the foundations using union means fitted on the foundations (5). The module is completed assembling a flat roof slab (32) over the walls (23) using assembly means fitted on the walls and the flat roof (figure 22). Alternatively the module includes interior panels (21) manufactured with the same material as the walls and which can be placed to delimit specified habitable zones depending on the type of building. This configuration allows a more structural solidity of the edification and a greater versatility since the modules can be combined among each other. The modules can have openings for their functioning, such as doors (38) and windows (37) that are created while the module walls are being obtained. Likewise, the modules of the invention contain the necessary mechanic, electric, hydraulic and of gas elements allowing the subsequent installation of sanitary furniture and the use of electrical and gas appliances, depending on the designated use for the edification. For example, the modules can only contain sufficient electric and mechanic elements to create habitable spaces that do not require hydraulic or gas installations.
On the other hand, the characteristics of the invention modules allow the creation of habitable comfortable spaces that can be installed even in areas of extreme heat, as they efficiently isolate the residences from the outside temperature; in this case, the residence temperature is always maintained below the outside temperature in situations of high temperatures.
In relation to the finishes of the module, the internal and external walls, as well as the roof, these can be covered with diverse materials used by conventional finishes, for example gypsum, diverse outdoors resistant coverings or paintings depending on the necessities and specifications of the building required. In this case the finishes of the module are carried out according to the described invention method in one of the module manufacturing working stations.
The characteristics of the invention modules allow their transport and assembly at the edification residence site (figures 14 and 15), thus is not necessary to conduct there the interior and exterior finishes since they were conducted before their installation; likewise the placing of doors and windows is not necessary at the edification site, as they are previously placed and adjusted on the module that is going to be installed.
For effects of the invention, the dimensions of the modules can be those that prove to be convenient for the creation of standard habitable spaces required for each edification type and based on the valid construction norms. However, the advisable module dimensions are comprised between 4 to 8 meters in width and between 3 to 4 meters in length. This allows multiple module combinations, for example combinations of 2 to 6 modules of the same dimensions or of different dimensions, with which edifications can be created that have habitable spaces of at least 21 to 150 m2 depending on the requirement of the edification. To transport the invention module in an easy way, the module has simple fastening elements fitted on the foundations and the flat roof that allow to hold it in its place (figure 13). The module fastening elements found on the foundations (8) are aligned with fastening elements localized on the flat roof (27), in such a way that fastening means can go across them, for example a band (33) or sling of resistant material, and surrounds the entire module from its inferior part so that their extremes remain arranged on the superior part of the module (figure 15). The extremes of the fastening means that have remained on the superior part of the module are fastened to heavy feed mechanisms to be deposited later in load vehicles (figure 14) and to be transferred in a safe way to the place of the construction (figure 15).
For effects of the invention, the modules can be obtained by the following stages
I. Manufacture of harnesses,
M. Manufacture of sub-modules,
I IlMl. Manufacture of flat roof and interior panels, IV. Integration of the interior panels into the sub-module,
V. Assembly of flat roof over the sub-module walls, and
Vl. Transport and storage of the finished module. During the harness manufacture stage, the necessary harnesses for the fabrication of sub- modules, interior panels and flat roofs are manufactured; such harnesses are classified according to their use in structural, electrical, hydraulic, sanitary and of gas. Depending on the type of edification required, the use of hydraulic, sanitary and gas harnesses is optional, the size of these is also optional depending on the size of the desired module.
In the sub-module fabrication stage, the foundation over which the exterior module walls (23) will be created is fabricated (figure 5). During this stage a monolithic structure is created by the walls composing a single piece between each other and foundation (figure 11). The walls are integrated into the foundations using union means previously fitted on the foundations (5). The foundations are created using a mold adjustable in size (6) where the diverse harnesses (1 , 3, 4, 7), depending on the type of edification to be obtained, as well as the union means (5) posterior to the module walls are placed. Over the described arrangement a high resistance cementing material, for example hydraulic cement, is added (figure 6) retiring the foundations mold (6) when the cementing material has settled. Over the foundations obtained (25) an internal mold adjustable in size (11) is placed (figure 8 and 9). The necessary harnesses for the walls (15), as well as the molds for doors (17), windows (16) and wall holes (vanos) are put over this mold, subsequently an external mold adjustable in size (18) is placed over this structure, with which a space between this and the internal mold (11) is formed (figure 10). This empty space is then filled with high resistant and light-weight cementing material (19), retiring the internal (11) and external (18) molds when the added cementing material has fully settled.
In relation to the stage of interior panels (21) and flat roof (32) manufacture, this is carried out simultaneously to the sub-module manufacturing stage, creating the flat roof and the interior panels if they are required for the edification. In case of needing the interior panels, these are integrated into the sub-module to delimitate the habitable spaces of the edification (figure 21). The interior panels (21) are obtained in a similar way as the module exterior walls (23), using exclusively a mold adjusted to the appropriate dimensions to generate an empty space that is subsequently filled with cementing material. With respect to the flat roof (12), this is obtained using a mold adjustable in size (26) where the diverse harnesses (29, 30), depending on the type of edification to be obtained, as well as the union means posterior (figure 22) to the module walls are placed. As well as for the foundations (25), a high resistance cementing material is added over the mold (28), obtaining thus a flat roof slab when the cementing material has settled.
Subsequently the flat roof (32) is assembled over the sub-modules walls (23) using union means localized on the walls and on the flat roof (figure 22), with which the monolithic module is created (figure 13). The module is submitted to conventional internal and external wall finishing processes, waterproofing of walls and roof, placement of doors, windows, and the required electric, hydraulic or gas appliances.
When the invention module is finished, it is stored and transported (figure 14) to the site where it is going to be placed. At the site minimal terrain leveling and delimitation tasks are carried out where the module or modules required for the desired edification and in accordance with the architectonic project are going to be placed (figure 15). In one of the embodiments of the invention, the modules contain reinforcement columns (61) that are localized at the extremes of the site where one module is joined to the other (figure 37). The columns (61) are preferentially added to the invention modules when these are used to create buildings with ample habitable spaces that don't necessarily have interior panels to delimit the habitation zones, for example when using several 3 X 8 m sized modules that are assembled among each other to create classrooms or community centers. In this case, the flat roof slab (32) of this module type has an integrated beam (66) localized in the area where one module is going to be joined to the other (figure 42), in such a way that it functions as a structural reinforcement of the monolithic flat roof slab (32) that will be then placed over the module walls (23). For these types of assemblies, the existence of flat roof beams (66), as well as reinforcement module columns (61), allow the creation of a monolithic structure of high resistance and durability.
To create modules that have columns and beams on the flat roof, the next manufacturing method is followed.
I. Manufacture of harnesses,
II. Manufacture of sub-modules, III. Manufacture of flat roof and columns,
IV. Integration of the columns into the sub-module,
V. Assembly of flat roof over the walls and columns of the sub-module, and
VI. Transport and storage of the finished module.
The stages I and Il of this method are carried out in the same way as the general method described beforehand.
With respect to the stage of flat roof (32) and column (61) manufacture, this is carried out simultaneously to the sub-module manufacturing stage (II). The columns (61) are obtained form internal and external molds of specified dimensions; over the internal mold (11) a structural column harness fitted with union means to the walls and the foundations is placed (figure 33 and
39), next the external column mold is placed over and an empty space is formed that is subsequently filled with high resistance cementing material, for example hydraulic concrete. When the cementing material has settled, the internal and external molds are retired, obtaining thus a column (61).
The flat roof (32) is obtained using a mold adjustable in size (26) where the diverse harnesses (29, 30), depending on the type of edification to be obtained, as well as the union means posterior (figure 39) to the module walls are placed. During the fabrication of the flat roof slab (32) a beam (66) is placed to reinforce the integrity of the flat roof slab (32), the beam (66) is going to interact directly with the columns (61) for the final assembly of the module (figure 33). Over the flat roof mold the high resistance cementing material is added (28) obtaining a flat roof slab when the cementing material has settled.
Subsequently the columns (61) are placed over the foundations (25) resting on the walls (23). The column-foundations-walls union is carried out by the elements of union contained in these elements (figure 41). When the columns (61) are installed, the flat roof (32) is assembled over the sub-modules walls (23) using union means localized on the walls and on the flat roof (figure 39), with which the monolithic module is produced. Finally the module is submitted to diverse conventional internal and external wall finishing processes, waterproofing of walls and roof, placement of doors, windows, and the required electric, hydraulic or gas appliances. The finished module or modules are stored and transported then (figure 14) to the site where they are going to be placed. At the site minimal terrain leveling and delimitation tasks are previously carried out and in accordance with the corresponding architectonic project.
In any of the methods described to obtain the invention modules, the union of each of the module elements is carried out using union means localized in such elements, if possible the union is made by welding since such union means are preferably steal plates build onto specific sites of the structural harnesses that are part of elements of the module. This allows the creation of monolithic solid structures which will translate into the creation of structurally resistant and durable buildings. In relation to the union of several modules to create the edification, this is carried out using union and metallic fastening modes that permit to join the module (figure 38) by retouching the space that may exist between each other with cementing material, on the interior as well as on the exterior of the edification. Likewise the part of the module which is coupled with other modules has union means that allow the joining to other module by welding. The invention method is basically carried out using a plurality of working stations that interact between each other to separately generate the diverse elements that constitute the invention module, such elements are obtained simultaneously and in series consequently allowing an increment in the production of modules of interest. As it can be appreciated in figures 1 to 4, diverse manufacturing units constituted at the same time in working stations are distinguished in compliance with the elements that are produced in them.
- The harness manufacturing unit (figure 1 and 3) is dedicated to the production of the required harnesses for the creation of modules, - The panel manufacturing unit (figure 1 and 3) is dedicated to the fabrication of interior panels, flat roofs, and columns, and is constituted by stations of: production of flat roofs (station F), production of interior panels (station G), curing of flat roof and interior panels (station H) and transportation of flat roof and interior panels (station I) (see figure 2). In one of the embodiments of the invention the panel manufacturing unit is constituted by the stations of flat roof and columns production (station F and G), curing of the flat roof and columns (station H) and transportation of roof top and columns (station I) (see figure 4),
- The module manufacturing unit (figure 1 and 3) is dedicated to the fabrication of invention modules constituted by the stations of: internal mold preparation (station A), production of foundations (station B), production of sub-module (station D), and assembly and finishing of the module (station E) (see figure 2 and 4),
- The manufacturing unit for the fabrication of cementing material or concrete factory (figure 1 and 3) is dedicated to the obtaining of cementing materials that will be used for the fabrication of modules, this unit provides concrete of high resistance, for example hydraulic concrete, in the stations of. production of foundations (station B) and flat roofs (station F) (figure 2), while in one of the embodiments of the invention it provides the same type of concrete to production stations of flat roofs and columns (station F) (figure 4), and provides concrete of high resistance and low density to production stations of sub-modules (station C) and production of interior panels (station G) (figure 2 and 4), and
- The storage unit dedicated to the storage of concluded modules (figure 1 and 3). From this zone, the modules are packed and prepared for their transport by heavy load vehicles, for example load vehicles equipped with platforms, to the construction residence area. Within the invention module, diverse elements that constitute the monolithic module can be distinguished. The module will be subsequently installed at the construction site combining or not other modules of similar dimensions and characteristics to create the desired edification.

The cellular concrete referred to in the different stages of this fabrication method, is a type of concrete with anhydrous calcium sulfate or anhydrite base and Portland cement, this cement does not present the undesirable effects associated to construction materials that use calcium sulfate, at the same time this cement develops high resistance to compression, conserving low volumetric weights that allow to use them as convenient cellular materials for the construction industry. Because of the high compression resistance that these type of cellular concretes develop, these can be used as light construction materials and at the same time constructive projects are provided with all the advantages that cellular materials can offer, because these also possess the common properties that characterize them. However, for effects of the present invention any other cellular concrete can be used that provides high resistance to compression so that it can be used as structural material in the construction; it is preferable to use the improved cellular material compositions described by Prieto Gomez8, this materials develops high resistance to compression (≥110 Kg/cm2) and convenient volumetric weights (>1200 Kg/m3), the cellular composition is basically a mixture of the following elements:
1. A cementation agent constituted by a mixture of a) Portland cement or of clinker of Portland cement and b) Anhydrous calcium sulphate,
2. Silica sand,
3. Polyester fiber,
4. Foaming additive, and
5. Water reducing agent. The method of the present invention offers diverse advantages that are mainly reflected in the significant reduction of execution time to build diverse constructions, in the reduction of labor used and in the reduction of costs, during the construction as well as on the final building, without lowering the quality of buildings obtained, which comply with the quality and security standards established for themselves. In addition, the method described here permits to obtain, at high volumes, modules for monolithic constructions that can be used afterwards for any type of construction, let it be for a complete building, an extension or used for remodeling. For example, if various working stations that form part of the present invention process are operated at the same time, a significant quantity of modules can be generated in sequence to supply the current demand for new houses. On the other hand, the production of modules at high volumes for construction allows that these can be offered to the construction industry at very competitive prices.
In this sense, the module fabrication process of the present inventions allows a production capacity of up to one module per hour, which under a working structure of 3 shifts permits to obtain up to 24 modules per day leaving the last stage of the manufacture. This taken to a continuous process of placement in the field allows putting 8 houses of 2 modules each per day. Each of these houses requires around 1 week for the completion of connections and exterior details for it to be in possibilities of being inhabited; this depends on the speed of terrain preparation where the houses are going to be placed and on the speed of the constructor to finish the exterior details and all the connections of the building. Because of the former, the process of the present invention allows to significantly reduce the fabrication time of any building in at least a 50 % in comparison to the time invested in the traditional fabrication process to generate the same buildings. For example, if houses of two modules are generated with the invention process it is possible to obtain them in a 4 weeks average; whereas the generation of the same edifications with the traditional edification method results in an 8 weeks average.
As a way to illustrate the present invention, the following examples are presented, but these by no means limit the reach of the invention. Example 1. Obtaining of construction for house from the combination of 2 modules of the invention.
Two modules of 3 X 5.5 mts were obtained according to the method of manufacture of modules described in the present application. In the unit of manufacture of harnesses (figures 1 and 2), diverse structural, electrical, hydraulic, sanitary and of gas harnesses were obtained (figure 18), as well as to obtain the slab of corresponding foundation with the purpose of obtaining the 2 sub- modules that are observed in figures 23 and 24. Submodule I is equipped with two interior panels assembled between in one of its ends to form a bathroom with access opening (figure 23), whereas sub-module Il does not have interior panels (figure 24). Sub-module Il counts on a left lateral wall equipped with an opening in arc form (figure 25), formed from the structural harness that is observed in figure 17; in the case of sub-module I1 the left lateral wall was obtained from the structural harness shown in the figure 19, which has integrated an electrical harness that allows to provide electricity to the interior of sub-module I. The interior panels of sub-module I were assembled to the wall (figure 20) and to the foundation slab (figure 21) by means of weld of the located plates of union in the interior panels, walls and foundation slab. Integrated the interior panels, the roof slab previously obtained, it was integrated to the walls and it holds by means of union equipped with rods that are inserted in the roof slab and insured by mechanical means (figure 22). The assembled modules were finished by means of sealed of the cementitious material and later application of textured coverings. Later the obtained modules were placed in a vehicle equipped with platform and transported to the site of positioning by means of the use of a crane and resistant bands that were placed in the grooves located in the foundation and roof slabs of each one of the modules (figure 25). The obtained modules were assembled in the positioning site, previous made level preparation of the land, by means of the joint and subjection by weld of steel plates placed in the site of union of the modules, filling up the possible empty spaces between the modules with normal cement. The house obtained by means of the combination of these modules is shown in figures 26 and 27. As it can be observed, the generated house is equipped with diverse delimited living spaces and the services necessary to living it.
Example 2. Obtaining of construction for scholastic classroom from the combination of 2 modules of the invention.
Two modules of 3 X 8 mts were obtained according to the method of manufacture of modules described in the present application. In the unit of manufacture of harnesses (figures 3 and 4), diverse structural and electrical harnesses were obtained, as well as the columns and the corresponding foundation slab with the purpose of obtaining the 2 sub-modules that are observed in figure 36. Submodule I is equipped solely with windows, whereas sub-module Il has windows and an access door to the interior. The frontal wall of sub-module I was obtained from the structural harness shown in figure 29, whereas the frontal, lateral and posterior wall from submodule Il they were obtained from the structural harnesses of figures 28, 30 and 31. As it will be able to be observed, the structural harness of the lateral wall of sub-module Il have an electrical harness that it allows to provide
5 electricity to the interior of sub-module II.
The roof slab was obtained from the structural harness shown in figure 32 equipped with grooves for its transport, placing a beam of roof and plates of union to the walls of the sub-module (figure
33).
The foundation slab (figures 34 and 35) was obtained from the structural harness shown in figure
10 35, equipped with cross-sectional beams (figure 36) and grooves for its transport.
Obtained the sub-module, the roof slab was assembled on the walls and held by means of union equipped with steel plates that were welded to each other (figure 39), whereas the roof beam was assembled on the columns of each module (figure 40) and assured by means of union equipped with rods (figure 41), allowing to good support and solidity of the structure of the
15 module. A lateral view of the obtained sub-module I can be observed in figure 42.
The assembled modules were finished by means of sealed of the cementitious material and later application of textured coverings. Later the obtained modules were placed in a vehicle equipped with platform and transported to the site of positioning by means of the use of a crane and resistant bands that were placed in the grooves located in the foundation and roof slab of each
20 one of the modules (figure 42). The obtained modules were assembled in the positioning site, previous made level preparation of the land, by means of the joint and subjection by weld of steel plates placed in the site of union of the modules, filling up the possible empty spaces between the modules with normal cement. The house obtained by means of the combination of these modules is in figures 43 and 44. As it can be observed, the generated house is equipped with
25 ample inner space and the electrical services necessary to use it.
Example 3. Fire proof test of the module walls
One of the module walls described in example 1 , as well as the walls manufactured with other construction materials were submitted to a fire proof test exposing the external faces of the walls
30 to a source of heat during different time intervals according to norm NMX-C-307-1982. As it can be observed, the temperature of the external and internal walls was recorded and was graphed as a function of exposure time. As figure 45 shows, the side of all the walls exposed to the source of heat registered a temperature of in between 800 to 1 ,2000C, while the non-exposed side registered various temperatures depending on the type of the wall material (figure 46). In the
35 case of the invention module wall (figure 46), the side not exposed to the fire registered the lowest temperature of all materials, reaching a maximum temperature of 600C with the highest exposure time. This contrasts with the temperature reached on the side of the wall exposed to the fire in the same time interval (close to 1,3000C). In contrast with the behavior of the invention module walls, the walls elaborated with traditional construction materials, like concrete or block, reached temperatures above 1000C on the side not exposed to the fire.
Example 4.Thermal test of module walls. The diverse wall materials tried out in the abovementioned example were submitted to a thermal test measuring the thermal conductivity K of each one of the materials (BTU in/ ft2 Fh). As figure 47 shows, the invention module wall (A series) turned out to be the most thermal of the materials by observing the lowest thermal conductivity value, while at the hydraulic concrete wall (E series) a complete different behavior was observed by registering the highest conductivity values. The rest of the materials registered significantly greater values than the observed for the walls of the invention module.
Example 5. Obtainment of diverse edifications with the invention modules
Different sized modules were obtained according to the module manufacture method described in the present application. In accordance with the architectonic process of interest, the modules were placed and assembled at the construction residence site to grate varied edifications. To create houses, individual modules measuring 3 X 7 m or 3 X 8 m equipped with interior panels, were used to create habitable spaces of 21 to 24 m2 (see figures 48 and 49), while diverse combinations of 2 modules of the same dimensions with interior panels (see figure 27 and 50) were used to create habitable spaces of 33 to 36 m2. In the same way two modules of different dimensions with interior panels were combined to create habitable spaces of 36 to 39 m2 (figure 51 and 52), while the diverse habitable spaces in between 49 a 57 m2 (figure 53) were obtained combining 3 modules of different dimension with interior panels. As it can be observed the obtained houses include all services and are ready to be inhabited. 5 On the other hand 2 to 6 modules of 3 X 8 m were combined to create ample diverse habitable spaces for assorted uses. As it can be observed in figures 54 to 58, the combination of these modules created edifications that can be uses as classrooms for schools, dinner school rooms, mass media halls, community centers, and school bathrooms. In some cases the modules have interior panels (see figure 55, 57 and 58) that can be included into the module according to the 0 corresponding architectonical project.
