Description

CONSTRUCTION SYSTEM AND METHOD WITH CONCRETE FORMS MOLDED IN THE BUILDING ITSELF

[001] The invention belongs to the field of civil construction. More specifically, the present invention deals with a system and method that uses forms to create massive structural walls of concrete. In other words, the walls are concreted with the help of forms that are assembled in loco according to the architectural project. The present invention shows the construction of two blocks of a building, however, the same construction system and method can be used for the construction of more blocks of a building.

State of the Technique

[002] The system and method of forms and accessories provide less physical effort for workers and greater productivity of the work compared to existing solutions in the state of the art.

[003] Construction systems and methods that use formwork through cast-in-place concrete walls are already known and performed in the state of the art.

[004] The monolithic concrete panels cast in loco have been used in Brazil since the 80's, and can be used in single-storey and multi-storey buildings (IPT, 1998).

[005] In this system, a set of formwork and frame is used, with the concrete being introduced between the forms to form the walls of the building.

[006] This constructive system has developed and is being increasingly used in works of varying standards and in taller buildings, which in some cases reach 30 floors (MISURELLI; MASSUDA, 2008).

[007] In view of the housing deficit and the need to meet the growing demand for housing, mainly, but not limited to those of social interest, the present invention was conceived.

[008] Thus, the present invention provides a faster system and constructive method than those existing in the state of the art and with great cost reduction. Furthermore, the present invention provides for the reduction of the physical effort of the workers and allows the transport, at the same time, of several internal formwork panels of the apartments.

[009] The present invention provides the lifting of the entire set of internal panels already assembled, which leads to a saving of time and resources. In the present invention, in a second stage, there is the execution of the slabs, comprising a set solidarized between a concrete slab on site and an immediately lower level previously built (precast) and hoisted into place with mechanical lifting equipment, including but not limited to cranes, cranes, munck, telescopic handler, among others.

[0010] The system and construction method taught here is advantageously flexible and allows several internal walls to be executed after the execution of the slabs, where they can be built with sealing masonry in concrete blocks, ceramic, plasterboard or similar. These internal walls do not have a structural function and due to the cost-benefit ratio they are preferably made of drywall or plasterboard, providing even more efficiency to the work.

summary of

[0011] The present invention then teaches a constructive system that comprises one or more forms of concrete walls molded in the building itself, comprising a foundation, preferably a raft or strapping or piled slab on which a reinforcement of the concrete walls is mounted. of the building. A plurality of one-piece internal panels are positioned inside the building and a plurality of one-piece external panels are positioned outside the building, configuring one or more forms, which comprise the reinforcement inside.

[0012] The armature of the present invention should be interpreted broadly. Here the reinforcement is not restricted to structural steel reinforcement. Thus, in the present invention, for example, fiberglass can also be used in place of structural steel. Therefore, the term reinforcement here encompasses the use of steel, fiberglass, carbon fiber, aramid, or any synthetic fiber or structuring medium. Thus, the term reinforcement can be additionally interpreted as any synthetic fiber inserted in cement matrices, including but not limited to filaments with diffuse distribution, fabrics, yarns, blankets, screens, among others.

[0013] The formwork is filled with concrete creating the molded concrete walls of the building. In particular, the system comprises an expansion configuration and a retraction configuration. In the expansion configuration one or more blanking panels are coupled adjacent to an internal one-piece panel configuring a formwork to be filled with concrete and form the molded concrete walls of the building. In the retraction configuration, one or more stripping panels are uncoupled from the internal solid panels, and the internal solid panels are still coupled together forming a hoisting assembly by means of lifting equipment.

[0014] The invention also teaches a constructive method by means of one or more forms of concrete walls molded into the building itself, where a foundation (radier or strapping or piled slab) on which a reinforcement of the concrete walls of a first block of the building is mounted.

[0015] A plurality of solid internal panels are positioned inside the building and a plurality of solid external panels are positioned on the outside of the building configuring one or more forms, which comprise the reinforcement inside. The formwork is filled with concrete forming the molded concrete walls of the building. The present method particularly comprises an expansion configuration where one or more stripping panels are coupled adjacent to an internal one-piece panel configuring a form to be filled with concrete and form the molded concrete walls of the building. The present method further comprises a retraction configuration, where one or more stripping panels are uncoupled from the internal solid panels, the internal solid panels still being coupled together forming a hoisting assembly by means of a lifting equipment.

[0083] The present invention deals with a constructive system that comprises one or more forms (11) of concrete walls molded in the building itself, comprising a foundation (1) on which a reinforcement (2) of the concrete walls of the building, whereby a plurality of internal solid panels (4) are positioned inside the building and a plurality of external solid panels (8) are positioned outside the building, configuring one or more forms (11).

[0084] The term reinforcement should be interpreted here in a comprehensive way including steel, vibro fiber, carbon fiber, among others that will produce the same or similar effect identified by a technician in the subject.

[0085] Inside the forms there is a reinforcement (2), and the formwork (11) is filled with concrete (10) covering the reinforcement (2) forming the concrete walls molded in the building that has a structural function. In particular, the present system has an expansion configuration and a retraction configuration.

[0086] In the expansion configuration, one or more stripping panels (5) are coupled adjacent to an internal one-piece panel (4) configuring a formwork to be filled with concrete (10) and form the molded concrete walls of the building.

[0087] In the retraction configuration, one or more stripping panels (5) are uncoupled from the internal solid panels (4), and the internal solid panels (4) are coupled together forming a hoisting set by means of a lifting equipment. the equipment of lifting may exemplarily be a crane or cranes or munck or telehandler or any other lifting means recognized as equivalent by one skilled in the art.

[0088] In an exemplary way, the foundation (1) consists of a raft equipped with a plurality of recesses where the reinforcement (2) is erected. The foundation (1) may alternatively be a strapping or a piled slab or equivalent recognized by a person skilled in the art. In addition, one or more aligners (6) are also provided on the surface facing the interior of the building of the internal solid panels (4). The aligners (6), in addition to their main function, which is to align the internal solid panels (4), assist in the structuring of said panels when they are in the retracted configuration. During the lifting of the sets, there are great mechanical efforts and the aligners (6) also help with the structural issue when lifting the set to the subsequent block.

[0089] In said retraction configuration, one or more stripping panels (5) are coupled to the internal one-piece panel (4), the stripping panels (5) being hoisted together with the set formed by the internal one-piece panels (4) coupled between yes. This feature of the invention brings even more efficiency to the work, as the main parts needed to carry out the expansion configuration are transported or hoisted together. That is, advantageously, the stripping panels (5), the squares (7), the stripping panel aligners (61) and the internal solid panel aligners (6) are transported together to a next block, in order to which are subsequently applied in the expansion of the internal solid panels (4). This makes the constructive system even more efficient and advantageous.

[0090] Even more specifically, still in the retraction configuration, one or more stripping panels (5) are still coupled transversally to two or more aligners (6) arranged horizontally on the internal one-piece panel (4), the stripping panels (5) being hoisted together with the set formed by the internal solid panels (4) coupled together.

[0091] In order to make it more efficient and reduce the effort of workers, the movement for coupling and uncoupling the internal solid panels (4) is carried out by means of a trolley (12).

[0092] In the expansion configuration, in the corners formed between the stripping panels (5) or between a stripping panel and an internal solid panel (4) squares (7) are coupled. It is possible in the expansion configuration, to have any configuration of the corners, for example, the corners can be formed between the stripping panels (5) and an internal solid panel (4) or between two internal solid panels (4) or between two stripping panels (5). The squares are attached in the corners and serve for the alignment of the internal panels as well as to assist in the structuring of said panels for the lifting of the same for the next block.

[0093] In the expansion configuration, in a portion configured by the meeting of a stripping panel (5) at the center and two adjacent internal solid panels (4) are coupled aligners (61). Said aligners (61) in the retraction configuration can also help with the structural issue and are transported with the set, bringing even more efficiency to the work.

[0094] In the retract configuration, pedestals (13) are used to support the internal solid panels (4). These pedestals are another resource that helps the worker by making their activities simpler, reducing physical effort and bringing productivity gains to the work.

[0095] To achieve the retraction position, the internal solid panels (4) are coupled together by means of telescopic forks (14), forming a hoisting set.

[0096] The present invention also teaches a constructive method by means of one or more forms (11) of concrete walls molded in the building itself, where a foundation (1) is made on which the reinforcement (2) of the walls is mounted. of a first block (31) of the building, whereby a plurality of internal solid panels (4) are positioned inside the building and a plurality of external solid panels (8) are positioned outside the building, configuring one or more forms (11).

[0097] The forms comprise the reinforcement (2), and the form (11) is filled with concrete (10) covering the reinforcement (2) forming the molded concrete walls of the building. In particular, the method comprises an expansion configuration where one or more stripping panels (5) are coupled adjacent to an internal one-piece panel (4) configuring a formwork to be filled with concrete (10) and create the molded concrete walls of the edification. The constructive method also comprises a retraction configuration where one or more stripping panels (5) are uncoupled from the internal solid panels (4), with the internal solid panels (4) still being coupled together forming a hoisting set by means of an equipment of lifting.

[0098] The external solid panels (8) and internal solid panels (4) are transported to the work preferably by a truck. Panels (8) and (4) are unloaded from the truck and placed in their respective positions by means of mechanical lifting equipment (a crane or cranes or munck or telescopic handler or other equivalent lifting means). These panels are heavy and the transport by means of mechanical lifting brings productivity and saves the worker from efforts. Thus, workers only manually position the stripping panels (5) which are lighter due to their size. [0099] In the present method, one or more aligners (6) are mounted on the surface of the internal solid panels (4) facing the interior of the building. As already mentioned, these aligners (6) also have a structural function when the set of internal solid panels (4) is retracted.

[00100] In the retraction configuration, one or more stripping panels (5) are still coupled to the internal one-piece panel (4), with the stripping panels (5) being hoisted together with the set formed by the internal one-piece panels (4) coupled between itself, making the constructive method taught here even more practical.

[00101] In the retraction configuration, one or more stripping panels (5) are still coupled transversally to two or more aligners (6) arranged horizontally on the internal one-piece panel (4), the stripping panels (5) being hoisted together with the set formed by the internal solid panels (4) coupled together.

[00102] The movement for coupling and uncoupling the internal solid panels (4) is carried out preferably by means of a trolley (12) reducing efforts and bringing more comfort to workers.

[00103] In the expansion configuration in the corners formed between the stripping panels (5) or between a stripping panel and an internal one-piece panel (4), the squares (7) are coupled. The squares (7) ensure the preferably perpendicular alignment between the forms, guaranteeing the alignment of the walls.

[00104] In the expansion configuration, the aligners (61) are coupled in an exemplary configured portion by meeting a stripping panel (5) in the center and two adjacent internal solid panels (4).

[00105] In order to facilitate and reduce the physical effort of workers, pedestals (13) are used to remove the internal solid panels (4). The pedestals (13) support said internal solid panels (4) almost perpendicularly to the ground, having a small angle.

[00106] In the retraction configuration, the internal solid panels (4) are coupled together forming a hoistable assembly by means of telescopic forks (14). The telescopic forks (14) make the union between the internal solid panels (4) and are responsible, together with the aligners (6) (61) and squares (7) for structuring the set of panels to be lifted. That is, in the retraction configuration, the internal solid panels (4) are coupled together by means of squares (7) and by aligners (61) and the squares (7) and aligners (61) are hoisted together with the set of panels internal solid blocks (4), in order to facilitate the expansion work in the other block. [00107] After filling the forms with concrete (10), that is, after concreting and curing the respective concrete of the walls of a first block (31), the internal solid panels (4) are deformed and immediately configured in the position of retraction. At this moment, the reinforcement (2) of a second block (32) of the building that corresponds to the room configurations of the first block (31) is prepared or is already prepared. After coupling the internal internal panels (4) to each other, forming a set, said set is lifted by means of a mechanical lifting equipment (crane or cranes or munck or telescopic handler, among others) to be positioned in the corresponding room of the second block (32).

[00108] In the present invention, the word room does not actually refer to the final room of the building, since the divisions of the final rooms are carried out by non-structural walls such as dry wall or plasterboard after the installation of the slabs. Thus, the room to which the invention refers is a part of the housing unit with walls that have a structural function and, therefore, are more easily standardized between the blocks of a building.

[00109] In the present invention, each housing unit is exemplarily formed by two sets of internal integral panels (4). However, a plurality of sets of internal solid panels (4) can be used to form a housing unit or even only one set of internal solid panels (4) can be used to form a housing unit.

[00110] The word blocks must also be interpreted in a broad way, as it can refer to blocks of the same building, of a neighboring building or any other equivalence evident to a technician in the subject within the spirit of the invention.

[00111] Thus, the invention is described and claimed with the construction of at least two blocks. However, it is evident to a person skilled in the art whether or not the construction of more than two blocks is simultaneous, it being evidently within the spirit of the invention the obvious modification of the present methodology for construction of three, four or more blocks including steps for the construction of more blocks. That is, it is obvious to a technician in the field, for example, to adapt the present methodology for the construction of more than two blocks on a first floor, where the steps of contraction and retraction would be repeated until the construction of the first floor was completed and, next, the construction of the floor immediately above and so on until completing the desired number of floors.

[00112] Thus, after the retraction to form the set of internal solid panels (4) of each room of the first block (31), the set is hoisted and transferred to the respective room of the second block (32). After positioning the set of internal solid panels (4) in the room, the panels (4) and (5) are put back in the expansion configuration.

[00113] After transferring the sets of internal solid panels (4) from the first (31) to the second block (32) one or more guardrails (15) are installed in the upper portion of the external solid panels (8) of the first block (31) and, after transferring the sets of internal solid panels (4) from the first (31) to the second block (32), the external solid panels (8) of the second block (32) are positioned.

[00114] After installing the guardrails (15) in the upper portion of the external solid panels (8) of the first block (31) a mechanical lifting equipment (crane or cranes or munck or telescopic handler) positions the pre-slabs (16 ) covering the first block (31). After positioning the pre-slabs (16) in the first block (31), the guardrails (15) of the second block (32) are installed.

[00115] After at least the guardrails (15) of the first block are installed, the slab cover (17) and the walls of the second block (32) are concreted. That is, the insertion of concrete (10) in the formwork and above the pre-slab (16) occurs simultaneously. This makes the work even more efficient as it reduces steps. In other words, concrete is added to the formwork to create the walls of the building and concrete (10) is added over the pre-slab (16) forming the slab cap (17). The pre-slab (16) and the slab cover form the structural slab of the building.

[00116] After concreting and curing the slab cover (17), the external solid panels (8) of the first block are deformed and work platforms (18) are mounted in the place where the external solid panels (8) were removed. Concomitantly or not, the reinforcements (2) are installed on the slab cover (17) of the first block (31) for the construction of an immediately higher floor.

[00117] After assembling the work platform (18) the respective one-piece external panel (8) is hoisted together with the respective guardrail (15) to the floor immediately above. After (or concomitantly) the assembly of the one-piece outer panels (8) on the upper stage, the one-piece inner panels (4) of the next lower stage in the second block (32) are placed in the retracted configuration. Subsequently, the retracted internal panel assemblies (4) are transported by means of any lifting means (for example, a crane or cranes or munck or telescopic handler) to be positioned in the corresponding rooms on the floor immediately above in the first block ( 31).

[00118] After the transfer and positioning of all sets of internal solid panels (4) retracted on the floor immediately above the first block (31), said sets are expanded. Concomitantly or not to the subsequent stage, the pre-slabs (16) are transported and positioned in order to cover the floor immediately after in the second block (32). After covering the pre-slabs (16) in the second block (32), the walls of the first block (31) and the slab cover (17) of the second block (32) are concreted.

[00119] After curing the concrete (10) the deforming and retraction of the sets of internal solid panels (4) is carried out on the walls of the first block (31) and concomitantly or not with the assembly of the reinforcements (2) of the wall of the second block (32). After the assembly of the wall reinforcements (2) of the second block (32) and the retraction of the sets of internal solid panels (4) on the walls of the first block (31), said sets of internal solid panels (4) are transferred from the first block (31) to the corresponding room in the second block (32) on the same floor.

[00120] An example of embodiment of the invention is shown by means of the sequence of attached figures. Figure 1 shows the construction of a foundation (1) of the state of the art, in this exemplary form a raft, on which a first block (31) and a second block (32) will be erected in an exemplary way.

[00121] Figure 2 shows the installation of the reinforcement (2) by a worker on the foundation (1) of the first block (31). Figures 3 and 4 show the continuation of the reinforcement installation (2).

[00122] Figure 5 shows the completion of the installation of the reinforcement (2) in at least one room of the building, which already allows the positioning of internal solid panels (4). Said internal one-piece panels (4) are transported to the work by a truck that is positioned close to the building being built. A crane lifts said panels and transports them inside the reinforcement (2), as shown in figure 6.

[00123] After positioning one or more internal solid panels (4) inside the reinforcement (2), the workers assemble the aligners (6) to structure the internal solid panels (4), as shown in figures 7 and 8 .

[00124] Figures 9 and 10 show the movement of the internal solid panels (4) by a worker using a cart (12). The worker then takes the internal solid panels (4) to the reinforcement (2), this being a first step in the expansion of the set of internal solid panels (4).

[00125] Figures 11 and 12 show the assembly of the stripping panels (5). These panels are lighter and can be transported by workers with or without the help of the trolley (12). [00126] Figure 13 shows the assembly of the squares (7) and deform aligners (61) with a continuation of the expansion step of the internal solid panels (4). Figure 14 shows the assembly of the stripping panels (5) and their view from the external part of the work showing details of the reinforcement (2) and the foundation (1).

[00127] Figure 15 shows the assembly by the workers of the aligners (61) and also shows the assembled squares (7). These steps are part of the expansion configuration of the internal solid panels (4).

[00128] Figure 16 shows the arrival by truck of the external solid panels (8), their lifting by means of a crane (not shown) and the positioning on the external part of the armature (2). The window negatives (9) transported by truck are also shown. The window negatives (9) are fixed by the workers to the external solid panels (8), as shown in figure 17.

[00129] Figure 18 shows the assembly from another angle of the external solid panels (8). Figure 19 shows the positioning of the last one-piece external panel (8). The internal solid panels (4) together with the external solid panels (8) constitute the wall forms (11). The reinforcement (2) is located inside the molds. Figure 20 shows the forms of the first block (31) ready to receive the concrete (10).

[00130] Figure 21 shows the concreting of the walls of the first block (31), that is, the filling of the forms with concrete (10). The methodology taught here is very agile and efficient. From the beginning of the assembly of the reinforcement (2) on the foundation (1) until the concreting of the first block is preferably done in one working day.

[00131] On the second day, after concreting and total or partial curing of the concrete (10) the demoulding of the panels begins, that is, internal solid panels (4) and deforming panels (5), starting the retraction configuration, as shown in figure 22. In this step, the squares (7) and aligners (61) are removed from the stripping panels.

[00132] In figure 23 a worker is shown moving an internal one-piece panel (4) with the cart (12). The internal solid panel (4) is now recessed from the wall to perform the retract configuration. When moving the internal one-piece panel (4) away, they are supported on pedestals (13) to prevent tipping, as shown in figure 24. All work is performed with less effort for workers, resulting in greater well-being and efficiency for The work.

[00133] Figure 25 shows the structuring of the internal solid panels (4) through the aligners (61), the same used for the alignment of the stripping panels (5) in the position of expansion. In this retraction configuration, the aligners (61) have the function of helping in the structuring and joining of the internal solid panels (4). In order to facilitate the transport to another block, the stripping panels (5) are coupled to the internal solid panels (4). The stripping panels (5) are preferably fixed on the aligners (6).

[00134] Figures 26 and 27 show two workers performing the retreat of the internal solid panels (4) by means of the carts (12).

[00135] Figures 28 to 33 show an important step in the retraction of the internal solid panels (4), the installation of the telescopic forks (14) which are a structuring component of the set of panels that will later be lifted by a mechanical lifting equipment . The squares (7) and the aligners (6) and (61) complete the structuring of the internal solid panels (4).

[00136] Figure 34 shows four apartments (housing units) of the first block (31) with all internal solid panels (4) retracted and structured. Subsequently, each housing unit will receive drywall type walls for the internal division of housing units. In this system, the dry wall can be mounted after the slab is completed.

[00137] Figures 35 and 36 show that the reinforcements (2) of the second block (32) have already been assembled. In both figures, the lifting by means of a crane of a set of internal solid panels (4) structured for transport to the second block (32) is shown. Figure 37 shows the positioning of the set in the second block (32). Figure 38 shows the arrival of another set of internal solid panels (4) to form a housing unit in the second block (32). In this exemplary realization, each housing unit is formed by two sets of internal solid panels (4).

[00138] Figure 39 shows that all sets of internal solid panels (4) were transported from the first block (31) to the second block (32). This figure also shows the beginning of the expansion of the internal solid panel sets (4) in the second block.

[00139] As was done in the first block (32), the external solid panels (8) are lifted by means of a mechanical lifting equipment, as shown in figure 40.

[00140] Figure 41 shows the positioning of the last external solid panel (8) of the second block (32) and the installation of the guardrails (15) in the first block (31). The system and method of the present invention is very efficient, because in the construction sequence taught here, there is a possibility for a group of workers to develop concomitant activities in both blocks (31) and (32). [00141] After installing the guardrails (15), the lifting and positioning of the pre-slabs (16) in the first block (31) is started, as shown in figures 42 and 43.

[00142] Figure 44 shows the pre-slabs (16) completely positioned on the first floor of the first block (31). Figure 45 shows the simultaneous concreting of the slab cover (17) of the first block (31) and of the forms (11) of the second block (32). That is, the concreting operation is used to carry out simultaneous concreting in both blocks with substantial gains in the process. In an exemplary way, with this concreting stage shown in figure 45, the work of the second day ends.

[00143] In an exemplary way, the third day of work begins with the removal of the external solid panels (8) Concurrently, the reinforcement (2) is mounted on the first floor of the first block (32) and the work platforms are installed, as shown in figure 46. The external solid panels (8) can be supported on the pedestals (19), as shown in figure 47. The external solid panels (8) are raised together with the respective guardrail

(15), as shown in figure 48.

[00144] Figure 49 shows the lifting of the last one-piece external panel (8) and the completion of the installation of the armature (2) in the first block (31). Preferably concomitantly, the set of internal solid panels (4) are retracted in the second block (32).

[00145] Figure 50 shows a top view of the work with all internal solid panels (4) retracted in the second block (32). Figure 51 shows the lifting of the first set of internal solid panels (4) from the second block (32) to the first floor of the first block (31).

[00146] Figure 52 shows the positioning of the first set of internal solid panels (4) in the first block (31). The sets are being transported until all the sets of internal solid panels (4) are positioned in the first block (31), as shown in figure 53.

[00147] Figure 54 shows the expansion of the sets of internal solid panels (4) on the first floor of the first block (31) while the pre-slabs are positioned

(16) in the second block (32).

[00148] Figure 55 shows the side view of the work in the first block (31) showing a worker on the work platform (18) and the guardrail (15). Figure 56 shows the pre-slabs (16) completely installed in the second block (32) and the sets of internal solid panels (4) completely expanded in the first block (31). [00149] Figure 57 shows the concreting of the slab cover (17) in the second block (32) and the concreting of the walls of the second floor of the first block (31). The concreting marks the end of the third day of work.

[00150] The fourth day of work begins with the assembly of the reinforcement (2) in the second block (32), the retraction of the sets of internal solid panels (4) of the first block (31) and the elevation of the external solid panels ( 8) to the upper floor, as shown in figure 58.

[00151] Figure 59 shows the transport of the sets of internal solid panels (4) from the first block (31) to the second block (32). Figure 60 shows the transport and installation of the pre-slabs (16) for the coverage of the second floor of the first block (31) and the expansion of the internal solid panels (4) of the second block (32). Figure 61 shows the steps of figure 60 completed.

[00152] Figure 62 shows the concreting of the slab cover (17) and the walls of the first block

(31), ending the fourth day of work.

[00153] Figure 63 shows the elevation to the upper floor of the external solid panels (8) together with the guardrail (15) and the work platform (18) in the first block (31), marking the beginning of the fifth day of work. Furthermore, figure 63 also shows the contraction of the internal solid panels (4) in the second block (32). Note that neither the guardrail (15) nor the work platform are decoupled from the external solid panels (8), making the constructive method quite efficient.

[00154] When lifting the external solid panels (8), it is preferably carried out concomitantly with the installation of the reinforcement (2) of the third floor. Preferably concomitantly, the internal solid panels (4) are retracted on the second floor of the second block

(32), as shown in figure 64.

[00155] After retracting the internal solid panels (4) of the second block (32), they are transferred to the upper floor of the first block (31), as shown in figure 65. The pre-slabs (17) are installed on the second floor of the second block (32) and preferably concomitantly, the internal solid panels (4) of the first block (31) are expanded, as shown in figure 66. Figure 67 shows the completion of the step shown in figure 66. After At this stage, the building is ready to receive the concrete (10) and form the slab cover (17) of the second block (32) and the walls of the upper floor of the first block (32), ending the fifth day of work .

[00156] It is noted that the construction methodology of the building is repeated alternating the steps between blocks (31) and (32) for the construction of a plurality of upper floors. That is, the methodology can continue to be used to build as many floors as desired, within the structural limits of the building design. Thus, many floors of a building can be erected quickly, efficiently and with little physical effort on the part of workers, in addition to no loss of construction materials.

[00157] Modifications to the methodology in order to expand the number of blocks or floors within the spirit of the invention are considered obvious to one skilled in the art. Likewise, changes to some steps of the methodology that may occur simultaneously or not or occur in a different order or sequence are considered obvious to a person skilled in the art, within the spirit of the invention.
