Description

 "CONSTRUCTION PROCESS OF ARMED CONCRETE COUPLINGS"

FIELD OF THE INVENTION This application is directly related to the Construction industry in general. Specifically related to the technical field of the processes for the construction of warped reinforced concrete roofs that obey the surface of the hyperbolic paraboloid.

BACKGROUND OF THE INVENTION

In the state of the art related to the Construction Industry and more specifically with the processes for the construction of warped reinforced concrete roofs, the following patent applications and granted patents were found, cited in order of importance and similarity:

• Mx / a / 2012 / 00S127 "CONSTRUCTION OF ARMED CONCRETE SAILINGS WITHOUT CIMBRA" whose Applicant is Patricio Antonio Pérez Tenorio Amaro, filed on April 20, 2012 and describing a construction process of "watch over" reinforced concrete Without form, this process is not new, since it has been part of the state of the art for at least four years, this information can be verified in electronic media. In addition, "velarías *" is a term that is coined with tensile structures, that is, structures that are constructed with pipes, cables and pre-stressed canvas, never with reinforced concrete, so the term is poorly applied.

In this application, a series of steps are described so that, with the help of wire rod and fine steel mesh (prevents concrete runoff), reinforced concrete roofs can be constructed without the need for formwork, since the mesh functions as such. So in practical terms this process does use formwork, because the mesh has that role.

This process presents great disadvantages in its application, since it is limited to simple forms due to the low maneuverability and difficulty in the arrangement of the wire rod and the mesh, complicating the obtaining of a surface that obeys the of the hyperbolic paraboloid and complicating its application on roofs with a greater degree of architectural and constructive difficulty. This leads to longer construction times, which translates into a significant increase in costs. My invention, on the other hand, solves this disadvantage greatly, since the wide manageability of a lamp allows to obtain many architectural forms and accommodations that result in greater aesthetics and structural safety of the roof.

Another of the disadvantages that this process presents is that by not effectively tensing the wire rod, it tends to present deformations that prevent the formation of the surface of a Hyperbolic Paraboloid being this, very important for its work by form and thus avoiding, efforts of flexion. The foregoing translates into low structural safety since, as the desired shape is not obtained, efforts may arise that present future problems. My invention solves this disadvantage, since once the desired shape is obtained with Lycra, it is stiffened, with the help of a resin and glass fiber, thus obtaining a formwork that cannot be deformed and this guarantees the surface of the Paraboloid Hyperbolic.

• Mx / a / 2010/007687 "APPLIANCE AND METHOD FOR THE REPLACEMENT OF A BRIDGE USING PRE-MOLDED CONSTRUCTION TECHNIQUES" whose Applicant is Paul Westley Porter, filed on July 14, 2010 and describing a method and apparatus to replace a bridge that includes steel piles, concrete decks and runners. This request is directed towards the specific field of bridges and the roofs described in this application, they have nothing to do with warped roofs in the form of Hyperbolic Paraboloid, since it uses flat roofs.

• Mx / a / 2012/004149 "UNFORGETTABLE SECTIONS FOR PREFABRICATION OF PARABOLIC BRIDGES OF ARMED CONCRETE" whose Applicant is Elias Pérez Tenorio, filed on March 22, 2012 and in which they are described prefabricated with Hyperbolic Paraboloid forms that when resistant by form they allow a better transmission of the requested loads, this coupled with the manufacture of parts with similar characteristics makes the connections more rigid. This request is obviously within the technical field of bridges and does not solve the problems that my invention solves, since said invention is limited to the manufacture of simple prefabricated products and not to the shapes and configurations that my invention can. In addition to my invention is aimed at solving problems in the field of warped reinforced concrete roofs, which allow to cover patios, garages, parks, pavilions, etc. • Mx / a / 2011/005990 "FABRIC SIDING STRUCTURE AND MANUFACTURING METHOD OF A FABRIC SIDING STRUCTURE * whose Applicant is Uio Systems LLC, filed on June 6, 2011, describing a series of steps to manufacture structural pieces joining sheets of flexible fabric The description comprising said application uses flexible sheets of fabric or "geotextiles" that by their simple designation usually have a higher cost than my process uses, in addition to the technical field of said This application is related to the construction of structural elements such as; Beams, Columns, Trabes, etc. Therefore, this request is different from my invention, since the use of "geotextiles" is actually to replace conventional wooden formwork for straight elements, not so with concrete covers with warped surface, what my invention does.

In the usual literature it is possible to find written about the existing methods and systems for the construction of reinforced concrete roofs, an example of this is what Juan Ignacio del Cueto Ruiz Funes writes in his decalogue "Felix Candela, the magician of the shells of concrete. " Article published in Arquine, international architecture magazine, no. 2, Mexico, winter 1997.

The process that Candela used was to manufacture the formwork in situ, by means of wooden slats that when placed in relation to guidelines and generatrices, previously assembled, the shape of the Hyperbolic Paraboloid was obtained. However, this process is highly expensive, tedious and complicated, which translates into competitive disadvantages and low profitability of the work.

OBJECTIVES OE THE INVENTION

Another objective of the present invention is to provide a construction process that saves time and reduces costs in the construction of reinforced concrete roofs with warped surfaces.

A further objective of the present invention is to provide a reinforced concrete roof with Hyperbolic Paraboloid surface.

In a very general way the present invention consists of a construction process of warped reinforced concrete roofs that includes the following stages: 1) Construction of structural supports; The supports can be columns, insulated footings, concrete dies, walls, steel profiles, slabs, beams, beams and other known structural elements (concrete or steel) that have sufficient strength to receive the stresses transmitted by the concrete decks. armed. 2) Mounting a support frame: The support frame is composed of a support structure (polines, stability bars and fasteners) and the frame (stringers). Said elements may be previously manufactured with steel profiles or manufactured in situ with wooden structure, the joining of said elements may be with known means, among which are included; screws, nuts, rivets, pins, staples, nails, etc.

3) Mounting a Lycra fabric: Since the support frame has been assembled, the Lycra fabric is fixed to the frame with the help of known means, including; screws, nuts, rivets, pins, staples, nails, etc., depending on the material used in the support frame (wood or steel). The Lycra fabric should be fixed maximum at every 10 centimeters over the length of each of the support frame stringers and should be stretched to the maximum. To get the warped shape, the Lycra must be stretched to the maximum, always trying not to tear or break it.

4) Rigfdizar or harden the Lycra fabric with resin and fiberglass: In order for the Lycra fabric to support the weight of the concrete, it is necessary to stiffen or harden it, so polyester resin and fiberglass resin are used to harden Lycra fabric with the form it has previously acquired. The form that the Lycra fabric takes is under our design and control, so that a formwork that guarantees the desired shape and the hardness sufficient to contain the concrete without deforming is obtained. Subsequently, burnt oil or release agent should be applied to the formwork to prevent the concrete from sticking to the formwork. This action is optional, as the formwork can remain on the site as part of the structure, in which case it will not be necessary to apply either burnt oil or release agent. Having done the above, the formwork is ready.

5) Mounting the fencing frame: Once the Lycra fabric is mounted and stiffened, a fencing frame should be placed that consists of the placement of bars that delimit the surface of the roof to be built and whose function is to prevent runoff of concrete. For this, bars are placed on the perimeter of the stiffened Lycra fabric and fixed on the stringers, making a kind of sandwich and fixed to the stringers with the help of known means, among which are included; nails, screws, nuts, rivets, pins, staples, etc. 6) Place you armed to base da rods and wire rod: Once the formwork is ready, proceed to mount a perimeter rods that are attached and fixed to some anchor rods. The perfmetral rods have the function of supporting the edge forces that appear on the warped concrete decks. Once the perimeter rods are mounted, a steel grid is placed that serves as reinforcement of the concrete. The steel grid is constructed strip by strip with wire rod and the annealed wire ties are tied, the grid enters the anchoring area and the perimeter rods can be used welding to ensure greater strength. As an extra reinforcement, it can be superimposed on the formwork and under the steel grid, a steel mesh or fabric, which gives greater resistance to the roof.

7) Empty concrete: Whenever you have placed the steel reinforcement (perimeter rods and steel grid) a concrete mixture is prepared, you must ensure that the mixture is somewhat dry, in order to work better. The concrete used can be conventional (sand, gravel, cement and water) or translucent concrete, as well as transparent resins. Once the concrete mixture is ready, it is emptied into the formwork and must be rounded, supervising that the entire thickness of the casting is at least 6 centimeters, then it must be taped so that the concrete is compacted. The concrete must be allowed to set at least 15 days before removing the formwork.

8) Remove the formwork and give final finishes: Once the concrete has set, the formwork is removed and the usual finishes are given (reworking, polishing, painting, weather protection, etc). Finally the area is cleaned and the concrete cover is finished. As mentioned earlier, the formwork can be part of the structure, so that its removal is optional.

DETAILED DESCRIPTION OF THE INVENTION

The process for the construction of warped reinforced concrete roofs whose characteristics and problems that are presented are clearly shown in the following section and are detailed in detail with the help of the accompanying illustrative figures.

The main characteristics of this construction process are: a) Cover resistance to tension and compression stress. b) Great manipulation of the final shape of the roof. c) Reduction of construction times. d) Reduction of labor. e) Reduction of material used. f) The final construction is monolithic. g) Industrially applicable in housing complexes and urban developments. h) Long life of the roof. 0 Low construction cost. j) Useful in the entire range of architectural configurations and designs.

The technical problems that are in the state of the art is that the existing processes require many maneuvers to get complicated warped shapes, not always obtaining these. In addition to the fact that the construction of concrete roofs with existing processes entails many risks during the construction of the same, because when no form is used in one of these processes, there is a risk that the final roof does not work by shape, this that is, there are bending efforts and this puts the structure at risk. Another one of the problems that exist is the high cost of building a reinforced concrete roof using some of these construction processes, since some of them use a formwork whose assembly is complicated and expensive, which translates into a long time construction and a great cost of the work.

The solutions provided by the present invention are:

• Reduction of the construction time of a concrete roof.

• Considerable reduction in construction costs.

• Great manageability of the surface shape. • Conception of roofs with a high degree of architectural difficulty.

• Great structural security.

Next, the best way of carrying out the invention is described, by means of the figures, in order to be able to show more clearly said invention. For this, the following description will be divided into two modalities:

• Modality 1: Describes the construction process of an insulated roof. That is, a cover that has been conceived as a unique structure and whose supports are only intended to support it.

 • Modality 2: Describes the construction process of a continuous roof. That is, a roof that is built from existing structures and that serve to anchor and support the roof. The examples shown to illustrate the stages of the construction process of both modalities, objects of the present invention, do not limit at all the countless architectural configurations and designs that can be constructed with the present invention, so the examples shown They are just some of the many architectural designs.

MODALITY 1. The first part that should be conceived is structural support. Figure 1 shows the structural supports, in this case columns (1), which serve to displace the roof. The columns (1) are constructed in a conventional manner and are reinforced with a castle made up of steel bars (rods) and rings, the steel bars are called anchor rods (2) and their function is to anchor the offset of the cover. In Figure 1 it can be “appreciated that the rod of ajeje (2) is uncooked in the upper part of the column (i), this is so because at least 45 centimeters should be left free that serve to subsequently the perimetral rods (13), tat and overlap and anchor as shown in Figure 7. Although columns (1) are used in this example, the cover can be displaced from the ground level, using concrete dies. The roof can also be displaced from other known structural elements, including; trabes, steel profiles, beams. footings, pillars, etc., provided that these have been designed to support the roof and have sufficient strength to receive the efforts transmitted by it. For reinforced concrete elements that are used as supports, the anchor rods (2) must be left at least 45 centimeters for overlapping with the perimeter rods (13). If the structural elements used as supports are made of steel, the perimeter rods (13) are welded to said elements. In the event that the roof is displaced in existing elements, the steps described in Modality 2 must be followed.

Since the structural supports are built, the support frame is placed. The support frame is made up of two structures; the support structure (polines (3), stability bars (4) and fasteners (6)) and the frame (stringers (5)). Figure 2 shows the placement of the support frame. For this, the fasteners (6) are first placed at the upper ends of the columns (1), the fasteners (6) are fixed to the columns (1) with the aid of known fixing means, including; nails for concrete, thymes, pins, wire, etc., this is illustrated in greater detail in Figure 3a and 3b. Once the fasteners (6) have been fixed to the columns (1), polines (3) are placed according to the design, figure 2. The polines (3) are fixed to the ground with known fixing means, between the which are included; nail them directly on the ground, fix them with the help of stakes and nails, fix them with a steel base that is screwed to the ground, etc. Subsequently the polines (3) are stabilized with stability bars (4) which, a) Like the polines (3), are fixed to the ground with the known fixing means, which gives them great structural safety. In addition, the connection between the polines (3) and the stability bars (4) is made with the known joining means, among which are included; nails, staples, rivets, screws, pins, wire, etc. Next, one end of the beam (5) is placed on the fastener (6), figure 3a, and the other end of the beam (5) is fixed on the top tip of the pollen (3) with the aid of known fixing means, between those that are included; nails, screws and nuts, pins, staples, wire, rivets, steel plates, etc., the above can be seen in Figure 2. The relationship between fasteners (6) and stringers (5) is that of ensure the stability of the beam (5) through its rest on the fastener (6), the above is illustrated in Figures 3a and 3b. In addition to the fact that the fastener (6) has flanges that prevent lateral sliding of the crossbar (5) and this guarantees greater structural stability of the support frame, the above is also illustrated in Figure 3b. The relationship between the stringers (5) and the polines (3) is that of transmitting the roof loads to the polines (3) while the concrete sets. It is worth mentioning that the structural elements of the support frame; Fasteners (6), polines (3), stability bars (4) and stringers (5), can be manufactured with wooden structure (boards, planks, bars, struts, sheets, blocks, etc.) or with steel structure (sheet, bars, profiles, plates, floor, channels, etc.). Figure 3b shows the use of some of the materials such as wood and steel profiles in the conception of support frame elements.

Once the entire support frame (fasteners (6), polines (3), stability bars (4) and stringers (5)) has been mounted, a review of its stability is made on site, this, to guarantee the security of the temporary structure. This review consists of the inspection of each and every one of the unions of the elements that make up the support framework.

Once the structural safety of the support frame has been checked, the lycra fabric (7) is placed, which together with the resin (10 and 12) and the glass fiber (11) form the cover formwork. In figure 4, the assembly of the Lycra fabric (7) can be seen. For this, the Lycra fabric (7) is fixed to the stringers (S) maximum at every 10 centimeters over the length of each of the stringers (S). That is, if the length of the crossbar (5) is two meters, there should be at least twenty fixing points between the Lycra (7) and the crossbar (5). To fix the Lycra fabric (7) to the stringers (5) known fixing means are used, including; nails, staples, rivets, pins, screws and nuts, etc. Between each of the points to be fixed, the Lycra fabric (7) should be stretched to the maximum, this, to obtain a uniform wrinkle-free surface, but supervising that the Lycra fabric (7) does not tear or break. The Lycra fabric (7) is fixed in each and every one of the stringers (5) that conform the perimeter of the support frame, always stretching the Lycra (7) to the maximum to obtain the warped surface. It is pertinent to mention that the Lycra fabric (7) must be continuous, that is, it must be a single piece of fabric that covers a certain area, in order to obtain a regular surface, although it is possible to join or sew pieces of Lycra fabric (7) covering large areas, as the Lycra fabric (7) allows to cover large spaces thanks to its elasticity.

Once the Lycra fabric (7) has been placed and the shape of the architectural design of the roof has been obtained, the Lycra fabric (7) is stiffened or hardened to Get the formwork. Lycra (7) is stiffened or hardened with the aid of resin (10 and 12) and fiberglass (11). Figure 5 shows the application of the resin (10 and 12) and the fiberglass (11). First of all the polyester resin (10 and 12) must be prepared with the help of a catalyst (provided by the manufacturer), this to regulate the fast setting of the resin. Having done the above, a first abundant layer of polyester resin (10) is applied to the surface of the Lycra fabric (7), this with the help of a paint brush. Pieces of fiberglass (11) (previously cut into pieces) are immediately placed on the resin layer (10) that has been applied to the surface of the Lycra fabric (7). Once the entire Lycra surface (7) has been covered with the fiberglass pieces (11), a second layer of resin (12) is applied on the layer formed by the fiberglass pieces (11) . These layers help the Lycra fabric (7) to obtain a considerable stiffness or hardness and thus serve as a formwork. It should be monitored that the second round of resin layers (12) fully moisten the fiberglass (11), to ensure continuity in the rigidity of the formwork. Lycra (7), in conjunction with resin (10 and 12) and fiberglass (11) form the formwork. The curing time of the polyester resin (10 and 12) is a function of the amount of catalyst recommended by the manufacturer. The first resin layer (10) has the function of hardening the Lycra fabric (7). While the fiberglass (11) and the second resin layer (12) has the function of increasing the strength of the formwork. The number of resin layers (10 or 12) can be between two and seven, that is, there must be at least two resin layers (10 and 12). While the number of fiberglass layers (11) can be between one and six, that is, there must be at least one fiberglass layer (11). Figure 10b shows the application of three layers of fiberglass (11) and four layers of polyester resin (10 or 12), being within the limits described above. The limits described are for material saving purposes only, as each person can apply the number of layers of resin (10 0 12) and fiberglass (11) they want. The above serves to increase the thickness of the formwork, always starting with a layer of resin (10) on the Lycra (7) and then a layer of fiberglass (11), then another layer of resin (12) on the fiber of glass (11) and the layers alternate; resin (10o 12), fiberglass (11), resin (10 or 12), fiberglass (11), thus completing the desired number of layers and taking care that it is always finished with a resin layer (10 or 12 ), to moisten the fiberglass (11) and make it harden, tai and as illustrated in figure 10b. The above offers greater thickness and at the same time greater resistance to formwork.

Once the layers of resin (10 and 12) and fiberglass (11) have completely dried, the enclosure frame that is made up of fencing bars (8) is assembled. Figure 6 shows the fencing bars (8) that have the function of preventing concrete runoff. Once the Lycra tit (7) has been fixed to the stringers (5) and has been stiffened with the help of the resin (10 and 12) and fiberglass (11) layers, we proceed to fix the fencing bars (8) on the periphery of the stiffened Lycra fabric (7) and on the stringers (5) making a kind of "sandwich" between the stringer (5), the stiffened Lycra (7) and the fencing bar (8), this is seen in Figure 6, in which you can see the fencing bars (8) on the periphery of the formwork. The fencing bars (8) are fixed with the help of known means, among which are included; d a vos, wire, pins, screws and nuts, rivets, staples, etc. The fencing bars (8) must have a minimum fencing height of ten centimeters. The fencing frame (composed of fencing bars (8)) must be fixed over the entire support frame, specifically on the stringers (5), in order to enclose the surface of the roof to be constructed, figure 10a. The fencing bars (8) can also be manufactured with a wooden structure (boards, planks, bars, struts, etc.) or with a steel structure (sheet, profiles, channels, etc.).

At the same time or after the mounting of the enclosure frame, the upper bending (9) of the structural supports is installed, in this case of the column (1). Figure 6 shows the bending (9) that is given to the top of the column (1). Said bending (9) is arranged in a kind of drawer. The function of this bending (9) is to be able to cast the final part of the column (1) (where it displaces the roof), thus obtaining a monolithic union between the column (1) and the roof to be constructed. The formwork (9) of the upper part of the column (1) can be manufactured with a wooden structure (boards, planks, sheets, etc.) or with a steel structure (sheet, plates, screed, etc.). In the event that the supports are steel elements, a kind of drawer must also be built on the support that effectively transmits the efforts of the roof. Once the fencing bars (8) have been assembled and fixed, the upper bevel (9) of the column (1) and the resin layers (10 and 12) have completely dried and the rigidity of the formwork, we proceed to place the perfmetral rods (13). In figure 7, the walk of the perimetral rods (13) with the anchor rods (2) can be seen. The joint between the anchor rods (2) and the perimeter rods (13) must have a minimum overlap of 40 centimeters, this to ensure continuity. The perimeter rods (13) consist of a package of at least two rods of minimum number four. The connection between the perimetral rods (13) and the anchor rods (2) can be done with the aid of known joining means, including; welding, annealed wire ties, bends, etc. In the same way, the connection between perimetral rods (13) can be done with said known joining means. The perimetral rods (13) have the basis of resisting edge stresses, typical of warped reinforced concrete roofs, therefore it is the recommendation made before.

Once the perimeter rods (13) have been placed, the steel grid (14) is formed, which is made up of wire rod strips, double strips of annealed wire or electro-welded mesh. Figure 8 shows the assembly of the steel grid (14). The steel grid (14) is constructed on site, with the help of X * wire rod (a quarter of an inch) or with double strips of recoded wire. Each strip of wire rod is fixed at a maximum of every ten centimeters over the length of each of the perimeter rods (13), this with the help of known fixing means, including ios; welding, annealed wire bends, ties, etc., obtaining a kind of electro welded mesh. The moorings of the crossings of the reticle (14) are made with the help of mooring means, including condo; annealed wire, bends, welding, etc. The total surface area of the roof to be constructed must be covered and the anchoring of the steel grid (14) must be checked in each and every one of the perimeter rods (13). If annealed wire is used for the fabrication of the steel grid (14) double strips of recoded wire must be placed for each wire rod that is replaced. In addition, electro-welded mesh can be used for the steel grid (14), but it must be supervised that the mesh acquires the shape of the cover, so that it is inside the concrete casting. Once the steel grid (14) has been assembled and fixed, the concrete mixture (15) is made. The concrete mixture (15) can be prepared with known structural fillers, among which are included; sand, gravel, granite, conventional cement, mortar, translucent concrete, transparent resin, water, catalysts, etc. The concrete used to fill the formwork can be conventional concrete, translucent concrete or transparent resins. The concrete mixture (1S) must be manageable but always looking for something "dry *, to prevent its runoff. Whenever the concrete mixture (15) is ready, it is emptied into the surface of the formwork, as shown in figure 9. It must be rounded in order to monitor that it has a minimum thickness of 6 centimeters, in addition to making sure that it covers the entire steel grid (14), as it represents the reinforcement of the roof, the concrete must then be taped so that it is compacted, Figure 10a shows the stiffened Lycra fabric (7) with the help of resin layers (10 and 12) and fiberglass (11). it shows how these are fixed to the stringers (5), so it is also possible to observe the placement of the fencing bars (8) on the already stiffened Lycra (7) and the stringers (5). The anchor rods ( 2) and the perimetral rods (13), as well as the assembly of the re steel ticle (14) anchored on the perimeter rods (13). Finally, the layer of the concrete mixture (15) can be observed.

The concrete mixture (15) must be allowed to set at least 15 days before removing the formwork mold (Lycra (7), resin (10 and 12) and fiberglass (11)), if desired , or you can choose to leave it as part of the structure. However, if the formwork (Lycra fabric (7), resin (10 and 12) and fiberglass (11)) is to be part of the roof, wax or release agent should be applied on the stringers (5 ), so that the formwork does not stick to the stringers (5). Subsequently, the finishes of rigor (resanado, polishing and painting) are given and a finished cover (16) is provided, as illustrated in figure 11. in which the finished cover (16) is shown.

 MODE 2

In this modality, the structural elements that could be the possible supports of a roof must first be identified, in Figure 12 you can see a property in which it is planned to build a roof. In Figure 12, a slab (17) and a room constructed based on walls (18) can be identified, these structural elements are ios that will serve to illustrate this example.

 Once the structural elements that will support the roof have been identified, they are prepared to serve as an anchor and the roof is monolithic with them. In this example, the slab (17) being formed by a grid of steel bars will serve to displace the roof. Specifically, the rods that make up said grill serve well as anchor rods (2), because in these, the rods can be anchored (13) that absorb the edge forces. To be able to anchor the perimeter rods (13) to the anchor rods (2) of the slab (17), it is necessary to demolish the cutting edge per meter! of the slab (17) as shown in figure 13, in addition the edge of the roof that is glued to the wall (18) must be anchored to it, for this it is also necessary to scratch the joint area between the wall (18) and the cover so that there is some adhesion between both elements, figure 13. To carry out the demolition of the perimeter edge of the slab (17) and to scratch the joint area in the wall (18) the help of known means of demolition and scratching, including; chisel, mallet, hammer, hammer, screwdrivers, etc.

 In Figure 13 it can be noted that in (a junction area between the wall (18) and the roof there are holes, these are called anchor holes (19) and their function is to allow the anchoring of loading rods (21) and of the perimetral rods (13) as can be seen in Figure 17. The anchoring holes (19) can be made with the aid of known means, including: drill, broken hammer, chisel, mallet, plateau, etc.

Whenever the supports where the cover will be displaced have been prepared, a support frame is assembled comprising: the necessary fasteners (6), as well as the stringers (5), which in this modality have been divided into two types, wall stringers (5a) and free stringers (Sb). The wall stringers (Sa) are mounted along the lower bed of the junction area between the wall (28) and the cover, figure 14. Its function is to be able to fix the fabric of the wall (7) to it , since it is much easier to fix the Lycra fabric (7) to the wall beam (5a) than to the wall (18) directly, although the option of fixing the Lycra fabric (7) directly to the wall (18) is not ruled out, So it is also considered as an optional step. The mounting of the fasteners (6) on the wall (18) and slab (17) is done with the aid of known fixing means, including ios; nails, screws, pins, wire, etc. The mounting of the wall beam (Sa) is done with the aid of known fixing means, among which are included; nails, screws, pins, wire, etc. The assembly of the free crossbar (5b) is done by placing one of the ends on the fastener (6) that is in the wall (18), which, as described in MODE 1, the fastener (6) prevents the sliding of the free crossbar (Sb). The other end of the free spar (Sb) is leveled with the bottom of the slab (17) and fixed with the aid of known fixing means, including; wire, nails, pins, thymes, etc., the assembly of the mentioned elements can be seen in figure 14.

 It can be seen in figure 14 that it is necessary to form e! perimeter edge of the pit (17) in order to recover the demolished part, for this purpose a form (20) of the demolished perimeter edge must be placed, which will also serve to fix the Lycra fabric (7). The formwork (20) of the demolished perimeter edge is fixed to the slab (17) with the aid of known fixing means, including; nails, pins, screws, wire, etc. The fasteners (6), stringers (Sa and Sb) and the formwork (20) of the demolished perimeter edge can be manufactured with a wooden structure (boards, planks, bars, struts, etc.). ) or with steel structure (sheet, profiles, channels, etc.).

Once the fasteners (6), stringers (Sa and Sb) and the formwork (20) of the demolished perimeter edge have been assembled, the lamp (7) is assembled together with the resin (10 and 12) and the fiberglass (11) make up the cover formwork. In figure 15, the assembly of the Lycra fabric (7) can be seen. For this, the Lycra fabric (7) is fixed to the stringers (Sa and Sb) and to the formwork (20) of the demolished perimeter edge, maximum at every 10 centimeters over the length of each of said elements, that is, if the length of any stringer (5a or Sb) is three meters, there must be at least thirty fixing points between the Lycra fabric (7) and the crossbar (Sa or Sb). To fix the Lycra fabric (7) to the stringers (5a or 5b) and to the formwork (20) of the demolished perimeter edge, known fixing means are used, including those included; nails, staples, rivets, pins, tomos and nuts, etc. Between each of the points to be fixed, the Lycra (7) should be stretched to the maximum, this, to obtain a uniform wrinkle-free surface, but supervising that the Lycra (7) does not tear or break. The Lycra fabric (7) is fixed in each and every one of the stringers (Sa or 5b) and in all the periphery that conforms the formwork (20) of the perimeter edge demolished, always stretching the Lycra (7) to the maximum to obtain the warped surface, figure 15.

Once the Lycra (7) has been assembled and the shape of the architectural design of the roof has been obtained, the Lycra fabric (7) is stiffened or hardened to obtain the formwork. Lycra fabric (7) is hardened with the help of polyester resin (10 and 12) and fiberglass (11). Figure 16 shows the application of the resin (10 and 12) and the fiberglass (11). First, the polyester resin (10 and 12) must be prepared with the help of a catalyst (provided by the manufacturer), this to regulate the speed of setting of the resin. Having done the above, a first layer of polyester resin (10) is applied to the surface of the Lycra fabric (7), this with the help of a paint brush. Pieces of fiberglass (11) (which has previously been cut into pieces) are immediately placed on the first layer of resin (10) that has already been applied on the surface of the Lycra teia (7). Once the entire Lycra surface (7) has been covered with the fiberglass pieces (11), a second layer of resin (12) is applied on the fiberglass pieces (11). These layers help the Lycra (7) to obtain considerable rigidity and thus serve as a formwork. It should be monitored that the second resin layer (12) fully moisten the fiberglass (11) to ensure continuity in the hardness of the formwork. The first resin layer (10) has the function of stiffening the Lycra fabric (7). While the fiberglass (11) and the second resin layer (12) have the function of increasing the strength of the formwork. The number of resin layers (10 or 12) can be between two and seven, that is, there must be at least two resin layers (10 or 12), while the number of fiberglass layers (11) can be be between one and six, that is, there must be at least one layer of fiberglass (11). Figure 10b of MODE 1 shows the application of three layers of fiberglass (11) and four layers of polyester resin (10 or 12), being within the limits described above. The above serves to increase the thickness of the formwork, always starting with a layer of resin (10) on the Lycra (7) and then a layer of fiberglass (11), then another layer of resin (12) on the fiber of glass (11) and the layers alternate; resin (10 or 12), fiberglass (11), resin (10 or 12), fiberglass (11), thus completing the desired number of layers and taking care that it is always finished with a resin layer (10 or 12), to moisten the fiberglass (11), as illustrated in Figure 10b of MODE 1. Once the layers of resin (10 and 12) and fiberglass (11) have completely dried, the fencing bars (8) are assembled, which in this case is only one. Figure 16 shows the fencing bar (8) fixed on the free crossbar (So), said fencing bar (8) has the function of preventing concrete runoff and that in this case completes the formwork, as the area of junction between the wall (18) and the roof, the demolished perimeter edge of the slab (17) and the fencing bar (8) form a kind of drawer where the concrete will be emptied later.

The fencing bar (8) is fixed to the free crossbar (Sb) with the aid of known means, including; nails, wire, pins, screws and nuts, rivets, staples, etc. The fencing bar (8) must have a minimum fencing height of ten centimeters, in addition it can also be manufactured with a wooden structure (boards, planks, bars, struts, etc.) or with a steel structure (sheet, profiles, channels, etc.)

When the fencing bar (8) has been mounted and the formwork has been stiffened, the perimeter rods (13) and the load rods (21) are placed, figure 17. The perimeter rods (13) as in MODE 1, goes on the periphery of the roof and its function is to withstand the edge forces, in this case and as shown in Figure 17, only perimeter rods (13) are needed on two edges of the roof, the free edge (stringer Sb) and the edge glued to the wall (18). In this case, loading rods (21) that have the function of and ar the structure of the roof cover (18) are also used, this through the insertion of the loading rods (21) in each of the ios anchoring holes (19), figure 13 and figure 17, this to ensure a monolithic joint between the wall (18) and the roof. The perimeter rods (13), like the load rods (21), consist of a package of at least two rods of the number four minimum, the union between the perimeter rods (13), the anchor rods (2) and the loading rods (21) can be made with the aid of known joining means, among which are included; welding, annealed wire ties, bends, etc.

Whenever the perimeter rods (13) and the load rods (21) have been mounted and these have been fixed to the aging rods (2), the steel grid (14) is formed, which is formed by strips. of wire rod, double strips of annealed wire or electro-welded mesh ^, Figure 18, shows the assembly of the steel grid (14). The grid Steel (14) is constructed on site, with the help of X * wire (a quarter of an inch), with double strips of annealed wire or electro-welded mesh. Each wire strip is fixed at most ten centimeters above the length of each of the perimeter rods (13), and in this case, of the anchor rods (2), this with the help of known fixing means, which include; welding, annealed wire bends, ties, etc., obtaining a kind of electro welded mesh. The ties of the crossings of the grid (14) are made with the aid of known mooring means, among which is included; annealed wire, bends, welding, etc. The total surface area of the roof to be constructed must be covered and the anchor of the steel grid (14) must be checked in each and every one of the perimeter rods (13), as well as in the anchor rods (2) and in the load rods (21). In the case of using annealed wire for the fabrication of the steel grid (14) double strips of annealed wire should be placed for each wire rod that is replaced. In addition, electro-welded mesh can be used for the steel grid (14), but it must be supervised that the mesh acquires the shape of the cover, so that it is inside the concrete casting.

Once the steel grid (14) has been assembled and fixed, the concrete mixture is made, the concrete mixture can be prepared with known structural filler materials, including; sand, gravel, granite, conventional cement, mortar, translucent concrete, transparent resin, water, catalysts, etc. The concrete used to fill the formwork can be conventional concrete, translucent concrete or transparent resins. The concrete mixture must be manageable but always looking for something "dry" to remain, to avoid runoff. Whenever the concrete mixture is ready, it is then emptied on the surface of the formwork, it must be rounded in order to supervise that it has a minimum thickness of 6 centimeters, in addition to making sure that it covers the entire surface to the steel grid (14), as this represents the reinforcement of the roof. Subsequently, the concrete must be taped so that it is compacted.

The concrete must be allowed to set at least 15 days before removing the formwork mold (Lycra (7), resin (10 and 12) and fiberglass (11)), if desired, or you can opt for Leave it as part of the structure. However, if the formwork (Lycra (7), resin (10 and 12) and fiberglass (11)) is to be part of the roof, wax or release agent should be applied on the stringers (Sa and 5b ), finally that the formwork does not stick to the stringers (5a and 5b). Subsequently, the rigor finishes (resanado, polished and paint) are given and a finished cover (16) is provided, as illustrated in figure 19, which shows the finished cover (16).
