Description

DESCRIPTION

DRY BUILDING STRUCTURAL CONSTRUCTION SYSTEM,

REMOVABLE, TRANSPORTABLE AND REUSABLE

OBJECT OF THE INVENTION

The present invention refers to an absolutely new, demountable, easily transportable and reusable construction system of structures for dry buildings, with all its metallic constituent elements, such as footings, floors, pillars and beams, in folded galvanized sheet steel, joined together between them by screws, focused on environments with a great housing or extreme need such as contingency areas, responding to a level of demands in their realization that currently do not exist or are not well resolved by other systems.

The housing response that is currently given to settlements in the aforementioned places, temporary in many cases, is usually carried out with fabric modules (tents) and / or subsequent supply of sheet metal huts that both due to their constitution and the materials used and their treatment does not provide the basic satisfaction required for the development of daily human activity with a minimum of dignity and comfort, according to article 25 of human rights, without considering the absence of controls in the manufacturing, supply phases , assembly and implementation, and the consequent impossibility of reuse of said architectures, which are for the most part abandoned in their first destination due to their weak and inadequate construction and the deficient materials used, as well as their functional obsolescence that makes their use unfeasible. reuse. No minor issue due to the economic loss that this represents, as well as the footprint in terms of waste that such action entails.

The analysis of the construction characteristics of the existing offers on the market today in a degree of maximum demand is reduced, almost entirely, to shaped sheet and / or wood huts whose problems and characteristics are listed below:

1.- They are not an industrialized system or with a very low level of industrialization, and their conception is usually reduced to supplying sheet metal panels that are mounted on destination practically without any type of assembly control, in the best of cases the structural system is assembled and secured by means of welding, completely eliminating the possibility of a rational disassembly.

- Por la naturaleza del mismo, dichas casetas son irrecuperables para otro destino al tener un sistema de montaje arbitrario, que junto a la falta de sección de las chapas que lo constituyen, resulta imposible ser reutilizadas en otro lugar puesto que normalmente sus componentes quedan deformados en su primer montaje.2.

- Due to the nature of the same, these booths are irrecoverable for another destination as they have an arbitrary assembly system, which together with the lack of section of the sheets that constitute it, it is impossible to be reused in another place since normally its components are deformed in its first montage.

- Most of the solutions adopted today to be assembled need to make a concrete floor in order to rest on a rigid continuous support.

- Quedan frecuentemente abandonadas al no ser posible su desmontaje perdiéndose todo su valor económico y funcional.Four.

- They are frequently abandoned as their disassembly is not possible, losing all their economic and functional value.

- They leave a waste footprint impossible to recycle for the most part and a physical footprint in nature that represents not only a significant loss of resources, but also a very negative impact on the landscape.

- As a consequence of the previous point, the need to carry out works prior to their assembly with transformed materials "in situ", such as concrete, is evident, which is not an easy material to carry out in all points of the earth and less than said execution is carried out with the relevant controls.

7.- Its conception and subsequent assembly of the currently used solutions does not comply with any type of current construction regulations both at European and worldwide level.

8.- The concept of creating the components that make up the type of building currently used, does not contemplate in its construction phase the optimization of the format of the pieces for transport, based solely on

the possibility of being placed in a closed container for land transport

and / or sea and land, making air transport impossible in practice. The non-optimization of the format of the pieces in the engineering development process, preventing the necessary transport of the same, increases the final price of the product and maximizes the carbon footprint by increasing the amount of transport to be carried out.

- The constructions that are used today, which, as previously explained, paying very little attention to matters as basic as sealing, insulation or wind leaks, factors to take into account to combat natural agents in highly adverse weather zone.

- Todo ello hace que para llegar a un grado mínimo de habitabilidad sea necesario un derroche continuo de energía eléctrica en forma de producción de frigorías o calorías.10.

- All this means that in order to reach a minimum degree of habitability, a continuous waste of electrical energy is necessary in the form of production of frigories or calories.

As a consequence of the points previously exposed, it is considered appropriate to create a new construction system that responds to all the deficiencies found in current systems, with which a response can be given quickly, easily and constructive guarantees to the fact of housing and services in areas. with a situation of deep need for buildings for multiple uses, contingency or natural disasters.

Likewise, the need to create a system that does not need complementary construction facts at destination is delimited, such as concrete works or materials that need water in their constitution. For this reason, the requirement to create a dry construction system is considered, without the contribution of water or the transformation that needs it.

Its development has involved a very intense level of effort, activity and creativity, and it has been necessary, for this purpose, to create an interdisciplinary team made up of Architects, Civil Engineers and Metalworkers, experts in development work, construction and installation of buildings for the aforementioned uses, in order to first define the needs to be demanded of the system, choose its base material, and lastly develop and calculate the same synthesized in the calculation and manufacturing annexes of all parts of the system attached to this report. Being demonstrated the inventiveness and creativity achieved to give a final shape to a system totally new modular and different from any other existing system, which also complies with the proposed requirements and the CTE (technical building code).

The advantages of the present invention are therefore based on the following principles:

- Achieve a building that can be installed in any natural environment on earth, without producing an environmental impact in its implementation, that can be dismantled without causing deterioration in the elements that compose it, and that does not leave a mark on the natural environment in the later phase of disassembly.

- That it be a "removable and easily transportable" system in order to be "reused" in other destinations at the end of its tasks.

- That it is a very versatile system that allows different solutions to be given to housing and other multiple uses, as well as to allow its transformation and / or extension to the construction event initially carried out, while maintaining its functional requirement of habitability.

- That its constructive reality is "easily transportable in standard containers" in order to be able to carry it out indiscriminately by air, sea and land, and as a consequence, be able to access it for installation anywhere on earth.

- That its "modular, easy and quick implementation" assembly concept makes it an optimal system for the intended objective, which is none other than responding to a humanly worthy and consistent construction event, including construction requirements in contingency areas, complying with the same, with all the regulations on technical matters in the Spanish-CTE approved environment, and therefore European.

- That its assembly, due to its ease and simplicity, does not require high technological training and therefore is easily executable by workers who, without a specific qualification and with a minimum training course of a short time, can carry out the assembly of said constructions - That its conception, manufacture and assembly be a "dry architecture", without the need for the contribution of complementary or transformable materials for its constitution, such as water, at the destination. concretes ... etc., which, understandably, are not elements that can be found easily in many areas of the earth and even less if they are in contingency conditions or natural disasters. This aspect turns out to be substantial when evaluating the inventiveness of the system, since until now a total construction system had not been proposed that would cover the construction fact with a "single material" such as sheet steel, for the formation of footings, load-bearing structure, slabs and load-bearing façade elements.

- That the level of habitability and final health required in said construction is comparable to minimum standards of habitability for human use.

- That it responds to a "non-existent supply worldwide" of this type of construction. It is important to point out that at present there is no solvent, technical or logistics offer of modular building that is easy and quick to assemble and that complies with the international market. in turn, with the regulatory technical requirements.The system to be patented aims to make up for this absence by providing a technical, quick and habitable response according to Western standards, with an efficient staging that can be carried out anywhere on earth.

- That its industrial construction standards comply both in its construction calculation and in its final assembly with the regulations at European level and therefore extrapolated to any global technical requirement.

The industrial application of this invention is within the constructive experience in settlements executed in different points of the earth, with architectures in contingency situations or / and natural disasters. The system to be patented is developed with a sense of universality of the construction system.

BACKGROUND OF THE INVENTION

Although no invention identical to that described has been found, we present below the documents found that reflect the state of the art related thereto.

Thus, document ES2452726A1 proposes a modular, prefabricated and removable building system that is carried out in situ by assembling semi-spherical wedge and quarter-cylinder type modules, generating a roof with curved shapes based on half sphere and half cylinder, each module results from the in situ union of prefabricated panels, panels that are curved if they are used for the enclosure and flat if they are intended for the slab, each panel being a piece with structural qualities and thermal and acoustic insulation, and also incorporating pipes and plumbing pipes, and said building being totally or partially removable. The modular building system proposed by the aforementioned patent refers to modules and panels other than the structural elements described by the main invention, in addition to limiting the configuration of the constructed building, while the system of the main invention allows infinite possibilities. and different structural configurations.

ES2450642A1 describes an industrialized building construction system, characterized in that it comprises - a building foundation; -some pillars for the transmission of loads from the building to the foundations; - factory-made enclosures, of the same thickness as the pillars, comprising multilayer panels and means for joining said enclosures to the pillars; - an interior partition made at the factory, comprising multilayer panels and means for fixing the same to the floor, sides and ceiling, e; -installations mounted between the multilayer panels in the factory and carpentry elements. The main invention, however, is based entirely on sheet metal panels folded and joined by screws, not on multilayer panels as described in the aforementioned document, so that the novelty and inventive step are not compromised.

ES2176247T3 proposes a building structure of the type formed by prefabricated frames including wall frames that extend between floor frames or between a floor frame and a roof frame, the wall frames being formed by a plurality of transportable panel frames the like each of which has upright frame side members, adjacent upright frame side members of adjacent wall panel frames separated from each other and joined by joint members disposed between said adjacent frame side members, the joined frame side members providing load paths for directly transferring roof, wall and floor loads to floor support means, and that said bonding members are shaped members. plate crossed by tapped openings; Each tapped opening has a length that allows opposing connecting bolts inserted from each end of the opening to be operatively fixed therein and each of said side frame members is bolted by at least one through bolt that is threaded into one end of said tapped opening. Again, structural elements other than those proposed by the main invention are used, such as steel sheet panels.

ES2011532A6 claims a system for the prefabrication and assembly of fixed and transportable buildings, being useful for the construction of any type of house, such as apartments, bungalows, hotels, chalets or warehouses of all kinds, that the prefabricated pieces will be of such dimensions that with a single piece the foundation, the base, the wall and the finish are defined, so that the prefabricated pieces can be solid, with holes, sandwich type, or alveolar, and in their manufacturing process, they will incorporate all the necessary elements , both design and technical, being able to carry out the manufacture of the pieces by sliding molding machines or with molds, having foreseen that the setting material can be vibrated or not, so that in the case of being vibrated, it can be carried out by means of portable vibrators or vibrating tables, with the particularity that in the case of vibrating through vibrating tables, you can use as many vibrating tables as you want pieces be done by cycle, incorporating all the elements to the vibrating tables, as they are static, or by using assembly lines in which it is the part that moves through a closed or open circuit, incorporating along him, all the elements of the piece. In this last cited document, different and more complex structural elements and pieces are used again than the folded and joined sheets with which the entire structure for dry, removable, transportable and reusable buildings is made, object of the main invention.

Conclusions: As can be seen from the research carried out, none of the documents found solves the problems posed as the proposed invention does.

DESCRIPTION OF THE INVENTION

The structural construction system of dry, removable, transportable and reusable buildings object of the present invention is constituted from a modular system adjustable to different spans spans, composed of footings, pillars, beams and slabs, all of them executed in sheets formatted in laser process and shaped in a folder, galvanized screwed together with stainless steel screws, perfect for generating with its geometry the different inertias necessary to make the desired building.

The spans and building heights can vary by reducing or increasing the dimensions and sections of the elements that make up the system. In addition, all the constructive elements that make up the building of the architectural space do so in the total absence of water, which is why we can speak of "dry architecture" as there is "no necessary transformation or manipulation" to carry out the constitution of said elements in destiny.

The technology necessary for its realization, given that it is very simple, allows it to be produced and manufactured in any country with sufficient technology, and its assembly can be carried out by assemblers with very low qualifications, with few tools and practically no machinery, without the need for it. of aids of auxiliary means of elevation.

For the transport from the country of transformation and production of the components, it has been foreseen in the design of the pieces their easy coupling between them in order to optimize it economically and reduce the carbon footprint as much as possible.

Likewise, it has been foreseen that each piece, be it a pillar or beam or each constituent unit of the slab, weighs less than 60 kg in order to be able to be handled by two people without the help of auxiliary means.

Being an industrial procedure, which avoids the traditional construction of conventional construction, its conception requires a sequenced and controllable procedure, which makes the final result a verifiable and homologous fact through a quality control of all its phases.

The object to be patented is the design of each of the constituent elements of a removable system:

- Metallic shoe

- Pillar made up of 4 folded and screwed pieces

- Beam made up of 2 folded and screwed pieces

- Folded sheet metal slab module

The calculation and manufacturing procedure of the elements that make up the system has been adjusted to the Technical Building Code-CTE, in force in the Spanish State and approved at the level of European guidelines on construction.

DESCRIPTION OF A PREFERRED EMBODIMENT

A preferred embodiment of the structural construction system for dry, removable, transportable and reusable buildings that is the object of the present invention, with reference to the numerical references, can be based on a modular system adjustable to different spans spans, composed of pillars (3, 7) , beams (5), connection nodes (4) between them, slabs (6) and footings (1, 2), all of them executed in sheets galvanized folded plates screwed together with stainless steel hardware, and their corresponding and specific support base and structure shoes, which will be described below, to generate with their geometry the different inertias necessary to make the desired building.

Support base (1)

It is the support element of the building structure on the surface of the land, being an isolated surface-type foundation, and it is achieved by building a framework of metal plates assembled together, by means of welding and / or screwed folded sheets. This is therefore a dry foundation that supports all kinds of loads exerted on the building as a whole, allowing direct support of the same without causing excessive settlements that may affect the correct functionality of the structure and the elements supported by it (Figure 1) .

The buildings, object of the present invention, which are going to be provided with this type of dry foundation, admit a growth in their length and depth, as well as in their height, and depending on a wide sequence of factors, among Others, admissible loads of the land, wind loads, dynamics, seismic, etc., to be taken into account for the adequate support and stability of the building, mean that the type of foundation developed has different different realizations:

For smaller buildings, in areas with minimal exposure to climatic factors, it will be possible to directly superimpose the support base (1) on the previously compacted existing ground (Figure 2).

For smaller buildings and in areas with greater exposure to climatic factors, it will be possible to directly superimpose the support base (1) on the previously compacted existing ground and to ensure the absence of landslides, the base will be anchored to the ground by means of specific anchoring elements depending on the wind loads considered in each specific case (Figure 3).

In soils with a lower bearing capacity, areas of greater exposure to wind loads or buildings of more than one height, an excavation of dimension in plan slightly higher than the measurement of the support base (1) and depth defined by the specific calculations carried out. In this excavation the support base (1) will be introduced on which and continuing with the assembly operation the following components of the structure will be assembled. Once the pieces of the structure have been assembled up to the height of the ground floor slab (6) and the correct dimensions of the same have been verified, the cove made for the introduction of the metal footing will be filled, with the same earth extracted from the excavation itself (Figure 4).

The number of metallic footings that each building will carry will correspond to the result of dividing the dimensions of the building by a modulation of 4x4 meters. Example: a 4x4 meter building will have 4 supports, a 4x8 meter building will have 6 supports, an 8x8 meter building will have 9 supports, etc.

Structure base (2)

It is the first component of the supporting structure (figure 5), and a transition element between the support base (1) and the starting pillar (3). By forming a set with the support base (1) and using the threaded bolts arranged in this support base (1), the base of the structure (2) serves at the same time as positioning, leveling and correcting for the perfect plumbing of the pillars (3, 7) of the structure.

This will be achieved by manipulating the nuts arranged on the threaded bolts of the support base (1), positioning a set of nuts below the base plate of the structure (2) and another above this same plate, in such a way that the lower nut is raised or lowered according to the level indicated to us to level in height, acting in the same way once the height is positioned, to achieve a perfect plumb, once the leveling and plumbing have been achieved, the tightening of the upper nuts to block any type of movement (Figure 6).

Once the leveling and plumbing work has been completed, with the plate properly held by the upper nuts, a band is made on the total perimeter of the circular plate and then a special resin is injected through the holes provided for this purpose in the plate. So that the separation between plates It is perfectly filled and once the chemical reaction has taken place and the total hardening of the resin, both bases (1, 2) become a single piece. (Figure 7), without prejudice to the concept of easy disassembly since once the upper plate of nuts is released, both plates detach with a simple blow and the resin will detach from the lower plate, for this we will have previously impregnated the plates with a release agent.

Starter Pillar (3)

Together with the two pieces previously described, and by means of stainless steel screws with anti-seizure treatment, it forms an inseparable set of pieces, since they complement each other (Figure 8).

There are three models of starter pillars (3), model A (3 '), which is used for corner pillars, model B pillars (3' '), which are used for intermediate facade pillars and type C pillars (3 '' '), which are used for the interior pillars (Figure 9).

These pillars (3) are made up of four pieces of folded W-shaped sheet metal that are assembled together to form a pillar with a tubular shape.

The starting pillar (3), in addition to its mission of being a pillar, is also a leveling element. In Figure 10 it can be seen that, on the folded sheet itself, in the lower part of the pillar, there are some perfectly defined marks (8) (such as a start of cut), where each mark (8) is spaced 120 mm apart. being 5 the number of existing marks, there is a total of (120x5) 600 mm; These references are to be able to make a cut through the indicated reference, reducing the length of the pillar by 120 mm, being able to reduce this pillar (3) to a total of 600 mm, which allows a building of 12 meters in length to be installed on a slope of 5% without any type of bench (Figure 11). The cuts must always be made by the indicated references so that the holes in the pillar (3) coincide with the holes in the base of the structure (2) and that the lower part of the pillar (3) rests on the waiting platform that It is at the base of the structure (2).

Coarse leveling is achieved by adjusting the length of the starter pillars (3), fine leveling is achieved by operating on the nuts of the metal shoes. In addition, the lower part of the pillar must always rest on the platform of the base of the structure (2).

Connection node between beams and columns (4)

Starting from the starting pillar (3) at the ground floor level, it is necessary to equip the structure with horizontal beams (5) to support the future floors. For this, it is necessary to add to the pillars (3) some type of device that allows the connection of the beams to them, in addition to continuing to grow in height, for which this element, connection node (4), must also be planned to connect the next pillar (7).

para encuentros en esquinas (L) pilares, nudo tipo 2

para encuentros en tres puntos (T) pilares, nudo tipo 3 (4’’’) para encuentro en 4 puntos (X) pilares (Figura 13).There are three types of knot (4), type 1 knot

for corner junctions (L) pillars, type 2 node

for meetings in three points (T) pillars, node type 3 (4 ''') for meeting in 4 points (X) pillars (Figure 13).

These nodes (4) are installed on the upper tip of the starter posts (3), properly positioned and screwed (figure 14). Each column position (3) will have the appropriate type of node (4) (Figure 15).

Beams (5)

The beams (5) are made up of six pieces in addition to the hardware:

Piece 1 - Simple Omega (5 ') (Figure 16)

Piece 2 - Omega with forged cover (5 ’’) (Figure 17)

Part 3 - Simple anti-torsion angle (Figure 18)

Part 4 - Threaded anti-torsion angle (Figure 19)

Part 5 - Threaded Washer (Figure 20)

Part 6 - Through washer (Figure 21)

Part 7 - Joint cover plate (Figure 22)

And in some cases, the beam (5) is complemented with an eighth piece: Piece 8 - Z facade panel support (Figure 23)

A standard beam (5) is made up of 1 simple omega (5 '), 1 omega with forged cover (5' '), 8 through washers, 4 threaded washers, 2 simple angles, 2 threaded angles and 6 joint cover plates, assembled according to sketch (Figure 24).

The pieces are assembled as they are assembled in the place where they have to be installed, minimizing transport.

The mounting system would be:

Carrying all the parts and screws to the place of installation, mounting with the simple omega screws on the protruding ears of the nodes (4), this being the one that will remain on the outside of the building. This omega will be on one side separated from the knot (4) with a through washer and on the inside face it will be fastened to the knot with a threaded washer. Next, the two simple anti-torsion angles and the two threaded ones will be installed and then all the cover plates together, to finish mounting the omega with the forged cover inside the building, leaving the longest wing at the top.

During the assembly it is not advisable to fully tighten the hardware, just leave it warm, and once all the beams (5) corresponding to a plant have been assembled, all dimensions will be checked, including diagonals, levels and leads, for, once checked and ensured that everything is in perfect condition, proceed to tightening the screws with a torch machine giving the last pressure with a torque wrench.

Once all the beams (5) of the first floor have been assembled, there will be a framework ready to receive the slab (6) (Figure 25).

Forged (6)

It is a formed sheet metal part that has two versions: the standard part (6 ') (figure 26) and the abutment against pillars (6'') (figure 27). This piece is simply installed resting on the beams, embedded between the wings and tightly held together, which in order to avoid cracks have a joint along its entire length Intumescent that also serves as a sealing element for smoke and fire in case of fire.

To avoid movements of the profiles that make up the slab (6), these are anchored by means of T-shaped pieces screwed to the beams (figure 28).

The slab (6) functions as a floor and a ceiling at the same time. In the case of use as a floor, this slab is covered with different materials (stamped aluminum sheet, vinyl floor, laminated flooring, etc.), depending on the use of the building. In the case of using the slab piece as a ceiling, it can be seen as is or it can be covered with some type of false ceiling. Likewise, the profile can be filled on the inside with insulating material to give it greater thermal and acoustic insulating power. The installation of the pieces that make up the slab is always in the form of a checkerboard, with this an overload of 500 kilos per square meter is achieved and guaranteed, since each of the beams only receives the load of a single slab (Figure 29) .

The slab (6) of the ground floor also serves as a platform from which to assemble the upper structures, where it will only be necessary to use a light aluminum scaffold that raises the staff to approximately one and a half meters above the height of the the platform.

Pillars (7)

For the description of the main pillars (7), the definition of the construction system of the pillars previously called "Start pillars (3)" can be applied, with the difference in height with respect to the previous ones, all the pillars (7) of the same plant they are of the same length; There are three models of pillars (7), model A (7 '), which is used for corner pillars, model B pillars (7''), which are used for intermediate facade pillars and type C pillars (7 '''), which are used for the interior pillars. The type pillar (7) (Figure 30) is the pillar of adequate height for buildings applied to housing functions or for those destined to offices and similar services. These pillars (7) allow the installation of a second floor on them, therefore a two-story high building can be built in addition to the roof floor, without the need to modify or expand the dimensions of any of the parts that make up the system. The pillars (7) are susceptible to growth in height for the manufacture of other buildings destined for different applications such as kitchens, dining rooms, classrooms, warehouses, medium-height hangars and a wide etc. Of applications.

The pillar (7) is made up of folded W-shaped sheet metal profiles, and there are three pillar configurations, each one configured for its position in the entire structure (Figure 31):

The structure of the building comprises wings that are part of the pillar, intended to collect the facade cladding. This enclosure is achieved by installing a sandwich panel (two pre-sealed sheets and intermediate insulation) that in the basic version will be seen from the outer face and the inner face.

For the different types of use of the building, this panel may be covered with other materials and finishes, both on the outside and inside.

The pieces that, forming part of the structure, have to be specifically installed to facilitate the subsequent configuration of the facades are the so-called support omega (Figure 34), and are installed in a vertical position connecting the lower beam with the upper beam, whose The main function of this element is to serve as a support for the façade panel, providing this panel with the necessary resistance to comply with standards of resistance to wind pressure.

These omegas can be installed on the beams (5) every approximately 60 centimeters, so that they not only serve exclusively to reinforce the effort of the panels, but they will also serve to make the partitions of the panels to insert the access doors and windows, these same pieces being the ones that will support the carpentry and glazing.
