Description

[0001] RECONFIGURABLE STRUCTURAL CONSTRUCTION SYSTEM, WITH STANDARDIZED PREFABRICATED ELEMENTS FOR MULTI-PURPOSE BUILDINGS

[0002] FIELD OF INVENTION

[0003] The present invention falls within the fields of architecture, civil engineering, and construction; in particular, it relates to structural systems for generating single- or multi-story building structures for assembly on open land, on land with other uses such as parking lots, or on top of other buildings, and which can be disassembled for storage or reassembled elsewhere. More specifically, it refers to a reconfigurable structural construction system with standardized prefabricated elements for buildings with various purposes.

[0004] BACKGROUND OF THE INVENTION

[0005] Structural steel construction systems are generally designed and configured to be permanently installed on the construction site, using welding to join the different pieces, association of welded pieces with fixed bolts, footings or blocks configured to embed the lower end of steel columns that remain permanently anchored, and which cannot be recovered for use in another construction or moved from the site where the work was built if required; although they have advantages in terms of strength and durability, they also present significant challenges in terms of investment, planning, regulations, maintenance and environmental considerations.

[0006] These permanent steel structural construction systems present certain specific problems and considerations, such as: a) the investment is significant, and if the project is canceled for any reason or changes, that investment cannot be recovered, which implies a significant financial risk; furthermore, if site conditions or the needs of the construction area change over time, the structure may become inadequate or unnecessary, or it may no longer be reconfigured; b) permanent steel structures have a limited residual value in the market; c) due to their permanent nature, very precise planning and design are required because errors or modifications to the project that necessitate structural changes can be costly to correct or can lead to serious structural problems; d) the construction of permanent structures can generate waste of resources, since they cannot be reused for other projects.Steel structural buildings are also known that are made with bolt or screw connections that allow the interconnection between the elements of the metal structures, allowing for faster installation. These elements are prefabricated in the workshop to minimize on-site work and have better control of the assembly process; however, they always require welded pieces, welded plates, bolts, welded connectors, etc., to be welded on-site.

[0007] Furthermore, permanent steel structural systems, comprised of beams and columns in their permanent position, are not designed for diverse applications. They are typically designed with a single load-bearing capacity based on their intended use, such as residential, commercial, or other specific applications, and are configured and designed for a structural strength according to the project. This can require columns, beams, and other elements of varying dimensions, schedules, and structural strengths, thus presenting a multitude of disadvantages that have already been discussed.

[0008] The main function of the present invention is to provide a reconfigurable structural construction system with standardized prefabricated elements for multipurpose buildings, with standard dimensions and reconfigurable to the specific needs of the site where it will be installed. The benefit of this invention is that it offers a prefabricated structure that can be configured in any direction along a Cartesian axis and is applicable to various functions, such as an entertainment building, housing, offices, or other uses.

[0009] A search was conducted to determine the closest prior art, and the following documents were found:

[0010] Document CN105735322A by Wang Fuming et al., dated February 4, 2016, was found, disclosing a construction system for a rigid-flexible, composite, recoverable, and anti-seepage support structure for excavating foundation pits, slopes, and municipal pipelines, as well as the method. The invention relates to a method for designing and constructing a rigid-flexible, composite, recoverable, and anti-seepage support structure system.The method comprises the following steps: (I) Steel profile slope protection piles are constructed; (II) H-shaped steel top beams and H-shaped steel breast beams are installed; (III) Steel panels are installed; (IV) Sequential vertical excavation is carried out in layers and sections, steps (II) and (III) are repeated, construction is carried out to the design depth and the construction of the rigid-flexible composite anti-seepage recoverable support structure system is completed; (V) Once the function of use of a support structure has been fulfilled, with the start of the backfilling work of the pit, recovery work can be carried out.The rigid-flexible composite anti-seepage recoverable support structure system built through the method truly reflects the characteristics of a temporary safety measure adopted by the foundation construction of foundation pit engineering and has the advantages of safety, reliability, speed of construction, advanced technology and the ability to be recycled, excellent economic indices and the like.

[0011] While the document reveals a construction system for recoverable steel structures, it comprises non-standardized elements specifically configured to build a recoverable, anti-seepage support structure for excavating foundation pits, slopes, and municipal pipelines. These structures are used to prevent landslides, and once the foundation, slope, or pipeline is in place, the system can be removed. However, it is not suitable for constructing structures for multipurpose buildings.

[0012] Document RO135122A0 by Stánilá Alexandru and Baraga Constantin-Perino, dated February 9, 2021, was found, revealing an integrally prefabricated, transportable, single-unit, parallelepiped building module, expandable on-site into functional volumes, and processes for its manufacture. The building module comprises a spatial metal structure (1), with dimensions equivalent to those of a standardized shipping container, composed of a rectangular lower frame (2), consisting of two lower perimeter beams (3) and one or more lower floor beams (4), two lower end beams (5) and several floor beams (6), beams (2) that are joined to the beams (5) by means of standardized corner brackets (7) provided with several openings (8) through which the construction is fixed to the site or to the platform of the means of transport.with standardized conventional devices. The process comprises a first execution stage in which a structure (1) is made, the second stage in which one / two sets of folding walls are made, after which in the third stage the roof sets are made, in the fourth stage the floor panels, in the fifth stage a detachable system is made to lift the floor panels, in the sixth stage sealing elements are manufactured for transport, in the seventh stage the parallelepiped construction is prepared for transport, in the eighth stage a horizontal construction is made and the plan is prepared on site for the assembly of the construction, in the ninth stage the parallelepiped construction is loaded, in the tenth stage the expansion procedure begins, on each side of the module, in the eleventh stage, on the sides with folding roofs, they are folded, in the twelfth stage the longitudinal walls are folded at a right angle,In the thirteenth stage the adjustable arms are lowered, in the fourteenth stage the partitions are assembled, in the fifteenth stage the modules can be stacked on top of each other, and in the final stage rows of houses or apartment blocks can be built.

[0013] As can be seen, the fully prefabricated parallelepiped building module is a prefabricated structure that can be transported to the construction site and where it can later be adapted and expanded to create rows of houses.

[0014] The invention described in document RO135122A0 cannot be considered a reconfigurable structural construction system comprising standardized prefabricated elements that allows for the creation of buildings for various purposes, with standard dimensions and reconfigurable to the needs of the site where it is to be installed. It is designed to be prefabricated in a plant and transported to the site and cannot generate configurations other than that of a fully prefabricated parallelepiped.

[0015] Given the need for a reconfigurable structural construction system, with standardized prefabricated elements for buildings with various purposes, with standard measurements and reconfigurable to the needs of the land where it is to be installed, which can be configured in all directions of a Cartesian axis and applies to various functions such as an entertainment building as well as housing, offices or other uses in the building, the present invention was developed

[0018] Another objective of the invention is to provide said reconfigurable structural construction system, with standardized prefabricated elements for buildings with various purposes, which also allows the generation of temporary buildings, which can be demountable, recoverable and if necessary used for another building in other sites, that is, that it is relocatable.

[0065] DETAILED DESCRIPTION OF THE INVENTION

[0066] The characteristic details of the reconfigurable structural construction system, with standardized prefabricated elements for buildings with various purposes, are clearly shown in the following description and in the attached illustrative drawings, with the same reference signs serving to indicate the same parts.

[0067] Referring to figures 1, 1 a and 1 b, the reconfigurable structural construction system, with standardized prefabricated elements for buildings with various purposes, comprises standardized IPR profiles in dimensions (1) whose web (2), the flanges (3, 4) comprise a pattern of perforations (5) equidistant and distributed in two parallel lines along the entire longitudinal section of said web (2) as in both wings of the two upper (3) and lower (4) flanges.

[0068] Referring to figure 2, four standardized IPR profiles in dimensions (1) with anchoring elements (6) to anchor to the floor are shown, where said standardized IPR profiles in dimensions (1) act as columns (1 a).

[0069] Referring to figures 3, 4 and 5, a standardized IPR profile in dimensions (1) is shown acting as a column (1a), showing the fixing of L-shaped support brackets (7) that define a vertical arm (7a) joined perpendicularly at its upper end to a longer horizontal arm (7b) and a central reinforcing bracket (7c) fixed in the inner angular zone; said vertical (7a) and horizontal (7b) arms having perforations (7d) to receive fastening means (7d); where said vertical arm (7a) is configured to be fixed with fastening means (7e) either on at least one external face of the flanges (3, 4) or on a face of the web (2) of each IPR profile acting as a column (1a), at different heights as required; the longer horizontal arm (7b) being arranged as a means of support and fixing the corresponding end of each IPR acting as a beam (not shown in these figures).

[0070] Figure 6 shows a standardized IPR profile in dimensions (1) that serves as a beam (1 b) at whose connection end L-shaped connecting angles (9) are fixed with fixing means (8) defined by a shorter vertical arm (9a) fixed perpendicularly at its upper end to a longer horizontal arm (9b) and a central reinforcing bracket (9c) fixed in the inner angular zone; where said longer horizontal arm (9b) comprises holes (9d) configured to receive the fixing means (8) to connect in pairs on both faces of the web (2) defining a quadrangular fixing element (10) of the ends of each IPR profile that serves as a beam (1 b).

[0071] Referring to figures 7 and 7a, specifically in figure 7 an interconnecting bracket (11) is shown defined by two parallel vertical plates (12, 13) joined with central plates in vertical and horizontal positions (14, 15) in the form of a cross, configured with holes (16) in said parallel vertical plates (12, 13) to receive fastening means (17) to be fixed through one of said parallel vertical plates (12 or 13, depending on how it has been joined) to the corresponding quadrangular fastening element (10) defined by the pair of L-shaped connecting angles (9, see figure 6) that are joined with the fastening means (8) to the end of an IPR profile that acts as a beam (1 b, see figure 6) and the other parallel vertical plate (12 or 13) configured to be fixed with fastening means (18) to one of the faces of the web (2) of said IPR profiles that act as a column (1 to).The end of the IPR profile acting as a beam (1b, see Figure 6), which connects to the interconnecting bracket (11), rests on an L-shaped support (7), specifically on the longer horizontal arm (7b) previously fixed to the web (2) of each IPR profile acting as a column (1a), and is secured with fastening means (not shown). This method of fastening and the use of the interconnecting bracket (11) are necessary when the connection of an IPR profile acting as a beam (1b) must be made to the web (2) of IPR profiles acting as columns (1a) to form a perimeter ring between columns, as shown in Figure 10.

[0072] Figure 7 also shows the end of a second IPR profile that serves as a beam (1 b) which, as shown in Figure 6, comprises at its connection end two L-shaped connecting angles (9) fixed with fixing means on both faces of the web (2) defining a quadrangular fixing element (10) of the ends of each IPR profile that serves as a beam (1 b). In this case, given that a perimeter belt of IPR profiles acting as beams (1 b) will be formed at a height and thus several perimeter belts at the height of the structure, said quadrangular fixing element (10) is fixed with fixing means (19) on the corresponding flange (3) of the IPR profile acting as a column (1 a) and the end of said IPR profile acting as a beam (1 b) rests on the longer horizontal arm (7b) of an L-shaped support (7) previously fixed on the flange (4) of the IPR profile acting as a column (1 a) and is fixed with fixing means (not shown).

[0073] Figure 8 shows in conventional perspective an arrangement of four IPR profiles that serve as columns (1 a) joined with the fixing means as shown and described in Figures 7 and 7a, with perimeter IPR profiles that serve as beams (1 b) confirming a first structure with a first structural perimeter belt, in accordance with the preferred embodiment of the invention.

[0074] Figure 9 shows a conventional perspective view of the joint section of the ends of two IPR profiles acting as a beam (1 b) in an IPR profile acting as a column (1 a), showing the incorporation of reinforcing angle brackets (20) that are fixed with fixing means (21) diagonally at right angles in the interconnections between the IPRs acting as columns (1 a) and the IPRs acting as beams (1 b).

[0075] According to Figure 9a, these reinforcing gussets (20) consist of an IPR profile section (22) with 45° diagonal cuts at its ends (23) and L-shaped connecting angles (9) with holes (24) to receive fastening means (21, see Figure 9) to connect in pairs on both faces of the web at the ends of each IPR profile section (22), which defines a fastening element to be fixed at one end to a zone of the IPR profile that acts as a column (1a, see Figure 9) and at the opposite end to a zone of an IPR profile that acts as a beam (1b, see Figure 9). In this way, greater structural resistance is provided.

[0076] Figure 10 shows a conventional perspective view of an arrangement of four IPR profiles acting as columns (1a) joined with the fastening means as shown and described in Figures 7 and 7a, with perimeter IPR profiles acting as beams (1b), and with reinforcing angle brackets (20) on each IPR profile acting as a column (1a) to provide greater structural strength.

[0077] Figure 11 shows a conventional perspective view of an arrangement of four IPR profiles acting as columns (1a) joined with the fixing means as shown in Figures 7 and 7a, with perimeter IPR profiles acting as beams (1b) on two levels, and with the reinforcing angle brackets (20) between each IPR profile acting as a column (1a) with the ends of the respective IPR profiles acting as perimeter beams (1b), also showing tension cables (25) fixed at their ends in connecting eyebolts (26, see Figure 11b) or in connecting angles (27, see Figure 11a) fixed in the corresponding flanges of the IPR profile flanges acting as beams (1b) or as attached two-level perimeter columns (1a) and comprising tension adjustment elements (28, see Figures 11a and 11b).

[0078] According to Figure 12, a conventional perspective view of a module generated by IPR profiles acting as columns (1a) and IPR profiles acting as perimeter beams (1b) on two levels is shown, illustrating the connection of intermediate IPR profiles (29) connected in the form of a cross that are mechanically fixed with fixing means to the IPR profiles acting as perimeter beams (1b) of the first level, as illustrated and described in Figures 7 and 7a (the same reference signs are used to indicate the same elements); but this is the case for each level; forming a cross that defines various quadrants.

[0079] Figure 13 shows the arrangement of Figure 12 where additional purlin connector angles (30) are added, with perforations that are fixed with fixing means (31) on the inner flange of the upper flange (3) of the IPR profiles that act as perimeter beams (1 b), configured to fix purlins (shown in 15).

[0080] Figures 14 and 14a show the arrangement shown in Figures 13, where a plurality of IPR profiles are added as secondary beams (32), comprising a plate (33) with perforations fixed at each end and a plurality of L-shaped fasteners (34) fixed perpendicularly and equidistant from each other on the upper flange, with a vertical arm of each L-shaped fastener (34) arranged perpendicularly with a hole; where each plate (33) with perforations at each end is configured to receive fastening means (35) to fix an interconnecting copy (11) configured in turn to be fixed to the web of IPR profiles that act as a perimeter beam (1 b) and to the web of said intermediate IPR profiles (29) connected in a cross shape, said IPR profiles being distributed as secondary beams (32) equidistant from each other in the various quadrants defined by the intermediate IPR profiles (29).Figure 15 shows the arrangement shown in Figure 14 (the same numerical references are used to indicate the same elements described above) where additional purlins (36) are added with equidistantly spaced holes configured to receive fastening means to be fixed with the corresponding "L" fasteners (34) fixed perpendicularly equidistant from each other on the upper flange of each IPR profile as secondary beams (32), on which said purlins (36) are arranged; the latter also comprise, each, a fixed plate (37) at each end with a central threaded hole configured to receive a fastening means (38) with which it is fixed at each end in the corresponding purlin connector angles (30) fixed in the inner flange of the upper flange (3) of the IPR profiles that act as perimeter beams (1 b) or of the intermediate IPR profiles (29).These purlins (36) are distributed across the various quadrants, configured to receive and secure floor, intermediate floor, or roof covering panels, as well as the upper flanges of the intermediate IPR profiles (29). Figure 16 shows the arrangement as displayed in Figure 15, forming a first floor with IPR profiles acting as perimeter beams (1b) at various levels. The same references are used to indicate some elements already described and illustrated in the preceding figures.

[0081] Figure 17 shows a conventional perspective view of a plurality of interconnected modular units forming a building in accordance with the reconfigurable structural construction system, with standardized prefabricated elements for multipurpose buildings, according to the present invention. Some numerical references are used to indicate some elements already described and illustrated in the preceding figures.

[0082] Figure 18 shows a conventional perspective of a hinge-type connector (39) each defined by a first vertical plate (40) with perforations (40a), which centrally comprises fixedly at least a pair of vertically spaced cylinders (41) and a second vertical plate (42) with perforations (42a) which on a lateral edge comprises fixedly at least a central cylinder (43), said cylinders of both vertical plates (40, 42) being configured to align and define a continuous channel configured to receive a pivot shaft (44) with a head (45) at its upper end and a locking element (46) at its lower end.

[0083] Figure 18a shows a structure incorporating the principles of the present invention, in which hinge-type connectors (39) are added to create square or angled areas as required by the project. These hinge-type connectors (39) are configured to be fastened via their first vertical plate to an interconnecting bracket (11), which in turn is fastened to the web of an IPR profile acting as a column (1a). They are also fastened via their first vertical plate (42) to L-shaped connecting angles (9) fixed to the ends of each IPR profile acting as a beam (1b). This allows for angular connections between IPR profiles of columns (1a) and beams (1b) to create square or angled areas as required by the project. Numerical references are used to indicate some elements already described and illustrated in the preceding figures.
