DETAILED DESCRIPTION OF THE DRAWINGS

[0050] In said drawings, the operational mode and the advantages of the method of construction of buildings 101 having a reticular structure 100, in accordance with the present invention, may be clearly seen.

[0051] The method is applicable to buildings of the type comprising the emplacement in situ of prefabricated slabs, which are strongly attached to the vertical columns (1-4) of the reticular structure by means of bolting, welding, riveting or equivalent procedure.

[0052] The invention is based on the following stages: [0053] Erecting a set of columns (1, 2, 3, 4) forming the vertical load-bearing structure on foundations or piles (not portrayed in the drawings); [0054] Arranging, at the lower part of the structure 100, a pile 5 of storey modules 6, fully prefabricated and factory-made, within the space defined by the columns 1, 2, 3, 4 and in the same vertical order as the definitive order foreseen for each of the storey modules 6 of the structure 100 forming the building; [0055] Hoisting simultaneously the set of storey modules 6, by means of hoisting systems of varying types, for instance cranes or winch engines, until they are positioned in their definitive emplacements at their corresponding heights; and [0056] Attaching the storey modules 6 to the columns 1, 2, 3, 4, resting on the same by means of brackets 8 by means of an appropriate technique: bolting, welding, riveting or equivalent procedure.

[0057] The columns (1-4) may be particularly metal profiles of any type, such as HEB, IPE or IPN profiles, although the inventors have foreseen that the vertical structure may be partially or totally made from other construction materials, for example concrete. In accordance with an essential characteristic of the method of the invention, each storey module 6 should be prefabricated in its entirety, featuring at source the slab 7 corresponding to one of the floors, and one or several of the following strengthening construction or installation elements: [0058] The deck 20 of an upper storey, possibly including a floor slab and paving; [0059] The main girder or beam 10 of the storey slab 7; [0060] The joists or secondary beams 15 of the storey slab 7; [0061] The ceiling 30 of the floor below the storey 6, possibly including an enclosing surface; [0062] Vertical division elements, such as interior walls and the faades of the building 101; [0063] Horizontal protrusions in projection from the structure, such as balconies; and

[0064] In the preferred embodiment of the invention, which greatly facilitates the transport and installation of the storey modules, these are formed by two halves 61, 62 of the storey.

[0065] As the typical measurement of the spaces between the columns of buildings is 66 metres or similar, it seems appropriate that a storey module 6 can be prepared in two half-sections 61, 62, measuring 36 metres each; these can be carried in a standard truck container, with no need for recourse to heavy haulage, which would increase the expense of the transport. Both halves 61, 62, once unloaded from the transport, are linked together by means of bolting once disposed side-by-side in their respective positions at the workface.

[0066] Next, the hoisting of the storey modules 6 is executed by means of cranes or winch engines, installed preferably at the apex of the columns (1-4), in collaboration with pull cables to hoist the storey modules 6 vertically upwards and in unison. To this end, the consecutive storey modules 6 are linked by means of cables (19).

[0067] In a preferred embodiment, the final storey module 6, or upper module 60, is that which corresponds to the roof of the building 101, and incorporates the corresponding enclosure elements.

[0068] FIGS. 1 to 7 portray phases of the stage of hoisting the storey modules 6 by means of elevation equipment, until their positioning in their definitive emplacements at their corresponding heights. FIG. 1 portrays the pile 5 of storey modules 6 disposed between the columns 1 to 4 of the structure 100. Motors 17 are disposed at the apex of the columns, in order to hoist the storey modules 6 upwards, by means of cables 18 linking the motor 17 to the first storey module 60, and by means of cables 19 linking together the different storey modules 6, in such a way that each hoists the next module immediately below.

[0069] FIGS. 2 to 6 portray successive phases wherein the storey modules 6 are hoisted simultaneously upwards until they surpass the brackets 8, in FIG. 6. The final phase is portrayed in FIG. 7, wherein the storey modules 6 have descended slightly, so as to remain resting, via the beams 10, on the corresponding brackets 8 of the columns (1-4). Below, with regard to FIGS. 18 to 24, a more detailed explanation of the execution of this support and the joining of the storey modules 6 to the beams (1-4) is given.

[0070] FIG. 8 is a plan view of the disposition of a storey module 6 once hoisted, deposited and anchored to the vertical structure.

[0071] FIG. 9 portrays a partial cross-sectional view of the composition of an example of a storey module 6 for a pair of regular storeys, while FIG. 10 is an analogous view portraying a storey module 60 corresponding to the flat roof of the building.

[0072] In both FIGS. 9 and 10 it may be seen that the storey modules 6, 60 feature slabs 7 which include a main load-bearing girder or beam 10, and secondary joists or stringers 15. The beam 10 may be a HEB-, IPE- or IPN-profile or other metal girder, and the stringers 15 may be of any type, for example cold-rolled metal C or Z profiles, or even HEB, IPE, IPN or other laminated profiles. In the storey module 6, 60, the installation of metal, plastic or other channelling 21, 22 for the passage of electrical, telecommunications, lighting installations and other utilities, and a number of pipes 23 for the passage of fluids. It may also be seen in FIGS. 9 and 10 that the modules feature ducts 24 for ventilation and air conditioning.

[0073] A fastening profile 25 links the half-slabs 61, 62 of the module 6, 60 via the interior of an overlapping pipe between halves 61 and 62. This fastening profile may be seen slightly above the linking plates 26 of the two halves 61, 62 of the module.

[0074] At the extremities of the beams 10 a number of plates 11 and 11 may be seen; the function thereof being to link the storey modules 6 to the columns 1-4. A number of welded eyebolts 27 are provided for the hoisting system.

[0075] A water-repellent panel 28 seals the upper surface of the module 6 and also enables the supporting of the deck 20 of the storey, to be covered with the appropriate flooring material; parquet, tiling, PVC, etc.

[0076] Below the beam 10 there is an auxiliary structure forming a false ceiling 32, with thermal and/or acoustic insulation, and a number of false ceiling plates 31 cover inferiorly the module 6, 60, and may incorporate luminaires, diffusers, smoke detectors, water sprinklers, motion sensors, light sensors, or other installations related to domotics or the internet of things, all installed priorly at source. FIG. 16 portrays a perspective view of an example of this construction.

[0077] FIG. 17 portrays an example of a completed false ceiling, incorporated in the storey modules 6, 60, wherein an example may be seen of how the cooling and heating machinery 37, the junction boxes, cable trays 22 and the air ducts 24 with their diffusers 38 and return grilles 39, and the conduits for all the installations executed in any type of building 101, are all incorporated in the modules 6, 60 in accordance with the invention, thanks to a prior design for each project, or alternatively, they may be standardised. The storey modules 6 may be prefabricated according to the design required for each, so that when the modules are hoisted and fitted, the pathways of the installations follow the predesigned routes. Once the entire building 101 has been hoisted, the installations of each storey module 6 are connected so as to form the storey, and the passage of the cables may be commenced, by means of guidewires or cable lead-throughs priorly installed in the trays. All of the above simplifies greatly the work of the fitters.

[0078] In one variant (not portrayed), the primary girder or beam 10 is at the highest point, and the joists 15 and facilities are below.

[0079] In another possibility, the slab 7 may be supplemented, as required by calculations, with a metal composite deck filled with concrete, and to bear thereon the necessary flooring, with parquet, tiles, PVC, etc.

[0080] In the storey module forming the roof 60 in FIG. 10, it may be seen that the assembly is completed superiorly with enclosing elements, such as an insulating sandwich board 34, waterproofing 35 or water-repellent panelling 36 of the thickness required by calculation.

[0081] FIGS. 11, 12 and 13 portray three steps of the hoisting of the storey modules 6 of the structure 100 which incorporate protrusions or balcony modules 40, subsequent to their attachment to the main girders or beams 10. They may even be assembled with the definitive handrails or barrier. A plan view of the location of the balcony-modules 40 may be seen in FIG. 14.

[0082] To guide the hoisting of the storey modules 6, the columns (1-4) feature a number of protrusions 9 (FIG. 18) acting as a slide for a number of guides 11 disposed on one of the beams 10 of the storey modules 6 (FIG. 19). The guides 11 are formed from two plates 11 and 11 on the sides of the web of the beam 10.

[0083] To attach the storey modules 6 to the structure 100, the columns 1, 2, 3, 4 are equipped with a number of articulated brackets 8, especially designed to open for the passage of the storey module 6 on being pushed upward by the edge of a beam 10 of the latter, and adapted to spring back due to the effect of a return spring 12 when the storey module 6 has surpassed it in height. The structural girder or beam 10 of the module 6 is attached to the corresponding column 1-4 by resting the edge of the beam 10 on the bracket 9 and affixing the same by means of bolting the plates 11 and 11 to the protrusions 9 of the beams (1-4).

[0084] FIGS. 20 to 24 portray successive phases of how the resting and attachment take place. In FIG. 20, the storey module 6 is rising and is below the bracket 8. In FIG. 21, plates 11 and 11 on the edge of the beam 10 enter into contact with the bracket 8 and start to push the latter upward, against the action of a spring 12. In FIG. 22 the bracket is completely folded against the flange bf the column and the guide 11 is passing by the protrusion 9. In FIG. 23, the beam 10 ceases to push against the bracket 8 which, due to the action of the return spring, returns to its horizontal operational position. In FIG. 24, the beam 10 together with the storey module 6 are lowered onto the bracket 8, on which it rests and to which it is bolted. Welding may also be employed.

[0085] FIGS. 25 and 26 portray two possible methods for erecting the storey modules 6 of the building 101 when there is a plurality of modules 6 to form a common storey of the building 101, to be hoisted as one pile 5 for every 4 columns, to form the structure of the floor in FIG. 27, for instance. In this example, it is a question of hoisting 12 piles 5 of modules. In a first case (FIG. 25) the modules 6 of all the piles 5 are hoisted simultaneously, and in the second case (FIG. 26) alternate piles 5 are hoisted.

[0086] The walls 13 and faades 14 of the building 101 may be pre-installed on the storey module 6, as portrayed in FIG. 28, wherein a plurality of storey modules 6, hoisted and joined, may be seen.

[0087] In FIG. 29 a case is portrayed wherein the interior walls 13 and faades 14 are assembled on the upper part of the storey module 6, and subsequent to attaching the storey modules 6 to the columns 1-4, the walls 13 or faades 14 are raised and affixed to the structure 100, forming the walls 13 and faades 14 of the floor above.

[0088] FIG. 30 portrays the opposite case, wherein the interior walls 13 and faades 14 are assembled on the lower part of the storey module 6, and subsequent to attaching the storey modules 6 to the columns 1-4, the walls 13 or faades 14 are lowered and affixed to the structure 100, forming the walls 13 and faades 14 of the floor below.

[0089] Finally, FIG. 31 portrays a building 101 in accordance with the invention, having a reticular structure 100, with the storeys totally formed, with the faade 14 and wall 13 elements erected from the storey modules 6, and with protrusions or balconies 16 at some of the storeys.

[0090] The nature of the present invention having been sufficiently described, likewise the method for putting the same into practice, it is stated that anything that does not alter, change or modify the fundamental principle thereof shall be subject to variations in detail.
