Description

September 17, 2024 VIDAL Caterina VIDAL Jacopo TITLE NEW CONSTRUCTION SYSTEM FOR THE CONSTRUCTION OF DEPLOYABLE HOUSING MODULES AND MODULAR BUILDINGS DESCRIPTION This patent is related to the field of deployable buildings and modular and in particular concerns a new construction system for the construction of deployable housing modules and modular buildings. 10 The same applicant is the owner of patents WO2012 / 147031 and 102019000007114, concerning deployable modular housing units. This invention introduces important innovations for the construction of buildings with the deployment technique; such innovations can be so briefly illustrated: 15 1. the decomposition of the module into finite and variously aggregable elements between them: basic element, intermediate element (figure 1) and element of pitched roof (figure 2) and flat roof (figure 3); 2. the specialization of the modules based on their function: technical module (2) and surface development module (2a) (figures 4 / 5a); 20 3. the total tightness of the product to air infiltration and, where present, to Radon gas thanks to a new interlocking system of components structural (figures 6,7,8). The building, thus constructed, can be subjected to Blower Door Test; 4. the exclusive technique of immediate support of contact forms 25 with millimetric precision (figures 9,..,13); 2 17 / 09 / 2024 5. the use of brackets and hinges, some of which have an exclusive design (figures 16,…, 22a and figure 29); 6. the possibility of placing the modules side by side no longer just on the side long but also on the short side, offering designers countless solutions 5 floor plans (figures 23a, 24a, 24b and 25); 7. a new design of the wall extension element in the case of delivery of the forms in a “discomposed” manner (figures 27, …, 30); 8. the deployment of the pitched roof with the ridge pre-installed, the chimneys, any vent pipes, solar panels, solar tunnels or skylights 10 (figures 31, …, 64). This technique is also applicable for the creation of gable roofs in traditional buildings; 9. a new system of assembly of the internal walls (figures65, …, 79); 10. the adoption of a new deployment and external finishing technique of multi-storey modules without the use of scaffolding. This technique, limited to 15 building units consisting of ground floor, first floor and roof, flat or pitched, with a habitable attic, it reduces the construction site activity for delivery of the finished work in a few days; 11. the organization of the production chain no longer by finished module but by type of finite element, postponing the decision to a later time 20 composition of the module based on requests; 12. greater flexibility in the composition of the load for its transport and lifting; 13. the possibility of installing the modules, the structure being self-supporting, on any type of foundation, be it slab, screw, gabion, or caisson 25 floating or on stabilized and level ground; 14. the reversibility of structural walls, an important factor in the economy and in warehouse management by reducing inventory by 50%. The present invention is aimed at the construction of building structures deployable, modular and passive earthquake-proof systems built according to the standards 5 highest and 90% dry assembled in the factory according to rigorous quality control parameters. The aim of this invention is to minimize the impact, both in terms of time and costs, for the construction of the plumbing and sanitary system, electrical and air conditioning. To this end, it was strategic to concentrate more 10 of 80% of such plants in a single module, hereinafter referred to as module technical (2). It houses the bathroom complete with sanitary ware and pre-installed shower / bathtub, one side of the kitchen with its drain, one space dedicated to the washing machine and dryer, any stairs for access to the upper floors and all the technology for managing the electrical system, 15 air conditioning, the production of domestic hot water and any power supply of the building unit with solar panels. It follows that, in any building unit constructed with the technique of deployment, regardless of the surface, will have to be between the n modules of surface development (2a) have at least one technical module (2), real engine 20 of the house. 1. Breakdown of the module into finite elements that can be aggregated in various ways They Another purpose of this patent is the breakdown of a technical module 25 or surface development in elements so as to allow their union both in 4 17 / 09 / 2024 establishment than on the installation site, and this with simple operations fixing using common screwdrivers and wrenches. This innovation arises mainly from the need to: • offer greater compositional / architectural freedom to designers 5 and clients. The module is thus composed based on the volumes requests; • reduce the load to be moved on the construction site, considering that, not is always available, in the installation area, for details environmental constraints, a load-handling machine 10 “important”; • organize the production chain no longer by finished module but by type of element (base, intermediate or covering – Figures 1, 2 and 3) postponing the composition of the form to a later time based on the supply order. This choice ensures a more punctual 15 quality control, greater timeliness in delivery of the manufactured product in addition to a notable saving in terms of storage of the finished product, no longer organised by pre-assembled modules but for elements to be assembled; • greater flexibility in preparing the load to be transported 20 with a significant reduction in costs. Founding units of the renewed construction system for deployable buildings I am: figure 1, the basic / intermediate element (1a / 1a') equal in their composition with the variant, for the intermediate element, of the possible hole 25 scale (11e); 5 17 / 09 / 2024 figure 2, the pitched roof element (1b) with the variant of the possible stairwell (11e) in the case of a habitable attic; figure 3, the flat roof covering element (1c). Each element, dry assembled in the factory, is delivered finished in 5 all its parts according to standard production types or according to the customer requests; the systems are pre-tested in the factory. They are structural components of the basic / intermediate element (figure 1): a base plane or floor (11), two portions of walls (20,20'), two elements of bellows extension (50,50') or alternatively two elements of 10 extension (50a, 50a') figures 27, 28 and 30; the base plane or floor (11) it is also present in the covering element whether it is pitched (1b) or flat (1c), while the walls (20, 20'), whose height varies according to of the habitability of the attic, there are only pitched roofs. The superposition of these according to the order: basic element, element(s) 15 intermediate(s) (in case of multiple floors) and roofing element give rise to a module. A module will always consist of at least one element of base(1a) and a covering element (1b / 1c). 2. Specialization of modules based on their function 20 Another purpose of this invention is the specialization of the modules based on the their function: the technical module (2) and the surface development module (2a) (figure 5). The first is always to be present in the composition of a deployable house; it is the heart of the house. the second, as the name itself says, it is placed side by side, in one or more specimens to increase the surface area 25 of the property. The plant component in these modules is modest. 6 17 / 09 / 2024 connection of the electrical network and the air conditioning system between two or more modules are done by means of connectors of the known type placed in position always easily inspectable preferably from the outside as well as The drains are preferably also placed outside (figure 5a). 5 Figure 4 shows respectively a finished technical module (2) composed of a basic element (1a), an intermediate element (1a') with second bathroom and a folded 45° sloped roofing element (1b); figure 4a shows it same module deployed. 10 3. Sealing of the product against air infiltration Another aim is to guarantee the perfect sealing of the finished work against infiltrations. of air and, in the areas subject to it, to the radioactive gases Radon. This purpose was achieved by redesigning the structural components (floors, walls perimeter and skirts) no longer with the edges cut in continuous wire and the union 15 of the parts in contact, but milled / shaped so as to allow the union of the parts with interlocking connections. The building, thus constructed, can be subjected to the Blower Door Test. In particular, the base plane or floor (11) has (figure 6) a milling (11f and 11g) both along the entire side (11b) and on the short side (11a) the latter 20 in rear position (d); said millings (11f and 11g) are part of a interlocking joint system (figures 7 and 8) between the base plane (11), the side walls (20) and the facade walls (100) which can be placed indifferently or outside the long side (11b) of the base plane (11) (figure 7) or flush with it (figure 8) according to design and / or installation choices 25 production. 7 17 / 09 / 2024 Variant to the basic plan (11) is the case of an intermediate element (1a') placed on the vertical of an underlying staircase, in this condition the plane will have a hole (11e) (figure 6) of adequate size; similar what for the base plane (11) of the covering element (1b) (figure 2) in the 5 case of habitable or otherwise accessible attic. 4. Immediate support of the modules Another purpose of this invention is to be able to combine or overlap with millimetric precision, immediately, and without subsequent expensive interventions 10 maneuvers, one module or element to another. This objective was achieved with the formation (figure 6), on the long sides (11b) of the plane of base (11), in a position not to interfere (figure 1) with the elements of extension (50,50',50a,50a') 4 cavities (11d) wide and deep sufficient for the passage of a lifting sling (figures 9 and 10). 15 By sliding said trousers (60) inside the cavities (11d) it will be possible to match immediately with millimetric precision (figures 11 and 12) and without subsequent costly maneuvers, an element or a module to another by quickly taking off the trousers used for the movement of the module or single element. 20 This operation can be done only if the intrados of the base plane (11) is not in direct contact with a surface; that is, in only in case of screw foundation, gabion foundation or in any case (figure 11) in support on root beams (62); in the case where (figure 13) the base plane (11) whether supported on a foundation (63), it will be necessary to foresee during the casting phase, at the 25 formation of a double recess (61) of limited width and depth and 8 17 / 09 / 2024 enough to slide the trousers (60) inside it. As already stated, the aim of this invention is the creation, through the deployment technique, of a house with several floors, modular and passive which, as such, can be subjected to the Blower Door Test. 5 To this end, particular attention was also paid to the redesign of the vertical walls, shaped in such a way as to guarantee a total seal air infiltrations (figure 14). These walls are composed of the wall portions (20 and 20') and the extension elements (50, 50') or (50a, 50a') They have, on the short sides (20a), along their entire length, a milling (20b 10 and 20c), visible for example in figures 14 and 15, one of which faces the inside and the other towards the outside. Once the modules are placed side by side and unfolded, at the point of contact between the said walls, a recess will be created (figures 11 and 12) where a pillar (155), the wood or steel, useful for giving further rigidity to the structure; other examples in the figures 15 92, 92a, 96, 96a and 106, 106a, 113, 114. A double milling (20e) is also present on the long sides (20d) in position set back from the sides (20a) and of length equal to the length of the brackets (3, 4b) and the hinges (4) and of a depth equal to their thickness (s) . The brackets and hinges will be sized so as to leave between them 20 a distance (dd) (figures 14 and 15) sufficient to create a possible gap to connect an element, be it basic or intermediate, with another adjacent one. The wall (20) and the wall (20'), in figure 14a, are in shape and size equal; upon installation, one is rotated 180° on the major axis 25 compared to the other. Figure 15 shows the same wall (20) represented in 9 17 / 09 / 2024 figure 14 but with the millings on the short sides (20a) facing the same direction; in this case too the wall (20) and the wall (20') are the same but one rotated 180° along the minor axis with respect to the other. The wall in figure 14 is used in the assembly of elements that 5 make up a head / tail module (figure 14a); the wall in the figure 15 is instead used in the assembly of elements of a module included between other modules (figure 15a). 5. Brackets and hinges 10 Another aspect of this patent is the design of brackets and hinges, used for fixing and rotating the fixed and moving components of the modules, with a simple design, which allow for perfect sealing air infiltrations. Figure 16 shows the position of the brackets used to fix the walls (20 and 15 20') at the base level (11). Specifically, these brackets are available in three variants (figures 17, 18 and 19): A) the first (3) (figure 17) is a bracket made according to the known art, made up of a U-shaped press-formed sheet metal with an adequate number of holes on the wings (30) and on the bottom (31). This bracket (figure 16) must be 20 fixed to the base plane (11) in the appropriate milling (11g) in position set back (d') from the edge (11b) and aligned with the respective milling (20e) present on the wall (20 and 20'). The use of this bracket is planned on modules preferably composed of a basic element and one of coverage, that is, in a situation where there is a risk of tearing 25 significant, in the deployment phase of the elements, is reduced. 10 17 / 09 / 2024 B) The second bracket (3a) (figure 18) is to be used on composite modules from one or more intermediate elements, considering it more probable - the thing It depends on the skill of the person in charge of operating the crane - the risk of tearing during deployment, given the greater 5 mass to be moved. The latter, identical in shape to the bracket (3)(figure 17), presents (figures 18 and 18a), welded or screwed into the base thickness (31), some threaded rods (32) in diameter suitable for the function, longer than the thickness (s11) of the base plane (11) and sufficient to allow, on the intrados 10 of the base plane (11) the locking, with nut (34), of a counterplate (33) and if a separating element is provided thin and flexible (35). C) The third bracket (3b) (figures 19 and 19a), identical in shape to the bracket (3a) is used to fix the walls (20 and 20') to a plane of 15 base (11) of an intermediate element (1a') or covering (1b, 1c). This bracket does not require the counterplate (33) as the bars threaded (32), passing through the underlying wing of the hinge (4a), they will be blocked with nuts (34). Figure 20 shows the position of the hinges whose function is to 20 join: A) with hinges (4) (figures 21,21a,21b,21c): - the walls (20 and 20') with the wall extension element (50,50') allowing it to rotate 90°; - the two portions of walls (50,51 and 50',51') that make up the 25 wall extension elements (5.5') allowing for a 11 17 / 09 / 2024 180° rotation; B) with hinges (4a) (figure 22, 22a,22b) - the wall portions (51, 51') that make up the elements of extension of the walls (5.5') with the intrados of the floor 5 base (11) of an intermediate element (1a') or covering (1b, 1c). - the wall portions (50a, 50a') with the intrados of the floor base (11) of an intermediate element (1a') or covering (1b, 1c). These hinges are all equipped with a removable pin (44) (figure 21a) with pin closing (45) and relative cotter pin (46). 10 The hinge (4), figures 21 and 21a, has wings (a) with a C-shaped profile and with a adequate number of holes for fixing; on the walls (42) of the C-profile threaded rod “stumps” (43) of length are welded / screwed sufficient for insertion, once the element has been deployed basic or intermediate, of a plate (47) useful, once the nuts (48) have been screwed on 15 (figures 21b and 21c) to the hinge block. Figure 22 shows the hinge (4a) used to join the element of extension of the walls (51,51',50a,50a') with the intrados of the floor base (11) of an intermediate element (1a') or covering (1b, 1c). This hinge has a wing (a) with a C-shaped profile equal to the previous hinge (4) and 20 a wing (b) with a flat profile and an edge (49) of a thickness useful for maintaining, a closed zipper (figure 22a), the two hinge wings in parallel position also compensating for the thickness of the nut (34) (figure 19a) present at their internal; neoprene or rubber gaskets (49a) are glued on the external surface (41) of the wing (a) along the entire length of the hinge. 25 With the base plane (11) and the walls (20 and 20') are structural components of the 12 17 / 09 / 2024 construction system of which the present invention includes the extension elements of the walls (5.5') (figure 23). These elements are composed of two portions equal in wall (50 and 51 / 50' and 51') having, in shape and position, the same millings present on the walls (20 and 20') (figure 25). Each portion of the wall 5 has length equal to the length of the side (11a) of the base plane and width (h2) variable in relation to the internal useful height of the rooms of the building which will be realized (figure 26). The same module can have between the floors different heights. Alternatively, these extension elements can be replaced with 10 the elements 50a, 50a' of figures 27, 28 and 30. 6. Arrangement of modules in length and width Another purpose of this invention is to allow, in a rapid and functional way not only the juxtaposition of the modules by their width but also by the 15 length. The wall extension element (5.5') shown in figure 23 It is used in the case of modules placed side by side due to their width (figure 23a); the extension element of the walls (5a,5a') represented in figure 24 will instead be used if you intend to create a window or 20 in the case of modules placed side by side for their length / depth (figure 24a) to be connected by opening a door. Of course, combinations where three modules are present are also possible. placed side by side in both width and length (figure 24b). The length of the wall portion (500 / 511) shown in figure (24) is equal to 25 to the length of the side (11a) of the base plane (figure 25) subtracted width of the passage (dd) that you intend to create, divided by two. The set of combinations is also possible when using the elements of extension 50a and 50a' with a similar process. Figure 25 shows the possible combinations of the side walls. 5 of the basic (1a) and intermediate (1a') elements: blind (6) with window hole (6a) with access gate(6b). There are therefore countless solutions typological, dimensional and architectural deriving from the free aggregation of multiple modules with the possibility of being placed side by side on all sides. The width (h2) of said wall portions (figure 26), once defined 10 the useful height (H) of the compartment is given by the formula h2=(H+sp+sc-h1) / 2 where: (sp) is the thickness of the floor measured from the extrados of the base plane (11) at the level of the finished floor, (sc) is the thickness of any false ceiling measured from the intrados of the base plane (11) to the edge of the finished ceiling and (h1) is the height of the wall (20 / 20'). The maximum width 15 (h2) of a portion of the wall (50,51 / 50',51') is equal to half the distance (L) between the two walls (20 and 20'). 7. Decomposed modules Another purpose of this invention is, in case, for various reasons 20 (transport optimization, handling difficulties at the place of installation, impossibility of finding a machine on site for the lifting materials of adequate capacity), it is not possible to deliver on site the "composed" modules and therefore it is necessary to opt for delivery separate the various elements (base, intermediate / s, covering), replace 25 the wall extension element (5.5') represented in figure 23 14 17 / 09 / 2024 with the extension elements (50a, 50a') represented in the figures 27,28 and 30; these elements are completely identical in shape and length to the walls (5, 5') but with a width equal to the sum of the width of the portions of wall 50+51 and 50'+51' i.e. equal to 2b (figure 26). 5 These extension elements (50a, 50a') are hinged to the extrados of the base plane (11) of the intermediate or covering element through the hinges (4a) figure 22. When joining the intermediate element (1a') to the base element (1a) or, the covering element (1b) to an intermediate element (1a'), the portions of 10 walls (50a, 50a') are freed and brought into a ready vertical position to be inserted and fixed on the H-brackets (4b) (figure 29), made according to the known art and already previously installed on vertical walls (20,20') figure 30. The use of the wall portions (50a,50a') maintains the possibility of 15 place the modules side by side according to their length / depth (figure 24a / 24c) allowing the opening of a window hole (6a) or door hole (6b) figure 25 8. Foldable and finished pitched roof in all its parts Another aim of this invention is the creation, in the factory, of a 20 deployable double-pitched roof system, finished in all its parts with ridge, gutters, any ventilation or smoke release pipes, panels pre-installed solar panels, skylights or solar tunnels, etc. This roof system offers several possibilities for use: - it can be hinged to the covering element shown in figure 2, 25 made with the same components as the basic or intermediate module 15 17 / 09 / 2024 that is: a base plane (11) with or without hole (11e), two walls vertical (20, 20') whose height varies according to the habitability of the attic room; in this case the level of a first slope (11h) will be hinged on one of the two vertical walls (20,20') while the top 5 of the second flap (11i), the shorter one will be hinged to the plane of the first slope (11h) on the ridge side. The shortest length of the slope (11i) will be compensated by making the wall (20 or 20') without the hinges a “support foot” (11L) of suitable size. The skirt (11i) will be fixed to the vertical wall (20 or 20') using brackets 10 (11m) made according to the known art. - It can be fixed to vertical walls (20,20') after its deployment on site (figure 44). In this case the aquifers will have same length and therefore it will not be necessary to prepare of the “support foot” (11L). 15 - it can also be used in conventional construction (figures 55, …, 58). The construction technique of this roof system, whether it is hinged slopes to the structure or in support of it, it is the same. Variables in their production are (figure 31): 20 - the distance between the supports (D), in the case of a building roof conventional; - the overall length of the roof, in the case of a building roof conventional; - the slope of the aquifers (in the example: the aquifers have a slope of 30°); 25 - the type of finish (in the example: the finish is corrugated sheet metal); 16 17 / 09 / 2024 - whether the roof is ventilated or not (in the example: the roof is ventilated); - whether or not tie rods are fixed (in the example: the tie rods are pre-installed); - the exact location of any ventilation or smoke release pipes with exit already prepared on the ridge; 5 - the type of material and the thickness of the insulating panels required by the installation climate zone; - the exact positioning of any skylights, solar tunnels and / or solar or photovoltaic panels. This roof system, obviously created for the deployable construction referred to in 10 This patent, can be used (figure 31) on any type of manufactured, by way of non-limiting example, in brick (M1), in wood laminated or frame (M2), etc. The width of a roof element, figure 33 (101c), is, for containment of costs, preferably tied to its transportability by road as 15 ordinary or exceptional unassisted load (according to the regulations of the destination country). However, the possibility of create roof elements of even greater width. The type of finishing of the skirts will be in a range of products selected by the manufacturer or chosen by the customer; the only condition is that the finishing product 20 can be securely fixed to the roof structure. The roofs can also have the tile finish in which case they will be delivered without finished but waterproofed ready to accommodate the laid tiles obviously after their complete installation. For the deployment of a covering element (figure 2) or of the individual 25 layers (figure 32) a material lifting machine will be needed, 17 17 / 09 / 2024 a 4 or 2 point sling, a pulling system made with ropes. In the case of use in conventional construction, after the support of the roof elements, any remaining uncovered roof will be compensated with a wildcard cover element (custom width). 5 The slopes may be either symmetrical or asymmetrical. This construction system allows, after the placement of the roofing elements, installation of the lifeline kit (fall arrest system). The skirts (figure 32) will be delivered folded to the place of installations already finished in all their parts with ridge (112) pre-installed and, 10 as per request, the gutters (110) and any ventilation pipes and / or smoke release (115a), solar panels (118), etc. In case the flaps are delivered already unfolded, figure 93b, and ready for installation, the ridge hinges, figure 39 (114a, 114b) they can be replaced by brackets made according to the known art or by screws. 15 This construction system presents innovative elements not so much in the stratigraphy of the aquifers, which uses current knowledge, How much: - in the drawing of the structural element of the roof, figure 33 (101), preferably made of laminated wood or frame which has 20 on the sides (101a and 101b) opposite the ridge and the gutter, of the millings with a chamfer (111a) near the attachment of the full element (101c), capable of allowing, if it is a 2-point balancer was used to move the flaps of attachment, the passage of the lifting strap, ensuring 25 so the contact flanking; 18 17 / 09 / 2024 - in the reduced volume during transport as the layers, pre-assembled, they travel folded up on themselves with the possibility of be transported both vertically (figure 50) and horizontally and in the latter case also overlapping (figure 54); 5 - in the ridge element (112), figures 31, 32 and 35 fixed firmly to the structural element of the skirt (101) by means of brackets (113) of the known type; - the possibility of inserting any pipes into the thickness of the layer ventilation or smoke release (115), figures 34 and 36 and their 10 exit from the ridge (115a). These roof elements may also be, as already mentioned, of the type ventilated (figure 32) or non-ventilated (figure 39), contain inside the structure of any ventilation or smoke release pipes (115) with outlet already arranged on the ridge (115a), insulation in the required thickness (103) 15 with, if applicable, the installation of tie rods, skylight or solar tunnel, as well as solar or photovoltaic panels (118) already connected to each other. The ridge element (112) figure 34 can be pre-installed indifferently on one of the two slopes, according to the indications of the client / designer; in the slope with the ridge element pre-installed, 20 in the thickness of the insulating panels (103), the panel(s) can be fixed portion / s of pipe (115), useful for venting fumes or vapours, with direct exit from the ridge (115a). If it is necessary to insert it on this slope or on the slope without the ridge element of a smoke vent pipe or unplanned vapors (116), this can be inserted later 25 the juxtaposition of two roof modules, inside the recess (117) which is 19 17 / 09 / 2024 came to form. Figures 35 and 36 show the stratigraphy of a ventilated aquifer with the pre-installed ridge element: 101 - supporting structure of the roof made of laminated wood or frame; 5 102 - vapor barrier cloth; 103 - layer of insulating panels of the required type and thickness; 104 - containment strip; 105 - breathable waterproof sheet; 106 - frame of slats for ventilation; 10 107 - OSB panel or similar; 108 - gutter stop element; 109 - gutter support bracket: 110 - gutter; 111 - external finishing; 15 112 - ridge element; 113 - bracket for attaching the ridge to the supporting structure of the roof; 114 - hinge system for folding and unfolding the flaps; 115 - pipe for venting fumes and / or vapours; 115a - vent pipe exit from the ridge. 20 With reference to figures for example 31 to 45, the new roof includes a pair of flaps A, B, hinged together at one of their points side, or ridge side, and intended to be arranged inclined and supported between two supports, which could be the vertical walls of a module underneath but also two masonry walls according to traditional construction. 25 Each slope A, B includes at least one panel 101 (figure 33). On a 20 17 / 09 / 2024 side, or ridge side 101c, of said panel 101 is rigidly constrained, for example by means of brackets 113 (figure 35), a ridge element 112, i.e. an element with a predominantly longitudinal development, intended to identify the ridge of the roof, and whose section (figure 37) includes: 5 - a first side 112a attached and tied to said ridge side 101c of a layer A; - a second side 112b, contiguous to said first side 112a, intended to be placed against the ridge side 101c of the second slope B when the roof is correctly deployed; 10 - at least one third side 112c, 112d intended to be facing the top, identifying the upper surface of the ridge. The first and second sides 112a, 112b are inclined towards each other according to of the inclination that the slopes will have. The shape of the ridge element 112 It is therefore a function of the configuration of the finished roof. 15 Figure 37 shows various types of ridge whose geometry varies in relation to: - slope of the slopes; - thickness (s1) of the roof layer, measured from the intrados of the structural element of the aquifer, figure 31, at the most extreme point 20 to the finishing element; - whether it is a ventilated or non-ventilated roof. Figure 37a shows the cross-section of a non-roof ridge element. ventilated with a 30° slope; figure 37b shows the section ridge element for ventilated roofs with a 30° slope; 25 figure 37c the section of a ridge element for a non-ventilated roof with 21 17 / 09 / 2024 slope of the slopes of 45°; figure 37d shows the section of an element of truncated cusp ridge for non-ventilated roof with slope of 60° and figure 37e the section of a ridge element with a cusp for a roof not ventilated with a 60° slope. 5 The ridge element (ventilated) 112 (figure 38), the structure of which is described below as an example but not binding, presents a appropriate number of frames figure (119), in relation to the length x of the ridge and whose geometry varies according to the slope of the roof. The frames, figures 37, 38a, are composed of a panel (120) in the required shape 10 from the type of roof slope, with a hole (121) in the centre to ensure any ventilation or passage of cable ducts, framed with strips of suitable section (122) on which the panels will subsequently be fixed perimeter (123a,123b,123c) of length equal to the length x of the ridge. The upper part of the ridge will then be protected with a cape (124) 15 compliant with the type of finish used for the skirts. Figure 38a shows the lateral openings, along the entire length of the ridge, in the case of a ventilated roof. Figure 39 shows a non-ventilated roof module with a 30° slope and with pre-installed tie rods (125). Their bulk requires, as evident in the figure 39a, a greater spacing between the intradoses of the slopes (126) 20 which is obtained using a type of hinges (114a) presented as exemplary but not binding. Similar detachment between the intrados of the slopes can be motivated for the pre-installation of a false ceiling. In case it is not necessary to distance the intrados of the slopes (126), the hinges will be of the type in current use (114b). Figure 39b 25 shows the rotation movement of the flaps (A,B). 22 17 / 09 / 2024 Figure 40 presents a deployed roof module for ventilated roof with slope of the slopes at 30°, with photovoltaic panels (118) on one slope and chimney for venting smoke and / or vapours (115a). For anything not yet mentioned, highlights: the airtight gaskets (127), the cavity of 5 ventilation (128), the cable duct (129) to connect the photovoltaic field to the appropriate switch present in the building and the exhaust elbow of the gutter (130) also pre-installed. Figure 40a shows the same roof module but folded down. Figure 41 presents a deployed roof module for ventilated roof with 10 slope of the slopes at 45° Figure 41a shows the same roof module but folded. Figure 41b shows the rotation movement of the flaps (A,B). Figure 42 presents a deployed roof module for ventilated roof with 60° slope of the roofs and truncated cusp ridge. 15 Figure 42a shows the same roof module but folded. Figure 42b shows the rotational movement of the flap. Figure 43 presents a deployed roof module for ventilated roof with 60° slope of the roofs and cusp ridge. Figure 43a shows the same roof module but folded. Figure 43b shows the 20 rotation movement of the flap. Figure 44 shows the slopes of a roof already unfolded. To ensure their stable opening, using a 4-point balancer during the positioning phase attachment points (131), are fixed, temporarily, and until their correct locking on the brackets for quick housing (132), two 25 telescopic props (133). Figures 43b and 43c show two variants of brackets (132a, 132b) for quick mounting of the roof module on a brick wall or on a concrete wall solid wood or frame. Figure 45 shows a deployed roof module with pre-installed also 5 solar tunnels (134) or skylights (135). Figure 45a shows the same cover module but folded. Figures 46, …, 50 show the assembly sequence of a covering element. In detail, figure 46 shows the slope (A), with ridge (112) 10 pre-installed, placed vertically and supported on the heads (136), duly shaped, on which a steel tube clamp was fixed with at the end an external and internal thread (137). Figure 47 shows the addition of the aquifer (B) to the aquifer (A) by means of the use of a 2-point attachment sling. 15 Figure 48 shows, once the apron (A) has been placed side by side with the apron (B), the insertion of the pin (138) of the hinges (114). Figure 49 shows, once the hinge pin has been inserted, the insertion of the movable heads (136) on the steel tube (137) and the placing in a vice completely by means of a nut (139). At this point (figure 50) the 20 cover module is ready to be stored or transported, to destination, upright. For its movement (figure 51) they will be temporarily screwed, at the top of the steel pipes (137), internal thread, two eyebolts (140). These eyebolts will also be used to proceed with the movement or the 25 overturning (figure 52) of the covering element for its possible 24 17 / 09 / 2024 transport in a horizontal position (figure 53) or to start the activity on site of module deployment. Both during transport and storage, the flaps, thus assembled, can be placed on top of each other (figure 54). 5 Figures 55, ..., 58 show the phases of laying the said layers on the structure load-bearing of a building, whether it is of the deployable or conventional. Once the flaps have been deployed, before their transfer, they are temporarily fixed at the end and held until they are correct 10 positioning and locking on the brackets (132a / b), two telescopic props (133). The movement of the flaps can be done preferably using a 2-point attachment beam (figures 55 and 56). Fix the skirts to the brackets (132a / b) remove the telescopic props (133) and complete the roof 15 with the installation of the connecting capes of the slopes (141), of the element of ridge connection (142) and welding of the channel connection joints gutter (143). In case you choose to collect rainwater in the central point of connection of the slopes, as an alternative to the joints of fitting, the exhaust outlet will be installed. 20 Figure 58 shows the finished roof. Figures 59, ..., 64 now show the deployment of the layers, one of which hinged to a vertical wall (20, 20') of a roofing element; and skirts, in the rest position (figure 59) are kept in a horizontal position from some props (71) fixed inside the edges (11b) of the base plane 25 (11); the flaps A and B are also locked together by means of plates (72). 25 17 / 09 / 2024 Once the lifting of the slopes has begun (figure 60), the props are removed and, once the slope of the slopes will allow slope A to oscillate freely, the locking plates (72) will be removed bringing it towards the opposite vertical wall (20') (figure 61). This 5 movement can be done either with the aid of pistons (73), as in illustration, or with a pulling system made with ropes. Once brought the slope A on the vertical of the support brackets (11m) (figures 62 and 63) will be lowered until it rests on the foot (11l) and then definitively fixed to the brackets (11m). 10 Figure 64 shows the roofing module with the slopes deployed completed. 9. Assembly of the internal walls Another aim of this invention is the particular technique with which they are 15 internal walls were created in the building structures built with the technique of deployment, as per this patent. These internal walls are made of two parts (figure 65), a lower part (pb ) is fixed firmly to the base / floor plane (11) and to its tenon (144) fixed to the wall (20 / 20') and a high part (pa), inserted, once completed 20 deployment of the basic (1a) or intermediate (1a') element, between the guide (145), previously fixed to the extrados of the upper floor (11) and the portion of beam (146) of the lower wall (pb). The structure of the internal walls is of the frame type made according to the art note, with wooden beams or boards of modest section or steel profiles, 25 insulating material in the cavity and covered on both sides with panels 26 17 / 09 / 2024 wooden or plaster base. The lower part (pb) of the walls (figure 66), at the time of their installation, they are complete with all the distribution systems, be it electrical, water and air conditioning; on the bathroom walls are 5 pre-installed modules (147) for quick and punctual installation of sanitary ware. The design of the structure, as well as the thickness of the wall varies in relation to the type of networks present within it and obviously to the different distribution of internal spaces. In the case of a wall (figure 66) without drains, its structure will be of the type 10 pbA, that is made with wooden beams or steel profiles, in the case instead of the wall where there are drains the structure will be of the pbB type, that is mixed, composed of beams and planks. The connection point of all the drains (figure 67) is preferably placed outside the wall (20 / 20') of the technical element, so as to ensure a 15 easier intervention in case of failure; venting the exhaust pipe (115s) is also already pre-installed, for the entire height of the wall (20,20'), just as the end part of the vent is pre-inserted into the thickness of the slope with direct exit on the ridge (115as). It will therefore be sufficient to join the two parts to have the column ready for use. 20 Also on the outside there is a connector system (148) to connect, between two or more modules, the electrical and air conditioning system (replicating, a example title, the same methodology used to connect the carriages railways). Figures 68, ..., 79 show the stages involved in assembling a wall on 25 a basic or intermediate element (1st / 1st') and its completion at 27 17 / 09 / 2024 deployment has taken place. Specifically, figure 68 shows the approach of the lower part of the wall (pbA), without cladding on one side, ready to be fixed to the base plane (11) and the tenon (144) placed on the side wall (20 / 20'); the 5 figure 69 shows the fixing to the base plate and to the tenon; the figure 70 fixing the cladding panel (149) raised from the plane basic (11) to allow the exit, on the floor, of any network pipes electric or water; figure 71 shows the fixing of the panel to the tenon opposite side covering. 10 Figures 72, 73, 74 show, once the deployment of the element has been completed, basic or intermediate (1st / 1st'), the start of the completion activity of the wall with fixing on the extrados of the upper floor slab (11) of a guide (145) using two stadia (figure 75) designed for the correct alignment of the guide (145) to the underlying beam (146) of the 15 lower wall (pb). These stadia (figure 75) have a inverted L-shaped vice (150), with the short side measuring less than the wall thickness and on which a pin is welded that slides along a slot (151) whose length is greater than the long side of the vice; on the side 20 opposite of the staff, to tighten the vice to size, a wing nut or similar (152) is screwed to the pin. In the upper part of the staff is welded an inverted shelf (153) designed to support the guide (145). Figure 76 shows the push insertion of the high wall part (pa) up to in contact with the tenon (144'). Once the insertion is complete, we proceed to its 25 final fixing (figure 77). To ensure perfect flatness over time 28 17 / 09 / 2024 of the wall is inserted (figures 78,79), on the opposite side to the tenon, in the cavity created by the overhang of the finishing panels, a beam or a stud in galvanized steel (154). 5 10. Technique for unfolding and finishing the modules without the use of scaffolding. Another purpose of this invention is to realize the deployment of the modules and the external finishes of the building unit without the aid of scaffolding but with the only use of a material lifting machine, of a balance beam with 2 and / or 4 attachment points, of a pulling system made with ropes, of a 10 scissor platform or common scaffolding. This deployment can be done in several ways depending on how they are delivered the modules to the installation site, i.e. in the configuration composed or decomposed. A module can in fact be delivered with the basic element (1a), 15 possible intermediate (1a') and covering (1b) already assembled (figure 80), or, for various reasons (transport optimization, difficulty of handling at the installation site, impossibility of finding the place a material lifting machine of adequate capacity) delivered separately, i.e. in the disassembled configuration (figure 93). 20 Figures 80,..., 92 illustrate, by way of non-limitative example, the phases of delivery, installation, deployment and finishing of a housing unit approximately 100 m2 of floor space, divided into ground floor, first floor and attic habitable, with a 45° roof, installed, by way of non-limiting example, on foundation with a platform and composed of two modules, one technical (2) and one 25 surface development (2a). 29 17 / 09 / 2024 For the unassisted exceptional transport of the modules (2, 2a) and of what two tractors with will be sufficient to complete the building unit low bed trailer (figure 80). In detail they show: 5 Figure 81 the positioning and juxtaposition of the two modules (2 and 2a) on the platform, using a mobile crane and a 4-point lifting beam; Figures 82 and 83 show the deployment phase of the covering element (1b) using a 2-point attachment sling. Figure 84 shows the finished covering element, complete on three sides of the 10 external finishes (156), made with pre-shaped and pre-finished panels produced in the factory and fixed, considering the reduced height (H) from the worktop countryside, less than 300 cm, with the simple aid of a scaffold or a scissor lift or similar. Once this phase is completed, the deployment and the 15 completion of the covering element of the side-by-side module (figure 85). From now on, further deployment of the module will be possible occur using either a mobile crane with a 4-point lifting beam hooking (figure 86), or with the aid of hydraulic pistons operated by a control unit (CO) (figure 87); the following figures illustrate the deployment 20 of the module assuming the use of hydraulic pistons. Figures 88 and 89 show the deployment of the intermediate element (1a') while figure 90 the completion of the external finishes, made always using either a scaffold or a scissor platform or similar. Figures 91 and 92 show the analogous operation done for the deployment 25 of the intermediate element of the adjacent module. The same figure 92 shows, ready to be fixed in the appropriate slots, the pillars are to the stiffening of the structure which can be indiscriminately made of wood or in steel and shown in detail in figure 92a. Figure 93 shows the completion of the external finishes of the floor 5 intermediate always made using either a scaffold or a platform scissors or similar. A similar procedure will be followed for the deployment of the basic elements. using either hydraulic pistons or a four-point balance sockets (figures 94, 95, 96, 96a). 10 Complete the external finishes of the building unit (figure 97), or prior to completing the finishing touches, we will proceed (figure 98) to fixing of the connecting elements between the slopes of the modules: ridge (142), cape (141) and gutters (143). Figure 99 shows the synthesis of a building, of approximately 100 m2 of floor space, 15 finished in all its parts, consisting of ground floor, first floor and attic habitable entirely built without the aid of scaffolding. Figures 100, …, 116 show, by way of non-limiting example, the delivery, installation, deployment and finishing phases of a unit housing of approximately 70 sq m of floor space, divided into ground floor, first floor and 20 non-habitable attic, with a 30° roof and composed of two modules, one technical (2) and one of superficial development (2a) whose basic elements, intermediate and cover are delivered, for the reasons mentioned above, (transport optimization, handling difficulties at the place of installation, impossibility of finding a machine on site for the 25 lifting materials of adequate capacity) separately. For the unassisted exceptional transport of the modules (2 and 2a) and of what two will be sufficient to complete the building unit tractors with flatbed trailer (figures 100 and 100a); in the case where the covering element is delivered unfolded and ready for use 5 the installation (figure 100b) will require an additional truck for the elements of external and internal finishing (156). The installation activity of the building unit begins with the transfer and positioning of the base (1a) and intermediate (1a') element of a module on the foundation, in this case a slab; once the base (1a) has been fixed to the 10 platea we proceed to the harnessing of the intermediate element (1a') and its lifting using a 4-point lifting beam (figures 101 and 102). Unfold the extension walls (50a and 50a') and align them with the ones below brackets (4b) (figure 103), once everything is lowered we proceed to fix them (figure 15 104); the installation of the base element will be carried out in a similar way and intermediate of the second module (2a) (figure 105). Figures 106 and 106a show the pillars (155) ready to be fixed to the walls in the appropriate slot; once fixed, it will be possible to install the external finishing of the ground floor (figure 107) and, at the same time, also the 20 external finishing of the two covering elements (1b) with the closing of the gable (figure 108) using pre-finished panels made in the factory (156). Now, with a procedure similar to what was done for the intermediate elements, will proceed to lift and position the 25 covering elements (1b) and their fixing to the underlying brackets (4b) (figures 109, …, 113). Figures 114 and 115 show how much more is needed to finish the roof in all its parts, that is, a pre-shaped cape for the connection of the skirts, of the ridge and gutters. 5 Once the roof is completed, all that remains is to finish the external walls of the intermediate floor (figure 116) using, considering the limited height (H) from ground level, less than 300 cm, or a scaffolding or a scissor lift. Therefore, with reference to the preceding description and the enclosed tables, 10 express the following claims.
