Building system for cladding with prefabricated elements

Abstract

The building system is mainly applicable to the civil buildings, houses, shops, offices and so on. It is applicable to buildings with a concrete, metal or wooden bearing structure; it's not applicable to buildings with masonry walls bearing structure. The building system is conceived to realize versatile cladding wall, anti-seismic, fire-resistant and very insulating, with a new technic that assures a considerable saving of time and money. The cladding wall are realized through the assembly of prefabricated modular elements, in adherence between them, flanked side by side and overlaid. It's possible to fill all the possible spaces between the pillars by choosing properly the elements. Differently, the space between the planking level and the beam's intrados of the upper floor is filled with two lines of elements. Thereupon, the applicable law usually establishes standard heights; however, even if the height of the elements isn't corresponding to the height to fill, the space can be filled just changing the thickness of curb where the first line of elements is going to be installed. By this building system is easy to assembly the cladding walls, eliminating a lot of interventions necessaries to realize the traditional cladding walls, shortening the execution times, also because there are no interventions like to wall up, to plaster, to skim, to paint and so on, and shortening the processing time, because they don't need mortars, smoothing materials nor plasterworks' drying and desiccation time. The elements, assembled and linked among them and with the bearing structure's backbone, form a framework with its own stiffness. So that the elements form a sub-framework in relation to the main framework (the bearing structure of the building). It's possible to install thermal insulation and soundproofing panels on this sub- framework, followed by the installation of closing panels and fagade finishing layer. This way, it's possible to avoid the negative effect of "thermal bridges" and the sound insulation between the external and internal environment is effective. In the thickness of elements, it's possible to place utilities' pipelines and ducts. The building system eliminates demolition work, opening traces, closing tracks, plastering and so on. Inside the single element is possible to install every external and internal window fixture, like doorways, windows, French windows, interior doors. The element has constructive regularity and high degree of accuracy, so that it performs the function of counter-framework, avoiding the need to provide and install counter-frameworks in the building site. All the elements have holes with several uses, including the goal to equip the external sides with photovoltaic panels and solar thermal panels; the sub- framework is suitable to support ventilated walls. The elements are produced in limited series. They are conceived both reinforced concrete elements and metal or wooden elements. The building system is also suitable to performs the function of room dividers, dividers between different flats, and so on. Moreover, the elements are also suitable to other uses like: for example, parapets, railings, pedestrian barriers, bollards, guardrails, framework for niches to locate the utilities, and so on.

Description

1. TECHNICAL FIELD

[0001] The technical field is mainly the civil buildings, houses, shops, offices and so on. This system consists of build cladding walls, partitions walls, parapets, fences, room dividers and vertical closures through specific elements; the system is conceived for reinforced concrete structure buildings, but it can be used also for the other kind of structures of the buildings.2. BACKGROUND ART

[0002] Cladding walls can be realized through many ways, which could be grouped in two categories, the rubble-filled cladding walls and the "sandwich type" ones.

[0003] Regarding the first category (rubble-filled cladding walls), the need to realize the vertical closures in the framework of a building with reinforced concrete bearing structure, which also have to provide thermal insulation and soundproofing, is accomplished through two parallel masonries with bricks or Siporex elements and so on. In the middle, there are materials for the thermal insulation (fiberglass, polystyrene panels, air pockets and so on). Furthermore, there is the need to plaster, skim and paint the external faces of those masonries or, as appropriate, to tile the walls in the internal side and to stick stone material in the external side.

[0004] To fulfill the needs to install facilities, pipelines and installations, you have to open the ducts, put into the corrugated pipes and then close the ducts with special mortars. Therefore, there are a lot of interventions to do and a lot of materials to use to realize the rubble-filled cladding walls. This system, then, involves the necessity to employ skilled labors to align the masonry, for its verticality, to apply the plaster and the other finishing material like stones and bricks, to set up the frame and the counter-frames to install doors, windows and french-windows.

[0005] Regarding the second category ("sandwich-type" cladding wall), the need to realize the vertical closures in the framework of a building with reinforced concrete bearing structure, which also have to provide thermal insulation and soundproofing, is accomplished through the supply and installation of metal box-like structure or wooden mullions, which have to be cut and install with stops, starting from the installation on the ground of the horizontal guide, then installing the vertical pillars and the upper horizontal guide, considering the exact positioning of the doors and window fixtures and the standard size of the closing panels. Moreover, it's necessary to install several closing panels, some best for thermal insulation and someone else best for vertical closures. The installation of the mullions and of the horizontal crosspieces, have to be made considering the verticality, the exact positioning of doors and windows and the size of the closing panels. The need to install the facilities' pipelines is accomplished modeling and cutting all the panels to have the space where to put these ducts. Therefore, also in this case, it's necessary to use several materials, interventions and skilled labors.

[0006] This second type of cladding wall (sandwich-type) can be realized also through the previous patent FR1577974A (Bot François), GB537187A (Coles George), GB555517A (Moss William), FR2455140A1 (Atelier ComposantsInd), FR905677A (Ploquin Maurice-Jean), GB683805A (Mario Carlos Lagos, Miguel Alfredo Curuchet). But all of them have limits that this patent application wants to overcome.

[0007] Particularly, the patent FR1577974A (Bot François) doesn't conceive the possibility to allow the transit of the facilities' pipelines from a modular element to the following one, nor to accommodate doors nor window fixtures. Furthermore, the resistance against transverse stresses is mediocre because the connections made with only one metal bar, not even gripped with resin seal, cause a pin effect that affects the solidity of the cladding walls. Moreover, there isn't any link between the building system of the cited patent and the bearing structure of the building, which involves that this building system can't resist well to seismic stresses and earthquakes. Another difference is the impossibility to accommodate anti-intruder components inside the elements nor any other installations without an intervention in the building site of skilled labour and without to require very big elements, which it's not even conceivable because they would be too much heavy, and very burdensome for the bearing structure.

[0008] The patent GB537187A (Coles George) seems very different to this patent application for the following reasons: first of all, it is not an alveolar element (not a hollow object) with exiguous connections, limited only to the bolting, realising a pin effect as the previous patent, so that it affects the solidity in case of seismic and transversal stresses. Therefore, this patent doesn't conceive the possibility to install any installation and not even any hole for the passing of the pipelines; it's not even possible to install more than one window fixture, also because it is not thick enough; the thickness can be implemented, otherwise it would be too much heavy because it has no holes to make it lighter. Moreover, it is unsuitable to provide thermal insulation because it has only one closing panel, only on one side, while the present patent application has at least two panels, but at the same time it's possible to add other ones, inside the thickness.

[0009] The patent GB555517A (Moss William), as the patent GB537187A (Coles George), doesn't conceive a hollow object, so it's the same difference as the previous one, also with reference to the relation solidity / weight of the cladding wall; moreover, it is conceived for only one closing panel and not allow a plurality of them. The cited patent is unsuitable to fill all the possible spaces between the pillars, because the elements have the same dimensional modularity, so that it's not possible to use this patent if the space isn't multiple of the elements.

[0010] The patent FR2455140A1 (Atelier Composants Ind) is different for several reasons: firstly, it hasn't a double gripping inside the thickness of the modular elements; moreover, it is not linked with the bearing structure of the building; besides, it doesn't allow the passing of the pipelines between the elements because the elements have only the holes predisposed for the bolting. Besides, the patent has a different "tongue and groove system", it has no resin seal or glue among the links; the element isn't a hollow object; it isn't conceived more than two elements; it isn't possible to install more than one window fixtures (window or shutters, not both at the same time).

[0011] The patent FR905677A (Ploquin Maurice-Jean) is still very different to this patent application, because that patent has no "tongue and groove system", nor holes in the thickness to accommodate the pipelines. The thickness must be exiguous, otherwise it would be too much heavy; it isn't conceived to install any installation nor window fixtures (only one of them maximum). It is conceived only one big element from the floor to the ceiling, which cause difficulties to be produced, stored, transported and installed. This system is unsuitable to resist to horizontal stresses in relation with its weight. Connections are made only with a linking pin inside the thickness of the element.

[0012] The patent GB683805A (Mario Carlos Lagos, Miguel Alfredo Curuchet) is different too, because the shape of the elements is totally different, there is no possibility to combine the elements to fill any possible space between the pillars, the reinforcing bars of the concrete is exiguous, and it has fragile components, especially during transportation and installation; it has no predispositions to install nor anti-intruder components inside the thickness, nor pipelines and ducts. It doesn't seem possible not even to cover the element with external or internal panels because, to be light, must be thin, so that it contains only one metal rebar. Although the element is predisposed to contain a window fixture, it isn't conceived to the installation of more than one (window or shuttering, not both of them as this patent application); finally, the connections between the elements are exiguous and not enough to resist to seisms.3. DISCLOSURE OF INVENTION

[0013] The invention is defined by the appended claim 1.

[0014] The appended claims 2 to 10 depend on claim 1 and are directed to preferred embodiments of the invention defined in claim 1.

[0015] This patent application concerns the kind of element, in its several shapes, sizes and materials and all the elements that derive from this, as well as the cladding walls built with those elements in their functionalities and applications, as well as the building system of the cladding walls and walls in general. Moreover, this patent application also concerns the use of these elements, or the ones that derive from them, to build fences, parapets, niches and all other uses.

[0016] The building system consists in the assembly of prefabricated modular elements, in reinforced concrete or in any other material, to realise a bearing "backbone" where to install the closing panels. The element with the "upside U letter shape" - here in after called element "Tipo A" - are positioned side by side to form a first horizontal line, on which are positioned side by side the second horizontal line, composed by the "H letter shape" - here in after called element "Tipo B" -. Therefore, the two lines form a framework on which it's possible to install the closing panel and the window fixtures (doors, windows, French windows and so on...).

[0017] The conception of a limited number of elements' typologies optimizes the factory's production, with low costs and a simplification of marketing activities; therefore, the elements are built in the industrial plant or in the factory with a serial production, even if it's possible an artisanal production too.

[0018] Although, despite the building system conceives the use of a limited number of elements' typologies and despite the elements have standard sizes not modifiable in the building site, it's possible to fill all the possible spaces between the pillars, also with the help of the special "Monocolonna" elements. In other words, assembling properly the elements, it's possible to obtain a huge number of possible applications, so that every time it's possible to choose the desired setting scheme. For this purpose, belong the basic elements "A", "A / 2", "B", "B / 2", "B2", "C", "C / 2", also special "Column" elements have been conceived. The latter, used sequentially, satisfies all the different possibilities needs, whatever is the distance between the pillars.

[0019] It is well understood that this building system conceives all possible size, which makes it suitable to every other real situation. The same concept is conceived also for the partition walls and any other possible need.

[0020] This building system shortens the processing time in the building site compared to other previous building system. Indeed, the bases of the elements could be fixed easily through metal rebars inserted in the holes and gripped with resin seals to the concrete (basement, foundations, curb, ...). It is important to notice that the connections are made with the help of a double line of metal rebars gripped with resin seals, which is different to the cited patents. In this building system, the elements are installed side by side and they are gripped with glue in some parts, located where there are the concrete reinforcements.

[0021] Concerning the installation side by side, the elements have on the external sides the "tongue and groove" system, finalized to give an interlocking effect between them. In some predisposed holes there are some metal rebars with resin seal to grip the post-installed shooting tools to the tooth. Concerning the installation one upon the other, every overlay between the lower and the upper element is conceived to insert four metal rebars, gripped with resin seal, into the predisposed holes at the basis of the elements.

[0022] Glue and adhesive paste are put between the contact points, to optimizes the resistance to the stresses.

[0023] Therefore, the elements form a geometric surface surrounded by the pillars, the intrados of the upper beam and the extrados of the lower one, which is the cladding wall's backbone. It's important to highlight that all the elements are in reinforced concrete, so that they form a surface with an its structural stiffness.

[0024] The same kind of connection is also conceived to the contact points between the external elements and the pillars and the beams, so that the framework is gripped to the building's bearing structure and has its own stiffness and it is also able to resist to stresses, both coplanar and perpendicular, like earthquake and wind.

[0025] The framework of cladding wall is also able to exchange the stresses with the building's bearing structure.

[0026] It's important to notice that everything will be subject to verification regarding the best quality of the materials and size to meet the requirements of every country's law.

[0027] In correspondence with the grooves, connections are made with improved adhesion bars shaped like a U-bolt and bonded with quick-setting cement mortar or resin.

[0028] Moreover, it's possible to realize the best solutions for any needs because it is very easy to install the elements side by side and link them.

[0029] This building system is advantageous because it shortens the processing time of interventions to do in building site compared to traditional building system, indeed the bases of the elements could be fixed easily through metal rebars inserted in the holes and gripped with resin seals to the concrete (basement, foundations, curb, ...).

[0030] Moreover, the many predisposed holes are conceived to the passing of pipelines and ducts, or they can be used for the ventilation, or closed with nozzles or vent, pvc caps or special panels.

[0031] Furthermore, the elements are suitable to accommodate window fixtures (doors, doorways, all size of windows, French windows and so on). More, with an enough thick element, it's possible to insert all the fixtures in the same element (e.g., window and shuttering inside the same element and pipelines passing between the linked elements). It's important to highlight that this building system is suitable also to realise ventilated cladding walls: it is enough to fix, after to have installed the first layer of thermal insulation material, some metal profiles (guides) to obtain a space (air chamber for ventilation) between the external thermal insulation panel and the external rigid closing finishing panel (e.g., fiber cement). It's possible to choose a huge variety of different finishing material.

[0032] They're conceived also the possibility to install anti-intruder components. They could be very important in the floors where is more likely to undergo vandal attacks: e.g., those anti-intruder components could be usefully adopted on the ground floor or next to passageways. Simple operative solutions are represented in the drawings; to be clear and concise, it is shown only one element, but the concept is extended to all the possible elements produced.4. VERSATILITY OF THE BUILDING SYSTEM CHOOSING ANOTHER MATERIAL (ZINC-PLATED STEEL ELEMENTS)

[0033] As an alternative to concrete which is the solution most fire resistant, the hollow elements are also conceived in zinc-plated steel which is the solution most light. The angular is fixed to the element with the help of self-drilling screws (or though the welding carried out in the establishment plant). The link to the ceiling is carried out through passing stops or similar other systems.

[0034] The zinc-plated steel elements have the same various holes conceived to the passing of the pipelines.

[0035] The elements can be used as room dividers between two flats or between rooms of the same flat.

[0036] As the case of vibrated concrete elements, also in this case it's possible to realise thinner or thicker elements, just considering the functionality's requirements in relation to vibration, deformability and so on. The results achieved from experimental tests have to meet the minimum allowed values.5. VERSATILITY OF THE BUILDING SYSTEM CHOOSING ANOTHER MATERIAL (ALUMINIUM AND WOOD)

[0037] As an alternative to concrete which is the solution most fire resistant, the hollow elements are also conceived in aluminium or wood which is the solution most light. The angular is fixed to the element with the help of self-drilling screws (or though the welding carried out in the establishment plant). The link to the ceiling is carried out through passing stops or similar other systems. Both aluminium and wood elements have the same various holes conceived to the passing of the pipelines.

[0038] The elements can be used as room dividers between two flats or between rooms of the same flat.

[0039] As the case of vibrated concrete elements, also in this case it's possible to realise thinner or thicker elements, just considering the functionality's requirements in relation to vibration, deformability and so on. The results achieved from experimental tests have to meet the minimum allowed values.6. TECHNICAL CHARACTERISTICS OF MATERIALS Proposed materials:

[0040] REINFORCED CONCRETE / PRESTRESSED CONCRETE ELEMENTS: ≥ cls c45 / 55; Steel for reinforcements: ≥ b450c, metal rebars; Resin seal to fix the metal rebars in the concrete blocks, strands and adhesive paste: as established by the applicable law; cement mortar: mixture of salt and quick-setting concrete; STEEL ELEMENTS: Box-shaped profiled galvanized cables: ≥ 2,5 mm minimum thickness; Steel: ≥ cl. 4; WOODEN ELEMENTS: laminated wood pre-treated with protective material, including anti-worm treatment; ALUMINIUM ELEMENTS: profiles in anodised aluminum with minimum thickness: ≥ 3 mm; All these elements and materials must have the qualities required by the applicable law and meet the required verifications.

[0041] More precisely, the technical characteristics of the materials used for the construction of each module, and of all the materials necessary for their installation, such as resins, bolts, adhesives, cement mortars, bars with improved adhesion, strands, etc. they may be diversified according to the needs of the single territory and the local market, but must always be suitable and meet the minimum requirements required by local regulations in terms of mechanical strength, deformability to stress, deformability for thermal excursions, durability, resistance to fire and safety in general.

[0042] Moreover, even maintaining the basic design criteria, it is be possible to envisage design adjustments in relation to the mechanical characteristics of the materials and the size of the elements (provided that the suitability for experimental verifications is met in terms of mechanical stresses that simulate seismic effects and also those due to wind, mechanical resistance and deformability).

[0043] These aspects, as all the verifications about the minimum requirements, are conceived to be extended to all versions of this system, including bollards, niches, anti-intrusive stiffeners, parapets, fencing railings, and so on.7. VERSATILITY OF THE BUILDING SYSTEM IN RELATION TO DIFFERENT USES

[0044] This building system is also conceived to be extended to other uses, specially through the zinc-plated steel elements with a lower thickness, for example to realise partition walls. The fixing to the ground and to the ceiling is carried out through metal brackets (angular), which have to be gripped to the elements with the help of self-drilling screws (or through the welding carried out in the factory). The fixing to the ceiling and in the intrados of the upper beam can be realised with the help of stops, chosen properly.

[0045] This building system involves important advantages, principally because it's very easy to assembly the elements and compose the framework of the partition wall and install doors and the other openings, so that the counter-frameworks for the fixtures are already prebuilt, inasmuch the element performs the function of counter-framework, therefore it's possible to avoid installing counter-frameworks.

[0046] Another advantage consists in the easy assembly of curvy partition walls; other advantage is the resistance in the two coplanar directions to the floor of the partition wall. The advantages can be wider choosing properly the modularity of the framework.

[0047] The hollow elements, specially the zinc-plated steel ones, aluminium ones and wooden ones, are suitable to be room dividers. Moreover, properly assembling, they can personalize the interior design and be part of the furniture. This is represented in the picture 174, where it's possible to see the elements performing the function of room dividers.

[0048] Besides, the elements can be used as pedestrian bollars (as you can see in the picture 173) or as parking bollards, both inside or outside.

[0049] Still, they can separate and personalize the corner of gardens or outside areas in general, they are suitable to provide shadows or as anti-introspective elements, and also in these cases can be integrated in the garden furniture. Finally, they are suitable as bearing structure for gazebos, pergolas, arbours, and so on. The connections are carried out as said before.

[0050] These elements can be used also on balconies, terraces, and so on: considering the easy assembly, they can perform as parapets. Inside the element, it is possible to insert several various materials, like Keller net, windows, ornamental concrete pots, and so on.

[0051] These materials can be installed just through bolting.

[0052] The elements are also suitable to realise fences at the properties' borders. The elements are suitable to be exposed (in this case, as all the other uses); in this case, especially if used outside, it's better to insert in the concrete mixture some water-repellent additives, quartz and oxides (colorants) to achieve likeable chromatic effects and avoiding painting the element (pictures 189-194).

[0053] This building system is suitable to realise niches, and especially in the residential building, to accommodate the utilities counters, or boilers, or washing machines.8. BRIEF DESCRIPTION OF DRAWINGS

[0054] The pictures 1-8 represent the building system: particularly, in the picture, it's possible to notice the installation of fiber-reinforced concrete (3), the thermal and acoustic insulation panel (rock wool or glass wool and so on) (2), the thermal and acoustic insulation material located inside the thickness of the elements, made up, for example, of polystyrene panels; in the picture 2, it's possible to notice the external panels (4), and the fixtures installed inside of each element; in the picture 3, it's possible to notice the materials installed on the bearing structure of this cladding wall building system, on the internal side, consisting - in this case - by OSB panels (5), fiber-reinforced concrete, light concrete panel, Fire panel, drywall, and finishing layer. In the picture 5, at the place of the light concrete panel or drywall or finishing layer (6) and (7) of picture 3, it's possible to notice the tiled panel (9), which is the best solution in kitchen and bathrooms. In all pictures 3, 4 and 5, it's possible to notice how to install, inside the thickness of the elements, the pipelines and the components of the installations, other than the thermal insulation and soundproofing material, as for example would be the rock wool, the glass wool, the polystyrene and so on (8); in the pictures 6, 7 and 8, it's possible to notice the application, on the external sides, of photovoltaic panels and / or any other kind of panel, eventually also realising ventilated wall.

[0058] These metal rebars or strands have the goal to link the elements each other; moreover, they perform the function to link the element to the ground and to the ceiling, at the intrados of the beam and laterally at the pillars, as represented in the following parts.

[0059] The picture 124 shows an axonometric cross section in which it's possible to see the details of the element A, A / 2 and Column element's bases, the position and the orientation of the holes to fix the element; the fixing is carried out putting resin seal on a double line of metal rebar or steel strands for each base.

[0062] The pictures 130 and 131 show two axonometric cross sections with the link and the solidification between two flanked elements' columns; some of the numerous holes is predisposed to insert the metal bars or strands to link the elements.

[0063] The pictures 132 and 133 show two axonometric cross sections with the link - the same - between the element's column and the pillar of the building's bearing structure. Also in this case, it's conceived to insert adhesive material between the element's column and the pillar of the bearing structure.

[0064] The pictures 134 and 135 represent the interlocking effect system, which is realised with the double line of metal bars toothed with resin seal and spreading the adhesive material, both under the bases of the elements and their upper side linked at the beam.

[0065] The pictures 136 and 137 highlight how the numerous holes are conceived to the passing of pipelines, ducts, and so on.

[0066] The picture 138 represents how it's possible to transport and to install each element, just with the help of a manual forklift.

[0067] The picture 139 highlights the possibility to install thermal insulation panels, without interruptions, overall external surface of the building, including the possibility to cover the surface of the pillars, before than install the closing panels (e.g., the fibre-reinforced concrete slab).

[0068] The pictures 140-147 show the insertion and the gripping, inside the thickness of the elements, of other concrete or metal barriers, it's possible to achieve always a better result, without an excessive increasing of costs and without make the product less aesthetic. Also, the times and the costs to assembly would not have excessive increasing of costs.

[0069] In the picture 140, inside the type element (10), is inserted the concrete slab with electrically welded mesh (11), which is gripped with pins (12) made of truncated cone reinforced concrete, fixed with resin seal.

[0070] The picture 141 shows, inside the type element, the insertion of a reinforced concrete slab (14), with electrically welded mesh, which has holes (13).

[0071] The picture 142, alternative to the previous one, shows the insertion of metal bars (15) inside the type element, which have to be fixed as in picture 143 with resin seal (16) in the predisposed holes.

[0072] The picture 144 shows, inside the type element (17), the insertion of a reinforced concrete slab (18), with electrically welded mesh, gripped with pins (19) made of truncated cone reinforced concrete, fixed with resin seal (20) at the slab's sides to the blocking. The picture 145 shows, inside the type element, the reinforced concrete slab (22) with holes (21), furnished of slots (23) at the sides, conceived to spread the adhesive material into, to the immediate blocking inside the element.

[0073] The picture 146 highlights the slots (24) of the slab (26), its holes (25) and the blocking pins (27). The picture 147 highlights the electrically welded mesh installed inside the concrete slab (28), or just the electrically welded mesh installed directly (29).

[0074] The pictures 148-154 show the fixing system consisting of metal angular elements with predisposed holes to be gripped to the ground and to the beam, which can be carried out with metal bars gripped to the concrete and using nuts and bolts (or stops) to insert in the concrete's hole; in the case of metal bars, the gripping to the concrete is carried out through resin seal. The pictures 155-166 represent the fixing system consisting, as the previous case, of metal angular elements with predisposed holes to be gripped to the ground and to the beam, which can be carried out with metal bars gripped to the concrete and using nuts and bolts (or stops) to insert in the concrete's hole; in the case of metal bars, the gripping to the concrete is carried out through resin seal.

[0076] The pictures 175-188 show what it's said before and the aesthetic view that the elements offer when they're installed on balconies and when they're used to personalize the external façade of a building.

[0077] The picture 205-207 show what it's said before. The connections are carried out with the help of metal bars toothed with resin seal into the predisposed holes between flanked elements; the connections between the elements and the pillars or the beams and the ceiling are carried out between metal bars, toothed with resin seal in the elements' holes. Particularly, the picture 205 highlights the lateral links along the pillar (42), the links between the elements (43), the upper side links at the beam's intrados (44), intermediate vertical links between the elements (45), the links through metal bars with protuberance shape (46), the lower links to the ground (47), the lateral links along the bearing's structure pillar (48).9. BEST MODE FOR CARRYING OUT THE INVENTION (EXAMPLE)

[0078] For demonstrative and exemplary purposes, it's hereby shown the case of a cladding wall which has to be built between two pillars of the bearing structure, with a net distance of 3,55 meters and height of 2,65 m. The simulation is carried out with basic types of elements (A, A / 2, B, B / 2, B2, C / 2, D, "A type left Column block", "B type left Column block", "A type right Column block", "B type right Column block", "angular A type column block", "angular B type column block".
