Description
Forma oggetto del presente trovato un elemento di parete prefabbricato in calcestruzzo armato a coibenza termoacustica. The present invention relates to a prefabricated wall element in reinforced concrete with thermal-acoustic insulation.
Sono già noti elementi di parete di questo tipo, per costruzioni edili, aventi grandi dimensioni e vantaggiosamente un'altezza pari a quella di un piano di un edificio. Wall elements of this type are already known for building constructions, having large dimensions and advantageously a height equal to that of a floor of a building.
Un tipo di elemento di parete prefabbricato in calcestruzzo armato che si è bene affermato grazie alle sue ottime caratteristiche è descritto nel brevetto svizzero n. 616 194 concesso il 14.3.1980 della stessa richiedente. A type of prefabricated reinforced concrete wall element that has established itself well thanks to its excellent characteristics is described in Swiss patent no. 616 194 issued on 14.3.1980 by the same applicant.
Questo elemento noto a struttura monolitica di forma parallelepipeda con due facce opposte aventi un'area maggiore delle altre facce presenta una fila di fori passanti interspaziati paralleli ad un lato di dette facce maggiori, i quali fori servono, almeno in parte, da sedi a cassaforma per la gettata di calcestruzzo armato con ferri, in modo da formare veri e propri pilastri portanti all'interno dell'elemento, quando lo stesso viene messo in opera con i suoi fori passanti disposti verticalmente. This known element with a monolithic structure of parallelepiped shape with two opposite faces having an area greater than the other faces has a row of inter-spaced through holes parallel to one side of said larger faces, which holes serve, at least in part, as formwork seats for the casting of concrete reinforced with rods, so as to form real load-bearing pillars inside the element, when it is installed with its through holes arranged vertically.
L'elemento è armato con reti e tralicci elettrosaldati così da poter essere impiegato come elemento portante, anche a sbalzo. The element is reinforced with electro-welded meshes and pylons so that it can be used as a load-bearing element, even overhanging.
Esso riunisce in sé ottime caratteristiche di resistenza, massima maneggevolezza e leggerezza e grande praticità nella costruzione di edifici particolarmente anche in zone sismiche. It brings together excellent characteristics of resistance, maximum maneuverability and lightness and great practicality in the construction of buildings, especially in seismic areas.
Scopo del presente trovato è quello di perfezionare ulteriormente questo elemento noto, nel modo di aumentare la sua coibenza termoacustica, in modo da soddisfare meglio le esigenze dettate dalla necessità di risparmio di energia. The object of the present invention is to further improve this known element, in the manner of increasing its thermoacoustic insulation, so as to better meet the needs dictated by the need for energy saving.
In vista di questo scopo viene proposto un elemento di parete prefabbricato in calcestruzzo armato del tipo sopra indicato che è caratterizzato dal fatto che nel suo spessore, accanto a detta fila di fori passanti interspaziati, è prevista almeno una fila supplementare di fori passanti interspaziati paralleli ai fori della prima fila e sfalsati rispetto ad essi. In view of this purpose, a prefabricated reinforced concrete wall element of the type indicated above is proposed which is characterized in that in its thickness, at least one additional row of interspaced through holes parallel to the holes in the first row and offset from them.
I fori di questa fila supplementare aumentano di per sé la coibenza termoacustica dell'elemento, ma secondo una forma di esecuzione vantaggiosa esse possono essere riempite di materiale isolante, per ottenere un ulteriore aumento della coibenza termoacustica. The holes in this additional row increase in themselves the thermo-acoustic insulation of the element, but according to an advantageous embodiment they can be filled with insulating material, to obtain a further increase in thermo-acoustic insulation.
In una preferita forma di esecuzione l'elemento di parete secondo il trovato può presentare accanto alla prima fila di fori passanti interspaziati due file supplementari di fori, ma una incorrispondenza di ciascuna faccia maggiore dell'elemento. In questo caso i fori della fila supplementare in corrispondenza di una faccia maggiore possono essere chiusi almeno ad una estremità e costituire contenitori per sostanze fungenti da accumulatori di calore. In a preferred embodiment, the wall element according to the invention can have two additional rows of holes next to the first row of inter-spaced through holes, but one mismatch of each major face of the element. In this case, the holes of the additional row at a greater face can be closed at least at one end and constitute containers for substances acting as heat accumulators.
Le caratteristiche dell'elemento di parete secondo il trovato appariranno con maggiore chiarezza dalla seguente descrizione fatta con riferimento ai disegni allegati, in cui la fig. 1 mostra in sezione orizzontale un elemento di parete ed il modo di giunzione alle sue testate, The characteristics of the wall element according to the invention will appear more clearly from the following description made with reference to the attached drawings, in which fig. 1 shows a horizontal section of a wall element and the way of joining its heads,
la fig. 2 mostra in sezione secondo la linea II-II di fig. 1 la parte superiore dell'elemento, fig. 2 shows a section according to the line II-II of fig. 1 the upper part of the element,
la fig. 3 è una sezione secondo la linea III-III di fig. 1, e la fig. 4 è una vista dall'alto mostrante una possibilità di giunzione angolare. fig. 3 is a section along line III-III of fig. 1, and fig. 4 is a top view showing an angular joint possibility.
Come risulta chiaramente dai disegni, l'elemento di parete, indicato genericamente con 10, è costituito da un corpo monolitico in calcestruzzo armato di forma parallelepipeda che può essere ottenuto vantaggiosamente per gettata di calcestruzzo in forme verticali previa disposizione dell'armatura di ferro. Vantaggiosamente l'elemento 10 ha un'altezza di un piano con due facce opposte aventi un'area maggiore delle altre facce. L'elemento 10 illustrato presenta tre file parallele di fori passanti interspaziati paralleli ad un lato delle facce maggiori che quando l'elemento è in opera possono essere quindi disposti verticalmente. As is clear from the drawings, the wall element, generally indicated by 10, consists of a monolithic reinforced concrete body of parallelepiped shape which can be advantageously obtained by pouring concrete in vertical shapes after having provided the iron reinforcement. Advantageously, the element 10 has a height of a plane with two opposite faces having an area greater than the other faces. The element 10 illustrated has three parallel rows of inter-spaced through holes parallel to one side of the major faces which, when the element is in operation, can therefore be arranged vertically.
Una prima fila di fori 11 che nel caso illustrato si trova al centro dell'elemento 10 è destinata, in parte, a costituire sedi a cassaforma per la gettata di calcestruzzo 12 armato con ferri 13, così da formare pilastri portanti all'interno dell'elemento. Il numero di questi pilastri gettati entro un elemento di parete e la quantità di ferro vengono determinati in sede di calcolo in base alle sollecitazioni a cui la struttura dovrà resistere. Questi pilastri gettati possono servire anche alla realizzazione di connessioni stabili fra elementi, eventualmente previa asportazione di parti di pareti degli elementi, in modo da avere un'unica cassaforma per il getto di pilastri che fungono da mezzo di collegamento fra gli elementi. A first row of holes 11 which in the illustrated case is at the center of the element 10 is intended, in part, to form formwork seats for the pouring of concrete 12 reinforced with rods 13, so as to form load-bearing pillars inside the element. The number of these pillars thrown into a wall element and the quantity of iron are determined when calculating based on the stresses that the structure will have to resist. These thrown pillars can also serve to create stable connections between elements, possibly after removing parts of the walls of the elements, so as to have a single formwork for the casting of pillars which act as a means of connection between the elements.
Accanto ala fila centrale di fori 11 l'elemento di parete 10 illustrato presenta due file supplementari di fori 14 e rispettivamente 15, in corrispondenza delle due facce maggiori opposte dell'elemento stesso, sfalsati rispetto ai fori 11 della prima fila. In opera, l'elemento 10 viene disposto in modo tale che la fila di fori 14 si trovi in corrispondenza della faccia dell'elemento rivolta verso l'esterno, mentre la fila di fori 15 si trovi in corrispondenza della faccia interna. Next to the central row of holes 11 the wall element 10 illustrated has two additional rows of holes 14 and 15 respectively, in correspondence with the two opposite major faces of the element itself, staggered with respect to the holes 11 of the first row. On site, the element 10 is arranged in such a way that the row of holes 14 is in correspondence with the face of the element facing outwards, while the row of holes 15 is in correspondence with the internal face.
È evidente che queste file supplementari di fori aumentano di per sé la coibenza termoacustica dell'elemento di parete 10. It is evident that these additional rows of holes increase in themselves the thermal-acoustic insulation of the wall element 10.
È possibile prevedere anche una sola fila supplementare di fori, in qual caso l'elemento viene disposto in opera preferibilmente in modo che questa fila supplementare di fori si trovi in corrispondenza della faccia esterna. It is also possible to provide a single additional row of holes, in which case the element is preferably arranged on site so that this additional row of holes is in correspondence with the external face.
I fori 14 e 15 possono avere una sezione minore dei fori 11: nel caso illustrato questi ultimi hanno una sezione sostanzialmente quadrata, mentre i fori 14 e 15 hanno sezione rettangolare con i lati maggiori disposti in piani paralleli alle facce maggiori dell'elemento 10. The holes 14 and 15 can have a smaller section than the holes 11: in the illustrated case the latter have a substantially square section, while the holes 14 and 15 have a rectangular section with the longer sides arranged in planes parallel to the major faces of the element 10.

Per aumentare il coefficiente di coibenza termoacustica dell'elemento 10, i fori 14 della fila in corrispondenza della faccia destinata ad essere rivolta verso l'esterno vengono preferibilmente riempiti di materiale isolante, come per esempio poliuretano espanso, indicato con 16. To increase the thermo-acoustic insulation coefficient of the element 10, the holes 14 of the row at the face intended to face outwards are preferably filled with insulating material, such as for example expanded polyurethane, indicated with 16.
I fori 15 della fila in corrispondenza della faccia destinata ad essere rivolta verso l'interno possono essere chiusi almeno alla loro base, come visibile in fig. 3, in modo da formare dei contenitori che con l'elemento in opera sono verticali. In tali contenitori può essere introdotta una adatta soluzione, per esempio paraffina, atta a fungere da accumulatore di calore. Questa soluzione può essere riscaldata da una serpentina (non illustrata) facente capo per esempio a pannelli solari ed immersa nella soluzione stessa. In tal modo la soluzione può venire riscaldata di giorno per cedere il calore durante le ore notturne: l'elemento di parete, dalla parte rivolta verso l'interno, può assumere così funzione di piastra radiante. The holes 15 of the row at the face intended to face inwards can be closed at least at their base, as shown in fig. 3, so as to form containers which are vertical with the element in place. A suitable solution, for example paraffin, suitable to act as a heat accumulator, can be introduced into these containers. This solution can be heated by a coil (not shown) headed for example by solar panels and immersed in the solution itself. In this way the solution can be heated during the day to release the heat during the night: the wall element, from the side facing inwards, can thus take on the function of a radiant plate.
Come è stato detto, l'elemento di parete 10 in calcestruzzo è armato in ferro, e dai disegni si vede come l'armatura può essere costituita da reti metalliche 17 e tralicci 18 elettrosaldati. La quantità di ferro impiegato è calcolata in base alle sollecitazioni a cui la struttura dovrà resistere, qualora impiegata come elemento portante, sia in sede di prefabbricazione che di esercizio. As has been said, the concrete wall element 10 is reinforced with iron, and from the drawings it can be seen how the reinforcement can be made up of wire mesh 17 and electrically welded pylons 18. The quantity of iron used is calculated on the basis of the stresses that the structure will have to withstand, if used as a load-bearing element, both during prefabrication and during operation.
Alla sua sommità l'elemento 10 presenta le sue due pa-5 reti contrapposte in cui sono ricavate le file di fori 14 e 15 sporgenti verso l'alto rispetto alla parte centrale dell'elemento in cui è ricavata la fila di fori 11: si crea così in alto uno spazio di contenimento 19 (vedi particolarmente figg. 2 e 3) atto a contenere il getto di correa che costituisce una trave io di collegamento che dà alla struttura complessiva tutte le caratteristiche di una struttura intelaiata. At its top, the element 10 has its two opposite sides in which the rows of holes 14 and 15 protrude upwards with respect to the central part of the element in which the row of holes 11 is obtained are obtained: thus creates at the top a containment space 19 (see particularly figs. 2 and 3) suitable for containing the jet of correa which constitutes a connecting beam which gives the overall structure all the characteristics of a framed structure.
Lo schema strutturale dell'insieme risponde quindi alla esigenza di realizzare una solidarizzazione effettiva fra i vari elementi, stabilizzata da particolari collegamenti in grado 15 di resistere ad eventi accidentali prevedibili entro certi limititi. Esso si presta quindi particolarmente anche per costruzioni in zone sismiche. The structural scheme of the whole therefore responds to the need to achieve effective solidarity between the various elements, stabilized by particular connections capable of withstanding foreseeable accidental events within certain limits. It is therefore particularly suitable also for constructions in seismic areas.
La fig. 1 del disegno illustra poi una possibilità di reciproco accoppiamento di più elementi 10 messi l'uno in pro-20 secuzione dell'altro, mentre in fig. 4 è mostrato un possibile giunto ad angolo tra due elementi di parete 10. Questi accoppiamenti sono illustrati a puro titolo indicativo. Fig. 1 of the drawing then illustrates a possibility of mutual coupling of several elements 10 placed one in pro-20 secution of the other, while in fig. 4 shows a possible corner joint between two wall elements 10. These couplings are illustrated by way of example only.
