TRAVE COMPOSITA PER IL SOSTEGNO DI CASSERATURE PER LA REALIZZAZIONE DI TRAVI RIBASSATE IN CALCESTRUZZO ASSOCIATE A SOLAI COMPOSED BEAM FOR THE SUPPORT OF FORMWORKS FOR THE CONSTRUCTION OF LOWERED CONCRETE BEAMS ASSOCIATED WITH FLOORS
DESCRIZIONE DESCRIPTION
Forma oggetto del presente trovato una trave composita per il sostegno di casserature per la realizzazione di travi ribassate in calcestruzzo. La trave ribassata à ̈ un elemento strutturale di un solaio e viene per lo più impiegata a fini antisismici. The present invention relates to a composite beam for supporting formworks for making lowered concrete beams. The lowered beam is a structural element of a floor and is mostly used for anti-seismic purposes.
La trave, realizzata in calcestruzzo armato, ha la caratteristica di sporgere dalla parte inferiore del solaio. The beam, made of reinforced concrete, has the characteristic of protruding from the lower part of the floor.
La realizzazione di questo tipo di trave risulta essere complessa nella realizzazione in quanto l'armo à ̈ sempre realizzato in modo, per così dire tradizionale, con tavole e cunei di legno e quindi la buona riuscita à ̈ legata all'abilità del carpentiere. The realization of this type of beam turns out to be complex in the realization as the frame is always made in a traditional way, with wooden boards and wedges and therefore the success is linked to the skill of the carpenter.
Esistono anche casserature che vengono realizzate con squadre di acciaio regolabili o fisse che comportano comunque operazioni complesse tempi lunghi e costi notevoli. There are also formworks that are made with adjustable or fixed steel squares which in any case involve complex operations, long times and considerable costs.
Con questi sistemi vi à ̈ altresì la difficoltà di impiegarli in sistemi che prevedono il recupero anticipato dei pannelli contigui alla trave. With these systems there is also the difficulty of using them in systems that provide for the early recovery of the panels adjacent to the beam.
Scopo principale del presente trovato à ̈ mettere a punto una trave composita che consenta una veloce e precisa realizzazione di un cassero per il getto di una trave ribassata. The main purpose of the present invention is to provide a composite beam which allows a fast and precise realization of a formwork for casting a lowered beam.
Conseguente primario scopo à ̈ di realizzare una trave composita che presenti un'alta resistenza ai carichi. A consequent primary purpose is to provide a composite beam which has a high resistance to loads.
Ulteriore scopo à ̈ quello di mettere a punto una trave composita che sia facilmente associabile ai sistemi conosciuti per la preparazione di strutture per il getto di solai in cemento armato. Non ultimo scopo à ̈ quello di mettere a punto una trave composita di costo contenuto, facilmente riutilizzabile e standardizzata. A further aim is to develop a composite beam that can be easily associated with known systems for preparing structures for casting reinforced concrete floors. Not least object is to provide a composite beam of low cost, easily reusable and standardized.
Questi ed altri scopi ancora che più chiaramente appariranno in seguito sono raggiunti da una trave composita per il sostegno di casserature per la realizzazione di travi ribassate in calcestruzzo associata ad un solaio, caratterizzata dal fatto di comprendere un profilo estruso in alluminio, con sezione simmetrica rispetto ai piani orizzontali e verticali relativamente alla messa in opera, dotato di vani aperti per l'inserimento di controsagomati profili di legno interessanti solo parzialmente la sua lunghezza e di zone terminali asolate per l'inserimento di tiranti di sostegno e regolazione associabili all'armatura per il getto di un solaio. These and other purposes that will appear more clearly later are achieved by a composite beam for supporting formwork for the construction of lowered concrete beams associated with a floor, characterized by the fact that it comprises an extruded aluminum profile, with a symmetrical section with respect to to the horizontal and vertical planes relative to the installation, equipped with open compartments for the insertion of counter-shaped wooden profiles which only partially affect its length and with slotted end areas for the insertion of support and adjustment tie-rods that can be associated with the reinforcement for the casting of an attic.
Ulteriori caratteristiche e vantaggi risulteranno maggiormente dalla dettagliata descrizione della trave secondo il trovato tale descrizione venendo data con l'ausilio delle allegate figure contenute nelle tavole di disegni in cui: Further characteristics and advantages will become clearer from the detailed description of the beam according to the invention, this description being given with the aid of the attached figures contained in the tables of drawings in which:

- la figura 8 mostra una vista superiore della trave secondo il trovato. figure 8 shows a top view of the beam according to the invention.
Con riferimento alle figure citate nella figura 1 à ̈ illustrato un sistema globale di getto di un solaio di cui due sue parti sono indicate con i numeri 11 e 12 fra le quali à ̈ interposta una trave ribassata indicata con 13. With reference to the figures cited in figure 1, a global casting system of a floor is shown, two of its parts being indicated with the numbers 11 and 12 between which a lowered beam is interposed indicated with 13.
Il sistema di sostegno del solaio à ̈ di tipo tradizionale costituito da puntelli in alluminio 14 dotati di teste cadenti 15 supportanti delle travi con profilo dentato 16 che a loro volta portano un pannello superiore in alluminio 17 sul quale verrà eseguito il getto del solaio. The floor support system is of the traditional type consisting of aluminum props 14 equipped with drooping heads 15 supporting beams with toothed profile 16 which in turn carry an upper aluminum panel 17 on which the floor casting will be performed.
Il sistema prevede ancora una trave composita 18 che à ̈ l'oggetto del brevetto che unitamente ad altre travi dello stesso tipo disposte parallelamente consente il posizionamento di murali in legno 19 à ̈ sostenuta una casseratura 20 che risulta ribassata rispetto alla base del solaio consentendo di ottenere uno spazio longitudinale ove verrà creata la trave ribassata 13. The system still provides a composite beam 18 which is the subject of the patent which together with other beams of the same type arranged parallel allows the positioning of wooden murals 19 a formwork 20 is supported which is lowered with respect to the base of the floor allowing to obtain a longitudinal space where the lowered beam 13 will be created.
In figura 2 si vede con una vista assonometrica l'intero sistema sia di base d'appoggio per il getto del solaio sia di casseratura. Figure 2 shows an axonometric view of the entire system of both the support base for the casting of the floor and the formwork.
Nella figura 3 si vede la stessa situazione ma vista da sotto in modo da evidenziare la disposizione sia dei puntelli 14 che delle travi composite 18 ed ancora dei murali 19 che consentono di realizzare la casseratura 20 per la trave ribassata 13. Figure 3 shows the same situation but seen from below in order to highlight the arrangement of both the props 14 and the composite beams 18 and again of the murals 19 which allow the formwork 20 to be made for the lowered beam 13.
La figura 4 mostra la trave composita 18 e mostra ancora dei tiranti 21 che sono superiormente associati alla trave 17 e che presentano una filettatura a passo allungato che consente di posizionare la trave 18 in modo preciso utilizzando delle placche a dado superiori 22a e doppie inferiori 22b e 22c così da bloccare in sicurezza la trave composita 18 sopra la quale verranno posizionati i murali 19 e la casseratura 20 per predisporre il getto della trave ribassata. Figure 4 shows the composite beam 18 and again shows some tie rods 21 which are associated at the top with the beam 17 and which have an elongated pitch thread that allows the beam 18 to be positioned precisely using upper 22a and double lower 22b nut plates. and 22c so as to safely lock the composite beam 18 above which the murals 19 and the formwork 20 will be positioned to prepare the casting of the lowered beam.
La trave 18 come si vede nella figura 6 Ã ̈ realizzata con un estruso in alluminio simmetrico rispetto ad un piano verticale e ad un piano orizzontale indicato con 18a dove vengono creati due vani aperti 23 e 24 dove vengono inseriti dei controsagomati profili in legno 25 e 26. The beam 18 as seen in figure 6 is made with an extruded aluminum symmetrical with respect to a vertical plane and a horizontal plane indicated with 18a where two open compartments 23 and 24 are created where counter-shaped wooden profiles 25 are inserted and 26.
I due vani sono separati da un setto di irrobustimento 27 che rende ulteriormente stabile la struttura. The two compartments are separated by a strengthening partition 27 which makes the structure even more stable.
I profili in legno 25 e 26 risultano accessibili con facce 28a e 28b ove à ̈ possibile la chiodatura dei murali oppure il posizionamento di chiodi laterali ai murali che ne consentono un posizionamento stabile ed esatto. The wooden profiles 25 and 26 are accessible with faces 28a and 28b where it is possible to nail the murals or the positioning of lateral nails to the murals that allow a stable and exact positioning.
In figura 7 à ̈ mostrata una variante della sezione della trave di cui alla figura 6 dove i vani per l'inserimento dei profili in legno ora indicati con 29 e 30 sono di dimensioni ridotta mentre à ̈ creato uno spazio intermedio 31 a mezzo di due setti 27a e 27b nel profilato dell'estruso che ne consente un ulteriore maggiore stabilità dimensionale. Figure 7 shows a variant of the section of the beam in figure 6 where the compartments for the insertion of the wooden profiles now indicated with 29 and 30 are of reduced dimensions while an intermediate space 31 is created by means of two partitions 27a and 27b in the profile of the extrusion which allows a further greater dimensional stability.
I profili in legno del tipo 25, 26, 29 e 30, come si vede in figura 8 ove sono indicati semplicemente con il numero 32 non interessano l'intera lunghezza della trave ancora indicata con 18 ma lasciano aperte due zone terminali asolate 33 e 34 per consentire il passaggio dei tiranti 21 ed il loro corretto posizionamento ed adattamento. Quando le travi sono poste in opera sono, se necessario, ulteriormente sorrette come si vede nelle figure 1, 2 e 3 da ulteriori puntelli indicati con 35 che consentono di contribuire a portare il carico della trave ribassata, se risulta molto pesante. The wooden profiles of the type 25, 26, 29 and 30, as seen in figure 8 where they are simply indicated with the number 32, do not involve the entire length of the beam still indicated with 18 but leave two slotted end areas 33 and 34 open. to allow the passage of the tie rods 21 and their correct positioning and adaptation. When the beams are installed they are, if necessary, further supported as seen in figures 1, 2 and 3 by further props indicated with 35 which allow to help carry the load of the lowered beam, if it is very heavy.
Con una trave composita di questo tipo si ottengono numerosi evidenti vantaggi che sono in particolare quelli legati alla facile preparazione di una casseratura per la realizzazione di una trave ribassata. Numerous obvious advantages are obtained with a composite beam of this type, which are in particular those linked to the easy preparation of a formwork for making a lowered beam.
Con una struttura di questo tipo à ̈ possibile mediante l'uso dei tiranti a barra filettata 21 un facile posizionamento della casseratura sostenendo il tutto alle travi 16 supportate dai puntelli 14. A getto eseguito à ̈ successivamente possibile disarmare anticipatamente l'intero getto del solaio lasciando in particolare i puntelli 35 che sostengono le travi composite che a loro volta sostengono la trave ribassata che ha un tempo di maturazione molto più lungo del tempo di maturazione del solaio. With a structure of this type it is possible through the use of threaded rod tie rods 21 an easy positioning of the formwork supporting everything to the beams 16 supported by the props 14. Once the casting has been carried out, it is subsequently possible to disarm the entire casting of the floor in advance. leaving in particular the props 35 which support the composite beams which in turn support the lowered beam which has a much longer curing time than the curing time of the floor.
