Description

Descrizione del trovato avente per titolo: TRAVE PER SOSTEGNI E RELATIVO PROCEDIMENTO DI REALIZZAZIONE". Description of the invention having the title: BEAM FOR SUPPORTS AND RELATED CONSTRUCTION PROCEDURE ".

CAMPO DI APPLICAZIONE FIELD OF APPLICATION

Formano oggetto del presente trovato una trave per sostegni nonché il procedimento per realizzarla. The present invention relates to a beam for supports as well as the method for making it.

STATO DELLA TECNICA STATE OF THE TECHNIQUE

Sono note le travi costituite da profilati tubolari di sezione poligonale ottenute partendo da lamiera e saldando in continuo e di testa i due lembi di chiusura del profilato. Beams consisting of tubular profiles with a polygonal section are known, obtained starting from sheet metal and by butt-welding the two closing edges of the profile.

Nel caso di magazzini, queste travi presentano, in relazione allo spessore della lamiera di partenza ed in relazione alle dimensioni dei due lati del rettangolo o del quadrato, uno spessore superiore al necessario sui lati lunghi che, in opera, risultano posizionati verticalmente ed uno spessore inferiore al necessario sui lati corti che, di fatto, risultano essere posizionati, in opera, orizzontalmente. In the case of warehouses, these beams have, in relation to the thickness of the starting sheet and in relation to the dimensions of the two sides of the rectangle or square, a thickness greater than necessary on the long sides which, in operation, are positioned vertically and a thickness lower than necessary on the short sides which, in fact, are positioned horizontally on site.

Anche nel caso di profili scatolari quadrati si pone di fatto lo stesso problema. Even in the case of square box-shaped profiles the same problem actually arises.

Infatti, in fase di magazzinaggio, in cui la trave deve solo sostenere un carico statico, i profili tubolari normali, a parità di dimensioni, presentano un eccesso di resistenza; mentre in fase di applicazione del carico, alle volte risultano insufficienti . In fact, in the storage phase, in which the beam only has to support a static load, the normal tubular profiles, with the same dimensions, have an excess of resistance; while in the load application phase, they are sometimes insufficient.

Il presente trovato tende a risolvere i succitati problemi con una nuova trave ottenuta con un procedimento nuovo. The present invention tends to solve the aforementioned problems with a new beam obtained with a new process.

ESPOSIZIONE DEL TROVATO EXPOSURE OF THE FOUND

Secondo il trovato, l'idea di soluzione è espressa nelle rispettive rivendicazioni principali di prodotto e di procedimento. According to the invention, the idea of a solution is expressed in the respective main product and process claims.

Secondo il trovato, un profilato tubolare di sezione quadrata o rettangolare, vantaggiosamente rettangolare, viene previsto partendo da una lamiera sottile . According to the invention, a tubular profile having a square or rectangular section, advantageously rectangular, is provided starting from a thin sheet.

La lamiera presenta uno spessore che varia da 1,0 mm a 2,5 mm per ottenere una sezione che varia da 40 a 60 mm per il lato corto e da 80 a 150 mm per il lato lungo. Queste dimensioni dipendono dal carico unitario che la trave deve sostenere. The sheet metal has a thickness ranging from 1.0 mm to 2.5 mm to obtain a section ranging from 40 to 60 mm for the short side and from 80 to 150 mm for the long side. These dimensions depend on the unit load that the beam has to support.

Secondo il trovato, almeno il lato corto che viene posizionato superiormente è costituito da una sequenza voluta di pieghe continue di altezza voluta. According to the invention, at least the short side which is positioned above is constituted by a desired sequence of continuous folds of desired height.

Detta altezza varia da 6 mm a 15 mm. Said height varies from 6 mm to 15 mm.

Dette pieghe vengono realizzate in sequenza con un numero idoneo di passaggi di profilatura. Said folds are made in sequence with a suitable number of profiling passages.

Secondo il trovato le pieghe ottenute sono tali da tenere la lamiera che sale e quella che scende, e così via alternativamente, a stretto contatto sì da costituire un corpo unico. According to the invention, the folds obtained are such as to keep the sheet metal that rises and that which descends, and so on alternately, in close contact so as to constitute a single body.

Secondo una variante del trovato, le pieghe sono collegate tra loro attraverso una serie di passaggi di profilazione. Negli stessi passaggi si ottiene la chiusura dei lembi mediante grafiettatura. According to a variant of the invention, the folds are connected to each other through a series of profiling passages. In the same steps, the flaps are closed by means of scratching.

Una volta ottenuto il profilo, questo viene successivamente profilato attraverso rulli di calibrazione diventando corpo unico, il tutto prodotto in linea da un nastro di lamiera. Once the profile has been obtained, it is subsequently profiled through calibration rollers becoming a single body, all produced in line from a sheet metal strip.

Secondo un'ulteriore variante, le pieghe sono collegate tra loro da un punto o da una linea, di saldatura, il tutto realizzato di tanto in tanto. Secondo un'ulteriore variante, la tenuta laterale delle pieghe è ottenuta con un elemento a cavaliere ad "U", posto di tanto in tanto, o in continuo, per lunghezze sostanziali, che s'inserisce con le sue gambe terminali tra le due pieghe laterali. According to a further variant, the folds are connected to each other by a welding point or line, all made from time to time. According to a further variant, the lateral sealing of the folds is obtained with a "U" -shaped rider element, placed from time to time, or continuously, for substantial lengths, which is inserted with its terminal legs between the two folds side.

Secondo un'ulteriore variante, la zona pieghettata è solidarizzata con un perno passante posto di tanto in tanto e saldato alle estremità. According to a further variant, the pleated area is integral with a through pin placed from time to time and welded at the ends.

Secondo un'ulteriore variante, entrambi i lati corti sono ottenuti nello stesso modo e cioè con le pieghe. According to a further variant, both short sides are obtained in the same way, that is with the folds.

Secondo un'ulteriore variante, sui lati lunghi è presente almeno una modificazione della linearità per migliorare la robustezza strutturale. Tale modificazione della linearità può essere a "U" a "V" o a "C", o secondo altra sagoma, essendo indifferente la forma geometrica. According to a further variant, on the long sides there is at least one modification of the linearity to improve the structural strength. This modification of the linearity can be "U" to "V" or "C", or according to another shape, the geometric shape being indifferent.

Secondo il trovato, la trave viene ottenuta procedendo da un nastro di larghezza voluta ed inferendo, partendo dalla piega centrale, le pieghe che costituiscono almeno un lato corto. According to the invention, the beam is obtained by proceeding from a strip of desired width and inferring, starting from the central fold, the folds which constitute at least one short side.

Secondo il trovato le altre pieghe, la solidarizzazione a secco ed il bloccaggio dei lembi laterali avviene con una sequenza progressiva potendosi concretizzare due fasi anche contemporaneamente. According to the invention, the other folds, the dry solidarization and the locking of the side flaps take place in a progressive sequence, since two phases can also be carried out simultaneously.
