Description

DESCRIZIONE DESCRIPTION

TITOLO GOLDEN BEAM TRAVE LEGNEA CAVA TITLE GOLDEN BEAM BEAM WOOD QUARRY

A) Il campo della tecnica cui l’invenzione fa riferimento è quello della produzione di travi in legno per tetti e solai. A) The field of technique to which the invention refers is that of the production of wooden beams for roofs and floors.

B) Lo stato della tecnica precedente, per quanto a mia conoscenza, si limita a: B) The state of the previous technique, to the best of my knowledge, is limited to:

• travi in legno massello • solid wood beams

• travi in legno lamellare • glulam beams

• travi formate da due assi incollate fra di loro denominate “bilama” • beams formed by two boards glued together called "bilama"

C) Trattasi di una trave lignea per solai e tetti formata da quattro parti uguali di legno massello, disposte e incollate in modo da ottenere una sezione cava a rapporto aureo come da disegno allegato. C) This is a wooden beam for floors and roofs made up of four equal parts of solid wood, arranged and glued so as to obtain a hollow section with a golden ratio as per the attached drawing.

Le peculiarità innovative e salienti sono una maggiore portata e stabilità rispetto a qualsiasi altra trave lignea (ovviamente avente la stessa altezza), il minore peso, la minore quantità di legno impiegato, l’impossibilità a fessurarsi nel tempo. La colla usata può essere a discrezione del fabbricante, ad esempio la stessa delle travi lamellari. È consigliabile, alla fine, una levigatura delle quattro facce. The innovative and salient features are greater capacity and stability than any other wooden beam (obviously having the same height), the lower weight, the smaller amount of wood used, the inability to crack over time. The glue used can be at the manufacturer's discretion, for example the same as for lamellar beams. Finally, a smoothing of the four faces is recommended.

D) Il disegno rappresenta la sezione della trave in assonometria cavaliera. Da detto disegno si evince chiaramente la disposizione delle venature del legno delle quattro parti che, incollate tra di loro, andranno a formare la trave. D) The drawing represents the section of the beam in cavalier axonometry. This drawing clearly shows the arrangement of the wood grain of the four parts which, glued together, will form the beam.

E) Un modo di attuare l’invenzione è semplicemente quello di spalmare di colla le parti interessate, disporle come da disegno (eventualmente usando dei cavicchi o dei chiodi per mantenere la posizione) e serrarle con una pressa idraulica o altri mezzi meccanici per il tempo necessario alla presa del collante. E) One way to implement the invention is simply to smear the interested parts with glue, arrange them as per the drawing (possibly using pegs or nails to maintain the position) and tighten them with a hydraulic press or other mechanical means for the time necessary for the glue to set.

F) Come già detto l’utilizzo primario dell’invenzione è la costruzione di tetti e solai, o di qualsiasi altra struttura necessitante una travatura lignea. Anche un utilizzo in posizione verticale può dare ottimi risultati F) As already mentioned, the primary use of the invention is the construction of roofs and floors, or any other structure requiring wooden beams. Even use in a vertical position can give excellent results

RIVENDICAZIONI TITOLO GOLDEN BEAM TRAVE LIGNEA CAVA A) Le due tavole disposte orizzontalmente devono essere di taglio longitudinale tangenziale. B) Le due tavole disposte verticalmente devono assolutamente essere d taglio longitudinale radiale. C) Di dette assi è fondamentale mantenere la faccia che guarda verso il centro dell’albero dal quale sono state ricavate verso l’esterno della trave che andranno a formare. D) Le formule dimensionali sono le seguenti: • Altezza x 0.618 = Larghezza della trave • Larghezza x 1.618 = Altezza della trave • Spessore dell’asse o tavola = (Altezza-Larghezza) / 2 • Larghezza dell’asse o tavola = Larghezza della trave NB: Tutte e quattro le assi o tavole hanno la stessa dimensione. E) Intendo altresì rivendicare tutte le travi lignee cave aventi i rapporti di sezione esterna compresi tra 1 : 1 e 1 :4, ricordando che al calcolo degli spessori delle assi o tavole che andranno a costituire dette travi dovranno essere applicate formule diverse. Consiglio altri tre rapporti molto interessanti: 1 / 1,144 1 / 1,4142CLAIMS TITLE GOLDEN BEAM TRAVE LIGNEA CAVA A) The two boards arranged horizontally must have a longitudinal tangential cut. B) The two boards arranged vertically must absolutely have a longitudinal radial cut. C) Of these axes it is essential to keep the face facing the center of the shaft from which they have been obtained towards the outside of the beam they will form. D) The dimensional formulas are as follows: • Height x 0.618 = Width of the beam • Width x 1.618 = Height of the beam • Thickness of the axis or board = (Height-Width) / 2 • Width of the axis or board = Width of the beam NB: All four boards or boards have the same size. E) I also intend to claim all hollow wooden beams with external section ratios between 1: 1 and 1: 4, remembering that different formulas must be applied to the calculation of the thicknesses of the boards or boards that will make up said beams. I recommend three other very interesting reports: 1 / 1.144 1 / 1.4142
