Definitions
- the present invention relates to a covering device for buildings in general and for industrial and/or commercial buildings in particular.
- Prefabricated elements are currently used in the construction of industrial and/or commercial buildings in order to industrialize the construction of such buildings. Said prefabricated elements, and most of all the roofing beams with the related pillar-connecting supporting beams, have undergone great development in the recent past in order to decrease the amount of on-site work, improve the aesthetic appearance of said buildings and at the same time increase the weatherability and insulation of said buildings.
- Said roofing beams are in fact too heavy, i.e. they require too much reinforced concrete for their manufacture; on one hand, this entails an excessive load on the pillar-connecting supporting beams, which limits the distance between the pillars to a maximum of 12 meters, and on the other hand constitutes a considerable hindrance to the transportation of said roofing beams on road vehicles.
- roofing beams having spans in the range of 20-25 meters, there were in fact limited possibilities of transportation throughout the territory due to the excessive weight of each roofing beam.
- the assembly system which entailed a pillar-connecting beam with an H-shaped cross-section with supporting ledges for the ends of the roofing beam, is particularly sensitive, during the assembly of said roofing beams, to impacts due to the oscillations of said roofing beams which thus damage said pillar-connecting beam.
- roofing beams required, during their manufacture, the insertion of metallic elements in their wings in order to fix, during the assembly of the covering, roofing panels connecting spaced roofing beams arranged side by side. Both the insertion of the metallic elements and the complicated assembly of said roofing panels entailed an increase in costs which affected the marketability of the product, i.e. of the prefabricated roof.
- the aim of the present invention is to eliminate or substantially reduce the problems described above in known types of roofing beams by providing a covering device for buildings in general and for industrial and/or commercial buildings in particular which substantially reduces the weight of each roofing beam, thus increasing the transportability of said roofing beams for an equal span or length.
- an object of the present invention is to provide a covering device which eliminates any possibility of damage to the pillar-connecting beam during on-site assembly.
- Another object of the present invention is to provide a covering device which eliminates the insertion of metallic elements for the fitting of the roofing panels.
- Not least object of the present invention is to provide a covering device which is relatively easy to manufacture and at competitive costs.
- a covering device for buildings in general and for industrial and/or commercial buildings in particular according to the invention characterized in that it comprises side beams which can be coupled to supporting pillars, said side beams defining a ledge for supporting roofing beams which have a constant width with a central single ridge, a concave shape in a cross-section taken transversely to the extrados and a straight intrados and a flat extrados in a longitudinal cross-section taken along the median plane, with longitudinal edges provided with reinforcement ridges, said roofing beams being spaced and arranged side by side and engaging curved roofing panels constituted by composite plate-like elements arranged side by side, said roofing beams having, on their extrados, an insulating layer and a waterproofing layer, said layers being factory-applied and being laterally delimited by said lateral ridges of said edges and defining, on the extrados, inclined surfaces whose slope varies from a median portion of said roofing beam
- a covering device for buildings in general and for industrial and/or commercial buildings in particular comprises side beams 1 which can be coupled to supporting pillars 2.
- the side beams 1 define a ledge 3 for supporting roofing beams 4.
- Each roofing beam 4 has a constant width with a single central ridge 5 and has, in a cross-section taken transversely to the extrados, as more clearly shown in figures 4 and 11, a concave shape defined by two wings 6 and 7 which extend from the single ridge 5 and which define and delimit, between them, a platform 8. It is furthermore possible to provide a flat arch 8a which joins the wings 6 and 7, delimiting a closed space 8b, thus obtaining greater inertia of the roofing beam.
- the roofing beam 5 furthermore has, in a longitudinal cross-section taken along the median plane, a preferably straight intrados and a flat extrados, and the longitudinal wings or edges 6 and 7 have respective reinforcement ridges 9 and 10 which rise from the wings themselves.
- roofing beams as more clearly shown in figure 1, are spaced and arranged side by side, and roofing panels 11 engage on the ridges 9 and 10 of the wings 6 and 7.
- Each roofing panel 11 has a curved shape and is constituted by composite plate-like elements.
- Each roofing beam 4 has, on its extrados, i.e. on the platform 8 and on the wings 6 and 7, an insulating layer 12 and a waterproofing layer 13 which are both factory-applied; a polystyrene block 8c can furthermore be provided in the space 8b.
- the insulating layer 12 and the waterproofing layer 13 are laterally delimited by the lateral ridges 9 and 10 of the wings 6 and 7 and define, on the extrados, inclined surfaces whose slope varies from a median portion of each roofing beam 4 toward its longitudinal ends or heads.
- Each side beam 1 has, in a transverse cross-section and as shown in figure 10, a substantially omega-like shape with a lower groove 14 for coupling to a ridge 15 of a respective supporting pillar 1.
- the wings 6 and 7 have, in a cross-section taken transversely to the extrados of the respective roofing beam 4, a radius of curvature which is constant along the entire longitudinal extension, thus simplifying manufacture, as more clearly explained hereinafter.
- Each roofing panel 11 can be fixed to the respective reinforcement ridge 9 or 10 by virtue of fixing means, such as nails 16, screws and the like, advantageously simplifying the assembly operations, as will become apparent hereinafter.
- Each roofing beam 4 has, at its ends, lightened heads 17 which have lower surfaces 18 for resting on the respective ledges 3 of the side beams 1.
- the lower resting surfaces 18 are constituted, as more clearly illustrated in figures 3 and 5, by expansions of the single ridge 5.
- Each head 17 has a sloping shape, as illustrated in figures 2, 9 and 10, in order to improve meteoric water drainage.
- the sloping shape of the heads 17 defines an acute angle together with the lower surface 18.
- Each lightened head 17 has, in a median portion, recesses 50 of metallic devices used to vertically store and transport stacked roofing beams and has, along its lateral edges, accommodation seats 19 for ridges 20, shaped complementarily with respect to the accommodation seats 19, which extend from longitudinal ends of a respective tympanum 21.
- the tympani 21 are also supported by the side beams 1 and are interposed between ends of spaced roofing beams 4 arranged side by side, as more clearly illustrated in figure 1.
- Each tympanum has a base 22 for resting on the respective side beam 1, from which a central slab-like body 23 rises; the ridges 20 extend from the longitudinal ends of said body, which has a curved upper edge.
- the central slab-like body 23 defines, together with the resting base 22, an acute angle whose breadth is equal to the one delimited by the head 17.
- the upper curved edge of the tympanum 21 has a radius of curvature which is equal to the one of the roofing panels 11.
- a curved plate-like element 24 extends from said upper edge and has, on a free edge, a stiffening ridge 24a.
- the extrados of the roofing panel 11 adheres on the latter, which delimits the insulation 12 and the waterproofing 13; said extrados can be fixed, for example by means of nails and the like, as previously shown for the ridges 9 and 10 of the roofing beam 4.
- Each roofing beam 4 has a width of approximately 1.20 meters and a length comprised between 12 and 26 meters, while its height is comprised between 0.93 and 0.96 meters.
- a roofing beam form which comprises a base frame, defined by means of segments 25 which can be joined in order to obtain preset lengths of roofing beams 4.
- Movable heads 26 are fixed to the frame. The entire form is in contact with a supporting surface by means of shock-absorbing feet 27.
- Means for the movement of an elongated longitudinally extended filler body 29 are movably associated on a first wall or side 28 of the base frame; said filler body penetrates within the form and can be rigidly coupled to a second wall or side 30 of the frame.
- the filler body 29 defines, in cooperation with curved ribs 31 supported by cross-members 32 and mechanically supported by pressers 33, the concave shape, as previously described, in the roofing beams 4 in a cross-section taken transversely to the extrados.
- the filler body 29 in fact has surfaces which penetrate within the form and have a convex shape which is complementary to the concave shape of the roofing beam.
- the ribs 31 are mechanically loaded in order to counterbalance the thrusts of the concrete and transmit vibration during the casting step.
- the filler body 29 is loaded by means of the snap-action traction element 37 which has a neutral point.
- the block 8c is inserted beforehand and is kept in position by spacers which are connected either to the filler body or to the reinforcement frame.
- the movement means comprise a piston-and-cylinder unit 34 which is pivoted to a lower portion of the base frame.
- the piston 35 of the unit 34 is instead pivoted to a bar 36 which extends from a lateral edge of the filler body 29 which is pivoted to the first side 28.
- the filler body 29 is fixed to the second side 30 for example by means of the traction element 37 which is fixed to the edge of the filler body which engages a hook 38 which is fixed to the second side 30.
- the radius of curvature of the ribs 31 and the walls of the filler body 29 is such as to keep constant the radius of curvature of the wings of the roofing beam 4 along its entire longitudinal extension. Furthermore, the filler body 29, and most of all its above described movement means, allow to extract the filler body 29 from the form without altering in any way the wing of the roofing beam 4 which is on the side of the snap-action traction element 37 of the filler body.
- a first roofing beam 4 is initially arranged on said beams, followed by a second roofing beam 4 at a preset distance and parallel to the preceding one.
- the tympani 21 are then inserted on the heads 17 of the roofing beams 4, making the ridges 20 enter the respective accommodation seats 19.
- the roofing panels 11 are arranged between the two roofing beams 4 and are nailed to both ridges 9 and 10 of the respective roofing beams 4.
- the drainage channel is defined by depositing a mat 39 of insulating material on both heads 17 and by then covering a portion of the beam 1, which is left uncovered by the mutually facing roofing beams 4, with another mat 40 of insulating material.
- the mats 39 and 40 are finally covered with a layer 41 of waterproofing material which forms, together with the waterproofing layer 13, a continuous waterproofing layer on the entire surface of the covering.
- the invention achieves the intended aim and objects, advantageously modifying the shape of the roofing beams in order to simplify their manufacture and installation, furthermore lightening them in order to improve their transportability and thus increase the commercial range of action of a factory for the production of such roofing beams.
- the lower weight allows to increase the distance of the pillars to 15-16 meters.
- the materials employed, as well as the dimensions, may be any according to the requirements.
