The same pieces, or similar pieces, have been indicated with the same reference numbers in the drawings attached.

It will be noted that a lamellar beam structure according to the present invention comprises a number of metal plates lamellar 1 that are kept separated from each other by means of a panel or plate 3 made of plastic or wood material (figures 2 and 3) or made of any other convenient separator material other than metal. The lamellar metal lamellar plates 1 act as a reinforcing structure and support pieces.

The lamellar metal plates 1 can be place inside two lamellar plates or external panels of coating 3, which may or may not be of the same material as any of the other internal separator strips 3. The two plates external lamellar 3 act, first and foremost, to serve as a coating external to make the beam more attractive. It can be paint or, otherwise, decorate in various ways by means of fake marble or imitation wood, etc.

The embodiment illustrated in Figures 2 and 3 refers to lamellar beam structures according to the invention present, in which the lamellar separator plates 3 are all inside metal plates 1, where metal plates External lamellars are exposed beams plates.

Each of the metal lamellar plates 1 and the separators 2 and / or the covering or lining sheets 3 are they keep tightly tightened each other by means of a plurality of fastening means, for example, bolts, for example, a sleeve 4, threaded inside, which is inserted in all or in part of the thickness of the lamellar beam and is tightened between two bolts 5, whose heads react on their respective lamellar plate external 1 or 3 of the beam structure. In that case the structure will can disassemble quickly; however, they can also be used rivets, nails or similar fasteners.

In a joint, for example, a butt joint such as the one illustrated in figures 4 and 5, the plates (internal) separators 3, 3a are cut and an equal number of joining elements of metal (internal) plates 7 are inserted between the plates metal 1 and conveniently attached to the plates metallic 1, for example, by means of bolts, as illustrated in figure 4.

In the realization of the three-beam T-joint lamellar according to the present invention, as illustrated in the figure 6, there are two lamellar beams that connect at their ends, same than in the embodiment shown in figures 4 and 5, and Equipped with metal plates 8, longer than plate elements 7. An extension plate or tongue 9 projects from the head or distal end of the third lamellar beam that is located in a central position with respect to other plates lamellar 1 and 3a of the beam and welded at its distal end to a plate element 8 which may include two sections welded to the element 9. More particularly, the plate element 9 is projected from its respective lamellar beam a length that, approximately, corresponds to the thickness of the plate element 8 to which it is fixed, and thus the remaining lamellar plates of their respective beam they are in contact with the corresponding plate element 8.

The embodiment shown in Figure 7 is similar to that of figure 6, except that there are a couple of elements of extender plate welded to one end of it to an element of connection plate 8.

Three lamellar beams are illustrated in Figure 8 T-shaped connected to each other by means of a plate element of connection 8 and a pair of connection elements 10, in the form of square, each having a first tongue attached to one of the two beams, in contact alignment with each other, and a second tongue fixed to the third beam. The tabs of the elements in 10 square can be placed inside or outside the lamellar plates of the beam, as shown in the drawing.

A cross union of four lamellar beams, of according to the present invention and as illustrated in figure 9, it comprises three plate elements 7, the two elements being external plate fixed to a respective tongue 9, similar to the one It is shown in figure 6.

The realization of a butt joint, which shown in figure 10, is similar to that illustrated in figure 6, except that, instead of a plate element 8, it has been placed an anchor plate 10 that is fixed to another lamellar beam transverse or to a fixed support, while plate 10 can be, in turn, hold in place by means of screws 11.

Figure 11 shows a plate (external or internal) rectangular metal lamellar 1 in which they have been formed the holes 12 to receive their respective threaded sleeves Four.

Figure 12 shows two plates (internal or external) metal lamellar for two lamellar cantilever beams, according to the present invention, which are in contact and connected each other, at its protruding ends, by means of internal elements clamping 7. The metal lamellar plates are shaped like step on its lower edge and the lamellar ones are formed with a plurality of through holes 12 arranged to receive the sleeves 4.

Lamellar (internal or external) plates Metals 1 have a step-shaped configuration, as shown in figures 13 and 14. It is also possible to get together butt, with lamellar beams for stair sections, by means of anchor plates 10, as illustrated in Figures 15 and 16, or by half of one or more plate elements 7, as shown in the Figures 17 and 18.

The lamellar structure 13 that acts as a support and illustrated in figures 19 to 21 comprises three lamellar plates metallic 1, while the support 16, shown in the Figures 22 to 24, comprises four lamellar plates 1, which are separated, on top of them, by means of lamellar plates 1 of a cross lamellar beam 14 and, in the part bottom thereof, by means of a base clamp 15 with two vertical flanges 17 and spacers 2.

Figures 25 to 27 illustrate transverse means for connection between two or more lamellar beams according to the present invention. In the embodiment shown such means they comprise two tubes 18 with welded ends inside which They can be screwed into the respective tails of the beam. More in in particular, one of such tails may consist of a through bolt 5 with a head 6, on one side of the beam, and a stem that projects at the other end of it, on top of which you can screw a reinforcement 19 with a head 19a, threaded into its outer, for connection to one end of a cross tube 18.

Figures 26 and 27 also show two plates clamping 30 inserted between the lamellar plates 1 of a beam lamellar and secured in place by means of two bolts 5. The plates 30 extend in a vertical plane or perpendicular plane to the transverse connecting tubular elements 18 and are arranged to hold, for example, a parapet support 31.

Figures 28 to 30 illustrate a table 20 with a top or cover 21 of polished flat glass, wood, marble or similar and two sides with legs 22 consisting of a structure L-shaped lamellar turned up that is connected to in any manner that is convenient, as illustrated above, to two clamps, as shown in figure 12. The sides are connected to each other by three transverse tubular elements 23 placed under deck 21 and, if necessary, by means of two pieces in cross 24 on the table legs.

The flight of stairs that has two structures of lamellar beams, described above, illustrated in the drawings Attached, it is subject to numerous modifications and variations within the protective scope as defined in the claims.

Any reference signal following the technical characteristics in any claim have contributed to increase the intelligibility of the claim and not It should be interpreted as limiting the scope of the claim.
