Referring to the drawings, Figures 1 to 3 show a scenario S1 and a first form of structure of construction consisting of a framework covered by sheet material. Scenario S1 is the smallest of the five standard stage sizes, ie it has a width Usable 15 m. The frame has a body section main A, a domed rear end section B and a section front overhang C. The main section A consists of three arches 1, the domed end section B is constituted by an arc 1 and three sections of arc 2, and the extreme section in cantilever C is constituted by an arc 3. Each of the arches 1 it has a light of 15 m, and is constituted by a pair of beams of support 4, four main beams 5 and two secondary beams 6. The secondary beams 6 are positioned symmetrically, and each is located between a respective pair of main beams 5. Each one of the beams 4, 5 and 6 is a composite lattice beam, it is say it has a front bead 7 and a rear bead 8 cabled each other by means of straps 8a that intersect with the two laces at 45º angles. Laces 7 and 8 and suspenders 8a are aluminum tubes. Laces 7 and 8 each have a section Transversal generally rectangular as shown. The beams 5 they are all 3.27 meters long, beams 6 have a length of 2,034 meters, and beams 4 have a height of 3,650 meters

Laces 7 of each pair of adjacent beams are connected to each other by means of an articulated joint respective (see Figure 6). Similarly, the laces 8 of each pair of adjacent beams are connected to each other by means of a joint respective articulated of this type. So, as shown in the Figure 6, two adjacent strands 7 are connected to each other by an articulated joint consisting of castings of aluminum joint 7a and 7b. The joint casting 7a consists of a pair of parallel shaped joints of D that intertwine with a pair of parallel joints in D shape of the joint casting 7b. A pin 7c, passing through aligned openings in the joints, complete the articulated joint, so that the cords 7 can pivot about in relation to others.

The domed end section B is constituted by three sections of arc 2, each of which is identical to one half of an arc 1, that is to say it consists of a beam of bra 4, a pair of main beams 5 and a secondary beam 6, the secondary beam being positioned between the two beams main.

The arc 3 of the front section C is identical to each of the arches 1, except that the main beams 5 adjacent to support beams 4 are tilted forward 25, as best seen in Figure 2.

As shown in Figure 5, each cord 7 it is provided with an anchor section 9 which is a mounting sliding within a pair of tabs 10 extending towards outside formed on the outer surface of the cord. The section of anchor 9 defines a pair of slots 11 that have access openings They give opposite directions. Similarly, laces 7 and 8 are formed on their inner surfaces with respective pairs of tabs 10 extending outward to receive the ends of the straps 8a.

Each pair of adjacent arches 1 of the section of the main body A is provided with a band 12 of fabric coated with polyvinyl chloride. Similarly, bands 13 of this material are provided at ends B and C of the structure between members of adjacent arches, and a band 14 is provided between the rear arc 1 of the main body section A and the arc 1 of the domed end section B. Each band 12 to 14 is provided, on each side edge thereof, with flange 15 that can  slide through slots 11 of anchor sections 9 (see Figure 5). Thus, bands 12 to 14 can slide to their position, to cover the entire area between respective arcs 1 or members of arches. To stretch the material of bands 12 to 14 for the purpose of increasing the strength of the structure finished, each band has a width that is slightly smaller to the width between the arcs or members of corresponding arches. Also, the ends of each band 12 to 14 are connected to the 1 arcs or corresponding arc members to be under tension longitudinally.

The provision of anchor sections 9 helps to the standardization of the structure, because laces 7 and 8 They are all of the same cross section. Thus, bands 12 to 14 can be attached to arches and arc sections without having to provide sections of special cords to receive the flanges 15. On the other hand, providing the strands 7 of each bow or arch section of a single continuous anchor section 9, any water that enters its slots 11 is discharged by grooves to the ground, and thus can not get inside by the joints between the beams.

Figure 7a shows a scenario S2 and a Second form of construction structure. The S2 scenario is the second smallest of the five standard stage sizes, is say it has a usable width of 18 m. The structure of construction is similar to that of Figures 1 to 5, because it has a main body section A, a rear end section vaulted B and a front section in cantilever C. In addition, the main section A consists of three arches 21, the section vaulted end B is constituted by an arc 21 and four arc sections 22, and the cantilever end section C is constituted by an arc 23. Each of the arches 21 has a light 18 m, and consists of a pair of support beams 4, four main beams 5 and two secondary beams 26. The beams Secondary 26 are positioned symmetrically, and each is located between a respective pair of main beams 5. As with the first form of construction structure, each of the beams 4, 5 and 26 is a composite lattice beam. The beams 5 have all 3.27 meters long, and beams 4 have a height of 3,650 meters.

Each of the arc sections 22 of the domed end section B is identical to one half of an arc 21. Similarly, the arc 23 of the front section C is identical to each one of the arches 21, except that the main beams 5 adjacent to the support beams 4 are inclined forward 25 °.

The construction structure shown in the Figure 7b has a light of 21 m, and is intended for use with a scenario S3 which is the third smallest of the five sizes of standard scenario, that is to say it has a usable width of 21 m. This structure is similar to the first form of structure, but each of its arches 31 is constituted by a pair of beams of support 4, six main beams 5 and two secondary beams 36. The support beams 4 and main beams 5 are identical to those of the previous embodiments. The beams 26 are positioned symmetrically, and are fixed to the main beams 5 that are fixed to the support beams 4. The domed end section B of this construction structure has an arc 31 and four sections of arc 32, each of which is identical to one half of a arch 31.

The construction structure shown in the Figure 7c has a light of 24 m, and is intended for use with a scenario S4 which is the second largest of the five sizes of standard scenario, that is to say it has a usable width of 24 m. This structure is similar to the first form of structure, but each of its arches 41 is constituted by a pair of beams of support 4, eight main beams 5, and two secondary beams 46. The support beams 4 and main beams 5 are identical to those of previous embodiments. The domed end section B has a arch 41 and five sections of arch 42, each of which is identical to one half of an arc 41.

Finally, the construction structure in the Figure 7d has a light of 29 m, and is intended for use with a scenario S5 which is the largest of the five stage sizes standard, that is to say it has a usable width of 29 m. This structure is similar to the first form of structure, but each one of its arches 51 is constituted by a pair of support beams 4, and ten main beams 5. Support beams 4 and beams main 5 are identical to those of previous embodiments. The vaulted end section B is constituted by an arc 51 and seven arc sections 52, each of which is identical to one half of an arch 51.

Therefore, it will be clear that they can build the five standard stage sizes using a small number of basic components, namely the support beams 4, the main beams 5 and the secondary beams 6, 26 and 36. The construction structure of Figures 7d and 8 can be considered which is the basic structure, because it uses only two components basic, namely two support beams 4 and ten main beams 5. The other four building structure frames use basically the same components, but replacing two or more of the main beams with a pair of special beams for each construction structure
