The parabolic arch structurally is divided into three sections, by virtue of having two points of articulation to receive the diagonal bar or brace, which are reinforced with longitudinal and transverse plates to make the parabolic arch rigid at those points. The unions of the six sections are based on a female-male system, secured by transverse plates at their ends by a single screw and in turn, the triarco profile integrates at its ends drilled plates to achieve the union of the parabola with the unit doze

Description

MODULAR STRUCTURE REMOVABLE.

OBJECT OF THE INVENTION. The present invention corresponds to a removable and functional modular structure, developed to cover a considerable area of land without intermediate supports, and which due to its modular nature is adaptable to different space requirements and physical characteristics of land, which is an essential factor that the Unlike other structures developed for the same purpose.

BACKGROUND OF THE INVENTION.

Faced with the increasingly frequent organization of fairs, temporary exhibitions and many other activities that take place outdoors, which are regularly used to rent temporary roofs in the market, a removable module project was developed, whose characteristics exalt a greater versatility than those found in the market. In the literature, there are removable structures and modules such as the fixed and mobile structures developed by the company Ferrari SA, of Sedex France, which has many examples of applications among others: airports, stadiums, sports centers and bus terminals and which are combined structures with varied geometries such as: the hyperbolic paraboloid, the circular sections, the conoids and others. These structures are made up of supporting structural components of various materials ranging from light metals such as aluminum, to more resistant metals such as stainless steel and different alloys. In addition, they use suitable covers to adapt to the desired geometry which are made with combined materials such as polyvinyl, silk fibers and steel among other materials. There are other cases where these structures are found and which bear some similarity to that of the present invention in its geometry but not so, in its structural development and construction procedures, these structures are the following: • CANDELA AND HIS CASCARONES by Verlag Georg DW Callwey 1963. In this book, the works of Félix Candela are shown, which, even when they are concrete, exalts the handling of geometry and mainly of the hyperbolic paraboloid.

• STAR STRUCTURAL ARCHITECTURE (Mobile and fast assembly architecture), by Félix Escrig Pallares TECHNOLOGY RESEARCH GROUP ARCHITECTURAL OF THE UNIVERSITY OF SEVILLE 1997. It shows images of a stretched and framed cover like the one presented in the Expo Sevilla 92.

DESCRIPTION OF THE INVENTION.

The invention is described below, by means of the figures in order to be able to show this invention more clearly: Figure 1 corresponds to the parabolic arch formed by three tubes joined with small plates, forming a profile in the form of an equilateral triangle (l, a), whose main geometric characteristics are: the curvature of the tubes that is defined from a parabola centroidal (l, b) located in the centroid of the equilateral triangle and that goes along the parabolic arc, it is so that these curvatures (l, c) both lower and upper are "parallel" derivatives of this parabola. The parabolic arch is sectionable in six parts (l, d) for easy transport and fast assembly. The parabolic arc structurally speaking, is divided into three sections (l, e), by virtue of having two points of articulation (l, f) to receive the diagonal bar or brace, which are fully reinforced with longitudinal plates (l, g) and transverse (l, h) to stiffen the parabolic arc at those points. The union of the six sections is based on the male female system (l, i) secured by small transverse plates at their ends secured by a single screw which guarantees the safety and continuity of it. To achieve the union of the parabola with the support unit, the triarco profile integrates drilled plates at its ends (1 j).

Figure 2 corresponds to the support unit and its function is to transmit the forces generated in the module which are transmitted by the parabolic arcs to the ground. It consists of the following four components: a support plate (2, a) that is fixed by expansive tacks (2, b) to the ground, providing the necessary surface for the transmission of the load; two sets with articulation-bolts (2, c), for each end of the two parabolas that form the structure and that are perpendicular to each other. These supports, are integrated by tubes and bars whose design is based on the principle of concentration of forces in a point (bolt articulation), characteristic that gives the structure its condition of disassembly; the diagonal bolt (2, d) whose function is to join the two support groups stabilizing them in case of lateral stresses. The anchoring preparations (2, e) and (2, f); the first is to receive the cable of the diagonal parabola of the cover, by means of a perforated plate (2, e), which is welded to the diagonal bar bolt and two other plates bored to receive a tensioning cable, which is held by a plate -tope (2, f), which are welded to the inclined tubes of the support assemblies, said tensioning cable is routed through a small tube (2, g), which is welded to the vertical tubes, thereby maintaining the cable practically at ground level in cases where ground drilling is not authorized.

Figure 3, defines the diagonal bar or brace as a structural component that allows the stability of the module as a whole, is a rigid element with two articulated ends that work, both traction and compression, absorbing the efforts that transmit the arcs, caused by lateral thrusts and wind, its profile is composed of a tube and four plates welded in each of the quadrants of the bar (3, a), which increase their size as they reach the center, giving greater rigidity to the element. Their ends (3, b) are composed of drilled plates welded to the tube, to allow the passage of the bolt after having inserted it into the articulated points of the parabolic arch.

Figure 4 corresponds to the description of the dead-anchor, whose design responds to the various installation restrictions of the module that considers dead-ballast-mobile (4, a). This type of ballast is used when the excavation of the soil is not authorized, being necessary the placement of said containers, in such a way that when being filled with sand and / or gravel they provide the necessary weight to support the pull of the edge cables.

Figure 5 refers to the modular roof, which mainly defines its geometry that is based on a surface of double inverse curvature, namely of two hyperbolic paraboloids (5, a), which are intersected by the introduction of two tension cables ( 5, b) generating two diagonal parables, whose characteristics of height and covered area define the interior architectural space. Said modular cover is joined by its four lateral faces to what is known as tension cover flaps (5, c) corresponding to surfaces of hyperbolic paraboloid, which in turn integrates three removable door covers (5, d) with its surface on its surface. Same type of surface.

Figure 6 refers to the cover flap tensioner (6, a) which is constituted, in addition to this, three removable door covers (6, b) that placed with its system of closures, delimit access and provide the necessary protection against the weather. It is important to point out that the main function of the tension flap is to keep the module stable, by transmitting by lateral cables (6, c) the lateral forces generated towards the ground, both by the weight of the modular roof itself, and of the thrusts caused by earthquake and / or wind.
