    SPACE STRUCTURE FOR BUILDING COVERS
    5 Technical sector
    The present invention is related to the construction of building roofs that are formed by a spatial structure on which a panel covering is arranged, proposing in this regard a spatial structure developed with
    10 characteristics that simplify the assembly of the joint between the elements of the structure, with security of resistance and adaptability to surfaces that contain different planes.
    State of the art
    15 In the field of construction, building roofs that are formed with a spatial support structure and a covering with panels that can be of any type are known, this type of roof being used especially for its strength, stability and visual lightness, in constructions of great lights.
    The spatial support structures used in said roofs are generally formed according to a reticular architecture composed of structural bars that are joined radially over nodes, determining a mesh of triangular, rectangular or any other polygonal shapes.
    25 In that sense, document EP0072139 discloses, for example, a knot for spatial structures that is formed with a tubular core, on which radial bars are attached that are fixed to the tubular core by means of connectors that are screwed to the radial bars and the tubular core. This solution is suitable for forming flat spatial structures, but does not have the geometric versatility necessary to form
    30 spatial structures that adapt to surfaces that contain different planes.
    Solutions of spatial structures have also been developed in which the union between the structural bars and the knots of the meshes is established in a versatile manner, thus allowing the adaptation of the spatial structures for roofs of different surface configurations, with adequate resistance conditions of the

    same.
    In that sense, document US2007 / 0125033 discloses a node for spatial structures formed by a core comprising two parallel discs with chamfers in the periphery that determine faces facing, on which radial bars are joined that incorporate joined by welding in the ends, connectors that are fixed by screwing on the discs of the core. These connectors, in turn, are made up of 3 independent pieces welded together, creating an assembly that ends up welding on the ends of the radial bars. This involves expensive and low precision manufacturing, due to the multiple welding required. Precision is of great importance since the radial bars rest against the discs by means of said assemblies. In this case, each connector is also determined with an opening to introduce the fixing screws to the core discs and to be able to act on said screws, which reduces their resistance.
    Document ES2317818 discloses an embodiment that reduces the inaccuracy problems of the previous solution, due to the multiple welds to incorporate the connecting bars of the radial bars on the core of the nodes of the spatial structures. This document proposes the union between the radial bars and the disks of the core of the structural nodes, directly by means of screws that pass through a cover fixed by welding on the end of the corresponding bar. Each of the screws has in its length two zones of different diameter threaded in opposite directions, with the incorporation of two parallel nuts in the rear threaded area which is the one with the largest diameter. In this way, each of the screws can be screwed until they stop in the fixation on the corresponding disk of the core of the structural knot, one of the nuts acting in a counter-nut position with respect to the other nut, and then fixing the immobility of the screw by tightening the two nuts against the end cap of the corresponding bar. This solution has a disadvantage of manufacturing complexity of the necessary screws, in addition to working the flexural screws, a way for which they are not designed, and limiting the tightening of the joint to a slower and manual way . Finally, it should be noted that the union screws are exposed in the application structures, with the possibility of damage by external agents.
    Object of the invention

    According to the invention, a spatial structure for building roofs is proposed, developed with structural characteristics that simplify and speed up the assembly, increase the rigidity in the joints to reticular nodes of the structure, economize on manufacturing and increase the durability of the joints. .
    This structure object of the invention comprises a conventional reticular formation composed of tubular bars that join radially with respect to the reticular nodes formed by discs. The disks have on the periphery chamfers determining faces facing, so that the joints between the radial bars and the disks of said knots are versatile, allowing the formation of structural surfaces defined according to panels arranged according to different planes. The faces facing each other do not have to be parallel to a central longitudinal axis of the discs, that is, they may or may not form an angle with respect to said axis. The reticular nodes comprise two of the discs, which may be joined or be two independent parts of each other.
    According to the invention, the tubular bars of the spatial structure are closed at each end with a cover, preferably configured as a plate, which is fixed to the tubular bar by welding. Screws with which the union of the bar with respect to the corresponding knot discs in the spatial structure of application are arranged through through holes of said cover, separating caps covering the screws are incorporated on the screws . With the space structure mounted, the separation bushings are interspersed between the bar cover and the corresponding knot disk, establishing a separation. The relative position of the separation bushings with respect to the plates is fixed as they are subjected to compression by screwing the screws into the discs.
    The tubular bars are also determined in the proximity of each end with an opening in one of the faces, through which the screws for joining the bar with respect to the corresponding reticular knot discs can be introduced into the spatial structure of application, as well as manipulate said screws to tighten them.
    In this way, the union between the tubular bars and the discs of the nodes of the spatial structure is done by commercial single-threaded screws. In this way, the screws used are economical and with guaranteed traceability and quality. Likewise,

    The use of these screws means facilitating the drive for the mounting of the tubular bars on the reticular nodes in the application structures. On the other hand, said separation bushes act as stops in the union of the tubular bars on the disks of the reticular nodes, reducing the flexural stress supported by the screws, when part of said effort is transmitted to the bushing while adding additional stiffness to the the joint once the appropriate tightening torque is introduced.
    The separation bushes comprise a longitudinal extension and an outer diameter, which provide versatility to the spatial structure in adapting to different configurations, optimizing the size of the disk that prevents interference between adjacent bars. The longitudinal extension is determinable by a simple cross-section of the separation bushes.
    The openings for inserting and manipulating the screws are made in the tubular bars, whereby said openings do not weaken elements arranged between the tubular bars and the reticular nodes in the application space structures. Likewise, the openings allow access to both manual and automatic tools for quick and controlled screw tightening. The location of the openings in the tubular bars, rather than in elements arranged between the tubular bars and the reticular nodes, is advantageous since it is easier and more reliable to control the structural failure in the tubular bars than in elements arranged between the tubular bars and reticular nodes. Additionally, the openings allow the application of surface treatments, such as galvanization, that face the most aggressive environments.
    It is also provided that, once the tubular bars are fastened in the application assembly, the openings of the tubular bars for inserting and manipulating the screws are closed with a cover fixed on the tubular bars. The covers allow to protect the screw heads, as well as the interior space of the tubular bars, against external influences.
    Therefore, the spatial structure object of the invention results from assembly, rigidity, manufacturing and precision characteristics that make it advantageous, acquiring its own life and preferential character with respect to the conventional spatial structures of the same application.

    20 Detailed Description of the Invention
    The object of the invention relates to a spatial structure for forming building roofs, the structure comprising a reticular formation composed of tubular bars (1) that join radially on reticular nodes formed by discs (2)
    25 provided on the periphery with chamfers (3) that determine faces facing, on which the clamping of the tubular bars (1) is established in such a way that it allows to configure structures with variable surfaces in different planes. The faces shown may or may not be parallel to a central longitudinal axis of the discs (not shown in the figures); that is, they can form an angle with respect to said axis.
    30 The tubular bars (1), which can be obtained by cutting to the desired longitudinal length from bars of great length, are closed at each end with a cover (4) that is fixed on the bar tubular (1) by welding. The cover (4) is preferably configured as a plate.

    Said tubular bars (1), provided with the corresponding closing caps (4) at their ends, are attached to the disks (2) of the reticular nodes in the spatial structure of application, by means of screws (5) that pass through of holes (6) of the covers (4). The screws (5) pass through said holes (6) to screw into threaded holes
    (7) of the faces shown by the chamfers (3) on the periphery of the aforementioned discs (2) of the reticular nodes, the head (8) of the screws (5) remaining inside the corresponding tubular bar (1). Additionally, inside the tubular bar (1), stop washers (9) can be incorporated between said heads (8) of the screws (5) and the respective cover (4) of the tubular bar (1).
    In that mounting arrangement of the clamp of the tubular bars (1), separation bushes (10) with through hole (10 ') are arranged between the cover (4) of the end of the tubular bar (1) and the disc (2) of the corresponding reticular node, passing the screws (5) through the through holes (10 ') of said bushings (10). Thus the screws
    (5) of the joints are completely hidden and protected in the spatial structure of application, being able to determine the fastenings of the tubular bars (1) with a total flexibility to configure the space structures as appropriate, without prejudice to the resistance. To improve the seat of the separation bushings (10) on the chamfers
    (3) of the disks (2) of the structural nodes, the separation bushes (10) can also be complemented with a support (11) supporting the seat.
    For the incorporation and actuation of the screws (5) in the construction assembly of the application space structures, the tubular bars (1) have near each end an opening (12) defined in a face of the tubular bar (1 ). In this way, through said openings (12), the screws (5) can be introduced and their tightening can be performed, without affecting the resistance of the clamping couplings, since the openings (12) are in the bars tubular (1) and do not weaken the fasteners.
    It is envisaged that, once the mounting of the tubular bars (1) in the application space structures, the openings (12) for insertion and actuation of the screws (5), can be closed by means of respective covers (16) . These covers (16) can be fixed to the corresponding tubular bar (1), thus leaving both the inside of the structural bar (1) and the heads (8) of the screws (5) hidden and protected from external agents.
    5 10 The spatial structure is completed with panels (13), in order to form the building roof. The panels (13) can be made of glass. Preferably, the panels (13) are joined together by silicone cords (14) in order to establish a seal. The panels (13) are arranged in the spatial structure through coupling elements (15) included in the spatial structure. According to an exemplary embodiment, seen in Figure 6, the coupling elements (15) comprise an elastic element (15.1), such as a rubber, and a separator (15.2). The elastic element (15.1) is for resting the panels (13) and the separator (15.2), configured in a "U" shape and preferably of aluminum, is to cope with thermal expansion of the panels (13).
