## Title
Mobile structure for adapting surfaces

## Abstract

The invention relates to a mobile structure for adapting surfaces, which is formed by a grid assembly (1) which is supported at grid nodes by telescopic columns (2) which can be individually extended in order to use the grid assembly (1) to form a variable surface comprising relief elements.

## Background
FIELD OF THE ART
The present invention relates to the configuration of relief surfaces, proposing a mobile support structure which allows selectively adapting and modifying the orography of large surfaces as desired.
STATE OF THE ART
There are constructive surface applications in which the orographic shape can have a special interest, support structures and/or variable fillings with construction materials conventionally being used for such purpose for determining the configurative reliefs of the different parts on the corresponding surfaces.
This conventional technique implies a constructive implementation virtually requiring sculpture work, determining fixed constructions, the modification of which generally forces a destruction or reconstruction of the interested parts, with the work, time and cost which this implies.
OBJECT OF THE INVENTION
According to the invention a structure is proposed which is developed according to constructive and functional features, which allow supporting surfaces in adaptation conditions for selectively forming the desired orography.
This structure object of the invention consists of a modular grid assembly which is supported with respect to the grid nodes by means of telescopic columns, the grid structure being formed by telescopic, longitudinal, transverse and diagonal ties, which are attached in a hinged manner on cores determining the grid nodes.
The ties of the modular grid assembly consist of a free telescopic formation between the component elements, insofar as the support columns individually have an actuation system for actuating the extension and retraction of the telescopic formation thereof. The actuation system of the telescopic columns, for such purpose, can be any type of those known in the current art, such as for example hydraulic, mechanical, electrical, etc., without this altering the concept.
A structural assembly is therefore obtained whereby, by means of the selective extension of the different support columns, a variable orographic surface configuration can be formed with the grid assembly, based on the different elevation of the multiple grid nodes, which can be automatically controlled by computer management depending on a programming corresponding with the shape to be made.
The dimension of the modular parts of the grid assembly can be variable, where appropriate, depending on the extension of the surface to be formed and on the detail of the shapes desired in the configuration.
The mentioned structural assembly is complemented with a covering determining the desired surface, which is formed on a support mat which is arranged on the grid assembly of the adaptable structure, said mat being formed according to an undulated formation in four directions, allowing to absorb the dimensional variations of the grid assembly in the different directions when the structure is adapted to the application surface shapes.
The gaps of the grid assembly are closed with sheet plates or the like, by means of which a continuous support for the undulated mat of the covering is determined, said plates being arranged according to a practical non-limiting solution, in a hinged attachment on diagonal ties of the grid assembly and supported with freedom to slide on telescopic crosspieces incorporated in the area of the vertex opposite the respective diagonal tie, which likewise allows absorbing the dimensional variations of the grid assembly in the adaptation of the structure to the application shapes.
The proposed structure therefore allows adapting the orographic configuration of any surface in a very simple manner, regardless of the dimensions and application, with the possibility of later modifying the formed surface with the same ease for its adaptation to other different shapes. In such conditions the structure can be applied both for horizontal surfaces and for vertical surfaces, allowing to adapt the orographic shape of floors and of walls.
Due to the above, said structure object of the invention has truly advantageous features, acquiring its own identity and a preferable character in the function for which it is intended.

DETAILED DESCRIPTION OF THE INVENTION
The object of the invention relates to a support structure intended for forming floor or wall surfaces, said structure comprising a constructive formation allowing an adaptation movement in order to configure the desired orographic shape of any surface.
The structure comprises (FIGS. 1 and 2) a grid assembly (1), which is supported with respect to the grid nodes by means of respective telescopic columns (2) having an individual actuation system (3) for extending their length.
The grid assembly (1) (FIGS. 3, 4 and 5) consists of a modular composition formed by longitudinal, transverse and diagonal ties (4), which are attached by means of hinges (5) on cores (6) forming the grid nodes, the mentioned ties (4) being structured according to a freely extending telescopic formation.
The grid assembly (1) can therefore be adapted as a surface extension, such that by means of longitudinally extending the columns (2), the cores (6) can be placed at different heights, allowing to configure with the mentioned grid assembly (1) variable shapes of a relief surface.
A covering (7), based on different materials and layers, can be placed on the mentioned structural assembly (FIG. 6) allowing to form a surface with the desired appearance and characteristics for any application.
According to a practical embodiment the covering (7) is arranged on a support mat (8), which is placed on the grid assembly (1), said mat (8) being structured with an undulated formation (8.1) in four directions, as shown in FIG. 7, such that it allows absorbing without stress the dimensional variations of the grid assembly (1) in the adaptation to the shapes of the application surfaces of the structure.
The gaps of said grid assembly (1) are covered with corresponding sheet plates (9) or the like for the uniform support of the mat (8) on the grid assembly (1), which plates, according to a practical embodiment, (FIGS. 3 and 5), are arranged in a hinged attachment on diagonal ties (4) of the mentioned grid assembly (1), and are supported with freedom to slide on telescopic crosspieces (10) arranged in the areas with the corresponding opposite vertices.
This arrangement of the closure of the gaps of the grid assembly (1) is non-limiting, and can be any other arrangement with the same effect in which the closing plates (9) are secured in the mounting, allowing the dimensional variation of the gaps of the grid assembly (1), such that the hinged attachment for securing said plates (9) can be provided on any of the sides there of, on the corresponding tie (4) of the grid assembly (1), whereas the other two sides are free to slide.
The modular formation of the grid assembly (1) of the proposed structure can be formed with modular parts of any dimension where appropriate, according to the extension and the shapes of the surfaces to be formed, such that the smaller the dimension of the modular parts forming said grid assembly (1), the greater the capacity of adaptation to complex shapes and with greater detail of the application surfaces.
The actuation system (3) for extending the telescopic columns (2) is individual for each of the columns (2), said actuation system (3) being able to be of any type (hydraulic, mechanical, electrical, etc.) of the known techniques, the entire assembly being controlled by a computer control means such that based on data programming in said control means, according to the shapes of the surface to be configured, the structure for forming the application surface is automatically adapted, which can subsequently be also transformed into other shapes with the entry of data corresponding to the new shape into the control means.
