La presente invención, según se expresa en el enunciado de esta memoria descriptiva, se refiere a una estructura modular para la conformación de encofrados sumergidos, destinada más específicamente para la construcción de zapatas de hormigón que actúan de base para las pilastras de puentes sobre lechos fluviales, marinos, aluviales, etc.The present invention, as expressed in the set forth in this specification, refers to a structure modular for shaping submerged formwork, intended more specifically for the construction of concrete shoes that act as a basis for bridge pilasters on river beds, marine, alluvial, etc.

Así pues, en determinadas circunstancias la generación de una zapata de hormigón en zonas de elevado nivel freático, cauces de ríos, lagos, etc.; requiere complejas y arduas tareas de encofrado para crear paredes de hormigón y desaguado de la zona interior donde se generará dicha zapata.Thus, in certain circumstances the generation of a concrete shoe in high level areas water table, riverbeds, lakes, etc .; requires complex and arduous formwork to create concrete walls and drained from the interior area where said shoe will be generated.

Para evitar estos inconvenientes citados que en ocasiones obliga a cambiar el desarrollo de la obra y/o ralentizar su ejecución por los problemas de hormigonado en zonas inundadas se ha desarrollado la estructura modular de la invención.To avoid these inconveniences cited that in Sometimes forces to change the development of the work and / or slow down its execution due to concrete problems in flooded areas He has developed the modular structure of the invention.

Antecedentes de la invenciónBackground of the invention

En la actualidad para llevar a cabo la formación de encofrados sumergidos y más concretamente la formación de zapatas de hormigón que actúen de base para las pilastras de puente sobre lechos fluviales, marinos, aluviales, tal como se ha referido en el apartado anterior, en determinadas circunstancias la generación de una zapata de hormigón en zonas de elevado nivel freático, cauces de ríos, lagos, etc., requiere actualmente complejas y arduas tareas de encofrado para crear paredes de hormigón y desaguado de la zona interior donde se generará dicha zapata.Currently to carry out the training submerged formwork and more specifically the formation of shoes of concrete acting as a basis for bridge pilasters on river beds, marine, alluvial, as referred to in the previous section, in certain circumstances the generation of a concrete shoe in areas of high water table, channels of rivers, lakes, etc., currently require complex and arduous tasks of formwork to create concrete walls and drained from the area interior where said shoe will be generated.

Descripción de la invenciónDescription of the invention

Con el fin de alcanzar los objetivos y evitar los inconvenientes mencionados en los apartados anteriores, la invención propone una estructura modular para la formación de encofrados sumergidos que se caracteriza porque comprende módulos de doble pared, con medios de unión entre ellos para conformar un contorno cerrado de paredes laterales de cualquier geometría que se precise, de manera que los distintos módulos de doble pared se unen mediante unos característicos medios.In order to achieve the objectives and avoid the drawbacks mentioned in the previous sections, the invention proposes a modular structure for the formation of submerged formwork characterized by comprising modules of double wall, with joining means between them to form a closed contour of side walls of any geometry that precise, so that the different double wall modules are joined by means of characteristic means.

Así pues, la estructura modular está compuesta por piezas de doble pared arriostradas interiormente para soportar la presión del relleno interior de hormigón y acoplables entre sí, para formar un espacio central que coincidirá con la zapata a hormigonar.Thus, the modular structure is composed by double wall pieces braced inside to support the pressure of the interior concrete filling and attachable with each other, to form a central space that will match the shoe to concrete

Tal como se ha repreferido anteriormente, los módulos pueden generar cualquier geometría final comprendiendo medios de conexión entre los distintos módulos adyacentes.As previously described, the modules can generate any final geometry comprising connection means between the different adjacent modules.

El funcionamiento es sencillo al consistir en situar la estructura cerrada sobre una base pre-hormigonada o sin hormigonar, en cuyo caso la pared interior de los módulos será ligeramente más corta que la exterior, es decir, que el borde inferior de la citada pared interior estará separada del suelo a una altura determinada correspondiente con el espesor de la base de hormigón que se generará después, para dar así continuidad a la masa de hormigón.The operation is simple because it consists of place the closed structure on a base pre-concreted or without concreting, in which case the inner wall of the modules will be slightly shorter than the exterior, that is, that the lower edge of said wall inside will be separated from the ground at a certain height corresponding to the thickness of the concrete base that will generate later, to give continuity to the mass of concrete.

Posteriormente se vierte la masa de hormigón en el espacio intermedio delimitado entre las paredes de los módulos rellenando los laterales para formar una pared perimetral cerrada, y la base en el caso de que no exista el citado lecho pre-hormigonado.Subsequently the concrete mass is poured into the intermediate space delimited between the walls of the modules filling the sides to form a closed perimeter wall, and the basis in the event that the said bed does not exist pre-concreting

En ambos casos, logramos crear una estructura de hormigón a modo de cajón formado por paredes laterales y fondo, abierto superiormente y estanco, para el vertido y formación de la zapata, y cubierta lateralmente por la estructura del dispositivo en cuestión que queda perdido.In both cases, we managed to create a structure of concrete as a drawer formed by side walls and bottom, open superior and tight, for the pouring and formation of the shoe, and covered laterally by the structure of the device in issue that is lost.

Posteriormente, se procederá a extraer el agua y a efectuar las labores de trabajos en el interior, colocación de ferralla, descabezado de pilotes, o cualquier otra actividad tal como el encepado con unos pilotes.Subsequently, the water will be extracted and to carry out the work of work inside, placement of ferralla, pileheads, or any other such activity Like the pile with some piles.

Descripción de la forma de realización preferidaDescription of the preferred embodiment

Considerando la numeración adoptada en las figuras, la estructura modular para la formación de encofrados sumergidos se determina a partir de unos módulos, rectos 1 y angulares 1', de doble pared: exterior 2 e interior 3, con arriostramientos internos 4 para soportar la presión de la masa de hormigón que se verterá cuando corresponda en el hueco intermedio 5 delimitado entre tales paredes 2 y 3 de los módulos, una vez conformada toda la estructura modular de contorno cerrado que delimita un espacio central 6 que coincidirá con la zapata a hormigonar en correspondencia con el fondo de ese espacio central 6.Considering the numbering adopted in the figures, the modular structure for formwork submerged is determined from some modules, straight 1 and angles 1 ', double wall: exterior 2 and interior 3, with internal bracings 4 to withstand the pressure of the mass of concrete to be poured when appropriate in intermediate gap 5 delimited between such walls 2 and 3 of the modules, once conformed all the modular structure of closed contour that delimits a central space 6 that will coincide with the shoe concreting in correspondence with the bottom of that central space 6.

Así pues, la estructura modular de contorno cerrado se puede situar en un primer caso sobre una base hormigonada 7 y en un segundo caso sobre una superficie inferior 8 sin hormigonar para dar continuidad al hormigón correspondiente con el fondo del espacio central 6. En este segundo caso, las paredes internas 3 de los módulos 1 serán más cortas, de manera que su borde inferior estará situado por encima de esa superficie interior 8 sin hormigonar.So, the modular contour structure closed can be placed in a first case on a concrete base 7 and in a second case on a lower surface 8 without concreting to give continuity to the corresponding concrete with the bottom of the central space 6. In this second case, the walls internal 3 of the modules 1 will be shorter, so that its edge bottom will be located above that inner surface 8 without concrete

A continuación, una vez armada la estructura modular de contorno cerrado, se procede al relleno de la masa de hormigón para rellenar el hueco intermedio 5 delimitado entre las dobles paredes 2 y 3 de los módulos 1 y también el lecho del fondo del espacio central 6 cuando se trata de la superficie inferior sin hormigonar.Then, once the structure is armed closed contour modular, we proceed to the filling of the mass of concrete to fill the intermediate gap 5 delimited between the double walls 2 and 3 of modules 1 and also the bottom bed of the central space 6 when it comes to the lower surface without concrete

En ambos casos, logramos crear una estructura de hormigón a modo de cajón formado por paredes laterales y fondo abierto superiormente y estanco, para el vertido formación de la zapata, y cubierta lateralmente por la estructura modular de la invención que quedará perdida.In both cases, we managed to create a structure of concrete as a drawer formed by side walls and bottom open superior and tight, for the pouring formation of the shoe, and covered laterally by the modular structure of the invention that will be lost.

Posteriormente se procede a extraer el agua y a efectuar las labores de encepado con unos pilotes 9, tal como se ha referido en apartados anteriores.Subsequently, the water is extracted and perform the work of piling with some piles 9, as it has been referred to in previous sections.

Por otro lado, las distintas paredes 2 y 3 de los módulos 1-1' cuentan con una pletinas extremas perpendiculares 10 que contactan entre sí cuando se montan módulos adyacentes 1-1' incluyendo dichas pletinas extremas perpendiculares 10 perforaciones enfrentadas 11 para asegurar su fijación mediante elementos de sujeción no representados en las figuras. La fijación de las pletinas extremas perpendiculares 10 se refuerza mediante unas pequeñas cartelas 12.On the other hand, the different walls 2 and 3 of 1-1 'modules feature an extreme plates perpendicular 10 that contact each other when assembling modules adjacent 1-1 'including said end plates perpendicular 10 perforations facing 11 to ensure their fixing by fasteners not represented in the figures. The fixation of the perpendicular end plates 10 is reinforced by small cartels 12.

Para reforzar la unión entre módulos 1-1' se han previsto pares de soportes superiores 13 provistos de orificios enfrentados 14 por donde se introducen unas varillas roscadas 15 donde se acoplan una tuerca 16 con interposición de una arandela 17.To reinforce the connection between modules 1-1 'pairs of upper supports are provided 13 provided with facing holes 14 where some are introduced threaded rods 15 where a nut 16 is coupled with interposition of a washer 17.

En la parte inferior de los módulos 1-1' se han previsto unos tornillos verticales 18 acoplados en tuercas 19 solidarias de las paredes exteriores 2 de los módulos 1-1' para nivelar y posicionar en altura relativamente los módulos entre sí.At the bottom of the modules 1-1 'vertical screws 18 are provided coupled in nuts 19 integral with the outer walls 2 of 1-1 'modules to level and position in height relatively modules with each other.
