De acuerdo con las figuras, la presente invención se refiere a una viga para soporte de tableros de encofrado que se compone de un elemento tubular de chapa de acero de extremos abiertos y cuya sección transversal presenta una forma general rectangular en la que se ha designado la base con el numeral (1), las caras laterales con los numerales (2) y (3) y presentando la cara superior dos zonas simétricas (4) y (5) que delimitan un saliente central (6) con una cara superior plana (7) y caras laterales (8) y (9). Las zonas (4) y (5) son ligeramente inclinadas hacia abajo para permitir la fácil basculación de los tableros de encofrado en el momento de su desmontaje, a lo que contribuye igualmente la ligera inclinación hacia adentro de las caras laterales (8) y (9). A efectos de refuerzo, las zonas (4) y (5) presentan sendos nervios longitudinales (10) y (11).According to the figures, this invention relates to a beam for supporting boards formwork consisting of a tubular steel plate element with open ends and whose cross section has a shape general rectangular in which the base with the numeral has been designated (1), the lateral faces with the numerals (2) and (3) and presenting the upper face two symmetrical zones (4) and (5) that delimit a central projection (6) with a flat top face (7) and faces lateral (8) and (9). Zones (4) and (5) are slightly inclined down to allow easy tilting of the boards formwork at the time of disassembly, to which it contributes also the slight inward inclination of the faces lateral (8) and (9). For reinforcement purposes, zones (4) and (5) they have two longitudinal nerves (10) and (11).

También las caras laterales (2) y (3) presentan una ligera inclinación hacia adentro terminando inferiormente en pequeñas zonas verticales (12) y (13) con intermedio de sendos nervios (14) y (15).Also the lateral faces (2) and (3) have a slight inward inclination ending inferiorly in small vertical zones (12) and (13) with two nerves (14) and (15).

La base inferior (1) presenta marcados nervios longitudinales de refuerzo (16) y (17).The lower base (1) has marked nerves longitudinal reinforcement (16) and (17).

Uno de los extremos abiertos de la viga lleva adaptado un puente en U cuya base inferior (18) queda adaptada mediante soldadura a la cara externa de la base (1) y cuyas paredes laterales, en forma de sendas cartelas (19) y (20), quedan adaptadas y unidas por soldadura a las caras externas de los laterales (2) y (3) de la viga, sobresaliendo por la parte frontal, tal como es posible apreciar en la figura 2.One of the open ends of the beam carries adapted a U bridge whose lower base (18) is adapted by welding to the external face of the base (1) and whose walls lateral, in the form of two posters (19) and (20), remain adapted and welded together to the external faces of the sides (2) and (3) of the beam, protruding from the front, as it is possible to see in figure 2.

Para mejorar la entrada del otro terminal las cartelas (19) y (20) presentan una cortas pestañas (21) y (22) en la parte frontal inclinada, dirigidas hacia afuera, formando un abocardamiento que facilita la entrada del terminal conjugado. Dicho abocardamiento podría quedar realizado de cualquier otra forma, por ejemplo, mediante aletas laterales abocardadas de la viga.To improve the input of the other terminal the posters (19) and (20) have a short eyelash (21) and (22) in the inclined front part, directed outward, forming a flare that facilitates the entry of the conjugate terminal. Saying flare up could be done in any other way, by example, by means of flared lateral wings of the beam.

La cara inferior (18) del refuerzo en forma de U presenta también amplios nervios laterales de refuerzo (23) y (24).The underside (18) of the U-shaped reinforcement it also has wide lateral reinforcement ribs (23) and (24).

La pared inferior del escudo (18) presenta asimismo una ranura transversal (25) determinada por una abertura del propio escudo y el borde frontal del lado inferior (1) de la viga. Dicha abertura está destinada a recibir un saliente o elemento macho, que se describirá más adelante, del otro terminal o terminal macho de la viga. Dicha abertura (25) podría quedar realizada de cualquier otra forma apropiada, por ejemplo, en una aleta saliente de la cara inferior de la viga.The bottom wall of the shield (18) presents also a transverse groove (25) determined by an opening of the shield itself and the front edge of the lower side (1) of the beam. Said opening is intended to receive a projection or male element, which will be described later, of the other terminal or male beam terminal. Said opening (25) could remain performed in any other appropriate way, for example, in a protruding fin of the underside of the beam.

Dicho terminal macho es el que se observa en las figuras 4 y 5. En un caso preferente, la abertura correspondiente de la viga queda cerrada parcialmente por una placa o escudo frontal (26) soldado en el borde frontal del lado superior (7) y del lado inferior (1) del elemento tubular que constituye la viga. Dicho escudo (26) sobresale inferiormente estando destinado a coincidir en la ranura (25) de la viga en el momento de efectuar el acoplamiento del extremo de una viga con el de una viga adyacente. Ello se puede observar en la figura 6, en la que se observan dos vigas indicadas de modo general con los numerales (27) y (28) en la posición en la que el extremo inferior del escudo frontal, que se ha indicado con el numeral (29), se introduce en la correspondiente abertura equivalente a la abertura (25) de la figura 2 del terminal conjugado de la otra viga. Esta disposición corresponderá tanto al montaje como al desmontaje, que se observa en el detalle de la figura 6.Said male terminal is the one observed in the Figures 4 and 5. In a preferred case, the corresponding opening of the beam is partially closed by a plate or front shield (26) welded on the front edge of the upper side (7) and the side bottom (1) of the tubular element constituting the beam. Saying shield (26) protrudes inferiorly being intended to match in the groove (25) of the beam at the time of coupling of the end of a beam with that of an adjacent beam. This can be seen in Figure 6, in which two are observed beams indicated in a general way with the numerals (27) and (28) in the position in which the lower end of the front shield, which has been indicated with numeral (29), it is entered in the corresponding opening equivalent to the opening (25) of figure 2 of the terminal conjugate of the other beam. This provision will correspond both to assembly as to disassembly, which can be seen in the detail of the figure 6.

El saliente inferior (26) podría quedar realizado de otro modo, por ejemplo, por doblado de una aleta frontal de la viga.The lower projection (26) could be otherwise performed, for example, by bending a fin front of the beam.

Mediante la disposición que se ha explicado se posibilita la construcción de las vigas para soporte de tableros de encofrado con gran simplicidad y economía, a la vez que gran resistencia mecánica. El montaje resulta muy simple al coincidir el saliente terminal de una viga en la ranura que presenta el extremo conjugado de la viga siguiente y ello permite un fácil montaje y desmontaje. De igual manera la estructura de inclinación y nervios de lados del elemento tubular constitutivo de la viga soluciona de manera fácil y práctica el apoyo de los tableros y sus desmontaje para la recuperación parcial del encofrado.Through the provision that has been explained, enables the construction of the beams to support boards of formwork with great simplicity and economy, while great mechanical strength. The assembly is very simple when the terminal projection of a beam in the groove presenting the end conjugate of the following beam and this allows easy assembly and disassembly Similarly the tilt structure and nerves of sides of the constituent tubular element of the beam solve of easy and practical way the support of the boards and their disassembly for partial formwork recovery.
