Description
Dispositivo para soporte de tableros de encofrado.Device for support of boards formwork
La presente invención se refiere a un soporte desmontable para tableros para encofrados de pisos, que aporta sensibles ventajas técnicas con respecto a lo actualmente conocido.The present invention relates to a support removable for floor formwork boards, which provides sensitive technical advantages over what is currently known.
En el encofrado de forjados para pisos se utilizan en la actualidad unos conjuntos de vigas entrecruzados soportados por puntales, designándose habitualmente vigas porta correas las situadas en el nivel inferior, directamente apoyadas sobre los puntales, y vigas correas las que se apoyan sobre las primeras, y sus correspondientes puntales, recibiendo superiormente los paneles de encofrado. A efectos de permitir la recuperación parcial de los elementos de encofrado, especialmente los tableros de madera, se disponen unos soportes postizos fijados en las correas que son los que reciben directamente los extremos de los tableros de manera que, después de un fraguado parcial del hormigón del forjado, se pueden desmontar los tableros del encofrado al desmontar dichos soportes de las correas.In the formwork of floor slabs currently use crosslinked beam assemblies supported by struts, usually designated portal beams straps located on the lower level, directly supported on the struts, and beams straps those that rest on the first, and their corresponding struts, receiving superiorly formwork panels. In order to allow recovery partial formwork elements, especially the boards wooden, there are some false brackets fixed on the straps that are the ones that directly receive the ends of the boards so that, after a partial setting of the concrete from the floor, the formwork boards can be removed remove said supports from the straps.
Un inconveniente que se presenta en la actualidad con dichos soportes de las correas es que, al recibir el tablero la carga del forjado de hormigón, ésta se transmite a los pasadores de los cerrojos de sujeción de dichos soportes, por lo que se debe ejercer sobre dichos pasadores una importante fuerza en el momento de su desmontaje dificultando su recuperación junto con los tableros, y siendo fuente de averías.An inconvenience that arises in the news with these supports of the belts is that, upon receiving the board the load of the concrete slab, this is transmitted to the pins of the fastening bolts of said supports, so that an important force must be exerted on these pins the moment of its disassembly hindering its recovery along with the boards, and being a source of breakdowns.
La presente invención está destinada a solucionar dicho problema de manera que, en un soporte para correas del tipo que presenta dos largueros destinados a coincidir desde abajo en uno y otro lado de las correas, y con un pasador en disposición transversal para la fijación desmontable del soporte en la correa, se prevé que la pata más corta del pasador, que está destinada a atravesar los orificios del puente de unión de los largueros del soporte y la abrazadera de la parte inferior de la correa, presente estructura general cilíndrica con una zona de mayor diámetro en las proximidades de la base de percusión, que coincide en un orificio de diámetro correspondiente del puente de unión con los largueros del soporte, mientras que el otro extremo de dicho brazo corto queda introducido en un orificio de menor diámetro del otro brazo de dicho puente. Con esta disposición, al impulsar el pasador del cerrojo para su descarga, después de un corto recorrido, al salir la parte de mayor diámetro y el extremo de la pata de sus respectivos alojamientos, el soporte podrá descender ligeramente, separándose los tableros del encofrado y descargándose de la presión recibida del forjado, permitiendo el fácil desplazamiento de la parte restante del pasador hasta su extracción completa.The present invention is intended to solve this problem so that, in a belt holder of the type that has two stringers intended to coincide from down on either side of the straps, and with a pin on transverse arrangement for detachable fixing of the support in the belt, it is expected that the shortest leg of the pin, which is destined to cross the holes of the bridge of union of the stringers of the support and the clamp of the bottom of the belt, present cylindrical general structure with an area of larger diameter in the vicinity of the percussion base, which coincides in a hole of corresponding diameter of the bridge union with the support stringers, while the other end of said short arm is inserted into a smaller hole diameter of the other arm of said bridge. With this provision, at push the bolt pin for unloading, after a short distance, when leaving the part of greater diameter and the end from the leg of their respective housings, the support may descend slightly, separating the formwork boards and discharging from the pressure received from the floor, allowing the easy movement of the remaining part of the pin to its complete extraction.
Además, el pasador del soporte de encofrado objeto de la presente invención está destinado a su fabricación unitaria en forma de pieza fundida en una fundición especial dotada de alta resistencia y tenacidad, por ejemplo fundición maleable, lo que permite conseguir un mayor economía en la fabricación del pasador y unas características de resistencia mucho más elevadas. Además, es posible realizar las cabezas extremas del pasador en una forma apropiada para la percusión tanto de montaje como de desmontaje. Simultáneamente, los puentes de unión a los largueros del soporte están realizados en una aleación ligera extrusionada con unos orificios encasquillados y están unidos por soldadura a los largueros, realizados asimismo en aleación ligera extrusionada, con las caras superior e inferior reforzadas y las caras externas nervadas para lograr mayor resistencia.In addition, the formwork bracket pin object of the present invention is intended for its manufacture unit shaped cast iron in a special cast iron high strength and toughness, for example malleable cast iron, what which allows to achieve a greater economy in the manufacture of pin and much higher resistance characteristics. In addition, it is possible to make the extreme heads of the pin in a appropriate form for percussion of both assembly and disassembly Simultaneously, the connecting bridges to the stringers of the support are made of an extruded light alloy with some holes embedded and are joined by welding to the stringers, also made of light alloy extruded, with the upper and lower faces reinforced and the veined outer faces for greater strength.
Las cabezas de percusión del pasador son substancialmente planas y están ligeramente inclinadas hacia abajo para evitar la fuerte carga excéntrica que habitualmente se ejerce en dichas cabezas en el montaje y desmontaje, cuando tienen la estructura habitual plana que es conocida.The percussion heads of the pin are substantially flat and slightly tilted down to avoid the strong eccentric load that is usually exerted in said heads in the assembly and disassembly, when they have the usual flat structure that is known.

Tal como se representa en las figuras, el soporte objeto de la presente invención comprende los travesaños (1) y (2), destinados a recibir superiormente sendos tableros de encofrado (3) y (4), quedando incorporados a una viga correa (5) mediante un puente de unión (6), que presenta los brazos (7) y (8) unidos a los largueros (1) y (2).As depicted in the figures, the Support object of the present invention comprises the crossbars (1) and (2), destined to receive superiorly two boards of formwork (3) and (4), being incorporated into a belt beam (5) by means of a bridge of union (6), that presents the arms (7) and (8) attached to the stringers (1) and (2).
El puente (6) presenta en sus brazos sendos orificios (9) y (10) para el paso del brazo corto (11) del pasador (25) que, tal como se aprecia en la figura 2, tiene dos brazos paralelos (11) y (12) y sendas cabezas (13) y (14), la primera de ellas de unión de los brazos (11) y (12), y la segunda situada en el extremo del brazo (12). Los orificios (9) y (10) están destinados a permitir el montaje y desmontaje del pasador por percusión. Tal como se aprecia en las figuras, el brazo corto (11) está destinado a introducirse en los orificios (9) y (10), que presentan a su vez sendos casquillos (15) y (16).The bridge (6) has two separate arms holes (9) and (10) for the passage of the short arm (11) of the pin (25) which, as seen in Figure 2, has two arms parallel (11) and (12) and two heads (13) and (14), the first of they of union of the arms (11) and (12), and the second one located in the arm end (12). The holes (9) and (10) are intended for allow the assembly and disassembly of the pin by percussion. Such as seen in the figures, the short arm (11) is intended to be introduced in the holes (9) and (10), which in turn have two caps (15) and (16).
Es característico de la presente invención que el conjunto del pasador (12) quede realizado en un material de fundición especial, por ejemplo, fundición férrica de tipo nodular o de otro tipo de material que permita conseguir una elevada resistencia y tenacidad. Además, presenta como característica que, una zona (17) situada cerca de la base de unión del brazo corto (11) con la cabeza (13), presenta un diámetro mayor que dicho brazo corto, correspondiéndose con el diámetro del orificio (9) con su correspondiente casquillo (15), que resultará mayor que el orificio (10) con su correspondiente casquillo (16) para la inserción del extremo del brazo corto (11).It is characteristic of the present invention that the pin assembly (12) is made of a material of special foundry, for example, nodular type iron foundry or of another type of material that allows to achieve a high resistance and tenacity. In addition, it presents as a characteristic that, an area (17) located near the base of the short arm (11) with the head (13), it has a larger diameter than said arm short, corresponding to the diameter of the hole (9) with its corresponding bushing (15), which will be larger than the hole (10) with its corresponding bushing (16) for insertion of short arm end (11).
Mediante esta disposición y tal como se observa en las figuras 3 a 6, con el pasador introducido en posición montada, tal como se aprecia en la figura 3, el brazo corto (11) del pasador pasará por el orificio de la abrazadera (18) de la parte inferior de la correa (5), insertándose en los casquillos (15) y (16), respectivamente, por la zona de mayor diámetro (17) y por el extremo del brazo (11).Through this provision and as noted in figures 3 to 6, with the pin inserted in position mounted, as shown in figure 3, the short arm (11) of the pin will pass through the hole of the clamp (18) of the lower part of the belt (5), inserting into the bushings (15) and (16), respectively, by the area of greatest diameter (17) and by the end of the arm (11).
Para el desmontaje, tal como se aprecia en las figuras 3 a 6, la percusión sobre la cabeza (14) provocará el desplazamiento progresivo del pasador, tal como es posible apreciar en las figuras 3 y 4, hasta que al llegar a la posición de la figura 5, se despegarán los tableros (3) y (4) de la losa de hormigón del forjado (19), con lo que se podrá acabar de sacar con facilidad el pasador, tal como se observa en la figura 6, pudiendo desmontar el soporte y recuperar inmediatamente los tableros (3) y (4).For disassembly, as seen in the Figures 3 to 6, percussion on the head (14) will cause progressive displacement of the pin, as it is possible to appreciate in figures 3 and 4, until arriving at the position of the figure 5, the boards (3) and (4) of the concrete slab of the forged (19), so you can easily remove the pin, as seen in figure 6, being able to disassemble the support and immediately recover the boards (3) and (4).
Los largueros (1) y (2) del soporte quedarán realizados en un material ligero extrusionado, presentando los lados superior e inferior (20) y (21), tal como se ha representado en el larguero (2), con una mayor sección que las caras laterales, de las cuales la externa (22) presentará nervios de refuerzo, por ejemplo, los que quedan determinados por la zona intermedia algo rehundida, indicados con los numerales (23) y (24).The stringers (1) and (2) of the support will remain made of an extruded lightweight material, presenting the upper and lower sides (20) and (21), as depicted on the crossbar (2), with a larger section than the side faces, of which the external (22) will have reinforcement nerves, for example, those that are determined by the intermediate zone somewhat recessed, indicated by numerals (23) and (24).
En las figuras 13 a 16 se observan vistas con mayor detalle de un puente (6) que interrelaciona los largueros (1) y (2). Dicho puente, realizado en aleación ligera por extrusionado, presenta los brazos paralelos (7) y (8) con escalonados superiores (26) y (27) para recibir los largueros que serán unidos posteriormente por soldadura. Los orificios (9) y (10) recibirán los correspondientes casquillos (15) y (16), que no se han representado en estas figura para mayor claridad.Figures 13 to 16 show views with greater detail of a bridge (6) that interrelates the stringers (1) and (2). Said bridge, made of light alloy by extrusion, it presents the parallel arms (7) and (8) with upper steps (26) and (27) to receive the stringers that will be joined later by welding. The holes (9) and (10) will receive the corresponding bushings (15) and (16), which have not been represented in these figures for clarity.
El puente (6) presentará además en los extremos de los brazos (7) y (8) y en su parte interior zonas de entrada achaflanadas o similares (28) y (29) para favorecer el centraje del soporte en la viga correa en la que se fijará.
