El dispositivo objeto de la presente invención está destinado a combinar vigas de soporte de los tableros es decir, las llamadas "correas" en la terminología de este sector, con dispositivos desmontables que se asocian a dichas correas, y que son los que realmente facilitan los medios para soportar los extremos de los tableros para constituir una superficie horizontal de encofrado para pisos.The device object of the present invention It is intended to combine support beams of the boards, that is, the so-called "belts" in the terminology of this sector, with detachable devices that are associated with said belts, and that are those who really facilitate the means to support the extremes of the boards to constitute a horizontal formwork surface for floors.
Los dispositivos asociados a las correas presentan largueros que quedan adaptados a las correas desde la parte inferior de éstas últimas, quedando dichos largueros asociados interiormente por puntos de unión, y presentando un cerrojo en disposición transversal, que es susceptible de quedar fijado en un soporte que adopta forma aproximada a la de un casquillo, fijado habitualmente por soldadura en la cara inferior de la correa.The devices associated with the straps they have stringers that are adapted to the straps from the lower part of the latter, being said associated stringers internally by points of union, and presenting a bolt in transversal arrangement, which is likely to be fixed in a support that adopts an approximate shape of a bushing, fixed usually by welding on the underside of the belt.
Este conjunto de elementos, conocido de modo general, se basa habitualmente en la formación de los casquillos inferiores, para alojamiento de los cerrojos transversales a base de un fleje de acero curvado sensiblemente en forma de U, cuyos brazos presentan patillas dobladas hacia el exterior que están destinadas a su soldadura en la cara inferior de la correa. Si bien este tipo de dispositivo se ha demostrado en la práctica susceptible de una aplicación rápida en las obras, se ha observado un inconveniente que en ciertas circunstancias puede afectar seriamente a la seguridad. Efectivamente, las pestañas dispuestas en la cara inferior de la correa, y unidas a éstas mediante cordones de soldadura, pueden quedar afectadas en algunos casos de defectos en la soldadura, o averías de algún tipo en la misma, de manera que el casquillo, que recibe el esfuerzo vertical en los paneles de encofrado, puede desprenderse, pudiendo dar lugar a graves accidentes.This set of elements, so known In general, it is usually based on the formation of the bushings lower, for housing the transverse bolts based on a substantially U-shaped curved steel strip, whose arms they have bent outward pins that are intended for Welding on the underside of the belt. While this kind of device has been proven in practice susceptible to a rapid application in the works, an inconvenience has been observed that In certain circumstances it can seriously affect security. Indeed, the tabs arranged on the underside of the belt, and attached to these by welding cords, can be affected in some cases of welding defects, or breakdowns of some kind in it, so that the bushing, which get the vertical effort on the formwork panels, you can detach, and can lead to serious accidents.
Para solucionar el inconveniente mencionado, el inventor de la presente invención ha realizado múltiples pruebas, y experimentaciones consiguiendo la presente invención.To solve the aforementioned problem, the inventor of the present invention has performed multiple tests, and Experiments getting the present invention.
La presente invención se basa en la parte caracterizante de la reivindicación 1.The present invention is based on the part characterizing claim 1.
La característica esencial del encofrado objeto de la presente invención estriba en que el extremo o extremos superiores del elemento que constituye el casquillo receptor del cerrojo de los apoyos desmontables, queda introducido en el interior de la correa o viga tubular, desde el lado inferior, presentando dimensiones en planta mayores que la abertura, y se apoya en la cara interna de dicha correa, lo que impide, por lo tanto, la caída fortuita.The essential feature of the object formwork of the present invention is that the end or ends superiors of the element that constitutes the receiver bushing of the lock of the removable supports, is inserted inside of the belt or tubular beam, from the bottom side, presenting dimensions in plan greater than the opening, and rests on the face internal of said belt, thus preventing the fall fortuitous
En una realización práctica, la presente invención se caracteriza por la combinación de aberturas en la cara inferior de la correa con una estructura de los ejes que determinan los casquillos, tal que los extremos de los brazos, presentan patillas por lo menos parcialmente dirigidas hacia el exterior de la "U" combinándose por inserción en los orificios de la cara inferior de la correspondiente correa para penetrar en el interior de ésta y apoyarse, después de un ligero desplazamiento lateral en la cara interna de dicho lado inferior de la correa. En las zonas de coincidencia entre los brazos del casquillo con estructura en U o similar, y las aberturas mencionadas, se efectuará la unión solidaria mediante soldadura, con la característica esencial de que al quedar dispuestos los extremos de dichos perfiles de constitución de los casquillos en el interior del elemento tubular de la correa, no existe posibilidad de caída fortuita de dichos casquillos, y por lo tanto de los tableros, ni siquiera el elemento ocaso, de que existieran defectos en las soldaduras, o se produjeran algún tipo de averías en las mismas.In a practical embodiment, the present invention is characterized by the combination of openings in the face bottom of the belt with a structure of the axes that determine the bushings, such that the ends of the arms, have pins at least partially directed towards the outside of the "U" combined by insertion in the holes of the face bottom of the corresponding strap to penetrate inside of this and lean, after a slight lateral displacement in the inner face of said lower side of the belt. In the areas of coincidence between the arms of the cap with U-structure or similar, and the mentioned openings, the union will be made solidary by welding, with the essential characteristic that when the ends of said constitution profiles are arranged of the bushings inside the tubular belt element, there is no possibility of accidental fall of said bushings, and for so much about the boards, not even the sunset element, that there were defects in the welds, or some kind of breakdowns in them.

En la figura 1 se puede apreciar la disposición
de una viga o correa de soporte (1) que adopta estructura general
tubular de sección rectangular, en cuyo lado inferior (2) quedan
dispuestos pivotes (3), (3')... para el acoplamiento a puntales y
elementos (4), (4')... dispuestos en el mismo lado inferior (2) que
adoptan forma sensible de casquillos no circulares destinados a
recibir un cerrojo de fijación (5) de un dispositivo (6) de tipo
desmontable, destinado a acoplarse en la correa (1) mediante sus
largueros rectangulares (7) y (8) unidos mediante puentes
transversales inferiores (9) y (9'). El conjunto del soporte queda
colocado, tal como es de ver en la figura 2, en la que se observan
múltiples soportes del tipo descrito, tales como, los (6), (6'),
(6'')... acoplados a las correspondientes correas, fijados por los
respectivos cerrojos, tal como el cerrojo (5) de la figura 1. Una
serie de puntales ajustables (7), (7'), (7'')... permiten el soporte
directo de las correas (1), (1'), (1'')... y de los portacorreas es
decir, vigas situadas al nivel inferior, tales como, (10) y (10'),
que reciben las correas, dando lugar a una estructura sobre la que
se disponen los paneles de encofrado, en forma de tableros
horizontales, (12),
(12'), ... que apoyándose sobre los
diferentes soportes (6), (6'), (6'')... darán lugar a la superficie
de encofrado de piso.Figure 1 shows the arrangement of a support beam or belt (1) that adopts a general tubular structure of rectangular section, on whose lower side (2) there are arranged pivots (3), (3 ') ... for the coupling to struts and elements (4), (4 ') ... arranged on the same lower side (2) that take a sensitive form of non-circular bushings intended to receive a locking bolt (5) of a device (6) Detachable type, intended to be attached to the belt (1) by its rectangular stringers (7) and (8) connected by lower transverse bridges (9) and (9 '). The support assembly is positioned, as can be seen in Figure 2, in which multiple supports of the type described are observed, such as, the (6), (6 '), (6'') ... coupled to the corresponding belts, fixed by the respective bolts, such as the bolt (5) of figure 1. A series of adjustable struts (7), (7 '), (7'') ... allow direct support of the belts (1), (1 '), (1'') ... and of the belt carriers that is, beams located at the lower level, such as, (10) and (10'), which receive the belts, giving place to a structure on which the formwork panels are arranged, in the form of horizontal boards, (12),
(12 '), ... that leaning on the different supports (6), (6'), (6 '') ... will give rise to the floor formwork surface.
De acuerdo con la presente invención, los
casquillos (4), (4')... quedan realizados, de manera que sus
extremos superiores atraviesen una abertura del lado inferior de la
correa, para introducirse en el interior de la propia correa
descansando en la cara interna del propio lado inferior. Ello, tal
como es de apreciar en las múltiples realizaciones que se muestran a
título de ejemplo, en los dibujos que se acompañan. Así, por
ejemplo, en las figuras 4 y 5, se aprecia una correa (13) cuyo lado
inferior (14) presenta dos aberturas adyacentes entre sí, (15) y
(16), en las que pueden penetrar los extremos doblados en forma de
patillas horizontales, (16') y (17) de un puente (18), destinado a
formar el casquillo que se ha descrito en las figuras anteriores.
Preferentemente la patilla (17) tendrá mayor longitud que la patilla
(16'), a efectos de facilitar la introducción y colocación de dicho
puente. Tal como se aprecia en la figura 5, una vez introducidas las
patillas (16') y (17) en el interior de la correa (13), quedan
apoyadas sobre la cara interna del lado inferior (14), permitiendo
su fijación mediante cordones de soldadura, tales como (19) y (20).
Mediante esta disposición se puede comprender que se imposibilita la
caída de los elementos (18), aunque se produjeran defectos o averías
en las soldaduras (19) y (20) puesto que, dichos elementos (18) no
pueden caer por sí mismos con respecto a la viga o correa
(13).In accordance with the present invention, the bushings (4), (4 ') ... are made, so that their upper ends pass through an opening of the lower side of the belt, to be introduced inside the belt itself resting on the inner side of the lower side itself. This, as can be seen in the many embodiments shown by way of example, in the accompanying drawings. Thus, for example, in Figures 4 and 5, a belt (13) is shown whose lower side (14) has two openings adjacent to each other, (15) and (16), into which the bent ends can penetrate of horizontal pins, (16 ') and (17) of a bridge (18), intended to form the bushing described in the previous figures. Preferably the pin (17) will be longer than the pin (16 '), in order to facilitate the introduction and placement of said bridge. As can be seen in figure 5, once the pins (16 ') and (17) have been inserted inside the belt (13), they are supported on the inner side of the lower side (14), allowing their fixation by means of cords welding, such as (19) and (20). Through this arrangement it can be understood that the fall of the elements (18) is impossible, even if defects or failures in the welds (19) and (20) occurred since, said elements (18) cannot fall by themselves with respect to to the beam or belt
(13).
En las figuras 6 y 7 se ha mostrado una realización, en la que el puente o casquillo (21), presenta dos patillas iguales (22) y (23) que entran en una abertura única (24) de la cara inferior de una correa (25), efectuándose la unión por cordones de soldadura, de manera análoga a las figuras 4 y 5.Figures 6 and 7 show a embodiment, in which the bridge or bushing (21), has two equal pins (22) and (23) entering a single opening (24) of the underside of a belt (25), the union being made by welding cords, analogously to figures 4 and 5.
En la realización mostrada en las figuras 8 a 12, se observa que el elemento de puente o casquillo (26) presenta dobles patillas en cada extremo superior, que se han indicado con los numerales (27), (27') para uno de los lados, y (28) y (28') para el lado opuesto. El lado inferior (29) de la correa (30) presenta sendos pares de aberturas (31) y (31'), (32), (32') que permiten la introducción de las patillas procediendo después a su unión por soldadura, tal como se puede observar en la figura 12. Las patillas de uno de los lados tendrán una longitud superior a las del otro, permitiendo efectuar un montaje, tal como se aprecia en las figuras 9, 10 y 11, es decir, con la introducción por las patillas de un lado, posterior introducción de las del otro, y corrimiento longitudinal del puente (26) hasta ocupar la posición definitiva.In the embodiment shown in Figures 8 to 12, it is observed that the bridge or bushing element (26) has double pins on each upper end, which have been indicated with the numerals (27), (27 ') for one side, and (28) and (28') for the opposite side. The lower side (29) of the belt (30) has two pairs of openings (31) and (31 '), (32), (32') that allow the introduction of the pins then proceeding to its union by welding, as can be seen in figure 12. The pins on one side they will be longer than the other, allowing assembly, as shown in the figures 9, 10 and 11, that is, with the introduction by the pins of a side, subsequent introduction of the other, and shift length of the bridge (26) until it occupies the position definitive
En la figura 13 se ha mostrado una realización de elemento (33) de casquillo, que presenta sus extremos doblados en forma de patillas (34) y (35), dirigidas en el mismo sentido de esta forma, combinándose con sendas aberturas (36) y (37) las patillas se podrán apoyar sobre la cara interna del lado inferior (38) de la correa (39), para recibir finalmente los cordones de soldadura (40) y (41).An embodiment of cap element (33), which has its ends bent in pin shape (34) and (35), directed in the same direction as this way, combined with openings (36) and (37) the pins may rest on the inner side of the lower side (38) of the belt (39), to finally receive the cords of welding (40) and (41).
En la realización de la figura 14, el elemento de casquillo (42) presenta un extremo sin patilla de doblado, y el otro doblado de forma que prácticamente cierra el hueco del elemento (42), formando un lado de mayor longitud (43) cuyo extremo queda dispuesto a poca distancia del extremo del otro brazo (44). De este modo, una vez introducido dicho elemento en las aberturas del lado inferior (45) de la correa (46), es posible efectuar la unión mediante los cordones de soldadura (47), (48) y (49).In the embodiment of Figure 14, the element of bushing (42) has one end without a bending pin, and the other folded so that it practically closes the hollow of the element (42), forming a side of greater length (43) whose end is arranged a short distance from the end of the other arm (44). Of this mode, once said element has been introduced into the openings on the side lower (45) of the belt (46), it is possible to make the union by welding seams (47), (48) and (49).
En la figura 15 se habrá presentado un elemento (50) de estructura similar a la de la ejecución de la figura 14, a excepción de que el lado superior (51) es simplemente recto, y el lado inferior (52) no presenta patilla doblada, quedando dispuesto en las proximidades del lado inferior (53) de la correa (54). De este modo se puede efectuar un montaje muy simple del casquillo y soldadura, mediante dos cordones, tales como (55) y (56).In figure 15 an element will have been presented (50) of a structure similar to that of the execution of Figure 14, a except that the upper side (51) is simply straight, and the lower side (52) has no bent pin, being arranged in the vicinity of the lower side (53) of the belt (54). From this way you can make a very simple assembly of the bushing and welding, using two beads, such as (55) and (56).
En la realización de la figura 16 el elemento de casquillo (57) presenta, de forma similar a las realizaciones de las figuras 14 y 15, una estructura general de tipo trapecial, con la base inferior curvada, de manera que, la aleta (58), constituye la base superior de la forma trapecial, que queda introducida en el interior de la correa (59) presentando una corta patilla extrema (60) que queda dispuesto en la posición al extremo superior del otro lado (61) de dicho elemento (57) con una separación que corresponde aproximadamente al grosor de la chapa del lado inferior (62) de la correa (59). Dos cordones de soldadura permitirán la fijación del elemento de casquillo.In the embodiment of Figure 16 the element of bush (57) presents, similar to the embodiments of the Figures 14 and 15, a general trapecial type structure, with the curved bottom base, so that the fin (58) constitutes the upper base of the trapezoidal form, which is introduced into the inside the belt (59) presenting a short end pin (60) that is arranged in the position at the upper end of the other side (61) of said element (57) with a corresponding separation approximately to the thickness of the sheet on the lower side (62) of the belt (59). Two welding cords will allow the fixing of the cap element.
En la versión de la figura 17, el elemento de casquillo (63) presenta dos lados iguales con patillas superiores ligeramente dobladas hacia dentro (64) y (65) que quedan introducidas por sendas aberturas del lado inferior (66) de la correa (67) apoyándose sobre la cara interna de dicho lado inferior (66) y permitiendo su unión con dos cordones de soldadura.In the version of Figure 17, the element of Bushing (63) has two equal sides with upper pins slightly bent inwards (64) and (65) left introduced by two openings on the lower side (66) of the belt (67) resting on the inner face of said lower side (66) and allowing its union with two welding cords.
Todo cuanto no afecte, altere, cambie o modifique la esencia del encofrado descrito, será variable a los efectos de la presente invención.Everything that does not affect, alter, change or modify The essence of the formwork described will be variable for the purposes of The present invention.
