Description
Portavigas para extremos de estructuras de encofrado para forjados de piso.Beams for ends of structures formwork for floor slabs.
La presente invención está destinada a dar a conocer un portavigas para extremos de estructuras de encofrado de pisos mediante el cual se consiguen sensibles ventajas con respecto a lo actualmente conocido.The present invention is intended to give know a beam carrier for ends of formwork structures of floors through which sensitive advantages are achieved with respect to to what is currently known.
Los portavigas, llamados también portacorreas, están destinados a recibir las vigas o correas dispuestas transversalmente para constituir en conjunto una estructura de soporte de tableros para encofrados de piso. Uno de los problemas con los que se encuentran los constructores en la utilización de dicho tipo de portavigas es el de la falta de correspondencia de la longitud a cubrir con los tableros de piso, con respecto a la longitud individual de estos, es decir, solo en algunos casos la longitud total del vano a cubrir coincide con un múltiplo de la longitud de los tableros, que es habitualmente de unos 2 metros. Cuando se tienen que resolver estas situaciones en la construcción, se tiene que recurrir a suplementos realizados en la propia obra en condiciones poco favorables desde el punto de vista técnico, económico y de seguridad, puesto que la realización de elementos no estándar representa en muchos casos un aumento de costes y peores características técnicas.The carrier, also called belt carrier, are intended to receive beams or straps arranged transversely to together constitute a structure of board support for floor formwork. One of the problems with which builders meet in the use of said type of beams is that of the lack of correspondence of the length to cover with floorboards, with respect to the individual length of these, that is, only in some cases the total length of the span to cover coincides with a multiple of the length of the boards, which is usually about 2 meters. When these construction situations have to be resolved, you have to resort to supplements made in the work itself in unfavorable conditions from a technical point of view, economic and security, since the realization of elements does not standard represents in many cases an increase in costs and worse technical characteristics.
El portavigas objeto de la presente invención queda definido por las reivindicaciones adjuntas y está destinado a aportar sensibles mejoras en la constitución de estructuras de este tipo, es decir, en las que la longitud del vano no coincide con un múltiplo de la longitud de los tableros y, por lo tanto, no es posible utilizar un número exacto de tableros en disposición longitudinal. Para ello, el inventor ha estudiado con detenimiento la distribución de los soportes según la longitud de un portacorreas estándar en comparación con las dimensiones de los tableros de encofrado, y con respecto a las dimensiones transversales de las vigas habitualmente utilizadas, con el resultado de que con una nueva distribución de los soportes de las correas en los portacorreas, se posibilita la utilización de los tableros estándar no solamente en disposición longitudinal, tal como es habitual, sino también en disposición transversal, lo que permite conseguir estructuras de encofrado de pisos cuya longitud sea igual a un número determinado de longitudes completas de tableros más unas fracciones compuestas por uno o varios fragmentos de longitud equivalente a la anchura de los tableros normalizados. Dicha fracción debe ser correspondiente a la de la anchura de un tablero normalizado, que habitualmente es de 0,50 metros, permitiendo además la disposición entre cada dos tableros, en posición transversal, de las correas correspondientes. Ello permitirá distribuir la longitud de portacorreas equivalente a un tablero en disposición longitudinal en varios tramos para la disposición de tableros transversalmente con un tramo final de ajuste de longitud. Así, por ejemplo, en el caso de tableros normalizados con longitud de 1,97 metros, se establecerán tres tramos de 0,55 metros y un tramo de 0,37 metros, comprendiéndose entre cada dos tramos los correspondientes apoyos para las vigas o correas, cuya anchura es de 0,05 metros, en la disposición más habitual. Se comprende, no obstante, que la realización de los nuevos portacorreas se podría establecer asimismo con otras medidas de tableros normalizados y de soportes de correas, de manera que suponiendo que se designe por d_{1} y d_{2} la longitud y anchura del tablero, y por d_{3} la anchura del soporte de la viga, se deberían cumplir las relaciones siguientes:The beam carrier object of the present invention is defined by the appended claims and is intended to provide significant improvements in the constitution of structures of this type, that is, in which the length of the span does not match a multiple of the length of the boards and, therefore, is not possible to use an exact number of boards available longitudinal. For this, the inventor has studied carefully the distribution of the supports according to the length of a Standard belt carrier compared to the dimensions of the formwork boards, and with respect to dimensions of the beams commonly used, with the result of that with a new distribution of the supports of the belts on the belt carrier, the use of the standard boards not only in longitudinal arrangement, such as usual, but also in transverse arrangement, which allows to obtain floor formwork structures whose length equals a certain number of full lengths of boards plus some fractions composed of one or more fragments of length equivalent to the width of the standardized boards. Said fraction must correspond to that of the width of a normalized board, which is usually 0.50 meters, also allowing the arrangement between every two boards, in transverse position of the corresponding belts. It it will allow to distribute the length of belt carrier equivalent to a board in longitudinal arrangement in several sections for the arrangement of boards transversely with a final section of length adjustment. Thus, for example, in the case of boards normalized with a length of 1.97 meters, three will be established sections of 0.55 meters and a section of 0.37 meters, comprising between each two sections the corresponding supports for the beams or belts, whose width is 0.05 meters, in the arrangement more habitual. It is understood, however, that the realization of new belts could also be established with other measures of standardized boards and belt supports, so that assuming that d_ {1} and d_ {2} are designated the length and width of the board, and by d_ {3} the width of the support of the beam, the following relationships should be fulfilled:
d_{1}= n \ (d_{2} + d_{3}) + d_{4},d_ {1} = n \ (d_ {2} + d_ {3}) + d_ {4},
siendo n un número entero.being n a number whole.
Para el caso de tableros con proporciones similares a las anteriormente indicadas, n = 3, lo que significa que se cumpliría:In the case of boards with proportions similar to those indicated above, n = 3, which means that would be fulfilled:
d_{1}= 3 \ (d_{2} + d_{3}) + d_{4},d_ {1} = 3 \ (d_ {2} + d_ {3}) + d_ {4},
es deciris tell
d_{4}= d_{1} - 3 \ (d_{2} + d_{3})d_ {4} = d_ {1} - 3 \ (d_ {2} + d_ {3})
Para su mejor comprensión se adjuntan a título de ejemplo unos dibujos explicativos de la presente invención, simplemente a título ilustrativo y no limitativo.For your best understanding they are attached to title example explanatory drawings of the present invention, simply by way of illustration and not limitation.
