Abstract
Sistema de fijación de barras en madera mediante bulbo adhesivo. El problema técnico planteado hace referencia a la mejora de la fijación de barras de cualquier tipo y material en elementos estructurales de madera con objeto de mejorar su anclaje. La solución aportada consiste en la formación de un bulbo o ensanchamiento puntual en el interior del taladro realizado para alojar la barra. Dicho ensanchamiento se rellena posteriormente con el adhesivo conformando un bulbo que mejora el anclaje de la barra. La principal ventaja que aporta el sistema es su eficacia para transmitir la carga de la barra a la madera, lo que se traduce en la posibilidad de reducir de forma significativa la longitud precisa de taladro; ello supone una sustancial mejora de gran aplicabilidad en el sector de la construcción.Fixing system of bars in wood by means of adhesive bulb. The technical problem raised refers to the improvement of the fixation of bars of any type and material in structural wooden elements in order to improve their anchoring. The solution provided consists in the formation of a bulb or point widening inside the hole made to house the bar. Said widening is subsequently filled with the adhesive forming a bulb that improves the anchoring of the bar. The main advantage of the system is its efficiency in transmitting the load of the bar to the wood, which translates into the possibility of significantly reducing the precise length of the drill; This implies a substantial improvement of great applicability in the construction sector.
Description
Sistema de fijación de barras en madera mediante bulbo adhesivo.Fixing system of bars in wood by adhesive bulb
La invención se enmarca en el sector de la construcción y hace referencia a la mejora de la fijación de barras de cualquier tipo y material en elementos estructurales de madera con el fin de mejorar su anclaje.The invention is part of the sector of construction and refers to improved bar fixation of any type and material in wooden structural elements in order to improve your anchor.
La fijación de barras de cualquier tipo (lisas, corrugadas, roscadas, etc.) y material (acero, madera, materiales compuestos, etc.) en elementos estructurales de madera es una solución técnica ampliamente extendida en el mundo de la construcción. Su utilización comprende tanto su empleo en obras de nueva construcción como en reparaciones estructurales de construcciones ya existentes.Fixing bars of any type (smooth, corrugated, threaded, etc.) and material (steel, wood, materials compounds, etc.) in structural wood elements is a technical solution widely extended in the world of building. Its use includes both its use in works of new construction as in structural repairs of existing buildings.
La solución habitual corresponde a la fijación de las barras mediante adhesivos de muy diverso tipo en las perforaciones o taladros previamente realizados al efecto. Dichos taladros son de diámetro constante en toda su longitud. Al objeto de garantizar la necesaria capacidad mecánica de las barras, los taladros tienen que tener una longitud mínima para que la superficie de contacto sea suficiente para evitar el desprendimiento de la barra, cuando ésta se somete a los esfuerzos pertinentes. Ello supone un inconveniente claro, pues obliga a la realización de taladros de gran profundidad, en muchos casos incompatibles con las dimensiones de los elementos estructurales. En otras situaciones, la limitación en la longitud factible del taladro reduce de forma significativa la capacidad resistente de la barra anclada.The usual solution corresponds to fixing of the bars by means of adhesives of very different types in the perforations or drills previously made for this purpose. Sayings Drills are of constant diameter throughout their length. In order to guarantee the necessary mechanical capacity of the bars, the drills must have a minimum length for the contact surface is sufficient to prevent detachment of the bar, when it is subjected to the relevant efforts. This is a clear inconvenience, as it forces the realization of deep holes, in many cases incompatible with the dimensions of the structural elements. In other situations, the limitation in the feasible length of the drill reduces Significant resistant capacity of the anchored bar.
Las investigaciones llevadas a cabo por nuestro equipo han puesto de manifiesto la posibilidad de reducir la longitud precisa de taladro y mejorar eficazmente la fijación de la barra mediante el sistema cuyas características son el objeto de la presente invención.The investigations carried out by our team have revealed the possibility of reducing the Precise drill length and effectively improve the fixing of the bar through the system whose characteristics are the object of the present invention
La invención consiste en la formación de un bulbo o ensanchamiento puntual en el interior del taladro de diámetro constante realizado para alojar la barra. Dicho ensanchamiento puede realizarse en el fondo del taladro o en cualquier otra posición intermedia. Las dimensiones del ensanchamiento pueden ser cualesquiera, así como su forma, que puede definirse mediante superficies simples o complejas. Previamente a la introducción de la barra el taladro se rellena parcialmente con adhesivo adecuado a los materiales a unir, introduciéndose posteriormente la barra que se pretende fijar.The invention consists in the formation of a bulb or point widening inside the drill constant diameter made to house the bar. Saying widening can be done at the bottom of the hole or in any other intermediate position. The dimensions of widening can be any, as well as its shape, that It can be defined by simple or complex surfaces. Prior to the introduction of the bar the drill is filled partially with adhesive suitable to the materials to be joined, later introducing the bar to be fixed.
El ensanchamiento o bulbo creado relleno de adhesivo mejora de forma sustancial la eficacia para transmitir a la madera la carga aplicada a la barra, lo que se traduce en la posibilidad de reducir de forma significativa la longitud precisa de taladro.The widening or bulb created filling of Adhesive substantially improves the effectiveness to transmit to the wood the load applied to the bar, which translates into the possibility of significantly reducing the precise length of drill.
El sistema es aplicable a barras de cualquier material y tipo así como a adhesivos tanto mono como bicomponentes siempre que sean compatibles e idóneos para la unión del material de la barra con la madera.The system is applicable to bars of any material and type as well as adhesives both mono and bicomponents provided they are compatible and suitable for joining the material of the bar with the wood.
Para la mejor compresión de cuanto queda escrito en la presente memoria, se acompañan unos dibujos en los que, tan sólo a título de ejemplo, se representan dos casos prácticos de bulbo.For the best understanding of how much is written in the present report, some drawings are attached in which, so Just as an example, two practical cases of bulb.
En la figura 1 se representa una sección vertical que muestra una barra roscada encolada con adhesivo en el interior de un taladro en el que se ha practicado en su fondo un bulbo o ensanchamiento de geometría compleja.Figure 1 shows a section vertical showing a glued threaded bar with adhesive on the inside a drill in which a bottom has been practiced bulb or widening of complex geometry.
En la figura 2 se representa una sección vertical de una barra encolada con adhesivo, en la que el bulbo de forma cilíndrica se ha situado en una posición intermedia del taladro.Figure 2 shows a section vertical of a glued bar with adhesive, in which the bulb of cylindrical shape has been placed in an intermediate position of the drill.
A modo de ejemplo de realización de una fijación de una barra roscada sometida a tracción en una pieza de madera, el proceso detallado sería el siguiente:By way of example of a fixation of a threaded rod subjected to traction on a piece of wood, the Detailed process would be as follows:
Ejecución de un taladro de diámetro constante en toda su profundidad mediante el empleo de una broca del tipo berbiquí.Running a drill of constant diameter in full depth by using a drill of the type brace.
Ejecución del bulbo en el fondo del taladro incrementando el diámetro mediante el empleo de una broca de cuchilla excéntrica.Running the bulb in the bottom of the drill increasing the diameter by using a drill bit eccentric blade
Relleno parcial del taladro con adhesivo bicomponente de base epoxídica.Partial filling of the hole with adhesive Two component epoxy base.
Introducción mediante presión y rotación de la barra roscada hasta tocar el fondo del taladro.Introduction by pressure and rotation of the threaded rod until it touches the bottom of the hole.
