fijación de barras de cualquier tipo en elementos de madera,
hormigón, materiales pétreos o cerámicos.The main advantage provided by the invention is the
Development of a system that, by means of an element of great simplicity and low cost, makes it possible to carry out very widening point easily inside the holes. The widening significantly improves the fixing systems of bars of any type in elements of wood, concrete, stone or ceramic materials.
Description
Sistema de broca con bielas articuladas para la ejecución de ensanchamientos puntuales en el interior de taladros.Drill system with articulated connecting rods for execution of point widening inside drills
La invención se enmarca en el sector de la construcción y hace referencia al diseño de un nuevo producto que permite la ejecución de ensanchamientos puntuales en el interior de taladros realizados para el anclaje de barras de cualquier tipo.The invention is part of the sector of construction and refers to the design of a new product that allows the execution of specific widening inside drills made for anchoring bars of any type.
La fijación de barras de cualquier tipo (lisas, corrugadas, roscadas, etc.) y material (acero, madera, materiales compuestos) en elementos estructurales es una solución técnica ampliamente extendida en el mundo de la construcción.Fixing bars of any type (smooth, corrugated, threaded, etc.) and material (steel, wood, materials compounds) in structural elements is a technical solution widely spread in the world of construction.
La solución habitual corresponde a la fijación de las barras mediante adhesivos y/o morteros de diversos tipos en las perforaciones o taladros previamente realizados al efecto. Dichos taladros son de diámetro constante en toda su longitud, o bien adoptan formas troncocónicas.The usual solution corresponds to fixing of the bars by adhesives and / or mortars of various types in the perforations or drills previously made for this purpose. Said drills are of constant diameter throughout their length, or They well adopt truncated conical forms.
Las investigaciones llevadas a cabo por nuestro equipo, en el campo de los anclajes en elementos estructurales de madera, han puesto de manifiesto la posibilidad de mejorar la fijación de las barras mediante un sistema de bulbos de adhesivo realizados en el interior de los taladros. Este sistema puede ser aplicable también sobre otros materiales estructurales.The investigations carried out by our equipment, in the field of anchors in structural elements of wood, have revealed the possibility of improving the fixation of the bars by means of a system of adhesive bulbs made inside the drills. This system can be also applicable to other structural materials.
El objeto de la presente invención consiste en el diseño de una broca que permite la ejecución de los correspondientes bulbos o ensanchamientos en el interior de los taladros previos realizados en cualquier material de construcción para alojar las correspondientes barras de fijación.The object of the present invention is to the design of a drill that allows the execution of corresponding bulbs or widenings inside the previous drills made in any construction material to accommodate the corresponding fixing bars.
Este sistema presenta una ventaja fundamental en el caso de las estructuras de madera frente a otras soluciones existentes que realizan el ensanchamiento del taladro mediante sistemas expansivos, ya que no se provocan tensiones perpendiculares a la fibra de la madera en el interior de la pieza.This system has a fundamental advantage in the case of wooden structures compared to other solutions existing ones that make the broadening of the drill through expansive systems, since no perpendicular tensions are caused to the fiber of the wood inside the piece.
El objeto diseñado consiste en una broca que
incluye un sistema de cuchillas unidas entre si mediante bielas
articuladas. La forma y sección de las cuchillas puede adoptar
diversas formas; en las figuras anejas se representan dos posibles
soluciones a modo
de ejemplo.The designed object consists of a drill that includes a system of blades joined together by means of articulated connecting rods. The shape and section of the blades can take various forms; two possible solutions are represented in the attached figures
as an example
El sistema articulado permite que, mediante la presión ejercida con el extremo de la broca en el fondo del taladro ciego previamente realizado, las cuchillas y/o bielas se abran conformando, con la rotación de la broca, el ensanchamiento o bulbo interior deseado. En la figura 2 se representa un esquema del proceso de realización del ensanchamiento o bulbo.The articulated system allows, through pressure exerted with the end of the drill at the bottom of the drill previously performed blind, the blades and / or connecting rods open forming, with the rotation of the drill, the widening or bulb desired interior. A diagram of the process of realization of the widening or bulb.
La sencillez del sistema permite el diseño de múltiples combinaciones de bielas, que según su disposición y tamaño permiten conformar bulbos o ensanchamientos con formas diferentes y a distintas profundidades del taladro.The simplicity of the system allows the design of multiple combinations of connecting rods, which according to your disposition and size allow to form bulbs or widenings with shapes different and at different depths of the drill.
A modo indicativo se adjuntan algunos ejemplos de la forma que puede adoptar la broca y de su proceso de funcionamiento para la ejecución del ensanchamiento interior.Indicatively, some examples are attached in the way that the drill can take and its process of operation for the execution of the internal widening.
En la figura 1 se representa en planta (gráfico a)) y en alzado frontal y lateral (gráficos b) y c)) una posible solución geométrica para el sistema propuesto.In figure 1 it is represented in plan (graphic a)) and in front and side elevation (graphs b) and c)) a possible geometric solution for the proposed system.
En la figura 2 se representa, esquemáticamente, de forma secuencial el proceso de apertura de las cuchillas por presión del elemento sobre el fondo del taladro y la forma que adopta el ensanchamiento al final del mismo. Esta forma se representa únicamente a modo de ejemplo, ya que puede ser muy variable, en función de la forma de las cuchillas y de la configuración de las bielas.Figure 2 shows, schematically, sequentially the process of opening the blades by pressure of the element on the bottom of the hole and the shape that adopt the widening at the end of it. This form is represents only by way of example, since it can be very variable, depending on the shape of the blades and the crankset configuration
La figura 3 muestra un esquema axonométrico de la solución planteada.Figure 3 shows an axonometric scheme of The solution raised.
La broca objeto de la invención consta de un vástago principal de enlace con el elemento motriz externo y una serie de piezas de longitudes y dimensiones variables que pueden combinarse para obtener ensanchamientos de un taladro previo con formas y dimensiones diversas. La forma y material de las piezas que la componen, será en cada caso el más adecuado para producir el desbaste de la superficie del material base a modificar.The drill bit object of the invention consists of a main stem of link with the external drive element and a series of pieces of varying lengths and dimensions that can combine to obtain widenings of a previous drill with various shapes and dimensions. The shape and material of the pieces that compose it, will be in each case the most appropriate to produce the roughing the surface of the base material to be modified.
La unión de las piezas entre sí y con el vástago principal se realizará mediante elementos que permitan el giro relativo entre ellas.The union of the pieces with each other and with the stem main will be done through elements that allow the rotation relative between them.
Las piezas de las bielas pueden ser de sección plana o de sección variable proporcionando mayor superficie de corte y una mayor rigidez de las mismas.The connecting rod parts can be sectional flat or variable section providing greater surface area of cutting and greater rigidity thereof.
