Abstract

Prearmed nerve for forging "in situ". The invention consists of the resulting product, of the assembly of the bars (a) of the longitudinal passive reinforcements and the lattice (b) of the transverse reinforcement, which compose a joist of a unidirectional or bidirectional floor, with two or more spacers (c) ) that guarantees the correct positioning of the reinforcements in the ribs formed between the slabs of a slab, respecting the coverings with respect to the formwork, required in the current applicable regulations, and all this done by any of the joining methods (d) allowed in the standards for reinforcing steel of linear elements.

Description

NERVIO PREARMADO PARA FORJADO IN SITU PREPARED NERVE FOR FORGED IN SITU

SECTOR DE LA TÉCNICA SECTOR OF THE TECHNIQUE

La invención se encuadra en el sector técnico de la construcción de forjados unidireccionales, más concretamente en los relativos a los sistemas de bovedillas y nervios "in situ". The invention falls within the technical sector of the construction of unidirectional slabs, more specifically in those related to vault and nerve systems "in situ".

ESTADO DE LA TÉCNICA STATE OF THE TECHNIQUE

Actualmente, en la construcción de forjados, el rendimiento para la colocación de los mismos, ha adquirido una gran importancia a la hora de optimizar costes. Por ello en los casos de forjados "in situ", donde la realización de los mismos se hace colocando elementos como bovedillas, separadores, barras de armaduras pasivas longitudinales y refuerzos transversales, el rendimiento en el montaje se ve reducido, puesto que la colocación de todos sus componentes se realiza de manera unitaria. At the moment, in the construction of floors, the performance for the placement of the same, has acquired a great importance at the time of optimizing costs. Therefore, in the case of "in situ" slabs, where the realization of these is done by placing elements such as vaults, separators, longitudinal passive reinforcement bars and transverse reinforcements, the assembly performance is reduced, since the placement of All its components are done in a unitary manner.

.EXPLlCACIÓN DE LA INVENCiÓN . EXPLANATION OF THE INVENTION

En líneas generales, el nervio prearmado para forjado "in situ", que la invención propone, es un objeto tridimensional que engloba y está compuesto de: a) la armadura pasiva longitudinal según el cálculo estructural, formada por barras de acero corrugado para la construcción; b) la armadura transversal en celosía, que confiere al nervio prearmado rigidez y estabilidad, que permite el fácil manejo a la vez que colabora en la resistencia del nervio "in situ" frente a esfuerzos cortantes; c) de los separadores, piezas auxiliares realizadas de diferentes formas y materiales, que mantienen los recubrimientos exigidos en la colocación de las armaduras de los forjados "in situ" respecto de los elementos de encofrado; d) todo ello ensamblado, mediante los tipos de uniones permitidas en la normativa vigente para armaduras de acero de elementos estructurales lineales, conforma una pieza a la que denominamos nervio prearmado. In general, the pre-assembled forging nerve "in situ", which the invention proposes, is a three-dimensional object that encompasses and is composed of: a) the longitudinal passive reinforcement according to the structural calculation, formed by corrugated steel bars for construction ; b) the transverse lattice reinforcement, which gives the prearmed nerve stiffness and stability, which allows easy handling while collaborating on the resistance of the nerve "in situ" against shear stresses; c) of the separators, auxiliary parts made of different shapes and materials, which maintain the required coatings in the placement of the reinforcement of the slabs "in situ" with respect to the formwork elements; d) all this assembled, by means of the types of joints allowed in current regulations for steel reinforcements of linear structural elements, forms a piece that we call pre-assembled nerve.

Los nervios prearmados resultan piezas de menor peso y volumen que la semivigueta prefabricada; son elementos unitarios que engloban la armadura pasiva, la armadura transversal y los separadores frente a la necesidad de la colocación individual de estos elementos en los forjados "in situ"; y gracias a ello se logra aumentar el rendimiento en la colocación de las viguetas en obra, puesto que éstos se elaboran en taller acorde con las necesidades derivadas del cálculo estructural del forjado, en unas condiciones más optimas que mejoran la productividad, además de reducir la necesidad de transporte de viguetas desde el taller a la obra, al resultar un producto final menos pesado y voluminoso. Pre-assembled nerves are pieces of less weight and volume than the prefabricated half-beam; they are unitary elements that include passive reinforcement, transverse reinforcement and spacers in the face of the need for individual placement of these elements in the "in situ" floor slabs; and thanks to this, it is possible to increase the performance in the placement of joists on site, since these are made in a workshop according to the needs derived from the structural calculation of the slab, in more optimal conditions that improve productivity, in addition to reducing the Need to transport joists from the workshop to the work, as it is a less heavy and bulky final product.

La armadura pasiva longitudinal se elabora con barras rectas o con barras en cuyos extremos se practican dobleces, que permiten salvar la armadura longitudinal de la viga o zuncho al que acometen, generalmente dispuestos de forma perpendicular, y se dispone en calidad, número, diámetro y longitud según el resultado del cálculo estructural. La armadura transversal en celosía, que se fabrica en taller o se utiliza según los diferentes tipos comerciales existentes, se dispone según la calidad, sección y distancia de paso resultantes del cálculo estructural. Los separadores, que se conforman en taller o se utilizan según los tipos comerciales existentes, se disponen en número suficiente, y nunca menor de dos unidades, para conseguir la manejabilidad del nervio prearmado resultante y asegurar los recubrimientos exigidos según el cálculo estructural. The longitudinal passive reinforcement is made with straight bars or with bars at the ends of which folds are made, which allow saving the longitudinal reinforcement of the beam or strip that they undertake, generally arranged perpendicularly, and is arranged in quality, number, diameter and length according to the result of the structural calculation. The transverse lattice reinforcement, which is manufactured in the workshop or used according to the different existing commercial types, is arranged according to the quality, section and passage distance resulting from the structural calculation. The separators, which are formed in the workshop or used according to the existing commercial types, are arranged in a sufficient number, and never less than two units, to achieve the manageability of the resulting pre-assembled nerve and ensure the required coatings according to the structural calculation.

Con la utilización de los nervios prearmados, se consiguen las siguientes ventajas en obra para el sistema de forjado que la invención preconiza: With the use of pre-assembled ribs, the following advantages are achieved on site for the slab system that the invention advocates:

• •
Facilidad y rapidez de colocación. Ease and speed of placement.

• •
Menor necesidad de utilización de los medios auxiliares de elevación. Less need to use auxiliary lifting means.

• •
Menor necesidad de utilización de medios de transporte. Less need to use means of transport.
