RECOMENDACIONES PARA LA INSTALACIÓN DE TUBOS EN MUROS PORTANTES
Los muros portantes son elementos estructurales muy importantes en la construcción de viviendas de albañilería confinada. Al respecto, la norma E-070: Albañilería, en su Capítulo 1 denominado “Aspectos Generales”, Artículo 2.6, nos brinda una recomendación a tener en cuenta en todas nuestras obras:
"Los tubos para instalaciones secas: eléctricas, telefónicas, etc., sólo se alojarán en los muros cuando los tubos correspondientes tengan un diámetro máximo de 55 mm. En estos casos, la colocación de los tubos en los muros se hará en cavidades dejadas durante la construcción de la albañilería que luego se rellenarán con concreto, o en los alvéolos de la unidad de albañilería. En todo caso, los recorridos de las instalaciones serán siempre verticales y por ningún motivo se picará o se recortará el muro para alojarlas".
Recuerda que una de las funciones que cumplen los muros portantes es transmitir las fuerzas sísmicas y el peso de la vivienda de un piso a otro hasta llegar a la cimentación. Por eso, el diseño y la construcción de los muros portantes deben estar bien realizados, evitando cualquier transformación que los afecte negativamente (Para mayor información revisar el Boletín Nº 21, sobre Losa Aligerada Unidireccional, Figura 1; y el Boletín Nº 7, Calidad de los materiales, Figura 1).
Es frecuente ver que, cuando el casco de la vivienda ya está terminado, piquemos los muros portantes en forma horizontal, vertical o diagonalmente (Figuras 1, 2 y 3), para colocar los tubos y accesorios de las redes eléctricas, telefónicas, de agua fría o caliente.
Se debe evitar esta mala práctica constructiva porque disminuye la capacidad de resistencia de los muros.
La principal consecuencia de este peligroso hábito es que, debido a la disminución del área resistente del muro, se crea un plano horizontal de debilitamiento en este, lo que podría ocasionar su rotura (Figura 4).
La norma propone una alternativa de solución a este problema y recomienda que cuando se trate de tubos para redes secas cuyos diámetros no excedan los 55 mm: durante el asentado del ladrillo se debe dejar en los muros los espacios y canales requeridos que luego se llenarán con concreto (Figura 5). Esta alternativa es aplicable a las bajadas y subidas de los tomacorrientes e interruptores, teniendo en cuenta que la tubería horizontal no debe colocarse en los muros sino en el contrapiso.
En la siguiente edición de tu Boletín Construyendo analizaremos la recomendación de la norma para los tubos cuyos diámetros excedan los 55 mm.
Recuerda:
Si picamos, debilitamos considerablemente los muros portantes (estructura).
Los recorridos de las tuberías siempre deben ser verticales. Nunca horizontales ni inclinados.
Los tubos nunca deben ir en el interior de las columnas estructurales (Figura 6).
