On trouve parfois des dalles peu conventionnelles dans des r\u00e9habilitations. Dans ce cas-ci, on \u00a0dispose d\u2019une dalle compos\u00e9 d\u2019une couche de compression en b\u00e9ton de 50 mm d\u2019\u00e9paisseur, en-dessous duquel on place une brique c\u00e9ramique qui s\u2019appuie sur des poutres en bois de 140 x 140 mm de coupe.<\/p>\n
Le test a \u00e9t\u00e9 r\u00e9alis\u00e9 selon r\u00e8gle UNE EN 1365-2<\/strong>. Des thermocouples on \u00e9t\u00e9 plac\u00e9s sur la couche de compression et au long des poutres en bois, afin de pouvoir d\u00e9duire les r\u00e9sultats \u00e0 d\u2019autres configurations plus favorables; \u00e0 condition que ces configurations soient en concordance avec les limitations de la r\u00e9glementation sp\u00e9cifi\u00e9.<\/p>\n
Pour de plus amples informations, dans l\u2019Annexe E du DB SI il est \u00e9tablie une m\u00e9thode de calcul qui permet de d\u00e9terminer la r\u00e9sistance des \u00e9l\u00e9ments structuraux en bois face \u00e0 l\u2019action repr\u00e9sent\u00e9e par la courbe normalis\u00e9e temps\/temp\u00e9rature. Fondamentalement, \u00a0la r\u00e9sistance au feu est d\u00e9termin\u00e9e par la taille des poutres, le niveau d\u2019exposition au feu et les charges support\u00e9es par eux-m\u00eames.<\/p>\n

Par suite des caract\u00e9ristiques particuli\u00e8res du bois, l\u2019application de Tecwool\u00ae<\/sup> F<\/strong> dans cette solution diff\u00e8re ponctuellement par rapport au reste des parements analys\u00e9s. L\u2019hygroscopicit\u00e9 du bois fait qu\u2019il absorbe ou c\u00e8de de l\u2019eau du milieu ambiant.<\/p>\n
Afin d\u2019\u00e9viter des probl\u00e8mes d\u2019adh\u00e9rence par les contractions que souffre le bois, sa surface est recouverte avec un filet m\u00e9tallique fix\u00e9e avec d\u2019agrafes ou quelque chose de similaire au support, avant d\u2019appliquer le mortier Tecwool\u00ae<\/sup> F.<\/strong><\/p>\n
Le filet agit comme un bloc entre le produit et le parement, cela conf\u00e8re \u00e0 la solution d\u2019une\u00a0flexibilit\u00e9 extra et d\u2019une adh\u00e9rence au support ind\u00e9pendamment ses dilatations.<\/p>\n
L\u2019application sur l\u2019entrevous c\u00e9ramique est consid\u00e9r\u00e9e similaire \u00e0 celle expos\u00e9e dans de dalles et murs \u00a0en b\u00e9ton.Il est important de v\u00e9rifier qu\u2019il n\u2019y ait pas des enfoncements dans la dalle pour \u00e9viter les d\u00e9chets \u00a0du mat\u00e9riel et pour doter la projection d\u2019une finition uniforme et homog\u00e8ne.<\/p>\n
