Description
La présente invention se rapporte au domaine de la construction et en particulier à celui de la réalisation des jonctions entre des parties verticales bétonnées telles que des voiles de façade avec des parties horizontales telles que des dalles.The present invention relates to the field of construction and in particular to the realization of junctions between concrete vertical parts such as facade walls with horizontal parts such as slabs.
Plus particulièrement la présente invention se rapporte à la réalisation de réservation lors de cette jonction.More particularly, the present invention relates to the realization of reservation during this junction.
On connaît bien la problématique liée aux jonctions due à la réalisation de voile de façade avec isolation par l'intérieur avec des dalles horizontales. En effet, les structures étant continues, l'isolation intérieure est interrompue au droit de la dalle et ceci sur toute la périphérie du bâtiment. Cela pose évidemment un problème important de déperdition calorique et génère souvent la présence d'une condensation à l'intérieur du bâtiment. Ce phénomène bien connu dans le monde de la construction est généralement dénommé « pont thermique ». Des dispositifs destinés à réduire les déperditions caloriques ont été proposés et consistent en général à assurer la continuité de l'isolation thermique par l'interposition d'un élément appelé rupteur thermique se présentant sous la forme d'un élément métallique et qui permet d'assurer la continuité de l'isolation intérieure avec seulement quelques ancrages ponctuels permettant ainsi de conserver la stabilité de l'ouvrage.We know the problem related to junctions due to the realization of facade veil with insulation from the inside with horizontal slabs. Indeed, the structures being continuous, the inner insulation is interrupted to the right of the slab and this on the entire periphery of the building. This obviously poses a significant problem of heat loss and often generates the presence of condensation inside the building. This phenomenon well known in the world of construction is generally referred to as "thermal bridge". Devices to reduce heat loss have been proposed and generally consist in ensuring the continuity of the thermal insulation by the interposition of an element called thermal breaker. presenting in the form of a metal element and which ensures the continuity of the interior insulation with only a few ad hoc anchors thus allowing to maintain the stability of the structure.
Afin de poser ce rupteur thermique, il est pour l'instant obligatoire d'interrompre les phases de bétonnage. En effet, ainsi que représenté à la
