Abstract
The invention relates to permanent formwork elements in the form of rigid panels of polyisocyanurate (PIR) foam of different thicknesses. The insulating formwork of the invention can be used to produce a shuttered concrete wall in a single step, said wall being insulated internally and externally. This method is intended for the production of walls for dwellings, up to and including so-called 4th family dwellings (certification in France), office buildings and facilities open to the public. The formwork blocks of the invention consist mainly of panels connected by spacers which can house the metal structure of the wall. The invention provides panels of different colours, having a shape that is particularly suited to the later application of any sort of coating or finishing product. Once assembled, the panels create a structure that is equivalent to any other rigid structure and offers highly advantageous thermal, acoustic and fire endurance properties.
Description
Bloc coffrant isolant Insulating formwork block
La présente invention fait partie de la famille de celles qui concernent les blocs de coffrage Isolant, utilisés pour la construction de murs en béton banché. Elle a pour objet un tel bloc de coffrage. The present invention belongs to the family of those which concern the Insulating formwork blocks, used for the construction of walled concrete walls. It relates to such a formwork block.
Un bloc de coffrage est généralement composé par l'assemblage de deux parois sous forme de plaques isolantes et distantes l'une de l'autre. Ces plaques sont llaisonnées par une structure solide. Afin d'avoir des isolations thermiques et acoustiques répondant aux normes exigées, il est préférable d'utiliser des plaques en mousse de polylsocyanurate Mousse PIR. Cette matière sera retenue dans la suite de la description et fait partie de l'objet de l'invention. A formwork block is generally composed by the assembly of two walls in the form of insulating plates and distant from each other. These plates are leased by a solid structure. In order to have thermal and acoustic insulation that meets the required standards, it is preferable to use PIR Foam polylsocyanurate foam sheets. This material will be retained in the following description and is part of the object of the invention.
On connaît par WO 200900 7566 Al un procédé de construction d'un par coffrage en utilisant des panneaux comme coffrage perdu. Ces panneaux préformés comportant chacun des plaques maintenues écartées l'une de l'autre par des éléments de résistance métallique, le vide entre ces plaques est rempli par un matériau durcisable tel que le béton. Toute fis une par un tel coffrage nécessite une isolation supplémentaire surtout du côté de l'extérieur. WO 200900 7566 A1 discloses a method of constructing a formwork using panels as a formwork. These preformed panels each having plates held apart from each other by metal resistance elements, the vacuum between these plates is filled with a hardenable material such as concrete. Any one such formwork requires additional insulation especially on the outside.
Par ailleurs, WO 19 5000 724 Al met en évidence un procédé rationnel de coulage d'un mur totalement ou partiellement Isolé, utilisant des coffrages perdus sous forme d'éléments interconnectés qui délimitent des cavités intérieures pouvant servir à la coulée du béton et permettant le passage des barres d'armature. Pour les murs isolés, on
insère dans certaines de ces cavités du coffrage une matière Isolante. Furthermore, WO 19 5000 724 A1 shows a rational method of casting a wall totally or partially insulated, using lost forms in the form of interconnected elements which delimit internal cavities that can be used for pouring the concrete and allowing the passage of rebar. For isolated walls, inserts into some of these cavities of the formwork an insulating material.
Aussi, WO 2012 010773 Al parie d'un procédé applicable dans le domaine de la fabrication de coffrage isolant, Il est composé de deux parties intérieur et extérieure, faites de mousse isolante, la particularité est que l'épaisseur de la partie extérieure est beaucoup plus grande que celle intérieure et faite en deux parties qui se montent l'une sur l'autre. Also, WO 2012 010773 A1 bets a method applicable in the field of the manufacture of insulating formwork, It is composed of two parts inside and outside, made of insulating foam, the peculiarity is that the thickness of the outer part is much larger than the inner one and made in two parts that fit together.
Cependant, parmi les problèmes que connaissent les blocs de coffrage isolant perdus est que la structure formée par les deux éléments qui la composent doit avoir des caractéristiques mécaniques suffisantes pour supporter toutes les contraintes crées lors de la coulée du béton. Cela se caractérise par l'emploi de produits isolants onéreux. En plus, pour des raisons de conformité des caractéristiques d'isolation thermique d'une construction utilisant un tel bloc, il est souvent souhaité d'augmenter l'épaisseur de la paroi extérieure. Ceci engendre donc des coûts matières élevés, et cette différence d'épaisseur entre les parties interne et externe du bloc isolant peut donner naissance à des ponts thermiques résiduels. However, among the problems experienced by the lost insulating formwork blocks is that the structure formed by the two elements that compose it must have sufficient mechanical characteristics to withstand all the constraints created during the pouring of the concrete. This is characterized by the use of expensive insulation products. In addition, for reasons of conformity of the thermal insulation characteristics of a construction using such a block, it is often desired to increase the thickness of the outer wall. This therefore generates high material costs, and this difference in thickness between the inner and outer parts of the insulating block can give rise to residual thermal bridges.
En fait, EP 0019892 Al décrit un dispositif destiné à la réalisation de revêtements de murs de bâtiments par l'application de couche d'isolant sur la partie extérieure des murs.
In fact, EP 0019892 A1 describes a device for the realization of building wall coverings by the application of insulating layer on the outer part of the walls.
EP 0091858 Al veut remédier au problème d'isolation thermique et parle d'un dispositif qui consiste à utiliser des plaques en béton sur les quelles une couche d'Isolant vient s'appliquer. Ces dispositifs en fait aident à améliorer l'isolation mais ne résolvent pas le problème des ponts thermiques et le phénomène d'apparition d'humidité. EP 0091858 A1 wants to remedy the problem of thermal insulation and speaks of a device that consists of using concrete plates on which a layer of insulation is applied. These devices actually help to improve the insulation but do not solve the problem of thermal bridges and the phenomenon of appearance of moisture.
La présente Invention a pour but de pallier à une grande partie de ces inconvénients en proposant un bloc de coffrage isolant en mousse polyisocyanurate Mousse PIR, le dit bloc présente des caractéristiques mécaniques très Intéressantes et des capacités d'Isolation thermique et acoustique élevées. Le procédé de fabrication adopté laisse que les coûts de fabrication restent faible. The present invention aims to overcome many of these disadvantages by proposing an insulating formwork block foam polyisocyanurate foam PIR, said block has very interesting mechanical characteristics and high thermal and acoustic insulation capabilities. The adopted manufacturing process leaves manufacturing costs low.
C'est ainsi, l'Invention a pour objet un bloc de coffrage isolant en mousse polyisocyanurate Mousse PIR, composé d'une plaque intérieure reliée à une autre plaque extérieure par des entretolses de liaison et de renfort. Ce bloc de coffrage est caractérisé en ce que Thus, the invention relates to an insulating shuttering block made of polyisocyanurate foam PIR foam, consisting of an inner plate connected to another outer plate by connecting and reinforcing braces.

L'invention a pour objet un bloc de coffrage isolant en mousse polylsocyanurate Mousse PIR formé des panneaux 1 et 2 constituant simultanément les parois intérieure et extérieure, reliés entre eux par des moyens de liaison et de renfort 6. The subject of the invention is an insulating shuttering block made of PIR Foam polylsocyanurate foam formed of panels 1 and 2 simultaneously constituting the inner and outer walls, interconnected by connecting and reinforcing means 6.
Afin de réaliser un coffrage, le premier panneau 1 est relié au deuxième panneau 2 via des entretoises de liaison 6. Les éléments 1 et 2 s'empilent les uns sur les autres et s'emboîtent par les points 3 et forment ainsi un tunnel qui sera le logement du béton à couler. In order to form a formwork, the first panel 1 is connected to the second panel 2 via connecting struts 6. The elements 1 and 2 are stacked on each other and fit together by the points 3 and thus form a tunnel which will be housing the concrete to sink.
Selon l'invention aussi, la forme des éléments 6 permet une liaison forte et stable des éléments 1 et 2 et ceci est parfaitement réalisé grâce à la forme des rainures 5 et à la particularité de chaque élément 6 utilisé. According to the invention also, the shape of the elements 6 allows a strong and stable connection of the elements 1 and 2 and this is perfectly achieved thanks to the shape of the grooves 5 and the particularity of each element 6 used.
Selon une caractéristique principale de la matière polylsocyanurate mousse avec laquelle les éléments 1 et 2 sont fabriqués, l'épaisseur de l'élément 2 n'est pas aussi grande que celle utilisée par l'autre forme de mousses. According to one main feature of the foam polylsocyanurate material with which the elements 1 and 2 are made, the thickness of the element 2 is not as great as that used by the other form of foams.
Un autre avantage selon une caractéristique de l'invention, les éléments 1 et 2 se
posent sur des panneaux similaires à faible hauteur et portent aussi une fois empilés les uns sur les autres les éléments de dalle grâce à la forme des tetons 3 . Another advantage according to a characteristic of the invention, elements 1 and 2 pose on similar panels at low height and also bear when stacked one on top of the slab elements thanks to the shape of the teats 3.
Selon une autre caractéristique de l'invention, la construction de murs d'habitation de la 4iéme famille comprise, des bâtiments de bureaux et établissements recevant du public sont du domaine d'utilisation de ces coffrages. According to another characteristic of the invention, the construction of residential walls 4 ith family understood, office buildings and public buildings are the field of use of these forms.
