Abstract

The various types of building blocks constituting the system are moulded in one piece in the conventional block machines after introducing the insulating material (b) previously shaped in the specially designed mould before introduction and vibration of the concrete. The insulating material is arranged on the outer side and passes in front of the framework members such as flags, posts, lintels ... Galvanised clips pass through the insulating material and ensure that the outer protective parts (c) and inner bearing parts (a) of the building blocks are fastened together. The latter are mounted while dry and positioned using plastic embedded mounting guides. They are then secured by concrete cast in reserved cells on the inner side, some of which can be reinforced depending on static requirements.

Description

La présente invention concerne des éléments de construction de petite dimension permettant le montage en une seule opération de parois extérieures de constructions diverses répondant notamment aux normes d'isolation thermique prescrites par l'E.D.F. Ces éléments peuvent être utilisés pour la construction de murs pignon et de façade enterrés ou en élévation de tous immeubles, par exemple : pavillons d'habitation à simple RDC ou avec étages, blocs d'habitation à plusieurs niveaux, bâtiments industriels, équipements so- cio-culturels (groupes scolaires, gymnases...)The present invention relates to small building elements allowing the mounting in a single operation of external walls of various constructions meeting in particular the thermal insulation standards prescribed by the D.E.F. These elements can be used for the construction of gable walls and buried facades or elevations of all buildings, for example: single-storey or multi-storey residential pavilions, multi-storey residential blocks, industrial buildings, bio-cultural (school groups, gymnasiums ...)

Les divers éléments formant le système comprennent de l'intérieur vers l'extérieur :

  • a) la partie porteuse constituée par du béton moulé fortement alvéolé
  • b) la partie isolante constituée par une matière rigide, isolante, à pores fermées donc étanche à l'eau et à la vapeur d'eau, classement au feu M 0 (par ex. : MOUSSE DE POLYURETHANE)
  • c) la partie protection extérieure de l'isolant constituée par une dallette pleine de béton formant support de l'enduit extérieur.
The various elements forming the system include from the inside to the outside:
  • a) the load-bearing part consisting of highly cellular molded concrete
  • b) the insulating part constituted by a rigid, insulating material, with closed pores therefore impervious to water and water vapor, fire classification M 0 (for example: POLYURETHANE FOAM)
  • c) the external protection part of the insulation consisting of a slab full of concrete forming a support for the external coating.

L'ensemble est monobloc, la partie isolante formant liaison rigide entre a) et c). Cette liaison est assurée par adhérence du béton et est amélioré par un accrochage mécanique constitué par des queues d'aronde taillées dans l'isolant. Elle est renforcée par des broches métalliques en fils galvanisés de très faible section ne causant que très peu de pertes thermiques traversant l'isolant de part en part en ancrées dans les parois béton a) et c). La technique actuelle consiste à compléter l'isolation thermique insuffisante des parois porteuses en agglomérés de ciment ou béton banché par la mise en oeuvre soit d'un isolant thermique (par exemple laine de verre ou de roche, panneaux de polystyrène expansé ou de mousse de polyurétha- ne) complété par une contre cloison (aggloméré ciment ou brique terre cuite) recevant un enduit intérieur de finition (par exemple plâtre ou peinture garnissante), soit par des plaques associant ces deux éléments (par exemple : PREGYPAN).The assembly is in one piece, the insulating part forming a rigid connection between a) and c). This connection is ensured by the adhesion of the concrete and is improved by a mechanical attachment consisting of dovetails cut in the insulation. It is reinforced by metal pins in galvanized wires of very small section causing only very little heat loss passing through the insulation right through anchored in the concrete walls a) and c). The current technique consists in supplementing the insufficient thermal insulation of the load-bearing walls in agglomerates of cement or shuttered concrete by the use of either a thermal insulator (for example wool of glass or rock, panels of expanded polystyrene or foam of polyurethane) supplemented by a counter partition (agglomerated cement or terracotta brick) receiving an interior finishing coating (for example plaster or garnishing paint), or by plates combining these two elements (for example: PREGYPAN).

En mettant en oeuvre tous ces éléments en une seule fois, on fera de fortes économies de main-d'oeuvre en diminuant le temps d'exécution sur chantier, toute l'opération étant de plus exécutée par une seule entreprise. La disposition de l'isolant en avant (côté extérieur) de la partie porteuse permet de supprimer tous les ponts thermiques au niveau des ossatures BA traditionnelles (abouts de dalle, poteaux incorporés, meneaux, linteaux, feuillures) et aussi d'éviter tout dégagement de vapeurs nocives ou toxiques en cas d'élévation de température dûe à des courts-circuits d'origine électrique ou à des débuts d'incendie. Par rapport à une conception traditionnelle des murs extérieurs telle que décrite ci-avant, il est d'autre part possible de gagner de la place du fait de la diminution de l'épaisseur totale de 5 cm au moins.By implementing all these elements in one go, we will save a lot of manpower by reducing the execution time on site, the whole operation being also executed by a single company. The provision of the insulation in front (external side) of the load-bearing part makes it possible to remove all the thermal bridges at the level of the traditional BA frameworks (slab ends, incorporated posts, mullions, lintels, rebates) and also to avoid any clearance noxious or toxic vapors in the event of a rise in temperature due to short circuits of electrical origin or to the start of fire. Compared to a traditional design of exterior walls as described above, it is also possible to save space due to the reduction in the total thickness of at least 5 cm.

Le système est représenté sur les figures 1 à 12 des planches 1 à VII ci-jointes.The system is shown in Figures 1 to 12 of the attached plates 1 to VII.

  • - les figures 1 à 4 montrent la disposition générale des . éléments de murs en distinguant les parties dont les fonctions sont :
    • a) porteuse
    • b) isolante
    • c) protection extérieure de l'isolant
  • - les éléments courants de construction des murs ont une longueur théorique de 60 cm ce qui est conforme à la norme standard européenne de 30 cm (voir fig. 1-3-4)
  • - la figure 8 indique une hauteur théorique de ces éléments de 20 cm, ce qui permet de n'avoir à mettre en oeuvre que 8,33 éléments au m2 au lieu de 10 (éléments 50 X 20) ou 12,5 (éléments 20 X 40).
  • - les éléments courants possèdent un axe de symétrie permettant soit de faire des
    Figure imgb0001
     éléments de 30 cm de longueur soit de combiner entre eux des
    Figure imgb0002
     éléments à fonction différente. Ainsi la partie gauche de la figure 1 représente un ! agglo normal (N) alors que la partie droite représente un ! élément de feuillure (F). La figure 3 représente un élément d'angle saillant extérieur (S) associé à un élément normal (N). La figure 4 représente un élément d'angle rentrant intérieur (R) associé à un élément feuillure (F).
  • - la figure 2 représente des éléments permettant de construire des meneaux isolés(M).
  • - la conception particulière et nouvelle des éléments, en particulier les faces inférieures et supérieures rectifiées permet de les disposer dessus-dessous, ce qui diminue le nombre de modèles différents qu'il est d'autre part possible de fabriquer à partir des mêmes moules par simple modification des caches.
  • - de par la nouvelle conception du système, les éléments courants pèsent moins de 25 kg pièce ; affaiblissement phonique = 49 décibels aux fréquences moyennes.
  • - les éléments de chainage (C) au droit des planchers (f) (voir fig. 8) sont obtenus à partir des éléments courants par diminution de leur hauteur pour adapter celle-ci à l'épaisseur (X) de ce plancher, et d'une découpe suivant ligne (d) des figures 1 à 4 permettant la mise en place des armatures chainantes (g) du plancher. Avant bétonnage les alvéoles (a) autres que porteuses sont obturées (i)
  • - sous repère (e) sont figurées dans les figures 1 à 4 l'emplacement d'échancrures de 30 mm de longueur (vcir fig. 8) et 5 mm de profondeur (voir for. 7 pratiquées seulement du côté supérieur lors de la fabrication des éléments pour y loger des guides de montage (h) en matière plastique abandonnés dans la construction (voir fig.7)
  • - ces guides de montage (h) de forme spéciale permettent d'assurer une bonne superposition des divers éléments dans le sens de la longueur du mur ; ils tiennent compte des dépuilles de démoulage (jj des alvéoles de la partie porteuse (a)
  • - la fig. 6 montre la disposition de ces guides avec des éléments notamment d'angle disposés dessus dessous.
  • - par simple découpage à la scie à disque d'éléments standards, il est possible de s'adapter à une dimension extérieure hors trame
  • - grâce à leurs faces rectifiées, les éléments sont montés à sec, le montage parfait des diverses assises étant garanti par les guides de montage (h). La solidarisation des divers éléments est assurée par le remplissage en mortier d'une alvéole 8 X 16 sur deux (e = 0,60 m) assurant une capacité portante de 6 T au ml de mur avec un mortier de résistance 30 bars (voir détail (k) fig. 9)
  • - suivant nécessités statiques, les autres alvéoles peuvent servir de coffrage perdu à des poteaux BA pouvant reprendre des efforts verticaux ou latéraux produits par exemple par la poussée des terres, en particulier pour des raisons de construction les alvéoles correspondant aux éléments de meneau (M) et feuillure (F) seront obligatoirement bétonnées (détail (1) fig. 9). Une alvéole 16 X 18 bétonnée à une capacité portante de 18 T.
  • - les alvéoles non utilisées pour des raisons statiques peuvent servir à (voir fig. 9)
    • détail (m) : gaine de ventilation
    • détail (n) : gaine pour canalisations de chutes diverses à l'abri du gel
    • détail (o) : harpes pour liaisonnement avec cloisons ou refends intérieurs même porteurs

    les canalisations électriques même horizontales (puisque ne coupant pas les éléments porteurs) peuvent être incorporées sans problème.
  • - les 8 cm d'épaisseur d'isolant en mousse de POLYURETHANE donnent un coefficient d'isolation thermique K d'environ 0,400 W/m2/°C ; la figure 5 donne le détail des dimensions des queues d'aronde améliorant la liaison isolant- béton.
  • - la figure 5 donne également le dét.ail des broches en fil galvanisé N° 14 (φ2,2 mm) garantissant la bonne tenue de l'élément de protection extérieur(C).
  • - lors de la fabrication, l'isolant est laissé légèrement débordant du nu des parois en béton ce qui assure une étanchéité entre les éléments par mise en compression de l'isolant lors de la mise en place de ceux-ci.
  • - des goulettes formant vides de décompression sont taillées dans la face avant de l'isolant (voir fig. 1 à 4) ; un évent disposé en partie basse assurera l'évacuation des buées produites.
  • - un jeu latéral de la dallette extérieure de protection (C) de l'isolant évite à celui-ci de ne jouer aucun rôle porteur mis à part celui de support de l'enduit extérieur, de sorte que l'isolant et les broches ne seront soumis qu'aux efforts de cisaillement produits par le seul poids (dallette + enduits) directement adhérents (voir fig. 8)
  • - les figures 10 - coupe 11 - élévation 12 - vue en dessous
    donnent le détail de linteaux préfabriqués prévus
    • (p) avec volet roulant
    • (q) sans volet roulant

s'appuyant sur des éléments (M) ou (F).
  • - Figures 1 to 4 show the general arrangement of. wall elements, distinguishing the parts whose functions are:
    • a) carrier
    • b) insulating
    • c) external insulation protection
  • - the common elements of construction of the walls have a theoretical length of 60 cm which conforms to the European standard standard of 30 cm (see fig. 1-3-4)
  • - Figure 8 indicates a theoretical height of these elements of 20 cm, which allows to have to implement only 8.33 elements per m2 instead of 10 (elements 50 X 20) or 12.5 (elements 20 X 40).
  • - current elements have an axis of symmetry allowing either to make
    Figure imgb0001
     elements of 30 cm in length either to combine them
    Figure imgb0002
     elements with different functions. Thus the left part of Figure 1 represents a! agglo normal (N) while the right side represents a! rebate element (F). FIG. 3 represents an external projecting corner element (S) associated with a normal element (N). FIG. 4 represents an internal re-entrant angle element (R) associated with a rebate element (F).
  • - Figure 2 shows elements for building isolated mullions (M).
  • - the particular and new design of the elements, in particular the rectified upper and lower faces makes it possible to arrange them above-below, which reduces the number of different models which it is on the other hand possible to manufacture from the same molds by simple modification of the caches.
  • - due to the new system design, current components weigh less than 25 kg each; sound reduction = 49 decibels at medium frequencies.
  • - the chaining elements (C) in line with the floors (f) (see fig. 8) are obtained from current elements by reducing their height to adapt it to the thickness (X) of this floor, and a cut along line (d) of Figures 1 to 4 allowing the establishment chain fittings (g) of the floor. Before concreting, the cells (a) other than load-bearing cells are closed (i)
  • - under mark (e) are shown in Figures 1 to 4 the location of notches 30 mm long (see fig. 8) and 5 mm deep (see for. 7 made only on the upper side during manufacture elements for housing plastic assembly guides (h) abandoned in the construction (see fig. 7)
  • - these specially shaped mounting guides (h) ensure good superposition of the various elements in the direction of the length of the wall; they take account of the release molds (dd of the cells of the load-bearing part (a)
  • - fig. 6 shows the arrangement of these guides with elements in particular of angle arranged above below.
  • - by simple cutting with a disc saw of standard elements, it is possible to adapt to an outside dimension outside the frame
  • - thanks to their rectified faces, the elements are mounted dry, the perfect assembly of the various seats being guaranteed by the assembly guides (h). The various elements are joined together by filling one 8 x 16 cell in two with mortar (e = 0.60 m) ensuring a bearing capacity of 6 T per ml of wall with a 30 bar resistance mortar (see detail (k) fig. 9)
  • - according to static requirements, the other cells can serve as lost formwork for BA posts that can take up vertical or lateral forces produced for example by the pushing of the earth, in particular for construction reasons the cells corresponding to the mullion elements (M) and rebate (F) must be concreted (detail (1) fig. 9). A concrete 16 X 18 cell with a bearing capacity of 18 T.
  • - the cells not used for static reasons can be used for (see fig. 9)
    • detail (m): ventilation duct
    • detail (n): sheath for various fall pipes frost-free
    • detail (o): harps for bonding with partitions or interior partitions, even carriers

    even horizontal electrical pipes (since they do not cut the load-bearing elements) can be incorporated without problem.
  • - the 8 cm thickness of POLYURETHANE foam insulation gives a thermal insulation coefficient K of around 0.400 W / m2 / ° C; FIG. 5 gives the detail of the dimensions of the dovetails improving the insulating-concrete connection.
  • - Figure 5 also gives the detail of the pins in galvanized wire N ° 14 (φ2.2 mm) ensuring the good behavior of the external protective element (C).
  • - During manufacture, the insulation is left slightly overhanging the bare concrete walls which ensures a seal between the elements by compression of the insulation during the establishment thereof.
  • - nozzles forming pressure relief voids are cut in the front face of the insulation (see fig. 1 to 4); a vent located in the lower part will evacuate the fumes produced.
  • - a lateral clearance of the external protective slab (C) of the insulation prevents the latter from playing any supporting role apart from that of supporting the external coating, so that the insulation and the pins do not will be subjected only to the shearing forces produced by the only weight (slab + plaster) directly adherent (see fig. 8)

 normal elements to form special complementary concrete blocks of the same length as normal concrete blocks. 7° - Parpaing selon l'une des revendications ci-dessus caractérisé par le fait que l'on peut à la fabrication le réduire de hauteur pour l'adapter à l'épaisseur des planchers béton armé et en supprimant environ la moitié côté intérieur de la partie porteuse (a) de réaliser des éléments spéciaux de chaînage de ces planchers.7 ° - Concrete block according to one of the above claims, characterized in that during manufacture it can be reduced in height to adapt it to the thickness of the reinforced concrete floors and by removing approximately half the interior side of the load-bearing part (a) of making special chaining elements for these floors. 8° - Parpaing suivant l'une des revendications précédentes caractérisé par le fait que les bords horizontaux de la partie (c) de protection extérieure de l'isolant (b) sont biseautés de façon à ne pas pouvoir s'appuyer sur les éléments inférieurs et introduire des efforts de cisaillement supplémentaires dans la partie isolante (b) qui ne doit reprendre que les efforts (parois (c) et enduit correspondant) qui lui sont directement appliqués. D'autre part les bords verticaux présentent à l'espacement de 30 cm des chanfreins associés à des évidements circulaires de petit diamètre permettant un écoulement des eaux de condensation pouvant se former en avant de la partie isolante (b) ainsi qu'un positionnement vertical parfait des parpaings posés à sec. Ce positionnement s'effectuera à l'aide de tiges métalliques enfilées dans les évidements circulaires ci-dessus et que l'on retirera après mise en place du mortier suivant position (9) ci-après Des drains disposés en partie inférieure assureront l'évacuation des eaux de condensation.8 ° - Concrete block according to one of the preceding claims, characterized in that the horizontal edges of the part (c) of the outer protection of the insulation (b) are bevelled so that they cannot be supported on the lower elements and introduce additional shearing forces into the insulating part (b) which must only take up the forces (walls (c) and corresponding coating) which are directly applied to it. On the other hand, the vertical edges have, at the spacing of 30 cm, chamfers associated with circular recesses of small diameter allowing a flow of condensation water which can form in front of the insulating part (b) as well as a vertical positioning. perfect for concrete blocks laid dry. This positioning will be carried out using metal rods threaded into the circular recesses above and which will be removed after placement of the mortar according to position (9) below Drains arranged in the lower part will ensure evacuation condensation water. 9° - Parpaing selon l'une des revendications ci-dessus caractérisé par le fait que les murs sont montés à sec ; les éléments étant positionnés entre eux de façon parfaite par les guidages permis par les évidements verticaux circulaires décrits en (8) ci-dessus. Le dessin nouveau des divers éléments associés au fait qu'ils n'ont pas de sens inférieur-supérieur défini, permet de les monter tête bêche en réduisant le nombre des éléments spéciaux nécessaires. La stabilité du montage est garantie par un coulage de mortier de ciment dans les petites alvéoles de 8 cm de largeur ménagées dans la partie porteuse (a) lorsque celui-ci est suffisant par exemple dans le cas de rez-de-chaussée de pavillons.9 ° - Concrete block according to one of the above claims characterized in that the walls are mounted dry; the elements being positioned together in a perfect manner by the guides allowed by the circular vertical recesses described in (8) above. The new design of the various elements associated with the fact that they do not have a defined upper-lower direction, makes it possible to mount them head to tail by reducing the number of special elements required. The stability of the assembly is guaranteed by pouring cement mortar into the small 8 cm wide cells provided in the load-bearing part (a) when this is sufficient, for example in the case of the ground floor of pavilions. 10° - Parpaing selon l'une des revendications ci-dessus caractérisé par le fait que les alvéoles de grande dimension de la partie porteuse (a) peuvent être utilisées pour : - servir de gaines de ventilation - servir de gaines pcur canalisations diverses à l'abri du gel - pratiquer des harpes pour liaisonnement avec cloisons ou refends intérieurs même porteurs - incorporer des ossatures en béton armé pouvant reprendre suivant nécessités statiques des efforts verticaux dans le cas de constructions élevées ou horizontaux provoqués par exemple par la poussée des terres agissant sur des murs enterrés de sous-sol. 10 ° - Concrete block according to one of the above claims, characterized in that the large cells of the carrier part (a) can be used for: - serve as ventilation ducts - serve as sheaths for various pipes protected from frost - practice harps for bonding with partitions or split interior even carriers - incorporate reinforced concrete frameworks that can resume vertical forces according to static needs in the case of high or horizontal constructions caused for example by the push of the earth acting on buried basement walls.
