Abstract

The two cavities block comprises on its longitudinal walls (1) inner and outer faces rupture starters (8,9) consisting of vertical grooves. These allow the longitudinal wall on one side to be eliminated in order to constitute a lower row of open blocks and to separate the block into two parts of the same length by means of a double median partition (5). All the partitions (4,5) have in their upper part a notch (6) allowing the poured concrete to pass from one cavity to the other cavities and to the contiguous blocks.

Description

i La présente invention a pour objet un parpaingi The present invention relates to a concrete block

aggloméré creux à bancher.hollow chipboard to be laid.

Elle se rapporte d'une manière générale au domaine de la construction de murs en maçonnerie et est en particulier destinée à la réalisation de piscines, de  It relates generally to the field of construction of masonry walls and is in particular intended for the realization of swimming pools,

bassins, de fosses ou de murs de soutènement.  basins, pits or retaining walls.

Les parpaings à bancher connus sont des blocs de construction creux préfabriqués composés de deux parois latérales 1 longitudinales reliées par des cloisons transversales 2 de manière à former des alvéoles 3 traversant le parpaing de haut en bas. Les cloisons externes sont généralement disposées en retrait, constituant des demi-alvéoles avec l'extrémité des parois latérales. (figure 1). Ces blocs sont habituellement empilés en quinconce de façon à ce que les alvéoles 3 des éléments superposés se trouvent dans le prolongement les unes des autres, afin de pouvoir y loger des fers d'armature verticaux. Les cloisons 2 comportent souvent, à leur partie supérieure, des encoches 4 destinées à recevoir des fers filants horizontaux. Après assemblage d'un certain nombre de rangs de parpaings, du béton est coulé dans les alvéoles 3, ce qui a pour effets de solidariser les parpaings en formant un mur en béton armé  Known concrete blocks are prefabricated hollow building blocks composed of two longitudinal side walls 1 connected by transverse partitions 2 so as to form cells 3 passing through the block from top to bottom. The external partitions are generally set back, constituting half-cells with the end of the side walls. (figure 1). These blocks are usually stacked in staggered rows so that the cells 3 of the superimposed elements are in line with one another, so as to be able to accommodate vertical reinforcing bars therein. The partitions 2 often have, at their upper part, notches 4 intended to receive horizontal wire irons. After assembly of a certain number of blocks of concrete blocks, concrete is poured into the cells 3, which has the effect of joining the concrete blocks by forming a reinforced concrete wall

réalisé sans coffrage.made without formwork.

L'utilisation des blocs agglomérés à bancher courants pose un certain nombre de problèmes: - La réalisation de l'angle formé par deux murs se joignant à angle droit nécessite soit l'utilisation d'un coffrage local, soit de casser l'extrémité des parois 1, ce qui demande un travail  The use of agglomerated blocks with common formwork poses a certain number of problems: - The realization of the angle formed by two walls joining at right angles requires either the use of a local formwork, or to break the end of the walls 1, which requires work

important et entraîne de nombreux déchets.  important and causes a lot of waste.

- A moins de faire appel à des blocs spéciaux, le mur et le radier attenant soit ne sont pas solidarisés, soit comportent des fers d'armature communs mais sont coulés séparément, ce qui dans tous les cas présente des risques de fissures et de pertes d'étanchéité dans le cas  - Unless special blocks are used, the wall and the adjoining raft are either not joined, or have common reinforcing bars but are poured separately, which in all cases presents risks of cracks and losses sealing in case

de piscines ou de cuvelages divers.swimming pools or various casings.

- Le coulage du béton doit se faire dans chaque série verticale d'alvéoles 3, et les poteaux ainsi réalisés ne sont solidarisés que par les fers filants horizontaux qui, de surcroît, ne sont pas entièrement enrobés au droit des cloisons 2, ce qui risque d'entraîner  - The concrete must be poured in each vertical series of cells 3, and the posts thus produced are only joined together by the horizontal wire bars which, moreover, are not entirely coated in line with the partitions 2, which risks to train

des dégradations dans le temps.degradations over time.

- Les murs courbes réalisés avec ces blocs présente des méplats importants qu'il faut ensuite  - The curved walls made with these blocks have large flat areas which must then be

compenser par de fortes épaisseurs d'enduit.  compensate by thick coatings.

Le dispositif selon la présente invention supprime tous ces inconvénients. En effet, il permet de couler en une seule opération un mur et le radier attenant, de faciliter la réalisation de parois courbes et d'angles jonction de murs perpendiculaires, tout en assurant une construction homogène dont tous les éléments  The device according to the present invention eliminates all these drawbacks. In fact, it allows a wall to be poured in a single operation and the adjacent foundation raft, to facilitate the production of curved walls and angles joining perpendicular walls, while ensuring a homogeneous construction of which all the elements

sont parfaitement solidarisés.are perfectly united.

Il est constitué d'un parpaing aggloméré à bancher à deux alvéoles comportant sur les faces internes et externes des parois longitudinales des amorces de rupture consistant en rainures verticales permettant d'une part de supprimer aisément la paroi longitudinale d'un côté pour constituer un rang inférieur de parpaings ouverts du côté du radier et, d'autre part de séparer le bloc en deux parties de même longueur grâce à une cloison médiane double, toutes les cloisons présentant à leur partie supérieurs une découpe permettant au béton coulé de passer d'une alvéole aux alvéoles et aux parpaings contigus. Sur les dessins annexés, donnés à titre d'exemple non limitatif d'une des formes de réalisation de l'objet de l'invention: la figure 1, déjà citée, représente en perspective cavalière un bloc aggloméré de type courant, la figure 2 représente à une échelle différente un parpaing selon l'invention, la figure 3 montre ce parpaing vu de dessus, la figure 4 est une coupe transversale suivant les flèches F-F de la figure 3, la figure 5 représente à échelle réduite, vu de dessus, un parpaing dont l'une des parois longitudinales a été supprimée et la figure 6 montre dans les mêmes conditions  It consists of an agglomerated concrete block with two cells comprising on the internal and external faces of the longitudinal walls of the breaking points consisting of vertical grooves allowing on the one hand to easily remove the longitudinal wall on one side to constitute a row lower of breeze blocks open on the raft side and, on the other hand to separate the block into two parts of the same length thanks to a double median partition, all the partitions having at their upper part a cutout allowing the poured concrete to pass from a alveolus with contiguous alveoli and concrete blocks. In the accompanying drawings, given by way of nonlimiting example of one of the embodiments of the object of the invention: FIG. 1, already cited, shows in perspective a blockboard block of common type, FIG. 2 represents on a different scale a concrete block according to the invention, FIG. 3 shows this concrete block seen from above, FIG. 4 is a cross-section along the arrows FF of FIG. 3, FIG. 5 represents on a reduced scale, seen from above, a concrete block from which one of the longitudinal walls has been removed and Figure 6 shows in the same conditions

deux parpaings séparés en deux pour former un mur courbe.  two breeze blocks separated in half to form a curved wall.

Le dispositif, figures 2 à 6, est constitué de deux parois longitudinales 1 verticales reliées par deux cloisons transversales d'extrémité 4 et par une cloison double 5 médiane séparant deux alvéoles 3 ouvertes  The device, FIGS. 2 to 6, consists of two vertical longitudinal walls 1 connected by two transverse end partitions 4 and by a double middle partition 5 separating two open cells 3

en haut et en bas.up and down.

Le bord supérieur des cloisons 4, 5 est pourvu d'encoches 6 de guidage des fers d'armature filants horizontaux, et est abaissé de manière à former une découpe 7 en forme de trapèze destinée à permettre au béton de s'écouler latéralement vers les alvéoles 3  The upper edge of the partitions 4, 5 is provided with notches 6 for guiding the horizontal wire reinforcement bars, and is lowered so as to form a cutout 7 in the shape of a trapezoid intended to allow the concrete to flow laterally towards the alveoli 3

voisines et les parpaings contigus.neighboring and adjacent blocks.

Les parois longitudinales 1 comportent sur leur faces internes et externes des rainures en V constituant des amorces de rupture centrales 8 disposées entre les deux éléments de la cloison médiane 5, de manière à pouvoir séparer le bloc en deux parties égales fermées de longueur réduite destinées en particulier à réaliser des murs courbes. Des rainures de même type sont prévues sur les deux faces de l'une des parois longitudinales 1, situées à proximité des cloisons d'extrémité 4 et de la cloison médiane 5 de façon à former des amorces de ruptures latérales 9 permettant de supprimer aisément et proprement la moitié ou la totalité  The longitudinal walls 1 have on their internal and external faces V-shaped grooves constituting central fracture initiators 8 disposed between the two elements of the central partition 5, so as to be able to separate the block into two equal closed parts of reduced length intended for particular to realize curved walls. Grooves of the same type are provided on the two faces of one of the longitudinal walls 1, located near the end partitions 4 and the central partition 5 so as to form primers for lateral breaks 9 making it possible to easily remove and properly half or all

d'une paroi 1, afin d'obtenir des blocs ouverts d'un côté.  of a wall 1, in order to obtain blocks open on one side.

Ces blocs sont destinés à constituer le rang inférieur d'un mur attenant à un radier et permettent de disposer des fers de liaison en L appartenant au mur et au radier, ainsi que de couler ces deux éléments en une seule opération. Afin de faciliter l'alignement des parpaings, les cloisons d'extrémité 4 comportent, près de leurs bords latéraux, des nervures en saillie 10, il verticales. Elles comportent toutes deux un flanc parallèle aux faces des parois longitudinales 1 et un flanc opposé incliné par rapport au premier, les sections des deux nervures situées sur une même cloison d'extrémité étant identiques et superposables. La nervure 11 dont le flanc incliné est dirigé vers l'extérieur est située légèrement en retrait de la face externe de la paroi longitudinale 1 de façon à ce que les flancs inclinés des nervures de deux parpaings contigus soient jointifs lorsque les parpaings sont parfaitement alignés. La disposition des nervures est déterminée de manière à pouvoir présenter indifféremment  These blocks are intended to constitute the lower row of a wall adjoining a slab and allow to have L-shaped link irons belonging to the wall and the slab, as well as to sink these two elements in a single operation. In order to facilitate the alignment of the concrete blocks, the end partitions 4 have, near their lateral edges, projecting ribs 10, it vertical. They both have a sidewall parallel to the faces of the longitudinal walls 1 and an opposite side inclined relative to the first, the sections of the two ribs located on the same end partition being identical and stackable. The rib 11, the inclined flank of which is directed outwards, is situated slightly set back from the external face of the longitudinal wall 1 so that the inclined flanks of the ribs of two contiguous concrete blocks are joined when the concrete blocks are perfectly aligned. The arrangement of the ribs is determined so as to be able to present indifferently

un bloc dans un sens ou dans l'autre.  a block one way or the other.

Le positionnement des divers éléments constitutifs donne à l'objet de l'invention un maximum d'effets utiles qui n'avaient pas été, à ce jour, obtenus  The positioning of the various constituent elements gives the object of the invention a maximum of useful effects which had not, to date, been obtained.
