Abstract
Description
Le présente invention concerne un procéde de construction d'élements du type poutres , chainages ou autres, à partir de tôle métallique spécialement préparée, destinée aux batiments construits a partir de maçonneries ou de béton banché. The present invention relates to a method of constructing elements of the beams, chaining or other type, from specially prepared metal sheet, intended for buildings constructed from masonry or sheet concrete.
Dans les procédés connus de ce genre , des tôles métalliques sont utilisés comme coffrage et armature des poutres et planchers réalisés au moyen de béton coulé sur ces tolets. In known processes of this kind, metal sheets are used as formwork and reinforcement of beams and floors made by means of concrete poured on these mounts.
les forces de cisaillement entre béton coulé et tôle coffrante sont reprises , soit par le frottement simple, soit par différents types de connecteurs. the shear forces between poured concrete and shuttering sheet are taken up, either by simple friction, or by different types of connectors.
Ces procédés présentent de nombreux avantages rapidité de la mise en place du coffrage , légèreté de ce coffrage , simplicité de la pose de ce coffrage. These methods have many advantages, rapidity of setting up the formwork, lightness of this formwork, simplicity of laying this formwork.
Mais ils présentent de nombreux inconvénients: coût important et surtout le traitement de la surface métalli-- que apparente est tres difficile r particulièrement pour les éléments situés a l'extérieur-des maisons
Le procédé selon l'invention permet d'éviter ces. inconvénients. La tôle décrite ci-dessus est allégée par des perforations formant des trous juducieusement répartis qui permettent la conservation de la fonction armature de 1' élément en tole , le scellement de la tôle sur le mur-support et la mise en place d'éléments minces qui peuvent grâce a ces trous etre scéllés sur la tôle .Lorsque ces éléments minces sont scellés , le coffrage est reconstitué , c'est à dire que les trous sont bouchés et le béton peut alors être coulé en place
Dans le cas ou les efforts de cisaillement entre la tale et le béton seraient importants , différents tyP- pes de connecteurs peuvent être mis en oeuvre
Les dessins annexés présentent les principales applications de ce procédé. Les figures 1 et 2 montrent une tôle coffrante perforée destinée à la construction d'une poutre Les figures 3 et 4 mettent en évidence le scellement des éléments minces inférieurs . Les figures 5 et 6 font apparaitre le scellement des éléments minces latéraux et le coulage du béton . La figure 7 montre une tôle coffrante perfor rée élaborée pour réaliser le coffrage de la joue d'une dalle de batiment .La figure 8 indique comment cette tôle est scellée sur le mur inférieur et comment sont scellés les éléments latéraux . De plus sur cette figure , on peut comprendre comment la tôle peut être réglée en hauteur et en planéité grâce a une mise au point établie par une pige spéciale " P " par rapport a un trait de niveau * T n . La figure 9 montre comment la tôle perforée sert de support à la règle N R " utilisée pour le surfaçage du béton coulé en place " B " . Les figures 11 et 12 et 13 décrivent le procédé utilisé pour l'éxécution d'un chainage de batiment sous toiture.But they have many drawbacks: high cost and above all the treatment of the apparent metallic surface is very difficult, particularly for the elements located outside the houses.
The method according to the invention makes it possible to avoid these. disadvantages. The sheet metal described above is lightened by perforations forming judiciously distributed holes which allow the conservation of the reinforcement function of the sheet metal element, the sealing of the sheet metal on the support wall and the placement of thin elements. which can thanks to these holes be sealed on the sheet. When these thin elements are sealed, the formwork is reconstituted, that is to say that the holes are plugged and the concrete can then be poured in place
In the case where the shear forces between the plate and the concrete would be significant, different types of connectors can be used
The accompanying drawings show the main applications of this process. Figures 1 and 2 show a perforated shuttering sheet for the construction of a beam Figures 3 and 4 show the sealing of the lower thin elements. Figures 5 and 6 show the sealing of the lateral thin elements and the pouring of the concrete. Figure 7 shows a perforated formwork sheet made for the formwork of the cheek of a building slab. Figure 8 shows how this sheet is sealed on the lower wall and how the side elements are sealed. In addition on this figure, one can understand how the sheet can be adjusted in height and flatness thanks to a focusing established by a special rod "P" compared to a line of level * T n. Figure 9 shows how the perforated sheet serves as a support for the NR rule "used for surfacing of poured concrete in place" B ". Figures 11 and 12 and 13 describe the process used for the execution of a building chaining under roof.
Le procédé objet de l'invention peut être utilisé pour la réalisation de tout élément de structure chainage ou poutre . Mais il s'applique surtout dans le cas où les revêtements d'imperméabilisation ou de finition doivent autre mis en oeuvre sur des supports homogAnes pour leur bon comportement dans le temps ainsi que le recommande les règles de l'art . L'élément mince scellé sur la poutre ou le chainage doit , dans ce cas , être de 4mamie nature que les éléments constituant les mures en partie courante . De cette fa çon., le comportement thermohygrométrique des supports d'enduit est homogène , ce qui évite les fissurations d'enduit souvent à la source d'infiltrations d'eau dans les maisons d'habitation The process which is the subject of the invention can be used for the production of any chaining or beam structural element. But it applies especially in the case where the waterproofing or finishing coatings must otherwise be applied on homogeneous supports for their good behavior over time as recommended by the rules of the art. The thin element sealed on the beam or the chaining must, in this case, be of the same type as the elements constituting the walls in current part. In this way, the thermohygrometric behavior of the plaster supports is homogeneous, which prevents cracking of plaster, often the source of water infiltration in residential houses.
