Description

L'invention concerne une ossature de construction, composée de parties préfabriquées comprenant plusieurs éléments en forme de plaques en béton armé (éléments de plancher ou de toit) disposés les uns au-dessus des autres, qui sont reliés par des colonnes de support, qui présentent à leurs, extrémités une plaque de revêtement en acier, des barres ancrées dans les colonnes et faisant axialement saillie vers l'extérieur a chaque extrémité des colonnes de support, les barres saillantes étant reçues dans des profilés tubulaires, qui sont insérés aux coins des éléments, le rapport de la plus petite distance intérieure des profilés tubulaires au diamètre des barres étant compris entre 3:2 et 5:2, tandis que les barres saillantes sont placées de façon qu'à l'état monté, un coin d'un élément recouvre environ un quadrant de la tête d'une colonne, tandis que les profilés tubulaires s'étendent au moins jusqu'aux faces supérieure et inférieure des éléments.The invention relates to a building frame, consisting of prefabricated parts comprising several elements in the form of reinforced concrete plates (floor or roof elements) arranged one above the other, which are connected by support columns, which have at their ends a steel cladding plate, bars anchored in the columns and projecting axially outwards at each end of the support columns, the projecting bars being received in tubular profiles, which are inserted at the corners of the elements, the ratio of the smallest internal distance of the tubular sections to the diameter of the bars being between 3: 2 and 5: 2, while the projecting bars are placed so that in the assembled state, a corner of a element covers approximately a quadrant of the head of a column, while the tubular profiles extend at least to the upper and lower faces of the elements.

Une telle ossature de construction a été décrite dans le NL-A-78.04196, dont la priorité du 20 avril 1978 est invoquée pour la présent demande de vet européen; et a aussi été décrite dans la demande de brevet néerlandais No. 77.09570 dont la priorité a été invoquée pour le NL-A-78.04196 susmentionnée mais dont l'objet est plus vaste, la demande de brevet néerlandaise 77.09570 ayant été retirée avant publication.Such a construction framework has been described in NL-A-78.04196, the priority of April 20, 1978 is invoked for the present request for European vet; and has also been described in Dutch patent application No. 77.09570, the priority of which has been invoked for the above-mentioned NL-A-78.04196, but the subject of which is broader, the Dutch patent application 77.09570 having been withdrawn before publication.

Dans l'ossature de construction selon le NL-A-78.04196 les efforts verticaux sont transmises par moyen des barres saillantes qui' s'appuient contre des plaques d'arrêt intermédiaires, qui sectionnent les profiles tubulaires presque perpendiculairement et qui sont ancrées dans les éléments.In the construction framework according to NL-A-78.04196 the vertical forces are transmitted by means of projecting bars which 'rest against intermediate stop plates, which cut the tubular profiles almost perpendicularly and which are anchored in the elements .

Cette ossature de construction présente l'inconvénient que les barres saillantes, qui ne peuvent pas être enveloppées avec du béton sous les plaques d'arrêt, ne sont pas capables de supporter les efforts verticaux que se produisent sauf si elles ont une grande épaisseur. Vu que les profilés tubulaires doivent saisir lesdites barres en laissant un jeu considérable afin d'éliminer les tolérances présentes, la construction devient nécessairement très lourde. En outre la longueur rélative- ment grande des barres qui sortent des colonnes entraîne le risque que ces barres peuvent être cintrées pendant le transport, ce qui rendra l'installation des colonnes et des éléments difficile.This construction frame has the disadvantage that the projecting bars, which cannot be wrapped with concrete under the stop plates, are not able to withstand the vertical forces that occur unless they are of great thickness. Since the tubular profiles must grip said bars, leaving considerable play in order to eliminate the tolerances present, the construction necessarily becomes very heavy. In addition, the relatively large length of the bars emerging from the columns entails the risk that these bars may be bent during transport, which will make installation of the columns and elements difficult.

La présente invention a pour objet une ossature de construction dans laquelle toutes lesdites difficultés sont éliminées.The present invention relates to a construction frame in which all of said difficulties are eliminated.

A cet effet et conformément à l'invention, l'ossature de construction selon la présente invention est caractérisée en ce que les profilés tubulaires prévus aux coins des éléments sont disposés entre les plaques de revêtement qui présentent destions pour le passage dans barres saillantes, que lesdits profils tubulaires. transmettent les efforts verticaux, les profilés tubulaires étant constitués d'une première cornière qui forme le coin et ne dépasse pas les prolongements des bords de l'élément et d'une seconde cornière qui est soudée à la première à l'intérieur de celle-ci, de façon à former une ouverture tubulaire, tandis que les bords des éléments des barres précontraintes renforçant sont fixées à l'aide d'éléments de fixation à écrous aux ailes de la première cornière et que les espaces creux ménagés entre et dans les profilés tubulaires sont remplis au moins partiellement d'une masse durcissable.For this purpose and in accordance with the invention, the construction framework according to the present invention is characterized in that the tubular profiles provided at the corners of the elements are arranged between the covering plates which have destinies for passage in projecting bars, that said tubular profiles. transmit the vertical forces, the tubular profiles being made up of a first angle which forms the corner and does not exceed the extensions of the edges of the element and of a second angle which is welded to the first inside of it ci, so as to form a tubular opening, while the edges of the elements of the reinforcing prestressed bars are fixed with the aid of nut fastening elements to the wings of the first angle and that the hollow spaces formed between and in the profiles tubulars are at least partially filled with a curable mass.

Suivant l'invention les barres ne servent plus pour la transmission des efforts verticaux, mais servent a positionner les éléments et les colonnes les uns par rapport aux autres. Par conséquence lesdites barres saillantes peuvent être faites plus légères et beaucoup plus courtes.According to the invention, the bars are no longer used for transmitting vertical forces, but are used to position the elements and the columns with respect to each other. Consequently, said projecting bars can be made lighter and much shorter.

Les profilés tubulaires qui transmettent les efforts verticaux dans la construction selon l'invention sont ancrées dans les éléments. Gràve à la disposition des cornières, des points de fixation pour les barres précontraintes sont obtenus facilement.The tubular profiles which transmit the vertical forces in the construction according to the invention are anchored in the elements. Strikes available to the angles, fixing points for the prestressed bars are easily obtained.

Il est à hoter, que la caractéristique selon laquelle les efforts verticaux sont transmis par des profilés tubulaires et des plaques en acier prévues aux extrémités des colonnes de support est déjà connue du US-A-3 261 135, du US-A-3 783 565 et du DE-A-24 42 941 pour l'appui de poutres horizontales sur des colonnes.It should be noted that the characteristic according to which the vertical forces are transmitted by tubular profiles and steel plates provided at the ends of the support columns is already known from US-A-3,261,135, from US-A-3,783 565 and DE-A-24 42 941 for supporting horizontal beams on columns.

L'invention est illustrée en référence aux dessins ci-annexés, dans lesquels:

  • - la figure 1 est une coupe de deux colonnes et de deux éléments adjacents selon l'invention;
  • - la figure 2 est une coupe suivant la ligne B-B de la figure 1;
  • - la figure 3 est une vue en plan des détails de la réalisation d'un profilé tubulaire de coin;
  • ― la figure 4 est une vue des mêmes détails en élévation latérale.
The invention is illustrated with reference to the accompanying drawings, in which:
  • - Figure 1 is a section of two columns and two adjacent elements according to the invention;
  • - Figure 2 is a section along line BB of Figure 1;
  • - Figure 3 is a plan view of the details of the embodiment of a tubular corner profile;
  • - Figure 4 is a view of the same details in side elevation.

Selon la forme d'exécution de l'invention montrée aux figures, la colonne en béton 33 est pourvue à une extrémité d'une plaque de tête 31. La plaque de tête 31 est traversée par les barres 32a et 32b qui sont partiellement insérées dans la colonne 33. On retrouve la même disposition pour la colonne suivante 34 munie d'une plaque 35 et de barres 36a et 36b. La figure 2 montre les quatre barres 32. Au voisinage des coins des éléments 21 sont insérés des profilés de fixation tubulaires, qui sont constitués d'une cornière lourde 20 qui forme un des coins de l'élément 21 et s'étend à l'intérieur des prolongements imaginaires des bords 22 et 23 et d'une deuxième cornière 24 un peu plus légère soudée à la première comière 20 à l'intérieur de celle-ci. Les deux cornières 20 et 24 sont soudées sur une plaque de placée du côté de la face inférieure de l'élément et base carrée 25, dont la grandeur correspond approximativement à celle differentes ailes des cornières 20 de quatre éléments (21) contigus. Un trou 26 ménagé dans la plaque de base 25 correspond au cercle inscrit dans l'intervalle compris entre les deux cornières 20 et 24. Des barres d'armature latérale précontraintes 27a, 27b, 27c, 27d et 28a, 28b et 28c et ne doivent pas dépasser de plus sont fixées à l'aide d'écrous 29, à l'état précontraint, aux ailes de la cornière 20. Les barres d'armature untrées 30 et 30a, qui sont soudées aux ailes de la cornière 20 reprennent avec les barres 27 et 28 les forces extérieures horizontales. Ces deux barres peuvent former ensemble une boucle.According to the embodiment of the invention shown in the figures, the concrete column 33 is provided at one end with a head plate 31. The head plate 31 is crossed by the bars 32a and 32b which are partially inserted in column 33. The same arrangement is found for the next column 34 provided with a plate 35 and bars 36a and 36b. FIG. 2 shows the four bars 32. In the vicinity of the corners of the elements 21 are inserted tubular fixing profiles, which consist of a heavy angle 20 which forms one of the corners of the element 21 and extends to the inside imaginary extensions of edges 22 and 23 and of a second slightly lighter angle 24 welded to the first edge 20 inside thereof. The two angles 20 and 24 are welded to a plate placed on the side of the underside of the element and base. square 25, the size of which corresponds approximately to that of the different wings of the angles 20 of four contiguous elements (21). A hole 26 made in the base plate 25 corresponds to the circle inscribed in the interval between the two angles 20 and 24. Prestressed lateral reinforcing bars 27a, 27b, 27c, 27d and 28a, 28b and 28c and must not not exceed more are fixed with nuts 29, in the prestressed state, to the wings of the angle iron 20. The untreated reinforcement bars 30 and 30a, which are welded to the wings of the angle iron 20 resume with the bars 27 and 28 the horizontal external forces. These two bars can form a loop together.

Les cornières 20, 24 et les plaques de base' carrées 25 ont au moins une hauteur égale à l'épaisseur des éléments 21 reliant les cornières 20 de deux bords opposés de chaque élément de quelques millimètres la surface des éléments 21 en leurs coins. Lorsque les éléments 21 sont placés sur la tête de la colonne 33, les plaques de base carrées 25 prennent donc appui sur la plaque 31. De même, une colonne suivante 34 qui porte un élément suivant (non représenté) prend appui par la plaque 35 sur l'autre extrémité des cornières 20, 24, qui transmettent les efforts verticaux. Les tubes 37a et 37b sont utilisés pour bien centrer la colonne 34 par rapport à la colonne 33. Les tubes 37 sont enfilés sur les extrémités des barres 32a, 32b et 36a, 36b. L'intervalle entre les tubes 37 et les cornières, de même que tous les intervalles entre les éléments 21, sont remplis d'un mortier de sable et de ciment 50 ou d'un autre matériau durcissable. Les têtes des tubes 37 sont recouvertes pendant ce traitement et les tubes sont en même temps fixés l'un par rapport à l'autre. Le mortier présente une signification constructive dans la mesure où les parties montées de manière fixe l'une par rapport à l'autre ne peuvent plus glisser l'une par rapport à l'autre.The angles 20, 24 and the square base plates 25 have at least a height equal to the thickness of the elements 21 connecting the angles 20 of two opposite edges of each element by a few millimeters the surface of the elements 21 at their corners. When the elements 21 are placed on the head of the column 33, the square base plates 25 therefore bear on the plate 31. Likewise, a next column 34 which carries a following element (not shown) is supported by the plate 35 on the other end of the angles 20, 24, which transmit the vertical forces. The tubes 37a and 37b are used to properly center the column 34 relative to the column 33. The tubes 37 are threaded on the ends of the bars 32a, 32b and 36a, 36b. The interval between the tubes 37 and the angles, as well as all the intervals between the elements 21, are filled with a mortar of sand and cement 50 or other curable material. The heads of the tubes 37 are covered during this treatment and the tubes are at the same time fixed relative to each other. The mortar has a constructive meaning insofar as the parts mounted in a fixed manner with respect to one another can no longer slide one with respect to the other.

Les profilés tubulaires 20, 24 peuvent présenter sur leur côté libre (c'est-à-dire non recouvert de béton), un orifice de levage. Des orifices de levage supplémentaires ne doivent donc pas être prévus.The tubular profiles 20, 24 may have on their free side (that is to say not covered with concrete), a lifting orifice. Additional lifting holes must therefore not be provided.
