Definitions

  • the object of the invention is a system for use in the roofs, ceilings, or floors of buildings, which consists of a elongate beam, lateral support elements and a cast component carried by it, and in which the elongate beam is formed of one or more profile plates.
  • Finnish Patent Application 875327 shows a concrete frame system, in which the beam component that is open underneath is cast beforehand and composite plates are supported on flange members formed in its lower section, and in which the totality formed by the composite plates and frame beam is cast as one, so that the construction has excellent fire protection.
  • the structures according to Figures 8, 9 and 10 both the adhesion of the interior of the beam and that between the composite beam and composite plates is not complete.
  • the intention of the invention is to achieve a more effective totality formed by an elongate beam and lateral support elements, in which the structural height in particular could be smaller than previously.
  • the principal characteristics of the invention appear in the accompanying patent claims.
  • the rods or bolts penetrating the beam bind the beam structure and the further cast component so well that the further cast components carry the compressive force in the direction of the beam over a great breadth.
  • the neutral axis rises considerably, when the height of the tension side increases proportionately.
  • the invention can also be applied when a bolt structure is used in the system to hold the various components together. If the transverse reinforcement is made sufficiently long it can also act as upper surface reinforcement. It is, however, most advantageously made separately.
  • the system shown in Figure 1 consists of an elongate beam 2 formed by one or more profiled plates and lateral support elements 1 also formed by profiled plates.
  • the elongate beam encloses an internal cast mass 11.
  • Transverse steel rods 8 extend through the beam 1 including the internal cast mass 11.
  • the lateral support elements are carried on the flanges 3 of the beam profile and a further cast component 9 is carried on the lateral support elements in the form of a continuous slab.
  • the rods 8 extend inside the further cast component 9 and act as upper surface reinforcement of the continuous slab at the support point.
  • the transverse steel rods are placed through the holes 5 made close to the upper surface 4 of the elongate beam 2.
  • the elongate beam 2 includes pre-stressing elements 6, 7, and 10.
  • transverse steel rods 8 have operational functions. In addition to their acting as upper surface reinforcement for the continuous slab at the point of support they connect the slab to the elongate beam, and thirdly they act as adhesion for the internal cast mass 11 of the elongate beam to the profiled plate of the elongate beam.
  • the profiled plate of the elongate beam is profiled as a right-angled hat profile, the lower section of which includes flange components on top of which it is possible to place the lateral support elements 1.
  • a beam with an overall height 280 mm is penetrated by steel rods 420 mm long and of 16 mm diameter.
  • the elongate beam 12 is precast and the transverse steel rods bind the concrete firmly to the beam.
  • the ready elongate beam is set in place and the lateral support elements 1 are placed on top of the flanges 15. After this casting takes place as a result of which cast component 9 forms a unified structure on top of the lateral support elements 1 and the elongate beam 2.
  • FIG. 13 shows the distribution in principle between compression and tension in a frame structure in accordance with the invention.
  • the compression surface area extends strongly to the slab sections, in which case the elongate beam itself on the tension side acts more effectively.
  • the lateral support elements 1 are in the form of cast hollow slabs 17, Figure 4. These are placed in a corresponding manner on top of the flange 15 of the elongate beam, but the cavities at their ends are opened for a distance of 50 to 100 cm. Longitudinal rods 18 are pushed in from this opening. These must then be bent downwards, which is not an optimal solution from the point of view of adhesion, but is a compromise demanded by this construction. During casting the ends of the cavities of the hollow slabs 17 are filled with concrete, after which they will withstand longitudinal compression.
  • each transverse rod or bolt can only extend to one side of the beams, but when sequential rods extend to each side in turn reinforcement on both sides is achieved in this respect.

Abstract

Le système décrit, qui est destiné à être utilisé dans les toits, les plafonds et les planchers de bâtiments formés par une poutre de raccordement (2, 12) et par une plaque de raccordement (1), se compose d'une poutre de raccordement (2), de plaques de raccordement (1) portées par la poutre, ainsi que par un composant coulé (9), la poutre de raccordement (2, 12) étant composée d'une ou de plusieurs plaques profilées. La présente invention a pour but de simplifier le renforcement du système. Selon la présente invention, la poutre de raccordement (2, 12) s'étend adjacente à la surface supérieure du composant coulé (9) et la section supérieure (4) de la poutre de raccordement (2, 12) est traversée par plusieurs longues tiges transversales (8) et/ou boulons, qui s'étendent sur une distance considérable vers l'extérieur depuis le bord supérieur de la poutre de raccordement (2, 12), de façon à servir de renforcement superficiel supérieur pour la dalle continue ou à former une partie de celle-ci au niveau du point de support.

Claims (6)

  1. Système destiné à être utilisé dans les toitures, les plafonds ou les planchers de bâtiments, comprenant une poutre allongée (2, 12) qui comprend une ou plusieurs plaques profilées enfermant une masse intérieure coulée (11), des éléments porteurs latéraux (1) portés sur chaque côté de la poutre allongée, un constituant coulé supplémentaire (9) porté par les éléments porteurs latéraux, et une pluralité de tirants ou de boulons transversaux (8) qui passent à travers les plaques profilées et la masse intérieure coulée de la poutre allongée et qui s'étendent dans le constituant coulé supplémentaire (9) pour créer une adhésion entre la poutre allongée (2, 12) et ce constituant coulé supplémentaire (9), la partie supérieure de la poutre allongée et de sa masse intérieure coulée s'étendant à proximité de la surface supérieure du constituant coulé supplémentaire (9).
  2. Système selon la revendication 1, caractérisé en ce que les tirants ou les boulons transversaux (8) s'étendent sur 20 à 100 cm au-delà des deux côtés de la poutre allongée (2, 12).
  3. Système selon la revendication 1, caractérisé en ce que les tirants ou les boulons transversaux (8) s'étendent sur 10 à 20 cm au-delà des deux côtés de la poutre allongée, et en ce que, sur la poutre allongée, il est prévu un renforcement de surface distinct (15), qui agit comme renforcement de la surface supérieure.
  4. Système selon l'une quelconque des revendications 1 à 3, caractérisé en ce que les tirants ou boulons transversaux (8) sont des tiges entièrement ou partiellement filetées à l'aide desquelles les plaques profilées et/ou les autres structures du système sont reliées les unes aux autres.
