Definitions

  • BEAM OR GIRDER FOR BUILDING CONSTRUCTION AND A BUILDING UNIT INCLUDING SAID BEAM OR GIRDER, AND A METHOD OF MANUFACTURING THE BEAM OR GIRDER.
  • the present invention relates to a beam or girder for building construction and of the kind mentioned in the introductory part of claim 1.
  • Such beams of steel, aluminium or plastic are known from the building industry, and a drawback by said known beams are, e.g. by use as horizontal supporting longitudinal girders, that a considerable part of their wall thickness is involved in carrying the weight of the girders themselves in order to keep the deflexion of the girders below a given value at a given span.
  • a light building element constructed by structural elements or structural members in which roofing plates and channel configurated base members form an integrated unit, such as for roofing elements each consisting of at least one open base profile glued directly onto an upper covering plate forming the covering as well as the loading absorber, and whereby the covering plate is wider than the base profile and along both the longitudi ⁇ nal sides thereof extends outside the base profile.
  • each covering plate has a freely protruding, unsupported side part getting a certain deflexion by loading of the covering plate. Said deflexion exposes the joint between neighbouring covering plates to great material loads and renders it practically impossible in and below the joint to obtain reasonable diffusion resistance with known means.
  • a beam or girder according to the invention, said beam being characteristic by the items set forth in the characterizing clause of claim 1.
  • a light beam construction with a high supporting ability by use as horizontal or inclined girder in relation to the weight of the beam itself.
  • each beam per se is a finished unit, they might by simple means and before their mounting on a roofing or floor construction plate for forming a building element be provided with a predetermined curvature in their longitudinal directon, so that the roof or the floor in mounted and loaded condition e.g. becomes totally planar.
  • the beam of this invention has no protruding side edges for the covering plate
  • the beam may be arranged at the outer plate side edges of the building element to be reinforced by means of beams of this invention, whereby the deflexion of said side edges become as small as possible during loading, and consequently a lasting diffusion resistance in the joining between two neighbouring building elements is achieved and secured by common tightening means.
  • the rigid edge joining thereby achieved between neighbouring building elements becomes able to transfer high bending moments, and the supporting ability of the building elements locally in the joinings or at the longitudinal edges becomes high.
  • a material which is mainly suitable for compres- sive loadings is to be understood a material being better suited for compressive loads than for tensile loads.
  • a material mainly suitable for tensile loadings is to be understood a material being better suited for absorbing tensile loads than compres ⁇ sive loads.
  • An embodiment of a beam according to claim 2 may preferably have a further, mainly for compressive loads suitable plate being firmly secured over the total length of the beam to that part of the beam located most distant from the covering plate closing the beam.
  • a more universally applicable beam seeing that it is suitable for applications as a heavy loaded longitudinal girder, e.g. as cantilever beam, and as a column or a vertical longitudi ⁇ nal girder.
  • the present invention also relates to a building unit according to claim 4, wherein the beam according to the invention is used, and where two or more beams are arranged as longitudinal girders in the building unit, which might be a roofing element, a ceiling element, a wall element or a floor element, said building unit having two of the beams arranged at each longitudinal side edges of the building unit, where they form the longitudinal sides of the building unit.
  • the building units may absorp forces or loads in the plane of the building element and loads from the facades, more secure or safe element joints, seeing that the beams of the elements at the side edges may be secured directly to each other.
  • the elements at the joinings easily by known means be made diffusion resistant and/or may absorp extra loading from e.g.
  • Said arrangement of the beams in the elements furthermore implies that arbitrary distances or openings for staircases, lifts, skylights etc. are possible between the beams forming the strong supporting side edges of neighbouring elements.
  • relatively larger recesses in the elements themselves and between the beams can be performed at given element dimensions 1) for skylights, chimneys, roof caps etc.
  • the elements with their beams arranged at their side edges can be assembled resistant to bending moments directly at their side edges, that the elements being completely alike at both side edges, so that they can be rotated 180 degrees about an axis perpendicular to the element during the mounting, which again means that fewer element types may be necessary for a given building, particularly if the building elements of the invention have box shaped beams at their longitudinal sides, and that a greater freedom of choice is obtained during the mounting.
  • the vapour seal of the element can be hidden in the longitudinal sides of the element, so that said vapour seal cannot be damaged during transportation and mounting of the building element.
  • the invention relates to a method according to the introductory clause of claim 6 for manufac- turing a longitudinal closed beam or girder according to the invention for building purposes, and the method is charac ⁇ terized by the items set forth in the characterizing clause of said claim.
  • the method is charac ⁇ terized by the items set forth in the characterizing clause of said claim.

  • the securing means are chosen in dependence on which materials are to be assembled, and said securing means include a adhesive assembly and, for further reinforcement thereof, a screw assembly, bolt assembly, nail assembly or the like.
  • the supporting ability may be further increased by arranging bulkheads 10 inside the beam 1 with predetermined spaces as indicated in fig. 3.
  • Each bulkhead 10 is e.g. secured perpendicularly to at least three of the inner walls of the beam, e.g. on the inner sides of the sides 3, 4 and 5.
  • Fig. 3 shows a building unit or module 12 in which the beam 1 according to the invention is used, and beams 1 are arranged as longitudinal girders in the building unit 12, which may be a roof element as shown, a ceiling element, a wall element or a floor element.
  • the roof building unit shown in fig. 3 may e.g. at its upper side have a 16 mm thick waterproof plywood board 14 which is or will be covered by roofing foil or roofing felt.
  • Said plywood plate 14 is directly secured to the three shown longitudinal closed beams 1 by glueing and nails or screws, and directly below the beams 1 may be arranged a vapour seal 15, e.g. of PVC foil or of the material being known as hygrodiode, dampcourse or vapour seal.

Abstract

Poutre (1) pour la construction, présentant un profil de base (3-5), conçue pour supporter essentiellement des charges de traction, et une plaque de recouvrement (2) réalisée dans un matériau apte à supporter les charges de compression, ladite plaque présentant une rigidité dans tous les sens beaucoup plus élevée que le matériau du profil de base (3-5). Cette plaque de recouvrement (2) est raccordée directement, de manière rigide afin de transmettre les moments (résistante aux mouvements de torsion) au profil de base par un joint d'encollage, de telle sorte que la cette plaque de recouvrement (2) et le profil de base (3-5) forment entre eux un élément de soutien statique. Du fait que la plaque de recouvrement (2) a la même largeur que le profil de base (3-5), que ses deux bords longitudinaux joignent de manière affleurante ceux du profil de base et que le joint rigide entre plaque de recouvrement et profil de base comporte en outre des éléments de fixation traversant en tout ou en partie la plaque de recouvrement (2), on obtient une poutre stable, aux applications nombreuses, d'un faible poids et d'une grande résistance, dont la cambrure prédéterminée, dans le sens longitudinal, est aisée à adapter, lors de son élaboration, aux conditions d'application.
