Definitions

  • the present invention relates to elongate structural elements which may be fitted together to form a frame which may be used in the construction of buildings, e.g. for the construction of floors, intermediate platforms and ceilings, vertical walls including external, internal and partitioning walls or portal or roof frames.
  • a structural element for erecting buildings, and also for erecting building models is described in DE 3 532 846 including a bar-type frame having a U-profile, which is open at the top, as base profile and a U-profile, which is open at the bottom, as top profile and also having posts and struts which connect base and top profiles and compromise a C-profile.
  • the base profiles and the top profiles are configured such that they can be plugged together, and fixed, in each case at their ends via plug-in connectors to form a top frame corresponding to the building outline.
  • the base profiles and the top profiles are provided in each case with a number of plug-in shoes which corresponds to the number of the posts provided, which shoes are held displaceably and fixedly on the relevant base or head profile and into which the posts are plugged by their free ends.
  • DE 806 388 describes a method to couple crossing U-profiles.
  • tongues are provided, to which the second profile is coupled by welding.
  • FR 2 098 274 discloses a frame comprising two U-profiles, which web of the profile is provided with a number of tongues directed inwards the recess of the U-profile.
  • Secondary profiles provided in a substantially perpendicular direction to the U-profiles, extend into the recess of the U-profile. The secondary profiles are coupled to the U-profiles by welding the outer ends of the secondary profiles to the tongues.
  • the present invention provides a frame which can be easily and reliably put together on site, which involves less parts, in particular less small parts which can be easily dropped, provides a clean surface to the members of the frame uninterrupted by bolt heads and is strong and rigid.
  • the present invention relates to a frame as claimed which includes elongate structural elements with a longitudinal web and at least two longitudinal flanges which extend away from the web at an angle, the flanges extending from the at least the same side of the web and the web and flanges forming a longitudinal recess between the flanges, and a plurality of transverse tongues spaced along the web and extending from the web into the recess, the tongues being formed integrally with, and from the same material as, the web.
  • the tongues do not extend further than the envelope of the flanges and web which encloses the recess.
  • the plane of the transverse tongues may be a right angles to the web.
  • the frame comprises at least two first elongate structural elements, each first structural element having a longitudinal web and at least two longitudinal flanges which extend substantially at an angle form the web, the flanges extending from at least the same side of the web and the web and flanges forming a longitudinal recess between the flanges; a plurality of transverse tongues spaced along the web and extending from the web into the recess, the tongues being formed integrally with, and from the same material as, the web; and a plurality of second elongate structural element having two ends, each end of the second elongate structural element being connected directly to one of the tongues of one of the first structural elements.
  • at least one of the outer longitudinal edges of second structural element is flush with an outer longitudinal edge of the first structural element.
  • Fig. 1 shows certain structural profiles which may be used with the present invention.
  • Fig. 1A shows an "H"-profile
  • Fig. B shows a "C"-profile made up of three socalled “Sigma”-profiles
  • Fig. 1C shows a very simple “C”-profile in which the flanges 4 on both sides of the web 2 have the same length
  • Fig. 1D shows a simple "C”-profile in which one flange 4A is larger than the other flange 4B.
  • Fig. 1E to 1H show in cross section further structural profiles which may be used with the present invention.
  • Fig. 1E is often referred to as a "C-plus”-profile
  • Fig. 1F is a "C"-profile
  • Fig. 1G is a "Sigma”-profile
  • Fig. 1H is a "Sigma plus”-profile.
  • All the profiles of Fig. 1 include a web 2 and two flanges 4 which extend away from the web 2 at substantially a right angle with respect to web 2.
  • the two flanges 4 extend away from web 2 at least on one side of web 2.
  • the web 2 need not be a completely flat web but may be corrugated or recessed either longitudinally or laterally in any suitable manner including the provision of holes.
  • the flanges 4 may also include additional shapes such as longitudinal or lateral recesses or folds or seams or holes.
  • the present invention also includes the use of "U"-profiles which may be looked upon as an arcuate web 2 with two flanges 4 attached thereto. Further, the present invention includes structural members with more than two flanges ( Fig. 1A may be considered to have four flanges).
  • Fig. 2 is a schematic representation of a first embodiment of the present invention.
  • a structural element 6 (the main beam) has a profile similar to that described with respect to any of the profiles of Fig. 1 . It includes a web 2 and at least two flanges 4 which extend away from the web parallel to each other and substantially at right angles to web 2 when referred to the plane in which the web 2 lies as well as extending at right angles to the longitudinal axis of the element 6.
  • the flanges 4 extend away from the web at least on one side of the web 2 to form a longitudinal recess therebetween.
  • the structural element 6 is preferably a cold-rolled or cold-drawn metal profile, particularly one made of steel which may be galvanised or painted or coated with any suitable corrosion protection such as plastic coatings and including combinations of galvanising and paint.
  • tongues 10 are formed in the web 2, for example by stamping and bending the web material to form each tongue 10.
  • the tongue 10 is integral with web 2 and made from the same material.
  • the join-line between tongue 10 and web 2 runs in the plane of the web 2 and substantially perpendicular to the longitudinal direction of the structural element 6. This will be referred to in accordance with the present invention as the provision of transverse tongues 10 in web 2.
  • the tongue 10 is bent towards the side of web 2 from which the flanges 4 extend.
  • the web material is a ductile material such as steel which allows such a bend without significant affect on the mechanical properties of the tongue 10.
  • steel with a yield stress between 250 and 420 MPa is suitable.
  • the profile of the main beam 6 has at least a longitudinal flat section between the two flanges 4 from which the tongues 10 may be easily formed. Particularly suitable profiles are "C”, “C-plus”, “Sigma” and “Sigma-plus”. As shown the plane in which tongue 10 lies is perpendicular to the longitudinal direction of structural element but the present invention is not limited thereto.
  • the length of tongue 10 is not sufficient to extend beyond a line joining the ends or extremities of flanges 4. This means that the tongue 10 lies within the envelope defined by web 2 and flanges 4.
  • structural element 6 may be placed flat onto a surface either with the outer side of the web 2 downwards on the substrate or the flanges 4 onto the substrate and tongue 10 will not touch, mark or damage any such substrate.
  • the use of the web material of a main beam has the advantage that the tongue 10 has a material thickness which provides considerable mechanical strength. In the formation of a frame such as a wall, floor or ceiling frame about 80% of the frame is made from lighter weight secondary beams which join two main beams 6 together.
  • main beams 6 The low percentage of main beams 6 means that these can be made from flat strip having a considerable thickness without increasing the overall weight of the frame significantly.
  • the material used for a main beam 6 may be steel with a thickness of between 3 and 4mm whereas secondary joining beams may have a material thickness of between 1.5 and 2mm.
  • the use of the web 2 of main beams 6 to form the tongues 10 is therefore superior to forming tongues or fastening tabs in the lighter gauge secondary beams.
  • Tongues 10 may be provided with circular or oval fixing holes 11 or similar fixing devices which are preferably pre-punched in tongue 10 before it is stamped out and bent from web 2.
  • the punching and bending of tongue 10 may be done in flat metal sheet prior to the cold-rolling process which forms the profile structural element 6 or tongue 10 may be stamped into web 2 and bent after profile structural element 6 has been formed.
  • Secondary beam 8 In order to attach a secondary beam 8 at right angles to a main beam 6 as part of the construction of a rectangular frame the secondary beam 8 is bolted to the tongue 10.
  • Secondary beam 8 has a sigma or sigma+ profile.
  • the secondary beam 8 is be prepared so that it may slide into the recess formed by web 2 and flanges 4 of the main beam 6. As shown in Fig. 3A and 3B this is carried out by removing a portion of one of the flanges 14 so that secondary beam 8 slides into the recess formed between flanges 4 and web 2 of the main beam 6.
  • Two or more suitably located holes 16 are provided which match holes 11 of tongue 10 and which may be used for securing the secondary beam 8 to the main beam 6 using bolts or rivets or similar.
  • the preparation of the ends of the secondary beams 8 may be made in advance.
  • the ends of the secondary beam 8 may be dimensioned so that the end face of secondary beam 8 abuts the inside of web 2.
  • the length of tongue 10 may be relatively short.
  • the asymmetrical end preparation of secondary beams 8 as shown in Figs. 3A and B allows one flange 14 (the upper one in the drawings) of the secondary beam 8 to be flush with the upper flange 4 of the main beam 6. This provides one flat surface, without bolt heads onto which a floor or ceiling boards may be laid or placed directly.
  • a second embodiment of the present invention is shown schematically in Fig. 4 and 5 .
  • the reference numerals used in Fig. 4 and 5 which are identical to the reference numbers of Fig. 2 and 3 relate to the same components.
  • the main difference between the second embodiment and the first embodiment is shown in Fig. 5 and is caused by the fact that the secondary beam 8 has the same width as the main beam 6.
  • Both flanges 14 of the secondary beam 8 are removed at an end portion in order to produce a jointing tab with holes 16 for connection to the tongue 10 through holes 11 of the main beam.
  • the advantage of the second embodiment is that the secondary beam 8 is located symmetrically with respect to the main beam 6 whereas the secondary beam 8 of the first embodiment is not located symmetrically with respect to the main beam 6.
  • both sides of a frame constructed in this manner are flat.
  • the tab at the end of the secondary beam 8 which is connected to the tongue 10 may be less rigid than the similar tab for connection to the tongue 10 of the first embodiment because in the second embodiment both stiffening flanges 14 are removed.
  • web 12 of the secondary member 8 in accordance with the second embodiment has itself a three-dimensional reinforcing structure so that the tab used for connection to tongue 10 maintains more rigidity than a simple flat sheet of metal. For this reason a profile such as a "Sigma" profile is used in the invention.
  • the tongues 10 do not extend beyond the envelope formed by the flanges 4 and web 2 of the structural element 6, the tongue 10 is not easily damaged during transport. Additionally, structural elements 6 may be stacked together as shown in Fig. 7 in a nested way allowing the minimum volume for transport. The tongues 10 can be offset longitudinally to avoid tongues from two beams colliding directly.
  • a further advantage of the present invention is that there are no bolt or rivet heads which project from the web 2 of the main beam 6 on the side which is remote from flanges 4.
  • This allows frames 18 to be placed together as shown schematically in Fig. 6 .
  • Each frame 18 consists of two main beams 6 attached by cross members 8 which are secondary beams and which are connected to the main beams 6 by the tongues 10 as has been described with respect to the first and second embodiments.
  • the holes 12 may be alternatingly placed in front of and behind the tongue 10 in the longitudinal direction of the main beam 6.
  • the end of a main beam 6 may be chosen so that a hole 12 is removed when the main beam 6 is cut to length leaving the tongue 10 firmly attached to the main part of the web 2 immediately at the end of the main beam 6.
  • These frames 18 may be placed together with no space between the abutting main members 6 as shown schematically in the enlarged cross section of the beams 6 joining in the centre of Fig. 6 .
  • the lack of bolt heads means that other coatings, panels or materials may be applied to the outer surface of web 2 without being disturbed by bolt heads.
  • Secondary beam 8 is joined directly to the tongue 10 which is a part of main beam 6. Hence, secondary beam 8 is joined directly to main beam 6. No loose connecting pieces other than bolts or rivets are used to form the frame 18 which reduces the number of parts, speeds up installation and avoids having to carry or fit structural connectors which may be a danger to others or may get lost or stolen or used on other jobs.
  • a further advantage may be appreciated when the frame 18 is used horizontally as a floor support and carries a load, e.g. up to 500 kg/m 2 . Loads on the secondary beams 8 are transferred to the main beams 6 by means of transverse tongues 10. When frame 18 is used horizontally the transverse tongues 10 extend horizontally into the recess between flanges 4 with the plane of tongue 10 being vertical. The downward force on the tongue 10 by the secondary beam 8 is supported by the full width of the tongue 10 where it joins web 2.
  • This design feature combined with the fact that the thickness of the main beam web 2 is preferably larger than the thickness of the secondary web 12 and that the distance of the bolts or rivets to the web 2 is small means that a frame 18 made in accordance with the present invention has a greater load bearing capability, alternatively can be made with lighter gauge material for a given maximum loading.
  • a suitable cross-section profile of a main beam 6 is shown in Fig. 8 .
  • the width W of the web 2 may be typically 140 to 350 mm and the width B of the flange 4 may be typically 60 to 120 mm
  • the ratio W/B is preferably 2 or more, typically 2.5 to 5.
  • the width of the tongue 8 is typically 30% to 60% of W.
  • the length of the tongue Y is typically less than 70% of W, for example 30 to 70% W.
  • the main beam profile is a C or C+ profile and the secondary beam has a Sigma or Sigma + profile.
  • transverse tongues 10 has been described as extending at right angles to the web 2 into the recess between the flanges 4 but the present invention is not limited thereto.
  • the plane of at least some of the transverse tongues 10 may be placed at a different angle. For instance, the plane may be placed at 45° or 60° to the web 2.
  • These angled tongues 10 may be used to connect secondary beams 8 at an angle of 45° or 60° to the main beams 6, respectively while keeping the secondary beam 8 and the main beam 6 in the same plane. This may provide a locking or bracing of the frame 18 as it introduces a triangular structure so that it is more rigid with respect to lateral forces.
  • the angled tongues 10 are made from the same material as the web 2 and only bent through an acute angle so that the holes 11 in the tongues 10 may be accessed through the holes 12 in web 2.
  • Holes 12 may be used for other purposes, e.g. for cables pipes, and other services which need to be introduced under the floor or in the ceiling of a building.
  • the invention has been described mainly with respect to a main beam with only two flanges on one side of the web.
  • the present invention also includes the use of more than two flanges.
  • the tongues 10 may be formed alternatingly extending into the longitudinal recess between the flanges on one side of the central web and in the recess between the flanges on the other side of the central web.
  • the structural elements 6, 8 have been described as being made from metal but they may also be made from any suitable structural material, e.g. glass-fibre or carbon fibre reinforced plastics.
