Definitions

  • the present invention relates to a metal space framework consisting of individual elements for the construction of buildings. It is known to build trusses made of metal profiles. Such a proposal is known for example from German Offenlegungsschrift DE-OS 31 30 427. Another proposal emerges from US Pat. No. 4,205,497.
  • FR-A-21 84 676 describes a construction skeleton for buildings of various types, which consists of square, metallic, profiled columns on which crossbeams can be attached using gusset plates. However, this results in a direct metallic connection without an insulating intermediate layer, which forms a thermal bridge between the inner and outer skin of the building. Filling pieces, preferably made of hard rubber, can be hammered into the profiling strips, which then serve to support and fasten wall parts, door frames, windows and the like. These embossed fillers do not have a supporting function.
  • the metal skeleton assembly houses which have been further developed from wooden building skeletons, mainly in the United States, for cost reasons, in which essentially the wooden truss is replaced by metal profiles the lack that these prefabricated houses can not be used in all climates.
  • the metal profiles form thermal bridges between the inner and outer skin, which is disadvantageous both if the houses have to be air-conditioned on the inside due to high outside temperatures or heated inside because of low outside temperatures.
  • the previously known prefabricated houses with a metal skeleton can only be used in balanced temperate zones. In all other zones, the operation of these prefabricated houses is associated with high energy consumption. Due to the thermal load fluctuations, building damage occurs too quickly after a certain period of use. Cracks form and moisture penetrates into the building.
  • the invention further relates to an insulating spacer for use in the space framework according to the invention.
  • a versatile metal skeleton is created according to the invention, in which all problems of heat transfer between inside and outside are overcome. This applies to thermal insulation or insulation as well as the avoidance of tension and condensation.
  • the skeleton uses few, namely essentially three types of elements and profiles, thereby allowing rational division of the prefabrication in a stationary operation, easy transport to the place of use and less expensive assembly.
  • the skeleton consists of sheet metal profiles that can be manufactured inexpensively and can be prefabricated in a uniform manner. Since there is no need to specify a grid, these can be arranged in order to adapt to the static requirements in this way without having to keep profiles of different structural strengths in stock.
  • a spatial framework skeleton is built up from prefabricated metal profile and flat material elements.
  • a load-bearing element is a vertical support, which is differentiated according to the installation location of this support in the spatial framework according to outer wall supports 10 or 40 and pure inner wall supports 50. However, all advantageously consist of four identical individual profiles 14 and 15.
  • a house corner with an outer wall support 10 can be seen from four identical individual profiles 14 in the form of an angle, which in this case are composed of an inner profile 14a.
  • the angle profiles have flat legs 16 and 18 on the inside and outside, which have bevels 20 and 22, respectively.
  • the legs 16 are located in the area of the outer wall and the uniform legs 18 are located in the inner wall area.
  • Edge brackets 20 and 22 serve to stiffen the profiles 14a and 14b, the outer bends 20 also serving to fasten an outer skin 12.
  • a support 10 modified with respect to the embodiment according to FIG. 1 with the angle profile 15 is shown in more detail in FIGS. 2 and 2a. The modification is that each leg of the angle 15 has a groove 19 drawn into the interior of the support 10.
  • this channel 19 there is a spacer 26 or 27, which is described in more detail below, in such a way that a fastening means remains concealed within the channel 19 and a smooth leg contact surface for the horizontal support 60 with its webs 64 can be connected in this area.
  • the principle is the same when using both angle profiles 14 or 15.
  • the representation of the principle is simpler on the basis of the profile shape 14 and in practice the profile of the angle 15 is preferred because of the better design of the knots.
  • the support 10 is composed of the four identical individual profiles 14a and 14b or 15a and 15b in such a way that a clear distance 36 remains between opposite legs 16 and 18, respectively.
  • This distance 36 is particularly important between the legs 16 of an outside profile 14b or 15b and the legs 18 of an inside profile 14a or 15a. At this point, any metallic connection between the legs 16 and 18 over the distance 36 is avoided. This eliminates any metallic heat or cold bridge between the elements on the outside and the elements on the inside of a building constructed according to the invention.
  • FIGS. 5a and 5b An exemplary embodiment of how a mechanical connection is made available, which on the one hand avoids any heat flow in the connecting material and yet on the other hand ensures a good mechanical connection and strength, is shown therein.
  • the illustrated embodiment shows in the inner part of the two representations a releasable mechanical connection 26 which can be used wherever elements on the outside with elements on the inside of the building are to be kept at the desired distance 36.
  • This connection 26 consists of a non-metallic insulating body 28 without thermal conductivity and of sufficient strength. It can be hard rubber or a plastic body. In addition, a certain elasticity of the material is desired for sound insulation.
  • Mechanical connecting elements for example threaded screw pins 30, are embedded in the body 28 so as to be resistant to torsion, tension and compression, axially aligned with one another. The torsional, tensile and compressive strength is achieved in that the screw pins 30 end inside the insulating and spacer body 28 in an anchor 32, which can be a simple radial widening, but also a star-shaped plate or the like.
  • the two armatures 32 are in turn kept at a sufficient distance within the insulating and spacing body 28, in particular if these armatures 32 are made of metal in order to avoid any heat flow.
  • the screw pins 30 are intended to protrude through corresponding openings in the legs 16 and 18 and the finished connection is made by nuts 34 during assembly.
  • other detachable or non-detachable connections can also be provided instead of the screw connection.
  • screw pins it is possible to provide hollow rivets or similar connecting elements.
  • the insulating spacers 28 designed according to FIGS. 5a and 5b are arranged in all corners of the building and outer wall support elements to avoid heat flow between the outer parts, such as the legs 18, which run parallel to the outer skin 12, for example one above the other in a corner support 10 at the required intervals.
  • simple, continuous metal spacers 27 can be used between the legs 16, which run transversely to the outer skin 12, in order to save costs. A heat flow need not be prevented in this area since both legs 16 are located in the same outer area of the spatial framework anyway.
  • the connections of a diagonal band 80 shown in FIGS. 5a and 5b are used only at those connection points at which such a diagonal band 80 is actually to be connected, which of course applies to only a few such connection points. Therefore, this further embodiment is described in more detail below in connection with the diagonal bands. For most connection points, only the inner part of the spacer 28 according to FIGS. 5a and 5b without a wrapping diagonal band 80 is decisive.
  • FIG. 3 there can be three different supports seen in cross section.
  • the support 10 already described in detail above is located in an outer corner of the building.
  • Adjacent supports 40 are located in the flat area between the outer and inner skin and there are different supports 50 in the interior of the building.
  • FIG. 4 the section marked in FIG. 3 with the three different types of supports is shown in more detail.
  • the support 10 is located in a corner of the building.
  • a further support 40 is located at a distance in the direction of the outer skin 12, it being noted that the representations according to FIGS. 3 and 4 are not true-to-scale representations of an actual building, but a schematic representation of the principle.
  • the support 40 is also made up of four identical profile elements 14 as the support 10. However, while the support 10 in the corner of the building has a distance 36 in two intersecting planes or outer walls and is therefore set to a distance 36 in each connecting plane of the elements 14 , the distance 36 need only be maintained in the support 40 parallel to the outer skin 12 by inserting the insulating spacer elements 26 in the manner described above.
  • the legs of the profiles 14 can be placed directly on top of one another and connected to one another by simple connecting elements 24 such as screws or rivets.
  • a support 50 which is located entirely inside the building, is in any case constructed with legs which are connected directly to one another by connectors 24, as can be seen from the part below in the illustration in FIG. 4. Both supports 40 and 50 are statically connected with a diagonal band 80 in addition to the horizontal main beams not shown in this illustration.
  • an inner support 50 is shown with the profile angles 15, which are connected directly and without spacing to rivets 24 in the channels 19. Like all other elements, the support 50 can be filled on the inside with insulating material 43.
  • This infill of a prefabricated house skeleton is common and is only mentioned here for the sake of completeness. It is also known to close off the wall structure on the inside with a clamping plate 48.
  • Figure 6 is used to provide a schematic perspective overview of a composite spatial framework and to explain those levels that are also installed.
  • leg purlins 100 At the bottom are all vertical supports (10, 40) in the wall area in leg purlins 100, which according to FIG. 7 are designed according to the distance 36 so that all feet 42 of the leg 10, 40 are adjusted and with the legs of the preferably U-profile leg purlins 100 in can be connected in a suitable manner.
  • there are diagonal tension bands 80 between adjacent supports 10 and 40 which align the spatial truss when tensioning turnbuckles 82 and make it angularly rigid in all two wall levels.
  • the space defined by the distance 36 and extending through each outer wall therefore not only enables an advantageous strict separation of the outer wall and inner wall structure, but also a suitable space for a diagonal bracing.
  • Perforated flat strip material can preferably be used for the diagonal bracing.
  • FIGS. 6, 8, 9 and 10 there are vertically inserted dividing profiles 90 between the supports 10, 40 or 50 composed of four individual elements, which on the one hand serve to provide sufficient support for optionally insertable, soft lining material 94 and on the other hand one To provide additional static support for deriving forces that are introduced from the ceiling via cross members into the truss wall, as will be explained in more detail below.
  • additional fastening surfaces are provided for the inner or outer skin.
  • division profiles 90 are set in pairs in the area of an outer wall in the purlins 100, but according to the invention such that a distance 92 (FIGS. 6, 8, 9 and 10) is maintained in the direction of the longitudinal axis of each outer wall 12. With this spacing 92 in the area of the outer wall infill, thermal bridges are avoided due to the metal cross-sections of the dividing profiles 10 which are too closely adjacent and which penetrate the insulating material 94 or the air layer of the outer wall infill located in this area transversely thereto.
  • a connection for a circumferential horizontal main beam 60 is provided with or without an additional connecting angle 76, which is in an embodiment 1 consists of angled profiles 62 arranged in pairs.
  • Each profile 62 has a vertical web 64, on which a box profile 66 is folded at the top and bottom.
  • the web 64 is bent at right angles to a flange 68, which is folded back parallel to the plane of the web 64 to an outer web 70.
  • the box section 66 is finally completed by a transverse flange 72 with an edge 74.
  • Such a profile 62 can be folded in one operation and offers sufficient static strength, whereby the connection between the edge 74 and the web can remain open.
  • mechanical improvements in the section modulus of the carrier 60 can also be achieved by punching points or by attaching welding points. This can be achieved in a simple manner in the manufacture of profiles on the same machine, so that an increase in strength does not result in any particular manufacturing difficulties.
  • secondary beams 84 can be inserted into the main beams 60, which are of uniform construction and have a smaller cross section.
  • the main and secondary beams can, however, also be designed in accordance with a modification from FIGS. 2 and 8 in such a way that the U-legs end with outer webs 70 at low loads and have only one retracted edge 71.
  • the retracted edge 71 is brought in a direction that is suitable for holding inserted insulation material.
  • the webs 64 are connected when the horizontal main girders 60 with the supports 10, 40 or 50 at floor level are connected to the outer legs 16 and inner legs 18 of the supports 10 or 40, a distance being established between adjacent webs 64 of the same carrier 60, which is greater than the distance 36 is specified. This also ensures a separation of the outer and inner walls in the area of the horizontal beams and any thermal bridge is avoided.
  • the insulating spacers 26 are used for this purpose, as shown by way of example in FIG. 1 on the left. In contrast to the illustration in FIG. 5b, these spacers 26 usually have an angular and not a round outline.

  • the loop 33 is closed with fastening means 35.
  • connection points for the diagonal band 80 are produced at the junctions with the spacers 26, for which spacers 27 made of metal can also be used, to the extent that this diagonal band 80 is required.
  • the requirement follows from the static load and the necessary bracing. It will normally not be necessary to provide 10, 40 or 50 crossing diagonal bands in each field between supporting columns.
  • the box-shaped profile 66 according to FIGS. 7 and 8 can each be provided with a dovetail-shaped or other-shaped longitudinal groove 67.
  • the web 64 of the inner profile 62 can be connected to the inner leg 18 of the support 10 or 40 and the outer web 64 of an outer profile can be connected to the outer leg 16 of the support 10 or 40, so that the distance 36 is also preserved between the outer main beam 60.
  • secondary girders 84 are inserted to form a load-bearing floor ceiling according to FIG. 8, which have the same structural shape as the main girder 60 and are laid on a suitable grid scale and are connected to the main girders 60.
  • 11 and 12 show a further modified embodiment of the outer wall region part from the insulating body 28 separating the inner wall region parts without thermal conductivity and with sufficient strength. All lines previously described are identified by the same reference numbers.
  • This modified spacer 28 can be used according to FIG. 11 in elevation or according to FIG. 12 in the plan in the support area of the outer skin. 11 can also be seen as an example of a connection in the horizontal beam area.
  • the spacer 28 consists of a plywood board 29 and is inserted between the respective metal parts between the outer wall area 12 and the inner wall area at a distance 36.

Abstract

Dans une charpente tridimensionnelle auto porteuse statique de construction de maisons, les charpentes murales n'ont qu'une fonction d'isolation et pas de fonction statique. Des profils métalliques sont réunis à des intervalles voulus et utilisés comme piliers (10) et poutres (60). Dans la région des parois extérieures (12) ils sont réunis de sorte à éviter la formation de ponts de chaleur entre des éléments agencés à l'intérieur et à l'extérieur.
