Definitions

  • the present invention relates to a constructed of wood building wall element.
  • the term "wall” is to describe flat components of a house in general, so not only vertically installed.
  • the material wood is one of the traditional and particularly widespread building materials. He is also experiencing a renaissance in the new building, with regard to the CO 2 problem, the avoidance of non-recyclable waste, with regard to its good insulation properties and good load bearing capacity with low weight and, above all, also due to biological aspects. This applies in addition to the traditional designs, such as the block house construction, especially the prefabricated house and the construction of new buildings to a certain extent prefabricated larger wall elements.
  • the WO 2007/068267 A1 shows a wall element with two support plates spaced from each other by supports, on each of which a wall outer surface forming the wall plate is arranged.
  • the pillars divide the space between the support plate in elongated chambers, which are then each divided by between the supports provided, extending parallel to support and wall panels partitions in an isolation room and an installation room.
  • the CH 247 940 A shows by stiffening strips spaced apart boards panels and has the connection of such elements with transverse to the stiffening bars connecting rods to the object.
  • the boards are fastened with diagonally hammered nails on the stiffening strips.
  • the EP 1 734 200 A1 shows building wall elements with several, each constructed of juxtaposed woods layers that are connected to each other via ridge strips.
  • the woods are in the mentioned prior art in at least two layers in parallel, the woods of one layer are connected to the other layer of wood by opposing grooves and ridges inserted therein.
  • the ridge strips are perpendicular to the orientation of the woods and thus hold not only the two layers but also the woods together in each of the layers.
  • This cohesion can also be ensured by the fact that the ridge strips are used in a very dry state in the grooves and jammed by subsequent swelling on the final moisture in which reduce the dimensions of the grooves and, if the ridge strips are made of wood, increase their size , On the other hand, preferably between the woods in the same position in the final moisture state expansion joints remain, so that the entire wall element can respond to moisture fluctuations in the building distortion-free and largely stress-free.
  • the present invention has for its object to further develop this prior art in an advantageous manner.
  • the invention relates to a building wall element having at least two layers, which have juxtaposed woods and which are connected by means of opposing grooves and ridge strips therein, characterized in that in at least one of the layers, the woods are not tight, between the non-dense woods of the There are at least one layer of gaps that pass along most of the length of timber and perpendicular to the layer, with the woods spaced apart from each other by the space that is at least one-tenth of the width of the woods at the gap transverse to the timber's longitudinal direction.
  • the invention also relates to a method for producing such a building wall element and a method for building a building using a prefabricated wall element of this type.
  • the basic idea of the invention is not to completely fill at least one of the layers of the wall element with wood or, in other words, not to set the wood in it tightly. It should therefore exist between at least a portion of the woods in this situation and adjacent woods of the same location gaps that go well beyond expansion joints, in particular gaps of at least half the width of the woods in this position and perpendicular to their longitudinal direction.
  • the smallest occurring distance between the mutually facing sides of the adjacent woods of the position about the gap is meant. These sides need not necessarily be oriented flat and perpendicular to the layer plane, so that the distinction between different distances may be necessary. Particularly preferably, this smallest distance is over 20%, 50%, or even over 80% of the timber width.
  • the density and positions are selected mainly according to the desired static values.
  • This relates in particular to different requirements for the span in ceilings, ie wall elements with in the assembled state essential horizontal proportion of a total edge length of the wall element, in particular for completely horizontally mounted ceiling elements.
  • the woods in a position with each other are largely the same and if preferably also the ridge strips and grooves perpendicular to the longitudinal direction of the woods, can with largely standardized woods individually in terms of weight, static performance and, of course, costs individually Wall element can be produced.
  • the spaces can also significantly improve the acoustic properties of the wall element. This is true even without additional fillings of the gaps, which will be discussed, solely by the changed mass distribution on the surface and greater decoupling between the individual woods.
  • the invention is basically directed to wall elements in which all layers are not densely covered in the above sense, including an example is given. Many preferred embodiments, however, combine dense layers on the one hand with non-dense layers on the other.
  • the invention also differs from the embodiments of the described prior art in that the woods are aligned in at least one of the non-dense layers with respect to their cross-sectional profile with the longer edge perpendicular to the layer plane.
  • the spaces can be increased in total uniform overall cross-sectional profile of the wood location, which in terms of acoustic properties or other uses of the spaces, see. below, can be beneficial.
  • the timber is thus more stable with respect to bending stress perpendicular to the layer plane. This can because of the buckling strength even with vertically mounted wall elements desired and advantageous, but is especially true for ceiling elements with slope or horizontal orientation.
  • the longitudinal direction of the woods corresponds at least substantially to the direction of fiber travel in the wood.
  • the grooves should preferably have an angle between 45 ° and 135 ° to the wood longitudinal direction. In the preferred largely parallel alignment of the woods across the different layers, a vertical orientation of the grooves to the wood longitudinal direction is preferred. In principle, however, variants are conceivable in which the grooves extend, for example, at 45 ° to the longitudinal direction of the wood and the wood longitudinal direction deviates from one another at different levels by, for example, 90 °. Even with parallel woods in the different layers, the grooves can have a significantly different from 90 ° angle.
  • expansion joints which are already described in the cited prior art, are also preferred in this invention between close-lying woods and are preferably, based on the final moisture state of the wood, over 0.5% and 1% and less than 3 %, 2% and 1.5% of the width of the wood in the layer plane.
  • Typical values for the final moisture content of a built-in wooden construction element are in the range of 8% - 17% humidity, usually between 10% and 14% and i. d. R. between about 11% and 12%.
  • individual woods may be arranged along the direction in the wall element plane perpendicular to the longitudinal direction of the wood at intervals quite considerably above the timber width in this direction in order to obtain a relatively light wall element. If higher static requirements are to be met, not only in the spaces between the woods in the described wall element additional woods can be provided, which divide these spaces more or less evenly. It may also be the woods at the existing positions in the width direction in packages from a Plural woods are provided. For example, triple or five-packs of wooden packages could be tightly packed but still be interspersed between the packages. Preferably, the woods in the packages have the already mentioned expansion joints between them.
  • the interstices according to the invention are not only one or two times per wall element, but provided in a significant number and preferably also regularly, for example between at least one-eighth, preferably one-fifth of the wood location (per wood to at least one side) and preferably over the Width at least approximately evenly distributed.
  • the woods in the packages may, in principle, be glued together or otherwise additionally joined, although the invention is preferably dispensed with.
  • the expansion joints are less important than with a larger number in the width direction adjoining woods, which is why such a connection or gluing does not necessarily disturb.
  • the previously described preferred orientation of the wood with perpendicular to the wall element level standing longitudinal edge of the cross-sectional profile should refer to packages of in the layer level juxtaposed woods on the single wood.
  • a fauxgeleimtes package must therefore not necessarily also have a perpendicular to the wall element plane longitudinal edge of the cross-sectional profile, to still belong to this preferred variant of the invention.
  • the term of the wood here therefore preferably refers to solid wood in the sense of the naturally grown wood piece and not on assembled wood from a plurality of elements.
  • the "wood” according to the invention preferably designates a beam, a board, a lamella or the like, which are sawed from the trunk as if grown.
  • laminated beams are not excluded in principle. If glued wood layers lie in the laminated beam in each case in the layer plane, ie in the direction perpendicular to the layer plane stacked on each other and thereby glued together, resulting in very good strength values, as is generally known in laminated beams. For gluing between adjacent in the layer level wood this applies, at least for substantially horizontally mounted ceiling elements, not in the same way. Accordingly, such a laminated beam with although perpendicular to the layer plane shorter edge of the cross-sectional profile of the woods, but longer edge of the cross-sectional profile of the entire beam, in the embodiment of the invention with the longer cross-sectional profile edge transverse to the layer plane included.
  • tight-lying wood layers are combined with non-dense. It is particularly preferred that at least one of the outer layers of an existing at least three layers building wall element is tight, so forms a largely closed wooden front, while others, in particular inner layers show inventive interstices and adapted in the manner described to individual requirements can.
  • the intermediate spaces not only have the advantage of saving unnecessary weight and unnecessary raw material in individual cases. They can also be used in a variety of technical ways, for example, for thermal or acoustic insulation materials or weighting to improve sound insulation, in particular beds, or as an installation space for electrical or fluid lines.
  • the intermediate spaces can also be used for a combination construction of wood and masonry or clay, so for truss-like techniques.
  • This relates in particular to vertical wall elements of a building, which can be bricked up and / or filled with loam.
  • the term "clay" naturally includes additions to the clay, such as plant fibers.
  • the invention has particular significance for ceiling elements, be it inclined roof elements or, particularly preferred, horizontal ceiling elements.
  • here in a plane additionally provided and running transversely to the other woods in this plane woods may be of particular advantage to produce at least to a certain extent a second clamping direction without having to introduce another level. This may particularly affect the end beam on the edge of the building wall element, which effectively take on a fall function.
  • the attachment of the woods in the wall element can be done in the manner already described in the cited prior art by assembly in a particularly dry state and subsequent swelling on the final moisture, so without gluing. At most, gluing would not offer any particular advantages in connection with the glulam beams described, which in the case of technically correct installation position are regarded as a uniform "wood".
  • profiles on the opposite sides of wood in one layer are preferred, at least if there is no gap.
  • these profilings fulfill a sealing function corresponding to a positive connection.
  • Side surfaces corresponding profiling be provided without them there complete a special function.
  • the ridge strips are preferably arranged so that they each penetrate into at least one of these form-fitting to reduce the Beerkonvetation between the layers.
  • the ridge bar effectively blocks the first section of the expansion joint, with the second section no longer being significantly connected to the layer between the layers as a result of the profiling. In that regard, can not develop beyond the distance between the ridge strips extending Heilkonvetechnischsströmonne larger extent.
  • the number of gratings in the same way is variable and to adapt to the static requirements as the number and dimensioning of the woods.
  • the ridge strips are responsible in particular for the shear forces and the mechanical coupling between the layers, ie the static synergy effect of the layer stack.
  • the gratings need not necessarily be made of wood, but may also be made of other materials.
  • the woods 1 of the lower layer are in relation to the figure and the intended horizontal mounting position "across", ie horizontally with the longer edge of the cross-sectional profile.
  • the opposite is true for the upper layer woods 2, which are "upright", in sets of three. Between the respective outer woods of the three-packs is a more than five times the width of the woods 2 (based on the layer plane) amounting space.
  • the woods 2 are tightly packed within the dreiervole, in which case not designated in detail expansion joints of about 1% to 1.5% of the width of the woods are provided, by the way, in the lower layer with the woods 1. In these expansion joints can in the cited in the prior art described profile interventions (see there the FIGS. 3a and 3b ) be provided.
  • the gratings can, for example, one of the there in the FIGS. 4a-4c have shown profile shapes.
  • the ridge strips in addition to the dovetail-like profiles may each have straight or notched sections, in each case toward the two grooves, between the dovetail profiles, cf. the cited prior art.
  • two-packs and packages with larger numbers of woods to preferably about 15 woods can be used.
  • the Figures 2 . 3 and 4 show largely corresponding ceiling elements, but the dreiervole the woods 2 are packed increasingly dense.
  • the ceiling elements are therefore heavier in the order of the figures, statically more stable (in the front left to right rear facing clamping direction) and provided with less and less space for other purposes.
  • the most right area is in the Figures 2 . 3 and 4 released for clarity in the upper layer.
  • Typical gaps can go up to a range of 600 mm, which can typically be about five times the width of the wood.
  • the spaces can therefore be very different widths, such as between one tenth and five times the width of the wood.
  • the gaps may be in a similar range in terms of absolute dimensions, for example 565 mm for a typical timber width of 60 mm, which amounts to a commercial pitch of 625 mm. So here the gaps can be up to ten times the width of the wood.
  • FIG. 5 is the embodiment of FIG. 1 changed by a survival of Dreiervole forward, so that they can serve as a beam support for support, for example on a projection of a wall wall.
  • Such embodiments are particularly suitable for roof projections or their extension, balconies u. ⁇ .
  • FIG. 6 shows a further variant of this.
  • the upper layer instead of sets of three individual standing upright woods 2 are used in the upper layer, which are each separated from other woods 2 the same situation by gaps. Every second one of the woods stands forward, the intervening woods are cut flush with the rest of the ceiling element.
  • a transversely running wood 4 of the upper layer is provided in the rear region, which runs at an angle of about 100 ° or 80 ° to the other woods 2.
  • a further tensioning direction is given, which of course is less resilient in this case.
  • the ridge strips in the region of the cross member are omitted, which is not mandatory.
  • the beams 2 and 4 can be fastened to each other with all common mounting options, taking into account the static requirements, according to which they are also dimensioned.
  • FIG. 7 shows a similar embodiment, but in which the protruding portions of the woods 2 are slightly bevelled.
  • This is a prefabricated roof element, which is not mounted completely horizontally, but in such a way that the bevelled areas rest horizontally on a retaining wall when mounted.
  • the cross member 4 exactly perpendicular to the other woods 2 the same position and closes the roof element as a closing beam to the rear. He is thus particularly suitable as a fall.
  • FIG. 8 shows an embodiment of a ceiling element compared to FIG. 1 initially another dense upper layer of wood 5 has.
  • This third layer is constructed practically mirror-symmetrical to the bottom layer with the woods 1 and thus closes the ceiling element upwards as a largely closed wooden front, so in particular apart from expansion joints, from.
  • FIG. 9 shows a variant of this with an increased number of woods 2 in the middle position and significantly reduced spaces.
  • FIG. 10 shows a variant of a ceiling element with a lower dense layer and two layers lying thereon with spaces between the woods.
  • the middle layer corresponds to the wood 2 in FIG. 8 in contrast, slightly more than doubled spaces, ie a 2: 1 correspondence between the woods 1 of the lower and the woods 2 of the middle layer.
  • the upper layer of woods 5 corresponds to the middle in a 1: 1 correspondence, but the woods 5 are oriented as in the lower layer, ie horizontally. Due to the vicinity of two non-dense layers with the woods 2 and 5 in this case, the ridge strips designated here 6 between the middle and top layer are also visible from the outside.
  • the ridge strips 3 and 6 do not necessarily have to go through, in particular not the ridge strips 6, but also may consist of individual pieces.
  • continuous gratings are as drawn, which can be seen to improve the stability of the overall element.
  • This embodiment is particularly suitable for the filling of weightings, for example, chippings, for the acoustic optimization of building ceilings.
  • FIG. 11 shows an embodiment of a vertically oriented building wall element.

  • the spaces between the woods 2 can be bricked, for example, the cross member 4 could then form an upper instead of a lower end to the Wall can be placed directly on the foundation. They can also be filled with clay (and aggregates) in the sense of classic half-timbered construction, or with thermally or acoustically insulating material.
  • FIG. 12 shows a consisting of a lower layer with wooden 1 and an overlying non-dense layer of wood 2 existing embodiment in which the woods 1 are laterally on a wall edge as a support.
  • the woods 2 are slightly shortened, so that there is an installation slot. This can for example pass electrical or fluid lines 7 from a gap between woods 2 to the next or in the area outside the ceiling element.
  • FIG. 13 shows a further embodiment in which in an otherwise FIG. 10 Comparable structure, the woods 1 of the lower layer are replaced by below the woods 2 substantially flush with these attached (inverted) T-profile woods 8, which by not drawn in detail (just like the gratings 6 according to FIG. 10 ) Gratologicaln 3, are wedged, and suspended by between the formed by the T-profiles support edges filling wood 9.

  • the interspersed spaces are filled with biological insulation.
  • wall elements arise mainly from the abandonment of large continuous plates and, as far as provided, additionally by the already described expansion joints.
  • the wall elements are particularly suitable as prefabricated elements, because an individual adjustment due to distortion on the site is unnecessary or this is at least comparatively minor. This also applies when used in combination with masonry or clay, which release moisture.
  • the planner can plan wall elements with great dimensional certainty, without first dimensioning them statically. With consistent element dimensions, reasonable compromises between static properties and cost can then be set. This makes it possible in particular to avoid oversizing, which go back to safety margins and then, on closer inspection, go back to elaborate elements.
  • Incidentally only slight source effects occur in the respective timber longitudinal directions due to their preferred correspondence to the fiber direction, and all other transversely appearing and therefore larger source effects can be absorbed by the expansion joints and the intermediate spaces.
  • the composed of many woods in an entangled manner wall elements forgiven practically not. In contrast to plywood or blockboard, the wood is not blocked here and therefore does not build up any comparable tensions, so that the invention is even better suited for large wood moisture changes.
