Definitions

• the invention relates to a framework for supporting a partition element according to the preamble of patent claim 1, wall elements for such a framework and a method for producing a partition element.
• the half-timbered construction has been used for the construction of residential buildings for several centuries, a half-timbered field being formed by vertical bars, transverse bars (lower chord, upper chord) and possibly diagonal bars, which are filled in with suitable wall or partition elements. While the framework frames are designed from a static point of view, the partition elements are usually designed for optimal thermal insulation. In the old half-timbered buildings, these partition elements were made of clay / brick elements or other mineral building materials.
• the half-timbered construction is still found in wooden buildings, the half-timbered frame being made from solid wooden beams, while the partition elements usually consist of two spaced-apart, platelike cover layers and the space between these cover layers is insulated from a bed or is filled in by foaming.
• truss girder for the truss frame
• beams made of core-separated small timber are used, so that a certain minimum thickness of the tree trunk is required in order to be able to produce a beam with the predetermined dimensions and with the predetermined strength.
• the outer layers of the tree have to be sawn off until the rectangular basic shape of the beam has a smooth surface. surface areas results.
• This manufacturing method has the disadvantage that considerable quantities of sawn timber are produced, which is usually reduced in size at most and processed into chipboard or other inferior products.
• the half-timbered construction in the conventional form also requires careful drying of the core-separated small pieces of timber, since if the half-timbered beams are not properly dried, there is a risk that they will warp due to fluctuations in temperature and humidity, so that the half-timbered walls will crack.
• partition elements used in the conventional timber frame construction are that only a lack of strength can be achieved. In the case of insulation fillings and insulation foams, it may happen that the entire space is not filled, so that only an inadequate or uneven insulation effect can be achieved. Compartment elements, in particular filled with fillings, can only be reworked afterwards with extreme difficulty, since if the partition element is cut, the fill can at least partially escape.
• Another disadvantage of the known partition elements is that small animals, such as martens or small rodents, can penetrate into the space between the two cover layers.
• the invention is based on the object of creating a truss and partition element for such a truss, in which sufficient strength and thermal / acoustic insulation can be achieved with minimal expenditure of material.
• This object is achieved with respect to the framework by the features of claim 1 and with regard to the partition elements by the features of claims 6 and 14 respectively.
• Claim 12 relates to a method for producing a partition element according to claim 6.
• the framework according to the invention which was developed by Ms. D. Graf, is to be called "framework 2000".
• the truss according to the invention is characterized in that the truss girders (for example cross bar, vertical bar, diagonal bar) are made from several interconnected planks, so that small timber that could not be used in the conventional design can also be used to create the truss girder , since the small wood cross-section was too small to produce one-piece beams with the required cross-sectional dimensions.
• the truss girders for example cross bar, vertical bar, diagonal bar
• the corner connection of the half-timbered girders was made by slot and tenon connections, which were incorporated into the solid material of the heartwood and thus required considerable manufacturing effort, the tenons and slots in the solution according to the invention can be easily broken or interrupted Extend the planks.
• the lattice girders can thus be manufactured at a considerably lower cost than the conventional construction, since on the one hand class II or III timber can be used, which were not previously intended for such high-quality uses, and on the other hand the work involved in creating the slots and Pins (grooves and tongues) could be simplified considerably compared to the conventional production method.
• the type of construction according to the invention also makes it possible for a large proportion of the construction volume to be provided with one's own contribution, so that the overall construction costs can be reduced.
• the truss girders are particularly easy to manufacture if they are formed from three planks - a central plank and two outer planks surrounding them.
• the slots of the bars can be produced by shortening, resetting or removing the central planks and the pins by resetting the outer planks in the longitudinal or transverse direction in accordance with any combination of features of claims 3 to 5.
• the first partition element according to the invention used for such a framework has a multi-layer structure, each layer consisting of a board layer, an insulation layer formed thereon and a spacer slat layer.
• the next layer of a plank layer, an insulation layer and a further spacer slat layer is then supported on this spacer slat layer. It is particularly preferred if the spacer slat layer rests on the insulation layer, so that the latter can be applied over the entire surface of the board layer.
• the two cover layers of the partition elements are each formed by a plank layer, the spacer battens ensuring that the predetermined spacing of the plank layers is always guaranteed. Since the insulation layer is applied over the entire surface and held by the spacer slats, the insulation and thus an uneven insulation effect is excluded.
• the spacer slats have the further advantage that small animals cannot penetrate into the spaces between the cover layers.
• weak woods of class II and III can again be used, so that the material costs for the manufacture of the partition elements are likely to be significantly lower than with conventional partition elements, in which either high-quality woods were used as cover layers or cheap Press materials that are neither comparable in terms of strength nor in terms of insulation effect to the board layer according to the invention.
• Top layers (outer plank layers), further finishing layers are formed as visible surfaces.
• Final layer can then have recesses for receiving
• the individual layers and layers of a compartmental element are advantageously connected by suitable connecting means such as nails or staples.
• the subordinate claim 12 relates to a particularly simple method for producing the aforementioned partition element according to the invention.
• an assembly frame is preferably used for old buildings, on which a first board layer is first placed.
• a prefabricated wall structure is used as a mounting frame turns.
• An insulation layer is then applied to this board layer, which is preferably designed as an insulation mat.
• the spacer slats are then placed, their longitudinal axis running transversely to the longitudinal axis of the boards. This is then followed by further layers, it being preferred that a total of three layers of boards, insulation layer and spacer slat layer are provided.
• a final board layer is then applied as a top layer to the spacer slat layer of the nth layer.
• the bevel element can be cut to size, whereby due to the full-surface insulation layer and the multiple subdivision over the spacers, practically no empty spaces can arise and the required strength is also maintained.
• a multilayer structure is likewise formed by a multiplicity of adjoining cross layers, each cross layer being formed by two wooden boards, each with three machined peripheral edges and one bark edge.
• the wooden boards of each transverse layer are arranged so that the edges of the bark lie opposite one another, so that the outer edges of the transverse layer are formed by the peripheral edges of the two wooden boards.
• the two bark edges form a parting line running approximately along the center line of the transverse layer.
