Definitions

  • the invention relates to a block plank for the construction of wooden walls according to the preamble of claim 1 and a method for their production.
  • logs For the construction of wooden houses and other buildings, logs are used, which can have an essentially rectangular or else a rounded cross-section with flats.
  • the problem with the walls made of block planks is that the walls settle due to shrinkage and that warping can also occur in the wood. This can cause the wooden walls built up with conventional logs to leak.
  • the invention has for its object to provide a block plank for the construction of wooden walls, which maintains high dimensional accuracy even after a long time.
  • the log according to the invention has, at least on its lower support surface, a wedge-shaped longitudinal slot tapering towards the heart of the log.
  • An elastic insulation material can be used in this longitudinal slot, with which the logs stacked one above the other to form a wall lie sealingly on top of each other.
  • the wedge shape of the longitudinal slot arises on the one hand during the drying process, because the previously slotted trunk log is so pulls together that a longitudinal slit initially just widened V-shaped. If further longitudinal incisions are provided in the region of the later upper side of the log before the drying process, it is particularly advantageous to position them so that they are located in the area of tongue and groove connections which are formed between the bearing surfaces of the logs.
  • a development of the invention therefore provides that longitudinal incisions are made in the webs formed on the top of the logs, these webs being part of the tongue and groove connections mentioned. The fact that the additional longitudinal incisions are in the upper webs practically does not affect the properties of the finished wooden wall.
  • the longitudinal cut leading to the heart of the log and the other upper longitudinal cuts have the great advantage that uncontrolled crack formation is avoided during the subsequent drying process.
  • the logs sawn after the drying process result in logs with crack-free side surfaces, which means that high-quality log walls can be built accordingly.
  • the invention is also based on the object of providing a method for producing high-quality logs for the construction of wooden walls.
  • the logs used can be dried with or without a bark, preferably in a vacuum drying process, to a wood moisture content of, for example, 11%, the longitudinal cuts previously made avoiding uncontrolled other crack formation on the logs. After the drying process, the logs can be cut to the finished size of the logs, and the longitudinal cut to the heart of the log can also be milled to a specified size. This gives block planks that have a high degree of dimensional accuracy and with which sealing problems are certain can be avoided. Optimal sealing of the finished log wall is achieved by the insulation materials introduced into the V-shaped longitudinal section, whereby ecologically harmless insulation materials can be used.
  • FIG. 1 shows a log with a longitudinal section leading to the heart before drying
  • FIG. 2 shows the log from FIG. 1 after drying
  • FIG. 3 several logs stacked for drying
  • FIG. 4 completely cut logs as part of a log wall
  • FIG. 5 shows a log wall from above in the area of an end face
  • FIG. 6 sawn-in log as a model before drying
  • FIG. 7 joints of feathered logs sealed with feather keys
  • Figure 8 is a perspective view and Figure 9 is a plan view of a corner plating on a log house.
  • FIG. 2 the front view of a log 1 is shown, which has a longitudinal slot 3 leading to the heart 2. If this log is dried to, for example, less than 15% wood moisture, the wood shrinks in such a way that the cross section or the end view changes as shown in FIG.
  • the Longitudinal slot 3 tapers in a wedge shape to the heart 2, so that one can speak of a now V-shaped longitudinal slot 3.
  • the logs 1, as shown in FIG. 3, are flattened on their lower contact surface, where the longitudinal slot 3 is located.
  • the logs 1 shown in FIG. 3 are additionally provided with longitudinal incisions 4, 5 in the upper area to ensure that no uncontrolled cracking occurs in the log during the drying process.
  • the logs 1 of FIG. 3 are cut to the finished log size, for example logs as partially shown in FIG.
  • the logs 6, 7 have an essentially square cross section and are provided on their lower bearing surface 8 and on their surfaces 9 with longitudinal grooves 10 and corresponding webs 11 running parallel to them.
  • the longitudinal grooves 10 and the webs 11 form tongue and groove connections 12.
  • the longitudinal slot 3 is widened in a V-shape after the drying process, as shown in FIG.
  • the V-shaped longitudinal slots 3 are milled to a uniform dimension on the logs 6, 7, so that insulating material 13 can be used equally in each of the longitudinal slots 3.
  • the longitudinal slots 3 can also be milled to another cross-sectional shape, not shown here. Their cross-section can be rectangular or semi-oval, for example.
  • the insulation material 13 slightly protrudes from the lower support surface 8 in the unloaded state, while it is elastically compressed between the tongue and groove connections 12 from the top of the block plank 6 and thus a secure seal between the two block planks 6 , 7 guaranteed.
  • the longitudinal incisions 4, 5 provided in FIG. 3 are positioned in the area of the webs 11 in the finished block planks 6, 7.
  • further longitudinal slots or longitudinal incisions could be made on the upper side 9 and on the lower contact surface 8 if this is expedient due to the nature of the wood or due to other requirements.
  • the front cover 14 of a log wall 15 can be seen.
  • the cover 14 consists of two glued solid planks 16, 17, shown hatched here, which are connected to the block planks 6, 7 by means of screw or nail fastenings 18, 19.
  • the end faces 20 of the logs 6, 7 are cut in a wedge shape.
  • a threaded rod 21 In the free space between the cover 14 and the end face 20 there is a threaded rod 21 with which the logs are braced.
  • the wall thickness is 36 cm.
  • Figure 6 shows the preferred form of a log provided for drying, since such models are optimally stackable.
  • the block planks 6, 7 used in FIG. 7 have on the upper side 9 opposite the lower support surface 8 parallel longitudinal grooves 21 which correspond to the longitudinal grooves 10 formed on the lower support surface 8.
  • Strongly pre-dried feather keys 22 made of wood are inserted in each of two longitudinal grooves lying directly one above the other, so that press fits between the stacked logs 6, 7 on the feather keys 22 with increasing moisture arise.
  • the feather keys 22 have a degree of drying of preferably less than 10% moisture before insertion into the longitudinal grooves.
  • a tension spring 23 which penetrates the log plank vertically and transversely to the longitudinal direction of the log, is inserted into the logs in the area of the corner plating.
  • the log screed From their outward-facing end face 25, the log screed has a keyway 24 directed towards the tension spring 23, into which a wedge 26 which can be driven at the end is inserted on the end face of the screed. If shrinkage occurs, the wedge can be driven and the corner cladding retightened and made windproof. For optical reasons, the wedge 26 can be covered by a removable cover plate.
  • the block planks for the corner cladding of the outside walls of a block plank house can each have a vertical, expandable longitudinal slot from their outward-facing end face to the area of the corner cladding, which is preferably designed as a keyway 24. What is important here is the possibility of the logs being driven apart in order to compensate for any shrinkage that occurs and to drive the logs to the size sawn out in the area of the corner covering and to seal them against one another.

Abstract

L'invention concerne un madrier destiné à la construction de murs en bois de maisons et d'autres bâtiments par superposition de plusieurs madriers (6, 7) disposés horizontalement. Ce madrier présente au niveau de sa surface d'appui inférieure (8) une fente longitudinale (3) en forme de coin allant en diminuant vers le coeur (2) du madrier (6, 7). L'objectif de l'invention est de créer un procédé permettant de produire des madriers de ce type (6, 7) dont le bois présente une humidité réduite. A cet effet, les grumes (1) utilisées sont pourvues, avant l'opération de séchage, d'au moins une fente longitudinale (3) s'étendant jusqu'au coeur (2) de chaque grume (1). Les grumes (1) sont ensuite séchées dans une chambre de séchage de façon à présenter une teneur en humidité inférieure à 15 %, de préférence 11 %, puis elles sont sciées de façon à produire des madriers de dimensions voulues.
