Definitions

  • a timber element and method for manufacturing the same A timber element and method for manufacturing the same
  • the invention relates to a timber element defined in the introductory part ot patent claims 1 and 2.
  • the invention also relates to a method according to the introductory part of patent claim 15 for manufacturing the said timber element.
  • the cavities or slots are large and wide. In most cases the cavities and slots are meant to be filled with heat insulation material, and what is more with such heat insulation material which does not breathe and thus destroys the natural good moisture resistance properties of the wood material. It is also pointed out that in such large and wide cavities or slots, when they are open spaces unfilled with heat insulation material, air has easy access to circulate particularly via the seams in between the individual timber elements, so that both the theoretical and calculatory increase in the heat insulation capacity brought about by means of the said timber elements is lost, and in practice the heat insulation capacity deteriorates as compared to a similar massive whole wood timber element.
  • the timber element of the invention is characterized by the novel features enlisted in the independent patent claim.
  • the timber element according to the invention meant for building log houses or similar log constructions, is provided with a number of essentially vertical cavity zones that run along the lengthwise direction of the timber element.
  • the cavity zone of each timber element includes at least one narrow, long and deep groove, and in between the said cavity zones, in the lengthwise direction of the timber element, there are zones of wood material.
  • the timber element is formed in known fashion of at least two tightly attached, advantageously glued timber element parts, each of these parts comprising a cavity zone provided with at least one narrow, long and deep groove, and in between the said parts, in the lengthwise direction of the timber element, there are located zones of wood material.
  • a narrow and long groove means a groove where the width to length ratio is for instance 1 : 100 or less.
  • This kind of groove can be made in the timber element by using a circular saw or another similar tool.
  • a deep groove here is a groove where the width to depth ratio is for instance 1 : 10 or less.
  • the groove is arranged in the lengthwise direction to extend at least halfway up the height of the timber element, or, if the timber element is compiled of several timber element parts glued together, to at least halfway up the height of the timber element part. It is also possible that the grooves extend all the way through the timber element or the timber element part.
  • the timber element blank in the method according to the invention for manufacftiring a timber element meant for building log houses or similar constructions, in the timber element blank there is provided a number of vertical, adjacent narrow and long grooves, which extend deep into the timber element bland and/or through the same, and in between the said grooves, there are left wood material zones, whereafter the timber element blank is processed in known fashion into a timber element.
  • the timber element blank can be a blank containing the whole timber element, or a blank conta ⁇ iing only one timber element part.
  • the heat insulation capacity of the timber element is improved.
  • the narrow grooves and particularly the large number of adjacent grooves effectively prevents the heat from conducting in between the vertical outer surfaces of the timber element.
  • Another advantage of the invention is that the natural good features of the timber element, such as good breathing capacity and pleasant appearance, are retained in addition to the improved heat insulation capacity.
  • each cavity zone of the timber element comprises a number of successive grooves, and a number of short wood material tongues - short with respect to the length - in between the grooves.
  • the grooves and wood material tongues of the cavity zone of the timber element are arranged so that the wood material tongues of adjacent cavity zones are set in an at least partly overlapping fashion with respect to each other in the lengthwise direction of the timber element.
  • the locations of the wood material tongues alternate on the transversal plane of the timber element, and consequently it is an advantage of this preferred embodiment that the heat insulation capacity of the timber element improved with grooves is at least roughly equal within the grooved area.
  • Another advantage of this embodiment is that the rigidity and holding strength of the timber element are improved owing to the provided wood material tongues.
  • the grooves and wood material tongues of the cavity zone of the timber element are arranged so that the wood material tongues of adjacent cavity zones are located in an essentially same wood tongue area in the transversal direction of the timber element.
  • the wood tongue areas run through the timber element in an essentially perpendicular direction, and the wood tongue areas are arranged to follow each other at suitable distances in between.
  • the advantage of this embodiment is that the timber element can be cut at the wood tongue areas, so that the cutting surface always resembles the respective cutting surface of a corresponding whole wood timber element.
  • the appearance of the timber element remains similar to a massive timber element also at the cross-cut surfaces.
  • Another advantage of the wood material tongue areas is that they enforce the timber element, which thus remains rigid in spite of several adjacent cavity zones.
  • the adjacent cavity zones are arranged on the transversal plane of the timber element in the vertical middle area thereof, so that on the vertical sides of the timber element there is an essentially unbroken wood material layer having a width of at least 20 mm, advantageously 25-30 mm. With a round log element, these wood material layers at the sides are larger than the above said measure at least in their maximum width. It is an advantage of this embodiment that the grooves in the cavity zone and particularly their orifices located on the top and/or bottom surface of the timber element are effectively sealed while stacking the timber elements on top of each other. Now air is prevented from circulating through the grooves and the slots of the timber elements laid on top of each other and thus from niining the improved heat insulation capacity of the timber element.
  • a particularly advantageous embodiment of the invention is a timber element where the grooves of adjacent cavity zones are directed symmetrically in an alternating fashion, from the bottom surface of the timber element or timber element part towards the top surface thereof and vice versa.
  • the timber element is relatively light. It is clearly lighter than a whole wood timber element with corresponding outer measures. This is due to the fact that wood material is removed from the timber element of the invention at the grooves.
  • the grooves can be arranged, advantageously machine-tooled, into a wet timber element blank.
  • the grooves extend deep into the wood material (even through it), which means that at the drying stage the moisture is effectively removed from the wood material also as regards the heartwood, and consequently the drying time can be remarkably reduced.
  • the drying period can be shortened even by 30-40 % in comparison with the drying of a massive timber element blank. Yet another advantage is the fact that now the timber element blanks can in principle be dried in the same fashion as sawn goods.
  • the drying time is defined mainly on the basis of the thickness of the unbroken wood material layers located on the vertical sides of the timber element blank; the drying time equals to that of sawn goods with nearly the same dimensions.
  • sawdust is left as waste from working the grooves.
  • the sawdust can then be for instance burned and its energy content recovered.
  • the energy used in working the grooves is in principle recovered when burning the sawdust.
  • the timber element sinks and twists less than a corresponding whole wood timber element. It is particularly pointed out that in the timber element according to the invention, where the grooves are arranged symmetrically, the transformations caused by twisting or grinding are slight. Thus the quality of the timber element is improved.
  • the timber element does not split when drying like a massive whole wood element. It is pointed out that the vertical sides of the timber element of the invention, particularly those of an essentially symmetrical timber element, remain unsplit. This means that the quality of the timber element is improved in this respect, too.
