Definitions

  • the invention relates to a building element with insulation.
  • the "lafting"/logging joint method of building with logs is a part of the historical building tradition in several countries, including Norway.
  • the “lafting” process involves placing the logs on top of one another and joining them together at the corners. Each log is tailored to fit the next by cutting out a v-shaped groove under the log above.
  • moss was used as a sealant between the logs and in the corner grooves. The weight of the timber together with the roof construction compress the walls, keeping them sealed.
  • NO 318375 relates to a laftable, log-like building element with external surfaces of wood or a wood-like material, internal bearing elements and an internal insulating layer.
  • NO 318394 relates to a building element intended for lafting, comprising side walls of a single wooden or wood-like board, the inside of which is provided with a layer of plastic. To the inside of each board is attached a number of frames that give the side walls dimensional stability. An insulating material may also be inserted inside the building element.
  • SE 318 984 relates to a building element in the form of a beam with tongue and groove and with an insulating material placed between two profiled wooden half-beams. At one beam edge, the insulating material forms a tongue that extends into the middle of a groove.
  • CA 2326054 relates to a log member including a core and an outer covering.
  • the core comprises insulating foam material.
  • the coverings are made from wood. This document discloses the features of the preamble of claim 1.
  • US 5115309 relates to a method of converting logs into finished dressed lumber.
  • the logs are divided into segments which may be joined with a filling material between the segments.
  • DE 4344907 relates to a log construction comprising a log wall and an additional wall located at a distance from the log wall.
  • the two walls are interlocked by means of connecting pieces.
  • the object of the invention is to provide a building element with insulation, particularly a log-type building element, which is easy to produce and provides good insulation.
  • a building element according to the invention comprises two elongated outer elements arranged in parallel side by side, at least one insulating element mounted between the outer elements and fixing means for connecting the outer elements and the insulating element.
  • the elongated outer elements are preferably made of wood, for example by dividing a log into two or more parts along the longitudinal direction with the result that the outer elements are composed of two parts of the log.
  • the end portions of the outer elements may be adapted for lafting, where for example in an embodiment the log may be adapted for lafting with a recessed groove near both ends of the log.
  • the outer elements may comprise holes or recesses for receiving fixing means.
  • the outer elements comprise through-going holes for passing through bolts.
  • Other possible embodiments include grooves for accommodating straps and/or holes for insertion of bolts may have an additional recess for inserting plugs.
  • the outer elements may also comprise notches on the surfaces facing the insulating element. The object of these notches is to prevent warping and bending of the outer elements relative to one another and to the insulating element.
  • the outer elements may also comprise several elements connected to one another/combined to form laminated elements. This may be implemented, for example, by dividing a log into several parts and joining the parts together by gluing, thereby forming two separate outer elements consisting of several glued together log elements. A construction of this kind will further prevent warping and bending of the outer elements.
  • the insulating element may be made of any suitable insulating material such as, for example, polyurethane foam, polyurethane sheets, expanded and extruded polystyrene, mineral wool, etc.
  • the insulating element may come in different lengths and shapes. In an embodiment the insulating element extends along the full length of the building element, while in another embodiment it may be of a shorter length than the outer elements.
  • the insulating element is generally elongated in shape and approximately the same height as the outer elements.
  • the insulating element is mounted between the outer elements in such a manner that a part of the insulating element extends over the outer elements in the height direction while the outer elements extend below the lower part of the insulating element, i.e. the insulating element is offset in the height direction relative to the outer elements.
  • At least one end element is connected to the insulating element.
  • the length of this/these end element/s is such that the total length of the end elements and the insulating element is equal to the length of the outer elements.
  • the end element may be mounted between the outer elements at the ends, but at a distance from the insulating element.
  • the transition between the insulating element and the end elements is provided near or in the middle of the joining area for lafting. In this fashion a room/house constructed by lafting building elements according to the invention will have insulation along the full length of the walls, while the part of the wall/elements projecting outside the house (i.e. the lafted corners) have no insulation.
  • the fixing means connect the outer elements to one another and to the insulating element and possibly the end elements.
  • the fixing means may be of any suitable type, but it is particularly advantageous to employ fixing means with little thermal conductivity, for example made of a plastic material or wood.
  • the fixing means are bolts extending through at least the outer elements.
  • Other examples of fixing means may be glue, other adhesives, straps and the like or a combination of these and bolts.
  • the fixing means are bolts extending through the outer elements and the insulating element.
