The beam shown in FIGS. 3 and 4 is made up of two beam halves 1 and 2 in a corresponding manner built up, but has a ridge-shaped neck portion 6 'in a manner known per se, which is connected to a corresponding ridge-shaped, transverse recess 7 cooperates in a crossing beam, thereby increasing Tightness is achieved. The insulating layer 3 between the beam halves 1, 2 can be at the apex the ridge-shaped painting part 6 'are pressed together somewhat so that they can easily be pushed into the recess 7 is pressed out and contributes to increasing the tightness.

In Fig.5 and 6 two bars are shown which have neck profiles 8 and 9, which are differently designed are so that the bars can be knocked together perpendicular to each other until they are equal horizontal planes come to rest. In this embodiment, too, there is an intermediate one heat insulating layer 3 between the two in each type of beam symmetrical beam halves. In this way, a well-insulated tight house can be made with the joists around the whole house around the same height. The embodiment is different because of two Types of neck profiles a little more expensive.

If desired, the bar halves can be cut through in

jo large spacing attached support blocks in the space between the space, which is otherwise from the insulating layer is filled, be connected to each other, whereby the beam is given increased strength. Such Support blocks do not significantly reduce the insulating capacity of the beam and give the beam a increased stability if they are attached with the same grain direction as the wooden beam halves, so that they work the same way with changes in the moisture of the wood.

Claims (6)

Patent claims: 1. Wooden beam for building a log house wall, which has at least one tongue or groove formed in one piece with the beam wood on its upper or outer side, characterized in that the wooden beam is formed from two beam halves (z. B. 1, 2) is, between which a layer (e.g. 3) of thermal insulation material is inserted, which extends in the longitudinal direction of the beam and from the bottom of a groove (τ. B. 4) to the top between two tongues (e.g. 5) extends over the height of the beam and can be placed on the opposite longitudinal side of the beam against the layer (e.g. 3) of thermal insulation material of the beam above or below. 2. Wooden beam according to claim 1, characterized in that the thermal insulation material is an expanded Plastic foam material is with great compressive strength and with two mainly symmetrical Balkenhällten (e.g. 1,2) made of wood is glued. 3. Wooden beam according to claim 1, characterized in that it has at least two springs which are formed in that the thermal insulation material has a longitudinal groove (10) between the of the surrounding parts of the wooden beam formed spring (5), and that the thermal insulation material on the opposite longitudinal side of the bar a protruding tongue (ti) between the walls of the surrounding parts of the wooden beam formed groove (4) forms (Fig. 7). 4. Wooden beam according to one of claims 1 to 3, with one or more layers of thermal insulation material, characterized in that parallel to one or more springs (13) through which an insulating layer (3 ") extends at least one spring (12) made of wood in one piece with the Wood part of the Baiken is formed, and that corresponding grooves in the opposite Long side of the bar are cut out (Fig. 8). 5. Cross connection between two walls in wooden houses and made of wooden beams according to one of the Claims 1 to 4 constructed, which have such incisions around a neck area that each wooden beam of one wall with its incision over a neck section in a wooden beam the transverse wall engages, characterized in that the thermal insulation material in each beam extends at least all the way to the top and bottom of each neck section (e.g. 6), and that the Neck parts (z. B. 6) in the longitudinal direction of the beam have such an extension that the Thermal insulation material is subject to strong compression in the transverse direction when the beams are knocked together in a cross connection. 6. Cross connection according to claim 5, characterized in that the beams have such incisions have that the neck parts (e.g. 6) on the top have a ridge-shaped or arched cross-section & ° sen and on the underside a corresponding ridge- or arch-shaped transverse recess (7) have, as well as the thermal insulation material preferably something about the profile of the cutouts of the Wood protrudes. The invention relates to a wooden beam for construction a log house wall, which at its top or bottom at least one in one piece with the Has timber formed tongue or groove. It is known to use laminate panels for various building purposes, which have a layer of Thermal insulation material included, but these panels are typically only used in houses that are above one rigid framework with columns to which the wall panels are attached. With wooden houses like In many other houses, too, the walls are usually insulated by attaching insulating panels within the actual wall and usually at a distance from it. This procedure is right laborious and time-consuming and, when it comes to log houses, causes the inside Side of the beam wall is hidden, which is undesirable, not only from a purely aesthetic point of view off, but also because the inside cladding with insulating material has a certain preservation in the form of Painting and wallpapering requires, while a pure wood wall practically does not require any preservation, once it has been impregnated, varnished or treated in an appropriate manner. To a Avoid covering the wooden structure and thus preserving the characteristic log house taking into account the climate at the location in question and the intended use of the house as a summer or winter apartment so suitably heavy wood is used that it can be used despite The lack of thermal insulation in the houses made it pleasant to stay. The use of the heavy However, due to the high wood prices, beams mean that the houses are relatively expensive and the cost of heating houses of this type will nevertheless be relatively high if the Houses, as it is becoming more and more common, not only as summer apartments, but as leisure apartments that are intended to be used all year round. Another problem that arises with the insulation of "wooden houses, which are made of horizontally lying beams are constructed, linked, stems from the fact that the walls, with the help of tongue and groove as well Cutouts for corner connections, but without a rigid framework, are joined together for a certain amount of time will sink down after building. The collapse is a consequence of the drying out of the wood and is therefore only after Course completed from 1 to 2 years. For a wall that is 2 m high, the collapse is in the Of the order of 5 cm. If such a log house is to be insulated, a system of battens must be used use that are attached to each individual beam so that the wood shrinks for each single beam is not added to a large shrinkage of the whole wall, but on each beam remains distributed. In this case, the insulating material is attached between ilen battens. This procedure is expensive and troublesome because it requires the additional batten construction and there is a risk of that leaks arise in open tongue and groove connections or in the corner connections. Do you want that Avoid using the slat construction, with the known state of the art only that remains Possibility to wait 1 to 2 years before applying the insulating material until the wood is dry so that the collapse is practically complete.
