Description

101557 Thermally insulated log element
The invention relates to a thermally insulated log element according to the preamble of claim 1.
5 Massive logs machined from one or more beams are already known. The problem with such logs is that the requirements for the insulating capacity of a wall formed of logs in structural regulations are becoming stricter. This means that logs of increasingly massive diameter are required to be used for construction purposes. As a result, with the increase in the dimensions of the log, the increase in the raw material and manufacturing costs of the log 10 also results.
A log element is previously known, which comprises side boards and an insulating part made of foamed polyurethane arranged between them. The problem is that such a log element no longer functions in terms of moisture technology like real and genuine log made of solid wood, nor does it correspond to a log that is solid in terms of strength properties. 15 It is a building element which, by its appearance, seeks to imitate a log.
The object of the invention is to provide a new log element in which the thermal insulation capacity of a log is improved in a new way and thus a strong increase in the diameter of the log is avoided and the log still has the properties of a solid log.
The thermally insulated log element according to the invention is characterized by what is set forth in the characterizing part of claim 1. The log element according to the invention comprises a solid log or similar part of substantially wood material. According to the invention, the log element further comprises an elongate insulating board having a width substantially corresponding to the width of the log and fixed to the log side in the longitudinal direction therewith, the insulating board comprising a wood board such as a board or at the same time the outwardly directed surface part of the hir element.
The advantage of the invention is that by means of the insulating plate, the thermal insulation capacity of a conventional log or similar component made of a substantially wood material can be effectively improved without significantly increasing the horizontal dimension of the log element and at the same time the diameter of the log wall. For example, a 50 mm thick insulation board comprising a 30 mm wood fiber insulation part corresponds to a wood layer about 110 mm thick with thermal insulation properties. When such an insulating board is installed on the side of a massive planed log with a thickness of e.g. 2,105,557, e.g. 140 mm, a log element with a total thickness of 190 mm but with a thermal insulation thickness corresponding to a planed log with a diameter of about 250 mm is obtained.
It is also an advantage of the invention that the structure, appearance and moisture-technical properties of a wall or the like 5 made of log elements correspond in all respects to a log processed from a solid wood raw material.
A further advantage of the invention is that by means of the log element the possibilities of using the log in construction can be expanded, because the insulation capacity of such a log element is considerably improved.
A further advantage of the invention is that the insulation board can be suitably pre-coated already at the manufacturing stage at the factory or before installation, whereby e.g. the external wall of the log building is completely finished in appearance and protection with the help of insulation boards. A further advantage is that the outer surface of the wood board of the insulating board can be heat-treated and / or impregnated at the manufacturing stage, for example, in order to improve its anti-rot and heat-insulating properties. Insulation boards thus provide a finished exterior surface for the building.
A further advantage of the invention is that the ribs and grooves of the edges of the wood board of the insulation board close the wall surface into a relatively dense whole, whereby water cannot easily enter the structure through the seams of the insulation board and in particular the wood board.
A further advantage of the invention is that sealing strips can be fitted in the grooves of the insulation boards with ribs and grooves, as a result of which the penetration of water into the structures through the seams of the insulation boards is more effectively prevented.
In the following, the invention and its other advantages will be described with reference to the accompanying drawings, in which Figure 1 shows a wall structure in which a log element according to the invention is applied; Fig. 2 shows another wall structure in which a second log element according to the invention is applied; Figure 3 shows an insulating plate of a log element; and Fig. 4 illustrates a part of two log elements connected to each other in connection with each other, in connection with which a sealing strip is used.

Figure 1 shows a log element 1 according to the invention. The log element 1 comprises a solid log part or log 2 or a similar structural part of wood material and as an additional part an elongate insulating plate 3. The log element 2 of the log element 1 is most preferably way.
The width e of the insulating plate 3 substantially corresponds to the height h of the log 2. The insulating plate 3 is fixed to the side of the log 2 parallel to it. In this case, the log 2 and the insulating plate 3 together form a log element 1, the thickness p of which is the sum of the thickness ph of the log 2 and the thickness pe of the insulating plate 3 and the height h = 10 the width e = width of the insulating plate 3. .
The insulating plate 3 is formed of a cladding plate and an insulating part. The cladding board is realized by means of a wooden board 4, such as a board or a similar layer of wood. Connected to the cladding board or wood board 4 is a substantially wood fiber insulating part 5. The insulating part 5 is made of wood fiber, such as thin wood chips, and a suitable adhesive, such as a wood glue known per se and in general use in the art. The wood fibers of the insulating part 5, such as wood chips, are mixed into a uniform airy mixture together with the adhesive and thus formed into a sheet-like insulator, which is then glued to the wood board 4 to form the insulation board 3.
The wood board 4 is most preferably made of the same wood material as the log 2. In addition, the wood board 4 is shaped with an outer surface 4a corresponding to the side 2a, 2b of the log 2. In this case, the outer side 4c of the wood board 4 may be a straight planed surface, as in Fig. 1, and the long sides 4a, 4b of the wood board 4 may be provided with chamfers 4d, 4e. In this case, the outwardly visible surface of the wood board 4 is similar to the side 2a, 2b of the log 2, in this application the planer log 25.
Alternatively, the outer surface of the wood board 4 may be a circular surface 4c '(shown in broken line in Figure 1) when the insulating board 3 is attached to the side of the round log 2' (also in broken lines in Figure 1). In this case, the second side 2b of the round log 2 'is machined into a straight surface for fixing the insulating plate 3. It should be noted that a suitable concave trough can alternatively be provided in the insulating part 5 of the insulating plate 3 30, to which the side of the round log can be fitted without surface treatment.
The log elements according to the invention are primarily intended for the construction of log buildings. In this case, the log elements are arranged one on top of the other to form walls or the like, as shown, for example, in Fig. 2.
4 101557
Ribs 7 and grooves 8 are arranged on the long sides 3a, 3b of the insulation board 3 and in particular on the long sides 4a, 4b of the wood board 4. The grooves 8 and the ribs 7 belonging to the overlapping log elements 1 are then arranged to one another. In this way, the overlapping log elements form a dense layer of wood on the outer surface of the insulation board 3, which does not easily penetrate the rain-5 water. In addition, similar ribs and grooves can be traced on the long sides of the insulating part 5.
In order to improve the tightness, a sealing strip 9 can also be fitted in the groove 8 of each insulating plate 3, as illustrated in Fig. 4. The sealing strip 4 has a circular cross-section, e.g. round, so that it is easy to install in the groove 8 and it seals 10 the connection between the rib 7 and the groove 8 on the basis of the groove 8 reliably and efficiently. In such a case, liquid water from the joint between the rib 7 and the groove 8 cannot penetrate the log element 1 or the wall structure formed therefrom.
Figure 2 shows another log element 10 according to the invention. This log-15 element 10 also includes a log or log part 11 or the like and an insulating plate 12. The log 11 is formed of two (or more) superimposed glued wooden parts 111 »112. and a longitudinal seam 11 ^. The insulation board 12 comprises a wood board 13 and a wood fiber insulation part 14. In this application, the wood board 13 is formed of two wood parts 131, 13. These wooden parts 131, 13 ^ are longitudinal longitudinal and glued-together parts of the log and the insulating plate 12, between which a horizontal and longitudinal seam 13 ^ is formed. The horizontal seam 11 ^ of the log 11 of the log element 10 and the horizontal seam 13 ^ of the wood board 13 are preferably arranged in the same horizontal plane, whereby the log element 10 looks similar on both sides 10a, 10b and then the wall formed of log elements 10 is preferably similar on both sides. There may be a plurality of said horizontal seams 11 ^, 13 ^, provided that the log 11 and the wood board 13, respectively, are formed from a plurality of parts glued together and joined together by horizontal seams. The wooden board 13 of the insulating plate 12 of the log element 10 is provided with molds 15 and grooves 16 in the same way as the log element 1 of the embodiment of Fig. 1. The embodiments of Fig. 1 and Fig. 2 thus correspond approximately to each other.
Figure 3 shows an insulating plate 17 of a log element according to the invention. This insulating plate 17 comprises a wooden plate 18 and an insulating part 19, preferably glued, attached thereto. The wooden plate 18 is formed of a board or similar wood layer, the longitudinal sides 18a, 18b of in the groove 21. The surface part 18c of the wood board 18 is suitably shaped on long sides and / or in other areas. The surface portion 18c may be a straight planed surface and the long sides 18a, 18b of the wood board 18 may be provided with chamfers 18d, 18e. In this case, the surface part 18c of the wood board 18 resembles a panel board or the side of a log (cf. Figures 1 and 2). The wood board 18 can also be formed of two or more longitudinal parts, between which a rather inconspicuous horizontal and longitudinal joint 22 is then left. The wood board 18 can further be provided with longitudinal grooves 23 on its insulating surface 19 to prevent cracking of the wood board 18.
The insulating part 19 of the insulating plate 17 is formed of wood fiber insulation material in the same way as the wood fiber insulating parts 5, 14 of the log elements 1,10 shown in Figs.
The wooden board 18 of the insulating board 17 and the log element 1, 10, respectively; 4, 13 can be pretreated in many different ways either before the insulation board 17, 3, 12 is formed or before the log element or insulation board is used for construction purposes. Wood board 18; 4, 13 can be heat treated, for example, in such a way that its anti-rot properties and thermal insulation properties are improved. In this case, the wood board is brought to a high temperature in the oven, such as 200 ° C, for a period of time, during which its properties can be optimized and improved in terms of both rot prevention and thermal insulation. On the other hand, the wood board can be impregnated with suitable impregnating agents or painted. In this case, the insulating board 17 or the log element 1, 10, respectively, is completely finished on its wooden board side surface and it is no longer necessary to process it after installation.
It is clear that the thickness of the log element 1, 10 can be changed as required, as well as the ratios ph, e of the thicknesses of the log 2 and the insulating plate 3. The thickness of the wood board 4 is mainly determined by the strength of the structure, but is usually of the order of 20-30 mm.

The invention has been described above mainly with reference to a few preferred application examples, but it is clear that many modifications are possible while remaining within the scope of the inventive idea defined by the appended claims.
