Definitions

• the present invention is concerned with a construction element whose interior part is at least partly hollow and/or whose interior consists of a preferably heat-insulating material nd at which con ⁇ struction element at least the faces remaining visible at the outside and inside faces of the building are provided with wooden surface or at least with a pattern similar to a wooden surface.
• the construction element in accordance with the invention is characterized in that at least those wooden faces, or faces with an appearance imitating wooden faces, that remain visible on the construction element are made of thin material layers such as, for example, of a cover layer that has been glued out of layers of veneer, that is at both sides outwardly con ⁇ vex, and whose appearance corresponds to a traditional log made of timber, and that the cover layer of the construction element is supported in its shape by means of end pieces of the construction element, which have a corresponding convexity shape, and possbly by means of one or several support pieces placed between the said end pieces and having a shape corresponding to the shape of the end pieces.
• the construction element is of low weight, its dimensional accuracy is good, and, what is most important, the dimensional accuracy is also retained. Thus, deformations in the complete building are very little.
• the construc ⁇ tion is excellent, and in practical construction work, there are no limiting factors in respect of the length and thickness of the construction element.
• FIG. 1 is a perspective view of a construc ⁇ tion element in accordance with the invention with the cover portion partly cut-off.
• Figure 2 shows the frame construction of the construction element shown in Fig. 1 ,
• Figure 3 shows the forming of the end pieces out of veneers by rolling.
• Figure 4 shows a construction element provi ⁇ ded with a notch for angle joint as a side view
• Figure 5 shows the construction element of
• Figure 6 shows the joining together of the construction elements.
• Figure 2 illustrates the frame construction of the construction element, wherein the end pieces 6 and a support piece 7 are bound together by means of a frame piece 9.
• the end pieces 6 are manufactured so that the ends of the construction element 1 resemble a solid log. This is achieved either by cutting the end pieces 6 out of solid timber or by first rolling a log in the way schematically shown in Fig. 3 and by then cutting the end pieces out of it.
• the rolling of the veneers 10 and 11 may be performed around heartwood, or the heart- wood or a piece corresponding to it may be fitted into the end pieces 6 afterwards, e.g., by machining.
• the end pieces 6, and possibly also the support pieces 7 to be manufactured in this way, are compressed into purposeful shape after the glueing and rolling, or the rolling is performed directly in view of obtaining the desired shape.
• the pattern corresponding to annual rings is formed by glueing and rolling veneers of two species of wood of different colours alternatingly, whereby they in this way produce a cross-sectional pattern visually resembling the summer growth and the autumn growth.
• the top face of the construction element 1 is convex and the bottom face correspondingly concave.
• the top face and the bottom face of the con ⁇ struction element may also be plane f ces, as is shown in Figures 4 to 6.
• a cover layer 2, 3 is formed around the frame construction (Fig. 2) so that the inner layer 3 is made of fibreglass laminate and the surface layer 2 of wood veneer.
• At least the faces of the construction ele ⁇ ment that remain visible at the outer and inner faces of the building are wood-faced or at least wood-face- patterned.
• the faces of the construction element 1 that remain visible and that are made of wood or have an appearance imitating wood consist of thin material layers, such as, for example, of a cover layer 2, 3 that has been glued out of layers of veneer, that is at both sides outwardly convex, and whose appearance cor ⁇ responds to a traditional log made of timber.
• the construction element 1 is, in the way of the logs of a conventional log building, provided with preferably machined notches 8 for angle joints in view of joining the said construction elements 1 together in the way of logs as layers one above the other, as comes out from Fig. 6.
• the joining together and sealing of two construction elements 1 to be placed one above the other is performed preferably by means of some adhesive substance suitable for the purpose.
• the construction element 1 may be allowed to remain hollow by omitting the heat insulation 4, in which case the construction element is supported by the frame construction in accordance with the principle of Fig. 2.
• the frame piece 9 is by no means indispensable in the construction, but it facilitates the handling of the end and support pieces 6 and 7 when the cover part 2, 3 is being glued around them.
• the construction element 1 is, however, preferably filled with heat insulation 4 partly or com ⁇ pletely.
• the heat insulation may be fixed, e.g., as ready pieces to the frame construction shown in Fig. 2 before the cover layer 2, 3 is applied, or, on the other hand, the heat insulation, such as polyurethane, may be extruded into the construction element 1 after glueing of the cover layer 2, 3.
• the parts supporting the cover layer 2, 3 of the construction element 1 in its shape may be made of one piece with the heat-insulating part in its interior, in which case the end pieces 6, the support pieces 7, and the heat insulation 4 in the interior are included in one unified frame piece, which has been brought into the form required by the construction element concerned and which is made, e.g., of poly- urethane.
