The specific embodiment
In first embodiment of frame construction shown in Figure 1, frame construction is the window frame with two side components 1 and 1a, bottom parts 1b and top part 1c.As will be in the back more detailed description ground, in general principles of the present invention, in the principle that the core that promptly has a core component that comprises heat-treated wood is encased by the plastic packets coating, the structure of each parts can be different.Yet, hereinafter will be only with reference to right side members 1.
In the photo of the view of Fig. 2 and Fig. 3, can see viewgraph of cross-section according to the side component of window frame of the present invention.Side component 1 comprises core, and this core is made of the core component 2 of heat-treated wood, and core component 2 is the plastic packets coating encapsulation of surface course 3 forms of plastic material.Surface course 3 is formed by foamed polyurethane.Wooden core is processed into long units by molded or chamfering, perhaps thinks favourable, and very the person can form the whole side component of window.Therefore, shown cross section comprises the recess 4 and 5 along frame side part, and described recess 4 and 5 is not used in this position, but has other function.Recess 6 is suitable for installing lining.With reference to Fig. 3, can see the annual ring of heat-treated wood, can also see that the color of heat-treated wood is more black relatively.The heat treated research work of timber has been carried out some years in for example Finland, and with reference to aforementioned document.In this article, heat treatment process is the permanent process that changes of the physical property of timber, i.e. moisture and intensity, heat-insulating property etc.When timber was subjected to temperature more than 150 ℃, these variations can take place.The heat treatment wooden core member preferably has 350kg/m
3-500kg/m
3Between density.
The timber kind of the heat treatment section of core can be any kind of that is suitable for described purpose, is exemplified as the cork kind such as pine or dragon spruce.
The thermal effectiveness of timber depends on following a plurality of parameter:
Maximum temperature during the actual heat treatment and duration
Temperature gradient
Whole heat treated duration
The use of steam and consumption
Kiln run before the actual heat treatment
Timber kind and characteristic thereof
As mentioned above, the temperature that is higher than 150 ℃ for good and all changes the physics of timber and chemical attribute, and for example the pucker ﹠ bloat of the colour-darkening of timber, timber reduces and the equilibrium moisture content of timber improves.Find that also intensity reduces, but heat-insulating property strengthens.Heat treatment process is divided into warming up period, actual heat treatment phase and cooling cycle usually.In preheating and cooling period, the control temperature gradient is to avoid timber and excessively ftracture or to break.
Heat treatment reduces suction and reduces, and this durability and anti-deterioration to timber is favourable.Yet, this effect also reduce molded during the adhesion property of plastic material, therefore up to today, still think to be difficult to heat-treated wood is encapsulated in the plastics.
The expansion of heat-treated wood and contraction reduce, so reduced the risk that the plastic packets coating breaks.
The shortcoming of heat-treated wood is crooked and hot strength reduces 10%-30%, and timber becomes more frangible, but is surprised to find, according to the problem that does not have the intensity reduction in the frame construction of the present invention.
Fig. 4 and Fig. 5 schematically show the alternate embodiments according to frame construction of the present invention.Fig. 4 shows the viewgraph of cross-section of window frame side piece, and Fig. 5 correspondingly shows the viewgraph of cross-section of window sash.In Fig. 4 and Fig. 5, find out that in cross-sectional view the plastic packets coating that is surface course 103,203 forms of plastic material only covers the part on the surface of wooden core member 102,202.Surface course 103,203 comprises two groups, and at least two parts of every group are arranged on the basic facing surfaces of described core component in described two groups.As previously mentioned, between surface course 103,203 and core component 102,202, realized big adhesion, because plastic material is attached to heat-treated wood well.Yet,, also realized the safe separating of plastics and heat-treated wood by the so special surface layer part that is provided with.
