For example, the thickness of the first strength layer 11 is 14mm, the thickness of the insulating layer 12 is 42mm, the thickness of the second strength layer 13 is 14mm, and the thickness of the first strength layer 11 and the second strength layer 12 accounts for 20%; or the thickness of the first strength layer 11 is 12.25mm, the thickness of the heat insulation layer 12 is 45.5mm, the thickness of the second strength layer 13 is 12.25mm, and the thickness ratio of the first strength layer 11 to the second strength layer 12 is 17.5%; or the thickness of the first strength layer 11 is 10.5mm, the thickness of the heat insulation layer 12 is 49mm, the thickness of the second strength layer 13 is 10.5mm, and the thickness ratio of the first strength layer 11 to the second strength layer 12 is 15%.

Taking the specification of the 70 series as an example, the standard coal can be saved by 250-300 kg per building in the heating period of one year. On the other hand, the mechanical properties of the window frame of this embodiment accords with the national standard requirement, and dimensional stability is good, and when effectively having avoided moist weather, the window frame is too tight to be opened, and when dry weather, the phenomenon that the window frame is too loose.
The heat-insulating layer 12 is a thermal treatment plate of Chinese white poplar treated at 175-185 ℃: (1) when the thickness proportion of the first strength layer 11 and the second strength layer 12 is 20%, the MOR is 62MPa, the impact toughness is 70 KJ/square meter, and the radial wet expansion rate is reduced by 6.7% compared with a Chinese white poplar plate with the same thickness; (2) when the thickness ratio of the first strength layer 11 to the second strength layer 12 is 17.5 percent, the MOR is 61MPa, the impact toughness is 75 KJ/square meter, and the radial wet expansion rate is reduced by 15.2 percent compared with a Chinese white poplar plate with the same thickness; (3) when the thickness of the first strength layer 11 and the second strength layer 12 accounts for 15%, the MOR is 65MPa, the impact toughness is 78 KJ/square meter, and the radial wet expansion rate is reduced by 21.2% compared with a Chinese white poplar plate with the same thickness.
The heat-insulating layer 12 is a heat-treated Chinese white poplar plate treated at 215-225 ℃, and comprises the following steps: (1) when the thickness proportion of the first strength layer 11 and the second strength layer 12 is 30%, the MOR is 63MPa, the impact toughness is 75 KJ/square meter, and the radial wet expansion rate is reduced by 17.3% compared with a Chinese white poplar plate with the same thickness; (2) when the thickness proportion of the first strength layer 11 and the second strength layer 12 is 27.5 percent, the MOR is 60MPa, the impact toughness is 66 KJ/square meter, and the radial wet expansion rate is reduced by 26.3 percent compared with a Chinese white poplar plate with the same thickness; (3) when the thickness of the first strength layer 11 and the second strength layer 12 accounts for 25 percent, the MOR is 58MPa, the impact toughness is 64 KJ/square meter, and the radial wet expansion rate is reduced by 31.8 percent compared with a Chinese white poplar plate with the same thickness.
In a preferred embodiment, as shown in fig. 2, the first strength layer 11 and the second strength layer 13 are formed by extending a plurality of chinese white poplar veneer strips, the heat-insulating layer 12 is formed by extending a plurality of chinese white poplar heat-treated veneer strips, and one of the joints of the first strength layer 11 and the second strength layer 13 does not overlap with the joint of the heat-insulating layer 12.
As a further preference, referring to fig. 1, the first strength layer 11, the insulating layer 12, and the second strength layer 13 form a composite profile body 10, the composite profile further includes a reinforcing strip 20 located at a side edge of the composite profile body, the reinforcing strip 20 is a chinese white poplar strip, and the reinforcing strip 20 is fixedly connected with the composite profile body 10 by gluing. The width of the reinforcing strip 20 is 15 cm-20 cm.
Through setting up the reinforcing bar at one side of composite section bar body to make the composite section bar of this application technical scheme mill when forming the structure that is used for the assembly, milling process department is the chinese white poplar lath all the time, and does not make the relatively weak heat preservation of mechanical properties expose outside.
Specifically, in this embodiment, an inward concave groove 14 is formed on one side edge of the composite profile body 10 along the length direction thereof, and a pair of outer side walls of the groove 14 are respectively an extension of the upper surface of the first strength layer 11 and an extension of the lower surface of the second strength layer 13, that is, the pair of outer side walls of the groove 14 and the upper surface of the first strength layer 11 and the lower surface of the second strength layer 13 form the same plane. A pair of inner side walls of the groove 14 are respectively located on the first strength layer 11 and the second strength layer 13. The reinforcing strip 20 comprises a reinforcing part 21 with the same thickness as the composite profile body 10 and an inserting strip 22 matched with the groove 14. After splicing and bonding, part of the first strength layer 11, the heat insulation layer 12 and part of the second strength layer 13 are bonded on the end face of the insert 22, and the improvement of the bonding strength and the structural stability of the structure is facilitated. The groove 14, the reinforcement 21, and the insert 22 are formed by milling. The structure is particularly suitable for manufacturing and processing the aluminum-clad wood window frame, the aluminum-clad wood window frame needs to be manufactured into a special-shaped structure on one side edge of the section bar through milling, the special-shaped structure is used for fixedly mounting the section bar of the aluminum structure, mounting glass and matching an inner window sash and an outer window sash, and the milling part is always a Chinese white poplar strip through the arrangement of the reinforcing strip 20, so that a heat-insulating layer with relatively weak mechanical property is not exposed outside.
Of course, the structure can be better suitable for manufacturing the window frame with a pure wood structure. Turning to fig. 1, when in a humid environment, because the first strength layer 11 has a higher wet expansion rate than the insulating layer 12, the pair of side walls of the groove 14 will be pressed more toward the reinforcing strips 20, and further, the point a will be pressed toward the point B by the tensile force of the insulating layer 12 on the reinforcing strips 20, thereby facilitating the tight fit of the sealing strip between the glass sheet and the window frame. While the first strength layer 11 has a greater shrinkage than the insulation layer 12 when in a dry environment, the sides of the insulation layer 12 limit the deformation of the reinforcing strips 20 so that the positions of points a and B can be maintained relative to each other. The same applies to the case of the second strength layer 13.
Example 2, example 2 differs from example 1 in that, referring to fig. 3 and 4, a rib 15 is formed on one side edge of the composite profile body 10 along the length direction thereof, and the upper surface and the lower surface of the rib 15 are respectively located on the first strength layer 11 and the second strength layer 13; the reinforcing strip 20 comprises a reinforcing part 21 with the same thickness as the composite profile body 10 and a slot 23 matched with the convex strip 15. The structure is particularly suitable for manufacturing and processing pure wood window frames. Turning to fig. 3, when in a humid environment, the wet expansion rate of the first strength layer 11 forming the convex strip 15 and the groove wall of the slot 23 are both larger than that of the insulating layer 12, the two parts are mutually extruded, and the point C is extruded at the point D due to the limitation of the insulating layer 12, thereby being more beneficial to the tight fit of the sealing strip between the glass sheet and the window frame. When the heat insulation layer is in a dry environment, the wet expansion rates of the first strength layer 11 part forming the convex strip 15 and the groove wall of the slot 23 are both larger than that of the heat insulation layer 12, the two parts are mutually extruded, the two parts are mutually limited and deformed, and the slot 23 is kept at the original position under the action of jacking and expanding of the heat insulation layer 12, so that the position of the point A and the position of the point B can be kept at the relative position. The same applies to the case of the second strength layer 13.
The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
