The following comparisons are made:
as shown in fig. 1, the conventional bridge-cut aluminum alloy section adopts a nylon + 25% chopped glass fiber heat insulation strip, and because the nylon + 25% chopped glass fiber heat insulation strip has low strength, the nylon + 25% chopped glass fiber heat insulation strip must be tightly connected with the aluminum alloy section to bear force jointly, so that the aluminum alloy section and the nylon heat insulation strip must be engaged with each other by tooth, and the nylon heat insulation strip cannot be independently framed. When the temperature difference is generated indoors and outdoors, the window can only be realized by the deformation of the nylon heat insulation strip when the window is deformed cold and hot. When glass and hardware are installed, the outdoor aluminum alloy and the indoor aluminum alloy are stressed simultaneously, and the heat preservation performance is poor.
As shown in fig. 12, during thermal expansion, the expansion of the outdoor decorative profile is much larger than that of the core material, the outdoor decorative profile slides in the slot along the length direction of the slot, and expands in the width direction of the slot, and during thermal expansion, because the heat transfer coefficient is large, the temperature of the outdoor decorative profile rapidly rises and the length of the outdoor decorative profile rapidly increases when sunlight is directly irradiated in summer, and the frame formed by the outdoor decorative profile rapidly expands.
As shown in fig. 13, the cold shrink time state: the principle is the same as that of thermal expansion and the deformation direction is opposite.
As shown in fig. 14, the outdoor decorative profile and the core material of the present invention employ a semi-movable clamping assembly, the rolling rib has no engaging teeth, and the clamping groove and the cantilever clamping end have a certain gap in the width direction of the clamping groove, so that when a temperature difference occurs between the indoor and outdoor, the outdoor decorative profile and the core material can slide a small amount in the width direction of the clamping groove when the whole window is contracted by heating or cooling, thereby preventing cracks at the splicing position of the window and stress deformation of the profile, which is not achieved by the conventional large bridge-cutoff window system.
Fig. 15 and 16 are movement state diagrams of outdoor side decorative section bars under the expansion and contraction states.
As shown in fig. 15, during thermal expansion, the expansion of the outdoor decorative profile is much greater than that of the core material, the outdoor decorative profile extends, and the outdoor decorative profile slides in the slot along the length direction of the slot and expands in the width direction of the slot.
As shown in fig. 16, the deformation principle is the same as the thermal expansion when cooling, and the decorative section bar moves in the opposite direction.
As shown in fig. 14, the core material disclosed by the present invention has cantilevers and can be independently assembled into a frame, and when a temperature difference occurs between the inside and the outside of a room, the cantilevers on the core material can also be deformed, thereby preventing cracks at the joint of a window and stress deformation of a profile. Compared with nylon, the core material can be independently framed, so that the glass and hardware of the broken bridge window system are jointly supported by the core material and the indoor decorative section, the end part of the rolling rib of the outdoor decorative section is smooth and does not have teeth, and the outdoor decorative section can longitudinally move along the length direction of the clamping groove when the outdoor decorative section expands with heat and contracts with cold.
Fig. 17 and 18 are diagrams showing the state of stress applied to and deformation of the outdoor decorative profile on the core material cantilever when the outdoor decorative profile expands with heat and contracts with cold.
As shown in fig. 17, during thermal expansion, the expansion of the outdoor decorative profile is far greater than that of the core material, the outdoor decorative profile slides in the slot along the length direction of the slot, and expands in the width direction of the slot, so that the cantilever on the core material deforms, the ratio of the height to the thickness of the cantilever is large enough, the surface of the reinforcing material in the cantilever contains a fiber fabric, and the surface weight of the fiber fabric is 30-1200 g/m2Therefore, the transverse strength and the allowable deformation of the cantilever perpendicular to the single fiber direction are larger than the bending stress and the failure deformation generated by the deformation of the cantilever caused by the decorative section bar, and the core material is not damaged or permanently deformed.
As shown in FIG. 18, the deformation direction is opposite to that of the expansion mechanism in the cold contraction state.
As shown in fig. 19, the core material disclosed in the prior art large bridge-cutoff door and window patent can be framed, but does not have a cantilever, and cannot be deformed during cold and hot shrinkage, and the window joint is cracked and the profile is also deformed. And because the core does not have the cantilever, because the different straightness accuracy and the degree of twist of two kinds of materials, the core is blocked easily with the aluminum alloy cross-under when, and can not wear into.
