Description
Technical field
The present invention relates to a kind of attachment structure of section bar door and window, and it is related to the manufacture method of the structure, and in particular to a kind of wood moulding door-window section bar attachment structure and its manufacture method.
Background technology
All the time, the quality of door and window corner connection has very important effect to the overall quality of door and window.Gradually popular especially with the technology using section bar manufacture door and window, the corner bond strength of section bar door and window has prior effect to the total quality and durability of door and window.Current visible aluminum alloy doors and windows, Aluminum plastics door and window, PVC door and windows and wood moulding door and window all expose certain defect in corner with reference to upper, corner combines the reduction that not result in door and window service life not only closely, also results in doors and windows sealing deficiency and brings unnecessary heat consumption.Especially in the area that weather conditions are severe, because the pyrocondensation of material it is swollen, it is wet collapse inevitable with creep, door and window corner connects insecure untight problem and just displays.The corner connection of solid wood door and window is typically more firm, but " drying shrinkage bulking " phenomenon of timber is obvious, and timber has hygroscopic deformation, easily rotten disadvantage in wet condition.The solder technology that existing aluminum alloy doors and windows are used is not applied for the connection of hierarchy door-window section bar, and prior art generally can not ensure the bond strength of angle junction；Moreover, traditional solid wood door and window connection can be rotten because of corner bulking or corner, and then influences the overall performance of door and window.
Compound method is carried out with Wood-plastic material and timber and prepares door-window section bar, be expected to be solved from the angle of material the drawbacks described above of door and window product.But the wood moulding solid wood composite of hierarchy is not convenient to use, for erection of doors and windows brings difficulty, therefore the corner structure of a kind of quick for installation, material-saving and the novel wood-plastic door and window with higher-strength and sealing property is provided, as current letter technical problem to be solved.
The content of the invention
For above mentioned problem present in background technology, it is an object of the invention to provide a kind of wood moulding door-window section bar attachment structure and its manufacture method, with solve to occur during door-window section bar is manufactured for door and window because material is not convenient to use installation difficulty, because bonding strength is not high and fragile, because sealing property is not good energy consumption it is big, because the pyrocondensation of material is swollen and the wet collective effect for collapsing and the defect such as yielding.
