Frame combining structure and corner combining method of wooden door and window sash

Abstract

The invention relates to a frame combining structure of a wooden door and window sash. A door and window at least comprises a door and window frame or a door and window sash frame, wherein the door and window frame or the door and window sash frame is mainly formed by combining adjacent profile frame strips through corner combining devices on adjacent end surfaces. The frame combining structure is characterized in that connecting end surfaces of two adjacent profile frame strips are manufactured into 0-180 degree sections respectively, corner combining device positioning grooves are at least machined in the sections, after the adjacent profile frame strips are spliced, a space for accommodating the assembly corner combining device is formed in each spliced position, one half of the corner combining device is embedded and fixed in the positioning groove of the 0-180 degree section of one profile frame strip, the other half of the corner combining device is embedded and fixed in the positioning grooves of the 0-180 degree sections of the adjacent profile frame strips, the two halves of the corner combining device are connected through middle fasteners and fastening bolts to form the complete assembly corner combining device, and the two adjacent profile frame strips are closely and fixedly connected. The frame combining structure has the characteristics that the structure is simple, convenient to mount and firm to use, corner connection strength and sealing performance after corner combination can be effectively guaranteed, besides, the frame combination convenience can be increased, the production efficiency can be improved, and the like.

Description

technical field [0001] The invention relates to a frame structure of a wooden door and window, and belongs to the technical field of building doors and windows. Background technique [0002] At this stage, China is vigorously promoting energy conservation and emission reduction policies, and building energy conservation, as an important component of the overall energy conservation field, is playing an increasingly important role. The energy saving of doors and windows accounts for about 40%~50% of building energy saving. To improve the energy saving of doors and windows is to improve the building energy saving; wooden doors and windows are widely used in energy-saving buildings because of their good thermal insulation performance. [0003] The traditional wooden door and window sash is framed by groove and tenon connection. The overall process is relatively complicated and the matching accuracy is high. In the process of groove and tenon processing and corner assembly, mor...

Problems solved by technology

[0003] The traditional wooden door and window sash is framed by groove and tenon connection. The overall process is relatively complicated and the matching accuracy is high. In the process of groove and tenon processing and corner assembly, more processing equipment is used, the cost is large, and the accuracy control is difficult; When the angle is set at 45°, it is realized by using the round mortise rod and dovetail tenon. However, because the dovetail is made of nylon and its own structural reasons, it is difficult to achieve the overall strength of the angle after assembling the groove tenon. The strength of the group corners, and there will be some joints that will not be tightly sealed over time at some joints, resulting in water seepage, mildew, etc.
