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

Abstract

A frame structure of wooden doors and windows: the doors and windows at least include door and window frames or door and window frames, and the door and window frames or door and window frames are mainly connected by adjacent profile frame strips through corner joints on adjacent end faces It is characterized in that the connecting end faces of the two adjacent profile frame strips are respectively made into 0~180° cross-sections, at least positioning notches for corner sets are processed on the 0~180° cross-sections, and After the adjacent profile frames are spliced ​​with each other, a space is formed at the joint to accommodate the assembled corner set, half of which is embedded and fixed in the positioning notch on the 0~180° section of a profile frame, and the other Half of the corner set is embedded and fixed in the positioning notch on the 0~180° section of the adjacent profile frame, and the two halves of the corner set are connected by the middle fastener and fastening bolt to form a complete assembled corner set , and tightly connect two adjacent profile frames; it has the advantages of simple structure, convenient installation, firm use, can effectively ensure the strength of the corner connection and the sealing after the corner is assembled, and can increase the convenience of the frame , Improve production efficiency and other characteristics.

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, more ...

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.
