Description
- This application relates to the technical field of wood doors and windows, and particularly to a corner joint for wood doors and windows. The present application further relates to a wood door and an aluminium-clad wood window both employing the corner joint.
- Wood doors and windows are mainly referred to solid wood doors and windows and aluminium-clad wood doors and windows, and they both have a long production history around the world. Presently, European aluminium-clad wood windows are mainstream products, and are optimal among various kinds of doors and windows of different materials in aspects such as heat preservation, sound insulation, environmental protection, residential comfort, and etc. However, the European aluminium-clad wood windows has a complicated production process, and thus many parts require quality assurance, among which, the corner joint for doors and windows is a key factor influencing the qualities of wood doors and windows.
- At present, there are mainly three kinds of corner joints in the market, including a tongue and groove joint, a bolt joint, and a 45-degree dovetail joint. In the tongue and groove joint, the mating members are coated with glue and then are pressed by a press machine, and since the tongue and groove joint is a rigid connection, internal stress generated due to swelling and shrinkage of wood in response to climate changes is hard to eliminate, and thus the corner of the wood door or window is apt to crack over a period time. Further, this production process can only perform paint spraying, sanding and fastener installation after a door frame or a window frame is assembled, while the assembled door frame or window frame is large and heavy, therefore, the operation is difficult to perform, the working procedure is complicated, more requirements are imposed on the apparatus and the production cycle is long. The bolt joint can produce each mating member individually with a single timber, and perform paint spraying and sanding on the produced mating member and then assemble these mating members, thus the process is simple. However, there are still deficiencies in the bolt joint. The bolt joint has two connection manners, including a splice joint having complementarily configured ends and a flat-head dowel joint. In the splice joint having complementarily configured ends, two perpendicularly abutted timbers are spliced together at their mating ends, an outer profile of each mating end has multiple stepped shapes, and then the two timbers are fixed by a bolt, and an over positioning is caused due to too many contacting surfaces, and under the action of swelling and shrinkage of the timbers, a slit is apt to form at the junction of the complementarily configured ends. In the flat-head dowel joint, two perpendicularly abutted timbers are positioned at the junction thereof by a planar surface and a dowel perpendicular to the planar surface and are fixed by a bolt. Although the two timbers positioned by the dowel may be prevented from moving in the abutting plane even after undergoing many times of swelling and shrinkage, a slit may still form at the corner junction, where inclined surfaces are spliced, due to swelling and shrinkage of the timbers, and thus water seepage, dust accumulation and even fungi growth may be caused accordingly.
- In conclusion, a technical issue to be addressed by the person skilled in the art is to make the connection structure for wood doors and windows have a simple structure, being convenient to manufacture, have a high structural strength and a good weatherability.
- In view of this, an object of the present application is to provide a corner joint for wood doors and windows, which simplifies the connection structure of the wood doors and windows and also ensures the structural strength of the wood doors and windows, and improves the connection quality of at the corner of the wood doors and windows.

- Referring to
Figures 1 to 7 , a corner joint for wood doors and windows is provided according to an embodiment of the present application, and is referred to as a corner joint hereinafter for brevity. The corner joint includes afirst timber 1 and asecond timber 2, and an axis of thefirst timber 1 is perpendicular to an axis of thesecond timber 2. A firstinclined surface 101 and at least one position-fixing plate 102 are provided at an end surface of an end of thefirst timber 1. The firstinclined surface 101 is inclined with respect to the cross section of thefirst timber 1 and is perpendicular to a plane defined by the axes of thefirst timber 1 and thesecond timber 2. The cross section of thefirst timber 1 is a section perpendicular to the axis of thefirst timber 1. The position-fixing plate 102 is in parallel with the plane defined by the axes of thefirst timber 1 and thesecond timber 2. A secondinclined surface 201 and a position-fixingsurface 202 are provided at an end surface of an end of thesecond timber 2. The secondinclined surface 201 is configured to cooperate with the firstinclined surface 101 by abutting against the firstinclined surface 101. The position-fixingsurface 202 is configured to cooperate with a plate surface of the position-fixingplate 102 to fix the position of thefirst timber 1 with respect to thesecond timber 2. - In this corner joint, fixation is achieved by abutment of the inclined surfaces, which realizes the joining of grain broken surfaces of woods (a grain broken surface is a section perpendicular to the growth direction of wood fiber), and the joining strength is high. Further, the position fixing is achieved by using the position-fixing
plate 102 and the position-fixingsurface 202 which are in parallel with the plane defined by the axes of thefirst timber 1 and thesecond timber 2, therefore, the structure is simple, and the connection strength of the corner joint is further increased. Further, the position-fixing structure combining the inclining surfaces and the position-fixing surfaces can ensure the strength of the joining surfaces even in case of swelling and shrinkage, and a slit is not apt to form at the junction, thus the weatherability of the corner joint is improved. Furthermore, processes, like paint spraying, film coating or surface coating with wood may be performed on thefirst timer 1 and thesecond timber 2 before thefirst timer 1 and thesecond timber 2 are assembled and do not have to be performed after thefirst timer 1 and thesecond timber 2 are assembled, thus facilitating the installation and manufacture and shortening the manufacturing cycle. - Further, in this embodiment, an included angle between the first
inclined surface 101 and the cross section of thefirst timber 1 ranges from 30 degrees to 60 degrees. The firstinclined surface 101 is in cooperation with the secondinclined surface 201 by abutting against the secondinclined surface 201, and the sum of the included angle between the firstinclined surface 101 and the cross section of thefirst timber 1 and an included angle between the secondinclined surface 201 and the cross section of thesecond timber 2 is set to be equal to 90 degrees. - Still further, the included angle between the first
inclined surface 101 and the cross section of thefirst timber 1 ranges from 40 degrees to 50 degrees, to allow the included angle between the firstinclined surface 101 and the cross section offirst timber 1 to be approximate to the included angle between the secondinclined surface 201 and the cross section of thesecond timber 2, thus achieving the joining of the grain broken faces of the woods and obtaining a better strength of the corner connection. More preferably, the included angle between the firstinclined surface 101 and the cross section of thefirst timber 1 is set as 45 degrees, to be equal to the included angle between the secondinclined surface 201 and the cross section of thesecond timber 2, and thus the connection strength is optimum. - As shown in
Figure 2 , in this embodiment, an included angle at an end of the position-fixingplate 102 is a right angle, and the position-fixingplate 102 is a right-angled triangular plate. An end surface of the position-fixingplate 102 is in parallel with the cross section of thesecond timber 2, and the end surface of the position-fixingplate 102 is configured to abut against the end surface of thesecond timber 2. With this arrangement, the position-fixing area of the position-fixingplate 102 may be increased and also the structural strength of the position-fixingplate 102 may be improved. Of course, the included angle at the end of the position-fixingplate 102 may also be an obtuse angle or an acute angle. However, in the case of the included angle being set as an obtuse angle, the position-fixingplate 102 has a small position-fixing area; and in the case of the included angle being set as an acute angle, the position-fixingplate 102 has a structural strength less that in the case of the included angle being set as e a right angle. - Further, in this embodiment, the plate surface of the position-fixing
plate 102 is flush with a side surface of thefirst timber 1 which is perpendicular to the firstinclined surface 101. With this arrangement, when the corner joint is assembled, the position, where the firstinclined surface 101 is in contact with the secondinclined surface 201, is hidden within the position-fixingplate 101, which can better protect the abutting surfaces and improve the weatherability, and also obtain an aesthetic appearance. - Still further, the number of the position-fixing
plate 102 is one and the plate surface of the position-fixingplate 102 is flush with a side surface of thefirst timber 1 which is located inside the room. Of course, the number of the position-fixingplate 102 may also be two, three or more. The number of the position-fixingsurface 202 is equal to the number of the position-fixingplate 102, and in the case that multiple position-fixing surfaces and position-fixing plates are provided, the position-fixingsurfaces 202 are in cooperation with the respective position-fixingplates 102 to fix the position of thefirst timber 1 with respect to thesecond timber 2.
