Definitions

  • 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 window and a wood door each using 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.
  • 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.
  • 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.
  • a tongue and groove 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.
  • 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 assembles these mating members, thus the process is simple.
  • the bolt joint has two connection manners, including a splice joint having complementarily configured ends and a flat-head dowel joint.
  • 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.
  • 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.
  • 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. Further, the load-bearing capacity is low since the weight of the door or the window is also born by the dowel.
  • connection structure for wood doors and windows have a simple structure, being convenient to manufacture, have a high structural strength and a good weatherability.
  • 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, is convenient to install and manufacture, 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.
