Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a method of manufacturing a window frame,

The present invention relates to a method of manufacturing a window frame with improved thermal insulation, which can be commonly used for windows of various constructions such as general windows, glass walls in buildings, and tempered glass doors. More specifically, The mainframe has two grooves formed on its upper and lower sides so that the mainframe can be divided into left and right members when cut. The grooves are formed in the grooves on one side of the main frame, and the grooves are filled with the heat- It is possible to provide a method for manufacturing a frame for a window which is capable of manufacturing a heat insulating frame having high durability and heat insulation because it is manufactured by assembling and assembling an auxiliary frame of a stainless steel structure on both sides of a main frame .

Most of the frames for window frames used in windows with various configurations such as general windows, glass walls inside the buildings, and tempered glass doors are mostly made of aluminum or synthetic resin using a single material. However, such a structure has a problem of low thermal insulation due to high thermal conductivity, and in particular, there is a problem that dew condensation occurs in the winter season.

In recent years, as a means for solving such problems, a frame for a window frame is divided into two, and mutual connection is made by using a connecting member of different material, thereby achieving the object of improvement of heat insulation and prevention of condensation phenomenon.

As a representative example, a window frame for preventing condensation of a folding door and a method for manufacturing the same is disclosed in Korean Patent Laid-Open Publication No. 10-2013-007458 (Apr. 3, 2014). This is because the inside of the frame is hollow, The slits are formed on both side walls of the slit, and a heat insulating member is injection-molded between frames provided with a joint member having a space portion inside the slit, thereby making it possible to securely fix the conical member while preventing condensation. And the first and second slits are respectively formed on both sides of the first slit and the second slit, and a first and a second coupling members having a first space and a second space, respectively, inside the first slit and the second slit, Providing a base frame;

2) filling the melt in the first space part through the first slit and cooling to form a first heat insulating member;

3) cutting the first joint member and the second joint member to form a cut-off portion, respectively;

4) sealing the cut-off portion of the second coupling member; 5) filling the inside of the second space with a melt and cooling to form a second heat insulating member;

6) opening the disconnecting portion of the second coupling member.

However, in the above-described technique, it is recommended to perform taping of the bottom surface of the second joint member in the step (4), and there is no frame structure capable of satisfying the characteristic that the liquid azon is vulcanized after injection, The productivity of the produced frame is inevitably deteriorated.

Another example is a heat insulating frame for a window of Korean Registered Patent Application No. B1-1,144,649 (May 05, 2012.), which has a connection recess formed at one side thereof, A reinforcing frame on which an azon injection port is opened at the tip of the submerged trunnion; An azine insulator filled in the azon filler chamber; A heat conduction cut-out portion formed at the center of a closed face opposite to the azon inlet for cutting through a cutting operation after the installation of the azon heat insulating material; A pair of outer frames continuously installed to cover one inner surface of the connection concave portion and an outer surface of the reinforcing frame; And a vertical insulating frame made up of a silicon joint portion provided between the joint surfaces of the pair of outer frames facing each other. In this case, the reinforcing frame is filled with azon heat insulating material in the center of the inner and outer sides The upper and lower surfaces of the azon filler enclosing the azon insulator are respectively cut so that the heat conduction path between the room and the inside and outside is completely blocked to effectively prevent the condensation phenomenon and reduce the heat loss to the outside, There is a problem in that the heat insulating property is limited and the durability is deteriorated by a constitution in which the two side constituent members are connected by one heat insulating material constituting the azon.

As a result, there has been a demand in the industry for a frame of a new structure which is improved in heat insulation by using two or more insulation materials while satisfying excellent appearance and heat insulation.
