Description

TECHNICAL FIELD [0001] The present invention relates to a method of manufacturing a stainless steel insulating window frame,

The present invention relates to a stainless steel heat insulating window frame installed in a building and more particularly to a heat insulating window frame provided between an inner stainless steel frame and an outer stainless steel frame and a glass window fixed to the heat insulating module, To a stainless steel heat insulating window frame which firmly bonds the stainless steel frame and the heat insulating module while the heat transfer is blocked.

2. Description of the Related Art Generally, a window (window) refers to various windows or doors installed in an opening of a window or an entrance to block the inside of a building from the outside, and includes a window frame for forming an outer frame, And is configured to be coupled to the frame. The window frame according to the related art is made of aluminum or stainless steel, and a lot of heat insulation material is applied between the frames for heat insulation between the outdoor side and the indoor window frame.

Generally, a window includes a window frame that forms an outer frame, and a window that is opened and closed by being coupled to the window frame, and a closed window that is not opened or closed is installed together at the upper portion, one side, or the corner portion to improve the heat insulating performance. The aluminum project and the pull-down window frame chassis structure improved in the heat insulation performance of Korean Patent Registration No. 10-0975604 (published on Aug. 8, 2010) and the Korean Patent Registration No. 10-1243416 There is an aluminum window for improvement of the insulation performance of the announcement on March 13, 2013, which consists of a window frame made by extruding aluminum, and an aluminum window frame is covered with insulation for insulation between the inside and outside of the room.

However, aluminum windows of such prior art aluminum windows have a high thermal conductivity of 196 kcal / 占 폚, which results in high heat loss, insufficient heat insulation, insufficient heat insulation performance, and low scratches.

Recently, a window frame made of stainless steel material rather than aluminum material has been developed, and it is generally installed at a doorway or a floating population, such as a window window of a building or a window of a lobby. Such a window frame made of stainless steel is usually formed by using a roll forming machine or the like, so that machining and formability are much less than aluminum materials.

However, the aluminum window of this prior art has a high thermal conductivity of 196 kcal / 占 폚, which results in high heat loss, insufficient heat insulation, insufficient heat insulation performance, and low scratches due to low hardness.

In recent years, stainless steel window frame made of stainless material rather than aluminum material has been developed and used. In addition, a stainless steel window frame has been used for insulation between the inside and outside of the room. As a prior art having such a window frame made of stainless steel, there is a stainless steel window frame having a heat insulating function of Korean Patent Registration No. 10-1217213 (published on Dec. 31, 2012).

Further, there is a problem that the connection between the heat insulating member and the stainless steel frame is not perfect and a space exists between the heat insulating member and the frame.

The present invention aims at improving the heat insulating performance by making the connection between the heat insulating member and the stainless steel frame complete, bringing the heat insulating member and the frame into close contact with each other, and preventing the space therebetween.

It is another object of the present invention to provide a stainless steel heat insulating window frame in which the interval between stainless steel frames can be adjusted so that the heat insulating members having different lengths are selectively installed between the inner and outer frames to correspond to the glass thickness .

The upper surface 110 is open to communicate with the inside and outside, and the opposite open end of the upper surface has a bent portion 115 bent inward. The lower surface has an upper surface A first step of providing a heat insulating module (100) having a protrusion (125) protruding inward at a position corresponding to a bent part of the heat insulating module (100); A second step of filling the interior of the metal frame with a heat insulating material; A third step of cutting between the bottom projecting portions of the metal frame; A fourth step of providing a stainless steel frame 200 having a square cross section and having a bending connection part 220 which is open at one side of the side to communicate with the inside and outside and whose open end opposite to the side is bent outward; A fifth step of forming a plurality of first fastening holes 250 at predetermined intervals along the longitudinal direction on the bent fastening part; A sixth step of arranging the metal frame between the bent fastening portions; And a seventh step of joining the stainless steel frame and the heat insulating module by screwing the screws into the fastening holes.

A heat insulating member 300 having insertion slit grooves 350 formed on both sides thereof is provided and a plurality of second fastening holes 360 are formed at both ends of the heat insulating member along the longitudinal direction at the same intervals as the first fastening holes And then inserting the bending coupling part 220 into the insertion slit groove.

The stainless steel heat insulating window frame according to the present invention improves the dimensional accuracy by firmly attaching the stainless steel frame and the heat insulating module in tight contact with each other, and the heat flow of the outside air transmitted through the frame is surely blocked by the heat insulating material.

In addition, the stainless steel heat-insulating window frame according to the present invention can be manufactured by installing heat-insulating modules having different widths and heights of the heat-insulating modules between the frames and matching the dimensions of the glass windows provided between the frames, The spacing between frames can be adjusted and the spacing between frames can be easily selected and inserted in various thicknesses in the field.

In addition, the stainless steel heat-insulating window frame according to the present invention is advantageous in that the interval between the inner and outer frames is adjusted to correspond to the thickness of the glass to shorten the construction time, thereby improving the cooling and heating efficiency, cost reduction, have.
