Description

[0001] The present invention relates to a bracket for fixing a window frame,

The present invention relates to a bracket for fixing a window frame, and more particularly, to a bracket for fixing a window frame that can be easily assembled and installed, stably supports the load and wind pressure of a window frame and prevents condensation, For example.

Generally, apartment buildings and complex buildings are equipped with living rooms and isolated veranda for insulation and soundproofing, or they are widely used as a living room or an office space by expanding a veranda space.

However, since most of the exterior walls of the veranda are constructed to be thick enough to support the window sill containing the double glazing, it is necessary to expand the veranda and install multiple windows on the outside walls of the veranda for insulation and sound insulation.

When a quadruple is installed on the outer wall of the veranda which is made to fit the duet, the width of the window frame is wider than the outer wall of the veranda, and a separate bracket is installed at the bottom of the outer wall of the balcony to support the window frame.

The brackets installed on the outer wall of the veranda are generally formed of a metal or T shape and the upper horizontal portion is fixed to the lower end of the window of a quadruple installed on the outer wall of the veranda, Such as an anchor bolt.

For example, Korean Patent Laid-Open No. 10-2010-0044971 entitled " Window frame fixing bracket ", Registered Patent No. 10-1163094, "Condensation preventing pad for T- bracket ", and Japanese Patent Application Laid-Open No. 10-2014-0002481" A window bracket having an effect, and a publicly-known utility model No. 20-2015-0003919 "a dew condensation preventing member for use in a hardware bracket for a window" have been proposed.

Conventional techniques are those in which a separate heat insulating material or anti-condensation pad is interposed in a vertical part of a metal bracket that is in contact with an outer wall of a veranda, or a vertical part or a whole of a metal bracket is coated with a PVC material.

In the case of the metal bracket having a separate heat insulating material or anti-condensation pad on the vertical part, cold air is transferred to the horizontal part attached to the bottom of the window, thereby causing condensation and deteriorating heat insulation efficiency. In the case of the metal bracket, the preprocessing process for coating is very complicated, resulting in a low productivity and a low thickness of the coating of about 1 mm to 3 mm.

In addition, Korean Patent Laid-Open No. 10-2012-0004659 (published on Jan. 13, 2012) "Method of manufacturing a bracket for fixing a window frame using a metal plate drawing process and bracket for fixing a window frame" increases the durability of a metal bracket as shown in FIG. The side frame reinforcing pieces are formed by bending and protruding the entire sides of both side edges of the side receiving portion fixed to the wall of the window frame to support the lifting force and the pressing force due to the wind pressure, The bending state of the connection portion of the upper support portion and the side wall reinforcement pieces is unstable during the processing, so that it is difficult to manufacture the upper support portion and the side wall reinforcement pieces in an orthogonal state and the bending protruded sidewall reinforcement pieces hinders close contact when the heat insulating material is attached. So that the effect of heat insulation is deteriorated.

As shown in FIG. 8, the bracket of the metallic material without the heat insulating effect conveys the outside cool air as it is to the room as it is, thus causing condensation and lowering the heat insulation efficiency.

Korean Patent Publication No. 10-2010-0044971 (published on May 3, 2010) Korean Registered Patent No. 10-1163094 (issued on July 5, 2012) Korean Patent Publication No. 10-2014-0002481 (published on April 1, 2014) Korean Utility Model Publication No. 20-2015-0003919 (issued October 27, 2015) 5) Open Patent No. 10-2012-0004659 (2012.03.13. Open)
