The present invention relates to a curtain wall project window insulation structure, and in particular, in a metal curtain wall project window structure, by blocking the gap between the glass panel and the window frame frame of the metal project window discharged to the outside, the heat from the outdoors is transferred to the room through the gap It is composed of insulating material to minimize inflow and block heat conduction to the curtain wall frame side, so it can greatly improve the insulation performance, and also shield the gap between the window frame frame and the indoor curtain frame with a plurality of gaskets in the closed state. It relates to a curtain wall project window insulation structure whose structure is improved so that the sealing properties can be improved.

In general, as construction technology develops, structures such as sliding windows are gradually disappearing from the walls of various buildings, especially high-rise buildings, and tempered glass walls ( Curtain wall: We are installing and constructing a curtain wall.

In this way, when part or all of the exterior wall of a building is constructed with double-glazed glass or tempered glass, the construction is carried out after installing a support frame such as a curtain wall fixed to the building structure using a fixing member in the vertical and horizontal directions, and then the support frame The construction is performed by providing a fixing member capable of fixing the laminated glass or tempered glass to the outer wall of the building structure by fixing the laminated glass or tempered glass to the outer wall of the building structure.

In addition, windows are installed at predetermined positions on the exterior walls of the conventional building to be opened and closed for ventilation into the building, and double-layer glass or tempered glass can be fixed to these windows.

As modern buildings become taller and more densely populated, it is desirable to use aluminum with high strength, less construction, excellent durability, and a higher ignition temperature than conventional plastic materials in a situation where the size of windows must also increase according to the trend of placing importance on light and view. However, the aluminum material has a disadvantage in that the thermal conductivity is high and the loss due to convection is large. Most of the factors that degrade window performance are due to heat loss from metal frames such as aluminum.

As a prior art related to the existing project window, according to Korea Patent Publication No. 10-921654 "Project window" (registration date: 2009.10.07), the window frame fixing the glass is composed of one, and the thermal insulation performance is improved by the heat conduction of the metal. There was a problem with falling.

In addition, when the window frame of the conventional project window does not have a separate reinforcement means, when the window frame is opened and closed, there is a problem that the window frame is easily twisted or bent due to the weight and opening and closing shock of the double-layer glass or tempered glass.

It is coupled to the front end of the frame and has an inner space and is made of a synthetic resin material, and is inserted into the heat insulation support at the portion where the heat insulation support is connected to support the heat insulation support, and includes an L-shaped insulation connecting member.

In addition, when installing multiple thicknesses of double-layer glass or tempered glass, the conventional project window has a problem in that the structure of the door frame has to be changed because the gap between the door frame and the window frame is narrowed, so compatibility is very poor.

In addition, existing project windows easily conduct heat due to the structural characteristics of the metal curtain wall. Since there is a possibility that the heat from the outside can be easily conducted into the room through the
