In particular, the present invention installs a strip that expands by heat at the connection between the window frame and the window or between the window frame and the glass window, so that when a fire occurs, the space in which the thermal expansion strip is installed is filled to prevent the fire from spreading to other spaces. However, it is an object of the present invention to provide aluminum fire protection windows and doors capable of preventing deformation of windows.

In addition, since aluminum windows and doors have a melting point of 660℃ due to the characteristics of aluminum alloy, they were recognized as an unsuitable material for fire windows that must withstand temperatures of 850 ℃ or higher, and were not even reviewed as fire window materials. Since it is made with a bending method, the shape is not diverse and the workability and appearance are not beautiful. It is an object of the present invention to provide aluminum fireproof windows and doors capable of implementing various colors through paint and anodizing as well as possible.

A fireproof window according to the present invention for solving the above object applies an aluminum alloy extruded material, and in a window installed to open and close a window inside a window frame, the window frame constituting the window or at least the inside of the window frame It is characterized in that it is configured by installing a thermal expansion member that expands by heat on one side.

Preferably, the thermally expandable member is installed on each of the four window frames constituting the window.

A coupling groove into which the thermally expandable member is inserted and coupled may be further formed in the window frame.

The thermally expandable member is preferably made of a thermally expandable refractory resin composition.

In the fireproof window according to the present invention, a thermal expansion member is installed inside the window frame so that when a fire occurs, it expands and fills the inside of the frame to reinforce the strength of the frame to prevent deformation of the frame, thereby creating a gap between the frames. It has the effect of preventing the flame from spreading to neighboring spaces.

In addition, by overcoming the perception that it is impossible to manufacture aluminum fire windows by structurally supplementing the limitations of aluminum, aluminum alloy extruded materials are applied to fire windows made of steel and stainless steel, which are not diverse in shape and color and have poor workability due to heavyness, and are free in shape. Painting or anodizing has the effect of providing a fireproof window with a beautiful appearance and light weight that is easy to process and install.

In describing the present invention, if it is determined that a detailed description of related known technologies may obscure the gist of the present invention, the detailed description will be omitted.

The present invention installs a thermal expansion member that expands by heat at the connection between the window frame and the window or between the window frame and the glass window to reinforce the strength of the frame by expanding in the event of a fire, thereby preventing the frame from being deformed, so that the flame spreads to the neighboring space. can prevent

The fire protection window according to the present invention can be applied to a conventional casement window or curtain wall, as shown in FIGS. 1 and 5, and is installed in a window installed to open and close the window inside the window frame.

That is, the present invention installs a thermal expansion member 10 that expands by heat on at least one side of the window frame 100 constituting the window or the frame of the window 200, so that when a fire occurs and heat is applied to the window, the As the thermally expandable member 10 expands and fills the inside of the frame constituting the window, the strength of the frame constituting the window is reinforced to prevent the frame from being deformed by the flame, thereby preventing the frame from being deformed by the flame. There is no gap between the frame constituting the window and the frame constituting the window frame, so flame can be prevented from propagating to neighbors.

The thermally expandable member 10 may be installed in a vulnerable part of the frame constituting the window or window frame that is relatively easily deformed by an external force, and is particularly installed in a part that is greatly affected by flame when a fire occurs. It can be.

As shown in Figs. 2 to 4 and Figs. 6 and 7, the thermally expandable member 10 is preferably installed on each of the four window frames constituting the four sides of the window frame.

The thermally expandable member 10 can also be installed on a window frame constituting a window frame, but in the case of a window frame, since it is fixed to a wall constituting a building, it is not easily deformed, so there is no need to install it.

Of course, the thermally expandable member 10 can also be installed on the window frame, and when installed on the window frame, it can be installed inside the space facing the wall. However, as described above, the window frame is fixed to the wall structure and is deformed by flame. Possibility is low, and when the thermal expansion member is installed even on the window frame, it is preferable not to install it on the window frame in order to prevent an increase in construction cost due to the excessive use of materials when constructing the window.

As shown, the thermally expandable member 10 is installed inside the window frame constituting the window to prevent the thermally expandable member from being exposed to the outside of the window and damaging the aesthetics, and the thickness or width thereof is the window frame when expanded by heat. It is installed to the extent that it can fill the internal space of the

The thermally expandable member may be made of a thermally expandable refractory resin composition, and the thermally expandable refractory resin composition may be selected from commercially available ones.

As shown in FIG. 4, it is preferable that a coupling groove G into which the thermally expandable member is fitted is further formed in the window frame.

As shown in the figure, the thermal expansion member may be manufactured in the shape of a plate material strip and installed on one side of the inner wall of the frame, but at this time, the construction may be cumbersome as it must be fixed using an adhesive tape or adhesive, In order to solve it, it can be installed more easily by forming a coupling groove (G) that can be coupled by inserting a strip-shaped thermal expansion member inside the frame so that it can be inserted.
The thermally expandable member 10 is installed on the window frame, and it is preferable that the coupling groove formed on the outer wall facing the window frame of the window frame and the edge of the plate glass inserted into the window frame correspond to each other.
