With the recent increase in the number of casualties caused by fires in buildings, the interest in reducing the spread of fires in buildings and securing the stability of evacuation is increasing. It is a fire prevention device of a building, and it has a fire wall, a fire shutter, a fire door, etc., and is installed in various places, such as a staircase part of a building, the part of the hallway or the hoistway of an elevator, or the floor floor part in the generation of a multi-storey apartment house. Fire prevention devices are important elements in buildings for evacuation or evacuation because they prevent the spread of flames and smoke during a fire.

In general, the fire protection device is made of a flame-retardant material that does not catch fire, such as steel sheet, and the inside is provided with a material having a low heat transfer coefficient (for example, polyurethane foam). By the way, since the material used for the conventional fire prevention apparatus is opaque, it is a case where it is comprised by the form which does not ensure the visibility which can observe the other side.

In order to secure the visibility, it is possible to install a fire protection glass having a heat shield function of a certain size or more. In general, the fire protection glass may be formed by inserting a plurality of sheet glass by using a spacer, inserting the heat shielding resin in the hollow layer between the bonded glass panes.

However, when the fire glass is formed using a plate glass of a large standard, the weight of the fire glass itself is excessively increased, so that the load of the fire glass is increased. In such a case, the strength of the frame supporting the fire protection glass is not sufficient to support the load of the fire protection glass, so that the bonding force between the frame and the fire protection glass is remarkably degraded, which may be vulnerable to vibrations or shocks generated from the outside, and the workability is also remarkably degraded. . In addition, the heat shielding performance of the frame itself is dropped, heat is not transferred to the fire protection glass when a fire occurs, but heat is easily transferred through the frame surrounding the fire protection glass, so that the fire protection performance of the fire protection device is inferior.

Therefore, there is a need to provide a frame that can overcome these problems.

Embodiments disclosed herein may provide a frame having excellent heat shielding properties and mechanical strength by configuring and separating the inner space of the heat shielding frame into an outer frame and an inner frame and arranging a fireproof material therein. . In addition, by using the outer frame and the support frame can be easily coupled to the fire protection glass to the heat shield frame.

To support, the support frame is fixedly coupled to the first outer frame.

In the manufacturing method of the frame for fixing the fireproof glass according to the present disclosure, the opening of the second outer frame is caught on the locking jaw of the first outer frame having the locking step bent in both outward directions of one side having an opening. Comprising a step of coupling the contact surface of the first outer frame and the second outer frame, Inserting the first inner frame into the interlocked first outer frame and the second outer frame in the vertical and horizontal directions Supporting the outer frame and the second outer frame, fixing the contact surfaces of the first inner frame and the first outer frame and the second outer frame to each other, and the first outer frame, the second outer frame, and the supporting frame Fixing the support frame to the first outer frame to support it together.

According to various embodiments of the present disclosure, by providing a structure that combines the outer frame and the support frame provides a heat shield frame that is very easy to combine and detach the fire protection glass. Such a heat shield frame can provide increased strength to prevent deformation or breakage of the fire protection glass due to high heat in the event of a fire.
