Description

Structure of window frame to support fireproof glass window in case of fire}

The present invention relates to the structure of a window frame for supporting fire prevention glass windows (double glazing) installed in system windows in the event of a fire, which can strengthen the fire prevention function by supporting fire prevention glass windows (double glazing) installed in system windows for a long time, in more detail. In the event of a fire, the frame, insulating guide bar, insulating cap bar, and finish cap are made of aluminum and insulating material and are relatively weak against heat, so to prevent deformation, steel reinforcement, plate, and '⊃' type bolt washer are bolted together. Then, straps that expand by heat are installed between the frame and the reinforcement, and on the inside and outside of the insulating guide bar. Magnesium boards are additionally installed on the inside and outside of the insulating guide bar, and the inside and outside of the fire glass are caulked with directional expansion foam seals to prevent fire. This relates to the structure of a window frame for supporting fire-resistant windows that can minimize deformation of the window due to heat by supporting it for a long period of time and prevent flames and smoke from spreading to the outside.

In general, system windows are windows designed and constructed using cutting-edge technology and computer systems. They simultaneously satisfy crime prevention, soundproofing, insulation, durability, and water resistance, and perform perfect window functions with efficient ventilation, opening/closing operation, and minimal space occupancy. Insulation emphasized in system windows is achieved by applying double-layer glass to block solar radiant heat from outside, prevent leakage of cooling and heating heat generated indoors, increase thermal efficiency, and block ultraviolet rays. Installed at the tip of the frame, The guide bar and finishing cap are replaced with a material with insulation performance to block external air and insulate, but the insulation function constructed by the fire glass, frame, guide bar, cap bar, and finishing cap of the system window is installed because the insulation efficiency is insufficient. In the field, there is a demand for system windows with additional insulation performance, frame strength reinforcement, and fire protection functions that can be constructed with a thermal transmittance (W/㎡K) that meets the insulation performance standards of energy-saving eco-friendly housing construction standards.

In addition, the performance evaluation standards for fire-retardant glass according to the Building Act (Article 52) and the Rules on Standards for Building Escape and Fire-proof Structures (Article 24) are KS F 2845 (Fire-resistance test method for glass compartments) 7.1-b. ), c), and the test results have strengthened the regulations that ensure fire resistance performance for more than 20 minutes (approximately 800°C) without insulation. The regulations have been strengthened to ensure that the structure of windows and doors that support fire-resistant glass in the event of a fire is not only strong and insulating. In addition, strengthening the fire protection function emerged as an essential requirement.

Prior art regarding the structure of conventional windows for fire prevention and insulation includes Publication Patent No. 10-2020-0069673 (Fire Prevention and Insulation Windows), Registered Patent No. 10-2345622 (Fire Prevention and Insulation Windows), and Registered Patent No. 10- No. 2483054 (aluminum fireproof window with flame and smoke blocking structure) was presented.

The first published patent includes a fireproof window provided on the outdoor side to prevent fire from spreading indoors in the event of a fire, and an insulating window provided on the indoor side to block heat transfer from the outside air, and the fireproof window is provided at the bottom. The roller is fitted into the window frame to support and slide the window glass provided at the top, and is a fire-resistant frame with non-combustible and fire-resistant functions. A fire-resistant glass is installed between and at the bottom of the fire-resistant glass and the fire-resistant frame, which is fitted into each corner of the fire-resistant frame. It is a structure that includes a 'ㄷ' shaped insertion and fixing member whose ends are inserted from both sides to stably fix the fire glass.

The second registered patent refers to a window frame that fixes glass and has a plurality of compartments formed inside, a window frame that supports the window frame and has a plurality of compartments formed inside, and is installed in at least one of the internal compartments of the window frame or window frame. A window support member that prevents deformation or separation of the window frame and the window frame due to high temperature in the event of a fire, and at least one installed on one side of the space formed when the window frame and the window frame are combined to release extinguishing substances due to high temperature in the event of a fire. The window support member, which includes a solid fire extinguishing member, is a fireproof expansion material that expands in volume above a certain temperature to support the inside of the window frame and window frame and blocks the spread of flame generated in the event of a fire, and is inserted so that the outer surface supports the inner wall of the compartment. It is at least one of a hollow metal core material or a fireproof perfusion material that is accommodated in the hollow part of the metal core material to support the metal core material and absorb heat generated in the event of a fire, and the glass has an end inserted into the window frame to prevent it from being removed in the event of a fire. The surrounding metal bracket is screwed and fixed to the metal core inserted into the window frame, and the contact surface between the end of the glass and the metal bracket is interposed with fire-resistant fiber insulation to prevent the glass from being damaged by heat transfer in the event of a fire. .

The third registered patent is that the thermal expansion member is installed in the window frame, and the thermal expansion member in the shape of a plate strip with a cross-section protruding to one side is installed in a groove-shaped coupling groove formed on the outer wall opposite to the window frame of the window frame, and is installed in a horizontal groove. The strip is a structure installed in the area where the edge of the plate glass that is inserted into the window frame corresponds.

The first published patent refers to a fire-resistant window installed by inserting a fire-resistant glass into a fire-resistant frame on the outdoor side using a fixing member and a setting block, and an insulating window installed on the indoor side to provide fire protection and a fire-resistant window. Since it is formed as a basic subsidiary material for installing glass, there is a problem in that it cannot perform the performance related to fire glass according to the rules regarding building codes and standards for evacuation and fire prevention structures of buildings.

The second registered patent refers to the fact that the glass is supported by a metal core and a metal bracket filled with fire-resistant expansion material and fire-resistant perfusion material in the compartment of the window frame and the window frame, and a solid fire extinguishing member is installed in the space formed when the window frame and the window frame are joined. The structure is designed to block flame transmission through the window frame and glass, and the joint area between the window frame and the window frame is joined by a gasket that is weak against heat, so the support strength of the glass is weak and the metal core material and metal bracket are not effectively combined, so the glass is damaged. It is a structure that cannot be strongly supported, and the solid fire extinguishing member installed in the space on one side of the frame requires maintenance and management after a certain period of time, but the entire window cannot be separated and inspected, so it cannot perform its function in the event of a fire. There was a problem that didn't exist.

The third registered patent is that the thermal expansion member in the form of a protruding plate strip is installed in a coupling groove formed on the opposing outer wall of the window frame and the window frame, and the horizontal strip is installed in a portion where the edge of the plate glass inserted into the window frame corresponds. It is designed to prevent the spread of fire and deformation of windows, but the melting point of aluminum is low and only thermal expansion members are installed on the edges of window frames and plate glass, so it is fireproof glass in accordance with the rules on building codes and standards for building evacuation and fire protection structures. There was a problem where performance related to could not be performed.

Therefore, the present invention was created for the purpose of solving the above-described conventional problems. Reinforcement material is installed inside the frame, and foam thermal expansion straps are installed between the inside of the frame and the outside of the reinforcement material to improve the frame's strength, insulation, and fire prevention functions.
