Description

Explosion-proof window {Blast resistance window system}

The present invention relates to an explosion-proof window, and more particularly, to an explosion-proof window in which the damper is integrally molded inside the window frame.

A window is a general term for windows and window frames installed on a wall of a building. The windows play a role of introducing external light into the room and adequately ventilating the indoor air. In the closed state, the windows block the heat flow of the indoor and outdoor to maintain the indoor cooling and heating effect. The window frame is a frame fixed to the wall means that the window is provided with a glass window is inserted. The window frame is generally used after extrusion molding a synthetic resin material, cut to match the length of the window frame to be constructed. Walls of various buildings such as apartments or buildings are usually provided with a window frame having a rectangular frame shape, and then a pair of windows are provided inside the window frame, and the window has a rectangular frame shape corresponding to the size of the window frame. The center portion of the window is provided with a glass is configured to have a structure that can be opened and closed while moving left, right or up, down in the inner side of the window frame. On the other hand, windows and doors are physically destroyed by wind pressure or explosives generated from explosives when a natural disaster such as a typhoon occurs. There is a risk of injury and loss of property in that it can be broken and scattered and the window frame is locally destroyed, which can lead to the collapse of the structure. Therefore, in order to prevent this, explosion-proof windows to which explosion protection technology is applied to absorb external impact and explosion energy to reduce the load on the surrounding structure have been applied. Recently, by installing a shock absorbing bracket between a frame wall and a window frame of a building, or between an inner frame and an outer frame of a window, when a large pressure is generated from the outside, the shock caused by the explosion pressure is alleviated by the bracket. Explosion-proof windows and doors are being developed to prevent the destruction and detachment of frame walls. US Patent No. 06764729 is provided with a second explosion-proof bracket installed in contact with the frame wall of the building and a first explosion-proof bracket seated on the second explosion-proof bracket, the first explosion-proof bracket in contact with the inner frame leg of the window and bolt An explosion-proof window having a structure combined with is disclosed. In addition, Korean Patent Laid-Open Publication No. 2009-0124580 discloses a first shock absorbing bracket having a second shock absorbing bracket coupled to an outer frame of a window and the first shock absorbing bracket coupled to an inner frame of a window. Discloses an explosion-proof door having a structure fixed to a second shock absorbing bracket for receiving external pressure in a third interval with a shock absorbent for receiving external pressure in between. However, in the case of the explosion-proof doors, a large number of brackets having a damper function to reduce external pressure, a member such as a bolt, a shock absorber provided with a material such as polyamide for the connection is required Not only will the production cost increase, but the weight of the product increases, which is inefficient, and the labor for assembly increases, which is disadvantageous in construction.

The present invention is to solve the problems described above, and an object of the present invention is to provide an explosion-proof door having a damper formed integrally with the window frame.

In order to achieve the object described above, the present invention is an explosion-proof window provided with a fixed frame fixed to the wall of the building and a window frame installed on the inside of the fixed frame, the inside of the window frame integrally with the window frame A molded damper is provided, wherein the damper is connected between the first inner window frame located on the side where the glass is inserted and the second inner window frame located on the corner bracket insertion hole, and the shape of the damper is shaped like a pleated accordion. It provides an explosion-proof window characterized in that.

Here, the damper is preferably formed continuously along the inner circumference of the window frame.

Here, the damper is preferably made of aluminum.

Here, the damper is preferably applied to the window of the tilt-turn (Tilt-Turn) method.

According to the present invention, by reducing the external explosion pressure to reduce the transition of the explosion energy delivered to the building it is possible to implement an explosion-proof window that can reduce the human and property damage caused by physical destruction, in particular light weight, Explosion-proof windows can be implemented to drastically reduce production costs, labor and construction time.

FIG. 2 is a cross-sectional view illustrating the damper of FIG. 1.

Hereinafter, preferred embodiments of the explosion-proof window according to the present invention will be described in detail with reference to the drawings. The terms or words used below should not be construed as being limited to ordinary or dictionary meanings, and the inventors can properly define the concept of terms in order to explain their invention in the best way. It should be interpreted as meanings and concepts corresponding to the technical spirit of the present invention.

Explosion-proof windows according to the present invention includes a window frame 100, a fixed frame 200 and a damper 400.

Explosion proof windows are equipped with dampers that can absorb and exhaust energy due to large pressures caused by external explosions inside the windows and reduce energy transfer to buildings by attenuating energy caused by large external pressures. To prevent property loss. The damper 400 is integrally provided inside the window frame 100. The damper 400 is disposed between the first inner window frame 102 positioned at the side where the glass 300 is inserted inside the window frame 100 and the second inner window frame 104 positioned at the corner bracket insertion hole 120. It is molded integrally with the window frame 100 in the form of connecting the. In this case, the damper 400 may be made of the same material or different materials as the window frame 100. In addition, the damper 400, as shown in Figure 2, may be provided in the form of a pleated accordion. When the damper 400 is formed as described above, the damper 400 absorbs the external pressure energy by itself as the spring absorbs the external pressure and exhausts the external pressure even though the damper 400 receives the large pressure from the outside. It is possible to reduce the transfer of the bursting energy to the component or building. The damper 400 is designed so that the stress due to the explosion pressure reaches the plastic region in the elastic region beyond the tensile strength of the material before the other components of the explosion-proof window, but does not exceed the ultimate strength of the material. For the design, the optimization techniques of "Strain Energy Density Optimization" and "Internal Energy Density Optimization" are applied. By the optimization technique, the damper 400 is designed to cause local axial deformation, not overall bending deformation, due to large external pressure. This can protect the components of the windows from the external pressure while minimizing the weight, it is possible to implement the explosion-proof windows that can reduce the cost. The contents of the explosion-proof windows provided with the damper 400 as described above may be applied to all kinds of windows.

The damper 400 may be continuously formed along the inner circumference of the window frame 100. In the case of a window frame having a rectangular shape, the window frame is continuously formed along the circumference of the rectangular shape to surround the window frame 100. The cross section as shown in FIG. 1 is formed by cutting any of four corners of the U.S. explosion-proof window, and the damper 400 as shown in FIG. 1 is continuously formed along the edge of the explosion-proof window.

In addition, the damper 400 may be made of aluminum. The window frame 100 may also be made of aluminum, in which case it is easy to integrally mold the damper 400 and the window frame 100 in a mold. When the window frame 100 is made of different materials and the damper 400 is made of aluminum, the damper 400 is manufactured separately to form the damper 400 in a mold for forming the window frame 100. After positioning first, the window frame 100 is molded by injecting the material to be manufactured.

The damper 400 may be applied to the explosion-proof window of the tilt-turn (Tint-Turn) method. The tilt-turn method is a kind of opening and closing method, and a fixed frame 200 is fixedly installed on a wall of a building, and a window frame 100 is installed inside the fixed frame 200. It rotates about an axis and opens and closes left and right or up and down. 1 is an explosion-proof window according to the present invention, in particular, one end surface of the explosion-proof window of the tilt-turn (Tint-Turn) type, which is a kind of casement window in which the glass 300 is fitted to the window frame 100.
