Explosion-proof window with easy shock absorption

The present invention relates to an explosion-proof window that can easily absorb shock, and specifically, when the impact of wind pressure caused by an earthquake, typhoon and natural disaster and storm pressure caused by a bomb explosion is transmitted to the explosion-proof glass, it is pushed backward by the explosion pressure. It relates to an explosion-proof window with easy shock absorption that protects human life and promotes safety by the impact transmitted to the explosion-proof window by bonding to the chassis so that the explosion-proof glass is not damaged.

In general, fittings are a type of movable work piece, such as a window or a door, which is installed in an opening to block the inside of a building from the outside or to separate the interior space itself from each other, so that opening and closing and detachment are free. Similar to the exterior wall, the window function in the opening provided on the exterior wall of the building protects the interior from external weather changes or intruders, blocks external noise and internal light or sound, and prevents ventilation, ventilation, or sunlight. It has the function of blocking the outside and the inside by opening and closing the windows.

System windows and doors refer to window materials that increase the opening and closing method and efficiency by adding additional functions to these windows and maximize wind protection, waterproofing, insulation, soundproofing and crime prevention. is divided into

On the other hand, explosion-proof (Blast Resistant) refers to an explosion-proof technology that absorbs impact and explosive energy during an external explosion to reduce the load on surrounding structures, and the windows to which such explosion-proof are applied are explosion-proof fittings. Explosion-proof windows with shock absorption systems can prevent local destruction and chain collapse of buildings, and block explosion damage to the exterior walls of buildings to prevent casualties and property loss.

Up to now, all facilities have installed windows for outside and ventilation and doors for entry and exit on the roof to block rain or snow and the wall to block exposure to the outside. It was insufficient to prevent damage to life and property from special wind pressure or storm pressure. In particular, after the terrorist incident in the United States on September 11, 2001, in the United States, all major commercial, government and military facilities have been replaced with explosion-proof windows with explosion-proof functions, and new facilities are required to apply explosion-proof windows as a rule.

Therefore, the same regulations are applied to developed countries in other countries, and explosion-proof windows are applied and installed to prevent damage to human life and property, especially in airports and commercial facilities with a lot of people coming in and out.

Hereinafter, we will take a look at the description of the existing explosion-proof windows and their problems with some examples.

When an external explosion pressure is generated, the explosion pressure shock is relieved by the shock absorbing rod accommodating part 210 and the shock absorption rod 220, that is, an explosion-proof pressure corresponding to the external explosion pressure is formed to elastically absorb the impact energy. By absorbing it, it is possible to prevent the destruction and detachment of the inner/outer frames 130 and 140 and the building frame wall 300 . At the same time, it will serve to absorb and buffer the explosion pressure double by the buffer part 111 of the explosion-proof glass 110 at the same time.
