Explosion-proof windows with impact relief function

The present invention relates to explosion-proof windows and doors having an impact mitigation function, and more specifically, when the impact of wind pressure caused by earthquakes, typhoons and natural disasters and storm pressure caused by bomb explosions is transmitted to aluminum windows, / Explosion-proof windows and doors with a shock mitigation function that can flexibly absorb shock as each frame rotates up, down, left and right while absorbing shock by interposing an elastic member between the guide bar and the accommodating member to elastically support the binding part of the outer frame is about

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 windows and doors materials that increase the opening and closing methods and their efficiency by adding additional functions to these windows and maximizing wind protection, waterproofing, insulation, soundproofing and crime prevention. In reality, system windows and general windows and doors are based on the performance of windows and doors. 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.

It is installed so as to bind with the explosion and minimizes the damage of windows and doors by buffering the explosions generated by the explosion, especially strong winds.

Specifically, the accommodating member 220 is coupled to the outer frame 140, and primarily receives the external explosive pressure. Three or more of the accommodating members 220 are formed in the longitudinal direction. By accommodating the guide bar 210 of the inner frame 130 in an inserted structure, the explosion pressure transmitted from the outside is primarily accommodated. That is, the guide bar 210 moves forward and backward on the receiving hole 221 , and at this time, the elastic member 230 supports it in order to elastically relieve the impact. Here, the number of the guide bar 210 and the accommodating member 220 is provided to correspond to each other.
