Description

An earthquake-proof safety door structure that can respond to earthquake disasters

The present invention relates to a safety door device that can respond to earthquake disasters, and more specifically, because it has a simple but efficient structure compared to the prior art, even if the door frame is deformed due to an earthquake, etc., there is no difficulty in opening the door safely It relates to a safety door device that can be used and can respond to earthquake disasters.

Recently, due to a series of large earthquakes occurring both at home and abroad, awareness of the damage caused by earthquakes and the need for earthquake-resistant design are spreading, and interest in methods of earthquake-resistant reinforcement of buildings is gradually increasing.

If designing a building strong enough to resist seismic force is a general seismic design, vibration control is a method of minimizing damage to a building by using various devices for input energy caused by an earthquake.

Even for buildings designed according to earthquake-resistant design standards, structural damage caused by earthquakes cannot be avoided, and the safety of human life may be threatened. Interest in vibration suppression technology that can be safely preserved is growing.

Most of the high-rise buildings currently being constructed are designed according to the seismic design standards, and a representative vibration damping device applied to a building is a damper.

As such dampers, steel dampers, friction dampers, oil dampers, viscoelastic dampers, and the like are used.

As an example of the vibration damping device as described above, domestic registered patent No. 10-1026106 discloses a joint structure of a vibration damper installation frame, and domestic registered patent No. 10-1114908 discloses a building earthquake-resistant reinforcement method using a smart frame. there is.

And, domestic registration patent No. 10-1000206 discloses a window system with seismic performance. The disclosed window system has a configuration in which a damper made of a plate-like member having a predetermined thickness and width in which a slit-shaped hole is formed between an external frame and a support beam is installed. However, the window system has a limit in preventing deformation of the pillar member and the support beam installed inside the outer frame.

On the other hand, the biggest problems when an earthquake occurs are as follows. That is, when an external force acts on a building structure due to an earthquake or the like, the external force may be transmitted through the building structure.

In this case, when a door for evacuation of a door is installed in the building structure, the load due to the external force is transmitted to the door frame of the door, and deformation of the door frame may occur.

As such, when the door frame is deformed, the door connected to the door frame may not be opened. This may endanger people's safety by closing the evacuation route where people can evacuate in situations such as earthquakes.

Accordingly, although a safety door having a structure as shown in FIG. 1 has been proposed, in the case of the technology shown in FIG. 1, the structure is too complicated, which causes an increase in cost, and also has great difficulty in practical application. Considering this, the need for a safety door device that can respond to earthquake disasters arises.
