Description

Dual Window Simultaneous Open and Close Device}

The present invention relates to a simultaneous opening and closing device for double-glazed windows, in particular, to automatically open a large double-walled smoke window attached to a building in case of an emergency such as a fire, and to operate it simply and conveniently manually if necessary It relates to a double-glazed simultaneous opening and closing device with improved structure.

Modern buildings have various shapes, and in particular, the floor area ratio is increased by increasing the floor height on a narrow site, and there is a tendency to enlarge the windows to secure the view. On the one hand, such a high-rise building has advantages in livability, usability, commerciality, etc., but on the other hand, there is a disadvantage that human life or property damage is increased in case of an emergency such as a fire. Considering this point, interest in fire-fighting equipment related to fire is increasing.

According to recent statistics, there were more than 40,000 fires across the country from 2009 to 2017, and in 2017 alone, 2,197 people were injured and the damage to property was over 500 billion won. More than 60% of these occurred in houses and buildings.

In recent years, when a fire occurs due to the strengthening of the fire-resistance performance of buildings and construction materials that generate a large amount of heat, gas or smoke tends to increase inside the building. According to statistics, the number one cause of death in fire is suffocation caused by smoke, and 60-70% of fire deaths are caused by suffocation or poisoning caused by poisonous smoke. Therefore, it is very important to control the smoke generated in case of a building fire so that the occupants can evacuate safely.

To this end, the Act on Building and Firefighting has regulations on smoke exhaust facilities and smoke control facilities for the rapid discharge of smoke generated in case of fire. Among them, in relation to the Building Act, Article 14 of the ‘Rules on Equipment Standards for Buildings, etc.’ specifies the contents of building smoke exhaust facilities. Exhaust facilities can be divided into natural exhaust and mechanical exhaust, and the basics of natural exhaust are smoke windows and exhaust pipes. A smoke window is a facility that detects smoke in the event of a fire and opens the window to release smoke and toxic gas, and is suitable for minimizing the casualties caused by smoke suffocation in the early stage of evacuation. On the other hand, the ‘Act on Fire Prevention, Installation, Maintenance, and Safety Management of Firefighting Facilities’ (abbreviated Firefighting Facilities Act) stipulates that firefighting equipment operated mechanically by fans and pumps is stipulated.

Smoke windows are installed in buildings so that, in the event of a building fire, they can be opened to the outside by automatically or manually controlling the smoke from the floor to be discharged immediately. The exhaust pipe, which is the outlet for discharging smoke or hot air when the smoke control facility is in operation, is connected to the smoke control windpipe and performs smoke exhaust functions in various forms depending on the smoke control method in case of a fire. A smoke window is a kind of 'natural smoke exhaust machine' that ventilates with natural power due to the density difference. In other words, when a fire occurs inside a building, the smoke window operates quickly to discharge toxic gas from the inside to the outside, thereby minimizing human casualties and making it easy to secure time for evacuation.

When installing a smoke window in a building, consider the use of the building, its size, and the scope of users, and consider the opening and closing method, the size of the window, the opening and closing angle, the installation conditions, the safety of construction, the convenience of operation and operation method, maintenance, and maintenance. Design, construction, and management should be carried out in consideration of defect management and external aesthetics of the building.

In addition, the types of smoke windows are divided into misseogi windows, pivot vertical windows, pivot horizontal windows, girder windows, middle windows, etc. (refer to Article 14 of the Rules for Building Equipment Standards, Attached Table 2). When such a smoke exhaust window is divided into an open method, it may be divided into a sliding method, a tilt method, a project method, a casement method, a pivot method, and the like.

In addition, in recent years, large windows are increasing so that the outside can be seen clearly in an interior space such as a room or office, and it is a recent trend that these windows have a double-glazed structure to more effectively respond to air conditioning or strong winds. These large, heavy-duty double-glazed windows should be opened at the same time in case of fire, especially for smoke exhaustion. In the process of simultaneously opening and closing large and high-load double-glazed windows, a structure for opening and closing double-glazed windows at the same time has been proposed as in the reference literature.

However, in these prior arts, there is a risk that the components configured in the process of repeatedly opening and closing large and high-load double-glazed windows for ventilation, etc. for a long time, and that the gap between the double-glazed windows may move slightly in the sliding process, are inappropriate in this case. There are concerns.
