Description

Center core of tower apartment.

The present invention relates to a central core of a tower-shaped apartment, and more particularly, to a layout structure of a central core of a tower-type apartment that is provided with a special evacuation stairs attached room which is not used in combination with a lift hole when installing the special evacuation stairs.

In the situation where it is difficult to secure an effective land due to the rise in land prices, tower-type apartments, which can be built with multiple generations on a single floor and can be constructed with high-rise and high-density construction, are gradually spreading.

The tower-shaped apartments have a small difference between short and long sides of the residential building, which is less than 1: 4, so the building occupies a small area, thus improving the efficiency of the land, and there are advantages in terms of viewing and sunshine. Also, unlike matchbox-type flatbed apartments, consumers' preferences are increasing because they can vary the appearance of buildings.

However, unlike the corridor or the staircase, there is a central corridor where the staircases and elevators are installed here (hereinafter referred to as the 'central core method'). Lighting, ventilation and ventilation problems are becoming a major drawback of tower apartments.

In addition, the focus was on supply of residential facilities, mainly flat-type apartments, and several generations of safety standard mitigation provisions that were applied to apartment houses in the past when high-rise and high-density construction were not made. In fact, they are deployed at the same time and are still applied to the present day, which is becoming a high-rise building, which is a serious risk factor for the safety of residents. The relevant architectural provisions are as follows.

First, according to Article 34 of the Enforcement Decree of the Building Act of Korea (Act on April 30, 1999) (2) No. 3, the living room used for the purpose of the officetel among apartments or business facilities is used for the purpose of the floor. If the total floor area of the floor is 300 square meters or more, two or more direct staircases are to be installed. However, this provision is specifically limited to apartments, and is limited to four households or less per floor regardless of the size of the floor area. As a result, even in the case of high-rise tower-shaped apartments, which have become the mainstream of apartments in recent years, only one direct stairway can be installed in one direction when four generations are arranged per floor. This is extremely dangerous for the safety of residents and can be improved by accessing stairs through at least two different safe spaces even if only one direct stairway is installed, as in general construction. There is a need.

Second, Article 35 of the Enforcement Decree of the Building Act of the Republic of Korea (Act Establishment of Evacuation Stairs <revised on April 30, 1999>) requires the establishment of a special evacuation staircase for a building that has more than 11 floors, or a direct access to the ground. However, in the case of multi-unit housing, the safety standards are relaxed and applied so that they can be installed as special evacuation stairs when they are over 16 stories. This is a rule considering that the evacuation ladders of fire trucks can be applied up to the 15th floor, but in reality, the first priority is to evacuate the emergency evacuation by the evacuated firefighters when it is impossible. It is not advisable to apply mitigation criteria for special evacuation stairs to

Third, according to Article 19 (Structure of Evacuation Stairs and Special Evacuation Stairs), Paragraph 2 (3) of the Rules on Evacuation and Fire Protection Structures of Buildings of Korea's Building Act, Is required to connect through balconies or through an ancillary room with an area of 1 square meter or more that can be opened outwards, or by means of an ancillary room with a flue gas installation. Is required to install emergency lifts.In accordance with Paragraph 2 of Article 15 of the Building-related Act, Building Construction Standards, etc. Although the provisions are to be made for the construction of emergency lifts, Article 10 (Structure of Platforms and Platforms for Emergency Lifts <February 9, 1999>) At No. 2, the parts except windows, entrances and other openings of platforms are to be used for other parts of the building and the floors and walls of fireproof structures. Except in the case of a multi-unit house, where the combined part of the platform and the auxiliary room of the special evacuation stairs is separated from the staircase of the special evacuation stairs, the platform can be used with the accessory room of the special evacuation system. As regulations apply, the platform of emergency lifts and the attached rooms of special evacuation stairs are in charge of the separate fire safety functions.

The reason why these mitigations are applied to multi-family housing is that the number of living rooms used for the purpose is relatively small compared to the number of people living in general buildings. It is caused by the structural problems of the existing flat-type flats composed of bays, the quantity supply policy to improve the pre-sale by reducing the common area, and social safety insensitivity.

However, recently supplied apartments are almost high-rise, and the residents are living in the daytime as well as in the night when the emergency situation is less coping, and the type of apartments are arranged in the form of multiple generations on one floor. As the tower type is becoming mainstream, the public area is getting bigger than the flat type apartments, and it is a serious problem for the safety of residents in the situation that the awareness of improvement of the living environment and the safety is being raised from the past supply policy. A safer public space is needed, while improving the risky areas, reflecting the realities of the apartment, such as consideration of economics and predominance and the proportion of the public area compared to the private area.

On the other hand, in the spread of the fire, a corridor, a staircase, or a facility passage mainly serves as a passage for spreading, and an upward airflow occurs through a staircase, an elevator shaft, a pipe shaft, and the like vertically. This vertical spread also causes significant disruption to residents' evacuation and fire brigade activities. In particular, apartments share stairs or corridors, so if households are polluted by smoke, each household may have difficulty evacuating through the stairs. Therefore, measures to reduce the possibility of contamination of stairs are needed. Additional evacuation arrangements should be in place to deal with the presence of an emergency.

More specifically, when the staircase, which is the main evacuation means, is exposed to the smoke caused by the fire, the moving smoke is from the first floor to the 12th floor when the horizontal speed of the smoke is 0.3-1 m per second and the vertical speed is 2-3 m per second. Since it takes less than a minute to reach, evacuation through the stairs is not practical in this case, so there is a need to live and wait safely on the floor after the smoke has spread.

On the other hand, the stairs and elevators, which are in charge of vertical movement of high-rise and high-rise apartments, have different roles. In the case of staircases, they are used as the most important vertical movement in case of emergency such as fire. On the other hand, elevators are limited in use in emergency situations such as staircases, but in general, almost all generations use them as the main vertical means of transportation, and this phenomenon becomes more prominent as they rise higher and higher. In addition, the separation of elevators from the staircase, which can be used for evacuation, even though there is a possibility of vertical spread of the fire in the event of a fire, can reduce the possibility of fire contamination of the staircase, thus ensuring a safer evacuation passage. Necessity is emerging.

1 and 2 are examples of main tower-shaped apartments. 1 shows a common corridor of the central core in a vertical direction, with the second entrance having a front entrance at the back and the second entrance having a front entrance at the front. At this time, the public spaces in front of the second generation at the rear are adjacent to the external space, but the public spaces at the front of the second generation at the front are not only enclosed without being connected to the external space, but also mixed with the common space of the central core without arson compartment. When exposed to the danger of fire in the household location, there is no other method than evacuation using the staircase of the central core. At this time, if there is a problem in the evacuation method through the staircase room, no separate evacuation method can be found. In addition, if the second generation is exposed to the risk of fire, the evacuator may be able to evacuate horizontally in addition to the vertical passage using the stairway. It could also spread to this central core, which could eventually cause danger to the entire building through a vertical rise in fire risk. As a result, generations placed in front of and behind the central core may face difficulties in safe evacuation in the event of a fire. In addition, since the common space of the central core has a dead-end corridor, it causes many problems in ventilation. On the other hand, Figure 2 is a way to arrange the common corridor of the central core in the horizontal direction, 2 generations on the left side and 2 generations on the right side around the center core, a part of the left and right common space is connected to the external space, respectively have. Thus, unlike this method, there is no dead-end corridor type, which is more advantageous in the ventilation problem. However, in FIG. 2, the common spaces of the left and right generations and the common core are mixed so that the risk of fire can be spread to the central core, which can cause danger to the entire building through the vertical rise of the fire risk. This is a problem.

On the other hand, evacuation at higher floors is more difficult to reach the entrance to the ground than at lower floors, and it may be difficult to evacuate itself if a fire occurs at the evacuation floor. In particular, in the case of a tower-type apartment in the form of a multi-composite type, the mall is installed on the lower floor, so even if you escape to the evacuation floor through the vertical evacuation passage, you must pass through the mall to the external space, which is a complete evacuation space. There is more difficulty. Therefore, evacuate to the evacuation floor safely, but when the situation is not easy, it should be possible to secure safety simply by horizontal evacuation.

In order to cope with these dangerous situations, additional evacuation other than vertical evacuation, which is the only evacuation method, is made, along with safer measures to meet the changes in the building's era by improving the safety standard mitigation measures that have been unreasonably applied. I need a way.

The present invention has been made to solve the problems of the prior art, the object of the present invention is to install a special evacuation staircase in the tower-shaped apartment, so that the daylighting and ventilation of the common space is smoothly made so that the living environment is made hygienic The construction of elevator halls that do not combine with other spaces ensures safety and raises the level of living environment, and separate stairwells that do not share with elevator halls are the main means of evacuation to emergency floors in case of emergency. The staircases are to be safely protected, and more than two different fire zones can be connected to the staircase through the stairwells of the stairwells to ensure safer evacuation. To provide the central core of the tower-shaped apartment The.

In order to achieve the above object, the central core of the tower-shaped apartment according to the present invention aggregates four generations on one floor, and in the central core of the tower-shaped apartment when installing special evacuation stairs, the central core is It includes two common rooms having a space in front of the entrance of the household commonly used by the second generation as an interior space, a lift hall directly connected to the elevator, and a staircase directly connected to the stairs attachment room. The common room is located next to each other, and the elevator hall and the common room are each divided by fire doors. The staircase and the common room are connected through separate stairwells that are not used together with the elevator hall. In addition, some surfaces of the two common rooms are provided with opening and closing windows in contact with the outside air, and configured to allow external ventilation.

In addition, the central core of the tower-shaped apartment according to the present invention for achieving the above object is arranged by concentrating four generations on one floor, the central core of the tower-shaped apartment in the case of installing a special evacuation stairs, the central core is It includes two common rooms having a space in front of the entrance of the household commonly used by the second generation as an interior space, a lift hall directly connected to the elevator, and a staircase directly connected to the stairs attachment room. The common room is located next to each other, and the elevator hall and the common room are each divided by fire doors. The staircase and the common room are connected through separate stairwells that are not used together with the elevator hall. In addition, in the two common rooms, a flue gas facility is provided in the inner space when the outside air cannot be contacted and is configured to discharge smoke.

In addition, the fire door between the elevator hall and the common front room is preferably configured to close automatically when the fire detector detects a fire.

In addition, the staircase attachment chamber is preferably configured to install a window that can be connected to the outside air or is equipped with a flue gas facility to discharge the smoke.

In addition, the staircase attached compartment is partitioned into the common room and the fire door, it is preferable that the staircase attached compartment and the staircase also divided into a fire door.

In addition, in the case where only one staircase chamber is provided, it is preferable that two staircase attachment chambers are positioned and connected to both sides of the staircase chamber, respectively.

As described above, the central core of the tower-shaped apartment according to the present invention has the following advantages.

First, separate elevators from the staircase, which is the main vertical evacuation corridor, with the possibility of vertical spread of fire but not for evacuation, and construct separate stairwells that do not serve as elevator halls. The staircase, the main means of evacuation, can be safely protected.

Second, in two or more different fire zones, two-way evacuation is possible by connecting to the staircase through the stairwell.

Third, it is possible to increase the level of residential environment in the central core common space by constructing a dedicated hall of a high frequency elevator.

Fourth, as the apartment becomes high or ultra high rise where a fire ladder cannot be used, it is possible to prevent fatal casualties that may occur when the evacuation stairs, which are the only means of evacuation, are contaminated with fire. In other words, by dividing the common space of the central core into fire doors to create a fire zone of a different nature, it is possible to drastically reduce the possibility of pollution caused by the fire in the public space, and to ensure safety by vertical evacuation and horizontal evacuation.

Fifth, it is possible to solve the problem of mining and ventilation for the common space of the central core, which is indicated as a fatal disadvantage as the tower-shaped apartments become the mainstream of the apartment living culture.

Sixth, in case of high-rise apartments, it is necessary to make evacuation floors rather than residential spaces at certain intervals for safety. However, according to the present invention, since there is no need to install a separate evacuation layer, a lot of economic effects can be obtained.

Seventh, by providing uncontaminated public space, sufficient firefighting time can be secured to ensure the safety of firefighters.

Hereinafter, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings. 3 and 3-1 are schematic diagrams illustrating an indoor plan of a tower-shaped apartment according to an embodiment of the present invention, and FIGS. 5 and 5-1 and 6 and 6-1 are various embodiments of the present invention. A real interior floor plan of a pagoda apartment according to.

One end of the central corridor, which is a component of the central core, is configured to contact the outer space. In addition, the central core is the elevator corridor 600 and 2 directly connected to the public corridor in front of the generation entrance shared by the second generation and the public corridor in front of the household inlet shared by the second generation. It is divided into four zones by using the stairs 700 which are directly connected to the two accessory chambers 900 and 910. The elevator hall 600 is divided into a common corridor using the first fire door 100 and the second fire door 110, and the staircase 700 is shared using the first accessory room 900 and the second accessory room 910. It is separated from the hallway. In addition, the first accessory chamber 900 is distinguished from the staircase 700 and the common corridor by using the first stair fire door 210 and the first accessory fire door 200, and the second accessory room 910 is the second stair fire door 230 ) And the second accessory room fire door 220 to distinguish the staircase room 700 and the other common corridor.

As a result, the first common room 500 adjacent to the exterior space is formed in front of the entrance entrances of generations 1a 400 and 1b 410, and in front of the entrance entrance of generations 2a 420 and 2b 430. An adjacent second common chamber 510 is formed, and an elevator hole 600 is formed in front of the elevator 800, and first and second auxiliary chambers 900 and 910 are formed at both sides of the stair chamber 700. Opening and closing windows are provided on a surface of the first shared room 500 and the second shared room 510 that contact the external space. In addition, depending on the conditions of the building, the number of staircases can be installed in only one case and in two or more cases.In case of installing only one staircase, ancillary rooms 900 and 910 are installed on both sides of the staircase 700. In the case where two staircase rooms are installed, a first accessory chamber 900 is installed in the first staircase chamber 710 and a second accessory chamber 910 is installed in the second staircase chamber 720. If only one staircase is installed, one staircase can also be installed and connected to two shared rooms, and the number of staircases can be determined according to the arrangement and installation conditions of the central core. It is desirable that the staircase and the exterior space be adjacent but are not essential.

The first fire door 100 and the second fire door 110 have a structure that automatically closes in the event of a fire through a fire detector that can detect heat, smoke, etc., even if the door is always closed or open. Regarding the structure of fire door closing automatically according to the signal of fire detector, Japanese Unexamined Utility Model Publication No. 49-106136 (fire door stop device using electromagnet), Korea Utility Model Registration Application No. 1982-9100 (Magnetic Automatic Closing Device) , Korean Patent Application No. 10-1996-51785 (Automatic Stopper Device and Fire Door Closer), Korean Utility Model Registration Application No. 20-0431191 (Automatic Closure Device of Door) , The detailed description is omitted here.

The installation position of the fire detector is selected and installed among the common rooms 500 and 510 and the elevator hall 600, and the final installation position may be determined by the user. When installed only in the common room (500, 510) fire detection occurs in each generation is fast, but when installed in the elevator hall 600, the detection of fire that can rise vertically through the elevator passage is fast.

In addition, the first accessory chamber 900 and the second accessory chamber 910 are provided with a window that can be connected to the outside air, or equipped with a flue gas facility.

In the elevator hall 600, the first fire door 100 and the second fire door 110 are often left open, so that light and ventilation will be smoothly performed, and the stairwell 700 in the common rooms 500 and 510. The first accessory chamber 900 and the second accessory chamber 910 which are connected to each other have a low frequency of normal use except in emergency evacuation, so that the first accessory fire door 200, the first stair fire door 210, and the second It is not necessary to open the attached room fire door 220 and the second stair fire door 230, the fire compartment of the staircase room can be maintained completely the initial installation purpose.

The first common room 500 and the second common room 510 may serve as an evacuation space that may prevent asphyxiation due to smoke introduced in a fire adjacent to external air. However, as shown in FIGS. 4 and 4-1, if the first common room 500 or the second shared room 510 cannot be adjacent to the outside air, the flue gas installation 1000 is introduced therein. Allow smoke to escape.

In addition, the first common room 500 and the second common room 510, which are evacuation spaces, are all rooms shared by two or more generations, and there is no difficulty in using space, such as installation of a locking device according to the first generation of emulsification. In other words, the purpose of the initial intended space can be maintained.

Referring to the operation of the central core of the tower-shaped apartment configured as described above are as follows.

The central corridor, which consists of the elevator hall 600, which is usually used for vertical movement, and the first common room 500 and the second common room 510, which are evacuation spaces, usually suffers from indoor lighting problems through light from the outside space. In addition, the ventilation problem may also be solved because the outside air may be introduced into the center corridor.

If only one staircase is installed, if a fire occurs in generation 1a (400) or a fire occurs in a generation below, the household entrance fire door (300) is opened and the first common room ( Evacuate to 500) and close the next door entrance fire door (300). If you continue to evacuate to the evacuation floor to ensure safety completely, open the first attached room fire door (200) from the first common war room 500 to the staircase 700, evacuate to the first accessory room 900, and then the first Close the attached fire door. Then open the first staircase fire door 210, evacuate to the staircase 700, and closes the first stairwell door. Then, evacuate to the evacuation floor through the staircase 700 to complete the vertical evacuation. In this case, since the staircase chamber 700 is connected to the first common war room 500 through the first accessory chamber 900, there is little possibility that the staircase chamber 700 is contaminated by fire. However, if the staircase 700 is contaminated with fire and it is impossible to vertically escape through the staircase 700, the first fire door 100 which is always closed or automatically closed through the fire detector is opened and the elevator hole 600 is opened. After evacuation, the first fire door 100 is closed. Thereafter, the second fire door 110 is opened, the second fire door 510 is evacuated, and the second fire door 110 is closed to complete the first horizontal evacuation.

After completing the first horizontal evacuation, wait for external assistance in the second common room 510 or form a fire compartment with the help of Generation 2a 420 or Generation 2430. Evacuation to generation 420 or generation 2b 430 completes the horizontal evacuation.

On the other hand, when two staircases are installed, if a fire occurs in generation 1a (400) or a fire occurs in a generation below, the household entrance fire door (300) is opened and the first common room is opened. Evacuate to 500 and close the next generation front door fire door (300). If you continue to evacuate to the evacuation floor to ensure complete safety, open the first sub-chamber fire door 200 leading from the first common war room 500 to the first stair room 710 and evacuate to the first sub-room 900 Close the first attached fire door. Then, the first staircase fire door 210 is opened and evacuated to the first staircase room 710 and the first stairwell door is closed. Then, evacuate to the evacuation floor through the first staircase 710 to complete the vertical evacuation. In this case, since the first staircase chamber 710 is connected to the first common room 500 through the first accessory chamber 900, there is little possibility that the first staircase chamber 710 is contaminated by fire. However, if the first staircase 710 is contaminated with a fire and vertical escape through the first staircase 710 is impossible, the first fire door 100 which is always closed or automatically closed by the fire detector is opened and the elevator hall is opened. Evacuate to 600 and close first fire door 100. Thereafter, the second fire door 110 is opened, the second fire door 510 is evacuated, and the second fire door 110 is closed to complete the first horizontal evacuation.

If you continue to evacuate to the evacuation floor to ensure complete safety even after completing the first horizontal evacuation, open the second accessory room fire door 220 leading from the second common room 510 to the second staircase 720. 2 Evacuate to the attached room 910 and close the second attached fire door. Then, the second staircase fire door 230 is opened and evacuated to the second staircase room 720 and the second stairwell door is closed. Then, evacuate to the evacuation floor through the second staircase 720 to complete the vertical evacuation. In this case, the fire occurred on the generation 1a 400 side, and the second staircase 720 is also connected to the second common room 510 through the second accessory room 910, so that the second staircase 720 is contaminated with the fire. It is unlikely to be. However, if the second staircase 720 is also contaminated with fire and it is impossible to vertically escape through the second staircase 720, wait until there is external support in the second common room 510, or With the help of 420 or 2b generation 430, the evacuation to generation 2a 420 or generation 2b 430 forming a fire compartment is completed.

This evacuation method is equally applicable to the remaining generations, namely generation 1b 410, generation 2a 420, generation 2b 430, and the like.

On the other hand, the firefighter can deploy the firefighting activity through the elevator 800, and at this time, since the elevator hall 600 is safely protected from fire, it can greatly help in developing the firefighting activity.

As described above, the present invention has been described only with respect to specific examples, but it is apparent to those skilled in the art that various changes and modifications can be made within the technical spirit of the present invention based on the above specific examples. Naturally, the modifications belong to the appended claims.
