BACKGROUND OF THE INVENTION

Field of the invention

The present invention relates to an elevating device installed in a building structure, and more particularly, to a normal operation for normal elevating at normal times, and switching to an emergency operation at the time of an emergency such as a fire to switch occupants. It relates to elevating devices installed in a building that has a safe place, especially an evacuation staircase that is specially installed in buildings with evacuation escape means that guides to the ground floor or outside. . Description of the prior art

Elevators and escalators, etc., for elevating and lowering are installed in ordinary buildings during normal times, and space for these elevators and other elevating means is inside the building, especially in buildings. It is concentrated near the center and is installed exclusively.

Therefore, when a fire or the like occurs, the elevating operation of these elevating means is immediately stopped, and evacuation and evacuation is impossible without using the evacuation stairs, which are specially described later. In addition, emergency elevators that can be operated even in an emergency according to the scale of the building structure can be used almost exclusively for firefighting and rescue in emergency situations, and can hardly be used for evacuation and escape. Due to the limited number of installations, many residents could not be evacuated in a short time.

Therefore, in the event of an emergency such as a fire, the majority of the residents will be required to It was necessary to use the evacuation stairs provided exclusively for evacuation.

However, it is impossible to predict when, where and how fires will occur in building structures, and under what circumstances evacuation must be performed. Therefore, this type of evacuation stairs is connected to each floor and can be evacuated from any floor, and is isolated from the room where daily use is made so that fire and smoke from fire do not enter the evacuation stairs. It is required to be a place, that is, a dedicated space.

For this reason, an evacuation staircase C for evacuation is installed in a dedicated space inside the building, which is a fire section, or along the outer wall (see Figures 23 and 24).

In an emergency, these evacuation stairs C must be evacuated by the evacuees themselves to the landing 61 from the emergency doors 60 provided on each floor and up and down the stairs 62 to escape to a safe place on their own. Did not.

The above-mentioned conventional evacuation stairs C have the following disadvantages by adopting a configuration that is permanently installed in a dedicated space inside the building and on the outer wall.

In other words, although it is a facility that is used only in an emergency and is almost never used at all, a special space is required and it cannot be used for normal residence.

In addition, the evacuees themselves must carry a long distance on these evacuation stairs on their own, and the evacuation speeds are both young and old. Evacuees temporarily and partially during evacuation without speeding It was easy to fall into a panic state, and there was even a danger of casualties resulting from unexpected accidents such as slipping.

Although the number of fires is statistically very large, it is very small in the total number of buildings, and most buildings are equipped with dedicated evacuation stairs used only in emergency situations The space became a dead space in the building and was very inefficient from the viewpoint of effective use of the building.

In addition, the evacuation stairs installed inside the building are installed with fire doors at the entrances and exits to prevent the intrusion of fire and smoke. However, depending on the actual fire situation, it may take time for the fire door to operate, or the door may not be completely closed when there is an object near the fire door. The smoke entering the evacuation stairs spreads over the evacuation stairs to the entire building in a short time as the evacuation stairs function as a chimney, causing a great deal of damage to evacuees who use the evacuation stairs. It is clear from past fire examples that it cannot be a safe evacuation site or an effective means of evacuation.

If this type of evacuation stairs is installed on the outside of the building, that is, outside, the appearance of the whole building will be significantly impaired.

Brief summary of the invention

It is an object of the present invention to provide an elevator built in a hoistway that is distributed and installed inside a building, so that occupants can use it as a general elevating means in normal times, and as an evacuation escape means in an emergency.

Another object of the present invention is to provide an elevating device installed in a building that aims to make effective use of the building in normal times by eliminating a dedicated space as an evacuation staircase that is not used at all in daily life. Is to do.

Still another object of the present invention is to enable evacuation and escape directly to the ground floor or outside by an emergency door formed in a hoistway and an escape door formed in an elevator in an emergency. An object of the present invention is to provide a lifting device installed in a building.

Still another object of the present invention is to install a hoistway and an elevator in an architectural building where transparent walls are used for elevators so that evacuees can see through the outside during evacuation in an emergency. An object of the present invention is to provide a lifting device.

Still another object of the present invention is to provide a lifting device in a building structure in which a large number of evacuees are quickly evacuated and escaped by circulating a plurality of elevators.

Still another object of the present invention is to provide an elevating device in a building that can be evacuated to another safer building by forming an elevating device between two adjacent buildings. It is in.

Detailed description of the invention

First embodiment

A first embodiment according to the present invention is shown in FIG. 1 to FIG.

The lifting device A is lifted and lowered by a lifting and lowering route 1 formed inside the building B and a driving device (not shown) built in the raising and lowering route 1. It consists of elevator 2 which is operated normally for carrying and emergency operation in case of emergency such as fire.

Carrying route 1 is used as a space for evacuation stairs. At least one side of the building B was installed near the corner facing the outer wall 11 or near the center, etc., depending on the use frequency of the elevator 2 (Fig. 2). See).

In addition, Emergency Door 3, which is opened on the ground floor corresponding to the ground floor, is controlled by the control room or operated by evacuees only in an emergency, and a fire occurs. Even so, the surrounding wall is fireproof, so that the fire does not spread from the ignition area and smoke does not enter.

In addition, the elevator hall 12 connected to the carrying road 1 on each floor has fire-resistant walls, floors, and ceilings as well as the hoistway 1, as well as the elevator 2. Each of the doors 13 that enter and exit, and the doors 14 that are formed between the elevator hall 12 and each room, use fire-resistant fire-resistant doors, and when they are closed, they are closed and smoke or fire enters. Has been prevented.

In addition, the hoistway 1 is fixedly formed by a fire-resistant structure wall, and smoke evacuation equipment 8 and ventilation holes 9 are installed as appropriate to protect evacuees from inadvertent smoke. (See Figures 3 and 4), except that the corresponding wall of the hoistway 1 is fixed and the smoke exhaust system 8 is installed, and that a part of the hoistway 1 is slid or expanded so that it can be opened and closed. In the event of an emergency operation, the window 7 formed on the external wall of the hoistway 1 was opened by remote control from the central control room to enter the subway 1 during emergency operation. Smoke can be quickly released to the outside and clean air can always be sent into the inside (see Fig. 2). Wire rope 6 formed on Therefore, it is suspended, and in normal operation during normal operation, it is driven up and down to an arbitrary floor in sequence according to the resident's use registration by a drive device (not shown).

In addition, the elevator 2 is provided with an escape door 4 directly facing the emergency door 3 formed in the carryway 1, in addition to the door 5 for use in normal operation during normal operation, In addition, various safety equipment such as smoke exhaust equipment 17, emergency lights 18 and oxygen mask 19 are installed in the interior to cope with unforeseen situations such as smoke infiltration (see Figure 4). .

Elevator A having the above configuration is installed on the roof of building B or in a special place under the control of the central control room under normal control of elevator 2 in the event of an emergency such as a fire. Switching to emergency operation by operation of the drive unit using the backup power supply by the private power generator, and using the backup control system from the control room to grasp the rated speed or operating state of elevator 2 and control and operate it Driving in response to emergencies, that is, increasing the speed of climbing or giving priority to going straight to emergency floors such as the fire floor, etc. The emergency door 3 of the hoistway 1 is opened by operation from the central control room, and when the elevator 2 descended to the ground floor faces the emergency door 3, the evacuees themselves Alternatively, the evacuation door 4 is opened by an external operation to evacuate directly to the safe outside (see Fig. 4).

In addition, after evacuating the evacuees, rush to the required floor again, board the evacuees, descend to the ground floor, and escape. Repeat to evacuate more evacuees. In addition, it can be used for firefighting activities when it rises.

In addition, when the elevator device A according to the present invention is installed inside the building B, the emergency door 3 formed at the ground floor corresponding portion of the hoistway 1 is used for normal access to the elevator 2. It is formed separately from the door 13 and an evacuation passage 10 is formed on the ground floor corresponding to the emergency door 3 above, with a fire-resistant wall around it and evacuation and escape to the outside. When emergency elevator 2 is lowered, evacuees must open escape doors 4 and emergency doors 3 and evacuate to the outside of safe building B through evacuation passage 10. (See Fig. 2 and Fig. 6).

In addition, normal operation is achieved by using the transparent wall 15 having fire resistance and heat resistance for the exterior corresponding wall of the above-mentioned road 1, and the corresponding transparent wall 16 for the elevator 2 as well. The elevator 2 in the hoistway 1 can be seen from the outside in an emergency, so that rescue operations can be carried out quickly and accurately. A sense of security can be obtained by checking the outside (see Fig. 7).

Second embodiment

9 to 11 show a second embodiment. In these embodiments, the same reference numerals as those used in FIGS. 1 to 8 denote the same components as those in the first embodiment.

The feature of this embodiment is that in the first embodiment described above, the elevator 2 built in the carriageway 1 is vertically moved up and down. Is the hoistway 1 divided into two vertical zones 21 and 21? , At least the top floor and ground Continuously communicated with the two traversing zones 22 and 22 installed on the lower floor, and a large number of elevators 2 were installed at appropriate intervals and circulated in the traversing zone 21 and the traversing zone 22. At the point where the vehicle is driven, the connecting and fixing of the vertical zone 21 and the horizontal zone 22 that form the carriageway 1 to the elevator 2 is performed by arranging guide rails 23 on the opposing side walls of the vertical zone 21. In addition, a connector 24 having rollers is provided in the elevator 2 so that the elevator 2 is firmly connected and fixed so as to be movable, and is operated by a driving device to be moved upward or downward (see FIG. 10). ).

The elevator 2 has a coupler 25 similar to the side wall on the lower surface thereof, and a guide rail 26 is provided on the bottom wall of the corresponding traversing zone 22, and the uppermost end of the vertical zone 21 is provided. Alternatively, the elevator 2 reaching the lowermost end is automatically moved to the traversing zone 22 by a switching device (not shown), and the coupler 25 on the lower surface is connected and fixed to the guide rail 26 to be fixed to the traversing zone. Move horizontally within 22 (see Fig. 9).

Reference numeral 27 denotes a chain suspended between the elevators 2 and 2 to secure the safety of the elevator 2.

In addition, the connection and movement between the vertical zone 21 and the horizontal zone 22 and the elevator 2 are performed by moving only the horizontal movement of the horizontal zone 22 by connecting and fixing the guide rail 26 and the coupler 25. It is also possible to suspend the ascent and descent in the row zone 21 by using a wire rope 28 and drive it by a driving device (see FIG. 11).

Since the elevator 2 is operated in a circulating manner on the upper and lower floors of the building B., a large number of the elevators 2 are built in the vertical zone 21 and the horizontal zone 22, but between the upper and lower elevators 2, 2. At regular intervals, like For example, if the elevator 2 is driven at a relatively low speed as an interval corresponding to the floor height of each floor and gets on and off as needed when the elevator 2 sequentially reaches each floor, it is detected as appropriate on the inner wall of the vertical zone 21 or the guide rail 23 By installing the automatic operation control device 30 in the elevator 29 and the automatic operation control device 30 in the elevator 2 respectively, and automatically adjusting the interval of the elevator 2 appropriately, the operation can be controlled by the registration of the passenger.

In an emergency, in particular, the operation control is switched to the control system of the central control room, and the elevator 2 to be carried is brought into a no-stop state, and is quickly gathered in the traversing zone 22 on the top floor. Move to the descending vertical zone 21 and rush to the fire floor or the fire spread floor where evacuees are concentrated and let the evacuees board, move down to the ground floor and use the emergency door 3 and escape door 4 Escaped quickly.

The rising elevator 2 can be loaded with fire and rescue squads to rush to the floor where digestion and rescue operations are needed.

Third embodiment

12 to 15 show a third embodiment. In these embodiments, the same reference numerals as those used in FIGS. 1 to 11 denote the same components as those in the above-described first and second embodiments.

The feature of this embodiment is that, in the second embodiment described above, the hoistway 1 composed of the vertical zone 21 and the horizontal zone 22 is formed continuously in a single building B in a circular manner. A description has been given of the case where a number of elevators 2, 2, ... are built in the hoistway 1 and circulate at any time, but the hoistway 1 is divided into two adjacent building buildings B and B. A traversing zone 31 formed independently and facing each other, and an opening 33 that connects the two adjacent building buildings B and B and can communicate with the traversing zone 31 described above. And zone 32.

The two vertical zones 31, 31 formed facing each other in the adjacent building buildings B, B have elevators 2, which are independently driven up and down in each building building B under normal conditions. The emergency operation was performed by switching the elevator 2 built in the downhill 1 of the building B where fires and other incidents occurred to emergency operation during emergency operation. Immediately rush to the floor where the traversing zone 32 is provided, and set up at the opening 33 of the traversing zone 32 facing the escape door 4 formed on the elevator 2 and the escape door 4. The emergency doors 3 are opened either manually or by another operation, and evacuees are moved from the elevator 2 to the traversing zone 32. Transfer to elevator 2 waiting on the corresponding floor in zone 31 As a result, they are evacuated to a safe place such as the ground floor immediately (see Figure 12).

The surrounding of the traversing zone 32 is a fire-resistant structure wall, and the emergency door 3 provided at the opening 33 connected to the traversing zone 31 is a fire door. It prevents the spread of fire.

In addition, the vertical zone 31 and the horizontal zone 32 that make up the hoistway 1 have smoke exhaust equipment and ventilation to eliminate smoke that has entered the hoistway 1 and to allow clean air to enter. It is desirable to install equipment separately New

In addition, the traversing zone 32 is equipped with an escalator overnight 34 that can be operated by emergency operation or other operations in addition to running on its own, and keeping the traveling speed constant, traffic congestion in one of the traversing zones 32 It also makes it easier for elderly and sick people to pass through the building and make it easier to transfer to the elevator 2 of the adjacent building B (see Fig. 14).

Further, in the above-described embodiment, the evacuee once got down on the floor where the traversing zone 32 was set up by using the elevator 2 of the building B where the fire or the like occurred, and the escape door and the emergency Opening door 3 and passing through traversing zone 32 and evacuation using elevator 2 installed in another building was explained, but traversing zone 32 was the same as vertical zone 31. The elevator 2 is built and operated so that a large number of elevators 2 can be connected between two adjacent buildings B and B in normal and emergency situations. Circulation operation is also possible (see Fig. 15).

In addition, a part of the traversing zone 32 is used as a storage place for the appropriate number of elevators 2, and in each building, the building B is operated up and down independently using the traversing zone 31 in normal times, and stored only in an emergency. By moving the reserved spare elevator 2 to the vertical zone 32 and circulating it under the control of the control room, more evacuees can be evacuated and escaped quickly.

Fourth embodiment

16 to 20 show a fourth embodiment. The same reference numerals as those used in FIGS. 1 to 15 in these embodiments. Indicates the same constituent members as those of the above-described first to third embodiments.

The feature of this embodiment is that, in the third embodiment described above, the elevator 2 having a size substantially equal to the size of the descending route 1 is built in the descending route 1 and is operated by carrying or circulating.异异 1 形成异异异异异异异异异异异异异异异异异异异异异异异异 1 1 1 异异异 1 1 1 1 异异 1 1 1 1 1 The point is that a partition wall 41 is formed, and the partition wall 41 forms an evacuation elevating zone 42 and a normal elevating zone 43.

The elevator 2 built in the above-mentioned 异 way 1 has a normal elevator 44 that is ridden in the normal carrying zone 43 during normal operation, and an elevating zone 42 that is evacuated during normal operation. It consists of an evacuation elevator 45 that is stationarily accommodated on each floor.

The above-mentioned hoistway 1 has its outer wall and side walls made of fire-resistant structural material.The partition 41, which divides the hoistway 1 into two, is divided into a normal carrying zone 43 and an evacuation carrying zone 42. A shield wall 47 is formed at the boundary of the housing to be moved toward and away from the concave groove 46. In the event of a fire, etc., the evacuation elevator 45 is evacuated from the normal lifting zone 43 to the evacuation zone. After rotating to the position 42, the shielding wall 47 is fitted into the fitting groove 46 to shield the evacuation elevating zone 42, thereby completely preventing smoke and the like from entering the fire area.

A plurality of evacuation elevators 45 descending through the evacuation elevating zone 42 are provided in the evacuation elevating zone 42 by providing a ventilation device and a smoke exhaust device so that clean air is always supplied to the inside. It is possible to ensure safety even if you wait until you reach the next ground floor.

Therefore, in this example, when a fire or the like occurs on a specific floor, the bulkhead 41 rotates 180 degrees, and the evacuation elevator 45 that is waiting to be accommodated corresponding to each floor becomes a normal elevating zone 43. The occupants of each floor are accommodated facing the elevator hall 12 on each floor. After that, after confirming that everyone was in the evacuation elevator 45, the bulkhead 41 was rotated 180 degrees again and moved to the evacuation elevating zone 42, and the shielding wall 47 attached to the bulkhead 41 Is extended and fitted in the fitting groove 46 to block the evacuation carrying zone 42.The evacuation elevator 45 is sequentially lowered and transported to the ground floor, where the emergency door 3 and the escape door 4 are used. Escaped.

The evacuation elevator 45, which descended to the ground floor and evacuated and evacuated the evacuees, moved again to the normal carrying zone 43 in the mobile area 48 on the basement floor and moved up to the floor where evacuation was required. The evacuees are sequentially carried to carry the evacuees, but these operations are operated under the control of the central control room, as in the case of the embarkation.

In addition, the evacuation elevator 45 waits in the evacuation zone 42 corresponding to each floor, and in addition to the evacuation zone 42 and the normal elevating zone 43, the evacuation elevator 45 communicates with the mobile area 48 on the basement floor side. By forming a zone 49 and accommodating a plurality of evacuation elevators 45, the evacuation elevators 45 on standby under the control of the central control room in an emergency can be used as normal elevating zones. Move to 43, rush to the emergency floor, board the evacuees one by one, move to the evacuation elevating zone 42, descend, and then move again through the moving area 48. Emergency operation to move to the normal use elevating zone 43 becomes possible (see Fig. 20).

Fifth embodiment

FIG. 21 and FIG. 22 show a fifth embodiment. In these embodiments, the same reference numerals as those used in FIGS. 1 to 20 denote the same constituent members as those in the above-described first to fourth embodiments.

The feature of this embodiment is that, in the fourth embodiment described above, the hoistway 1 is divided into a normal elevating zone 43 and an evacuation elevating zone 42 by a partition wall 41, and As described above, the evacuation elevator 45 is put in standby and the descent operation is performed for each floor in an emergency.However, in this embodiment, the hoistway 1 has the standby zone 51, the getting on / off zone 52, the ascending zone 53 and the descent zone. It consists of four zones, zone 54.A shaft 55 that rotates horizontally at 90-degree intervals in accordance with a command from the control system of the central control room is located in the center, and an elevator 2 is installed. Be worn.

The standby zone 51 formed in the hoistway 1 is capable of ascending and descending, the ascending zone 53 is driven only in the ascending direction, and the descending zone 54 is driven only in the descending direction. Also, the standby zone 51 is characterized in that a plurality of elevators 2 corresponding to each floor are accommodated in advance as much as possible. The shaft part 55 is composed of an aggregate of a plurality of nodes 56 corresponding to each floor. Each node 56 can be driven to rotate independently of the other nodes 56. Has an elevating rail portion, and after each node is moved to a predetermined position, an elevating rail is formed continuously from the upper end to the lower end of the shaft portion 55. The driving state of each elevator 2 incorporated in each of the zones 51 and 54 constituting the hoistway 1 will be described. First, in a normal state, the resident operates on one of the floors.登録 When the registration button provided in the elevator hall 12 is pressed, if the elevator 2 is waiting in the standby zone 51 corresponding to that floor, it will be rotated 180 degrees and move to the entry / exit zone 52 If the elevator 2 corresponding to that floor is not waiting, the elevator 2 waits in the standby zone 51 corresponding to the floor closest to that floor, and then moves up and down to the corresponding floor. , Turn 180 degrees and move to the entry / exit zone 52 to face elevator hall 12. If the occupant wants to go upstairs, turn 90 degrees at that position to raise Go to 53 and drive up to the desired floor, If you want to go to the lower floor, rotate to the descending zone 54 side, then descend and drive down to the desired floor.

During the congestion in the morning, most of the passengers board from the ground floor, so the elevators 2 are gathered near the ground floor using the standby zone 51, and are sequentially rotated to the getting on / off zone 52 and the ascending zone 53 to carry the elevator. The center operation is performed. In addition, in the case of daytime ascent / descent operation with a relatively small number of passengers, it is possible to use only the getting-on / off zone 52.

In the event of an emergency such as a fire, the ascending zone 53 and the getting on / off zone 52 are used exclusively for descending together with the descending zone 54 under the control of the central control room (not shown). Rotate the waiting elevators 2 to the floor where fire escape is required, such as the floor where a fire occurs, etc. Move to face the elevator hall 12 on the floor, hold the evacuees, and use only the appropriate descending zone for the carrying zone 53, the getting on / off zone 52 and the descending zone 54. , Is transported to the ground floor, and is evacuated and evacuated using the emergency door 3 and the escape door 4.
