Description

Technical Field

[0001] This invention relates to an evacuation passage, and more specifically to a fire evacuation passage in a standard floor of a super high-rise building and its design method. Background Technology

[0002] In recent years, to address numerous issues such as land scarcity, the number of super high-rise buildings has been increasing. However, their fire safety problems have become increasingly prominent, including high population density, difficult evacuation, and challenging firefighting. In office buildings, to improve work efficiency, office space further encroaches on circulation space, resulting in limited evacuation corridor widths, while the number of people using the space often exceeds the estimated number. These evacuation corridors are a crucial link in the evacuation system of super high-rise buildings. In the event of a disaster, evacuees enter evacuation staircases from these corridors. Due to the excessive concentration of people, congestion occurs in the evacuation corridors, significantly reducing evacuation efficiency and further highlighting fire evacuation problems. Current regulations only stipulate a minimum width for evacuation corridors, and existing practices only meet this minimum width without exploring the impact of the upper limit on evacuation efficiency. Furthermore, current regulations only specify a single value for the width of evacuation corridors, which is often fixed and does not adjust according to the distribution of evacuation density, making it difficult to adapt to changes in evacuation and escape behaviors on standard floors. Therefore, it is necessary to optimize the design of evacuation corridors in the standard floors of super high-rise buildings to improve evacuation efficiency in the event of a disaster. Summary of the Invention

[0003] The main technical problem solved by this invention is to provide a fire evacuation corridor and its design method for a standard floor of a super high-rise building. This method can solve the congestion in the evacuation corridor when a disaster occurs. People can also choose to wait for rescue or make a rapid descent to deal with emergencies, thereby maximizing safety performance.

[0004] To solve the above-mentioned technical problems, according to one aspect of the present invention, more specifically, a fire evacuation corridor for a standard floor of a super high-rise building, comprising a standard floor, the standard floor including office cubicles, an open office area, an evacuation corridor, a vestibule, an evacuation stairwell, and a descent room, the open office area having a first escape exit, the evacuation corridor having a first fire door, the vestibule having a second fire door, the open office area being connected to the evacuation corridor through the first escape exit, the evacuation corridor being connected to the vestibule through the first fire door, the vestibule being connected to the evacuation stairwell through the second fire door, and the descent room being connected to the vestibule.

[0005] Furthermore, the floor of the descent chamber is embedded with a base plate, the upper surface of which has a through-type second escape opening. Two sets of fixing plates are embedded inside the base plate. A first linkage groove is formed on the opposite side of each fixing plate. A load-bearing plate is slidably connected inside the first linkage groove. A limit plate is fixedly connected inside the first linkage groove. A turbine cylinder is rotatably connected through the left side of the limit plate. A screw is threaded inside the turbine cylinder. The end of the screw away from the turbine cylinder is fixedly connected to the limit plate. Two sets of gear discs are rotatably connected inside the first linkage groove. The gear discs mesh with the turbine cylinder. A first bevel gear is integrally formed on the upper surface of each gear disc. The fixing plate... A second linkage groove is symmetrically provided on opposite sides. A first straight rod is rotatably connected inside the second linkage groove. A second bevel gear is fixedly connected to the outer wall of the first straight rod. A connecting rod is provided inside the first linkage groove. A third bevel gear and a fourth bevel gear are fixedly connected to the two ends of the connecting rod, respectively. The third bevel gear meshes with the first bevel gear, and the fourth bevel gear meshes with the second bevel gear. A screw block is threaded to the outer wall of the first straight rod. A U-shaped piece is fixedly connected to the upper surface of the screw block. A shaft is rotatably connected inside the U-shaped piece. A support rod is rotatably connected to the outer wall of the shaft. A hinge is rotatably connected to the opposite ends of the two support rods. A lever is fixedly connected between the hinges.

[0006] Furthermore, a working groove is formed on the upper surface of the fixing plate. A driving gear is rotatably connected inside the working groove. A driven gear is meshed with the outer wall of the driving gear. A working rod is fixedly connected inside the driven gear. A fifth bevel gear is fixedly connected to the outer wall of the working rod. The fifth bevel gear meshes with the first bevel gear. A safety block is fixedly connected inside the working groove. A crossbar is fixedly connected to the left end of the safety block. A safety component is slidably connected to the outer wall of the crossbar. The safety component is adapted to the driving gear. A first workpiece is fixedly connected to both ends of the right side of the safety component. Safety buckles are slidably connected to the front and rear ends of the safety block. A second workpiece is fixedly connected to the left end of the safety buckle. A safety rod is rotatably connected between the first workpiece and the second workpiece.

[0007] Furthermore, the rappelling chamber is equipped with rappelling rescue equipment, which is compatible with the lever.

[0008] Furthermore, the safety buckle is made of magnetic material, and a magnetic component is fixedly connected inside the working groove, so that the safety buckle and the magnetic component are attracted to each other.

[0009] Furthermore, the cross-sectional width of the evacuation corridor varies, being narrower near the escape exit and wider near the first fire door.

[0010] According to another aspect of the present invention, a design method for rapid fire evacuation routes in standard floors of super high-rise buildings is provided, comprising the following steps:

[0011] S1. Establish an evacuation corridor that is partially widened near the first fire door. The widening of the evacuation corridor near the first fire door provides a buffer space for personnel to escape.

[0012] S2. The personnel escape behavior is set as follows: enter the open office area from the office cubicle, enter the evacuation corridor through the first escape exit, enter the anteroom through the first fire door, and then enter the evacuation stairwell through the second fire door.

[0013] S3. When personnel are physically exhausted or need rescue, they should stand in the rappelling chamber and wait for rescue.

[0014] S4. Personnel can install the rappelling rescue equipment with the lever, and then other personnel can push the safety buckle to both sides to attract the magnet, and at the same time drive the safety bar to move, causing the safety component to separate from the drive gear, and then the user can rotate the drive gear;

[0015] S5. The driving gear drives the driven gear to mesh and rotate, thereby causing the gear disk to rotate, moving the load-bearing plate, thus exposing the second escape opening, and causing the support rod to be raised, allowing personnel to quickly descend and escape through the descent rescue equipment.

[0016] The beneficial effects of the fire evacuation corridor and its design method for a standard floor of a super high-rise building according to the present invention are as follows:

[0017] By setting up locally widened evacuation corridors, the front space of the floor's safety exits was expanded, effectively increasing the space's capacity to accommodate people, solving the problem of crowding near the first fire door during escape, and improving the efficiency of personnel evacuation in the event of a disaster.

[0018] The gear disk drives the turbine cylinder to rotate, which in turn causes the screw to rotate and move the load-bearing plate, thus opening the escape hatch. At the same time, the turbine cylinder drives the second bevel gear to rotate, which in turn causes the screw block to rotate further to the opposite side, further lifting the support rod upward, and thus raising the hinge and lever to facilitate the subsequent escape of personnel.

[0019] The safety buckle moves to both sides, causing the safety bar to move, which in turn separates the safety component from the drive gear, allowing the drive gear to rotate. Normally, the safety buckle is closed to prevent accidental contact by outsiders from exposing the escape hatch and causing an accident.

[0020] The active gear drives the driven gear to rotate, thereby rotating the two turbine cylinders. Two sets of these gears are set to increase safety performance. Attached Figure Description

[0026] The present invention will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in the present application can be combined with each other.

[0027] According to one aspect of the present invention, a fire evacuation corridor for a standard floor of a super high-rise building is provided, comprising a standard floor 1, which includes office cubicles 40, an open office area 41, an evacuation corridor 2, an anteroom 3, an evacuation stairwell 4, and a descent room 5. The open office area 41 is provided with a first escape exit 42, the evacuation corridor 2 is provided with a first fire door 43, the anteroom 3 is provided with a second fire door 44, the open office area 41 is connected to the evacuation corridor 2 through the first escape exit 42, the evacuation corridor 2 is connected to the anteroom 3 through the first fire door 43, the anteroom 3 is connected to the evacuation stairwell 4 through the second fire door 44, and the descent room 5 is connected to the anteroom 3.

[0028] In this embodiment, a base plate 6 is embedded in the ground of the descent chamber 5. A through-type second escape opening 7 is opened on the upper surface of the base plate 6. Two sets of fixing plates 8 are embedded inside the base plate 6. A first linkage groove 9 is opened on the opposite side of the fixing plate 8. A load-bearing plate 10 is slidably connected inside the first linkage groove 9. A limit plate 11 is fixedly connected inside the first linkage groove 9. A turbine cylinder 12 is rotatably connected through the left side of the limit plate 11. A screw 13 is threadedly connected inside the turbine cylinder 12. The end of the screw 13 away from the turbine cylinder 12 is connected to the limit plate 12. The position plate 11 is fixedly connected. Two sets of gear disks 14 are rotatably connected inside the first linkage groove 9. The gear disks 14 mesh with the turbine cylinder 12. A first bevel gear 15 is integrally formed on the upper surface of the gear disks 14. Second linkage grooves 16 are symmetrically opened on opposite sides of the fixed plate 8. A first straight rod 17 is rotatably connected inside the second linkage groove 16. A second bevel gear 18 is fixedly connected to the outer wall of the first straight rod 17. A connecting rod 19 is provided inside the first linkage groove 9. A third bevel gear 20 and a second bevel gear 18 are fixedly connected to both ends of the connecting rod 19, respectively. The fourth bevel gear 21 meshes with the third bevel gear 20 and the first bevel gear 15. The fourth bevel gear 21 meshes with the second bevel gear 18. A screw block 22 is threaded onto the outer wall of the first straight rod 17. A U-shaped piece 23 is fixedly connected to the upper surface of the screw block 22. A shaft 24 is rotatably connected inside the U-shaped piece 23. A support rod 25 is rotatably connected to the outer wall of the shaft 24. A hinge 26 is rotatably connected to the opposite ends of the two support rods 25. A lever 27 is fixedly connected between the hinges 26. Under normal conditions, the load-bearing plate 10 will cover the second escape hatch. 7. Covering provides safety protection. When it is necessary to expose the second escape opening 7, the gear disk 14 rotates, driving the turbine cylinder 12 to rotate, which in turn moves the screw 13, causing the load-bearing plate 10 to move and expose the second escape opening 7. When the gear disk 14 rotates, the first bevel gear 15 drives the connecting rod 19 to rotate, which in turn causes the second bevel gear 18 and the fourth bevel gear 21 to rotate, causing the first straight rod 17 to rotate, which in turn causes the screw block 22 to move relative to each other, causing the support rod 25 to move upward relative to each other, and then causing the hinge 26 to rise, so that it can be separated from the second escape opening 7.

[0029] In this embodiment, a working groove 28 is provided on the upper surface of the fixing plate 8. A driving gear 29 is rotatably connected inside the working groove 28. A driven gear 30 is meshed with the outer wall of the driving gear 29. A working rod 31 is fixedly connected inside the driven gear 30. A fifth bevel gear 32 is fixedly connected to the outer wall of the working rod 31. The fifth bevel gear 32 meshes with the first bevel gear 15. A safety block 33 is fixedly connected inside the working groove 28. A crossbar 34 is fixedly connected to the left end of the safety block 33. A safety component 35 is slidably connected to the outer wall of the crossbar 34. The safety component 35 is adapted to the driving gear 29. The two sides of the right side of the safety component 35 are... The first workpiece 36 is fixedly connected to the end of the safety block 33. The front and rear ends of the safety block 33 are slidably connected to the safety buckle 37. The left end of the safety buckle 37 is fixedly connected to the second workpiece 38. The first workpiece 36 and the second workpiece 38 are rotatably connected to the safety rod 39. The driving gear 29 drives the driven gear 30 to rotate, which in turn causes the working rod 31 to rotate, which in turn causes the two first bevel gears 15 to rotate, which drives the gear disk 14 to rotate, thereby realizing the rotation of the turbine cylinder 12. The safety buckle 37 is moved to both sides, which drives the safety rod 39 to move, allowing the safety component 35 to move on the crossbar 34 and separate from the driving gear 29, thus realizing the mobility of the driving gear 29.

[0030] In this embodiment, the rappelling chamber 5 is equipped with a rappelling rescue device 45, which is adapted to the lever 27. The rappelling rescue device 45 is a conventional rescue rope that can be hung on the lever 27, and then the person descends.

[0031] In this embodiment, the safety buckle 37 is made of magnet material, and a magnet 46 is fixedly connected inside the working groove 28. The safety buckle 37 and the magnet 46 are attracted to each other. After the safety buckle 37 is moved to both sides, it is attracted and fixed to the magnet 46.

[0032] In this embodiment, the cross-sectional width of the evacuation corridor 2 varies, with a smaller width near the first escape exit 42 and a larger width near the first fire door 43, which facilitates escape.

[0033] According to another aspect of the present invention, a design method for fire evacuation corridors in standard floors of super high-rise buildings is provided, comprising the following steps:

[0034] S1. Construct a widened evacuation corridor 2 near the first fire door 43. The widening of the evacuation corridor 2 near the first fire door 43 provides a buffer space for personnel to escape.

[0035] S2. The personnel escape behavior is set as follows: enter the open office area 41 from the office cubicle 40, enter the evacuation corridor 2 through the first escape exit 42, enter the anteroom 3 through the first fire door 43, and then enter the evacuation stairwell 4 through the second fire door 44.

[0036] S3. When personnel are physically exhausted or need rescue, they should stand in the rappelling chamber 5 and wait for rescue.

[0037] S4. Personnel can install the rappelling rescue equipment 45 and lever 27. Then other personnel can push the safety buckle 37 to both sides, so that it can be attracted to the magnet 46 and at the same time move the safety bar 39, causing the safety component 35 to separate from the drive gear 29. Then the user can rotate the drive gear 29.

[0038] S5, the driving gear 29 drives the driven gear 30 to mesh and rotate, thereby causing the gear disk 14 to rotate, moving the load-bearing plate 10, thus exposing the second escape opening 7, and causing the support rod 25 to be raised, and personnel to quickly descend and escape through the rapid descent rescue equipment 45.

[0039] The working principle of this device is as follows: personnel escape from office cubicles 40 and open office areas 41 through the first escape exit 42, the first fire door 43, the second fire door 44, the anteroom 3, and the evacuation stairwell 4. When personnel become exhausted, they enter the descent chamber 5 to remain. When some personnel need to evacuate, the safety buckle 37 is moved to both sides and attracted and fixed to the magnet 49, which moves the safety bar 39, allowing the safety component 35 to move on the crossbar 34 and separate from the drive gear 29, thus enabling the drive gear 29 to move. Then, the drive gear 29 drives... The driven gear 30 rotates, which in turn causes the working rod 31 to rotate, which in turn causes the two first bevel gears 15 to rotate, driving the gear disk 14 to rotate, thus causing the turbine cylinder 12 to rotate, which in turn causes the screw 13 to move, causing the load-bearing plate 10 to move and expose the second escape port 7. When the gear disk 14 rotates, the first bevel gear 15 drives the connecting rod 19 to rotate, which in turn causes the second bevel gear 18 and the fourth bevel gear 21 to rotate, causing the first straight rod 17 to rotate, which in turn causes the screw block 22 to move relative to each other, causing the support rod 25 to move upward relative to each other, and then causing the hinge 26 to rise, thus allowing it to detach from the second escape port 7.

[0040] All electrical components mentioned in this article are real-world electrical components.
