The present invention relates to a contilever-type building evacuation structure, and more particularly, to a contilever-type building evacuation structure, which is implemented in a contilever method and can evacuate quickly and safely in the event of a fire.

In general, buildings of a certain size or larger are equipped with an evacuation device for evacuation in case of disasters such as fire or earthquake. The elevator is installed and operated on a window or veranda, and when it is difficult to use the stairs or elevator in case of a disaster, evacuees must evacuate to the outside through the elevator.

However, it is not easy to evacuate quickly because the evacuator has to evacuate while hanging on a rope that is released slowly. In addition, in the case of the elderly, children, and women, there is a situation in which they refuse to use the bracing machine due to limitations in physical strength or fear of heights.

In order to solve this problem, the need for a technology that allows evacuation from the upper floor of the building to the lower floor has emerged.

The first and second centrifugal brakes 441 and 541 are axially coupled with the first and second winch parts 442 and 542 inside the brake drum and have a built-in brake shoe assembly that moves toward the brake drum by centrifugal force. , It is linked to the rotation speed of the first and second winch parts 442 and 542 to provide a braking force so that the first and second winch parts 442 and 542 are rotated slowly. Since these first and second centrifugal brakes 441 and 541 are configurations generally used in the art, further detailed description will be omitted.

The first and second winches 442 and 542 are, as shown in FIG. 5 , the first and second centrifugal brakes 441 and 541 and the first and second winches 442a and 542a axially coupled. And, the first and second small winches (442a) (542a) smaller than the first and second small winches (442c) (542c), and the first and second small winches (442a) (542a) and the first and second small winches ( It includes first and second inclined winches 442b and 542b connecting the 442c and 542c. That is, the first and second winch parts 442 and 552 are large-diameter first and second large winches (442a) (542a), and small-diameter first and second small winches (442c) (542c), and the second It is to have the first and second inclined winches (442b) (542b) connecting the first and second large winches and the first and second small winches. For example, if it is assumed that the diameter of the first and second small winches 442a and 542a is around 15cm, the first and second small winches 442c and 542c will be around 10cm. Spiral grooves are formed on the surfaces of the first and second large winches (442a) (542a), the first and second inclined winches (442b) (542b) and the first and second small winches (442c) (542c). Accordingly, the first and second elevating wires 444 and 544 and the first and second return wires 445 and 545 may be wound a plurality of times without overlapping.

The first and second weights 443 and 543 are raised and lowered along the first and second guide rail grooves 427 and 527 formed in the first and second column bodies 421 and 521 . At this time, in order to allow the first and second weights 443 and 543 to move up and down smoothly without shaking during the lift, the first and second weights 421 and 521 are attached to the side of the first and second weights 443 and 543. ) The first and second guide bearings 443a and 553a for bearing movement along the first and second guide rail grooves 427 and 527 formed on the side are installed.

The first and second elevating wires 444 and 544 have one end fixed to the first and second winch parts 442 and 542, and strictly large-diameter first winch 442a, 542a, and rotate in a clockwise direction. After being wound, the other end is connected to the first and second lifting boards 430 and 530 . The first and second return wires 445 and 545 have one end fixed to the first and second winch parts 442 and 542, strictly large-diameter first winch 442a, 542a, and counterclockwise After being wound in the direction, the other end is connected to the first and second weights 443 and 543 . That is, one end of the first and second elevating wires 444 and 544 and the first and second return wires 445 and 545 are fixed to the first winch 442a and 542a while the first and second elevating wires 444 and 544 are fixed to the first and second elevating wires. The wires 444 and 544 are wound in a clockwise direction, and the first and second return wires 445 and 545 are wound in a counterclockwise direction.

By this connection structure, according to the direction in which the first and second winch parts 442 and 542 are rotated, among the first and second elevating wires 444 and 544 and the first and second return wires 445 and 545 One rises and the other descends. At this time, one end of the first and second elevating wires 444 and 544 and the first and second return wires 445 and 545 are fixed to the first and second winches 442 and 542 in a clockwise direction and Since it is wound in the counterclockwise direction, when the first and second winch parts 442 and 542 are rotated, the first and second elevating wires 444 and 544 and the first and second return wires 445 and 545 are first , to prevent idle rotation in the 2 winch unit (442, 542).

If the first and second elevating wires 444 and 544 and the first and second return wires 445 and 545 are connected as one body, the first and second winches 442 and 542 are wound several times. In the case of the form, the first and second winch parts 442 when the first and second winch parts 442 and 542 suddenly rotate or when an evacuee with a heavy weight boards on the first and second lifting boards 430 and 530. ) (542) surface and the first and second elevating wires 444, 544 and the first and second return wires 445 and 545 may slide in between the surface and may spin in vain. Therefore, in order to prevent the phenomenon of spinning, one end of the first and second elevating wires 444 and 544 and the first and second return wires 445 and 545 are connected to the first and second winch parts 442 and 542. It is very important to be fixed on

The first and second winches 442 and 542 are the first and second large winches 442a, 542a, the first and second inclined winches 442b, 542b and the first and second small winches 442c, 542c ), the torque applied to the rotation shaft of the first and second winch parts 442 and 542 is varied. For example, when the first and second return wires 445 and 545 are released from the first and second large winches 442a and 542a of large diameter, the rotation shaft of the first and second winch parts 442 and 542 The torque applied to the is the largest, and when the first and second small winches 442c and 542c of small diameter are released, the torque applied to the rotation shaft of the first and second winches 442 and 542 is the smallest. This means that the magnitude of the torque varies depending on the position where the first and second return wires 445 and 545 are wound or unwound.

To explain this in more detail, when the first and second lifting boards 430, 530 descend to the bottom of the tilever as the evacuee boards, the first and second weights 443 and 543 are formed by the first and second pillars ( After moving to the upper side of the 420 and 520, when the evacuee evacuates, the first and second weights 443 and 543 descend by their own weight and lift the first and second lifting boards 430 and 530 at the initial stage. raise to position.

At this time, at the initial point in time when the first and second weights 443 and 543 descend from the upper side of the first and second pillars 420 and 520, the first and second return wires 445 and 545 are first , is released from the second winch (442a) (542a), and at this time, since the torque is the largest, the first and second weights (443) (543) are quickly descended, and accordingly, the first and second lifting boards (430) ( 530) rises rapidly.

Thereafter, at the point in time when the first and second weights 443 and 543 pass the middle side of the first and second pillars 420 and 520 , the first and second return wires 445 and 545 have an inclined surface. The first and second inclined winches 442b and 542b are released while passing, and in this process, the first and second weights 443 and 543 gradually and slowly descend because the torque is gradually reduced. In this case, the ascending speed of the first and second lifting boards 430 and 530 gradually decreases.

And when the first and second weights 443 and 543 pass the lower side of the first and second pillars 420 and 520, the first and second return wires 445 and 545 are first and second It is released while passing the small winches (442c) (542c), and in this process, the first and second weights (443, 543) are slowly descended because the torque is the smallest. In this case, the ascending speed of the first and second lifting boards 430 and 530 becomes the smallest.

That is, the first and second return wires 445 and 545 are moved from the first and second large winches 442a and 542a to the first and second small winches 442c and 542c and the torque that is changed in the process of loosening. As a result, the descending speed of the first and second weights 443 and 543 gradually decreases, and in conjunction with this, the ascending speed of the first and second lifting boards 430 and 530 is the largest when ascending from the floor-side contilever. The closer you get to the ceiling-side contilever, the smaller it gets.

This operation mechanism is equally applied even when the evacuator descends while riding on the first and second lifting boards 430 and 530, and accordingly, The evacuator descends rapidly at the beginning and then slowly descends, thereby preventing the evacuator from falling due to the impact from the floor-side contilever. In addition, when the first and second lifting boards 430 and 530 return to the upper side contilever, they rise rapidly at the beginning and then slowly descend from the upper side contilever side, so that damage due to collision can be prevented.
