Outdoor platform evacuation system for vertical transportation trunk and branch conversion of high-rise building

Abstract

The invention discloses an outdoor platform evacuation system for vertical transportation trunk and branch conversion of a high-rise building and relates to a high-rise building evacuation system. The outdoor platform evacuation system adopts a structure with a vertical trunk system and all building subunit branch systems which are combined together. An independently closed central core cylinder-shaped trunk system is provided with a dual-car elevator. Each branch system is provided with stairs and conventional elevators. A transportation conversion platform is arranged at each tower of the high-rise building. Each subunit section is provided with outdoor refuge platforms and is provided with outdoor evacuation refuge platforms at intervals. Two-floor outdoor refuse platforms are arranged in the tower with building height of more than 300m at an interval of 100m to connect all building unit planes, i.e. independent building subunits are arranged in a plane at an interval of approximate twenty floors. Elevators and stairs of each building subunit are independently arranged. An over-hoisting space for an elevator and an elevator machine room are arranged in spaces at corresponding height of each 2-floor refuge platform. The outdoor platform evacuation system overcomes the contradiction that the efficiency of fire rescue and personnel evacuation within short time and the utilization ratio of standard-floor tower usable area cannot be well balanced.

Description

technical field [0001] The invention relates to an evacuation system for a high-rise building, in particular to an outdoor platform evacuation system for converting a vertical traffic trunk and a branch of a high-rise building. Background technique [0002] Currently, evacuation stairs are the most commonly used in super high-rise buildings. The evacuation time is long and the distance is long. When tens of thousands of people travel vertically for a long time, they may encounter dangers such as smoke and fire. Hurt. People who have been accustomed to take the elevator up and down have to walk down from very high floors at once, and many people's bodies will not be able to bear it; in addition, the use of stairs to evacuate the safe evacuation of the elderly and disabled people in super high-rise buildings has also begun. Appear; Especially when people in the super high-rise building are all swarming down from the corridor, tens of thousands of people are crowded in the...

Contents of the invention

[0005] The purpose of the present invention is to provide an outdoor platform evacuation system for the conversion of vertical traffic trunks and branches of high-rise buildings. The height is solved by the method of shuttle elevator conversion to solve the problem of the height limit of the elevator at one time. In the case of not increasing the number of elevator shafts in the tower, the number of ordinary elevators is increased several times relative to the number of sections of the refuge platform, which improves the elevator capacity and solves the problem. Contradictions between short-term evacuation of personnel and the utilization rate of the standard floor tower
