Multi-stage barrier-free entry and outdoor installation of elevators on the large half-floor platform

Abstract

The present invention proposes a large half-floor platform with multi-segment barrier-free access to the outdoors to hang additional elevators. The elevators are arranged outside the old building, and the stairs on both sides are reserved. On the side of the stairs with steps at the same height as the elevator door platform, there are three or more sections of road and staircase traffic infrastructure with different characteristics between the user door platform and the elevator door platform, such as flat walkways, ramps with different slopes, stairs and many more. The effect of the present invention is: the slope ratio of the main ramp is greatly reduced, the main ramp is smoother, and the problem of wheelchairs going up and down the stairs is completely solved; the elevator walkway in front of the living room is not built, and the problem of the elevator walkway blocking the daylighting of the living room is solved; The original gate is used instead of opening a new gate, the original layout of the living room will not be affected, and the living room does not need to be renovated.

Description

【Technical field】 [0001] The invention relates to the field of elevator construction, in particular to an elevator installed in an old multi-storey building. 【Background technique】 [0002] Many multi-storey residential buildings and other buildings built in the early years (abbreviation: old buildings) did not have elevators, which caused a lot of inconvenience to users' daily life, especially for the elderly and people in wheelchairs. With the development of the economy, people are pursuing better living conditions. In recent years, it has become a trend to require the installation of elevators to improve their lives. [0003] Studies have shown that many elderly people will feel strenuous and difficult when climbing the stairs with a height of more than 1 meter, and they need to rest for a while before continuing to climb the stairs. Most of the elevators installed outside the existing buildings are that the elevator opens the door on the half-floor platform of the stair...

Problems solved by technology

Because the slope of the original stairs is usually very large, the slope ratio is usually about 50%. After it is transformed into a ramp, the slope of the ramp is the same as that of the original stairs. walk

[0005] The CN201810507193 patent application proposes a technical scheme for setting a barrier-free entry ramp between the elevator corridor and the floor resident entry platform, and designs that the entry position of the elevator exit is determined at 180-240cm below the conversion platform, so that the elevator exit position The method of forming a small range of height difference with the households on the corresponding floors reduces the height of the entrance slope and reduces the slope ratio of the barrier-free entry slope; however, it only sets a barrier-free entry slope. The scheme seriously wastes part of the height of the entrance slope. The slope ratio of the barrier-free entrance slope is still relatively large. The wheelchair can barely walk on the relatively large slope, but it is actually not feasible to easily drive the wheelchair. sex

The specific calculation of the waste height is as follows: Usually, the length of one side of the double-run half-fold staircase is 3 meters, the width (that is, the longitudinal length) of the stair conversion platform at the half-floor position is 1.2 meters, and the thickness of the outer wall of the stair conversion platform is 0.3 meters. , a total of 4.5 meters, if it can be directly connected to the elevator corridor outside the stair conversion platform, the planar length of the barrier-free entry ramp is 4.5 meters (otherwise, the planar length of the entry ramp will be longer); The height of the location can reduce the slope ratio of the barrier-free entrance slope, but this height is limited and is very valuable, because the height of the entrance to the elevator exit is limited by the crossbeam of the conversion platform of the half-floor staircase, which is located on the half-floor staircase The junction of the conversion platform and the stairs, therefore, only the height of the entrance slope at the stair position (3m) is a useful height, while the height of the entrance slope at the stair conversion platform and the position of the outer wall (1.5m) is useless and wasteful , it can be seen that the height of waste accounts for one-third, 1.5÷4.5=1 / 3, it is really wasteful
