Maxu stairs

Abstract

A combined staircase for high rise buildings, comprising: public staircases (711, 711', 712, 721，721', 722, 811, 812, 821, 822, 831, 832, 841, 842, 852, 852) and private staircases (181, 182, 281, 282, 381, 382, 383, 384, 581, 582) in a MAXU stairwell (80). Each layer contains a left area, a middle area, and a right area. The combined staircase is divided into an upper and a lower portion. Each portion contains at least two floors. The left, middle, and right areas of a lower portion are all public areas and do not contain private staircases (181, 182, 281, 282, 381, 382, 383, 384, 581, 582). Each floor in an upper portion contains only one area, between the left and right areas, that consists of a private staircase (181, 182, 281, 282, 381, 382, 383, 384, 581, 582), and the other area is a public staircase (711, 711', 712, 721, 721', 722, 811, 812, 821, 822, 831, 832, 841, 842, 851, 852). The combined staircase conserves the area occupied by public staircases (711, 711', 712, 721, 721', 722, 811, 812, 821, 822, 831, 832, 841, 842, 851, 852) in high rise buildings.

Description

technical field [0001] The present invention relates to architectural stairs, and in particular to integrated stairs, or MAXU stairs. MAXU stairs consist of private and public stairs that are tightly integrated. Background technique [0002] Common stairs in multi-storey buildings allow people to reach various floors by stairs. There are also internal duplex units in some multi-story buildings, with two-story duplexes as the mainstream. These internal duplex units have their own private stairs that cannot be used by people outside the unit. [0003] figure 1 is a schematic diagram of this building. The stair runs (811, 812, 821, 822, 831, 832, 841 and 842) of the utility stairs, and the landings connected to them, are constructed in a vertical, columnar space called the stairwell 800. figure 1 Also shown is four double-storey duplex units, each with its own door and private staircase. People who enter the unit 30 can reach the upper floor 32 from the lower floor 31 thr...

AI Technical Summary

Problems solved by technology

Above the stairs, there is also a triangular space 52, almost completely wasted

For "L" shaped or "U" shaped stairs, the existence of the intermediate landing makes the waste even worse, because in addition to the triangular spaces 51, 52 and 53, the space 54 on the intermediate landing is completely wasted, and the space 55 under the landing is also completely wasted. Often the height is not enough and it is not easy to use

The same waste exists in three-story duplex units, such as figure 2 shown
