Three-section stairs with functions of four-section stairs

Abstract

The invention provides three-section stairs with functions of four-section stairs. The three-section stairs comprise left stairs, intermediate stairs and right stairs, which are adjacent to one another. The inclined direction of the left stairs is the same as that of the right stairs and opposite to that of the intermediate stairs; the vertical height of the left stairs is the same as that of the right stairs, the summation of the vertical heights of the left stairs and the intermediate stairs equals to floor height of a building. The left stairs of odd-numbered floors and the right side stairs of even-numbered floors and all the intermediate stairs form consecutive stairs from top to bottom (three stairs type doglegged stairs for short), the three stairs type doglegged stairs are isolated from other stairs by a wall surface, and their functions are the same as regular doglegged public stairs; at this time the lift stairs of the even-numbered floor could be indoor stairs of a unit of the even-numbered floor, and the right stairs of the odd-numbered floor could be indoor stairs of a unit of the odd-numbered floor. Regular indoor stairs take up two-floor surface, and one half of space is vacant. A single-flight (section) in above three stairs type doglegged stairs makes use of vacant space of regular indoor stairs, when being used as pubic stairs, the building area is decreased by 50% compared with that of regular public stairs; therefore, three-section stairs have substituted the four-section stairs required by regular design.

Description

【Technical field】 [0001] The invention relates to a method for designing a three-dimensional space, in particular to a stair design that saves stair space and improves the efficiency of stair use. 【Background technique】 [0002] Existing 1 staircase 2 households, 1 public staircase can only serve 2 households per floor, and the utilization rate of public staircases is not high. For this reason, there is a design method in which 1 ladder and 3 households pass through the residential building vertically. The public staircase of the residential building designed according to this method serves 3 households on average on each floor, and the households are longitudinally connected. Therefore, the same number of households with 1 ladder and 2 Compared with residential buildings, the construction area of ​​its public stairs has been saved by 1 / 2. [0003] On the other hand, some of the 1-stair 3-family houses designed according to the above method are as follows: figure 1 As show...
