In the private staircase group, each staircase connecting two adjacent floors in turn contains at least one The stair run (40) and the platforms (10, 20) at both ends, the stair run (40) and the platforms (10, 20) at both ends are located in the same private stairwell (70). There are only private stairs in the stacked private stairs, but no public stairs, so that there is no connection between the private stairs and the public stairs.

Description

Stacked private stairway

The present invention relates to the staircase structures of multi-story structure for technical field；Particularly, the present invention relates to a kind of structures of longitudinal stack formula private stairway.

Background technique

Often there is the space being difficult to be utilized up and down in the 101575898 various types of architectural stairs of A of [patent document 1] WO/2014/064624 [patent document 2] WO/2014/064625 [patent document 3] CN, as shown in Figure 1, the space of oblique line portion, seems and is difficult to avoid that.Above patent document discloses the method for eliminating the triangle space (spandrels) that traditional stair are difficult to be utilized up and down.The method is summarized as a kind of virtual stairwell: MAXU stairwell by patent document 1 and patent document 2.It is exactly so-called MAXU stairwell as shown in Fig. 2, the vertical pillar region 80 that line of demarcation is surrounded, in the stairwell, both comprising capableing of the public stairs of sensible each floor up and down, the also private stairway comprising being embedded in stairwell.From effect, this cleverly imbeding relation, eliminates the triangle space of traditional private stairway or more between private stairway and public stair.But this imbeding relation also causes the position of private stairway to select to be restricted: private stairway must share a stairwell with public stair.In order to help to understand the space structure of stair, a classification is done to several forms of private stairway here.Symbol and meaning Symbol meaning

P Private, private stairway space

C Common, public stair space

Trigonum above and below Δ stair, it is oblique to represent stair

If the termination of face parallel relation so uses symbols, we are simplified as the most common stair form: private stairway: Δ Ρ Δ (duplex)；Alternatively, Δ Ρ Ρ Δ (three layers of duplex) public stair: AC ... CA can see traditional stair, and private stairway is exactly private stairway, and public stair are exactly public stair, not have the association in space between them.Traditional stairwell is exactly specially to refer to public staircase.Here, it is emphasized that, when describing the space structure of a flight of stairs, Δ is a critically important feature.Staircase structure described in so aforementioned three patent documents is respectively if expressed with symbolic language:

Main feature in sharp document 3: P is regularly alternately present in left and right two is run；Main feature in sharp document 1: P occurs to non-regularity in left and right two is run；Main feature in sharp document 2: floor feature is entirely C with patent document 1, floor below above.

For summary of the invention in order to make no longer to be associated between private stairway and public stair, the present invention proposes a kind of new stair space combination structure.There was only private stairway in claimed stacked private stairway, without public stair.Stacked private stairway described here is made of the private stairway of about one group stack combinations, these private stairways belong at least two building units.One building unit typically refers to a set of compound apartment or compound working space.In order to describe present invention technical solution to be protected, need to propose the concept of a new virtual stairwell: private stairway well.The description of MAXU stairwell in similar patent document 1 and patent document 2, private stairway well is also a vertical pillar space here；Its section is generally rectangular.Its width is generally equivalent to the width of stair, the thickness of the partition wall of additional interval left and right building unit.Its length is equal to the length of a vertical ladder (terrace part including both ends), or is equal to the length of a race (terrace part including both ends) below " L " shape stair.The claimed technical solution of the present invention, which is characterized in that in the private stairway group, each stair for being sequentially connected two adjacent floors all include the platform at least one race stair and both ends；The stair are run and both ends platform is located in the same private stairway well；That of each floor is run between stair, is parallel to each other, is successively equally spaced up and down.It should be noted that parallel equidistant distribution here, is the case where layer height based on floor is fixed value.If the layer height of different floors is inconsistent, the distance between these adjacent stair should also be as matching. If the present invention is described with symbolic language above-mentioned, need further to refine

Further solution of the invention is elaborated in embodiment part below in conjunction with attached drawing.

Traditional staircase structure figure is shown in Detailed description of the invention Fig. 1.Fig. 2 is a kind of private stairway that patent document 1 (WO/2014/064624) is proposed and public stair are integrated in schematic diagram in a MAXU stairwell.A kind of basic structure of the invention: the pattern that is successively interspersed of private stairway is shown in Fig. 3.In figure, A-1 and A-2 respectively represent the upper layer and lower layer of building unit A；B-1 and B-2 respectively represents the upper layer and lower layer of building unit B；C-1 and C-2 respectively represents the upper layer and lower layer of building unit C；And so on.Another structure of the invention: the non-pattern that is successively interspersed of private stairway is shown in Fig. 4.In figure, A-1 and A-2 respectively represent the upper layer and lower layer of building unit A；B-1, B-2 and B-3 respectively represent three layers of upper, middle and lower of building unit B；And unit C only has one layer, the private stairway of oneself, the upper surface of it are not the first layers of cells D (total number of plies is not indicated).Fig. 5 is a kind of schematic diagram that vertical ladder structure is run using two.Corresponding with Fig. 5 reversed two schematic diagrames for running vertical ladder structure are shown in Fig. 6.Fig. 7 is shown two in Fig. 5 and Fig. 6 and runs the spatial relationship schematic diagram that vertical ladder or more is superimposed. Fig. 8 increases load-bearing pillar on the basis of Fig. 7, at the both ends of halfpace.Fig. 9 increases load-bearing pillar on the basis of Fig. 7, in one end of halfpace.Here, private stairway is by the way of being successively interspersed.The difference of Figure 10 and Fig. 9 is that private stairway is non-and is successively interspersed.The schematic top plan view of Fig. 9 is shown in Fig. 11.The halfpace of Figure 12, which is shown, is " L " shape stair increases the schematic top plan view of load-bearing pillar.The situation that the load-bearing pillar in Figure 12 has fan shaped cross section is shown in Figure 13.

Embodiment embodiment one: the pattern diagram 3 that is successively interspersed of " L " shape private stairway is the schematic diagram of this Distribution Pattern.It is belonging respectively to the private stairway of left and right sides unit successively alternately vertical distribution.In figure, A-1 and A-2 respectively represent the upper layer and lower layer of building unit A；B-1 and B-2 respectively represents the upper layer and lower layer of building unit B；C-1 and C-2 respectively represents the upper layer and lower layer of building unit C；D-1 represents the lower layer of building unit D；And so on.If the stair space structure symbolic language above-mentioned in private stairway well 70 is described, obtain as follows:

Embodiment two: the non-pattern diagram 4 that is successively interspersed of " L " shape private stairway is the schematic diagram of this Distribution Pattern.It is belonging respectively to the private stairway of left and right sides unit successively alternately vertical distribution.In figure, A-1 and A-2 respectively represent the upper layer and lower layer of building unit A；B-1, B-2 and B-3 respectively represent three layers of upper, middle and lower of building unit B；And unit C only has one layer, the private stairway of oneself, the upper surface of it are not the first layers of cells D (total number of plies is not indicated).If the stair space structure symbolic language above-mentioned in private stairway well 70 is described, obtain as follows:

Note that there are two P here_B, but there is no P_c.Figure 12 shows further the positional relationship of " L " shape private stairway various pieces and private stairway well 70.This relationship is also applied for embodiment one.The platform 10 and 20 of a race and its both ends that lower layer's flooring and halfpace 20 are connected in figure is all located in the same private stairway well 70；And another race is then located at outside private stairway well 70, lower one end is closely connect with private stairway well 70, and higher one end connects upper floor.For " L " shape private stairway, the height of halfpace determines the space comfort level below a race stair above.So the vertical range of halfpace 20 and lower layer's flooring is more preferably greater than 2 meters.

Embodiment three: two run vertical ladder it is layer-by-layer or it is non-be successively interspersed pattern diagram 5, the situation for running vertical ladders composition private stairway wells 70 using two is shown in Fig. 6 and Fig. 7. As shown in Figure 5 and Figure 6, two race vertical ladders and three landings 10,20,30 are all located in the same private stairway well 70；Stair run 40 connecting platforms 10 and 20.Fig. 7 do not show it is each two race vertical ladder directionality: that is belong to Fig. 5 or Fig. 6 which of.When Fig. 5 and vertical ladder shown in fig. 6 are successively alternately repeated appearance in stairwell, the pattern being successively interspersed just is formed.Otherwise, the non-pattern being successively interspersed just is formed.

Example IV: two walls run between the quadrangle support column stair activity of vertical ladder halfpace are not vertical continuous, therefore cannot act as load bearing wall.In order to provide enough support forces to staircase structure, it is necessary to the load-bearing pillar that setting is led directly to up and down in position.A kind of situation of the quadrangle setting support column 60 of halfpace that vertical ladder is run two is shown in Fig. 8.Since halfpace is located at the middle part of stair, here by support column setting, the span for the horizontal gird being connected with support column can be made to be maintained in the range of necessity.
