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 isolatedfrom 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 t he 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

A kind of 3 sections stair with 4 sections stair functions

[technical field]

The present invention relates to a kind of method for designing of solid space, particularly about saving the staircase design of stair space, raising stair service efficiency.

[background technology]

Existing 1 terraced 2 family dwelling houses, 1 public stair can only be served 2 families for every layer, and public stair utilization rate is not high.For this reason, there are a kind of 1 terraced 3 families vertically to connect the method for designing of residential building, serve 3 families for average every layer by its public stair of residential building of this method design, and vertically connect in every family, therefore, compare with 1 terraced 2 family residential buildings of identical amount, the building area of its public stair has saved 1/2.

On the other hand, in She Ji the 1 terraced 3 family dwelling houses, have as shown in Figure 1 as stated above, 1 the two public stair 110 that run are arranged; Odd-level in public stair left side has 1 one to run stair 120, and the even level on public stair right side has 1 one race stair 130 in addition, and they constitute the indoor staircase of odd-level and the middle wrong half storey of even level unit respectively.More than add up to, amount to 4 sections stair.And above-mentioned indoor staircase is similar with conventional indoor staircase, accounts for two layers of floor, and wherein the space of half is idle, needs to improve.

[summary of the invention]

Shown in Fig. 2 (a), 3 sections stair of the present invention comprise the platform 232,233,234 and 235 at platform 222,223,224 and 225, right side stair and the two ends thereof at the left side stair that adjoin mutually and the platform 212,213,214 and 215 at two ends, middle stair and two ends thereof.

The incline direction of left side stair 217 and right side stair 237 is identical, vertical height is also identical; The incline direction of left side stair 217 and middle stair 227 is opposite, and the vertical ladder height addition of the vertical height of left side stair 217 and middle stair 227 equals the floor height of its place building.

In above-mentioned whole stair and platform thereof, constitute a continuous from top to bottom stair space (be called for short 3 ladder types 2 and run stair) with the lower part:

The left side stair of odd-level and two ends platform 213,215 thereof,

The right side stair of even level and two ends platform 232,234 thereof,

Middle stair and two ends platform 222,223,224,225 thereof.

Shown in Fig. 2 (b), to separate with metope between above-mentioned 3 ladder types, 2 race stair and other stair, then it can make the usefulness of public stair, this moment the left side stair of even level and the indoor staircase that two ends platform 212,214 constitutes even level staggered floor unit B, D respectively thereof, the right side stair of odd-level and two ends platform 233,235 thereof constitute the indoor staircase of odd-level staggered floor unit A, C respectively.

In sum, the present invention has satisfied two in the residential building shown in Figure 1 with 3 sections stair and has run each 1 indoor one function of running stair, amounting to 4 sections stair in public stair and the mistake half storey unit, both sides thereof, and 1 race (section) that promptly above-mentioned 3 ladder types 2 run in the stair has utilized space idle in the conventional indoor staircase shown in Figure 1.

[description of drawings]

Fig. 1 vertically connects the residential building schematic diagram for a kind of 1 terraced 3 families, wherein the indoor space of 3 resident families half storey that all interlaces.

Fig. 2 is a kind of space schematic diagram with 3 sections stair of 4 sections stair functions of the present invention.

Fig. 3 is that 3 sections stair of the present invention vertically connect the application in the residential building at 1 terraced 3 families shown in Figure 1.

[specific embodiment]

Fig. 3 has an embodiment of 3 sections stair of 4 sections stair functions for the present invention, wherein (a) is the bottom plane, (b) is 2 layer planes, (c) is 3 layer planes, (d) is the top layer plane.When the number of plies of building during greater than the number of plies of present embodiment, above-mentioned (b) and (c) then become the typical floor plan of even level and odd-level respectively.

The space, lower left 315 of the space, upper left side 310 of Fig. 3 (a) and Fig. 3 (b) and the indoor staircase 319 that is connected them are the same E of resident family, the space, lower left 335 of the space, upper left side 330 of Fig. 3 (b) and Fig. 3 (c) and the indoor staircase 339 that is connected them are the same G of resident family, analogize for surplus time.

The middle superjacent air space 410 of Fig. 3 (b) with among the figure down side space 415 and the indoor staircase 419 that is connected them be the same P of resident family, the middle superjacent air space 420 of Fig. 3 (c) with side space 425 and the indoor staircase 429 that is connected them are the same Q of resident family down among the figure.

The public stair of each floor are as follows:

From the public stair of underground half storey to 1 layer is 510 of Fig. 3 (a),

From 1 layer to 1.5 layers public stair be Fig. 3 (a) 610 and Fig. 3 (b) 710,

From 1.5 layers to 2 layers public stair is 720 of Fig. 3 (b),

From 2 layers to 2.5 layers public stair be Fig. 3 (b) 730 and Fig. 3 (c) 810,

From 2.5 layers to 3 layers public stair is 820 of Fig. 3 (c),

From 3 layers to 3.5 layers public stair be Fig. 3 (c) 830 and Fig. 3 (d) 910.

It should be noted that among Fig. 1 the idle space between two indoor staircase, in the embodiment of the invention shown in Figure 3, be used as public stair.As shown in Figure 3, with temporary location in the neighbouring stair of indoor staircase be public stair.

In sum, present embodiment has satisfied with 3 sections stair and designs needs two routinely and run in the wrong half storey of public stair and both sides thereof the unit each 1 indoor one and run stair, the function of 4 sections stair altogether, and the building area of public stair only is 1/2 of conventional public stair.

More than by example principle of the present invention and spirit have been described, various increases and decreases, distortion and replacement that the present invention is carried out are as the present invention being used for the situations such as building beyond the dwelling house, all in protection of the present invention.
