Preferably, a newly-added platform is arranged between the middle platform and the elevator room entrance and exit, and the newly-added platform is used for connecting the fire fighting access and the wall of the old building.

Preferably, the lower half-layer stairs are fixed with the fire fighting access, and the middle platform is detached to improve the clearance height of the fire fighting access.

Preferably, the fire passage is an extension structure of a lower half staircase to an entrance and an exit of the elevator car.

Preferably, the extension structure is a staircase that is either a straight staircase or a spiral staircase.

Preferably, the upper half of the stairs are dismantled by 2-3 levels and used for providing installation space of the reinforcing upright post.

Preferably, the clearance height of the fire fighting access is not less than 2 meters.

Use the technical scheme of the utility model, following beneficial effect has:

(1) in the utility model, the clearance height of the fire fighting channel is ensured to be not less than 2 m by removing the middle platform, and the comfort of entering the home is improved; through setting up newly-increased platform, when guaranteeing fire control passageway's headroom height, improved fire control passageway's support stability again.

(2) The utility model discloses in, set up the enhancement stand in the corner of first floor stair and second floor stair for support the platform of registering one's residence, improved the stability of structure, whole stair transform structure safe and reliable.

In addition to the above-described objects, features and advantages, the present invention has other objects, features and advantages. The present invention will be described in further detail with reference to the drawings.

Drawings

The accompanying drawings, which are incorporated in and constitute a part of this application, are included to provide a further understanding of the invention, and are incorporated in and constitute a part of this specification. In the drawings:

FIG. 1 is a schematic view of a stair reconstruction structure;

the building comprises an upper half layer of stairs, a lower half layer of stairs, a middle platform, an external elevator, an elevator room entrance and exit, an entrance platform, a reinforcing upright post, a door, a fire fighting channel, a new platform, an old building wall and an old building wall, wherein the upper half layer of stairs is 1, the lower half layer of stairs is 2, the middle platform is 3, the external elevator is 4, the elevator room entrance and exit is 5, the entrance platform is 6.

Detailed Description

The embodiments of the invention will be described in detail hereinafter with reference to the accompanying drawings, but the invention can be implemented in many different ways, which are defined and covered by the claims.

Example 1:

referring to fig. 1, a stair retrofitting structure comprises an old stair portion and an add-on portion; the old stair part comprises an upper half-layer stair 1, a lower half-layer stair 2 and a middle platform 3 connecting the upper half-layer stair 1 and the lower half-layer stair 2; the additional installation part comprises an external elevator 4, an elevator room entrance 5, an entrance platform 6 and a reinforced upright post 7; the entrance platform 6 is communicated with the door 8 and the elevator room entrance and exit 5; the elevator room entrance 5 is formed by reforming an old building wall body 11; the reinforcing upright post 7 is arranged at the corner of the upper-half-layer stair 1 and the lower-half-layer stair 2 and is used for supporting the entrance platform 6; the middle platform 3 and the elevator room entrance and exit 5 form a height difference, and a fire fighting channel 9 is arranged to connect the middle platform 3 and the elevator room entrance and exit 5; the elevator car doorway 5 reaches the external elevator 4 through a connecting corridor.
