Description

Technical Field

[0001] This utility model relates to the field of elevator installation technology, and in particular to a straight-level floor access structure for elevator installation. Background Technology

[0002] As people's living standards continue to improve, the installation of elevators in older residential communities is becoming increasingly popular, with more and more outdoor elevators being installed. Please refer to [link / reference]. Figure 1 Current elevator installation projects typically involve entry through the stairwell, usually only half a floor. This means connecting to the stairwell landing 101 via a newly built corridor, then climbing half a flight of stairs 102 to reach the entrance platform 103. This method requires climbing or descending half a flight of stairs, which is extremely inconvenient for people with mobility issues and fails to achieve the desired effect of elevator installation. Therefore, a direct, level entrance structure is needed that is easy to construct, does not affect elevator use during construction, and provides a level, direct entry effect upon completion.

The steel structure steps 35 are located between the inner connecting steel beams 33 and the outer connecting steel beams 34. The multi-level horizontal elevator corridor 2 and the staircase 3 alternately form a Z-shaped structure. Preferably, a steel structure corridor 5 is provided at the car stop of the staircase 3 and the elevator shaft 1. The steel structure corridor 5 is horizontally connected to the horizontal elevator corridor 2, and the steel structure corridor 5 facilitates the transportation of materials during the renovation. Preferably, guardrails (not shown in the figure) are provided on the outside of both the horizontal elevator corridor 2 and the staircase 3. The guardrails are welded to the bottom of the outer connecting steel beam 34 and the bottom of the inner steel structure beam 22.

[0027] For more details, please refer to Figure 4 , Figure 5 and Figure 6 The horizontal elevator corridor 2 includes an outer original concrete floor beam 21, an inner steel structure beam 22, multiple longitudinal steel beams 23, and multiple corridor floor slabs 24. One end of the inner steel structure beam 22 is connected to the steel structure corridor 5, and the other end is connected to the floor surface of the entrance door platform 4 of each resident. The multiple longitudinal steel beams 23 are evenly distributed between the inner steel structure beam 22 and the original concrete floor beam 21. Steel beams 25 are installed between the longitudinal steel beams 23, between the longitudinal steel beams 23 and the steel structure corridor 5, and between the longitudinal steel beams 23 and the floor surface of the entrance door platform 4 of each resident.

[0030] This utility model is implemented through the following steps during construction and installation:

[0031] 1. First, install elevator shaft 1 and set up a steel structure corridor 5 to connect with the original building's structural columns, so that the steel structure corridor 5 is flush with the original entrance door platform 4 of each floor. At this time, the elevator car of elevator shaft 1 can be used normally and serve as a vertical transportation tool for the renovated stairwell. At this time, the original stairwell is not modified.

[0032] 2. Modify the original concrete staircase 31 from top to bottom. Erect scaffolding under the original concrete staircase 31 that needs to be removed, and enclose it with formwork to prevent falling stones and other debris from injuring people.

[0033] 3. At the same time, use scaffolding to support the ladder beam 311 of the original 1 / 2 of the original concrete staircase 31 that needs to be retained, to prevent the lack of support after the other end of the ladder beam 311 is chiseled away, which would cause safety hazards. The construction waste generated from the demolished staircase will be removed by the installed elevator.

[0034] 4. Add an inner steel structure beam 22, and then add a steel column 32 on the inner steel structure beam 22. The lower end of the steel column 32 is welded and fixed to the inner steel structure beam 22, and the upper end of the steel column 32 supports the original ladder beam. The scaffolding can be removed only after the support is completed.

[0035] 5. Multiple longitudinal steel beams 23 are added between the original concrete floor beam 21 and the internal steel structure beam 22. Steel beams 25 are installed between adjacent longitudinal steel beams 23, between longitudinal steel beams 23 and the steel structure corridor 5, and between longitudinal steel beams 23 and the floor slabs of each resident's entrance platform 4. Then, the corridor floor slab 24 is laid to form a horizontal elevator corridor 2. At this point, the removal of the staircase on one floor and the construction of the horizontal elevator corridor 2 are complete. People can use the elevator via the horizontal elevator corridor 2 and the steel structure corridor 5. This process is controlled within one day to ensure that residents of this floor are not affected when leaving early or returning late.

[0036] 6. The staircases were demolished sequentially from top to bottom, and a horizontal elevator corridor 2 and a steel structure corridor 5 were constructed. Simultaneously, an internal connecting steel beam 33, an external connecting steel beam 34, and a steel structure step 35 were added at the break point of the original concrete staircase 31, forming a staircase 3 connecting the steel structure staircase to the original concrete staircase 31. The lower end of staircase 3 connects to the horizontal elevator corridor 2, forming an effective evacuation route. After the main renovation of the stairwell is completed, tiles can be laid on the horizontal elevator corridor 2 and the steel structure corridor 5. At this point, all renovation work is complete.

[0037] This utility model achieves level access to the apartment by modifying the original stairwell, removing half of the original staircase, and adding a horizontal elevator corridor, steel columns, internal connecting steel beams, external connecting steel beams, and steel structure steps. The structure of this utility model is easy to construct, does not affect the use of the elevator during construction, and achieves the effect of level access upon completion.
