How to add an elevator to an elevated floor: full analysis of technical difficulties and solutions
In recent years, with the advancement of renovation of old communities and urban renewal, the installation of elevators on overhead floors has become a hot topic. This article will combine the hot content of the entire network in the past 10 days, analyze the technical difficulties, solutions and practical cases of installing elevators on overhead floors, and provide readers with a structured reference.
1. Statistics of hot topics on the entire network in the past 10 days
| Topic keywords | Search volume (10,000 times) | Discussion platform | heat index |
|---|---|---|---|
| Renovation of old residential areas | 45.6 | Weibo, Zhihu | ★★★★★ |
| Elevator installation policy | 32.1 | Government official website, headlines | ★★★★☆ |
| overhead layer structure | 18.9 | Professional forum, B station | ★★★☆☆ |
| Elevator design plan | 26.7 | Douyin, Xiaohongshu | ★★★★☆ |
2. The core difficulty of adding an elevator to an elevated floor
1.Structural load-bearing issues: The original design of the overhead layer did not consider the elevator load, so the structural safety needs to be recalculated.
2.Space layout restrictions: The height of most overhead floors is less than 3 meters, and innovative designs are needed to reduce the height of the elevator shaft.
3.Pipeline migration is complicated: The original water, electricity and gas pipelines need to be re-planned and construction is difficult.
4.Difficulties in neighborhood coordination: Low-rise residents’ concerns about lighting and noise need to be properly addressed.
3. Comparison of mainstream solutions
| Plan type | Advantages | Disadvantages | Applicable scenarios | Cost estimate (10,000 yuan) |
|---|---|---|---|---|
| External elevator | Construction is fast and does not affect the interior | Affect the facade | Brick-concrete structure residence | 25-35 |
| Embedded elevator | High aesthetics | Part of the wall needs to be demolished | frame structure house | 40-50 |
| Split-level entry design | save space | Stairwell needs to be renovated | Elevated floors with insufficient floor height | 30-45 |
4. Application of innovative technologies in 2023
1.micro traction system: The size of the shaft can be reduced to 1.2m×1.5m to solve the problem of insufficient space.
2.Steel structure integrated base: Achieve quick installation in 3 days, load-bearing up to 1 ton.
3.Photovoltaic powered elevator: Reduce operating energy consumption, suitable for areas with sufficient sunshine.
5. References to successful cases
| Project location | Construction era | solution | construction period | resident satisfaction |
|---|---|---|---|---|
| Jing'an District, Shanghai | 1995 | Plug-in + staggered entry | 45 days | 92% |
| Guangzhou Tianhe District | 1988 | Embedded + steel structure | 60 days | 88% |
6. Implementation Process Guide
1.Preliminary evaluation: Entrust a professional organization to conduct structural testing and feasibility analysis.
2.Scheme design: Select a unit with special equipment design qualifications to issue drawings.
3.Approval process: It needs to pass the joint review of planning, fire protection, quality supervision and other departments.
4.construction management: It is recommended to adopt the EPC general contracting model to avoid multi-party coordination.
Conclusion:Installing an elevator on an elevated floor is an important measure to improve the quality of living, and requires comprehensive consideration of technical feasibility and community harmony. With the implementation of the Barrier-free Environment Construction Law, it is expected that there will be a new wave of renovations in the next three years, and residents are advised to plan and prepare in advance.
