AI Technical Summary

Technical Problem

The existing methods for constructing elevators in high-rise buildings require additional work and logistics due to the need for prefabricated guide rails with accurate mounting holes, which complicates the process and increases material management and delivery complexities, especially during the 'jump' phase of elevator installation.

Method used

The proposed solution involves on-site perforation of mounting holes for guide rails and rope suspenders, allowing for flexible modification of the jump plan and reducing the need for additional materials, using simple recyclable tools and drilling from the roof of the elevator car or installation platform.

Benefits of technology

This approach simplifies the installation process, reduces material needs, and shortens construction time, enabling elevators to be completed and handed over to customers more quickly with improved site logistics and reduced logistical complexities.

Abstract

An elevator construction arrangement comprises a hoistway (1); an elevator car (10), a counterweight (13), car guide rails (8) for guiding the car, and counterweight guide rails (9) for guiding the counterweight; an elevator hoisting machinery (30) and a suspension roping (31) arranged to suspend the car (10) and the counterweight (13) during construction time use; a protection deck (2) mounted within the hoistway (1) during an elevator installation in the hoistway; a hoist device (6) configured to move the car (10) or at least parts of the car below the protection deck (2), the car being guided on the car guide rails (8); wherein the arrangement comprises at least one guide rail (8; 9) with mounting perforations such as mounting holes made at the construction site for the machinery (30) and / or for at least one rope suspender (32, 32') in connection with an elevator jump. A method for installing an elevator during construction of a building (100).
