Method for retrofitting a building with an elevator system, component set for carrying out the method, elevator system and prefabricated shaft for the elevator system

摘要

The invention relates to a method for retrofitting a building with an elevator system 26, a set of components for carrying out the method, an elevator system 26 and a prefabricated shaft 27 for the elevator system 26. The shaft 27 extends over at least two floors 3 and comprises a self-supporting sheet metal box at least one steel plate, which is provided for receiving a car 36 of the elevator installation 26 together with its guides and drive devices. The sheet metal box of the shaft 27 has a profiled cross-section, which in the cross-sectional plane within the sheet metal box forms a cross-sectional area that essentially covers the area required by the car 36 and its guides and drive devices, as well as the area of an elevator platform 35 for bridging a distance between the The method according to the invention for retrofitting a building with such an elevator system comprises the steps of: - prefabrication of the elevator system 26, - making a foundation 14 for the elevator system 26 in front of the front side 1 of the building, - opening the front side 1 of the Building in the width of the staircase 5, - Removal of the intermediate landings 8 and the two-flight staircase 9, - Installation of webs 24 at the level of the main landings 7, which extend horizontally from the main landings 7 to the front 1 of the building and the cross-section of the staircase 5 only partially cover it, in order to leave clear space for a staircase, - installation of a single flight of stairs 22, which connects the individual webs 24 with one another and together with them forms a modified staircase, - setting up the elevator system 26 on the foundation 14, - aligning the elevator system 26 on the foundation 14 and attaching the elevator system 26 to the front side 1 of the building, establishing a connection between the elevator landings 35 and the webs 24 of each floor 3, establishing an access to the elevator landing 35 of the ground floor from outside the building.
