Description

Technical Field

[0001] The invention relates to the technical field of modular elevator installation, and in particular to a method for installing a modular elevator in an existing building. Background Art

[0002] Earlier buildings built in the last century usually only had staircases and no elevators were installed, which caused great trouble to the lives and work of the residents upstairs. As the aging population becomes more and more serious, the interference with the lives and work of the residents has become more serious. With the advancement of the old house renovation project, adding elevators to old buildings has become a more important task and one of the important manifestations of improving residents' living conditions.

[0003] Modular retrofit elevators are currently more commonly installed because they are split into multiple modules and prefabricated in the factory. The modules are easy to lift, transport and install as a whole. Elevator modules mostly use steel structures and are assembled to form an elevator shaft. The lower part of the elevator shaft is fixed to the cast ground. The elevator modules are fixed to the building wall structure through connectors, so that the elevator shaft is overlapped and fixed to the outside of the building wall.

[0004] In the prior art, the construction method of external embedded reinforcement and embedded plates is mostly used between the elevator module of the added elevator and the building wall structure. During construction, it is necessary to embed reinforcement on the outside of the building wall structure. This connection form is complicated and slow to construct, and it is necessary to set up a construction platform first and then dismantle it after construction, resulting in a long construction time and a poor construction environment, which has a great impact on the lives of residents during construction.

The capping module is fixedly connected to the upper standard elevator module 2 by pouring high-strength grouting material through the column connector 6, and the installation of the elevator is completed.
