A Construction Method for Installing Elevators in Existing Multi-storey Residences

Abstract

The invention discloses a construction method for additionally arranging of elevators to an existing multi-storey residence. The construction method comprises the steps of construction preparation, excavation of an elevator foundation pit and installation of a base of an elevator shaft, construction of the top of the elevator shaft, installation, connection and fixation of the elevator shaft, installation and trial operation of the elevator and periodic maintenance and repair. The elevator foundation pit is arranged on an original foundation of the existing multi-storey residence, and the baseof the elevator shaft is fixed on the original foundation of the existing multi-storey residence. The installation, connection and fixation of the elevator shaft comprise the installation and fixation between elevator shaft main supporting columns and the installation and fixation between the elevator shaft and the existing multi-storey residence. According to the arrangement, reasonable workingprocedures are conducive to the smooth construction and follow-up stable operation of the elevator, and at the same time, the connection relationship and structure of the base and supporting columns of the elevator shaft are further opened, so that the connection between the elevator and the existing multi-storey residence is firmly and stably, the operation of the elevator is guaranteed to a certain extent; and the structure and method for reinforcement can be widely applied to the additionally arranging of elevators in various buildings.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a construction method for adding an elevator to an existing multi-storey residence. Background technique [0002] According to the regulations in the "Code for Residential Design" GB-50096-1999 (2003 Edition), elevators must be installed for residential buildings with more than seven floors or residential floors whose height exceeds 16m according to the outdoor design ground. Simultaneously, explain that the dwelling house below seven storeys can not install elevator, in order to save cost, most of dwelling house below seven storeys is not all designed and installed with elevator. [0003] However, with the development of the economy and the aging of the population in our country, many existing old houses with less than seven floors have not installed elevators, which has brought more inconvenience to the travel of many elderly people. [0004] The Chinese patent document wi...

Problems solved by technology

[0005] In the above scheme, the additional elevator is attached to the outer surface of the existing building, and a new elevator door opening is opened at the corresponding position on the ground floor. For old buildings, the stress stability itself needs to be improved, so the scope of application of the above scheme will be greatly limited, and there may even be certain safety hazards, and further improvement is needed
