Additional elevator foundation structure of old building and construction method of additional elevator foundation structure

Abstract

The invention relates to an additional elevator foundation structure of an old building and a construction method of the additional elevator foundation structure, and belongs to the technical field of seismic hardening. The additional elevator foundation structure comprises an external elevator upper structure and an additional elevator foundation structure, wherein the external elevator foundation structure comprises a new pile foundation, a new pile foundation bearing platform, a new bearing platform cushion layer, a new retaining wall and a waterproof protecting layer arranged between the new pile foundation bearing platform and the new bearing platform cushion layer; the upper structure is a steel structure and is connected with the foundation conveniently; the dead load is low; the foundation is simple; the site operation period is short; influences on the foundation of the original structure are low; the position of the original underground pipeline is not required to be changed; the daily life of the original residents is not affected during construction of the additional elevator foundation structure; and an elevator is mounted freely and flexibly. The new elevator is used safely and reliably; the residents go upstairs and downstairs conveniently; the problem that old people and handicapped persons go out inconveniently is solved; in modification of an old housing estate, a mode of bearing an additional elevator by using the additional elevator foundation structure can be widely used in modification of a building which needs the external elevator for improving life convenience; and the additional elevator foundation structure has a wide application prospect.

Description

Technical field [0001] The invention relates to an old house reconstruction structure and a construction method thereof, in particular to a basic structure reconstruction and a construction method of an old house adding a vertical passage, and belongs to the technical field of seismic reinforcement. Background technique [0002] With the gradual improvement of urban living standards and the continuous improvement of economic conditions, people's requirements for the quality of life are getting higher and higher. Many old residential communities in my country were built in the 1980s and 1990s. At that time, due to economic conditions and other factors, the building functions were simple and the quality of life was poor. There were no elevators installed in houses of six floors and below. At present, most of the owners of these old houses are the elderly and the disabled. Such people are inconvenient to go up and down the stairs, which restricts their travel and outdoor activities....
