External elevator assembled prefabricated fundamental component of existing building and construction method thereof

Abstract

The invention relates to an external elevator assembled prefabricated fundamental component of an existing building and a construction method thereof, and belongs to the technical field of existing building comprehensive improving. The external elevator assembled prefabricated fundamental component comprises external elevator prefabricated fundamental components and external elevator steel columnbottoms. Each elevator prefabricated fundamental component is formed by integrally pouring a raft foundation, concrete shear walls, steel columns, studs and embedded bolts, and the integrally-poured prefabricated fundamental component is installed on a pad layer at a ladder which is prepared in advance after being hoisted. The external elevator assembled prefabricated fundamental component of theexisting building and the construction method thereof have the obvious advantages that the construction period is short, the construction speed is increased, thus the building cost is lowered, duringconstruction, the daily life of an original resident is not influenced, and an elevator is freely and flexibly installed. Steel structures are adopted by the upper portion of the structure and are conveniently connected with the prefabricated fundamental components, the dead load is small, and the foundation is simple. As the existing building is improved and the people-centered idea is graduallyimplemented, it can be foreseen that on the premise of satisfying the construction quality, if the technology is applied and popularized, the existing building is additionally provided with an elevator and is matched with the reliable prefabricated foundation components, which has obvious economic benefit and practical significance.

Description

technical field [0001] The invention relates to an assembled prefabricated basic component with an elevator added to an existing building and a construction method thereof, in particular to a basic structure transformation and a construction method for adding a vertical passage to an existing building, and belongs to the technical field of comprehensive transformation of existing buildings. Background technique [0002] Many existing buildings in my country were built in the 1980s and 1990s. At that time, due to the constraints of economic conditions and other factors, the building functions were simple and the quality of life was poor. The existing buildings with seven floors and below were not equipped with elevators. With the gradual improvement of urban living standards and the continuous improvement of economic conditions, people's requirements for quality of life are also getting higher and higher. At present, the owners of these existing buildings, especially the owne...

Problems solved by technology

The main purpose is to solve the problem that the existing building did not have an elevator due to economic and technical constraints. Now it is necessary to add an additional elevator to improve the travel of residents. The use of prefabricated basic components of the existing building plus an elevator can shorten the construction period and reduce the construction cost.
