Description

Modular assembled elevator with auxiliary anti-vibration/vibration-absorbing unit-balcony integrated integrated system

technical field

The invention belongs to the technical field of original building repairs, and relates to a modular assembly elevator-balcony integrated system with auxiliary anti-shock/shock-absorbing units installed on the outside of an old residential area.

Background technique

A large number of low and multi-story brick-concrete residential structures built in the last century in my country did not install elevators. At present, as my country's population aging process is accelerating and the economically developed eastern coastal areas have entered the aging society ahead of schedule, the lack of elevators in old communities has become a huge inconvenience that seriously affects the lives of the elderly. It has brought great inconvenience, and related problems have seriously affected the happiness index of the elderly and even the whole society, and become a major issue affecting the quality of life of the elderly and families with babies.

At present, there are very few successful cases of installing elevators in old residential quarters. On the one hand, at this stage, the installation of elevators in the old community does not consider the use of modular buildings as the basic elements, and does not adopt the construction method of prefabrication and assembly, which leads to a large amount of on-site engineering, complex construction plans, and long construction time. At present, the retrofit scheme of adding elevators without modular buildings as the basic elements requires a large number of additional scaffoldings to be built around the old residential areas for the installation of tall elevator shaft frames; as it is difficult to find the positioning axis of the original structure, the site is an elevator shaft frame The difficulty of accurate measurement, positioning and setting out has also been greatly improved. Because of this, the current renovation project of adding elevators to the old community is not only complicated in construction, but also has a long on-site construction period, which brings great inconvenience to the lives of residents in the community. On the other hand, do not fully consider utilizing the added elevator structure to further improve other functions of the original structure while considering adding an elevator at present. First of all, due to the early construction of brick-concrete structures in the old community, the seismic capacity is generally lower than the fortification intensity of the area; secondly, while installing elevators, it is also possible to consider adding balconies to the old residential buildings. Improve the living quality of residents while increasing the construction difficulty of elevators.

In order to overcome the above-mentioned problems, the present invention proposes a modular assembly elevator-balcony integrated system that uses modular balconies as the basic elements, greatly simplifies the construction difficulty of adding elevators, and shortens the construction period of adding elevators to two to three days , to achieve the goal of shortening the elevator construction period, reducing the difficulty of renovation, and improving the traffic conditions of residents; at the same time, by setting high-performance connecting elements between the modular balcony and the original structure to connect the two reliably, it can significantly improve the earthquake resistance of old residential buildings. disaster resilience.
