Problems solved by technology

[0003] At present, in the installation of elevators, it is common to carry out pit foundation construction on the outdoor ground at a certain distance from the existing multi-storey residences, and then gradually install the elevator shaft upwards, and then add a corridor between the elevator shaft and the existing multi-storey residences Connection, but there are many old residential buildings with limited outdoor ground conditions and no pit foundation construction, so it is difficult to install elevators

Abstract

The invention provides a prefabricated steel-structure bottom pit foundation for addition of an elevator for an existing multi-storey building and a construction method, and relates to an elevator bottom pit foundation and a construction method. A foundation platform is arranged on the top of a foundation tubular pile, a steel-structured bottom pit frame is fixed on the upper surface of the foundation platform, and comprises a cross-shaped reinforcing beam, four steel tube stand columns, four bottom pit upper cross beams and four bottom pit lower cross beams which are integrated; the four steel tube stand columns are rectangular; the upper ends of each two adjacent steel tube stand columns are connected and fixed through a bottom pit upper cross beam; the middles of each two adjacent steeltube stand columns are connected and fixed through a bottom pit lower cross beam; the cross-shaped reinforcing beam is horizontally fixed between the four bottom pit lower cross beams; a bottom plateis arranged between the cross-shaped reinforcing beam and the four bottom pit lower cross beams; and a buffer base is fixedly mounted in the center of the upper surface of the cross-shaped reinforcing beam. The prefabricated steel-structure bottom pit foundation for addition of the elevator for the existing multi-storey building is novel in structure and convenient to construct, the steel-structured bottom pit frame is arranged at the gate of a unit door of the multi-storey building, and the cost is saved.

Description

technical field [0001] The invention relates to an elevator pit foundation and a construction method, in particular to a prefabricated assembled steel structure pit foundation and a construction method for existing multi-storey residential buildings. Background technique [0002] Most of the existing multi-storey residences are limited by economic development and technical level and do not have elevators. However, with the acceleration of population aging and the improvement of people's living standards in recent years, residences without elevators have been difficult to adapt to the people's demand for barrier-free access. The pursuit of living quality and comfort, and the government has also begun to vigorously promote livelihood projects, encouraging the installation of elevators for conditional old residences. Therefore, the demand for installing elevators in existing multi-storey residences is also increasing. [0003] At present, in the elevator installation project, ...
