Jacking process and jacking mechanism for additionally installing elevator in existing house

Abstract

The invention discloses a jacking process and a jacking mechanism for additionally installing an elevator in an existing house, and the jacking process and the jacking mechanism are used for additionally installing an elevator in an old community. The main process and mechanism comprise the steps that an elevator foundation pit is constructed, and steel column embedded parts and hoisting equipment embedded parts are pre-embedded; a scissor crane is mounted; an elevator shaft steel structure is spliced, and an enclosure curtain wall, a roof hook beam and a roof panel are mounted; a scissor crane jacking platform beam is connected with the elevator shaft steel structure beam; a jacking guide rail and a guide rail pulley connected with the jacking platform beam are installed; the first section of elevator shaft is jacked to a preset position; a steel column of the next section of the steel structure hoistway continues to be spliced; and the mounting processes are repeated to finish the entire elevator mounting. The jacking process has the advantages that the steel structure, the enclosure structure and the electromechanical equipment of each section of elevator can be installed on the ground, and then the elevator is jacked in place at a time. The jacking process is high in adaptability, fast in construction progress, simple in structure and convenient to operate, and high-altitude hoisting and mounting operation is reduced.

Description

technical field [0001] The invention belongs to the technical field of steel structure addition elevator construction in construction engineering, and in particular relates to a layer-by-layer floor-by-floor jacking construction process for adding elevators to existing residential buildings and a corresponding matching jacking mechanism. Background technique [0002] In order to adapt to social and economic development and improve people's living standards, the country has promulgated relevant policies and regulations on adding elevators to old houses. The roads around the old residence are narrow and the management is chaotic, which makes many construction changes due to the addition of elevators. There are two main methods for the existing elevator addition construction. One is the traditional layer-by-layer construction. This method has a slow construction progress and a long cycle, and it is dangerous for workers to work at heights, which is likely to cause inconvenience...
