Transformation construction method for existing large space structure

Abstract

The invention relates to a transformation construction method for an existing large space structure, belongs to the technical field of building construction, and is used for solving the problem of erection of an all-round scaffold for renovation transformation construction of the inner surface of an existing large-clear-height and large-span building space. According to the construction method, a first section of sliding rail is installed through a temporary scaffold, the sliding rail is connected with a top beam plate structure of the existing large space structure, then an automatic walking system is installed, then a lifting system, a sensor and camera equipment are installed on the automatic walking system, then splicing and hoisting of a whole suspension type steel platform system are completed, then the construction operation platform is hoisted through the lifting system, a vertical logistics system is installed, then the automatic walking system is operated to move to a designated position along the track, temporary separation is carried out on a construction area and an area which is not temporarily constructed; rolling construction is repeated, and finally renovation and transformation construction of all construction areas is completed.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a construction method for reconstructing an existing large space structure. Background technique [0002] At present, the reconstruction and construction of large-span and large-space structures often adopt the method of building a full house of scaffolding. This traditional method of relying on a full house of scaffolding has disadvantages such as labor-intensive, time-consuming, cost-intensive, and increased construction risks. For large-scale buildings such as large-scale stadiums and exhibition centers, it is often necessary to stop opening to the outside world during the renovation and construction process, and the social and economic benefits are generally low. How to solve or optimize the construction method of large space building structure renovation, improve construction efficiency, respond to the call of national greening and industrialization, and achiev...
