The invention discloses an overall assembly jacking construction method for a grid floor support plate structure in a limited space. The high-altitude grid floor support plate structure is constructed in the limited space, a grid and a structure on the grid are integrally assembled and formed to form a pre-assembly area by utilizing an existing ground space, the pre-assembly area is integrally jacked to a predetermined elevation, and during jacking, due to the fact that a safe space is formed between the pre-assembly area and a main body structure, the whole construction is safe and efficient; and finally, after edge sealing and installation, an installation area forms the grid floor support plate structure, the purpose of overall assembly jacking is achieved, construction is easy and convenient, the danger of high-altitude operation is reduced, and the difficulty of vertical and horizontal transportation is solved, especially in the horizontal and vertical directions. According to the overall assembly jacking construction method for the grid floor support plate structure in the limited space, the problems that an existing large-span grid structure installation construction method in the limited space is large in potential safety hazard and low in construction efficiency are solved.
Description
technical field [0001] The invention relates to the technical field of building construction, in particular to an overall assembly jacking construction method for a grid floor bearing plate structure in a confined space. Background technique [0002] In the field of modern construction, with the development of cities and the needs of human beings in space, there are more and more large-span structures, especially the grid structure is widely used in large-span structures. The installation of the grid frame needs to be adapted to the working conditions under different conditions, especially in the confined space, and when working at heights, the installation quality cannot be guaranteed, the safety hazard is large, the construction efficiency is more serious, and the vertical and horizontal transportation is difficult. Contents of the invention [0003] In order to overcome the defects existing in the prior art, a construction method for the overall assembly and lifting of ...
