Abstract

The invention discloses an overall lifting method of a corridor under an unfavorable space condition, which comprises the steps of firstly dividing the corridor into a plurality of sections according to an overall design structure of the corridor, secondly assembling the corridor from two ends to the middle in sequence, assembling the corridor to an unfavorable space position, at least two sections of the corridor to be assembled, then lifting the corridor close to the unfavorable space position by adopting the overall lifting method of the corridor under the unfavorable space condition, and finally lifting a main body of the corridor of the rest sections. The narrow and small space in scene of this scheme make full use of solves the vestibule and assembles, hoist and mount, lower suspension pole installation etc. to guarantee going on smoothly of vestibule hoist and mount, the project that effectual reduction project should place environmental problem lead to the time limit for a project, personnel can not the rational utilization problem, reduce the high altitude simultaneously and assemble the safe risk that brings. The integral sectional hoisting mode has the advantages of higher operation efficiency, more reasonable space application and time application, high installation speed, shortened construction period, convenient installation of workers and safer construction process.

Description

Corridor hoisting and integral hoisting method under condition of no interest space Technical Field The invention relates to the technical field of construction of building galleries, in particular to a gallery hoisting and integral hoisting method under the condition of no space. Background In the building construction field of the corridor, the conventional steel structure assembling method comprises the steps of carrying out assembling after carrying out bulk or sheet-shaped transportation on site on the steel structure, and then lifting in place or jacking the steel structure corridor to a corresponding bracket in an integral jacking mode, so that the circulating operation can be carried out until the hoisting process is completed, and the next working procedure can be carried out. Conventional steel structure assembly requires a wider and relatively flat assembly field to ensure that the on-site hoisting equipment is convenient for in-place hoisting. However, the field conditions, logistics and sites are often limited, the construction cannot be performed by adopting the process, and the extremely tight project period is difficult to ensure. Particularly, under the environment that barriers and buildings are arranged around and the construction width is narrow, the assembly and the hoisting of the corridor are the problems to be solved in the field. Disclosure of Invention Due to the defects in the prior art, the invention provides a corridor hoisting and integral hoisting method under the condition of no space utilization, so as to solve the problem of high corridor hoisting difficulty under the condition of no space utilization in the prior art. In order to achieve the above purpose, the present invention provides the following technical solutions: the corridor hoisting method under the condition of no interest space comprises the following steps: Step 1, calculating the size of units assembled by the corridor according to the field space conditions; step 2, a piece of hoisting equipment is arranged at the far end of the corridor installation section in advance; step 3, sectional assembling the main body of the corridor on the adjacent open ground; step 4, lifting and shifting the whole corridor main body to a certain height below the target position from the ground, suspending the corridor main body, and lifting the far end of the corridor main body by using preset lifting equipment; Step 5, installing a lower suspension rod; Step 6, after the installation of the lower suspension rod is completed, the far end of the corridor main body is lifted, and the near end is landed; Step 7, installing a mounting bracket at the proximal end of the corridor main body; step 8, hoisting the proximal end of the corridor main body by using another hoisting device, and hoisting the hoisting devices at the two ends at the same time until the corridor main body reaches the installation position; And 9, adjusting the corridor main body to a specified position and then fixing.
