Converse construction process for middle-high steel structure building

Abstract

The invention relates to a converse construction process for the middle-high steel structure building, belonging to the steel structure system construction field and aiming at solving the problems that the construction surfaces are less, the construction efficiency is low, the construction period is long and the manufacturing of the steel structure components can not meet the integral mounting quality standard requirements because the steel floorslabs and the steel structure frameworks are constructed synchronously during the construction of the prior steel structure building. The converse construction process for the middle-high steel structure building comprises the following steps: refining and enlarging the connection nodes of the steel structure frameworks; processing and assembling the steel structure components according to the enlarged construction drawing; transporting and stacking the steel structure components; mounting the steel structure frameworks; and moungin the steel floorslabs. Because the converse construction process of mouting the main structures of all the steel structure frameworks before the mouting the steel floorslabs is adopted, the steel structure frameworks and the steel floorslabs can be constructed on the same plane and can be constructed in a vertical and cross way without mutual influence, the construction speed can be accelerated, and the construction efficiency can be improved. The converse construction process is simple, convenient, economical, reasonable, safe and reliable, ensures high mounting precision and can be applied to the construction of various middle-high steel structure buildings.

Description

technical field [0001] The invention relates to the construction field of a steel structure building system, in particular to a reverse construction process of a medium-high-rise steel structure building. Background technique [0002] At present, most medium and high-rise buildings are mainly traditional concrete structures. Although concrete structures have relatively mature design and construction experience, they are heavy in weight, relatively high in basic investment, slow in construction speed, and long in cycle. In recent years, with the development of social economy and productivity, steel structure buildings have developed rapidly due to their advantages of small footprint, low comprehensive cost, fast construction speed, easy quality assurance, and environmental protection, and are widely used in factories, middle and high-rise or on large buildings. The construction process of the existing steel structure building is as follows: first install the steel columns on...
