Extra-large area concrete floor structure shrinkage control construction technology

Abstract

The invention relates to an extra-large area concrete floor structure shrinkage control construction technology which effectively controls the extra-large area concrete cracks. When the shrinkage control construction technology is applied, control is mainly performed in the aspects of design and construction technology and comprises design control, material control, construction control and on-site monitoring control. According to the extra-large area concrete floor structure shrinkage control construction technology, the integrality of the floor structure can be effectively ensured, the concrete floor structure durability is improved, construction is reasonably organized, the construction period can be greatly shortened compared with standard arrangement post-cast strip scheme, and the giant economic benefits are brought to engineering projects, particularly industrial projects.

Description

technical field [0001] The invention relates to a concrete construction technology, in particular, the invention relates to a construction technology for shrinkage control of a super-large-area concrete ground structure applied in the field of building construction. Background technique [0002] With the development of the national economy and the improvement of living standards, people tend to diversify and complicate the functions of buildings. While high-rise and ultra-high-rise buildings continue to increase, buildings with super-long and super-wide plane dimensions are also emerging rapidly, such as large public buildings, industrial plants and commercial centers. In view of the structural integrity, use function and construction period requirements of the above-mentioned large-scale buildings, most of the ground or floors of such buildings are required to have no expansion joints and post-pouring belts, or the distance between expansion joints exceeds the requirements ...

AI Technical Summary

Problems solved by technology

Therefore, there are not many theoretical studies on crack control of such structures, and it is difficult to find specific design and construction methods for such structures in codes, regulations, and even various construction manuals in our country.

Engineering and technical personnel lack quantitative analysis and calculation of such structures, but can only design and construct qualitatively based on engineering experience. The blindness and unscientific nature of this design and construction have caused a lot of waste and unsafe hidden dangers in the project

In view of the fact that the shrinkage control construction of super-large-area concrete structures has become more and more widely used in recent years, the engineering theory research in this area is not comprehensive, systematic and standardized, and there is still a lack of a simple and effective design and construction method.
