Precast Column Array Construction for High-Tech Plant Speed
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional construction methods are inefficient and complex, particularly for high-tech plants, as they require complicated route arrangements for hoisting structures, shipping materials, and labor, which hinder rapid construction and fail to meet the fast-paced demands of high-tech industries.
Innovation Solution
A method involving the use of precast columns, pre-fabricated beam rebar assemblies, and precast slab panels, where these components are strategically positioned and jointed to form beam rebar cages, with concrete poured between them, allowing for efficient and rapid construction by repeating this process story by story, optimizing the use of space and simplifying the construction workflow.

Engineering Contradiction Analysis
1Productivity
If conventional construction method is used to construct building story by story on the whole predetermined construction area, then the construction can be completed following traditional procedures, but the routes for construction work such as hoisting structure, shipping construction materials, or labor passageways become definitely complicated and construction speed decreases
Solution Approach 1:
The construction site is divided into multiple construction areas, with each area containing a plurality of columns. The construction process is segmented into discrete steps: first constructing columns in each area, then connecting them with beams, and finally adding floor slabs. This segmentation allows parallel construction in multiple areas simultaneously, simplifying route arrangements and improving construction speed.
Solution Approach 2:
Columns are pre-positioned in each construction area before beam installation. The column bases are prepared in advance with reinforcement bars extending upward, ready to receive beam connections. This preliminary action eliminates the need for complex on-site column positioning and foundation preparation during the main construction phase, simplifying construction routes and accelerating the process.
2Productivity
If conventional construction method is used for high-tech plants, then traditional construction procedures are followed, but the construction cannot meet the fast-paced demands and production timelines of high-tech industries
Solution Approach 1:
The building is divided into multiple construction areas with columns arranged in grids. Each area can be constructed independently and simultaneously, allowing parallel workflow. The construction process is further segmented into column installation, beam connection, and slab placement phases, enabling optimized scheduling and reduced overall construction time for high-tech facilities.
Solution Approach 2:
Column bases are prepared in advance with reinforcement bars extending upward, ready to receive beam connections. This preliminary preparation eliminates time-consuming on-site foundation work and column positioning during the main construction phase, significantly reducing construction time and enabling faster delivery of high-tech plants.
3Productivity
If more columns are constructed in parallel to reduce construction time, then construction speed increases, but the arrangement of construction routes and labor passageways becomes more complicated
Solution Approach 1:
The site is divided into multiple independent construction areas, each containing a manageable number of columns. This segmentation allows parallel construction without overwhelming route complexity, as each area can be serviced by dedicated equipment and labor teams. The modular nature of construction areas enables scalable expansion while maintaining manageable logistics in each zone.

AI summary
A construction method for a building is provided that includes the steps of: hoisting and positioning a plurality of precast columns on at least a portion of a predetermined area of a construction site to form a precast column array having at least two spans along a first direction and one or more spans along a second direction substantially perpendicular to the first direction; positioning the pre-fabricated beam rebar assemblies between adjacent precast columns, positioning each of the precast slab panels on support potions on the precast columns, assembling the beam cage and pouring the concrete into the molds for the beam cage to accomplish the structure of a single story; and repeating the steps of constructing the above-mentioned precast column array until completion of the structure of all stories of the building.
