Prefabricated Storey Modules Vertical Hoisting Method
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current building construction methods involving frame structures are labor-intensive and time-consuming, particularly due to sequential stages requiring waiting for concrete to set and separate installation of utilities, leading to high labor costs and inefficiencies.
Innovation Solution
A method where prefabricated storey modules, including slabs, beams, ceilings, and utilities, are hoisted vertically using cranes and pull cables, and attached to columns via articulated brackets, allowing simultaneous installation of multiple components and reducing on-site construction time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sequential construction stages are used with concrete slabs, then structural strength is ensured, but construction time and labor costs increase significantly
Solution Approach 1:
The building is divided into modular storey modules that can be prefabricated separately and assembled systematically. Each module contains complete functional elements (slabs, beams, ceilings, utilities) that are pre-assembled in controlled environments, enabling parallel production and reducing on-site construction time while maintaining structural integrity through standardized connection details
Solution Approach 2:
Storey modules are prefabricated in advance with all necessary components (slabs, beams, ceilings, utilities) assembled before site delivery. This preliminary preparation allows concurrent manufacturing of multiple modules while site preparation occurs, eliminating sequential waiting periods and accelerating overall construction pace without compromising structural strength
2Adaptability or versatility
If utilities are installed separately after slab construction, then installation flexibility is maintained, but labor costs and construction time increase
Solution Approach 1:
Utilities (electrical conduits, plumbing pipes, HVAC ducts) are integrated into the storey modules during prefabrication, combining structural and service functions into unified assemblies. This merging allows utilities to be installed concurrently with module manufacturing rather than sequentially afterward, reducing total construction time while maintaining flexibility through modular design that accommodates various utility configurations
3Manufacturing precision
If heavy cranes are used to hoist slabs in situ, then placement precision is achieved, but equipment cost and site complexity increase
Solution Approach 1:
The building structure is segmented into manageable storey modules of standardized dimensions that can be hoisted by smaller, more economical cranes. This segmentation reduces the lifting weight and size requirements for cranes compared to hoisting complete floor slabs, simplifying equipment needs while maintaining placement precision through modular handling and standardized connection points
Solution Approach 2:
The construction approach transitions from horizontal slab placement to vertical module stacking. Storey modules are hoisted vertically and stacked upon previously installed modules, changing the construction dimension from horizontal to vertical. This dimensional shift enables the use of smaller cranes that can operate in limited site spaces while achieving precise placement through controlled vertical positioning and standardized interface connections

AI summary
The invention relates to a method for constructing buildings having a reticular structure and to a building constructed using said method. The method comprises the steps of: erecting a set of columns (1, 2, 3, 4) that form the vertical supporting structure, on foundations or piles; arranging, in a lower zone of the structure (100), a heap (5) with fully constructed floor modules (6) inside the space defined by the columns (1, 2, 3, 4) and in the same vertical order as the definitive order planned for each of the floor modules of the structure (100) forming the building; raising the floor modules (6) by means of elevators, to place same in their definitive positions at corresponding heights; and joining the floor modules (6) to the columns (1, 2, 3, 4) by means of screwing, welding, riveting or an equivalent system.
