Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The traditional building process is time-consuming and labor-intensive, particularly in wall and floor construction, leading to high construction costs and prolonged building times, with existing modular floor slabs lacking sufficient structural strength for large-span integral floor slabs.
Innovation Solution
A modular building structure featuring prefabricated floor slab frames, wall panels, and ceiling modules with interconnected designs, including U-shaped clips and press-fit connections, that allow for rapid assembly and integration of utilities like electrical wiring and plumbing, optimizing the installation of connections between floor slabs, walls, and beams.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If cast-in-place concrete structures are used for floor assembly, then structural strength is achieved, but construction time and labor intensity increase significantly
Solution Approach 1:
The floor structure is divided into modular components: precast concrete floor slabs, wall panels with embedded steel bars, and standardized connection details. This segmentation allows parallel production of components in different locations, reducing overall construction time while maintaining structural integrity through pre-designed connection mechanisms.
Solution Approach 2:
Steel reinforcement bars and connection elements are pre-installed in floor slabs and wall panels during manufacturing. This preliminary action eliminates the need for time-consuming on-site steel bar laying and concrete pouring, as components arrive ready for assembly with all reinforcement work completed in the controlled factory environment.
2Stability of the object's composition
If traditional wall building methods are used, then wall structure is achieved, but construction time and expenses increase
Solution Approach 1:
Walls are constructed from standardized precast panels containing embedded steel reinforcement and pre-installed utility conduits. These modular panels can be manufactured simultaneously in factories while site preparation occurs, then rapidly assembled on-site, dramatically improving productivity compared to traditional sequential wall construction methods.
Solution Approach 2:
Multiple functions are integrated into single wall panels: structural support, thermal insulation, electrical conduit routing, and plumbing pathways are all incorporated into the same prefabricated component. This merging reduces the number of separate construction steps and materials needed, accelerating the building process.
3Ease of operation
If modular floor slabs are used with splicing, then assembly is simplified, but structural strength for large-span integral floor slabs is insufficient
Solution Approach 1:
Steel reinforcement bars are embedded within the concrete floor slabs and wall panels during manufacturing. This nesting of reinforcement within the structural element creates a composite system where the steel and concrete work together as an integrated unit, providing the tensile strength of steel with the compressive strength and fire resistance of concrete, thereby achieving high structural strength while maintaining modular assembly simplicity.

AI summary
The present invention provides a modular building structure, comprising: a plurality of floor slab frames, a plurality of first wall panels, a plurality of second wall panels, a plurality of floor module boards, and a plurality of ceiling module boards. The two adjacent floor slab frames are connected through a plurality of clips, so as to fix the floor slab frames together. Through those structure, the workers can quickly build multiple floors with strength not much different from normal floors, while all the modular components ensure that they can be prefabricated in advance in the factory, which can also significantly improve the transportation efficiency.
