Precast Slab with Integrated Reservation Boxes for Floor Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The construction process of building floors is lengthy and tedious due to the need for multiple trades to identify and install reservation spaces and duct networks, which complicates the assembly of pre-slabs and compression slabs.
Innovation Solution
A pre-slab with integrated reservations and guide means, such as reservation boxes and incorporations, that are secured to the slab and include alphanumeric signs for identification, allowing for direct installation of duct networks and simplifying the assembly process by eliminating the need for additional reservation spaces and trades.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple trades intervene to install reservation spaces and duct networks after pre-slab assembly, then the floor can be constructed with proper reservations, but the construction process becomes lengthy and tedious
Solution Approach 1:
The patent applies preliminary action by pre-installing incorporations (formwork elements) onto pre-slabs at the factory before delivery to the construction site. These incorporations are positioned in advance to create reservations in the compression slab, eliminating the need for multiple trades to intervene later and significantly reducing construction time while ensuring proper installation.
Solution Approach 2:
The patent merges the pre-slab assembly function with the reservation creation function by integrating incorporations onto the pre-slabs. This combination allows a single trade to handle both pre-slab installation and reservation preparation, eliminating the need for separate interventions by electricians and plumbers, thereby reducing both time and complexity.
2Reliability
If multiple trades are required to identify and install reservation spaces, then proper reservations can be created, but the assembly process becomes more complex
Solution Approach 1:
The patent applies self-service by designing pre-slabs with pre-positioned incorporations that automatically provide the reservation spaces needed by electricians and plumbers. The incorporations are factory-prepared with accurate positioning, allowing the installation team to simply follow the planned layout without requiring multiple trades to intervene and create reservations manually, thus reducing assembly complexity while maintaining accuracy.
3Reliability
If incorporations are installed after pre-slab assembly, then reservations can be created, but the same trade must perform multiple separate operations
Solution Approach 1:
The patent applies preliminary action by having incorporations pre-installed on pre-slabs at the factory. This allows the same trade to simply position and secure the pre-slabs with incorporations during assembly, rather than stopping to install incorporations after assembly, thereby maintaining reservation creation reliability while significantly improving assembly speed and productivity.

AI summary
The invention relates to a precast slab (1) comprising a concrete body (2). According to the invention, the precast slab includes an insert (6, 7) which is attached to the precast slab so as to project from an upper face of the precast slab without extending to an underside of the precast slab, the insert being intended to form a recess in a compression slab subsequently poured onto the precast slab. The invention also relates to a method for manufacturing a floor using such a precast slab.
