Concrete Pre-slab with Spoiler Retaining Elements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for constructing floors using precast concrete slabs are time-consuming due to the need for extensive formwork setup, particularly at the peripheral edges, which requires additional wooden or other elements.
Innovation Solution
Incorporating fixing bases on the pre-slabs for securing spoiler-type retaining elements that form the peripheral rim of the formwork, allowing for quicker setup and potentially including thermal insulation features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional formwork setup is used with wooden or other elements at peripheral edges, then the formwork can be completed, but the construction time increases significantly
Solution Approach 1:
The fixing bases are integrated into the pre-slab structure during manufacturing, so that when the pre-slab is installed on site, the fixing bases are already in position and ready to receive the retaining elements. This preliminary preparation eliminates the need for operators to manually set up formwork edges, significantly reducing construction time while maintaining formwork completeness.
2Ease of manufacture
If retaining elements are added to form the peripheral rim, then the formwork is complete, but additional materials and assembly steps are required
Solution Approach 1:
The retaining elements are designed to be secured directly to the fixing bases that are already integrated into the pre-slab. This merging of the retaining element assembly with the pre-slab installation process eliminates the need for separate formwork assembly steps and reduces the quantity of additional materials required, as the fixing bases serve dual purposes: structural integration and formwork support.

AI summary
The plate (1) has a fixing base (4) anchored in a board of a concrete body (2), where the fixing base receives a retaining element (9). The retaining element is rigidly connected to the fixing base by a fitting part that is protruded from an upper face of the concrete body to constitute a portion of a formwork of a compressed concrete slab. The retaining element comprises a shape of a spoiler, where the retaining element forms a thermal insulator that is attached with the fixing base.
