Concrete Floor Slab Molding With Stable Angle-Profile Anchoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for producing concrete floor slabs with metallic angle profiles are inefficient and unsatisfactory in terms of anchoring the angle profiles in the concrete, leading to potential displacement or tilting during the pouring process.
Innovation Solution
The method involves inserting the metallic angle profile into the production mold with the first leg resting on the floor surface and the second leg aligned with the side part, securing it during concrete pouring, and removing the slab with the lower surface first, ensuring the angle profile is anchored at the lower end of the side surfaces. This can be achieved through mechanical, vacuum, or electromagnetic means, and the mold design allows for movable longitudinal sections to facilitate demolding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the angle profile is inserted into the production mold before pouring concrete, then the anchoring position is predetermined, but the angle profile may be displaced or tilted during concrete pouring
Solution Approach 1:
The angle profile is inserted and positioned in advance before concrete pouring, with the first leg resting on the floor surface and the second leg aligned with the side part. This preliminary positioning ensures the angle profile is correctly placed before the concrete is poured, preventing displacement during the pouring process.
Solution Approach 2:
A holding device is introduced as an intermediary element to secure the angle profile during concrete pouring. The holding device prevents displacement and tilting of the angle profile by providing additional support and fixation while the concrete is being poured, ensuring both positioning precision and stability.
2Strength
If the angle profile is securely anchored in the concrete, then the structural integrity is improved, but the production process becomes more complex
Solution Approach 1:
The angle profile integration is merged with the concrete pouring process itself. The angle profile is positioned in the mold before pouring, and the concrete is poured around it in a single continuous operation, eliminating the need for separate anchoring steps and reducing overall process complexity while maintaining structural integrity.
Solution Approach 2:
The concrete pouring process itself serves to anchor the angle profile. As the concrete is poured and surrounds the angle profile, it automatically provides the anchoring function through adhesion and mechanical interlocking, eliminating the need for additional anchoring devices or complex fixation mechanisms.
3Ease of manufacture
If the concrete is poured with the angle profile in place, then the angle opening allows favorable inflow, but the angle profile may move during pouring
Solution Approach 1:
The angle profile is preliminarily positioned and secured in the mold before concrete pouring begins. This ensures the angle opening is correctly oriented to allow favorable concrete inflow while the profile remains stable throughout the pouring process due to the preliminary positioning and holding device support.
Solution Approach 2:
The holding device acts as an intermediary that maintains the angle profile's position during concrete pouring. It allows the concrete to flow freely through the angle opening while simultaneously preventing any displacement or tilting of the angle profile, reconciling the conflicting requirements of ease of manufacture and position stability.
