Integrated Localization Steel Frame for Lightweight Building Construction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The construction of lightweight steel buildings is hindered by complex and costly procedures for embedding anchor bolts into concrete ring beams, requiring precise positioning of steel columns and bracing members, which is time-consuming and inefficient.
Innovation Solution
An integrated localization steel frame using cold formed thin-walled profile steels, steel angles, or steel channels with connectors and anchor bolts, allowing for accurate linear localization and easy adjustment, replacing the need for rebar cages in concrete ring beams, and simplifying the assembly process by pre-determining connector positions and casting concrete ring beams on a leveled foundation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If individual steel columns and bracing members are assembled on site with embedded anchor bolts, then the steel frame structure can be constructed, but the work procedures become complicated and construction cost increases
Solution Approach 1:
The patent combines multiple steel columns and bracing members into a single integrated localization steel frame structure. The steel frame acts as a unified component that replaces multiple individual members, simplifying the assembly process and reducing construction complexity while maintaining structural integrity
Solution Approach 2:
The patent segments the foundation system into two distinct parts: the concrete ring beam for load bearing and the integrated steel frame for localization and positioning. This segmentation allows each component to perform its specific function efficiently, reducing overall construction complexity
2Manufacturing precision
If anchor bolts are embedded into ring beams for joining steel columns, then the steel frame can be assembled, but the embedding procedure becomes complicated requiring precise positioning
Solution Approach 1:
The patent incorporates pre-determined positioning features directly into the integrated steel frame structure during manufacturing. The steel frame includes built-in alignment elements and positioning holes that eliminate the need for complex on-site surveying and positioning of anchor bolts, achieving high positioning accuracy through pre-prepared features
Solution Approach 2:
The integrated steel frame acts as an intermediary component between the concrete ring beam and the individual steel columns/bracing members. It provides a standardized interface with pre-positioned connection points, simplifying the joining process and eliminating the need for precise field positioning of multiple anchor bolts
3Productivity
If multiple steel columns and bracing members are fixed with embedded anchor bolts, then the structure can be assembled, but the localization work becomes time consuming and strenuous
Solution Approach 1:
The patent merges multiple individual steel columns and bracing members into a single integrated steel frame structure. This consolidation reduces the number of separate positioning and fixation operations required, significantly improving productivity by treating the entire localization system as one unit rather than multiple separate components
Solution Approach 2:
The integrated steel frame is manufactured with pre-determined positioning features and connection points before site assembly. This preliminary preparation of localization features eliminates time-consuming on-site surveying and positioning work, allowing for rapid installation and significantly reducing the time and effort required for localization
4Ease of manufacture
If the integrated localization steel frame is used, then construction cost is reduced and work efficiency is promoted, but the structure requires accurate linear localization
Solution Approach 1:
The integrated steel frame includes pre-manufactured positioning features such as alignment holes, guide edges, and standardized connection points that ensure accurate linear localization during assembly. These pre-prepared features guide the positioning process and maintain high dimensional accuracy without requiring complex on-site measurement and adjustment procedures
