Steel Pipe Socket for Direct Pile-Column Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for connecting steel pipe piles and columns, such as using a concrete bottom plate, are cumbersome, leading to prolonged construction periods and increased costs, especially in fast-track construction projects, due to the difficulty in ensuring verticality and horizontality without causing eccentricity.
Innovation Solution
A steel pipe socket with a socket supporting portion, socket insertion portions with grooves, fastening members, a horizontality maintaining member, and reinforcing ribs that allow for direct connection of steel pipe piles and columns without concrete, ensuring verticality and horizontality by adjusting the socket supporting portion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a concrete bottom plate is used to connect steel pipe piles and columns, then verticality and horizontality can be ensured, but construction period is significantly prolonged and construction cost increases
Solution Approach 1:
The invention extracts and eliminates the concrete bottom plate from the connection system, replacing it with a steel pipe socket that directly connects the steel pipe pile and column. This removes the time-consuming concrete pouring, curing, and grouting processes while maintaining the precision functions through the socket's structural design with horizontal adjustment capabilities.
Solution Approach 2:
The invention changes the material parameter from concrete to steel, and introduces adjustable horizontal parameters in the socket structure. The socket includes horizontal adjustment mechanisms that allow precise control of horizontality and verticality without requiring concrete curing time, thus resolving the contradiction between precision and construction time.
2Manufacturing precision
If a concrete bottom plate is used to connect steel pipe piles and columns, then verticality and horizontality can be ensured, but construction cost increases
Solution Approach 1:
The invention extracts the concrete bottom plate from the system and replaces it with a steel pipe socket. This eliminates material costs for concrete, formwork, reinforcing bars, and grout, while reducing labor costs associated with multiple construction stages. The steel socket provides the necessary precision functions in a single manufacturable component.
Solution Approach 2:
The steel pipe socket serves multiple functions: it provides structural connection, ensures verticality, maintains horizontality through adjustment mechanisms, and replaces the need for concrete bottom plates, formwork, and grouting. This multi-functionality consolidates multiple costly construction processes into a single efficient operation.
3Strength
If steel pipe piles are driven and trimmed to ensure proper connection, then attachment force can be improved, but additional work processes are required increasing construction complexity
Solution Approach 1:
The invention merges the connection function, strength provision, and alignment assurance into a single steel pipe socket component. The socket integrates the attachment mechanism with the structural connection element, eliminating the need for separate concrete bottom plates, formwork, and grouting processes, thus reducing overall process complexity while maintaining or enhancing attachment force.
