Locking Pin Joint System for Precast Ground Beams
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The joining of precast ground beams at construction sites is difficult, time-consuming, and lacks accuracy, primarily due to the need for grout and complex alignment processes.
Innovation Solution
A joint system comprising locking dowels and housings with transverse holes, allowing for the secure connection of precast ground beams without grout, facilitating quick and accurate assembly through the use of locking pins.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If precast ground beams are joined using traditional grout methods, then the connection can be achieved, but the joining process becomes difficult and time-consuming
Solution Approach 1:
The patent replaces the chemical grout-based joining system with a mechanical locking system consisting of locking dowels, locking housings, and locking pins. This mechanical substitution eliminates the need for grout application, curing time, and complex alignment procedures, thereby significantly reducing installation time and improving ease of operation while maintaining connection strength
Solution Approach 2:
The joining system is divided into separate modular components: locking dowels embedded in one ground beam, locking housings embedded in the other ground beam, and removable locking pins. This segmentation allows for pre-positioning of components during manufacturing and simple field assembly, eliminating the need for on-site grout mixing and application while maintaining secure connections
2Manufacturing precision
If traditional grout methods are used for joining precast ground beams, then connections can be made, but accuracy in joining is poor
Solution Approach 1:
The locking dowels and locking housings are pre-positioned and embedded into the ground beams during the concrete casting process. This preliminary action ensures that the joining components are already accurately positioned before the ground beams are installed on site, eliminating the need for complex alignment procedures and ensuring high joining accuracy
Solution Approach 2:
The locking pins serve as intermediaries that connect the locking dowels and locking housings. The pins guide the alignment process by fitting into precisely positioned holes, acting as a mechanical mediator that ensures accurate positioning of the ground beams relative to each other without requiring complex alignment tools or procedures

AI summary
The present invention relates to a joint system for joining precast ground beams (201, 202, 305, 306, 307, 308) together. The joint system comprises a first joint part (101) for a first precast ground beam (201, 305, 306) and a second joint part (102) for a second precast ground beam (202, 307, 308), which joint parts (101, 102) can be locked together by using at least one locking pin (103, 104). The present invention also relates to a foundation for a building.
