Spring Clip Masonry Plate Setter for Grout Cavity Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for securing steel plates against concrete masonry blocks during the grouting process are labor-intensive and unsatisfactory, relying on makeshift temporary supports.
Innovation Solution
A system involving masonry blocks with inner grout cavities and Nelson studs, where spring clips compress between the block walls and stud heads to secure the steel plate as the grout cavity is filled, permanently embedding the studs and plate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If makeshift temporary supports are used to prop up steel plates during grouting, then the steel plate can be held in position, but the process becomes labor and time consuming
Solution Approach 1:
The spring clips are pre-installed on the steel plate before grouting begins. This preliminary action eliminates the need for temporary supports during the grouting process, as the clips are already in position to secure the plate. The clips are temporarily compressed and then released to engage with the masonry blocks, providing immediate stabilization without requiring additional labor during the critical grouting phase.
Solution Approach 2:
The spring clips are designed to be self-actuating through the grouting process itself. As grout is injected into the cavity, the expanding grout automatically compresses the spring clips against the masonry blocks, causing them to expand and lock onto the blocks. This self-service mechanism eliminates the need for external temporary supports and reduces labor requirements, as the system uses the grouting process itself to activate the securing mechanism.

AI summary
A system for setting and securing metal plate on an outer wall of concrete masonry, includes upper and lower masonry blocks with side walls and end walls forming an inner grout cavity. The metal plate has Nelson studs extending from it, each having a head on its outer end The studs extend from the plate, through a masonry side wall, into the grout cavity. A spring clip in the grout cavity compressed between a masonry block side wall and the stud head urges the stud and plate inward to secure the plate against the masonry as the grout cavity is filled with grout.
