Concrete Anchor Driver Tool for Rotary Hammer Drills
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of concrete anchors in concrete or masonry surfaces is inefficient due to the need for multiple tools, such as hammers, drills, and wrenches, which requires frequent position changes and can cause discomfort and injury, and often results in damage to the anchor components.
Innovation Solution
A concrete anchor driver tool that integrates a rod with a multi-faceted bolt head and a socket, along with a compressible spring, which allows for hammer drilling and nut rotation in a single tool, preventing nut spinning and ensuring maximum anchor penetration without manual hammering or wrenching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple tools (drill, hammer, wrench) are used to install concrete anchors, then the installation can be completed, but the installer must frequently change positions and tools, causing discomfort and injury
Solution Approach 1:
The patent combines multiple tools (drill, hammer, wrench) into a single integrated concrete anchor driver tool. The tool features a rod with a striking end for hammering, a threaded shaft for drilling, and a hexagonal drive end for wrenching, allowing all installation operations to be performed with one tool from a single position.
Solution Approach 2:
The concrete anchor driver tool is designed as a universal tool that performs multiple functions: it can drill holes, hammer anchors into place, and tighten nuts onto anchors. This multi-functionality eliminates the need for separate tools and allows the installer to remain in one position throughout the installation process.
2Productivity
If a hammer is used to pound the concrete anchor bolt into the hole, then the anchor is installed, but the nut and threads of the concrete anchor can be damaged
Solution Approach 1:
The tool separates the hammering function from the anchor components by using a dedicated striking end on the rod that contacts only the head of the anchor bolt, not the nut or threads. This segmentation ensures that the hammering force is applied precisely where needed without damaging other parts of the anchor assembly.
Solution Approach 2:
The rod acts as an intermediary between the hammering force and the anchor bolt. The striking end of the rod transmits the hammering force to the anchor head while the threaded shaft portion engages with the anchor threads, protecting them from direct impact damage during the installation process.
3Productivity
If the concrete anchor bolt is fully pounded into the hole, then the anchor is installed, but a separate wrench must be used to rotate the nut tight
Solution Approach 1:
The tool merges the hammering and wrenching functions into a single integrated device. The rod provides both a striking end for hammering the anchor into place and a threaded shaft with hexagonal drive end for wrenching the nut, eliminating the need for a separate wrench tool.
Solution Approach 2:
The concrete anchor driver tool serves as a universal tool that replaces both the hammer and wrench. After pounding the anchor into the hole, the same tool can be used to rotate and tighten the nut onto the anchor shaft, completing the installation process with one tool.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This tool reduces the number of tools needed, minimizes physical strain by allowing standing installation, and prevents damage to anchor components by maintaining the nut's position and securely driving the anchor into the concrete.
Implementation Method 1
a spring, positioned between a spring retaining device and the socket, and where the spring biases the drive end of the socket against the multi-faceted bolt head end of the rod

AI summary
The disclosed concrete anchor driver tool is coupled to a rotary hammer drill to install a concrete anchor. The tool includes a rod having multi-faceted bolt head end, such as a hexagonal bolt head end, and a socket having a multi-faceted opening in the socket end of the socket. The socket is slipped over the rod and held against the bolt head end of the rod by a compressible spring. The concrete anchor driver tool is operated by coupling the concrete anchor driver tool to a rotary hammer drill, slipping the socket over the concrete anchor, and operating the drill in the hammer mode to hammer the concrete anchor bolt into the concrete. The rotary hammer drill is then put in rotate mode and used to rotate the concrete anchor driver tool rod, which rotates the socket, which, in turn, tightens the nut on the concrete anchor.
