Construction Slab Insert With Spring Anchor Bolt
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing inserts for construction slabs require separate assembly of anchor bolt members after mold removal, which is inconvenient and time-consuming.
Innovation Solution
An insert with a main body featuring an operation space, a support block with a withdrawal hole, a spring member to elastically support the anchor bolt, and a cover member to seal the space, allowing the anchor bolt to be withdrawn externally when the mold is removed, along with locking grooves and cutting grooves for length control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the insert uses a conventional configuration without an embedded anchor bolt, then the mold can be removed cleanly without remaining components, but the anchor bolt must be assembled separately after mold removal which is inconvenient and time-consuming
Solution Approach 1:
The anchor bolt is pre-assembled and embedded within the insert body before mold removal. The insert is designed with a cavity that holds the anchor bolt in place during concrete pouring and mold removal, eliminating the need for separate post-assembly operations.
Solution Approach 2:
The anchor bolt and insert are combined into a single integrated component. The anchor bolt is embedded within the insert body, merging two separate elements (insert and anchor bolt) into one unified structure that simplifies installation and eliminates separate assembly steps.
2Ease of operation
If the anchor bolt is embedded in the insert body, then separate assembly after mold removal is eliminated, but the anchor bolt needs to be withdrawable through a controlled opening for proper installation
Solution Approach 1:
The withdrawal hole is pre-formed in the insert body at the correct position and orientation before installation. This preliminary preparation ensures that when the anchor bolt needs to be accessed, it can be withdrawn through the pre-positioned opening without requiring additional drilling or positioning operations.
3Productivity
If the insert structure is simplified for easy mold removal, then the anchor bolt cannot be pre-assembled and embedded, requiring separate assembly operations
Solution Approach 1:
The insert and anchor bolt are merged into a single pre-assembled unit. This integration allows the entire assembly to be installed in one operation during mold removal, eliminating the time loss associated with separate anchor bolt assembly operations and improving overall productivity.
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
Facilitates easy withdrawal and length control of the anchor bolt, eliminating the need for separate assembly and ensuring a firm fixing state, while allowing for adjustable length and compatibility with various slab thicknesses.
Implementation Method 1
a spring member, and a cover member coupled to an upper portion of the main body so as to seal the operation space; an anchor bolt member inserted into the operation space to be pressed to the withdrawal hole by the spring member

AI summary
Disclosed is an insert for a construction slab which includes: main body in which an operation space having a planar cross-section of a polygonal shape in an axial direction is formed; a support block which is formed at a lower side of the main body to have a diameter smaller than that of the main body and has a withdrawal hole at an inner side thereof so that a support stepped portion is formed at a lower end of the operation space; a support plate formed at the lower side of the support block to be in contact with a mold; a cover member coupled to an upper portion of the main body so as to seal the operation space; and an anchor bolt member inserted into the operation space to be pressed to the withdrawal hole by a spring member.
