Document Type and Number:
WIPO Patent Application WO/2018/212460
Kind Code:
A1
Abstract:
The present invention provides an insert for a construction slab, wherein the insert can be commonly used in a plywood mold, an aluminum (steel) mold, and a deck plate (hereinafter, referred to as a 'mold') and provides functionality allowing an embedded anchor bolt member to be withdrawn to the outside when removing the mold, thereby being capable of eliminating the inconvenience of separately assembling the anchor bolt following mold removal. That is, the present invention includes: a main body having an operation space having a planar cross-section that is a polygonal shape in the axial direction formed therein; a support block disposed below the main body and having a smaller diameter than the main body, and having a withdrawal hole formed such that a support stepped portion is formed inward on the lower end of the operation space; a support plate formed below the support block to contact the mold; a cover member coupled to the upper portion of the main body to seal the operation space; and an anchor bolt member inserted into the operation space and pressed toward the withdrawal hole by a spring member.
