<p>Disclosed herein is a multi-purpose sectional block which is easy in assembly and provides excellent durability, thereby being applicable for interior of a building or for armoring of the building. The sectional block includes: a block having two fixing holes symmetrically formed therein along the central line thereof; and bolts, each bolt having a bolt head formed on the upper portion thereof and having a threaded hole axially perforated therein, and a threaded bar formed on the lower portion thereof, whereby the bolts are securely fit into the fixing holes of the block. The fixing hole includes a hole drilled in the lower portion thereof for inserting the threaded bar thereto, a bolt insertion hole formed in the upper portion of the hole for inserting the bolt head thereto in such a way as for the bolt head to be depressed inside the block, and a tool insertion hole formed on the upper portion of the bolt insertion hole. The tool insertion hole is formed to be larger than the bolt insertion hole so that a user manipulates the bolt with a tool in a state where the bolt head is inserted into the fixing hole. The block includes a recess part formed on the edge thereof for providing a beautiful outward appearance and for forcedly fitting a shelf thereto.</p> |
