A device which is installed onto an ingrown nail of a human toe to correct the ingrown nail, includes a support member affixed to the ingrown nail, and a correcting member supported by the support member and effecting force on the ingrown nail toward the correcting direction for the ingrown portion of the nail. The correcting member may be formed of a superelastic material which is shape-memory-treated to memorize a first shape, and which is deformed to a second shape different from the first shape so as to be installed onto a surface of the ingrown nail of the human toe in the second shape.

Device for correcting an ingrown nail

A fire protecting structure of a channel portion of a plastic piping in a fire partition wherein the plastic piping is inserted in a through hole formed in the fire partition and the through hole is filled with a refractory material, wherein a support means having a region, which makes a refractory material to come in contact with the outer surface of the plastic piping, and portions for supporting an intumescent material, the support means being arranged around the plastic piping and the refractory material being filled in the region of the support means to come in contact with the outer surface of the plastic piping.

Fire protecting structure of channel portion of plastic piping in a fire

A fire/smoke protection structure for cable channel portion in a floor or wall includes thermal expansion composite molded members each molded into a desired shape and filled in a gap defined between a cable or the like and the channel portion. Each thermal expansion composite molded member is either a member obtained by coating a non-refractory material on the outer surface of a core consisting of a fire retardant resin foaming body compressed to 90% or less of a normal volume, or a member obtained by coating a thermally foaming fire retardant composition on the outer surface of a core consisting of a refractory material and molded into a desired shape. The fire/smoke protection structure can be easily constructed, maintained and reconstructed at a construction site and can be completely and reliably achieved.
