Buckstay connecting system

A buckstay connecting system for connecting a vertical buckstay installed in a height direction of a furnace with a horizontal buckstay installed in a width direction of the furnace, the vertical buckstay and the horizontal buckstay being capable of moving relative to each other in a vertical direction in accordance with deformation of the furnace, the buckstay connecting system comprising:

• a socket part that is fixed to the horizontal buckstay being separated from a lower end of the vertical buckstay between the lower end of the vertical buckstay and the horizontal buckstay;
• and
• an insertion part that is fixed to a lower portion of the vertical buckstay, is inserted into the socket part so as to be able to slide in the vertical direction during relative movement of the vertical buckstay and the horizontal buckstay, inhibits an inclination of the horizontal buckstay with respect to a horizontal direction of the furnace, and is allowed to be fastened to the socket part,
• wherein the socket part includes a web and a pair of flanges, the pair of flanges being connected to both ends of the web in the horizontal direction,
• the insertion part includes a pair of central plates and two pairs of bent portions, a pair of bent portions being connected to both ends of each central plate in the horizontal direction,
• the pair of central plates is disposed so that the web is inserted therebetween in a thickness direction of the web, and
• the pair of bent portions is positioned between the pair of flanges, and is disposed so as to contact the pair of flanges.
