PROBLEM TO BE SOLVED: To provide a connection reinforcing tool having sufficient reinforcing strength to improve the earthquake resistance of a house. SOLUTION: This connection reinforcing tool 100 comprises a base plate 102 and a cover plate 104 which are a pair of sheet members. The base plate 102 comprises a first through-hole 200 for inserting a lag screw 206 and a second through-hole 202 for inserting an anchor bolt 110. After the base plate 102 is fixed to a column P and a foundation B by the lag screw 206 and the anchor bolt 110, the cover plate 104 is mounted on the base plate 102. The cover plate 104 has the effects of preventing the dropping-out of the lag screw 206 and improving the reinforcing strength by the double structure with the base plate 102.
