Claims

[Scope of utility model registration request]

In a double floor structure in which a floating floor is formed by placing floor panels on the pedestals of support legs that are erected in a grid pattern on the foundation floor surface, locking parts and screw rods are attached to the protrusions on the pedestals. One locking part of the level adjustment bolt is locked, and the other screw rod is inserted into the adjustment hole drilled in the floor panel, and moved up and down in the adjustment hole to adjust the floating floor surface. A level adjustment bolt for level adjustment, characterized in that an insertion portion having a smaller diameter than the outer diameter of the screw rod is provided at the tip of the screw rod, and a tool insertion opening is carved in the insertion portion. Bolts for level adjustment of floating floor surfaces in floor structures.
