Title: DOUBLE FLOOR STRUCTURE
Abstract:
This double floor structure has a plurality of floor panels, a joining member, and a beam member. The joining member has a support surface for placing an installation object thereon at a substantially same height as the top surfaces of the plurality of floor panels or at a position lower than the top surfaces of the plurality of floor panels, and a fixation hole for fixing the installation object is provided to the support surface. The beam member is at least partially disposed below the joining member and the joining member is mounted thereto. In a first direction toward the joining member from the floor panel that is closest to the joining member among the plurality of floor panels, at least at a position far from a part of the fixation hole as viewed from the floor panel, the beam member supports the joining member from below.
