Abstract
The present invention relates to a double flooring structure which may be used to constitute the floor of a computer room or the like in a building. The double flooring structure has excellent constructibility, high earthquake resistance, a wide underfloor space and excellent resistant to deformation under load. The double flooring structure of the present invention comprises bases secured to a floor surface, columnar leg members pivotally standing on the bases, respectively, stringers each stretched between a pair of adjacent columnar leg members, floor panels supported on the stringers, and fastening means for securing the floor panels to the columnar leg members. The pivot point of each columnar leg member is disposed near the floor surface. When the floor panels are secured to the columnar leg members by the fastening means, the columnar leg members, the stringers and the floor panels constitute in combination one rigid body. Accordingly, a load which is applied to each floor panel is dispersed effectively and efficiently. If a lateral load is applied to the double flooring structure of the present invention, the columnar leg members are urged to pivot. However, since the pivot point of each columnar leg member is disposed near the floor surface, it is possible to minimize the bending moment that acts on that portion of each base which is bonded to the floor surface.
