That is, the bottom panel 100 is formed in a flange shape having a constant width at an edge portion thereof, and the frame mounting portion 130 is mounted on the upper surface of the frame 200 while being coupled thereto.

The bottom panel 100 according to the present invention includes a plurality of ribs protruding from the bottom of the top plate 110 on the inside of a square pore formed by the frame 200 and the top of the frame 200 So as to have a more rigid coupling state.

As shown in FIGS. 3 and 4, when the bottom panel 100 according to the present invention is installed, a square top plate 110 and a top plate 110 And ribs having various shapes integrally formed on the bottom surface.

FIG. 8A is a perspective view of the frame rib 131 in a case where the frame rib 131 is installed in a frame having a relatively low rigidity so as to increase the height and thickness of the frame rib 131, .

It should be noted that the frame rib 131 may be increased in height to form the frame rib reinforcement 132, but the thickness of the frame rib 131 may be increased to reinforce the rigidity.

8B) is designed such that the thickness of the frame rib 131 is relatively thin and the height thereof is relatively low when the rigidity of the frame is relatively high.

The frame mounting portion 130 provided at the corner of the floor panel 100 is seated on the upper surface of the frame 200 to be more stably installed.

Reference numeral 190 denotes a tile as a finish flooring material attached to the upper surface of the floor panel 100.

In the present invention, the frame 200 on which the bottom panel 100 of aluminum material is installed is generally formed in the shape of a pipe, and is usually made of iron or aluminum. The sectional modulus of the frame 200 and the characteristics of the material It differs from the aluminum floor panel manufactured by the casting method.

Therefore, in order to solve the problem that the aluminum bottom panel 100 is broken near the frame 200 due to the difference in deformation amount with respect to the load when the heavy load equipment is moved from above the installed aluminum floor panel, The reinforcing rib 120 is positioned at a position close to the frame 200 and has a fracture prevention reinforcing round portion 141 having the largest allowable dimension at a position connected to the frame rib 131, So that breakage of the panel 100 does not occur.
