3 and 4, the double floor system 50 according to an embodiment of the present invention is a post 100 is installed on the base floor, the stringer 200, the stringer 200 is installed on the upper side of the post 100 It includes a floor panel 300 is installed above.

The post 100 stably supports the stringer 200 and the floor panel 300, and includes a base plate 110, a post column 120, and a post head 130.

The base plate 110 has a flat plate shape and includes a plurality of anchor holes 111 to be fixed to the ground by an anchor bolt or the like.

Post column 120 is coupled to the upper side of the base plate 110. The post column 120 may be formed of a hollow body. At this time, a post cap may be provided on the upper end of the post column 120 to prevent foreign substances from being introduced into the post column 120 while the control nut described later is disposed. Can be.

In the embodiment of the present invention, the post column 120 is formed in a cylindrical shape, but the shape of the post column 120 need not be limited as long as it has a strength capable of supporting the double bottom panel. For example, the post column 120 may be formed in a polygonal column shape having a triangular or quadrangular cross section as necessary.

The post head 130 is formed in the shape of a rectangular flat plate so as to be in close contact with the bottom surface of the stringer 200, and is coupled to the upper and lower heights of the post column 120 via the screw shaft 140. For example, the adjusting nut is coupled to the screw shaft 140 to adjust the height of the post head or to fix the height of the post head.

3 and 4, the stringer 200 is mounted on the post head 130 to support the floor panel 300.

The stringers 200 are spaced apart from each other at a predetermined distance a in one direction, for example, in the X-axis direction. The arrangement interval a of the stringer 200 may correspond to, for example, the width of one floor panel 300.

In one embodiment, the stringer 200 is formed of a metal material having a rectangular cross section, but is not limited thereto. That is, H-shaped steel, L-shaped steel, a section steel having a polygonal cross section, etc. may be selectively used as necessary.

An end cap (not shown) may be coupled to the end of the stringer 200 to prevent moisture or foreign matter from entering into the stringer.

5 and 6, the floor panel 300 is installed above a predetermined height from the bottom of the foundation and is supported by the post 100 and the stringer 200. The floor panel 300 may be formed of a metal material, and preferably, may be formed of an aluminum material having high durability.

The floor panel 300 includes a body 310, a frame rib 320, a main rib 330, a sub rib 340, a seating rib 350, and a reinforcing rib 360.

The body 310 may be formed as a rectangular flat plate when viewed in plan, and the body 310 may be formed with a plurality of through holes for the distribution of air. The body 310 has a first side 311 and a second side 312 opposite the first side. When the floor panel is installed, the first surface 311 may be an upper surface, and the second surface 312 may be a lower surface. The first surface 311 of the body 310 is a tile flooring 370 is disposed, the second surface 312 is the frame rib 320, the main rib 330, the sub rib 340, the seating rib 350 and reinforcing ribs 360 are disposed. The body 310, the frame rib 320, the main rib 330, the sub rib 340, the seating rib 350 and the reinforcing rib 360 may be formed in one piece, or may be separately formed and then joined to each other. May be The frame rib 320 protrudes a predetermined height in a downward direction at a position close to the edge of the body 310.

Frame rib 320 is provided inside the predetermined interval from the edge of the body 310, is arranged in a rectangular structure in plan view to form the overall frame.

The main rib 330 is to reinforce the strength of the body 310, the main rib 330 is disposed in a plurality of grid-shaped inside of the frame rib 320 is arranged in a square. A plurality of unit cells are partitioned inside the frame rib 320 by the main rib 330. Each unit cell is formed in a rectangular structure.

The sub rib 340 assists the main rib 330 to reinforce the strength of the body 310. The sub rib 340 has a cross (+) inside each unit cell partitioned by the main rib 330. ) Is arranged in the form. The protruding length of the sub rib 340 based on the body 310 may be shorter than the protruding length of the main rib 330. For example, the length of the sub rib 340 may be formed to 1/3 to 1/2 of the length of the main rib 330, thereby inducing a material saving when manufacturing a floor panel from an expensive material such as aluminum. Can be. That is, when the rigidity of the main rib 330 is relatively high, the protruding length of the sub rib 340 may be relatively reduced to reduce the overall weight of the floor panel. Meanwhile, in order to further increase the overall strength of the floor panel, the main ribs 330 may be alternately disposed instead of the sub ribs 340 at the center of the horizontal side and the center of the vertical side of the body 310.

The mounting rib 350 is to be seated on the upper surface of the stringer 200, the mounting rib 350 is formed to protrude a predetermined length on the edge of the body 310. That is, the mounting rib 350 is disposed to be spaced apart from the frame rib 320 on the outside of the frame rib 320. The length of the seating rib 350 based on the body 310 may be formed as 1/4 to 1/3 of the length of the frame rib 320. Therefore, in the related art, when the heavy load equipment is moved on the floor panel, breakage occurs in a portion where the floor panel is seated on the stringer due to the difference in the deformation amount with respect to the load. By mounting the mounting ribs 350 provided on the stringer to the stringer, it is possible to prevent deformation or breakage of the floor panel and to withstand the load (for example, 1000 kgf design load) applied to the floor panel. Meanwhile, a chamfered surface 351 may be formed on the lower outer surface of the mounting rib 350 to be inclined toward the inner side of the mounting rib 350 toward the lower direction. The chamfered surface 351 may improve fire resistance and aesthetics of the floor panel, prevent breakage due to impact, and prevent worker damage due to sharp edges.

The reinforcing rib 360 interconnects the frame rib 320 and the seating rib 350 to reinforce the rigidity of the body 310. That is, one end of the reinforcing rib 360 is connected to the outer surface of the frame rib 320 and the other end is connected to the inner surface of the seating rib 350. The reinforcing rib 360 may further reinforce the rigidity of the body 310 by providing the curved portion 361 at the bottom thereof. The curved portion 361 may be formed convexly to the lower side, that is, the opposite side of the body 310, but concave to the upper side, that is, the body 310 side to reduce the material while improving structural rigidity. It is preferable to form. As such, the reinforcing rib 360 may be provided on the second surface 312 of the body 310, and the curved portion 361 may be provided on the reinforcing rib 360. The stress can be uniformly distributed, thereby significantly increasing the durability of the floor panel.

The foregoing description of the present invention is intended for illustration, and it will be understood by those skilled in the art that the present invention may be easily modified in other specific forms without changing the technical spirit or essential features of the present invention. will be.

In other words, the above-described embodiments are to be understood in all respects as illustrative and not restrictive. For example, each component described as a single type may be implemented in a distributed manner, and similarly, components described as distributed may be implemented in a combined form.
