6. The support structure of claim 1 , wherein the pedestal includes:

a base portion seated on top of the beam element bracket;

a head portion supporting the floor panel; and

a connection portion inserted into the base portion and the head portion, and including a height-adjustable thread.

7. The support structure of claim 6 , further comprising:

a pedestal connection portion passing through the beam element bracket and the base portion, and coupled to the first beam element to connect the pedestal, the beam element bracket, and the first beam element to each other.

8. The support structure of claim 7 , wherein the pedestal connection portion is a T-bolt having a T-shaped head.

9. The support structure of claim 7 , wherein the base portion includes a first receiving hole receiving the pedestal connection portion,

the beam element bracket includes a second receiving hole receiving the pedestal connection portion, and

the pedestal connection portion connects the pedestal and the beam element bracket to each other by passing through the first and second receiving holes.

10. The support structure of claim 9 , wherein the first receiving hole includes a first circular portion and a first elliptical portion,

a diameter of the first circular portion is equal to or greater than a length of the head of the pedestal connection portion, and

the pedestal connection portion is movable along the first elliptical portion such that the pedestal is horizontally movable on the beam element bracket.

11. The support structure of claim 9 , wherein the first beam element includes a first slide groove receiving the pedestal connection portion, and

the pedestal connection portion is inserted into the first slide groove by passing through the first and second receiving holes.

12. The support structure of claim 6 , wherein the head portion includes a seat guide portion protruding from an upper surface of the head portion by a predetermined thickness, and fixing the floor panel.

13. The support structure of claim 1 , further comprising:

stringers connected to the pedestal and extending in the first direction and the second direction, wherein

the stringers support the floor panel together with the pedestal.

14. An access floor system, comprising:

a floor panel; and

a support structure supporting the floor panel,

wherein the floor panel includes multiple unit panels, and

the support structure includes:

a first beam element disposed in a first direction;

a second beam element disposed in a second direction perpendicular to the first direction;

a post supporting the first beam element and the second beam element;

a beam element bracket seated on top of the first beam element and the second beam element, and connecting the first beam element and the second beam element to each other; and

a pedestal seated on top of the beam element bracket and supporting the unit panels.

15. The access floor system of claim 14 , wherein the pedestal includes:

a base portion seated on top of the beam element bracket;

a head portion supporting the floor panel; and

a connection portion inserted into the base portion and the head portion, and including a height-adjustable thread.

16. The access floor system of claim 15 , further comprising:

a pedestal connection portion passing through the beam element bracket and the base portion, and coupled to the first beam element to connect the pedestal, the beam element bracket, and the first beam element to each other.

17. The access floor system of claim 16 , wherein the base portion includes a first receiving hole receiving the pedestal connection portion,

the beam element bracket includes a second receiving hole receiving the pedestal connection portion, and

the pedestal connection portion connects the pedestal and the beam element bracket to each other by passing through the first and second receiving holes.
