a bolting robot configured to fasten the pad and the floor by using a fastener, the fastening being performed after the floor is mounted on the pad.

2 . The unmanned access floor construction system of claim 1 , wherein the pad installation robot comprises:

a first transporter configured to move the first installation arm.

3 . The unmanned access floor construction system of claim 2 , further comprising an adhesive supply part configured to supply an adhesive to a bottom surface of the pad.

4 . The unmanned access floor construction system of claim 3 , wherein the first installation arm comprises:

a first gripper configured to suction the pad; and

a second gripper configured to surround a side surface and a bottom surface of the pad suctioned to the first gripper.

5 . The unmanned access floor construction system of claim 4 , wherein the first gripper uses a vacuum suction method, and

the second gripper comprises:

a first guide part protruding from an end of the first installation arm in a downward direction; and

a second guide part extending from the first guide part in an inward direction,

wherein the first guide part is hinged with respect to the first installation arm.

6 . The unmanned access floor construction system of claim 5 , wherein the second guide part is:

hinged in the inward direction in a state in which the pad is suctioned to the first gripper; and

hinged in an outward direction in a state in which the pad is separated from the first gripper.

7 . The unmanned access floor construction system of claim 6 , wherein the pad installation robot further comprises a main body to which the first install arm is mounted,

wherein the adhesive supply part is disposed on the main body, and

a discharge hole through which the adhesive is discharged is defined in the adhesive supply part.

8 . The unmanned access floor construction system of claim 6 , wherein the floor installation robot comprises:

a transportation unit configured to transport the floor in a loaded state; and

an installation unit configured to mount the floor disposed on the transportation unit to the pad.

9 . The unmanned access floor construction system of claim 8 , wherein the installation unit comprises:

the second detection sensor configured to sense the mounting position of the floor;

a second installation arm configured to move the floor to the mounting position; and

a second transporter configured to move the second installation arm.

10 . The unmanned access floor construction system of claim 9 , wherein the bolting robot comprises:

a third detection sensor configured to sense an insertion hole to which the fastener is inserted;

a third installation arm configured to move the fastener to the insertion hole; and

a third transporter configured to move the third installation arm.

11 . The unmanned access floor construction system of claim 10 , wherein the fastener is a bolt,

the insertion hole is defined in the pad and the floor, and

the unmanned access floor construction system further comprises a bolting part configured to fasten the bolt to the insertion hole.

12 . The unmanned access floor construction system of claim 11 , wherein the construction robot comprises:

a position sensor; and

a distance sensor.

13 . A method for constructing an access floor by using the unmanned access floor construction system of claim 12 , comprising:

a first step of constructing the installation frame, an elevator, and a peripheral slab; and

a second step of moving the construction robot to the peripheral slab by using the elevator.

14 . The method of claim 13 , further comprising, after the second step:

a third step of attaching the pad to the frame by using the pad installation robot;

a fourth step of mounting the floor to the pad by using the floor installation robot; and

a fifth step of fastening the floor to the pad by inserting the bolt to the insertion hole using the bolting robot.

15 . The method of claim 14 , wherein the fourth step comprises:

an alignment step of allowing the transportation unit and the installation unit to approach the mounting position; and

a mounting step of lifting the floor loaded on the transportation unit by the second installation arm and mounting the floor to the mounting position.
