Raised floor and assembling method thereof

A method of assembling a raised floor, comprising the following steps:

• Step 1:
• cleaning a base layer:
• preparing, classifying, placing and keeping clean construction tools, construction materials such as floor boards and a support leg, and simultaneously clearing garbage and dust on the ground, and leveling the ground;
• Step 2:
• laying down a horizontal line:
• before assembly, planning height of the raised floor according to the environment of the construction site and the use requirement, and then snap-lining through an ink fountain, and forming a horizontal line at an installed position, namely, a floor laying baseline;
• Step 3:
• installing the beams:
• respectively installing the leveling beam (2) and the frame beam (5);
• Step 4:
• installing the leveling support leg:
• finding positions corresponding to the preformed holes (17) according to the size of the raised floor, and arranging the leveling screws (3) at the positions, so as to fix a support point of the floor board, and adjusting all the leveling screws (3) to the height approximately equal to a top end of the leveling beam (2);
• and
• Step 5:
• laying the floor board, laying the raised floor boards (1), laying the floor board along the floor laying baseline, laying the raised floor boards (1) close to the positions of the leveling beam (2), and leaving the reserved expansion joint (4) so as to prevent the floor board from cracking or damaging its integrated structure due to climate and temperature changes, after laying the bottom plate close to the leveling beam (2), laying it continuously with the raised floor boards (1), inserting the insertion rod (36) in the leveling screws (3) into the sockets (18), support and fixing the raised floor boards (1) through the leveling screws (3), and keeping the preformed holes (17) above the leveling screws (3), and finely adjusting the height of the leveling screws (3) with the tools.
