An access floor support assembly is provided to cut down on the cost of materials and to secure durability by making a head of a pedestal thin and to secure smoothness for installing a head of each pedestal and a head smoothly as a whole. An access floor support assembly includes a pedestal(10) placed on each apex of a quadrangle having the appointed size and composed of a base plate contacted with the ground, a lower support risen to the upper part of the base plate and provided with a female thread, an upper support provided with a male thread to couple with the lower support and having a height adjustment function and a head(17') put on the upper support, a stringer(20) connecting a pedestal and a pedestal, and a panel put on a head of the pedestal and the upper part of the stringer, wherein a reinforcement member such as a reinforcement square pipe(40A) is formed to connect a pedestal and a pedestal and introduced in the right place to reinforce the whole access floor support assembly, and the reinforcement square pipe is coupled to fastening parts(17C') put symmetrically at two sides of the head respectively and a relatively short bolt(B1) is screwed to fastening holes(17c',41a) respectively. In addition, a cushion pad(20) is put on the head of the pedestal to reduce a minute height difference of a central projecting part and the fastening part of the head, to cover up a gap of the head, the stringer and the reinforcement square pipe, and to supplement the function of sound insulation and impact transfer reduction with shock absorbing force. |
