However, since the adhesive effect of the adhesive 20 tends to decrease over time, when an external force such as an earthquake is applied, the fixing plate b3 of the support leg B peels off from the foundation floor D, and the support leg Not only will the installation condition of B become unstable, but there is also a risk of it falling over. Moreover, since the upper surface (panel mounting surface) of the panel support plate b1 of the support leg B that supports and supports the corner portion of the floor panel C is formed flat, the support plate b1
A step is created between the edges 21 of adjacent floor panels C by mounting and supporting the corner portions on top, which not only spoils the interior aesthetics of the floor surface, but also causes pedestrians to trip over computers and automation equipment. There were problems with the installation and stability of equipment such as equipment.

のである。Incidentally, the cause of the difference in level between the adjacent edges 21 of the floor panels C, which are placed on the panel support plate b1 of the support leg B and laid adjacent to each other, is due to the concrete foundation floor surface D of the building. It is extremely difficult to construct on a flat surface with no slope or unevenness, and the upper surface of the panel support plate b1 of each adjacent support leg B that is installed upright at intervals of the size (side width) of the floor panel C. This is said to be caused by the fact that the level varies depending on the slight difference in height of the foundation floor D, such as the slope and unevenness. In other words, if it is assumed that the floor surface part where the other support leg B is erected is lower than the floor surface part where the other support leg B is erected adjacent to each other at the side width interval of the floor panel C, both support legs The floor panel C, which is laid in a bridge-like manner across the spaces B, is laid in a manner that corresponds to the height difference due to the above-mentioned slope, unevenness, etc., which slopes from one side toward the other support leg B side. In this way, if the installation form of the floor panel C is different, 1
On the panel support plate b1 of the support leg B at the location,
The corner portion of one of the adjacent floor panels C is hooked on the peripheral edge of the flat panel support plate, and the mating edge 21 side of the floor panel C is floating, and the other floor panel C is in a floating state. A step is created between the mating edge 21 and the mating edge 21.

動による影響を与える虞れがあった。Furthermore, the floor panel C used in this type of double floor is generally constructed of a metal plate such as steel, but conventionally the floor panel C used in this type of double floor is constructed of a metal plate such as steel. Since the corner portion of panel C is directly mounted and supported, a contact sound (metallic sound) with the support plate b1, which is also made of a metal plate, may be generated, and vibrations caused by pedestrian walking may be generated on each support leg B. There was a possibility that the vibration would be transmitted to the installation floor surface of the installed equipment through the panel support plate b1 of the panel support plate b1, and the vibration would affect the installed equipment.

To provide a strong installation structure with excellent earthquake resistance, and to lay floor panels almost on the same surface with no steps, without being affected by slight differences in height such as the slope or unevenness of the foundation floor surface. In addition, the purpose is to prevent vibrations caused by pedestrians' walking from being transmitted to the installed equipment.

The upper surface level of the panel support plates of adjacent support legs differs due to slight differences in height such as slopes and unevenness, and as a result, even if the floor panel is laid in a bridge-like manner between both support legs, it may be tilted in one direction. All the corner parts are supported at the center of the upper surface of the panel support plate without a part of the corner part getting caught on the peripheral edge of the panel support plate. Therefore, the floor panels can be laid almost flush with no steps between the mating edges without being affected by slight differences in height of the base floor surface such as slopes and unevenness.

As a result, vibrations caused by the pedestrian's steps are absorbed and alleviated by the cushioning member, so there is no risk of the vibrations caused by walking affecting the installed equipment.
