The legs of the floorboard loaded on the leg base are supported by the rounded corners of the leg base and frame projections, so even after inserting four legs, the floor plate can be adjusted slightly if the floor plate is lifted slightly. Because of the flexibility, the construction speed can be increased. The legs of the floorboard are not fixed to the legs, so if there is a slight inclination or step on the ground, the legs themselves will bend in shallow grooves, but the legs will also tilt accordingly and respond accordingly. it can. The floorboards meet the requirements for weight reduction and strength. As a double floor of this type, it is the lightest and has a strength of 3 floors.
The center deflection at the load of 00kg does not become 2mm.
Extremely durable. The leg is provided with small holes useful for drainage and binding. It can be tied together, so it is convenient for construction without scattering.In addition, the stoma holes are condensed in the leg seat and water is accumulated, even when water is spilled. . The floorboards mounted on the leg seats are independent of each other, so vibration and walking sound are not transmitted, and the legs can respond to inclination, so distortion and steps on the ground are eliminated only at that part, affecting the whole do not do. The level difference of the base can be adjusted with the vibration-absorbing rubber pad. When a shock absorbing rubber pad or a shock absorbing spacer is installed, it functions as a so-called seismic isolation double floor.
