NICHIAS PAD FLOOR™

Concrete-based (GRC) raised access floor

TOMBO™ No. 6470

Nichias’ Pad Floor are durable, high-strength raised-access floor system panels that take the attributes of concrete, which cracks easily on its own, and combines it with GRC (Glass fiber Reinforced Cement) and specially processed steel plates. It has superior walking comfort and creates a comfortable office environment.

Forte

A high-strength panel made of GRC (Glass fiber Reinforced Cement) reinforced with a steel plate
While concrete on its own has a characteristic of being easily cracked, by combining GRC with specially processed steel plates, a sturdy, high-strength concrete panel is made. This allows for stable walking equivalent to that of floor slabs.
Superior walking comfort without rattling sounds.
A two-tiered protrusion rubber gasket is adopted to reduce creaking and hollow sounds, and absorb the rattling sounds which was a drawback of the raised access floor system. A characteristic of this is that walking becomes natural and gentle, which reduces the burden on the feet of office workers.

A raised access floor system which boasts excellent cost performance.
Offers various superior properties at low cost. Contributing to office environment creation with economic efficiency in mind.

Note 1: When a pedestal with a finish height of 100 mm is used.
Note 2: This is a design specification number and unevenness must be considered when actually installing. This number includes the surface material thickness of 6.5 mm.
*The thickness and system weight numbers do not include the surface material.
*Nichias also offers pedestals that have undergone whisker treatment. Please contact us if you are interested in this product.
*For information on the precautions, please refer to each individual catalog.

Pedestal

Performance Test

Support the panel on 4 φ80 steel pedestals, and apply a φ50 load using a load tester.

Concentrated Load Performance (standard value)

Concentrated Load Performance	0 type/PK type
Concentrated Load Performance	Panel center	Center of the sides
Maximum load (N)	9, 000 or more	4, 500 or more
Deflection at 3000 N (mm)	2.0 or less	3.0 or less

Rolling Load Test
A urethane-covered caster loaded with a realistic load is rolled along the center of the panel.

Rolling load performance (standard value)

Load (N)	Times rolled (count)	Damage and scratches
1000	10, 000	None

Impact Test
A center concentrated load test is conducted on a panel supported by four φ80 pedestals after a 30 kg sandbag (base φ220 JIS A 1414) is dropped by free fall to the center of the panel.

Impact Test (measurement organization: Nichias)

Drop height (cm)	Max. load (kN)	Deflection (mm)
50	9 or more	4.0 or less (3kN)

Leakage Resistance Test
Measures the leakage resistance.

Leakage resistance value (measurement organization: Nichias)

Panels	Leakage resistance (Ω)
No surface finishing materials	1×10⁵ to 2×10¹⁰

Seismic Resistance Test
Set the specimen onto the test machine, place the designated weight on the machine and apply a sinusoidal vibration at 2 Hz 3 waves 1.0 G maximum.
Observe the state of the specimen and check for deformation in the specimen. One side of the specimen shall be fixed to the wall.
*The specifications of the pedestal vary with the movable load.

Prohibitions and precautions

Prohibitions
Do not use for applications other than the raised access floor system.
Since strength decreases, do not install the panel upside down.
Do not modify the panels and pedestals on your own judgment as this may reduce their strength, which has the danger of the panel being destroyed and falling through. (Be sure to contact us.)
Do not place or move equipment that exceed the allowable concentrated load on the floor.
Do not leave the panels for more than 6 months without applying surface finishing materials.
Do not carry panels while holding them with the panel lifter.

Product usage precautions
Installation precautions
If installing or moving a machined panel, it will require reinforcement. Please contact us in such circumstances.
Be sure to cover panel openings with the dedicated cover lid.
The raised access floor system has a hole for accessing the power outlet. Accordingly, the joints of the carpet should be staggered by 70 mm or more from the joints of the floor.
An unpleasant smell may be generated by the reaction between the plasticizing agent on the back of the carpet and the alkaline water contained in the panel. Ventilate the area sufficiently after laying down the carpet.
NICHIAS recommends applying 30 to 60 g/m²of carpet bond (peel-up type adhesive). Follow the construction specifications of each manufacturer. Also, take care not to apply too much carpet bond when laying out the tile carpet as it may result in tile carpet damage due to excessive viscosity.
Store the panel and auxiliary materials in a place where it will not be subject to water.
When discarding a single panel, please treat it as glass scrap, concrete scrap, and ceramic scrap of general industrial waste.

Precautions for use
If the contact area with the floor is small when installing heavy objects such as bookshelves, the panel may be subject to an uneven load and this may cause deformation or damage. Therefore, install steel plates on the contact surface to distribute the load. (Gently install without applying any shocks.)
If installing equipment that is repeatedly subject to loads or vibrations such as mobile racks and large rotary presses, mount them on a frame directly on the concrete slab, and isolate it from the panel.
Equipment which may fall over should be fixed to the concrete slab or a durable wall and not fixed to the panel or pedestals.
Dropping heavy objects or applying excessive impact to the floor may have a risk of the panels being damaged and falling through. If working on top of panels that may be in such condition, check each time for any abnormalities and replace with new panels as necessary.
If moving heavy objects such as equipment, cover the parts subjected to loads with plywood or the like.
Do not remove panels unless it is necessary. When removing panels is unavoidable, take care to avoid accidents such as stumbling or falling over.
When cleaning, take care not to wet the wiring equipment etc.
Please contact us if you have any questions.
