Description

Concrete false floor with antistatic feature

The utility model relates to a kind of concrete antistatic raised floor, belongs to the flooring laying member class that the building fitting-out work is used.

Chinese patent CN2050057U discloses a kind of " antistatic cement movable floor ", comprises substrate, packed layer and top plane layer.Substrate adopts the fibrous composite based on cement, and the top plane layer is a terrazzo concrete, and the packed layer between substrate and the top plane layer adopts lightweight aggregate.The weak point of this movable floor is that electric conductivity is relatively poor, and structural strength is lower.

The purpose of this utility model is to provide the concrete that a kind of electric conductivity is good and structural strength is higher antistatic raised floor, is applicable to that the ground of computer room or other machine room is laid.

The purpose of this utility model reaches as follows: a kind of concrete antistatic raised floor, comprise the substrate of making by concrete, and reinforcing bar is set in substrate, on substrate top surface, adhere to one deck veneer, veneer adopts conductive rubber or conductive plastics to make.The side is stained with flange around substrate, and flange adopts engineering plastics to make.For the substrate that concrete is made has enough electric conductivity, in this concrete material, mixed the flyash that accounts for gross weight 10～20%, utilize the permanent conduction of unburnt carbon granules realization concrete material in the flyash.

The purpose of this utility model can also reach in the following way: in substrate laid inside steel-wire screen, not only can improve the compressive strength of substrate, also help to improve substrate conducting, reduce bulk resistor.

On the bottom surface of substrate, can apply one deck aluminium paint, can prevent the base plate bottom exposed surface dirt that looses, and reduce the contact resistance between itself and the movable floor rack, improve electric conductivity.

Side around substrate can tilt from top to bottom slightly inwards, and it is 5～15 ° with the angle of vertical plane, closely contacts when laying with the end face that guarantees each block concrete antistatic raised floor, does not stay the slit, and can be to construct and provide convenience.

The advantage of the utility model comparison prior art is:

1. structural strength is higher, and reinforcing bar and steel-wire screen are set in concrete substrate, guarantees that goods have enough intensity.

2. conduct electricity very well, can guarantee that static releases by movable floor rack.

3. long service life.

The drawing of accompanying drawing is described as follows:

Fig. 1 is the structure sectional view of a kind of embodiment of the present utility model.

Fig. 2 is the vertical view of the foregoing description.

The utility model will be further described as follows in conjunction with the accompanying drawings: see figures.1.and.2.

A kind of concrete antistatic raised floor, comprise substrate (1), veneer (3), flange (4), substrate (1) adopts concrete material to make, and reinforcing bar (2) and steel-wire screen (5) have been disposed at concrete, in concrete, also mixed the flyash that accounts for gross weight 18%, thereby make substrate (1) both have enough mechanical strengths, have good electrical conductivity again, be beneficial to electrostatic leakage.Veneer (3) adopts the conductive polyvinyl chloride plastics to make, and flange (4) adopts igelite to make.Apply one deck aluminium paint in substrate (1) bottom surface, proportioning is a silver powder: varnish=1:10.Substrate (1) slopes inwardly the side all around from the top down slightly, with the angle of vertical plane be 8 °.After tested, the surface resistivity of above-mentioned concrete antistatic raised floor is 10 ⁶Europe, body resistivity are 10 ⁷Europe has good electrostatic leakage ability, and has intensity height, not yielding, good, fire-retardant, the long service life of walking texture, low cost and other advantages, meets standard GB 6650-86 " computer room movable floor technical condition ".
