pave anti-static floor and raised floor, which mainly has the following functions: 1.
I.
The other end of the grounding wire should be connected to a grounding column.
There should be no gap between adjacent floors, and the lower part of the floor where heavy equipment is installed should be strengthened.
7.
The construction process diagram of the anti-static floor on the ground is as follows: the construction process diagram of the machine room’s skirting steps is as follows: the skirting platform entering the machine room’s elevated ground should be waterproof and moisture-proof, beautiful and atmospheric, solid and practical.
③ if there is no control cabinet and other equipment on the indoor ground (when holes need to be left), the laying direction and sequence should be comprehensively considered.
The grounding column should preferably be buried at a depth of 50cm below the ground, so that the floor can play the role of static electricity release! Combined with the design and construction of wiring system, strong and weak current wiring trunking and grounding copper bar are installed overhead on the ground, and the spacing between strong and weak current wiring trunking is greater than 30mm.
The width of the step is 300mm, which is made of plain concrete.
Install angle steel support on the wall around the machine room, and lay metal shielding net (50*0.1 copper sheet) on the ground according to the ground snap line.
3、 Anti static floor laying diagram for the detailed installation of static floor has always been a difficult point for many friends, and they ask a lot of questions.
The space under the floor can be used as the static pressure air reservoir of the air conditioner to obtain satisfactory air distribution; 4.
④ determine the laying height according to the design requirements.
The insulation cotton is laid on the ground and the walls around the floor are laid with 25mm thick Armstrong grade I fule insulation cotton, wrapped with fule non combustible aluminum foil, which plays the role of heat preservation, heat insulation and moisture resistance.
Eliminate the harm of cable exposure to human body; 5.
When laying the floor, level it gradually with a bubble level, and the height is adjusted by an adjustable support.
The metal shielding net is connected with the grounding copper bar of the machine room to form a complete machine room shielding system, which has the functions of grounding, anti-static and anti-interference.
Ground treatment: in the installation of anti-static floor of the machine room, the ground pretreatment is very critical.
So far, the ground pretreatment is completed.
Based on the above, after the laying method is determined, it is necessary to carry out centering, square setting, grid division, positioning and setting out, that is, the grid division line needs to be marked on the ground, and the elevation line needs to be marked on the surrounding walls, so as to facilitate the operation control during construction.
1.
The adjustability of the anti-static raised floor can be used to eliminate the unevenness of the ground and ensure the overall levelness of the machine room floor; 6.
Lay the movable floor slab and adjust the horizontal height to ensure that the four corners contact smoothly and tightly.
We can see this at a glance.
In this project, 120mm brick walls can be used to isolate the machine room’s elevated ground, and a step is set.
The floor elevation is 300~350mm, and there is enough space to form a net pressure air reservoir under the floor.
If the movable floor slab does not meet the modulus, the insufficient part can be cut and patched according to the actual size (it should be fine when cutting the floor), and equipped with corresponding adjustable supports and beams.
Therefore, the equipment in the machine room can be connected freely under the anti-static floor, which is convenient for laying and maintenance, and makes the machine room neat and beautiful; 2.

If the difference is not obvious, it should be laid from the outside to the inside; If the difference is large, it is advisable to conduct symmetrical division and lay from inside to outside.
According to the flat size of the room and the layout of the equipment, the laying scheme and reasonable laying method shall be formulated according to the module of the movable floor, and the following principles shall be followed: ① if there is no control cabinet and other equipment in the room, the geometric dimension should be laid from the inside to the outside when it meets the module of the movable floor.
In order to facilitate everyone to understand, we have some diagrams here for you to understand more intuitively.
Lay anti-static floor and install the floor support feet directly above the 50*0.1 copper sheet.
First, brush a layer of plain mud, smooth the machine room floor, use 20 thick 1:2.5 cement sand plaster to polish, and the ground foundation must be treated to be flat Smooth, without obvious slope and unevenness, and then brush the special floor paint of the machine room twice to prevent moisture and mildew.
2.
1、 The function of electrostatic floor the machine room floor generally adopts anti-static raised floor.
It can make electrostatic charge leak to the ground and reflect electromagnetic radiation.
4.
② if the indoor plane size does not conform to the plate modulus, find out the center points of the two directions indoors to see how much the size difference between the two sides is.
The snapping line should be corrected repeatedly.
The function of the anti-static floor is to introduce the static electricity generated on the ground to the earth through the anti-static floor.
It can protect all kinds of cables, wires, data lines and sockets from damage; 3.
II.
Before laying the floor, the ground must be well pretreated.
5.
Secondly, when the copper bars are laid to the wall, collect several points and connect them to the grounding wire (three to five points are the best to prevent a little disconnection in use).
Detachability.
According to the actual needs, waterproof materials are laid on the surface of the step, Such as marble, T-shaped steel plate, plastic floor, etc.
3.
The floor of the machine room should comply with the national standard gb6650-86 “technical conditions of raised floor for computer room”.
Draw a horizontal line and snap a square grid line on the ground.
Construction requirements for the installation of electrostatic floor.
The grounding copper bar should first lay a layer of copper bars under the floor for full contact with the floor.
