[0034] The following will be combined with the attached Figure 1-3 An anti-static non-pyrophoric floor of the present application is further described in detail.

[0035] An anti-static non-pyrophoric floor, the floor comprises from bottom to top a base layer 1, a cushion layer, an anti-seepage layer 5, a conductive layer 6, and a non-pyrophoric mortar layer 8;

[0036] The cushion layer includes a crushed stone cushion layer 2 and a concrete cushion layer 3 from bottom to top;

[0037] The impermeable layer 5 is cast with impermeable concrete and equipped with a steel frame;

[0038] Conductive aggregate is spread on the upper surface of the conductive layer 6 , and a flat steel conductive mesh 10 is laid in the conductive layer 6 ; the flat steel conductive mesh 10 penetrates the conductive layer 6 from top to bottom.

[0039] In a specific embodiment of the present application, the base layer 1 is a plain soil layer, which is compacted mechanically or manually to improve the density and bearing capacity of the base layer 1. Laying a cushion layer on the base layer 1 can further increase the bearing capacity and stability of the foundation, wherein the cushion layer using a crushed stone cushion layer 2 can also protect the overlying floor structure from erosion by the underlying strata. The main materials of the non-fireproof mortar layer 8 are dolomite, inorganic non-metallic aggregates, etc., which are wear-resistant and can withstand impact without sparking. At the same time, due to the existing anti-static non-fireproof floor, conductive aggregates are often spread on the top layer of the floor structure, which is prone to rust during use and can cause scratch damage to rubber tires. Adding a non-fireproof mortar layer 8 on the conductive layer 6 can increase the service life of the floor and also protect mechanical equipment. The function of the anti-seepage layer 5 is to be waterproof, dustproof, and chemically resistant to avoid affecting the stability of the underlying structure.

[0040] In the specific embodiment of the present application, the flat steel conductive mesh 10 is formed by hot-melt welding of flat steel along the conductive layer 6 in the horizontal and vertical directions, and has good conductive properties and mechanical strength. The flat steel conductive mesh 10 is arranged to penetrate the conductive layer 6 from top to bottom. On the one hand, it can cooperate with the conductive aggregate and be connected to the pre-buried grounding terminal to conduct static electricity to avoid the generation of static sparks and meet the anti-static requirements of the floor; on the other hand, it can also cooperate with the steel skeleton of the anti-seepage layer 5 to jointly improve the compressive strength and tensile strength of the floor and avoid floor collapse and cracking.

[0041] An impermeable membrane 4 is laid between the impermeable layer 5 and the cushion layer.

[0042] In the specific embodiment of the present application, the anti-seepage membrane 4 is a polyethylene geomembrane, which has high rigidity and toughness, good mechanical strength, good resistance to environmental stress cracking and tearing strength, and can resist corrosion by acids, alkalis, organic solvents, etc., and is suitable for use in areas with poor geology or relatively deep cushions. By laying the anti-seepage membrane 4 between the anti-seepage layer 5 and the cushion layer as the last line of defense to prevent liquid infiltration, the tensile strength of the floor structure can be improved and cracking can be reduced.

[0043] A waterproof coating 9 is applied between the anti-seepage layer 5 and the conductive layer 6 .

[0044] In a specific embodiment of the present application, the waterproof coating 9 is two 1.5 mm thick polyurethane coatings, which are the first line of defense to prevent liquid from seeping in. The construction is convenient and can reduce construction costs.

[0045] A plain cement slurry bonding layer 7 is also provided between the waterproof coating 9 and the anti-seepage layer 5 .

[0046] In a specific embodiment of the present application, the thickness of the plain cement slurry bonding layer 7 is 20 mm, which is used to increase the connection strength between the anti-seepage layer 5 and the overlying structure.

[0047] The conductive aggregate includes a first conductive aggregate 12 and a second conductive aggregate 11;

[0048] The particle size of the first conductive aggregate 12 is greater than the particle size of the second conductive aggregate 11;

[0049] The first conductive aggregate 12 is evenly spread on the surface of the conductive layer 6;

[0050] The second conductive aggregate 11 is evenly spread among the first conductive aggregates 12 .

[0051] In a specific embodiment of the present application, when the concrete of the conductive layer 6 is initially set, a layer of conductive aggregate 2-3 mm thick is spread on its upper surface. Specifically, a first conductive aggregate 12 with a relatively large particle size is first spread as a skeleton, and then a layer of a second conductive aggregate 11 with a relatively small particle size is spread to fill the gaps between the first conductive aggregates 12 to improve the uniformity and dispersion of the conductive aggregate spreading and ensure the conductive performance of the conductive aggregate.

[0052] The conductive aggregate is NFJ type metal aggregate, which is a hard metal honeycomb particle with anti-static, non-inflammable and corrosion-resistant properties.

[0053] The conductive layer 6 has a thickness of 50 mm; the flat steel conductive mesh 10 has a height of 50 mm and a thickness of 4 mm.

[0054] The thickness of the crushed stone cushion layer 2 is 150 mm, the thickness of the concrete cushion layer 3 is 100 mm, the thickness of the anti-seepage layer 5 is 150 mm, and the thickness of the non-refractory mortar layer 8 is 10 mm.

[0055] The concrete cushion layer 3 adopts C15 concrete, the anti-seepage layer 5 adopts C20 anti-seepage concrete, and the conductive layer 6 adopts C30 fine stone concrete.

[0056] The steel skeleton is φ6@200 double-layer bidirectional steel mesh.

[0057] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
