Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] Please see Figure 1-5 This utility model provides a technical solution: a floor structure for a pharmaceutical factory, comprising: The floor structure base layer has a crack-resistant reinforcement layer 7 on its upper surface; The crack-resistant reinforcing layer 7 has a grounding structure 9 on its upper surface, the lower end of which is embedded in the bottom of the floor structure base layer; The grounding structure 9 has an anti-static wear-resistant layer 11 at its upper end; Expansion joints 8 are longitudinally provided in the base layer of the floor structure, the crack-resistant reinforcement layer 7, the upper end of the grounding structure 9, and the anti-static wear-resistant layer 11; A polyurethane sealing strip 10 is inserted into the expansion joint 8; The upper end of the grounding structure 9 is provided with a gap corresponding to the expansion joint 8, and copper braided strips 97 are welded between the gaps; Copper braided tape 97 transversely penetrates polyurethane sealing strip 10.

[0024] Specifically, in this embodiment, the base layer of the floor structure is the substrate of the floor structure, and the crack-resistant reinforcement layer 7, the upper end of the grounding structure 9 and the anti-static wear-resistant layer 11 are sequentially provided on this substrate; Furthermore, polyurethane sealing strips 10 are used to fill expansion joints 8 to prevent dust accumulation. The polyurethane sealing strips 10, which are in conjunction with the elastic body of expansion joints 8, compensate for the expansion and contraction of the floor structure base layer due to temperature differences, thereby reducing the risk of cracking of the floor structure base layer. More specifically, the crack-resistant reinforcement layer 7 strengthens the crack resistance of the surface layer through the reinforcement layer structure; the copper braided strip 97 connects the gap at the top of the grounding structure 9 caused by the opening of the expansion joint 8, ensuring the anti-static effect of the floor structure. Understandably, the antistatic wear-resistant layer 11 is made of wear-resistant and corrosion-resistant material, and has conductive properties. Together with the grounding structure 9, it conducts static electricity into the ground, thus playing an antistatic role.

[0025] In some embodiments, the polyurethane sealing strip 10 has a reserved window 96 corresponding to the copper braided strip 97; The copper braided strip 97 passes horizontally through the reserved window 96.

[0026] In some embodiments, the grounding structure 9 includes: A copper foil grid 91, the gaps of which are filled with a conductive primer 92; A ring-shaped conductive strip 93 is welded to the edge of the copper foil grid 91, and a conductive connecting rod 94 is vertically inserted through the ring-shaped conductive strip 93; The lowest longitudinal part of the floor structure base layer is pre-embedded with a grounding electrode 95, which is fixed to the lower end of the conductive connecting rod 94 by welding with multiple strands of copper wire.

[0027] Specifically, in this embodiment, the copper foil mesh 91 is a copper mesh, and both ends are welded to the annular conductive strip 93 by copper strips. The annular conductive strip 93 is specifically a copper annular strip. Furthermore, the annular electrostatic conductive strip 93 passes through the conductive connecting rod 94, which is used to electrically connect with the grounding electrode 95 through multi-strand copper wire to conduct static electricity to the ground. More specifically, the conductive primer 92 is an epoxy resin containing graphite powder, with a graphite powder content of 15%, forming a continuous conductive network to ensure the conductive connection between the copper foil grid 91 and the antistatic wear-resistant layer 11. It is understandable that conductive paste is applied to the welding intersections of the copper foil mesh 91, the welding intersections of the copper foil mesh 91 and the annular conductive strip 93, and the welding intersections of the multi-strand copper wire with the conductive connecting rod 94 and the grounding electrode 95 to ensure conductivity.

[0028] In some embodiments, the expansion joint 8 is specifically trapezoidal to reduce stress concentration. The sloping design of the trapezoid can gradually disperse the stress generated by structural deformation, such as thermal expansion and contraction and load action, avoid stress concentration at right angles or sharp corners, and reduce the risk of cracking. It can also accommodate multi-directional displacement. The sloping side of the trapezoid allows the structure to have a certain displacement space in the horizontal and vertical directions.

[0029] In some embodiments, the crack-resistant reinforcing layer 7 includes: The first epoxy resin layer 71 has a first glass fiber mesh 72 on its top surface. The first glass fiber mesh 72 is cured on the upper end of the first epoxy resin layer 71. The crack resistance of the crack-resistant reinforcing layer 7 is enhanced by the material properties of the glass fiber mesh, thereby improving the structural strength.

[0030] In some embodiments, a second epoxy resin layer 73 is provided on the upper surface of the first glass fiber mesh 72; The top surface of the second epoxy resin layer 73 is provided with a second glass fiber mesh 74. The first glass fiber mesh 72, the second epoxy resin layer 73, and the second glass fiber mesh 74 are cured layer by layer, and an additional epoxy resin layer and glass fiber mesh are added to further improve the crack resistance and strength of the floor structure.

[0031] In some embodiments, the antistatic and wear-resistant layer 11 is specifically a polyurethane mortar layer incorporating carbon nanotubes.

[0032] Specifically, in this embodiment, an appropriate doping ratio is selected based on the diameter and length of the carbon nanotubes to give the polyurethane mortar layer a good antistatic effect. This ratio can be obtained through limited experiments. Understandably, carbon nanotubes are incorporated into the polyurethane mortar layer and then vigorously stirred to ensure their uniform distribution.

[0033] In some embodiments, the polyurethane sealing strip 10 and the antistatic wear-resistant layer 11 are made of the same material, which is a polyurethane mortar layer incorporating carbon nanotubes. It has elasticity and conductivity, and is filled in the expansion joint 8 to hide the expansion joint 8, achieve an aesthetic effect, and prevent dust accumulation in the expansion joint 8. Furthermore, the polyurethane sealing strip 10 can deform with the expansion and contraction of the expansion joint 8 and can play an auxiliary conductive role. The copper foil mesh 91 and the conductive primer 92 are connected to the gaps in the expansion joint 8. The main conductive connection is still achieved through the copper braided strip 97, which hangs down in the middle in an arc shape in its normal state.

[0034] In some embodiments, the subfloor structure includes: A compacted soil layer 1 is provided on top of a concrete cushion layer 2. A concrete structural layer 3 is provided on the upper end of the concrete foundation layer 2; A slope-finding layer 4 is provided on the upper end of the concrete structural layer 3, and a foamed cement layer 5 is provided on the upper end of the concrete structural layer 3. The above structure is a common basic structural layer of the floor, and the thickness is set according to the construction requirements. This is an application of existing technology.

[0035] In some embodiments, the foamed cement layer 5 is provided with a retaining edge, and the upper surface of the foamed cement layer 5 is provided with a concrete bonding layer 6. The crack-resistant reinforcing layer 7 is located on the upper end of the concrete bonding layer 6; The edge of the foamed cement layer 5 is wrapped around the outside of the crack-resistant reinforcing layer 7 and the antistatic wear-resistant layer 11. The edge of the foamed cement layer 5 extends and covers the sidewalls of the crack-resistant reinforcing layer 7 and the antistatic wear-resistant layer 11, thus providing a waterproof function.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
