Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of AGV floor, and in particular to a floor system and a construction method. Background Art
[0002] Large single-unit steel structure workshops are used to meet the needs of large-scale, high-efficiency centralized production. Such workshops usually have the characteristics of large single-unit area, large span, and significant flexibility (i.e., the deformation of the structure under load). In such a complex structural environment, the choice of floor finishes is not only related to the cleanliness and aesthetics of the production environment, but also directly affects the production efficiency and the stability of equipment operation.
[0003] With the continuous advancement of automation technology, automated guided vehicles (AGVs) have become an important means to improve production efficiency and realize intelligent logistics. The extensive use of AGVs has also led to a significant increase in ground dynamic loads, especially in large-span, large-volume single crystal plants, where this impact is particularly significant.
[0004] During the operation of the AGV, the silicon particles or impurities attached to the tires, because of their higher hardness than the ground material, form a wear effect similar to that of a grinding wheel. Especially when the AGV turns on the spot, due to the increase in the instantaneous starting torque, the floor at the turning position suffers more serious wear. In the long run, it will cause the ground to sag, the AGV will deviate, and its navigation accuracy and stability will decrease, which will affect the normal operation of the AGV and even the stable operation of the entire production line.
[0005] At present, there are mainly the following types of floor finishing options in the new energy industry:
[0006] Diamond abrasive integrated floor: Inorganic floor, constructed simultaneously with concrete, prone to color difference, poor overall flatness, easy to crack and dust, AGV bumps too much during operation, easily causing damage to vehicles and products, and excessive maintenance costs;
[0007] Polyurethane floor: Organic floor, although easy to construct, has low hardness, poor wear resistance, and high maintenance cost. After half a year of operation, the AGV will wear through the surface layer, causing depressions, and further wear the base layer, causing damage to vehicles and products. The maintenance cost and repair frequency are too high.
[0008] Inorganic terrazzo floor: Inorganic terrazzo floor meets the requirements of high-cleanliness industrial plants with its seamless, dust-free and easy-to-clean characteristics. However, long-term exposure to heavy loads and friction caused by AGV operation will still cause wear and dirt problems, which will also cause damage to vehicles and products and affect the stable operation of production, resulting in excessive secondary maintenance costs.
[0009] Fully paved steel floor: Although it can theoretically provide excellent load-bearing and wear-resistant performance, the high cost and problems such as metal stress and warping that may occur during use limit its widespread application. Summary of the invention

Slots are set on the inorganic terrazzo floor layer on both sides of the top of the expansion joint, and the debris and filling wooden boards in the original joint are removed. Then, concrete piers are piled up in the slots with leveling mortar. The width of the concrete piers is adapted to the width of the slots.

When the waterstop on the upper layer is damaged or leaking, the waterstop on the lower layer can serve as a bottom to block the water again. And with the increase of use time, even if the waterstop on the lower layer is partially damaged and leaking in the later stage, due to the presence of the waterstop grille, the waterstop in other parts still has a water-blocking effect, and only the partially damaged positions will leak, reducing the leakage when both waterstops are damaged, and mitigating the damage to the floor.

[0067] S22. After the grouting material solidifies to a certain strength, the carbon fiber cloth is pasted to further reinforce the concrete base by utilizing the high strength and high modulus characteristics of the carbon fiber cloth;
[0068] S23. After the carbon fiber cloth is firmly bonded, a φ1.8mm finished steel wire mesh is spread on its surface. The steel wire mesh can effectively disperse stress and prevent the floor from cracking;
[0069] S3. pouring inorganic terrazzo material to form an inorganic terrazzo floor layer;
[0070] S4. Carry out expansion joint and AGV track construction;
[0071] Among them, the thickness of the inorganic terrazzo floor layer is 25mm, the aggregate is Kunshan stone, the aggregate particle size is required to be uniform and the particle size is about 10mm~15mm, the aggregate hardness is not less than Mohs 7, semi-matte treatment and secondary grading are performed;
[0072] The expansion joint construction is carried out on the original seam with a width of 2cm. The two sides of the original seam are cut and widened to 60mm and 55mm deep. Slots are set on the inorganic terrazzo floor layer on both sides of the top of the expansion joint. The depth of the two slots is 25mm and the width is 50mm. The debris and the filling wood in the original seam are removed, and then 11mm high concrete piers are piled in the slots with leveling mortar. The width of the concrete pier is adapted to the width of the slot. The base and water stop are installed on the concrete pier and fixed with expansion anchor bolts. A 5mm thick stainless steel slide is installed and structural glue is injected into the gap between the two sides of the slide and the base.
[0073] AGV track construction steps include:
[0074] Before step S3, according to the driving route and turning position of the AGV, the elevation is measured and the positioning is laid out, the concrete base is shot blasted, the line is drawn and the seams are cut, and then the two side panels as the support are installed.

Then, a guide rail and a steering wheel made of 8mm thick 304 stainless steel are installed. A 2mm thick XIKA 31CF high-strength adhesive is applied between the guide rail and the steering wheel and the cushion layer. During installation, the adhesive is squeezed out from the gap between the guide rail, the steering wheel and the side plate to ensure that there is no hollowing at the bottom of the guide rail and the steering wheel and there is no gap between the side plates. The excess adhesive is scraped off, and finally the guide rail and the steering wheel are reinforced with a second anchor bolt to achieve double insurance. The second anchor bolt is anchored downward into the cushion layer and the concrete base.

[0077] The track guide rails used by AGVs are made of stainless steel. The surface flatness of the rails can fully meet the requirements for smooth AGV travel and prevent the AGV from running off the track. The rails can be arranged along the AGV travel route. There is no need to lay steel plates on the floor. The AGV can run smoothly at a lower cost. The wear resistance of the rails is greatly improved compared to the floor. No maintenance is required, which saves a lot of floor maintenance costs.
[0078] The expansion joint body is widened, and the curved part of the original expansion joint can be cut off to make the expansion joint body straight. Slots are set on both sides of the expansion joint body, and the base and the slide are supported by the slots. When the AGV passes through the expansion joint body, the force-bearing area of the slide and the bottom of the base is increased, reducing the impact force on both sides of the expansion joint body, protecting the top of the expansion joint body, and avoiding damage to the floor around the expansion joint body;
[0079] The waterstop is set to two layers to improve the water-blocking effect and service life. When the waterstop on the upper layer is damaged or leaking, the waterstop on the lower layer can serve as a bottom to block the water again. And with the increase of use time, even if the waterstop on the lower layer is partially damaged and leaking in the later stage, due to the presence of the waterstop grille, the waterstop in other parts still has a water-blocking effect, and only the partially damaged positions will leak, reducing the leakage when both waterstops are damaged, and mitigating the damage to the floor.

Carry out expansion joint and AGV track construction; Among them, the AGV track construction steps include: Before step S3, the elevation is measured and the positioning is laid out according to the driving route and turning position of the AGV, the concrete base is shot blasted, the line is drawn and the seams are cut, and then the two side plates as the support are installed, the side plates on the same side are welded, and a plurality of first anchor bolts are set at the lower middle part of the side plates; During step S3, inorganic grindstone material is also poured between the two side plates. After hardening, the inorganic grindstone between the two side plates is removed, and then a cushion layer is piled up and leveled using solvent-free epoxy mortar at the bottom between the two side plates. Then, a guide rail and a steering wheel made of 304 stainless steel are installed. High-strength adhesive is applied between the guide rail and the steering wheel and the cushion layer. During installation, the adhesive is squeezed out from the gap between the guide rail, the steering wheel and the side plate to ensure that there is no hollowing at the bottom of the guide rail and the steering wheel and there is no gap between the side plates. Excess adhesive is scraped off, and finally the guide rail and the steering wheel are reinforced with a second anchor bolt, and the second anchor bolt is anchored downward into the cushion layer and the concrete base.
