[0039] One embodiment of the present application provides a fireproof and heat-insulating cotton outer protection system for a fixed drilling platform, hereinafter referred to as the fireproof and heat-insulating cotton outer protection system. Figure 1 and Figure 2 The fireproof heat-insulating wool outer protection system comprises a deck 10, a floating floor structure 20, an interface agent layer (not shown in the figure) and a tile layer 30. The floating floor structure 20 comprises a first fireproof heat-insulating wool layer 21, a metal wire mesh layer 22 and a deck covering layer 23.

[0040] The deck 10 has an upper surface 11, and the upper surface 11 has a chamber area for building a chamber. A first fireproof and heat-insulating wool layer 21 is laid in the chamber area. Exemplarily, the material of the first fireproof and heat-insulating wool layer 21 can be rock wool.

[0041] The metal mesh layer 22 is laid on the end face of the first fireproof and heat-insulating cotton layer 21 away from the upper surface 11. Exemplarily, the metal mesh layer 22 can be a steel mesh layer. Exemplarily, the specification of the metal mesh is: Ф5*150*150mm. The deck covering layer 23 is arranged to cover the metal mesh layer 22. Exemplarily, the components of the deck covering layer 23 can include AC-JIII type self-leveling deck covering and water. The mixing weight ratio of AC-JIII type self-leveling deck covering and clean water is: 1: (0.17-0.19). The interface agent layer is arranged on the end face of the deck covering layer 23 away from the metal mesh layer 22. The tile layer 30 is laid on the end face of the interface agent layer away from the deck covering layer 23. Exemplarily, the components of the interface agent layer can include at least one of putty powder, mortar or glue. Exemplarily, the tile layer 30 can use anti-slip tiles to further improve the anti-slip property.

[0042] The specific construction steps include: Step 1: Before the project construction, clean the room, clean the floor, polish the floor, and apply primer to the room floor. Step 2: Prepare the construction area by hoisting each layer of materials. Step 3: Lay and install the first fireproof and thermal insulation cotton layer 21 and check the effect. Step 4: Lay the metal mesh layer 22 on the first fireproof and thermal insulation cotton layer 21. Step 5: Cut the self-leveling deck dressing, use a mixer to stir the AC-JIII type deck dressing and water, and pour the dressing on the metal mesh layer 22 after stirring. After the dressing is leveled, use tools (defoaming roller, scraper) to remove bubbles and control the flatness. Step 6: After the deck dressing is constructed for 12 hours, use a small roller to evenly apply a layer of interface agent. The weight ratio of the interface agent to water is 1:5. After the interface agent is cured, use a small roller to evenly apply a layer of interface agent. The weight ratio of the interface agent to water is 1:3. Step 7: Laying, leveling, caulking and inspection of tile layer 30.

[0043] In the present application, the fireproof and heat-insulating properties of the deck 10 corresponding to the chamber area are achieved through the coordinated cooperation of the first fireproof and heat-insulating cotton layer 21, the metal mesh layer 22, the deck dressing layer 23, the interface agent layer and the ceramic tile layer 30. In addition, the above-mentioned structure is arranged in the chamber area, so that the above-mentioned structure can be repaired indoors, thereby helping to reduce the interference of environmental factors and thus helping to reduce the difficulty of maintenance. In addition, the first fireproof and heat-insulating cotton layer 21 can be effectively and stably protected through the coordinated cooperation of the metal mesh layer 22, the deck dressing layer 23, the interface agent layer and the ceramic tile layer 30, which helps to simplify the system structure and thus help to reduce the construction cost. In addition, the use of the ceramic tile layer 30 as the outer layer helps to reduce system wear and tear, which also helps to reduce costs.

[0044] In some embodiments, the number of first fireproof thermal insulation cotton layers 21 is at least two (two first fireproof thermal insulation cotton layers 21 are shown in the figure), and the two adjacent first fireproof thermal insulation cotton layers 21 are staggered and spliced, so as to increase the heat dissipation path to improve the thermal insulation effect. In addition, the staggered splicing is also beneficial to improve the support stability of the system in the plane, thereby also helping to increase the service life of the system to further help reduce the cost of use.

[0045] In some embodiments, the wire mesh layer 22 includes wires and a plurality of wire meshes, two adjacent wire meshes are overlapped, and the wires are used to bind the two adjacent wire meshes. The structure of the wire mesh layer 22 is convenient for construction and helps ensure the connection stability of the wire mesh layer 22.

[0046] In some embodiments, the overlap distance between two adjacent metal meshes is 15-20 cm, and the mesh distance between the metal meshes is 15-20 cm. The size of the mesh has the advantages of improving connection stability and reducing the amount of dressing to reduce costs.

[0047] In some embodiments, the deck covering layer 23 protrudes from the wire mesh layer 22 by at least 20 mm.

[0048] In some embodiments, reference Figure 3 , the fireproof and thermal insulation cotton outer protection system also includes a fire wall structure 40.

Exemplarily, the second fireproof and thermal insulation cotton layer 41 can be fixed by insulation nails and a pressure cover. Exemplarily, the second fireproof and thermal insulation cotton layer 41 can be a rock wool layer. The construction of the fire wall structure is conducive to improving stability and wind resistance. And the structure of the fire wall structure is simple to help reduce construction costs.

[0049] In some embodiments, the second fireproof heat-insulating cotton layer 41 is attached to the raised area of ​​the corrugated wall 42 .

[0050] In some embodiments, reference Figure 4 -5, the deck 10 has a lower surface 12 that is set away from the upper surface 11, and the fireproof thermal insulation cotton outer protection system also includes a third fireproof thermal insulation cotton layer (not shown in the figure), a plurality of laid support columns 50, a lining frame 60 and at least two metal plates 70. The third fireproof thermal insulation cotton layer is attached to the lower surface 12, and the projection of the third fireproof thermal insulation cotton layer on the deck 10 is located outside the chamber area. Exemplarily, the third fireproof thermal insulation cotton layer can be a rock wool layer. Exemplarily, the third fireproof thermal insulation cotton layer can be fixed by insulation nails and pressure covers. The gap near the third fireproof thermal insulation cotton layer can be taped with aluminum foil tape. Each support column 50 is protrudingly installed on the lower surface 12 and is set through the third fireproof thermal insulation cotton layer. Exemplarily, the support column 50 can be an angle steel structure. The lining frame 60 is fixed to one end of the support column 50 away from the lower surface 12. The metal plate 70 is installed on the lining frame 60, and two adjacent metal plates 70 are overlapped. Two rivets 61 are laid at the overlap of the metal plates 70 to connect the metal plate 70 and the lining frame 60. For example, the metal plate 70 can be a stainless steel plate. The use of double-row rivets 61 reinforcement in conjunction with the third fireproof insulation cotton layer, the support column 50, the lining frame 60 and the metal plate 70 is conducive to improving the structural strength, thereby improving the wind resistance and reliability.

[0051] In some embodiments, a single rivet 61 is used at the non-overlapping portion of the metal plate 70 to connect the metal plate 70 and the lining frame 60 , thereby helping to reduce costs.

[0052] In some embodiments, a glue layer is provided at the gap between two adjacent metal plates 70 and the gap between the metal plate 70 and the lining frame 60 for sealing.

[0053] In some embodiments, the overlapping distance between two adjacent metal plates 70 is greater than or equal to 20 mm, thereby facilitating improving the connection strength between different metal plates 70 .

[0054] In some embodiments, the interface agent layer includes a first layer and a second layer, the first layer is attached to the deck covering layer 23, and the weight ratio of the interface agent to water in the first layer is 1:5. The second layer is attached between the first layer and the tile layer 30. In the second layer, the weight ratio of the interface agent to water is 1:3.
