[0039] Embodiment

[0040] Please combine Figure 1 and Figure 2 The present embodiment provides a profiled steel plate fireproof and waterproof composite wall, which comprises:

[0041] The profiled steel plate layer 100, the fireproof and heat insulation layer 200, the waterproof layer 300 and the outer protective layer 400 are arranged in sequence.

[0042] The profiled steel plate layer 100 is made of high-strength steel material through a profiling process, so that the profiled steel plate layer 100 forms a corrugated reinforcing structure, and the corrugated reinforcing structure has a plurality of first positioning grooves arranged at intervals in the width direction of the profiled steel plate layer 100; the fireproof and heat insulation layer 200 comprises opposite first and second plate surfaces, the first plate surface is formed with a plurality of first protrusions, and the plurality of first protrusions are respectively embedded in the plurality of first positioning grooves; a plurality of second protrusions are arranged on the second plate surface; the waterproof layer 300 is provided with a plurality of second positioning grooves on one side, and the plurality of second protrusions are respectively embedded in the plurality of second positioning grooves; and the outer protective layer 400 is adhesively fixed to the waterproof layer 300.

[0043] Based on the above scheme, the working principle of the profiled steel plate fireproof and waterproof composite wall provided by the present embodiment is as follows:

[0044] Through the combined use of the waterproof layer 300 and the fireproof layer, the waterproof and fireproof performance of the wall is improved. In actual application, the composite wall can effectively prevent water penetration and fire spread, providing strong guarantee for the safety and durability of the building structure.

[0045] It should be noted that the fireproof and heat insulation layer can be composed of fireproof paint, fireproof bricks or fireproof partitions and other fireproof materials. These materials all have excellent fire resistance and can prevent the spread of fire in the event of a fire. The fireproof and heat insulation layer can be coated on the surface of the profiled steel plate layer 100 or filled in the cavity inside the profiled steel plate layer 100. The fireproof paint coated on the surface can form a protective layer to slow down the direct ablation of the profiled steel plate by fire; and the fireproof material filled in the cavity can prevent the spread of fire and high-temperature gas.

[0046] In the event of a fire, the fire-resistant and fireproof layer can absorb a large amount of heat and reduce the temperature of the wall, thereby slowing down the spread of the fire and gaining more time for rescue work.

[0047] At the same time, the waterproof layer 300 can be made of materials such as asphalt, polyurethane paint, polymer waterproof paint, etc. The waterproof layer 300 can be evenly coated on the surface of the profiled steel sheet layer 100 to form a continuous waterproof film. This waterproof film can block the penetration of external moisture, ensuring the dryness and stability of the wall.

[0048] Further, at the edges, corners and lap joints of the profiled steel sheet, sealing paste, sealing glue and other sealing materials can be used for special treatment to enhance the waterproof performance of these key parts.

[0049] In long-term use, the waterproof layer 300 may be worn or damaged, so regular inspection and maintenance are needed to ensure its waterproof performance is durable and effective.

[0050] In addition, reinforcing bars, connectors, fixings and other auxiliary structures can be provided at the profiled steel sheet layer 100 and the connection position to enhance the overall stability and carrying capacity of the wall, ensuring its safety performance under various external actions.

[0051] In other embodiments, optional fireproof dust screen and other auxiliary fireproof measures can be used in combination with the fireproof layer to further improve the fireproof performance of the wall and reduce harmful substances generated during fire combustion.

[0052] It should be understood that when setting the fireproof and heat insulation layer and the waterproof layer 300, the cleanliness of the surface of the profiled steel sheet layer 100 needs to be ensured to improve the bonding stability and reliability.

[0053] The following embodiments illustrate the details of the profiled steel sheet fireproof and waterproof composite wall provided by the present application by way of example.

[0054] In this embodiment, the first positioning groove has a first groove wall and a second groove wall in the width direction of the profiled steel sheet layer 100, and at least one of the first groove wall and the second groove wall is provided with a concave-convex part 110, and the fireproof and heat insulation layer 200 is engaged with the concave-convex part 110.

[0055] In this way, by providing the concave-convex part 110 on the side of the profiled steel sheet layer 100, when the fireproof and heat insulation layer 200 is embedded in the first positioning groove, the fireproof and heat insulation layer 200 not only realizes the concave-convex structure cooperation with the first positioning groove, but also realizes the concave-convex structure cooperation with the concave-convex part 110. In this way, the profiled steel sheet layer 100 and the fireproof and heat insulation layer 200 are firmly combined and have a long service life.

[0056] For example, in this embodiment, the concave-convex part 110 can be arranged on both sides of the profiled steel sheet layer 100, thereby improving the bonding strength.

[0057] In this embodiment, the concave-convex part 110 can be arranged in a wave shape or a polyline shape.

[0058] It should be understood that the structure of the concave-convex part 110 is various and can be selected as needed. The concave-convex part 110 can be processed flexibly and conveniently, has low processing cost, and has a wide range of adaptation.

[0059] In this embodiment, the profiled steel sheet layer 100 has a first side and a second side in the width direction, one of the first side and the second side is provided with the clamping convex part 120, and the other of the first side and the second side is provided with the clamping concave part 130. The first side and the second side of the adjacent profiled steel sheet are clamped and matched through the clamping convex part 120 and the clamping concave part 130.

[0060] In this way, when the wallboard is installed, a plurality of wallboards are sequentially spliced, the first side and the second side of the adjacent wallboards are matched, the first side and the second side are matched with each other, that is, the clamping convex part 120 and the clamping concave part 130 are matched, so that the clamping is more firm when the adjacent wallboards are matched, and the service life is long.

[0061] In this embodiment, a waterproof film is arranged between the profiled steel sheet layer 100 and the fireproof and heat insulation layer 200.

[0062] By arranging the waterproof film, the waterproof effect is further improved.

[0063] In this embodiment, the fireproof and heat insulation layer is provided with a plurality of staggered drainage channels 210. Part of the plurality of drainage channels 210 extends in a first direction, and another part of the plurality of drainage channels 210 extends in a second direction having an included angle with the first direction. The drainage channel 210 extending in the first direction is in communication with at least one drainage channel 210 extending in the second direction.

[0064] During use of the composite wall, when it rains, part of the rainwater can enter the fireproof and heat insulation layer and collect in the drainage channel 210. When the amount of rainwater is large, the rainwater will be discharged along the drainage channel 210, and the drainage is convenient.

[0065] It should be understood that the number of drainage channels 210 is set as required, part of the drainage channels 210 extends vertically, and the plurality of vertically extending drainage channels 210 are arranged in the width direction of the profiled steel sheet layer 100. Part of the drainage channels 210 extends horizontally, and the plurality of horizontally extending drainage channels 210 are arranged in the height direction of the profiled steel sheet layer 100, and the two ends of the horizontally extending drainage channels 210 are in communication with the outermost two of the vertically extending drainage channels 210. In this way, the horizontal drainage channels 210 are arranged vertically with the vertical drainage channels 210. Due to the arrangement of the drainage channels 210, part of the rainwater can be discharged along the drainage channels 210, and the drainage effect is good.

[0066] In the embodiment, optionally, the limiting ring 220 and the floating ball 230 in the drainage channel 210 extending in the first direction, the inner circumferential surface of the limiting ring 220 is arranged as a tapered surface, and the cross-sectional shape of the limiting ring 220 perpendicular to the first direction is circular or elliptical, the floating ball 230 abuts against the inner circumferential surface of the limiting ring 220, and the floating ball 230 is used to float up under the liquid buoyancy and open the water passage hole surrounded by the limiting ring 220.

[0067] It should be understood that after the rainwater enters the drainage channel 210, the floating ball 230 rises under the action of the buoyancy, opens the water passage hole surrounded by the limiting ring 220, and the rainwater can be discharged along the drainage channel 210, avoiding excessive rainwater accumulated in the drainage channel 210. And when the amount of rainwater is small, the rainwater can be stored in the drainage channel 210 and intercepted by the floating ball 230, the rainwater accumulated in the drainage channel 210 can play a heat insulation role and also has a certain waterproof performance.

It should be understood that the limiting protrusion can be an annular protrusion, and the limiting effect is good. By limiting the rising height of the floating ball 230, the drainage rate is adjusted, the time of rainwater staying in the drainage channel 210 is prolonged, and the rainwater is used to play a role of heat preservation and heat dissipation.

[0069] In the embodiment, optionally, the waterproof layer 300 and the fireproof and heat insulation layer 200 can be fixed by glue.

[0070] It should be understood that the connection mode of the waterproof layer 300 and the fireproof and heat insulation layer 200 is simple, and the preparation cost is low.

[0071] In the embodiment, optionally, the waterproof layer 300 and the outer protective layer 400 are fixed by glue.

[0072] It should be understood that the connection mode of the waterproof layer 300 and the outer protective layer 400 is simple, and the preparation cost is low.

[0073] It should be understood that the outer protective layer 400 can be a polyurethane protective layer, which has excellent heat insulation, sound insulation, moisture resistance, corrosion resistance, convenient construction, beautiful appearance, and easy maintenance. The outer protective layer 400 can also be a polystyrene board, which is light in weight, easy to construct, has excellent heat preservation effect, and has long service life. The outer protective layer 400 can also be a gypsum board protective layer, which is light in weight, moisture-proof, corrosion-proof, fireproof, beautiful and durable, and easy to decorate.
