[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] like Figure 1-3 As shown, a steel skeleton light composite panel comprises a light steel galvanized steel frame 1, a cold-drawn low-carbon steel wire mesh 2 is arranged at the lower position inside the light steel galvanized steel frame 1, a concrete filling core layer 3 and a polymer mortar layer 4 are arranged inside the light steel galvanized steel frame 1, and the polymer mortar layer 4 is located above the concrete filling core layer 3, and a protective component 5 is arranged at the top of the light steel galvanized steel frame 1;

[0022] The protection component 5 includes a light steel galvanized steel frame 26 and a protection plate 13. The light steel galvanized steel frame 26 is installed on the top of the light steel galvanized steel frame 1, and the protection plate 13 is installed on the top of the light steel galvanized steel frame 26. Bolt columns 14 are arranged at the four corners through the upper and lower ends of the light steel galvanized steel frame 26 and the protection plate 13, and the bottom end of the bolt column 14 is fixedly connected to the top of the light steel galvanized steel frame 1. Positioning columns 7 are arranged at the four corners inside the light steel galvanized steel frame 26. A sound insulation board layer 8 is installed at the lower position inside the light steel galvanized steel frame 26. A waterproof layer 10, a thermal insulation layer 11, and a high temperature resistant layer 12 are arranged in sequence inside the light steel galvanized steel frame 26 and at the top of the sound insulation board layer 8, and the high temperature resistant layer 12 is located at the top.

[0023] In the present embodiment, the inner lower position of the light steel galvanized steel frame 2 6 is set in an "L" shape, and positioning holes are opened at the upper and lower ends of the thermal insulation layer 11, the waterproof layer 10, the sound insulation layer 8, and the high temperature resistant layer 12, and the positioning column 7 passes through the positioning hole. The positioning column 7 and the positioning hole facilitate the installation and positioning of the thermal insulation layer 11, the waterproof layer 10, the sound insulation layer 8, and the high temperature resistant layer 12, which is convenient for personnel to assemble.

[0024] In this embodiment, the upper and lower ends of the thermal insulation layer 11 are respectively bonded to the high temperature resistant layer 12 and the waterproof layer 10, and the thermal insulation layer 11 is a rock wool layer. The rock wool is made of natural rocks such as basalt, gabbro, dolomite, iron ore, bauxite, etc. as the main raw materials. After being melted at a high temperature of more than 1450°C, it is centrifuged into fibers at high speed using an internationally advanced four-axis centrifuge. At the same time, a certain amount of adhesive, dust-proof oil, and water-repellent agent are sprayed in, and then collected by a cotton collector, through a pendulum method, and three-dimensional cotton laying, and then solidified and cut. It has excellent thermal insulation and fire retardant functions.

[0025] In the present embodiment, a number of equally spaced sound-absorbing holes are provided through the upper and lower ends of the sound-insulating board layer 8, and the sound-absorbing holes are filled with glass wool 9. The sound-insulating board layer 8 and the sound-absorbing holes can block noise. The glass wool 9 is a cotton-like material formed by fiberizing molten glass. It is an artificial inorganic fiber with the advantages of good molding, low volume density, high thermal conductivity, thermal insulation, good sound absorption performance, corrosion resistance, and stable chemical properties.

[0026] In this embodiment, the high temperature resistant layer 12 is made of high temperature and high pressure resistant resin, glass fiber alkali-free cloth and composite reinforcement material, and the top surface of the high temperature resistant layer 12 is bonded to the bottom surface of the protective plate 13. The high temperature resistant layer 12 is made of high temperature and high pressure resistant resin, glass fiber alkali-free cloth and composite reinforcement material, and is laminated by a mold, which overcomes the problem that the greater the density, the greater the pressure resistance and the poor thermal insulation effect. It has the advantages of high mechanical strength, high temperature resistance, flame retardancy, good thermal stability, and is not easy to deform during long-term continuous use. The high temperature resistant layer 12 is bonded to the protective plate 13 to prevent the high temperature resistant layer 12 from detaching upward after installation, which is convenient for pressing the high temperature resistant layer 12 and the lower plate.

[0027] In this embodiment, the outer ring of the bolt column 14 is threadedly connected with a fixing nut located above the protective plate 13, the top surface size of the protective plate 13 matches the size of the light steel galvanized steel frame 26 and the light steel galvanized steel frame 1, and the protective plate 13 and the light steel galvanized steel frame 26 are detachably connected to the light steel galvanized steel frame 1 through the bolt column 14. The protective plate 13, the insulation layer 11, the high temperature resistant layer 12, the sound insulation board layer 8, and the waterproof layer 10 are not made of an integrated filling. When damaged, the fixing bolts can be unscrewed to release the fixation of the protective plate 13, and then the damaged part can be taken out for disassembly and replacement, without the need for overall replacement, which can reduce the maintenance cost.

[0028] It should be noted that the utility model is a steel skeleton light composite panel. When in use, first, the light steel galvanized steel frame 1 and various components can be moved to a suitable position at the construction site as needed, and then they can be spliced ​​as needed. During splicing, because the bolt columns 14 are set at the four corners of the top of the light steel galvanized steel frame 1, and the light steel galvanized steel frame 26 and the protective plate 13 are provided with sockets that match the bolt columns 14, the construction personnel can directly align the sockets on the light steel galvanized steel frame 26 with the bolt columns 14, and then put the light steel galvanized steel frame 26 on the light steel galvanized steel frame 1, and then the various components can be loaded into the light steel galvanized steel frame 26. After loading, the protective plate 13 can be covered on the light steel galvanized steel frame 26, and then the fixing nuts can be tightened to combine the light steel galvanized steel frame 26, the protective plate 13, and the light steel galvanized steel frame 1 into one. After the assembly is completed, it can be directly transported to the construction site for assembly according to the existing technology;

[0029] After installation, the composite board can achieve good noise reduction and sound insulation effects by filling the core layer 3, the sound-absorbing holes, and the glass wool 9 with concrete. At the same time, the waterproof layer 10, the high-temperature resistant layer 12, and the thermal insulation layer 11 can achieve waterproof, fireproof, and flame-retardant effects.

[0030] At the same time, the protective plate 13 is arranged at the top, which can play an isolating and protective role, reducing the probability of the light steel galvanized steel frame 26 being damaged by impact, and the protective plate 13, the insulation layer 11, the high temperature resistant layer 12, the sound insulation board layer 8, and the waterproof layer 10 are not made of integrated filling. When damaged, each part can be disassembled and replaced without the need for overall replacement, which can reduce the maintenance cost.
