Description

Technical Field

[0001] The invention belongs to the technical field of prefabricated houses, and in particular relates to a modular light steel structure prefabricated house. Background Art

[0002] Prefabricated buildings refer to the transportation of prefabricated building components to the construction site, where the assembly and construction of the building components are completed on site. Compared with cast-in-place buildings, prefabricated buildings have the advantages of integrated construction and decoration, high construction efficiency, and shortened construction period, which meet the development requirements of green buildings. European and American countries started early and developed rapidly in the field of prefabricated buildings. Among them, in the United States, prefabricated buildings account for a high proportion, reaching 90%. As a country with a shortage of housing, Germany has a fairly mature level of industrialized construction with the further improvement of industrialization technology.

[0003] The main feature of prefabricated buildings is that a large number of on-site construction and quality control processes are transferred to standardized factories, which is conducive to improving the overall quality of the building and promoting the improvement of construction efficiency. The application of new lightweight and high-strength materials has certain advantages over traditional materials, making up for the shortcomings of traditional materials in terms of performance, and has a driving significance for improving the quality of prefabricated buildings.

[0004] Lightweight prefabricated houses are generally divided into steel frame units and panel units, which are directly assembled by light steel frame units and panel units. Most of the panel units in the existing technology are still made of hard materials. This design has poor performance and is not suitable for the development needs of current prefabricated house technology. Summary of the invention

[0005] In view of the above technical problems, the object of the present invention is to provide a modular light steel structure prefabricated house to improve the performance of the panel unit.

[0006] To achieve the purpose of the present invention, the present invention is implemented by the following technical solutions: A modular light steel structure assembled house comprises a house body, wherein the house body comprises a light steel frame unit and a panel unit, wherein the house body is directly assembled by the light steel frame unit and the panel unit, wherein the panel unit comprises a composite roof plate, wherein the composite roof plate comprises a wood frame layer and a composite layer, wherein the wood frame layer covers the composite layer; wherein the composite layer comprises, from inside to outside, a natural plant fiber panel layer, a waterproof and breathable material layer, a first particle board layer, a nanoporous solid material layer, a thermal insulation material layer, a second particle board layer and a building board layer.

[0007] Furthermore, the natural plant fiber panel layer is made of bamboo panel or wood panel.

[0008] Furthermore, the waterproof and breathable material layer is made of one-way breathing paper, or a waterproof and breathable membrane, or a microporous film.

[0009] Furthermore, the first and second particle board layers are both made of LSB board.

[0010] Furthermore, the nanoporous solid material layer is made of nano aerogel.

[0011] Furthermore, the thermal insulation material layer is made of aluminum silicate fiber felt or glass wool.

[0012] Furthermore, the building board layer adopts fiber reinforced cement board.

[0013] Furthermore, the panel unit also includes a composite wall panel.

[0014] Furthermore, the composite wallboard contains silver-loaded nano-titanium dioxide.

[0015] Beneficial effects of the present invention: The composite roof of the present invention adopts a seven-layer composite structure, so that the composite roof has the functions of heat preservation, heat insulation, waterproofing and sound insulation, which makes up for the shortcomings of traditional materials in terms of performance, adapts to the development needs of modern prefabricated housing technology, and has a strong value for promotion and use.

[0018] The present invention is described in detail below with reference to the accompanying drawings and embodiments. Example

[0019] A modular light steel structure assembled house comprises a house body, wherein the house body comprises a light steel frame unit and a panel unit, the house body is directly assembled by the light steel frame unit and the panel unit, and the panel unit comprises a composite roof plate.

[0020] The composite roof panel includes a wood frame layer covering the composite layer, and the wood frame layer is the main load-bearing frame of the wall panel. Figure 1As shown, the composite layer includes seven layers, the first layer 1 is the inner layer, the seventh layer 7 is the outer layer, and the third to sixth layers are the middle layers. The inner layer of the first layer 1 adopts a 20mm thick bamboo panel, and a wood panel can also be used. The outer layer of the seventh layer 7 adopts a 10mm thick fiber reinforced cement board, so that the composite roof has a high load-bearing capacity and stability, and also has good thermal insulation and waterproof effects. The second layer 2 adopts one-way breathing paper or waterproof breathable film, so that the composite roof has waterproof and breathable properties. The third layer 3 and the sixth layer 6 both use LSB boards, which improves the deformation resistance of the composite roof. The fourth layer 4 is sealed with 3.5mm hard nano aerogel filling material to improve the thermal insulation effect of the composite roof. The fifth layer 5 is filled with 50mm thick glass fiber wool wrapped in PET film, which improves the thermal insulation and sound insulation effects of the composite roof.

[0021] The composite layer of the composite roof panel of the present invention adopts a seven-layer structural design, and each layer cooperates with each other, thereby greatly improving the thermal insulation, heat insulation, waterproof and sound insulation effects of the composite roof panel. Example

[0022] The only difference from the above embodiment 1 is that the panel unit further comprises a composite wallboard, and the composite wallboard contains silver-loaded nano-titanium dioxide. The preparation method of the silver-loaded nano-titanium dioxide is as follows: S1: First, add 1.4 g of ethanol and an equal volume of deionized water into a beaker, then add 0.03 g of solid silver nitrate, and adjust the pH to 2-4 with nitric acid to obtain solution A; under magnetic stirring, mix 14 g of anhydrous ethanol and 4 g of glacial acetic acid, and add 8 g of tetrabutyl titanate dropwise into the mixture to form solution B; S2: under vigorous magnetic stirring, solution A was added to solution B at a rate of 1 drop per second, and then polyethylene glycol was quickly added dropwise (to prevent agglomeration), stirring was continued for 30 minutes, and dimethyl sulfoxide was added to increase its stability and hydrophilicity, thereby obtaining a silver-loaded nano-titanium dioxide sol; S3: The silver-loaded nano-titanium dioxide sol was placed in a forced air drying oven, fully dried at 60°C for 24 h, ground into powder, and calcined in a muffle furnace for 3 h to obtain the silver-loaded nano-titanium dioxide powder. The preparation was completed.

[0023] This embodiment greatly improves the antibacterial performance of the composite wallboard by adding silver-loaded nano-titanium dioxide.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. Therefore, although the present invention has been described in detail with reference to the above embodiments, it should be understood by those skilled in the art that the present invention can still be modified or replaced by equivalents. All technical solutions and improvements that do not depart from the spirit and scope of the present invention should be included in the scope of the claims of the present invention.
