Description

Technical Field

[0001] The invention belongs to the steel structure box-type modular technology, and in particular relates to an assembled integrated purlin roof for a box-type modular house and an installation method thereof. Background Art

[0002] Steel structure box-type modular house is a fast-building building model with advantages that traditional houses do not have. Due to the complexity of building functions, if the box-type modular house meets various functions and is designed in an integrated manner, the following problems will occur:

[0003] 1. If the box top module takes into account functions such as insulation and waterproofing, the module height will increase, which is not conducive to module standardization.

[0004] 2. The connection between non-standard box top modules and standard modules will increase the connection difficulty.

[0005] 3. In order to achieve the thermal insulation effect, it is necessary to fill the thermal insulation material between the keels and then fix the roof material, which is time-consuming and labor-intensive.

[0006] 4. It is not easy to set up gutters and downpipes on the roof module, which makes it difficult to achieve organized drainage and increases the project cost. Summary of the invention

[0022] 2. Overcome the connection difficulties caused by non-standard modular block labels.

[0023] 3. The roof, as an independent module, ensures the thermal performance of the building.

[0024] 4. The purlin support and purlin of the second keel of the roof module are used in coordination to achieve structural slope and save materials.

[0025] 5. The assembled integrated roof module uses metal rock wool sandwich panels as roof panels, and does not require a separate insulation layer, which is beneficial to simplifying the roof structure and speeding up construction and installation.

[0026] 6. Metal rock wool sandwich panels as roof panels have the advantages of light weight, high strength, good thermal insulation, good fire resistance, good drainage and waterproof performance, and bright colors.
