Description

Technical Field

[0001] The utility model relates to the technical field of steel structure buildings, in particular to a box-type modular light steel roof steel structure. Background Art

[0002] Steel structure modular buildings have gradually come into people's view. The so-called modular house is to divide the components of the house into different functional modules, and realize factory manufacturing through modular, standardized and universal production. The house can be assembled on site anytime and anywhere, and the whole assembly process is more convenient and quick. Steel structure box-type modularization belongs to the field of prefabricated and assembled buildings. It is produced by industrialized methods and then transported to the site for installation. In order to realize industrialized production, it is necessary to standardize the components of the module and limit the form of the space to an extremely limited range. Therefore, steel structure box-type modularization is generally only suitable for residential buildings with relatively certain functional requirements and simple room composition.

[0003] When installing the roof steel structure of the box-type modular house in the prior art, the roof steel structure is usually directly connected and assembled on the top of the box-type modular house. When the steel structure of the box-type modular light steel roof is exposed to hail and rain, the light steel roof steel structure often transmits a large noise into the box-type modular house. Although sound insulation material is arranged on the back of the light steel roof steel structure, the sound insulation material is usually simply bonded or nailed. After the sound insulation material ages, the noise at the light steel roof steel structure will affect the central environment in the box-type modular house. In addition, the sound insulation material at the light steel roof steel structure is also relatively simple, which is not convenient for the subsequent replacement and maintenance of the central personnel. This cannot meet the low-noise living needs of the box-type modular light steel house. For this reason, we propose a box-type modular light steel roof steel structure. Utility Model Content

[0004] The main purpose of the utility model is to provide a box-type modular light steel roof steel structure, in which a noise reduction mechanism is arranged at the roof steel structure body used for the box-type modular house.
