Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of prefabricated assembly buildings, and particularly relates to a temporary reinforcing device for a concrete module superimposed roof. BACKGROUND

[0002] In recent years, the construction industry in China is undergoing a green development transformation and upgrading, among which "building industrialization" has become an important mode to promote sustainable development and gradually attracted the attention of the government. Modular integrated construction (MiC) is the latest achievement of the high development of prefabricated assembly building industrialization. This building system regards each room as a module unit, and all modules are prefabricated in the factory and transported to the site for assembly through reliable connection nodes.

[0003] Unlike traditional prefabricated buildings, modular integrated construction does not need to subdivide and transport basic components such as beams, slabs and columns to the site, but divides the building functions into different units, such as living rooms, bedrooms, kitchens and bathrooms. Room modules are mass-produced in factories, which not only include the simple assembly of structural components, but also cover the installation of mechanical and electrical pipelines and the simultaneous construction of decoration, thereby realizing the high integration and intelligentization of modular buildings.

[0004] In order to reduce the weight, modular integrated construction usually adopts a concrete thin-shell slab structure. After being transported to the site, the reserved steel bars of the thin-shell slab are bound and cast in situ to form an integral structure. However, due to the self-weight of the thin-shell roof, it may be deflected and cracked during decoration and transportation, which affects the appearance and even causes safety hazards. Therefore, temporary reinforcement of the top thin-shell slab is needed during decoration and transportation. CONTENT OF THE UTILITY MODEL
