A fully assembled steel-concrete structure roof

Technical Field

The utility model belongs to the technical field of assembled buildings, and in particular relates to a fully assembled steel-concrete structure roof.

Background Art

Prefabricated buildings are a construction method that uses factory-prefabricated components and then assembles and installs them on site. The sloping roofs of current prefabricated buildings are usually constructed using cast-in-place or semi-cast-in-place methods, which are cumbersome to construct and cannot be fully assembled due to difficulties in formwork support, steel bar binding, concrete pouring and vibration.

The current prefabricated buildings, such as the previously disclosed patent "CN116290584A", have disclosed a prefabricated curved roof panel, which uses a modular integral curved steel mold and is produced in a prefabricated component factory, eliminating the mold assembly speed and saving mold assembly time. However, the prefabricated curved roof panel adopts a single piece integral type, and when there is no floor-type load-bearing structure support, it is difficult to install and the assembly is inflexible; it cannot be applied to the style of traditional ancient buildings, and is not conducive to the roof to achieve drainage and waterproofing functions.

The information disclosed in the above background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as admitting or suggesting in any form that the information constitutes the prior art already known to those skilled in the art.

Through the above-mentioned embodiment, the roof steel frame and the roof panel are used as the basic prefabricated component forms, the modules are uniformly corresponding, the installation is convenient, and the full assembly of the roof structure is realized. The structure of the prefabricated roof panel 2 draws on the style of traditional ancient Chinese architecture, and the end has an arc-shaped structure design similar to the end of a tile. On the one hand, it provides protection for the connection of the prefabricated roof steel frame 1, which is beneficial to the drainage and waterproofing functions of the roof. On the other hand, it makes the prefabricated roof more traditional and national, suitable for the construction of large-span roof structures, suitable for homestay buildings, renovation of dilapidated houses, garden buildings, etc., so that the building roof has distinct traditional and national characteristics, thereby achieving the purpose of this embodiment.

As a preferred technical solution of this embodiment, the through hole 15 of the prefabricated roof steel frame 1 is a vertical waist-shaped hole, which is convenient for leaving vertical margin for corresponding adjustment during installation.
