Technical Field

[0001] The utility model relates to the technical field of assembled roofs, in particular to an assembled steel roof structure of a green building. Background Art

[0002] The rooftop prefabricated steel structure of a green building is a modern construction technology that combines sustainability and efficiency, aiming to reduce the impact of buildings on the environment while improving building performance and construction efficiency. Prefabricated steel structures typically use recyclable materials, which helps reduce waste and environmental impact during the construction process. The recyclability of steel also means that the building can be disassembled and reused after its life span.

[0003] At present, after the frame of the prefabricated steel structure roof is installed, in order to improve the thermal insulation effect of the roof, it is often necessary to repeatedly lay and install the three-layer structure of steel plate, rock wool and TPO surface material on the frame roof. The construction efficiency is low, resulting in a long construction period.

[0004] In view of the above problems, the present utility model document proposes a roof assembled steel structure for a green building. Utility Model Content

[0007] A green building roof assembled steel structure, comprising:

[0008] A roof steel frame, wherein a connecting rod is welded at the center of the top of the roof steel frame;

[0009] Multiple composite board blocks are installed on both sides of the connecting rod and the roof steel frame to simplify the installation steps of the multi-layer insulation structure, thereby reducing the construction period. The multiple composite board blocks are formed from bottom to top by hot pressing a load-bearing plate, an insulation interlayer, a waterproof interlayer and a lightweight steel plate through an adhesive.

[0010] In a possible design, two docking blocks are symmetrically fixedly provided on the high side of the composite board block, and docking grooves for clamping corresponding docking blocks are provided on both sides of the connecting rod.

[0011] In a possible design, two mounting steel sheets are symmetrically fixedly provided on the lower side of the composite board block, and the mounting steel sheets are fixedly connected to the side walls of the roof steel frame by corresponding bolts.

[0012] In a possible design, the thermal insulation interlayer is made of extruded polystyrene, which not only has excellent thermal insulation performance but also has higher compressive strength and lower water absorption.

[0013] In a possible design, the waterproof interlayer is made of EPDM rubber, which has excellent weather resistance, chemical resistance and weldability.

[0014] In a possible design, the surface of the lightweight steel plate is galvanized to protect the steel from corrosion and extend its service life.

[0015] In a possible design, a drainage channel is provided on the upper surface of the lightweight steel plate.

[0016] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit the present invention.

[0017] In the present application, when installing the composite board block, firstly, two docking blocks symmetrically arranged on the high side of the composite board block are clamped with the docking grooves arranged on both sides of the connecting rod to achieve the initial fixation of the composite board block above the roof steel frame, and then, two mounting steel sheets symmetrically arranged on the low side of the composite board block are bolted to the side walls of the roof steel frame to further fix the composite board block and ensure its close connection and stability with the roof steel frame.

[0018] The utility model has the following beneficial effects:

[0019] The utility model prefabricates the composite plate blocks into an integrated structure through modular design, and the modular connection design of the roof steel frame and the composite plate blocks simplifies the installation steps of the multi-layer insulation structure and significantly reduces the construction period.

[0020] The utility model adopts an insulating interlayer made of extruded polystyrene, which has excellent thermal insulation performance, effectively maintains indoor temperature stability and improves living comfort. The waterproof interlayer made of EPDM rubber has excellent weather resistance, chemical resistance and weldability, ensuring the waterproof performance of the roof and preventing rainwater penetration.

[0021] The surface galvanizing treatment of the lightweight steel plate in the utility model effectively protects the steel from corrosion, while the design of the drainage concave channel prevents water accumulation from damaging the roof, thereby extending the service life of the roof.

[0022] The utility model not only simplifies the installation steps of the multi-layer thermal insulation structure and reduces the construction period, but also improves the thermal insulation effect and waterproof performance of the roof through reasonable material selection and structural design, thus achieving the goal of green building.
