For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0040] In this embodiment, a roof structure construction method is disclosed. Figure 1 The whole process of the roof structure construction method is shown. Figure 2 The side structure in which the roof frame involved in the roof structure construction method is installed on the main structure is shown; Figure 3 The cross-sectional structure of the roof frame is shown.

[0041] Please refer to Figures 1 to 3 , the roof structure construction method of the present invention includes: In order to achieve the above-mentioned purpose, the present invention provides a roof structure construction method, including: S1: embedding the embedded parts on the building main body and serving as the fixing points connecting the building main body with the roof frame;

[0042] S2: installing some panels on the roof frame, and hoisting the pre-assembled roof frame to a preset position of the building body;

[0043] S3: fixing the roof frame to the building body through the embedded parts;

[0044] S4: Install the panel on the lower surface of the roof frame to complete the construction of the roof structure.

[0045] In step S1, the embedded parts are pre-embedded parts or post-embedded parts. When the building body is poured, the pre-embedded parts are buried in the building body as fixed points connecting the building body with the roof frame 1; or, after the building body is completed, the post-embedded parts are set on the building body as fixed points connecting the building body with the roof frame 1.

[0046] Before step S2, a workbench can be built on the construction ground, and the roof frame 1 can be built on the ground, which can ensure the assembly quality of the roof frame 1, facilitate inspection, and make assembly simpler, reduce the construction difficulty, improve work efficiency, and omit the construction of an aerial work platform, saving a lot of materials and labor, and reducing construction costs. In addition, there is no need to set up a scaffolding or a floor-standing scaffolding as a construction operation platform, which reduces the occupation of the work surface, provides a work surface for roof and exterior wall operations, speeds up the construction period, and reduces costs.

[0047] Among them, in this embodiment, the roof frame 1 includes: a first frame 11, a second frame 12 arranged on one side of the first frame 11, wherein the first frame 11 and the second frame 12 include a plurality of horizontal beams and a plurality of vertical beams vertically arranged on the plurality of horizontal beams; the panel is arranged on the first frame 11; one side of the second frame 12 and one side of the first frame 11 are respectively connected to the embedded parts 3. The vertical beams not only enhance the longitudinal stability of the frame, but also form a stable grid structure with the horizontal beams, effectively dispersing various loads from above. In this embodiment, the first frame 11, the second frame 12 and the outer edge of the main structure 2 form a triangle, and the size of the angle between the first frame 11 and the second frame 12 can be adjusted according to actual needs.

[0048] In step S2, when installing panels on the surface of the roof frame 1, in order to maintain the flexibility of construction, a layer without installing panels will be reserved on the roof frame. In this embodiment, any layer is selected from the first frame 11 and the second frame 12, that is, the distance between any horizontal beam and the horizontal beam adjacent to it. Panels are not installed within this range, leaving space for welding and installation of the roof frame 1, which is convenient for construction personnel to install and fix the roof frame 1. In specific construction operations, the bottom layer of the first frame 11 and the second frame 12 is generally selected without installing panels. The pre-assembled roof frame 1 is hoisted to the preset position of the building main body, including: hoisting the assembled roof frame 1 as a whole by a crane; flipping the hoisted roof frame 1 in the air to adjust the installation angle between the roof frame 1 and the building main body; and fitting the roof frame 1 with the adjusted installation angle to the preset position of the building main body. The crane can adjust the structure of the roof frame 1 as needed. Due to different construction requirements, the roof frame 1 has various shapes, which are not only large in size but also complex in structure. Therefore, the position of the roof frame 1 is adjusted in the air by a crane, and mechanized construction is performed, which reduces the labor intensity of workers, reduces high-altitude operations, and reduces safety risks.

[0049] After step S3 and before step S4, the method further includes: inspecting the roof frame 1 fixed on the main body of the building; and executing step S4 after the inspection is qualified. In step S4, after the inspection of the roof frame 1 is completed, the panels are installed on the outer surface of the roof frame 1 where the panels are not installed, so as to ensure the integrity and beauty of the roof.

[0050] Among them, in this embodiment, the second frame 12 in the roof frame 1 is fixed to the first frame 11 by welding. The welding connection performance is good, which ensures the integrity of the first frame 11 and the second frame 12, making the roof frame 1 more solid and firm. Diagonal braces 13 are evenly arranged between the first frame 11 and the second frame 12. The diagonal braces 13 are used to support the first frame 11 and the second frame 12, effectively dispersing the stress that may be generated between the frames, and enhancing the stability and wind pressure resistance of the overall structure. One end of the diagonal brace 13 is fixed to the end of the first frame 11, and the other end is fixed to the middle of the second frame 12, providing additional support for the frame.

[0051] The panel is an aluminum plate. With its advantages of light weight, corrosion resistance and easy processing, the aluminum plate not only provides good waterproof and thermal insulation performance for the building, but also adds a beautiful scenery to the building with its unique texture and color. The panel is fixed to the roof frame 1 by riveting. This connection method not only ensures the close connection between the panel and the frame, but also avoids the thermal stress problem that may be caused by traditional welding, further improving the safety and durability of the structure. At the same time, the surface of the aluminum plate can be sprayed as needed to achieve a visual effect that is coordinated with the overall architectural style.

[0052] Among them, an anti-corrosion layer is arranged on the surface of the roof frame 1, which can effectively resist the erosion of harmful factors such as acid rain and ultraviolet rays in the natural environment, ensuring that the frame can still maintain its original strength and stability in harsh environments.

[0053] The roof frame 1 is a steel frame, which not only meets the building's requirements for bearing capacity, but also provides the possibility of realizing complex and varied building forms. In the embodiment of the present invention, the specific structure of the roof frame can be set to different structures according to the situation.

[0054] The embedded part 3 is a steel plate, which is reliably connected to the roof frame 1 during the construction process to ensure the continuity and stability of the roof frame 1 as a whole.

[0055] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
