[0058] like Figure 1 to Figure 5 As shown, the construction method for eaves installation provided in this embodiment is used to install the eaves structure 100 to the eaves installation position 210 of the building body 200. The eaves structure 100 includes an eaves and ceiling combination module 1, a gutter module 2 and a sloping roof module 3.

[0059] The construction methods of cornice installation include:

[0060] Prefabricate and assemble cornice and ceiling combination module 1, gutter module 2 and sloping roof module 3 on the ground;

[0061] The eaves and ceiling combination module 1 is lifted to the eaves installation part 210 by a lifting device, and the eaves and ceiling combination module 1 is fixedly connected to the bottom 211 of the eaves installation part 210;

[0062] Lift the gutter module 2 close to the eaves and ceiling combination module 1 by the lifting device, so that the gutter module 2 is connected to the gutter groove reserved on the eaves and ceiling combination module 1;

[0063] The sloping roof module 3 is lifted to the eaves installation part 210 by a lifting device, and is fixedly connected to the slope 212 of the eaves installation part 210 , and one end of the sloping roof module 3 close to the gutter module 2 is connected to the gutter module 2 .

[0064] Among them, the eaves and ceiling combination module 1 includes an eaves part and a suspended top part, the suspended top part is connected to the bottom 211 of the eaves installation part 210, the eaves part is cantilevered out of the outside of the eaves installation part 210, and the gutter module 2 is connected to the eaves part. The gutter module 2 is used for water collection and drainage, and can collect external water (such as rainwater) falling from the sloping roof module 3, and discharge the collected external water to prevent external water from entering the eaves and ceiling combination module 1.

[0065] This embodiment provides a construction method for cornice installation, where the cornice structure 100 is divided into a cornice and ceiling combination module 1, a gutter module 2, and a sloping roof module 3, and then each module is prefabricated and assembled on the ground in advance, and then each assembled module is hoisted and connected to the building main body 200 in sequence. By completing most of the assembly work on the ground, the high-altitude operation time is greatly reduced, which can improve construction efficiency and reduce safety risks. At the same time, the operation difficulty is low when assembling on the ground, and it is easier to ensure construction accuracy. In addition, when the module assembly operation is performed on the ground, other construction operations can be performed simultaneously on the building main body 200, thereby improving the overall construction efficiency and making the construction progress more controllable and rapid.

[0066] The lifting equipment may be a truck crane, a crawler crane, an electric hoist, etc., which is not specifically limited here.

[0067] Specifically, the cornice and ceiling combination module 1, the gutter module 2 and the sloping roof module 3 all include a keel structure and a curtain wall structure. When the cornice and ceiling combination module 1, the gutter module 2 and the sloping roof module 3 are prefabricated and assembled on the ground, the prefabrication and assembly of any of the modules specifically includes the following steps:

[0068] An assembly tire frame 4 is arranged on the ground;

[0069] The keel structure of the module is assembled and adjusted by assembling the tire frame 4; specifically, the keel structure can be set as a steel structure;

[0070] After the keel structure is assembled, the curtain wall structure is connected to the keel structure;

[0071] Carry out a comprehensive inspection and test on the assembled modules to ensure that they meet the installation requirements.

[0072] Among them, the comprehensive inspection test includes appearance inspection and waterproof function inspection to ensure that the systems of the assembled modules function normally, the structure is stable, and meet the design requirements.

[0073] The assembly frame 4 is provided to facilitate the assembly and adjustment of different components in each module and ensure the assembly accuracy of each module. In particular, for modules with curved surfaces, the assembly frame 4 is used to adjust the curved surface accuracy and installation quality.

[0074] The assembled tire frame 4 can adopt a conventional structure in the art, which will not be described in detail here.

[0075] More specifically, the curtain wall structure includes a waterproof layer and a decorative surface layer, and the decorative surface layer is arranged on the outer surface of the keel structure. Connecting the curtain wall structure to the keel structure includes:

[0076] After the keel structure is assembled, the waterproof layer is first installed on the keel structure, and then the decorative surface layer is installed on the outer surface of the keel structure.

[0077] By completing the installation of a waterproof layer on the ground, the waterproof performance of each module is ensured, thereby improving the waterproof effect of the entire eaves structure 100; the outermost decorative surface layer plays a decorative and aesthetic role. During installation, it is necessary to ensure that the decorative surface layer is flat, beautiful, and in line with the design effect.

[0078] In some embodiments, before the cornice and ceiling assembly module 1, the gutter module 2 and the sloping roof module 3 are prefabricated on the ground, the following steps are further included:

[0079] Model establishment: According to the architectural design drawings, a complete cornice structure model is established and collision checks are performed to ensure the precise positioning and coordination of the cornice and ceiling combination module 1, the gutter module 2 and the sloping roof module 3;

[0080] Further design: Based on the premise of the whole modular installation of the cornice structure 100, an integrated design of installing the cornice structure 100 to the building main body 200 is performed;

[0081] Component processing: According to the drawings and requirements of the in-depth design, the components of the eaves and ceiling combination module 1, the gutter module 2 and the sloping roof module 3 are processed to ensure that each component meets the design specifications and quality requirements.

[0082] During model building, the eaves structure model may be a BIM model (Building Information Modeling), which refers to a digital three-dimensional model created based on architectural design drawings, including the shape, material, connection method, etc. of the eaves structure 100.

[0083] Through such settings, model building helps to discover and solve potential conflicts or problems in the design stage, thereby reducing rework and adjustments during the construction process. The in-depth design is based on the modular installation of the entire cornice structure 100, ensuring that both the design and construction stages can be carried out in a modular manner, thereby ensuring the high consistency and coordination of all modules during the installation process, and avoiding installation mismatch problems on site. Based on this, component processing is then carried out, which is conducive to ensuring the processing quality and processing accuracy of the components.

[0084] In some embodiments, the keel structure of the module is assembled and adjusted by assembling the tire frame 4, specifically including:

[0085] Combined with the eaves structure model, 3D scanning technology is used to measure and adjust the keel structure.

[0086] Through such a setting, 3D scanning technology can be used to measure and locate each part of the keel structure with high precision, and compared with the BIM model of the cornice structure to ensure that the actual assembly position of the keel is completely consistent with the designed position. 3D scanning can also detect the deviation of the keel structure in real time, quickly identify errors in size, position or shape, so that the construction team can make timely adjustments to avoid cumulative errors. In other words: it is conducive to improving the assembly accuracy of the keel structure and reducing the risk of deformation during the subsequent installation process.

[0087] In some embodiments, after assembling and adjusting the keel structure of the module by assembling the tire frame 4, the following steps are further included:

[0088] Perform error measurement on the building main body 200;

[0089] According to the assembly of the keel structure and the error measurement results of the building main body 200, combined with the eaves structure model, the three-dimensional scanning technology is used to check and debug the connector 5 of the module, which is used to connect the module to the building main body 200.

[0090] like Figure 1 As shown, a connecting piece 5 is shown on the cornice and ceiling combination module 1, and similar arrangements are used in the remaining modules.

[0091] By measuring the error of the building main body 200, the deviation between the building main body 200 and the design model in actual construction can be accurately identified. Combined with the assembly of the keel structure and the eaves structure model, the three-dimensional scanning technology can be used to accurately adjust the size, angle, etc. of the connector 5 to compensate for these deviations, ensuring that the module can be accurately connected to the building main body 200, reducing the risk of deformation during subsequent installation.

[0092] In some embodiments, during the process of installing the cornice and ceiling assembly module 1, the gutter module 2 and the sloping roof module 3 to the building main body 200, the three-dimensional scanning technology is used to coordinately control the fixed points of the connector 5 one by one. Such a setting can ensure that the position of the fixed point of each connector 5 during installation is completely consistent with the design requirements, which can avoid the accumulation of deviations, the occurrence of misalignment or misalignment, and improve the accuracy of the overall installation.

[0093] In some embodiments, after the cornice and ceiling assembly module 1, the gutter module 2 and the sloping roof module 3 are all installed to the building body 200, the following steps are further included:

[0094] The joints are waterproofed and decorated.

[0095] By performing secondary waterproofing treatment on the gaps and cracks that may occur during the installation and fixing process, and completing the necessary decoration, the waterproof performance is further enhanced to prevent leakage problems.

[0096] In some embodiments, after the cornice and ceiling assembly module 1, the gutter module 2 and the sloping roof module 3 are all installed to the building body 200, the following steps are further included:

[0097] A roof covering layer 6 is arranged on the top of the building body 200 , so that one end of the sloping roof module 3 away from the gutter module 2 is overlapped or connected to the roof covering layer 6 .

[0098] With such arrangement, the roof covering layer 6 covers and protects the top of the building body 200 .

[0099] In this embodiment, the eaves structure 100 is first installed on the building body 200, and then the roof covering layer 6 is set. In other embodiments, the order of construction can also be changed. The roof covering layer 6 is first set on the top of the building body 200, and then the eaves structure 100 is installed. The specific order can be determined according to actual conditions.

[0100] Optionally, the roof covering layer 6 is a waterproof layer to prevent rainwater and snow water from penetrating into the interior of the building body 200.

[0101] Optionally, the roof covering layer 6 is a thermal insulation layer to provide thermal insulation and reduce energy consumption.

[0102] Note that the above are only preferred embodiments of the present invention and the technical principles used. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments and substitutions can be made by those skilled in the art without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in more detail through the above embodiments, the present invention is not limited to the above embodiments, and may include more other equivalent embodiments without departing from the concept of the present invention, and the scope of the present invention is determined by the scope of the appended claims.
