Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a construction method of a roof system. Background Art

[0002] With the continuous development and progress of architectural design, more and more public buildings not only meet basic functional needs but also have aesthetic value. For example, stadiums, convention and exhibition centers and other venue buildings have become business cards that reflect the charm of a city because of their unique shapes and artistic sense.

[0003] In construction engineering, the roof system refers to the roof structure system of the building. Due to the large span of stadium-type buildings, the roof system of stadium-type buildings is currently constructed by first making prefabricated components in the factory, and then welding each prefabricated component in sequence at the construction site to finally form the roof system. Although on-site welding ensures stability, on-site high-altitude operations are complicated and have high safety risks. To solve this problem, a modular installation construction method is proposed in the prior art, which divides the roof system into several modules, assembles each module on the ground, and then lifts each module to the installation position in sequence for installation. Although this construction method reduces the workload of some high-altitude operations, the connection between modules still needs to be carried out at high altitudes. It is difficult to control the connection quality during high-altitude operations, and it is easy to have problems such as inaccurate installation and component deformation, which affects the final effect.

[0004] Therefore, it is urgent to propose a construction method of a roof system to solve the above technical problems. Summary of the invention

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0065] like Figures 1 to 8 As shown, the construction method of the roof system provided in this embodiment is used to install the roof system 100 on the top of the building body 200.

[0066] The roof system 100 includes a main structure 1, a keel structure 2 and a roof structure 3, wherein the keel structure 2 is connected to the top of the main structure 1, and the roof structure 3 is connected to the top of the keel structure 2. The main structure 1 is the main load-bearing and supporting structure of the roof system 100, which can be a steel structure, the keel structure 2 is a secondary supporting structure for bearing and fixing the roof structure 3, and the roof structure 3 is the outer surface structure of the roof system 100.

[0067] The construction methods of the roof system include:

[0068] S1. Assembling the main structure 1 on the ground;

[0069] S2, installing the keel structure 2 to the top of the main structure 1;

[0070] S3, lifting the main structure 1 and the keel structure 2 to a preset position off the ground by means of the lifting device 6, so that the main structure 1 and the keel structure 2 are deformed due to their own weight and structural stress during the lifting process;

[0071] S4, after the main structure 1 and the keel structure 2 remain stable, the roof structure 3 is installed on the top of the keel structure 2 to complete the assembly of the roof system 100;

[0072] S5. Lift the assembled roof system 100 to the top of the building main body 200 by means of the lifting device 6, and connect the roof system 100 to the peripheral structure 210 on the top of the building main body 200.

[0073] When the steps S3 to S5 are specifically implemented, the main structure 1 and the keel structure 2 are first lifted together by the lifting device 6. After being lifted to the preset position, the lifting device 6 is not unloaded, but only suspended, that is, the main structure 1 and the keel structure 2 are still suspended at the preset position by the lifting device 6. Then, the roof structure 3 is installed at a low altitude. After the installation of the roof structure 3 is completed, the roof system 100 is assembled as a whole, and the same lifting device 6 is continuously started until the assembled roof system 100 is lifted to the installation position on the top of the building main body 200.

[0074] The construction method of the roof system provided in this embodiment completes the assembly of the main structure 1 and the keel structure 2 on the ground, so that most of the connection work is carried out on the ground, and the assembled roof system 100 is lifted and installed on the top of the building main body 200 in an integrated manner, which greatly reduces the workload of high-altitude operations, improves safety and construction efficiency, reduces the difficulty of operation when assembling on the ground, and is easier to control and ensure the quality of connection. In addition, the assembled main structure 1 and the keel structure 2 are lifted together, so that they are deformed due to their own weight and structural stress during the lifting process, and then the roof structure 3 is installed after the deformation is stable, which is conducive to better control of the connection quality between the roof structure 3 and the keel structure 2, and avoids problems such as inaccurate installation or component deformation caused by unstable deformation or difficult operation during high-altitude operations, thereby ensuring the final installation accuracy and connection effect.

[0075] Alternatively, if Figure 5 As shown, there are two connection points between the lifting device 6 and the main structure 1, and the two connection points are symmetrically arranged at opposite ends of the main structure 1, so that the main structure 1 maintains force balance during the lifting process.

[0076] Optionally, the lifting device 6 may be an electric hoist, a truck crane, a crawler crane, etc., which is not specifically limited here.

[0077] It should be noted that: when the keel structure 2 is installed on the top of the main structure 1 in step S2, there is no need to wait for the main structure 1 to be fully assembled, and the keel structure 2 can be installed simultaneously with the main structure 1.

[0078] In some embodiments, assembling the main structure 1 on the ground includes:

[0079] An assembly tire frame 4 is arranged on the ground;

[0080] The main structure 1 is assembled and adjusted by assembling the tire frame 4.

[0081] Through such an arrangement, the assembly frame 4 is conducive to conveniently assembling and adjusting the main structure 1, thereby ensuring the assembly accuracy of the main structure 1.

[0082] The assembled tire frame 4 can adopt a conventional structure in the art, which will not be described in detail here.

[0083] It is understandable that when the assembly frame 4 is used, the lifting device 6 needs to lift the main structure 1 and the keel structure 2 to be separated from the assembly frame 4. During the lifting process, the supporting points between the main structure 1 and the assembly frame 4 are gradually separated by unloading step by step, so as to avoid severe deformation or damage caused by one-time unloading.

[0084] In some embodiments, the keel structure 2 is installed on the top of the main structure 1, specifically including:

[0085] First, the keel structure 2 is modularly assembled to form a plurality of keel modules, and then the plurality of keel modules are installed one by one on the top of the main structure 1 .

[0086] The modular assembly of the keel structure 2 can be carried out off-site in advance, which is beneficial to reducing the installation time of the keel structure 2 and improving the installation efficiency of the keel structure 2 to the main structure 1.

[0087] like Figure 6 As shown, in some embodiments, the roof system 100 further includes a horseway 5. The horseway 5 is a passage for construction or maintenance, providing a safe passage route for construction personnel.

[0088] After the roof structure 3 is installed on the top of the keel structure 2, it also includes:

[0089] A horseway 5 is installed at the bottom of the main structure 1 .

[0090] The provision of the horseway 5 facilitates the safe passage of construction workers and provides convenience for the subsequent inspection and maintenance of the roof system 100.

[0091] like Figure 7 As shown, in some embodiments, after the assembled roof system 100 is lifted to the top of the building main body 200 by the lifting device 6 and the roof system 100 is connected to the peripheral structure 210 on the top of the building main body 200, the following steps are further included:

[0092] The keel structure 2 and the roof structure 3 are sequentially installed on the top of the peripheral structure 210. The keel structure 2 on the peripheral structure 210 is connected to the keel structure 2 in the roof system 100, and the roof structure 3 on the peripheral structure 210 is connected to the roof structure 3 in the roof system 100.

[0093] Through such an arrangement, after the roof system 100 and the peripheral structure 210 are initially connected, the keel structure 2 and the roof structure 3 are installed on the peripheral structure 210. In this way, it is possible to flexibly cope with various situations on the construction site. For example, the error accumulation problem that may occur during the overall lifting of the roof system 100 can be adaptively adjusted according to the error of the roof system 100 when the keel structure 2 and the roof structure 3 are installed on the peripheral structure 210, which is conducive to improving the flexibility of construction.

[0094] Optionally, after the installation of the roof system 100 and the construction of the top of the peripheral structure 210 are completed, the waterproof position can be inspected and a secondary waterproofing treatment can be performed to further improve the construction quality.

[0095] In some embodiments, the roof structure 3 is configured as a curtain wall structure. The curtain wall structure generally uses transparent or translucent materials, such as tempered glass, laminated glass, etc., which can play a role in lighting.

[0096] In some embodiments, the roof structure 3 is configured as a roofing material, which generally includes a waterproof layer, a thermal insulation layer, etc., and plays the role of waterproofing, thermal insulation, etc.

[0097] Of course, in some embodiments, the curtain wall structure and the roofing material can also be provided at the same time, depending on the actual situation.

[0098] In some embodiments, before assembling the main structure 1 on the ground, the method further includes:

[0099] Model building and collision check: according to professional drawings, build a complete three-dimensional model of the roof system 100, perform collision check, and ensure that there is no conflict between the components of the roof system 100;

[0100] Construction simulation analysis: Simulate and analyze the construction process, consider each construction step in the construction of the roof system 100, and obtain the stress and deformation of each component of the roof system 100 in each construction stage; specifically, the installation sequence of loads such as the keel structure 2 and the roof structure 3 should be considered in the simulation analysis to ensure reasonable structural deformation and structural safety;

[0101] Stress and displacement inspection: Check and confirm whether the corresponding stress and displacement meet the component installation conditions. If not, adjust the construction method and step arrangement and re-construction simulation analysis;

[0102] Determine the processing size of the component: Take the initial state of the component shown in the construction simulation analysis results as the processing basis to determine the processing size of the component;

[0103] Component processing: Process the main structure 1, keel structure 2 and roof structure 3 to ensure processing accuracy and quality.

[0104] Among them, during model establishment, the three-dimensional model of the roof system 100 can 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 roof system 100.

[0105] By establishing a three-dimensional model of the roof system 100 and performing a collision check, potential conflicts or interference problems between components can be discovered in advance; by simulating each step of the construction process in advance through construction simulation analysis, the stress and deformation of each component at each construction stage can be understood, thereby reducing rework and adjustments during the construction process; stress and displacement checks ensure that at each construction stage, the stress and deformation of each component of the roof system 100 are within a safe range; the processing dimensions of the components are determined based on the results of the construction simulation analysis. When determining the processing dimensions of the components, the actual stress and deformation of the components in the initial state, the installation process state, and the installation completion state obtained in the construction simulation analysis should be fully considered. The purpose is to be able to adjust the dimensions of the components in advance according to the predicted installation deviation and structural deformation during processing. For example, some components will bend and deform after installation. Compensation for the processing dimensions in advance can achieve the final installation completion state after installation.

[0106] Through such a setting, before the component processing, preliminary steps such as model building, construction simulation analysis, stress and displacement inspection, etc. are carried out to effectively improve the accuracy of construction planning and the processing accuracy of components, reduce construction errors and rework risks, and reduce construction costs, which is conducive to ensuring the final installation quality of the roof system 100 and the reliability of the overall project.

[0107] In some embodiments, the keel structure 2 is installed on the top of the main structure 1, specifically including:

[0108] In combination with the three-dimensional model of the roof system 100, the completed main structure 1 is measured using three-dimensional scanning technology. If there is an error between the measurement result and the construction simulation analysis result, the keel structure 2 is adjusted.

[0109] The completed main structure 1 is accurately measured by 3D scanning technology and compared with the 3D model and construction simulation analysis results, which can accurately identify the deviations of the main structure 1 during the actual installation process. Based on these deviations, the position and installation angle of the keel structure 2 are adjusted in time to ensure that its installation accuracy meets the design requirements.

[0110] In some embodiments, the main structure 1 and the keel structure 2 are lifted to a preset position off the ground by the lifting device 6, so that the main structure 1 and the keel structure 2 are deformed due to their own weight and structural stress during the lifting process, specifically including:

[0111] In combination with the three-dimensional model of the roof system 100, the three-dimensional scanning technology is used to measure and adjust the main structure 1 and the keel structure 2 during the lifting process.

[0112] With this setup, 3D scanning technology is used to monitor the deformation during the lifting process in real time, and compared with the expected deformation in the 3D model, deviations can be discovered and adjusted in a timely manner to ensure that the structural deformation is within a controllable range and the accuracy of subsequent installation is guaranteed.

[0113] In some embodiments, after the main structure 1 and the keel structure 2 remain stable, the roof structure 3 is installed on top of the keel structure 2, specifically including:

[0114] In combination with the three-dimensional model of the roof system 100, the roof structure 3 is measured and adjusted using three-dimensional scanning technology.

[0115] Through such a setting, the installation position and status of the roof structure 3 can be monitored in real time, which is conducive to ensuring the accurate docking of the roof structure 3 and the keel structure 2, reducing the deviation or misalignment caused by inaccurate installation position, and improving installation accuracy.

[0116] 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.
