Description

Technical Field

[0001] This invention relates to the field of building engineering, and more specifically to a method for installing electromechanical pipelines under a large-span metal roof. Background Technology

[0002] Large-span metal roofs typically refer to metal roof structures with a span of 30 meters or more. These roof structures are widely used in large public buildings such as stadiums, exhibition centers, and airport terminals, and have advantages such as being lightweight and high-strength, quick to construct, and aesthetically pleasing.

[0003] Large-span metal roofs are typically characterized by their large area and high ceilings, thus requiring higher standards for waterproofing and load-bearing capacity. Therefore, when installing electromechanical pipelines under such roofs, traditional methods requiring drilling, such as expansion bolts or chemical anchors, cannot be used for direct fixing. Drilling not only damages the waterproofing layer, leading to leaks, but also makes the metal edges prone to rusting, affecting the roof's lifespan. Furthermore, drilling can compromise the structural strength of the large-span metal roof, reducing its load-bearing capacity and creating potential safety hazards.

[0004] When installing electromechanical pipelines under a long-span metal roof, the following methods are typically used to avoid drilling directly into the metal roof:

[0005] 1. Installed on structural beams: This refers to fixing electromechanical pipelines to structural beams under the metal roof after the building is completed by setting additional suspension components or other conversion structures. However, the spacing of structural beams is often greater than the spacing of pipeline supports and hangers, which cannot meet the pipeline hanging requirements and poses safety hazards. At the same time, installing conversion structures on high-altitude structural beams is often inefficient, difficult to construct, requires professional equipment and personnel, and has high economic costs.

[0006] 2. Arbitrarily fixing pipes to the roof purlin structure: This refers to the practice of directly drilling holes in the purlins to install pipe supports after the roof structure construction is completed and during the installation of mechanical and electrical pipelines, when it is discovered that there are no pipe hanging points. This practice poses significant quality and safety risks. Arbitrary drilling can damage the load-bearing capacity of the purlins and may also damage the roof waterproofing structure. Furthermore, the increased pipe load has not been adequately verified and confirmed, adversely affecting the structural safety of the roof and even posing a risk of collapse.

[0007] Therefore, how to install electromechanical pipelines under large-span metal roofs in order to avoid damaging the waterproof layer and structural strength of the metal roof, ensure the safety and durability of the installation of electromechanical pipelines, and at the same time improve construction efficiency and aesthetics and reduce installation costs is a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0008] To address the aforementioned problems, the purpose of this invention is to provide a method for installing electromechanical pipelines under large-span metal roofs. This method not only avoids damaging the waterproofing layer and structural strength of the metal roof, ensuring the safety and durability of the installed electromechanical pipelines, but also improves construction efficiency and aesthetics while reducing installation costs.

[0009] The method for installing electromechanical pipelines under a large-span metal roof according to the present invention includes the following steps:

[0010] BIM modeling was performed on the large-span metal roof to construct a 3D model;

[0011] Calculate the installation point X where electromechanical pipelines can be installed and its load-bearing threshold;

[0012] Based on the 3D model, the electromechanical pipelines to be installed are designed in detail, and a 3D detailed design model is generated.

[0013] Based on the 3D detailed design model, the load threshold of each electromechanical pipeline is calculated.

[0014] Calculate the installable electromechanical pipelines and their corresponding installation points Y, and generate a 3D pipeline layout model;

[0015] Design of supporting structures for electromechanical pipelines based on 3D pipeline layout model;

[0017] Based on the 3D panoramic model, output the purlin processing drawings and supporting structure design drawings for factory prefabrication;

[0018] When installing purlins on a long-span metal roof, the supporting structure should be pre-installed or installed simultaneously.

[0019] Furthermore, in some embodiments, the installation points X for which electromechanical pipelines can be installed and their load-bearing thresholds are calculated. First, the three-dimensional coordinates of all installation points X are obtained from the 3D model. The installation points X are located on the large-span metal roof where purlins are installed. Based on the three-dimensional coordinates of the installation points X, modeling tests are performed and the load-bearing thresholds of each installation point X in the 3D model are calculated. A mapping table between the three-dimensional coordinates of the installation points X and the load-bearing thresholds is output.

[0020] Furthermore, in some embodiments, the installable electromechanical pipelines and their corresponding installation points Y are calculated. First, the three-dimensional coordinates of the installation point X covered by the electromechanical pipelines to be installed are obtained from the 3D detailed design model, which are the three-dimensional coordinates of the installation point Y. The load thresholds are statistically classified. The mapping relationship table between the three-dimensional coordinates of the installation point Y and the load thresholds and bearing capacity thresholds is output.

[0021] Based on the mapping relationship table of the three, calculate and output the three-dimensional coordinates of the electromechanical pipelines that can be installed and their installation points Y;

[0022] The three-dimensional coordinates of the installable electromechanical pipelines and their corresponding installation points Y are converted into feature parameters and input into the 3D detailed design model to generate a 3D pipeline layout model.

[0023] Furthermore, in some embodiments, the design of the support structure is based on the number and shape of the purlins at mounting point Y and their position relative to the electromechanical pipelines, and the support structure is used to support the electromechanical pipelines.

[0024] Furthermore, in some embodiments, before prefabrication in the factory, mechanical simulation and verification are performed on the 3D panoramic model, and BIM technology and parametric modeling tools are used to optimize and adjust the 3D panoramic model based on the verification results.

[0025] Furthermore, in some embodiments, before outputting the purlin processing drawing and the support structure design drawing, the holes that need to be set on the purlin for installing the support structure at the corresponding installation point Y are merged into the purlin processing drawing, and the purlin processing drawing is output for factory prefabrication; the support structure is identified and grouped, and the support structure design drawing is output for factory prefabrication.

[0026] Furthermore, in some embodiments, the purlin is configured as C-shaped or Z-shaped, including an upper edge plate, a lower edge plate, and a vertical plate disposed in the vertical direction of the upper and lower edge plates, and the supporting structure includes a supporting bracket fixed to the vertical plate by bolts.

[0027] Furthermore, in some embodiments, the supporting structure includes one purlin or at least two parallel purlins; it also includes a supporting bracket configured in an L-shape, U-shape or inverted T-shape; the supporting bracket includes at least one arm plate arranged parallel to the vertical plate, and a support plate arranged perpendicular to the arm plate and fixed to the bottom of the arm plate; the arm plate and the vertical plate are fixedly installed by bolts; electromechanical pipelines are arranged on the support plate.

[0028] Furthermore, in some embodiments, the supporting structure includes one purlin or at least two parallel purlins; it also includes a U-shaped supporting bracket, which includes at least two hangers or suspension lines perpendicular to the purlins, and a support plate perpendicular to the hangers or suspension lines and fixed to the bottom of the hangers or suspension lines; electromechanical pipelines are arranged on the support plate; the upper parts of the hangers or suspension lines can be fixedly arranged on the vertical plates of one or more purlins respectively; the upper parts of the hangers or suspension lines are connected to the vertical plates through a conversion plate, which is fixedly connected to the vertical plates in a first direction and connected to the hangers or suspension lines in a second direction.

[0029] Furthermore, in some embodiments, the upper part of the suspension rod or suspension line is directly fixedly connected to the conversion plate, or connected to the conversion plate through a support rod, with multiple ends of the support rod fixed to the conversion plate, and the upper part of the suspension rod or suspension line fixedly mounted on the support rod.

[0030] It should be understood that, within the scope of this invention, the above-described technical features of this invention and the technical features specifically described below (such as in the embodiments) can be combined with each other to form new or preferred technical solutions. Due to space limitations, they will not be described in detail here.

[0031] Compared with the prior art, the present invention has the following technical effects:

[0032] First, no drilling is required on the metal roof, which avoids damaging the waterproof layer and structural strength of the metal roof, ensuring the safety and durability of the electromechanical pipeline installation.

[0033] Second, through modeling, refinement, verification, and prefabrication, the electromechanical pipeline support structure is deeply integrated with the large-span metal roof. The metal roof purlins are used to install electromechanical pipelines, eliminating the need for on-site drilling of the purlins. This effectively improves construction efficiency and the degree of prefabrication, ensuring safe and reliable construction quality and aesthetically pleasing results, while also effectively reducing installation costs.

Wherever possible, the same reference numerals will be used in all the drawings to denote the same or similar parts.

[0049] Figure 1A flowchart illustrating a method for installing electromechanical pipelines under a large-span metal roof according to an embodiment of the present invention is shown. The method for installing electromechanical pipelines under a large-span metal roof provided in this application includes the following steps:

[0050] Step S10: Perform BIM modeling on the large-span metal roof and construct a 3D model.

[0051] Specifically, a plan design can be carried out first for the large-span metal roof. Based on the plan design, BIM technology can be used to build a 3D model. The 3D model includes the overall appearance of the large-span metal roof, the purlin and steel reinforcement structure, and the selection of profile dimensions.

[0052] Step S20: Calculate the installation point X where electromechanical pipelines can be installed and its load-bearing threshold;

[0053] More preferably, the installation points X for which electromechanical pipelines can be installed and their load-bearing thresholds are calculated. First, the three-dimensional coordinates of all installation points X are obtained from the 3D model. The installation points X are located on the large-span metal roof where purlins are installed. Based on the three-dimensional coordinates of the installation points X, modeling tests are performed and the load-bearing thresholds of each installation point X in the 3D model are calculated. The mapping relationship table between the three-dimensional coordinates of the installation points X and the load-bearing thresholds is output.

[0054] In some specific implementations, all locations with purlins are selected from the 3D model as preset installation points X. In this invention, the supporting structure needs to be installed on the purlins, and the three-dimensional coordinate set (x1, x2, x3) of its installation point X is obtained. 3。。。 x n The model was tested based on the three-dimensional coordinate set, and the set of load-bearing thresholds Y (y1, y2, y3, y4, y5) for each installation point X in the 3D model was calculated. 3。。。 y n Table 1 shows the mapping relationship between the three-dimensional coordinates of the installation point X and the load-bearing threshold Y.

[0055]

[0056]

[0057] Step S30. Based on the 3D model, perform detailed design of the electromechanical pipelines to be installed, and generate a 3D detailed design model;

[0058] Specifically, a preliminary plan design can be performed first for the electromechanical pipelines to be installed, resulting in a plan view of the electromechanical pipelines. Then, BIM technology is used to further refine the design on the 3D model, resulting in a 3D detailed design model. The 3D detailed design model includes the overall appearance of the large-span metal roof, the purlin and steel reinforcement structure, the layout of electrical pipelines, and the selection of profile dimensions. The main purpose is to use BIM technology to refine the design of the electromechanical pipelines to be installed, and in conjunction with the roof architectural drawings, to complete the comprehensive pipeline layout and identify the electromechanical pipelines that need to be installed using purlins.

[0059] Step S40. Based on the 3D detailed design model, calculate the load threshold of each electromechanical pipeline;

[0060] Step S50. Calculate the installable electromechanical pipelines and their corresponding installation points Y, and generate a 3D pipeline layout model;

[0061] More preferably, the installable electromechanical pipelines and their corresponding installation points Y are calculated. First, the three-dimensional coordinates of the installation points X covered by the electromechanical pipelines to be installed are obtained from the 3D detailed design model, which are the three-dimensional coordinates of the installation points Y. Then, the load thresholds are statistically classified. A mapping table between the three-dimensional coordinates of the installation points Y and the load thresholds and bearing capacity thresholds is output. Based on the mapping table, the three-dimensional coordinates of the installable electromechanical pipelines and their installation points Y are calculated and output. The three-dimensional coordinates of the installable electromechanical pipelines and their corresponding installation points Y are converted into feature parameters and input into the 3D detailed design model to generate a 3D pipeline layout model.

[0062] In some specific implementations, based on the 3D detailed design model, various pipeline loads are statistically classified for reference and design review. Loads that can be suspended using metal roof purlins are verified and identified, and the pipeline layout is re-completed after pipeline screening. For heavy pipelines that cannot be installed using purlins, alternative installation methods must be designed. For electromechanical pipelines that can be installed, their three-dimensional coordinates and the corresponding Y-coordinates of their installation points are converted into feature parameters and input into the 3D detailed design model to generate a 3D pipeline layout model.

[0063] Step S60. Design the supporting structure for electromechanical pipelines based on the 3D pipework layout model;

[0064] Specifically, based on the 3D pipework layout model, an appropriate installation structure type should be selected and designed.

[0065] More preferably, the design of the supporting structure is based on the number and shape of the purlins at installation point Y, and their position relative to the electromechanical pipelines. The supporting structure is used to support the electromechanical pipelines. For example, it is usually necessary to consider the number of purlins, how to install a single purlin, and how to install multiple purlins; it is necessary to consider the shape of the purlins, such as whether Z-shaped or C-shaped purlins are used for metal roofing; it is necessary to consider whether the routing direction of the electromechanical pipelines is parallel or perpendicular to the purlins; in addition, the size and weight of the electromechanical pipelines also place requirements on the supporting structure.

[0066] More preferably, the bolt spacing and bolt specifications selected for fixing the supporting structure in this invention are consistent with the bolt spacing and bolt specifications selected in the purlin overlap design, which facilitates factory prefabrication.

[0067] More preferably, the design and layout of the supporting structure should be combined with the structural nodes of the large-span metal roof to eliminate interference between the supporting structure and the purlins, braces, and other structures.

[0068] Step S70: Input the characteristic parameters of the supporting structure into the 3D pipework layout model to generate a three-dimensional panoramic model;

[0069] Step S80. Based on the 3D panoramic model, output the purlin processing drawing and the supporting structure design drawing for factory prefabrication;

[0070] More preferably, before prefabrication in the factory, the three-dimensional panoramic model is subjected to mechanical simulation and verification, and the three-dimensional panoramic model is optimized and adjusted using BIM technology and parametric modeling tools based on the verification results.

[0071] In some specific implementations, the optimization of the pipework layout model should be synchronized with the detailed design of the large-span metal roof. The construction unit submits the pipework layout drawings, pipeline loads, detailed drawings of the supporting structure, supporting structure layout drawings, purlin opening dimensions, and other data to the design unit. Mechanical simulation and verification are then performed on the 3D panoramic model, and BIM technology and parametric modeling tools are used to optimize and adjust the 3D panoramic model based on the verification results. If stress exceeds limits, adjustments can typically be made by changing the position of the supporting structure, changing the purlin material, modifying the purlin cross-sectional dimensions, or locally reinforcing the purlins to meet load requirements. After various optimization measures, the final pipework layout drawings, supporting structure layout drawings, supporting structure detailed drawings, and purlin opening dimensions are completed. This ensures that all installation points have undergone load verification, guaranteeing the structural safety.

[0072] More preferably, before outputting the purlin fabrication drawing and the support structure design drawing, the holes required for installing the support structure on the purlin at the corresponding installation point Y are merged into the purlin fabrication drawing, and the purlin fabrication drawing is output for factory prefabrication; the support structure is identified and grouped, and the support structure design drawing is output for factory prefabrication. The purlin openings are completed in the factory, reducing the impact of on-site openings on the purlin's mechanical properties; saving significant manual opening costs, reducing construction safety risks, and improving construction efficiency.

[0073] Step S90. When installing purlins on a long-span metal roof, pre-install or simultaneously install the supporting structure.

[0074] In some specific implementations, based on the pipework layout drawing, supporting structure design drawing (supporting structure layout drawing, supporting structure detail drawing), and purlin fabrication drawing, the required profile specifications, lengths, quantities, bolt hole positions, and other parameters can be calculated. The supporting structure components are then prefabricated and grouped. When the roof purlins are ready for installation or other conditions are met, pre-installation or simultaneous assembly and installation of the supporting structure can begin. The construction of large-span metal roof purlins and the prefabrication and installation of the supporting structure can be carried out concurrently, potentially shortening the construction period by 30%. After the supporting structure construction is completed, the purlins are arranged in rows and lines with uniform and neat spacing, resulting in an aesthetically pleasing appearance.

[0075] More preferably, such as Figures 2 to 6 As shown, the purlin 100 is configured as C-shaped or Z-shaped, including an upper edge plate 101, a lower edge plate 102, and a vertical plate 103 disposed in the vertical direction of the upper and lower edge plates. The supporting structure 200 includes a supporting bracket 300 fixed to the vertical plate 103 by bolts 201.

[0076] More preferably, the supporting structure 200 includes one purlin 100 or at least two parallel purlins 100; it also includes a supporting bracket 300 configured in an L-shape, U-shape or inverted T-shape; the supporting bracket 300 includes at least one arm plate 301 arranged parallel to the vertical plate 103, and a supporting plate 302 arranged perpendicular to the arm plate 301 and fixed to the bottom of the arm plate 301; the arm plate 301 and the vertical plate 103 are fixedly installed by bolts 201; the electromechanical pipeline 400 is arranged on the supporting plate 302.

[0077] More preferably, the supporting structure 200 includes one purlin 100 or at least two parallel purlins 100; it also includes a U-shaped supporting bracket 300, which includes at least two hangers 303 or hangers 304 perpendicular to the purlins 100, and a supporting plate 302 perpendicular to the hangers 303 or hangers 304 and fixed to the bottom of the hangers 303 or hangers 304; electromechanical pipelines are installed on the supporting plate 302; the upper part of the hangers 303 or hangers 304 can be fixedly installed on the vertical plate 103 of one or more purlins 100 respectively; the upper part of the hangers 303 or hangers 304 is connected to the vertical plate 103 through a conversion plate 305, which is fixedly connected to the vertical plate 103 in a first direction and connected to the hangers 303 or hangers 304 in a second direction.

[0078] More preferably, the upper part of the rod 303 or the wire 304 is directly fixedly connected to the conversion plate 305, or connected to the conversion plate 305 through a support rod 306, with multiple ends of the support rod 306 fixed to the conversion plate 305, and the upper part of the rod 303 or the wire 304 fixedly mounted on the support rod 306.
