Description

Technical Field

[0001] The present invention relates to the technical field of building pipeline design, and in particular to a pipeline comprehensive optimization design method based on BIM technology. Background Art

[0002] As buildings become larger and more complex, there are more and more electromechanical pipelines in the building. How to reasonably design the direction and location of various electromechanical pipelines, minimize the building height occupied by the pipelines, thereby raising the ceiling height of each area of ​​the building and facilitating the construction of the construction unit has always been a problem that electromechanical professional designers have been troubled by.

[0003] At present, when using BIM technology for comprehensive optimization design of pipelines, the design habit is that the drawings of each discipline are designed separately, lacking a unified plan, and lacking reasonable allocation of space arrangements for each discipline. Pipeline conflicts, intersections, or unreasonable directions often occur, which even affect construction, leading to quality rework, construction delays, and material waste.

[0004] Therefore, developing a comprehensive pipeline optimization design method suitable for overall optimized layout is a technical problem that needs to be solved urgently. Summary of the invention

[0005] Due to the above-mentioned defects in the prior art, the present invention provides a pipeline comprehensive optimization design method based on BIM technology, which utilizes BIM technology to achieve the optimal design of the direction and position of various electromechanical pipelines in the building, thereby minimizing the building height occupied by pipeline installation and avoiding mutual interference between pipelines.

[0006] To achieve the above object, the present invention provides a pipeline comprehensive optimization design method based on BIM technology, comprising the following steps:

[0007] Step S1, using BIM software to establish a combined model of building structure and electromechanical specialty;

[0008] Step S2: inputting general principles of comprehensive pipeline layout into the BIM model;

[0009] Step S3: Based on the principle that pipelines are from the medium source to the user point, check the entry point on the path of each system and clarify the preliminary plan for the intersection area between the pipelines of each professional system;

[0010] Step S4: Pipelines are grouped according to different specialties and arranged in groups in an optimized manner;

[0011] Step S5, merging the groups in step S4 by region, and optimizing the length and height of each group;

[0012] Step S6: Pipelines are divided into layers, and pipelines with elevation differences within the threshold range are adjusted to the same elevation according to the lowest elevation, and comprehensive supports and hangers and seismic supports and hangers are arranged to obtain the final pipeline comprehensive optimization design drawings.

[0013] The pipeline comprehensive optimization design method first specifies the general principles of pipeline layout, then clarifies the preliminary plan for the intersection area between professional system pipelines, and then performs group optimization, and then performs regional merge group optimization, and finally performs pipeline stratification, unifies the management elevations within the threshold range of elevation difference, and obtains the pipeline comprehensive optimization design plan. This combination of design steps not only realizes that the design of each group meets the public principle, but also avoids collision interference between pipelines in each group through regional merge optimization group design, and at the same time, the final pipeline stratification design minimizes the building use height occupied by pipeline installation. The entire design step is reasonably arranged, which can realize standardized rapid and accurate design, and meet the requirements of most pipeline comprehensive optimization designs.

[0014] In some embodiments, in step S1, the BIM software is first used to establish the architectural and structural models of the building, and then the BIM software is used to establish the electromechanical model; then the electromechanical models of each specialty are combined into a whole and linked to the building structure model to obtain a combined model of the building structure and the electromechanical model.

[0015] In some embodiments, in step S2, the general principles of the comprehensive layout of pipelines include small pipes giving way to large pipes, branch pipes giving way to main pipes, pressurized pipes giving way to unpressurized pipes, general pipes giving way to air ducts, hot water pipes on top and cold water pipes on the bottom, water supply pipes on top and drainage pipes on the bottom, air conditioning condensate pipes and drainage pipes are arranged first, and the distance between the electrical bridge and the outer wall of the water pipe (including the insulation layer) and the wall is not less than 100 mm, the distance between the straight section of the air duct and the wall is not less than 150 mm, the horizontal spacing of the same profession and the spacing of different professions are specified, the spacing between pipelines with a nominal diameter greater than 500 mm is at least 300 mm, the horizontal spacing between the weak current bridge and the fire protection electrical bridge and the electrical bridge is at least 300 mm, the parallel clearance between the bus duct and the cable bridge and the general pipeline is not less than 400 mm, and the vertical clearance is not less than 300 mm.

[0016] Furthermore, the horizontal spacing between the same profession is 100 mm, and the spacing between different professions is 200 mm.

[0017] By adopting the above technical solution, the general principle of comprehensive layout of pipelines provides a larger range of limitations for the preliminary design of pipelines, so that there is enough room for operation in the next step of grouping design.

[0018] In some embodiments, in step S4, all electromechanical pipelines are divided into three groups according to water supply and drainage, HVAC, and electrical engineering, namely Group G, Group N, and Group D.

[0019] Further, in step S5, according to the length Ga and height Gb of group G, the length Na and height Nb of group N, and the length Da and height Db of group D, group G, group N and group D are combined together; the width of the pipeline intersection area is L, and the vertical height is H;

[0020] When Ga+Na+Da+600≤L, the minimum vertical installation height of the pipeline is Max{Gb, Nb, Db};

[0021] When Ga+Na+Da+600>L, calculate the area of ​​each group of G, N and D, which are Gs, Ns and Ds respectively, and sum up the total area of ​​each group S=Gs+Ns+Ds, then the ideal minimum installation height of the pipeline area h=S / L;

[0022] Taking the L×h area as the benchmark, and meeting the principle that the pipeline is 50mm away from the bottom of the beam, 100mm away from the wall, and the spacing between groups G, N and D is 200mm, adjust the length and height of each group to optimize the pipeline layout in this area.

[0023] By adopting the above technical solution, the regional merging and grouping can be standardized, and the length and height of each group can be optimized and adjusted to facilitate the collaborative implementation of the solution.

[0024] In some embodiments, in step S6, the threshold range is 300 mm.

[0025] Compared with the prior art, the present invention has the following advantages or beneficial effects:

[0026] (1) The design method of the present invention can quickly and accurately optimize the layout of various types of mechanical and electrical pipelines according to the size and clear height of each area of ​​the building.

[0027] (2) The design method of the present invention can minimize the building space occupied by electromechanical pipelines and avoid mutual interference between pipelines.

[0028] (3) The design method of the present invention takes advantage of the BIM technology modeling to intuitively display the layout of mechanical and electrical pipelines in various areas of the building in three dimensions; all mechanical and electrical pipelines and integrated hanging brackets can be quickly and accurately formed into two-dimensional construction drawings and provided to the construction unit to guide construction and installation.

[0033] Example

[0034] See also Figure 1 This embodiment provides a pipeline comprehensive optimization design method based on BIM technology, including the following steps:

[0035] Step S1, using BIM software to establish a combined model of building structure and electromechanical specialty;

[0036] Step S2: inputting general principles of comprehensive pipeline layout into the BIM model;

[0037] Step S3: Based on the principle that pipelines are from the medium source to the user point, check the entry point on the path of each system and clarify the preliminary plan for the intersection area between the pipelines of each professional system;

[0038] Step S4: Pipelines are grouped according to different specialties and arranged in groups in an optimized manner;

[0039] Step S5, merging the groups in step S4 by region, and optimizing the length and height of each group;

[0040] Step S6: Pipelines are divided into layers, and pipelines with elevation differences within the threshold range are adjusted to the same elevation according to the lowest elevation, and comprehensive supports and hangers and seismic supports and hangers are arranged to obtain the final pipeline comprehensive optimization design drawings.

[0041] After that, the arranged electromechanical pipelines are exported as two-dimensional construction drawings, including the pipeline installation location and elevation information, and submitted to the construction unit for construction. The layout of the comprehensive support and hanger is exported as a cross-sectional drawing and submitted to the construction unit to find a manufacturer for in-depth design.

[0042] The pipeline comprehensive optimization design method first specifies the general principles of pipeline layout, then clarifies the preliminary plan for the intersection area between professional system pipelines, and then performs group optimization, and then performs regional merge group optimization, and finally performs pipeline stratification, unifies the management elevations within the threshold range of elevation difference, and obtains the pipeline comprehensive optimization design plan. This combination of design steps not only realizes that the design of each group meets the public principle, but also avoids collision interference between pipelines in each group through regional merge optimization group design, and at the same time, the final pipeline stratification design minimizes the building use height occupied by pipeline installation. The entire design step is reasonably arranged, which can realize standardized rapid and accurate design, and meet the requirements of most pipeline comprehensive optimization designs.

[0043] As a more specific implementation method, in step S1, the BIM software is first used to establish the models of the architecture and structure of the building, and then the BIM software is used to establish the model of the electromechanical specialty; then the electromechanical models of each specialty created are integrated into a whole and linked to the building structure model to obtain a combined model of the building structure and the electromechanical specialty.

[0044] As a more specific implementation, in step S2, the general principles of the comprehensive layout of pipelines include small pipes giving way to large pipes, branch pipes giving way to main pipes, pressurized pipes giving way to non-pressurized pipes, general pipes giving way to air pipes, hot water pipes on top and cold water pipes on the bottom, water supply pipes on top and drainage pipes on the bottom, air conditioning condensate pipes and drainage pipes are arranged first, and the distance between the electrical bridge and the outer wall of the water pipe (including the insulation layer) and the wall is not less than 100mm, the distance between the straight pipe section and the wall is not less than 150mm, the horizontal spacing between the same profession and the spacing between different professions is stipulated, the spacing between pipelines with a nominal diameter greater than 500mm is at least 300mm, the horizontal spacing between the weak current bridge and the fire protection electrical bridge and the electrical bridge is at least 300mm, the parallel clearance between the bus duct and the cable bridge and the general pipeline is not less than 400mm, and the vertical clearance is not less than 300mm. Furthermore, the horizontal spacing between the same profession is 100mm, and the spacing between different professions is 200mm. By adopting the above technical solution, the general principle of comprehensive layout of pipelines provides a larger range of limitations for the preliminary design of pipelines, so that there is enough room for operation in the next step of grouping design.

[0045] In step S4, for example, all electromechanical pipelines are divided into three groups according to water supply and drainage, HVAC, and electrical, which are marked as Group G, Group N, and Group D. It can be understood that the professional grouping of electromechanical pipelines can be based on the specific professional categories involved in the project, and can also include drainage, strong and weak electricity, water supply and drainage, HVAC, fire protection, etc.

[0046] As an example, in step S5, according to the length Ga and height Gb of group G, the length Na and height Nb of group N, and the length Da and height Db of group D, group G, group N, and group D are combined together; the width of the pipeline intersection area is L, and the vertical height is H;

[0047] When Ga+Na+Da+600≤L, the minimum vertical installation height of the pipeline is Max{Gb, Nb, Db};

[0048] When Ga+Na+Da+600>L, calculate the area of ​​each group of G, N and D, which are Gs, Ns and Ds respectively, and sum up the total area of ​​each group S=Gs+Ns+Ds, then the ideal minimum installation height of the pipeline area h=S / L;

[0049] Taking the L×h area as the benchmark, and meeting the principle that the pipeline is 50mm away from the bottom of the beam, 100mm away from the wall, and the spacing between groups G, N and D is 200mm, adjust the length and height of each group to optimize the pipeline layout in this area.

[0050] By adopting the above technical solution, the regional merging and grouping can be standardized, and the length and height of each group can be optimized and adjusted to facilitate the collaborative implementation of the solution.

[0051] In some embodiments, in step S6, the threshold range is 300 mm. It is understandable that the threshold range can also be adjusted according to the requirements of the engineering project.

[0052] In summary, the present invention provides a pipeline comprehensive optimization design method based on BIM technology. First, the general principles of pipeline layout are specified, and then the preliminary plan of the intersection area between professional system pipelines is clarified. After group optimization, regional merge group optimization is performed, and finally pipeline stratification is performed to unify the management elevations within the threshold range of elevation difference, and obtain the pipeline comprehensive optimization design plan. The present invention not only realizes that the design of each group meets the public principle, but also avoids collision interference between pipelines in each group by optimizing the group design by regional merge. At the same time, the final pipeline stratification design minimizes the building use height occupied by pipeline installation. The entire design step is reasonably arranged, and standardized rapid and accurate design can be achieved, meeting the requirements of most comprehensive optimization designs of pipelines.
