Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a BIM-based method and structure for the electromechanical installation of public buildings. Background Technology

[0002] BIM technology is widely used in the construction field due to its intuitive presentation, systematic working mode of cooperation among various disciplines, and comprehensive management approach. The application of BIM technology in the installation engineering of public buildings makes mechanical and electrical engineering more accurate, faster, more coordinated, and more convenient. The collision detection function of BIM technology can reduce building risks, optimize construction processes, and achieve refined management, which is the most prominent function of BIM technology. BIM technology has the following advantages for the mechanical and electrical engineering and mechanical and electrical pipeline installation in building construction: (1) The BIM three-dimensional information model provides visual guidance for the on-site installation of prefabricated pipes; (2) The pipes required for the installation project are all standardized prefabricated in the factory, avoiding secondary processing. After processing, the prefabricated pipe sections only need to be transported to the installation site for assembly and welding, saving construction time; (3) The pipe prefabrication processing technology is based on the established BIM model of the public building installation project. The information such as pipe section type, pipe material, wall thickness and length are all required by the project, maximizing the use of building materials and reducing construction costs.

[0003] Because electromechanical components and pipes are prefabricated using standardized methods, accurate alignment between components and coordination between electromechanical installation and other disciplines are crucial to prevent rework due to misalignment during final assembly. Therefore, precise control over the installation position of each component is essential. Traditionally, the installation of electromechanical components and pipes relies heavily on nearby walls or other structures as reference points. Errors in the installation position of these walls or structures can lead to deviations in the installation position of the electromechanical components or pipes within that section. This is especially true since most electromechanical components have at least two flanges connecting to the pipes. If the components are tilted, multiple flanges connecting to these flanges will deviate. Traditional BIM-based construction methods for electromechanical installation in public buildings often struggle to detect and adjust these installation errors in a timely manner, leading to synchronized deviations in subsequent pipework and resulting in significant rework later on. Summary of the Invention

[0004] The purpose of this invention is to address the problem of difficulty in accurately confirming the installation position of electromechanical equipment or electromechanical pipelines at each stage of construction, and to propose a BIM-based construction method and structure for electromechanical installation in public buildings.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A BIM-based construction method for electromechanical installation in public buildings includes the following steps:

[0007] S1. In the BIM-based 3D model coordinate diagram of electromechanical equipment and its pipelines, mark the coordinate points of the flange center of each electromechanical equipment and the coordinate points of the installation end of each electromechanical pipeline based on the coordinate points of the project base point, and import the coordinate point data into the control terminal.

[0008] S2. Install multiple GPS locators at the flange shaft of the electromechanical device, and set a unique physical address for each GPS locator in the control terminal so that the unique physical address of each GPS locator corresponds one-to-one with the coordinate address of the GPS locator when the electromechanical device is in the final installation position.

[0009] S3. Based on the position difference between the coordinate addresses of multiple GPS locators in the control terminal and the final coordinate address to be installed, the electromechanical device is moved manually or by a transfer device to drive the multiple GPS locators to move towards the final coordinate address, so that the coordinate addresses of the multiple GPS locators correspond one-to-one with the final coordinate address to be moved.

[0010] S4. Remove the GPS locator from the electromechanical system and clear and reset the address on the GPS locator. Then, install the GPS locator at the center of the end of the electromechanical pipeline connected to the electromechanical flange. Reset the unique physical address of the GPS locator in the control terminal so that the unique physical address of the GPS locator corresponds one-to-one with the coordinate address of the GPS locator when the electromechanical pipeline is in its final installation position. After connecting the electromechanical pipeline to the electromechanical flange, adjust the installation angle of the electromechanical pipeline so that the coordinate address of the GPS locator corresponds one-to-one with the final coordinate address of its final movement.

[0011] S5. Similarly, based on the installation of electromechanical pipes in S4, complete the installation of subsequent electromechanical pipes until the electromechanical pipes are finally connected with other electromechanical pipes.

[0012] As a further description of the above technical solution:

[0013] In step S3, the control terminal plans the optimal navigation route based on the position difference between the coordinate addresses of multiple GPS locators and the final coordinate address to be installed, thereby achieving the optimal route movement of the electromechanical equipment.

[0014] As a further description of the above technical solution:

[0015] In step S5, when the electromechanical pipeline is finally closed, there is no need to install a GPS locator in the last installed electromechanical pipeline. The two ends of the electromechanical pipeline can be directly connected to the flanges of the electromechanical or other electromechanical pipelines.

[0016] As a further description of the above technical solution:

[0017] A BIM-based construction method for electromechanical installation in public buildings includes a GPS locator, which is detachably installed at the center of the flange of each electromechanical component or at the center of the end of the electromechanical pipe via a positioning component.

[0018] As a further description of the above technical solution:

[0019] The positioning component includes a support column whose end axis is fixedly connected to a GPS locator. At least three positioning columns arranged in a circular array are fixedly connected to the end of the support column near the GPS locator. Each positioning column has a slider that slides along the axis of the positioning column. The support column has a sliding sleeve that slides and adjusts along the axis of the support column. The sliding sleeve is connected to each slider via a connecting rod.

[0020] As a further description of the above technical solution:

[0021] The two ends of the connecting rod are respectively hinged to the sliding sleeve and the slider.

[0022] As a further description of the above technical solution:

[0023] The sliding sleeve is threaded with a locking bolt that restricts the relative sliding between the sliding sleeve and the support column.

[0024] As a further description of the above technical solution:

[0025] The slider includes a positioning rod fixedly connected to the slider. The positioning rod is radially distributed along the support column, and the positioning rod is located on the side of the positioning column closer to the GPS locator.

[0026] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0027] During the installation of electromechanical equipment or pipelines, the center of the flange or the center of the pipe end is compared with the actual coordinates of the flange or the pipe end in the 3D model coordinate diagram of the electromechanical equipment and pipelines drawn based on BIM. This allows for the confirmation of the accuracy of the installation position of the electromechanical equipment and pipelines at each step of the construction process, solving the problem of difficulty in confirming the accuracy of the installation position of the installed electromechanical equipment or pipelines at each step of the construction process.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see Figure 1 This invention provides a technical solution: a BIM-based construction method for electromechanical installation in public buildings, comprising the following steps:

[0035] S1. In the BIM-based 3D model coordinate diagram of electromechanical equipment and its pipelines, mark the coordinate points of the flange center of each electromechanical equipment and the coordinate points of the installation end of each electromechanical pipeline based on the coordinate points of the project base point, and import the coordinate point data into the control terminal.

[0036] S2. Install multiple GPS locators 2 at the flange shaft of the electromechanical equipment, and set a unique physical address for each GPS locator 2 in the control terminal so that the unique physical address of each GPS locator 2 corresponds one-to-one with the coordinate address of the GPS locator 2 when the electromechanical equipment is in the final installation position.

[0037] S3. Based on the position difference between the coordinate addresses of multiple GPS locators 2 in the control terminal and the final coordinate address to be installed, the electromechanical device is moved manually or by a transfer device to move multiple GPS locators 2 toward the final coordinate address, so that the coordinate addresses of multiple GPS locators 2 correspond one-to-one with the final coordinate address to be moved.

[0038] S4. Remove the GPS locator 2 from the electromechanical system and clear and reset the address on the GPS locator 2. Then install the GPS locator 2 at the center of the end of the electromechanical pipeline connected to the electromechanical flange. Reset the unique physical address of the GPS locator 2 in the control terminal so that the unique physical address of the GPS locator 2 corresponds one-to-one with the coordinate address of the GPS locator 2 when the electromechanical pipeline is in its final installation position. After connecting the electromechanical pipeline to the electromechanical flange, adjust the installation angle of the electromechanical pipeline so that the coordinate address of the GPS locator 2 corresponds one-to-one with the final coordinate address of its final movement.

[0039] S5. Similarly, based on the installation of electromechanical pipes in S4, complete the installation of subsequent electromechanical pipes until the electromechanical pipes are finally connected with other electromechanical pipes.

[0040] In the BIM-based 3D model coordinate diagram of the electromechanical equipment and its piping, the axis coordinates of each flange of each electromechanical device and the axis coordinates of the installation end of the electromechanical piping are marked. During construction, each GPS locator 2 is installed on the flange axis of different electromechanical devices. A unique physical address is set for each GPS locator 2 in the control terminal, ensuring a one-to-one correspondence between the unique physical address of each GPS locator 2 and the coordinate address of that GPS locator 2 when the electromechanical device is in its final installation position. After the electromechanical device is moved to the designated position manually or by a transport device, the coordinates of each GPS locator 2 installed on the electromechanical device are made to correspond one-to-one with the coordinates of each flange axis of that electromechanical device in the 3D model coordinate diagram, thus completing the installation of the electromechanical device. Based on the installed electromechanical device, the electromechanical piping is aligned with the flange of the electromechanical device, the piping is rotated, the physical position of the GPS locator 2 is cleared and zeroed, and then the GPS locator 2 is installed on the electromechanical device. At the end of the pipeline, the physical address of GPS locator 2 is reset so that its unique physical address corresponds one-to-one with the coordinate address of GPS locator 2 when the electromechanical pipeline is in its final installation position. The installation angle of the electromechanical pipeline is adjusted so that the coordinate address of GPS locator 2 corresponds one-to-one with its final coordinate address for the required movement, thus completing the installation of the electromechanical pipeline. Similarly, subsequent electromechanical pipelines can be installed sequentially. During the installation of electromechanical equipment or pipelines, the flange center or the end center of the pipeline is compared with the actual coordinate position of the flange center or the end center of the pipeline in the 3D model coordinate diagram of the electromechanical equipment and pipelines drawn based on BIM. This allows for the confirmation of the accuracy of the installation position of the electromechanical equipment and pipelines at each step of the construction process, solving the problem of difficulty in confirming the accuracy of the installation position of the installed electromechanical equipment or pipelines at each step of the construction process.

[0041] Specifically, in S3, the control terminal plans the optimal navigation route based on the position difference between the coordinate addresses of multiple GPS locators 2 and the final coordinate address to be installed, thereby achieving the optimal route movement of the electromechanical equipment.

[0042] It can realize the planning of the movement path of electromechanical equipment, thereby improving construction efficiency.

[0043] Specifically, in S5, when the electromechanical pipelines are finally closed, there is no need to install GPS locator 2 in the last installed electromechanical pipeline. The two ends of the electromechanical pipeline can be directly connected to the flanges of the electromechanical or other electromechanical pipelines.

[0044] During the closure phase, assuming no errors occurred in the previous phase, both ends of the electromechanical pipeline are stably connected to the ends of the electromechanical or electromechanical pipeline direct flanges, and can be directly connected through the flanges.

[0045] Specifically, such as Figure 2 As shown, a BIM-based construction method for the electromechanical installation of a public building includes a GPS locator 2, which is detachably installed at the center of the flange of each electromechanical component or at the center of the end of the electromechanical pipe via a positioning component.

[0046] The positioning component allows the GPS locator 2 to be stably and detachably installed at the flange center of each electromechanical component or at the end of the electromechanical pipeline, ensuring stable positioning of the GPS locator 2 at the flange center of each electromechanical component or at the end of the electromechanical pipeline.

[0047] Specifically, such as Figure 2 and Figure 3 As shown, the positioning assembly includes a support column 1 whose end axis is fixedly connected to a GPS locator 2. At least three positioning columns 3 arranged in a circular array are fixedly connected to the end of the support column 1 near the GPS locator 2. Each positioning column 3 has a slider 4 that slides along the axial direction of the positioning column 3. The support column 1 has a sliding sleeve 6 that slides and adjusts along the axial direction of the support column 1. The sliding sleeve 6 is connected to each slider 4 via a connecting rod 7. The two ends of the connecting rod 7 are hinged to the sliding sleeve 6 and the slider 4, respectively. A locking bolt 8 that restricts the relative sliding between the sliding sleeve 6 and the support column 1 is screwed onto the sliding sleeve 6. The slider 4 includes a positioning rod 5 that is fixedly connected to the slider 4. The positioning rod 5 is radially distributed along the support column 1 and is located on the side of the positioning column 3 near the GPS locator 2.

[0048] Slide the sliding sleeve 6 away from the GPS locator 2, thereby driving the slider 4 to slide inward through the connecting rod 7. At this time, move the support column 1 towards the flange or end of the pipe, so that multiple positioning columns 3 are all in contact with the outer wall of the flange or end of the pipe, thereby placing the GPS locator 2 at the end of the flange or pipe. Slide the sliding sleeve 6 towards the GPS locator 2, and drive multiple sliders 4 to expand outward synchronously through the connecting rod 7. Since there are at least three sliders 4 arranged in a circular array, the positioning rods 5 on multiple sliders 4 are synchronously pressed against the inner wall of the pipe or flange. At this time, the GPS locator 2 is located at the axis of the pipe or flange. Then, tighten the locking bolt 8 to press against the support column 1, completing the locking between the sliding sleeve 6 and the support column 1, thereby fixing the GPS locator 2 and the positioning assembly to the pipe or flange.

[0049] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
