Description

Technical Field

[0001] This invention relates to the field of electromechanical installation technology in industrial plant buildings, and more specifically, to a collaborative construction method, system, and medium for pre-assembly of ceiling lighting in industrial plants. Background Technology

[0002] In the construction of large industrial plants, especially steel-structured plants, the ceiling lighting system typically needs to be installed on steel beams or the lower chord of roof trusses at a high location. Currently, the industry generally adopts a sequential construction model, which involves first completing the hoisting and high-altitude welding of the main steel structure of the plant, such as steel columns, steel beams, and purlins. After the main structure forms a stable working platform, construction workers then climb to the height to install the lighting system. This subsequent installation process specifically includes a series of electrical operations at height, such as electrical conduit installation, wiring, fixing of lamp holders and lamps, wiring connection, and debugging.

[0003] However, the traditional "structure first, lighting later" installation method has the following significant drawbacks: First, working at heights carries high risks. Because many electrical procedures, such as piping, wiring, and connection work, must be performed at height, workers are exposed to the risk of falls for extended periods. Although safety platforms and safety harnesses are implemented on construction sites, these measures only reduce the severity of injury in the event of an accident and cannot fundamentally eliminate the danger of workers operating near edges at heights. Furthermore, the safety facilities and management costs invested in ensuring the safety of working at heights significantly increase the overall project cost.

[0004] Secondly, construction efficiency is low and labor costs are high. High-altitude operations are severely affected by weather changes such as strong winds, rain, snow, and other cross-disciplinary construction activities such as equipment hoisting and pipeline installation, making them impossible to carry out continuously and efficiently like ground-based operations. Furthermore, high-altitude operations demand higher levels of skill, physical fitness, and psychological resilience from construction workers, resulting in significantly higher labor costs than ground-based operations. These two factors combined lead to overall low construction efficiency and difficulty in ensuring the project schedule is met.

[0005] Third, construction quality is difficult to control effectively. Laying and connecting pipelines at high altitudes restricts the operator's posture and makes it difficult to establish accurate work benchmarks, easily leading to common quality problems such as uneven pipeline laying, loose pipe joints, and insecure fixing. These quality issues are difficult to detect and rectify in a timely manner under high-altitude conditions, potentially posing safety hazards to the normal operation of the lighting system later.

[0006] Fourth, there is significant overlap and interference with the main structure and other professional construction work. Traditional methods schedule most of the lighting system work after the main steel structure is completed, inevitably leading to time and space conflicts between lighting construction and subsequent equipment installation, interior decoration, and other processes. To avoid safety risks and efficiency losses caused by overlapping work, additional coordination and waiting time is often required, thus extending the overall project construction period.

[0007] To address the aforementioned issues, some improvements have been attempted in existing technologies. For example, luminaires are pre-installed on light poles or brackets on the ground to form semi-finished products, or a dedicated aerial work platform is used for auxiliary installation. However, these solutions do not fundamentally change the sequential construction logic of "installing the lighting system after the main structure is completed." The core installation work of the lighting system still needs to be carried out at high altitude after the structure is hoisted. Summary of the Invention

[0008] In view of this, the present invention proposes a pre-assembled collaborative construction method, system and medium for ceiling lighting in industrial plants, aiming to solve existing problems.

[0009] On one hand, this invention proposes a collaborative construction method for pre-assembly of ceiling lighting in industrial plants. This method includes the following steps: a pre-assembly preparation step, confirming the lighting piping paths, junction box locations, lamp installation points, and pre-assembly unit divisions on each steel structure component; a ground pre-assembly step, where, before hoisting the steel structure components, pre-laying of pipelines, pre-threading of lines, pre-installation of connecting bases, and positioning markings are carried out in the ground work area to complete the lighting pre-assembly on the steel structure components; wherein, the connecting bases are used to connect the lighting fixtures; a collaborative hoisting step, where the pre-assembled steel structure components are hoisted into place and fixed as a whole hoisting unit; and an on-site installation and final connection step, where, after each steel structure component is hoisted into place and fixed, the lighting system is finally connected.

[0010] Furthermore, in the above-mentioned pre-assembly collaborative construction method for ceiling lighting of industrial plants, the pre-assembly preparation step includes the following sub-steps: steel modeling sub-step, modeling the main steel beams, purlins, stiffening plates, and hoisting lugs in Tekla Structures, and dividing each purlin into pre-assembly units to obtain the steel structure reference model; The lighting modeling sub-step involves creating JDG conduit parametric families, lighting cable parametric families, and connection base parametric families in Revit, and modeling the lighting system based on the steel structure baseline model. The lighting system model includes conduit models, luminaire models, and connection base models. The model integration sub-step imports the steel structure baseline model and lighting system model into Navisworks for integrated integration, performing full-dimensional hard and soft collision detection to eliminate interference between conduits, connection bases, steel structure components, and hoisting parts, thus forming a unified zenith lighting model. The pre-simulation sub-step performs 4D construction simulation on the unified zenith lighting model to verify the feasibility of the entire process of ground pre-assembly, collaborative hoisting, and on-site termination. The output sub-step outputs unified pre-assembly construction drawings, a processing list, unit identification diagrams, and visual handover documents, determining the lighting conduit paths, junction box locations, luminaire installation points, and pre-assembly unit divisions on each steel structure component.

[0011] Furthermore, in the above-mentioned collaborative construction method for pre-assembly of ceiling lighting in industrial plants, the ground pre-assembly step includes the following sub-steps: a pipeline pre-laying sub-step, where, based on the lighting piping path determined in the pre-assembly preparation step, cable protection pipes are fixed to the steel structure components, with threaded joints or clamps connecting the pipes; a line pre-threading sub-step, where lighting cables or traction steel wires are pre-threaded into the protection pipes, with a preset length reserved at both ends, and cable markings are made; a connection base pre-installation sub-step, where, based on the lamp installation points determined in the pre-assembly preparation step, connection bases are initially installed at the lamp installation points; and a positioning and marking sub-step, where the hoisted orientation, number, and interface correspondence with adjacent lighting units are marked on the steel structure components.

[0012] Furthermore, in the aforementioned pre-assembly collaborative construction method for ceiling lighting in industrial plants, the on-site installation and final connection steps include the following sub-steps: a modular luminaire installation sub-step, in which matching modular luminaires are fixed to the base body of the connecting base through a locking mechanism on the connecting base, and the plug-in connection with the terminals on the connecting base is completed; a unit-to-unit wiring connection sub-step, in which the cables reserved by adjacent pre-assembly units are connected through a waterproof and dustproof junction box at the nodes of the pre-assembly units to achieve circuit continuity; and a system testing and debugging sub-step, in which insulation resistance testing, circuit power-on testing, luminaire lighting debugging, and illuminance testing are performed.

[0013] Another invention proposes a collaborative construction system for pre-assembly of ceiling lighting in industrial plants, comprising: a pre-assembly preparation module for confirming the lighting piping paths, junction box locations, lamp installation points, and pre-assembly unit divisions on each steel structure component; a ground pre-assembly module for pre-laying pipelines, pre-threading lines, pre-installing connecting bases, and marking positions in the ground work area before hoisting the steel structure components, so as to complete the lighting pre-assembly on the steel structure components; wherein, the connecting base is used to insert lighting fixtures; a collaborative hoisting module for hoisting and fixing the pre-assembled lighting steel structure components as a whole hoisting unit; and an on-site installation and termination module for terminating the lighting system after each steel structure component has been hoisted and fixed.

[0014] Furthermore, the aforementioned collaborative construction system for pre-assembled ceiling lighting in industrial plants includes a pre-assembly preparation module comprising: a steel modeling submodule, used to model the main steel beams, purlins, stiffening plates, and hoisting lugs in Tekla Structures, and to divide individual purlins into pre-assembly units to obtain a steel structure baseline model; a lighting modeling submodule, used to create JDG pipe parametric families, lighting cable parametric families, and connection base parametric families in Revit, and to model the lighting system model based on the steel structure baseline model; wherein the lighting system model includes a piping model, a luminaire model, and a connection base model; and a model integration submodule, used to import the steel structure baseline model and the lighting system model into Navisworks. The system integrates and conducts full-dimensional hard and soft collision detection to eliminate interference between pipelines, connecting bases, steel structure components, and hoisting parts, forming an integrated zenith lighting model. The pre-simulation submodule is used to perform 4D construction simulation on the integrated zenith lighting model to verify the feasibility of the entire process of ground pre-assembly, collaborative hoisting, and on-site termination. The output submodule is used to output integrated pre-assembly construction drawings, processing lists, unit identification diagrams, and visual handover documents, determining the lighting piping paths, junction box locations, lamp installation points, and pre-assembly unit divisions on each steel structure component.

[0015] Furthermore, in the aforementioned collaborative construction system for pre-assembly of ceiling lighting in industrial plants, the ground pre-assembly module includes: a pipeline pre-laying sub-module, used to fix cable protection pipes to steel structure components based on the lighting piping path determined in the pre-assembly preparation steps, with threaded joints or special clamps connecting the pipes; a line pre-threading sub-module, used to pre-thread lighting cables or traction steel wires into the protection pipes, leaving a preset length at both ends and marking the cables; a connection base pre-installation sub-module, used to initially install connection bases at the lighting fixture installation points determined in the pre-assembly preparation steps; and a positioning and marking sub-module, used to mark the hoisted orientation, number, and interface correspondence with adjacent lighting units on the steel structure components.

[0016] Furthermore, in the aforementioned pre-assembled collaborative construction system for ceiling lighting in industrial plants, the on-site installation and termination module includes: a modular luminaire installation sub-module, used to fix the matching modular luminaires to the base body of the connecting base through a locking mechanism on the connecting base, and to complete the plug-in connection with the wiring terminals on the connecting base; an inter-unit wiring connection sub-module, used to connect the cables reserved in adjacent pre-assembled units at the nodes of the pre-assembled units through a waterproof and dustproof junction box to achieve circuit continuity; and a system testing and debugging sub-module, used to perform insulation resistance testing, circuit power-on testing, luminaire lighting debugging, and illuminance testing.

[0017] In another aspect, the present invention also provides a computer-readable storage medium storing a computer program for performing the methods described in any of the above aspects.

[0018] In another aspect, the present invention also proposes an electronic device comprising: a processor; a memory for storing executable instructions of the processor; the processor being configured to read the executable instructions from the memory and execute the instructions to implement the method described in any of the preceding aspects.

[0019] The present invention provides a pre-assembly collaborative construction method, system, and medium for industrial plant ceiling lighting, which revolutionizes the traditional sequential process of "structural completion → high-altitude lighting construction" (i.e., "high-altitude lighting construction after structural completion") into a parallel collaborative process of "structural ground pre-assembly → collaborative hoisting → ground final connection" (i.e., "structural ground pre-assembly, collaborative hoisting, and ground final connection"). This transfers more than 80% of the workload for high-altitude operations, such as piping and wiring, to safe and efficient ground completion. As a result, the proportion of high-altitude operation time for lighting construction in the plant is reduced from about 70% in the traditional method to less than 15%, with the main high-altitude operation being only the final hanging and plugging of the lamps. At the same time, by setting up a pre-assembly connection base with integrated load-bearing fixing, electrical connection, and anti-misinsertion guidance functions, a standardized interface module is formed, realizing plug-and-play of lamps and simplifying high-altitude operations to hanging and plugging operations. This construction method fundamentally reduces the exposure time and labor intensity of construction workers at dangerous heights, lowers the risk of safety accidents such as falls and electric shocks, and significantly improves work efficiency through ground-based assembly line operations, saving on high-altitude operation measures and labor costs. The overall construction cost can be reduced by 30% to 40%. In addition, the good ground pre-assembly environment is conducive to ensuring the construction quality such as horizontal and vertical piping and tight joints. The standardized joints also provide great convenience for the later replacement and maintenance of lighting fixtures. Attached Figure Description

[0034] Method Implementation Examples: See Figure 1 This is a flowchart illustrating the pre-assembly and collaborative construction method for ceiling lighting in industrial plants provided in this embodiment of the invention. As shown in the figure, the construction method includes the following steps: Pre-assembly preparation step S1: Confirm the lighting piping path, junction box location, lamp installation point, and pre-assembly unit division on each steel structure component.

[0035] Specifically, BIM can be used first for the coordinated and detailed design of lighting and steel structure construction, resulting in detailed lighting and steel structure construction drawings. In particular, a joint design team should be formed, encompassing steel structure detailing, lighting and electrical systems, construction technology, prefabrication, and hoisting operations. This collaborative detailing design should be conducted using the integrated BIM platform of Tekla Structures + Revit + Navisworks: using the factory's grid lines, elevations, and coordinate systems as a unified benchmark, and achieving seamless interoperability of professional models through the IFC international standard format. Based on the detailed lighting and steel structure construction drawings, the lighting piping paths, junction box locations, lamp installation points, and pre-assembly unit divisions on each steel structure component should be determined. The steel structure components include main steel beams, secondary beams, and purlins.

[0036] In ground pre-assembly step S2, before the steel structure components are hoisted, pipelines are pre-laid, lines are pre-threaded, connecting bases are pre-installed, and positioning marks are made in the ground work area to complete the lighting pre-assembly on the steel structure components; among them, the connecting base is used to plug in the lighting fixtures.

[0037] Specifically, before the steel structure components are hoisted, the following work is completed in the ground work area: pre-laying of pipelines, i.e., JDG pipe 3, pre-threading of lines, pre-installation of connecting base 2, and positioning marking, such as... Figure 2 As shown, the standardized interface module design is achieved through the connecting base 2, which integrates load-bearing fixation, electrical connection, and anti-misinsertion guidance functions, realizing the "plug and play" of the lamps. This simplifies high-altitude operations to a simple lamp hanging and plugging / unplugging operation, greatly shortening the high-altitude operation time.

[0038] In the collaborative hoisting step S3, the steel structure component that has completed the pre-assembly of lighting is hoisted into place and fixed as a whole hoisting unit.

[0039] Specifically, pre-assembled steel structure components for lighting are hoisted as a whole unit, and hoisted, positioned, aligned, and fixed according to steel structure hoisting procedures. Tracked hoisting can be used. During hoisting, temporary protective measures are taken for the pre-installed lighting conduits and interfaces, and flexible sheaths can be used to protect exposed base interfaces. After the purlins are in place, they are bolted or welded for fixation.

[0040] Step S4 involves terminating the lighting system after all steel structure components have been hoisted into place and secured.

[0041] Specifically, after all purlins are installed, construction workers use a mobile lifting platform to align the lighting fixtures with the connecting base 2 and plug them into the connecting base 2, achieving mechanical shortening and automatic connection of electrical plugs. At the intersection of the main and secondary roof beams, an IP65-rated junction box 4 is installed. Cables from adjacent purlin units (i.e., pre-assembled units 1) are led into the box and connected in parallel via terminal blocks. Figure 3 As shown. After everything is completed, perform system debugging.

[0042] See Figure 4 This is a flowchart of the pre-assembly preparation step provided in an embodiment of the present invention. As shown in the figure, the pre-assembly preparation step S1 includes the following sub-steps: In the steel modeling sub-step S11, the main steel beams, purlins, stiffening plates, and hoisting lugs are modeled in Tekla Structures, and each purlin is divided into pre-assembly units to obtain the steel structure baseline model.

[0043] Specifically, each purlin is divided into pre-assembly unit 1, and the main steel beam, purlin, stiffening plate, and hoisting lug are modeled with high precision at LOD400 in Tekla Structures to obtain the steel structure reference model.

[0044] In the lighting modeling sub-step S12, a JDG pipe parametric family, a lighting cable parametric family, and a connection base parametric family are created in Revit. Based on the steel structure baseline model, the lighting system model is modeled. The lighting system model includes a piping model, a luminaire model, and a connection base model.

[0045] Specifically, in Revit, parametric families such as JDG pipes, lighting cables, and pre-assembled connection bases 2 are created. Based on the steel structure reference model, the piping path planning, the three-dimensional coordinate calibration of the luminaire installation points, and the base interface layout design are completed to obtain the lighting system model.

[0046] In the model integration sub-step S13, the steel structure reference model and the lighting system model are imported into Navisworks for integrated integration. Hard and soft collision detection is carried out in all dimensions to eliminate interference between pipelines, connecting bases and steel structure components and hoisting parts in a closed loop, thus forming an integrated zenith lighting model.

[0047] Specifically, the two models are imported into Navisworks for integrated processing, enabling full-dimensional detection of hard and soft collisions, and closed-loop elimination of interference issues between pipelines, bases, steel structure components, and hoisting parts.

[0048] In the pre-simulation sub-step S14, a 4D construction simulation is performed on the integrated zenith lighting model to verify the feasibility of the entire process of ground pre-assembly, collaborative hoisting, and on-site final connection.

[0049] Specifically, the pre-assembly unit 1 was further solidified, the base parameters were calibrated, the pipeline fixing scheme was optimized, and the identification system was designed. The feasibility of the entire process of ground pre-assembly, collaborative hoisting, and on-site final connection was verified through 4D construction simulation.

[0050] Output sub-step S15, output integrated pre-assembly construction drawings, processing list, unit identification diagram and visual handover documents, and determine the lighting piping path, junction box location, lamp installation point and pre-assembly unit division on each steel structure component.

[0051] Specifically, the final output includes integrated pre-assembled construction drawings, a processing list, unit identification diagrams, and visual handover documents. Based on the above BIM collaborative deepening results, the path of the 20mm diameter JDG conduit, the locations of two junction boxes, and the coordinates of four lighting fixture installation points are clearly defined for each unit. The connecting base 2 includes: a base body, terminals mounted on the connecting base 2, and a locking mechanism mounted on the connecting base 2. The locking mechanism is used to lock the lighting fixtures and can be a three-claw rotating snap-fit ​​structure, or other structures such as rotating snap-fits or bolts. In this embodiment, the pre-assembled connecting base 2 can be fixed to the purlin web plate with two M10 high-strength bolts. The upper part is equipped with a six-pin waterproof plug socket with a foolproof key. The mechanical part is a three-claw rotating snap-fit ​​locking mechanism, which enables "plug-and-play" operation of the lighting fixtures, simplifying high-altitude work to simple lamp hanging and plugging / unplugging operations, greatly reducing high-altitude work time.

[0052] See Figure 5 This is a flowchart of the ground pre-assembly step provided in an embodiment of the present invention. As shown in the figure, the ground pre-assembly step S2 may include the following sub-steps: In the pipeline pre-laying sub-step S21, based on the lighting piping path determined in the pre-assembly preparation step, the cable protection pipe is fixed to the steel structure component, and the pipes are connected by threaded joints or clamps.

[0053] Specifically, in the steel structure processing plant or on-site ground prefabrication yard, the purlins are placed horizontally; first, based on the lighting piping path determined in the pre-assembly preparation steps, the JDG pipe 3, i.e. the cable protection pipe, is fixed to the lower flange of the purlin using pipe clamps as shown in the figure, and the pipes are connected by threaded joints or special clamps.

[0054] In step S22, the lighting cable or traction wire is pre-threaded into the protective tube, with a preset length reserved at both ends, and the cable is marked.

[0055] Specifically, the lighting cable or traction wire is pre-threaded into the protective conduit, for example, an RVV-3x2.5 lighting cable can be threaded in. A preset length is reserved at both ends of the lighting cable, and the cable is clearly marked. The preset length can be determined according to actual conditions; this embodiment does not impose any limitations on it.

[0056] In the pre-installation sub-step S23 of the connecting base, the connecting base is initially installed at the lamp installation point based on the lamp installation point determined in the pre-assembly preparation step.

[0057] Specifically, at the designed lighting fixture mounting points, pre-assembled connection bases 2 are installed and can be fixed to the purlins with bolts. For example, pre-assembled connection bases 2 are installed at four mounting points, and the corresponding wire cores of the cable are connected to the terminals inside the base.

[0058] In the positioning and marking sub-step S24, the orientation, number, and interface correspondence with adjacent lighting units are marked on the steel structure components after hoisting.

[0059] Specifically, mark the orientation, number, and interface correspondence with adjacent lighting units in a prominent position on the component after hoisting. For example, use eye-catching paint to mark "Lighting Unit - Number" and directional arrows at both ends of the purlin to indicate the installation direction.

[0060] See Figure 6 This is a flowchart of the on-site installation and termination steps provided in an embodiment of the present invention. As shown in the figure, the on-site installation and termination step S4 includes the following sub-steps: In the modular lighting installation sub-step S41, the matching modular lighting fixture is fixed to the base body of the connecting base through the locking mechanism on the connecting base, and the plug-in connection with the wiring terminals on the connecting base is completed.

[0061] Specifically, after all the purlins are installed, the construction workers use a mobile lifting platform to align the LED industrial and mining lamps with the base and rotate them about 60 degrees to complete the mechanical locking. At the same time, the electrical plugs are automatically connected.

[0062] In the inter-unit wiring connection sub-step S42, at the pre-assembled unit node, the cables reserved by the adjacent pre-assembled units are connected through a waterproof and dustproof junction box to achieve circuit continuity.

[0063] Specifically, at the intersection of the main beam and the secondary beam of the roof, a junction box 4 with an IP65 protection rating is installed to bring the cables of the adjacent purlin units into the box and complete the parallel connection through the terminal block.

[0064] System testing and debugging sub-step S43 involves performing insulation resistance testing, circuit power-on testing, lamp lighting debugging, and illuminance testing.

[0065] Specifically, insulation resistance testing, circuit power-on testing, lamp lighting debugging, and illuminance testing are conducted.

[0066] In summary, the pre-assembly collaborative construction method for industrial plant ceiling lighting provided in this embodiment revolutionizes the traditional sequential process of "structural completion → high-altitude lighting construction" (i.e., "high-altitude lighting construction after structural completion") into a parallel collaborative process of "structural ground pre-assembly → collaborative hoisting → ground final connection" (i.e., "structural ground pre-assembly, collaborative hoisting, and ground final connection"). This transfers more than 80% of the workload for high-altitude operations, such as piping and wiring, to safe and efficient ground-based completion. Consequently, the proportion of high-altitude operation time for lighting construction in this plant is reduced from approximately 70% in the traditional method to less than 15%, with the main high-altitude operation being only the final connection and plugging of the lamps. At the same time, by setting up a pre-assembly connection base 2 that integrates load-bearing fixation, electrical connection, and anti-misinsertion guidance functions, a standardized interface module is formed, enabling plug-and-play functionality for the lamps and simplifying high-altitude operations to connection and plugging operations. This construction method fundamentally reduces the exposure time and labor intensity of construction workers at dangerous heights, lowers the risk of safety accidents such as falls and electric shocks, and significantly improves work efficiency through ground-based assembly line operations, saving on high-altitude operation measures and labor costs. The overall construction cost can be reduced by 30% to 40%. In addition, the good ground pre-assembly environment is conducive to ensuring the construction quality such as horizontal and vertical piping and tight joints. The standardized joints also provide great convenience for the later replacement and maintenance of lighting fixtures.
