Description

Technical Field

[0001] The present invention belongs to the technical field of building steel structure installation, and particularly relates to an auxiliary installation device and an installation method for a large overhanging inclined steel structure. Background Art

[0002] In recent years, with the increasing requirements for the use function and architectural aesthetics of high-rise buildings, the structural forms of high-rise buildings have become more diverse, such as plane irregular buildings, buildings with transfer floors, vertically retracted and overhanging buildings, etc. In particular, the overhanging structure is widely used in the design of the podium of high-rise buildings due to its advantages of full utilization of space resources, less occupation of land resources, large visual impact, and strong architectural artistry.

[0003] Since steel has the advantages of high strength, high stiffness, good plasticity, light self-weight, and resistance to dynamic loads, it has become the preferred material for overhanging structures. However, the high-position large overhanging steel structure is restricted by various aspects such as site conditions, lifting equipment, structural safety, and construction costs. In particular, the high-position large overhanging inclined steel structure brings great difficulties to the specific construction.

[0004] Currently, when installing an overweight, extra-long and inclined overhanging structure, the method of hoisting and splicing multiple sections is usually adopted. However, since the overhanging is inclined, it is difficult to control the angle of the crane hoisting the steel structure (due to shaking or its own hoisting reasons), and it is difficult to ensure the alignment and positioning effect of the splicing end of the steel structure in the inclined state, that is, it is difficult to guarantee the installation accuracy. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide an auxiliary installation device and an installation method for a large overhanging inclined steel structure, so as to solve the problem that when splicing and installing an inclined overhanging structure, due to the difficult control of the inclination angle of the hoisted steel structure, the alignment effect at the splicing part is poor, resulting in difficult guarantee of the installation accuracy.

[0006] To achieve the above purpose, the present invention provides the following technical solutions:

[0007] An auxiliary installation device and installation method for a large overhanging inclined steel structure of the present invention are used for aligning the splicing ends of adjacent steel structures, and include two sets of hoop mechanisms and several sets of traction mechanisms. The two sets of hoop mechanisms are respectively used for surrounding and fixing on the two splicing ends of adjacent steel structures, and several through grooves that are circumferentially distributed and penetrate are provided on the outer side surfaces of the two sets of hoop mechanisms. One set of traction mechanism includes two traction blocks, a flexible traction rope and a jacking component. The two traction blocks are respectively fixed on the outer side surfaces of the two sets of hoop mechanisms. The flexible traction rope passes through the two traction blocks, and one end of the flexible traction rope is connected to the end of the flexible traction rope in a limiting manner, and the other end is connected to the output end of the jacking component, and the fixed end of the jacking component is connected to the hoop mechanism on this side. The several sets of traction mechanisms are circumferentially distributed on the outer side surfaces of the two sets of hoop mechanisms.

[0008] Further, the hoop mechanism includes a hoop. Several circumferentially distributed mounting brackets are provided on the outer side surface of the hoop. Tightening components are provided on the mounting brackets. The output ends of the tightening components pass through the hoop and are located inside the hoop. Tightening blocks are provided on the output ends of the tightening components. The through grooves, the jacking component and the traction blocks are all arranged on the hoop.

[0009] Further, an alignment component is also provided on the hoop. The alignment component includes an alignment flat plate. Clamping blocks that match the through grooves are provided on the edge of the alignment flat plate.

[0010] Further, several circumferentially distributed locking components are also provided on the edge of the alignment flat plate. The locking components include locking sliding rods, locking springs and stoppers. The locking sliding rods are slidably arranged perpendicular to the alignment flat plate. One end of the locking spring is fixed to the end of the locking sliding rod, and the other end is fixed to the alignment flat plate. The stoppers are perpendicularly fixed to the other ends of the locking sliding rods, and the stoppers and the clamping blocks are arranged on the same side of the hoop.

[0011] Further, both the jacking component and the tightening component adopt hydraulic components.

[0012] Further, the end of the traction block is flush with the side surface of the hoop.

[0013] Further, the flexible traction rope is a steel wire rope.

[0014] In order to further improve the installation accuracy, the present technical solution also discloses an installation method for a large overhanging inclined steel structure, including the following steps:

[0015] Step 1: BIM model construction; in the early stage, through the planning stage, the resources required during the installation process are counted, including component models, component weights, installation times and costs, etc.; at the same time, feasible installation schemes are analyzed and a BIM model is constructed, and various resources are assigned to the model to construct a second model that combines virtual and actual.

[0016] Step 2: Model installation deduction: Select a feasible installation plan, and obtain at least three installation methods for high-position large cantilever inclined steel structures through relevant data search and related technical deduction;

[0017] Step 3: Installation model "collision": Through the several installation methods selected above, the BIM full model is constructed, including the settings of load, installation form, installation path, installation environment, etc. After the settings are completed, simulation calculations are performed one by one to analyze whether the installation requirements are met through the simulation results. If the actual installation requirements on site are not met due to some reasons, corrective measures such as adjusting parameters are taken, and optimization is repeated to finally obtain the installation model. Each scheme is subjected to model "collision" one by one in the above manner to obtain a preliminary optimized installation model. If the installation model does not meet the requirements and is too far away from the original scheme target, it is discarded;

[0018] Step 4: Installation model optimization: After obtaining the installation plan after the initial "collision", "collision" is carried out again, and each plan is compared again. The comparison and analysis scope includes the practicality of on-site implementation, installation method, measure cost, time factor and other aspects. The analysis and comparison of various influencing factors are carried out, and finally an optimal plan with strong practicality, low measure cost and short construction period is obtained;

[0019] Step 5: Reproduce the installation model; reproduce the optimization plan with the model, prepare components, installation equipment, personnel, etc. according to the plan, and guide the on-site construction through the optimization model replication;

[0020] Step 6: Real-time interaction of the installation model: During on-site construction, by setting up monitoring information points and using relevant monitoring equipment to interconnect with the BIM platform, monitoring information such as structural force, coordinate points, environmental parameters, etc., can be displayed in real time in the BIM installation model, making the installation process status clear at a glance and the installation construction status real-time;

[0021] Step 7: Interactive model feedback: Based on the monitoring information points set above, the information of each monitoring point is obtained. The monitoring information allows the installer to fully understand the installation status, but it is impossible to immediately perceive whether the installation is carried out according to the predetermined installation target. Therefore, early warning threshold measures are taken to address this problem, so that the interactive model can quickly provide feedback and reflect the installation progress information, installation deviation information, installation adjustment information, etc. in a timely manner;

[0022] Step 8: Real-time dynamic adjustment: Based on the aforementioned interactive model feedback information, risk identification is performed through color gradation display or warning information output, and the on-site installation status is dynamically adjusted in a timely manner. Key items are continuously monitored, and real-time dynamic adjustments are continuously performed based on the interactive model feedback information until the installation is completed.

[0023] The beneficial effects of the present invention are:

[0024] (1) This technical solution can align the two ends of the steel structure splicing part by pulling. During the pulling process, the flexible pulling rope will be stretched straight, and the positions of the two ends will be gradually adjusted during the stretching process, and eventually the two pulling blocks on the same pulling rope will be in a straight line. At this time, the side surfaces of the two clamping mechanisms are in contact and aligned, thereby realizing the alignment of the two ends of the steel structure splicing;

[0025] (2) Due to its softness, the flexible traction rope can be connected to the two ends of the steel structure that are staggered or inclined. That is, when the device is initially installed, there is no need to use a crane to adjust the end position of the steel structure. That is, the device has low requirements for the accuracy of crane hoisting.

[0026] (3) The setting of the through groove cleverly enables the device to perform initial local welding and fixing of the joint through the through groove after aligning the two ends of the steel structure. Such a setting greatly simplifies the complexity of the positioning device;

[0027] (4) Establishing a BIM model and obtaining the optimal installation solution for high-position large cantilevered inclined steel structures through a double “collision” iteration method, which has high reliability; this method establishes a BIM model, performs “collision” iterations before and during construction, continuously optimizes the installation method, and ensures the installation positioning accuracy and installation quality of the steel structure during on-site implementation;

[0028] (5) Save installation costs and rationally allocate resources. The BIM model is used to achieve full resource integration of high-position large-scale cantilevered inclined steel structures. On the one hand, it ensures the optimal installation and positioning of the steel structure, and on the other hand, it ensures the maximum utilization of resources. Compared with traditional installation methods, it reduces unnecessary measures and costs, thus saving installation costs overall and rationalizing resource utilization.

[0029] (6) Use the real-time visual interaction model (3M2I model) and the installation feedback mechanism is fast. Through the Internet of Things, the real-time visualization of the interaction between the on-site installation and the BIM model is realized, the implementation deviation of the installation process is grasped in real time, and feedback is quickly given and adjustments are made in time during the construction process to ensure that the installation of high-level large-scale cantilevered inclined steel structures is implemented according to the optimal solution.

Detailed implementation manners

[0044] As Figures 1-8 shown, an auxiliary installation device and installation method for a large cantilever inclined steel structure of the present invention are used for aligning the splicing ends of adjacent steel structures. It should be noted in advance that as shown in the attached Figure 1As shown in the figure, when the large overhang is installed, due to its long length, it is formed by splicing multiple sections of steel structures and then welding and fixing them. Therefore, for further understanding, the large overhang is divided into a fixed steel structure 2 and several spliced steel structures 3. One end of the fixed steel structure 2 is fixed to the foundation building 1, and the other end is connected and fixed to the spliced steel structure 3. On this basis, this splicing positioning device includes two sets of hoop mechanisms and several sets of traction mechanisms. The purpose of the two sets of hoop mechanisms is to be fixed to both ends of the steel structure at the splicing point, and the role of the traction mechanism is to tighten and fit the two sets of hoop mechanisms through traction, so as to align and fit the two ends at the splicing point.

[0045] Specifically, the two sets of hoop mechanisms are respectively used to surround and fix on the two splicing ends of adjacent steel structures, and there are several through slots 11 that are evenly distributed in a circle and penetrate through on the outer side surfaces of the two sets of hoop mechanisms. The purpose of setting the through slots 11 here is to facilitate the welding rod to enter from the through slots 11 to perform local welding on the end of the steel structure after splicing. After welding, this device can be disassembled, and then a comprehensive welding operation can be carried out. This way can greatly simplify the welding difficulty. At the same time, the method of setting the through slots 11 can make the edges of the hoop mechanisms contact and align, which can improve the alignment effect of the ends of the steel structure. Among them, one set of traction mechanism includes two traction blocks 8, a flexible traction rope 9 and a jacking component 10. The two traction blocks 8 are respectively fixed on the outer side surfaces of the two sets of hoop mechanisms. The flexible traction rope 9 passes through the two traction blocks 8, and one end of the flexible traction rope 9 is connected to the end limit of the flexible traction rope 9, and the other end is connected to the output end of the jacking component 10, and the fixed end of the jacking component 10 is connected to the hoop mechanism on this side. Several sets of traction mechanisms are evenly distributed in a circle on the outer side surfaces of the two sets of hoop mechanisms.

[0046] As Figures 1-3As shown in the figure, the schematic diagram of the installation of this device at the ends of the fixed steel structure 2 and the spliced steel structure 3. Specifically, the hoop mechanism includes a hoop 4. A number of mounting brackets 5 are evenly distributed in a circle on the outer side of the hoop 4. The mounting brackets 5 are fixed on the outer side of the hoop 4. Tightening components 6 are provided on the mounting brackets 5. The output ends of the tightening components 6 pass through the hoop 4 and are located inside the hoop 4. Tightening blocks 7 are provided on the output ends of the tightening components 6. The shape of the tightening blocks 7 can be determined according to the shape of the steel structure. In this specific embodiment, the steel structure is a steel pipe. Therefore, the shape of the tightening blocks 7 is preferably an arc-shaped block, and a rubber anti-slip layer should be provided on the contact surface with the steel structure, which can improve the contact locking effect between the tightening blocks 7 and the steel structure. Specifically, the through slots 11, the jacking components 10, and the traction blocks 8 are all provided on the hoop 4. The working steps of the hoop mechanism are as follows: First, the hoop 4 is sleeved on the fixed steel structure 2 and the spliced steel structure 3. Then, through the action of the tightening components 6, the output ends of the tightening components 6 are tightened against the outer side of the steel structure, thereby realizing the fixing operation. It is not difficult to understand that a limit block should be provided at one end of the flexible traction rope 9 to prevent the steel wire rope from slipping out of the traction block 8.

[0047] As Figures 4-6 shown in the figure, this drawing is a schematic diagram of the splicing positioning device aligning the ends of the fixed steel structure 2 and the spliced steel structure 3. Specifically, through the action of the jacking assembly, the flexible traction rope 9 is pulled, that is, the hoop mechanism on the spliced steel structure 3 will be pulled closer to another hoop mechanism. When the two are close, the alignment of the splicing ends is achieved. After alignment, local welding is carried out. After welding, when disassembling this device, it can be slid out from the other end of the spliced steel structure 3. It is not difficult to understand that if the hoop 4 is set in a detachable connection mode of two arc parts, the difficulty of disassembly can be further improved.

[0048] As Figure 7 and Figure 8 shown in the figure, preferably, an alignment assembly is also provided on the hoop 4. The alignment assembly includes an alignment flat plate 12. A clamping block 16 matching the through slot 11 is provided on the edge of the alignment flat plate 12. The clamping block 16 is clamped and installed in the through slot 11. At this time, the alignment flat plate 12 is in contact with the side of the hoop 4. That is, when adjusting the position of the hoop 4, it is only necessary to abut the alignment flat plate 12 against the end of the steel structure. After abutment, the hoop 4 can be fixed. Then, the edge of the fixed hoop 4 is flush with the edge of the end of the steel structure. That is, when the two hoops 4 are in contact, the two ends of the steel structure at the splicing part also just touch, that is, the gap is small, which is convenient for subsequent welding operations.

[0049] The edge of the flush plate 12 is also provided with a number of locking components evenly distributed around the circumference, the locking components including a locking slide bar 13, a locking spring 14 and a stopper 15, the locking slide bar 13 is slidably arranged perpendicular to the flush plate 12, one end of the locking spring 14 is fixed to the end of the locking slide bar 13, and the other end is fixed to the flush plate 12, the stopper 15 is vertically fixed to the other end of the locking slide bar 13, and the stopper 15 and the clamping block 16 are arranged on the same side of the holding ring 4. After the flush plate 12 is installed, the locking slide bar 13 is pulled so that the stopper 15 at its end contacts the side of the holding ring 4, so that the flush plate 12 can be locked to the side of the holding ring 4, which is convenient for workers to operate and adjust the position of the holding ring 4, and the flush plate 12 will not be detached, and the hands of the operator can be freed.

[0050] The lifting component 10 and the clamping component 6 are both hydraulic components. Specifically, the lifting component 10 adopts a hydraulic jack, and the end of the wire rope is anchored on its output end, specifically an anchor cup component, and the clamping component 6 can be implemented by a hydraulic push rod.

[0051] The end of the traction block 8 is set flush with the side of the holding ring 4. The advantage of the flush setting is that the flexible traction rope 9 will be straightened when subjected to force, so that the end of the traction block 8 can be aligned. After alignment, the traction block 8 can better guide the flexible traction rope 9, further improving the alignment accuracy. Preferably, the flexible traction rope 9 is a steel wire rope. The purpose of using the flexible traction rope 9 is that due to the inclined cantilever, it is difficult to ensure that the two ends of the splicing are aligned in the inclined direction during crane hoisting. Because in order to align the ends, the crane must tilt the steel structure. During tilt hoisting, it is difficult to control the hoisting angle under the limit of shaking or the movement accuracy of the crane itself, that is, the two ends will be staggered. The steel wire rope is relatively soft, so it can achieve a staggered connection, that is, the hoop mechanism can be installed on the two ends of the steel structure splicing, and when the steel wire rope is tightened under force, the staggered two ends can be pulled to a flush and aligned state. If a rigid component is used, it is difficult to achieve the above effect.

[0052] like Figure 9 and Figure 10As shown in the figure, the object of the present invention is to overcome the deficiencies of the prior art. In order to further improve the installation accuracy of the steel structure cantilever, in this specific embodiment, a method for installing a large cantilever inclined steel structure is also proposed. This method can comprehensively rehearse the installation process of the high-position large cantilever inclined steel structure, determine the installation plan in the early stage of installation, and conduct review and dynamic adjustment during the installation process. Through modules such as the model establishment module, installation collision module, real-time information monitoring module, etc., from the installation model deduction, installation model collision, installation model optimization, installation model reproduction, installation model real-time interaction, interactive model feedback, real-time dynamic adjustment to installation completion; this method solves the problem of difficult installation of high-position (more than 100m) large cantilever inclined steel structures, and at the same time ensures the installation positioning accuracy and ensures the smooth performance of the project.

[0053] To achieve the above object, the present invention is implemented according to the following technical solutions:

[0054] It includes a model establishment module (Model Building), an installation collision (Mounting Collision) module, a real-time information monitoring (Real-time Information Monitoring) module, an interactive information integration (Interactive Information Integration) module, an installation feedback (Installation Feedback) module, etc.; this method selects the optimal installation plan through the early model establishment and installation "collision", and conducts "collision" adjustment during the actual installation process to complete the leap from "paper" to reality. From the establishment of the early model resources to the installation positioning of the steel structure in the later stage, the installation iteration of the high-position large cantilever inclined steel structure is completed in the form of double "collision", and finally the optimal installation method is obtained to complete the installation positioning of the steel structure.

[0055] In an implementable manner, the model establishment module includes model establishment software such as REVIT, and the model is established according to the actual situation of on-site installation. The established model includes project information, the shape of the steel components to be installed and positioned, the amount of installation component resources, installation time, etc.

[0056] In an implementable manner, the installation collision module includes Tekla, Navisworks, 3D Max, etc. Installation collision includes external collision and internal collision. For external collision, the model is imported into Navisworks for collision detection to exclude collisions with structures, mechanical and electrical pipelines; for internal collision, the model established by BIM is imported into Tekla for deepening, and then the model completed by Tekla is imported into 3D Max. The pre-installation simulation of the high-position large cantilever inclined steel structure is carried out through 3D Max, and different installation methods are selected for simulation; through the mutual collision between each scheme, the strength, stress, installation details and rationality of the steel structure are verified, and finally the optimal installation scheme is obtained.

[0057] In an implementable manner, the real-time information monitoring module includes monitoring devices, etc. The monitoring devices are installed at the steel structure installation range to monitor information such as the dynamic position of the steel structure installation in real time; this module is connected to the Internet of Things.

[0058] In an implementable manner, the interactive information integration module includes Internet of Things technology, LoRa technology, etc. The Internet of Things technology is used to collect data added during the construction progress and spatial state monitoring data, and the LoRa technology is used for network transmission to update the BIM construction model in real time and realize an interactive model that combines virtual and real.

[0059] In an implementable manner, the installation feedback module includes technologies such as feature parameter marking, feature parameter deviation independent display, important node tracking, and feature parameter feedback.

[0060] In an implementable manner, the feature parameter marking technology selects physical feature parameters during the installation process, such as special point coordinates, mechanical properties, etc., and grasps the required point information in real time through feature parameter marking.

[0061] In an implementable manner, after the above-mentioned feature parameter marking, the feature parameter deviation independent display technology pre-sets feature parameter thresholds, such as the final value of the steel structure installation positioning coordinates and the stress threshold, etc., and tracks important nodes throughout the process. When there is a deviation between the feature parameter value during the installation process and the set value, different colors are used to represent the deviation level, so as to more intuitively display the real-time installation status.

[0062] In an implementable manner, the feature parameter feedback technology is based on the above-mentioned related important node tracking and other technologies. When the feature parameter value exceeds the threshold, a warning is issued, and measure optimization information is output to guide the installation process.

[0063] As an optimization, the characteristic parameter thresholds include coordinate thresholds, force thresholds, etc. A certain safety margin is reserved for the force threshold, that is, the threshold is less than the actual limit value to ensure the structural safety; a certain precision range is reserved for the coordinate threshold, that is, the threshold is greater than the actual limit value to ensure the installation and positioning accuracy of the steel structure.

[0064] As an optimization, digital identifiers are added to each component in the REVIT steel structure model, including the component model, serial number, specifications, etc.

[0065] As an optimization, for the high-position large-span cantilever inclined steel structure based on BIM, through multi-information integrated interaction, including component information, simulation collision information, installation process information, etc., it realizes collaboration and decision support among project participants from the early decision-making to the later installation. It can greatly improve the installation quality and construction efficiency of high-position large-span cantilever inclined steel structure components, and reduce construction risks and costs. However, technologies such as REVIT and LoRa are required in model construction and decision analysis, which have relatively high requirements for software operators. The accuracy of BIM model construction and data consistency should be ensured to provide early technical support for component installation.

[0066] In an implementable manner, the 3M2I model includes a Model Building module, a Mounting Collision module, a Real-time Information Monitoring module, an Interactive Information Integration module, an Installation Feedback module, etc.

[0067] In a specific embodiment of the present invention, the BIM technology solves the problems of difficult positioning and low safety in the installation process of traditional inclined steel structures. It can not only realize multi-party collaboration of installers, improve construction efficiency, but also manage and schedule the resources required during the installation process, and improve the utilization rate of resources. At the same time, the installation method of the high-position large-span cantilever inclined steel structure based on BIM technology greatly improves the success rate of installation positioning. By importing actual parameters into the model, a 3M2I installation model consistent with the actual installation environment is constructed to capture problems that may occur during the actual installation process in advance, reducing unnecessary costs (including time costs, etc.) during the actual installation process and improving the first-pass rate of the installation method.

[0068] In an implementable manner, the specific implementation steps of this installation method are as follows:

[0069] Step 1: BIM model construction; in the early planning stage, count the resources required for the installation process, including component models, component weights, installation time and costs, etc.; at the same time, analyze feasible installation plans and build a BIM model, assign various resources to the model, and build a second model that combines virtual and actual.

[0070] Step 2: Model installation deduction: Select a feasible (theoretical) installation plan, and obtain at least three installation methods for high-position large-scale cantilevered inclined steel structures through relevant data search and related technical deduction.

[0071] Step 3: Installation model "collision"; through the several installation methods selected above, the BIM full model is constructed, including the settings of load, installation form, installation path, installation environment, etc. After the settings are completed, simulate and calculate the "collision" one by one, and analyze whether the installation requirements are met through the simulation results. If the actual installation requirements on site are not met due to some reasons, corrective measures such as adjusting parameters are taken, and repeated optimization is performed to finally obtain the installation model. Each scheme is modeled "collided" one by one in the above manner to obtain a preliminary optimized installation model. If the installation model does not meet the requirements and is too far away from the original scheme target, it will be discarded.

[0072] Step 4: Installation model optimization; after obtaining the installation plan after the preliminary "collision", conduct another "collision" and compare the various plans again. The comparison and analysis scope includes the practicality of on-site implementation, installation method, measure cost, time factor and other aspects. Perform analysis and comparison of various influencing factors and finally obtain an optimal plan with strong practicality, low measure cost and short construction period.

[0073] Step 5: Reproduce the installation model; reproduce the optimization plan through the model, prepare components, installation equipment, personnel, etc. according to the plan, and guide the on-site construction through the optimization model replication.

[0074] Step 6: Real-time interaction of the installation model: During on-site construction, monitoring information points are set up and connected with the BIM platform with the help of relevant monitoring equipment. Monitoring information such as structural force, coordinate points, environmental parameters, etc. can be displayed in real time in the BIM installation model, making the installation process status clear at a glance and the installation construction status real-time.

[0075] Step 7: Interactive model feedback: According to the monitoring information points set above, the information of each monitoring point is obtained. The monitoring information provides the installer with a comprehensive understanding of the installation status, but it is impossible to immediately perceive whether the installation is carried out according to the predetermined installation target. Therefore, early warning threshold measures are taken to address this problem, so that the interactive model can quickly provide feedback and reflect the installation progress information, installation deviation information, installation adjustment information, etc. in a timely manner.

[0076] Step 8: Real-time dynamic adjustment; through the feedback information of the aforementioned interaction model, risk identification is carried out through color scale display or early warning information output, the on-site installation status is dynamically adjusted in a timely manner, and key items are continuously monitored. Continuously carry out real-time dynamic adjustment according to the feedback information of the interaction model until the installation is completed.

[0077] In an implementable manner, the BIM model assigns as many types of information to the model as possible, and better resource management is carried out in the way of resource integration. Through the model, various resources (such as material parameters, component dimensions, progress, etc.) are integrated, which helps to improve the efficiency and quality of the entire construction process.

[0078] In an implementable manner, "collision" includes "external collision" and "internal collision" of the plan. The "collision" plan requires different core installation methods. If the core installation methods are the same, they should not be selected as the installation collision plan, and only one item can be retained. After "collision", first screen through the success or failure of installation implementation, then screen through the difficulty of on-site installation implementation, and finally screen through cost control factors. The installation method of the high-position large cantilever inclined steel structure is obtained through comprehensive evaluation.

[0079] In an implementable manner, in the step of reproducing the installation model, components and tools are prepared according to the resources integrated by the system to avoid affecting the installation progress.

[0080] In an implementable manner, the installation real-time interaction model ensures the real-time nature of interaction information and reduces delay errors.

[0081] In an implementable manner, the feedback form of the interaction model can be output in different forms, such as displaying a color scale, early warning information, and even sending an early warning in the form of a text message through the Internet of Things.

[0082] As an optimization, both the feedback information and the adjustment information are recorded in the system, which is convenient for subsequent cause analysis and experience summary, and provides experience reference for similar installation projects.

[0083] As an optimization, the 3M2I model can be continuously adjusted and optimized. Through model collision - on-site installation, continuous iteration is carried out, so as to better serve the on-site steel structure installation project and continuously improve the installation positioning efficiency and quality of the high-position large cantilever inclined steel structure.

[0084] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not restrictive. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
