Description

Technical Field

[0001] This application relates to the technical field of building construction, and in particular, to a bolt construction control method and system in a building construction scenario. Background Art

[0002] During the building construction process, bolts need to be installed to connect and fix building structures. The traditional bolt installation method generally involves manual measurement and lofting to determine the bolt installation position and installation method (embedded depth, elevation, exposed length). This operation is easily interfered by the construction site environment or human factors, resulting in a disconnection or position deviation between the actual bolt installation position and the position on the pre-designed installation drawing, thereby affecting the installation effect. That is, the traditional bolt construction method implemented manually has problems such as large installation errors and poor installation quality, so it needs to be improved. Summary of the Invention

[0003] In order to reduce bolt installation errors and optimize the bolt installation effect during building construction, this application provides a bolt construction control method and system in a building construction scenario.

[0004] In a first aspect, this application provides a bolt construction control method in a building construction scenario, including: Receiving a construction guidance instruction, obtaining and analyzing the construction scenario corresponding to the construction guidance instruction, and constructing a corresponding BIM model; Based on the construction scenario, calling a preset decision tree to match a bolt installation plan for the BIM model; wherein, the bolt installation plan at least includes bolt attributes and installation parameters; Simulating the corresponding bolt installation plan in the BIM model to generate an installation effect; merging the installation effect with the bolt installation plan and outputting it for construction personnel to know the bolt installation plan.

[0005] By adopting the above technical solution, replacing manual experience with a decision tree rule base ensures a strict and high degree of matching between bolt attributes and the construction scenario. By means of simulation and rehearsal operations, potential conflicts and performance defects are exposed in advance. By integrating the whole cycle data of design, construction, and operation and maintenance through the BIM model, the intelligence and high precision of the bolt construction process are improved, and the construction and installation quality of bolts is optimized.

[0006] Optionally, the construction scenario corresponds to scenario parameters and installation effect indicators; The method further includes: Whenever a bolt installation plan is generated, storing the corresponding relationship between the bolt installation plan, the construction scenario, and the BIM model; Regularly perform multi-dimensional effect analysis on the bolt properties in the bolt installation plans stored in the historical period, wherein the multi-dimensional effect analysis includes at least the installation effect analysis of a single bolt and the installation effect analysis of any combination of bolts among the bolts matched by the bolt installation plan; According to the results of the multi-dimensional effect analysis, a reusable bolt combination is mined, and the reusable bolt combination includes combination characteristics and installation effect indicators. The preset decision tree is updated using the reusable bolt combination obtained by mining; wherein, the combination characteristics include at least bolt attributes, installation parameters, and scenario parameters.

[0007] By adopting the above technical solution, reusable bolt combinations are extracted from historical data so that they can be migrated to subsequent new scenarios for reuse, thereby reusing their installation effects and giving full play to the synergistic effect of the bolt group. In addition, this application uses intelligent analysis instead of manual experience summary to derive reusable bolt combinations, to ensure that the reusable bolt combinations are supported by data.

[0008] Optionally, the periodic multi-dimensional effect analysis of the bolt properties in the bolt installation schemes stored in the historical period further includes: Based on the bolt installation schemes stored in historical periods and their corresponding construction scenarios, virtual bolt addition and deletion adjustment operations are performed in the corresponding construction scenarios. The installation effects after the adjustment operations are simulated and evaluated, and beneficial combinations are discovered as reusable bolt combinations.

[0009] By adopting the above technical solution, considering that the reusable bolt combinations excavated from historical periods are limited and difficult to cover complex new scenarios, this solution further proposes to realize the virtual reconstruction of historical construction scenes from the existing layout through virtual addition and deletion, and simulate the installation effect, so as to actively expand the reusable bolt combinations and improve the combination diversity. The newly expanded samples are used to realize the iterative optimization of the preset decision tree, thereby improving the coverage of the preset decision tree and the matching accuracy of the matched bolts.

[0010] Optionally, the method further includes: Whenever a reusable bolt assembly is generated, predicting the overall life of the reusable bolt assembly; Based on the reusable bolt combination, the installation effect of the corresponding reusable bolt combination is simulated when each bolt in the reusable bolt combination fails individually; the degree of influence of each bolt in the reusable bolt combination on the installation effect of the reusable bolt combination to which it belongs is determined according to the installation effect obtained by the simulation, and the degree of influence is added to the installation effect of the corresponding reusable bolt combination; the degree of influence at least includes the degree of attenuation of the overall life of the bolt.

[0011] By adopting the above technical solution, the chain effect of a single bolt failure in the reusable bolt combination on the overall installation effect can be predicted, and based on this effect, the influence degree can be quantitatively generated. Thus, when outputting the bolt installation plan with the reusable bolt combination after successful subsequent matching, the construction personnel can be informed of the overall life of the reusable bolt combination and the attenuation degree of each bolt on the overall life, so that the construction personnel can make preventive response plans in advance.

[0012] Optionally, the method further includes: For the target bolt in the reusable bolt combination with an attenuation degree higher than the preset degree threshold, analyze the failure cause and the corresponding failure scenario of the target bolt, and establish the conflict relationship between the target bolt and the corresponding failure scenario; where it is satisfied that the target bolt will fail in the corresponding failure scenario; Update the preset decision tree according to the conflict relationship, so that when the construction scenario includes the scenario parameters corresponding to the failure scenario, the bolts matched by the prediction decision tree do not include the target bolt.

[0013] By adopting the above technical solution, in order to avoid only considering the physical scenario and ignoring the functional requirements (such as earthquake resistance and moisture protection) when matching bolts, which may lead to the risk of hidden failure and the inability to distinguish whether the failure is due to installation error, material mismatch or unmet scenario function, analyze the failure effect of each bolt and the corresponding failure scenario, and reverse-optimize the decision tree based on this conflict relationship, such as adding a failure prediction layer to the decision tree. When the construction scenario includes the failure scenario, the matching of the target bolt is preferentially excluded.

[0014] Optionally, the installation parameter includes the installation position; After calling the preset decision tree to match the bolt installation plan for the BIM model, the following further includes: According to the installation position of each bolt obtained by matching, define a tolerance range for each bolt obtained by matching, and calculate the installation effect corresponding to the bolt installation plan when each bolt obtained by matching is at different positions within the corresponding tolerance range; Generate the mapping relationship between the installation position and the installation effect, and add the mapping relationship to the corresponding bolt installation plan.

[0015] By adopting the above technical solution, by defining the allowable range of the installation position (tolerance range) for each bolt and calculating the change rule of the installation effect of the bolt at different positions within the tolerance range, it is convenient for the construction personnel to know and control the construction accuracy of the bolt on site.

[0016] Optionally, the method further includes: Generate candidate installation sequences for all bolts in the reusable bolt assembly, and simulate the installation process of the reusable bolt assembly in the BIM model according to each candidate installation sequence; Based on the tolerance domain of each bolt in the reusable bolt assembly, calculate the maximum offset error corresponding to each candidate installation sequence, where the maximum offset error refers to the offset amount relative to the center point coordinates of the tolerance domain; Take the candidate installation sequence with the minimum maximum offset error as the optimal installation sequence, and store the corresponding relationship between the reusable bolt assembly and the optimal installation sequence; Whenever a bolt installation plan is generated and the generated bolt installation plan includes a reusable bolt assembly, add the corresponding optimal installation sequence to the corresponding bolt installation plan.

[0017] By adopting the above technical solution, when actually installing each bolt in the bolt assembly, in order to avoid the problem that the overall position offset of the bolt assembly exceeds the limit due to the superposition of bolt deviations, the present application proposes to use the actual position of the installed bolts as the constraint condition for the subsequent bolt positioning in real time during the installation process, so as to reduce the overall position offset of the bolt assembly.

[0018] In a second aspect, the present application provides a bolt construction control system in a building construction scenario, adopting the following technical solution: A construction scenario model construction module, configured to receive a construction guidance instruction, obtain and analyze the construction scenario corresponding to the construction guidance instruction, and construct a corresponding BIM model; A bolt installation plan matching module, configured to call a preset decision tree based on the construction scenario to match a bolt installation plan for the BIM model; wherein, the bolt installation plan at least includes bolt attributes and installation parameters; An installation effect preview output module, configured to simulate the corresponding bolt installation plan in the BIM model to generate an installation effect; merge the installation effect with the bolt installation plan and output it for construction personnel to know the bolt installation plan.

[0019] In a third aspect, the present application provides a bolt construction control device in a building construction scenario, including a memory and a processor, and a computer program capable of being loaded and executed by the processor as described in any one of the methods in the first aspect is stored on the memory.

[0020] In a fourth aspect, the present application provides a computer-readable storage medium, storing a computer program capable of being loaded and executed by the processor as described in any one of the methods in the first aspect.

[0021] In summary, the present application includes at least one of the following beneficial technical effects: In this application, a decision tree rule library is used instead of manual experience to ensure that bolt properties are strictly and highly matched with the construction scenario. Simulation and rehearsal operations are used to expose potential conflicts and performance defects in advance. The BIM model integrates data from the entire design, construction, and operation and maintenance cycle to improve the intelligence and high precision of the bolt construction process and optimize the construction and installation quality of the bolts. Furthermore, reusable bolt combinations are extracted from historical data so that they can be migrated to subsequent new scenarios for reuse, thereby reusing their installation effects and giving full play to the synergistic effect of the bolt group. In addition, this application uses intelligent analysis instead of manual experience to derive reusable bolt combinations, ensuring that the reusable bolt combinations are supported by data. Furthermore, the chain reaction effect of the failure of a single bolt in the reusable bolt combination on the overall installation effect is predicted, and the degree of impact is quantified based on the impact. Therefore, when the bolt installation plan with the reusable bolt combination is output after a subsequent successful matching, the construction personnel can know the overall life of the reusable bolt combination and the degree of attenuation of the overall life of each bolt, so that the construction personnel can make targeted preventive response plans in advance.

[0026] The following is combined with Figure 1-2 This application is described in further detail.

[0027] The embodiments of this application disclose a bolt construction control method in a building construction scenario (hereinafter referred to as the construction control method), aiming to analyze the construction scenario and provide a bolt installation plan for construction workers before on-site construction for their reference. The bolt installation plan includes bolt selection, bolt installation parameters, etc., so as to replace manual experience installation, improve the intelligence and high precision of the bolt installation process, and optimize the construction and installation quality of bolts. The execution entity of the construction control method is a bolt construction control system in a building construction scenario (hereinafter referred to as the construction control system). The following will be combined with the attached Figure 1 , and specifically elaborate on the execution process of the construction control system for the construction control method.

[0028] S101, Receive a construction guidance instruction, obtain and analyze the construction scenario corresponding to the construction guidance instruction, and construct a corresponding BIM model.

[0029] In implementation, construction workers can access the construction control system in the form of a web page and enter and trigger a construction guidance instruction in the input box preset on the access interface of the construction control system. For example, enter "offshore wind turbine tower foundation", and the construction control system extracts keywords from the construction guidance instruction based on the preset knowledge graph and AI large model, and finally analyzes the construction scenario corresponding to the construction guidance instruction according to the keyword library corresponding to each preset construction scenario in the knowledge graph. For example, the keywords extracted from the above construction guidance instruction are: wind turbine tower foundation, ocean; the construction scenario corresponding to the combined matching of the foregoing keywords can be the wind turbine tower foundation scenario, and the corresponding construction scenario specifically includes a physical structure and scenario parameters. The physical structure is: wind turbine tower foundation; the scenario parameters are: marine C5 corrosion, 8-degree earthquake resistance, 50m / s wind load resistance. The construction control system is used to establish a tower foundation model (such as using Revit) according to the physical structure in the construction scenario, import ANSYS according to the scenario parameters, and add corresponding environmental loads.

[0030] S102, Based on the construction scenario, call the preset decision tree to match a bolt installation plan for the BIM model; where the bolt installation plan includes at least bolt attributes and installation parameters.

[0031] In implementation, the installation parameters include the installation location (specifically represented by the three-dimensional coordinates of the bolts on the BIM model) and the embedded depth; the construction control system first uses finite element analysis to identify the high-stress areas of the BIM model, generates the initial bolt distribution using the Voronoi algorithm, solves the optimal layout using the gradient descent algorithm, and adjusts to meet the minimum spacing constraint (in accordance with GB50017), such as the edge bolts being ≥1.5d = 54mm from the concrete edge (M36 bolts) and the center distance between bolts being ≥3d = 108mm, and outputs the total number of bolts obtained by matching and the three-dimensional coordinates of the bolts on the BIM model. Dynamically bind the concrete parameters, determine the embedded depth of the bolts through the double calculation of the concrete bond strength and the uplift force, and limit the installation torque tolerance of the bolts in the high-stress area (such as ±3%) to be stricter than that in the non-high-stress ordinary area (such as ±5%).

[0032] Next, based on a preset decision tree, determine the bolt attributes for each of the above-determined bolts in combination with the corresponding installation location and the physical structure and scenario parameters of the construction scenario. Correspondingly, the decision tree contains decision nodes for determining the physical structure and scenario parameters, and the finally output bolt attributes can include the material (such as stainless steel), the bolt surface treatment process (such as an anti-rust coating), the type (such as a hydraulic nut), and finally complete the matching.

[0033] S103, simulate the corresponding bolt installation plan in the BIM model to generate the installation effect; merge the installation effect with the bolt installation plan and output it for the construction personnel to know the bolt installation plan.

[0034] In implementation, mark the corresponding positions in the BIM model according to the distribution positions of the bolts obtained by matching, and add the bolt attributes of the corresponding bolts at the marked positions. The installation effect is specifically manifested as the tightening effect after the bolts are installed. Correspondingly, the construction control system obtains the stress data of the previously marked BIM model through finite element analysis, calls the Miner linear cumulative damage theory to calculate and estimate the service life, and can further display the stress conditions of all positions of the BIM model in the form of a stress nephogram, describe the stress magnitude in the form of a color scale, and correspondingly, can also use a life distribution nephogram with a color scale to visually describe the service life of all positions of the BIM model; thus finally taking the stress data and the estimated service life as the installation effect indicators to represent the installation effect. Finally, output the bolt installation plan with the installation effect for the construction personnel to use as a reference for bolt installation.

[0035] Optionally, the construction control method further includes the following steps: Whenever a bolt installation plan is generated, store the corresponding relationship between the bolt installation plan, the construction scenario, and the BIM model; Regularly conduct multi-dimensional effect analysis on the bolt attributes in the bolt installation plans stored within a historical period. The multi-dimensional effect analysis shall at least include the installation effect analysis of a single bolt, and the installation effect analysis of any combination of bolts among the bolts matched by the bolt installation plan. Based on the results of the multi-dimensional effect analysis, reusable bolt combinations are mined. The reusable bolt combinations include combination features and installation effect indicators, and the preset decision tree is updated using the mined reusable bolt combinations. Among them, the combination features shall at least include bolt attributes, installation parameters, and scenario parameters. Based on the bolt installation plans stored within a historical period and their corresponding construction scenarios, adjustment operations of virtual addition and deletion of bolts are performed in the corresponding construction scenarios, and the installation effects after the adjustment operations are simulated and evaluated to mine beneficial combinations as reusable bolt combinations.

[0036] In implementation, after the construction personnel complete the installation of bolts, they can regularly inspect the usage of bolts and upload the usage to the construction control system. Correspondingly, the construction control system can regularly conduct multi-dimensional effect analysis on the bolts that have been installed, combined with the corresponding construction scenarios and BIM models. The specific analysis includes the installation effect analysis of a single bolt and the installation effect analysis of the corresponding bolt combination when any combination of bolts is formed.

[0037] Exemplarily, the installation effect analysis of a single bolt can specifically be: measuring the pre-tightening force of a single bolt using a wireless force sensor (such as a piezoelectric film), and calculating the pre-tightening force decay rate. The construction control system is used to identify the loosening characteristic frequency through vibration spectrum analysis (such as a sudden increase in energy in the 5-15 Hz frequency band).

[0038] The installation effect analysis of a bolt combination can be: monitoring the stress transfer path between the bolts in the bolt combination through a strain gauge array (such as the edge bolts bearing 60% of the load), and detecting the vibration synchronism of all bolts in the bolt combination through a phase analyzer (such as setting an ideal state phase difference ≤ 10°).

[0039] Based on the above analysis results, bolt combinations whose installation effects meet the preset conditions (the preset conditions can be defined artificially in advance) are mined as reusable bolt combinations. For example, using the DBSCAN algorithm to cluster high-performance combinations (such as "stainless steel M20 + carbon steel M16, spacing 200 mm" with a 40% increase in lifespan in a corrosion scenario); discovering frequent combination rules through the Apriori algorithm (such as the probability of "shear-resistant bolts + seismic washers" appearing in roof beams is 85%); establishing an association relationship between the bolt attributes, installation parameters of each bolt in the reusable bolt combination, and the corresponding installation effects.

[0040] In addition, the construction control system is also used to load the BIM model of the historical period and import data such as the corresponding bolt distribution and bolt properties. High-stress areas (such as stress ≥ 80% of the yield strength) and low-efficiency areas (such as stress ≤ 20% of the yield strength) are identified through finite element simulation. Then, a virtual addition and deletion strategy is executed. The virtual addition and deletion strategy specifically includes: adding bolts with different properties in high-stress areas (such as replacing M16 with M20 or adding diagonal strengthening bolts), and removing redundant bolts in low-efficiency areas (such as expanding the spacing from 150 mm to 200 mm). After the construction control system executes the virtual addition and deletion strategy, it calculates the adjusted installation effect indicators, and then screens out the bolt combinations (i.e., beneficial combinations) whose installation effect indicators meet the preset conditions as reusable bolt combinations. Finally, the new reusable bolt combinations are injected into the decision tree rule library to optimize the decision tree.

[0041] Optionally, the construction control method further includes the following steps: Whenever a reusable bolt combination is generated, predict the overall life of the reusable bolt combination; Based on the reusable bolt combination, simulate the installation effect of the reusable bolt combination when each bolt in the reusable bolt combination fails individually; determine the influence degree of each bolt in the reusable bolt combination on the installation effect of the reusable bolt combination to which it belongs according to the simulated installation effect, and add the influence degree to the installation effect of the corresponding reusable bolt combination; the influence degree at least includes the attenuation degree of the overall life by the bolt to which it belongs.

[0042] For the target bolts in the reusable bolt combination whose attenuation degree is higher than the preset degree threshold, analyze the failure reasons and corresponding failure scenarios of the target bolts, and establish a conflict relationship between the target bolts and the corresponding failure scenarios; where, it is satisfied that the target bolts will fail in the corresponding failure scenarios. Update the preset decision tree according to the conflict relationship so that when the construction scenario includes scenario parameters corresponding to the failure scenarios, the bolts matched by the predicted decision tree do not include the target bolts.

[0043] In implementation, combining the above technical content, it can be known that when analyzing the installation effect, installation effect indicators with predicted service lives will be obtained, and the overall life here can be considered as the predicted service life obtained above.

[0044] Bolt failure refers to problems such as bolt fracture, loosening or corrosion. Correspondingly, the construction control system is used to remove bolts in the BIM model to simulate bolt fracture, and then analyze the stress redistribution of the remaining bolts in the reusable bolt combination. The construction control system is also used to simulate bolt loosening by reducing the bolt stiffness (such as zeroing the pre-tightening force), and then calculate the change in vibration transmission of all bolts in the reusable bolt combination. The construction control system is also used to gradually reduce the bolt cross-sectional area to simulate the failure phenomena of bearing capacity attenuation and bolt corrosion.

[0045] The construction control system is used to take the difference in the installation effect change before and after simulation as a specific representation of the attenuation degree, and then take the bolts with an attenuation degree higher than the preset degree threshold as target bolts. Based on the corresponding relationship between bolt type, failure cause, and the scenarios generated by the failure cause (hereinafter referred to as failure scenarios) stored in the preset bolt failure mode library, analyze and obtain the failure cause and corresponding failure scenario corresponding to the target bolt. For example, the reason for the failure of ordinary carbon steel M16 is salt spray corrosion (annual corrosion of 0.2 mm), and the corresponding failure scenario is the marine environment. That is, in the failure scenario, ordinary carbon steel M16 will fail due to salt spray corrosion; another example is the 8.8-grade large hexagon head bolt, which is prone to loosening (i.e., the failure cause) due to high-frequency vibration in the seismic scenario (i.e., the failure scenario).

[0046] The construction control system is used to establish a conflict relationship between the target bolt and the failure scenario, and inject this conflict relationship into the preset decision tree rule library as a negative rule. That is, a failure prediction layer is added to the preset decision tree, so that when traversing the preset decision tree according to the construction scenario to match bolts, bolts with attributes that conflict with the scenario parameters of the construction scenario are preferentially excluded; correspondingly, when a target bolt with an attenuation degree higher than the preset degree threshold appears in the reusable bolt combination, the scenario parameters of the reusable bolt combination are adaptively adjusted to delete the scenario parameters of the failure scenario that conflict with the target bolt from the scenario parameters. This operation is to adjust the applicable scenario of the reusable bolt combination, indicating that the reusable bolt combination is not applicable to the failure scenario.

[0047] Optionally, after "calling the preset decision tree to match the bolt installation plan" in S102, the following steps are further included: According to the installation position of each bolt obtained by matching, define a tolerance range for each bolt obtained by matching, and calculate the installation effect corresponding to the bolt installation plan when each bolt obtained by matching is at different positions within the corresponding tolerance range; Generate the mapping relationship between the installation position and the installation effect, and add the mapping relationship to the corresponding bolt installation plan.

[0048] The construction control method further includes: Generate the candidate installation sequences for all bolts in the reusable bolt combination, and simulate the installation process of the reusable bolt combination in the BIM model according to each candidate installation sequence; Based on the tolerance range of each bolt in the reusable bolt combination, calculate the maximum offset error corresponding to each candidate installation sequence, where the maximum offset error refers to the offset amount relative to the central point coordinates of the tolerance range; Take the candidate installation sequence with the minimum maximum offset error as the optimal installation sequence, and store the corresponding relationship between the reusable bolt combination and the optimal installation sequence; Whenever a bolt installation plan is generated and the generated bolt installation plan contains a reusable bolt combination, add the corresponding optimal installation sequence to the corresponding bolt installation plan.

[0049] In practice, the construction control system will, based on the three-dimensional coordinates of the installation position of each bolt (hereinafter referred to as the initial coordinate points), determine a three-dimensional space domain in the form of an interval (i.e., the tolerance range) for each bolt based on a preset tolerance value, and the tolerance range contains the initial coordinate points.

[0050] Next, the construction control system discretely samples within the tolerance range of each bolt to form a coordinate set composed of actual installation coordinate points. For example, if the actual coordinate point is x and x ∈ [x_min, x_max], then [x_min, x_max] is the corresponding coordinate set.

[0051] Then, taking each actual installation coordinate point as the bolt installation position respectively, analyze the installation effect using the above analysis scheme, so as to finally obtain the installation effects when the bolts are at different positions within the tolerance range (i.e., when the values of different actual installation coordinate points are different). That is, when representing the matching bolt installation positions in the form of an interval, adaptively output all possible installation effects; establish the mapping relationship between the installation effect and the actual installation coordinate point, and add this mapping relationship to the bolt installation plan and output it together with the bolt installation plan for the construction personnel to know.

[0052] In addition, the construction control system is also used to generate all possible installation sequences (i.e., candidate installation sequences, used to describe the installation order of bolts during actual installation) for all bolts in the reusable bolt combination based on the number of bolts included in the reusable bolt combination. For example, if the reusable bolt combination includes A, B, and C, the corresponding candidate installation sequences include: A, B, C; A, C, B; B, A, C; B, C, A; C, A, B; C, B, A.

[0053] Next, for each candidate installation sequence, process it according to the following steps: Traverse each bolt in the candidate installation order. If it is the first bolt, determine the actual installation coordinate point of the first bolt as the edge coordinate in its coordinate set (such as the maximum coordinate point or the minimum coordinate point). Next, for the other bolts except the first bolt, find a position point within its own tolerance domain that satisfies the following conditions as the actual installation coordinate point: For the i-th bolt, select the actual installation coordinate point i from its corresponding tolerance domain, so that the distance between the actual installation coordinate point i and each of the previous i - 1 bolts is greater than the preset distance value u, and under the condition of satisfying the foregoing conditions, the coordinate point closest to the edge coordinate of the corresponding tolerance domain.

[0054] After determining the actual coordinate points of all bolts in the reusable bolt combination, add up the distance values of each bolt's actual coordinate point from the center of the corresponding tolerance domain as the maximum offset error of the corresponding candidate installation order.

[0055] Obtain the maximum offset errors corresponding to all candidate installation orders of the same reusable bolt combination in the above manner, select the candidate installation order corresponding to the minimum value from all the maximum offset errors as the optimal installation order of the corresponding reusable bolt combination, and store the corresponding relationship between the reusable bolt combination and the corresponding optimal installation order, so as to output the optimal installation order correspondingly when calling the reusable bolt combination to generate a bolt installation plan in the subsequent process.
