Description

Technical Field

[0001] The present invention relates to the technical field of building path planning, and particularly relates to an intelligent layout path planning method for building formwork. Background Art

[0002] The intelligent layout path planning method for building formwork refers to, in building construction, for the formwork layout operation, using path planning algorithms to automatically calculate the layout sequence and layout path of the formwork. The purpose of this method is to improve the efficiency of formwork layout operations by construction workers, reduce the ineffective moving distance, avoid path conflicts and repeated construction problems, thereby optimizing the construction process, shortening the construction period and reducing labor costs. The method usually combines construction drawing data, formwork component information and on-site space models to generate formwork layout paths that meet construction process constraints and space limitations, realizing intelligent and refined management of formwork construction.

[0003] Traditional planning methods fail to fully consider the dynamic changes and complexities in the construction environment. Especially in obstacle avoidance and path coherence, the handling is often not delicate enough. For example, when dealing with height differences and terrain complexities, traditional methods rely on empirical judgments rather than systematic data analysis, which often leads to misjudgments during construction, thus increasing construction costs and time. When traditional methods plan paths, in-depth interference analysis is not carried out, resulting in the interruption of construction paths or the need for re-planning, affecting the continuity and efficiency of construction. In terms of construction resource allocation, there is a lack of effective calculation and optimization tools, and the optimal allocation of resources cannot be achieved, resulting in resource waste and low construction efficiency, increasing project costs and causing construction delays, which affect the progress and quality of the entire project. Summary of the Invention

[0004] The purpose of the present invention is to solve the drawbacks existing in the prior art, and to propose an intelligent layout path planning method for building formwork.

[0014] S113: According to the elevation over-limit judgment result table, screen the component numbers determined to have an over-limit elevation difference, and perform a structural number mounting operation according to the preset boundary domain structure number in the construction drawing. Combine the component number and the boundary domain number to form a height difference interference record item, and establish a height difference interference component set.

[0015] The improvement of the present invention is that the acquisition steps of the structure data of the priority formwork layout partition diagram are specifically as follows:

[0021] S213: According to the grid interference density level value, re - sort the grid numbers from largest to smallest interference density level value, and sequentially assign the starting serial numbers of formwork laying priority to the grid numbers within the target sorting range. At the same time, record the corresponding relationship between the sorting value and the corresponding drawing area number, and establish the formwork laying priority partition diagram structure data.

[0022] The improvement of the present invention is that the specific steps for obtaining the node steel bar interference gradient information are as follows:

[0023] S311: Based on the formwork laying priority partition diagram structure data, obtain the coordinate positions of each node in the formwork laying path grid, and locate the plane position index of each node in the two - dimensional drawing coordinate system, construct the corresponding relationship between the node coordinates and the path grid numbers, and generate the node space coordinate index table;

[0028] S313: According to the component interference intensity coefficient table, map and bind the path node number and the level value based on the interference level number corresponding to the node, establish a two-dimensional information map of the node level distribution, form the mapping relationship between the path node coordinates and the level number, and generate the node steel bar interference gradient information.

[0029] The improvement of the present invention is that the specific steps for obtaining the passable node sequence of the formwork layout path are as follows:

[0030] S411: Call the node steel bar interference gradient information, set the interference intensity screening reference value for path passage control, detect the interference level number corresponding to each path node, compare the number value with the set interference coefficient threshold, and screen out the path nodes exceeding the threshold to generate a set of passable node numbers;

[0031] S412: According to the set of passable node numbers, extract the boundary connection relationship between nodes in the node connection structure diagram, construct a connection network composed of passable nodes, and perform connectivity detection on the path between the start point and the end point nodes, mark the node number sequence with path continuity, and generate a connected node sequence list;

[0033] The improvement of the present invention is that the method further includes:

Add longitudinal support rods to the insufficient grids to generate the longitudinal support layout grid information;

[0035] The longitudinal support layout grid information is specifically a grid support quantity distribution diagram, a longitudinal support spacing table, and a formwork load section division diagram.

[0036] The improvement of the present invention is that the obtaining steps of the longitudinal support layout grid information are specifically as follows:

[0043] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation on the present invention. In addition, in the description of the present invention, the meaning of "a plurality" is two or more, unless otherwise specifically defined.

[0053] Please refer to Figure 1 , the present invention provides a technical solution: an intelligent layout path planning method for building formwork, including the following steps:

[0054] S1: Obtain the component number and absolute elevation value of each beam component in the construction drawing of the civil air defense garage, and synchronously extract the component number and structural elevation value of the column nodes connected at both ends. According to the beam component ID and the structural boundary region number, perform positioning comparison to determine whether the corresponding elevation difference between the column nodes at both ends in the Z-axis direction exceeds the set allowable limit value of the beam end elevation difference. When it is determined that the limit is exceeded, record the component ID and mount it to the boundary region structure number table to generate a set of height difference interference components;

[0055] The absolute elevation value is the elevation reference value corresponding to the center of the component or the node in the design drawing, and the common unit is meters.

[0056] The allowable limit value of the beam end elevation difference can refer to the allowable height difference of components in the same span in the building structure load code, and the common control standard is in the range of 20mm - 50mm.

[0057] S2: According to the set of height difference interference components, retrieve the construction section number and the primitive geometric coordinate system to which each interference component belongs in the drawing, divide the drawing area according to the preset size grid, calculate the number value of interference components in each grid unit area, and match it with the grid area ratio to calculate the interference density level. Sort the grid numbers according to the interference density level, set the starting serial number of formwork layout, and generate the structural data of the priority formwork layout partition diagram;

[0058] The primitive geometric coordinate system refers to the position coordinate information of the component point set based on the CAD format drawing.

[0059] The grid is a commonly used density evaluation unit for dividing building construction drawings, which is convenient for aligning with the component modulus.

[0060] S3: Based on the data of the priority formwork layout partition diagram structure, obtain the coordinate positions of each node in the formwork layout path grid, and detect the number of intersection nodes and the angle distribution of the included angles of the steel bar components within the node range. Calculate the component density interference coefficient according to the number of intersections and the average included angle of the nodes, set the grade number according to the coefficient, establish the mapping relationship between the path node coordinates and the grade number, and generate the node steel bar interference gradient information;

[0061] The number of intersection nodes is the number of intersection points of different steel bar components within the path node range in the two-dimensional plane.

[0062] The included angle distribution can be detected according to the requirements of the steel bar layout angle. Usually, it is evaluated whether the included angle is concentrated between 30° and 150°.

[0063] S4: Call the node steel bar interference gradient information, set the interference coefficient threshold for path passage, perform threshold screening on each path node, and eliminate the over-limit nodes. Detect whether the remaining nodes meet the path connectivity, obtain the node path set that meets the connectivity and interference level conditions, and generate the passable node sequence of the formwork layout path;

[0064] The interference coefficient threshold is set according to the empirical value of the steel bar density in the building structure. The component density > 2.0 is common in high-resistance formwork layout areas such as the core area of shear walls.

[0065] S5: Based on the passable node sequence of the formwork layout path, obtain the concrete design pouring thickness value of the formwork layout area of the civil air defense garage and the corresponding formwork bottom coordinate grid, calculate the concrete load per unit area corresponding to each grid, and judge whether the number and spacing of the longitudinal support rods in the depth direction meet the minimum support layout spacing standard according to the formwork force design requirements. Add longitudinal support rods to the insufficient grids to generate the depth support layout grid information;

[0066] The pouring thickness value is the one-time pouring layer thickness of the floor slab, beam bottom or wall marked in the construction drawing;

[0067] The set of height difference interference components specifically includes the component number index table, the boundary area distribution number, and the node coordinate matrix. The data of the priority formwork layout partition diagram structure includes the grid number sequence, the interference density sorting value, and the formwork layout start serial number. The node steel bar interference gradient information specifically refers to the path node coordinate set, the interference gradient grade number, and the interference grade distribution map. The passable node sequence of the formwork layout path includes the passable node number sequence, the path connectivity chain index, and the avoidance path trajectory group. The depth support layout grid information specifically includes the grid support quantity distribution map, the longitudinal support spacing table, and the formwork load section division map.

[0068] Please refer to Figure 2 , and the specific steps for obtaining the set of height difference interference components are as follows:

[0069] S111: Obtain the component numbers and absolute elevation values of each beam component in the civil air defense garage construction drawings, and simultaneously extract the component numbers and structural elevation values of the column nodes connected at both ends. Based on the component numbers, construct a beam-column connection index table, establish the corresponding structural information between the beam component numbers and the column node numbers at both ends, and generate a beam-column elevation pairing data set.

[0070] Obtain the component numbers and absolute elevation values of all beam components in the civil air defense garage construction drawings, and simultaneously extract the component numbers and structural elevation values of the column nodes connected at both ends. Component classification and extraction need to be based on the layer information of the component graphic elements in the CAD drawings. Retrieve the component IDs using the layer where the beam components are located in the DWG format. For example, set the layer name of the beam components as "BLG_Layer". Use the node recognition rule to extract all components with a horizontal projection form and a cross-column connection relationship. Define the extracted component numbers as B001 to B080, and combine the coordinate attributes to extract the absolute elevation value of the center point. This value is usually reflected as a value above the ±0.000 reference line in the construction drawing annotation. For example, the elevation of component B015 is +2.800 m, and that of component B022 is +3.250 m. At the same time, identify the extension directions at both ends of the component, call the component IDs of the columns connected to the starting and ending points, and extract the node elevations of these column components in the corresponding layer (such as "COL_Layer"). For example, component B015 is connected to column C012 at the left end and column C016 at the right end, and the corresponding structural elevations are +2.600 m and +2.700 m respectively. Establish an index using the component numbers, combine the beam component number B015 with the column node numbers C012 and C016 in the data structure to establish a mapping relationship, and store it in the form of key-value as {"B015": ["C012", "C016"]}. Synchronously mount the corresponding absolute elevation and structural elevation combination in the data structure to form a triple, such as B015 → [+2.800, +2.600, +2.700]. In this way, complete the elevation data pairing of all beam components and column nodes, form a structural elevation information set of beam-column components, and store it indexed by component numbers for subsequent calling and comparison operations. At the same time, record each component and its corresponding information in tabular form, as shown in Table 1. Finally, generate a beam-column elevation pairing data set.

[0071] Table 1 Component Elevation Pairing Data Table

[0072] ;

[0073] As shown in Table 1, the elevation data of all components are derived from the node annotation information in the CAD drawings. The elevation unit is uniformly in the m system, and the data precision is set to 0.001 m. The elevation extraction process is based on the center point or edge annotation point of the graphic element for positioning and analysis, and the numerical values are automatically archived into the corresponding component structure fields for subsequent difference calculation and limit comparison.

[0074] S112: Call the beam-column elevation matching dataset, extract the structural elevation values corresponding to the column nodes at both ends of each beam member and the absolute elevation value of the beam member, calculate the elevation difference value in the Z-axis direction coordinate system, compare the difference with the allowable limit value of the beam end elevation difference set, determine whether it exceeds the elevation control limit, and generate an elevation overlimit judgment result table.

[0075] Call the beam-column elevation matching dataset, extract the structural elevation values corresponding to the column nodes at both ends of each beam member and the absolute elevation value of the beam member, perform an elevation difference calculation operation in the Z-axis direction coordinate system, and use the difference between the structural elevation of the left-end column node and the absolute elevation of the beam member, and the difference between the structural elevation of the right-end column node and the absolute elevation of the beam member to calculate the offset values at both ends respectively. Taking member B015 as an example, its absolute beam elevation is +2.800 m, the elevation of the left-end column C012 is +2.600 m, and the elevation of the right-end column C016 is +2.700 m. Then the left deviation is , and the right deviation is , and the judgment criterion is whether the maximum deviation at both ends exceeds the set threshold; this threshold is set according to the building construction formwork support specification. The allowable height difference at the connection between the beam and column members should be controlled within no more than 150 mm. Therefore, the allowable limit value of the beam end elevation difference is set , which is set on the premise of meeting the requirements of the stability of the connection part and the flatness of the formwork layout boundary. Usually, when the beam span is less than 6 m, the allowable height difference value is controlled more strictly, and it is recommended to control within 100 mm. In this implementation scenario, 150 mm is used as the general control value, which has no direct linkage with the member span and is only set separately for structural stability. Combining with the calculation example, we get , , so member B015 is determined as a member with an overlimit elevation difference. After all members complete the difference operation, the members that meet the conditions are screened out and their judgment results are recorded. Finally, the member ID and its deviation value are included in the overlimit record table to establish an elevation overlimit judgment result table.

[0076] S113: According to the elevation overlimit judgment result table, screen out the member numbers determined to have an overlimit elevation difference, and perform a structural number mounting operation based on the preset boundary domain structure numbers in the construction drawing. Combine the member number and the boundary domain number to form a height difference interference record item, and establish a set of height difference interference members.

[0077] According to the elevation exceedance judgment result table, the component numbers with confirmed elevation deviation exceeding the limit are screened one by one, and the boundary area numbers of their locations are located in the CAD drawings. The boundary area numbers are usually divided into structural functional zoning areas by the design unit, and the numbering format is such as "D1", "D2", etc. Each component has a logical layer label or attribute block field attached to the element in the drawing, which can read the construction functional area number information to which it belongs. For example, B015 is located in the "D2" area of the construction drawing. The additional field of the element is read to determine that its structural area number is D2. The component number and its boundary area number are combined to form a structural association identifier, which is recorded as a key-value mapping of {"B015": "D2"}. Finally, the numbers of all components with elevation difference exceeding the limit and their corresponding boundary area structure numbers are jointly stored to establish a structural intermediate result dataset for subsequent formwork priority classification and sorting, and a set of elevation difference interference components is established.

[0078] See also Figure 3 ,The steps for obtaining the structure data of the priority layout partition graph are as follows:

[0079] S211: Based on the height difference interference component set, according to the component number of each interfering beam component, extract the structural construction section number and the element geometric coordinate point set corresponding to the component number in the drawing, establish a binding index relationship between the component number and its corresponding construction section number and element geometric coordinates, and generate a component spatial positioning index set;

[0080] After obtaining the component number of each interfering beam component in the height difference interference component set, it is necessary to read the component structure partition number field included in the construction drawing metadata. This field usually exists as a block parameter in the DWG format drawing. The component structure ownership relationship can be obtained by extracting the field name of the AutoCAD data table. For example, the construction section number of component B011 is S03, and that of B012 is S04. Then, the geometric vertex coordinate set in the primitive set corresponding to components B011 and B012 is extracted and defined as a two-dimensional coordinate point set. , where the coordinates are in the form of (x, y). The extraction accuracy must reach the millimeter level and be converted to a unified engineering coordinate system. The component number, structural partition number, and element coordinate set are integrated into a triple index data set, forming a record structure of {"B011": ["S03", [(x1,y1), (x2,y2),…]]}. This is then used to construct a component spatial positioning information dataset containing multiple components. For example, component B011, whose structural partition number is S03, has component coordinates of [(1.2, 3.0), (2.0, 3.8), (2.4, 3.0)]. During the index construction process, the physical area represented by the construction section number is also recorded, such as "East Section of the Basement Level 1 Parking Area." Using the component number as the key, the structure number and coordinate set are bound to a spatial index table, ultimately obtaining the component spatial positioning index set.

[0081] S212: According to the component spatial positioning index set, call the coordinate point set of each graphic element component, divide the drawing area grid according to the target size, count the number of interfering components in each grid cell, and perform ratio matching with the grid area value. Use the formula:

[0082] ;

[0083] Obtain the grid interference density level value through calculation;

[0084] Among them, represents the interference density level value of the grid , represents the number of interfering components in the grid , represents the area normalization value of the grid , represents the th interfering component in the grid 's coordinate position, represents the coordinate value of the centroid position of the interfering components within the grid ;

[0085] This value is used to measure the distribution density and central tendency of construction interfering components in the formwork layout area, mainly reflecting the component complexity caused by the excessive height difference of beams in each grid area, and is an important decision-making index for preferentially planning the formwork layout area. The first item is the component density (quantity / area) to measure the "dense degree" of interference, the second item is the average distance of all interfering components to the centroid to measure their "central degree", and the overall product reflects the formwork layout complexity and formwork layout risk of the grid area. The larger the value, the more interfering components and the more discrete the distribution in the area, and the greater the formwork layout difficulty; it is used to guide the priority sorting and the determination of avoidance areas.

[0086] According to the component spatial positioning index set, extract the spatial position point set of the components in the coordinate system, divide the area with an equilateral grid of 2 m × 2 m according to the drawing size, and set the area numbers after division to numbers such as G01 to G10. Count the numbers of all components inside each grid cell and count the number of interfering components , and set a standard normalization value for each grid area. Subsequently, convert the component coordinate point set into the grid coordinates occupied by its corresponding grid number. Obtain the center point position of all components in each grid within the grid, and obtain the centroid coordinates of the component set in the grid by means of average calculation, the centroid position is represented by the average value of the central points of the component numbers. The sum of the absolute values of the Euclidean distances between the central points of all components and the centroid is divided by the number of components to obtain the coordinate dispersion, and finally substituted into the following formula:

[0087] ;

[0088] In the formula, represents the interference density level value of the grid . This value is used to measure the comprehensive expression of the component distribution density and the coordinate dispersion trend in this area. The larger it is, the stronger the formwork interference effect.

[0089] The descriptions of each parameter are as follows:

[0090] : By counting the number of interfering components falling into the grid number, the unit is pieces;

[0091] : Set as a fixed value , which is the normalized expression of the grid area of 2m × 2m;

[0092] : The th interfering component's two-dimensional coordinate position within the grid , the unit is m, and it comes from the central point coordinates of the construction drawing elements;

[0093] : The average value of the central point coordinates of all components in the grid , representing the component aggregation center point;

[0094] : The sum of the absolute values of the coordinate differences between all components and the centroid;

[0095] Taking G01 as an example, the number of interfering components is , the component coordinate points are [2.1, 2.4, 3.0], and the centroid position is , and the calculation process is as follows:

[0096] ;

[0097] ;

[0098] Similarly, the corresponding values are substituted into the calculations for other grids in the table, as shown in Table 2:

[0099] Table 2 Grid interference density level value calculation table

[0100] ;

[0101] The results show that when , it indicates that there is a distribution of interference components with high density and high dispersion in the grid, and actions such as reconfiguring the formwork laying path and optimizing the structure need to be considered first. The determination boundary As the interval reference value for dividing the interference intensity, this reference value is set based on the typical area where beam formwork overlaps and column intersections often appear in the construction drawings, with 2 - 4 components / grid. When the actual component density exceeds 1 component / ㎡, there are often obstacles in choosing the formwork laying path. Therefore, the critical value of interference intensity is constructed as 0.5.

[0102] S213: According to the grid interference density level value, re - sort the grid numbers from large to small according to the interference density level value, and sequentially assign the formwork laying priority start serial numbers to the grid numbers within the target sorting range. At the same time, record the corresponding relationship between the sorting value and the corresponding drawing area number, and establish the structure data of the priority formwork laying partition map.

[0103] According to the grid numbers and their corresponding interference level values recorded in the interference density sorting sequence list , arrange them in descending order according to the value size. Set the formwork laying start priority for the grid numbers in the top 10% of the sorting results. Define the formwork laying start serial number as the number index from 0 to 9, and assign values in sequence according to the sorting. Set the numbers exceeding 10% as the postponed formwork laying partition area. Record the mapping table of the new and old numbers formed by the sorted numbers and the original area numbers in the drawing. This mapping relationship uses the grid number as the key and the interference level sorting serial number as the value, and finally generates the structure data of the priority formwork laying partition map.

[0104] Please refer to Figure 4 , the steps for obtaining the interference gradient information of node steel bars are specifically as follows:

[0105] S311: Based on the structure data of the priority formwork laying partition map, obtain the coordinate positions of each node in the formwork laying path grid, and locate the plane position index of each node in the two - dimensional drawing coordinate system. Construct the corresponding relationship between the node coordinates and the path grid number, and generate the node space coordinate index table;

[0106] Based on the structure data of the priority formwork laying partition map, extract all the path node numbers in the formwork laying path. By traversing the layout elements corresponding to the path grid in the drawing, obtain the geometric center point coordinates of each node, and map this coordinate to the two - dimensional plane coordinate system, and correspondingly mark it as the plane position index , for example, the central point coordinates corresponding to node ND01 are (10.2, 5.6), and ND02 is (12.8, 5.9). The node numbers and their planar coordinates are stored in the index table as key-value pairs. At the same time, the corresponding field of the path grid number to which the node belongs is established, and a structural mapping table between the node and the grid is constructed. For the specific implementation process, two-dimensional coordinate data is used as the main key index field of the node to establish a mapping, expressed as {"ND01": [G01, (10.2, 5.6)]}. The numbers, coordinates, and the path segments to which all path nodes belong are mapped into the two-dimensional index table, and finally, the node space coordinate index table is generated.

[0107] S312: According to the node space coordinate index table, call the two-dimensional coordinate positions of each node, detect the number of intersection points and the set of intersection angles of the steel bar components within the detection range, extract the number value of the intersection points and the average value of the intersection angles, and use the formula:

[0108] ;

[0109] Calculate to obtain the interference intensity coefficient value of the node, and allocate the interference level number based on the interference intensity coefficient value, establish the corresponding relationship between the interference coefficient and the path node, generate the component interference intensity coefficient table;

[0110] Among them, represents the component interference intensity coefficient of the path node ; is the number of steel bar intersection points within the range of the path node ; is the normalized value of the area of the template plate corresponding to the path node ; is the average value of the steel bar included angles corresponding to all intersection points of the node, and

[0111] is the ideal intersection angle standard value of the steel bars specified by the design;

[0112] According to the node space coordinate index table, read the two-dimensional coordinate positions corresponding to each path node number one by one. Set a range of 0.5 m radius centered on the node as the interference detection area. Extract the end point data of the intersecting steel bar components within this area, and judge whether there are spatial intersections or coincidence points. Through the line segment intersection detection function of geometric primitives, count the number of intersection points within this range, defined as , and record the included angle between the two steel bar line segments corresponding to each intersection point. Calculate the average value of all included angle values to obtain the average included angle , and adopt the normalized value of the template node area to represent the effective layout area corresponding to the template at this node. Calculate for each node using the following formula:

[0113] ;

[0114] Among them, represents the component interference strength coefficient of the path node . This coefficient is used to comprehensively reflect the steel bar crossing density and angle deviation trend within the path node area. The higher the value, the more seriously the path layout is interfered by the steel bar structure.

[0115] The parameter meanings are explained as follows:

[0116] : The number of steel bar intersection points within the range of the path node , in units of pieces, judged by the intersection coordinates of each steel bar in the drawing;

[0117] : The normalized value of the template plate area corresponding to the path node, in units of ㎡, and the normalization standard is the single-piece design area of the template;

[0118] : The average included angle of all intersection points, in units of degrees (°);

[0119] : The ideal steel bar included angle reference value, set as . According to Article 8.2.6 of the "Code for Construction of Concrete Structures" GB 50666-2011, the steel bar included angle should preferably be arranged vertically.

[0120] Taking the path node ND01 as an example, assume the number of intersection points , the normalized value of the template area , the average included angle , the ideal included angle , substitute into the formula for the calculation process as follows:

[0121] ;

[0122] Similarly, Table 3 shows the input parameters and calculation results of multiple path nodes:

[0123] Table 3 Calculation Table of Interference Intensity Coefficient of Path Nodes

[0124] ;

[0125] This result indicates that when , the interference density of the node has reached the intervention threshold for steel bar layout, and path avoidance planning for formwork layout should be carried out. This threshold is the reference value for dividing the benchmark interference level, which is extracted from the layout interference experience of common node groups in the steel bar overlapping section in actual projects and set with reference to the lower limit of the standard steel bar spacing layout limit condition, and is set to 50 for use in node priority division processing. This value does not change with the node position, but is jointly set by the number of intersection points and the included angle deviation.

[0126] S313: According to the component interference intensity coefficient table, based on the interference level number corresponding to the node, map and bind the path node number with the level value, establish a two-dimensional information map of the node level distribution, form the mapping relationship between the path node coordinates and the level number, and generate the node steel bar interference gradient information;

[0127] According to the interference level numbers corresponding to each path node recorded in the component interference intensity coefficient table, map all path nodes into the two-dimensional drawing coordinate system one by one according to the number, and render their interference level values into the drawing path grid coordinates in the form of a heat map, construct the node layout level map in the drawing space, set the color scale interval of the level partition, and divide it into a low interference area ( ), a medium interference area ( ), and a high interference area ( ), establish a two-way index between each node coordinate point and its corresponding level number, and record the corresponding relationship of the node number, coordinate, and level number, construct a two-dimensional mapping index map for formwork layout path avoidance calculation, and finally form the node steel bar interference gradient information.

[0128] Please refer to Figure 5 , and the specific steps for obtaining the passable node sequence of the formwork layout path are as follows:

[0129] S411: Call the node steel bar interference gradient information, set the interference intensity screening reference value for path passage control, detect the interference level number corresponding to each path node, compare the number value with the set interference coefficient threshold, screen out the path nodes exceeding the threshold, and generate a set of passable node numbers;

[0130] After calling the node steel bar interference gradient information, extract the numbers and corresponding interference intensity coefficient values of all path nodes , and set a unified screening reference value As the basis for judging path passability, the threshold is set to 50. Referring to the upper limit setting of the interference control for safe passage of the operation channel in the construction safety regulations of the building template, and combining the component density of the path nodes and the allowable range of the steel bar angle deviation, the comprehensive empirical value is taken between 40 and 60, and the intermediate value of 50 is taken as the screening criterion. By judging the of each path node is less than , if it is greater, it is regarded as a blocking node with too strong interference and is excluded from participating in the subsequent path layout. During the screening process, one-to-one comparison is performed. Taking the path node ND01 as an example, its , and it is retained in the passage set; the path node ND02 is 58.5, exceeding the reference value, so it is excluded. After screening, the numbers of all path nodes that meet the condition are grouped together, and the passage path node set is recorded and formed, as shown in Table 4, and finally the passage node number set is generated.

[0131] Table 4 Path Node Passability Screening Table

[0132] ;

[0133] As shown in Table 4, only ND01 and ND03 meet the screening conditions and are included as passage path component nodes in the subsequent construction of the grid structure.

[0134] S412: According to the passage node number set, extract the boundary connection relationship between nodes in the node connection structure diagram, construct a connection network composed of passage nodes, and perform connectivity detection on the path between the starting point and the ending point nodes, mark the node number sequence with path continuity, and generate a connected node sequence list;

[0135] According to the passage node number set, call the path grid connection matrix in the node connection structure diagram, read the connection boundaries between nodes from it, and construct the edge set between passage nodes , this set represents the connection state between nodes based on the two-dimensional grid topology structure. Taking the existence of a connection edge between ND01 - ND03 as an example, it is represented as the edge {ND01, ND03}, and a graph structure is constructed , where is the passage node set, is the set of effective connection edges between nodes. Through graph traversal operations, the connectivity of the path between the starting node and the target node is detected. Taking ND01 as the starting point and ND03 as the ending point, if there is a path connecting ND01 to ND03 in this graph structure, it is recorded as the connected path sequence {ND01, ND03}. If there is no connectivity relationship, the path is broken and not included in the result. The connectivity relationship between all passage nodes is detected pairwise, and the combinations of node numbers with continuous path connections are recorded and formed into a path sequence according to the connection order, and finally a connected node sequence list is generated.

[0136] S413: Call the connected node sequence list, screen out the node group with the interference level number lower than the set threshold according to the node numbers with path connection relationship, perform continuous sorting and unique identification annotation on their path numbers, establish a complete formwork layout path number index, and generate a passable node sequence for the formwork layout path.

[0137] Call the connected node sequence list, read the node numbers involved in each path one by one, compare with the interference level number field in the node steel bar interference gradient information, screen out all nodes with the level number less than or equal to 2 as the low-interference area node group to construct available path segments, set the principle of path number continuity, that is, sequentially increase the identification in the grid row and column order from the path start point, assign a unique number to each path segment, establish a unique binding relationship between the nodes within the path segment and the path segment number, and form a path number index structure. And use the relative displacement direction between nodes as an additional field to record in the path index table, expressed as "ND01 → ND03, path number P01". After completing the construction of all connected path segments, integrate them into a path node sequence set, and finally generate a passable node sequence for the formwork layout path.

[0138] Please refer to Figure 6 , and the specific steps for obtaining the deep support layout grid information are as follows:

[0139] S511: Based on the passable node sequence of the formwork layout path, obtain the bottom coordinate index of each layout grid in the civil air defense garage formwork layout area, collect the designed concrete pouring thickness value corresponding to each grid area, construct a coordinate-thickness mapping relationship table according to the formwork layout grid number and thickness value, and generate concrete thickness grid mapping data.

[0140] Based on the passable node sequence of the formwork layout path, extract the bottom coordinates corresponding to each formwork grid, call the structural coordinate layer of the layout area in the drawing, identify the spatial position information of each grid, perform number identification on it, and represent it using the two-dimensional coordinate index rule as {G01: (x1, y1)}. Synchronously call the concrete pouring thickness annotation layer in the design structure drawing, match it according to the spatial position of the formwork grid, and extract the designed concrete thickness value corresponding to each grid. , such as the thickness at G01 is 0.25 m and G02 is 0.35 m. Corresponding the thickness value with the coordinate number one by one, construct a two-way mapping table from grid number to thickness value, expressed as {"G01": 0.25, "G02": 0.35}, summarize the combined results of the component coordinate index and thickness value in each numbered area, and finally generate concrete thickness grid mapping data.

[0141] S512: According to the concrete thickness grid mapping data, extract the thickness value and formwork bottom area data corresponding to each grid, and use the standard formwork unit bearing capacity value in the design specification to calculate the matching relationship between the unit area load value and the formwork bearing standard. Use the formula:

[0142] ;

[0143] Perform operations to obtain the compression matching ratio of each formwork layout grid, determine whether it meets the support layout spacing control criterion, obtain the layout grid numbers that require additional supports, and generate a longitudinal support additional index table;

[0144] Among them, represents the compression matching ratio of the th formwork layout grid, is the normalized value of the concrete pouring thickness corresponding to the th formwork layout grid, is the concrete density constant, is the th normalized value of the formwork bottom area in the th formwork layout grid, is the longitudinal coordinate of the th already installed support rod in the th formwork layout grid, is the average value of the longitudinal coordinates of the already installed support rods in the th formwork layout grid, is the number of already installed support rods in the

[0145] This value measures whether the formwork unit has sufficient longitudinal support capacity under a specific pouring load, and is used to evaluate whether the current support layout meets the structural safety standard. The first item is to calculate the unit area load value (i.e., the compressive strength of the formwork bottom); the second item is the "discrete offset" of the support layout distribution, that is, the longitudinal uniformity; the product of the two gives the comprehensive matching relationship between the structural force and the support layout. A too high value indicates that the unit load is too large or the support is unevenly distributed, and additional support points are required. It is used for safety checking and additional layout recommendation.

[0146] According to the concrete thickness grid mapping data, for each grid number extract the designed concrete thickness and the formwork bottom area , call the standard design density constant , and use the following formula:

[0147] ;

[0148] Calculate the compression matching ratio for each grid. Taking G01 as an example, the thickness is 0.25 m, the area is 2.0 m2, and the number of support rods , the set of longitudinal coordinates is , calculate the average ordinate , the total deviation is , substitute into the formula to get:

[0149] ;

[0150] Calculate the other grids in the same way. See Table 5 for the remaining parameters and calculation results. When , it is determined as an area with insufficient support and additional support is required. This value is the control reference value for the layout spacing of formwork supports. According to the formwork construction safety code, the ultimate load of the support should not exceed the standard bearing capacity of the formwork system, which is 3.0 kN / m2.

[0151] Table 5 Compression ratio matching calculation table for formwork layout grids

[0152] ;

[0153] As shown in Table 5, both G02 and G03 exceed the matching reference value of 3.0, and additional support is required in the corresponding areas. Finally, generate a longitudinal support additional index table.

[0154] S513: Call the longitudinal support additional index table, set the coordinates for the new longitudinal support rods in each grid area with insufficient layout, construct an index that binds the new coordinate group of the support rods to the layout area number, summarize the layout status map, establish a full map of the support layout, and generate the information of the longitudinal support layout grid.

[0155] Call the longitudinal support additional index table, read the formwork grid area information corresponding to each number, compare with the structural coordinate data of the construction drawing, calibrate the longitudinal coordinates of the new support rod points in this area, and adopt the principle of equal-distance shortening. When the original spacing is 0.6 m, the additional spacing is adjusted to 0.4 m. Set the coordinates of each new support point according to the row and column structure. For example, the original support points of G02 are at the positions of 1.0 m and 1.2 m in the depth direction, and the new support point is located at 1.1 m. Combine and record the original support points and the new coordinates to form a support group {1.0, 1.1, 1.2}, and bind the coordinate group and the area number together and store them in the layout index table. At the same time, draw the support layout plan as a record of the support layout status structure. Finally, establish a full map of the support rod layout structure and generate the information of the longitudinal support layout grid.
