Description

[0002] A construction section refers to a segment in a workflow where the work is divided into several parts with equal or similar workloads. In construction engineering, organizing workflows requires estimating the workload of each construction section to obtain a rough budget for each stage. Based on the above analysis, how to accurately determine the structural components at the edges of construction sections, thereby precisely calculating the workload of each section and ultimately helping budgeters make accurate estimates, has become a pressing technical problem.

[0003] Currently, most civil engineering quantity calculations rely on manual calculations by budgeters based on blueprints. This requires a high level of expertise from the budgeters and is inefficient with significant accuracy deviations. Calculating quantities for specific construction sections further reduces accuracy. With the development of information technology, computer-aided quantity calculation has gradually emerged. Budgeters can use computer-aided design to construct 3D models of the building structure based on blueprints and automatically calculate quantities from these models. However, for continuous construction operations, calculating quantities for each section is crucial. Precisely dividing the building structure at the edges of construction sections is a current deficiency in quantity calculation software.

It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without inventive effort are within the scope of protection of this invention.

[0027] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0028] Example 1

[0029] This embodiment provides a quantity calculation method based on construction section operations. Figure 1 A flowchart of the quantity calculation method based on construction section operations is shown, as follows: Figure 1 As shown, the quantity calculation method based on construction section operations may include steps S101 to S105, wherein:

[0030] Step S101: Obtain the three-dimensional building model and the construction section plan, wherein the construction section plan is used to divide the construction work of the three-dimensional building model;

[0031] Three-dimensional building models can be obtained by using computer-aided design software in conjunction with construction drawings. The computer-aided design software can be BIM, CAD, or SolidWorks, or conventional drawing software; no restrictions are placed here.

[0032] The construction section plan can be based on the projection plane of the constructed 3D building model. The projection plane is divided into multiple construction sections according to actual construction needs. Each construction section is represented by a plane, i.e., the construction section plan. These multiple construction sections should cover as much of the building structure as possible to ensure no unclassified work is included. Specifically, the construction sections can be divided into regular or irregular shapes; there are no restrictions here.

[0033] Step S102: Obtain the quantity calculation expression of the three-dimensional building model, wherein the three-dimensional building model includes multiple building bodies, and each building body corresponds uniquely to a quantity calculation expression.

[0034] In actual construction projects, different 3D building models are not independent but coupled together. Therefore, when calculating the quantity of work for a building, it is necessary to deduct the common parts of the building with other buildings to obtain the actual quantity of work for the building in each construction section.

[0035] In this embodiment, the calculation expressions of each building body in the 3D building model are pre-stored in the database. Since the building bodies play different roles in the actual building model, the coupling relationship between each building body and other building bodies is also different. There is a unique correspondence between the building body and the calculation expression.

[0036] Figure 2 This diagram illustrates an alternative structural layout for the building's coupling structure. Figure 2 Taking wall #1 as an example, it can be seen from the figure that wall #2, column #3 and beam #4 are all coupled with wall #1. The partial quantity calculation expression for wall #1 is: Volume = Original volume - Deducted wall volume - Deducted column volume - Deducted beam volume, and formwork area = Original formwork area - Deducted wall formwork area - Deducted column formwork area - Deducted beam formwork area. In the above quantity calculation expressions, the original volume and the original formwork volume are the original drawing specifications of wall #1, and the deducted wall, deducted column and deducted beam respectively represent the intersection of wall #1 with the building body with the coupled relationship.

[0037] Step S103: Determine the target building and associated building through the quantity calculation expression, and create the quantity calculation geometry of the target building based on the target building, associated building and construction section plan;

[0038] The target building is determined based on the current quantity calculation requirements. Then, all quantity calculation expressions stored in the database are traversed according to the target building's number. The target building's number is matched with the left-hand parameter identifier of the quantity calculation expression to determine the quantity calculation expression of the target building. The associated building is determined according to the right-hand parameter of the quantity calculation expression. The associated building can be a building that has a coupling relationship with the target building.

[0039] The quantity calculation geometry can be the geometry corresponding to the relevant parameters in the quantity calculation expression. After obtaining the target building and related building, the quantity calculation geometry of the target building is created by further analyzing the target building, related building, and construction section plan.

[0040] Preferably, step S103 may include steps S1031 to S1033, wherein:

[0041] Step S1031: Create subtractive geometry based on the target building and associated buildings;

[0042] Step S1032: Create segmented cutting bodies based on the target building and the construction section plan;

[0043] Step S1033: Perform volume intersection operations between the segmented cut body and the target building body and the subtracted geometry respectively to generate the quantity geometry of the target building body.

[0044] The subtracted geometry can be the intersecting structure of the target building and related buildings, while the segmented cut geometry can be the local structure of the target building in different construction sections.

[0045] After obtaining the segmented cut body, the segmented cut body is used to perform volume intersection operations with the original modeling body and the constructed deduction body respectively. The new geometry generated after the intersection operation is completed is the original segmented body and the deduction segmented body, which are the final computational geometry bodies participating in the calculation.

[0046] Optionally, step S1031 may include steps A1 to A3, wherein:

[0047] Step A1: Obtain the bounding box of each building in the 3D building model, where the bounding box is a closed geometry that contains the building.

[0048] Step A2: Determine the relative positional relationship between the bounding box of the target building and the bounding boxes of other buildings, and determine the associated buildings based on the relative positional relationship;

[0049] Step A3: Perform volume intersection operation on the bounding box of the target building and the bounding boxes of related buildings to generate subtracted geometry.

[0050] When creating the subtractive geometry, the bounding box of the target model is first obtained. Then, the spatial relationship between the bounding boxes of other building models and the bounding box of the target model is determined. If the two bounding boxes intersect or are tangent, they are associated, meaning that other building models that intersect or are tangent to the target building are associated building models.

[0051] Perform a volume intersection operation on the target model body and the associated building structure model body. The new geometry generated after the intersection is completed is the subtraction body.

[0052] Enclosing the building elements of a 3D architectural model within a simple bounding box, and using the shape of the bounding box to approximate the shape of the building elements, can improve the efficiency of geometric calculations. At the same time, using bounding boxes makes it easier to check for overlaps between building elements, thus improving the accuracy of quantity calculations for 3D architectural models.

[0053] Preferably, step S1032 may include steps B1 to B3, wherein:

[0054] Step B1: Obtain the projection surface of the target building;

[0055] The projection plane can be a projected view of the three-dimensional target building on a horizontal plane. The shape of the projection plane is determined by the actual outline and structure of the target building and is not restricted here.

[0056] Step B2: Determine the relative positional relationship between the projection plane of the target building and the plane of each construction segment, and determine the construction segments associated with the target building based on the relative positional relationship;

[0057] Relative positional relationships can include intersecting, tangent, and disjoint positional relationships.

[0058] Step B3: Determine the structural features of the target building and create segmented cut bodies corresponding to the construction sections associated with the target building based on the structural features.

[0059] When creating a segmented body, the projection plane of the target building is first obtained, and then all the divided construction segment planes in the 3D building model are obtained. Next, each construction segment plane is traversed in turn to determine the relative positional relationship between the projection plane of the target building and the construction segment plane, so as to determine the construction segment associated with the target building, thereby improving the accuracy of the engineering quantity calculation of the associated construction segment of the target building.

[0060] Different strategies are used to create segmented cut bodies for target building structures with different structures. Therefore, it is necessary to judge the structural characteristics of the target building and create segmented cut bodies corresponding to the construction segments associated with the target building based on the structural characteristics.

[0061] Preferably, step B2 may include steps B21 to B24, wherein:

[0062] Step B21: Extract key features of the projection surface of the target building through its structural features;

[0063] Structural features can be point structures (columns, piles, etc.), linear structures (walls, beams, etc.), and surface structures (slabs, raft slabs, etc.). Key features of the projection surface include its complete shape and centerline. When the target building's structural features are point or surface-based, the projection surface is extracted; when the target building's structural features are linear, the centerline of the projection surface is extracted.

[0064] Step B22: Determine whether the key features intersect with the plane of the construction section;

[0065] Step B23: If yes, then determine that one or more construction section planes of the intersecting area belong to the target building.

[0066] Step B24: If not, then determine that there is no construction segment associated with the target building in the construction segment plane.

[0067] For a point-structured target building, if the current construction segment's plane intersects with the target building's projection plane, then the current construction segment is one of the construction segments associated with the target building. Due to the special nature of point structures, they are generally not divided into segments during actual construction, so they should only be associated with a single construction segment. Therefore, after determining all associated construction segments of the target building, these segments need to be sorted, and the construction segment with the highest priority is assigned to the current point structure. The priority can be determined by combining the construction sequence and the drawing order of the construction segments, selecting the earliest construction segment plane in both the construction sequence and the drawing order of the construction segments.

[0068] For a target building with a linear structure, the first step is to determine the centerline of the current linear structure. Next, the relative positional relationship between the current construction section plane and the centerline is determined. If the construction section plane intersects with or completely contains the centerline, then the current construction section belongs to the linear structure.

[0069] For a target building with a surface structure, the positional relationship between the projected plane of the target building and the plane of each construction segment is directly determined. If the two intersect, the current construction segment belongs to the surface structure.

[0070] Preferably, step B3 may include steps B31 to B33, wherein:

[0071] Step B31: If the structural feature is a point structure, then the projection surface of the target building is stretched longitudinally to generate a segmented cut body of the target building.

[0072] For point-type structures, since they belong to only one construction segment, the segmented cut body can be constructed by directly using the projection surface of the target building as a reference and longitudinally stretching according to the height of the target building.

[0073] Step B32: If the structural feature is a linear structure, obtain the construction section plane to which the construction section associated with the target building belongs. Determine the cutting surface of the construction section associated with the target building through the center line of the projection plane of the target building and the construction section plane to which it belongs. Longitudinally stretch the cutting surface to generate the segmented cutting body of the target building.

[0074] For linear structures, obtain the plane of the construction segment to which the construction segment associated with the target building belongs. Using the center line of the target building's projection plane as a reference, and the point where the plane of the construction segment intersects the center line as a reference point, draw a perpendicular line along the radial direction of the linear structure, extending to both ends of the linear structure. The area finally enclosed is the cutting surface of the target building in the associated construction segment. Next, using this cutting surface as a reference, stretch it longitudinally according to the height of the target building to construct the segmented cutting body of the target building by stretching it upward by the height of the model body.

[0075] Figure 3 This diagram illustrates an optional structural schematic of a linear cut surface. Figure 3 It can be seen that the common area enclosed by the target building bodies of the associated construction section plan and linear structure is the cutting surface.

[0076] Step B33: If the structural feature is a surface structure, determine the intersection area between the projection plane of the target building and the plane of the associated construction segment, and stretch the intersection area longitudinally to generate the segmented cut body of the target building.

[0077] For surface structures, the plane where the projection plane of the model body intersects with the plane of the construction section is used as the cutting plane. The target building body is then longitudinally stretched according to its height to construct the segmented cut body.

[0078] Specifically, to ensure that the segmented cut body completely surrounds the original target building and the subtracted geometry during subsequent cutting, based on the intermediate geometry formed by longitudinally stretching according to the height of the target building, an additional tolerance height is applied downwards and upwards using the bottom and top heights of this intermediate geometry as a reference, forming the final segmented cut body. This tolerance height can be arbitrarily set according to design requirements and is not restricted here. This method ensures the accuracy of the quantity calculation geometry construction and avoids the omission of individual features of the building.

[0079] Step S104: Calculate the quantity of the geometric body, substitute the quantity of the geometric body into the quantity calculation expression, and generate the quantity of the target building body.

[0080] After obtaining the quantities of the geometric body, the assembly calculation is performed according to the initial quantity calculation expression to obtain the segmented quantities of the final target building in each construction section.

[0081] Preferably, step S104 may include steps S1041 to S1043, wherein:

[0082] Step S1041: Determine the attribute category of each structural data in the quantity calculation geometry;

[0083] The attribute categories of structured data can be volume, shell, area, and length.

[0084] Step S1042: Obtain a preset quantity calculator from the database, wherein the quantity calculator has a unique function identifier;

[0085] The preset quantity calculators can include volume calculator, shell calculator, area calculator, and length calculator.

[0086] Step S1043: Match the attribute category of the structural data with the function identifier of the quantity calculator, input the successfully matched structural data into the corresponding quantity calculator for calculation, and obtain the quantity of the quantity calculation geometry.

[0087] After generating the quantity calculation geometry, these geometry are fed into different types of engineering quantity calculators. The calculators then extract structural data such as volume, surface area, area, and length by parsing the attribute categories of the structural data of the geometry and perform calculations. Finally, the calculation results are assigned to the engineering quantity of the target building.

[0088] Step S105: Using the construction section plane as the statistical unit, the engineering quantities of the target building bodies located on the same construction section plane are summarized to generate the engineering quantities of each construction section.

[0089] When summarizing the quantities of a construction section, the quantities of the target buildings included in the plan of that construction section are combined and added together to obtain the final quantities of the current construction section.

[0090] Compared with the prior art, this embodiment has the following advantages:

[0091] (1) The construction section can achieve separate output;

[0092] (2) Supports quantity calculation for construction sections of multiple building structure types, including point structure, line structure, and surface structure;

[0093] (3) Supports accurate calculation of building structure based on actual deduction relationships.
