Description

Technical Field

[0001] This invention relates to the field of underground earthwork construction technology, and specifically to a method for deducting and adjusting the amount of reinforcement in the bottom raft slab of a concrete wall based on BIM technology. Background Technology

[0002] Project costs (PC) refer to the estimated or actual construction expenses incurred during the construction period of a project. PC is one of the main bases for evaluating the rationality and investment efficiency of total investment and individual investments. It is essential to utilize PC data when evaluating the rationality of land prices, building and installation product and equipment prices. It can also be used to evaluate the debt repayment capacity, profitability, and macroeconomic benefits of a construction project. PC is also an important basis for evaluating the management level and operating results of construction and installation enterprises. PC has received unprecedented attention from government-invested projects, enterprise-invested projects, foreign-invested projects, privately-invested projects, and construction contractors. Currently, investment estimates, preliminary estimates, budgets, and settlements are all closely related to "work volume," and none can exist independently of "work volume." Therefore, to determine and control PC effectively, strong emphasis must be placed on the crucial basic quantity surveying work in PC cost management.

[0003] In the context of the vigorous development of BIM technology applications, the integration of traditional engineering cost estimation with BIM technology is an inevitable trend and a necessary condition for accurate quantity surveying in engineering projects. Currently, various BIM modeling and quantity surveying software programs are flourishing in the market, but they are mainly developed and optimized for building construction projects. In addition, due to software technology development issues or software engineers' lack of in-depth understanding of relevant professional engineering specifications and rules, the functional development of BIM modeling and quantity surveying software for metallurgical industrial engineering and municipal engineering is not thorough enough, failing to meet the actual usage requirements of project participants. Due to the limitations of BIM modeling and quantity surveying software in operation techniques, such as the inability to deduct or delete raft foundation reinforcement at the overlap of concrete wall components and raft foundations, the quantity of this reinforcement cannot be statistically processed in the same BIM model, requiring manual verification and reducing the efficiency of quantity verification work.

[0004] Therefore, developing a method that can statistically calculate the raft slab reinforcement at the point where the concrete wall component and the raft foundation overlap in the same model without manual calculation is of great practical significance. Summary of the Invention

[0005] Due to the aforementioned deficiencies in existing technologies, this invention provides a method that can complete the statistical calculation of raft slab reinforcement at the overlap of concrete wall components and raft foundation in the same model without manual calculation. This solves the problems of existing BIM modeling and quantity calculation software being unable to complete the engineering cost calculation of raft slab reinforcement at the overlap of concrete wall components and raft foundation, requiring manual verification, and having low work efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A method for deducting and adjusting the quantity of reinforcement at the bottom of a concrete wall raft slab based on BIM technology includes the following steps:

[0008] (1) Model the raft foundation and concrete wall components, draw the surface reinforcement within the raft foundation area and import the relevant reinforcement parameters of the concrete wall components;

[0009] (2) Draw temporary beam components in the overlapping area of ​​the raft foundation and the concrete wall foundation;

[0010] (3) Adjust the anchorage length of the raft foundation reinforcement on the inner side of the concrete wall according to the specifications and make a summary calculation to obtain the amount of raft foundation reinforcement work after deduction due to the arrangement of temporary beam components.

[0011] (4) Delete the temporary beam components and lock the inner side of the raft foundation reinforcement of the already generated concrete wall. Fix the calculation function of the reinforcement at the intersection of the concrete wall components and the raft foundation, and no longer participate in the subsequent overall model engineering quantity calculation. This prevents the layout range of the raft reinforcement after the layout is completed from changing, and prevents the secondary calculation after the temporary beam components are deleted from generating new data, generating redundant steel reinforcement engineering quantity, and interfering with the later overall engineering quantity extraction and application.

[0012] (5) Adjust the anchorage length of the raft foundation reinforcement on the outside of the concrete wall with the overhang structure, and recalculate to obtain the accurate engineering quantity of the reinforcement of the overall raft foundation.

[0013] This invention, combined with the actual conditions of the proposed project, innovates and improves the modeling method, enabling precise adjustment and arrangement of the reinforcement in the overlapping parts of the concrete wall and raft foundation components. This ensures that the drawing and calculation of the bottom reinforcement of the concrete wall in the overlapping parts meet the design specifications and drawing requirements, and that the 3D reinforcement usage in the model is consistent with the net usage on site. Relying on the BIM model, it provides accurate data support for the construction project, guiding the construction team in planning construction and the business department in cost accounting and control. The statistics of the raft foundation reinforcement at the overlapping parts of the concrete wall components and raft foundation can be completed in the same model, eliminating the need for manual calculation and greatly improving work efficiency.

[0014] This invention presents a method for deducting and adjusting the reinforcement quantity of the bottom raft slab of a concrete wall based on BIM technology. By combining professional atlases, drawing specifications, and flexible combination modeling, it achieves the goal of refined quantity calculation, meeting the needs of professional work and market use. The overall steps are simple, the data processing volume is small, and the cost is low. It makes full use of existing mature technologies, namely conventional BIM quantity calculation software. Through the reconstruction and analysis of existing BIM modeling methods, it builds a BIM technology implementation framework for refined adjustment of reinforcement at special nodes, breaking through the existing technical barriers of electronic quantity calculation and showing good application prospects.

[0018] As described above, in the method for deducting and adjusting the quantity of reinforcement at the bottom of the raft foundation of the concrete wall based on BIM technology, the height and width of the temporary beam components are matched with the raft foundation and the concrete wall foundation, respectively.

[0019] The above-described method for adjusting the quantity of concrete wall bottom raft foundation reinforcement based on BIM technology, specifically adjusting the anchorage length of the outer raft foundation reinforcement of the concrete wall with outward extensions, involves adjusting the anchorage length of the outer raft foundation reinforcement of the concrete wall with outward extensions according to the specific end structure of the raft foundation, while ensuring the quantity of reinforcement on the inner side of the concrete wall raft foundation, and ensuring that the length of a single reinforcement bar on the outer side of the concrete wall raft foundation meets the requirements of the specifications.

[0020] The above-mentioned method for deducting and adjusting the quantity of reinforcement at the bottom of the concrete wall raft slab based on BIM technology refers to the standard 16G101-3, the standard for concrete structure construction drawings.

[0026] In addition, the present invention provides a computer-readable storage medium storing computer-readable instructions, which, when executed by a processor, implement the method for deducting and adjusting the amount of concrete wall bottom raft slab reinforcement based on BIM technology as described above.

[0027] The above-mentioned method for deducting and adjusting the amount of concrete wall bottom raft slab reinforcement based on BIM technology can be compiled into a software program and installed on a computer device or computer-readable storage medium, which will facilitate the promotion and application of the above method.

[0038] The structure of the present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0039] Example 1

[0040] A method for deducting and adjusting the quantity of reinforcement at the bottom of a concrete wall raft slab based on BIM technology, comprising the following steps (step sequence as follows): Figure 1 As shown):

[0041] (1) Establish the raft foundation according to the plan layout requirements of the structural drawings and draw the reinforcement within its range. Establish concrete wall components on other floors and input their relevant reinforcement parameters.

[0042] (2) Draw temporary beam members in the overlapping area of ​​the raft foundation and the concrete wall foundation. The height and width of the temporary beam members should match those of the raft foundation and the concrete wall foundation, respectively.

[0043] (3) Based on the operations in steps (1) and (2), the anchorage length of the raft foundation reinforcement on the inner side of the concrete wall is adjusted according to the specifications of the drawing set (Concrete Structure Construction Drawing Set 16G101-3) and the calculation is summarized to obtain the raft foundation reinforcement quantity after precise deduction due to the arrangement of temporary beam components.

[0044] (4) Delete the temporary beam components in the original model step (2), and lock the inner raft foundation reinforcement of the already generated concrete wall to prevent new data from being generated in the secondary calculation after the temporary beam components are deleted.

[0045] (5) On the premise of ensuring the accuracy of the number of inner raft foundation reinforcements obtained in step (3), the anchorage length of the outer raft foundation reinforcements of the concrete wall with outward extension is adjusted according to the specific end structure of the raft foundation. This ensures that the length of a single reinforcement bar of the outer raft foundation of the concrete wall meets the requirements of the concrete structure construction drawing set 16G101-3. The calculation is then summarized again to obtain the accurate engineering quantity of the reinforcements of the overall raft foundation.

[0046] The above method has been applied; specifically, the structural drawing plan in step (1) is as follows: Figure 2 As shown, the purpose of step (1) is to lay the groundwork for the initial BIM model construction, thus paving the way for subsequent fine-tuning of the reinforcement; the cross-sectional views of the concrete wall components and raft foundation are shown below. Figure 3 As shown, step (2) is based on Figure 3The arrangement of temporary beam members is completed. The size of the temporary beam members is defined as 400*600. Step (2) creates the deduction relationship of the raft slab reinforcement at the intersection of the concrete wall members and the raft foundation. The above-mentioned raft foundation is judged to be "with an overhanging structure at the end" according to the structural form. The raft slab reinforcement in the Y direction perpendicular to the raft slab reinforcement at the intersection of the concrete wall members and the raft foundation is required to "extend to 12d inside the concrete wall support and at least to the center line of the support" according to the requirements of the concrete structure construction drawing set "16G101-3". The raft foundation is divided with the concrete wall as the dividing line, and the Y-direction raft slab reinforcement, the Y-direction reinforcement of the inner side of the concrete wall and the Y-direction reinforcement of the overhanging structure are arranged separately. In the steel reinforcement business attributes, change "steel reinforcement anchorage" to 12d and "steel reinforcement lap" to 0, summarize and calculate the steel reinforcement quantity and fix the steel reinforcement (the reason for fixing the steel reinforcement is the same as above), merge the raft foundation components, and by viewing the three-dimensional steel reinforcement and the quantity calculation formula, the calculation formula for the Y-direction reinforcement on the inner side of the concrete wall is: net length + max(12*d, 200), and the calculation formula for the Y-direction reinforcement of the extended structural part is: net length + max(12*d, 200) - bhc + 12d, which meets the requirements of the drawing set specifications. While accurately deducting the quantity of raft foundation reinforcement at the junction of the concrete wall components and the raft foundation as mentioned above, we ensure the standardized modeling of its associated steel reinforcement, thereby ensuring the reliability of the steel reinforcement quantity data source for the entire raft foundation area.

[0049] The memory stores computer-readable instructions, and when the processor executes the computer-readable instructions, it implements the method for deducting and adjusting the amount of concrete wall bottom raft slab reinforcement based on BIM technology as described in Example 1.
