A method for estimating the amount of water-stop screws used in civil air defense walls

Abstract

This invention provides a method for estimating the amount of water-stop bolts used in civil defense walls. The method utilizes an existing BIM model of the civil defense area, processes the data, and uses an algorithm to calculate and statistically determine the amount of water-stop bolts used for each attribute category of components (shear walls, door sills, door connecting beams, and irregular door sections) in all walls within the BIM model. This makes the estimated amount of water-stop bolts closer to the actual usage on site, improving the accuracy of the estimation and reducing the number of repeated applications for water-stop bolt processing orders. Simultaneously, it greatly improves the statistical efficiency of estimating water-stop bolt usage and simplifies the workflow.

Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a method for estimating the amount of water-stop bolts used in civil defense walls. Background Technology

[0002] During the construction of civil defense wall structures, water-stop bolts need to be placed at required intervals due to water-stopping requirements. However, these water-stop bolts are prefabricated components in the factory, and there is a processing cycle. Therefore, the amount of components needed must be estimated in advance and an application for processing must be submitted to the factory before actual on-site construction.

[0003] The traditional method for estimating the amount of water-stop tie rods needed for civil defense walls involves manually calculating the length and height of walls of different thicknesses on two-dimensional drawings and then manually calculating the amount of components (i.e., water-stop tie rods) according to placement spacing rules. The amount needed for civil defense entrances is often abandoned due to the complexity of manual calculation. Therefore, the traditional method for estimating water-stop tie rod usage is limited by the limitations of manual calculation, making the component estimation process lengthy, time-consuming, and labor-intensive. Furthermore, because it ignores irregularly shaped structures such as civil defense entrances, the estimated results are often far less than the actual amount needed on site, leading to the need for multiple applications for additional components.

[0004] The existing methods for estimating the amount of water-stop bolts used in traditional civil defense walls rely on manual estimation, which results in low estimation accuracy. Those skilled in the art have been searching for solutions to this problem. Summary of the Invention

[0005] The purpose of this invention is to provide a method for estimating the amount of water-stop bolts used in civil defense walls, so as to solve the problem that the traditional method for estimating the amount of water-stop bolts used in civil defense walls relies on manual estimation and has low estimation accuracy.

[0022] When Δh1 < 0 and Δh2 = 0, the component is classified as a mouth-type connecting beam.

[0023] When Δh1×Δh2>0, the component attribute is classified as an irregular opening part; where Δh1 is the bottom offset and Δh2 is the top offset.

[0024] Optionally, in the method for estimating the amount of water-stop bolts used in the civil defense wall, in step S4, the calculation formula for the amount of water-stop bolts used for each attribute category of the component is as follows:

At the same time, it also greatly improves the statistical efficiency of estimating the amount of water-stop bolts used and simplifies the workflow. Attached Figure Description

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0049] Firstly, please refer to Figure 1 and Figure 2 The method for estimating the amount of water-stop bolts used in the civil defense wall includes the following steps:

[0050] First, execute step S1 to obtain the BIM model of the civil defense area, the initial plate edge spacing d required in the water-stop bolt arrangement scheme, and the spacing D between water-stop bolts.

[0051] Next, step S2 is executed to extract the geometric information of all walls in the BIM model;

[0052] S2 includes the following sub-steps:

[0053] S2.1: Filter out and hide exterior wall models and non-statistical floor models in the BIM model;

[0054] S2.2: Extract the geometric information of all walls in the BIM model under the current view; the geometric information includes at least: thickness b, bottom offset Δh1, top offset Δh2, unconnected height h, and length L; wherein, the bottom offset Δh1 is the offset relative to the bottom constraint; the top offset Δh2 is the offset relative to the top constraint; the bottom constraint is the current floor surface elevation, and the top constraint is the current floor top slab bottom elevation; the unconnected height h refers to the distance between the bottom constraint and the top constraint set in the wall's properties bar.

[0055] Next, step S3 is executed, and the component attributes are classified according to the geometric information of all walls extracted from the BIM model; wherein, the categories of component attribute classification include: shear wall, threshold, connecting beam, and irregular part of the opening;

[0056] S3 includes the following sub-steps:

[0057] S3.1: Compare the bottom offset Δh1 and top offset Δh2 in the geometric information with zero respectively;

[0058] S3.2: Classify the component attributes based on the comparison results. The classification process is as follows:

[0059] When Δh1=0 and Δh2=0, the component is classified as a shear wall.

[0060] When Δh1=0 and Δh2>0, the component attribute is classified as a mouth threshold.

[0061] When Δh1 < 0 and Δh2 = 0, the component is classified as a mouth-type connecting beam.

[0062] When Δh1×Δh2>0, the component attribute is classified as an irregular opening part; where Δh1 is the bottom offset and Δh2 is the top offset.

[0063] Next, step S4 is executed. Based on the initial plate edge spacing d, the spacing D between water-stop bolts, and geometric information, and based on the calculation formula for the amount of water-stop bolts corresponding to each attribute category of the component, the amounts of water-stop bolts N1, N2, N3, and N4 for each attribute category of the component are calculated. In S4, the calculation formula for the amount of water-stop bolts corresponding to each attribute category of the component is as follows:

[0064] Formula for calculating the amount N1 of water-stop tie rods used in shear wall structural members:

[0065] Formula for calculating the amount N2 of water-stop screws used in the sill plate component:

[0066] N2=0,h≤D;

[0067] Formula for calculating the amount N3 of water-stop bolts used in the connecting beam component at the mouth:

[0068] Formula for calculating the amount N4 of water-stop screws used in irregularly shaped parts at the mouth: Where N1 is; N2 is; N3 is; N4 is; h is the height without connection; L is the length; d is the initial plate edge spacing required in the water-stop screw arrangement scheme; D is the spacing between water-stop screws required in the water-stop screw arrangement scheme; [χ] is a rounding function with a value not greater than χ.

[0069] Next, step S5 is executed, which combines the different unconnected heights h or thicknesses b of the components with the calculated amounts of water-stop screws N1, N2, N3, and N4 of the components for each attribute category into multiple arrays; wherein, the first column of each array contains the different unconnected heights h or thicknesses b of the components, and the second column contains the amount of water-stop screws.

[0070] Next, step S6 is executed, which adds up all the second column data of all arrays with the same first column data in all the arrays to form multiple summary arrays; wherein, the first column data of each summary array is the same unconnected height h or thickness b (i.e., information related to the size of the water-stop screw, from which the size requirement of the water-stop screw can be known), and the second column data is the amount of water-stop screws used corresponding to the same unconnected height h or thickness b summary.

[0071] To facilitate understanding, the following example will be used for illustration: If S5 consists of multiple arrays including the following arrays:

[0072] Shear wall attribute components form an array: (b n1 ,N1)(b n2 ,N1)(b n3 ,N1), ...,(b nn ,N1);

[0073] The mouth threshold attribute components form an array: (b n1 ,N2)(b n2 ,N2)(b n3 ,N2), ...,(b nn ,N2);

[0074] The array of attribute components for the mouth-connecting beam is formed: (b n1 ,N3)(b n2 ,N3)(b n3 ,N3), ...,(b nn ,N3);

[0075] The array of attribute components for the irregular mouth part: (h n1 ,N4)(h n2 ,N4)(h n3 ,N4), ...,(b nn (N, N4); where n is an integer greater than 3. Correspondingly, the multiple summary arrays formed by executing step S6 include the following arrays:

[0076] (b n1 / h n1 ,N1+N2+N3+N4),(b n2 / h n2 (,N1+N2+N3+N4), ..., (b nn / h nn (N1+N2+N3+N4).

[0077] Next, step S7 is executed, outputting all the summarized arrays to serve as the estimated result for the amount of water-stop bolts needed for the civil defense wall. In other words, based on the summarized arrays, it can be determined which sizes of water-stop bolts are needed, and the corresponding amount of water-stop bolts for each size.

[0078] The estimation method of this invention utilizes the existing BIM (Building Information Modeling) model of civil defense areas. After data processing, the algorithm calculates and statistically determines the amount of water-stop bolts required for each attribute category of components (shear walls, door sills, door connecting beams, and irregular parts) of all walls in the BIM model. This makes the estimated amount of water-stop bolts closer to the actual usage on site, improves the accuracy of estimating the amount of water-stop bolts required for civil defense walls, and reduces the number of repeated applications for water-stop bolt processing orders. At the same time, it also greatly improves the statistical efficiency of estimating the amount of water-stop bolts required and simplifies the workflow.
