[0041] This application provides a method for identifying and generating gaps in building quantity calculation. Figure 1 This is a flowchart illustrating the steps of the method for identifying and generating gaps in building quantity calculation according to an embodiment of this application, as follows: Figure 1 As shown, the method includes the following steps:

[0042] Step S102: Obtain the drawing area to be generated by gap recognition;

[0043] It should be noted that the building components in this drawing area can be extracted from existing CAD drawings or directly from the drawing area in the building quantity calculation software, such as beam components, wall components, core mold components, etc. in the following steps.

[0044] Step S104: Identify beam members and wall members in the drawing area based on their identifiers;

[0045] Specifically, an identification range is set in the drawing area, and all beam and wall components within the identification range are identified based on their identifiers. The beam components include frame beams, secondary beams, main rib beams, and secondary rib beams. The beam and wall components are then filtered through a component filter to obtain the filtered beam and wall components. The filtered beam components include main rib beams, and the filtered wall components include concrete interior walls, concrete exterior walls, and elevator shaft walls.

[0046] Step S106: Based on the dimensional spatial data of the beam and wall components, determine the hollow floor slab where the beam and wall components are located;

[0047] Specifically, based on the two-dimensional spatial data of the beam and wall components, the hollow floor slab containing the beam and wall components is initially determined; then, based on the three-dimensional spatial data of the beam and wall components, the initially determined hollow floor slab is verified to obtain the verified hollow floor slab.

[0048] Preferably, the AutoCAD platform's AcGe library stores 3D and 2D spatial data of drawing area components such as beams and walls, including point, line, and vector data. Then, using geometric algorithms from the AcGe library and intersection algorithms from this building quantity calculation method, hollow floor slabs that intersect or overlap with beams and walls are identified at the 2D spatial data level. Finally, the hollow floor slabs are verified based on the 3D spatial data.

[0049] Step S108: Based on the core mold components, beam components, and wall components in the hollow floor slab, determine the size and position of the gap, and then generate the gap in the drawing area.

[0050] Specifically, the width of the gap is determined based on the distance between the core mold component and the beam and / or wall components in the hollow core slab; the length of the gap is determined based on the dimensions of the beam and wall components; and the position of the gap is determined based on the position information of the core mold component. The gap is then generated in the drawing area. Furthermore, for special cases such as beam or wall components whose dimensions exceed the coverage area of ​​their respective hollow core slabs, the algorithm will handle these cases specially, generating only gaps within that specific hollow core slab, thus saving user time.

[0051] Preferably, the geometric border of the core mold is obtained using the minimum bounding box algorithm in the AcDb library. Then, the geometric borders of all core molds on the hollow floor slab are traversed to determine and combine a geometric border that can encompass all core mold components on the hollow floor slab. The distance between the core mold and the beam / wall is then determined by judging the shortest distance between this geometric border and the two-dimensional outer envelope of the beam / wall (obtaining the width of the gap). Based on the lengths of the main rib beam, the inner concrete wall, the outer concrete wall, and the elevator shaft wall, gaps of the same length are generated. In addition, at the intersection of the main rib beam or the concrete wall, the calculated length of the reinforcement in the gap is automatically deducted and the support anchorage is determined. The position of the gap is determined based on the position information of the core mold (the gap position is located between the beam / wall and the core mold).

[0052] Optionally, after step S108, the form of the gap is determined based on the position information of the core mold component in the hollow floor slab. The form of the gap includes a single-sided form and a double-sided form. The corresponding three-dimensional gap reinforcement is generated according to the form of the gap. For example, if the gap has a core mold on only one side, and a single-sided gap is selected for automatic generation, the reinforcement generated in the gap will be automatically arranged on the side with the core mold. If a double-sided gap is selected for automatic generation, the reinforcement generated in the gap will still be automatically arranged on the side with the core mold.

[0053] Through steps S102 to S108 in the embodiments of this application, the problem of low efficiency in the identification and generation of gaps in building quantity calculation is solved. It realizes that gaps do not need to be manually arranged one by one, and gaps can be automatically identified and generated on a large scale. The identification efficiency is high and it is not easy to make mistakes. The three-dimensional effect after identification and generation can more intuitively view the arrangement of steel bars.

[0054] It should be noted that the steps shown in the above process or in the flowchart of the accompanying figures can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flowchart, in some cases the steps shown or described may be executed in a different order than that shown here.
