Description

[0001] The invention relates to the technical field of construction engineering, and in particular to a method for finely modeling steel bars for modeling through-arrangement of surface and intermediate bars of an equipment foundation. Background Art

[0002] At present, with the development of the socialist market economy, the engineering cost industry has received more and more attention, which is reflected in all aspects of social economy and life. That is, the engineering cost has received unprecedented attention from government-invested projects, enterprise-invested projects, foreign-funded projects, individual investment projects and engineering contractors. At this stage, whether it is investment estimation, budget, budget, or settlement, they are all closely related to "project quantity", and there is no engineering cost that can exist independently of "project quantity". Therefore, in order to determine and control the engineering cost, it is necessary to pay strong attention to the extremely important basic quantity calculation work in engineering cost management. In the context of the vigorous development of BIM technology application, the integration of traditional engineering cost and BIM technology is the general trend and a necessary condition for fine engineering quantity calculation.

[0003] At present, various types of BIM modeling and quantity calculation software on the market are in a state of contention, and they are mainly developed and optimized for housing construction projects. In addition, due to the problems of software technology development or the lack of in-depth understanding of relevant professional engineering specifications and rules by software engineers, the development of BIM modeling software functions for such professional projects is not thorough enough and cannot meet the actual use requirements of project participants.

[0004] Due to the limitation of software calculation rules, the software can only complete regular bending calculations, and cannot complete the end bending calculations of multiple elevations and multiple lengths at the same time. Some end bending steel bar engineering quantities can only be completed by manual calculation. The manual calculation process of engineering quantities is very cumbersome. The data of steel bars, templates, and concrete need to be calculated repeatedly to complete the engineering quantity calculation, which leads to omissions or repeated calculations, resulting in loss of engineering quantities and large losses to the company. At the same time, the manual calculation cycle is relatively long, and due to differences in the calculation process of each person's thinking, disputes in the internal and external settlement audit process continue, and even one-on-one verification and recalculation with the auditor are required. The manual calculation of engineering quantities is far from meeting the needs and has been replaced by BIM computer software.

[0005] However, in traditional BIM calculation, the ends of the reinforcement are bent downward to form a standard connection with the bottom stress reinforcement. Figure 1 The uneven elevations of the middle reinforcements and the inability to form a connection with the surface reinforcements result in a huge difference between the reinforcement in the traditional BIM model and the structure in the drawings, which fails to meet the design requirements. At the same time, it leads to poor calculation quality and low work efficiency. Summary of the invention

[0057] S1032. Draw an auxiliary basic element at the side wall edge of the original top elevation H in the new basic element.

[0058] S1033. Summarize the calculations and find that the end of the top stress-bearing reinforcement at the original top elevation H is bent downward and anchored to the bottom of the foundation when it meets the auxiliary foundation element, forming a structural connection with the bottom stress-bearing reinforcement.

[0059] Specifically, the calculation is summarized and the end of the stressed steel bar at the top of the original top elevation H is bent downward to meet the auxiliary foundation element to form a standard anchorage of 35*d.

Provide technical support for the construction and data information management (BIM) platform.

[0067] The following describes the refined modeling method for the downward bending of the top reinforcement ends of the induced draft fan foundation at multiple elevations.

[0068] Continue to refer to Figures 3 to 9 The induced draft fan foundation is composed of an upper and lower structure, with a bottom elevation of -2.300m and a top elevation of -0.300m, 0.600m, 2.720m, and 3.290m. Figures 5 to 7 The middle reinforcement of one layer is connected, the -0.30m stress-bearing steel bar (surface reinforcement) is bent downward to the bottom of the foundation to form a standard connection with the bottom stress-bearing steel bar (bottom reinforcement), the middle reinforcement is connected with the surface reinforcement, and the end of the middle reinforcement is not bent, see Figures 5 to 7 .

[0069] Step 1: Adjust the basic primitives

[0070] 1. Draw basic elements of different elevations according to different elevations. The bottom elevation is -2.300m, and the top elevations are -0.300m, 0.600m, 2.7200m, and 3.2900m respectively. Figure 8 .

[0071] 2. Adjust the top elevations to -0.300m and the bottom elevations to different heights to form a new basic element. Fig.10 .

[0072] 3. The top elevation of the through arrangement is -0.300m. The stress steel bar (rebar) c12@150, and the bend of the rebar end is adjusted to 0. Fig.11 ; Then, the calculation is summarized to form -0.300m through steel bar, see Fig.12 .

[0073] It should be noted that C12@150, where C represents the grade of steel bars and @ represents the spacing between steel bars, C12@150 is grade three steel bars with 12 circles and a spacing of 150mm.

[0074] Step 2: Original top elevation - 0.300m Top stress reinforcement foundation end bending adjustment

[0075] 1. Create a new foundation component: Edit the properties of the auxiliary foundation element (i.e. FB-1 (auxiliary foundation) element), the bottom elevation is -2.300m, the thickness of the auxiliary foundation element is equal to the length of the downward bent steel bar anchorage, see Fig.13 .

[0076] 2. Draw auxiliary foundation elements at the edge of the side wall at the original top elevation -0.300m and bottom elevation -2.300m in the new foundation element, see Fig.14 .

[0077] 3. Summarize the calculation and find that the end of the stress-bearing steel bar at the top of the original top elevation -0.300m is bent downward and meets the auxiliary foundation element to form a standard anchorage of 35*d.

[0078] 4. Lock the top stress reinforcement and delete the FB-1 (auxiliary foundation) element, see Fig.15 .

[0079] 5. The bottom elevation of the basic element is adjusted to -2.300m, and the top of the basic element will be restored to -0.300m, 0.600m, 2.7200m, and 3.2900m, see Fig.16 .

[0080] 6. Draw and calculate the top stress reinforcement. The middle reinforcement of the surface reinforcement is connected. The -0.300m surface reinforcement is bent downward to the bottom of the foundation to form a structural connection with the bottom stress reinforcement. Among them, the bending of the middle reinforcement end is zero, so that the reinforcement meets the design structure requirements consistent with the drawings. See Fig.17 .

[0081] The present application provides a method for fine-grained modeling of steel bars for modeling the through-arrangement of surface and middle bars of equipment foundation, comprising the following steps: adjusting the basic graphic element so that each top elevation is consistent with the elevation of the surface bar to form a new basic graphic element, wherein the surface bar is the top stressed steel bar with a top elevation of H; summarizing the calculation to form the through steel bar at the elevation H; adjusting the bending of the basic end of the stressed steel bar at the top of the top elevation H; locking the top stressed steel bar and restoring the original elevation; drawing and calculating the top stressed steel bar to form the surface and middle bars through; compared with traditional BIM computer calculation, the surface and middle bars can be connected to meet the design requirements; at the same time, the calculation quality and work efficiency are improved.
