Description

Technical Field

[0001] The invention relates to the technical field of construction engineering, and in particular to a refined modeling method for downward bending of the ends of top ribs at multiple elevations 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 is very cumbersome. The steel bar, formwork, and concrete data need to be repeatedly calculated 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 everyone's thinking and calculation process, disputes continue in the internal and external settlement audit process, and even one-on-one verification and recalculation with the auditor is required. Summary of the invention

[0005] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a refined modeling method for the downward bending of the ends of the top ribs of multiple elevations of an equipment foundation, which has the advantages of being able to avoid omissions and repeated calculations, shortening the engineering quantity calculation cycle, improving the calculation quality, and avoiding the loss of engineering quantities and materials, laying a solid foundation for the quantity work in the later settlement of progress reports.

[0055] Wherein, S101, in the foundation element with the bottom elevation L, the top elevation is H, and the auxiliary component wall element is drawn. The end of the first top stress-bearing steel bar meets the auxiliary component wall element and is bent downward to the bottom of the foundation to form a structural connection with the bottom stress-bearing steel bar, including:

[0056] S1011. Edit the properties of the auxiliary component wall element.

[0057] Specifically, when editing the properties of the auxiliary component wall element, the reinforcement properties are not edited.

[0058] S1012. Draw auxiliary component wall elements symmetrically on the outer edge at the top elevation H in the basic element.

[0059] S1013. Adjust the downward bending length of the first top stress-bearing steel bar end when it meets the auxiliary component wall element. The first top stress-bearing steel bar end bends downward when it meets the auxiliary component wall element to the bottom of the foundation to form a structural connection with the bottom stress-bearing steel bar.

[0060] Among them, the downward bending length of the end of the first top stressed steel bar when encountering the auxiliary component wall element is: D=H+LG.

[0061] Where D is the downward bending length of the end of the first top stressed steel bar when it encounters the auxiliary component wall element, in m; G is the thickness of the protective layer, in m; H is the top elevation, in m; L is the bottom elevation, in m.

[0062] S102, and / or draw an auxiliary component beam element at the top elevation B in the foundation element, and the end of the second top stress-bearing steel bar meets the auxiliary component beam element and bends downward to the bottom of the foundation to form a structural connection with the bottom stress-bearing steel bar, wherein B is an arbitrary number, and the unit is m.

[0063] Among them, S102, in the foundation element, the top elevation is all at B, and the auxiliary component beam element is drawn. The end of the second top stress-bearing steel bar meets the auxiliary component beam element and is bent downward to the bottom of the foundation to form a structural connection with the bottom stress-bearing steel bar, including:

[0064] S1021. Edit the properties of the auxiliary component beam element.

[0065] Specifically, when editing the properties of the auxiliary component beam element, the reinforcement properties are not edited.

[0066] S1022. Draw the auxiliary component beam element symmetrically on the outer edge at the top elevation B in the basic element.

[0067] S1023. Adjust the downward bending length of the second top stress-bearing steel bar end when it meets the auxiliary component beam element. The second top stress-bearing steel bar end bends downward when it meets the auxiliary component beam element to the bottom of the foundation to form a structural connection with the bottom stress-bearing steel bar.

[0068] Among them, the bending length of the second top stress-bearing steel bar end when it meets the auxiliary component beam element is: E=B+LG

[0069] In the formula, B is the downward bending length of the end of the second top stressed steel bar when it encounters the auxiliary component beam element, in m; G is the thickness of the protective layer, in m; B is the top elevation, in m.

[0070] S103, and / or draw an auxiliary foundation element at the edge where the top elevation of the foundation element is F, and the end of the third top stress-bearing steel bar is bent downward and anchored downward to the bottom of the foundation when it meets the auxiliary foundation element to form a structural connection with the bottom stress-bearing steel bar, wherein F is an arbitrary number and the unit is m.

[0071] Among them, S103, an auxiliary foundation element is drawn at the edge of the foundation element with the top elevation of F, and the end of the third top stress-bearing steel bar is bent downward to meet the auxiliary foundation element and anchored downward to the bottom of the foundation to form a structural connection with the bottom stress-bearing steel bar, including:

[0072] S1031. Edit the properties of the auxiliary basic graphic elements.

[0073] Among them, the thickness of the auxiliary basic element is equal to the anchor length La.

[0074] S1032. Draw an auxiliary basic primitive at the edge of the top elevation F in the basic primitive.

[0075] S1033. The end of the third top stress-bearing steel bar at the top elevation F is bent downward and anchored downward to the bottom of the foundation when it meets the auxiliary foundation element, forming a structural connection with the bottom stress-bearing steel bars.

[0076] S104. Summarize the calculations to obtain multiple elevations of top stress-bearing steel bars, which are bent downward to the bottom of the foundation to form a structural connection with the bottom stress-bearing steel bars.

[0077] Furthermore, in this embodiment, the widths of the auxiliary component wall element, the auxiliary component beam element, and the auxiliary foundation element are all smaller than the thickness of the protective layer by a preset value.

[0078] The preset value ranges from 8 mm to 15 mm. In this embodiment, the preset value is 10 mm.

[0079] In order to avoid deducting the stress-bearing steel bars in the overlapping parts of the auxiliary elements and the basic elements, the widths of the auxiliary component wall elements, auxiliary component beam elements and auxiliary basic elements are 10mm smaller than the thickness of the protective layer.

[0080] Furthermore, the refined modeling method for the downward bending of the ends of the top reinforcement at multiple elevations of the equipment foundation provided in this embodiment is to combine and model the auxiliary component wall elements, auxiliary component beam elements and / or auxiliary foundation elements so that the ends of the top stressed steel bars at different elevations are bent downward to the bottom of the foundation to form a structural connection with the bottom stressed steel bars, so that the structural form of the stressed steel bars is consistent with the drawings.

[0081] Specifically, the software makes full use of the connection relationship between the auxiliary component elements, combines the auxiliary component elements of different structures for modeling, bends the top stress-bearing steel bars of different elevations downward to the bottom of the foundation, and forms a structural connection of 150mm with the bottom stress-bearing steel bars, so that the structural form of the stress-bearing steel bars is completely consistent with the drawings and meets the design requirements.

[0082] It should be noted that the stress-bearing steel bars are composed of bottom bars, surface bars and middle bars. The structural form of the stress-bearing steel bars is relatively complex. The end of the top surface bar is bent downward to the bottom of the foundation to form a structural connection of 150mm with the bottom stress-bearing steel bars.

[0083] 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.

[0084] Continue to refer to Figures 2 to 6 Among them, the induced draft fan foundation is 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 respectively.

[0085] Step 1:

[0086] 1. Create a new component: Edit the properties of the auxiliary component wall element (i.e. Q-1 auxiliary), with the top elevation of 3.2900m and the bottom elevation of -2.300m. Do not edit the steel bar properties. Figure 7 .

[0087] 2. Draw auxiliary component wall elements symmetrically on the outer edge of the top elevation of the basic element at 3.2900m, see Figure 8 .

[0088] 3. Adjust the downward bending length of the first top stress-bearing steel bar end when it meets the auxiliary component wall element (i.e. top elevation 3.2900m + bottom elevation -2.300m - protective layer thickness 0.070m), refer to Fig. 9 ; The first top stress-bearing steel bar bends downward to the bottom of the foundation when it encounters the auxiliary component wall element, forming a structural connection with the bottom stress-bearing steel bar. Fig.10 .

[0089] Step 2:

[0090] 1. Create a new component: Edit the properties of the auxiliary component beam element (L-1 (auxiliary)), the top elevation is 2.720m, and do not edit the steel bar properties. Fig.11 .

[0091] 2. Draw the auxiliary component beam element symmetrically on the outer edge of the top elevation of the foundation element at 2.720m, see Fig.12 .

[0092] 3. Adjust the downward bending length of the second top stress-bearing steel bar end when it meets the auxiliary component beam element (i.e. top elevation 2.72m + bottom elevation -2.300m - protective layer thickness 0.070m), refer to Fig.13 ; The second top stress-bearing steel bar meets the auxiliary component beam element and bends downward to the bottom of the foundation to form a structural connection with the bottom stress-bearing steel bar. Fig.14 .

[0093] Step 3:

[0094] 1. Create a new component: Edit the properties of the auxiliary foundation element (FB-1 (auxiliary foundation)), bottom elevation -2.300m, top elevation -0.300m or 0.600m, the thickness of the auxiliary foundation element is equal to the anchor length La, see Fig.15 .

[0095] 2. Draw auxiliary basic elements at the edge of the top elevation of the basic element at -0.300m or 0.600m.

[0096] 3. At -0.300m or 0.600m, the third top stress-bearing steel bar is bent downward and anchored to the bottom of the foundation to form a structural connection with the bottom stress-bearing steel bar. Fig.16 and Fig.17 .

[0097] Step 4:

[0098] Summary calculation: The top stress-bearing steel bars of the multi-elevation plane are bent downward to the bottom of the foundation to form a structural connection with the bottom stress-bearing steel bars. Fig.18 .

[0099] The present application provides a refined modeling method for bending the ends of the top reinforcements of the equipment foundation at multiple elevations, comprising the following steps: drawing an auxiliary component wall element at a top elevation of H in the foundation element with a bottom elevation of L, and the end of the first top stress-bearing steel bar meets the auxiliary component wall element and bends downward to the bottom of the foundation to form a structural connection with the bottom stress-bearing steel bar; and / or drawing an auxiliary component beam element at a top elevation of B in the foundation element, and the end of the second top stress-bearing steel bar meets the auxiliary component beam element and bends downward to the bottom of the foundation to form a structural connection with the bottom stress-bearing steel bar; and / or The auxiliary foundation element is drawn on the edge of the top elevation F. The end of the third top stress-bearing steel bar is bent downward and anchored to the bottom of the foundation to form a structural connection with the bottom stress-bearing steel bar when it meets the auxiliary foundation element. The top stress-bearing steel bars with multiple elevations are calculated and bent downward to the bottom of the foundation to form a structural connection with the bottom stress-bearing steel bar. Compared with the traditional manual calculation mode, it avoids omissions and repeated calculations, shortens the engineering quantity calculation cycle, improves the calculation quality, avoids the loss of engineering quantity and materials, and lays a solid foundation for the quantity work of the later settlement of the progress report. At the same time, it provides modeling ideas for software development. Provide technical support for the construction and data information management (BIM) platform.
