Because the consumption of the steel bars is extremely large, the manual operation production efficiency is low, the labor intensity is high, the processing quality and the time schedule are difficult to control, the waste of materials and energy is high, the processing cost is high, and the potential safety hazard is high. Therefore, various special machines are required to be adopted for processing the steel bars, with the continuous development of manufacturing technology, the current steel bar processing is increasingly controlled by a computer, namely, the numerical control processing technology of the steel bars is used for straightening, cutting off, bending and the like, the numerical control processing technology of the steel bars is more prone to error, the determination of a steel bar detail table before processing is carried out, the prior art generally adopts BIM technology to complete the model reproduction of actual engineering, and then the corresponding BIM model is used for carrying out statistics and calculation of the steel bar detail table.
Of course, the calculation of the steel bar detail table is finished through the BIM model, for example, the corresponding steel bar BIM model and the actual engineering construction may have differences, and the actual demand and the demand calculated by the model are inconsistent due to the differences, so that the number of the steel bars processed according to the steel bar detail table cannot meet the number required by the actual engineering construction, and for the staff of the actual engineering, the staff needs to process again according to the actual missing amount, thereby not only reducing the construction efficiency and being unfavorable for the rapid progress of the engineering, but also increasing the workload of the staff.
Therefore, a BIM-based automatic processing system and method for reinforcing steel bars are needed, the problem that the concrete form of the reinforcing steel bars is inaccurate due to the fact that the BIM model of the reinforcing steel bars is different from an actual project can be solved, and the accuracy of the processing quantity of the reinforcing steel bars in the actual project use process is improved.

The principle and the advantages of the scheme are as follows: in the scheme, firstly, a BIM technology is utilized to construct a corresponding reinforcing steel bar BIM model of an actual project, the actual reduction and reproduction of the shape of the reinforcing steel bar in the actual project are realized through the model construction of the step, then, the model is utilized to count the information of each reinforcing steel bar corresponding to the whole actual project, a corresponding reinforcing steel bar detail table is generated, the obtained detail of the reinforcing steel bar is closer to reality, the reality can be more improved, the reinforcing steel bar related to the actual project can be accurately counted as much as possible, and the problems that the reinforcing steel bar is not processed in place and the corresponding quantity is not right in construction after the post-processing is completed are avoided.
Meanwhile, in order to make the steel bar detail table more real, in the scheme, a historical pre-steel bar detail table and a historical actual steel bar detail table corresponding to a model similar to the current steel bar BIM model are matched, and the difference between the steel bar information statistics of the whole system and the steel bars used in the actual engineering is formed by the historical pre-steel bar detail table and the historical actual steel bar detail table corresponding to historical data, so that whether the system needs to reserve the steel bar information statistics of the current steel bar BIM model or not is judged, and when the reservation is needed, the reserved quantity of the corresponding steel bars is calculated, and then the corresponding steel bar detail table is updated to form a new steel bar detail table.
And then, according to the new steel bar detail table, carrying out corresponding cutting and bending on each steel bar by utilizing automatic processing equipment according to the information of each steel bar in the steel bar detail table, thereby completing the processing of the steel bars.
In the scheme, the fact that the construction corresponding to the BIM model of the reinforcing steel bar and the actual engineering is considered to be possibly different is considered, the problem that part of reinforcing steel bar information is lack is caused when the construction is carried out, the situation that the field staff needs to process corresponding reinforcing steel bar information on the field is caused, the construction efficiency is greatly reduced, meanwhile, the field staff processes the lack reinforcing steel bar information, the problems of large processing difficulty, large processing quantity and the like are possibly caused, the construction difficulty and the physical loss of the staff are greatly improved, the scheme judges the error between the actual demand quantity and the model giving quantity in the current reinforcing steel bar detail by utilizing the historical model data, namely the historical reinforcing steel bar BIM model and the corresponding historical pre-reinforcing steel bar detail table and the historical actual reinforcing steel bar detail table after the corresponding reinforcing steel bar detail table is completed, and the corresponding pre-reserved quantity is calculated when the error is larger than the preset error threshold value, the automatic processing information after the reinforcing steel bar detail table can better meet the actual engineering demand quantity, and the accuracy of the reinforcing steel bar detail table can be improved when the actual engineering is not different from the actual reinforcing steel bar model.
Preferably, as a modification, the step S2 includes the steps of:
s20, judging the size of an actual project corresponding to the steel bar BIM according to the current steel bar BIM, if the actual project amount is greater than a preset project threshold, performing the next step, otherwise, executing S3;
s21, according to the current reinforcement BIM model, matching is carried out from a historical reinforcement BIM model in a database, and when a corresponding matching value reaches a preset matching value, the corresponding historical reinforcement BIM model, a historical simulation reinforcement detail table and a historical actual reinforcement detail table corresponding to the historical reinforcement BIM model are called out from the database;
s22, calculating the corresponding error value of the historical steel bar BIM model when calculating each steel bar according to the adjusted historical simulated steel bar detail table and the historical actual steel bar detail table, judging whether each corresponding error value is larger than a preset error threshold value, if so, judging that the corresponding steel bar needs to be reserved, executing the next step, and otherwise, executing S3;

and the processing module is used for cutting and bending the steel bars according to the new steel bar detail table and corresponding steel bar information in the steel bar detail table by automatic processing equipment.
Principle and effect of this scheme: in the scheme, the construction of the corresponding reinforcing steel bar BIM model is completed through the model construction module, then the data acquisition module is utilized to carry out statistics of corresponding reinforcing steel bar information according to the corresponding reinforcing steel bar BIM model, a final reinforcing steel bar detail table is generated, the fact that differences can exist between actual engineering and the reinforcing steel bar BIM model is considered, in order to avoid the problem that the corresponding reinforcing steel bar information is lack, the reinforcing steel bar BIM model, a historical pre-reinforcing steel bar detail table and a historical actual reinforcing steel bar detail table which correspond to the historical reinforcing steel bar BIM model with the similar model type are utilized to calculate and judge whether the model needs to be reserved or not, the reserved quantity is calculated when the reservation is needed, the corresponding reinforcing steel bar detail table is updated, and therefore a new reinforcing steel bar detail table is formed, and then the reinforcing steel bar is processed through the processing module.
Compared with the prior art that corresponding processing is directly carried out after the corresponding steel bar detail table is calculated by using the BIM model, the scheme fully considers that the difference possibly exists between the actual engineering and the steel bar BIM model, if the difference can not be well solved, the corresponding obtained steel bar detail table is not very accurate, then the processed steel bar information can have a lack problem during the construction of the actual engineering, the trouble is brought to on-site staff, the construction efficiency of the engineering is reduced, meanwhile, the processing difficulty is brought to the on-site processing of the steel bar, so that the problem that the construction efficiency is reduced, namely the accuracy of the concrete engineering is improved due to the fact that the BIM model is not accurate, is solved by setting the reserved calculation module, whether the steel bar information in the steel bar detail table needs to be reserved or not is judged and identified, and the reserved quantity is calculated after the identification, so that the quantity of each steel bar information in the corresponding steel bar detail table can be greatly reduced from the required quantity of the actual engineering is more accurate, and meanwhile, the problem that the on-site staff can temporarily process the construction efficiency is reduced is avoided, and the problem that the concrete engineering is not accurate when the concrete engineering is processed due to the difference exists.
Preferably, as an improvement, the reservation calculation module includes:
the first judging module is used for judging the size of the actual engineering corresponding to the model according to the current reinforcing steel bar BIM model, and if the actual engineering quantity is greater than a preset engineering threshold value, primarily judging that reinforcing steel bar information corresponding to the model needs to be reserved;
the data acquisition module is used for carrying out matching from the historical steel bar BIM model in the database according to the current steel bar BIM model when the steel bar information corresponding to the model is preliminarily judged to be reserved, and calling out the corresponding historical steel bar BIM model, the historical simulated steel bar detail table and the historical actual steel bar detail table corresponding to the historical steel bar BIM model from the database when the corresponding matching value reaches a preset matching value;
the second judging module is used for calculating the corresponding error value of the historical steel bar BIM model when calculating each steel bar according to the adjusted historical simulated steel bar detail table and the historical actual steel bar detail table, judging whether each corresponding error value is larger than a preset error threshold value, and if so, judging that the corresponding steel bar information is really needed to be reserved;
and the calculation module is used for calculating the reserved quantity of the corresponding reinforcing steel bars according to the corresponding error quantity when the judgment result is that the corresponding reinforcing steel bar information is actually needed to be reserved, and updating the corresponding reinforcing steel bar detail table to form a new reinforcing steel bar detail table.
The beneficial effects are that: in this scheme, whether reserve through twice judgement and carry out more accurate and reasonable judgement, improved the judgement degree of accuracy of whether reserving greatly, also avoided appearing reserving the judgement error like this, lead to the reinforcing bar information to appear unnecessary, causes extravagant problem.
Preferably, as an improvement, the method further comprises a third judging result, when the corresponding judging result is that the corresponding reinforcing steel bar information is needed to be reserved, extracting the reinforcing steel bar model corresponding to the reinforcing steel bar information, judging whether the diameter of the corresponding reinforcing steel bar is larger than or equal to a preset diameter threshold value, if so, judging that the judging result of the second judging module is correct, otherwise, judging that the judging result of the second judging module is inaccurate.
The beneficial effects are that: this judgement is to judging the diameter of reinforcing bar, only the corresponding reinforcing bar diameter is greater than the reservation amount of the reinforcing bar that just can calculate of preset diameter threshold value, fully consider the processing difficulty degree of reinforcing bar information through this kind of mode, like some diameters are less its corresponding processing degree of difficulty just than less, the staff of scene just can process out very easily like this, then this part reinforcing bar information just can not consider the reservation, only reserve the reinforcing bar information that those processing degree of difficulty are big, so not only make reinforcing bar information reserve more rationalized, also further avoided extravagant problem simultaneously.
Preferably, as an improvement, the model matching module is used for matching the reinforcing steel bar information sets with the same reinforcing steel bar model according to the information of each reinforcing steel bar in the reinforcing steel bar detail table, and sequencing the reinforcing steel bars from large to small according to the length of the reinforcing steel bars; the steel bar information comprises the types, the lengths, the shapes and the number of the steel bars;
the leftover material calculation module is used for sequentially calculating the length of leftover materials according to the arrangement sequence of the reinforcing steel bar information in the reinforcing steel bar information set;
the comparison module is used for judging whether the length of the leftover materials is greater than or equal to the length of the reinforcing steel bars of each reinforcing steel bar information set after the calculation of the length of each leftover material is finished, and judging that the leftover materials can be used for processing the reinforcing steel bar information if the length of the leftover materials is greater than or equal to the length of the reinforcing steel bars of each reinforcing steel bar information set;
and the processing matching module is used for matching one of the reinforcing steel bar information when the judging result is that the leftover materials can be used for processing the reinforcing steel bar information, correlating the reinforcing steel bar information corresponding to the leftover materials, adding the use of the leftover materials into the reinforcing steel bar information corresponding to the leftover materials, and calculating the matched reinforcing steel bar information when the length of the leftover materials is calculated.

Detailed Description
The following is a further detailed description of the embodiments:
an example is substantially as shown in figure 1: a BIM-based automatic processing method for reinforcing steel bars comprises the following steps:
s1, building a reinforcement BIM model corresponding to an actual project, counting corresponding reinforcement information according to the reinforcement BIM model, and generating a corresponding reinforcement detail table; in this embodiment, after the modeling of the reinforcement BIM is completed, in order to avoid reworking and material waste caused by reinforcement collision in the actual construction process, the reinforcement model needs to be subjected to collision inspection to generate a collision detection report, fine adjustment is performed on the premise of not violating the design intent, and the reinforcement model is optimized. Meanwhile, in the embodiment, in order to enable the reinforcing steel bar BIM model to be more accurate, when the model is constructed, a plurality of model software are used for constructing, and the corresponding generated reinforcing steel bar BIM model is used for carrying out comparison analysis to obtain the more accurate reinforcing steel bar BIM model. For example, two modeling software of Reit and Tekla are adopted to carry out fine modeling on the steel bar, and a more accurate steel bar model is obtained through comparative analysis of the steel bar model generated by the two modeling software.
The steps between S1 and S2 further comprise the following steps:
s120, matching the reinforcement information sets with the same reinforcement types according to the reinforcement information in the reinforcement detail table, and sorting from large to small according to the reinforcement length; the steel bar information comprises the types, the lengths, the shapes and the number of the steel bars;
s121, sequentially calculating the lengths of the scraps according to the arrangement sequence of the reinforcing steel bar information in the reinforcing steel bar information set;
s122, after the calculation of the length of each piece of leftover material is completed, judging whether the length of the leftover material is greater than or equal to the length of the steel bar of each piece of steel bar information in the set of steel bar information, and if so, judging that the leftover material can be used for processing the steel bar information;

For example, the corresponding reinforcement information set of a certain model includes A, B, C, wherein the reinforcement length of the reinforcement information a is a, the reinforcement length of the reinforcement information B is B, the reinforcement length of the reinforcement information C is C, and the length of the complete reinforcement to be processed is d, wherein a > C > B; firstly, sorting the information of the reinforcing steel bars from big to small, namely A, C, B; then, the calculation of the leftover materials is performed according to the sequence of A, C, B, when the calculation is performed on A, only two pieces of A can be obtained for each complete reinforcing steel bar, then the corresponding leftover material is d-2a, the length of the leftover material is compared with the length of C, B, and if d-2a > c > b is assumed, the leftover materials can be used for processing at the judgment C, B, and then one piece of the leftover material can be selected as an object for processing the leftover materials.
The calculation of the leftover materials is carried out on the long steel bar information, so that the fact that some long steel bar information is not well matched with the leftover materials is considered, the utilization rate of the leftover materials is greatly improved, the waste of the leftover materials is avoided, and the reasonable utilization of the leftover materials is realized.
