Description

Technical Field

[0001] The present invention relates to the field of computer-aided design, and in particular to a steel bar sample drawing method, device, equipment and storage medium based on a civil air defense door frame wall. Background Art

[0002] Civil air defense projects, also known as civil air defense fortifications, refer to underground protective buildings built separately to ensure the shelter of personnel and materials, civil air defense command, and medical rescue during wartime. Among them, the civil air defense door frame wall, as a protective unit in the civil air defense project, is actually a wall around the door hole that ensures the door leaf is in place and bears the load transmitted by the door leaf. During the construction process of the civil air defense door frame wall, the layout and installation of the steel bars that make up the structure will be involved, and the steel bars that need to be installed will be counted to facilitate on-site construction cutting and installation.

[0003] There are two methods of rebar turning for civil air defense door frame walls in the prior art, specifically:

[0004] One is to create a model of the civil air defense door frame wall through the quantity calculation software, and summarize and output the steel bars contained in the model. The steel bar algorithm only achieves the total budget accuracy, and cannot output the steel bars of the upper structure / lower structure / left structure / right structure separately to meet the installation sequence requirements of "first tie the lower structure and the left and right side inserted bars, and then install the upper structure and the left and right side connecting bars" on site. At the same time, when calculating the steel bars, the end protection layer avoidance of the upper and lower structures and the left and right side structures, the thickness of the additional protection layer on the inside of the left and right structures when the door frame is installed, and other on-site construction requirements are not considered. The obtained steel bar budget is relatively rough and cannot be cut and installed on site. That is, when cutting materials on site, the obtained steel bar information needs to be further analyzed and calculated to obtain the steel bar quantity of specific parts of the civil air defense door frame wall.

[0005] Another way is to use the template drawing tool software, that is, to draw up the steel bars according to the relevant drawings required by the construction site of the door frame wall. However, this method calculates the steel bars according to independent structures, and cannot automatically consider the anchorage and overlap relationships between different structures. In addition, the steel bars are not calculated based on the construction BIM engineering model, and the calculation settings and node settings in the construction drawing set cannot be comprehensively considered, nor can the relationship between the door frame wall and the column and wall steel bars be automatically determined. Therefore, the calculated amount of steel bars cannot meet the actual construction requirements, and construction personnel need to perform additional analysis, which increases labor costs.

[0006] The above two methods do not take into account the node relationship between different structures when calculating the steel bars of the civil air defense door frame wall, resulting in low calculation accuracy. At the same time, the steel bar material list is not output by structure, which cannot meet the on-site construction requirements.

[0007] There is currently no effective solution to the technical problems that the existing human frame wall reinforcement calculation method has low accuracy and cannot meet on-site construction requirements. Summary of the invention

[0008] The purpose of the present invention is to provide a method, device, equipment and storage medium for rebar drawing based on civil air defense door frame wall, which can solve the technical problems of low accuracy of the calculation method of the reinforcement of the civil air defense door frame wall and failure to meet the requirements of on-site construction.

[0031] Embodiment 1

[0032] This embodiment provides a method for rebar drawing based on civil air defense door frame wall. Figure 1 The flowchart of the steel bar re-drawing method based on the civil air defense door frame wall is shown as follows: Figure 1 As shown, the steel bar drawing method based on the civil air defense door frame wall may include steps S1 to S4, wherein:

[0033] Step S1, obtaining the BIM model of the civil air defense door frame wall, wherein the BIM model includes multiple door frame wall sub-structures.

[0034] The BIM model of the civil air defense door frame wall can be created from conventional BIM software, or it can be regenerated by importing the calculated steel bar model. The BIM model of the civil air defense door frame wall includes multiple door frame wall sub-structures, which can be: left structure, right structure, upper structure, and lower structure.

[0035] Step S2, respectively extracting each door frame wall substructure of the BIM model and the preset steel bar structure information associated with the door frame wall substructure, constructing the door frame wall substructure in three dimensions according to the associated preset steel bar structure information, and generating the initial steel bar structure of each door frame wall substructure.

[0036] Based on the created door frame wall sub-structure, the reinforcement information of the left structure, right structure, upper structure and lower structure is input according to user needs, and part of the input reinforcement information is used as the preset reinforcement structure information. The corresponding door frame wall sub-structures are separately constructed in three dimensions through the preset reinforcement structure information to generate the initial reinforcement structure of each door frame wall sub-structure, which is convenient for the subsequent on-site construction of reinforcement cutting and installation.

[0037] The preset steel bar structure information may include steel bar cross-sectional shape, longitudinal bar information (longitudinal bar specifications, spacing, etc.), stirrup information, tension bar information, opening reinforcement bar information, and protective layer thickness information. It may also include algorithm settings (such as longitudinal bar stagger percentage, stirrup hook angle, etc.) and node settings (such as foundation dowel bar nodes, etc.).

[0038] Step S3, obtaining preset reinforcement adjustment information associated with the door frame wall structure, adjusting the generated initial reinforcement structure according to the preset reinforcement adjustment information, and obtaining an adjusted reinforcement structure.

[0039] The obtained initial steel bar structure is only the creation of the basic layout of steel bars. For example, the spacing or specification settings of adjacent steel bars do not meet the construction requirements and specifications of the actual building structure and cannot be directly used in the actual construction cutting plan. The generated initial steel bar structure is adjusted by pre-setting the steel bar adjustment information to reset the unreasonable parameters in the initial steel bar structure and obtain the adjusted steel bar structure for the actual steel bar cutting plan.

[0040] The preset reinforcement adjustment parameters can be obtained by combining the historical creation data of the civil air defense door frame wall, or by real-time input by the user according to the on-site construction situation. Among them, the preset reinforcement adjustment information includes reinforcement layout parameters and additional protection layer parameters.

[0041] Furthermore, the generated initial steel bar structure is adjusted according to the preset steel bar adjustment information to obtain the adjusted steel bar structure, including: determining the two-dimensional cross-sectional properties of the initial steel bar structure to be extracted according to the category of the door frame wall structure, and adjusting the two-dimensional cross-sectional properties according to the steel bar layout parameters and the additional protective layer parameters.

[0042] The layout of the steel bars in each door frame wall structure will vary due to differences in function. Therefore, for the different types of steel bars in each door frame wall structure, it is necessary to extract the two-dimensional cross-sectional view that presents the most comprehensive effect of the corresponding steel bar structure for adjustment. At the same time, for each two-dimensional cross-sectional view, the steel bar layout parameters or additional protective layer parameters are used to achieve targeted processing of the corresponding steel bars in each door frame wall structure to improve the accuracy of the steel bar layout. Furthermore, the two-dimensional cross-sectional view is a visual perspective of the steel bar structure in the initial steel bar structure. In the process of adjusting the steel bar information in the two-dimensional cross-sectional view, the steel bar information in the three-dimensional model of the initial steel bar structure will also be adaptively adjusted to ensure the overall accuracy of the initial steel bar structure, thereby obtaining the target steel bar structure of the door frame wall structure.

[0043] Furthermore, the categories to which the door frame wall structure belongs may include door post structure (also called left and right structure) and door beam structure (also called upper and lower structure), the left side structure and the right side structure belong to the door post structure, and the upper structure and the lower structure belong to the door beam structure; the two-dimensional cross-sectional view may include a front cross-sectional view, a top cross-sectional view and a side cross-sectional view.

[0044] Furthermore, the properties of the two-dimensional cross-sectional view of the initial steel bar structure to be extracted are determined according to the category of the door frame wall structure, and the two-dimensional cross-sectional view with the determined properties is adjusted according to the steel bar layout parameters and the additional protective layer parameters, including steps A1 to A3:

[0045] Step A1, if the door frame wall structure belongs to the left and right structure, determine that the two-dimensional cross-sectional properties of the initial steel bar structure to be extracted are the main cross-sectional view, the top cross-sectional view and the side cross-sectional view;

[0046] Step A2, adjusting the reinforcement information of the main section view according to the reinforcement layout parameters.

[0047] Optionally, step A2 may include steps A21 to A22, wherein:

[0048] Step A21, obtaining the arrangement of stirrups in the reinforcement layout parameters, and determining the calculation starting node of the stirrups in the main view section through the arrangement.

[0049] The arrangement of stirrups can be "arranged along the height of the opening" and "calculated along the full height of the door frame wall". If the arrangement is "arranged along the height of the opening", the lower boundary line of the opening (i.e. the door frame, the same meaning below) will be used as the calculation starting node of the stirrups in the main section view; if the arrangement is "calculated along the full height of the door frame wall", the protective layer boundary line of the lower adjacent wall structure of the left and right structures will be used as the calculation starting node of the stirrups in the main section view.

[0050] Step A22, obtaining the stirrup spacing and starting distance in the reinforcement layout parameters, and adjusting the layout of the stirrups in the main cross-sectional view by calculating the starting node, stirrup spacing and starting distance.

[0051] When arranging stirrups based on the main section view,

[0052] If the arrangement method is "arrange along the height of the opening", the position of the first stirrup is calculated by calculating the starting node and the starting distance. Taking the position of the first stirrup as the reference, other stirrups are arranged upward according to the stirrup spacing. When the position of a stirrup exceeds the upper boundary line of the opening, the distance between the next adjacent stirrup of the stirrup and the upper boundary line of the opening is calculated. If the distance is greater than or equal to the first preset threshold, the stirrup is arranged at the height of the upper boundary line of the opening, and all stirrups located above the stirrup and belonging to the same door frame wall structure are removed; if the distance is less than the first preset threshold, the stirrup and all stirrups located above it and belonging to the same door frame wall structure are removed, where the first preset threshold can be 1 / 2 of the stirrup spacing.

[0053] If the layout method is "calculated along the full height of the door frame wall", the stirrups are arranged based on the calculation starting node according to the order of stirrup spacing. The stirrups are selected based on the relative distance between their positions and the upper boundary line of the door frame wall structure. The selection principle is the same as the application scenario where the layout method is "arranged along the height of the opening", so it will not be repeated here.

[0054] Step A3: adjusting the reinforcement information of the top view and the side view according to the additional protection layer parameters.

[0055] Further, step A3 may include steps A31 to A32, wherein:

[0056] Step A31, obtaining the thickness of the inner protective layer in the additional protective layer, and adjusting the side length of the stirrups, tension bars and longitudinal bars in the top view according to the thickness of the inner protective layer.

[0057] The side lengths of the stirrups of the left and right structures are shrunk by the "inner protective layer thickness" of the left and right structures. At the same time, based on the adjusted stirrup side lengths, it is judged whether the number of tension bars and longitudinal bars in the top view section view meets the actual construction requirements. If the distance between the tension bars and longitudinal bars close to the inner protective layer and the adjacent tension bars and longitudinal bars is greater than or equal to the second preset threshold, the original number of tension bars and longitudinal bars in the top view section view is retained; if the distance between the tension bars and longitudinal bars close to the inner protective layer and the adjacent tension bars and longitudinal bars is less than the second preset threshold, the number of tension bars and longitudinal bars in the top view section view is reduced; wherein the second preset threshold can be 1 / 2 of the tension bar spacing. The top view section layout of the stirrups of the left and right structures is as follows: Figure 2 shown.

[0058] Step A32, obtaining the end protection layer thickness of the additional protection layer parameters, and adjusting it by the bending length of the inserted reinforcement in the side view cross-section of the end protection layer thickness.

[0059] According to the "end protection layer distance" of the left and right structural dowels, the vertical length of the dowels is reduced while the straight length of the left and right dowels is increased to meet the need to avoid the steel bars at the bottom of the raft slab on site. The side view cross-section layout of the left and right structural dowels is as follows: Figure 3 shown.

[0060] Furthermore, the properties of the two-dimensional cross-sectional view of the initial steel bar structure to be extracted are determined according to the category of the door frame wall substructure, and the two-dimensional cross-sectional view with the determined properties is adjusted according to the steel bar layout parameters and the additional protective layer parameters, including steps B1 to B3:

[0061] Step B1, if the door frame wall structure belongs to the upper and lower structure, determine that the two-dimensional cross-sectional view attributes of the initial steel bar structure to be extracted are the top cross-sectional view and the side cross-sectional view;

[0062] Step B2, adjusting the steel bar information of the top view cross-section according to the steel bar layout parameters.

[0063] Further, step B2 may include steps B21 to B22, wherein:

[0064] Step B21, obtaining the anchorage length of the longitudinal reinforcement in the reinforcement layout parameters and the adjacent wall structure of the door frame wall structure;

[0065] Step B22, adjusting the layout of the longitudinal reinforcement information in the top view according to the interactive relationship between the anchorage length of the longitudinal reinforcement and the adjacent wall structure.

[0066] In the top view cross-section of the door frame wall structure of the upper and lower structures, extract the wall thickness of the adjacent column wall structure contained in the top view cross-section, compare the values ​​of the longitudinal reinforcement anchorage length and the wall thickness, if the longitudinal reinforcement anchorage length is less than or equal to the wall thickness, then calculate the extended anchorage length (expressed in laf) from the inner side of the upper and lower structures and set it to a straight anchor form (such as Figure 4 (a)); if the anchorage length of the longitudinal reinforcement is greater than the wall thickness, the anchorage length of the longitudinal reinforcement is determined by the adjacent wall structure of the beam-slab structure to determine whether the anchorage length of the longitudinal reinforcement exceeds the distance from the protective layer of the adjacent wall structure to the outermost boundary line of the beam-slab structure. If so, the longitudinal reinforcement is bent according to the excess length (such as Figure 4 If not, set the longitudinal reinforcement to straight anchor type.

[0067] Step B3, adjusting the reinforcement information of the side view section according to the additional cover parameters.

[0068] Further, step B3 may include step B31 to step B32, wherein:

[0069] Step B31, obtaining the bottom protective layer thickness of the additional protective layer parameter, and adjusting the side length of the stirrup in the side cross-sectional view according to the bottom protective layer thickness;

[0070] Step B32, making corresponding adjustments to the tension bars and longitudinal bars in the side section view according to the adjusted stirrup side lengths.

[0071] The side length of the stirrups of the lower structure is shrunk by using the "inner protective layer thickness" of the lower structure. At the same time, based on the adjusted side length of the stirrups, it is judged whether the number of tension bars and longitudinal bars in the side section view meets the actual construction requirements. If the distance between the tension bars and longitudinal bars close to the inner protective layer and the adjacent tension bars and longitudinal bars is greater than or equal to a second preset threshold, the original number of tension bars and longitudinal bars in the side section view is retained; if the distance between the tension bars and longitudinal bars close to the inner protective layer and the adjacent tension bars and longitudinal bars is less than the second preset threshold, the number of tension bars and longitudinal bars in the side section view is reduced.

[0072] Step S4, classify and count the steel bar information of the adjusted steel bar structure of each door frame wall sub-structure, and generate a steel bar cutting list for each door frame wall sub-structure to complete the steel bar drawing of the civil air defense door frame wall.

[0073] The re-drawing generally refers to the calculation of materials and labor in the steel bar project. The re-drawing personnel calculate the steel bar budget and cutting data according to the drawings, which are used for the bidding, material purchase, on-site construction and final settlement of the project. In this embodiment, the steel bar re-drawing of the civil air defense door frame wall can be realized by statistically analyzing the steel bar information of the adjusted steel bar structure.

[0074] Further, step S4 may include steps S41 to S42, wherein:

[0075] Step S41, for each door frame wall substructure, the steel bars included in the adjusted steel bar structure are grouped according to their categories to generate a plurality of steel bar sets.

[0076] Among them, when the door frame wall structure is a left-right structure, the categories of steel bars may include connecting bars, inserted bars, stirrups, and tension bars; when the door frame wall structure is an up-and-down structure, the categories of steel bars may include longitudinal bars, stirrups, tension bars, and opening reinforcement bars.

[0077] Step S42, classify and summarize the steel bars in each steel bar set according to the steel bar length and steel bar specification, and sequentially record the summary results of the steel bar set according to the preset steel bar output order to generate a steel bar cutting list for the door frame wall structure.

[0078] Output the steel bar blanking list according to the door frame wall structural information and the corresponding steel bar information. The preset steel bar output order can include the door frame wall structural component sorting and steel bar sorting, where the door frame wall structural component sorting is: left structure > right structure > lower structure > upper structure. Steel bar sorting: (a) Left and right side structural steel bar order: connecting bar > inserted bar > stirrup > tension bar, (b) upper and lower structural steel bar order: longitudinal bar > stirrup > tension bar > opening reinforcement bar.

[0079] In addition, when outputting the steel bar cutting list, the adjusted steel bar structure corresponding to the door frame wall structure will be output accordingly as a reference for on-site construction cutting and installation.

[0080] In this embodiment, the BIM model of the civil air defense door frame wall is first obtained, and the adjusted steel bar structure is generated by separately laying out and adjusting the steel bar structure of the door frame wall substructure in the BIM model, and the steel bar information of the adjusted steel bar structure is separately output to be associated with the actual construction stage to meet the actual construction needs. The door frame wall fine-grained steel bar setting and adjustment capabilities based on the construction BIM model can meet various construction scenarios. At the same time, the door frame wall model is split into multiple door frame wall substructures for targeted processing to ensure the accuracy of the steel bar discharge and cutting scheme, and at the same time improve the efficiency of the steel bar sample drawing of the civil air defense door frame wall. Based on this application, the technical problems of low accuracy of the steel bar calculation method of the human frame wall and the inability to meet the requirements of on-site construction are solved. The door frame wall model is split into multiple door frame wall substructures for targeted processing to ensure the accuracy of the steel bar discharge and cutting scheme, and at the same time improve the efficiency of the steel bar sample drawing of the civil air defense door frame wall.
