Of course, the manner of generating the three-dimensional model of the rebar is not limited to that described above, and may be generated in other ways.
The construction BIM model can be obtained by manually modeling on the electronic equipment by a user, can be obtained by modeling the electronic equipment through CAD recognition, can be obtained by importing the GTJ model into the electronic equipment, and the like. The method for acquiring the construction BIM model by the electronic equipment is not limited, and the method can be set correspondingly according to actual requirements.

The steel bar arrangement pattern is a two-dimensional data line of the steel bars, and in the three-dimensional model of the steel bars, each steel bar line is represented in a three-dimensional line mode of the steel bars, so that the three-dimensional line of the steel bars is required to be mapped into the two-dimensional data line, and the association relationship between the three-dimensional model of the steel bars and the steel bar arrangement pattern is determined to generate the steel bar arrangement pattern. Based on the above, the association relationship may be determined by using a coordinate conversion manner or a projection manner, and accordingly, the electronic device may generate the rebar layout diagram by using a coordinate conversion manner, may generate the rebar layout diagram by using a projection manner, or may generate the rebar layout diagram by using other manners, and so on.

S22, generating a steel bar arrangement diagram based on the steel bar three-dimensional model and determining the association relation between the steel bar three-dimensional model and the steel bar arrangement diagram.
Specifically, the step S22 may include:
s221, obtaining BIM model primitives.
The electronic device obtains a BIM model, wherein the three-dimensional model of the reinforcing steel bar is attached to the primitives of the BIM model. That is, after the electronic device obtains the BIM model, the selection of BIM model primitives may be provided. Specifically, the user may make a box selection, or click, etc. in the BIM model. Accordingly, the electronic device may obtain the BIM model primitive.
Or the electronic device may directly determine the primitive in the primitive list corresponding to the current component type of the current layer as the BIM model primitive; alternatively, the electronic device may determine the BIM model primitive in other ways.
In some optional implementations of this embodiment, as shown in fig. 4, S221 may include:
(1) Judging whether an arrangement range is selected or not;
when the arrangement range is not selected, executing the step (2); otherwise, executing the step (3).
(2) And obtaining a primitive list of the current component type of the current layer to determine BIM model primitives.
(3) And acquiring the selected arrangement range.
Specifically, the determination of BIM model primitives is divided into two operational scenarios: firstly, when a user does not select an arrangement range, BIM model primitives are all primitives of the current component type of the current layer, namely, only the arrangement diagram information of the primitives is displayed; secondly, when a user selects an arrangement range, only the information of the arrangement diagram of the primitives in the arrangement range is displayed when the user enters the arrangement diagram.
When the arrangement range is not selected, only the primitives in the primitive list of the current component type of the current layer are used as BIM model primitives, instead of carrying out steel bar arrangement on all the primitives, the data processing amount of steel bar arrangement is reduced, and the problem of operation blocking under the condition of large area can be avoided.
S222, converting the three-dimensional steel bar lines of the BIM model primitives into two-dimensional arrangement diagram data based on the three-dimensional steel bar models so as to generate a steel bar arrangement diagram and determine association relations.
For the generation of the reinforcement bar layout, in this embodiment, the association relationship is calculated by adopting a coordinate transformation method, that is, a transformation matrix from a three-dimensional model to two dimensions is used to transform the reinforcement bar three-dimensional line into two-dimensional layout data.
Further, a conversion matrix for converting the two-dimensional arrangement data into the three-dimensional model of the reinforcing steel bar can be reversely calculated according to the generation process, so that the two-dimensional arrangement diagram data can be converted into the three-dimensional model of the reinforcing steel bar through the conversion matrix after the arrangement diagram is edited.
In some optional implementations of this embodiment, the step S222 may include:
(1) And determining the steel bar information of each steel bar three-dimensional line in the BIM model graphic element by using the steel bar three-dimensional model.
The reinforcement information of the reinforcement three-dimensional line can be obtained from the reinforcement three-dimensional model, and the reinforcement information can comprise the initial end coordinates, the bending length and the like of each reinforcement three-dimensional line.
(2) And determining starting point coordinates and rotation angles of the three-dimensional lines of the steel bars after the three-dimensional lines of the steel bars are converted into two dimensions based on the steel bar information.
The electronic equipment determines the starting point coordinates and the rotation angles of the three-dimensional lines of the steel bars after being converted into two dimensions, so that the corresponding conversion matrix is obtained by utilizing the translation and rotation of the coordinates.
As an alternative implementation manner of this embodiment, step (2) of S222 may include:
2.1 Deducting the bending length from the initial end to obtain the bent steel bar section.
When the three-dimensional model of the steel bar is generated, the bending lengths of the starting end and the tail end of each three-dimensional line of the steel bar are calculated, and the starting end and the bending lengths are recorded in the three-dimensional model of the steel bar at the moment, so that the electronic equipment can acquire the starting end and the bending lengths. When the layout diagram is generated, the bending length is deducted by the starting end, and the bent steel bar section can be obtained.
2.2 Based on the coordinates of the bent steel bar segments, the starting point coordinates of the steel bar three-dimensional line converted into two dimensions are obtained.
And subtracting the starting point of the three-dimensional line of the steel bar after the bending length from the starting end of the three-dimensional line of the steel bar, namely obtaining the values of the corresponding coordinate points x, y and z. The starting point position of the steel bar after three-dimensional conversion into two dimensions can be determined, and the three-dimensional coordinate position can be marked as (x, y, z).
2.3 The rotation angle is determined by utilizing the included angle between the projection of the bent steel bar section and the coordinate axis.
The electronic equipment can calculate the three-dimensional deduction of the bent steel bar segments of the steel bar according to the initial bending length of the steel bar, the initial segments of the deduction of the bent steel bar segments are projected in a overlooking mode, the initial segment two-dimensional line can be obtained, and the included angle between the initial segment two-dimensional line and the X axis is the rotation angle and is marked as a. Wherein the rotation angle is expressed in radians.
And when the starting point coordinates of the three-dimensional line of the steel bar are calculated and converted into two dimensions, deducting the bending length of the three-dimensional line of the steel bar so as to ensure the accuracy of the starting point coordinates and the rotation angle.
(3) The adjustment angle is determined using the range of rotation angles.
And comparing the rotation angle with a preset value, and determining a corresponding adjustment angle theta. For example, if a is greater than or equal to 3 pi/4 and less than 7 pi/4, θ is pi/2, otherwise θ is-pi/2.
(4) And determining a conversion matrix based on the starting point coordinates, the rotation angle and the adjustment angle to determine the association relation, wherein the conversion matrix comprises a first conversion matrix from three dimensions to two dimensions and a second conversion matrix from two dimensions to three dimensions. The association relation is represented by the first conversion matrix and the second conversion matrix.
Specifically, the three-dimensional to two-dimensional first transformation matrix can be calculated by the following formula:
the two-dimensional to three-dimensional second transformation matrix can be calculated by the following formula:
further, when the reinforcement wire is in the XOY plane, the three-dimensional to two-dimensional first transformation matrix may be expressed as:
the second transformation matrix from two dimensions to three dimensions can be expressed as:
whether the reinforcement line is in the XOY plane is determined by the type of reinforcement, for example, the side reinforcement of the plate and the horizontal reinforcement of the wall are all in the XOY plane.
(5) And generating a reinforcement bar layout diagram by using the conversion matrix.
And determining a conversion matrix by utilizing the reinforcement information of each reinforcement three-dimensional line in the BIM model graphic element, and realizing a first conversion matrix from three-dimensional to two-dimensional and a second conversion matrix from two-dimensional to three-dimensional, so that the two-dimensional arrangement diagram can be converted into a three-dimensional reinforcement three-dimensional model through the second conversion matrix after the arrangement diagram is edited, and the arrangement efficiency of the reinforcement is improved.
In some optional implementations of this embodiment, when the electronic device generates the reinforcement bar layout plan using the reinforcement bar three-dimensional model, the electronic device may also generate a reinforcement bar contour line, so as to be used for primarily defining the reinforcement bar in the subsequent construction process, or facilitate a subsequent confirmation of whether each reinforcement bar line meets a construction requirement, or the like.
Specifically, contour lines of the component model (top-view contour lines of walls, beams, plates, etc., top or bottom contour lines of rafts, catchments) reinforcing bar lines, reinforcing bar size information, lap joint information may be displayed. When the layout data is generated through the three-dimensional model, the contour lines of the wall, the beam, the plate and the like are directly realized by adopting the overlooking projection polygons of the model; the bottom surface or the top surface contour line of the water pit and the raft plate is realized by adopting a blanking line algorithm, the top surface contour line is realized by adopting a mode of observing from the positive direction to the negative direction of the Z axis, and the bottom surface contour line is realized by adopting a mode of observing from the negative direction to the positive direction of the Z axis. The above manner of generating the contour lines of the respective members is merely an example, and the scope of the present invention is not limited thereto, and may be adjusted accordingly according to actual needs.

According to the reinforcement bar arrangement method provided by the embodiment, BIM model graphic elements needing to be arranged are obtained before the reinforcement bar arrangement is generated, instead of generating the reinforcement bar arrangement for all graphic elements, namely, the arrangement method can be used for creating the arrangement according to the range so as to solve the problem of operation blocking under the condition of large area.
In this embodiment, a method for arranging reinforcing bars is provided, which may be used in electronic devices, such as computers, mobile phones, tablet computers, etc., fig. 5 is a flowchart of a method for arranging reinforcing bars according to an embodiment of the present invention, as shown in fig. 5, where the flowchart includes the following steps:
s31, obtaining a three-dimensional model of the steel bar.
Please refer to the embodiment S21 shown in fig. 2 in detail, which is not described herein.
S32, generating a steel bar arrangement diagram based on the steel bar three-dimensional model and determining the association relation between the steel bar three-dimensional model and the steel bar arrangement diagram.
Please refer to the embodiment S22 shown in fig. 2 in detail, which is not described herein.
S33, modification of the reinforcement bar layout diagram is obtained.
Please refer to the embodiment S23 shown in fig. 2 in detail, which is not described herein.
And S34, adjusting the three-dimensional model of the steel bar based on the association relation and the modification.
The association relation comprises a second conversion matrix from two dimensions to three dimensions. Specifically, the step S34 may include:
s341, obtaining the coordinates of each reinforcement wire in the modified reinforcement bar layout.
As described above, if the electronic device adjusts the arrangement of the individual reinforcement wires in the reinforcement bar arrangement chart, the electronic device may obtain the coordinates of the modified individual reinforcement wires.
And S342, adjusting the three-dimensional model of the steel bar based on the coordinates of each steel bar line and the two-dimensional to three-dimensional second conversion matrix.
After the coordinates of each modified reinforcing steel bar line are obtained, the electronic equipment can correspondingly adjust the reinforcing steel bar three-dimensional model by utilizing a two-dimensional to three-dimensional second conversion matrix. For the second conversion matrix from two dimensions to three dimensions, please refer to the related description in the embodiment shown in fig. 2 in detail, and the detailed description is omitted herein.
S343, displaying the adjusted reinforcement bar layout.
After the electronic device generates the rebar placement layout, the rebar placement layout may be displayed on an interface; alternatively, the adjusted rebar placement pattern or the like may be displayed. When the steel bar arrangement diagram is displayed, the graphic elements can be displayed in batches.
According to the reinforcement bar arrangement method provided by the embodiment, the modified reinforcement bar arrangement diagram is mapped into the reinforcement bar three-dimensional model by using the second conversion matrix, so that synchronous modification of the reinforcement bar three-dimensional model is realized, and the modified reinforcement bar arrangement diagram is displayed, so that the reinforcement bar arrangement diagram is edited again.
In some optional implementations of this embodiment, the step S343 may include:
(1) And obtaining the graphic elements displayed in batches in the steel bar arrangement diagram.
The graphic elements displayed in batch can be selected by a user, customized by electronic equipment, and the like, and the graphic elements are not limited at all, and the electronic equipment can be ensured to acquire the graphic elements required to be displayed in batch.
(2) And processing the primitives displayed in batches to display in batches.
After the primitives for the batch display are acquired, they may be combined, or the layout diagram at a certain viewing angle or at certain viewing angles may be displayed, so as to display the primitives for the batch display.
The primitives are displayed in batches in the same layout, and each primitive does not need to be displayed separately, so that the modification efficiency is improved.
The conventional column and wall layout schemes are generally single walls or multiple layers of columns are displayed together, so that the problems caused by the scheme are low inspection and modification efficiency, the layout is mostly vertical layout information, and plane positioning information is lacked. In this embodiment, a batch layout display mode and a single multi-layer display mode are provided for column primitives; aiming at the wall primitives, the invention constructs the wall layout in a batch display mode.
When the primitives displayed in batch are column primitives, step (2) of S343 may include:
2.1 Classifying the column primitives using attribute information of each column primitive.
The electronic equipment classifies the columns according to the basic bottom, basic thickness, basic top/layer bottom, the net height of the layer, beam height, upper net height and the like according to the primitive range selected by the user, and the columns with the same information are classified into one type.
2.2 For the column primitives with the same classification, when the three-dimensional lines of the reinforcing steel bars of the column primitives are consistent with other data except for positioning points, the column primitives with the same classification are combined and displayed, and the combined sources are recorded.
And if the data of the three-dimensional lines of the steel bars except the positioning points are consistent, merging the column graphic elements of the same classification into a steel bar to be displayed in a layout diagram, recording merging sources, and synchronizing the three-dimensional models of the steel bars according to the merging sources during modification.
And a batch capture map display mode and a single multi-layer display mode are provided for the column, so that batch modification of column primitives can be ensured.
The existing display for the wall layout is a single component layout, which is essentially different from the present solution. The present solution eliminates the display of a single layout, but displays a wall layout at least one viewing angle. Specifically, when the primitives displayed in batch are wall primitives, step (2) of S343 may include:
2.1 A row pattern of each wall primitive at least one viewing angle is obtained.
2.2 Based on a layout at least one viewing angle).
The method comprises the steps of displaying a steel bar arrangement diagram according to a wall overlooking position by default, arranging horizontal steel bars on the left side and the right side of a wall contour line according to elevation sequences and arrangement numbers, arranging the first row on the left side, arranging the other rows on the right side according to sequences, displaying vertical steel bars in the wall contour line in a top view by using coils, adding capping, communicating and dowel bar marks to mark the construction scheme, and displaying blanking information of the vertical steel bars by using a centralized marking table. Under the condition that the vertical rib structure of the wall is complex, the side view drawing function can be used for drawing the side view information of the vertical rib of a certain wall, so that the vertical rib can be conveniently inspected and modified.
The wall layout is constructed in a batch display mode aiming at the wall primitives, namely, the layout of the wall primitives under at least one view angle is displayed in batch, positioning information is provided, and the modification efficiency is high.
Because the steel bars are often lifted by hands, the steel bars are often rusted on the hands after the steel bars are lifted, the layout diagram is frequently dirty locally, and the length data of the local steel bars can not be seen. If the display of the overlong steel bars is concentrated on the left side, the first view is more concentrated and convenient, the second view can prevent the pollution to the position with data on the left side as much as possible, and the position with data is more fixed. Often have the construction evening, connect the data of overlength reinforcing bar and concentrate on the left side, under the not good circumstances of light evening, look over the advantage that the map data has more obvious. Based on this, in other optional implementation manners of this embodiment, S343 may include:
(1) And obtaining the short operation of the blanking length.
(2) And sequentially arranging the information of the reinforcing steel bars at the end positions of each reinforcing steel bar line in the reinforcing steel bar arrangement diagram.
When the user selects the shorthand of the blanking length, the shorthand of the steel bar information is regenerated at the initial position of the steel bar line according to a certain sequence, and the original scattered steel bar information is hidden. When the short choice of the blanking length is removed, the blanking length is shortened and hidden, the original steel bar information is displayed, and the short choice is only for intensively displaying the scattered steel bar blanking information in the existing scheme. The arrangement sequence of the steel bar information can sequentially comprise the sequence of the number of the steel bars, the blanking length and the lap joint type.
For example, see fig. 6a before shorthand, and fig. 6b for a post shorthand effect.
Providing information of the arrangement diagram for arranging the steel bar lines, namely providing a scheme for labeling and abbreviated arrangement diagram steel bars, and optimizing the information display effect of the arrangement diagram. The simple and written scheme of the steel bar label enables the label information to be more concise and clear, and is convenient for field viewing.
