In this embodiment, a reinforcing bar arranging method is provided, which can be used in electronic devices, such as computers, mobile phones, tablet computers, and the like, fig. 1 is a flowchart of a reinforcing bar arranging method according to an embodiment of the present invention, and as shown in fig. 1, the flowchart includes the following steps:
and S11, acquiring a three-dimensional model of the steel bar.
The steel bar three-dimensional model can be obtained by the electronic equipment from the outside or calculated by the electronic equipment by utilizing a construction BIM model. Specifically, the electronic device can automatically calculate and generate the steel bar three-dimensional model according to the construction BIM model and the leveling information by adding steel bar leveling information to the construction BIM model. Of course, the manner of generating the three-dimensional model of the steel bar is not limited to the above, and other manners may be used.
The construction BIM model can be obtained by manually modeling on electronic equipment by a user, can also be obtained by identifying and modeling through CAD (computer-aided design) by the electronic equipment, or can also be obtained by importing a GTJ (building integrity) model into the electronic equipment, and the like. The method for acquiring the construction BIM model by the electronic equipment is not limited at all, and the corresponding setting can be specifically carried out according to actual requirements.
And S12, generating a steel bar arrangement pattern based on the steel bar three-dimensional model and determining the association relationship between the steel bar three-dimensional model and the steel bar arrangement pattern.
The reinforcing steel bar layout pattern is a two-dimensional data line of the reinforcing steel bars, and each reinforcing steel bar line is represented in a reinforcing steel bar three-dimensional line mode in the reinforcing steel bar three-dimensional model, so that the reinforcing steel bar three-dimensional line needs to be mapped into the two-dimensional data line, and the incidence relation between the reinforcing steel bar three-dimensional model and the reinforcing steel bar layout pattern is determined so as to generate the reinforcing steel bar layout pattern. Accordingly, the electronic device may generate the bar layout pattern by using the coordinate conversion method, may also generate the bar layout pattern by using the projection method, or may also generate the bar layout pattern by using other methods. The method is not limited at all, and only the electronic equipment is ensured to generate the steel bar arrangement diagram based on the steel bar three-dimensional model, namely, the incidence relation between the steel bar three-dimensional model and the steel bar arrangement diagram is established.
Details about this step will be described later.
And S13, acquiring the modification of the steel bar layout.
After the electronic equipment generates the reinforcing steel bar layout plan, a user modification interface is provided, the user modifies the reinforcing steel bar layout plan on the interface, and accordingly the electronic equipment can obtain the modification of the reinforcing steel bar layout plan.
The modification may be modification of the information of the reinforcing steel bars, modification of the arrangement of the reinforcing steel bars, and the like, and may specifically be corresponding modification according to actual requirements, without particularly referring to a certain modification.
And S14, adjusting the three-dimensional model of the steel bar based on the association relation and the modification.
As described above, the bar layout is generated based on the three-dimensional model of the bars, and there is a relationship between the two. When the arrangement layout of the steel bars is modified, the three-dimensional model of the steel bars can be automatically adjusted correspondingly, so that the linkage adjustment of the three-dimensional model of the steel bars is realized.
For example, when the bar layout is generated by coordinate transformation, the electronic device may adjust the three-dimensional model of the bars by using the inverse coordinate transformation and by using the modification of the bar layout.
According to the reinforcing steel bar arrangement method, the reinforcing steel bar arrangement pattern is generated based on the reinforcing steel bar three-dimensional model, an incidence relation exists between the reinforcing steel bar arrangement pattern and the reinforcing steel bar three-dimensional model, the reinforcing steel bar three-dimensional model can be synchronously adjusted when the reinforcing steel bar arrangement pattern is modified, and the reinforcing steel bar arrangement efficiency is improved.
In this embodiment, a reinforcing bar arranging method is provided, which can be used in electronic devices, such as computers, mobile phones, tablet computers, and the like, fig. 2 is a flowchart of a reinforcing bar arranging method according to an embodiment of the present invention, and as shown in fig. 2, the flowchart includes the following steps:
and S21, acquiring a three-dimensional model of the steel bar.
As shown in fig. 3, a new project is built in the electronic device to obtain a construction BIM model. For example, manual modeling, CAD recognition modeling, or import GTJ models, etc. may be employed.
After the electronic equipment obtains the construction BIM model, the electronic equipment adds the information of the steel bar leveling method to the construction BIM model and then carries out summary calculation to obtain the steel bar three-dimensional model.
For the rest, please refer to S11 in the embodiment shown in fig. 1, which is not described herein again.
And S22, generating a steel bar arrangement pattern based on the steel bar three-dimensional model and determining the association relationship between the steel bar three-dimensional model and the steel bar arrangement pattern.
Specifically, the above S22 may include:
s221, acquiring the BIM model primitive.
The electronic equipment acquires a BIM model, wherein the three-dimensional model of the steel bar is attached to the graphic primitives of the BIM model. That is, after acquiring the BIM model, the electronic device may provide a selection of the BIM model primitive. Specifically, the user may select a box in the BIM model, or click, etc. Accordingly, the electronic device can acquire the BIM model primitive.
Or, the electronic device may also 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 manners.
In some optional implementations of this embodiment, as shown in fig. 4, the step S221 may include:
(1) judging whether an arrangement range is selected;
when the arrangement range is not selected, executing the step (2); otherwise, executing step (3).
(2) And acquiring a primitive list of the current component type of the current layer to determine the BIM model primitive.
(3) And acquiring the selected arrangement range.
Specifically, the determination of the BIM model primitive is divided into two operation scenarios: firstly, when a user does not select an arrangement range, the BIM model primitives are all the primitives of the current component type of the current layer, namely, only the arrangement layout information of the part of primitives is displayed; and secondly, when the user selects the arrangement range, only displaying the arrangement layout information of the primitives in the arrangement range when entering the arrangement layout.
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 the BIM model primitives, instead of arranging all the primitives with reinforcing steel bars, so that the data processing amount of reinforcing steel bar arrangement is reduced, and the problem of operation blockage under the condition of large area can be avoided.
S222, converting the steel bar three-dimensional lines of the BIM model primitives into two-dimensional layout data based on the steel bar three-dimensional model so as to generate a steel bar layout and determine the association relationship.
For the generation of the steel bar arrangement diagram, in this embodiment, the association relationship is calculated by using a coordinate transformation method, that is, a transformation matrix from a three-dimensional model to a two-dimensional model is used to transform the three-dimensional lines of the steel bars into two-dimensional arrangement diagram data.
Furthermore, a conversion matrix for converting the two-dimensional layout data into the three-dimensional model of the steel bars can be reversely calculated according to the generation process, so that the two-dimensional layout data can be converted into the three-dimensional model of the steel bars through the conversion matrix after the layout is edited.
In some optional implementations of this embodiment, the step S222 may include:
(1) and determining the reinforcing steel bar information of each reinforcing steel bar three-dimensional line in the BIM model primitive by using the reinforcing steel bar three-dimensional model.
The reinforcing steel bar information of the reinforcing steel bar three-dimensional lines can be obtained from the reinforcing steel bar three-dimensional model, and the reinforcing steel bar information can comprise the coordinates of the starting end of each reinforcing steel bar three-dimensional line, the bending length and the like.
(2) And determining the starting point coordinates and the rotation angle of each steel bar three-dimensional line after the steel bar three-dimensional line is converted into two dimensions based on the steel bar information.
And the electronic equipment determines the coordinates of the starting point and the rotation angle of each steel bar three-dimensional line after the steel bar three-dimensional line is converted into two dimensions, so that the translation and the rotation of the coordinates are utilized to obtain a corresponding conversion matrix.
As an optional implementation manner of this embodiment, step (2) of the above S222 may include:
and 2.1) deducting the bending length from the starting 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 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 generating the layout pattern, the bent reinforcing steel bar section can be obtained by deducting the bending length by using the starting end.
2.2) obtaining a starting point coordinate after the three-dimensional line of the steel bar is converted into two-dimensional line based on the coordinate of the bent steel bar section.
And deducting the starting point of the three-dimensional line of the reinforcing steel bar after the bending length is taken out from the starting end of the three-dimensional line of the reinforcing steel bar, namely the values of the corresponding coordinate points x, y and z. The position of the starting point of the steel bar after three-dimensional conversion into two-dimensional can be determined, and the three-dimensional coordinate position can be marked as (x, y, z).
And 2.3) determining the rotation angle by utilizing the included angle between the projection of the bent steel bar section and the coordinate axis.
The electronic equipment can calculate a steel bar section with the three-dimensional deducted bend of the steel bar according to the initial bending length of the steel bar, the initial section with the deducted bend of the steel bar section is subjected to overlook projection, an initial section two-dimensional line can be obtained, and the included angle between the initial section two-dimensional line and the X axis is the rotating angle and is marked as a. Wherein the rotation angle is expressed in radians.
When the starting point coordinate of the three-dimensional line of the reinforcing steel bar is converted into the two-dimensional line, the bending length of the three-dimensional line of the reinforcing steel bar is deducted so as to ensure the accuracy of the starting point coordinate and the rotation angle.
(3) And determining the adjusting angle by using the range of the rotating angle.
And comparing the rotation angle with a preset value to determine a corresponding adjustment angle theta. For example, if a is equal to or greater than 3 × π/4 and less than 7 × π/4, θ is π/2, otherwise θ is- π/2.
(4) And determining a conversion matrix based on the coordinates of the starting point, the rotation angle and the adjustment angle so as to determine the incidence 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. Wherein the incidence relation is represented by the first conversion matrix and the second conversion matrix.
Specifically, the first conversion matrix from three dimensions to two dimensions may be calculated by using the following formula:
the second transformation matrix for transforming two-dimension into three-dimension can be calculated by adopting the following formula:
further, when the reinforcement line is in the XOY plane, the first transformation matrix from three dimensions to two dimensions may be expressed as:
the second transformation matrix from two to three dimensions may be represented as:
whether the reinforcement line is on the XOY plane is determined by the type of the reinforcement, for example, the side reinforcement of the slab and the horizontal reinforcement of the wall are on the XOY plane.
(5) And generating a reinforcing bar layout by using the conversion matrix.
The conversion matrix is determined by utilizing the reinforcing steel bar information of each reinforcing steel bar three-dimensional line in the BIM model primitive, the first conversion matrix from three-dimensional to two-dimensional and the second conversion matrix from two-dimensional to three-dimensional are realized, so that the two-dimensional arrangement diagram can be converted into the three-dimensional reinforcing steel bar three-dimensional model through the second conversion matrix after the arrangement diagram is edited, and the reinforcing steel bar arrangement efficiency is improved.
