In one embodiment, as shown in fig. 2, a method for obtaining a target reinforcing bar is provided, which is described by taking the method as an example of being applied to the terminal in fig. 1, and includes the following steps:
s202: and receiving a target wall body selection instruction in the building information model, and determining a target wall body based on the target wall body selection instruction.
Specifically, the building information model refers to a BIM model in which various building elements of a building and their combination, such as walls, doors and windows, etc., are displayed.
The target wall is a wall in the building information model, wherein in this embodiment, the target wall is a wall that needs to be reinforced on the wall, for example, a hole exists in the target wall, and therefore, the target wall needs to be reinforced by the reinforcing steel bars, so that it is necessary to determine the target wall first to calculate the reinforcing steel bars.
Specifically, referring to fig. 3 to 5, fig. 3 is a schematic diagram of a target wall in an embodiment, fig. 4 is a schematic diagram of a hole in the target wall shown in fig. 3, and fig. 5 is a detailed schematic diagram of the target wall shown in fig. 3, where as shown in fig. 3, a terminal receives a target wall selection instruction in a building information model, so as to select a target wall, that is, a portion inside a rectangular frame in fig. 3, and specifically referring to fig. 4, where the selected portion inside the rectangular frame is a wall, and a hole is formed in the wall, which needs to be wall-reinforced, and as shown in fig. 5, details of the hole are enlarged.
S204: a set of rebars that pass through the target wall is extracted from the building information model.
Specifically, the set of rebars passing through the target wall is specifically a set of rebars passing through an opening in the target wall, and specifically, the terminal may obtain the set of rebars passing through the target wall according to the position information of the target wall in the building information model, that is, coordinates of each surface of the opening.
For example, the terminal may obtain a range of coordinates of the target wall, and then extract the rebars in the building information model that intersect the range of coordinates.
Specifically, referring to fig. 6 and 7, fig. 6 is a set of rebars through the target wall shown in fig. 3, and fig. 7 is a simplified diagram of a set of rebars through the target wall shown in fig. 3.
S206: and reading a steel bar positioning line in the steel bar set.
Specifically, the steel bar positioning line is a representation line of each steel bar, which may be a median line of the steel bar, and the like, and is not particularly limited herein.
S208: and obtaining the steel bar corresponding to the steel bar positioning line with the minimum distance with the target wall body as the target steel bar.
Specifically, after the target wall and the steel bar positioning lines are determined, the terminal may traverse each steel bar positioning line to obtain a distance between the steel bar positioning line and the target wall, and then select the steel bar corresponding to the steel bar positioning line with the smallest distance as the target steel bar. The distance calculation can be converted into the distance from a point to a surface, so that the calculation is simplified. Specifically, referring to fig. 8, fig. 8 is a schematic diagram of a target rebar corresponding to the target wall shown in fig. 3.
According to the target reinforcing steel bar obtaining method, through the building information model, after the target wall body is selected, the reinforcing steel bar set penetrating through the target wall body is automatically read, so that the reinforcing steel bars closest to the target wall body are automatically calculated according to the reinforcing steel bar positioning lines in the reinforcing steel bar set, a user does not need to calculate the reinforcing steel bars by himself, time is saved, and the efficiency of development and design is greatly improved.
In one embodiment, acquiring the rebar corresponding to the rebar positioning line with the smallest distance to the target wall as the target rebar includes: determining a target plane of a target wall; and (4) transmitting the target plane and the steel bar positioning line into a pre-packaged target steel bar calculation function model, and calculating to obtain the target steel bar.
In particular, the target plane may comprise at least one, for example, a vertical plane and a horizontal plane of the target wall, i.e., two connected out-side or in-side four sides of the target wall, one being a vertical plane and one being a horizontal plane.
Specifically, the function of extracting the target steel bar may be made into a library file in advance, so that the library file is introduced into the project, that is, the encapsulated function model corresponding to the library file may be called to perform calculation when needed.
In this embodiment, in order to avoid the repeatability of programming, the library file is encapsulated in advance to obtain a target steel bar calculation function model, so that when a target steel bar needs to be calculated each time, input parameters of the model, that is, a target wall and a steel bar positioning line are determined, a distance from the steel bar positioning line to the target wall (that is, a target plane) can be compared, and the steel bar positioning line with the minimum distance is returned.
In the embodiment, the library file is packaged in advance to obtain the target steel bar calculation function model, and only the corresponding target steel bar calculation function model needs to be called during calculation, so that the repeatability of programming is avoided.
In one embodiment, the method for obtaining a target steel bar by calculation by transferring a target plane and a steel bar positioning line into a pre-packaged target steel bar calculation function model includes: calculating a unit normal vector of a target plane through a pre-packaged target steel bar calculation function model; randomly selecting a reference point from the target plane; respectively selecting target points from each steel bar positioning line; calculating the distance from the steel bar positioning line to the target wall according to the reference point, the target point and the unit normal vector; and selecting the steel bar corresponding to the steel bar positioning line with the minimum distance as the target steel bar.
Specifically, referring to fig. 9 to 11, fig. 9 is a schematic diagram of an embodiment where a target point is on a target plane, fig. 10 is a schematic diagram of an embodiment where a target point is on a target plane, and fig. 11 is a schematic diagram of an embodiment where a target point is under a target plane.
Specifically, for convenience, wherein the reference point is represented by planeP, the target point is represented by point, the plane normal vector is represented by planeNormal, and the unit normal vector is represented by normal.
The unit normal vector is the direction quantity of the target plane, the terminal calculates the plane normal vector first, and then the unit normal vector of the target plane can be obtained through normalization. The reference point is any point in the target plane, the target point is a point on each steel bar positioning line, and the terminal calculates the distance from the steel bar positioning line to the target wall by calculating the distance from the target point to the target plane.
Optionally, the terminal calculates a distance from the steel bar positioning line to the target wall according to the reference point, the target point and the unit normal vector, and includes: calculating to obtain a first distance according to the reference point and the unit normal vector; calculating to obtain a second distance according to the target point and the unit normal vector; and calculating the distance from the steel bar positioning line to the target wall according to the second distance and the first distance.
For example, in practical application, the terminal calculates the dot product of the unit normal vector normal and the reference point planeP, and inverts the result to be denoted as d. And then calculating the dot product of the unit normal vector normal and the point of the target point, and adding the result d to obtain the distance from the target point to the target plane.
Referring to fig. 9 to 11, since the target point is on the target plane in fig. 9, the dot product of the unit normal vector normal and the reference point plan and the dot product of the unit normal vector normal and the target point are equal, and thus the calculated distance is 0. In fig. 10, the target point is above the target plane, and therefore the sum of the dot product of the normal vector normal and the target point and the dot product of the normal vector normal and the reference point planeP is positive. As in fig. 11, the target point is below the target plane, so the sum of the dot product of the unit normal vector normal and the target point and the dot product of the unit normal vector normal and the reference point planeP is negative.
In the above embodiment, a detailed principle of the target steel bar calculation function model is given, and after the terminal acquires the steel bar positioning lines and the target plane, the terminal can directly call the target steel bar calculation function model to calculate and obtain the distance from each steel bar positioning line to the target wall.
In one embodiment, extracting the set of rebars from the building information model through the target wall comprises: extracting a rebar set passing through a vertical plane of the target wall and a rebar set passing through a horizontal plane of the target wall from the building information model; determining a target plane of a target wall, comprising: and determining a horizontal plane and a vertical plane of the target wall body, wherein the target plane corresponding to the rebar set penetrating through the vertical plane of the target wall body is the horizontal plane, and the target plane corresponding to the rebar set penetrating through the horizontal plane of the target wall body is the vertical plane.
Specifically, as shown in fig. 7, the rebar penetrating through the target wall includes horizontal and vertical rebars, so that when the terminal calculates the rebar set, the terminal may first determine a horizontal plane and a vertical plane in the target wall, then determine ranges of the horizontal plane and the vertical plane respectively, and further obtain horizontal and vertical coordinate ranges, thereby determining the rebar set penetrating through the horizontal plane according to the horizontal coordinate range, and similarly obtain the rebar set penetrating through the vertical plane. All the positioning lines of the four face steel bars passing through the opening are determined as shown in fig. 7, namely the steel bars passing through the opening transversely and vertically and the steel bars passing through the opening vertically.
Then, the steel bar positioning lines closest to the horizontal plane and the treatment plane are respectively obtained, that is, calculation is performed according to the target steel bar calculation function model to obtain two positioning lines closest to the outer wall surface, which can be specifically combined with fig. 8.
In the above embodiment, since the opening has a plurality of faces, the number of the target rebars to be determined needs to be determined according to the number of the faces of the opening, and then the target rebar calculation function model is called to perform calculation.
In one embodiment, after obtaining the rebar corresponding to the rebar positioning line with the smallest distance to the target wall as the target rebar, the method further includes: acquiring a deviation rule of a steel bar positioning line corresponding to the determined target steel bar; and generating a reinforcing steel bar in the building information model according to the offset rule.
Specifically, the reinforcing bar is generated based on the deviation of two positioning lines by a prescribed distance. The reinforcing steel bar arrangement rule comprises: if meet horizontal reinforcing bar, the reinforcing bar central line of above-mentioned one arranged is the starting point, and the interval that 4 times of reinforcement reinforcing bar diameter d is rearranged, the reinforcing bar of vertical direction is the same as reason.
In the embodiment, through the building information model, after the target wall is selected, the reinforcing steel bar set penetrating through the target wall is automatically read, so that the reinforcing steel bars closest to the target wall are automatically calculated according to the reinforcing steel bar positioning lines in the reinforcing steel bar set, the calculation by a user is not needed, the time is saved, the reinforcing steel bars can be quickly calculated according to the target reinforcing steel bars, and the efficiency of development and design is greatly improved.
In one embodiment, as shown in fig. 12, a method for obtaining a target reinforcing bar is provided, which is described by taking the method as an example of being applied to the terminal in fig. 1, and includes the following steps:
s1202: and selecting a target wall in the building information model.
Specifically, the method for selecting the target wall may be as described above, and is not described herein again.
S1204: and calling a preset functional interface to enable the functional interface to process the target wall according to the method in any one of the embodiments to obtain the target steel bar.
Specifically, the obtaining method of the target reinforcing steel bar may refer to the above, which is not described herein again, and after the target reinforcing steel bar is obtained through calculation, the terminal may obtain the reinforcing steel bar through calculation according to the target reinforcing steel bar, and the calculating method may also refer to the above.
In the embodiment, through the building information model, after the target wall is selected, the reinforcing steel bar set penetrating through the target wall is automatically read, so that the reinforcing steel bars closest to the target wall are automatically calculated according to the reinforcing steel bar positioning lines in the reinforcing steel bar set, the calculation by a user is not needed, the time is saved, the reinforcing steel bars can be quickly calculated according to the target reinforcing steel bars, and the efficiency of development and design is greatly improved.
Specifically, with reference to fig. 3 to 11, the wall reinforcement function is taken as a scene in which the reinforcement bar closest to the inner and outer wall surfaces needs to be taken to prepare for the subsequent calculation of the position of the reinforcement bar.
As shown in fig. 3, a set of reinforcing bars passing through the vertical plane of the opening is obtained first, and then the reinforcing bar with the shortest distance to the outer side of the wall surface among the transverse reinforcing bars is obtained to prepare for placing the reinforcing bar subsequently. Firstly, selecting a wall with an opening, acquiring a reinforcement set of which the opening passes through a vertical plane and a reinforcement set of which the opening passes through a horizontal plane, determining all positioning lines of four surface reinforcements passing through the opening, namely reinforcements passing through the opening transversely and vertically and reinforcements passing through the opening vertically (figure 7), and obtaining two positioning lines (figure 8) which are closest to the outer wall surface based on an algorithm; and then generating a reinforcing steel bar based on the deviation of the two positioning lines by a specified distance.
When the target steel bar is calculated, a reference point, a target point and a unit normal vector are determined, so that the distance from the target point to a target plane can be calculated and obtained to serve as the distance from a steel bar positioning line to a target wall. Specifically, a unit normal vector of the plane normal vector is obtained first and is recorded as normal. The dot product of the unit normal vector normal and the reference point planeP is then calculated and the result is inverted and denoted as d. And finally, calculating the dot product of the unit normal vector normal and the point of the target point, and adding the result d to obtain the distance between the point and the plane.
According to the target reinforcing steel bar obtaining method, through the building information model, after the target wall body is selected, the reinforcing steel bar set penetrating through the target wall body is automatically read, so that the reinforcing steel bars closest to the target wall body are automatically calculated according to the reinforcing steel bar positioning lines in the reinforcing steel bar set, a user does not need to calculate the reinforcing steel bars by himself, time is saved, and the efficiency of development and design is greatly improved.
