Therefore, it is troublesome to model one side mold first and then separately model the other side mold in order to install attachments attached to a connection object or other form such as foam tie or the like. In this process, the position information of the attached objects such as the connection objects and the attachments, which are modeled in this process, is often inconsistent with the modeled panel. If such a design error is found, the entire time must be remodeled, have. In addition, there is no information about the thickness of the member, so that it is inconvenient to manually input the specification of the connection object such as form tie or the setting of the notch position.

In addition, since the existing model is modeled by filling a form on the 2D face of the member, it is difficult to completely re-model the form panel of the member face when the 2D shape information is changed due to the design change.

In order to solve the above problems, the present invention provides a form panel automatic modeling method capable of shortening a work time by minimizing information processing amount for designing a form panel by matching and modeling a form by member sectional information extracted from 3D form information .

The present invention provides a method for automatically modeling a formwork panel which can easily match an attached object such as a form tie or the like attached to other formworks and minimizes a design error.

The present invention is for automatically designing a form panel such as an aluminum foam or a steel foam, and is applicable to a wall, a column, and a beam where a form panel is installed on both sides of a member.

The present invention minimizes the amount of information to be processed by minimizing the amount of information to be processed, minimizing design errors, and facilitating attachment matching by modeling and modeling the form using the member section information extracted from the 3D shape information of each member constituting the structure A method for automatically modeling a form panel is provided.

According to the present invention, it is possible to easily modify the related information even when the design is changed, so that the design of the form panel is easy.

In the step (a), 3D shape information of the structure is generated.

The 3D shape information may be stored as BIM digital data.

Next, (b) section shape information is output from the 3D shape information of each member of the structure.

In the step (b), a member for outputting the cross-sectional shape information is first selected.

Then, the 2D sectional shape information of the member is outputted from the 3D shape information of each member. At this time, the cross-sectional shape information is output for each position where the cross-sectional shape is changed in one member.

The cross sectional shape information is automatically output as geometrical information in two dimensions of the cross section. That is, the height and width of the wall, the width and height of the beam, and the size of the cross section are automatically output by the geometric shape information of the output 2D section.

In addition, the cross-sectional width of the target section is automatically calculated by calculating the interval between the cross-sectional baselines. That is, according to the distance between the sectioned section and the section, the wall length in case of wall, beam length in case of beam, and column height information in case of column are automatically output.

Thereafter, step (c) is performed in which the form panel is modeled by the outputted sectional shape information and the form matching information is generated.

In the step (c), the form panel is matched to the outer surface of the member section using the sectional shape information output in the step (b).

For example, in the case of a wall, the form panel is matched by the height and width information of the wall in the cross-sectional shape information.

As a result, the calculation for the form panel modeling becomes very simple, and the automatic design program processing speed becomes very fast.

Finally, (d) the die matching information is output.

In the step (d), the form panel information for each cross section matched in the step (c) may be outputted in the form of a table according to the user and confirmed. Wherein the output includes being displayed on the user terminal.

In the step (d), the form matching information may include the quantity information of each form panel type.

Accordingly, the form panels can be grouped by type, and the required form quantities of each type can be calculated, thereby providing the related form panel production information.

FIG. 2 is a diagram showing a member information management window among the 2D cross-sectional shape information output from the 3D shape information.

In the step (b), the output section shape information may be changed by a user.

The member information management window of the 2D cross-sectional shape information outputted from the 3D shape information of each member of the structure is shown in Fig.

2, the information output from the 3D shape information is set as a default value, and each data value can be configured to be changed by the user.

That is, since the form panel modeling data is matched to the sectional shape information, the change can be easily reflected in the automatic design of the form panel by merely changing the information of the member information management window at the time of design change.

FIG. 3 is a view showing a 2D view for outputting the form matching information, FIG. 4 is a view showing a 3D view for outputting the form matching information, FIG. 5 is a view showing the form matching information output from the 2D view or the 3D view, FIG.

In the step (d), the form matching information is linked to the 3D shape information and output from the 3D shape information.

The form matching information can be linked to the 3D shape information so that the user can output and confirm it according to the use.

Accordingly, the user can select and output the desired member and part from the 3D shape information.

At this time, a 2D viewer as shown in FIG. 3 or a 3D viewer as shown in FIG. 4 selects a desired position in the 3D shape information, and the form matching information is output as shown in FIG.

Since the die matching information is linked to the 3D shape information as well as the sectional shape information, the die matching information can be output in a state in which the die matching information is arranged on the member surface.

6, in step (c), the form panel information matched by the cross-sectional type is automatically matched to the target cross-section information corresponding to the type of the design target cross-section from the matching DB set in advance, . ≪ / RTI >

Here, the process of generating the die matching information will be described. In the matching DB in which die form panel information matched for each cross-sectional type is stored in advance, the cross-sectional type to which the target cross-section belongs is searched. Then, the form panel matching information is automatically generated by matching the form panel information corresponding to the form panel information.

The matching DB may be data included in a central server and commonly used for a plurality of projects.

If the cross-sectional type matching the target cross-section is not searched in the matching DB, the user can manually match the new form panel information to the target cross-section, and store the newly matched cross-form panel information in the matching DB.

As the number of executed projects increases, various cross-sectional type information is stored in the matching DB, thereby improving the automation design efficiency of the form panel.

In the step (c), connection object installation information for connecting the form panels facing each other according to the section type is preset in the matching DB, and the connection object is automatically matched with the form panel information matching the design object section .

The wall, column, and beam members are installed on both sides of the member so that the form panels face each other. At this time, the facing dice panels are connected to each other by a connection object such as a form tie.

The connection object installation information such as the installation location and the number of such connection objects is determined by the member cross-sectional shape. Therefore, it is possible to match and allocate the connection object installation information for each cross-sectional type to the matching DB in which the information for each cross-sectional type is stored.

Thus, connection object modeling can be performed automatically.

In addition, by modeling the connection object installation information directly to match the form panels on both sides of each member, the inconsistency of the connection object installation position does not occur.

In the step (c), the material specification of the connection object may be automatically determined according to the member width information included in the cross-sectional shape information of the cross-section of the design object.

The 2D sectional shape information output in the step (b) already includes the thickness information of the member. Accordingly, in step (c), the material specification such as the length, the kind, and the notch position of the connection object can be automatically determined and stored in the die matching information without any setting.

FIG. 7 is a view showing an attachment information management window of 2D sectional shape information output from 3D shape information. FIG.

In the step (c), the attachment DB attachment information to be attached to the form according to the cross-sectional type is preset in the matching DB, so that the attachment information can be automatically matched together with the form panel information matched to the cross- .

FIG. 7 shows an attachment information management window of the 2D sectional shape information output from the 3D shape information.

The cross-sectional shape information grouped by type includes various information such as the position and size of the window, the size of the opening, the number of corners, and the like. In general, the attachment attached to the form panel is determined by the cross-sectional information as described above.

Therefore, the attachment modeling can be automatically performed by preliminarily pre-matching and allocating attachment attachment information for each cross-sectional type to the matching DB.

The data of the attachment information management window is set to a default value by calling preset data in the matching DB, but it is also possible for the user to manually change the installation position or the like.

Similarly, the connection object information described above can be manually changed by the user.
