As illustrated, the 3D design drawing automatic generation device 100 (hereinafter, referred to as an auto generation device) may receive 2D design drawing information as input information.

The two-dimensional design drawing information may include structural general information, which is member list information on the type and shape of a member of a building, drawing structure information on a building structure, and explanatory information on a supply method of reinforcing bars (I) for each situation. Can be.

The member list information may include member type information on types of members such as columns, beams, and slabs, member shape information on shapes for each member type, member structure information on sizes and structures of each member, and the like. .

As such, when the 2D design drawing information is input, the automatic generation apparatus 100 may generate the 3D design drawing information corresponding to the 2D design drawing information by combining the 2D design drawing information.

In other words, the basic structure of the three-dimensional design drawing is generated from the member drawing information including the member list information and the drawing structure information, and the reinforcing bar profile and the building are added by adding reinforcing bar information about the reinforcing bar (I) required for the building. Three-dimensional design drawing information to which the reinforcing bar information, such as the shape, quantity, weight, etc. of the reinforcing bar required to be added can be generated.

Therefore, the automatic generating device 100 does not simply convert the two-dimensional design drawing information into three-dimensional, but obtains the three-dimensional design drawing information including the reinforcing bar structure and the required reinforcing bar information, thereby improving the efficiency of the construction work. Can be further improved.

In the above, the approximate driving method of the automatic generating apparatus 100 was demonstrated. In FIG. 2, the configuration of the automatic generation device 100 will be described.

2 is a block diagram illustrating a configuration of an apparatus 100 for automatically generating a 3D design drawing according to an embodiment of the present invention.

As shown, the automatic generation device 100 includes a memory module 110, a drawing analysis module 120, a rebar analysis module 130, a reinforcement degree analysis module 140, a three-dimensional design module 150, and the like. can do.

The memory module 110 may be a means for receiving and storing two-dimensional design drawing information about a building. If the 2D design drawing information is received from an external terminal through a communication module (not shown), it may be stored. In addition, even when the 2D design drawing information is input through the user input module, it may be stored.

The drawing analysis module 120 may generate member drawing information including the member list information on the member of the building and the drawing structure information on the drawing structure with reference to the 2D design drawing information.

Specifically, the 3D design module 150 generates first 3D design drawing information corresponding to the basic shape of the 3D design drawing information through the member drawing information, and reinforcement degree information and the first 3D design drawing information. The second three-dimensional design drawing information may be generated by including the reinforcing bar information. Accordingly, the finally obtained three-dimensional design drawing information, including the reinforcing bar structure in the three-dimensional shape, and may include all the detailed information, such as the quantity, length, weight, etc. of the reinforcing bar required to create the structure. have.

The configuration of the automatic generating device 100 has been described above. 3 to 6, each step will be described sequentially with respect to a method for automatically generating a 3D design drawing using the design drawing.

3 is a flowchart illustrating a method for automatically generating a 3D design drawing using a 2D design drawing according to another embodiment of the present invention, and FIGS. 4 to 6 are 3 using the 2D design drawing of FIGS. 1 to 3. It is a conceptual diagram for explaining the automatic generation method of the dimensional design drawings and the automatic generation device of the three-dimensional design drawings using the same as the image information.

First, as shown in FIG. 3, two-dimensional design drawing information (hereinafter, abbreviated as A, B1, B2, and C) may be received and stored in the memory module (S11). The two-dimensional design drawing information may be received from a website, a server, a device such as a terminal of an external user, or may be created and stored by user input information.

The two-dimensional design drawing information may include the member list information A, the drawing structure information, and the structural general information C.

The member list information (A) is a shape and a size (size) for each kind of member such as a column, a beam, and a slab as shown in FIG. It may include information about the specification of the main root.

The drawing structure information may include plan view information B1 and cross-sectional information B2 mainly created by a program such as CAD as shown in FIGS. 4B and 4C as design information regarding a structure of a building. In addition, although not shown, multidirectional drawing information in which the building is designed in other directions may be included.

The structural general information C may include information about a supply method of reinforcing bars I according to construction conditions, as shown in FIG. 5. In other words, the structural general information (C) is not only information about the shape and size of the reinforcing bars (I) for each member, but also the rebar processing method and the reinforcing bars (I) in the joint situation where the bars (I) are continuously connected. It may include a method of processing the reinforcing bar in the unconnected settlement situation. Such structure general information C can be described in the two-dimensional design drawing information as text information, table information, and image information.

The drawing analysis module may generate the member drawing information by referring to the 2D design drawing information stored in the memory module (S13). The member drawing information may relate to drawing information in which the member list information A and the drawing structure information are matched with each other. In other words, the member drawing information is a drawing that includes information on each member by matching information on the type and structure of each member included in the member list information A with the building design structure included in the drawing structure information. Can be generated with information.

When the member drawing information is generated in this way, the 3D design module may generate the first 3D design drawing information D1 through this (S15).

Similar to the existing three-dimensional drawing information, the first three-dimensional design drawing information D1 calculates the width information of the building from the floor plan information B1, calculates the height information from the cross-sectional information B2, and combines the three. It may include drawing information about the dimensional space. In this case, the first 3D design drawing information D1 may include member connection information regarding a connection structure between the respective members with reference to the member list information A. FIG.

As described above, the first three-dimensional design information is generated by the three-dimensional design module and the reinforcing bar supply information required for the building can be generated through the rebar analysis module (S17).

The reinforcing bar information may include connection information of reinforcing bars I for each member, shape processing information of reinforcing bars I, supply quantity information of reinforcing bars I, length information, weight information, and the like. This can be generated by recognizing the above structure general information C.

When reinforcing bar information is generated, the reinforcement degree analysis module may generate reinforcing bar reinforcement information M (S19).

Reinforcing bar reinforcement degree information M is drawing information about the structure in which reinforcing bar I is located in a building, and can be generated with reference to member drawing information and reinforcing bar supply information. Specifically, the reinforcing bar reinforcement degree information M can match the member list information A and the reinforcing bar supply information with each other to calculate installation structure information for which the reinforcing bar I should be arranged for each member. At this time, by the combination of the drawing structure information and the member list information A, the reinforcing bar connection information regarding the connection of the reinforcing bars I can be generated with reference to the part connecting information about the connecting structure for each member. When reinforcing bar information is generated, rebar reinforcement degree information (M) about the reinforcing frame of the building is referred to by referring to the reinforcing bar information included in the reinforcing bar supply information when connecting or not. Can be generated as shown in FIG.

When the reinforcement degree information M is generated, the 3D design module combines the first three-dimensional design information and the reinforcement degree information M generated through the member drawing information to include the second reinforcement degree information M 3. Dimensional design drawing information D2 may be generated (S21).

The three-dimensional design module finally includes the second three-dimensional design drawing information (D2) generated as described above, including reinforcing bar information (P) relating to the shape machining and quantity of the reinforcing bar (I) calculated by the reinforcing bar information. As shown in FIG. 6, 3D design information D2 and P may be generated.

The reinforcing bar information P may be processing information of the bar I regarding the shape, quantity, length, weight, and the like of the bar I included in the second three-dimensional design drawing information D2.

Therefore, when the 3D design information is generated, the user may convert the 2D design drawing information into the 3D design drawing information through a simple operation of inputting the 2D design drawing information into the automatic generation device. In addition, the generated 3D design drawing information includes reinforcing bar reinforcement information M and reinforcing bar processing information P, so that no additional work for calculating the corresponding information may be required.

In addition, although not shown in the present embodiment, the three-dimensional design information may include construction information calculated through the rebar processing information (P).

The construction information may include construction period information and material cost information related to the construction of the building.

The construction period information may be calculated by comparing the generated three-dimensional design information with existing design database information stored in the server. In other words, the existing construction design information and the existing construction information which is the information about the result of the building construction actually carried out according to the design drawing information may be stored in the server. Therefore, when new three-dimensional design drawing information is generated, the existing design drawing information can be compared with the structure, shape, material, and the like. When the similarity information of the drawing is calculated according to the comparison result, the construction period information of the currently scheduled building may be calculated by matching the construction period information of the existing construction information with the similarity information.

In the same way, the material cost information can also be calculated using the similarity information compared with the existing construction information.

In addition, the automatic generation device of the present invention can reduce the processing cost of the reinforcing bars (I) in the reverse auction method. The three-dimensional design drawing information calculated through the present invention includes rebar machining information (P). In this case, the communication module (not shown) of the automatic generating device may transmit the generated rebar processing information P to a communication network such as a rebar server that can be connected to rebar processing companies. When the rebar processing information (P) is uploaded to the rebar server, rebar bidding information may be generated and transmitted to the terminal of the relevant company so that the rebar processing and material supply may be performed at the lowest price.

Furthermore, the automatic generation device may receive the corrected 2D design drawing information when the 2D design drawing information, which is input information, is generated while the 3D design drawing information is generated. In this case, the automatic generation device may generate correction information that is change information of the existing two-dimensional design drawing information and the modified two-dimensional design drawing information through a correction module (not shown).

The correction information may include correction drawing information regarding the change in the drawing structure and correction rebar information about the change information of the reinforcing bar I. Accordingly, the automatic generation device may generate modified three-dimensional design drawing information corresponding to the modified two-dimensional design drawing information through the correction information, wherein the corrected information is compared with the existing information as text information, table information, and image. It can also generate information.

According to the 3D design drawing automatic generation method using the 2D design drawing and the 3D design drawing automatic generation device using the same, the 3D design drawing information including the reinforcing bar information corresponding to the 2D design drawing information can be automatically converted. have. In addition, by implementing the detailed functions related to the reinforcing bar information, it is possible to maximize the user's ease of use, and to improve the design reliability by having a series of automated processes irrespective of the user's skill.

7 is a diagram for describing a method of generating recommended reinforcing bar information through drawing analysis according to another exemplary embodiment of the present invention.

In the method of automatically generating a three-dimensional design drawing and the three-dimensional design drawing automatic generating device using the two-dimensional design drawing of FIGS. 1 to 6, the automatic rebar processing drawing generating device is connected between reinforcing bars by referring to the member drawing information and reinforcing bar supply information. It was calculated whether or not and how to respond when connected or disconnected.

In this embodiment, a method for automatically calculating information on reinforcement of reinforcing bars through analysis of member drawing information will be described.

First, the rebar analysis module may analyze drawing structure information of the member drawing information. Drawing structure information shows the structure of a building by a line, a point, a surface, etc., and may include length information of each line.

Accordingly, the reinforcing bar analysis module may recognize the image information shown in the drawing structure information and generate drawing analysis information including length information of each line and connection angle information about the connection portion of the line.

The drawing analysis information may include member connection information regarding a connection between a member and the member. In other words, the member connection information may include only information on the member-to-member connection structure without the information on the structure of the reinforcing bars.

As such, when the drawing analysis information is generated, the reinforcement degree analysis module generates the recommended reinforcing bar information table T and the corresponding drawing analysis information stored in a database of a memory module or an external server to generate reinforcing bar connection information corresponding to the member connection information. Can match each other.

The recommended reinforcing bar information table (T) is a rebar connection method that can be optimally applied in consideration of machining cost, reinforcement strength, construction history, and machining time according to the member connection information of the drawing analysis information. It may be table information storing information on required rebar quantity, connected rebar length, weight, and the like.

Therefore, if the length of the connection part between the members is 1000 mm and the connection angle is 70 ° in the member connection information included in the drawing analysis information, the cost, strength, construction history, and machining time corresponding to the corresponding length information and the connection angle information In consideration of this, a plurality of recommended reinforcing bar information may be automatically generated, such as first recommended reinforcing bar information, second recommended reinforcing bar information, and third recommended reinforcing bar information according to priority.

The recommended reinforcing bar information may include information about a reinforcing bar connection method (joint, fixation) corresponding to the member connection information, a shape, a quantity, and the like.

The recommended reinforcing bar information may be sequentially provided with a specific item prioritized according to the user's setting.

In addition, when the user does not satisfy the recommended reinforcing bar information, the user may directly input information on each item through the user input module. In addition, the control module may transmit the drawing analysis information to the expert terminal associated with the building, and receive the recommended reinforcement information as response information from the expert terminal.

When the recommended reinforcing bar information corresponding to each drawing analysis information is generated, the 3D design module may convert the generated plurality of recommended reinforcing bar information into reinforcing bar degree information.

According to this method, the reinforcing bar information can be automatically generated by analyzing the shape of the drawing rather than matching the member drawing information and the structural general information.

8 is a diagram for describing a method of generating substitute reinforcing bar information reflecting a site situation according to another exemplary embodiment of the present invention.

In the exemplary embodiment of FIG. 7, the recommendation rebar information, which is reinforcing bar information, is automatically generated by analyzing the drawing in the drawing design step. On the other hand, in the present embodiment, in the state in which the member drawing information primarily includes the reinforcing bar connection information between the members, it is possible to generate replacement reinforcing bar information replacing the existing reinforcing bar connection information reflecting the situation of the construction site.

For example, in the construction of a building according to the information of the reinforcing bar, the change of the design structure, the change of the construction period, the change of the climate, the change of the construction company, the change of the construction cost, and the like, the change of the government policy may occur.

When such a site change situation occurs, the user may input field change information on the corresponding change through the user input module of the automatic generation device 100.

When the site change information is input, the control module may generate replacement reinforcement information CT which is reinforcing bar connection information corresponding to the site change information.

The replacement reinforcement information may be generated through a replacement reinforcement table (IT) stored in a memory module or an external server.

For example, when a change in the design structure for the reinforcing bar connection site occurs at the construction site, the user may input site change information about the reinforcing bar into the user input module.

When the rebar analysis module and the reinforcement analysis module receive the site change information, the rebar analysis module and the rebar analysis module may retrieve reinforcing bar connection information corresponding to the changed design structure from the replacement reinforcing bar table (IT) of the memory module or an external server.

When reinforcing bar information is found in the replacement bar table IT, a plurality of replacement bar information CTs may be generated and output to the display module according to a predetermined priority to inform the user.

The user may check the output of the plurality of replacement reinforcing bar information CT and input selection information for the replacement bar information corresponding to the current situation.

When the selection information for the replacement reinforcement information is input, the drawing analysis module generates the part drawing information reflecting the replacement reinforcement information, and the 3D design module generates the rebar work drawing information and the change information about the changed contents. can do.

In this way, as the replacement reinforcing information is automatically generated according to the site situation, the user can respond more efficiently to the rapidly changing site situation.

The method for automatically generating a 3D design drawing using the 2D design drawing using the design drawing as described above and the apparatus for automatically generating a 3D design drawing using the same are not limited to the configuration and operation of the embodiments described above. The above embodiments may be configured such that various modifications may be made by selectively combining all or part of the embodiments.
