Description

The present invention relates to a design support computer for designing and producing a steel structure, an NC control processing machine, and a steel structure component which is a process computer for providing processing data to the NC control processing machine. Related to a manufacturing apparatus.

[Conventional technology]

2. Description of the Related Art In the production of a steel structure, conventionally, drawings of the entire and partial details of the steel structure are designed, and then, detailed drawings of the entire structure for production are designed. Based on this, necessary parts are arranged, the actual size data of the necessary parts is created, the necessary parts are manufactured by processing the steel frame material based on this actual size data, and the necessary parts are welded, bolted, etc. Is assembled into a predetermined small part unit (product) of the steel frame structure. The product is transported to a construction site where it is used as part of a structure.

Recently, CAD systems and CAM systems have been developed to facilitate this type of design, and furthermore, there has been an attempt to combine NC control with them to automate from design to production.

[Problems of the prior art]

However, this is limited to bridges in which both the structure and the joints are patterned, and NC processing involves cutting, drilling,
Batch processing for each lot is partially performed for each processing step of groove processing, and the degree of freedom of design, that is, applicable steel structure, is extremely limited, and the degree of freedom of automatic processing, that is, application There is a problem that the processing that can be performed is also extremely limited.

Steel structures have a large number of components and a wide variety of types and sizes of rolled structural steel used as parts, and the number of detailed patterns of these joints can be considered numerous, so the parameters that determine the design are diverse. . Thus, no matter how standardized, it is difficult to consistently combine CAD and CAM systems and even NC controlled machining. In the end, despite the inevitable production of parts, it is impossible to drastically improve production efficiency because it relies on batch production for each lot. Further, since the plate is punched for each lot after cutting the plate, it takes a lot of trouble to handle the plate. On the other hand, in order to operate the NC processing machine from the design drawing via the CAM system, not only did it require extremely large efforts to create and check the data, but also unavoidable check omissions and mistakes, It was also a cause.

NC control machining requires extremely large amounts of labor to create machining data from a design drawing, and is therefore limited to a relatively limited number of machining steps for parts that require a relatively large amount of machining. There is also an attempt to go one step further from the so-called CAM system that takes full-scale data from the automatic machine drawing system to NC control machining, but since the design itself is so diverse, it is limited to those that can pattern both structures and joints and at the same time design Creating the input data from the diagram to the system also requires a great deal of effort. On the other hand, there is a design movement using an interactive CAD system, but since the drawing of the design drawings has been completed, it is difficult to use CAD data as it is as input data for the CAM system for production, Patterning and standardization of drawings make it difficult to search for accumulated data, and at the same time, it is not easy to modify even a slight change in design conditions, and it is difficult to reuse the data. In this way, in order to link the CAD data of the design and the CAM data of the production and combine them with the machining equipment controlled by NC control to achieve consistent automation of multi-product small-quantity production, various designs become the biggest bottleneck, and data creation Not only does this require an extremely large amount of labor for checking, but also causes omissions and checking mistakes, which can lead to erroneous parts.

It is an object of the present invention to maximize the effects of design standardization while allowing various designs of steel structures, and to perform automatic design and production with high productivity, flexibility and reliability. And

[Means for solving the problem]

The apparatus for manufacturing a steel structure component according to the present invention arranges detailed design data of each end of a member around a node of the steel structure with respect to a part of a member and a type of a shape steel to be used, standardizes design data, and standardizes design data. A stored standard design value file, a special joint design standard value file that stores design data in which detailed design data of a special joint not standardized in the standard joint file is standardized for each special joint pattern, and a steel structure structural member. Structure definition image creating means for defining specifications and their arrangement, settlement processing means for reading design data of the standard value file, editing design data of each node of the structure, and determining the accommodation of members at each node, Interference processing means for eliminating interference between constituent members in the above, detail processing means for generating additional part information and processing information required for joining members at each node, Simulation processing means for creating data of actual members and additional parts from the results of the design processing described above, drawing creating means for creating image information indicating the arrangement of the constituent members and additional parts, and the finished shape of the assembled state; Manufacturing of steel structure parts including processing data editing means for editing the processing information of the constituent members and additional parts into the actual size data corresponding to each part, and production planning means for allocating the processing data of the constituent members and additional parts to the material An information creating device; and a marking means for attaching a processing index such as a specified part shape and a processing position to the material based on the processing data created by the steel structure article manufacturing information creating device; and a designated position of the material. Drilling means for drilling holes in a hole, cutting means for cutting a specified position in a material, and a groove adding means for forming a specified groove at a specified end Comprising a; unit, Steel parts processing device including a.

[Action] Since the design drafting procedure is changed from the design stage (CAD system) to the actual processing procedure, the actual data is processed and the complete form of automatic design is performed from the manufacturing stage, so most of the input data of the CAM system is automatic. Created. Therefore, CA
Efforts in inputting to the M system and wasteful repetition processing due to omission of reading from design drawings and mistakes are greatly reduced.
Misoperation can be prevented. On the other hand, machining procedures are described in terms of elements and generalization for each member end around the node, or those that cannot be generalized are converted into cassettes with the processing procedure and dimensional standard value of the connection as a special connection for each node, and Since the dimensions of each member end connection are standardized with respect to the used portion of the shaped steel, and these are arbitrarily combined and processed at each node unit, various designs can be allowed. In addition, past results are stored not as drawing data but as standard value files of design data or cassette programs and standard value files that store machining procedures and data for special connections, so that past know-how can be easily reused. In addition, by simply changing the standard values, customization is facilitated, and it is possible to efficiently cope with various designs. This integrated CAD /
The CAM system allows flexible combination of NC control processing lined according to CAD / CAM data, material type and processing characteristics and NC control processing by batch for each lot, maximizing the effects of standardization. The automation of multi-product small-quantity production of steel parts corresponding to various structures diversified while utilizing it will be facilitated and the production management will be easy.

The production database (f) is the result of the full-scale processing and the production planning processing using the processing database (e),
This is a data group for performing machining and assembling by NC control as shown in Table 5.

The processing blocks shown in FIG. 2c are collectively and automatically performed in a batch process using the design system 10 according to design or an instruction of the operator. Before and after each of these blocks, the designer or the operator also creates, changes, and adds input data using the design system 10.

Next, a schematic flow of the design A and the work design B by the host computer 11 of the design system 10 and (one of) the design devices 12 to 16 connected thereto is shown. The details of the automatic processing of each block will be described with reference to FIG. 2c.

First, in the design A of FIG. 2a, detailed design data editing A1, design processing A2, and machining design A3 (A3-1 + A3-2) for a typical skeleton of a structure are executed.

In design B of Fig. 2a, design A (A1
+ A2 + A3) is executed again, and production design A4 (A4
-1 + A4-2) is executed.

FIG. 3a shows the relationship between the data file and the flow of the automatic processing performed in the detailed design data editing A1 shown in FIG. 2c.

This detailed design data editing A1 uses the basic design conditions (1, 2), the design standard value A (a), and the processing / joint member standard value file (6) input by the designer to perform the design processing. Completely detailed data (1-7, 7) necessary for A2 is automatically created, and data development / editing (3, 4, 5, 7) is performed in a form that facilitates processing of each subsequent node.

Here, first, 1-1 to 1-6 of the structure definition data (1)
Are the skeleton illustrated in FIG. 4a and the special connection basic parameters illustrated in Table 2, and the member table (2)
Is member data exemplified in Table 1.

These are basic design conditions given by a designer or operator through an image processing terminal or the like. The special connection basic parameters exemplified in Table 2 correspond to the structure definition data (1).
Are defined as attributes of nodes through the image processing terminal as shown in (1) and (2).

In the member attribute generation (101), a section steel type corresponding to the member name / part name (1-4) of the structure definition data (1) is selected from the member table (2), and the selected section steel type is set. The design standard value file A (a) is read as a key, the member attributes are automatically set, and written in (1-7).

The details of the member attributes are shown in Table 4, and the above relationship is shown in FIG. 5a.

As described above, the design standard value file A (a) automatically creates all the member attributes necessary for the design process only by giving the member name / part name and the shape steel type when creating the design data of the structure. It is a file for setting to. With this file, it is possible to perform a design according to a design standard value set in advance by a designer. This file is set so that it can be edited in designer units and building type units.

Fig. 5b shows the specific structure of this file.

The design member code and the constituent material pattern are standardized so that there is a one-to-one correspondence with the member name / part name.

In 3D frame detailed data generation (102), member attribute generation (1
The three-dimensional structure design data consisting of the structure definition data (1) after completion of the process of 01) and the member table (2) can be easily processed for each subsequent node (3, 4, 5). Automatically edit to. The file (3) contains coordinates to be possessed as attributes of the node, the name of the special connection, its basic parameters, and the like. The file (4) is node connection data of members and skeleton surfaces for arbitrarily extracting the separated node attributes and member attributes as required for processing.

When the files 3, 4, and 5 are completed, the skeleton barycentric line transformation (103) is used to obtain the points given by inputting the nodes given by the input, perpendicular to the barycentric line of each member gathered there for each processing surface,
Replaces the skeleton given in the input with the barycentric line of the member.

In the target point reference two member setting (104), for each member gathered at the contact point for each processing surface of each contact point, for the contact point, search for a member that is closest to the clockwise and counterclockwise one member and has a higher priority than the user. Then, two reference members for determining the crossing target point of each two members to be engaged are set, and a member target point pattern is set and written to the file (7).

In the plate fitting pattern setting (105), for each processing surface of each node, attention is paid to two members, each member and the member to be attached thereto, and joint gusset plate generation information and gusset are obtained from the shape steel type, rotation angle, connection code. The closing pattern of the connection plate such as the plate mounting surface number is read from the processing / joining member standard value file (6) and written into the file (7).

This processing / joint member standard value file (6) focuses on two members that mutually engage in the closing pattern of the connection plate such as the plate mounting level, the plate unfolding angle, and the stiffener generation pattern. This file is standardized for each rotation angle and connection code, and is edited for each designer and each building type. The configuration example of this file (6)
FIG. 5c shows an example of the plate attachment level according to the connection code / shape type / rotation angle in FIG. 5d. FIG. 5e shows an example of a stiffener generation pattern.

Through the above processing, the detailed design data (a) shown in FIG. 2b is completed, and the input data necessary for the design processing A2 is prepared.

The processing (103/104/105) is automatically repeated for each processing surface (member processing surface) at each node of the structure.

For example, when the three-dimensional skeleton of the structure shown in the upper part of FIG. 9 is disassembled into the member processing surface, it is as shown in the middle part.

FIG. 7a shows a flow of the automatic processing performed in the design processing A2 shown in FIG. 2c.

This design process A2 uses the detailed design data (a) (FIG. 2b) created by the detailed design data editor A1 and the special connection design standard value (c) and the design standard value B (d). Then, the complete design necessary for the machining design A3 is automatically performed, and the result is written in the design database (d).

First, the closing process (22) automatically fine-tunes the position of the given member skeleton so that each member end can be fitted around each node with reference to the design standard value B (d) if necessary. Is performed.

In the target point setting (222), the intersection of the barycentric lines of the two target point setting reference members obtained in (104) shown in FIG. 3a is set as the target point of the processing member. However, when the reference member exists only on one of the left and right sides, and when the center of gravity of the two members exists on the same line and there is no intersection, the reference member is shown in FIG. 3a. From the point obtained in (103) b. A point perpendicular to the reference axis of the reference member, or b. The point drawn vertically on the reference axis of the reference member is the target point.

Here, the reference axis refers to the center of gravity line / outer outline / inner outline.

These target point setting procedures are repeated twice or, if necessary, three or more times to converge the target point at each node.

Even if the target point once converges, if specified by input,
A point moved by (Δx, Δy), (Δy, Δz), (Δz, Δx) for each surface based on the coordinate axis of the skeleton surface is set as a target point again.

If there is a special connection, the target point is changed in the routine (223) according to the target point change data determined by the special settlement processing program described later. Next, interference processing (23)
Then, each member is arranged with the skeleton that has completed the closing process (22) fixed, and each member end interference part at each node is cut to obtain a material end cut point.
In the routine (231), the priorities of the members at the nodes are compared with each other, and the material end cut points on the barycentric lines of the members are set in the priority order of the member end cuts.

The detail processing (24) reads each member end connection data at each node from the design standard value file B (d), and arranges and shapes the seed plates of various connection plates (diaphragm, gusset, stiffener, rib plate, etc.). To determine.
Further, the position of the member end cut point is changed as necessary. In the routine (242), the design standard value file B (d) of the connection is read and a vertex candidate point of the gusset plate on the processing member side is obtained.

In the routine (243), the design standard value file B for the connection
(D) is read, and a vertex candidate point of the gusset plate on the partner side where the gusset plate on the processing member side is engaged is obtained.

In the routine (244), candidate vertices of the gusset plate obtained in 242/243 are connected to obtain a gusset plate seed plate shape, and the shape is shaped as necessary. At the same time, conditions for unifying a plurality of gusset plates at the same level are set.

If there is a special connection, the cut point / cut line is changed in a routine (245) according to the end-of-material cut point / cut line change data determined by a special detail processing program described later.

In the routine (246), when it is necessary to change the material end cut point, the material end cut point obtained in 231 is corrected. If an irregular cut is required, the cut line and its grade are added.

In the joint processing (25), the design standard value file B (d) is read, and the state of the member connection at the joint position is checked to determine the position of each joint.

The above process is sequentially repeated for each node of the structure, as shown in FIG. 7b, and is automatically repeated.
Here, the processing surface refers to a found surface of a member or a plate perpendicular to a processing direction of the member or the plate. However, only the joint processing is automatically performed repeatedly for each member.

FIGS. 8a and 8b show an example of the outline of a series of these design processes on one processing surface of a certain node. The contents of the design standard value file B (d: FIG. 2b) used for the above processing are as follows: (d-1) Structural outline file, (d-2) Joint standard value file, (d-3) Gusset specification It is a mouth standard value file and a (d-4) bolt arrangement / gauge dimension standard value file.

The structure outline file (d-1) stores the data shown in the right column in FIG. 12a using the data shown in the left column as a key, and accesses the data shown in the left column to read the data in the right column. The structural point file (d-1) stores local detailed dimensions (standard values) common to various details. Figure 12b shows examples of common joint dimensions, “Overlapping allowance for fillet welding A”, “Turn-over welding allowance B”, and “Clearance C with joining material”, and the gusset and shape corresponding to the rotation angle. Example of the positional relationship of steel, clearance, etc.
FIG. 12c shows an example of the determined dimensions for each section steel in FIG. 12d.

(D-2) The joint standard value file gives splice detailed dimensions of the same joint from the joint code and the type of steel. FIG. 13a shows an input for specifying data (left column) and data to be read (right column), and FIG. 13b shows columns on a file accessed by the input. Thirteenth
By designating a joint position and a joint code as shown in the left column of FIG. c, information on the joint specified by the input is written in the designated position as shown in the right column.

(D-3) The gusset connection standard value file gives detailed dimensions of the gusset connection with the connection code and the steel type. FIG. 14a shows an input for specifying data (left column) and read data (right column), and FIG. 14b shows columns on a file accessed by the input. 14th
By designating a gusset position, a joint code, and a steel type as shown in the left column of the figure, the gusset joint detailed dimensions specified by the input are written in the designated position as shown in the right column.

(D-4) The bolt arrangement / gauge dimension file gives the bolt arrangement detailed dimensions for the joint / joint code and the type of steel. When the input shown in the left column of FIG. 15a is given, the access shown in the center column is performed. Read the data shown in the right column.
This causes the information shown in FIG. 15b to be written to the specified location.

Next, the special connection design process (A2-1) of the design process A2
Explanation will be given based on FIG. 2b.

In the special connection design process (A2-1), if there is a special connection such as a column base / panel zone / truss butt, the special connection type name specified by inputting the basic design conditions (A) and its basic parameters are designed. From the detailed data file (a), and from the special finish cassette program module group (f) and the special finish design standard value (c) set in advance by the designer for each special finish pattern, This is to automatically create detailed design data (C) on a special connection required for the design process.

The special connection design processing (A2-1) includes a special settlement processing (213) and a special detail processing (214) as shown in FIG. 6a.

Routine (213) determines the special target point of the member at a special joint such as the pedestal / panel zone / shed truss end, and processes the entire structure to fit (Fig. 7a, 2).
2) pass the data.

The routine (214) performs a joint design process at a special node also represented by the column pedestal / panel zone / shed truss end, determines the shape, arrangement, and bolt arrangement of various plates, If necessary, cut point data / cut line data or one of multiple plates
This is to generate plate processing conditions such as stripping and pass the data to detail processing (FIG. 7a, 24) of the entire structure.
As shown in FIG. 6b, the special connection design standard value file (c) is configured such that complete detailed data of the connection is read using the type of the special connection and its basic parameters as keys.

FIG. 6c shows an example of a specific reading relationship of a special zone type, taking a panel zone / a haunch as an example.

The above processing is automatically repeated for each special connection node of the structure for each processing surface.

Next, FIG. 16b shows the contents of “simulation processing” A3-1 of the processing design A3 shown in FIG. 2c. This simulates a process similar to when actually machining a part with a computer,
This automatically generates data for work (parts processing). When this subroutine is specified by an input and a certain section of a certain structure created in the above-described design processing is specified by a designer or an operator, the design data
The design data group for the section in the database (FIG. 2b) is specified, and based on this, the processing in FIG. 16b is automatically and repeatedly executed for each part.

That is, the design system 10 first defines (generates) and arranges (assembles) pieces (section steel) based on the processing condition data in the design database, and then creates pieces (various steel plates: diaphragm / stiffener / rib / gusset). Define (generate) and arrange (assemble) (33
1). Next, based on the design conditions, a plurality of steel plates (gussets / diaphragms, etc.) at the same level are integrated (composite), and a built-up section steel is defined using the pieces (steel plates) determined in the above subroutine 331. , And disassemble parts of rolled steel into built-up steel (steel plate) (33
2). Next, based on the processing condition data of each part in the design database, the members are cut (mainly in a panel zone), and the members are lengthened / shortened, and then cut (mainly, material ends and joints). Alternatively, pieces are cut together, pieces are cut with pieces, or pieces are cut with pieces. Alternatively, the member or the piece is cut by a figure (line, closed figure). Alternatively, a part of the flange of the H-section steel (member or piece) is cut with a piece (gusset plate) (333).
Next, a hole is made in the member or piece (334). Next, the member or the piece is bent, and the member or the piece is subjected to drawing (cutting / bending) (335). The above processing (331 to 335) is automatically performed for all parts. As a result, all processing information of all required parts is generated in the processing data database.

Next, production management basic data is created based on the data thus generated. That is, basic data relating to production management such as the number of parts, the weight of each part, the surface area, the cutting length, the number of holes, etc. are created (336). Next, it recognizes the connection of parts and determines whether it is in contact with other parts.
Find the number of bolts for each part alignment data, welding line position / shape / length or diameter / neck length (33
7). Next, each component is automatically classified and numbered for each component processing condition such as design mark (member name), size, material, processing shape, position, etc., and a component mark is attached (338). Next, the connection data between the parts is determined, and products having the same assembly conditions for each part are automatically classified and a product mark is attached (339). Then, the processing data and the production management basic data generated as described above are stored in the processing data database.

By the "simulation processing" A3-1, the processing information is generated in the "processing data database" based on the "design data database" generated in A1 "detailed design data editing" and A2 "design processing" described above. It was done.

Next, the "design drawing / work drawing creation / form editing" A3-2 of the machining design A3 shown in FIG. 2c is shown in FIG. 16c and will be described with reference to FIG. 16c. Generate a drawing database at 401-403-404,
At the time of product assembly, subroutine 402-403-404-405
At -406, a drawing database is generated. Then, plot data creation 407 and product inspection list creation 408 are performed based on the drawing database.

More specifically, first, figure / section data of a required part is extracted from the machining data database, coordinate-transformed and scaled (401/402). Next, fit the dimension line /
Dimensions / products / parts marks, materials, etc. are entered (write data to drawing frame) (403). The above processing is performed on all products to create all partial diagram data for each product.
Next, place each partial view on each required drawing in consideration of the scale, and enter the name and dimensions of the overall layout reference line (40
Four). This means that the product data has been organized in the form of a drawing. Further, in the case of product assembly, the number (number) of each product is calculated, and the product mark / number is entered in the required drawing (405). A key plan showing the product arrangement is created and filled in the required drawings (406). Next, if there is any inconvenience in drawing notation such as overlapping of characters or dimensions in the drawing (drawing database) automatically generated as described above, the operator corrects it interactively (409). When generating a product inspection list,
For each product, a list containing dimensions and a figure to be checked at the time of assembly is edited (408) and printed out (414). When obtaining a design drawing / work drawing, the drawing data in the drawing database is converted into the data format of the plotter (407), and the drawing is printed out by the plotter (410-413). In the case of the design drawing of the whole assembly (410), a general drawing or a detailed drawing is obtained by expanding the arrangement of all the products for each skeleton surface and by reducing the scale. The case of the construction drawing (411) is essentially the same as the case of the design drawing (410), but generally only a general drawing is obtained.

In the case of the design drawing of the product assembly unit (412), a part of the factory assembly disassembled in the actual joint unit in which the details of each surface of each part are developed in the product unit is output. Then, in the case of the work drawing of the product assembly unit (413), all of these are output.

The lower part of Fig. 9 shows an example of a general drawing of a design drawing / working drawing, and an example of a working drawing disassembled into product units is shown in Figs.

(FIG. 16, FIG. 16b) and retrieve the part machining shape data with reference to it (461). Next, if there is a bending process, it is developed to obtain a part shape before the processing (462). Next, the alignment type marking data is edited (463). Next, the weld joint shape is determined with reference to the welding line position, length data, shape, and welding standard value, and the welding length is calculated, and backing metal is generated and registered as necessary (464). . Next, the intersection of the welding line is recognized, scalloping is performed with reference to the welding standard value, and the final part shape is determined in consideration of the welding shrinkage margin (465). The above processing is automatically executed for all parts.

Next, the number of the same part mark (the same processing conditions) is calculated, and the part mark / number / material is entered on the part drawing (466). Then, the above-described actual component size data is edited for each drawing output unit and stored in the drawing database. When the output of the current size processing drawing is instructed, the corresponding drawing data in the drawing database is converted into the data format of the plotter (469) and the drawing is printed out by the plotter. FIG. 11 shows an example of the actual size processing drawing. Various production management data obtained by the actual size processing is edited into a form and printed out (468).

Next, in the production design A4 shown in FIG.
A4-2 is shown in Fig. 16e and described with reference to Fig. 16A. First, material nesting is performed by combining a plurality of parts having the same material / size, and the standard length, standard width, and number of materials are determined. In addition, a material lot ID (identification code) is given and a material ID / part ID is given. In the case of a steel plate, the odd-shaped plate is removed interactively using CAD (471).
Next, edit the NC processing data for each lot (47
2). Next, the time required for each processing step is calculated for each lot (473). Next, a processing lot for two to three days is determined based on the construction urgency and the degree of processing urgency in consideration of the number of processing steps in the post-process, and a pile of required processing time for each processing step for one day is the processing capacity of each step. The processing order of each lot is set so that the load of each processing step is balanced as much as possible (474). Then, based on the set lot processing order, a “material receiving schedule data file” and a “material output (processing) sequence data file (including processing specification deletion data) for several days including the processing day are created, and each process is performed. It is transferred to the processing system 30 together with the processing data for each

〔The invention's effect〕

As described above, according to the present invention, the procedure of design drafting from the design stage (CAD system) is changed to the actual machining procedure,
Most of the input data of the CAM system is automatically created because the actual data is processed and the complete automatic design is performed even from the manufacturing perspective. Therefore, the labor of inputting to the CAM system and the repetition processing due to reading omission or mistake from the design drawing can be largely omitted, and erroneous operation can be prevented. On the other hand, machining procedures are described in terms of elements and generalization for each member end around the node, or those that cannot be generalized are converted into cassettes with the processing procedure and dimensional standard value of the connection as a special connection for each node, and Since the dimensions of each member end connection are standardized with respect to the used portion of the shaped steel, and these are arbitrarily combined and processed at each node unit, various designs can be allowed. In addition, past results are stored not as drawing data but as standard value files of design data or cassette programs and standard value files that store machining procedures and data for special connections, so that past know-how can be easily reused. In addition, by simply changing the standard values, customization is facilitated, and it is possible to efficiently cope with various designs.

With this integrated CAD / CAM system, CAD / CAM data and material types,
It is possible to flexibly combine the NC control processing lined according to the processing characteristics and the NC control processing by batch for each lot, so that it can handle various diversified structures while maximizing the effects of standardization. Automated multi-product small-quantity production of steel frame parts is facilitated, and its production management becomes easy.
