[0010]

FIG. 1 is a block diagram showing the overall configuration of an embodiment of the present invention. Among the various types of bridges, the completed linear data A of the bridge of the bridge type to be designed and manufactured is stored in means 1 such as a first memory.
, The second means 2 obtains the production system linear data B. The respective linear data A and B are calculated by the calculating means 3, the third means 4 which is a design drawing creating means obtains a design drawing as shown in FIG. 5 described later, and is a production data creating means. The fourth means 5 obtains part information at the time of production for each part and also obtains a working drawing. The part information is, for example, the shape and attributes of the members constituting the bridge, and the attributes are information such as welding, the mounting position with other members, and the like.

[0011] Thus, the linear data defines the road surface shape of the road on the bridge, and the data A of the three-dimensional bridge model, which is a completed system model, indicates the bridge structure by (1) bridge → modeling unit → block → panel. → Define in the hierarchical structure of member｝. The three-dimensional bridge model data B, which is a production system model, is obtained by adding a camber value to the three-dimensional bridge model (completed system) data and converting the data into dimensions and coordinates of the production system.
The model structure is the same as the completed model for design.

As for the completed linear data A, when editing the linear data, as shown in FIG. 2, the basic shape lines necessary for defining the three-dimensional bridge model, that is, the vertical lines and the crossing lines are aggregated. prepare.
The line data is input by the input means 6 to input the linear coordinate value of the bridge, or is input from the linear calculation means 7, and further adds structural characteristics to the fetched line. A line attribute is provided as indicated by reference numeral 8. Therefore, from FIG. 1 and FIG.
The first means 1 constitutes a signal output means.

Next, based on the result of the linear data editing shown in FIG. 2, as shown in FIG.
The arithmetic processing is performed by First, in the modeling reference line arranging means 9, lines such as a vertical girder line, a vertical rib line, a deck edge line, a horizontal rib line, and a field joint line which are not defined in the above-described linear data editing and are necessary for the modeling are set. Define.
In the stiffener arrangement means 10, a vertical stiffener and a horizontal stiffener are allocated. Further, in the means 11 for designating a crossing structure type, various structure types included in one crossing line are specified. For example, focusing on a cross section, if it is composed of a bracket, a diaphragm, a cross beam, and a bracket, a structure type is assigned to each line segment in the cross section to facilitate modeling.

Further, the means 12 for allocating the steel slab is a dedicated menu for examining the allocation of the vertical ribs, the horizontal ribs, the joint positions, etc. on the steel slab, and can be used before starting the design. . You can also start modeling right away.

In this way, the linear data edit shown in FIG. 2 and the line defined by the layout and structure edit shown in FIG.
Attach the cross section model to each structural unit as shown in
Model the completed system with the basic structure of the bridge. Attach a cross-sectional model to each structural unit on the line defined by linear data editing and layout / structure editing to model the basic structural part of the bridge. Regarding the modeling 13 of the sheet girder bridge, the box girder bridge, and the steel deck slab girder, in the cross-sectional models 14 to 17, the types of members constituting the cross-section such as the upper flange, the web, and the lower flange and the attributes thereof are defined in advance. ing. The attributes include the type of restraint on the plate side, the shape of the weld groove, the mating member to be attached, and the like, and also the welding size, that is, the design data of the completed system of the member. Furthermore, there are modeling of stringers, field joints, and corner structures 18 to 20, and the like. Therefore, from FIGS. 1 and 3, the configuration (9 to 12) in FIG. 3 and a part of the calculation means 3 constitute a complete system three-dimensional model generation means.

The computing means 3 inputs such modeling input data from the means 21 as shown in connection with FIG. The operation means 3 includes an operation method 3a common to all bridge types and an individual operation method 3 different for each bridge type.
b, and the calculation is performed using the common calculation method 3a and the individual calculation method 3b. Table 1 shows the types of structures obtained by the specific operation programs of the operation methods 3a and 3b.

In Table 1, for example, sheet girder bridge, box girder bridge,
Of the structural types of steel deck slab bridges, the diaphragm is described as "common 1" in Table 1 in that it means that a common calculation method for a diaphragm common to all bridge types having a box cross section is used. In addition, those with no “co” and no subscript number mean that a program of an individual calculation method is used.
