The actual size work of the telescopic device used for the bridge is a work of determining the dimensions and arrangement of each flat plate member constituting the telescopic device based on the design drawing of the telescopic device. Conventionally, the actual size work is performed by manually drawing a member using CAD software, which is often a complicated work. Therefore, there is a demand for a method for performing such work as easily as possible. The program of Patent Document 1 is for supporting the actual size work of the entire bridge, calculates the position of the interpolation point between the points, and derives the dimensions of the members constituting the expansion / contraction device of the bridge. It is not intended to be done.

An object of the present invention is to provide a full-scale work support program capable of suppressing the complexity associated with full-scale work of a bridge telescopic device.

The full-scale work support program of the present invention is a program that causes a computer to function as a means for supporting the full-scale work of a bridge telescopic device, wherein the long direction of the telescopic device is the X direction and the X direction. When the direction orthogonal to both the vertical direction is the Y direction and the vertical direction is the Z direction, the flat plate member constituting the telescopic device while having a pair of side end faces along both the X direction and the Z direction. Based on the member information acquisition means for acquiring the member information indicating the form of the member information and the member information acquired by the member information acquisition means, the X direction, the Y direction, and the X direction and the Y direction at each of the plurality of vertices defining the shape of the flat plate member. It includes a first member form derivation means for deriving a position in the Z direction, and the member information defines one of the upper surface and the lower surface of the flat plate member among the plurality of vertices and one of the pair of side end faces. The apex position information indicating the position in the X direction and the Z direction at each of the plurality of side end apex which is the apex defining the above, the width information indicating the width of the flat plate member in the orthogonal direction, and the plate thickness of the flat plate member. The plate thickness information to be shown is included, and the first member form deriving means is based on the apex position information, the width information, and the plate thickness information, and is other than the plurality of side end apex among the plurality of apex. The positions in the X, Y, and Z directions at the apex are derived.

According to the full-scale work support program of the present invention, the positions of the vertices that define the shape of the flat plate member are derived based on the member information indicating the shape of the flat plate member. The member information includes the position information of the side end vertices that are a part of the vertices that define the shape of the flat plate member, and the width information and the plate thickness information of the flat plate member. As a result, the dimensions and arrangement of the flat plate member can be easily obtained without preparing the position information for all the vertices. In addition, there are various modes in which member information is acquired by the member information acquisition means. For example, the member information may be acquired by the user inputting a value into the computer using an input device such as a keyboard. Further, the member information may be acquired by causing a computer to read the value recorded in a recording medium such as a USB (Universal Serial Bus) memory or a DVD-ROM (Digital Versaille Disc-Read-Only Memory). Further, the member information may be acquired by transmitting the value to the computer through a communication line such as the Internet.

Further, in the present invention, the member information acquired by the member information acquisition means and the first member form derivation means have been derived for the upper plate member and the lower plate member which are the two flat members separated in the vertical direction. The shape of the middle plate member is defined based on at least one of the positions and the thickness of the middle plate member which is a member constituting the expansion / contraction device sandwiched between the upper plate member and the lower plate member. The computer is further functioned as a second member form deriving means for deriving the positions in the X, Y, and Z directions at each of the vertices, and the second member morphology deriving means defines the upper surface of the middle plate member. The position is derived from the position of the apex that defines the lower surface of the upper plate member, and the position of the apex that defines the lower surface of the middle plate member is derived from the position of the apex that defines the upper surface of the lower plate member. Is preferable. According to this, the upper surface of the middle plate member is obtained based on the position of the apex defining the lower surface of the upper plate member, and the lower surface of the middle plate member is obtained based on the position of the apex defining the upper surface of the lower plate member.

Further, in the present invention, the second member form deriving means sets the reference position of the middle plate member with respect to the X direction on the reference plane along both the X direction and the Z direction, and sets the reference position. A second plane parallel to the first plane that is a plane through which the middle plate member is separated from the first plane by a distance corresponding to half the plate thickness of the middle plate member from the first plane along the direction in which the middle plate member spreads. It is preferable to set a first vertex that defines the shape of the middle plate member on the intersection line between the surface and the reference plane. According to this, the form of the middle plate member is easily derived by setting the reference plane and acquiring the reference position and the plate thickness of the middle plate member.

Further, in the present invention, when the first plane intersects the reference plane without being orthogonal to the reference plane, the member information includes information corresponding to the intersection angle between the first plane and the reference plane. The second member form deriving means has the second apex located at the other end of one side having the first apex as one end of the side defining the shape of the middle plate member, with respect to the first plane. It is preferable to set the middle plate member so as not to straddle the reference plane at a position symmetrical to one vertex. According to this, when the middle plate members intersect (obliquely) without being orthogonal to the reference plane, the vertices that define the middle plate member are set so that the middle plate members do not straddle the reference plane. Therefore, for example, when the reference plane is along the surface of any member, the apex is not set so that the middle plate member bites into this member. Therefore, the vertices of the middle plate member are appropriately set.

And information indicating the number of the plurality of middle plate members, and the second member form derivation means of the apex that defines each of the plurality of middle plate members based on the member information. It is preferable to derive the position. According to this, when a plurality of middle plate members are arranged in the X direction, the vertices of each of the plurality of middle plate members are appropriately derived by giving the number of the middle plate members arranged and the interval thereof.

Further, in the present invention, the telescopic device includes a plurality of intra-area members which are members arranged in a plurality of areas partitioned by the middle plate member in the X direction, and the member information includes the plurality of members. Includes area information indicating in which of the areas in the area the members in the area are arranged, information indicating the distance between the members in the area in the X direction, and information indicating the position of the members in the area in the Z direction. It is preferable that the third member form deriving means for deriving the positions in the X direction and the Z direction with respect to each of the plurality of members in the area based on the member information is further provided. According to this, regarding the area partitioned by the middle plate member, the area in which the member in the area is arranged, the interval at which the member in the area is arranged in the area, and the position in the Z direction are given.

The form derivation unit 12 includes a cover face plate 110 and 120, a flange plate 130, a base plate 140 and 150, a web 160 and 170, a rib group 180 and 190, and a stud group 200 based on the member information input to the input unit 11. Information indicating each form (dimensions and arrangement) of and 210 is derived as follows.

For the cover face plates 110 and 120, the flange plates 130, and the base plates 140 and 150, the form deriving unit 12 derives the coordinates of vertices other than the representative vertices based on the steel plate member information. As an example, the coordinates of vertices other than the representative vertices of the cover face plate 110 are derived as follows. The coordinates of the vertex Q1 are the coordinates deviated in the −Z direction by the plate thickness indicated by the plate thickness information from the position indicated by the position information of the representative vertex P1 shown in FIG. Further, the coordinates of R1 can be obtained from the position information of the representative vertex P1, the angle information of the representative side a1, and the width information. The coordinates deviated in the −Z direction by the plate thickness indicated by the plate thickness information from the position of R1 derived in this way are the coordinates of the apex S1. Similarly, the coordinates of the vertices Q2 to Q4, R2 to R4, and S2 to S4 can be obtained from the position information of the representative vertices P2 to P4, the angle information of the representative sides a2 to a4, and the width information. The function of the form deriving unit 12 for deriving the form of the steel plate member constituting the cover / face plate 110 or 120, the flange plate 130 or the base plate 140 or 150 corresponds to the function of the first member form deriving means in the present invention. ..

For the webs 160 and 170, the form derivation unit 12 derives the coordinates of the vertices that define these webs based on the steel plate member information and the web member information. As an example, the coordinates of the vertices of the web 160 are derived as follows. The upper end surface 160a of the web 160 shown in FIG. 6 is in contact with the upper end surface 160a along the lower surface of the flange plate 130. Therefore, the Z coordinates of the vertices P5 to P12 defining the upper end surface 160a are derived based on the coordinates of the vertices of the steel plate member defining the lower surface of the flange plate 130 derived by the form deriving unit 12. For example, the Z coordinates of the vertices P5 to P12 are derived as values equal to the Z coordinates of the vertices of the steel plate member that defines the lower surface of the flange plate 130. Further, the Y coordinates of the vertices P9 to P12 are y3 indicated by the position information of the web member information. Further, the coordinates of the vertices P5 to P8 are coordinates deviated from the vertices P9 to P12 in the −Y direction by the plate thickness indicated by the position information of the web member information. Similarly, since the lower end surface 160b of the web 160 is in contact with the lower end surface 160b of the web 160 along the upper surface of the base plate 140, the Z coordinates of the vertices Q5 and Q6 defining the lower end surface 160b of the web 160 also define the upper surface of the base plate 140. Derived from the coordinates of the vertices of the member. Similarly, the Z coordinates of the vertices defining the upper end surface of the web 170 are derived based on the coordinates of the vertices of the steel plate member defining the lower surface of the cover face plate 120. Further, the Z coordinates of the vertices defining the lower end surface of the web 170 are derived based on the coordinates of the vertices of the steel plate member defining the upper surface of the base plate 150. The function of the form deriving unit 12 for deriving the form of the web 160 or 170 corresponds to the function of the second member form deriving means in the present invention.

For the ribs included in the rib groups 180 and 190, the form deriving unit 12 derives the coordinates of the vertices defining these ribs based on the steel plate member information and the rib member information. For example, the coordinates of the vertices defining the rib 183 shown in FIG. 7 are derived as follows. First, in the rib 183, the upper end surface is along the lower surface of the flange plate 130, and the lower end surface is along the upper surface of the base plate 140 and is in contact with each other. Therefore, as with the web 160, the Z coordinate of the apex defining the upper end surface of the rib 183 is the coordinate of the apex of the steel plate member defining the lower surface of the flange plate 130, and the Z coordinate of the apex defining the lower end surface of the rib 183 is It is derived from the coordinates of the vertices of the steel plate member that defines the upper surface of the base plate 140. Regarding the ribs included in the rib group 190, the Z coordinates of the vertices defining the upper end surface are derived from the coordinates of the vertices of the steel plate member defining the lower surface of the cover face plate 120, and the vertices defining the lower end surface are derived. Z coordinate is derived from the coordinates of the vertices of the steel plate member that defines the upper surface of the base plate 150.

Next, the X and Y coordinates of the vertices T5 to T8 that define the upper surface of the rib 183 are derived as follows. The X-coordinates and Y-coordinates of the vertices that define the lower surface of the rib 183 are the same as the X-coordinates and Y-coordinates of the vertices that define the upper surface of the rib 183. As shown in FIG. 10, reference positions p1 and p2 are set at intervals Δ3 with respect to the X direction on the surface 160c of the web 160 facing the −Y direction. The plane along the surface 160c corresponds to the reference plane in the present invention. Next, planes N1 and N2 (first plane in the present invention) orthogonal to the XY plane, which pass through the reference positions p1 and p2 and have an angle of θ6 (intersection angle in the present invention) with the X axis, are formed. Set. Next, as shown in FIG. 11, planes N11 and N12 (second plane in the present invention) parallel to the plane N1 are set at positions separated from the plane N1 by half of t6. Further, planes N21 and N22 (second plane in the present invention) parallel to the plane N2 are set at positions separated from the plane N2 by half of t6. Then, the apex T1 (first apex in the present invention) of the rib 183 is set on one of the two lines of intersection of N11 and N12 and the surface 160c, and the positions symmetrical with respect to the apex T1 and the plane N1. The vertex T2 of the rib 183 (the second vertex in the present invention) is set to. Further, the apex T3 (first apex in the present invention) of the rib 183 is set on one of the two lines of intersection of N21 and N22 and the surface 160c, and the positions symmetrical with respect to the apex T3 and the plane N2. The vertex T4 of the rib 183 (the second vertex in the present invention) is set to. Here, the vertices T1, T2, T3, and T4 are set so that the rib 183 does not straddle the surface 160c. Specifically, for example, the vertex T1 is set on the intersection of the plane N11 and the surface 160c instead of the plane N12. On the other hand, as shown in FIG. 12, it is assumed that the vertex T1 is set on the intersection of the plane N12 and the surface 160c. In this case, the rib 183'defined by this straddles the surface 160c as shown in FIG. This is inappropriate because it means that the end of the rib 183'bites into the web 160. Therefore, by setting the apex T1 on the intersection of the plane N11 and the surface 160c, the rib 183 is appropriately set as shown in FIG. As a result, when the vertices T1 to T4 are set, the vertices T5 to T8 are set at positions separated from the vertices T1 to T4 by the width w6 along the plane N1. The function of the form deriving unit 12 for deriving the form of the rib corresponds to the function of the second form deriving means in the present invention.

Regarding the studs 215 included in the stud groups 200 and 210, the form deriving unit 12 derives the dimensions and arrangement of the studs 215 based on the rib member information and the stud member information. The dimensions of the stud 215 are derived as indicated by the diameter information and the length information in the stud member information. The arrangement of the studs 215 is derived based on the area information, the interval information and the position information in the stud member information. For example, the X coordinates of the studs 215 of the group G2 shown in FIG. 8 are derived so as to be arranged in the X direction at a distance Δ5 between the two ribs 183 corresponding to the area II based on the rib member information. .. Further, the Z coordinate of the stud 215 of the group G2 is derived based on the position information. The function of the form deriving unit 12 for deriving the form of the stud 215 corresponds to the function of the third member form deriving means in the present invention.
