Abstract

The invention provides a method for drawing a diaphragm plate positioning line after a curved surface steel box bridge web is unfolded, and belongs to the field of curved surface steel box bridge design. According to the method, the problem that positioning of the diaphragm plate calibrated on the web expansion graph is tedious in the deepening design of the steel box bridge construction drawing is solved and errors are solved., Key points of the technical scheme are as follows: expanding the web of the curved steel box girder into a plane, extracting arc length data of a web curve segment between diaphragm plates on a plane projection drawing, a data calculation table, calculating, filling diaphragm plate numbers in the table, calculating accumulated arc lengths and diaphragm plate positioning line coordinates, and inputting fields of commands, coordinates and texts into the diaphragm plates; copying data of a'partition plate positioning 'column in the data calculation table; openinga web plane expansion graph, inputting a line drawing command, pasting the copied data to a command bar, and completing drawing of all partition plate positioning lines; copying data of an input number column in the data calculation table; and pasting the copied data to the command bar to complete the numbering of all the clapboards.

Description

technical field [0001] The invention relates to the technology of the drawing method of the deepening design drawing of the steel box bridge, in particular to the technology of the drawing method of the positioning line of the transverse diaphragm after the web plate of the curved steel box bridge is unfolded. Background technique [0002] In the workshop manufacturing and assembly process of steel box bridges, it is necessary to select the positioning method of the diaphragm according to the structural characteristics and process of the bridge. When adopting the assembly method of locating the diaphragm on the web, it is necessary to mark the position of the diaphragm on the web expansion diagram so that the workshop can directly measure the size during assembly. For steel box bridges with planar curves, the distance between the diaphragms on the unfolded web is often not equal. Usually, the "offset" command is used to draw the positioning lines of the diaphragms one by one...
