Embodiment 2
[0034] Embodiment 2 of the processing method for intersecting openings of individual truss web members with large negative differences in the present invention: The difference between this embodiment and Embodiment 1 is that if the actual intersecting openings of the actual rods are wrong on site, then The rods to be processed cannot be directly reprocessed according to the intersecting openings of the existing designed rods. At this time, the reference holes on the reference parts in steps 2 and 3 require technicians to sample the 3D model of the truss. In the computer-aided design software Draw the intersecting line of the intersecting opening, and draw the intersecting line on the reference part according to the size of the intersecting line after accurate lofting in the computer. Roll it into a cylindrical sleeve so that the intersecting lines meet end to end; and in steps 4 and 7, the reference piece is directly set on the outer circumference of the rod to be processed to ...

The invention discloses a method for processing an intersecting hole under larger minus tolerance of an individual truss web member. According to the method, an orifice edge profile curve of a reference hole formed in a reference piece is utilized as a locating basis for an intersecting line of the intersecting hole i.e., the position and the direction of the intersecting hole in the periphery of a to-be-processed rod piece are located by virtue of the orifice edge profile curve of the reference hole, so that the to-be-cut end of the to-be-processed rod piece is directly cut off in a space truss construction site, not only can a needed pipe orifice be processed in the to-be-processed rod piece, but also rod piece raw materials are not needed to be purchased again, subjected to re-lofting processing in a factory and then conveyed to the site, therefore the correction operation difficulty of the to-be-processed rod piece is reduced, the correction efficiency of the to-be-processed rod piece in the construction site is improved, and the construction period of the whole space truss is shortened.
Description
technical field [0001] The invention relates to a processing method for the intersecting opening of individual truss web members with large negative difference. Background technique [0002] At present, due to structural requirements and architectural appearance requirements, most large-scale shared buildings have space tube truss structures with the advantages of light weight, high rigidity, structural stability, and good earthquake resistance. Especially in recent years, space tube truss structures have been used in stations, Widely used in airports, stadiums and other places. Such as figure 1 The space truss shown is assembled and welded by arc-shaped secondary truss 1, double-curved main arch 2 and such as lattice support columns, primary and secondary braces, and other secondary trusses, such as figure 2 As shown, the arc-shaped secondary truss 1 of the space truss is composed of two chord webs 11 arranged in parallel and a diagonal brace web 12 bridged between the t...
