Plane intersecting truss demolition method
The invention relates to the technical field of truss demolition, in particular to a plane intersecting truss demolition method. The plane intersecting truss demolition method comprises the steps thatafter a middle connecting rod is hoisted and demolished, a supporting jig frame is arranged at the intersecting position of a first main truss and a main annular truss; then first annular secondary trusses on the two sides of the main annular truss are dismantled, meanwhile, second annular secondary trusses which are adjacent to the main annular truss and intersect with a second main truss are reserved, and dismantling is sequentially carried out according to the sequence that the second main truss is hoisted and dismantled firstly and then the second annular secondary trusses are hoisted anddismantled; then the main annular truss is dismantled; and finally, the first main truss is dismantled in a segmented mode according to the position of the supporting jig frame. The dismantling method of the plane intersecting truss is free of special requirements for field sites, good in safety and easy to operate.
本发明涉及桁架拆除技术领域，具体涉及一种平面相交桁架的拆除方法，包括：吊拆中间联系杆后，在第一主桁架和主环向桁架的相交位置设置支撑胎架；然后拆除所述主环向桁架两侧的第一环向次桁架，同时预留与所述主环向桁架相邻，且与第二主桁架相交的第二环向次桁架，按照先吊拆所述第二主桁架，再吊拆所述第二环向次桁架的顺序进行依次拆除；接着拆除所述主环向桁架；最后根据所述支撑胎架的位置对所述第一主桁架进行分段拆除。本发明提供了一种对现场场地无特殊要求、安全性好、操作简单的平面相交桁架的拆除方法。
