Description
Technical field
The utility model relates to a kind of novel substation framework A type node, for the tip position of framework, belongs to technical field of power systems.
Background technology
Along with the develop rapidly of power industry, transformer substation construction quantity cumulative year after year.Due to the development of electrical reticulation design technology, power transformation engineering electrical wiring form and equipment are pursued compact and reasonable and are arranged, the frame design matched with it becomes the design received much attention.Guaranteeing that under the prerequisite that substation project is safe and reliable, economic stability is run, reasonably optimizing framework is arranged, adopting legerity type just to connect tubular joist structure, optimizing frame structures and arranging and rod member section, effectively can save steel, reducing construction costs.
The utility model is carried out and is just connect the research of girder truss in 220kV substation framework, traditional beam-column hinged structural system of 220kV substation framework is changed into and just connects structural system, cancel column cap gusset plate, reduce English truss beam section height, design a kind of novel substation framework A type node.The methods such as money investigation, mechanical calculation, comparative analysis are searched in employing, determine rational form of structure, solve the difficulties of this novel substation framework in design, calculating;
The research of the just adapter girder system of legerity type is a new problem in power construction, as obtained successfully, substation framework will be made to design make a breakthrough in structural shape, steel using amount, succinct profile, fully show the modern transformer substation framework structure construction level that simple for structure, technique is first-class, can be State Grid Corporation of China and provide reliable engineering experience and theoretical foundation in transformer substation framework design, application from now on.
Light section steel structure is a kind of form of structure of China's keypoint recommendation in recent years, and it has lightweight, and moulding is lightly attractive in appearance, and speed of application is fast, the features such as good economy performance, particularly triangle space steel pipe truss structures (all rod members all adopt round steel pipe).At present, adopt the building of this tubular joist structure substantially to belong to public building, in the facility such as waiting hall, departure hall, stadiums, application trend is further extensive at the train station.
Use frame girder for triangular truss beam in current domestic electrical construction, but girder truss still connects web member and chord member by gusset plate, the material of web member is based on angle steel, and the round steel pipe trussed construction of directly welding is applied seldom in power engineering.And the key of round steel pipe truss is exactly tubular joint.
Therefore, tubular joint is the emphasis of steel pipe truss research, does not all adopt the special technology code of the steel pipe truss of tubular joint at present both at home and abroad, and the design of this kind of tubular truss is all carried out with reference to general truss structure design.China's specification be then to compression boom at Nodes according to hinged process, obviously too conservative.Therefore in steel work, reasonably use steel pipe truss structures, improve computation model, greatly can improve the resistance to overturning of structure.
