Description
Technical field
The utility model relates to substation framework field, is specially a kind of cantilever steel girder that can be used for 220kV outdoor power transformation framework.
Background technology
At present, numerous transformer station having run 20 to three ten years of South China enters the comprehensive reformation stage successively.In many 220kV transformer stations, 220kV framework, bus reach more than 20 year running time, and former precast concrete framework beam column is damaged and crack is serious, and wire is outmoded, and operational reliability is low, therefore changes it.
Because place, district, station is limited and can not again take over the land for use, framework arranges that still maintaining former electric double layer encorbelments framework arrangement form, considers the safe distance requirement of live part and framework, need arrange one section of Cantilever Beams more than 3 meters.Former outdoor structure beam column adopts precast concrete form, and this is considered and turns power reguirements, adopts steel work to be processed by producer, and on-the-spot directly installation is to shorten construction period.We optimize Steel Structure bean column node structure for this reason, cantilever steel girder is connected with ground terminal, more than cantilever steel girder arranges that horizontal gird hangs down lead again.
Summary of the invention
In order to overcome above-mentioned deficiency of the prior art, the utility model provides a kind of outdoor power transformation framework cantilever steel girder, solves the safe distance requirement of relevant charging equipment and framework, also solves the contradiction of land used in station.
The utility model solves the technical scheme that its technical problem adopts:
A kind of outdoor power transformation framework cantilever steel girder, described cantilever steel girder adopts rectangle latticed steel structure, comprise the angle steel chord member that is arranged at corner and support and be fixed on web member between angle steel chord member, described cantilever steel girder is provided with top board in its end top of encorbelmenting, its relative one end of end of encorbelmenting is provided with gusset plate, be supported with horizontal gird above wherein said top board, described gusset plate is connected with ground terminal.
As the improvement of technique scheme, described angle steel chord member comprises the upper chord being arranged at top and the lower chord being arranged at below.
As the improvement of technique scheme, described web member comprises diagonal web member and horizontal web member, is supported fixing between wherein said upper chord and lower chord by diagonal web member, is supported fixing between described upper chord, between lower chord by horizontal web member.
As the improvement of technique scheme, be obliquely installed between described web member and described angle steel chord member, between adjacent web members and described angle steel chord member, form triangle fixed structure.
As the improvement of technique scheme, described top board and horizontal gird, to be all bolted to connection between described gusset plate and ground terminal.
The beneficial effect that the utility model brings has:
This outdoor power transformation framework cantilever steel girder, main employing rectangle latticed steel structure, simple structure, with ground terminal and horizontal gird easy to connect, structure stress is clear, the safe distance solving relevant charging equipment and framework requires and stands interior land used contradiction, and applicability is strong and be beneficial to popularization, has practical value to similar engineering.
Accompanying drawing explanation
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail,
Accompanying drawing 1 is structure side view of the present utility model;
Accompanying drawing 2 is structure top views of the present utility model;
Accompanying drawing 3 is structure sectional views of the present utility model;
Accompanying drawing 4 is Application Example structural representations of the present utility model.
Detailed description of the invention
With reference to accompanying drawing 1 to accompanying drawing 4, the utility model is a kind of cantilever steel girder that can be used for 220kV outdoor power transformation framework, and it can solve the safe distance requirement of relevant charging equipment and framework, can solve the contradiction of land used in station simultaneously.
Concrete, cantilever steel girder of the present utility model adopts rectangle latticed steel structure, it comprises the angle steel chord member that is arranged at corner and support and is fixed on web member between angle steel chord member, the end top of encorbelmenting of cantilever steel girder is provided with top board 5, its relative other end of end of encorbelmenting is provided with gusset plate 6, be supported with horizontal gird 7 above top board 5 wherein, gusset plate 6 is for connecting ground terminal 8.
Further, angle steel chord member can be divided into the upper chord 1 being arranged at top and the lower chord 2 being arranged at below by us, and web member can be divided into diagonal web member 3 and horizontal web member 4 simultaneously.Support especially by diagonal web member 3 fixing between upper chord 1 and lower chord 2, then supported by horizontal web member 4 fixing between upper chord 1, between lower chord 2.Further, be all obliquely installed between web member and angle steel chord member, between the web member adjacent with this and angle steel chord member, will stable triangle fixed structure be formed.
Other, top board 5 and horizontal gird 7, to be all fixedly connected with by bolt between gusset plate 6 with ground terminal 8.
Thus visible, this outdoor power transformation framework cantilever steel girder mainly adopts rectangle latticed steel structure, its simple structure, with ground terminal 8 and horizontal gird 7 easy to connect, structure stress is clear, the safe distance solving relevant charging equipment and framework requires and stands interior land used contradiction, and applicability is strong and be beneficial to popularization simultaneously, all has practical value to similar engineering.
It should be noted that, the above is preferred embodiment of the present utility model, and the utility model is not limited to above-mentioned embodiment, as long as it reaches technique effect of the present utility model with identical means, all should belong to protection domain of the present utility model.
