As further program of the utility model: weld stiffener B between the bottom margin of described cap with end strut segments outer surface.
As further program of the utility model: weld stiffener A between bottom and the top of cap of described shear plate B.
As further program of the utility model: perforate simultaneously after outside composition backing A, shear plate B and the backing plate A4 welding of described shear plate B, it is simple to the pin in grafting pin assembly.
As further program of the utility model: described pin assembly is mainly made up of pin, backing plate B and reinforcing bar, the through hole that wherein pin is offered on shear plate B and shear plate A, and the head of pin offers circular hole, grafting reinforcing bar in circular hole, pin arranges backing plate B with the connecting end surface of shear plate B simultaneously.
As further program of the utility model: the aperture of described circular hole is 10mm, and the diameter of reinforcing bar is 9mm.
Compared with prior art, the beneficial effects of the utility model are: this utility model passes through pin link strut segments and framework side column, it is thus possible to well transmit axle power between side column and end support, simple in construction, facilitates in-site installation simultaneously.

Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of this utility model protection.
Refer to Fig. 1～7, in this utility model embodiment, a kind of attachment structure of transformer substation framework end support and side column, including shear plate A1, end strut segments 2, shear plate B3, backing plate A4, stiffener A5, cap 6, pin assembly 7, stiffener B8, pin 9, backing plate B10, reinforcing bar 11 and circular hole 12, the top of described shear plate A1 is welded on the capital of framework side column, end strut segments 2 is connected by pin 9 with shear plate A1, forms a pin joint, transmits the axle power along end strut segments 2 direction.
The top of described end strut segments 2 connects cap 6, stiffener B8 is welded between the bottom margin of cap 6 with end strut segments 2 outer surface, the intensity of junction is strengthened by stiffener B8, the shear plate B3 that the welded top of described cap 6 two pieces be arranged in parallel, gap is left in the middle of the shear plate B3 that two pieces be arranged in parallel, so that shear plate A1 can insert in the gap between two pieces of shear plate B3, the shear plate B that shear plate A1 and two piece be arranged in parallel is connected by pin assembly 7；Stiffener A5 is welded, to strengthen the lateral rigidity of end shear plate B3 between bottom and the top of cap 6 of described shear plate B3；Perforate simultaneously after outside composition backing A4, shear plate B3 and the backing plate A4 welding of described shear plate B3, it is simple to the pin 9 in grafting pin assembly 7.
Described pin assembly 7 is mainly made up of pin 9, backing plate B10 and reinforcing bar 11, the through hole that wherein pin 9 is offered on shear plate B3 and shear plate A1, and the head of pin 9 offers circular hole 12, grafting reinforcing bar 11 in circular hole 12, avoiding pin 9 landing by reinforcing bar 11, pin 9 arranges backing plate B10 with the connecting end surface of shear plate B3 simultaneously.
The aperture of described circular hole 12 is 10mm, and the diameter of reinforcing bar 11 is 9mm, in order to grafting.
This utility model passes through pin 9 link strut segments 2 and framework side column, it is thus possible to well transmit axle power between side column and end support, simple in construction, facilitates in-site installation simultaneously.
It is far longer than outside each center pillar plane by the curved lateral deformation stiffness that can be provided by owing to the triangular form of framework side column and the truss-like of end strut segments 2 composition supports the lateral deformation stiffness provided, therefore lateral load about more than 90% is born by end support and side column, and the main internal force that lateral load produces on framework side column and end strut segments 2 is side column post limb and the axle power of end support.In Practical Project, substation framework technique load is different, in addition actual wire load to be usually present drift angle from crossbeam different, thus there is more apparent difference in lateral load, can not only well transmit axle power with end strut segments 2 so connecting framework side column by pin 9 and can suitably adjust the lateral load needs that the various engineerings of pin size adaptation are different, reach desired effect.
It is obvious to a person skilled in the art that this utility model is not limited to the details of above-mentioned one exemplary embodiment, and when without departing substantially from spirit of the present utility model or basic feature, it is possible to realize this utility model in other specific forms.Therefore, no matter from which point, embodiment all should be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims rather than described above, it is intended that all changes in the implication of the equivalency dropping on claim and scope included in this utility model.Any accompanying drawing labelling in claim should be considered as the claim that restriction is involved.
