Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with the drawings and specific embodiments, the utility model is described in detail.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of GIS building structure for the integrated roofing framework of 500kV transformer station, for all-steel building structure, mainly comprise GIS room rigid frame 1 and the outdoor framework 2 of GIS, described GIS room rigid frame 1 adopts double-slope roof portal frame structure, and its main body is formed by connecting primarily of rigit-frame beam 11 and rigid-frame column 12.The outdoor framework 2 of described GIS is positioned at rigid frame 1 top, GIS room, and it is formed by connecting primarily of frame girder 22 and truss column 23.In order to avoid the deadweight of the outdoor framework 2 of GIS directly causes rigit-frame beam 11 to occur bending and deformation, prevent GIS room rigid frame 1 bulk deformation, the rigid-frame column 12 in GIS room rigid frame 1 directly can be fixedly connected with between the truss column 23 in the outdoor framework 2 of GIS.In order to improve the outdoor framework 2 of GIS plane in integral rigidity, the frame supports part 21 of " people " font is set in the middle part of the outdoor framework 2 of GIS, one end and the frame girder 22 of described frame supports part 21 are connected and fixed, and the other end and truss column 23 or rigid-frame column 12 are connected and fixed; Especially, if when the other end of frame supports part 21 and rigid-frame column 12 are connected and fixed, because rigid-frame column 12 is the main body keel piece of GIS room rigid frame 1, therefore, the integral rigidity of the outdoor framework 2 of GIS can be made to strengthen further, improve its be fixedly connected with GIS room rigid frame 1 after stability.
As shown in Figure 4, Figure 5, the top board 6 of steel is welded and fixed on described truss column 23 top, described frame girder 22 link is welded and fixed the end bracket 8 of steel, hinged fixing by high strength connecting bolt 5 between described top board 6 and end bracket 8, described connecting bolt 5 arranges several, and be uniformly distributed on end bracket 8, to ensure to be connected stressed uniformity and reliability between top board 6 with end bracket 8.Described frame girder 22 adopts square tube joist steel component, in order to improve the firm welding of end bracket 8, first can be welded and fixed the bearing plate 3 of steel at the link of frame girder 22, then, bearing plate 3 and end bracket 8 is welded and fixed.Further, leg-of-mutton gusset 4 can also be welded and fixed between bearing plate 3, end bracket 8, and described gusset 4 and bearing plate 3, welded seam width between end bracket 8 are 12mm, to ensure the fastness that gusset 4 welds with between bearing plate 3, end bracket 8 and reliability.In order to improve the bonding strength between bearing plate 3 and frame girder 22, improve flexural strength and the torsional strength of frame girder 22, can be welded and fixed some pieces of floors 7 between bearing plate 3 and frame girder 22, and the welded seam width between floor 7 and frame girder 22 is 6mm.Described floor 7 is trapezoidal plate, and hoop truss beam 22 is uniformly distributed.Adopt the GIS building structure of said structure, be not only convenient to dismounting, the construction progress of construction work can be significantly improved, and the integral rigidity of building structure can also be significantly improved, strengthen its reliability, stability.
When the site earthquake intensity of 500kV transformer station is high, or when having a clear and definite high request to its construction progress, on the basis adopting above-mentioned GIS building structure, truss column 23 in the outdoor framework 2 of rigid-frame column 12 in described GIS room rigid frame 1 and GIS all adopts I-shaped steel section, and integratedly between rigid-frame column 12 with truss column 23 to connect, also namely, more than roofing is directly extended upwardly to as truss column 23 by rigid-frame column 12 top in GIS room rigid frame 1, as shown in Figure 1, Figure 3.Because I-shaped steel section has very high flexural strength, the deflection deformation amount when being subject to sharp pounding is very little, and integrated connected mode has higher bonding strength than combination connecting modes such as welding.Therefore, adopt this structure not only to make the anti-seismic performance of GIS building in 500kV transformer station better, and its speed of application is fast; In addition, compare the plan of establishment that the outdoor framework 2 of GIS is located immediately at ground, its relative altitude becomes apart from GIS room roofing height from height off the ground, thus while the rolled steel dosage reducing the outdoor framework 2 of GIS by a relatively large margin, also save the floor space of the outdoor framework 2 of GIS, and can construction speed be significantly improved, therefore, reduce construction cost, saved land resources, obtain good economic benefit.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; it should be pointed out that all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
