Description
Technical field
The invention belongs to ehv power transmission technical field, relate to the frame structures of a kind of 750kV transformer station, be specifically related to a kind of 750kV transformer station concrete filled steel tube framework.
Background technology
Along with the fast development of China's economy, increasing to electricity needs, therefore, country greatly develops extra-high pressure grade project of transmitting and converting electricity.China's T & D Technology development is very fast, and long distance high-voltage grade technology of transmission of electricity is ripe, and the construction of 750kV high voltage substation produces material impact to China's economy.At present, the 750kV transformer station having built up adopts traditional steel pipe inverted Y-shaped column framework or steel pipe lattice type framework mostly, and steel using amount and floor space are all larger, so need to improve 750kV transformer substation framework structure.
Summary of the invention
In order to solve the technical problem that 750kV substation framework steel using amount is large, floor space is large, object of the present invention will provide a kind of saving steel, saving soil, reduce the 750kV transformer station concrete filled steel tube framework of construction costs.
To achieve these goals, the technical solution used in the present invention is: a kind of 750kV transformer station concrete filled steel tube framework, comprise several line truss columns, and ground terminal, is characterized in that: also comprise several bus truss columns; Several line truss columns are arranged in a linear, and the top of adjacent two line truss columns is provided with line beam; Bus truss column is identical with line truss column quantity, several bus truss columns are arranged in a linear and are set up in parallel on several line truss column sides, on the bus truss column being set up in parallel and line truss column, bus girders is installed, the top of line truss column connects ground terminal by flange; Line truss column is uniform section concrete filled steel tube herringbone column; Bus truss column is uniform section concrete filled steel tube herringbone column.
Because line truss column of the present invention and bus truss column are all the truss columns that adopt concrete filled steel tube to make, at pouring concrete within steel pipe, compare with current employing steel pipe inverted Y-shaped column framework or steel pipe lattice type framework, effective saving steel, save floor space, reduce construction costs, there is significant economic benefit and social benefit.

Fig. 3 is lateral view of the present invention.
In figure: 1-ground terminal, 2-line beam, 3-stull, 4-bus girders, 5-line truss column,, the support of 6-end, 7-bus truss column, 8-steel core concrete column, 9-hound.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.As shown in Figure 1, Figure 2 with shown in Fig. 3: a kind of 750kV transformer station concrete filled steel tube framework, it comprises several line truss columns 5, ground terminal 1; Also comprise several bus truss columns 7; The line truss column 5 of the present embodiment and bus truss column 7 are seven; Seven line truss columns 5 are arranged in a linear, and the top of adjacent two line truss columns 5 is provided with line beam 2; Bus truss column 7 is identical with line truss column 5 quantity, seven bus truss columns 7 are arranged in a linear and are set up in parallel on seven line truss column 5 sides, on the bus truss column 7 being set up in parallel and line truss column 5, bus girders 4 is installed, the top of line truss column 5 connects ground terminal 1 by flange.
Line truss column 5 comprises two steel core concrete columns 8, and steel core concrete column 8 is at pouring concrete within steel pipe; Two steel core concrete columns 8 form concrete filled steel tube herringbone column, and the plane forming concrete filled steel tube herringbone column is outside equipped with hound 9 to improve the stability of line truss column 5; The cross section that is provided with 3, two steel core concrete columns 8 of stull between two steel core concrete columns 8 equates, guarantees the weight capacity of line truss column 5; The line truss column 5 of the present embodiment head and end, first and the 7th line truss column 5 is provided with end support 6, and end support 6 bottoms are concordant with line truss column 5 bottoms, end support 6 tops are fixedly connected with line beam 2.
Bus truss column 7 adopts the structure identical with line truss column 5, but the specification of bus truss column 7 is slightly less than line truss column 5; Line beam 2 adopts braced beam; Bus girders 4 adopts braced beam; The chord member of line beam 2 and bus girders 4 all adopts common steel tube; Post, beam chord member joints adopt rigid flange, with bolts between soffit of girder bar and chord member; Ground terminal 1 is uniform section steel pipe ground terminal 1.
Constructure scheme of the present invention is after the integral hoisting of steel framework is in place, to carry out the pouring construction of post core concrete.
While adopting this constructure scheme, the segmentation transportation of truss of steel tube, on-site hoisting, stull connection etc. are all identical with original 750kV transformer station pure truss of steel tube, after difference is to adopt steel core concrete column, the specification of steel pipe diminishes, and hauled weight and lifting weight are all less than pure truss of steel tube.
After the whole hoisted in position of steel framework, adopt pumping-up method concreting.Pumping-up method can be disposable by the concrete lift-up in steel core concrete column to desired height, without vibration, can effectively avoid the defects such as steel pipe column inner concrete leakiness, segregation, guarantees concrete quality.Also can reduce process links, easy construction is quick.
While adopting pumping-up method concreting, need to steam vent and spout hole be set in capital appropriate location, in suspension column appropriate location, charging hole be set.
