Abstract
The utility model relates to a frame structure used for a 220kV or 500kV or 1000kV transformer station. The frame structure comprises an A-shaped framework column and a leading-out steel beam hinged to the A-shaped framework column. The leading-out steel beam is 1500-4000mm high and 1500-4000mm wide, and is a triangular or rectangular space truss beam. The space truss beam comprises two lower chords, one chord or two upper chords and a plurality of web members. The upper chords and the lower chords are made of angle steel or steel tubes, and the web members are made of the angle steels or the steel tubes. The A-shaped framework column is made of the steel tubes or solid steel tube concrete or is of a hollow steel tube concrete structure. The space truss beam is fixedly connected with a column head of the A-shaped framework column in a welding or bolt connection mode. By means of the optimized framework structure and an equipment support, the A-shaped framework column approximate to a cast steel joint and an independent approximate to oval framework column are used, so that steel is effectively saved, project cost is reduced, and the aim of saving resources is achieved.
Description
Technical field
The utility model relates to a kind of frame structures, relates in particular to a kind of frame structures for 220kV, 500kV or 1000kV transformer station.
Background technology
Because steel work has the characteristics such as intensity height, easy installation, easy recovery, transformer station in 220kV and above grade, framework and equipment supporter have generally adopted steel work, call in order to respond " amphitypy one is changed " (resource-conserving, environmentally friendly, industrialization), the various form of structure of transformer station are carried out positive optimization and innovation, framework and equipment supporter are continued to optimize, made form of structure more reasonable.Truss column is the important component part of substation framework in the AC Substation, mainly contains pylon post and A shape post, and A shape truss column generally adopts steel pipe, single solid steel pipe concrete and concrete-filled steel tubular hollow structure; The pylon post adopts steel angle structure, according to the loading characteristic of framework, has adopted nearly cast steel node A shape truss column and independent nearly oval truss column, thereby has effectively saved steel, has reduced construction costs, reaches the purpose that economizes on resources.
Summary of the invention
The utility model provides a kind of frame structures for 220kV, 500kV or 1000kV transformer station.
For achieving the above object, the technical solution adopted in the utility model is: a kind of for 220kV, the frame structures of 500kV or 1000kV transformer station, comprise A shape truss column and the outlet girder steel hinged with A shape truss column, the high 1500mm to 4000mm of outlet girder steel, wide 1500mm to 4000mm, the outlet girder steel is triangle or coffin girder truss, it is characterized in that: the space truss beam comprises two lower chords, one or two upper chords and some web members, top-bottom chord adopts angle steel or steel pipe, web member adopts angle steel or steel pipe, A shape truss column adopts steel pipe, single solid steel pipe concrete or concrete-filled steel tubular hollow structure, shell of column adopts flange to connect, and girder truss is fixedly connected on A shape truss column column cap by welding or bolt connecting mode; The steel pipe that described A shape truss column adopts can be straight seam welded steel pipe, ratio-frequency welded tube or seamless steel pipe, and the cross sectional shape of steel pipe is oval or circular; A shape truss column column cap adopts integrated casting joint or welding point.
By optimizing frame structures and equipment supporter, can adopt nearly cast steel node A shape truss column and independent nearly oval truss column, thereby effectively save steel, reduced construction costs, reach the purpose that economizes on resources.
