Abstract
The utility model discloses a transformer substation 500kV framework. Free-standing lattice columns with high strength are arranged in a longitudinal middle line of the framework, and A-shaped columns are arranged on two sides of the free-standing lattice columns in longitudinal lines; and supports among vertical beam columns are arranged on the top ends of the elevated columns and are connected with top booms of truss girders. In the utility model adopting the technical scheme, by arranging the free-standing lattice columns in the longitudinal middle part of the combined framework and simultaneously eliminating the arrangement of end supports on two ends, the purpose of separating temperature sections for an ultralong framework is achieved; and moreover, steel consumption is reduced, floor area of the framework is reduced, and good economic and social benefits are obtained.
Description
Technical field
The utility model relates to a kind of new structure arrangement form that adopts at 500KV framework in the transformer station.
Background technology
At present, rapid economy development significantly rises to the demand in soil, soil particularly cultivated land resource is most valuable, adds that outward " amphitypy one change " work of transformer station is promoted in the whole nation, and economizing on resources, reduce floor space has effectively become rigid index in the transformer substation construction.
The 500kv framework mostly is multispan overlength associating framework in the transformer station at present, will consider the influence of temperature action effect when length exceeds 150m.Present conventional way has two kinds: a kind of is temperature joint (establishing two groups of herringbone groups) to be set to reduce the influence of thermal stresses at the middle part.This scheme can reduce temperature section length, effectively reduces the stress that is produced by variations in temperature, but because of being provided with temperature joint, has increased lineup's word post, and it is big that steel using amount and floor space all become.Another kind of way is less if stride number, and exceeding standard, to limit length few, and the centre is not provided with temperature joint, the end support is set with lateral force resistance at vertical two ends, but this way has also increased floor space.
Summary of the invention
The purpose of this utility model provides a kind of 500kV of transformer station framework that reduces floor space, saves steel using amount.
For achieving the above object, the utility model is by the following technical solutions:
The utility model is arranged the big self-supporting lattice column of intensity in vertical middle column of framework, and the longitudinal row in described self-supporting lattice column both sides is provided with A type herringbone column; And set up between beam column to support at overhead capital end and link to each other with the girder truss upper chord.
Described A type herringbone column is made up of round steel pipe.
The utility model of technical scheme in the employing, by being set at associating framework longitudinal middle part, the vertical simultaneously cancellation of self-supporting lattice column two ends end support arranges, thereby realized the overlength framework is carried out the purpose that temperature section is separated, save steel using amount, reduced the floor space of framework, brought into play good economic and social benefit.
Description of drawings
Fig. 1 is a framework axonometric drawing of the present utility model.
Fig. 2 is a framework front view in the utility model.
Fig. 3 is a framework lateral view in the utility model.
The specific embodiment
As Fig. 1, Fig. 2, shown in Figure 3, framework of the present utility model laterally has three row, arranges the big self-supporting lattice column 1 of intensity in vertical middle column of framework, and the longitudinal row in self-supporting lattice column 1 both sides is provided with A type herringbone column 2; And set up between beam column at overhead capital end and to support 3 and link to each other with girder truss upper chord 4.
Above-mentioned A type herringbone column 2 is made up of round steel pipe.
Principle of the present utility model is: the new construction arrangement form truck transom that the utility model proposed adopts is just putting the triangular section girder truss, and at the bigger self-supporting lattice column of the vertical intermediate arrangement rigidity of framework, all the other framework posts all adopt A type herringbone column, the longitudinal end herringbone column is not provided with the end support, allow the temperature dilatation be that freely stretch at middle mind-set two ends with the lattice column place, thereby reduce temperature section length, just can consider the influence of temperature action effect, effectively reduce the internal force of partial component, and then reduce the partial component section, save rolled steel dosage, the also corresponding minimizing of floor space.Simultaneously, the conventional high trestle of arranging of framework is a cantilever member, and big moment of flexure is born in overhead column bottom, and rod member type selecting cross section is bigger.This programme is set up to support between beam column at overhead capital end and is linked to each other with the girder truss upper chord, makes the framework post form the tension and compression member to reduce high trestle and lower post section in fore-and-aft plane, saves rolled steel dosage.
Claims (2)
1. the 500kV of transformer station framework is characterized in that: the vertical middle column at framework is arranged the big self-supporting lattice column (1) of intensity, and the longitudinal row in described self-supporting lattice column (1) both sides is provided with A type herringbone column (2); And set up between beam column at overhead capital end and to support (3) and link to each other with girder truss upper chord (4).
