Background technique
At present Indoor DC Field superstructure using beam column of steel structure added with the assembled scheme of purlin roof system, it is such
Scheme is more conventional, but disadvantage, it is also obvious that i.e. when column is also sharply increased away from purlin stress when increasing, purlin type selecting need to be from light-duty
It is wall thickness and larger-size heavy steel that light-gauge steel section, which increases, when column is away from further increase, even purlin size and wall
It is altogether unjustifiable and often is also difficult to meet the stress demand of roof structure greatly.
Since the Indoor DC Field device category of 1100kV voltage class is more, the equipment component scale of construction is larger, causes indoor
DC fields superstructure span demand is larger, simultaneously because need to consider that equipment poling and crane maintenance vehicle enter, leads to pillar
Spacing is also larger, and in this case, originally stress is larger for roof truss structure, it is more difficult to carry out structure design, but DC fields indoors
Part because poling need due to must extract structural column in the case where, roof truss branch tie distance by a column away from be expanded to two columns away from,
Mid span moment expands as original four times, and conventional roof truss structure scheme has been difficult to meet the design requirement of structure, needs to propose new
Roof truss support integrated technique scheme carry out problem solution.
Utility model content
The purpose of this utility model is that：In view of the problems of the existing technology, a kind of 1100kV Indoor DC Field is provided
Across the bearing bracket structure under casing roof truss, the span need that existing roof truss structure is not able to satisfy 1100KV Indoor DC Field are solved
The problem of wanting.
The purpose of this utility model is achieved through the following technical solutions：
A kind of 1100kV Indoor DC Field is across the bearing bracket structure under casing roof truss, which is characterized in that indoor direct current
Field is made of structural column and roof truss, and Indoor DC Field exists in conduit crossing canceling position structural column, the bearing bracket structure setting
Indoor DC Field is cancelled at the roof truss of structural column, and replaces the roof truss at this.
Further, the roof truss includes more across beam and two vertical bridges, and more are connected to two across beam side by side
Between vertical bridge, the upper end of structural column is connect with two vertical bridges, and indoors DC fields cancel knot to the bearing bracket structure setting
At the vertical bridge of structure column, and the vertical bridge at this is replaced, being connected in bearing bracket structure at this across beam.
Further, which is rest truss or rest frame.
Further, which is interconnected to constitute by plurality of rods part, and the rest truss constituted includes plane net
Lattice and vertical grid, the size of plane grid are 1.2m ~ 2.4m, and the size of vertical grid is 0.9 ~ 1.8m.
Further, the material of rod piece is steel construction tubing, angle steel, I-steel or H profile steel.
Further, the rod piece of bearing bracket structure is thicker than the rod piece of vertical bridge, the rod piece arrangement ratio of bearing bracket structure
Vertical bridge rod piece is arranged close.
Compared with prior art, the utility model can effectively solve Indoor DC Field steel superstructure since electrical casing is worn
The difficult design when conflict of position is more generated, in the case where guaranteeing the safety of structure of steel superstructure, so that casing cloth
Set it is more flexible, while for the optimization design of electric system arrangement convenience is provided.

Specific embodiment
The utility model is described in detail in the following with reference to the drawings and specific embodiments.
Embodiment
In power industry, conventional converter station is all made of the electrical arrangement form of outdoor direct field, and 1100kV is indoor straight
Flow field is then the electrical arrangement form for using large-span structure Indoor DC Field under 1100kV extra-high voltage rating conditions for the first time,
Belong to and initiate both at home and abroad, technical difficulty is larger.For structure overlength column caused by 1100KV Indoor DC Field poling away from lower roof truss
Difficult design, the utility model provide a kind of 1100kV Indoor DC Field across the bearing bracket structure under casing roof truss, such as Fig. 1
Shown in ~ Fig. 6.Indoor DC Field is made of structural column 3 and roof truss, and Indoor DC Field, should in conduit crossing canceling position structural column
The setting of bearing bracket structure 1 indoors cancel at the roof truss of structural column by DC fields, and replaces the roof truss at this.This structure is general
Property it is good, particularly with have on Indoor DC Field roof system overhang have equipment carry under lightning-arrest needle construction and roof system when, can preferably protect
Demonstrate,prove effective transmitting of the structural internal force at rest truss position under wind load and seismic loading, it is ensured that building is whole and attached
The safety of electric utility equipment.
Roof truss includes more across beam 4 and two vertical bridges 2, more across beam 4 be connected to side by side two vertical bridges 2 it
Between, the upper end of structural column 3 is connect with two vertical bridges 2, and indoors DC fields cancel structural column for the bearing bracket structure 1 setting
At vertical bridge 2, and the vertical bridge at this is replaced, being connected in bearing bracket structure 1 at this across beam 4.
The bearing bracket structure can use rest truss or rest frame.
The present embodiment provides a kind of specific structures of rest truss, are interconnected to constitute, are constituted by plurality of rods part
Rest truss includes plane grid（Referring to fig. 4）With vertical grid（Referring to Fig. 3）, the size of plane grid is 1.2m ~ 2.4m, is erected
It is 0.9 ~ 1.8m to the size of grid.
Steel construction tubing, angle steel, I-steel or H profile steel can be used in the material of rod piece.The material structure that the technical program uses
Part is steel construction tubing, is connect between tubing using relative inertia welding.
The rod piece of bearing bracket structure is thicker than the rod piece of vertical bridge, and the rod piece of bearing bracket structure is arranged than vertical bridge rod piece
That arranges is close.
When designing Indoor DC Field, the specific steps are：
(1) conduit crossing position is accurately positioned, it is determined whether collision is generated with structural column, if generating collision, further
Determining whether can be by adjusting column away from avoiding, if column is evaded away from can not adjust, final determine uses rest truss conduct
The Bracing Systems of local roof system；
（2）According to column away from feature, i.e., column away from order of magnitude and can classifying rationally number of segment, determine the reasonable of rest truss
Arrangement and composition, the plane grid size of rest truss preferentially select between 1.2m ~ 2.4m, and vertical size of mesh opening preferentially exists
It is selected between 0.9 ~ 1.8m, horizontal size should comprehensively consider with vertical dimension and be coordinated and be arranged in pairs or groups；
（3）According to the reasonable sizes of rest truss, establish the structural computational model of rest truss, and with main body knot
