Compared to the existing steel-concrete shear wall mixed structure valve Room, the utility model has following beneficial to effect
Fruit：
(1) steel column three bread in the valve Room is enclosed using U-shaped fire wall arrangement, valve Room lateral dimension can be reduced, can either be met
Converter power transformer fire protection requirement, while it is (new using this practicality by taking certain ± 1100kV converter station valve hall as an example also to optimize floor space
Type valve Room structure scheme can reduce valve Room lateral dimension 2m, can reduce valve Room floor space 237m2)；Overcome existing skill
Art occupation of land is larger, and (ultra-high voltage converter station valve Room fire wall spacing is generally 10~15m at present, according to conventional T-type fireproof wall cloth
Scheme is set, then fire wall need to be completely or partially arranged in other than the steel column edge of a wing of the valve Room, consider that suspension column and steel column lifting need to be reserved
A part of space, and valve Room steel column section is often larger, causes the valve Room to be taken up an area larger), while being also unfavorable for lacking for electrical arrangement
Point；
(2) valve Room steel column and fire wall are disengaged using U-shaped fire wall and are arranged, steel roof truss both sides all with valve Room steel column phase
Even, Steel bent frame structure is formed, Steel bent frame structure system deformation in the valve Room is not restricted substantially by fire wall, and the utility model valve Room is whole
Deformation is based on being translatable, and valve Room rigidity is uniform, excellent earthquake resistance；And the mixed structure scheme in the existing valve Room, steel roof truss side
Be connected with valve Room steel column, the other side is positioned on fire wall, since fire wall anti-side rigidity is larger, cause valve Room overall deformation with
Based on torsion, the poor disadvantage of anti-seismic performance；
(3) the U-shaped fire wall height of the utility model, which need to only meet change of current change fire protection requirement, (to be generally 15m or so),
It is only calculated with fire wall expense, fire wall concrete works amount about 40% can be reduced；Overcome the prior art this body concrete use
Measuring big disadvantage, (the mixed structure scheme in the existing valve Room, since fire wall is effectively supported as steel roof truss, fire wall height need to be done
To roof truss lower edge (typically about 24~35m))；
(4) fire wall height can be largely reduced, U-shaped fire wall arrangement is also convenient for live masterplate and installs, steel construction
Lifting is not restricted by on-site concrete construction speed, is conducive to construction organization, is accelerated construction progress, and construction risk is reduced；Overcome
The construction of prior art reinforced concrete shear wall is complicated, and the duration is longer, steel structure hoisting is by on-site concrete project progress system
About (valve Room height is higher, span is larger, brings the construction difficult problems such as formwork erection, mass concrete continuous placing) the shortcomings that.
