Embodiment Construction

[0047] Below in conjunction with accompanying drawing and embodiment the present invention will be described in further detail:

[0048] Reference attached Figure 4 , 5 , shown in 6, the present invention is used in substation GIS room's roof-through building structure to be based on dredging, and anti-blocking is supplemented, is the pre-set rain (snow) water organized drainage channel of the junction, in time the roof rain (snow) Water drains. The conventional flashing structure is cancelled, and a gap is set at the junction of the roof profiled steel plate and the roof-penetrating column. At the same time, a water collection and diversion groove 5 is set at the corresponding lower position, and an inverted V-shaped diverter plate is installed in the direction of the adjacent column. 3. The water collection and diversion groove 5 is located directly below the roof profiled steel plate, is arranged around the periphery of the roof piercing column 1, and is welded to the s...

Abstract

The invention discloses a through roof building construction for a GIS chamber of a transformer substation. A clearance is arranged at a coupling section of a roof profiled steel plate and a through roof upright column, a water catchment and diversion trench is arranged in a lower position corresponding to the clearance, an inverted V-shaped splitter plate is arranged in an inflow direction adjacent to the through roof upright column, a clearance is arranged at the coupling section and used as a drainage gallery for little rainwater, and the rainwater is collected by the lower water catchment and diversion trench and directly drained into a rain gutter. The invention adopts the scheme of giving priority to dredging and draining and taking plugging prevention as the auxiliary method, the water catchment and diversion trench is positioned below the roof profiled steel plate, through roof steel members are arranged all around, so that rain (snow) water in the weak region of the coupling section is ensured to be drained in time, and the purposes of construction simplification and safe and lasting waterproofing are achieved.

Description

【Technical field】 [0001] The invention belongs to the field of power transmission and transformation engineering, and relates to a roof-through building structure for a GIS room of a substation. 【Background technique】 [0002] The GIS room of the substation generally adopts a conventional steel structure factory building. In order to optimize the layout of the substation and save land, the hanging wire frame of the incoming and outgoing lines can be placed above the GIS room, that is, the design of the GIS room should consider the structural layout, component stress and New requirements for building construction. For the steel structure factory building, if the attached wire hanging function is considered, the steel frame column of the main structure of the factory building is generally extended upwards, the cantilever column is used to carry the wire hanging beam higher than the eaves, and the steel structure of the original building is used as the supporting structure of t...
