Abstract
The utility model belongs to the field of design of building structures, and particularly relates to a tornado-resistance and flying-object-impact-prevention air inlet and exhaust window structure of a nuclear power station. A reinforced concrete cover is arranged on the outer side of a blind window of a ventilation chamber of a nuclear power station workshop, and a ventilation opening is formed in the direction, least likely to be impacted by a flying object, of the reinforced concrete cover. With the tornado-resistance and flying-object-impact-prevention air inlet and exhaust window structure of the nuclear power station, an air inlet and exhaust window can meet the requirement that in the safety requirement, an opening of a protective border needs to resist a tornado and prevent the flying object from impacting, meanwhile, the enough ventilation quantity can be obtained, and the design requirement for the ventilation is met.
Description
Technical field
The utility model belongs to the design of building structures field, and what be specifically related to the anti-cyclone of a kind of nuclear power station and missile roof bump advances the ventilation window structure.
Background technology
According to nuclear power plant's design safety regulation, for the relevant building of safety, the postulated initiating events of considering in its design basis comprises that aircraft impact, crash and cyclone fly the thing effect.And be positioned at the opening that protects the border, and belong to the weak link of relative thin, but will meet security regulations equally, must consider the harm of anti-cyclone and missile roof bump.
Therefore, when the design of protecting the border, can reduce the setting of opening as far as possible.But for traffic and the ventilation requirement of necessity, opening is inevitable.Usually, for door opening, the gate of the anti-cyclone of alternative special use and missile roof bump is arranged on the market, can satisfy the regulation requirement.For ventilating with advancing air outlet, form that then must the employing shutter, that could satisfy Design of ventilation advances the air draft requirement.
But the structure of shutter has determined it can not satisfy the regulation of anti-cyclone and missile roof bump in nuclear power plant's design safety.Therefore, need a kind of new structure way of invention, make the requirement that the air draft shutter can not only satisfy ventilation of advancing of ventilation opening, can also have the ability of anti-cyclone and missile roof bump, to realize purpose of design, guarantee the integrality on protection border.
The utility model content
The purpose of this utility model is the complexity at existing practical problem, and what a kind of simple and effective anti-cyclone and missile roof bump was provided advances the ventilation window structure design, can be used for the ventilating room of nuclear power station.
The technical solution of the utility model is as follows: the anti-cyclone of a kind of nuclear power station and missile roof bump advance the ventilation window structure, at steel concrete cover of shutter arranged outside of nuclear power station power house ventilation cell, the direction that is flown thing bump possibility minimum at described steel concrete cover has ventilation opening.
Further, the anti-cyclone of aforesaid nuclear power station and missile roof bump advance the ventilation window structure, wherein, the area coverage of described steel concrete cover is greater than the shutter area of ventilating room.
Further, the anti-cyclone of aforesaid nuclear power station and missile roof bump advance the ventilation window structure, wherein, the ventilation opening of described steel concrete cover is opened in the cover body bottom.
Further, the anti-cyclone of aforesaid nuclear power station and missile roof bump advance the ventilation window structure, wherein, the thickness of described steel concrete cover is 290-310mm.
The beneficial effects of the utility model are as follows: the advancing the ventilation window structure and can make into that ventilation window not only can satisfy the requirement that needs anti-cyclone and missile roof bump in the anti-cyclone of nuclear power station provided by the utility model and missile roof bump of the design safety regulation to(for) the opening on protection border, simultaneously, can obtain enough ventilations, satisfy the design requirement that ventilates.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in detail.
The ventilation window structure of advancing of the anti-cyclone of nuclear power station provided by the utility model and missile roof bump is steel concrete cover of shutter arranged outside at nuclear power station power house ventilation cell, and the direction that is flown thing bump possibility minimum at described steel concrete cover has ventilation opening.
Ventilating room is the building structure that the nuclear power station factory building is used for ventilation, and operated by rotary motion is at the top of factory building, and ventilating duct to ventilating room, advances air draft shutter ventilating room setting from the factory building internal communication.As shown in Figure 1 and Figure 2, the structure way of advancing ventilation window of anti-cyclone and missile roof bump is the steel concrete cover 3 of shutter 2 arranged outside at ventilating room 1 in the present embodiment, and the ventilation opening 4 of steel concrete cover is opened in the cover body bottom.The thickness of steel concrete cover is 290-310mm, general desirable 300mm, and the area coverage of steel concrete cover is greater than the shutter area of ventilating room.
Structure way of the present utility model mainly contains 3 innovations: at first, in the shutter arranged outside the crashproof cover of a reinforced concrete wall, be used for the destruction of anti-cyclone and missile roof bump; Secondly, the zone that crashproof cover covers will comprise and greater than the zone of window blind hatch, prevent from flying thing through the bump bounce-back, the harm opening; At last, when crashproof cover was connected with the body of wall at window blind hatch position, place, three faces surrounded, and protection flies the direction that the owner will originate, and the direction opening flying thing attack possibility minimum guarantees the requirement of ventilating.
Structure way of the present utility model not only simply effectively but also arrange ingeniously, can either satisfy the requirement that needs anti-cyclone and missile roof bump in the design safety regulation for the opening on protection border, simultaneously, can obtain good ventilation, satisfied the demand of Design of ventilation.
Obviously, those skilled in the art can carry out various changes and modification to the utility model and not break away from spirit and scope of the present utility model.Like this, if of the present utility model these are revised and modification belongs within the scope of the utility model claim and equivalent technology thereof, then the utility model also is intended to comprise these changes and modification interior.
