Description

Explosion resistant structure peripheral protective expanded joint structure

Technical field

The utility model is related to the protection of armored concrete explosion resistant structure, more particularly to a kind of explosion resistant structure outside Go along with sb. to guard him expanded joint structure.

Background technology

Many process units are respectively provided with inflammable, explosive characteristic in oil refining and chemical plant, can take during to meet disaster Emergency measure, enough protections are provided for operating personnel and control device, and suppress disaster spreading, avoid that secondary disaster occurs It is required that the building for placing control system itself have to possess the ability for bearing destructive power caused by device explosion, it is desirable to do Into explosion resistant structure.

The current explosion resistant structure designed both at home and abroad is mostly reinforced concrete frame shear wall structure, and according to《Concrete Code for structural design》GB50010, to the cast-in-place shear wall structure in concrete steel building, it need to be set when length is more than 45m Expansion joint is put, to reduce structure because temperature, wetness action are to adverse effect caused by structure.According to existing《Building aseismicity is set Count specification》GB50011、《Technical specification for concrete structures of high-rise building》JGJ3 requirement, to this height of explosion resistant structure one As be no more than 15m cast-in-place shear wall structure, expansion joint width is not less than 100mm.

To in general Industrial and Civil Engineering, at the expansion joint of architecture enclosing shield, general set both meets to build Building structure plays the building expansion gap device of decoration function using function and can, and the device is mainly (steel plate, stainless by shape Steel plate, aluminium alloy plate) " pedestal ", metal or rubber " cover plate " and the metal " slide bar " of connection pedestal and cover plate composition, but type The intensity of material only adapts to the requirement of routine building thing load, typically using swollen between shape pedestal and main body load-carrying members The connected modes such as anchor bolt.

For explosion resistant structure, the explosion wave load to be born is far longer than routine building thing load, due to It uses the particularity of function, in order to stop that explosion wave is propagated by any hole, gap, so as to in explosion resistant structure Personnel, injury caused by equipment, explosion resistant structure limits the use at the expansion joint in explosion resistant structure,《Petrochemical industry controls Room anti-explosion design specification》GB50779 is even more to expressly provide, explosion resistant structure must not set expansion joint.

With the present situation that the explosion resistant structure scale such as oil plant control room the more is done the more big, the length of explosion resistant structure breaks through 《Code for design of concrete structures》The situation that GB50010 does not set the maximum allowable length in expansion joint is more and more, and conventional non-antiknock Building expanded joint structure is under Blast Loads, the deficiency of its intensity, will be unable to ensure it to close at building gap Envelope acts on.

For explosion resistant structure, when building overlength, it has to when setting expansion joint, it is usually required mainly for solution is periphery Protection structure, include the sealing problem of the expanded joint structure of exterior wall and roofing.

Utility model content

In order to solve building external labeling type expansion gap device structural strength deficiency existing for prior art, can not meet to explode The sealing function of explosion vention is required under load action, so as to influence the technical problems such as explosion resistant structure safe handling, this Utility model provides a kind of explosion resistant structure peripheral protective expanded joint structure, and the expanded joint structure becomes in adaptive temperature, humidity etc. In the case of change while building deformation requirement, the Security Function Requirements of explosion resistant structure are also disclosure satisfy that.

Explosion resistant structure peripheral protective expanded joint structure provided by the utility model by expansion joint, peripheral backplate and can mainly be stretched Contracting profile plate forms；Expansion joint both sides are peripheral backplate, and scalable profile plate is by the telescopic section in the middle part of scalable profile plate With the flat plate section composition positioned at scalable profile plate both ends, flat plate section is arranged at the both sides of telescopic section, scalable profile plate both ends Flat plate section be embedded to respectively in the peripheral backplate of expansion joint both sides, telescopic section in the middle part of scalable profile plate is kept off on expansion joint.

Described scalable profile plate is made up of sheet metal, and described telescopic section cross sectional shape is W fold-line-shapeds or half arc Shape, the rectangular dentation of described flat plate section, naturally it is also possible to be processed into other shapes as needed.

The utility model can be used at explosion resistant structure expansion joint in the peripheral protective of wall and roofing, the metal mold of flush type Material plate can live the gap shielding at the expansion joint set by all peripheral structures, avoid shock wave into interior of building Risk；Shape plate construction possesses certain dilatation function in itself, it is ensured that wall caused by temperature, humidity change With free dilatation during roof boarding overlength.In a word, the utility model solves overlength explosion resistant structure and sets expansion joint Problem, positive pressure of shock wave can not be stopped caused by fundamentally avoiding buildings in general exterior wall, roofing insertion expansion joint way The drawbacks of, configuration is simple, and cost is cheap, easy to implement, and apply reduces difficulty of construction in overlength explosion resistant structure engineering, contracting The short duration of a project, efficiency of construction is improved, while ensure that the realization of explosion resistant structure Security Function Requirements.
