Abstract
The utility model relates to a fire-resisting steel structure for a building. The fire-resisting steel structure is a steel structure which is encircled by steel plates, wherein hollow grooves are arranged inside the steel structure, and the hollow grooves are intercommunicated with each other; the upper end of the steel structure is provided with a ventilation hole; the quantity of the hollow grooves is 3 to 6; a hollow plastic pipe is arranged inside each hollow groove; two ends of each hollow plastic pipe are closed; and a valve are arranged on the steel structure. Through the technical scheme, liquid is injected inside the steel structure, and defects of the steel structure that the fire resistance is poor can be fundamentally solved; and meanwhile, the upper part of the steel structure is provided with a pipeline which is communicated with the air, so that the pressure inside and outside the steel structure is balanced.
Description
Technical field
The utility model discloses a kind of constructional materials, what be specifically related to is a kind of fire preventing steel structure for building.
Background technology
Steel work is made as main structure with steel, is one of main building construction types.The characteristics of steel are that intensity is high, large from heavy and light, rigidity, therefore be used for building large span and superelevation, extra-duty building is suitable especially; Material homogeneity and isotropism are good, belong to perfect elastic body, meet the basic assumption of common engineering mechanics most; Material plasticity, good toughness can have moderate finite deformation, can bear well dynamic loading; Construction period is short; Its industrialization degree is high, can carry out the high specialization production of mechanization degree; Machining accuracy is high, efficient is high, good leak tightness, therefore can be used for building gas tank, oil tank and transformer etc.Its shortcoming is that refractoriness and rotproofness are relatively poor.Be mainly used in the load-bearing skeleton between heavy goods vehicles, the mill construction that is subjected to dynamic load function, plate and shell structure, High-rise TV Tower and the longspan structures such as mast structure, bridge and warehouse, high level and super highrise building etc.Steel work should be studied high strength steel from now on, greatly improves its yield point strength; Want in addition the shaped steel of rolling new varieties, such as H shaped steel (claiming again wide width wing edge shaped steel) and T steel and profiled sheet etc. to adapt to the needs of longspan structure and super highrise building.It is to wrap outside fire proofing material or coat fire-retarding paint that the fireproofing technique of steel work uses maximum technology, although technique scheme can arrive the fireproof effect, cost is expensive, and construction is inconvenient, can not protect steel work from essence.
The utility model content
According to above-mentioned deficiency, the utility model discloses a kind of effectively fireproof steel work.
For achieving the above object, the technical solution of the utility model is a kind of fire preventing steel structure for building, and described fire preventing steel structure for building is the steel work that is surrounded by steel plate, and wherein steel work inside has hollow groove, UNICOM between the hollow groove.
Described steel work upper end is provided with air vent.
Described hollow groove is 3-6.
Described steel work can be rectangular steel tube or round steel pipe.
Be placed with hollow plastic pipe in the described hollow groove.
Described hollow plastic pipe closed at both ends.
Be mounted with valve on the described steel work.
After technique scheme, the beneficial effects of the utility model are by filling liquid in steel work, fundamentally solved determining of steel structure fireproofing poor performance, be provided with simultaneously the pipeline with air UNICOM on the top of steel work, can make the inside and outside pressure balance of steel work, the bottom of steel work is provided with valve, can change liquid simultaneously.
Description of drawings
Fig. 1 is the utility model overall structure schematic diagram.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further described.
By shown in Figure 1, the utility model fire preventing steel structure for building is the steel work 1 that is surrounded by steel plate, and wherein steel work 1 inside has hollow groove, UNICOM between the hollow groove; Steel work 1 upper end is provided with air vent 2; Hollow groove is 3; Steel work 1 can be rectangular steel tube or round steel pipe; Be placed with hollow plastic pipe 5 in the hollow groove; Hollow plastic pipe 5 closed at both ends; Be mounted with valve 4 on the inlet channel 3 on the steel work 1.
