Abstract
The utility model discloses a fireproof steel structure used for construction, which comprises a steel body, wherein a reinforcing rib is arranged on the steel body, the steel body and the reinforcing rib are fixedly connected together to form an independent hollow cavity, and the surfaces of the steel body and the reinforcing rib are provided with fireproof layers. By the utility model, the energy consumption can be saved, the cost is lowered, the strength is enhanced, the thickness of the fireproof layers is uniform, the fireproof layers are not easy to crack and fall off, and the fireproof effect is enhanced.
Description
Technical field
The utility model relates to building material technical field, relates in particular to a kind of fire prevention steel work for building.
Background technology
At present, existing building all be unable to do without steel work, and the refractory ability of steel work is limited, traditional way is the surperficial sprayed fire proofing coating at steel work, the thickness that need spray repeatedly in the time will reaching the fire-protection rating of designing requirement to guarantee coating reaches flameproof effect, when spraying, because fall-out is more, and the thickness of coating manually is difficult to grasp when spraying, and along with the prolongation of using the age, coating chaps easily or obscission occurs, and this mode not only makes fire-protection rating be difficult to reach requirement, but also needing interim maintenance, fall-out causes the pollution to environment easily simultaneously; On the other hand, because the base material of fireproof paint uses heat insulating materials such as perlite, vermiculite, mineral wool more, its heat resistance is subjected to the limitation influence, and fire endurance is also undesirable, influences flameproof effect, thereby has influenced steel work applying in building trade.
The utility model content
The utility model provides at the deficiencies in the prior art that a kind of fireprotection layer thickness is even, fireproof performance good, and is free from environmental pollution, and need not maintenance, saves the fire prevention steel work for building in space.
For achieving the above object, the technical solution of the utility model is: fire prevention steel work for building, comprise the steel body, described steel body is provided with reinforcing rib, described steel body and described reinforcing rib are fixed together and form independently cavity, and the surface of described steel body and described reinforcing rib is provided with fireprotection layer.
As a kind of improvement, described fireprotection layer is the refractory fibre composite fire-proof blanket.
As further improvement, described refractory fibre composite fire-proof blanket is composited by alumina-silicate refractory fibre blanket and glass mat.
After having adopted technique scheme, the beneficial effect that the utility model is obtained is: by on the steel body reinforcing rib being set, can improve structural strength, and can make steel body and reinforcing rib form independently cavity by this structure, can wear various pipelines by this cavity, thereby make the space full use, save occupancy the building interior space; In addition, can protect steel work, play the effect of fire-proof high-temperature resistant, guarantee the fire savety of building by fireprotection layer.The utility model appearance is smooth, has improved intensity, and fireprotection layer thickness is even, is difficult for chapping and coming off, and has improved flameproof effect.
Description of drawings
Accompanying drawing is the structural representation of the utility model embodiment.
The specific embodiment
As shown in drawings, fire prevention steel work for building comprises steel body 1, the said steel body 1 of the utility model is an i iron, be fixed with reinforcing rib 2 on the described steel body 1, reinforcing rib 2 is arranged on the both sides of i iron, can improve the bulk strength of steel work by reinforcing rib 2.
Described steel body 1 is fixed together with reinforcing rib 2, and forms independently cavity 3, by this independently cavity 3 can wear various pipelines, thereby make the space full use, save occupancy to the building interior space, easy to use.
Surface at steel body 1 and described reinforcing rib 2 is provided with fireprotection layer 4, and fireprotection layer 4 can be fixedly installed on steel body 1 and the reinforcing rib 2 by linkages such as rivets.Wherein, described fireprotection layer 4 is refractory fibre composite fire-proof blankets, and described refractory fibre composite fire-proof blanket is composited by alumina-silicate refractory fibre blanket and glass mat.Refractory fibre composite fire-proof blanket light weight softness can change along with the change of shape of steel work, and no matter how much complicated the steel work shape is, only need fire blanket is rolled in the fire prevention position that steel structure body need carry out, just can be fixed, significantly reduce working strength of workers, and good looking appearance; Refractory fibre fire blanket thermal conductivity is low, unit weight is light, and heat resisting temperature can reach more than 900 ℃, can satisfy the requirement of different fire-protection ratings under corresponding conditions, and flameproof effect is good; And the refractory fibre fire blanket is soft, and vibration resistance, attraction can prevent the transmission of noise, help environmental protection; No fall-out is installed, just can not be occurred coming off once installing, phenomenon such as be full of cracks, long service life.
But adopt the utility model energy efficient, reduced cost, and appearance is smooth, has improved intensity, the fireprotection layer even thickness is difficult for chapping and coming off, and has improved flameproof effect.
