Abstract
The utility model provides a fireproof steel structure for a building with low cost and good fire resistance. The fireproof steel structure comprises a fire resistant plate box and an I-shaped steel body arranged in the fire resistant plate box. The two sides of the I-shaped steel body are provided with reinforced ribs. Separation nets are arranged among the fire resistant plate box and the upper and lower end surfaces of the I-shaped steel body. Light fire resistant materials are filled in the fire resistant plate box. As a plenty of light fire resistant materials are filled in the fire resistant plate box, the fireproof steel structure is good in fireproof performance and low in cost. And the two sides of the I-shaped steel body are provided with the reinforced ribs, so that the fireproof steel structure for the building is good in firmness and difficult to deform and collapse.
Description
Technical field
The utility model relates to a kind of steel work, especially a kind of building fire protection steel work.
Background technology
At present, building trade be unable to do without steel work, and the refractory ability of steel work is limited, has restricted the development of steel work to a certain extent.Under the high temperature action of the scene of a fire, plastic strain will soon appear in exposed steel work, loses efficacy, and then causes total collapse, causes serious casualty accident and economic loss.
The utility model content
The utility model provides the building fire protection that a kind of cost is low, fire resistance is good steel work.
Realize the building fire protection steel work of the utility model purpose; Comprise refractory slab case and the i iron main body that is positioned at said refractory slab case; Said i iron main body both sides are provided with reinforcing rib; Be provided with separate mesh between the upper and lower end face of said i iron body and the said refractory slab case, be filled with lightweight refracrory in the said refractory slab case.
Said lightweight refracrory is that foam mixes earth.
The beneficial effect of the utility model is following:
The building fire protection steel work of the utility model, owing to filled a large amount of lightweight refracrories, fire resistance is good in the refractory slab case, and cost is low, and i iron body both sides are provided with reinforcing rib, and fastness is not good, and is yielding, cave in.
Description of drawings
Fig. 1 is the structural representation of the utility model building fire protection steel work.
The specific embodiment
The embodiment of the utility model is following:
As shown in Figure 1; The building fire protection steel work of the utility model; Comprise refractory slab case 2 and the i iron main body 1 that is positioned at said refractory slab case 2; Said i iron main body 1 both sides are provided with reinforcing rib 5, are provided with separate mesh 4 between the upper and lower end face of said i iron body 1 and the said refractory slab case 2, are filled with lightweight refracrory 3 in the said refractory slab case 2.
Said lightweight refracrory 3 mixes earth for foam.
The building fire protection steel work of the utility model, owing to filled a large amount of lightweight refracrory 3, fire resistance is good in refractory slab case 2, and cost is low, and i iron body 1 both sides are provided with reinforcing rib 5, and fastness is not good, and is yielding, cave in.
Embodiment recited above describes the preferred implementation of the utility model; Be not that scope to the utility model limits; Design under the spiritual prerequisite not breaking away from the utility model; Various distortion and improvement that the common engineers and technicians in this area make the utility model technical scheme all should fall in the protection domain that claims of the utility model confirm.
Claims (2)
1. building fire protection steel work; Comprise refractory slab case and the i iron main body that is positioned at said refractory slab case; It is characterized in that: said i iron main body both sides are provided with reinforcing rib; Be provided with separate mesh between the upper and lower end face of said i iron body and the said refractory slab case, be filled with lightweight refracrory in the said refractory slab case.
2. building fire protection steel work according to claim 1 is characterized in that: said lightweight refracrory is that foam mixes earth.
