Abstract
The utility model discloses a construction fire-proof steel structure which comprises an I-shaped steel main body. The utility model is characterized in that the two sides of the I-shaped steel main body are provided with reinforced ribs, a bottom mesh is covered outside the main body and the reinforced ribs, and the outer of the bottom mesh is covered with a reinforced mesh of which the outer is a fire-proof paint layer. The construction fire-proof steel structure is capable of decreasing the costs, further the inner space of the structure is penetrating provided with miscellaneous pipe lines, and the space is saved. The appearance of the utility model is smooth, the surface intensity is high which can be scratched and painted with putty directly, and thereby the first finishing effect is reached.
Description
Technical field
The utility model relates to constructional materials, refers to a kind of construction steel structure especially, as beam, and post etc.
Background technology
As everyone knows, modern building is to be unable to do without steel work, and the refractory ability of steel work is limited, must apply fireproof paint at the steel work external surface, also to decorate (as outsourcing PLASTIC LAMINATED, gypsum plank etc.) afterwards and could make exterior decoration, make cost higher, uneconomical.
Summary of the invention
The utility model aims to provide a kind of building fire protection steel work, uses this building fire protection steel work, the cost that can reduce cost, and the inside configuration space can wear various pipelines simultaneously, saves the space.
Technical solution adopted in the utility model is as follows: a kind of building fire protection steel work, comprise the i iron main body, it is characterized in that being provided with reinforcing rib, be coated with one deck spacer screen in main body and reinforcing rib thereof in i iron main body both sides, spacer screen is coated with reinforcing mat, and reinforcing mat is outward one deck fireproof paint layer.
The mesh of spacer screen is φ 4mm.
Reinforcing mat is expanded metal lath or alkali-proof glass silk cloth, and its mesh is 12mm * 20mm.
The effect that reinforcing rib is set in the i iron both sides in the utility model is in order to set off and fixing spacer screen; improve structural strength simultaneously; spacer screen is that the coating that sets off the bottom is used; the outer reinforcing mat of spacer screen plays the increase coating adhesion; prevent its cracking or the effect that comes off; outermost dope layer can protect steel work to play the effect of fire-proof high-temperature resistant, guarantees the fire savety of building.
Adopted this construction steel structure of the present utility model, engineering cost is significantly reduced, the i iron both sides can be for wearing various pipelines by the space that reinforcing rib crossed simultaneously, make the utilization in space more become reasonable, can save the occupancy to the building interior space, appearance of the present utility model is smooth, the surface strength height, directly blade coating putty reaches finishing effect just.Below in conjunction with accompanying drawing the utility model is described in further detail.
