Abstract
The utility model relates to a square steel tube column fireproofing structure, comprising a square steel tube column, wherein a polymer cement mortar binder layer is coated outside the square steel tube column, and an aerated sheet is adhered outside the binder layer. The square steel tube column fireproofing structure has the advantages of simple structure and strong practicability and can meet the requirements of building fire prevention code.
Description
Technical field
The utility model relates to steel building, particularly a kind of quadrate steel pipe column fire protection construction.
Background technology
Steel building has intensity height, light weight, plasticity and good toughness, high, the advantages such as convenience, good airproof performance of removing of industrialization degree, but its maximum shortcoming is that fire resistance is relatively poor.The main body that steel column carries as building, in case breaking out of fire, deformation is caved in rapidly when temperature rises to the critical-temperature of steel, steel will lose supporting capacity.Therefore, it is significant steel work to be carried out flameproof protection.
At present, steel structure fireproofing coats and mainly contains the spray fireproof paint and hang fire-proof board etc.This dual mode has carried out a large amount of utilizations in steel structure fireproofing, but also has a lot of defectives and problem, for example:
1, spray fireproof paint: material price is expensive, needs professional construction; Need carry out secondary decoration, and in follow-up construction, come off easily.
2, hang PLASTIC LAMINATED: material unit weight is big, increases the load-bearing of steel work; Increase construction cost and steel using amount; Construction technology is complicated, needs to install earlier keel, adopts anchorage styles such as bolt, tapping screw to fix, and has increased local conductivity of heat greatly, when fire, becomes weak part easily, is unfavorable for flameproof protection.
Therefore, existing steel structure fireproofing coating technology utilization exists weak point, and a kind of novel steel structure fireproofing of urgent need searching is constructed and replaced.
Summary of the invention
The task of the utility model provides a kind of quadrate steel pipe column fire protection construction, and it has solved the complicated problem of the not good and traditional fire prevention construction of steel column fireproof performance of prior art.
The technical solution of the utility model is following:
A kind of quadrate steel pipe column fire protection construction, it comprises quadrate steel pipe column, the outside of said quadrate steel pipe column is coated with the polymer cement mortar adhesive layer, is pasted with the aerating sheet material in the outside of this adhesive layer.
Said polymer cement mortar adhesive layer thickness is 1-20mm.
Said aerating sheet thickness is 10-100mm.
The said aerating sheet material batch fissure of displacement is up and down pasted.
The utility model makes it compared with prior art owing to adopted above technical scheme, and the quadrate steel pipe column fire protection construction of the utility model has simple in structure, practical advantage, can satisfy the requirement of building fire code.
Description of drawings
Fig. 1 is the structural representation of a kind of quadrate steel pipe column fire protection construction of the utility model.
Reference numeral:
1 is quadrate steel pipe column, and 2 is the polymer cement mortar adhesive layer, and 3 are the aerating sheet material.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is elaborated.
Referring to Fig. 1, the utility model provides a kind of quadrate steel pipe column fire protection construction, is coated with polymer cement mortar adhesive layer 2 in the outside of quadrate steel pipe column 1, is pasted with aerating sheet material 3 in the outside of this adhesive layer 2.The aerating sheet material batch fissure of displacement is up and down pasted.
Polymer cement mortar adhesive layer thickness is 1-20mm.The aerating sheet thickness is 10-100mm.
As shown in fig. 1, the structure that the utility model provides comprises quadrate steel pipe column 1, polymer cement mortar adhesive layer 2 and aerating sheet material 3, and the outer directly employing of steel column polymer cement mortar is criticized and scraped on the aerating sheet material, sticks on the steel column surface.Cement mortar thickness is 1-20mm, and the aerating sheet thickness is 10-100mm.Aerating sheet material main component is an inorganic coagulation material, itself is refractory product.
Polymer cement mortar is the dry powder that forms with material mixing such as cement, sand, Admixtures, has performances such as adhesion stress height, water-fast, heatproof, freeze-thawing resistant.
The aerating sheet material is to be raw material with cement, quartz sand, lime and gypsum, through operations such as foaming, batching, stirrings, and maintenance 10-12 hour and the goods processed under HTHP.Material itself has good insulated fire heat-proof quality.
Polymer water material-mud after dry powder and mortar added water and stir directly batch is scraped on the aerating sheet material, and the aerating sheet attaching that will be stained with mortar is on quadrate steel pipe column, and batch fissure of displacement is pasted up and down.
Aerating sheet material and polymer cement mortar are inorganic material to be formed, and itself has good fireproof performance.Through adopting supporting polymer cement mortar directly to protect coating, can satisfy the requirement of building fire code in the mode that paste on the steel column surface.
In sum, the quadrate steel pipe column fire protection construction of the utility model has simple in structure, practical advantage, can satisfy the requirement of building fire code.
Certainly; Those skilled in the art in the present technique field will be appreciated that; The foregoing description only is to be used for explaining the utility model; And be not with the qualification of doing the utility model, as long as in the connotation scope of the utility model, all will drop in the scope of the utility model claim the variation of the foregoing description, modification etc.
