Background technology
The design life of general concrete structure is 50 years.It is structural when building structure reaches design life
Can not be greatly reduced, it is reinforced after still be able to continue what is normally used, it is considered to it is larger to remove reconstructed cost, can use structure
The method of reinforcing, is repaired to structure, is reinforced, it is ensured that its bearing capacity meets code requirement.
At present, building fire protection requirement more and more higher, the fire resistance rating for construction material is also improved therewith, it is desirable to built
Thing is not susceptible to deform or caved under case of fire, but the industrial grade of traditional construction material in this respect is often not
Can meet require, therefore, it is necessary to work out one kind can combine the fireproof prefabricated plate of concrete, reach both reduce material into
This, shortens construction period, and the risk that building roasts lower deformation in high temperature can be reduced again, improves the anti-fire performance side of building structure
The effect in face.
The content of the invention
The technical problems to be solved by the invention are to overcome the shortcoming of prior art there is provided a kind of fire-resistant light concrete
Prefabricated board, existing enough bearing capacitys and because the safe mass in house can be improved with preferable fire resistance.
In order to solve the above technical problems, a kind of fire-resistant light concrete prefabricated board of present invention offer, including concrete layer,
Fire resistant infilling layer, heat-insulation layer, keel shoe and superficial layer, the superficial layer are arranged on the upper and lower surface of prefabricated board, in two tables up and down
Fire resistant infilling layer, heat-insulation layer, concrete layer, heat-insulation layer and fire resistant infilling layer are sequentially provided between surface layer；The dragon
Skeleton strengthening layer includes the grid framework being made up of carbon fiber guide rod and the woven wire for being covered in the grid-like framework and constituted,
The keel shoe is coated in the concrete layer, and the heat-insulation layer is made up of screed cladding polyurethane foam.
The technical scheme that further limits of the present invention is：Foregoing fire-resistant light concrete prefabricated board, the Concrete Thick
Degree accounts for the 1/3-1/2 of whole concrete prefabricated plate thickness.
Foregoing fire-resistant light concrete prefabricated board, the superficial layer be glass fiber mesh and carbon fiber screen cloth it is compound and
Into.
