Description
Technical field
The invention belongs to building material technical field, specifically a kind of prefabricated board, particularly a kind of high-strength light
Concrete prefabricated board.
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, the reinforcement means of building structure has enlarging section, displacement concrete strengthening method, bonds steel-encasing strengthening
The methods such as method, affixing steel plate reinforcement method, stickup fibre reinforced plastics method for strengthening.Section-increased method and displacement coagulation local method are used
Concreting, although construction technology is simple, strong adaptability, but the wet trade time of site operation is long, it is impossible to meet the cycle short
Requirement.Bond the construction of steel-encasing strengthening method simple and convenient, but consumption steel material is big, and cost is higher, and should not be used in nothing
High temperature place in the case of protection.Affixing steel plate reinforcement rule is applied to being reinforced by curved or tensional element under dead load, no
Anti-seismic performance can be improved.
Therefore, it is necessary to work out a kind of method that can combine concrete strengthening method and steel method for strengthening advantage, reach
Both wet trade is reduced, shortens construction period, reduces steel consumption amount again, the effect of building structure aseismatic aspect of performance is improved.
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 high-strength light coagulation
Native prefabricated board, existing enough bearing capacitys and reduces foundation cost because lighter deadweight makes integrally-built weight saving.
In order to solve the above technical problems, the present invention provides a kind of high strength light concrete prefabricated board, including concrete
Layer, heat-insulation layer, strengthening layer and superficial layer, the superficial layer are arranged on the upper and lower surface of prefabricated board, between two superficial layers up and down
