The invention discloses a kind of high strength light concrete precast plate, comprise layer of concrete, insulation layer, strengthening layer and surface course, described surface course is arranged on the upper and lower surface of precast plate, between upper and lower two surface courses, be from bottom to top provided with insulation layer, layer of concrete, strengthening layer, layer of concrete and insulation layer successively; Described strengthening layer comprises the grid framework be made up of carbon fiber guide rod and the wire gauze covering described grid-like framework is formed, and described insulation layer is made up of the coated polyurethane foam of screed.The present invention can formulate size according to designing requirement, and sheet material shape can adapt to different requirement.Plant produced and prefabricated can be realized, be transported to reinforcing scene and directly assemble, convenient and swift, shorten construction period.Improve the performance of new-old concrete bed boundary deformation.Prefabricated panels energy-absorbing effect is good, can improve the anti-seismic performance of structural element, strengthens the intensity of precast plate.
Description
Technical field
The invention belongs to building material technical field, specifically a kind of precast plate, particularly a kind of high strength light concrete precast plate.
Background technology
The design life of general concrete structure is 50 years.When building structure reaches design life, structural performance does not significantly reduce, and still can to continue normal use after reinforcing, consider to remove reconstructed cost larger, the way of structural strengthening can be adopted, structure is keeped in repair, reinforce, ensure that its bearing capacity meets code requirement.
At present, the reinforcement means of building structure has enlarging section, displacement concrete strengthening method, bonding steel-encasing strengthening method, affixing steel plate reinforcement method, pastes the methods such as fibre reinforced plastics reinforcing method.Section-increased method and displacement coagulation local method all adopt concreting, although construction technology is simple, strong adaptability, the wet trade time of site operation is long, can not meet cycle short requirement.The construction of bonding steel-encasing strengthening method is simple and convenient, but consumption steel material is large, and cost is higher, and should not be used for the high temperature place in unshielded situation.Affixing steel plate reinforcement rule be applicable under dead load by reinforcing that is curved or tensional element, can not anti-seismic performance be improved.
Therefore, be necessary to work out a kind of in conjunction with the method for concrete strengthening method and steel reinforcing method advantage, can reaching and both reduced wet trade, shorten construction period, reduce steel consumption amount again, improve the effect of building structure aseismatic aspect of performance.
Summary of the invention
Technical problem to be solved by this invention is, overcomes the shortcoming of prior art, provides a kind of high strength light concrete precast plate, existing enough supporting capacitys, reduces foundation cost because lighter deadweight makes integrally-built weight saving again.
In order to solve above technical problem, the invention provides a kind of high strength light concrete precast plate, comprise layer of concrete, insulation layer, strengthening layer and surface course, described surface course is arranged on the upper and lower surface of precast plate, between upper and lower two surface courses, be from bottom to top provided with insulation layer, layer of concrete, strengthening layer, layer of concrete and insulation layer successively; Described strengthening layer comprises the grid framework be made up of carbon fiber guide rod and the wire gauze covering described grid-like framework is formed, and described insulation layer is made up of the coated polyurethane foam of screed.
The technical scheme that the present invention limits further is: aforesaid high strength light concrete precast plate, and described strengthening layer thickness accounts for the 1/6-1/5 of whole concrete prefabricated plate thickness.
Aforesaid high strength light concrete precast plate, described surface course is glass fiber mesh.
Aforesaid high strength light concrete precast plate, described layer of concrete is bubble concrete layer.
Aforesaid high strength light concrete precast plate, described layer of concrete is counted by weight and is comprised following component: portland cement 20 ~ 40 parts, coal dust ash 6 ~ 9 parts, 2 ~ 8 parts, calcium oxide, 1 ~ 4 part, gelatine powder, neopelex 3 ~ 4 parts, shitosan 1 ~ 5 part, sodium aluminate 2 ~ 6 parts, anhydrous sodium sulfate 3 ~ 7 parts, lithium carbonate 1 ~ 6 part, Hydroxypropyl methylcellulose 2 ~ 4 parts, polypropylene fibre 3 ~ 8 parts, sepiolite 2 ~ 5 parts, water glass 6 ~ 8 parts, diethylenetriamines 1 ~ 6 part, haloflex 2 ~ 5 parts, anion surfactant type blowing agent 3 ~ 6 parts, 2 ~ 7 parts, lecithin, triethanolamine 2 ~ 5 parts, polycarboxylate 1 ~ 3 part.
