Abstract
The invention discloses a kind of fire-resistant light concrete prefabricated board, comprise layer of concrete, fire resistant infilling layer, insulation layer, keel shoe 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 fire resistant infilling layer, insulation layer, layer of concrete, insulation layer and fire resistant infilling layer successively; Described keel shoe 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 keel shoe is coated in described layer of concrete, and described insulation layer is made up of the coated polyurethane foam of screed.The present invention adds fire resistant infilling layer and fire-resistant keel layer in concrete prefabricated board, effectively can improve the fire resistance of precast plate, panel arranges noninflammability inorganic heat insulation material, when can avoid fire, flame and high-temperature gas have surface to enter into precast plate inside, lower the possibility of precast plate expanded by heating distortion; By the setting of multilayer materials, take into account the heat-insulating property of precast plate, fireproof performance and weight, reduce the foundation construction expense of building.
Description
Technical field
The invention belongs to building material technical field, specifically a kind of precast plate, particularly a kind of fire-resistant light concrete prefabricated board.
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, building fire protection requirement is more and more higher, fire resistance rating for constructional materials also improves thereupon, require that building not easily deforms or caves under case of fire, but traditional constructional materials industrial grade in this respect can not meet the demands often, therefore, being necessary to work out one can in conjunction with the fireproof prefabricated plate of concrete, reach and both reduced material cost, shorten construction period, lower distortion roasted by building risk at high temperature can be reduced again, improve the effect of building structure fire-resistance calamity 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 fire-resistant light concrete prefabricated board, existing enough supporting capacitys, the safe mass in house of can improving because having good fire resistance again.
In order to solve above technical problem, the invention provides a kind of fire-resistant light concrete prefabricated board, comprise layer of concrete, fire resistant infilling layer, insulation layer, keel shoe 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 fire resistant infilling layer, insulation layer, layer of concrete, insulation layer and fire resistant infilling layer successively; Described keel shoe 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 keel shoe is coated in described layer of concrete, 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 fire-resistant light concrete prefabricated board, and described concrete thickness accounts for the 1/3-1/2 of whole concrete prefabricated plate thickness.
Aforesaid fire-resistant light concrete prefabricated board, described surface course is that glass fiber mesh and carbon fiber screen cloth are composited.
Aforesaid fire-resistant light concrete prefabricated board, described layer of concrete is bubble concrete layer.
Aforesaid fire-resistant light concrete prefabricated board, 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.
