Description
Technical field
The invention belongs to the component technology field of fixed buildings.
Background technology
The light body of roof panel, insulation, high strength are the topmost striving directions in this field, and up to the present, comparatively Cheng Shu product has " space plate " and FC composite plate.Wherein the former surface is a conventional cement mortar, and the centre is a foam cement, and the latter is the benzene plate that foams with FC (Cement fibre) plate holder that forms commodity.Both relatively, " space plate " weight is big, heat-insulating property is relatively poor, intensity is higher than the FC composite plate, though and the FC composite plate has heat-insulating property preferably, intensity is low, inflammable, fire safety problem is outstanding.
Summary of the invention
The objective of the invention is to create useful performances such as a kind of light body that has both existing roof panel, insulation, intensity height, overcome these strong those weak contradictions on the existing roof panel performance.
The scheme of roof panel of the present invention comprises:
1, condense in together upper and lower surface layer and the sandwich material layer between the surface layer;
2, wherein upper and lower two-layer is to mix the fiber-reinforced polymer modified high-strength haydite concrete that forms by cement, flyash, haydite, polymer emulsion, organic short fiber, high efficiency water reducing agent, waterproof agent, blowing agent, exciting agent, water, and wherein each raw material weight umber ratio is; Cement 1, flyash 0.1-1, haydite 1-3, medium sand 0-1.5, polymer emulsion 0.01-0.35, organic short fiber 0.001-0.005, high efficiency water reducing agent 0.005-0.015, waterproof agent 0.001-0.05, blowing agent 0.001-0.05, exciting agent 0.005-0.025, water 0.35-0.5;
3, the therebetween heartwood bed of material is a cement, flyash, the EPS particle, expanded perlite, haydite, polymer emulsion, interfacial agents, high efficiency water reducing agent, hydrophober, blowing agent, exciting agent, water mixes the polymer modification foaming super-light aggregate concrete that forms, and wherein each raw material weight umber ratio is: cement 1, flyash 0.1-1, EPS particle 0.03-0.13, expanded perlite 0.02-0.12, haydite 0.1-2, polymer emulsion 0.01-0.35, interfacial agents 0.01-0.1, high efficiency water reducing agent 0.005-0.015, hydrophober 0.001-0.01, blowing agent 0.001-0.08, exciting agent 0.005-0.025, water 0.35-0.5;
4, the bar construction skeleton is arranged in the intermediate layer.
More than be basic scheme of the present invention.
The present invention can also have fiberglass gridding cloth or gauze wire cloth reinforcing material in surface layer, with the intensity of further raising surface layer.
The method for production of roof panel of the present invention is; The upper and lower layer material that will mix earlier is poured in the prefabricated mould as surface layer down, and sneaks into the alkali-resistant glass fibre grid cloth or gauze wire cloth is a reinforcing material.With the cast of the therebetween heartwood material that mixes in the layer below, be equipped with cage of reinforcement again, and then the cast upper layer, and be equipped with the alkali-resistant glass fibre grid cloth or gauze wire cloth is a reinforcing material.Whole pouring into an integrated entity, precuring, the demoulding, maintenance through the concrete component of routine promptly get roof panel of the present invention.
Good effect of the present invention is: upper and lower surface layer and middle sandwich insulation layer condense in together, bulk strength height, the light aggregate concrete of surface layer have outstanding lightweight, high-strength, cracking resistance, water proof anti-seepage, fire prevention, corrosion resistant advantage and more significantly insulation, heat-proof quality.The super-light aggregate concrete of middle sandwich of layers has outstanding insulation, heat-proof quality and obviously is better than the intensity of same type of material, and water proof anti-seepage, cracking resistance, fire prevention, decay resistance.Surface layer of the present invention and sandwich of layers are condensed in together, have complementary advantages, promptly form roof panel with remarkable combination property.After testing, surface layer light aggregate concrete unit weight 900-1450kg/m
3, intensity 8-30Mpa, heat conduction 0.2-0.35W/m k; The super-light aggregate concrete unit weight 200-300kg/m of sandwich of layers
3, intensity 0.4-1.0Mpa, heat conduction 0.05-0.075W/mk.
The specific embodiment
1, preparation surface layer fiber-reinforced polymer modified high-strength haydite concrete, raw materials used is cement 100Kg, flyash 42Kg, haydite 263Kg, medium sand 75Kg, polyacrylate polymer emulsion 20Kg (also can use the ethene-vinyl acetate copolymerized polymer latex or the cinepazid polymer emulsion of identical weight), PP organic short fiber 0.1-0.5Kg, the high efficiency water reducing agent 0.5-1.5Kg of length 5-15mm, waterproof agent 0.1-5Kg, blowing agent 0.1-5Kg, exciting agent 10Kg, water 35-50Kg;
