Background technology
The relevant energy consumption of building has accounted for 48.9% of social total energy consumption.The building relevant industries are in the total emission volumn of carbon dioxide, up to 70%.Toxic emission, dust pollution that the constructional materials production of high energy consumption, high pollution, the rubbish of building operations, sewage, dust pollution, constructional materials are produced, the power consumption that the huge large public building that particularly consumes energy impels sharply increases, and a large amount of particle of generating generation is " atmospheric haze " and the main contributor of severe environmental pollution that causes China.Wherein only building the greenhouse gas emissions that Energy in use is contributed, than the sum total of all exhaust emissions of the various vehicles, also have more 1.5 times, is " arch-criminal " who causes haze.
It is very far away that China developed country close with weather conditions compares gap, area of dwelling structure specific energy consumption is for they 3 times.Enclosure structure heat transfer coefficient: exterior wall is 4-5 times, and roof is 2.5-5.5 times, and exterior window is 1.5-2.5 times, and door and window air leakage is 3-6 times.
Under construction, the heat output of masonry wall structure is about 72%. heating air conditionings of building Energy in use and is about 20%, and door and window accounts for 10%.And the actual consumption size of heating air conditioning, the heat-insulating property of its architectural exterior-protecting construction is principal element.Body of wall is building and the long-pending the best part of atmosphere direct contact surface, and the building Energy in use accounts for the nearly 90% of building total energy consumption, so the building energy conservation heat preservation energy-saving of masonry wall structure system particularly is the most important thing of energy-saving and emission-reduction.
Summary of the invention
The present invention has overcome above-mentioned deficiency of the prior art, relates to a kind of energy-saving wall, the body of wall gross thickness under the condition of 240mm, thermal transmittance reaches 0.06 w/ (㎡ .k), thermal resistance is up to 16.52(㎡ K/W) world lead level.In conjunction with the relevant supporting technology of the inventor can realize without rubbish, without airborne dust, without sewage, noiselessness, energy-conservation, economize on water, save land, green garden type environmental protection construction that material-saving, environmental protection, industrialization are produced.
The energy saving building system of efficient, low-carbon (LC), environmental protection, environment that can the let us high pollution makes moderate progress.The harmony of promotion human and environment is compatible is purpose of the present invention.
The job practices of energy-saving wall of the present invention is: be 8:34:7:4:2.8:3:54:1-2:0.8-1.4:0.2-0.4:12-24:80-128 by metakaolin, konilite, calcium hydroxide, nano kaoline, crystal whisker of hexa potassium titanate, acicular wollastonite, high strength cement, wood fiber, mullite fiber, carbon fibers, water glass, water according to mass ratio, evenly pour mould 70% height part in stirrer for mixing and strike off; Steel mesh reinforcement is welded with to one of holddown groove attaching nut plate to face up and places by alignment pin, pouring remaining mix and blend material into mold again strikes off, after will the upper die male and female face covering downwards, be pressed, then extract alignment pin through 4000 tons of precompressed, 6000 tons press again, 8000 tons molded again; After moulding, put into steam-cured still through the side fascia of pruning airtight, through 18 hours, 1 MPa, 180 ℃ of autoclave curing post-dryings, become the inside and outside wallboard of energy-saving wall;
During assembling, by inner wall panel holddown groove and side fascia holddown groove, be placed on accordingly on assembling jig, high-strength carbon fiber plastics fixed component is aimed to inside and outside wall board top holddown groove and be inserted into the end, then high-strength carbon fiber plastics fixed component is inserted to wallboard bottom holddown groove to top; Successively high-strength carbon fiber plastics fixed component is all stuck with to the inside and outside wall board holddown groove;
The standby seamless die sleeve of slurry that drips is located, then, part and carbon fiber plastic fixed component in the body of wall chamber of having assembled are evenly sprayed to the 0.4-0.8mm air and decompose absorbing coating, after solidifying, the inside and outside wall board fixed is placed in the foam box mould, adopts composite modified polyurethane in the direct integrated type foaming moulding of body of wall inner chamber;
After whole body of wall inner chamber is enriched in foaming, open mould and take out body of wall, put into insulated building, place 60-70min in 35-40 ℃, make the foaming sclerous reaction complete.
