Building block of the present invention is every M under the identical prerequisite of price 2Building area can reduce by 80 yuan/M of cost 2, effective area increases about 5%, and the duration shifts to an earlier date 30%, has reduced labour intensity.
Heat preservation principle:
Heat preservation and soundproof building block of the present invention is to utilize the minimum principle of air coefficient of thermal conductivity to change by the type body structure, require to determine materials for wall and width according to the weather conditions of each department, building structure, and change partition grooves number and width wherein realized adding insulation layer and the purpose that reaches heat preservation energy-saving.The wide thermal resistance value of insulation blocks 240mm of the present invention: load-bearing material R=1.29m 2K/w, light material R=1.44m 2K/w; The thermal resistance value that 300mm is wide: load-bearing material R=1.5m 2K/w, light material R=1.71m 2K/w; The thermal resistance value that 360mm is thick: load-bearing material R=1.85m 2K/w, light material R=2.1m 2K/w; The thermal resistance value that 420mm is thick: load-bearing material R=2.24m 2K/w; Below then by Dalian University of Technology's vibration and strength test center, building engineering quality supervision verification test center, Shandong Province and Liaoning Province's workmanship inspection center test proof.
By contrast, U.S.'s building block 390 * 190 * 190, density is 190mm, then thermal resistance value R=0.12m 2K/w; 240mm is wide in the clay building block, R=0.275m 2K/w, the present invention have then differed several times with it, can add the insulation requirement that insulation layer can reach each department.As build energy-conservation 65% dwelling house, require K=0.65w/m 2K, 300mm is wide adds the thick polyphenyl plate of 60mm with other building block need for light body structure, and wide with building block 240mm of the present invention, can satisfy K=1/1.44+0.15=0.628w/m 2K is less than 0.65w/m 2K satisfies energy-conservation 65% requirement.
Building block of the present invention has a great difference with clay building block of the prior art and other building block on brick-building art, at first the bonding of building block and building block is rigidity, there is not grey notch portion, thorough like this clay building block and insurmountable stressed crackle of other building block and the distortion crack problem of having solved.The formation (is example with the clay building block) of its stressed crackle and distortion crackle: size 240 * 115 * 53, the ash mouth is 8-12mm, quite the thickness 20% of clay building block; And the composition of mortar is different again, very fast because of mechanized construction speed when building by laying bricks or stones, but mortar partly is soft, thick as the suitable 50 floor building block of one deck chamber Senior Three rice, as each layer ash mouthful compressive deformation 0.1mm, then total deflection is 5mm, when having broken collar tie beam after sinking after a while, just show the slit, Here it is stressed crackle; In addition, the coefficient of thermal expansion and contraction of mortar is different with clay building block and other building block again, under the effect of temperature, because the coefficient of thermal expansion and contraction difference then is out of shape different, stress stack has just produced crackle at a certain vulnerable area, as building block in addition the internal stress when the moulding also vary with temperature simultaneously and discharge.And building block of the present invention is again that rigidity is bonding, so there is not stressed crack problem because there is not the ash mouth; Moreover the mortar composition of ash mouth is the same with building block aggregate composition, there is not the different reaction of coefficient of thermal expansion and contraction yet, and building block has been eliminated the moulding internal stress automatically by partition grooves, the small moulding variation of process behind shaping and demoulding, can after building a wall, not reflect again yet, this point is the last revolution of architectural history, has solved insurmountable illness over thousand.
Insulation blocks of the present invention is in that to add the tolerance that has just changed general building block man-hour too big, and homogeneous is the idea of mud, the making tolerance of insulation blocks is in ± 0.20mm, therefore as long as do by working specification, this not only expensive operation of not only taking a lot of work but also requiring great effort of plastering is removed on the wall two sides from, can directly enter into the internal and external ornament stage, can reduce construction cost 10% with regard to this, save labour 30%, in advance the duration 30% more than.
Processing: the building structure according to each department requires (as load-bearing or non-bearing, several floor heights, the requirement of building design and construction standard) to determine to be fit to local best building block size, and the size of void content; In China according to the region difference, the building block size leniently 150,180,240,300 arrives 360mm, length has 240mm, 300mm, 360mm according to the aggregate weight, but height must be 115mm, this is a clay building block standard of carrying out China, its purpose is to reduce construction cost, speeds up the work, and reduces labour intensity.
According to the weather conditions and the energy-saving heat preserving requirement of each region, determine the width and the partition grooves number of partition grooves, reaching the energy-saving heat preserving requirement, various places are energy-conservation to be required different and is reflected to the value difference of the complex heat transfer coefficient K of space enclosing structure, according to formula K=1/ (1/ α 1+ ξ (σ/λ)+AR 0+ 1/ α 2).
Wherein: α 1Heat emission factor w/m for inner wall surface 2K; α 2Heat emission factor w/m for exterior wall surface 2K; λ is the coefficient of thermal conductivity w/mK of building material; σ is the thickness m of building material; R 0Thermal resistance m for partition grooves 2K/w; A is the bar number of partition grooves.
The aggregate of each department is different, at first is ground into particle and is not more than 10mm, after the radioactivity of determining not have to be harmful to through the chemical analysis composition, requires to determine the aggregate prescription according to building structure, and determines the partition grooves number according to energy-conservation requirement.
Mould aggregate composition is assorted, and is pressed onto block forming through stirring extruding, and what economic strength was arranged advances the high pressure culture device, general is no less than 28 days to the open-air health in place duration of insurance, reaches requirement.
In order to accelerate the hardenability of building block, reduce the quantity of stripper plate, add 5% gypsum (CaSO in the composition of the present invention 3), sclerosis is fast, and approximately 30-50 minute is that available hand takes up.
