9 系列模数有孔砖宏观效益分析采用系列数多孔砖砌筑建筑物墙体,与普通砖相比,仅就砖的节约而言,其效益来自两个方面:模数化带来的节约和砖的孔洞节约.模数化带来的节约有:墙厚变化级差为半模,设计选用墙厚合理(它比普通砖墙厚度级差小 60%),节砖14%;砌墙不砍砖(普通砖砌墙砍砖至少要占 8%)节砖 1.9%;采用190mm厚墙体作承重墙(用普通砖时为 240mm厚墙)节砖 4.9%;由模数多孔砖墙热工效率提高(提高30%)而节砖11.2%,共计 32%.砖的孔洞节约:当孔洞率为30%时,孔洞体积的节约相当于节砖 20.4%.其节砖率的总和为 52.4%,以DM模数多孔砖和 KP_1多孔砖两者同普通砖相比的节约数列于表I0.
The macro benefit analysis of the 9 series modular perforated brick adopts a series of perforated brick masonry building walls. Compared with ordinary bricks, the benefit of bricks only comes from two aspects: the savings brought by modularization Hole saving in bricks and bricks. Savings due to modularity include: wall thickness variation is a half-module, wall thickness is reasonable (it is 60% smaller than normal brick wall thickness), brickwork is 14%, and wall is not cut. Bricks (ordinary brick wall chopped bricks account for at least 8%) of bricks 1.9%; 190mm thick walls for load-bearing walls (240mm thick walls for ordinary bricks), brickwork 4.9%; porous brick wall thermals by modulus Increased efficiency (by 30%) and saved 11.2% of bricks, totaling 32%. Hole savings in bricks: When the hole rate is 30%, the hole volume savings are equivalent to 20.4% bricks. The sum of the brick-making rate is 52.4%. The savings of DM modulus perforated bricks and KP_1 perforated bricks compared with ordinary bricks are listed in Table I0.
