【摘要】 目前,发展低碳型节能建筑的关键是节能减排、降低建筑能源消耗。而墙体革新是实现建筑节能的基础。为此我国加快了墙体改革的步伐,加大了对新型墙体材料的推广力度,加强了对有碍于建筑节能行为的执法力度。建筑节能标准也逐渐由原来的30%到50%再到如今的65%。本文所提出的新型墙体材料—复合保温空心砌块,不仅满足了当前建筑节能标准的要求,减少了建筑能源消耗,而且为低碳节能建筑材料的发展提供了相应的试验与理论依据。(1)本文从复合保温混凝土空心砌块的材料选择、块型设计、生产设备以及生产工艺等方面做了相关的研究与讨论,并介绍了新型复合保温空心砌块的生产线—FZBW6—30型保温砌块成型设备生产线。(2)力学性能：试验设计时力学试验主要参考了砌体的基本力学性能以及实际运用过程中所应掌握的各项性能指标,新型复合保温砌块砌体的抗压、抗剪强度的试验值与规范值基本吻合,只是抗剪强度略显偏低；而承载力计算时,计算截面面积应选取承重块的截面面积进行计算,因保温层与外装饰结构对承载力的影响较小,可忽略。(3)热工性能：复合混凝土空心砌块砌体结构的保温隔热性能是建筑节能工程设计中的重要指标,主要是通过热阻和传热系数表现出来。复合保温空心砌块砌体结构的传热值满足建筑节能标准65%的要求。热工性能的检测方法主要有两种：试验检测法和间接理论计算法。对比两种方法可知,间接法在开发新产品或设计新的建筑结构形式时,更具有其显著的优点。(4)通过对复合保温空心砌块的热工试验及物理性能进行研究与分析,初步验证了填加保温材料的砌块其保温隔热性能明显高于普通混凝土空心砌块,用于维护结构中可显著较少夏季空调及冬季供暖系统的使用费用,从而达到节能减排的要求,而且复合保温空心砌块的混凝土用量是普通混凝土砌块的88%。假设单位体积内混凝土的碳排放量相同,则降低碳排放量12%。本文中通过对复合保温砌块的力学与热工性能做了基本的试验研究,并对砌块的碳排放量进行了分析,可知复合保温空心砌块对于节约能源,保护环境,实现良好的低碳生活具有深远的研究意义。更多还原

【Abstract】 In nowadays,The key measures for energy-saving and reducing consumption of building energy is to develop low carbon and energy-saving building.Wall innovation is the foundation for energy saving building.Due to this,our country has quickened the pace of walling reform,spare no effort to promote the new wall materials.Strengthen the enforcement of law to encourage the behaviors for energy-saving building have gradually from 30% to 50% then to 65% today.This paper puts forward a kind of new wall materials—composite insulation hollow blocks,not only satisfy the current energy-saving standard requirements,reduce the building energy consumption,but provides for low carbon energy-saving building development corresponding experiment and theoretical basis.(1)Through research on the composite insulation materials selection,block type design, production equipment and production technology of the concrete hollow blocks,then introduces a new composite thermal-insulating blocks and its use of the FZBW6-30 type thermal-insulating blocks molding equipment production line.(2)Mechanical properties:Design Mechanical test is mainly relating to the basic mechanical properties of masonry and its practical application in the course of the performance indicators to be grasped.the compressive strength of the new composite insulation masonry and test values of shear strength are consistent with the code,only slightly lower shear strength.However,when calculating the ultimate bearing capacity,calculation section area is should adopt the bearing block section area is calculated with the external decoration, because the thermal insulation layer of the bearing capacity of less influence structure, can be omitted.(3)Thermal performance:Composite concrete hollow block’s energy-saving thermal performance is an important indicator in the designing of energy-saving building and it’s mainly represented by the thermal resistance and heat transfer coefficient shown.Composite insulation hollow heat transfer value satisfy building energy-saving criteria 65% of requirements.The thermal performance testing method to basically have two kinds:direct and indirect test detection theoretical calculation method. Contrast,when adopting standard calculating methods on developing new products or design new building structures and it has significant advantages.(4)Through experiment and theoretical calculation primarily validated the reclamation and heat preservation material blocks its insulation effect significantly higher than normal concrete hollow blocks,used for maintenance structure can significantly less air-conditioning in summer and winter heating system,so as to achieve the utilization of energy saving and emission reduction requirement,and composite insulation hollow blocks of concrete consumption is ordinary concrete block of 88%. So as to reduce carbon emissions by 11%.In the paper,for composite thermal-insulating blocks of mechanical and thermal performance made basic experimental research,and to block of carbon emissions are analyzed, knowable composite insulation hollow blocks for energy saving and environment protecting, achieve good low carbon life is of far-reaching significance.更多还原
