【摘要】：在我国,建筑耗能约占全社会耗能的1/3。墙体材料是我国建筑业的重要组成部分,大多砌块的生产过程都是高耗能、高排放、高污染的过程。国家提出墙体材料改革为新型混凝土砌块的应用提供了一个新的机遇。断桥混凝土复合保温砌块是一种新型墙体材料,它集保温、环保、节能、节土、围护等功能于一体新型墙体材料,多年来新型砌块难以普遍应用,归根结底是生产工艺不够成熟,设计和施工技术不够规范。本文通过试验,研究了复合混凝土砌块和砌体的基本力学性能和分析。1)砌块强度试验。根据试验得出每批砌块的强度试验值,看是否能够达到砌块的目标强度,为生产厂家提供数据依据。2)对断桥混凝土砌块砌体的基本力学性能进行试验。分别做砌体抗压强度试验、砌体沿墙面内和沿墙面外抗剪强度试验、砌体沿通缝抗弯试验和沿齿缝抗弯试验,对结果数据进行分析,提出对混凝土砌块生产的改进建议。根据试验结果和规范标准得出砌体的抗压、抗剪、抗弯等强度设计值。3)泊松比和弹性模量。在抗压强度试验的基础上,用位移计测试件的纵向变形和横向变形,荷载传感器测量荷载,计算得出砌体的泊松比和弹性模量。4)对砌体在实际工程中对应的力学问题进行分析计算。根据试验结果和计算得出的砌体的各强度设计值,对素填充墙的墙体进行抗风分析,素填充墙进行抗震分析,对填充墙体的构造进行设计和填充墙的连接件设计。通过以上的试验研究和分析为断桥混凝土复合保温砌块的推广及应用提供必要的基本力学性能指标和理论依据,亦为辽宁省地方标准的编制提供技术参数。
[Abstract]:In China, building energy consumption accounts for about a third of the total social energy consumption. The wall material is an important part of the construction industry in our country, and the production process of most masonry blocks is a process of high energy consumption, high emission and high pollution. The reform of wall material provides a new opportunity for the application of new concrete block. Broken bridge concrete composite insulation block is a new type of wall material, which integrates the functions of heat preservation, environmental protection, energy saving, soil saving and enclosure. In the final analysis, the production process is not mature enough, design and construction technology is not standard enough. In this paper, the basic mechanical properties and analysis of composite concrete block and masonry are studied by means of tests. According to the test results, the strength test value of each block is obtained to see whether the target strength of the block can be achieved or not. 2) the basic mechanical properties of concrete block masonry with broken bridges are tested. Tests on compressive strength of masonry, shear strength tests of masonry along and out of walls, bending tests of masonry along joints and flexural tests along tooth joints are made respectively. The result data are analyzed and suggestions for improvement of concrete block production are put forward. According to the test results and the criterion, the design values of compressive, shear and flexural strength of masonry are obtained. 3) Poisson's ratio and elastic modulus. On the basis of compressive strength test, load sensor is used to measure the load by measuring the longitudinal and transverse deformation of the parts with the displacement meter. The Poisson's ratio and elastic modulus of masonry are calculated. 4) the corresponding mechanical problems of masonry in practical engineering are analyzed and calculated. According to the test results and the calculated design values of masonry strength, the wind resistance analysis of the wall filled with primary wall, the seismic analysis of the wall filled with element, the design of the structure of filled wall and the design of connectors of filled wall are carried out. Through the above experimental research and analysis, this paper provides the necessary basic mechanical performance indexes and theoretical basis for the popularization and application of broken bridge concrete composite insulation block, and also provides technical parameters for the compilation of local standards in Liaoning Province.
