粉煤灰和煤矸石烧结多孔砖砌体性能研究
|
摘要
随着我国“禁实”系列法令的颁定及新型墙体材料研究工作的不断推进,粉煤灰和煤矸石烧结多孔砖在我省得到广泛应用,是具有广阔应用前景的新型墙体材料。按照我国建设循环经济和节约型社会的要求,为了保护环境,节约土地和资源,山西省建筑科学研究院与太原理工大学联合成立了“粉煤灰和煤矸石烧结多孔砖砌体性能研究”课题组,针对粉煤灰和煤矸石烧结多孔砖砌体的以下各方面性质进行了研究:
(1)对近年来生产的粉煤灰和煤矸石烧结多孔砖本身的性质进行了跟踪检测。对砌体结构进行基本力学性能试验。得到抗压强度、抗剪强度,与规范要求进行对比,并对破坏过程进行分析,对弹性模量、变形曲线、泊松比进行了分析计算。
(2)利用有限元分析软件ANSYS对粉煤灰和煤矸石烧结多孔砖砌体结构试验楼进行静力荷载下的受力与变形分析,在此基础上,对试验楼进行结构抗震动力分析。
(3)对烧结多孔砖砌体进行热工性能试验,对多孔砖砌体的保温性能进行测定。结合新型的保温材料——玻化微珠保温砂浆,推出了烧结多孔砖砌体内保温体系,并设计了对构造柱、圈梁、窗户等冷桥部位的构造措施,用ANSYS对其进行二维热工稳态传热模拟。
试验研究表明,粉煤灰、煤矸石烧结多孔砖本身性质很好地满足国家规范的要求;砌体的基本力学性能从变形到破坏与粘土砖的基本上一致,得到合理的弹性模量、波松比等;通过其静力模拟,可知粉煤灰、煤矸石烧结多孔砖砌体结构在对称荷载作用下,结构变形、应力呈正对称性,其变形及受力情况符合理论分析结果,墙体整体上处于受压状态,充分发挥了粉煤灰、煤矸石烧结多孔砖砌体优越的抗压性能;通过模态分析,得到自振周期、频率,在一般的砌体结构变化范围之内;通过谱分析得知结构剪力、变形都很小,结构的地震反应以低阶振型反应为主,结构的变形主要以剪切变形为主;通过热工试验得到多孔砖砌体合实际的传热系数及加保温层的传热系数;通过内保温热工模拟,证实了窗边保温的必要性,分析结果表明,本文建议的内保温体系可以显著的减轻冷桥效应,取得良好的保温。
通过本试验组的研究分析表明,粉煤灰、煤矸石烧结多孔砖砌体不仅有良好的承载力及抗震性能,且内保温体系保温效果良好,可以满足建筑节能标准要求。
本课题为省委示范项目,得到省内相关单位及粉煤灰、煤矸石生产产家的大力支持,为试验研究的顺利进行奠定了坚实的基础。粉煤灰、煤矸石烧结多孔砖砌体结构具有广阔的工程实用价值,市场前景良好,能在城镇及广大农村中广泛应用。
With the promulgation of the "forbiding reality" series laws and the new wall material research work's unceasing advancement,the fly ash and coal gangue burned porous brick is obtained the widespread application in our province,it is new wall material which has broad application prospect .In order to protect the environment、hooverize land and resource,a team of "study on the performance of fly ash and coal gangue burned porous brick masonry" is founded by Shanxi Construction Science Academe and Taiyuan University of Technology,below various aspects research is conducted:
(1).Carryed on the track examination to the nature of the fly ash and coal gangue porous brick. The basic mechanical behavior testing is done . Carryed on the contrast with the standard request,obtained its compressive strength, the shearing strength and carryed on the analysis contrast to its destruction process, its modulus of elasticity, the deformation curve, the Poisson's ratio .
(2).The finite element analysis software ANSYS is used to carry on the stress and the distortion analysis under the static load of the fly ash and coal gangue burned porous brick masonry structural testing building,and based on this, the structure earthquake resistance mechanical analysis on the experimental building is done .
(3).Heat engineering performance test is done to burned porous brick masonry,and carryed on determine to the heat preservation capability of it. Unifyed the new thermal insulation material—thermal insulation glazed hollow bead mortar,burned porous brick masonry inner heat preservation system is promoted, the hot bridge spot method to the ring bear,constructional column and window is proposed.It is done the two-dimensional hot working heat transfer in steady state simulation with ansys.
The analysis research indicated that, the fly ash and coal gangue burned porous brick itself nature is very good satisfied to country standard request; The basic mechanics performance from distortion to distort basically is consistent to the destruction with the loam brick, obtaining modulus of elasticity,the poisson' s ratio and so on; Through its static simulation, may know the fly ash and coal gangue burned porous brick masonry under the symmetrical load function, the structure distorts, the stress presents the symmetry, its distortion and the stress situation conform to the theoretical analysis result, in the wall whole is at the bearing condition, fully displayed the resistant to compression performance of the fly ash and coal gangue burned porous brick masonry; Through the modal analysis, obtains the reasonable natural vibration period, the frequency, in the body structural change scope; Through the spectrum analysis knew the structure shearing force, the distortion very is all small, the structure earthquake responds always by the low step inspiring response primarily, structure distortion mainly detrusion primarily; Through the heat engineering test ,obtaining the heat transfer coefficient of itselfe and adding heat insulating layer; Through heat engineering simulating, confirmed in the necessity of the window keeping warm, the inner heat preservation system which issuggested by this article can be possible remarkable to reduce the cold bridge effect, obtains good heat preservation.
Through this experimental group's research analysis indicated that: the fly ash and coal gangue burned porous brick masonry not only has the good supporting capacity and the earthquake resistance performance also the inner heat preservation system has good heat preservation effect, may satisfy the construction energy conservation standard request.
This topic is the provincial party committee demonstration project, obtains vigorously support by the coherent unit and the fly ash and coal gangue burned porous brick manufacturers in the province, laying the solid foundation to the experimental study.It has the broad project practical value, the market prospect is good,it can be widespread application in the cities and the general countrysides .
