【摘要】：从二十世纪初一直到今天,我国城市建筑在短短的几十年时间里经历了翻天覆地的变化。从原始的“秦砖汉瓦”到现代的钢筋混凝土再到装配式建筑,我国建筑业的工业化和现代化水平逐渐提高。由于装配式建筑的装配件能够在工厂里生产,而且现场可以装配式施工,实现了真正意义上的工业化和现代化生产,同时由于环境污染严重及能源消耗过快严重制约了社会的发展,所以国家提出要大力发展绿色节能型的装配式建筑。首先为了响应国家的绿色节能的号召,本文通过合理的配合比设计和试验,研究发明了一种新型混凝土-小麦秸秆混凝土。作为农业大国小麦秸秆可谓是资源丰富,但是每年产出的小麦秸秆却没有得到合理的利用。本文对小麦秸秆混凝土进行了系统的研究,通过合理的配合比设计研制出了一套特有的配制方法,结合试验对小麦秸秆混凝土的立方体抗压强度、轴心抗压强度、弹性模量等力学性能进行了一定深度的分析,并且对影响混凝土力学性能的各方面因素进行了对比分析。其次为了响应国家发展装配式建筑的号召,本文将小麦秸秆混凝土和钢筋桁架-楼承板相结合,研制出能够适用于装配式建筑的钢筋桁架-小麦秸秆混凝土组合楼板。钢筋桁架-楼承板可以在工厂里进行加工完成,满足了“工厂化生产、装配化施工”的工业化、现代化发展要求。本文通过试验和有限元分析,进一步研究了钢筋桁架-小麦秸秆混凝土组合楼板的受力性能和破坏形态,对影响其承载力的各因素进行逐一分析,并提出具有参考价值的理论计算公式。
[Abstract]:From the beginning of the twentieth century to today, urban architecture in China has undergone earth-shaking changes in a short period of several decades. From the primitive "Qin brick and Han tile" to the modern reinforced concrete and assembly building, the industrialization and modernization level of Chinese construction industry has been gradually improved. Because assembly parts of prefabricated buildings can be produced in factories, and assembly construction can be carried out on the spot, real industrialization and modern production have been achieved. At the same time, because the environment pollution is serious and the energy consumption is too fast, the development of the society is restricted seriously, so the country proposes to develop the green and energy saving prefabricated building energetically. In order to respond to the call of green energy saving in our country, a new type of concrete, wheat straw concrete, was developed through reasonable mix ratio design and experiment. As a big agricultural country, wheat straw is rich in resources, but the wheat straw produced every year has not been used reasonably. In this paper, the wheat straw concrete has been studied systematically, and a set of special compounding method has been developed through reasonable mix ratio design. The cube compressive strength and axial compressive strength of wheat straw concrete have been tested. The mechanical properties such as modulus of elasticity are analyzed in depth, and the factors affecting the mechanical properties of concrete are compared and analyzed. Secondly in order to respond to the call of the national development of prefabricated building this paper combines wheat straw concrete and steel truss-floor slab to develop the composite floor slab of reinforced truss-wheat straw concrete which can be used in the prefabricated building. The steel truss-floor slab can be processed in the factory, which meets the requirements of industrialization and modernization of "factory production and assembly construction". By means of test and finite element analysis, the mechanical behavior and failure pattern of reinforced truss-wheat straw concrete composite slabs are further studied, and the factors affecting their bearing capacity are analyzed one by one. A theoretical calculation formula with reference value is put forward.
