【摘要】：“十二五”国家科技支撑计划社会发展科技领域项目《保障性住房工业化设计建造关键技术研究与示范研究》,结合保障性住房工业化建筑体系的建筑设计、建筑施工、建筑材料等开展了关键部品产业化技术的研究。其核心是将房屋工程建设由传统“现场建造”变为“工厂制造、现场安装”。可以彻底解决传统建设模式带来的建筑耗能大,建造效率低下,建筑品质严重参差不齐等问题,符合国家战略发展的需求。本文主要对工业化生产的复合墙板,在工厂生产过程中脱模起吊以及施工现场安装工况下,研究复合墙板的脱模吊装方案、受力性能及起吊设计,确保吊装过程复合墙板完好。研究采用调研、理论分析和有限元模拟的方法,主要得到了以下结论：(1)研究了影响复合墙板脱模起吊的因素和国内外规范给出的脱模吸附系数,提出本文脱模起吊计算时复合墙板的脱模吸附系数。(2)分析了复合墙板在起吊时绳索的受力,并通过计算得出了复合墙板起吊角度的最佳取值范围；对普通的梁板在起时的吊点位置进行了设计,并将这个设计方法推广到复合墙板,通过计算与推导得出复合墙板吊点的设计公式,利用此公式可以求出不同尺寸复合墙板的最佳吊点；验算了复合墙板在起吊过程中螺栓、吊环的受力性能、吊梁的刚度及稳定性。(3)利用sap2000对复合墙板在脱模起吊及现场安装这两种不同的受力形式进行了模拟计算,并根据计算结果分析吊点设计公式的合理性；模拟计算了复合墙板在起吊过程中可能出现的三点受力的特殊情况；模拟计算了复合墙板在脱模起吊过程中底模的受力情况,并对底模进行变形分析。
[Abstract]:"the 12th Five-Year Plan" National Science and Technology support Plan Social Development Science and Technology Project "Research and demonstration study on the key Technologies of the industrialized Design and Construction of affordable Housing", combined with the architectural design of the industrialized building system of the supportable housing. Construction, construction materials and so on have carried out the research on the industrialization technology of key parts. The core of which is to change the building construction from the traditional "on-site construction" to "factory manufacturing". Site installation ". Can completely solve the traditional construction mode of building energy consumption, low construction efficiency, building quality seriously uneven and other problems. In line with the needs of the national strategic development. This paper mainly on the industrial production of composite wall panels, in the factory production process of demoulding lifting and construction site installation conditions, the study of composite wall panel demoulding lifting scheme. Mechanical performance and lifting design to ensure that the lifting process of composite wallboard intact. Research, theoretical analysis and finite element simulation method. The main conclusions are as follows: 1) the factors that affect the demoulding and lifting of the composite wall panel and the desorption coefficient given by the domestic and foreign norms are studied. In this paper, the removal adsorption coefficient of composite wall board is put forward in the calculation of demoulding lifting. The force of rope on composite wall board is analyzed, and the optimum value range of lifting angle of composite wall board is obtained by calculation. In this paper, the lifting point position of the common beam and slab is designed, and the design method is extended to the composite wall board, and the design formula of the hanging point of the composite wall panel is obtained by calculation and derivation. By using this formula, the optimal lifting point of composite wall panels with different sizes can be obtained. The mechanical properties of bolts and rings in the lifting process of composite wallboard are checked and calculated. The stiffness and stability of the beam are simulated and calculated by sap2000. According to the calculation results, the rationality of the design formula of the lifting point is analyzed. The special situation of three-point force which may appear in the lifting process of composite wall board is simulated and calculated. In this paper, the stress of the bottom die during the demoulding and lifting process of the composite wall board is simulated, and the deformation analysis of the bottom die is carried out.
