【摘要】：装配式混凝土结构是指以预制混凝土构件为主要受力构件,经装配连接而成的混凝土结构,是建筑产业化的一种新型结构形式。预制装配式建筑符合我国"十三五"规划以及党的十八大提出的建设节约型、友好型社会的要求,是近年来建筑工业化,住宅产业化的行业热点。预制装配式混凝土结构的施工主要包括预制构件制作、预制构件运输与堆放、预制构件安装与连接三个施工阶段。预制构件的吊装贯穿了装配式结构三个阶段的整个施工过程,是施工过程的中心环节。预制构件的吊装包括构件的脱模起吊、翻转、运输起吊及现场起吊等。起吊是否成功,预制件产品能否精确就位并使用直接关系到整个预制建筑能否顺利施工。因此,预制构件的安全吊装在整个装配式建筑的施工中起着举足轻重的作用。本文详细介绍了预制剪力墙板的吊装工序,吊装工艺,吊点的选择以及吊装设备的应用。以安徽宝业建工集团滨湖润园住宅产业化工程二标段项目为工程背景,本文采用理论计算与数值模拟相结合的方法对最具代表性墙板两点吊和三点吊进行抗拉、抗弯、抗裂强度验算。通过三点吊、两点吊的对比分析,得到采用两点吊与三点吊都能满足抗弯、抗拉及抗裂性能要求。但两点吊节省了吊钉,更具有经济优势。两点吊的吊装方案更合理,为进一步解决工程实践问题提供了借鉴。
[Abstract]:Prefabricated concrete structure is a new type of structure which is composed of precast concrete members and connected by assembly. Prefabricated buildings accord with the requirements of the Thirteenth Five-Year Plan of our country and the construction of energy-saving and friendly society put forward by the 18th National Congress of the Communist Party of China. It is a hot spot in the industry of building industrialization and housing industrialization in recent years. The construction of prefabricated concrete structure mainly includes three construction stages: prefabricated component manufacture, prefabricated component transportation and stacking, prefabricated component installation and connection. The hoisting of prefabricated components runs through the whole construction process of the three stages of prefabricated structure and is the central link of the construction process. The hoisting of prefabricated components includes demoulding lifting, overturning, transportation hoisting and site hoisting. Whether the hoisting is successful or not, whether the prefabricated products can be precisely positioned and used is directly related to the smooth construction of the whole prefabricated building. Therefore, the safety hoisting of prefabricated components plays an important role in the construction of assembly buildings. In this paper, the hoisting procedure, hoisting process, hoisting point selection and the application of hoisting equipment of prefabricated shear wall board are introduced in detail. Based on the second section project of Binhu Runyuan Residential industrialization Project of Anhui Baoye Construction Engineering Group, this paper adopts the method of combining theoretical calculation and numerical simulation to carry on the tensile and bending resistance to the most representative wall panel two-point hoisting and three-point hoisting. Crack strength check calculation. Through the comparison and analysis of three-point crane and two-point crane, it is concluded that both two-point crane and three-point crane can meet the requirements of bending, tensile and crack resistance. But two-point hoisting saves the hoisting nail, has the economical superiority. The lifting scheme of two-point crane is more reasonable, which provides a reference for further solving engineering practice problems.
