近几年来,随着社会主义建设事业的发展,高层建筑不断增加,其中很多建筑采用框架结构。现就我们这几年来的施工实践,对高层框架结构施工工艺和保证质量问题,谈谈我们的粗浅体会。一、准备工作1.构件检查根据构件制作允许偏差,检查或抽查构件几何尺寸是否超出允许偏差范围,同时检查构件型号、预埋件位置等。2.放线工作(1)控制轴线,根据建筑物的造型,在纵横轴线上设置控制桩,其位置要便于保护,便于测设(在市内施工,现场周围建筑物较多,也可放在建筑物上)。(2)每层放线,以控制轴线引出全部
In recent years, with the development of socialist construction, high-rise buildings have been increasing, many of which use frame structures. Now let’s talk about our superficial experience on the construction practices of our past few years, on the construction process and quality assurance of high-level frame structures. First, the preparation 1. Component inspection According to the component manufacturing tolerances, check or check the component geometry is beyond the allowable deviation range, at the same time check the component model, embedded parts and so on. 2. Take off the line work (1) Control the axis, according to the shape of the building, set the control pile on the vertical and horizontal axis, the position should be easy to protect, easy to measure and set up (in the city construction, more buildings around the site, can also put On the building). (2) Payouts on each floor, leading to the control axis
