A construction method for a spar platform cylindrical deck and upper facilities, and a spar platform. The construction method is as follows: prefabricating upper facilities (2) in modules one by one,after prefabrication of the modules is completed, lifting the modules to a predetermined position of the uppermost deck the a cylindrical body (1), and then connecting the modules to each other and forming a module combination bottom deck at the bottom. Modules in the module combination are modules which have complete structures and can independently be lifted, or are multiple segmented modules formed by segmenting the module combination; during construction of the cylindrical body (1), a skylight opening is reserved on the uppermost deck of the cylindrical body (1) where the upper facilities(2) are mounted, and the module combination bottom deck is able to be placed in the skylight opening; a field closure gap is formed between the skylight opening and the module combination bottom deck;and the field closure gap is filled by means of a field closure connecting structure, so that the module combination bottom deck and the uppermost deck of the cylindrical body (1) together form an integral platform combination deck. The structural design and the construction method of the entire platform are optimized, steel materials are saved, platform construction costs are reduced, construction is facilitated, and the production operations are safe.
一种直筒式平台筒体甲板与上部设施(2)的建造方法及直筒式平台,所述建造方法如下:上部设施(2)先按模块一一预制,模块预制完成并一一吊装至筒体(1)的最上层甲板所在的预定位置后,再将模块彼此连接,其底部形成一个模块组合底甲板;所述模块组合内的所述模块为可以独立吊装的完整结构模块,或者为由所述模块组合分割而形成的多个分割模块;筒体(1)建造时,在用于安装上部设施(2)的筒体(1)的最上层甲板上预留一个天窗开口,天窗开口允许模块组合底甲板放置其内;天窗开口与模块组合底甲板之间形成现场合拢间隙;通过现场合拢连接结构(3),填补现场合拢间隙,使模块组合底甲板与筒体(1)的最上层甲板共同形成一体化的平台组合甲板。其实现整个平台的结构设计和建造方法优化,节约钢材、降低平台造价,方便建造、有利于生产操作的安全。
