大型塔器厂内分段制造的质量控制要点

Key Points for Quality Control of Large Block Manufactured Towers in the Plant

一部分大型塔器由于受到一些条件的限制,需要将塔分成几段在厂内制造。而这种分段制造的塔器如果厂内制造时质量控制不严格,极易在现场最终组对时出现部分尺寸超标。本文根据以往施工经验,探讨了塔器在厂内分段制造时,塔的总长度、塔器椭圆度和直线度以及塔盘支持圈水平度等方面质量控制要点,从而保证整台塔器的制造质量。

Some large towers need to be block manufactured in plant due to the limited condition. If the quality of this block manufactured towers is out of controlled, it’ll prone to mismatched when finally field fitting. According to previous construction experience, this paper discussed the key points of quality control concerning length, ovality and straightness of a tower as well as levelness of tray support circle, therefore the quality of the total tower is guaranteed.
