1 工程概况 染化六厂搬迁工程红、黄车间是在原染化八厂老厂房—还原棕车间不改变原结构的基础上通过加固改造后而建成的。此车间是四层混凝土框架结构,层高5 m,建筑面积5570m~2。 2 主框架结构加固设计与施工工艺选择原结构主框架中的51根梁和85个柱头需要加固。 2.1 梁的加固设计 将原梁底面的混凝土保护层剔去露出主筋,然后用φ25L=100 mm的连接短筋,将新增加的三根
1 Project Overview The red and yellow workshops of the relocation project of the No. 6 Chemical Plant were built after the reinforcement and reconstruction of the original plant of the original No. 8 factory, the reductive brown workshop, without changing the original structure. This workshop is a four-story concrete frame structure with a height of 5 m and a building area of 5570 m2. 2 Reinforcement design and construction process of the main frame structure The 51 beams and 85 column heads in the main frame of the original structure need to be reinforced. 2.1 Reinforcement Design of Beams Remove the concrete protection layer on the underside of the original beam to expose the main reinforcement, then use φ25L=100 mm to connect the short reinforcement, and add three new ones.
