哈尔滨银河大酒店增层改造设计

哈尔滨银河大酒店为22层高层建筑,裙房部分为6层,塔楼部分有3层地下室,裙房部分有1层地下室,裙房右侧为4层框架结构俱乐部。塔楼部分为钢筋混凝土框架-剪力墙结构,裙房部分为钢筋混凝土框架结构。为将原高层与俱乐部所夹裙房由6层增层至22层,依据原房屋柱下基础的不同形式,对原柱下桩基础进行叠合加固,对原柱下独立基础用新增桩基础替换,并对原框架柱加固。由于裙房柱网布置与其新增楼层的柱网布置不同,在7层顶设置梁式转换结构。对本工程增层改造设计的若干关键问题的解决方法做了介绍,可供同类工程增层改造设计时参考。

DESIGN FOR ADDING STOREYS AND STRUCTURE RECONSTRUCTION PROJECT OF HARBIN YINHE HOTEL

Harbin Yinhe Hotel is a 22-story high rise building,its annex is a 6-story structure with a 1-story basement,and its tower has a 3-story basement.On the right of the annex is a club of 4-story frame structure.The tower is a RC frame-shear wall structure,and the annex is a RC frame structure.In order to make the 6-story annex surrounded by the high rise building and the club becoming a 22-story structure,the original pile foundation under the column is reinforced by casting new concrete and placing reinforcements around the column to forming a big pile.The original independent foundation under the column is replaced by the new pile foundation,and the original frame columns are strengthened.For the column grids of annex and new structure are different,the transfer beam structure is set up on the top of 7th floor.The solution for some key problems in design of the reconstruction project is introduced,which can be served as reference for similar projects.
