摘要
某5层砖混结构会所需拆除3、4层部分承重墙,改造成大空间的房间。由于承重墙拆除后,圈梁不足以承担楼面荷载,采用了钢柱、钢梁托换3、4层墙体,托换后圈梁通过钢板垫块与托换钢梁有效连接的方案。
In a five-story chamber,the brick walls on the third and fourth floors will be removed to get a bigger room.Then the bond beams can＇t support the floor loads.To reinforce the bond beam,an effective scheme consisting of steel columns,steel beams and steel pads between steel-beam and bond beam is designed.
