某商场楼梯改造为扶梯的工程设计

A DESIGN OF RECONSTRUCTING STAIR INTO ESCALATOR FOR A MARKET

在对某楼梯改造为自动扶梯的工程设计中 ,在考虑选用交叉布置还是平行布置时 ,应满足扶梯净空等使用要求。为支撑扶梯 ,在框架梁上端需植筋用作牛腿 ,下端需新加梯梁。为锚固新加梯梁的底部受力筋 ,将支承梯梁的框架梁梁底加大截面。在主梁与新加次梁连接处 。

In a design of reconstructing a stair into an escalator,the headroom of the escalator should be thought over when the escalator is decided to be disposed in cross or parallel.In order to support the escalator,rebar-implanting should be done at the upper end of the frame girder,which is used as a bracket;a new beam should also be added to the lower end of it.In order to anchor steel bar of the new beam,section area of the frame girder bottom should be enlarged.On the join of the girder and the beam,a hoop should be added.
