为了满足楼梯平台梁一下净空的尺寸,将平台梁内移一段,或当荷载不大,进深较短时,可做成折线形楼梯,见图1折线形楼梯通常按近似法计算,以梁或墙做为支点,求其弯矩,进行配筋,在配筋时,要特别注意折点处钢筋的放置方法:凸折角处楼梯板的底部钢筋a在折点处应伸至平台板顶后弯折,并延伸过去,再在平台板下部附加相同截面钢筋b,
In order to meet the clearance dimensions of the stair platform beam, the platform beam is moved within a section, or when the load is not large and the depth is short, it can be made into a zig-zag-shaped staircase. Figure 1 The zigzag staircase is usually calculated according to an approximate method. The wall serves as the fulcrum for its bending moments and reinforcement. When reinforcing steel, special attention should be paid to the placement of reinforcing bars at the folding point: at the corners of the ridges, the bottom of the step bars should be extended to the top of the platform plate at the break point. Bending, and extending in the past, and then attach the same section reinforced bar b to the lower part of the platform plate.
