    • PROBLEM TO BE SOLVED: To downsize a member for loading an apparatus for home fence and reduce the construction period.SOLUTION: The structure of a precast concrete slab for home fence has two regions at different heights in a width direction of railroad rails. Among the two regions, the region close to the home rather than the railroad rail is lower. A control apparatus for home fence is arranged on the region at railroad rail side. On a height gap part between the region at the railroad rail side and the region at the home side, a cable trough for storing an electric power line and a signal line connected to the control apparatus for home fence is arranged. At a position where the control apparatus for home fence is arranged in the region at the railroad rail side, a female screw to which a base plate of the control apparatus for home fence is screwed is arranged, and a plurality of reinforcing bars extending in the width direction are arranged in parallel in longitudinal direction along with the railroad rail. A plurality of reinforcing bars extending in the longitudinal direction are crosslinked to a plurality of reinforcing bars extending in the width direction and being arranged in parallel in the longitudinal direction so as to maintain the intervals in parallel.
    • 要解决的问题:减小装载家庭围栏设备的成员,缩短施工期。解决方案:家庭围栏预制混凝土板的结构在铁路宽度方向上有两个不同高度的区域。 在这两个地区中,靠近家庭而不是铁路的地区较低。 在铁路一侧的区域设置有家庭围栏的控制装置。 在铁路轨道侧的区域和家庭侧的区域之间的高度间隙部分设置有用于存储电力线的电缆槽和连接到家庭围栏的控制装置的信号线。 在家用围栏的控制装置配置在铁路轨道侧的区域的位置,配置有用于家庭围栏的控制装置的底板被螺纹连接的阴螺纹,并且在该螺钉中延伸的多个钢筋 宽度方向与铁路轨道一起在纵向方向上平行布置。 沿长度方向延伸的多个钢筋与多个在宽度方向上延伸的钢筋交联,并沿长度方向平行配置,以使间隔保持平行。
