摘要:
A precast concrete slab for forming a deck in a bridge superstructure has a chamfer on forward and trailing edges so that adjacent slabs can mate. The slab is reinforced with bars which protrude laterally from the slab on opposite sides and which, in use, extend over support beams. Selected bars are formed in a castellated shape of which inverted U-shaped portions extend above the surface of the precast concrete slab. Conveniently, the U-shaped portions anchor a concrete topping which is poured over the slabs at a bridge site and also provide locations for hooking a crane used to transport the slab at a site.
摘要(中):
用于在桥梁上部结构中形成甲板的预制混凝土板在前缘和后缘具有倒角,使得相邻的板可以配合。 板坯由在相对侧面上从板坯横向突出的棒材加强,并且在使用中,在支撑梁上延伸。 所选择的棒形成为其倒置的U形部分在预制混凝土板的表面上方延伸的雉形形状。 方便地,U形部分将混凝土顶部固定在浇筑在桥梁位置的板上,并且还提供用于钩住用于在现场运输板坯的起重机的位置。
