发明名称 System and Method for Concrete Slab Connection
摘要 Systems and methods of transferring loads between adjacent cast-in-place slabs, such as concrete slabs, and for accurately positioning dowels between adjacent sections of slabs are provided. A generally planar plate-type dowel is used which may be positioned within a cutaway in a preexisting slab of concrete. The dowel is shaped to generally conform to the shape of the cutaway, which is made by a saw blade. Once the dowel is positioned within the preexisting slab, a new slab is poured adjacent the preexisting slab. Rubber seals are included on the edges of the dowels to provide spacing or a gap between the dowel and the preexisting slab to allow for lateral independent movement of the adjacent slabs, and to prevent concrete from the newly poured second slab from entering into the gap. A saw unit for making a generally planar cut horizontally into an edge of a hardened concrete slab is also provided.
