Title:
LOAD TRANSFER PLATE FOR IN SITU CONCRETE SLABS
Document Type and Number:
WIPO Patent Application WO2003023146
Kind Code:
A9
Abstract:
A tapered load plate transfers loads across a joint between adjacent concrete floor slabs. The top and bottom surfaces may taper from approximately 4 inches wide to a narrow substantially pointed end over a length of approximately 12 inches. The tapered load plate accommodates differential shrinkage of cast-in-place concrete slabs. When adjacent slabs move away from each other, the narrow end of the tapered load plate moves out of the void that it created in the slab thus allowing the slabs to move relative to one another in a direction parallel to the joint. Tapered load plates may be assembled into a load-plate basket with the direction of the taper alternating from one tapered load plate to the next to account for off-center saw cuts. A tapered load plate and an end cap may be used to provide load transfer across an expansion joint.
