Adjustable dap assembly
View Patent ↗A vertically adjustable steel reinforcing assembly, especially adapted for effective use with dapped beam ends. The reinforcing assembly includes an upper assembly and a lower assembly. Running vertically through the center of each of the assemblies are aligning pin holes. Assembly is configured at the time of casting to accommodate most recent dap design.
1. A two piece adjustable support structure for casting into a concrete beam dap comprising:
an upper member comprising a vertical section and a lateral section and a lower member;
said upper member vertical section comprising a width, a material thickness, a top edge, a bottom edge, two sides, and a height which exceeds a vertical depth of the dap which the adjustable support structure will be cast into;
said upper member lateral section comprising a material thickness, which protrudes from the vertical section between the vertical section top edge and vertical section bottom edge where the lateral section has a top edge that extends from the vertical section at a downward angle to an end point, a bottom edge that extends perpendicularly from the vertical section to an end point, and a vertical edge which is parallel to the upper member vertical section and connecting end points of the vertical section top edge and bottom edge;
a downward facing ell shaped lateral bearing plate with a bearing plate lateral section, a bearing place vertical section, and a bearing plate width, aligned to the bottom edge of the upper member lateral section, oriented perpendicularly with the upper member lateral section, wherein the width of the bearing plate exceeds the material thickness of the upper member lateral section and the bearing plate is affixed to the upper member lateral section where the lateral section of the lateral bearing plate is affixed to said upper member lateral section and the vertical section of the horizontal bearing plate is affixed to the upper member vertical section;
wherein said vertical section of said upper member has an upper section which extends above said upper member lateral section of the horizontal support member and a lower section which extends below said upper member lateral section;
said lower member comprising a vertical section comprising a width, a material thickness, a top edge, a bottom edge, two sides, a height, and an upward facing ell shaped vertical bearing plate with a bearing plate horizontal section, a bearing plate vertical section, a bearing plate depth and a bearing plate material thickness, aligned to the bottom edge of the lower member, oriented perpendicularly with the lower member, wherein the width of the vertical bearing plate exceeds the material thickness of the lower member and vertical bearing plate horizontal section is affixed to the lower member at both the bottom edge and at least one side;
a means for allowing the upper member to be securably connected to the lower member at multiple vertical locations along the vertical support member;
wherein said upper member and said lower member can be aligned and securable affixed to each other at a proper vertical height to match the dimensions of a-dapped end at the time of casting the concrete beam dap.
2. The adjustable support structure for casting into a beam dap of claim 1 , wherein said means for allowing the horizontal support member connection flange to be securably connected to the vertical support member at multiple vertical locations along the vertical member is comprised of a plurality of aligning pin holes running vertically through both the horizontal support member connection flange and the vertical support member and a plurality of press fit pins.
