发明名称 Method and apparatus for assembly of stair forms
摘要 Construction forms for making concrete forms for making stairs have a bracket with a stringer mount face and a riser mount face. Each mount face has mounting structure located thereon. A longitudinally extending stringer stop extends away from and perpendicular to a stringer mount plane in a first direction, the stringer stop having a surface adapted to abut a bottom of a stringer. A laterally extending first riser stop has a first riser abutting surface. The first riser stop extends laterally away from the riser mount face in a second direction and is longitudinally spaced a first distance from the stringier stop. The second direction is perpendicular to the first direction. The first riser abutting surface is adapted to abut a top of a riser. Use of the bracket in an assembly with a stringer and a riser are also disclosed.
