Abstract
A system and method for forming changes in elevation in a concrete slab includes one or more channels having substantially parallel bottom and top edges. The bottom and top edges include bent ends and a number of spaced apertures are formed in the bottom and top edges and the bent ends. Braces are inserted into the apertures to support the channel or channels in a vertical position. On or more different type bolt holders are selectively insertable into the channels for holding “J” bolts in a vertical position, parallel to the channels. Connecting elements are included for holding adjacent ends of separate channels together.
Claims17
A permanent, in-place system for forming changes in elevations in a poured concrete surface, comprising:
- at least one channel-shaped body having a first elongated surface with bottom and top edges secured thereto at approximately 90°;
- a plurality of spaced brace-holding means formed in the bottom and top edges;
- at least one substantially U-shaped bolt-holding bracket, inserted and held in the at least one channel-shaped body between facing surfaces of the bottom and top edges;
- and
- a plurality of bracing elements for insertion into selected ones of the plurality of brace holding means for supporting the at least one channel-shaped body in a vertical position, with the bottom and top edges substantially parallel to a surface to be covered by concrete.
A permanent, in-place system for forming changes in elevations in a poured concrete surface, comprising:
- at least one channel-shaped body having a first elongated flat surface with bottom and top edges extending therefrom at approximately 90°;
- a plurality of spaced openings formed in the bottom and top edges;
- a plurality of spaced apertures formed on outer ends of the bottom and top edges;
- and
- a plurality of bracing elements having shaped ends for insertion into selected ones of the plurality of spaced apertures for supporting the at least one channel-shaped body in a vertical position, with the bottom and top edges substantially parallel to a surface to be covered by poured concrete.
A permanent, in-place system for forming changes in elevations in a poured concrete surface, comprising:
- a plurality of channel-shaped bodies having elongated surfaces with substantially perpendicular bottom and top edges;
- the substantially perpendicular bottom and top edges having bent ends formed thereon;
- a plurality of spaced apertures formed in the substantially perpendicular bottom and top edges and extending into the bent ends;
- means for holding the plurality of channel-shaped bodies together;
- a plurality of bracing elements having shaped ends for insertion into selected ones of the plurality of spaced apertures for maintaining the plurality of channel-shaped bodies in a vertical position with the bottom and top edges substantially parallel to a surface to be covered by concrete;
- a plurality of bolt holders having aligned openings therein inserted and held in the plurality of channel-shaped bodies between the substantially perpendicular bottom and top edges;
- and
- a plurality of “J” bolts held in the aligned openings in the bolt holders and extending substantially parallel to the vertical channel-shaped bodies.
