Abstract
Systems and methods for constructing staircases are described herein. The systems include a stringer hanger bracket for coupling a stair stringer of the staircase to an upper floor, two or more tread support structures and a jig. Each tread support structure is configured to couple a tread to the stair stringer. The jig is configured to determine a mounting position of each of the tread support structures on the stair stringer, determine a mounting position of each of the tread support structures on the stair stringer and/or determine a length of the stair stringer.
Claims19
A system for constructing a staircase having a plurality of treads, each tread having a predetermined run and a selected rise, the system comprising:
- a hanger bracket configured to couple a stair stringer of the staircase to an upper floor;
- a plurality of tread support structures, each tread support structure configured to couple a tread to the stair stringer;
- and
- a jig comprising:
- a first component;
- and
- a second component movably coupled to the first component, each of the first component and the second component having at least one scale thereon, each scale having a set of markings, each marking of each set of markings representing a different potential rise of each tread of the staircase, the jig having a first position where:
- an edge of one of the first component and the second component of the jig identifies a position of a cut line on the stair stringer of the staircase, the cut line identifying a bottom of the stringer that engages the ground, when:
- the jig is wresting on the stair stringer;
- the first component and the second component are coupled to each other;
- and
- one of the first component and the second component has an indicator pointing to a marking of a first scale of the other component, the marking indicating the selected rise of each tread of the stair stringer of the staircase.
A jig for constructing a staircase having a plurality of treads, each tread having a predetermined run and a selected rise, the jig comprising:
- a first component;
- and
- a second component movably coupled to the first component, each of the first component and the second component having at least one scale thereon, each scale having a set of markings, each marking of each set of markings representing a different potential rise of each tread of the staircase,
- the jig having a first position where:
- an edge of one of the first component and the second component of the jig identifies a position of a cut line on a stair stringer of the staircase, the cut line identifying a bottom of the stringer that engages the ground, when:
- the jig is at a first position resting on the stair stringer;
- the first component and the second component are coupled to each other;
- and
- one of the first component and the second component has an indicator pointing to a marking of a first scale of the other component, the marking indicating the selected rise of each tread of the stair stringer of the staircase.
