Abstract
A bracket for use in manufacturing a step supported by a stringer. The bracket includes an anchor block to which a tread for a step may be attached, a pair of frames flanking the anchor block and fixed thereto, and markings formed on at least one of the frames. The markings indicate a rise and a run for the step. The bracket may be used in a method for building a stairs. The method includes the steps of selecting a desired tread distance and rise distance for the stairs to be built, fastening tread receiving portions and riser-receiving portions of a bracket to a first elongate stringer to define the desired tread and riser distances, repeating the above steps with respect to a second stringer, mounting a tread to the tread-receiving portions, and mounting a riser to the riser-receiving portions.
Claims16
A bracket for use in manufacturing a step supported by a stringer, the bracket comprising:
- an anchor block to which a tread for a step may be attached;
- a pair of L-shaped frames flanking the anchor block and fixed thereto;
- pre-formed markings formed on at least one of the frames, the markings indicating a rise and a run for the step.
A stair support system, comprising:
- plural L-shaped structural frames, each having an inner face, an outer face, and first and second legs disposed at approximately right angles to each other so that each leg may be cut or bent independent of the other leg, as needed;
- and
- an anchor block coupled between the inner faces of the structural frames to retain the frames in a corresponding, yet spaced rigid relationship to each other;
- wherein the outer face of at least one of the frames includes measurement indicia for identifying a selected distance on the frames.
A stair support, comprising:
- a first L-shaped member having a tread-supporting section and a riser-supporting section integrally connected to and disposed at a right angle to the tread-supporting section at an intersection point, with pre-formed measurement indicia originating at the intersection point and extending along the tread-supporting section for selecting a desired tread length or extending along the riser-supporting section for selecting a desired riser length, or both;
- a second L-shaped member having a tread-supporting portion and a riser-supporting portion integrally connected to and disposed at a right angle to the tread-supporting portion at an intersection point;
- an anchor block coupled to the first and second members to maintain the members in a spaced configuration with respect to each other.
