Abstract: A pipe support may include a body. The body may include a first side. The first side may include a channel defined along a length of the body. The body may further include a second side opposite the first side. The second side may include a first planar surface. The body may further include a third side. The third side may include a concave surface defined along the length of the body. The body may further include a fourth side opposite the third side. The fourth side may include a second planar surface.

Abstract: A trailer jack support apparatus configured to support trailer hitches includes a monolithic block having six sides with the trailer jack support being in the shape of a square frustrum or trapezoid. The top of the trailer jack support includes a number of protrusions which extend from the trailer jack support. Further, the top side has a recess and a void located at the bottom of the recess. In addition, the bottom of the trailer jack support includes numerous recesses defined therein and may engage with the protrusions extending from the top of a second trailer jack support.

Abstract: A stair stringer may include a body. The body may include a horizontal arm, a center angled portion coupled to the horizontal arm, and a vertical arm coupled to the center angled portion. The stair stringer may also include a first appendage coupled to a first edge of the horizontal arm, a second appendage coupled to a second edge of the horizontal arm, a third appendage coupled to a third edge of the vertical arm, and a fourth appendage coupled to a fourth edge of the vertical arm. The fourth edge may be adjacent the third edge. The first appendage, the second appendage, and the third appendage are parallel with respect to one another. A stairway system may include a first stair stringer and a second stair stringer. The second stair stringer may be an architectural chiral with respect to the first stair stringer.

Abstract: A roof top structure support has a flat bottom rigid base to be positioned on a roof and spread the load supported by the support substantially evenly over the surface of the base in contact with the roof. A tower rises from the base and includes a slot across the top thereof and a bore therein extending downwardly from the bottom of the slot and adapted to receive a threaded rod therein. The slot in the top of the tower is sized to receive a strut therein. A bolt extending through the strut and into the bore secures the strut to the support. Struts and other structures can be supported above the tower and slot by threaded rod such as “all thread” screwed into and extending from the bore.

Abstract: A device or apparatus that receives and supports a pipe, especially a pipe exposed on a horizontal surface like a roof. The device has a base with a substantially flat bottom for resting on the horizontal surface and a supporting structure with a recess rising from the base to support the pipe. Positioning means are provided in the bottom of the recess to position and center the pipe within the recess. Such a device maximizes the sliding ability of the pipe and minimize erosion of the recess since the pipe rarely abuts the walls of the recess.

Abstract: A roof top pipe support includes a base having a substantially flat bottom to rest on the roof. At least one, and preferably a pair of raised portions provide a pair of stud-receiving holes in the base to receive and direct studs, preferably threaded studs, upwardly from the base. The raised portion also can receive and support a pipe supporting roller. A pipe support such as a pipe supporting roller or a strut also can extend between upwardly extending studs and be adjustably secured to the studs so the height of the pipe support can be adjusted. Either pipe support can be used depending upon conditions and the height of the support needed.

Abstract: A pipe-supporting device adapted to receive and support an exposed pipe on a building roof has a base with a substantially flat bottom for resting on a roof and an upwardly tapered structure secured on and rising from the base to provide an upwardly divergent, substantially V recess having divergent line contacts for receiving the pipe and supporting it above the base. The structure is configured to distribute the weight of the supported pipe substantially equally over the flat area of the base in contact with the roof, and the single line contacts of the V provide this substantially equal distribution of weight regardless of whether the roof is flat or sloped, or regardless of whether the pipe being supported is parallel to the roof or sloped with respect to the roof. Further, the line contacts provide a minimum of resistance to pipe movement so that pipes can easily slide on the device when they expand and contract.

Abstract: A pipe-supporting device adapted to receive and support an exposed pipe on a roof has a substantially flat bottom for resting on the roof and an upwardly tapered structure secured on and rising from the base to provide a pipe positioning and supporting structure which substantially equally distributes the weight of the supported pipe over the area of the base in contact with the roof. The pipe positioning and supporting structure has a pocket for positioning a pipe therein and the pipe is supported in the pocket by at least one roller positioned in at least one receiving trough. As the pipe expands or contracts, it rides on the roller which rotates within the trough.
