摘要:
A tubular passage for poured concrete decks has an intumescent tube held in a two-part, clamshell base by a bottom clip. A first tube engages the base's top to clamp a funnel shaped, diaphragm seal to the base. The first tube has spaced, radially extending, parallel ridges at predetermined distances from the base. Longitudinal channels separate the ridges. An extension tube has inward extending lugs passing along the channels to engage various ridges when rotated to fix the passage length. The extension engages the base bottom for corrugated deck supports. A cap with repositionable, locating filaments closes either tube.

A tubular passage for poured concrete decks has an intumescent tube held in a two-part, clamshell base. First and second, spaced apart, funnel shaped, diaphragm seals are connected to a first tubular passage or an adjustable length tubular extension. A cap for closing either tube has an inclined outer surface to form a beveled entrance to the passage in the concrete. An aerator box may be connected to the base. Hinged ends on the base allow the shape and length of support to be altered.

An expansion tank is fastened to a support using a bracket with a U-shaped cross-section formed by a back and two sidewalls. The edges of the sidewalls each have a notch mating with a weld bead on the tank. Fasteners hold the back of the bracket to the support. First and second hose clamps pass through the sidewalls by the back to encircle the tank and clamp it to the edges of the sidewall when the hose clamps are tightened.

A support bracket is provided for use with a fixture for mounting a water closet connected to a water conduit of radius R. The fixture has a plurality of bolts at predetermined locations to which the bracket is mounted during use of the bracket. The support bracket has an elongated member with a longitudinal axis. A first end of the elongated member has at least one aperture sized and located therein to allow the bracket to be fastened to the bolts on the fixture during use of the bracket. A distal end of the bracket has a shaped opening therein. The shaped opening is formed of overlapping circles, resulting in a hole with circular ends of a radius of about R. The shaped opening has two opposing sides each with a cycloid shape and having opposing cusps of the cycloid shape aligned to define at least two circular openings of a radius of about R. The openings are centered on a straight line perpendicular to the longitudinal axis. The shaped opening can be formed in the bracket, or formed in an insert placed in a hole in the bracket.

An plumbing pipe locator and support is provided for fixing plumbing pipes in position relative to studs in a building. The pipe locator and support comprises an elongated supporting strap having upper and lower sides extending along opposing sides of a longitudinal axis. A first plurality of longitudinally aligned, larger pipe openings are interspersed with a second plurality of smaller, aligned fastener openings that extend into ends of the strap. The upper and lower sides undulate to provide a substantially uniform width between first holes and the adjacent sides and the second holes and the adjacent sides. This undulating surface can provide a strap using less material, with reduced manufacturing time, and a strap that can bend without forming creases or stress fractures.

A plumbing strap is fastened to a building. A tubular insert is placed through a hole in a strap with posts on the tubular insert aligning with cut-outs in the strap to restrict rotation of the tubular insert relative to the strap. A flange on one end of the tubular insert abuts the strap to restrict longitudinal motion of the tubular insert. Latches on the tubular insert extend through the hole in the strap to engage the side of the strap opposite the flange and further restrict longitudinal movement of the tubular insert. A collar is placed over the tubular insert and a pipe extends through the tubular insert and collar. The tubular insert has a base adjacent the flange and a skirt distal from the flange. Longitudinal slits in the base and skirt define resilient members in the base and in the skirt that extend in opposing directions, but that can move inward. The collar screws onto the tubular insert causing abutting surfaces on the collar and on the resilient members to force the resilient members inward to grip the pipe and restrain longitudinal and rotational movement of the pipe relative to the tubular insert and strap.
