  • Patent number: 6270052
    Abstract: A mold is provided for forming a concrete column having at least one recess formed therein, as molded. The mold includes a tubular housing having an inner surface and a recess form having an inner and an outer surface. The recess form is mountable in the housing at a desired location on the inner surface of the mold housing. The recess form is preferably generally a ring The ring's outer surface corresponds to the shape of the housing's inner surface so that, when the ring is mounted in the housing, there are substantially no gaps between the outer surface of the ring and the inner surface of the housing. The ring has a slice through it, so that the ring may be expanded and pried out of the groove or recess molded in the column once the cement has set. Preferably, the slice is off-set from a radial line drawn through the ring. The ring is secured in place in the mold using screws.

  • Patent number: 6263629
    Abstract: A reinforcing grid which advantageously includes fibers of both a first type and a second type is provided. The first type of fibers have a strength sufficient to reinforce the hardenable structural material, such as concrete, after hardening. The first type of fibers also have a higher resistance to degradation in the hardenable material than the second type of fibers. As such, the first type of fibers will continue to reinforce the hardened material in the event the fibers of the second type become corroded in the hardened material. Consequently, a less expensive type of fiber can be used as the second type of fiber and can corrode in the hardenable material without concern for the strength of the hardened structural product. According to one embodiment, the first type of fibers comprises carbon fibers and the second type of fibers comprises glass fibers.

  • Patent number: 6233876
    Abstract: A pivoting gutter assembly is disclosed, in which the gutter can be, during summer months, put into the horizontal collecting position to receive rainwater from the roof and to direct it to a down-spout. For the winter months and or maintenance, the gutters are swung-out to downwards vertical position below the roof cornice thus being protected from damage. The gutter system includes hangers attached to the roof, the hangers each having a bearing. A shaft is inserted into the bearing and the gutter is fixed to the shaft. The system provides for special hangers assuring the correct pitch of the gutters. Also, it contains a down-spout for location above a fixed downward collector for rainwater, thus permitting the gutters to be pivoted from horizontal to vertical position without the need to disconnect the down-spout.
