Abstract:
Moisture resistant foundation footing form sections constructed from corrugated plastic are disclosed. Supports for holding sections of reinforcing bar, and connecting the side walls of the form sections are included. Also disclosed are tabs and notches in the side walls for use with stakes to connect adjacent form sections. Form sections are disclosed for constructing a corner in a foundation footing form. Step-down forms are disclosed for constructing a foundation footing form on a construction site having surfaces of different elevations. The form sections can be secured in position with stakes, and leveling devices for leveling the form once it is secured in position are disclosed. The form sections disclosed herein can be reused, but they do not attract insects and therefore they do not have to be removed from finished foundation footings.
Abstract:
The current invention discloses moisture resistant column forms constructed from corrugated plastic. The forms disclosed herein are lightweight and can be easily assembled at a construction site or remote location. The forms can be positioned over pre-placed sections of reinforcing bars, or sections of reinforcing bars can be placed into a form once it is in position. The forms disclosed in the current invention can be easily removed, but they do not attract insects and therefore do not have to be removed from columns after the concrete has dried. The forms disclosed herein have generally square perimeters when they are assembled and put in place, but after concrete is poured into the form, the side walls will undergo uniform deformation/displacement due to the hydrostatic pressure of the concrete and the resulting column will have a generally circular perimeter. A method of using the forms is also disclosed.
Abstract:
Devices for supporting horizontally oriented reinforcing bars in a form for concrete and devices for supporting vertically oriented reinforcing bars are disclosed herein. The devices for supporting horizontally oriented reinforcing bars (horizontal reinforcing bar) engage the side walls of a form, spans the space between the walls, and remains securely in position. The device includes guide members for guiding reinforcing bar sections into a desired position, and members that secure the reinforcing bar in position. The devices for supporting vertically oriented reinforcing bars (vertical reinforcing bar) are used with a generally L-shaped section of reinforcing bar and secured to two parallel sections of horizontal reinforcing bar. The devices can be constructed from any material having properties that make the material satisfactory for use with concrete and provide sufficient strength to support the form side walls against deformation under hydrostatic pressure.
Abstract:
An adjustable bracket is provided for supporting concrete reinforcing bars for use in the construction of concrete structures. In particular, The present invention is an apparatus, system and method for supporting concrete reinforcing bars as used in the construction of concrete structures. In particular, this invention relates to an adjustable support for reinforcement bar, or similar reinforcing members, a plurality of which are disposed within a concrete form. The support is adjustable to a desired length corresponding to the cross-sectional width of the form. The support is mounted across opposing form walls providing a simple, inexpensive and time-saving means of positioning reinforcing bars in an essentially parallel arrangement within the form prior to the form's being filled with liquified concrete. In one embodiment of the present invention, and adjustable support is disclosed having an assembly of interlocking members with one member supportable by one form wall and having multiple holes for reinforcement bar, and another member supportable by an opposing form wall and having multiple retainer segments aligned with the reinforcement bar holes of the first member, whereby the two members are axially positionable and lockable to a desired length of bracket to support transversely mounted reinforcing bars. In an alternate embodiment, an adjustable bracket is formed of two molded members, each of which has multiple holes for reinforcement bar, the first member being supportable from a first by wall and the second member being supportable by an opposing wall, whereby each member is overlapped with the other to be axially positionable and lockable to a desired length of bracket. In another embodiment, an adjustable bracket is formed of two molded members, the first member of which is supportable by one form wall and has multiple holes for reinforcement bar and score marks at regular intervals to allow a worker to selectively and easily break off an undesired excess length of material. The second member is supportable by an opposing form wall and has a recess to receive the broken-off end of the first member, whereby the two members are axially positionable to a desired length of bracket.
Abstract:
A hydraulic tail trailer comprising a main deck having a main tail assembly pivotally connected to the rearward end thereof with the pivotal connection therebetween being located forwardly of the centerline of the rear axle of the trailer suspension system. The location of the hinge between the main deck and the main tail assembly, by being located forwardly of the centerline of the rear axle, provides a main tail having an increased length thereby providing a lower loading angle without increasing the overall length of the trailer. The trailer of this invention also enables the front axles of the trailer suspension system to be moved to multiple spread positions with respect to the rear axle.
Abstract:
A faucet apparatus for mounting on sinks, washbasins and the like, is disclosed comprising automatic water supply shut-off valves that allow quick and easy installation or removal of a faucet head assembly on a faucet base mounted within a sink or similar fixture without the need to manually turn the supply lines off and on. The faucet head is removable from the base, which stays attached to the fixture. The shut-off valves are each comprised of a normally-closed valve assembly, and the faucet head has corresponding actuators that engage and open each valve assembly, enabling water flow to the faucet head as it is installed onto the base. The faucet apparatus further comprises an attachment means for mounting the base within a fixture. An alternate embodiment has a base comprising an additional passage for allowing installation of low-voltage conductors and electrical connections to enable features such as automatic faucet actuation.
