Publication number: 20030089066Abstract: The invention disclosed herein is remarkable in its simplicity and promises wide commercial application as the labor costs for construction become increasingly prohibitive. The extraordinary absence of nails, screws, bolts, welds or any other fastening device allows these barriers to compete with many conventional barrier systems, such as those employed for fencing, vehicular trailer beds, removable stages, and scale models or toys of all fabrications mentioned plus many more. In this age time is money and the erection speed this barrier system offers may well revolutionize conventional “post and beam” framing. The invention is specifically aimed at eccentric beam loading where barriers must be economically fabricated to withstand hurricane force winds, earthquake reactions, or liquid concrete pressure in a sub-rigid manner. The Fast-Form System will offer insurers building products that will protect their interests for any and all applications.Type: ApplicationFiled: October 25, 2002Publication date: May 15, 2003Inventor: Thomas P.

Patent number: 6539591Abstract: A construction tool to facilitate tie rod and key plate installation onto concrete forms, primarily comprising a housing and an extraction assembly. The extraction assembly having means to slidably journal generally within the housing. The housing has a movable plate assembly at one end that has a protrusion outwardly extending therefrom. The protrusion is uniquely shaped to mount a key plate thereon. Additionally, the housing has brackets mounted at opposite sides of the movable plate, which provide space for the extraction assembly to mount onto the end of a tie rod. Operationally, a key plate is mounted onto the protrusion, said invention is placed onto the approach side of a concrete form, and an extraction head of the extraction assembly is placed onto the tie rod end and pulled sufficiently to allow placement of the key plate onto an interlocking notch of the tie rod, thus securing the concrete form.Type: GrantFiled: October 19, 2001Date of Patent: April 1, 2003Inventor: Rolando Blanco

Publication number: 20030056462Abstract: A method and apparatus for forming a concrete foundation wall. A trench is opened in the ground and a form is inserted into the trench. The form is made up of a pair of spaced-apart opposing panels, which define a cavity. The panels may be made of a thermal insulating material, which may be extruded foam insulation or, more particularly, extruded polystyrene. The panels may be supported through a combination of J-channels, spreader brackets, connecting members, and a support member. The method further includes backfilling the trench around the form with dirt and pouring concrete into the cavity. The dirt provides support for the form as the concrete is poured.Type: ApplicationFiled: September 21, 2001Publication date: March 27, 2003Inventor: Marc Roy

Patent number: 6474033Abstract: A prefabricated finishing module for the construction of building constructions provided with at least one pair of panels facing one another, bounding a space for the casting of concrete, adapted to be connected to one another and to respective panels of adjacent modules and each bounded by first edges opposite one another and by second edges opposite one another and extending between respective ends of the first edges. The module is characterized in that the first edges of each panel have respective first longitudinal grooves aligned with one another and in that the second edges have respective second longitudinal grooves aligned with one another, intersecting the first grooves and transversely offset with respect to first grooves; the first and second grooves are engaged in use, at least in part, by respective first and second anchors adapted to connect the module to adjacent modules intersecting one another reciprocally.Type: GrantFiled: November 20, 2000Date of Patent: November 5, 2002Assignees: Studio Arch.

Patent number: 6443418Abstract: To provide an ultra thin-type metallic form panel, a form employing the same, and a method for constructing a foundation with which labor in performing operations for constructing a concrete building may be remarkably saved. Form panels 2 are used as a form 1 for constructing a foundation, each panel including a plurality reinforcing projecting lines 5 obtained by bending a metallic plate to extend in longitudinal directions and formed in an aligned manner with intervals being formed in lateral directions, wherein guiding portions for bending 20 are formed at intermediate portions in the longitudinal directions by cutting at least top surfaces and both lateral sides of the respective reinforcing projecting lines 5 in lateral directions and the remaining portions are remained as coupling portions 21.Type: GrantFiled: October 26, 2000Date of Patent: September 3, 2002Inventor: Kozo Itamochi

Patent number: 6361014Abstract: A waler bracket is disclosed for securing a waler to a modular form system having a pair of panels being separated by a filler channel, with the filler channel including a pair of flanges with each flange being joinable to an adjacent panel edge portion. The waler bracket includes an inner portion and an outer portion. The inner portion includes an inner through member disposed parallel to the plane of the panels and perpendicular to the panel edge portions, with the inner through member being sized for insertion between the filler channel flanges and being adapted to receive a fastener. The outer portion is adapted for attachment to the waler. Accordingly, the panels, the filler channel, and the bracket inner portion may be connected to each other using a fastener extending through the inner through member, and the waler may be secured to the bracket outer portion, thereby securing the waler to the panels and thereby permitting the form system to be lifted as a unit.Type: GrantFiled: July 9, 1999Date of Patent: March 26, 2002Assignee: Symons CorporationInventor: Manuel Lopez
