Facer beam barrier system

Abstract

This invention expands Nelson's Sub-Rigid Fast-Form Barrier System that it was originally a part of. The system disclosed herein is simple to manufacture and simple to use and promises wide commercial application as the labor costs for concrete 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 and any concrete form system on the market today. The invention addresses eccentric beam loading where barriers must be economically fabricated to withstand liquid concrete pressure in a sub-rigid manner. While providing a lightweight beam with heavy weight strength it is also a goal of this invention to provide a form system that is self-contained, meaning that all fasteners to construct the barrier, ties that hold form barriers together, staging needed to erect the barriers, bolts used to plumb the barriers and brackets available to hoist the barriers are all integral parts of this invention. Another goal disclosed herein are barriers for concrete formwork that are made up of ninety percent standard building products found in any locality in the world. This barrier invention offers rapid erection time that can be accomplished by unskilled labor and result in a quality construction.

No. 10 / 281,374 this alternative designated as species “B” was disclosed in that application submitted Sep. 19, 2000. Species “B” is also a continuation in part of application Ser. No. 08 / 082,570 filed Jun. 6, 1993 in the U.S. Patent and Trademark Office, now abandoned.FIELD OF THE INVENTION [0002] This invention advances the joining of standard building materials for manufacturing mass produced, efficient, concrete form barriers. The barrier application herein will also serve in a wide variety of uses other than formwork [0003] The inventor has many years experience in concrete form design as well as, managing general construction. [0004] Formwork must be assembled quickly in a rigid or sub-rigid composition and maintained in a pre-engineered and static fabrication during concrete placement and subsequently dismantled and stockpiled for f...

Benefits of technology

[0035] The Facer Beam Barrier System is advancement in barriers, for the purpose of reducing man-hours in barrier installations. When fixed costs reduce variable cost, and when fixed cost is not significantly increased while variable costs are dramatically decreased, an economical advantage for the average consumer results.

Problems solved by technology

Bowden teaches a method of extending transverse sub-members in repetition with the ability to overlap and stabilize a plurality of collateral vertical wales, he does not teach a method of ease and efficiency for extending his materials collaterally in a vertical direction.

Bowdens system does not complete formwork application and removal with the ease, versatility, and competence of the facer beam system claimed herein.

Bowden and Chapman both lack the ability to remove plywood modules, or to remove subordinate beams with ease.

Menchetti fails to recognize a method of overlapping subordinate beam members and he does not reveal a method of incorporating the main member or super-ordinate beam as a facer beam.

Menchetti's art does not address issues related to formwork such as self-contained; staging brackets, beam connections, lifting eyes and self contained fastening systems (his fastening system is applied to each facer panel and is not a function of the main beam member).

These large companies control the market and they shape the market to require their rental products and most of their rental products do not integrate with the competition.
