PARTICULATE CONTAINMENT CONTROL FOR STRUCTURED SUPPORT BEAMS
A reusable mobile self-retaining containment barrier shield for structural beams used in bridge construction that provide for a self-sealing adaptable frame support for containment sheeting between support beams. At least two telescopically extensible frame elements adjustably interengage with one another against and between the adjacent support beam openings with entrapment flexible sheeting tarp selectively secured thereto sealing the “end channels” between the beams during reconditioning and painting for retainment of contaminated spent cleaning abrasives.
This application claims the benefit of U.S. Provisional Application No. 62/174,912, filed Jun. 12, 2015.
BACKGROUND OF THE INVENTION1. Field of the Invention
This device relates to environmental containment systems used to limit the spread of contaminated blasting material used in cleaning and preparing structural surfaces during reconditioning.
2. Description of Prior Art
Prior art devices of this type have been directed to onsite construction wherein wood framing is custom cut and assembled to form a custom support frame between the open ends adjacent structural beams used in bridges and the like. Said custom onsite stick built frames are then typically sealed in place with expanding synthetic foam to form a gasket and tarps are attached from the surface forming a containment and the bulk head.
A number of prior art patents illustrate different general platform and sheeting supports to contain and direct spent product and sand and shot blasting with entrained contaminants safe from the environment, see U.S. Pat. Nos. 4,429,764, 4,854,419, 5,011,710, 5,481,832, for example.
SUMMARY OF THE INVENTIONAn interengageable adjustable reusable intermediate bridge beam containment insert system that provides for a universal inter-engageable sections of telescopically extensible adjustable tubular elements that inter-engage with one another and extend to form a containment self-supporting perimeter support frame over which a flexible sheet barrier material is integrally secured.
Referring to
The hereinbefore described extensible tubular assemblies 11 and 12 are selectively and adjustably secured to one another as seen in
Referring now to
Referring now to
It will be noted that the hereinbefore disclosed containment bulkhead 10 for structural support beams can also provide for outer end beam containment applications so as to be used to form an outside end enclosure combination as will be well understood by those skilled in the art.
It will be seen that by adjusting the inter-engaging tubular assemblies 11 and 12 as hereinbefore described that the containment barrier 10 can be easily and quickly adapted to fit into a variety of different openings requiring the containment barrier and thus becomes universally adaptable in a number of onsite work venues.
It will thus be seen that a new and novel containment barrier has been illustrated and described and though it will be apparent to those skilled in the art, the various changes and modifications may be made thereto without departing from the spirit of the invention.
Claims
1. A containment barrier for a bridge supports used in sandblasting operations, said barrier comprising,
- a pair of telescopically extensible tubular assemblies selectively secured together to form a continuous support frame,
- said tubular assemblies comprises,
- a first right angular support element and a second right angular support element, moveably engaged thereon,
- a fixed threaded rod extending from said first right angular support element, adapted for threaded registration with said second right angular support element for adjustable advancement thereto,
- means for adjustably securing said tubular assemblies in aligned orientation to one another,
- and a flexible bulkhead tarp slidably positioned over said so constructed continuous support frame.
2. The containment barrier for bridge supports set forth in claim 1 wherein said threaded rod adapted threaded registration with said right angular support element comprises,
- a rod housing secured to said second right angular support element,
- an adjustment nut and washer on said threaded rod registerable against said rod housing, advancing said housing and said secondary right angular support element along said rod.
3. The containment barrier for bridge support set forth in claim 1 wherein said means for adjustably securing said adjustable telescopically extensible tubular assemblies and aligned end to end orientation to one another comprises,
- insert sections within and extending between said respectable of aligned free ends of said adjustable telescopic extensible tubular assemblies,
- adjustable retaining screws threadably disposed through said aligned free ends engaging said insert therebetween.
4. The containment barrier for bridge supports set forth in claim 1 wherein said flexible bulkhead tarp comprises, an open bottom enclosure extending beyond a corresponding portion of said continuous support frame.
5. The containment barrier for bridge supports set forth in claim 1 wherein auxiliary resilient foam strips are selectively positioned between said continuous support frame and irregular frame engagement surfaces.
