Abstract
A flowable material container comprises an outer container, including a circumferentially extending, flexible fabric sidewall with stiffeners mounted within pockets in the sidewall, and an inner bag. The stiffeners may be removable to permit the support container to be placed in a collapsed, shipping state. A vertical lifting element may be associated with at least one of the inner bag and the outer container. The sidewall may be circumferentially expandable to provide access to the inner bag. The sidewall may also include a door to provide lateral access to the entire interior of the outer container when opened.
Description
- None.
- None.
- Equipment used to hold, carry and dispense concrete at a building site, including concrete trucks and concrete pumps, may be washed or cleaned out soon after use. This washout procedure typically takes place at or close to the job site. In addition, tools and equipment used for a drywall finishing, stucco application and other similar work are typically washed at the worksite. In the last several years the construction industry, and in particular the concrete industry, has seen many changes in the ecological regulations covering the washout procedure to protect groundwater from contamination from waste concrete as well as other groundwater-contaminating materials. New regulations have created additional restrictions and requirements relating to the treatment and disposal of excess material and wastewater. One of the main concerns is the relatively high pH level in concrete waste. The prevention of spilled concrete from contaminating the ground during the operation of a concrete pump or during the discharge of concrete from a concrete truck is also important. Also, contamination from washing groundwater-contaminating materials, such as concrete, from tools and equipment must also be eliminated.
- One method of dealing with this problem is to build small plastic-lined impoundments on site. It was believed that once the water settled and was clear, the water was no longer problem. However, it has become recognized that the wastewater, after settling, may still have an unacceptably high pH. In addition, such impoundments are typically constructed using straw bales; the walls of such impoundments are typically too tall for concrete pumps to be washed out into.
- A first aspect of the invention is directed to a flowable material container comprising an outer container and an inner bag. The outer container comprises a circumferentially extending, flexible fabric sidewall, the sidewall defining an interior and comprising pockets, and stiffeners mounted within the pockets. The stiffeners are preferably removable to permit the support container to be placed in an open, use state and a collapsed, shipping state. A vertical lifting element may be associated with at least one of the inner bag and the outer container. The sidewall may include a door movable between a closed state and an open state to provide lateral access to the entire interior when in the open state.
- A second aspect of the invention is directed to a method for containing a material, the material being at least initially flowable. A flowable material container is placed on a support surface at a chosen location, the flowable material container comprising an inner bag and an outer container, the outer container comprising a circumferentially extending, flexible fabric sidewall and the inner bag comprising an inner, flexible, conformable bag within the outer container. An at least initially flowable material is discharged into the inner bag. At least portions of the inner bag, with the material therein, and the outer container are separated from one another to facilitate removing the inner bag and material therein from the outer container. The settable material may be allowed to set before opening the door in the sidewall.
- A third aspect of the invention is directed to a method for preparing an area for concrete discharge. An outer container, comprising a circumferentially extending, flexible fabric sidewall with pockets, is selected. Stiffeners are placed within at least some of the pockets so to permit the outer container to be placed in an open, use state from a collapsed, shipping state. An inner, flexible, conformable bag is arranged within the interior to create a flowable material container. The flowable material container is positioned at a concrete discharge area for receipt of discharged flowable concrete. The method may further comprise discharging flowable concrete into the inner bag, allowing the flowable concrete to set, lifting the flowable material container together with the material in the inner bag, separating at least portions of the inner bag, with the set concrete therein, and the outer container from one another to facilitate the removing step, and removing the inner bag and set concrete therein from the outer container.

FIG. 7 illustrates an alternative, pan-like embodiment of theouter container 12 ofFIG. 1 . Pan-likeouter container 52 has a relativelyshort sidewall 16. Doors are not needed on this embodiment because the inner bag, not shown, used with this embodiment may be separated fromouter container 52 without the need for such doors. Pan-likeouter container 52 may be used in a manner of a drip pan to catch a relatively small amount of concrete or other waste. In this embodiment stiffeners are typically positioned horizontally and inserted through stiffener access regions 30 created alongcorners 48. -
FIG. 8 is a partial cross-sectional view of a corner of a further alternative embodiment of the outer container ofFIG. 1 . In this embodimentouter container 54 includes asidewall 16 removably secured to a releasable bottom 56. Releasable bottom 56 is similar to the structure ofFIG. 7 and is releasably secured tocircumferential sidewall 16 using, for example,buckle assemblies 58. Other types of attachment structures may also be used. -
FIGS. 9 and 10 show anouter container 60 similar to that ofFIG. 1 but having a drop-down door 62.Door 62 is shown secured in a closed, upright state inFIG. 9 .Door 62 is maintained in the closed state usingfastener material 28 secured to sidewall 16 and the exposed outer ends 64 of strapping 66. Releasingfastener material 28permits door 62 to drop down to the down, open state ofFIG. 10 . -
FIG. 11 showsflowable material container 10 ofFIG. 2 afterinner bag 14 has been at least partially filled with a material and theupper edge 68 of the inner bag has been gathered together and tied off for disposal.Container 10 may be lifted at liftingloops 50 and transported to, for example, a disposal site. One of the advantages of the invention is thatouter container 12 is typically reusable. To permit reuse ofouter container 12,side doors inner bag 14. One way to removeinner bag 14 and its contents fromouter container 12 is to lift the liftingloops 50opposite doors inner bag 14 and its contents to be discharged fromouter container 12. One or more ofstiffeners 24 can then be removed frompockets 22 to facilitate foldingouter container 12 down to a collapsed, shipping configuration. -
Vertical lifting elements 44 have been shown secured to an extending fromouter container 12. However, vertical lifting elements may be provided by, for example, strapping positioned betweenouter container 12 andinner bag 14. In addition, a concrete-embeddable anchor 70, one embodiment being shown inFIG. 12 , may be placed withininner bag 14.Inner bag 14 would then be filled with a settable material, such as concrete, to a depth permitting theupper end 72 ofanchor 70 to extend above the material. After the concrete, or other settable material, has set, the user can lift the material, and typicallyinner bag 14 therewith, by simply engaging upper and 72 and lifting. It will typically be advisable, if not necessary, toopen side doors sidewall 16 to bow outwardly when placed withincontainer 10. The design ofanchor 70 may be changed so long as a portion extends out of the set concrete, or other settable material. Whileanchor 70 preferably has some type of exposed loop or hook to facilitate lifting, it may not be necessary to have one. - Concrete test cylinders are often made during construction. It is important that these concrete test cylinders be properly cured. One way to help ensure that the concrete test cylinders are properly cured is to ensure that they are not subjected to inappropriately high or low temperatures. To provide such an environment,
container 10 may be used with a top or lid 76 shown inFIG. 13 . Lid 76 includes a hingedregion 78 to permit user access to the interior ofcontainer 10 without the need to completely remove the lid. Lid 76 includes a pair ofstiffeners 24 within pockets on each side of hingedregion 78. To enhance the thermal insulation properties ofcontainer 10 with lid 76,stiffeners 24 may be made of honeycomb, structural foam, composite or other materials having good thermal insulation properties. Lid 76 may be loosely placed oncontainer 10 or secured to container using appropriate fasteners, such as hook and loop fastener material, buckles, or latches.Container 10 with lid 76 would be strong enough to allow the concrete test cylinders to be stored, lifted and transported without removal from the container. -
Doors inner bag 14. Access toinner bag 14 can also be provided by providingsidewall 16 with a circumferentiallyexpandable portion 82 as shown inFIGS. 14 and 15 .FIG. 14 illustratesportion 82 in a first, reduced circumference state through the use of areleasable strap 84. InFIG. 15 , strapping 84 has been released to permitsidewall 16 to assume a second, expanded circumference state thereby providing access toinner bag 14.Expandable portion 82 would be particularly useful when lifting the set concrete fromouter container 12 usinganchor 70 or strapping betweeninner bag 14 andouter container 12. The use ofdoors expandable portion 82 are particularly useful for separating at least a portion ofouter container 12 andinner bag 14 from one another when the concrete or other material has set to a solid state. Other structure could be used to provide this separation, which facilitates removal ofinner bag 14 fromouter container 12, when the material has not or does not set up. Such a structure could include sack-like netting betweenouter container 12 andinner bag 14 which upon lifting would squeeze the inner bag to facilitate removal. - The various embodiments of the present intention have been described using hook and
loop fastener material 28 to secure various components together. However, in many cases hook andloop fastener material 28 can be replaced by other fasteners, such as cam buckles, similar to those used on aircraft seat belts, to help lower the cost ofcontainer 10. - Other modification and variation can be made to the disclosed embodiments without departing from the subject of the invention as defined in following claims. For example, the invention can be used as a washout basin for washing tools and equipment used in applying stucco, wallboard mud, and other groundwater-contaminating materials.
