Parent Case Info
This application is a continuation-in-part application of application Ser. No. 360,346 filed Mar. 22, 1982 and now abandoned.
My new and novel process for constructing a compact concrete member derives both its novelty and vast scope of usefulness from the process means itself and also from the inherent qualities of the new and novel materials utilized in performing the new process. The concrete members mentioned in the above paragraph are intended to be directed chiefly to long compact concrete beams. Although with reservation of the knowledge that my process can be directed to constructing other compact concrete members such as columns piles, street curbs, walls and the like, compact beams will be conveniently utilized as examples.
Since it is expedient to select one common well know species of concrete member as an example in describing and explaining my invention it should be understood that my invention has a broader scope than the chosen example illustrates.
The basic first object of my invention is to reduce the cost of constructing long compact concrete members such as beams by drastically reducing their forming costs by reducing both form construction labor and material costs. My new process uses form materials cheaper than those materials presently used. My new process requires very few junctures between interconnecting form elements; whereas present day form construction requires a multitude of junctures between interconnecting form parts. Any juncture between form parts required in my process is made by a quick cheap manual operation requiring no special skills or tools.
The basic first object of my invention is further enhanced since my process uses a reusable partially suspended horizontal hybrid sling mold, which mold is easily and quickly stripped away from a concrete first member cast within the hybrid sling mold, and thereafter requires a minimal amount of labor to return the mold to its original condition in which again a second concere member can again be formed.
A second important object of my invention is possible because of the inherent qualities of the materials used in my new process. This second object of my invention is to improve the curing environment for concrete members by depositing fluid concrete into an impervious elongated partially suspended horizontal hybrid sling, wherein the thus confined fluid concrete is isolated from contact with the atmosphere and weather. This confinement will produce a desirable longer concrete time setting interval with resulting higher strength being imparted to the concrete.
The basic second object of my invention is further enhanced since my process uses an impervious elongated partially suspended horizontal hybrid sling with an under loop support as a mold, now concrete members such as concrete beams can be constructed out-of-doors because the impervious pliable sheet construction of the mold will protect the confined fluid concrete from the weather such as wind and rain, with a simple expedience of covering only the top of the confined concrete.
The basic second object of my invention is further enhanced since my process uses an impervious elongated partially suspended horizontal sling with an under loop support as a mold. This sling because of its impervious nature can be placed in water saturated soil or even below the ground water level or below the top surface of a body of water and thereafter filled with fluid concrete 6 which will be isolated from the water by the impervious mold. This inherent quality of the material used in my new process expands the environment conditions under which my process can be utilized.
A basic third object of my invention is to utilize my process as a means for constructing longitudinal compact concrete beams and similar members suitable for exterior use because of being provided with an impervious casing protection from wind, rain and snow. Such members or beams cannot be considered as new beams but can only be considered as members or beams having acquired new qualities because of the process by which they are made.
In summation my new process provides for more economical construction for concrete members, of higher strength because of improved curing environment, constructed under both favorable and adverse environmental situations, in reusable molds, while the member itself is suitable for either interior or exterior use, while also being adaptable for precast, poured in place or a combination of precast and poured in place construction.
Other objects and advantages of my invention will be apparent from the following description taken in conjunction with the accompanying drawings wherein like parts are referred to by like reference characters and in which like reference characters refer to like parts: and wherein:
