Description
- This application is a continuation-in-part of U.S. patent application Ser. No. 10/964,143 filed Oct. 13, 2004, which is a divisional of U.S. patent application Ser. No. 10/272,698 filed Oct. 16, 2002, now U.S. Pat. No. 6,820,390 dated Nov. 23, 2004, which is a continuation-in-part of U.S. patent application Ser. No. 09/777,400 filed Feb. 6, 2001, now U.S. Pat. No. 6,823,635 dated Nov. 30, 2004.
- The present invention relates to the manufacture of concrete walls used in tilt-up construction. More particularly, the present invention is directed to a spacer support that holds a weldment plate in proper position until the wet concrete sets up.
- In commercial construction, as well as in residential construction where wood is at a premium, builders are increasingly using tilt-up construction, that is, they are pouring concrete walls in forms as they lay on the ground, floor or other surface, and then tilting them up into the desired position after the concrete has cured. One of the features such construction affords is the placement of a weldment plate on one surface of the wall so that structural support beams, and the like, may be welded/secured between adjacent walls. In current practice, the concrete wall is poured and then the weldment plate is “floated” on the top of the wet cement. Since these steel plates are denser than the wet concrete, they tend to sink below the surface. Accordingly, it sometimes becomes necessary to allow the concrete to take a partial set and then attempt to push the weldment plate into the desired position. Neither of these current practices provides effective quality control and the results often are not those desired.
- The device of the present invention comprises a spacer support that engages the support surface on which the concrete wall is poured and a weldment plate holding it in the desired position relative to that surface during the curing of the concrete. The spacer support comprises an elongate body portion having a length substantially equal to the thickness of the concrete wall minus a dimension of the weldment extending in the direction of the thickness of the concrete wall; a surface engaging portion for contacting the surface on which the concrete wall is poured and supporting the weldment in a position appropriately spaced from that surface; means for attaching said body portion to the weldment, wherein the weldment will be maintained in a desired position as wet concrete is poured and sets up. For more details on previous embodiments, see U.S. patent application Ser. No. 10/272,698 filed Oct. 16, 2002, now U.S. Pat. No. 6,820,390 dated Nov. 23, 2004, which is a continuation-in-part of U.S. patent application Ser. No. 09/777,400 filed Feb. 6, 2001, now U.S. Pat. No. 6,823,635 dated Nov. 30, 2004, which are incorporated by reference herein in total.
- Weldment plates take different forms: some are simply rectangular metal plates with two smooth surfaces. Other weldment plates are equipped with protrusions on one surface that improve the adhesion of the plate to the wall enabling greater weight to be suspended therefrom. These protrusions typically take the form of a plurality of Nelson studs welded to the surface of the plate that is to be embedded in the concrete. These studs can have shaft diameters of ¼″, ⅜″, ½″, ⅝″ with head diameters graduated by ¼″ increments between ½″ and 1-¼″. For weldment plates that have no protrusions, the support spacer will have additional length (as compared to those engaging the heads of Nelson studs) and be equipped with a flat head that can be adhered to the nether surface of the weldment plate by an adhesive such as LIQUID NAILS (a registered trademark of Macco). The spacer supports will be used on each weldment plate positioned to provide balance in the wet concrete. The embodiment of support spacer engaging the Nelson stud will have a plurality (three shown) of fingers that grip the head of the stud, the fingers having portions that snap beneath the head and retain the spacer support in position while the concrete sets up. This configuration will be made in a plurality of sizes to accommodate the various sizes of Nelson stud heads.
- More particularly, the invention herein incorporates means for attaching the elongate body portion to the weldment plate projection head and compises a cup-shaped portion configured so that the projection head can slide on top of the upper end planar portion of the elongate body portion into the cup-shaped portion. The device is preferably designed and dimensioned so as to provide a relatively snug fit sufficient to hold the projection head in position. If needed, a shim can be placed to provide for the snug fit if larger devices are used. Holes or apertures may optionally be provided on the side surface of the cup-shaped portion and on its upper planar portion forming the cup-shaped portion. These holes allow for concrete contact surface areas to the head of the stud head.
- The spacer support is preferably made of a material selected from the group consisting of plastic, metal, and powdered metal. The end contacting the support is preferably pointed to minimize the surface treatment needed for the wall and, typically, the wall may simply be painted, papered or given any other conventional treatment, without the tips of the spacer/supports affecting the treatment. The length of the body portion of the spacer support may be adjusted in either of two ways: the surface may be scored at any of a plurality of conventional lengths, and the spacer support cut to the length appropriate for the wall thickness with which it is used, or the spacer support may be made of material suitable for cutting in the field with available cutting snips.
- Various other features, advantages and characteristics of the present invention will become apparent to one of ordinary skill in the art after a reading of the following specification.
- The preferred embodiment(s) of the present invention is/are described in conjunction with the associated drawings in which like features are indicated with like reference numerals and in which:
-
FIG. 1 is a side view conceptual depiction of the present invention shown assembled on a Nelson stud; -
FIG. 2 is an exploded view of the spacer support shown inFIG. 1 ; and -
FIG. 3 is conceptual depiction of the stud extenders in use. - The present invention is a weldment plate spacer support or stud extender, which is generally depicted in
FIGS. 1-3 , and is generally represented by thenumeral 10. The stud extender comprises anelongated body portion 22 having a topplanar portion 28, asurface engaging portion 24, and means 26 for attaching the spacer support toweldment plate 11. In this embodiment,weldment plate 11 includesprojections 15 which may take the form of Nelson studs welded to thesurface 13 ofweldment plate 11 to be embedded in theconcrete 17.Body portion 22 is of a length substantially equal to the thickness “t” of theconcrete wall 18 minus a dimension of theweldment plate 11 extending in a direction of the thickness of theconcrete wall 18. In this case, the dimension of the weldment plate extending in the direction of the thickness ofwall 18 includes the thickness ofplate 12 as well as the length of Nelsonstud 15. Nelson studs come in a plurality of sizes and lengths. Common diameters include ¼″, ⅜″, ½″, ⅝″ with head diameters of ½″, ¾″, 1″ and 1-¼″ respectively. Theheads 16 also vary in depth having lengths of 0.187 inch, 0.281 inch, 0.312 inch, and 0.312 inch, respectively, for the diameters listed here. The length ofbody portion 22 will be designed to position theweldment plate 12 where desired, typically withupper surface 14 flush with thesurface 19 ofwall 18. -
Surface engaging portion 24 preferably comes to a point or taperedportion 25 so as to minimize the amount of weldment spacer support that protrudes onsurface 21. Accordingly, minimal accommodation will be necessary to treat thepoints 25 onwall 18. In fact, it is anticipated that the painting, papering or other treatment providedwall surface 21 will adequately cover thepoints 25. It is preferred that the length ofbody portion 22 will be adjustable. One such means can be the cutting ofbody portion 22 to the desired length to placeweldment plate 12 flush with the designedwall surface 19 onceconcrete 17 is poured. To facilitate this cutting (or breaking),body 22 may be provided withscoring lines 40 at one or more conventional wall thicknesses/stud lengths so thepoint 25 may be maintained. - The material from which weldment plate spacer support is made is selected from the group consisting of plastic, metal, and powdered metal. It is envisioned that a durable, tough plastic material such as nylon or polypropylene, possibly with glass or carbon fiber reinforcement will be suitable for this application and provide the most cost effective means of solving this problem. It is, however, possible that for certain applications, the strength requirements will dictate that the weldment
plate spacer support 10 be manufactured from metal including but not limited to powdered metal. Thespacer support 10 of the present invention could be cast or machined from aluminum, from example. - Means for attaching
body portion 22 toweldment plate 11 comprises a cup-shapedportion 26 configured so that thehead 16 of theweldment plate stud 15 can slide on top of theplanar portion 28 of theelongated body portion 22 into the cup-shapedportion 26. It is dimensioned so as to receive theprojection head 16. Preferably the cup-shapedportion 26 is dimensioned so as to provide a relatively snug fit sufficient to hold thehead 16 of thestud 15 extending downwardly fromweldment plate 12 in position. However, if the vertical dimension of the back orupstanding wall 26 b forming the cup-shapedportion 26 is greater than that of the height of theprojection head 15, then a shim, washer or donut-like piece such as that described in the above-mentioned U.S. Pat. No. 6,820,390 dated Nov. 23, 2004, can be used to make the fit snug. Holes orapertures 26 a may optionally be provided on anupstanding wall 26 b forming a back of the cup-shapedportion 26 and on its upperplanar portion 26c forming the cup-shaped portion. These apertures provide for more concrete contact surface areas to theprojection head 16 ofstud 15. - In use (see
FIG. 3 ), stud extender supports 10 are attached toweldment plate 11 as by the cup-shaped portion in which the projection heads 16 are securely engaged. The length of spacer supports 10 will have been previously adjusted to position thesurface 14 at the desired reference plane with respect toupper surface 19 ofconcrete wall 18. The thusly equippedweldment plate 11 is situated inside concrete forms on surface which may, for example, be a plastic sheeting material, and concrete 17 poured into forms. Weldment plate spacer supports 10hold plates 11 in the desired position while the concrete 17 sets up. When the concrete 17 has properly set, tilt-upwall 18 can be uprighted and secured in position. The smallness ofpoints 25 will have minimal/no effect on the surface treatment required to finish wall surface 2 1. - Various changes, alternatives and modifications will become apparent to one of ordinary skill in the art following a reading of the foregoing specification. It is intended that any such changes, alternatives and modifications as fall within the scope of the appended claims be considered part of the present invention.
