Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention is directed to methods for connecting an item, e.g. a sole plate, board, or piece of wood, to a slab or foundation.

2. Description of Related Art

It is common practice to lay a piece of wood or board on top of a concrete foundation and then to toenail vertical wood stud members to the board. In those areas of the country subject to earthquakes, hurricanes, tornadoes, flood, or tidal action which impose upward forces on the building structure it is standard practice to tie a structure to a concrete foundation. In one commonly used system, threaded bolts are inserted into the concrete, holes are made in a board or mudsill, the upstanding bolts are inserted through the holes and the board or mudsill is fastened to the bolts with threaded nuts and washers.

In other common systems, one piece sheet metal anchors or straps are embedded in concrete and the straps nailed to a board or mudsill.

In another prior art system threaded bolts are used anchored in a foundation and an angled holddown is attached to a bolt at a seat portion and an upper portion is either bolted or nailed to the inside face of a vertical board or wood stud.

In other prior art systems, a strap member is partially embedded in the concrete and then the strap is nailed or bolted to a piece of wood, e.g. to a board or vertical wood stud.

Holddowns of various construction for anchoring studs or posts of framed walls to concrete base have long been known in the art. Examples of such holddowns are disclosed in, for example, U.S. Pat. Nos. 4,199,908; 4,9924,648; and 4,995,206. These patents disclose holddowns that include an anchoring portion that is set in a concrete base and a pair of spaced, upstanding plates provided with a clearance to receive a wall post or studs. Screws, throughbolts, nails or other fasteners secure the studs or posts in position.

The prior art discloses a wide variety of anchor straps, holddowns and connectors; e.g., but not limited to those disclosed in U.S. Pat. Nos. 5,970,677; 5,595,031; 5,930,455; 5,375,384; 5,150,553; 5,092,097; 4,995,206; 4,974,381; 4,924,648; 4,570,403; 4,543,757; 4,530,194; 4,199,908; 4,068,426; 4,067,168; 3,750,360; 1,578,947; 1,172,126; and 887,217—all said patents incorporated fully herein for all purposes.

DETAILED DESCRIPTION OF THE INVENTION

FIG. 1 shows an anchor strap 10 according to the present invention which has a body 12 with two spaced-apart initially co-planar holding portions 14 with a slot, space, opening, or cut 13 between them and two spaced-apart initially co-planar arms 16 with a slot, space, opening or cut 15 between them. Initially the arms 16 are also co-planar with the body 12 and with the holding portions 14. Only one arm may be used or at least one arm.

Holes 18 may be provided in the holding portions 14 as desired to accommodate nails, screws, bolts, staples, rivets, or fasteners used to secure a member (e.g. a board, sill, or sole plate) to the anchor strap 10. Holes 19 may be provided in the arms 16 as desired to facilitate securement of the anchor strap in a slab or foundation, e.g. with concrete hardened within the holes 19.

In certain aspects the anchor strap 10 is made of plastic, composite or metal. In one particular aspect, an anchor strap according to the present invention is made of a single piece of flat galvanized steel.

In certain particular aspects, see e.g. the anchor strap 10a in FIG. 2 (which is like the anchor strap 10 and like numerals indicate like parts), according to the present invention has a small bend or inclined portion 22 which provides a stop for placing the anchor strap against a concrete form 24 and also results in a portion 28 of the anchor strap 10 being lower than a portion 26 of the anchor strap 10 when the anchor strap 10 is placed partially on a concrete form like the concrete form 24. This placement insures that the portion 28 will be at substantially the same height or only slightly lower than a level of concrete or other slab material poured into the form and that the portion of the anchor strap in a form will be correctly located and positioned. Since parts of the anchor strap are substantially level with or only slightly below the level of the top of the concrete form, trowel and/or a trowelling machine can work over the top of the entire slab with no (or almost no) hand trowelling required, producing a smooth slab in a relatively shorter time as compared to one with certain prior art anchor straps. Prior art trowels and trowelling are disclosed, e.g., in U.S. Pat. Nos. 7,108,451; 6,976,805; 6,139,217; 5,406,671; 844,204; and 5,450,648.

The bend portion 22 is optional. An anchor strap according to the present invention, e.g. the anchor strap 10a, FIG. 2, can be attached to the top of a concrete form before concrete is poured with nails, screws, tacks and/or adhesive tape (e.g. tape piece 29).

The arms 16 (or arm is only one is used) are bent away from the body 12 prior to pouring of concrete into the concrete form 24 and multiple arms may be bent at any desired angle to each other. In certain particular aspects this angle ranges between 80 degrees and 110 degrees and, in one particular aspect (e.g. see FIG. 4) is about 90 degrees.

As shown in FIG. 3, upon hardening of concrete into the slab 40, the holding portions 14 are bent into shape for closely accommodating a board or sole plate 50 with a contact fit so that nails (or other fasteners) may be inserted through the holes 18 to secure the plate 50 in place. The holding portions 14 include parts 14a, 14b, and 14c. In use in FIG. 3, the parts 14a are co-planar; the parts 14b are parallel to each other; and the parts 14c are substantially co-planar, so that the plate 50 is held in a tight fit within the holding portions 14 and so that the holding portions 14 conform to the shape of the plate 50. The anchor strap 10a is initially positioned so that the plate 50 will be correctly positioned and, in one particular aspect, so that an outer side 52 of the plate 50 is co-planar with an outer side 42 of the slab 40. The holding portions' parts 14a, 14b are substantially level with a top surface 44 of the slab 40.

Dotted lines 11 in FIG. 2 show an alternative initial position for part of the anchor strap 10a. This part is shown by dotted lines 13 in FIG. 3. FIG. 4 illustrates one version of the final use of an anchor strap 10b (like the anchor straps 10 and 10a, like numerals indicate like parts) which is initially located as indicated by the dotted lines 11 in FIG. 2 with respect to a removable form 25. The arms 16 of the anchor strap 10b are separated at about a 90 degree angle and are embedded and encased in concrete of a slab 43. Holding portions 14h and 14k (like the holding portions 14) hold a sole plate 55. Nails 57 through the holding portions extending into the sole plate 55 secure the sole plate 55 to the anchor strap 10b.

As shown in FIG. 4, it is within the scope of the present invention for ends 14m, 14p of the holding portions 14h, 14k respectively to touch; or, as shown in FIG. 3, for ends of holding portions to be separated by a space. Hardened concrete is in the holes 19 in FIG. 4. The holding portions 14h, 14k (as is true for any holding portions of any anchor strap according to the present invention) may be folded or bent into position around a board or sole plate placed on a flat part of the holding portions which is flat on a top of a slab.

FIG. 5A shows an anchor strap 100 according to the present invention with a body 102, bendable spaced-apart holding portions 114a and 114b, bendable spaced-apart arms 116, and holes 118 in the holding portions 114. The arms 114a, 114b are bendable so that a plate placed thereon (e.g. in certain aspects a 2″×6″ board—e.g. as the sole plate 55, FIG. 4) can be completely encompassed by the arms 114a, 114b. In one particular embodiments, using a 2″×6″ board as a sole plate, the arm 114a is about 9″ long and the arm 114b is about 4.5″ long. With the anchor strap 100 in place, after a concrete form is removed, the two arms 114a, 114b are initially extending horizontally toward the outside of the slab. The arm 114a is then bent 180 degrees to point toward the inside of the slab and the arm 114a is then flat on top of the slab. The plate is placed on top of the slab and covers 5.5″ of the arm 114a. The remainder of the arm 114a is then bent vertically, covering the 1.5″ inside of the plate. The remaining 2″ of the arm 114a is then bent down onto the top of the plate and nailed or screwed in place. The arm 114b is then bent to an upright vertical position and nailed or screwed to the plate's outside. The remainder of the arm 114b—about 3″—is then bent onto the top of the plate and nailed or screwed in place with the plate essentially surrounded by the arms. Optionally, the arm is deleted and the remaining single arm is sufficiently long to permit securement to all sides of a sole plate or is sufficiently long to substantially encompass a sole plate.

FIG. 5B is a side view showing the anchor strap 100 held by a tack 105 to a concrete form 124 into which concrete for a slab is to be poured (to the right of the form in FIG. 5B). Dotted lines show the arms 116 separated from each other. A dotted line 111 shows a level to which concrete is to be poured into the form 124.
