No. 3,316,680 to Jerome A. Chrastek discloses a floor structure fabricated from a plurality of panels in elevated spaced relation to a suitable supporting surface. This patent discloses a leveling means for the elevated floor, but no tie-ins or connections are provided to the main structural components of the building. In fact, the elevated floor is in the form of an addition and forms no basic part of the building structure.

U.S. Pat. No. 3,216,157 to George S. Pinter discloses a concrete structure and process of making same. The principal object of this invention is to support a slab or other elongated member ina generally horizontal position by spaced apart stays above a metallic base. Means are provided to level the slab prior to consolidating its connection to the base by welding or some other bonding operation. This structure is simply a means to level concrete floors and provides no overall tie-in with the main structural components of a building.

U.S. Pat. No. 2,380,692 to F. Gunnison discloses an adjustable building foundation for use with prefabricated or portable buildings. This device utilizes a plurality of enlarged flanged nuts buried in holes about the perimeter of the building. An upstanding rod with a screw-threaded lower end is adjustable relative to each buried nut, and the wooden floor of the building is fixed as by nails, bolts or the like to a flanged top end of each rod.

U .S. Pat. No. 3,066,448 to G. S. Pinter discloses a device very similar to the other Pinter U.S. Pat. No. 3,216,157.

U.S. Pat. No. 3,511,001 to W. R. Morgan, Jr. discloses a resilient leveling means for floors wherein a plurality of vertically adjustable leveling bolts bear on a concrete slab, and generally U-shaped springs carried on said bolts resiliently carry the floor.

BACKGROUND OF THE PRESENT INVENTION The present invention pertains to an adjustable anchor bolt and leveling means whereby all of the main structural components, such as columns, floor slabs, etc., are securely tied together by steel reinforcing members and are adjustable to level and/or align all of the components.

The device of the present invention provides means to securely anchor and level columns relative to a foundation or concrete slab in one simple operation, as well as to level and tie thereto by steel other concrete floor slabs, beams, columns, etc., in a manner whereby a building can be constructed perfectly level with steel reinforcing members continuously tying all of the components together.

One basic form of the invention utilizes anchor bolts cast into a concrete foundation or floor slab with means, pre-cast in a column, for secure, adjustable attachment to said anchor bolts. Steel reinforcing means extend through the column for engagement with a similar anchor bolt and leveling means at the top thereof for attachment to a floor slab. This basic form of the invention is equally applicable in tying other vertical, horizontal or angulated structural components together.

A more sophisticated form of the invention provides anchor bolt blocks wherein all six sides are identical and usable to anchor, level and align all of the main structural components of a building relative to each other, regardless of the angular relation therebetween.

FIG. 2 is a perspective ofa six-sided block utilized in securely attaching and leveling various building structure components in accordance with the present invention;

FIG. 3 is a vertical cross sectional view through a portion of a building structure, illustrating several applications of the block of FIG. 2;

FIG. 4 is a schematic perspective view of a plurality of the blocks of FIG. 3 are connected to form a geodesic dome type of structure; and

FIG. 5 is an enlarged sectional view illustrating a connected, angular relationship of two of the blocks of FIG. 4.

DETAILED DESCRIPTION OF THE DRAWINGS With reference to the drawings inwhich like reference numerals designate like or corresponding parts throughout the several views and with particular reference to FIG. 1, a precast column 10 is illustrated in a leveled, supporting relation between a foundation or. concrete slab 12 and a leveled floor slab 14 thereatop.

A horizontal steel plate 16 which may be perforated, is pre-cast in the foundation or slab l2 and includes a pair of upstanding threaded anchor bolts 18 and 20, welded thereto at 22 adjacent its opposed ends. A horizontal steel plate 24 is likewise pre-cast in the base portion of the column and has fixed thereto or formed integral therewidth a pair of vertically disposed tubes 26 and 28 adjacent to the respective ends of plate 24 in a generally equally spaced, axial relation to the anchor bolts 18 and 20.

Each of the anchor bolts 18 and 20 is threaded at its upper end to engage an internally threaded sleeve 30 or 32 axially disposed through the respective tubes 26 and 28. The threaded sleeve nuts 30 and 32 provide enlarged disc like lower ends 34 and 36 normally disposed in recesses 38 and 40 formed in the bottom of the base 42 of the column 10. Washers 44 and 46 may be disposed between the discs 34 and 36 and the lower ends of the tubes 26 and 28 and recesses 38 and 40. The upper ends 48 and 50 of the internally threaded sleeves 30 and 32 project outwardly of top surfaces 50 and 52 formed by notches 54 and 56 in the column base 42 and are externally screw threaded as at 58 and 60 to receive respective pairs of

nuts

62, 64 and 66, 68.

In use, the sleeve nuts 30 and 32 are threaded onto the anchor bolts 18 and 20 until the disc ends 34 and 36 are seated against the top surface of the foundation or footing 12. The pre-cast column 10 is then seated thereon with the sleeve nuts 30 and 32 being axially disposed through the tubes 26 and 28, and the pairs of

nuts

62, 64 and 66, 68 are threaded onto the external threads 58 and 60 of the respective sleeve nuts 30 and 32.

To raise the left side of the column 10, the nuts 62 and 64 are tightened together as illustrated in FIG. 1

and the lower nut 64 is turned counterclockwisely, threading the sleeve nut 30 upwardly on the anchor bolt 22 resulting in the disc 34 raising said left side. Similar manipulation of the

nuts

66 and 68 raises the right side of the column 10. After either side is raised, the respective pairs of

nuts

62, 64 or 66, 68 are individually tightened against the column 10.

When it becomes necessary to lower either side of the column 10, the left side for example, the nuts 62 and 64 are tightened together as shown and the top nut 64 is then turned clockwisely, threading the sleeve nut downwardly on the anchor bolt 22.

The steel plate 24 in the base 42 of the column is tied to a similar plate 24' pre-cast in the column upper end 70 by a pair of steel rods 72 and 74 in any conventional manner. As illustrated in FIG. 1, the leveling means as above described is duplicated in the upper portion of FIG. 1 to level the pre-cast slab 14 thereatop and will be described only insofar as necessary. Respective pairs of

nuts

62', 64 and 66 and 68 are manipulated on the sleeve nuts 30' and 32' to cause the discs 34' and 36 t to selectively raise or lower either side portion of the slab 14 to level same.

The above description applies to one side of column as illustrated in FIG. 1; however, it is preferable to duplicate the top and bottom leveling means and tie rods 72 and 74 on the back side of the column 10 (not shown) to provide a four-point leveling for both the column 10 and the slab 14.

FIG. 2 illustrates in perspective a hollow anchor bolt block or module 80, preferably constructed of steel and presenting six identical sides 82 through 92. Each side provides an enlarged central opening 94 to permit entry of the hands therethrough during installation, four

wrench slots

96, 98, 100 and 102 about the periphery thereof and four

bolt holes

104, 106, 108 and 110.

In use, the anchor bolt holes 104 through 110 perform the function of the tubes 26 and 28 and any combination of structural components, such as columns, beams, etc., can be anchored and leveled relative to one block 80, utilizing any number of the six faces thereof.

The anchor bolt, leveling means functions exactly the same as described relative to FIG. 1; for example, the column 10 is anchored to and leveled with respect to the bottom corner block 80 (FIG. 3) by anchor bolts 18" and welded to and extending outwardly from the plate 24", cast into the bottom of column 10". The sleeve nuts 30" and 32" are internally, threadably engaged with the screw threaded ends of the anchor bolts 18" and 20" and extend through

respective holes

106 and 108 with their enlarged disc top ends 34" and 36", normally engaged against the outside surface of the side 86. When the respective pairs of nuts 62", 64" and 66", 68" are manipulated in the manner described relative to FIG. 1, the anchor bolts 18" and 20" are selectively threaded into the sleeve nuts 30 and 32" to lower the column 10", or out of said sleeve nuts to raise said column 10''.

It should be understood that four anchor bolts and adjustable sleeve nuts are employed for each connection, and with proper selective adjustment thereof, the column 10" can readily be perfectly aligned or leveled.

The various other connections to the column 10'', beam 116 and slab 14", are adjustable in the manner above described and need no further explanation. However, it should be pointed out that two of the modules or blocks can be interconnected as indicated generally at 120 and 122. In this event, anchor bolts such as 18" and 20" are each threadably engaged between two

sleeve nut assemblies

124 and 126, engaged respectively with the two blocks 80. One of the sleeve nut assemblies, such as 126, is set by the pair of nuts thereon, while the other 124 is adjustable for leveling purposes by the nuts 66" and 68".

Steel rods 72 and 74" interconnect between all of the modules or blocks 80, resulting in a continuous steel tie between all of the main structural components of the building. From two to six columns, beams, slabs, etc., in various combination can be securely interconnected and leveled by a single block 80.

After the pre-cast columns, beams, slabs, and/or footings are tied together with the anchor bolt block, the remaining holes in the exposed sides of the blocks would be used to hold permanent or temporary forms for pouring necessary concrete or may be simply used to secure panels of concrete, wood, plastic or fiberglass.

FIGS. 4 and 5 illustrate the manner in which a plurality of the anchor bolt blocks of FIG. 2 can be angularly attached to form a geodesic or similar type of dome structure. The various blocks are attached together in an angular, horizontal and vertical relationship as best illustrated in FIG. 5.

For this purpose, the opposed end portions of threaded anchor bolts and 132 are engaged in respective pairs of

sleeve nuts

124 and 126 engaged through respective pairs of holes such as 104 and 106 of two blocks 8080. Two of the sleeve nuts 126 in one block 80 may be set by the nuts threaded on the outside thereof while the nuts 66" and 68" threaded on the sleeve nuts 124 carried by the second block may be manipulated in the manner previously described to individually adjust the spacing between the respective ends of the blocks 80-80. In this manner, the angular relationship between respective vertically and horizontally disposed pairs of blades can be adjusted as desired.
