In one embodiment, the connector 28 is axially adjustable such that the first shoe 16 can rotate relative to the first end cap 20. For example, the connector 28 can include threads that engage a threaded bore through the first end cap 20. Accordingly, the connector 28 can be rotated or screwed relative to the first end cap 20 to alter the distance between the first show 16 and the first end cap. In another embodiment, the connector 28 can include teeth or a ratchet adapted to engage a pawl of the brace 12. Alternatively, in another embodiment, the connector 28 is fixed with respect to the first end cap 20. The connector 28 may be constructed of metal, plastic composite, carbon fiber, or other suitable material.

(27) The extension 26 has a length 48 of between about 5 feet and about 30 feet. In one embodiment, the length of the extension 26 is between about 15 feet and about 25 feet. In another embodiment, the extension length 48 is about 20 feet. When interconnected to the body 24, the extension 26 adds between about 5 feet and about 20 feet to a length 58 of the body 24. In one embodiment, the extension 26 adds between about 8 feet and about 12 feet to the length 58 of the body 24. In another embodiment, the extension 26 increases the length 58 of the body 24 by about 10 feet.

(28) In one embodiment, the extension 26 has a diameter of between about 4 inches and about 15 inches. In another embodiment, the exterior diameter of the extension 26 is between about 6 inches and about 11 inches, or about 8.5 inches. The chamber 46 of the extension has an interior diameter that is greater than an exterior diameter of the body 24. In one embodiment, the interior diameter of the chamber is between about 5 inches and about 10 inches, or about 8.75 inches. The second end cap 18 is fixed to the body 24. Optionally, the second end cap 18 can be welded to the body 24. Alternatively, the second end cap 18 can be releasably connected to the body. The second end cap 18 can include a second flange 50 (illustrated in FIGS. 4-5). The second flange 50 is adapted to be positioned within a hollow interior of the body 24. In one embodiment, a connector 30 can fix the second end cap 18 to the body 24. Optionally, the connector 30 can be permanently affixed to the body 24. Additionally, or alternatively, the connector 30 can be a bolt or a pin that extends through an aperture of the body 24 and a corresponding aperture formed through the second flange 50 of the second end cap 18. In one embodiment, two connectors 30 are used to fix the second end cap 18 to the body 24 as generally illustrated in FIG. 5.

(29) Additionally, or alternatively, the second end cap 18 can be configured to threadably engage the body 24. For example, in one embodiment, the second flange 50 can include threads adapted to engage internal threads formed within the body 24. The second end cap 18 may be constructed of a metal, a plastic composite, a carbon fiber, or other suitable materials.

(30) In one embodiment, the second end cap 18 is connected to the second shoe 14 by the adjustment device 22. A receiver 32 can engage with the adjustment device 22 and alter the position of the adjustment device relative to the second end cap 18. The receiver 32 may be aligned with an aperture formed through the end cap 18. In one embodiment, the receiver 32 includes a female threaded connection. The female threads of the receiver 32 can be configured to engage male threads formed on an exterior of the adjustment device 22.

(31) The adjustment device 22 is operably engaged to the receiver 32 and the second end cap 18. The adjustment device 22 can selectively extend into or out of the receiver 32 and through the second end cap 18 to adjust the length 60 of the brace 12. Optionally, the adjustment device 22 is configured to adjust the length 60 of the brace 12 by up to approximately 3 feet.

(32) Referring now to FIGS. 8A-8B, in one embodiment, the receiver 32 is a nut or bolt. The nut 32 can be compressed against the second end cap 18 when a force is applied to the second shoe 14. The nut 32 can threadably engage the adjustment device 22. In this manner, rotating the nut 32 will cause the adjustment device 22 to move into or out of the hollow interior of the body 24 to alter the length 60 of the brace 12 without the need to rotate the second shoe 14 or the body 24.

(33) For example, the nut 32 can be rotated in a first direction to decrease the length of a portion of the adjustment device 22 extending outwardly from the second end cap 18 to shorten the length of the brace 12 as generally illustrated in FIG. 8A. Similarly, rotating the nut 32 in a second direction can increase the portion of the adjustment device 22 extending outwardly from the second end cap 18 to increase the length of the brace as generally shown in FIG. 8B.

(34) In one embodiment, the adjustment device 22 is threaded rod. The threaded rod 22 and the nut 32 facilitate fine adjustment of the length 60 of the brace 12. The adjustment device 22 may be constructed of metal (such as a steel), plastic composite, carbon fiber, or other suitable material.

(35) Optionally, a hydraulic piston can be associated with the adjustment device 22. Pressure can be added to the hydraulic piston to force the adjustment device 22 out of the body 24 through the second end cap 18 and increasing the length of the brace 12 as shown in FIG. 8B. By releasing pressure from the hydraulic piston the adjustment device can withdraw into the body 24 to decrease the brace length as shown in FIG. 8A.

(36) A pump can be used to increase the pressure in the hydraulic piston. In one embodiment, the pump can be powered manually. Additionally, or alternatively, the pump can be powered by a motor. The hydraulic ram may include a valve to release pressure. In one embodiment, the hydraulic piston is positioned within the body 24. Alternatively, the hydraulic piston can be position outside of the body 24.

(37) Referring now to FIG. 8C, additionally, or alternatively, the adjustment device 22A can include a plurality of apertures 23 adapted to receive a pin 34A. The second end cap 18 can rest against the pin 34A when the second end 10 of the brace 12 is lower than the brace first end 8 (as generally illustrated in FIG. 1). In this manner, the length 60 of the brace 12 can be increased by placing the pin 34A through a first one of the apertures 23A which is distal to the second shoe 14. Similarly, a user can shorten the length 60 of the brace 12 by placing the pin 34A through a second one of the apertures 23G formed proximate to the second shoe 14.

(38) The apertures 23 can be formed through the adjustment device 22A and oriented substantially perpendicular to a longitudinal axis of the brace 12. Although seven apertures 23A-23G are illustrated in FIG. 8C, the adjustment device 22A can include any number of apertures.

(39) For example, the adjustment device 22A can optionally include from 2 to 30 apertures 23. The apertures can have any desired spacing. In one embodiment, the apertures 23 have a substantially even spacing.

(40) The second shoe 14 is configured to releasably connect the brace 12 to the ground or a horizontal slab 6. In one embodiment, the second shoe 14 can include an aperture or slot 15 to receive a fixture secured to the ground or horizontal slab 6. The slot 15 can have an open end. Optionally, the slot is oriented approximately perpendicular to a longitudinal axis of the brace 12. Although not illustrated, the first shoe 16 can also include a slot 15.

(41) The second shoe 14 can be pivotally connected to the adjustment device 22. In one embodiment, the second shoe 14 includes a pin 34 which connects the adjustment device 22 to the second shoe 14. The pin 34 allows the adjustment device 22 to pivot from 0° to 180° in relation to the shoe 14.

(42) Alternatively, and referring now to FIG. 9, a helical anchor 52 can be interconnected to the adjustment device 22. The helical anchor 52 is adapted to be driven into the ground 6. For example, the helical anchor 52 can include one or more helical plates 56 welded to a shaft 54. The helical plates 56 generally spiral around portions of the helical anchor. When the helical anchor 52 is rotated, the helical plates 56 can engage the ground 6 and pull the helical anchor into the ground.

(43) In one embodiment, the body 24 of the brace 12 is a rod or cylinder. The body 24 may be referred to as the “inner-pipe” or as the “long-pipe.” In one embodiment, the body 24 is a hollow cylindrical tube constructed of a metal, such as a high-grade steel. The body 24 can be formed of steel plate that is cut and welded into a cylindrical tube. The steel plate can be twisted into the cylindrical tube and the edges of the plate can be welded together. In one embodiment, the body 24 is formed of a thicker piece of steel than the extension 26. For example, in one embodiment the body 24 is formed from steel plate with a thickness of approximately 0.148 inches and having a yield strength of approximately 40 ksi. Alternatively, in another embodiment, the body 24 can be formed of ⅜″×44 ksi steel plate.

(44) The body 24 has a length 58 that can be between about 15 feet and about 70 feet. In one embodiment, the length 58 of the body 24 is between about 50 feet and 55 feet. In another embodiment, the body length 58 is about 52 feet.

(45) The body 24 can have an exterior diameter of between about 3 inches and about 12 inches. In one embodiment, the exterior diameter of the body 24 is between about 6 inches and about 10 inches. In another embodiment, the body exterior diameter is between about 8 inches and about 9 inches.

(46) Referring now to FIG. 4, the brace 12 is shown in a disassembled state with the body 24 and the extension 26 shown separated. The body 24 includes at least one hole or aperture 40 proximate to an end of the body 24. The extension 26 includes at least one aperture 42 that can be aligned with the aperture 40 of the body. The apertures 40, 42 can be used to attach the extension 26 to the body 24 with a connector, such as connector 36, as generally illustrated in FIGS. 2-3. The connector 36 may be a bolt, a dowel, or a pin, that passes through the aperture 42 and the aperture 40. Optionally, one or more of the extension 26 and the body 24 can include a plurality of apertures 42, 44 which can be aligned. In this manner, the length 60 of the brace 12 can be incrementally adjusted. The body 24 can include any number of apertures 40, for example from 2 to 20 apertures 40. Optionally, the extension 26 can include from 2 to 20 apertures 42. In one embodiment, the body 24 and extension 26 can includes the same number, or a different number, of apertures 40, 42, respectively.

(47) Referring now to FIG. 6, in one embodiment, the brace 12 is configured to prevent rotation of the extension 26 relative to the body 24. In this manner, the body apertures 40 can be aligned with the extension apertures 42 to receive a connector 36. In one embodiment, the extension 26 has an alignment feature 27 that engages an alignment feature 29 of the body 24 to prevent rotation of the extension relative to the body. The alignment feature 27 of the extension can extend inwardly from an interior surface of the extension. Similarly, the alignment feature 29 of the body 24 can extend outwardly from an exterior surface of body. The alignment features 27, 29 are configured to contact each other to prevent the relative rotation of the body 26 to the extension 26.

(48) Additionally, or alternatively, in another embodiment the extension 26 can be configured to rotate relative to the body 24 to alter the length of the brace 12. For example, the chamber 46 of the extension 26 can include threads which engage threads formed on an exterior surface of the body 24.

(49) Referring against to FIG. 4, the body 24 can optionally include indicia 43 configured to indicate the amount of the body 24 positioned within the chamber 46 of the extension 26. For example, the indicia 43 can be used to select how far the open end 25 of the body 24 is inserted into the chamber 46 of the extension 26. The indicia 43 can be a line or other mark oriented approximately perpendicular to a longitudinal axis of the body 24 and formed on an exterior surface of the body. In this manner, a user can select a length 60 of the brace 12 by aligning the open end of the extension 26 with one of the lines 43.

(50) Any number of indicia 43 can be formed on the body 24. In one embodiment, the indicia 43 are spaced apart by a predetermined distance. The predetermined distance separated adjacent indicia can from approximately 1 inch to approximately 6 inches.

(51) Referring now to FIG. 5, the body 24 and the extension 26 are shown connected to form the brace 12 with a length 60. In one embodiment, approximately one-half of the length 48 of the extension 26 overlaps the body 24 when connected to form the brace 12. Additionally, or alternatively, the extension 26 can overlap the body 24 by about 10 feet. The length 60 of the brace 12 can be between about 47 feet and about 72 feet. In one embodiment, the brace 12 has a length 60 that is adjustable between about 59 feet and about 65 feet, or between about 61 feet and about 63 feet. In another embodiment, the length 60 of the brace 12 is about 60 feet.

(52) Full size production braces 12 of embodiments of the present invention have been tested in tension and compression to determine their failure loads. The testing determined that the brace 12 including the body 24 and extension 26 has the same load capacity as a brace comprising only the body 24 when assembled as described herein. Accordingly, the additional length provided by the extension 26 to the length 58 of the body 24 does not result in the brace 12 losing any load capacity. The brace 12 with the extension 26 can support a load of at least approximately 16 kips without buckling. Accordingly, the brace 12 can support a load substantially the same as the 52′ brace 2E described in conjunction with FIG. 1. The brace 12 also complies to American Society of Civil Engineers (ASCE) 37-02 (“Design Loads on Structures During Construction”) and ASCE 7-10 (“Minimum Design Loads for Buildings and Other Structures”) regarding basic wind speeds.
