BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a grout injecting/structure anchoring system and more particularly pertains to solidifying a structure by supporting it from bedrock and filling any subterranean voids which would otherwise cause structural instability.

2. Description of the Prior Art

The use of structural supports and stabilizers is known in the prior art. More specifically, structural supports and stabilizers previously devised and utilized for the purpose of suporting and stabilizing structures through known methods and apparatuses are known to consist basically of familiar, expected, and obvious structural configurations, notwithstanding the myriad of designs encompassed by the crowded prior art which has been developed for the fulfillment of countless objectives and requirements.

While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not describe a grout injecting/structure anchoring system that allows solidifying a structure by supporting it from bedrock and filling any subterranean voids which would otherwise cause structural instability.

In this respect, the grout injecting/structure anchoring system according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in doing so provides an apparatus primarily developed for the purpose of solidifying a structure by supporting it from bedrock and filling any subterranean voids which would otherwise cause structural instability.

Therefore, it can be appreciated that there exists a continuing need for a new and improved grout injecting/structure anchoring system which can be used for solidifying a structure by supporting it from bedrock and filling any subterranean voids which would otherwise cause structural instability. In this regard, the present invention substantially fulfills this need.

SUMMARY OF THE INVENTION

In view of the foregoing disadvantages inherent in the known types of structural supports and stabilizers now present in the prior art, the present invention provides an improved grout injecting/structure anchoring system. As such, the general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new and improved grout injecting/structure anchoring system and method which has all the advantages of the prior art and none of the disadvantages.

To attain this, the present invention essentially comprises a structure, such as a house on a foundation. The structure is susceptible to instability. The instability is due to any subterranean voids. The structure has a foundation. The foundation is positionable on soil over bedrock.

A hollow cylindrical supportive tube is provided next. The supportive tube has a first inner diameter. The supportive tube is adapted to be inserted into soil adjacent to the foundation of the structure and through any subterranean void. The supportive tube has a closed bottom end. The closed bottom end is provided with a cap. The closed bottom end is firmly abutted to bedrock. The supportive tube has an open top end. The open top end is positioned adjacent to the foundation of the structure. The supportive tube further has a linear body between the top end and the bottom end. A plurality of equally spaced circular apertures is provided along the length of the linear body and around its circumference.

A supplemental tube is slidably positioned within the grout tube.

Further provided is an L-shaped support bracket. The support bracket is adapted to be securely placed under a foundation of a structure. The support bracket has a weight bearing horizontal portion. The weight bearing horizontal portion is adapted to support the foundation. The support bracket also has an aligning vertical portion. The aligning vertical portion has a pair of apertures. The apertures have horizontal bolts. The bolts are adapted to couple the support bracket to the foundation. The support bracket has adjusting elements. The adjusting elements include vertically oriented internally threaded sleeves. The adjusting elements further include a vertically oriented unthreaded sleeve. A cross brace and vertical bolts are provided. Each bolt has an upper nut. The support bracket is adapted to hold the foundation at a level desired by a user.

Provided last is a grout dispensing unit. The grout dispensing unit is coupled to the upper end of the filling tube and is for dispensing grout through the apertures of the tube beginning adjacent to the lower end. This allows grout to pass through the apertures of the tube and fill subterranean voids. This filling of the tube and the subterranean void thereby function to solidify the supportive tube. This further produces a massive anchoring flange of the filled subterranean void and is coupled to the supportive tube to add further support to the building structure.

It is therefore an object of the present invention to provide a new and improved grout injecting/structure anchoring system which has all of the advantages of the prior art structural supports and stabilizers and none of the disadvantages.

It is another object of the present invention to provide a new and improved grout injecting/structure anchoring system which may be easily and efficiently manufactured and marketed.

It is further an object of the present invention to provide a new and improved grout injecting/structure anchoring system which is of durable and reliable constructions.

An even further object of the present invention is to provide a new and improved grout injecting/structure anchoring system which is susceptible of a low cost of manufacture with regard to both materials and labor, and which accordingly is then susceptible of low prices of sale to the consuming public, thereby making such grout injecting/structure anchoring system economically available to the buying public.

Even still another object of the present invention is to provide a grout injecting/structure anchoring system for solidifying a structure by supporting it from bedrock and filling any subterranean voids which would otherwise cause structural instability.

Lastly, it is an object of the present invention to provide a new and improved grout injecting/structure anchoring system. The system has a support bracket with a horizontal portion and a pair of threaded recesses and a sleeve there between. A grout tube has a plurality of apertures along its length. A lower cross brace is positioned above the sleeve and grout tube with unthreaded holes axially aligned with the threaded recesses of the support bracket. The lower cross brace has associated there with threaded cylinders with lower ends coupled to the threaded recesses and upper ends extending through the unthreaded holes. Nuts are received by the upper ends of the threaded cylinders above the lower cross brace. The nuts are adapted to be rotated for raising the support bracket.

DESCRIPTION OF THE PREFERRED EMBODIMENT

With reference now to the drawings, and in particular toFIG. 1thereof, the preferred embodiment of the new and improved grout injecting/structure anchoring system embodying the principles and concepts of the present invention and generally designated by the reference numeral10will be described.

The present invention, the grout injecting/structure anchoring system10is comprised of a plurality of components. Such components in their broadest context include a structure, a hollow cylindrical supportive tube, a bracket, and a hollow cylindrical filling tube. Such components are individually configured and correlated with respect to each other so as to attain the desired objective.

First provided is a structure12, such as a house14on a foundation16. The structure is susceptible to instability. The instability is due to any subterranean voids18. The structure has a foundation16. The foundation is positionable on soil20over bedrock22.

A hollow cylindrical supportive tube24is provided next. The supportive tube has a first inner diameter. The supportive tube is adapted to be inserted into soil adjacent to the foundation of the structure and through any subterranean void. The supportive tube has a closed bottom end26. The closed bottom end is provided with a cap. The closed bottom end is firmly abutted to bedrock. The supportive tube has an open top end28. The open top end is positioned adjacent to the foundation of the structure. The supportive tube further has a linear body30between the top end and the bottom end. A plurality of equally spaced circular apertures32is provided along the length of the linear body and around its circumference.

Further provided is an L-shaped support bracket34. The support bracket is adapted to be securely placed under a foundation of a structure. The support bracket has a weight bearing horizontal portion36. The weight bearing horizontal portion is adapted to support the foundation. The support bracket also has an aligning vertical portion38. The aligning vertical portion has a pair of apertures40. The apertures have horizontal bolts42. The bolts are adapted to couple the support bracket to the foundation. The support bracket has adjusting elements. The adjusting elements include vertically oriented internally threaded sleeves44. The adjusting elements further include a vertically oriented unthreaded sleeve46. A cross brace48and vertical bolts50are provided. Each bolt has an upper nut52. The support bracket is adapted to hold the foundation at a level desired by a user.

A hollow supplemental tube54is slidably positioned within the grout tube. The supplemental tune is imperforate and has a lower end56and an upper end58. By raising the supplemental tube while pumping grout, the filling of voids adjacent to the lower regions prior to the filling of voids adjacent to the upper regions is insured.

Provided last is a pressurized grout dispensing unit60. The grout dispensing unit is coupled to the upper end of the tube for dispensing grout62through the tube beginning adjacent to the lower end of the tube. The lower end of the tube is adjacent to the bedrock. Grout is thus allowed to pass through the apertures of the supportive tube and fill any subterranean void. This filling of the tube and subterranean void thereby function to solidify the supportive tube. This further produces a massive anchoring flange of the filled subterranean void and is coupled to the supportive tube to add further support to the building structure.

An alternate embodiment of the invention is illustrated inFIGS. 7 through 11. In such embodiment, there is disclosed a grout injecting/structure anchoring system100for solidifying a structure by supporting it from bedrock and filling any subterranean voids which would otherwise cause structural instability. The system comprises, in combination, a structure102susceptible to instability due to any subterranean voids. The structure has a foundation104positionable on soil over bedrock. An L-shaped support bracket106is adapted to be securely placed under a foundation of a structure with a weight bearing horizontal portion108adapted to support the foundation and an aligning vertical portion110. The aligning vertical portion has a pair of vertically oriented internally threaded recesses112and a vertically oriented unthreaded short sleeve114there between. The short sleeve has laterally extending vertical wings116. The short sleeve also has an axial length with an upper end and a lower end and an internal diameter.

An intermediate guide tube118has an axial length greater than the axial length of the short sleeve. The guide tube has an internal diameter and an external diameter slightly less than the internal diameter of the short sleeve. The guide tube has a lower end and an upper end with a radial projection120there adjacent. As such, the guide tube may be slidably received within the short sleeve from its upper end but be limited in its downward movement by the projection contacting the upper end of the short sleeve.

A hollow cylindrical supportive grout tube122has an axial length greater than the axial length of the guide tube. The grout tube has an internal diameter and an external diameter slightly less than the internal diameter of the guide tube. The grout tube has a closed lower end and an open upper end. As such, the grout tube may be slidably received within the guide tube. The grout tube further has a linear body124between its upper and lower ends and with a plurality of equally spaced circular apertures126along the length of the linear body and around its circumference.

A lower cross brace128is positioned above the short sleeve and guide tube and grout tube with unthreaded holes130axially aligned with the threaded recesses of the support bracket. The lower cross brace has associated there with threaded cylinders132with lower ends coupled to the threaded recesses and upper ends extending through the unthreaded holes. Nuts134are received by the upper ends of the threaded cylinders above the lower cross brace. The nuts are adapted to be rotated for raising the foundation and structure. The lower cross brace also has a central opening136for the flow of grout there through. It also has an upwardly extending collar138.

A pressurized grout dispensing unit140has a horizontal section142and a vertical coupling section144with a lower end146. It is adapted to releasably coupled to the upwardly extending collar of the lower cross brace.

Securement components include an upper cross brace148receiving at the upper end of the vertical coupling section with two laterally spaced unthreaded bores. An intermediate cross brace150is received at the lower end of the vertical coupling section with two laterally spaced threaded bores axially aligned with the unthreaded bores of the upper cross brace. Two elongated threaded rods152are coupled to the threaded bores and extend upwardly through the unthreaded bores. Nuts154are above the upper cross brace to secure the vertical coupling section to the collar of the lower cross brace.

The collar of the lower cross brace is coupled to the intermediate cross brace so as to preclude upward movement of the intermediate cross brace. The upper cross brace is coupled to an enlargement of the vertical coupling section so as to preclude downward movement of the upper cross brace with respect to the enlargement. As such, tightening of the nuts will increase the seal between the lower end of the dispensing unit onto the lower cross brace and grout tube.

The system is adapted to dispense grout thereby allowing grout to pass through the apertures of the grout tube and fill any subterranean voids. This filling of the tube and subterranean voids thereby functions to solidify the grout tube and produce a massive anchoring flange of the filled subterranean void which is coupled to the grout tube to thereby add further support to the building structure.
