Basement wall recovery system method and apparatus

Abstract

The basement wall recovery system method and apparatus of this invention includes push plate(s), pulling post(s), pulling rod(s), backing plate(s) and a method to apply a pulling force on the pulling rods. The earth is excavated from the wall to be repaired. Based upon the length of the wall, a number of pulling posts are vertically positioned at spaced intervals along the wall. The lower end of the pulling posts generally rest upon the footing of the building. The top of each of the pulling posts rest up against an outer surface of one or two push plates. The push plates are horizontally positioned against the buildings outside wall near the bottom of the wall where it contacts the top of the basement wall to be repaired and generally aligned with the buildings floor joists. The pulling rods are inserted through openings in the pulling posts and through holes bored in the basement wall. A backing plate is attached to the inside end of the pulling post and against the inside of the basement wall to be repaired. The pulling devices are installed on the outer end of the pulling rods extending through the pulling posts. The pulling devices are operated in a predetermined pattern thereby pulling the wall outward and returning the wall to its original plume position.

1 . A basement wall recovery system comprising: 
 one or more push plate(s), each push plate being a sturdy plate, generally rectangular in shape, positionable along a bottom edge and against an outside wall on a building just above the basement wall to be recovered;    one or more pulling post(s), each of the pulling post(s) being a sturdy post, with one or more bore(s) through the pulling post, and having a height to allow the pulling post to extend upward from a footing on the building to a position to at least the position of the push plate(s), the pulling post(s) being positioned vertically with a bottom end against the footing and an upper end resting against the push plate(s), the pulling posts, if more than one is being used, being positioned at spaced intervals along the length of the basement wall being recovered, the number being determined by the length of the basement wall being recovered;    one or more pulling rod(s), each of the pulling rods having a length to enable each pulling rod to extend through a hole bored through the basement wall to be recovered and extending through one of the bores in the pulling posts, one or more pulling rods being used as determined by the length and size of the wall to be repaired;    one or more backing plate(s), each of the backing plates being positioned on an inside surface of the basement wall to be recovered, and each backing plate(s) being secured to the inside end of a pulling rod(s), the backing plate(s) spread or distributing a pulling force over an area, and preventing the pulling rod from being pulled through the basement wall; and    one or more pulling means, the pulling means attachable to the outer end of the pulling rod(s) extending outward from the pulling post(s), the pulling means applying a pulling force to the pulling rod(s)and distributing the pulling force along the pulling post to the push plate above and to the footing below, thereby pulling the bowed and damage wall outward as the pulling force is applied to return the basement wall to a plume position.    
   
   
       2 . The basement wall recovery system as set forth in  claim 1  in which the push plate further comprises a positioner, said positioner being at a center location on an outer surface of the push plate for receiving and holding a top end of the pulling posts.  
   
   
       3 . The basement wall recovery system as set forth in  claim 2  in which the positioner comprises braces, the braces being attached to an outer surface of the push plate in a spaced relationship for positioning the pulling posts between the braces, and the braces extending to outer ends of the push plate, the braces preventing the push plates from bowing when a pulling force is applied.  
   
   
       4 . The basement wall recovery system as set forth in  claim 1  in which the pulling rods comprise a threaded rod.  
   
   
       5 . The basement wall recovery system as set forth in  claim 4  in which the pulling means comprise nuts screwed onto the outer end of the pulling rods and tightened against the pulling posts to apply a pulling force.  
   
   
       6 . The basement wall recovery system as set forth in  claim 4  in which the backing plate has a center bore, the backing plate being positioned over the inner end of the pulling rod and secured in position using a nut.  
   
   
       7 . A basement wall recovery system comprising: 
 one or more push plate(s) positioned against a building on which a basement wall is to be repaired,    one or more pulling post(s) positioned vertically outside the basement wall to be repaired with a top end resting against a push pate and a bottom end positioned against a lower base or footing of the basement wall,    one or more pulling rod(s) extending through openings in the pulling post and through the basement wall being repaired,    one or more backing plate(s) positioned on an inside end of each pulling rod, and    one or more pulling means attached to an outside end of the pulling rod(s), said pulling means exerting a force against the pulling post and onto the pulling rod, to apply pressure to the backing plate(s) to pull the backing plate against an inside surface of a bowed basement wall to pull the bowed basement wall outwards towards the pulling post and into a plume position.    
   
   
       8 . A method of repairing a bowed or concaved basement wall the steps comprising: 
 excavating the earth, as needed, along the basement wall to be repaired,    positioning one or more push plate(s) along a bottom edge of a building positioned on and above the basement wall to be repaired,    positioning one or more pulling post(s)vertically along the basement wall bing repaired with an upper end of each pulling post resting against one or two push plate(s) and a lower end positioned against a lower base area of the basement wall or a footing under the wall,    extending pull rods through bores in the pulling post and through holes bored in the basement wall with an outer end extending outwards from the pulling post and an inner end extending through the inside surface of the basement wall,    installing and securing backing plate(s) on the inner end of each pulling rod with the outer surface of the backing plate resting against the inside surface of the basement wall,    attaching a pulling means to the outer ends of each pulling rod with the pulling means positioned against the pulling posts, and    operating each pulling means to apply a pulling force on each of the pulling rods in a predetermined pattern, the pulling force applied pulling the basement wall outwards towards the pulling post until the basement wall is in a plume position, the pulling force being distributed along the pulling posts to the push plates and to the footing or base.
