Deck Anchor Insert

Abstract

A deck anchor insert for use in multi-story building structures with a deck form comprising an embedment portion comprising a generally round head and a threaded shaft extending from said head, an attachment assembly comprising a wing nut engaging said shaft proximal to said head; a deck retaining nut engaging said shaft adjacent to said wing nut; and a washer engaging said shaft between said wing nut and said deck retaining nut; and a coupling nut with a first end engaging said shaft adjacent to said deck retaining nut, and a second end. In some embodiments, a stop means is incorporated to prevent the stem from completely penetrating the coupling nut.

1 . A deck anchor insert for use in multi-story building structures with a deck form comprising:
 An embedment portion comprises a generally round domed head and a threaded shaft extending from said head;   an attachment assembly comprising a wing nut engaging said shaft proximal to said head; a deck retaining nut engaging said shaft adjacent to said wing nut; and a washer engaging said shaft between said wing nut and said deck retaining nut; and   a coupling nut with a first end and a second end, said first end of said coupling nut engaging said shaft and biased against said deck retaining nut to secure said coupling nut in place along said shaft.   
     
     
         2 . The deck insert of  claim 1  wherein said deck retaining nut comprises a means to lock the retaining nut against the deck form. 
     
     
         3 . The deck anchor insert of  claim 1  wherein said coupling nut comprises a single internal thread to engage said shaft, and a stop means located at an intermediate point of said internal thread to prevent said shaft from penetrating completely through said coupling nut. 
     
     
         4 . The deck anchor insert of  claim 1  wherein said coupling nut comprises a first internal thread extending from said first end of said coupling nut and a second internal thread which is counter to said first thread extending from said second end generally aligned with said first internal thread, said first and second threads meet generally in the middle of said coupling nut to prevent said shaft from penetrating completely through said coupling nut. 
     
     
         5 . The deck anchor insert of  claim 1  wherein the coupling nut comprises a first internal thread extending from said first end of said coupling nut and a second internal thread extending from said second end generally aligned with said first thread with a gap therebetween to prevent said shaft from penetrating completely through said coupling nut. 
     
     
         6 . A deck anchor insert for use in multi-story building structures with a deck form comprising:
 An embedment portion comprising a generally round domed head and a threaded shaft extending from said head;   An attachment assembly including a wing nut engaging said shaft proximal to said head; a deck retaining nut engaging said shaft adjacent to said wing nut; and a washer engaging said shaft located between said wing nut and said deck retaining nut;   a coupling nut with a first end and a second end, said first end of said coupling nut engaging said shaft and biased against said deck retaining nut to secure said coupling nut in place along said shaft; and   a stop means to prevent the shaft from penetrating completely through said coupling nut.   
     
     
         7 . The deck insert of  claim 6  wherein said deck retaining nut comprises a means to lock the retaining nut against the deck form. 
     
     
         8 . The deck anchor insert of  claim 6  wherein said stop means comprises a single thread extending from said first end through said second end to engage said shaft with a stop located on said internal thread preventing said shaft from penetrating completely through said coupling nut. 
     
     
         9 . The deck anchor insert of  claim 6  wherein said stop means comprises a first internal thread extending from said first end of said coupling nut and a second internal thread which is counter to said first thread extending from said second end generally aligned with said first internal thread and meeting generally in the middle of said coupling nut thereby preventing said shaft from penetrating completely through said coupling nut. 
     
     
         10 . The deck anchor insert of  claim 6  wherein said stop means comprises a first internal thread extending from said first end of said coupling nut and a second internal thread extending from said second end generally aligned with said first thread with a gap between said first and second internal threads generally at the middle thereby preventing said shaft from penetrating completely through said coupling nut. 
     
     
         11 . A method for installing a deck anchor insert, comprising an embedment portion comprising a generally round head and a threaded shaft extending from said head, an attachment assembly comprising a wing nut engaging said shaft proximal to said head; a deck retaining nut engaging said shaft adjacent to said wing nut; and a washer engaging said shaft between said wing nut and said deck retaining nut; a coupling nut with a first end and a second end, said first end of said coupling nut engaging said shaft and biased against said deck retaining nut to secure said coupling nut in place along said shaft, comprising:
 Forming a hole in a deck form;   Inserting said deck anchor insert into said hole;   Shifting said deck anchor sideways to insert said deck form between said washer and said retaining nut;   Aligning said washer to cover said hole to prevent concrete seepage during pouring;   Tightening said wing nut against said washer to secure said deck form between said washer and said retaining nut; and   Pouring concrete into said deck form, around and over said deck anchor insert.
