Slab anchor encapsulation assembly

Abstract

The present disclosure provides a slab anchor assembly that has an anchor body with a tendon-receiving area and a grout passage, being located at a center point of the anchor body and of the tendon receiving area and extending through the anchor body. The anchor body can be encapsulated. The slab anchor assembly further includes a grout cap having a centrally located and threaded grout hole extending therethrough, the grout cap being configured for securement to a trumpet assembly exterior to and in engagement with the anchor body with a blockout, which may be encapsulated, located between the grout cap and the anchor body. The grout hole and the grout passage may be coaxial so as to form a straight channel. Further, the assembly may include liquid-tight seals between components.

What is claimed is: 
     
         1 . An assembly, comprising:
 an anchor body comprising a tendon-receiving area and a grout passage extending through a center of the anchor body; and   a grout cap having a threaded grout hole extending through a center of the grout cap; and   a blockout that is configured to be located between the grout cap and the anchor body.   
     
     
         2 . The assembly of  claim 1 , wherein the tendon-receiving area of the anchor body comprises four ports to receive four tendons. 
     
     
         3 . The assembly of  claim 1 , wherein the anchor body is bare. 
     
     
         4 . The assembly of  claim 1 , wherein the anchor body is encapsulated. 
     
     
         5 . The assembly of  claim 1 , further comprising:
 a trumpet assembly that is configured for securement on one end to the grout cap through the anchor body and on an opposite end to a duct.   
     
     
         6 . The assembly of  claim 5 , wherein the grout cap is configured for securement to the trumpet assembly by two bolts that pass through the grout cap, through the blockout and then through the anchor body and mate with corresponding bolt holes located in the trumpet assembly. 
     
     
         7 . The assembly of  claim 5 , wherein the trumpet assembly comprises a weld-in grout port. 
     
     
         8 . The assembly of  claim 1 , further comprising:
 a snap-in grout port configured to mate with the grout passage in the grout cap.   
     
     
         9 . The assembly of  claim 5 , wherein the trumpet assembly is configured for securement to the duct via a clamp. 
     
     
         10 . The assembly of  claim 1 , wherein the threaded grout hole and the grout passage are coaxial so as to form a straight channel. 
     
     
         11 . An assembly, comprising:
 an anchor body comprising a tendon-receiving area and a grout passage, the grout passage being located at a center point of the anchor body and of the tendon-receiving area and extending through the anchor body;   a grout cap having a centrally located and threaded grout hole extending therethrough a center portion; and   a trumpet assembly that is configured for securement on one end to the grout cap and the anchor body and on an opposite end to a duct.   
     
     
         12 . The assembly of  claim 11 , wherein the grout hole and the grout passage are coaxial so as to form a straight channel. 
     
     
         13 . The assembly of  claim 11 , further comprising a liquid-tight seal between the grout cap and the anchor body and the anchor body and the trumpet. 
     
     
         14 . The assembly of  claim 11 , wherein the tendon-receiving area comprises four passages arranged in a square pattern around the grout passage, each of the four passages extending through the anchor body. 
     
     
         15 . The assembly of  claim 11 , further comprising:
 a weld-in grout port configured to be mounted to the trumpet.   
     
     
         16 . The assembly of  claim 11 , further comprising:
 a snap-in grout anchor adaptor configured to be mounted to the grout passage and forming a grout channel between the grout hole and the grout passage.   
     
     
         17 . The assembly of  claim 11 , wherein the grout cap is configured for securement to the trumpet assembly by two bolts that pass through the grout cap then through the anchor body and mate with corresponding bolt holes located in the trumpet assembly. 
     
     
         18 . The assembly of  claim 11 , wherein the trumpet assembly is configured for securement to the duct via a clamp. 
     
     
         19 . The assembly of  claim 11 , further comprising:
 a blockout configured to be located between the grout cap and the anchor body.
