Cover for prestressed concrete member

Abstract

A cover includes a body adapted to secure over a fitting disposed in a prestressed concrete member for lifting the concrete member. The body has a surface feature configured to achieve a substantially fluid tight seal with the concrete member.

1 . A cover comprising:
 a body comprising:   a surface feature configured to achieve a substantially fluid tight seal with the a concrete member having a void with a fitting disposed therein; and
 a protrusion extending from the body and configured to engage the void; 
   wherein the body is adapted to secure over the fitting disposed in a the void and engage the void for lifting the concrete member.   
   
   
       2 . The cover of  claim 1 , wherein the surface feature includes a layer of adhesive material. 
   
   
       3 . The cover of  claim 1 , wherein the surface feature is a substantially planar region. 
   
   
       4 . The cover of  claim 1 , wherein the surface feature includes a rib. 
   
   
       5 . The cover of  claim 1 , wherein the surface feature extends substantially continuously along the body. 
   
   
       6 . The cover of  claim 1 , wherein the surface feature extends outwardly from the body. 
   
   
       7 . The cover of  claim 1 , wherein the surface feature forms a recess in the body. 
   
   
       8 . The cover of  claim 1 , wherein the body includes a raised portion opposite the surface feature. 
   
   
       9 . The cover of  claim 1 , wherein the protrusion comprises a discontinuity configured to bend and reduce insertion force required to engage the void. 
   
   
       10 . The cover of  claim 9 , wherein the protrusion includes a taper. 
   
   
       11 . The cover of  claim 10 , wherein the body includes a recessed region substantially surrounding the protrusion, the recessed region disposed between the protruding portion and the surface feature. 
   
   
       12 . The cover of  claim 1 , wherein the body contains a pigment similar to a pigment of the concrete member. 
   
   
       13 . The cover of  claim 1 , wherein the body is composed of a resilient material. 
   
   
       14 . The cover of  claim 1 , wherein the body is composed of a nonmetal. 
   
   
       15 . The cover of  claim 14 , wherein a portion of the body adjacent the surface feature is resilient. 
   
   
       16 . A cover comprising:
 a body adapted to secure over a fitting disposed in a void of in a prestressed concrete member for lifting the prestressed concrete member, the body comprising:
 a surface feature configured to achieve a substantially fluid tight seal with the prestressed concrete member; 
 a protrusion portion extending from the body and configured to engage the void; and 
 a raised portion opposite the surface feature. 
   
   
   
       17 . The cover of  claim 16 , wherein the surface feature includes a layer of adhesive material. 
   
   
       18 . (canceled) 
   
   
       19 . The cover of  claim 16 , wherein the body includes a recessed region substantially surrounding protruding portion, the recessed region disposed between the protruding portion and the surface feature. 
   
   
       20 . A cover comprising a body adapted to secure over a fitting disposed in a void of a concrete member for temporarily securing an object to the concrete member,
 the body comprising:
 a surface feature configured to achieve a substantially fluid tight seal with the concrete member
 a protrusion extending from the body and configured to engage the void.
