Concrete block-out-grout tube with drain

Abstract

An elongated cylindrical tube with reinforcing ribs that can be placed within a pre-cast concrete wall section for use in joining with other wall sections having a drain preformed into the bottom of the grout tube with a nipple-like attachment positioned within the drain opening of the grout tube. The nipple-like attachment has circumferential pyramidal ridges for connecting to and retaining a water release tube allowing for the egress of any water, moisture or debris that may have collected within the grout tube to prevent deterioration or cracking of the concrete from the expansion of water freezing within the wall section or from retained debris weakening the wall connection joint.

1 . An elongated cylindrical tube member for use as a connection assisting device for joining pre-cast concrete panels or forms, said tube member comprising an integral elongate, imperforate, and hollow tubular body having a plurality of reinforcing ribs formed into the tubular body with a drain opening in the distal end of the tubular body for connecting to an elongate drain tube attached to the drain opening, said elongate drain tube extending away from the cylindrical tube member toward an exterior surface of the concrete panel or form. 
   
   
       2 . The elongated cylindrical tube of  claim 1 , wherein the plurality reinforcing ribs structurally anchor said tube within the concrete wall member and prevent the tube from rotating within and pulling out of its position in the concrete wall member, and further act to hold the grout-like hardening substance in position so that the grout will not easily move inward or outward from said tube. 
   
   
       3 . The elongated cylindrical tube of  claim 1 , further comprising a nipple-like attachment means fitted into the drain opening for retaining said elongate drain tube in position against the drain opening. 
   
   
       4 . The elongated cylindrical tube of  claim 3 , wherein the nipple-like attachment means comprises a series of circumferential pyramidal ridges for retaining the elongate drain tube onto the nipple-like attachment means. 
   
   
       5 . The elongated cylindrical tube of  claim 4 , wherein the drain opening with fitted nipple-like attachment means connecting the elongate drain tube to the drain opening allows for the egress or flushing away of any water or debris that may have collected within the tube. 
   
   
       6 . The elongated cylindrical tube of  claim 1 , wherein said drain opening includes a nipple-like attachment means integrally formed into the drain opening for retaining said elongate drain tube in position against the drain opening. 
   
   
       7 . The elongated cylindrical tube of  claim 6 , wherein the nipple-like attachment means comprises a series of circumferential pyramidal ridges for retaining the elongate drain tube onto the nipple-like attachment means. 
   
   
       8 . The elongated cylindrical tube of  claim 7 , wherein the drain opening with nipple-like attachment means connecting the elongate drain tube to the drain opening allows for the egress or flushing away of any water or debris that may have collected within the tube.
