Benefits of technology
The present invention is an elongated cylindrical grout tube with reinforcing ribs to hold it in position and provide strength to the grout / structural rod connection as it hardens. The upper end of the grout tube has an integrated bellows-like connector that can create any angle between it and the grout fill spout to facilitate the flow of grout. The grout fill spout extends outward to the surface of the pre-cast concrete wall panel to secure the upper wall segment in place by surrounding an upwardly extending structural rod positioned within the grout tube and hardening in place around the rod. The reinforcing ribs on the internal surface of the grout tube prevent interference with the structural rods during placement of the pre-cast wall segments. The invention also includes an elongated ovalized cylindrical tube member with reinforcing ribs to prevent rotation and trapped air, adding strength to the joint between wall segments. The integrated bellows-like connector seamlessly connects the tube member with the fill spout and allows for the modification of the angle between the central axis orientation of the tube member and the central axis orientation of the fill spout.
Problems solved by technology
By inverting the grout tube from its customary orientation of being cast into the top of a lower positioned precast concrete wall section, certain problems arise.
A similar problem of locating the structural rod within the range of the opening of the grout tube has previously led to the ovalization of the grout tube opening along the longitudinal direction of the precast wall section.
However, with the inverting of the grout tube to be cast into the bottom of a wall panel, although the locating of the structural rod and approximate placement of the grout tube are sufficiently resolved with the ovalization of the tube in one direction along the wall panel, the problem of properly filling the tube arises since the tube is customarily filled from the open end to the closed end using gravitational force for the grout to settle within the tube, around the structural rod, and harden in place.
If water retained in the tube freezes, there is a risk the resultant expansion will crack and ruin the panel.
Any debris collected within the spout or bellows-like connector will degrade the quality of the connection formed by the mortar when the panels are erected.
But due to the reversal of the structural members, the grout still needs to be introduced from an upper position to fill the tube properly and not cause cracking or gaps in the grout surrounding the structural rod to retain the wall section in a fixed position and not result in a potential failure of the wall integrity.

Embodiment Construction
[0020]The following detailed description is of the best presently contemplated mode of carrying out the invention. The description is not intended in a limiting sense, and is made solely for the purpose of illustrating the general principles of the invention. The various features and advantages of the present invention may be more readily understood with reference to the following detailed description taken in conjunction with the accompanying drawings.
[0021]Referring now to the drawings in detail, where like numerals refer to like parts or elements, there is shown in FIG. 1 a combination elongated ovalized grout tube 10 having a body 12, a bottom opening 14, a series of reinforcing ribs 16 in the body, a grout fill spout 18 at the top end, and an integrated bellows-like connector 20 positioned between the grout tube body 12 and the fill spout 18. The elongated body 12 is ovalized in cross-section to account for placement approximations of structural rods extending upward through t...

An inverted elongated ovalized cylindrical grout tube has reinforcing ribs to retain the tube in position in a pre-cast concrete member and to provide added strength to the grout / structural rod connection as it hardens so as to provide greater strength to a pre-cast concrete wall. The upper end of the grout tube has an integrated bellows-like connector that extends between the inverted grout tube and a grout fill spout which is capable of creating any of a number of angles between the grout tube and the fill spout to provide for the easy flow of grout into the tube from a point external to the pre-cast concrete wall.
Description
BACKGROUND OF THE INVENTION[0001]The present invention relates generally to connection devices for joining together pre-cast concrete members such as panels or columns stacked one on top of the other to form building walls. The connection devices employ an elongated ovalized cylindrical grout tube with reinforcing ribs formed into the bottom of a precast concrete member having an upward facing grout fill spout that extends through the sidewall of the precast member for permitting grout to be introduced into the inverted elongated ovalized cylindrical grout tube for securing one precast concrete member to another or fastening to the base foundation.[0002]By inverting the grout tube from its customary orientation of being cast into the top of a lower positioned precast concrete wall section, certain problems arise. A similar problem of locating the structural rod within the range of the opening of the grout tube has previously led to the ovalization of the grout tube opening along the...
