Abstract

A conduit sleeve for a concrete pass through includes a tubular member having an inside diameter for receiving a cylindrical conduit at a forward end thereof. A flange is coupled to a rearward end of the tubular member. The flange is for coupling to a concrete form. A flexing structure is coupled to one or more of the tubular member and the flange for allowing the flange to be angled relative to the tubular member when the flange is installed on a concrete form. The tubular member is configured for receiving a conduit and the flexing structure allows the conduit to remain horizontal when there are variations in the angle of the form. Another conduit sleeve includes a coupling part, a flange, and a plurality of tabs that extend outwardly from the flange.

Claims

1. A conduit sleeve for a concrete pass through comprising:

a tubular member having a forward end, a rearward end, and an inside diameter for receiving a cylindrical conduit at the forward end;

a flange coupled to the rearward end of the tubular member, said flange for coupling to a concrete form; and

a pivoting structure coupling the tubular member with the flange for allowing the flange to be angled relative to the tubular member.

2. The conduit sleeve of claim 1, wherein the pivoting structure comprises a pleat.

3. The conduit sleeve of claim 2, wherein the pleat is positioned on the tubular member.

4. The conduit sleeve of claim 2, wherein the pivoting structure comprises two or more pleats.

5. The conduit sleeve of claim 4, wherein a first pleat has a first inner diameter and a second pleat has a second inner diameter, and the first and second inner diameters are different from one another.

6. The conduit sleeve of claim 2, wherein the pleat faces rearward of the flange, the flange has a central portion that is removable in order to expose an interior of the tubular member, and the pleat is positioned adjacent the central portion of the flange.

7. The conduit sleeve of claim 1, wherein the pivoting structure permits the tubular member to be angled up to 30 degrees relative to the plane of the flange.

8. The conduit sleeve of claim 1, wherein the flange includes a top portion, a bottom portion, a thinned portion defined between the top portion and the bottom portion, and a central portion that is removable to expose an interior of the tubular member, with the thinned portion providing a fold line where the top portion may be folded over the concrete form at an angle relative to the bottom portion.

9. The conduit sleeve of claim 1, further comprising a plurality of forwardly facing tabs coupled to the flange.

10. The conduit sleeve of claim 9, wherein the tabs are positioned around at least part of the periphery of the flange and extend at an angle relative to a plane of the flange.

11. The conduit sleeve of claim 10, wherein the angle of the tabs relative to the plane of the flange is other than 90 degrees.

12. The conduit sleeve of claim 9, further comprising a plurality of fingers corresponding to the plurality of tabs, with each finger projecting from a corresponding tab at an angle to the corresponding tab.

13. The conduit sleeve of claim 1, wherein the flange includes a plurality of through holes for receiving a fastener to couple the flange to the concrete form and further comprising a recessed portion that surrounds each hole and that allows a fastener to slip through the hole upon application of sufficient force.

14. A conduit sleeve system for defining a pass through in a concrete structure, comprising:

first and second conduit sleeves having first and second tubular members, first and second flanges, and first and second pivoting structures according to claim 1; and

a conduit positioned between the first and second conduit sleeves, wherein a first end of the conduit is positioned in the first tubular member of the first conduit sleeve, a second end of the conduit is positioned in the second tubular member of the second conduit sleeve, and the first flange of the first conduit sleeve faces in a first direction, the second flange of the second conduit sleeve faces in a second direction, and the first and second directions are opposite one another.
