AI Technical Summary

Benefits of technology

[0008] The insert is an easy to handle and easy installable element that in combination with standardized cut web holes provides guiding and support across I-joists in accordance with specialized needs of plumbers, electricians and the like.

Problems solved by technology

Irrespective a proper cutting, the web hole may still suffer damage during the consecutive installation of pipes, tubes, and cabling at the construction site.
In an installed I-joist, web area is limited for cutting web holes.
As a common result, a multitude of pipes, tubes and / or cables tend to be cramped through a single web hole.
The resulting friction between the individual through guided elements may cause excessive lateral loads on the web, which in turn may increase the I-joist's buckling risk at the already weakened web hole location.

Embodiment Construction

[0019] An I-joist 10, a portion of which is depicted in the Figures, may be combined with an insert 20A-20F in various configurations and eventual combination with other structures, such as attachment pins 30 as in FIG. 1, thread flange 40A, 40B as in FIGS. 5-7 and / or an I-joist support 50 as in FIG. 10. Attachment pins 30 may be nails, screws and the like well known in the field of architectural construction. The insert 20A-20F provides at least one cutout contour 25 for guiding at least one of a pipe, a tube, and a cable through the web hole 13 without direct contact between the web hole 13 and said at least one of a pipe, a tube and a cable, such that the web hole 13 edges are protected against inadvertent damaging.

[0020] According to FIG. 1, a first exemplary embodiment of an insert 20A may have a flange 21 for snuggly contacting the web portion 13 of I-joist 10. The flange 21 may have a circumferential contour that at least partially complies with at least one of the bottom ch...

Abstract

An insert for I-joist web holes provides support and separation for piping, tubing and / or cabling guided through the installed I-joist's web. At the same time, the insert protects the web hole against destructive forces commonly related to the installation process and / or gravitational loads of piping, tubing and / or cabling.

Description

PRIORITY CLAIM [0001] The present invention claims priority to U.S. Provisional Application of the same title and inventor, Application No. 60 / 552,326, filed Mar. 10, 2004, which is hereby incorporated by reference. CROSS REFERENCES [0002] The present invention cross references and incorporates by reference U.S. Pat. No. 6,857,831, filed Feb. 27, 2004, titled “I-joist Hole Cutting Apparatus” and U.S. application Ser. No. 10 / 410,505, filed Apr. 8, 2003, titled “Buckling Opposing Support for I-joist”, both of the same inventor as in the present application.FIELD OF INVENTION [0003] The present invention relates to web inserts for I-joists. More particularly, the present invention relates to web inserts for supporting tubing, piping, cables and the like commonly installed across web holes of wooden I-joists in architectural constructions. BACKGROUND OF INVENTION [0004] I-joists referred in the following and in the context with the present invention are made from wood and wood like mate...
