Adjustable floor to wall connectors for use with bottom chord and web bearing joists

摘要

The present invention is a light steel framed metal joist including an adjustable connector fastened to the joist web that allows one to adjust the length and angle of the joist when attaching to floor and wall systems. The adjustment allows one to install end connectors onto the joists prior to installation while retaining flexibility of orientation during construction. The joist functions in both web bearing and bottom chord bearing configurations. A flat plate distributing member allows one to design a floor system without having to coordinate the positioning of the joist with wall studs. Angle or U shaped members can be fastened to the lower portion of the flat plate distribution member to support joists during construction. The invention further provides a seamless fire stopping system with consideration for acoustic dampening.

主权项

1. An adjustable length steel joist system for use in a frame structure, comprising:
a joist, including:
a generally planar steel joist web having a web face; andat least one elongate chord joist member extending from the generally planar steel joist web; a connector connected proximate to an end of the joist, the connector made of a unitary piece of steel and including:
a connector web shaving a generally planar connector web face, a first end, and a second end opposing the first end wherein at least a portion of the connector web face is in contact with the web face of the steel joist;a connector lip extending from the first end of the connector web that is generally orthogonal to the connector web face;a stiffening lip extending from the second end of the connector web that is generally orthogonal to the connector web face, extending in the same direction as the connector lip and is generally parallel to the connector lip, the stiffening lip extending outwardly from the portion of the connector web face that is in contact with the web face of the steel joist;at least one opening in the connector lip;at least one opening in the connector web, wherein at least one of the at least one opening in the connector web is a generally elongate opening that is generally orthogonal to the connector lip and wherein the connector may be repositioned by translating and rotating the connector with respect to the at least one elongate opening; and at least one fastener inserted into at least one generally elongate opening in the connector web thereby providing a joist having an adjustable length.
